The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

Fig. 1 is a schematic structural diagram of a communication system to which the embodiment of the present application is applicable. The communication system may be a 5G communication system, and as shown in fig. 1, the communication system may include a network-side device 100 and a terminal device 200.

The network side device 100 is a device for providing a wireless communication function for a terminal device, and includes but is not limited to: a gbb, an RNC (radio network controller), an NB (node B), a BSC (base station controller), a BTS (base transceiver station), an HNB (e.g., home evolved node B or home node B), a BBU (base band Unit), a TRP (transmission and reception point), a TP (transmission point), a mobile switching center, and the like in 5G. The network-side device 100 may also be a device that provides a wireless communication function for the terminal device in other communication systems that may appear in the future.

In the following specific embodiment, the Network side device 100 is taken as a base station for example, and the base station is taken as a Radio Access Network (RAN) node and may include a gNB providing a Radio Network user plane and control plane protocol and functions for a 5G Network.

The terminal device 200 is a device with a wireless communication function, and can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal may be a mobile phone, a pad, a computer with wireless transceiving function, a VR (virtual reality) terminal, an AR (augmented reality) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.; but also various forms of UE (User Equipment), MS (mobile station), etc.

Terminal device 200 may provide voice and/or data connectivity to a user, have wireless connectivity, may be connected to a wireless modem, and the like. The terminal device 200 may communicate with one or more core networks via the network-side device 100.

In the process of communication between the network side device 100 and the terminal device 200, the data uplink supports two physical channel resources with different priorities. However, for the same terminal device, in order to avoid an excessive PAPR (Peak to Average Power Ratio), simultaneous transmission of multiple PUCCH (Physical Uplink Control Channel) resources is not supported, and simultaneous transmission of PUCCH resources and PUSCH (Physical Uplink Shared Channel) resources is also not supported. Currently, when a high-priority physical channel resource and a low-priority physical channel resource overlap in a time domain, a terminal device discards the low-priority physical channel resource and transmits only the high-priority physical channel resource. For example, when a high-priority PUCCH resource and a low-priority PUCCH resource overlap in the time domain, the terminal device may discard the low-priority PUCCH resource and transmit only the high-priority PUCCH resource.

In order to reduce the influence of discarding the physical channel resources with low priority on data transmission under the condition that the physical channel resources with different priorities overlap in the time domain, a solution that can multiplex the physical channel resources with different priorities is needed. However, when UCI (Uplink Control Information) with different priorities are multiplexed on the same resource for transmission, no clear transmission scheme exists at present. For example, when HARQ-ACKs (Hybrid Automatic Repeat request-acknowledgement) of different priorities are multiplexed on the same PUCCH resource, or when HARQ-ACKs of different priorities are multiplexed on the same PUSCH resource, it is not clear whether independent coding or joint coding should be used.

In order to solve the above problem, embodiments of the present application provide a UCI multiplexing transmission method, a network side device, and a terminal device. When resources corresponding to UCI to be transmitted with different priorities are overlapped in a time domain, the terminal device may determine a coding mode for each UCI to be transmitted based on a ratio of information lengths of the UCI to be transmitted with different priorities, code the UCI to be transmitted based on the determined coding mode, and transmit the coded UCI through the same resource. The network side equipment receives UCI to be decoded transmitted through the same resource, determines a coding mode aiming at the UCI based on the ratio of the information lengths of the UCI with different priorities contained in the UCI to be decoded, and decodes the UCI based on the determined coding mode to obtain data in the UCI. The coding mode may be joint coding or independent coding. Through the process, the multiplexing transmission of UCIs with different priorities on the same resource can be realized, so that the phenomenon that the physical channel resources with low priorities are discarded when physical channels with different priorities are overlapped in time domains is reduced.

Specifically, the UCI to be transmitted may include one or more of the following information: HARQ-ACK, CSI (Channel State Information), SR (Scheduling Request). Correspondingly, UCI of different priorities contained in UCI to be decoded may also include one or more of the following information: HARQ-ACK, CSI, SR.

The resources multiplexed on the same resource may be PUCCH resources of PUCCH format 2, format 3, or format 4, and/or PUSCH resources. The PUCCH format is a resource format specified by The 3rd Generation Partnership Project (3 GPP) protocol, and in The 3GPP 5G NR protocol, PUCCH resources have 5 formats, format 0, format 1, format 2, format 3, and format 4. The data transmitted on the PUCCH resources in format 0 and format 1 may be transmitted without being encoded, and the data transmitted on the PUCCH resources in format 2, format 3, and format 4 may be transmitted without being encoded.

As shown in fig. 2, the method executed by the terminal device 200 includes the following steps:

step S201, if resources corresponding to UCI to be transmitted of different priorities overlap in a time domain, determining a coding mode for the UCI to be transmitted based on a ratio of information lengths of the UCI to be transmitted of different priorities.

In an embodiment, the terminal device may determine, based on a ratio of bit numbers of the UCI to be transmitted of different priorities, a coding mode for each UCI to be transmitted. Specifically, a first ratio of the number of bits of the UCI to be transmitted with the high priority to the number of bits of the UCI to be transmitted with the low priority may be determined, and if the first ratio is greater than a first threshold, joint coding is determined for each UCI to be transmitted; if the first ratio is smaller than the first threshold value, determining to independently encode each UCI to be transmitted; and if the first ratio is equal to the first threshold value, determining to perform joint coding on each UCI to be transmitted. Or if the first ratio is greater than the first threshold, determining to perform joint coding on each UCI to be transmitted; if the first ratio is smaller than the first threshold value, determining to independently encode each UCI to be transmitted; and if the first ratio is equal to the first threshold value, determining to independently encode each UCI to be transmitted.

That is, if the first ratio is greater than or equal to the first threshold, determining to perform joint coding on each UCI to be transmitted; and if the first ratio is smaller than the first threshold value, determining to independently encode each UCI to be transmitted. Or if the first ratio is greater than the first threshold, determining to perform joint coding on each UCI to be transmitted; and if the first ratio is smaller than or equal to the first threshold value, determining to independently encode each UCI to be transmitted.

Wherein, the first threshold value is a predefined value or a value configured by a high-level signaling; the high layer signaling is RRC (Radio Resource Control) signaling or MAC CE (Medium access Control-Control element) signaling.

In another embodiment, the coding mode for each UCI to be transmitted may be determined based on a ratio of the number of coding bits of the UCI to be transmitted at different priorities. Specifically, the number of coded bits of the UCI to be transmitted with the high priority may be determined according to the number of bits of the UCI to be transmitted with the high priority and the code rate of the UCI to be transmitted with the high priority; determining the number of coded bits of the UCI to be transmitted with low priority according to the number of bits of the UCI to be transmitted with low priority and the code rate of the UCI to be transmitted with low priority; determining a second ratio of the number of the coding bits of the UCI to be transmitted with high priority to the number of the coding bits of the UCI to be transmitted with low priority; and determining the coding mode aiming at each UCI to be transmitted according to the second ratio.

If the second ratio is larger than a second threshold value, determining to perform joint coding on each UCI to be transmitted; if the second ratio is smaller than the second threshold value, determining to independently encode each UCI to be transmitted; and if the second ratio is equal to the second threshold value, determining to perform joint coding on each UCI to be transmitted. Or if the second ratio is greater than the second threshold, determining to perform joint coding on each UCI to be transmitted; if the second ratio is smaller than the second threshold value, determining to independently encode each UCI to be transmitted; and if the second ratio is equal to the second threshold value, determining to independently encode each UCI to be transmitted.

That is, if the second ratio is greater than or equal to the second threshold, determining to perform joint coding on each UCI to be transmitted; and if the second ratio is smaller than the second threshold value, determining to independently encode each UCI to be transmitted. Or if the second ratio is greater than the second threshold, determining to perform joint coding on each UCI to be transmitted; and if the second ratio is less than or equal to the second threshold value, determining that independent coding is carried out on each UCI to be transmitted.

For example, it is assumed that the number of bits of the UCI to be transmitted with the high priority is divided by the code rate of the UCI to be transmitted with the high priority to obtain the number of coded bits a, and the number of bits of the UCI to be transmitted with the low priority is divided by the code rate of the UCI to be transmitted with the low priority to obtain the number of coded bits B.

If the ratio of A to B is larger than a second threshold value, determining that each UCI to be transmitted is multiplexed on the same resource and uses joint coding;

if the ratio of A to B is smaller than a second threshold value, determining that each UCI to be transmitted is multiplexed on the same resource and uses independent codes;

and if the ratio of the A to the B is equal to the second threshold value, determining that each UCI multiplex to be transmitted uses joint coding on the same resource, or determining that each UCI multiplex to be transmitted uses independent coding on the same resource.

The second threshold value is a predefined value or a value configured by a high-level signaling; the high-layer signaling is RRC signaling or MAC CE signaling.

Step S202, based on the determined coding mode, the UCI to be transmitted is coded, and the coded UCI is transmitted through the same resource.

The same resource may be a high-priority physical channel resource or a low-priority physical channel resource.

By the method, the terminal equipment can definitely determine whether to use independent coding or joint coding for each UCI to be transmitted based on the ratio of the information lengths of the UCIs to be transmitted with different priorities, that is, the terminal equipment can determine the coding mode used when the UCIs with different priorities are multiplexed on the same resource based on the ratio of the information lengths of the UCIs with different priorities, so that the UCIs to be transmitted can be coded based on the determined coding mode, and the UCIs to be transmitted with different priorities are multiplexed and transmitted on the same resource.

In some embodiments, before determining the coding mode for the UCI to be transmitted based on the ratio of the information lengths of the UCI to be transmitted at different priorities, the method for multiplexing and transmitting the UCI provided in this embodiment of the present application may further include:

when the information length of the UCI to be transmitted with high priority is greater than a first set length and the information length of the UCI to be transmitted with low priority is greater than a second set length, executing a step of determining the coding mode aiming at each UCI to be transmitted based on the ratio of the information lengths of the UCI to be transmitted with different priorities; and if the information length of the UCI to be transmitted with the high priority is less than or equal to a first set length, or the information length of the UCI to be transmitted with the low priority is less than or equal to a second set length, determining that joint coding is carried out on each UCI to be transmitted.

That is, if the information length of the UCI to be transmitted with the high priority is less than or equal to the first set length and the information length of the UCI to be transmitted with the low priority is greater than the second set length, it may be determined that joint coding is performed on each UCI to be transmitted. If the information length of the UCI to be transmitted with high priority is greater than the first set length, and the information length of the UCI to be transmitted with low priority is less than or equal to the second set length, the UCI to be transmitted with low priority can also be determined to be subjected to joint coding. If the information length of the UCI to be transmitted with the high priority is less than or equal to the first set length and the information length of the UCI to be transmitted with the low priority is also less than or equal to the second set length, it may also be determined that joint coding is performed on each UCI to be transmitted.

The first set length and the second set length are predefined values or values configured by a high-level signaling; the high-level signaling is RRC signaling or MAC CE signaling. The first set length and the second set length are positive integers.

For example, if the number of UCI bits to be transmitted with high priority is greater than a predefined number of bits X and the number of UCI bits to be transmitted with low priority is greater than a predefined number of bits Y, determining a coding scheme used when UCI to be transmitted with different priorities are multiplexed on the same resource based on the ratio of the lengths of UCI to be transmitted with different priorities; otherwise a joint coding scheme is always used. The bit number X and the bit number Y are predefined or high-level configured positive integers.

In some embodiments, it may be determined that resources corresponding to UCI to be transmitted with different priorities overlap in a time domain by: and if the resources corresponding to the UCIs to be transmitted with different priorities are overlapped on the time domain, or the resources corresponding to the UCIs to be transmitted with different priorities are all overlapped with the third resource on the time domain, determining that the resources corresponding to the UCIs to be transmitted with different priorities are overlapped on the time domain. If the resources corresponding to the UCI to be transmitted with different priorities are overlapped in the time domain, the coding mode for each UCI to be transmitted can be determined based on the ratio of the information lengths of the UCI to be transmitted with different priorities, each UCI to be transmitted is coded based on the determined coding mode, and the coded UCI is transmitted through the resource corresponding to the UCI to be transmitted with high priority.

For more convenient understanding, the multiplexing transmission method of UCI performed by the terminal device is explained below by several specific embodiments.

Example one

As shown in fig. 3, a PUCCH resource carrying HP (High Priority) HARQ-ACK information and a PUCCH resource carrying LP (Low Priority) HARQ-ACK information are overlapped in a time domain, and a threshold value selected by a predefined coding scheme is 2.

Case 1: and assuming that the bit number of the HP HARQ-ACK information is 3 and the bit number of the LP HARQ-ACK information is 9, the ratio of the bit number of the HP HARQ-ACK information to the bit number of the LP HARQ-ACK information is 1/3 and is smaller than a threshold value 2, and then the independent coding mode is determined to be used for multiplexing.

Case 2: and assuming that the bit number of the HP HARQ-ACK information is 9 and the bit number of the LP HARQ-ACK information is 3, the ratio of the bit number of the HP HARQ-ACK information to the bit number of the LP HARQ-ACK information is 3, and the ratio is larger than a threshold value 2, and then the multiplexing is carried out by using a joint coding mode.

Case 3: and assuming that the bit number of the HP HARQ-ACK information is 6 and the bit number of the LP HARQ-ACK information is 3, the ratio of the bit number of the HP HARQ-ACK information to the bit number of the LP HARQ-ACK information is 2 and is equal to a threshold value of 2, and then the joint coding mode is determined to be used for multiplexing.

In this embodiment, the example of selecting the joint coding scheme for multiplexing is described, and in other embodiments, in case 3, the independent coding scheme may be selected for multiplexing.

And based on the determined coding mode, after each UCI to be transmitted is coded, the terminal equipment can transmit the coded UCI through the HP PUCCH resources. The HP PUCCH resource is a PUCCH resource corresponding to the HP HARQ-ACK information, or the HP HARQ-ACK information is loaded through the PUCCH resource.

Example two

As shown in fig. 3, a PUCCH resource carrying HP HARQ-ACK information (i.e. HP PUCCH) and a PUCCH resource carrying LP HARQ-ACK information (i.e. LP PUCCH) overlap in the time domain, and it is assumed that the threshold value selected by the RRC signaling configuration predefined coding scheme is 1. The Slot in fig. 3 represents one Slot.

Case 1: assuming that the bit number of the HP HARQ-ACK information is 3 and the corresponding code rate is 0.2, the coding bit number of the HP HARQ-ACK information is 15. The bit number of the LP HARQ-ACK information is 9, and the corresponding code rate is 0.5, then the coding bit number of the LP HARQ-ACK information is 18. And the ratio of the coding bit number of the HP HARQ-ACK information to the coding bit number of the LP HARQ-ACK information is 5/6, and if the ratio is less than a threshold value 1, the multiplexing is carried out by using an independent coding mode.

Case 2: assuming that the bit number of the HP HARQ-ACK information is 5 and the corresponding code rate is 0.2, the encoding bit number of the HP HARQ-ACK is 25. The bit number of the LP HARQ-ACK information is 9, the corresponding code rate is 0.5, the coding bit number of the LP HARQ-ACK information is 18, the ratio of the coding bit number of the HP HARQ-ACK information to the coding bit number of the LP HARQ-ACK information is 25/18 and is larger than a threshold value 1, and then the multiplexing is carried out by using a joint coding mode.

Case 3: assuming that the bit number of the HP HARQ-ACK information is 2 and the corresponding code rate is 0.2, the coding bit number of the HP HARQ-ACK information is 10, the bit number of the LP HARQ-ACK information is 5 and the corresponding code rate is 0.5, the coding bit number of the LP HARQ-ACK information is 10, the ratio of the coding bit number of the HP HARQ-ACK information to the coding bit number of the LP HARQ-ACK information is 1 and equal to a threshold value 1, and then the multiplexing is determined by using a joint coding mode.

EXAMPLE III

As shown in fig. 3, a PUCCH resource carrying HP HARQ-ACK information and a PUCCH resource carrying LP HARQ-ACK information overlap in a time domain, a threshold value selected by a predefined coding scheme is 1, and both predefined X and Y values are 2, that is, only when the number of bits of HP HARQ-ACK information and LP HARQ-ACK information is greater than 2, a coding scheme is selected based on the threshold value 1, otherwise, a joint coding scheme is always used.

Case 1: and if the bit number of the HP HARQ-ACK information is 2 and the bit number of the LP HARQ-ACK information is 6, determining to use a joint coding mode for multiplexing because the bit number of the HP HARQ-ACK information is not more than 2.

Case 2: and assuming that the bit number of the HP HARQ-ACK information is 5 and the bit number of the LP HARQ-ACK information is 6, determining that the ratio of the bit number of the HP HARQ-ACK information to the bit number of the LP HARQ-ACK information is 5/6 and is less than a threshold value 1, and selecting to use an independent coding mode for multiplexing.

Case 3: and if the bit number of the HP HARQ-ACK information is 5 and the bit number of the LP HARQ-ACK information is 1, determining that the joint coding mode is used for multiplexing because the bit number of the LP HARQ-ACK information is not more than 2.

Case 4: and assuming that the bit number of the HP HARQ-ACK information is 4 and the bit number of the LP HARQ-ACK information is 2, determining that the ratio of the bit number of the HP HARQ-ACK information to the bit number of the LP HARQ-ACK information is 2, and selecting to use a joint coding mode for multiplexing if the ratio is greater than a threshold value 1.

After each UCI to be transmitted is encoded based on the determined encoding mode, the terminal device may transmit the encoded UCI through the HP PUCCH resource, as shown by an arrow in fig. 3. The HP PUCCH resource is a PUCCH resource corresponding to the HP HARQ-ACK information, or the PUCCH resource bearing the HP HARQ-ACK information.

As shown in fig. 4, a PUCCH resource (i.e. HP PUCCH) carrying HP HARQ-ACK information overlaps with an HP PUSCH resource in the time domain, and a PUCCH resource (i.e. LP PUCCH) carrying LP HARQ-ACK information also overlaps with the HP PUSCH resource in the time domain, assuming that the threshold value selected by the predefined coding scheme is 2. The Slot in fig. 4 represents one Slot.

Case 1: and assuming that the bit number of the HP HARQ-ACK information is 2 and the bit number of the LP HARQ-ACK information is 6, the ratio of the bit number of the HP HARQ-ACK information to the bit number of the LP HARQ-ACK information is 1/3 and is smaller than a threshold value 2, and then the independent coding mode is determined to be used for multiplexing.

Case 2: and assuming that the bit number of the HP HARQ-ACK information is 6 and the bit number of the LP HARQ-ACK information is 2, the ratio of the bit number of the HP HARQ-ACK information to the bit number of the LP HARQ-ACK information is 3, and the ratio is greater than a threshold value 2, and then the multiplexing is carried out by using a joint coding mode.

In this embodiment, the joint coding method is selected for multiplexing, but in other embodiments, in case 3, the independent coding method may be selected for multiplexing.

After encoding each UCI to be transmitted based on the determined encoding mode, the terminal device may transmit the encoded UCI through the HP PUSCH resource, as shown by an arrow in fig. 4.

The method executed by the network side device 100 is shown in fig. 5, and includes the following steps:

step S501, for the received UCI to be decoded, based on the ratio of the information lengths of the UCI with different priorities included in the UCI to be decoded, determining an encoding mode for the UCI.

The UCI to be decoded is an encoded UCI transmitted by the same resource. The coded UCI is obtained by determining a coding mode aiming at the UCI to be transmitted based on the ratio of the information lengths of the UCI to be transmitted with different priorities when the terminal equipment determines that resources corresponding to the UCI to be transmitted with different priorities are overlapped on a time domain, and coding the UCI to be transmitted based on the determined coding mode.

Taking the network side device 100 as a base station as an example, since the physical channel resource used by the terminal device and the information length of the UCI carried on the physical channel resource are scheduled by the base station, or the terminal device and the base station are determined according to a protocol, the base station may obtain the information lengths of the UCI with different priorities contained in the received UCI to be decoded, and determine the coding method for the UCI based on the ratio of the information lengths of the UCI with different priorities contained in the UCI to be decoded.

The specific process of determining the coding mode for the UCI by the base station is the same as the specific process of determining the coding mode for the UCI to be transmitted by the terminal device, and therefore, the above implementation can be referred to, and details are not repeated herein.

Step S502, decoding the UCI based on the determined coding mode to obtain data in the UCI.

The network side equipment adopts a method corresponding to the terminal equipment, and determines a coding mode aiming at the UCI based on the ratio of the information lengths of the UCIs with different priorities, so that the UCI transmitted on the same resource can be decoded based on the determined coding mode to obtain data in the UCI, and the phenomenon that the physical channel resources with low priorities are discarded when the physical channels with different priorities are overlapped in a time domain is reduced.

Exemplarily, in an embodiment, assuming that the number of bits of the UCI to be transmitted with the high priority is 6 and the number of bits of the UCI to be transmitted with the low priority is 3, a ratio of the number of bits of the UCI to be transmitted with the high priority to the number of bits of the UCI to be transmitted with the low priority is 2 and equal to a threshold 2, and the terminal device determines to encode the UCI to be transmitted by using a joint coding method and transmits the encoded UCI through the PUCCH resource with the high priority. The base station receives the UCI to be decoded transmitted through the PUCCH resource of the high priority, and determines that the ratio of the bit number of the UCI of the high priority to the bit number of the UCI of the low priority is 2, which is equal to the threshold value 2, that is, it is determined that the coding mode for the UCI is joint coding. And the base station decodes the UCI based on the determined coding mode to obtain data in the UCI.

In another embodiment, assuming that the number of bits of the UCI to be transmitted with the high priority is 6 and the number of bits of the UCI to be transmitted with the low priority is 3, the ratio of the number of bits of the UCI to be transmitted with the high priority to the number of bits of the UCI to be transmitted with the low priority is 2, which is equal to a threshold value 2, and the terminal device determines to encode the UCI to be transmitted by using an independent encoding method and transmits the encoded UCI through the PUCCH resource with the high priority. The base station receives the UCI to be decoded transmitted through the PUCCH resource of the high priority, and determines that the ratio of the bit number of the UCI of the high priority to the bit number of the UCI of the low priority is 2, which is equal to the threshold value 2, that is, it is determined that the coding mode for the UCI is independent coding. And the base station decodes the UCI based on the determined coding mode to obtain data in the UCI.
