Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

The technical solution of the present invention can be applied to various communication systems, such as: Long Term Evolution (LTE)/Long Term Evolution-advanced (LTE-A) system, New Radio (NR) system wait.

Terminal equipment (User Equipment, UE), which can also be called mobile terminal (Mobile Terminal), mobile user equipment, etc., can communicate with one or more core networks via a wireless access network (for example, Radio Access Network, RAN) , the user equipment can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which is connected to The radio access network exchanges speech and/or data.

Network equipment is a device deployed in wireless access network equipment to provide wireless communication functions for terminal equipment. The network equipment can be, for example, a base station. The base station can be an evolved base station (eNB or e-NodeB, evolutionaryNode B) in LTE. and 5G base stations (gNB).

The technical solutions provided by various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

It should be noted that, first, the network device configures a PUCCH resource set for the UE. One or more resources in the resource set are then indicated through DCI for transmitting UCI information corresponding to one or more priorities. In the embodiment of the present invention, the conflict between one PUCCH resource and another PUCCH resource in the time domain can be understood as: there is an overlap between one PUCCH resource and another PUCCH resource in the time domain. The service priority corresponding to UCI can also be understood as the transmission priority of UCI.

Figure 1 shows an information transmission method according to an embodiment of the present application. The method shown in Figure 1 can be performed by a network device. As shown in Figure 1, methods include:

S110. Send the first downlink control information DCI, where the first DCI indicates the first physical uplink control channel PUCCH resource used to transmit the first uplink control information UCI, where the first UCI corresponds to the first service priority.

S120. Send a second DCI. The second DCI indicates N second PUCCH resources. The target second PUCCH resource among the N second PUCCH resources is used to transmit the second UCI. The second PUCCH resources except N-1 second PUCCH resources outside the target second PUCCH resource are used to transmit the first UCI, the N second PUCCH resources do not conflict in the time domain, and the second UCI corresponds to the second service Priority, N is a positive integer greater than or equal to 2.

Optionally, in some embodiments, the first service priority is lower than the second service priority. In this case, S110 and S120 can be understood as: the network device uses the first downlink control information (Downlink Control Information, DCI) to instruct the terminal device to transmit the first uplink control information (Uplink Control Information) corresponding to the low service priority. , UCI) first PUCCH resource, and indicates to the terminal device N second PUCCH resources that do not conflict in the time domain through the second DCI. One of the N second PUCCH resources is used to transmit the corresponding high service priority. second UCI, and one of the N-1 second PUCCH resources among the N second PUCCH resources except the second PUCCH used to transmit the second UCI is used to transmit the first UCI. The first UCI here may be, for example, the UCI of the eMBB service, and the second UCI is the UCI of the URLLC service.

That is to say, a new PUCCH resource indication method can be defined in the DCI indicating the PUCCH resource corresponding to the UCI with high service priority, so that the DCI indicates N PUCCH resources that do not conflict in the time domain, and one PUCCH resource is used for transmission Corresponding to UCI with high service priority, the other N-1 PUCCH resources are used to transmit UCI corresponding to low service priority.

Optionally, in some embodiments, the second UCI includes Hybrid Automatic Repeat Request (HARQ) feedback information. For example, the second UCI includes HARQ-ACK information.

The indication of the PUCCH resource may be indicated through the PUCCH resource indication field of the DCI. For example, for the second DCI, one state of the PUCCH resource indication field may indicate N resources, and different states may indicate different N resources.

S130: If the first PUCCH resource conflicts with the target second PUCCH resource in the time domain, receive the first UCI through one of the N-1 second PUCCH resources, and The second UCI is received through the target second PUCCH resource.

Optionally, in S130, the target second PUCCH resource is the first PUCCH resource among the N second PUCCH resources indicated by the PUCCH resource indication field. When the first PUCCH resource and the target second PUCCH resource are in the time domain, When there is a conflict, the first UCI is received through a PUCCH resource adjacent to the first PUCCH resource.

For example, as shown in Figure 2, assuming that the second service priority is a high service priority and the first service priority is a low service priority, the first UCI includes HARQ-ACK and channel state information. (Channel State Information, CSI), the second UCI includes HARQ-ACK and CSI as an example. If the bearer indicated by the second DCI corresponds to the PUCCH resource 1 of HARQ-ACK and CSI with high business priority (the black filled part in Figure 2) and the bearer indicated by the first DCI corresponds to HARQ-ACK and CSI with low business priority When the PUCCH resources (the part filled with slashes in Figure 2) conflict in the time domain, the terminal equipment will use the PUCCH resource 2 (the dotted box part in Figure 2) that carries the UCI corresponding to the low service priority indicated by the second DCI. ) to transmit HARQ-ACK and CSI corresponding to low service priority, that is, the terminal device will respectively transmit UCI corresponding to high service priority and UCI corresponding to low service priority on PUCCH resources that do not conflict in two time domains. Therefore, the transmission requirements of UCI corresponding to high business priority can be ensured, and the transmission of UCI corresponding to low business priority can be realized, thereby avoiding the problem of low resource utilization efficiency caused by discarding UCI corresponding to low business priority.

Further, if the PUCCHs used to transmit multiple UCIs corresponding to the same service priority in a time unit (for example, a slot or a subslot) conflict in the time domain, and the resources are allowed Multiplexing, multiple UCIs corresponding to the same service priority can reuse the PUCCH resources used to transmit the HARQ-ACK of the service priority for transmission. For example, if the PUCCH resources used to carry HARQ-ACK, CSI and scheduling request (SchedulingRequest, SR) corresponding to the same service priority conflict in the time domain, then the CSI and SR are multiplexed into the PUCCH carrying HARQ-ACK, or Say, the PUCCH resource used to carry HARQ-ACK is used to carry HARQ-ACK, CSI and SR.

For example, as shown in Figure 3, there is a conflict in the time domain between the PUCCH resources used to transmit HARQ-ACK corresponding to high service priority and the PUCCH resources used to transmit CSI corresponding to high service priority, then The PUCCH resources used to transmit HARQ-ACK corresponding to high service priority are multiplexed to transmit CSI corresponding to high service priority. Similarly, if the PUCCH resources used to transmit HAR-ACK corresponding to low service priority conflict with the PUCCH resources used to transmit CSI corresponding to low service priority in the time domain, then the PUCCH resources used to transmit HAR-ACK corresponding to low service priority are multiplexed. The PUCCH resource transmission of HARQ-ACK corresponds to CSI with low service priority.

Normally, physical layer signaling or parameters can distinguish the service priorities corresponding to different UCIs. The method shown in Figure 1 also includes: according to the first service priority corresponding to the first UCI carried by the first PUCCH resource and the target second The second service priority corresponding to the second UCI carried by the PUCCH resource determines the physical layer signaling or parameters.

For example, assuming that the first service priority corresponding to the first UCI is a low service priority and the second service priority corresponding to the second UCI is a high service priority, the physical layer signaling or parameters determined by the network device may be Yes: the second DCI is DCI in a specific DCI format (or size), or the second DCI is scrambled using a specific RadioNetwork Tempory Identity (RNTI) (for example, MCS-C-RNTI), or the second DCI The modulation and coding scheme (Modulation and Coding Scheme, MCS) configured in DCI adopts the MCS table with low spectral efficiency (MCS table index 3); the first DCI is DCI in other DCI formats except the above-mentioned specific DCI format, or the first DCI Scrambling is performed using RNTI other than the above specific RNTI, or the MCS configured in the first DCI does not use a low-frequency MCS table.

Figure 4 is an information transmission method according to another embodiment of the present invention. The method shown in Figure 4 is executed by a network device. As shown in Figure 4, the method includes:

S210. Send the first downlink control information DCI, which indicates the N first physical uplink control channel PUCCH resources used to transmit the first uplink control information UCI, where the first UCI corresponds to the first service priority, N is a positive integer greater than or equal to 2.

S220. Send a second DCI indicating a second PUCCH resource used to transmit the second UCI, and the second UCI corresponds to the second service priority.

Optionally, in some embodiments, the first service priority is lower than the second service priority. In this case, S210 and S220 can be understood as: the network device indicates to the terminal device, through the first DCI, N first PUCCH resources for transmitting the first UCI corresponding to the low service priority, and indicates to the terminal device, through the second DCI, one second PUCCH resource.

It can be understood that the N first PUCCH resources indicated by the network device to the terminal device through the first DCI do not conflict in the time domain. At least one first PUCCH resource among the N first PUCCH resources does not conflict with the second PUCCH resource in the time domain. Or the N first PUCCH resources and the second PUCCH resources all conflict in the time domain.

That is to say, a new PUCCH resource indication method can be defined in the DCI indicating the PUCCH resource corresponding to the UCI with low service priority, so that the DCI indicates N PUCCH resources that do not conflict in the time domain, and all of these N PUCCH resources can Used to transmit UCI corresponding to low business priority.

Optionally, in some embodiments, the first UCI includes HARQ feedback information. For example, the first UCI includes HARQ-ACK information.

S230, if there is a target first PUCCH resource among the N first PUCCH resources, receive the first UCI through the target first PUCCH resource, and receive the second UCI through the second PUCCH resource, Among the N first PUCCH resources, the first PUCCH resource before the target first PUCCH resource in the time domain conflicts with the second PUCCH resource in the time domain, and the target first PUCCH resource conflicts with the second PUCCH resource in the time domain. The second PUCCH resources do not conflict in the time domain.

That is to say, when the terminal device determines N first PUCCH resources indicated by the first DCI and one second PUCCH resource indicated by the second DCI, it determines whether there is a second PUCCH resource among the N first PUCCH resources. The first PUCCH resource whose resources do not conflict in the time domain. If there is a first PUCCH resource that does not conflict with the second PUCCH resource in the time domain, the first UCI is sent on the first PUCCH resource, and the first UCI is sent on the second PUCCH resource. A second UCI is sent on the resource.

Optionally, the terminal device may determine whether the first PUCCH resource conflicts with the second PUCCH resource in the time domain starting from the first first PUCCH resource indicated by the PUCCH resource indication field in the DCI. If the first first PUCCH resource conflicts with the second PUCCH resource, If the second PUCCH resource conflicts in the time domain, then continue to determine whether the second first PUCCH resource conflicts with the second PUCCH resource in the time domain. In this way, until it is found that there is no conflict with the second PUCCH resource in the time domain. of the first PUCCH resources or determine that the N first PUCCH resources and the second PUCCH resources all conflict in the time domain. If a first PUCCH resource that does not conflict with the second PUCCH resource in the time domain can be found, the first UCI is sent on the first PUCCH resource, and the second UCI is sent on the second PUCCH resource. Correspondingly, the network device receives the first UCI on the first PUCCH resource and receives the second UCI on the second PUCCH resource. If the first first PUCCH resource and the second PUCCH resource do not conflict in the time domain, the terminal device sends the first UCI through the first first PUCCH resource, and sends the second UCI through the second PUCCH resource. Correspondingly, the network device receives the first UCI on the first PUCCH resource and receives the second UCI on the second PUCCH resource.

For example, as shown in Figure 5, the network device indicates 2 PUCCH resources for carrying UCI (HARQ-ACK) corresponding to low service priority to the terminal device through DCI, and indicates 1 PUCCH resource to the terminal device through DCI. The first PUCCH resource is used to carry UCI corresponding to high business priority, and the first PUCCH resource used to carry UCI corresponding to low business priority is in the time domain with the PUCCH resource used to carry UCI corresponding to high business priority. If there is a conflict, the terminal device will carry the UCI corresponding to the low service priority on the second PUCCH resource used to carry the UCI corresponding to the low service priority.

Optionally, in some embodiments, the method shown in Figure 4 further includes: if the target first PUCCH resource does not exist among the N first PUCCH resources, receiving the The second UCI.

That is to say, if the N first PUCCH resources all conflict with the second PUCCH resources in the time domain, the terminal device only sends the second UCI on the second PUCCH resource and discards the first UCI. In this case, if the first service priority is lower than the second service priority, the terminal device only sends the UCI corresponding to the high service priority and discards the UCI corresponding to the low service priority. This ensures the transmission requirements of high-priority services.

Generally, physical layer signaling or parameters can distinguish the service priorities corresponding to different UCIs. The method shown in Figure 4 also includes: determining the physical layer signaling or parameters based on the first service priority corresponding to the first UCI carried by the target first PUCCH resource and the second service priority corresponding to the second UCI carried by the second PUCCH resource.

For example, assuming that the first service priority corresponding to the first UCI is a low service priority and the second service priority corresponding to the second UCI is a high service priority, the physical layer signaling or parameters determined by the network device may be Yes: the second DCI is DCI in a specific DCI format (or size), or the second DCI is scrambled using a specific RadioNetwork Tempory Identity (RNTI) (for example, MCS-C-RNTI), or the second DCI The modulation and coding scheme (Modulation and Coding Scheme, MCS) configured in DCI adopts the MCS table with low spectral efficiency (MCS table index 3); the first DCI is DCI in other DCI formats except the above-mentioned specific DCI format, or the first DCI Scrambling is performed using RNTI other than the above specific RNTI, or the MCS configured in the first DCI does not use a low-frequency MCS table.

Figure 6 is an information transmission method according to yet another embodiment of the present invention. The method shown in Figure 6 is executed by a network device. As shown in Figure 6, the method includes:

S310. Send the first downlink control information DCI. The first DCI indicates the first physical uplink control channel PUCCH resource used to transmit the first uplink control information UCI. The first UCI corresponds to the first service priority;

S320. Send the second DCI, where the second DCI indicates the second PUCCH resource;

S330: If the first PUCCH resource and the second PUCCH resource conflict in the time domain, receive the first UCI and the second UCI through the second PUCCH resource, and the second UCI corresponds to the second service Priority; if the first PUCCH resource and the second PUCCH resource do not conflict in the time domain, receive the first UCI through the first PUCCH resource and receive the third UCI through the second PUCCH resource. 2UCI.

Optionally, in some embodiments, the first service priority is lower than the second service priority. In this case, S310 and S320 can be understood as: the network device indicates to the terminal device through the first DCI the first PUCCH resource for transmitting the first UCI corresponding to the low service priority, and indicates to the terminal device through the second DCI Second PUCCH resource. When the first PUCCH resource and the second PUCCH resource conflict in the time domain, the first UCI and the second UCI are multiplexed on the second PUCCH resource for transmission. When the first PUCCH resource and the second PUCCH resource do not conflict in the time domain, the first UCI is transmitted on the first PUCCH resource, and the second UCI is transmitted on the second PUCCH resource. Therefore, the problem of low resource utilization caused by directly discarding the UCI corresponding to the low-priority service can be avoided.

As an example, when the first service priority is lower than the second service priority, an indication field may be added to the second DCI or higher layer signaling to indicate whether the second PUCCH resource is allowed to bear the corresponding low service priority. UCI. For example, add a 1-bit UCI bearer indication field to the second DCI. The value of the indication field is "1", which means that UCI with low service priority is allowed to be carried. The value of the indication field is "0", which means that the UCI with low service priority is not allowed to be carried. level UCI.

Optionally, in some embodiments, the second UCI includes hybrid automatic repeat request HARQ feedback information. For example, the second UCI includes HARQ-ACK information. In this case, if the first service priority is lower than the second service priority, a DCI indicating a PUCCH resource that carries a UCI corresponding to a high service priority that can be used to carry a different service priority (low service priority) may be indicated. Priority and high service priority) PUCCH resources of multiple UCIs.

Normally, physical layer signaling or parameters can distinguish the service priorities corresponding to different UCIs. The method shown in Figure 6 also includes: according to the first service corresponding to the first UCI carried by the first PUCCH resource The priority and the second service priority corresponding to the second UCI carried by the second PUCCH resource determine physical layer signaling or parameters.

For example, assuming that the first service priority corresponding to the first UCI is a low service priority and the second service priority corresponding to the second UCI is a high service priority, the physical layer signaling or parameters determined by the network device may be Yes: the second DCI is DCI in a specific DCI format (or size), or the second DCI is scrambled using a specific RadioNetwork Tempory Identity (RNTI) (for example, MCS-C-RNTI), or the second DCI The modulation and coding scheme (Modulation and Coding Scheme, MCS) configured in DCI adopts the MCS table with low spectral efficiency (MCS table index 3); the first DCI is DCI in other DCI formats except the above-mentioned specific DCI format, or the first DCI Scrambling is performed using RNTI other than the above specific RNTI, or the MCS configured in the first DCI does not use a low-frequency MCS table.
