Description

Technical Field

Carrier aggregation (CC, carrier Congregate) is a key technology for supporting larger bandwidths in future wireless communication systems, and forms carriers of larger bandwidths by aggregating carriers of different types and/or sizes.

Currently, in order to support a UE with a stronger capability on the aggregated bandwidth, for the control channel, such as the carrying capability of the physical downlink control channel, especially when the interference type and the interference strength on the 5G macro cell change, the component carriers allocated on the Uplink (UL) and/or the Downlink (DL) generally adopt an asymmetric duplex manner of component carrier resources.

The method for controlling the channel performance on carrier aggregation provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the base station 101 via a network. The base station 101 receives measurement information sent by the terminal 102, wherein the measurement information comprises an interference type, an interference strength and a service type and a size, the base station 101 selects component carrier resources conforming to the service type and the size of the terminal from different component carrier type sets according to the measurement information and corrects a function field of a control channel performance improvement signaling on carrier aggregation, the base station 101 distributes the component carrier resources to the terminal 102 and the control channel performance improvement signaling on carrier aggregation, and the control channel performance improvement signaling on carrier aggregation is used for indicating the terminal 102 to finish service receiving and sending of carrier aggregation and blind decoding according to the configuration of the function field in the control channel performance improvement signaling on carrier aggregation. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, where the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, projection devices, and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The head-mounted device may be a Virtual Reality (VR) device, an augmented Reality (Augmented Reality, AR) device, smart glasses, or the like. Base station 101 may be a gNB (5G base station).

In an exemplary embodiment, as shown in fig. 2, a method for controlling channel performance on carrier aggregation is provided, and an example of application of the method to the base station in fig. 1 is described, which includes the following steps 201 to 203. Wherein:

Step 201, receiving measurement information sent by a terminal.

The measurement information comprises an interference type, an interference strength, and a service type and a service size. In an alternative embodiment, before executing step 201, the base station first initializes the function field of the control channel performance improvement signaling on the carrier aggregation to complete any one or any multiple of 1) completing the allocation of the component carrier types on the macrocell by initializing the component carrier type allocation field, 2) predefining blind decoding thresholds for different component carrier type sets by initializing the component carrier blind decoding number control policy field, 3) completing the blind decoding specification of the component carrier type sets on the macrocell by initializing the component carrier blind decoding mode selection field, 4) completing the specification on the component carrier type sets on the macrocell by initializing a downlink control information format and searching an interval control field, 5) setting the mapping relation to be unmapped by initializing the component carrier mapping relation confirmation field, and 6) completing the control channel performance improvement feedback field on the macrocell by initializing the component carrier aggregation to indicate that the initialization is completed.

It should be noted that, the present embodiment is not limited to the above-mentioned initialization sequence, and only some of the fields may be initialized, if the wireless communication system itself may retain the previous setting, or the above-mentioned initialization step may be skipped, and step 201 may be directly executed.

Step 202, according to the measurement information, selecting component carrier resources conforming to the terminal service type and size from different component carrier type sets, and correcting the function field of the control channel performance improvement signaling on carrier aggregation.

As shown in fig. 3, the control channel performance enhancing signaling on carrier aggregation is divided into a plurality of functional fields, where the functional fields include any one of, or any multiple of, a component carrier type allocation field, a component carrier blind decoding number control policy field, a component carrier blind decoding mode selection field, a downlink control information format and search interval control field, a component carrier mapping relation confirmation field, and a control channel performance enhancing feedback field on carrier aggregation.

The component carrier type allocation field is configured to divide all component carriers into different types according to interference types and intensities in different areas of the macro cell, uplink (UL) and/or Downlink (DL) component carrier payload sizes, component carrier resource duplexing modes on Uplink (UL) and/or Downlink (DL) of a User Equipment (UE), signaling interaction overhead, and the like. It should be noted that the basis for dividing the component carrier types is not limited to the above-listed manner.

Fig. 4 is a schematic diagram of a network architecture of a method for controlling channel performance on carrier aggregation in an embodiment, as shown in fig. 4, in a macro cell including a1 st cell, a 2 nd cell, and a 3 rd cell, at least one base station (gNB 1, gNB2, and gNB 3) is disposed in each cell, and a plurality of clients (UE 1, UE2, UE3, UE4, and UE 5) are distributed in the macro cell, where the clients may change. And the different base stations correspond to one control channel, and carrier resource allocation is carried out on the user side in the macro cell. Taking fig. 4 as an example, the interference types in different areas in the macro cell can be classified into 6 types, namely inter-subband cross-link interference (CLI) from the gNB to the gNB, inter-subband cross-link interference (CLI) between user terminals (UEs) in the cell, interference of the user terminals (UE) in the cell to the gNB of other adjacent cells, interference of the gNB in the cell to the user terminals (UE) in the adjacent cells, and new inter-cell strong interference caused by cell identity collision. The inter-subband cross-link interference (CLI) between the gNB and the gNB in the interference type 1 refers to the interference of the gNB receiver from another gNB transmitter, and the inter-subband cross-link interference (CLI) between the User Equipments (UEs) in the interference type 2 refers to the influence of the User Equipments (UEs) transmitting on non-overlapping resources in the same cell on another User Equipment (UE). Inter-subband cross-link interference (CLI) between inter-cell UEs refers to the influence of UE transmission on non-overlapping resources in neighboring cells on another UE. The interference type 4, that is, interference of a User Equipment (UE) between cells to a gcb of other adjacent cells, refers to that the transmission of the UE in one cell interferes with the Uplink (UL) reception of the gcb of the other cells. The interference type 5, that is, interference of gNB between cells to a user terminal (UE) of a neighboring cell, refers to Downlink (DL) receiving interference of gNB in one cell to a user terminal (UE) of other cells. The interference type 6 is that the strong interference among new cells caused by the cell identity conflict is that when the cell identity conflict, the user terminal (UE) at the edge of the cell is subjected to the strong inter-cell interference caused by gNB with the same identity of the adjacent cell, and because the cell identity conflict causes a plurality of gNB to the same user terminal (UE), different interference suppression modes are used when the gNB is positioned at different positions in different cells, the user terminal (UE) is simultaneously subjected to the strong interference of different types.

Illustratively, uplink (UL) and/or Downlink (DL) component carrier payload sizes include, but are not limited to, uplink (UL) enhancements where the Uplink (UL) component carrier size is greater than the Downlink (DL) component carrier size, downlink (DL) enhancements where the Downlink (DL) component carrier size is greater than the Uplink (UL) component carrier size, and Uplink (UL) equalizations where the Uplink (UL) component carrier size is equal to the Downlink (DL) component carrier size. Exemplary means for duplexing component carrier resources on the Uplink (UL) and/or Downlink (DL) of a User Equipment (UE) include, but are not limited to, uplink (UL) component carrier full duplex/Downlink (DL) component carrier full duplex, uplink (UL) component carrier full duplex/Downlink (DL) component carrier half duplex, uplink (UL) component carrier half duplex/Downlink (DL) component carrier full duplex, uplink (UL) component carrier half duplex/Downlink (DL) component carrier half duplex.

For the purpose of more clearly illustrating relevant details of the component carrier types, a first type is illustrated, wherein the details of the component carrier include 1) all component carriers have no main interference type, 2) the maximum interference intensity of all component carriers is lower than a threshold value preset by gNB, 3) the size and duplex mode allocation of the component carriers are not limited, and 4) gNB uses the same interference suppression strategy for the component carriers of the same type, so that algorithm complexity and signaling cost in gNB interference suppression are remarkably reduced. The second type of component carrier size limiting type, wherein the component carrier details comprise 1) that the sizes of all component carriers are in a range preset by gNB when the component carriers are selected, wherein the size comprises a maximum component carrier size and/or a minimum component carrier size so as to reduce the complexity of gNB in scheduling the same type of component carriers, 2) gNB can allocate different component carrier size limiting types, is used for gNB to set different component carrier size sets according to the component carrier sizes, and 3) gNB can select the component carrier carriers from the different component carrier size sets to realize component carrier allocation for a user side (UE). The third type is a composite component carrier duplex mode, and the details of the component carriers include 1) gNB presets the duplex modes of all component carrier resources on a macro cell as default values, wherein the default values can be full duplex or half duplex, but are not limited to the default values, 2) gNB sets different component carrier duplex mode sets according to the component carrier duplex mode, and 3) when gNB changes the component carrier duplex mode on the component carrier duplex mode set, gNB re-divides the changed component carrier into the duplex mode sets. The fourth type is component carrier equalization, and the details of the component carriers comprise 1) allocation of component carrier types defaulted by gNB, 2) specification of the types of the component carriers by gNB according to the natural sequence and/or the random sequence of all component carrier resources on a macro cell, and 3) non-specification of interference, carrier size and duplex mode of the component carriers, thereby reducing the specification difficulty of the component carrier types.

When the gNB determines the component carrier type allocation field of the component carrier used by the User Equipment (UE), the first mode may be a pre-allocation mode, where the gNB defines the component carrier types of all component carriers on the macro cell by using the various types shown in the above embodiment, and selects, from the determined component carrier type set, component carriers that conform to the interference type, the component carrier size, and the component carrier duplex mode of the User Equipment (UE) according to the information such as the location of the User Equipment (UE) on the macro cell. The method has the advantages of simple component carrier resource allocation algorithm, small signaling interaction overhead and small number of Blind Decoding (BD). In the second mode, the gNB randomly selects the component carrier resources to the user terminal (UE), the user terminal (UE) uses the allocated component carrier resources to perform interference measurement and feeds back the interference measurement to the gNB, and the gNB determines the component carrier types of all the component carrier resources allocated to the user terminal (UE) according to the interference type and/or the interference intensity, the component carrier size and the component carrier duplex mode. The method has the advantage that the utilization rate of the component carrier resources can be greatly improved. And the third mode is a mixed allocation mode, wherein gNB predicts the interference types and/or the interference intensities at all positions on the macro cell and predicts the component carrier sizes and the duplex mode demands of the existing user terminals (UE) on the macro cell. The component carrier types of the partial component carrier resources are preset according to the various types shown in the above embodiments, and the component carrier resources of the remaining unassigned component carrier types are assigned in a random manner. When the gNB allocates the component carrier resources to the user terminal (UE), the user terminal (UE) in the area with the interference type and/or the interference intensity lower than the preset threshold value on the macro cell firstly adopts the component carrier allocation on the component carrier set allocated in a random mode, and the utilization rate of the component carrier resources is improved as much as possible under the condition of ensuring the communication quality. And if the allocation of the component carrier resources is not completed, the gNB selects the component carrier resources again on the pre-allocated component carrier set to complete the allocation of the component carrier resources. For a User Equipment (UE) in an area with interference type and/or interference strength higher than a preset threshold on a macro cell, component carrier resources are selected again on a pre-allocated component carrier set. And if the allocation of the component carrier resources is not finished, adopting the component carrier allocation on the component carrier set allocated in a random mode to finish the allocation of the component carrier resources. Thereby improving the communication quality of the User Equipment (UE) with high interference type and/or interference intensity as much as possible and reducing the number of Blind Decoding (BD) as much as possible. The component carrier blind decoding number control policy field is configured to allocate different blind decoding numbers according to component carrier types, so that the gNB calculates the total number of Blind Decoding (BD) by using a weighted average mode on different types of component carriers allocated to the gNB on the basis that the total number of Blind Decoding (BD) on all component carrier resources occupied by a User Equipment (UE) is kept unchanged, thereby significantly reducing the number of blind decoding and further significantly reducing the traffic blocking rate.

For example, for different component carrier types, the gNB may set different total thresholds of Blind Decoding (BD), and the gNB may be flexibly set according to a service requirement of a User Equipment (UE) on the macrocell. For example, the gNB presets that the component carrier sets of different component carrier types have different total Blind Decoding (BD) thresholds, wherein all component carriers on the same component carrier type set have the same total Blind Decoding (BD) threshold. The distribution method has the advantages of simple distribution algorithm and small signaling interaction cost. The threshold total number of Blind Decodes (BD) for all allocated component carriers may also be reassigned after the gNB is allocated to the User End (UE) component carrier. The allocation method has the advantages that the position of the User Equipment (UE) on the macro cell can be predicted and tracked, the type of the component carrier of the allocated component carrier resources can be corrected at any time, and the total threshold of the Blind Decoding (BD) of the component carrier is changed to match the performance of the User Equipment (UE) and maximize the performance. The component carrier blind decoding mode selection field is used for indicating that the gNB presets the blind decoding modes of all component carrier resources on the macro cell, and reassigns the blind decoding modes after the gNB allocates the component carrier resources used by a User Equipment (UE). For example, it may be exhaustive, define the number of blind decodes on different types of component carriers, etc. The present embodiment may also use a certain priority policy when setting the number of blind decodes, but the present embodiment is not limited to the above-described manner.

For example, the gNB may pre-specify that different component carrier type sets have different blind decoding manners according to the component carrier type allocation field. Meanwhile, the gNB counts the number of successful/failed actual Blind Decoding (BD) on different component carrier type sets, and if the User Equipment (UE) successfully completes the Blind Decoding (BD) on a preset total Blind Decoding (BD) threshold value, the gNB keeps the number control strategy field of the component carrier Blind Decoding (BD) of the component carrier type unchanged. If the UE does not complete the Blind Decoding (BD) above a preset threshold of the total number of Blind Decoding (BD), the gNB first modifies the Blind Decoding (BD) mode specified by the component carrier blind decoding mode selection field according to the counted total number of Blind Decoding (BD). If the Blind Decoding (BD) is not completed successfully, the gNB uses the total threshold value of the Blind Decoding (BD) preset by the modified component carrier Blind Decoding (BD) quantity control strategy field as a new predicted value. The gNB re-counts the number of Blind Decoding (BD) of the User Equipment (UE) and finally completes the blind decoding prediction of the User Equipment (UE). The downlink control information (DCI, downlink Control Information) format and the search interval control field are used for indicating that the gNB presets all Downlink Control Information (DCI) according to all component carrier types on the macro cell, and can also determine the total number of Downlink Control Information (DCI) formats on all allocated component carrier resources according to the interference type and strength of the User Equipment (UE), the Uplink (UL) and/or Downlink (DL) component carrier payload size, the duplex mode of the component carrier resources on the User Equipment (UE) Uplink (UL) and/or Downlink (DL) when allocating component carrier resources for the User Equipment (UE), and for the same Downlink Control Information (DCI) format, the gNB uses the same search interval to complete Blind Decoding (BD) of the component carrier, so as to significantly reduce the number of Blind Decoding (BD) on a single search interval and further reduce the traffic blocking rate. The component carrier mapping relationship confirmation field is configured to instruct the gNB to determine a mapping relationship and a duplex matching relationship on Uplink (UL) and/or Downlink (DL) component carriers on all component carrier resources allocated and occupied by a User Equipment (UE). The feedback field for improving the performance of the control channel on carrier aggregation is used for performing state confirmation and signaling interaction when the method for improving the performance of the control channel on carrier aggregation in this embodiment is implemented between the gNB and/or a User Equipment (UE).

The method comprises the steps of obtaining measurement information sent by a terminal, correcting a function field of a control channel performance improvement signaling on carrier aggregation, wherein the function field comprises any one or more operations of correcting a control strategy field of the blind decoding number of component carriers for indicating the determined blind decoding number on a component carrier set selected for use by the terminal, correcting a component carrier mapping relation confirmation field for indicating the mapping relation of an uplink and/or a downlink of component carrier resources used by the terminal, and correcting a control channel performance improvement feedback field on carrier aggregation for indicating that the state of the component carrier resources is allocated to be confirmed.

Step 203, allocating component carrier resources to the terminal, and performing control channel performance improvement signaling on carrier aggregation.

In this embodiment, the control channel performance enhancing signaling on carrier aggregation is used to instruct the terminal to complete the service receiving and sending of carrier aggregation and blind decoding according to the configuration of the function field in the control channel performance enhancing signaling on carrier aggregation.

In another exemplary embodiment, as shown in fig. 5, a method for controlling channel performance on carrier aggregation is provided, and the method is applied to the base station in fig. 1 for illustration, and includes the following steps 501 to 509. Wherein:

step 501, receiving measurement information sent by a terminal.

Step 502, according to the measurement information, selecting component carrier resources conforming to the terminal service type and size from different component carrier type sets, and correcting the function field of the control channel performance improvement signaling on carrier aggregation.

In step 503, component carrier resources are allocated to the terminal, and control channel performance improvement signaling is performed on carrier aggregation.

In this embodiment, the specific implementation process and technical effects of steps 501 to 503 are shown in fig. 2, and the description of steps 201 to 203 is omitted here.

And step 504, receiving feedback information of whether the blind decoding is successful or not sent by the terminal and the corresponding total number of blind decoding.

In this embodiment, the feedback information is used to characterize whether the terminal completes blind decoding according to the control channel performance improvement signaling on carrier aggregation issued by the base station, and the total number of blind decoding.

In step 505, if feedback information of blind decoding failure is received, it is determined whether the total number of blind decoding exceeds a preset threshold.

In this embodiment, if feedback information sent by the terminal is received to indicate blind decoding failure, it is first determined whether the total number of blind decoding exceeds a preset threshold, and if the total number of blind decoding does not exceed the preset threshold, it is indicated that the reason for the blind decoding failure is not due to the fact that the function field configured in the control channel performance improvement signaling on carrier aggregation is not adapted. At this time, the control channel performance improvement signaling on carrier aggregation is not required to be corrected, and the control channel performance improvement signaling on carrier aggregation is sent to the terminal again to try second blind decoding.

If the preset threshold is exceeded, step 506 is executed if there is an untried blind decoding method, if yes, step 507 is executed, and if not, step 508 is executed.

In this embodiment, if the total number of blind decoding exceeds a preset threshold, it is first determined whether all the blind decoding modes are exhaustive, and if not, it is possible to first attempt to change the current blind decoding mode to an untried blind decoding mode.

Step 507, after correcting the control channel performance improvement signaling on carrier aggregation to indicate to change the currently used blind decoding mode, step 509 is executed.

In this embodiment, the gNB modifies the currently used Blind Decoding (BD) scheme by modifying the component carrier blind decoding scheme selection field of the control channel performance improvement signaling on carrier aggregation.

Step 508, modify the control channel performance improvement signaling on carrier aggregation to indicate changing the control strategy for blind decoding.

In this embodiment, the control strategy includes changing a threshold of total blind decoding numbers and/or blind decoding weights of different types of component carriers. Illustratively, the gNB alters the threshold of the total number of Blind Decodes (BD), the weight of Blind Decodes (BD) of different types of component carriers, etc. by correcting the number control policy field of the component carrier Blind Decodes (BD) of the control channel performance improvement signaling on the carrier aggregation, but is not limited thereto.

Step 509, the modified control channel performance improvement signaling on carrier aggregation is sent to the terminal again.

In this embodiment, whether the terminal successfully completes the blind decoding is determined by receiving feedback information sent by the terminal, if the blind decoding is not successfully completed, the reason of the blind decoding failure is sequentially checked, and the blind decoding mode and the control strategy are changed by correcting control channel performance improving signaling on carrier aggregation, so that the number of blind decoding on a single search interval can be obviously reduced on the premise of ensuring the total number of blind decoding, signaling interaction overhead between the base station and the user terminal is reduced, and further, the service blocking rate is reduced.

In yet another exemplary embodiment, as shown in fig. 6, a method for controlling channel performance on carrier aggregation is provided, and the method is applied to the base station in fig. 1, for example, and includes the following steps 601 to 608. Wherein:

And step 601, receiving measurement information sent by a terminal.

Step 602, according to the measurement information, selecting component carrier resources conforming to the terminal service type and size from different component carrier type sets, and correcting the function field of the control channel performance improvement signaling on carrier aggregation.

Step 603, allocating component carrier resources to the terminal, and performing control channel performance improvement signaling on carrier aggregation.

In this embodiment, the specific implementation process and technical effects of steps 601 to 603 are shown in fig. 2, and the description of steps 201 to 203 is omitted here.

Step 604, receiving feedback information of whether the blind decoding fed back by the terminal is successful or not, and a corresponding total number of blind decoding.

Step 605, if feedback information of blind decoding failure is received, it is determined whether the downlink control information format and the search interval are still not tried, if yes, step 606 is executed, and if no, step 607 is executed.
