Please refer to FIG. 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. As shown in FIG. 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several UEs 11 and several access devices 12 .

Wherein, UE 11 may be a device that provides voice and/or data connectivity to a user. UE 11 can communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and UE 11 can be an Internet of Things UE, such as a sensor device, a mobile phone (or called a "cellular" phone) and a The computer of the IoT UE, for example, may be a fixed, portable, pocket, hand-held, built-in computer or vehicle-mounted device. For example, a station (Station, STA), a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a mobile station (mobile), a remote station (remote station), an access point, a remote UE ( remote terminal), access UE (access terminal), user equipment (user terminal), user agent (user agent), user equipment (user device), or user UE (user equipment, UE). Alternatively, UE 11 may also be a device of an unmanned aerial vehicle. Alternatively, the UE 11 may also be a vehicle-mounted device, for example, a trip computer with a wireless communication function, or a wireless communication device connected externally to the trip computer. Alternatively, the UE 11 may also be a roadside device, for example, it may be a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

The access device 12 may be a network side device in a wireless communication system. Wherein, the wireless communication system may be a fourth generation mobile communication technology (the4th generation mobile communication, 4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; or, the wireless communication system may also be a 5G system, also known as a New air interface (new radio, NR) system or 5G NR system. Alternatively, the wireless communication system may also be a next-generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, New Generation Radio Access Network). Or, the MTC system.

Wherein, the access device 12 may be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 may also be an access device (gNB) adopting a centralized and distributed architecture in the 5G system. When the access device 12 adopts a centralized and distributed architecture, it generally includes a central unit (central unit, CU) and at least two distributed units (distributed units, DU). The centralized unit is provided with a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a media access control (MediaAccess Control, MAC) layer protocol stack; the distribution unit A physical (Physical, PHY) layer protocol stack is set in the device, and the embodiment of the present disclosure does not limit the specific implementation manner of the access device 12 .

Due to the limitation of time-frequency domain resources for scheduling, Redcap UE needs to indicate in advance, that is, the type of terminal can be identified during the random access process, which is convenient for reasonable scheduling.

Early terminal-based identification is performed through random access channel partition (RACH partition). Resources to be randomly accessed are divided according to combinations of features to be supported (Feature combination).

A part of the characteristics are divided in the random access resource RACH-ConfigCommon used by 4-step RACH and/or the random access resource RACH-ConfigCommonTwoStepRA used by two-step random access (2-step RACH). The combination preamble table (featureCombinationPreamblesList) is used for a specific feature combination, such as for the Redcap UE of 3GPP standard 17 (R17). At this time, the allocated resources for the R17 Redcap UE are respectively used for the msg1 early indication of the 4-step random access of the R17 Redcap or the early indication of msgA of the two-step random access.

During the random access process of the R17 Redcap UE, an early indication can be configured, and the R17 Redcap UE will preferentially use the resources indicated earlier.

If the network configures the early indication of msg1 of R17 Redcap or the early indication of msgA, the network can immediately determine that the type of UE is the Redcap of R17 after receiving msg1 or msgA. Thereafter, in the scheduling of msg2 or msgB, an appropriate scheduling method different from that of regular users (such as eMBB UE) may be selected to achieve precise scheduling.

3GPP standard 18 introduces enhanced reduced capability (enhance Reduced capability, eRedcap) UE, eRedcap UE uplink data transmission bandwidth is limited to 5Mhz, so for the random access resource configuration used in two-step random access, the configuration in MsgA-PUSCH-Config The frequency domain range (nrofPRBs-PerMsgA-PO) of msgA PUSCH will exceed the uplink support bandwidth of R18 terminals; therefore, when eRedcap UE performs two-step random access, msgA PUSCH cannot be successfully decoded at the base station.

Therefore, how to configure random access resources for the eRedcap UE and improve the random access success rate of the eRedcap UE is an urgent problem to be solved.

As shown in FIG. 2, an embodiment of the present disclosure provides an information transmission method, which is executed by a network side device, including:

Step 201: Determine the resource configuration information of the first random access resource of the first type of Redcap UE, wherein the first random access resource is determined by the second type of Redcap UE based on a predetermined method. The UE uses, wherein, the data transmission bandwidth of the first type of Redcap UE is greater than or equal to that of the second type of Redcap UE.

The network side equipment may include at least one of the following: core network equipment; access network equipment (such as a base station)

The first type of RedCap UE may be the Redcap UE introduced by the 3GPP standard 17.

In a possible implementation manner, the data transmission bandwidth of the first type of RedCap UE is less than or equal to 20 MHz. For example, the data transmission bandwidth of the first type of RedCap UE can be up to 20MHz.

The second type of RedCap UE may be the eRedcap UE introduced by the 3GPP standard 18.

In a possible implementation manner, the data transmission bandwidth of the second type of RedCap UE is less than or equal to 5 MHz. For example, the downlink data transmission bandwidth of the first and second types of RedCap UEs may be 20 MHz, but the uplink data transmission bandwidth may be up to 5 MHz.

The first random access resources include at least one of the following items: random access resources for 4-step access; random access resources for two-step access.

In a possible implementation manner, the first random access resource includes the transmission resource of msgA in the two-step access.

The network side device may configure the first random access resource and determine resource configuration information before the UE performs random access.

Since the data transmission bandwidth of the first type of RedCap UE is less than 20 MHz, the data transmission bandwidth of the second type of Redcap UE is covered. Therefore, if the configured transmission bandwidth of the first random access resource configured for the first type of Redcap UE meets the requirements of the second type of Redcap UE, it can also be used by the second type of Redcap UE.

In one embodiment, if the data receiving bandwidth of the second type of Redcap UE can be enlarged to 20Mhz during the random access process, then the random access resources configured for the first type of Redcap user can be used by the second type of Redcap UE in the random access process. used in random access.

In a possible implementation manner, whether the first random access resource is used by the second type of Redcap UE may include one of the following items:

All resources of the first random access resource can be used by the second type of RedCap UE;

Part of the first random access resources can be used by the second type of RedCap UEs.

The predetermined method includes but is not limited to the following: determine whether the first random access resource is used by the second type of Redcap UE through the communication protocol; determine whether the first random access resource is used by the second type of Redcap UE through the indication information by the network side equipment use.

Whether the first random access resource is used by the second type of Redcap UE may be predefined, or may be determined by the network side device based on the configured first random access resource.

In a possible implementation manner, if the first random access resource is used by the second type of Redcap UE, the network side device may configure the first random access resource based on the first random access resource being used by the second type of Redcap UE.

For example: if the first random access resource can be used by the second type of Redcap UE, then the first random access resource configured by the network device needs to meet the bandwidth capability of the second type of Redcap UE (that is, the data transmission bandwidth is less than or equal to 5MHz) .

If the first random access resource cannot be used by the second type of Redcap UE, then the network device configures the first random access resource to ignore the bandwidth capability of the second type of Redcap UE (that is, the data transmission bandwidth is less than or equal to 5MHz), and only configures The first random access resource that can satisfy the bandwidth capability of the first type of Redcap UE (that is, the data transmission bandwidth is less than or equal to 5MHz).

The second type of Redcap UE may determine whether to use the first random access resource to perform random access based on a predetermined method.

In this way, the first random access resource configured by the network side device, the second type of RedCap UE can determine whether it can be used by the second type of Redcap UE in a predetermined manner. The uncertainty of using the first random access resource by the second type of Redcap UE is reduced, and the random access success rate of the second type of Redcap UE is improved.

As shown in FIG. 3 , an embodiment of the present disclosure provides an information transmission method, which is executed by a network side device, including:

Step 301: Send resource configuration information indicating the first random access resource.

The network side device may send resource configuration information to the UE before the UE performs random access (including 4-step access or 2-step access).

In a possible implementation manner, the network side device broadcasts the resource configuration information to the UE. For example, resource configuration information may be carried in system messages.

In a possible implementation manner, the resource configuration information may be carried in the MsgA-PUSCH-Config field.

In an embodiment, whether the first random access resource is used by the second type of Redcap UE is determined by the second type of Redcap UE based on a communication protocol.

Here, whether the first random access resource is used by the second type of Redcap UE may be specified by the communication protocol.

Exemplarily, if the communication protocol stipulates that the first random access resource can be used by the second type of Redcap UE, then the first random access resource configured by the network device needs to meet the bandwidth capability of the second type of Redcap UE.

In a possible implementation, if the communication protocol stipulates that the first random access resource can be used by the second type of Redcap UE, then the second type of Redcap UE uses the first random access resource for random access, otherwise, the second type of The Redcap UE does not use the first random access resource to perform random access.

As shown in FIG. 4, an embodiment of the present disclosure provides an information transmission method, which is executed by a network side device, including:

Step 401: Send first indication information, wherein the first random access resource is determined by the second type of Redcap UE based on the first indication information whether it is used by the second type of Redcap UE.

Here, the predetermined manner may be that the base station indicates whether the first random access resource is used by the second type of Redcap UE through the first indication information.

Here, the first indication information may be determined by the network side device.

In a possible implementation manner, the network side device may determine the first indication information based on the configured first random access resource.

Exemplarily, if the first random access resource configured by the network side device satisfies the bandwidth capability of the second type of Redcap UE, the network side device may send first indication information to instruct the second type of Redcap UE to use the first random access resource for random access. access. If the first random access resource configured by the network side device does not meet the bandwidth capability of the second type of Redcap UE, the network side device can send the first indication information to instruct the second type of Redcap UE not to use the first random access resource for random access .

In a possible implementation manner, the network side device may configure the first random access resource based on the first indication information.

Exemplarily, if the network side device determines to send the first indication information to instruct the second type of Redcap UE to use the first random access resource for random access, then the network side device can configure the first random access resource that satisfies the bandwidth capability of the second type of Redcap UE. Random access to resources. If the network side device determines to send the first indication information to indicate that the second type of Redcap UE does not use the first random access resource for random access, then the network side device only considers the first random access that satisfies the bandwidth capability of the first type of Redcap UE resource.

In a possible implementation, the second type of Redcap UE determines according to the first indication information that the network side device has configured the first random access resource that can be used for the second type of Redcap UE, then the second type of Redcap UE can use the first random access resource. Access resources for random access, otherwise, do not use the first random access resource.

In a possible implementation manner, the second type of Redcap UE determines according to the first indication information that the first random access resource is not used by the second type of Redcap UE, then the second type of Redcap UE does not use the first random access resource.

In a possible implementation, the second type of Redcap UE determines according to the first indication information that the first random access resource is not for use by the second type of Redcap UE, even if the first random access resource meets the bandwidth capability of the second type of Redcap UE , the second type of Redcap UE does not use the first random access resource either.

In a possible implementation manner, the first indication information may be carried in a system message, or the first indication information may be carried in resource configuration information and sent to the UE.

In this way, the network side device can explicitly indicate whether the first random access resource is used by the second type of Redcap UE through the first indication information, and the second type of Redcap UE can determine whether the first random access resource can be used at least based on the first indication information Perform random access, reduce the uncertainty of the UE using the first random access resource, and improve the random access success rate of the second type of Redcap UE.

In an embodiment, the first random access resource includes: a first sub-random access resource and a second sub-random access resource, wherein the second sub-random access resource is provided by the second The Redcap-type UE determines whether to be used by the second-type Redcap UE based on a predetermined method.

The first sub-random access resource and the second sub-random access resource may be random access resources meeting the bandwidth capability of the first type of Redcap UE. The first sub-random access resource and the second sub-random access resource may be a subset of the first random access resource.

The second sub-random access resource may be a subset of the first random access resource configured by the network side device for the first type of Redcap UE for random access; the second sub-random access resource may satisfy the requirements of the second type Bandwidth capability of Redcap UE.

In a possible implementation manner, determining whether the first random access resource is used by the second type of Redcap UE based on a predetermined method includes the following item:

Whether the second sub-random access resource in the first random access resource is used by the second type of Redcap UE is indicated by the first indication information;

Whether the second sub-random access resource in the first random access resource is used by the second type of Redcap UE is specified by the communication protocol;

All resources in the first random access resource are indicated by the first indication information whether they are used by the second type of Redcap UE;

Whether all resources in the first random access resources are used by the second type of Redcap UE is specified by the communication protocol.

In a possible embodiment, if the network side device configures the second sub-random access resource, and the first indication information indicates or the communication protocol stipulates that the second sub-random access resource is used by the second type of Redcap UE, then the second The Redcap-like UE uses the second sub-random access resource.

In a possible embodiment, if the network side device does not configure the second sub-random access resource, and the network side device does not indicate or the communication protocol does not stipulate that the second sub-random access resource is used by the second type of Redcap UE, then, The second type of Redcap UE can behave according to the agreement (that is, based on a predetermined method), for example, it can use all resources in the first random access resources configured by the network side equipment for the first type of Redcap UE; or cannot use the network side equipment for the first random access resource. All resources in the first random access resources configured for the Redcap-like UE.

In a possible embodiment, the network-side device does not configure the second sub-random access resources of the subset, but the network-side device sends an indication (such as the first indication information) that the subset of random access resources can be shared, then the first type of users follow the first The indication information uses all RACH random access resources configured by the network side device for the second type of users; or cannot use all the resources in the RACH random access resources configured by the network side device for the second type of users.

The second random access resources include at least one of the following items: random access resources for 4-step access; random access resources for two-step access.

In a possible implementation manner, the second random access resource includes the transmission resource of msgA in the two-step access.

The resource configuration information of the second random access resource may be identified by the network side and broadcast to the UE. The identification information that may be carried in the resource configuration information of the second random access resource may indicate that the second random access resource indicated by the resource configuration information is used for the second type of Redcap UE.

The network side equipment may include at least one of the following: core network equipment; access network equipment (such as a base station).

The UE may include the second type of Redcap UE. The UE may also be another type of UE than the second type of RedCap UE.

The first type of RedCap UE may be the Redcap UE introduced by the 3GPP standard 17.

In a possible implementation manner, the data transmission bandwidth of the first type of RedCap UE is less than or equal to 20 MHz. For example, the data transmission bandwidth of the first type of RedCap UE can be up to 20MHz.

The second type of RedCap UE may be the eRedcap UE introduced by the 3GPP standard 18.

In a possible implementation manner, the data transmission bandwidth of the second type of RedCap UE is less than or equal to 5 MHz. For example, the downlink data transmission bandwidth of the second type of RedCap UE may be 20 MHz, but the uplink data transmission bandwidth may be up to 5 MHz.

The network side device may configure the first random access resource and determine resource configuration information before the UE performs random access.

Since the data transmission bandwidth of the first type of RedCap UE is less than 20 MHz, the data transmission bandwidth of the second type of Redcap UE is covered. Therefore, if the configured transmission bandwidth of the first random access resource configured for the first type of Redcap UE meets the requirements of the second type of Redcap UE, it can also be used by the second type of Redcap UE.

If the first random access resource cannot be used by the second type of Redcap UE, then the network device configures the first random access resource to ignore the bandwidth capability of the second type of Redcap UE (that is, the data transmission bandwidth is less than or equal to 5MHz), and only configures The first random access resource that can satisfy the bandwidth capability of the first type of Redcap UE (that is, the data transmission bandwidth is less than or equal to 5 MHz).

The second type of Redcap UE may determine whether to use the first random access resource to perform random access based on a predetermined method.

The network side device may send resource configuration information to the UE before the UE performs random access (including 4-step access or 2-step access).
