[0002] At present, mobile communication networks have entered the era of 5G (Fifth Generation) mobile communication technology. In the 5G NR (New RAT) system, the data uplink supports two physical channel resources with different priorities. When the high-priority physical channel resources and the low-priority physical channel resources overlap in the time domain, the terminal device discards the low-priority physical channel resources and only transmits the high-priority physical channel resources.

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

[0083] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0084] Figure 1 Schematic diagram of the structure of the communication system applicable to the embodiment of the present application. The communication system may be a 5G communication system, such as Figure 1 As shown, the communication system may include a network side device 100 and a terminal device 200.

[0085] The network-side device 100 is a device that provides wireless communication functions for terminal devices, including but not limited to: gNB, RNC (radio network controller), NB (node ​​B), BSC (base station controller), BTS (base transceiver station), HNB (for example, home evolved node B, or home node B), BBU (Base Band Unit), TRP (transmitting and receiving point), TP (transmitting point), mobile switching center, etc. in 5G. The network-side device 100 may also be a device that provides wireless communication functions for terminal devices in other communication systems that may appear in the future.

[0086] In the specific embodiments below, the network-side device 100 is described as a base station. The base station, as a radio access network (RAN) node, may include a gNB that provides wireless network user plane and control plane protocols and functions for the 5G network.

[0087] The terminal device 200 is a device with wireless communication capabilities and can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water (such as ships); and can also be deployed in the air (such as airplanes, balloons, and satellites). The terminal can be a mobile phone, a pad (tablet), a computer with wireless transceiver capabilities, 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. It can also be various forms of UE (User Equipment), MS (Mobile Station), etc.

[0088] The terminal device 200 can provide voice and / or data connectivity to the user, has a wireless connection function, and can be connected to a wireless modem, etc. The terminal device 200 can communicate with one or more core networks via the network side device 100 .

[0089] During the 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 excessive PAPR (Peak to Average Power Ratio), the simultaneous transmission of multiple PUCCH (Physical Uplink Control Channel) resources is not supported, nor is the simultaneous transmission of PUCCH resources and PUSCH (Physical Uplink Shared Channel) resources supported. Currently, when high-priority physical channel resources and low-priority physical channel resources overlap in the time domain, the terminal device discards the low-priority physical channel resources and only transmits high-priority physical channel resources. For example, when high-priority PUCCH resources and low-priority PUCCH resources overlap in the time domain, the terminal device will discard the low-priority PUCCH resources and only transmit high-priority PUCCH resources.

[0090] In order to reduce the impact of discarding low-priority physical channel resources on data transmission when physical channel resources of different priorities overlap in the time domain, a solution is needed to multiplex physical channel resources of different priorities for transmission. However, there is currently no clear transmission solution for when UCI (Uplink Control Information) of different priorities is multiplexed on the same resource for transmission. For example, when HARQ-ACK (Hybrid Automatic Repeat request-ACKnowledgment) of different priorities is multiplexed on the same PUCCH resource, or when HARQ-ACK of different priorities is multiplexed on the same PUSCH resource, it is unclear whether independent coding or joint coding should be used.

[0091] In response to the above problems, an embodiment of the present application provides a multiplexing transmission method of UCI, a network side device, and a terminal device. Among them, when the resources corresponding to the UCI to be transmitted of different priorities overlap in the time domain, the terminal device can determine the encoding method for each UCI to be transmitted based on the ratio of the information lengths of the UCI to be transmitted of different priorities, encode the UCI to be transmitted based on the determined encoding method, and transmit the encoded UCI through the same resource. The network side device receives the UCI to be decoded transmitted through the same resource, determines the encoding method for the UCI based on the ratio of the information lengths of the UCIs of different priorities contained in the UCI to be decoded, decodes the UCI based on the determined encoding method, and obtains the data in the UCI. Among them, the encoding method can be joint encoding or independent encoding. Through the above process, the multiplexing transmission of UCIs of different priorities on the same resource can be achieved, thereby reducing the phenomenon of discarding low-priority physical channel resources when physical channels of different priorities overlap in the time domain.

[0092] Specifically, the UCI to be transmitted may include one or more of the following information: HARQ-ACK, CSI (Channel State Information), and SR (Scheduling Request). Correspondingly, the UCI of different priorities included in the UCI to be decoded may also include one or more of the following information: HARQ-ACK, CSI, and SR.

[0093] The resources multiplexed on the same resource can 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 3GPP (The 3rd Generation Partnership Project) protocol. In the 3GPP 5G NR protocol, PUCCH resources have five formats: format 0, format 1, format 2, format 3, and format 4. Among them, data transmitted on PUCCH resources of format 0 and format 1 can be transmitted without encoding, while data transmitted on PUCCH resources of format 2, format 3, and format 4 requires encoding before transmission.

[0094] The method executed by the terminal device 200 is as follows: Figure 2 As shown, the following steps are included:

[0095] Step S201 : If resources corresponding to UCI to be transmitted of different priorities overlap in the time domain, a coding scheme for the UCI to be transmitted is determined based on a ratio of information lengths of the UCI to be transmitted of different priorities.

[0096] In one embodiment, the terminal device may determine the encoding method for each UCI to be transmitted based on the ratio of the number of bits of UCI to be transmitted of different priorities. Specifically, a first ratio of the number of bits of high-priority UCI to be transmitted to the number of bits of low-priority UCI to be transmitted may be determined. If the first ratio is greater than a first threshold value, it is determined that each UCI to be transmitted is jointly encoded; if the first ratio is less than the first threshold value, it is determined that each UCI to be transmitted is independently encoded; if the first ratio is equal to the first threshold value, it is determined that each UCI to be transmitted is jointly encoded. Alternatively, if the first ratio is greater than the first threshold value, it is determined that each UCI to be transmitted is jointly encoded; if the first ratio is less than the first threshold value, it is determined that each UCI to be transmitted is independently encoded; if the first ratio is equal to the first threshold value, it is determined that each UCI to be transmitted is independently encoded.

[0097] That is, if the first ratio is greater than or equal to the first threshold, joint coding is performed for each UCI to be transmitted; if the first ratio is less than the first threshold, independent coding is performed for each UCI to be transmitted. Alternatively, if the first ratio is greater than the first threshold, joint coding is performed for each UCI to be transmitted; if the first ratio is less than or equal to the first threshold, independent coding is performed for each UCI to be transmitted.

[0098] The first threshold value is a predefined value or a value configured by high-layer signaling; the high-layer signaling is RRC (Radio Resource Control) signaling or MAC CE (Medium access control-control element) signaling.

[0099] In another embodiment, the encoding method for each UCI to be transmitted can be determined based on the ratio of the number of encoded bits of UCI to be transmitted with different priorities. Specifically, the number of encoded bits of the high-priority UCI to be transmitted can be determined based on the number of bits of the high-priority UCI to be transmitted and the code rate of the high-priority UCI to be transmitted; the number of encoded bits of the low-priority UCI to be transmitted can be determined based on the number of bits of the low-priority UCI to be transmitted and the code rate of the low-priority UCI to be transmitted; a second ratio of the number of encoded bits of the high-priority UCI to be transmitted to the number of encoded bits of the low-priority UCI to be transmitted can be determined; and based on the second ratio, the encoding method for each UCI to be transmitted can be determined.

[0100] If the second ratio is greater than a second threshold value, it is determined that joint coding is performed for each UCI to be transmitted; if the second ratio is less than the second threshold value, it is determined that independent coding is performed for each UCI to be transmitted; if the second ratio is equal to the second threshold value, it is determined that joint coding is performed for each UCI to be transmitted. Alternatively, if the second ratio is greater than the second threshold value, it is determined that joint coding is performed for each UCI to be transmitted; if the second ratio is less than the second threshold value, it is determined that independent coding is performed for each UCI to be transmitted; if the second ratio is equal to the second threshold value, it is determined that independent coding is performed for each UCI to be transmitted.

[0101] That is, if the second ratio is greater than or equal to the second threshold, joint coding is performed for each UCI to be transmitted; if the second ratio is less than the second threshold, independent coding is performed for each UCI to be transmitted. Alternatively, if the second ratio is greater than the second threshold, joint coding is performed for each UCI to be transmitted; if the second ratio is less than or equal to the second threshold, independent coding is performed for each UCI to be transmitted.

[0102] For example, assume that the number of bits of high-priority UCI to be transmitted is divided by the code rate of the high-priority UCI to be transmitted to obtain the coded bit number A, and the number of bits of low-priority UCI to be transmitted is divided by the code rate of the low-priority UCI to be transmitted to obtain the coded bit number B.

[0103] If the ratio of A to B is greater than the second threshold, it is determined that the UCIs to be transmitted are multiplexed on the same resource using joint coding;

[0104] If the ratio of A to B is less than the second threshold, it is determined that each UCI to be transmitted is multiplexed on the same resource and independently coded;

[0105] If the ratio of A to B is equal to the second threshold, it is determined that each UCI to be transmitted is multiplexed on the same resource using joint coding, or it is determined that each UCI to be transmitted is multiplexed on the same resource using independent coding.

[0106] The second threshold value is a predefined value or a value configured by high-layer signaling; the high-layer signaling is RRC signaling or MAC CE signaling.

[0107] Step S202: Encode the UCI to be transmitted based on the determined encoding method, and transmit the encoded UCI through the same resource.

[0108] The same resource may be a high-priority physical channel resource or a low-priority physical channel resource.

[0109] Through the above method, the terminal device can clearly determine whether to use independent coding or joint coding for each UCI to be transmitted based on the ratio of the information lengths of UCI to be transmitted with different priorities. That is to say, the terminal device can determine the encoding method to be used when UCIs of different priorities are multiplexed on the same resource based on the ratio of the information lengths of UCIs of different priorities, so that the UCI to be transmitted can be encoded based on the determined encoding method, and UCIs of different priorities to be transmitted can be multiplexed and transmitted on the same resource.

[0110] In some embodiments, before determining the encoding scheme for the UCI to be transmitted based on the ratio of the information lengths of the UCI to be transmitted of different priorities, the UCI multiplexing transmission method provided in the embodiment of the present application may further include:

[0111] When the information length of the high-priority UCI to be transmitted is greater than the first set length, and the information length of the low-priority UCI to be transmitted is greater than the second set length, a step is performed to determine the encoding method for each UCI to be transmitted based on the ratio of the information lengths of the UCI to be transmitted with different priorities; if the information length of the high-priority UCI to be transmitted is less than or equal to the first set length, or the information length of the low-priority UCI to be transmitted is less than or equal to the second set length, it is determined to perform joint encoding for each UCI to be transmitted.

[0112] That is to say, if the information length of the high-priority UCI to be transmitted is less than or equal to the first set length, and the information length of the low-priority UCI to be transmitted is greater than the second set length, it can be determined that joint coding is performed for each UCI to be transmitted. If the information length of the high-priority UCI to be transmitted is greater than the first set length, and the information length of the low-priority UCI to be transmitted is less than or equal to the second set length, it can also be determined that joint coding is performed for each UCI to be transmitted. If the information length of the high-priority UCI to be transmitted is less than or equal to the first set length, and the information length of the low-priority UCI to be transmitted is also less than or equal to the second set length, it can also be determined that joint coding is performed for each UCI to be transmitted.

[0113] The first set length and the second set length are predefined values ​​or values ​​configured by high-layer signaling; the high-layer signaling is RRC signaling or MAC CE signaling. The first set length and the second set length are positive integers.

[0114] For example, if the number of high-priority UCI bits to be transmitted is greater than a predefined number of bits, X, and the number of low-priority UCI bits to be transmitted is greater than a predefined number of bits, Y, then the coding scheme to be used when multiplexing the UCIs of different priorities on the same resource is determined based on the ratio of their information lengths. Otherwise, a joint coding scheme is always used. The number of bits, X, and Y, are positive integers that are predefined or configured by a higher layer.

[0115] In some embodiments, it can be determined that the resources corresponding to UCIs to be transmitted of different priorities overlap in the time domain in the following manner: if the resources corresponding to UCIs to be transmitted of different priorities overlap in the time domain, or the resources corresponding to UCIs to be transmitted of different priorities overlap with the third resource in the time domain, then it is determined that the resources corresponding to UCIs to be transmitted of different priorities overlap in the time domain. If the resources corresponding to UCIs to be transmitted of different priorities overlap in the time domain, the encoding method for each UCI to be transmitted can be determined based on the ratio of the information lengths of the UCIs to be transmitted of different priorities, and based on the determined encoding method, each UCI to be transmitted is encoded, and the encoded UCI is transmitted through the resources corresponding to the UCI to be transmitted of high priority.

[0116] For easier understanding, the following describes the UCI multiplexing transmission method performed by the terminal device through several specific embodiments.

[0117] Example 1

[0118] like Figure 3 As shown, a PUCCH resource carrying HP (High Priority) HARQ-ACK information and a PUCCH resource carrying LP (Low Priority) HARQ-ACK information overlap in the time domain, and the threshold value for selecting the predefined coding mode is 2.

[0119] Case 1: Assuming that the number of bits of HP HARQ-ACK information is 3 and the number of bits of LP HARQ-ACK information is 9, the ratio of the number of bits of HPHARQ-ACK information to the number of bits of LP HARQ-ACK information is 1 / 3, which is less than the threshold value of 2. In this case, it is determined that independent coding is used for multiplexing.

[0120] Case 2: Assuming that the number of bits of HP HARQ-ACK information is 9 and the number of bits of LP HARQ-ACK information is 3, the ratio of the number of bits of HPHARQ-ACK information to the number of bits of LP HARQ-ACK information is 3, which is greater than the threshold value 2. In this case, it is determined to use joint coding for multiplexing.

[0121] Case 3: Assuming that the number of bits of HP HARQ-ACK information is 6 and the number of bits of LP HARQ-ACK information is 3, the ratio of the number of bits of HPHARQ-ACK information to the number of bits of LP HARQ-ACK information is 2, which is equal to the threshold value 2. In this case, it is determined to use joint coding for multiplexing.

[0122] In this embodiment, the joint coding mode is selected for multiplexing as an example for description. In other embodiments, when the situation is 3, an independent coding mode may be selected for multiplexing.

[0123] After encoding each UCI to be transmitted based on the determined encoding method, the terminal device can transmit the encoded UCI through the HP PUCCH resource. The HP PUCCH resource is the PUCCH resource corresponding to the HP HARQ-ACK information, or the PUCCH resource carrying the HP HARQ-ACK information.

[0124] Example 2

[0125] like Figure 3 As shown, a PUCCH resource carrying HP HARQ-ACK information (ie, HP PUCCH) and a PUCCH resource carrying LPHARQ-ACK information (ie, LP PUCCH) overlap in the time domain. It is assumed that the threshold value for selecting the predefined coding mode configured by RRC signaling is 1. Figure 3 Slot in represents a time slot.

[0126] Case 1: Assuming the number of HP HARQ-ACK information bits is 3 and the corresponding code rate is 0.2, the number of coded bits of the HP HARQ-ACK information is 15. The number of LP HARQ-ACK information bits is 9 and the corresponding code rate is 0.5, the number of coded bits of the LP HARQ-ACK information is 18. The ratio of the number of coded bits of the HP HARQ-ACK information to the number of coded bits of the LP HARQ-ACK information is 5 / 6, which is less than the threshold value of 1. In this case, it is determined that independent coding is used for multiplexing.

[0127] Case 2: Assuming that the number of bits of HP HARQ-ACK information is 5 and the corresponding code rate is 0.2, the number of coded bits of HP HARQ-ACK is 25. The number of bits of LP HARQ-ACK information is 9 and the corresponding code rate is 0.5, the number of coded bits of LP HARQ-ACK information is 18, and the ratio of the number of coded bits of HP HARQ-ACK information to the number of coded bits of LP HARQ-ACK information is 25 / 18. If it is greater than the threshold value of 1, it is determined to use joint coding for multiplexing.

[0128] Case 3: Assuming that the number of bits of HP HARQ-ACK information is 2 and the corresponding code rate is 0.2, the number of coded bits of HP HARQ-ACK information is 10, the number of bits of LP HARQ-ACK information is 5, and the corresponding code rate is 0.5, the number of coded bits of LP HARQ-ACK information is 10, and the ratio of the number of coded bits of HP HARQ-ACK information to the number of coded bits of LP HARQ-ACK information is 1, which is equal to the threshold value 1. It is determined that joint coding is used for multiplexing.

[0129] In this embodiment, the joint coding mode is selected for multiplexing as an example for description. In other embodiments, when the situation is 3, an independent coding mode may be selected for multiplexing.

[0130] After encoding each UCI to be transmitted based on the determined encoding method, the terminal device can transmit the encoded UCI through the HP PUCCH resource. The HP PUCCH resource is the PUCCH resource corresponding to the HP HARQ-ACK information, or the PUCCH resource carrying the HP HARQ-ACK information.

[0131] Example 3

[0132] like Figure 3 As shown in FIG, a PUCCH resource carrying HP HARQ-ACK information and a PUCCH resource carrying LP HARQ-ACK information overlap in the time domain, the threshold value for selecting the predefined coding mode is 1, and the predefined X and Y values ​​are both 2. That is, only when the number of bits of the HP HARQ-ACK information and the LP HARQ-ACK information are both greater than 2, the coding mode is selected based on the threshold value 1, otherwise the joint coding mode is always used.

[0133] Case 1: Assuming that the number of bits of the HP HARQ-ACK information is 2 and the number of bits of the LP HARQ-ACK information is 6, since the number of bits of the HP HARQ-ACK information is not greater than 2, it is determined to use a joint coding method for multiplexing.

[0134] Case 2: Assuming that the number of bits of HP HARQ-ACK information is 5 and the number of bits of LP HARQ-ACK information is 6, the ratio of the number of bits of HP HARQ-ACK information to the number of bits of LP HARQ-ACK information is determined to be 5 / 6. If it is less than the threshold value 1, independent coding mode is selected for multiplexing.

[0135] Case 3: Assuming that the number of bits of HP HARQ-ACK information is 5 and the number of bits of LP HARQ-ACK information is 1, since the number of bits of LP HARQ-ACK information is not greater than 2, it is determined to use a joint coding method for multiplexing.

[0136] Case 4: Assuming that the number of bits of HP HARQ-ACK information is 4 and the number of bits of LP HARQ-ACK information is 2, the ratio of the number of bits of HP HARQ-ACK information to the number of bits of LP HARQ-ACK information is determined to be 2. If it is greater than the threshold value of 1, joint coding is selected for multiplexing.

[0137] Based on the determined coding method, after encoding each UCI to be transmitted, the terminal device can transmit the encoded UCI through the HP PUCCH resource, such as Figure 3 As shown by the arrow in , the HP PUCCH resource is the PUCCH resource corresponding to the HP HARQ-ACK information, or the PUCCH resource carrying the HP HARQ-ACK information.

[0138] Example 4

[0139] like Figure 4 As shown, a PUCCH resource carrying HP HARQ-ACK information (i.e., HP PUCCH) overlaps with an HP PUSCH resource in the time domain, and a PUCCH resource carrying LP HARQ-ACK information (i.e., LP PUCCH) also overlaps with the HP PUSCH resource in the time domain. Assume that the threshold value for selecting the predefined coding method is 2. Figure 4 The Slot in represents a time slot.

[0140] Case 1: Assuming that the number of bits of HP HARQ-ACK information is 2 and the number of bits of LP HARQ-ACK information is 6, the ratio of the number of bits of HPHARQ-ACK information to the number of bits of LP HARQ-ACK information is 1 / 3, which is less than the threshold value of 2. In this case, it is determined to use independent coding for multiplexing.

[0141] Case 2: Assuming that the number of bits of HP HARQ-ACK information is 6 and the number of bits of LP HARQ-ACK information is 2, the ratio of the number of bits of HPHARQ-ACK information to the number of bits of LP HARQ-ACK information is 3, which is greater than the threshold value of 2. In this case, it is determined to use joint coding for multiplexing.

[0142] Case 3: Assuming that the number of bits of HP HARQ-ACK information is 6 and the number of bits of LP HARQ-ACK information is 3, the ratio of the number of bits of HPHARQ-ACK information to the number of bits of LP HARQ-ACK information is 2, which is equal to the threshold value 2. In this case, it is determined to use joint coding for multiplexing.

[0143] In this embodiment, the joint coding mode is selected for multiplexing as an example for description. In other embodiments, when the situation is 3, an independent coding mode may be selected for multiplexing.

[0144] Based on the determined coding method, after encoding each UCI to be transmitted, the terminal device can transmit the encoded UCI through the HP PUSCH resource, such as Figure 4 As shown by the arrow in .

[0145] The method performed by the network side device 100 is as follows Figure 5 As shown, the following steps are included:

[0146] Step S501 : For received UCI to be decoded, a coding mode for the UCI is determined based on a ratio of information lengths of UCIs of different priorities contained in the UCI to be decoded.

[0147] The UCI to be decoded is coded UCI transmitted via the same resource. The coded UCI is obtained by encoding the UCI to be transmitted based on the determined coding scheme, after the terminal device determines that resources corresponding to the UCI to be transmitted of different priorities overlap in the time domain, based on the ratio of the information lengths of the UCI to be transmitted of different priorities.

[0148] Taking the network side device 100 as an example, which is a base station, since the physical channel resources used by the terminal device and the information length of the UCI carried on the physical channel resources are scheduled by the base station, or determined by the terminal device and the base station according to the protocol, the base station can obtain the information length of UCI of different priorities contained in the received UCI to be decoded, and determine the encoding method for UCI based on the ratio of the information lengths of UCI of different priorities contained in the UCI to be decoded.

[0149] The specific process of the base station determining the coding method for UCI is the same as the specific process of the terminal device determining the coding method for UCI to be transmitted, so it can be executed with reference to the above and will not be repeated here.

[0150] Step S502: Decode the UCI based on the determined encoding method to obtain data in the UCI.

[0151] The network-side device uses a method corresponding to that of the terminal device to determine the encoding method for UCI based on the ratio of the information lengths of UCIs of different priorities. This allows the network-side device to decode the UCI transmitted on the same resource based on the determined encoding method to obtain the data in the UCI, thereby reducing the phenomenon of discarding low-priority physical channel resources when physical channels of different priorities overlap in the time domain.

[0152] For example, in one embodiment, assuming that the number of bits of the high-priority UCI to be transmitted is 6 and the number of bits of the low-priority UCI to be transmitted is 3, the ratio of the number of bits of the high-priority UCI to be transmitted to the number of bits of the low-priority UCI to be transmitted is 2, which is equal to the threshold value 2. The terminal device determines to use a joint coding method to encode the UCI to be transmitted and transmits the encoded UCI through the high-priority PUCCH resource. The base station receives the UCI to be decoded transmitted through the high-priority PUCCH resource, and determines that the ratio of the number of bits of the high-priority UCI to the number of bits of the low-priority UCI is 2, which is equal to the threshold value 2, that is, it determines that the coding method for UCI is joint coding. Based on the determined coding method, the base station decodes the UCI and obtains the data in the UCI.

[0153] In another embodiment, assuming that the number of bits of the high-priority UCI to be transmitted is 6 and the number of bits of the low-priority UCI to be transmitted is 3, the ratio of the number of bits of the high-priority UCI to be transmitted to the number of bits of the low-priority UCI to be transmitted is 2, which is equal to the threshold value 2. The terminal device determines to use an independent coding method to encode the UCI to be transmitted and transmits the encoded UCI through the high-priority PUCCH resource. The base station receives the UCI to be decoded transmitted through the high-priority PUCCH resource, and determines that the ratio of the number of bits of the high-priority UCI to the number of bits of the low-priority UCI is 2, which is equal to the threshold value 2, that is, it determines that the coding method for UCI is independent coding. Based on the determined coding method, the base station decodes the UCI and obtains the data in the UCI.
