Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS The present invention claims priority to a Chinese patent application filed with the China Patent Office on December 9, 2020, bearing application number 202011429692.3 and entitled "Uplink control information transmission method, apparatus, terminal and network side equipment", the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of wireless communication, and in particular to an uplink control information transmission method, device, terminal, and network side device. [Background technology]

[0003] In a New Radio (NR) system, one User Equipment (UE) may support different services simultaneously, and it is considered that different services correspond to different service requirements, such as delay, reliability, etc. Therefore, a mechanism for labeling the priority of the Physical Uplink Control Channel (PUCCH) and / or the Physical Uplink Shared Channel (PUSCH) has been introduced. Specifically, two levels of physical layer priority, such as high priority and low priority, have been introduced.

[0004] When the time domain resources of PUCCHs with different priorities overlap, if the low priority PUCCH is simply discarded, it will have a large impact on the performance of low priority service transmission. Therefore, in order to reduce the impact on low priority transmission, multiplexing between PUCCHs with different priorities is supported in the current communication system. For example, when the time domain resources of a high priority (High Priority, HP) Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) PUCCH and a low priority (Low Priority, LP) HARQ-ACK PUCCH overlap and a certain condition is met, the UE multiplexes the HP HARQ-ACK and the LP HARQ-ACK into one PUCCH for transmission. In order to meet different reliability requirements and improve resource utilization, the LP HARQ-ACK and the HP HARQ-ACK need to be coded respectively. At this time, the PUCCH may further be multiplexed with channel state information (Channel State Information, CSI), for example, LP CSI. In addition, when CSI includes a first part of channel state information (CSI-part 1) and a second part of channel state information (CSI-part 2), a base station cannot decode CSI-part 2 unless it first decodes CSI-part 1, and therefore CSI-part 1 and CSI-part 2 need to be coded separately. In such a case, uplink control information (UCI) multiplexed onto one physical uplink channel includes HARQ-ACKs and CSIs with different priorities, and how to transmit HARQ-ACKs and CSIs with different priorities on one physical uplink channel is currently a technical problem that needs to be solved.

[0020] FIG. 1 shows a schematic diagram of a wireless communication system applicable to the embodiment of the present application.

In the embodiments of the present application, only a base station in an NR system is taken as an example, but it should be explained that the specific type of the base station is not limited.

[0021] Hereinafter, a method for transmitting uplink control information provided in an embodiment of the present application will be described in detail with reference to the drawings according to specific embodiments and application cases.

[0022] 2 shows a schematic flow chart of an uplink control information transmission method in an embodiment of the present application, and the method 200 may be performed by a terminal. In other words, the method may be performed by software or hardware implemented in the terminal. As shown in FIG. 2, the method may include the following steps S210, S212 and S214.

[0023] At S210, the terminal determines uplink control information to be multiplexed and transmitted onto one target physical uplink channel, the uplink control information includes a first HARQ-ACK, a second HARQ-ACK and CSI, and the priority of the first HARQ-ACK is higher than that of the second HARQ-ACK.

[0024] That is, in the embodiment of the present application, the first HARQ-ACK is a high priority (HP) HARQ-ACK, and the second HARQ-ACK is a low priority (LP) HARQ-ACK. That is, in the embodiment of the present application, HARQ-ACKs and CSIs of different priorities need to be multiplexed and transmitted to the target physical uplink channel. In the embodiment of the present application, the priority may be represented by a priority index, for example, priority index 0 represents low priority, and priority index 1 represents high priority.

[0025] For example, when the time domain resources of the PUCCH carrying the first HARQ-ACK and the PUCCH carrying the second HARQ-ACK overlap and a certain condition is met, the UE needs to multiplex the first HARQ-ACK and the second HARQ-ACK into one PUCCH for transmission. At the same time, the time domain resources of the PUCCH carrying the first HARQ-ACK, the PUCCH carrying the second HARQ-ACK, or the PUCCH multiplexing the first HARQ-ACK and the second HARQ-ACK and the PUCCH carrying CSI overlap, so that the first HARQ-ACK, the second HARQ-ACK, and the CSI need to be multiplexed into one PUCCH.

[0026] In S212, an encoding scheme for the uplink control information in the target physical uplink channel is determined depending on the priority of the CSI and / or whether the CSI includes CSI-part 2, where the priority of the CSI includes a first priority or a second priority, and the first priority is higher than the second priority.

[0027] That is, in the embodiment of the present application, the priority of CSI may be high priority (i.e., first priority) or low priority (i.e., second priority). When determining how to encode the first HARQ-ACK, the second HARQ-ACK, and the CSI to be transmitted on the target physical uplink channel, the terminal determines the encoding scheme of the uplink control information according to the priority of the CSI and / or whether the CSI includes CSI-part2.

[0028] In an embodiment of the present application, the target physical uplink channel may include a PUCCH.

[0029] In one possible implementation, when the target physical uplink channel is PUCCH, in S212, when determining the coding scheme for the uplink control information, if the CSI includes CSI-part 2, it is determined to adopt one of the following coding schemes 1 to 4.

[0030] In method 1, the first HARQ-ACK and CSI-part 1 in the CSI are jointly encoded, and the second HARQ-ACK and CSI-part 2 are jointly encoded.

[0031] In method 2, the first HARQ-ACK is encoded independently, the second HARQ-ACK and the CSI-part 1 are encoded jointly, and the CSI-part 2 is discarded.

[0032] As is necessary to explain, the joint coding of A and B and the joint coding of C and D described in the embodiments of the present application means that A and B are jointly coded to form one coded stream, and C and D are jointly coded to form another coded stream, and "A and B" and "C and D" are coded separately. For example, when the above coding scheme 1 is adopted to code uplink control information, the first HARQ-ACK and CSI-part 1 in the CSI are jointly coded, and the second HARQ-ACK and CSI-part 2 are jointly coded. For example, two encoders can be used, one encoder codes the first HARQ-ACK and CSI-part 1 in the CSI, and the other encoder codes the second HARQ-ACK and CSI-part 2 jointly.

[0033] For the same reason, independently encoding A and jointly encoding C and D means independently encoding A to form one encoded stream and jointly encoding C and D to form another encoded stream, rather than jointly encoding A with C and D. Other similar descriptions have similar meanings and will not be described in detail.

[0034] Alternatively, if the priority of the CSI is the first priority or the second priority and the CSI does not include CSI-part 2, it is decided to adopt one of the following encoding methods, Scheme 3 and Scheme 4.

[0035] In method 3, the CSI and the second HARQ-ACK are jointly coded, and the first HARQ-ACK is independently coded.

[0036] In method 4, the CSI and the first HARQ-ACK are jointly coded, and the second HARQ-ACK is independently coded.

[0037] In other words, in the above possible implementation form, the coding scheme of the uplink control information may be determined depending on whether or not the CSI includes CSI-part 2. If the CSI includes CSI-part 2, the coding scheme of the uplink control information may be determined to be the above-mentioned scheme 1 or scheme 2. If the CSI does not include CSI-part 2, the coding scheme of the uplink control information may be determined to be the above-mentioned scheme 3 or scheme 4.

[0038] Alternatively, the coding scheme for the uplink control information may be determined according to the priority of the CSI, or according to the priority of the CSI and whether or not CSI-part 2 is included in the CSI.

[0039] For example, if the priority of the CSI is the first priority, the coding scheme of the uplink control information is (1) if the CSI includes CSI-part 2, jointly encoding the first HARQ-ACK and CSI-part 1 in the CSI, and jointly encoding the second HARQ-ACK and the CSI-part 2; (2) if the CSI includes CSI-part 2, independently encoding the first HARQ-ACK, jointly encoding the second HARQ-ACK and CSI-part 1, and discarding CSI-part 2; (3) if the CSI does not include CSI-part 2, jointly encoding the CSI and the second HARQ-ACK and independently encoding the first HARQ-ACK; (4) If the CSI does not include CSI-part 2, jointly encode the CSI and the first HARQ-ACK, and independently encode the second HARQ-ACK.

[0040] Alternatively, if the priority of the CSI is the second priority and the CSI includes CSI-part 2, it is determined that the coding scheme of the uplink control information is Scheme 1 or Scheme 2. If the CSI does not include CSI-part 2, it is determined that the coding scheme of the uplink control information is to jointly code CSI-part 1 and the first HARQ-ACK and to independently code the second HARQ-ACK.

[0041] For example, in Figure 3a, the resources of LP HARQ-ACK PUCCH, which is a PUCCH including LP HARQ-ACK, SP-CSI PUCCH, which is a PUCCH including semi-persistent CSI (SP-CSI), and HP HARQ-ACK PUCCH, which is a PUCCH including HP HARQ-ACK, overlap, and at this time, if the overlap between PUCCHs of the same priority is processed first, and then the overlap between PUCCHs of different priority is processed, then the SP-CSI and LP HARQ-ACK are multiplexed into one PUCCH. If the PUCCH channel after multiplexing still overlaps with the HP HARQ-ACK PUCCH and satisfies the multiplexing condition of the LP PUCCH and the HP HARQ-ACK, the UE multiplexes the LP HARQ-ACK, HP HARQ-ACK, and SP-CSI into one PUCCH for transmission. Alternatively, as shown in Figure 3b, when one of the two PUCCHs is a PUCCH multiplexed with LP HARQ-ACK and periodic CSI (P-CSI), and the other is an HP HARQ-ACK PUCCH, and the time domain resources of the two PUCCHs overlap and the conditions for multiplexing between PUCCHs with different priorities are met, the UE multiplexes the LP HARQ-ACK, HP HARQ-ACK and P-CSI into one PUCCH for transmission.

[0042] Since the SP-CSI or P-CSI included in the PUCCH is low-priority UCI, the UE determines that the coding schemes of the HP HARQ-ACK, the LP HARQ-ACK, and the CSI are (1) if the CSI includes CSI-part 2, jointly encode the HP HARQ-ACK and CSI-part 1, and jointly encode the LP HARQ-ACK and CSI-part 2; (2) if the CSI includes CSI-part 2, encode the HP HARQ-ACK separately, jointly encode the LP HARQ-ACK and CSI-part 1, and discard CSI-part 2; (3) if the CSI does not include CSI-part 2 (e.g., P-CSI), jointly encode CSI-part 1 and the LP HARQ-ACK, and independently encode the HP HARQ-ACK; (4) If the CSI does not include CSI-part 2, it may be determined that the following option is available: jointly encode CSI-part 1 and the HP HARQ-ACK, and independently encode the LP HARQ-ACK.

[0043] Further, for example, in Figure 3c, if the resources of the LP HARQ-ACK PUCCH, the HP CSI PUCCH (i.e., the PUCCH including the high priority CSI), and the HP HARQ-ACK PUCCH overlap, and the overlap between the PUCCHs with the same priority is processed first, and then the overlap between the PUCCHs with different priorities is processed, then the HP CSI and the HP HARQ-ACK are multiplexed into one PUCCH. Assuming that the multiplexed channel still overlaps with the LP HARQ-ACK PUCCH and satisfies the conditions for multiplexing the LP PUCCH and the HP PUCCH, the UE multiplexes the LP HARQ-ACK, the HP HARQ-ACK, and the HP CSI into one PUCCH for transmission. Alternatively, as shown in Figure 3d, when one of the two PUCCHs is a PUCCH multiplexed with HP HARQ-ACK and HP CSI, and the other is a LP HARQ-ACK PUCCH, and the time domain resources of the two PUCCHs overlap and the conditions for multiplexing between PUCCHs with different priorities are met, the UE multiplexes the LP HARQ-ACK, HP HARQ-ACK and HP CSI into one PUCCH for transmission.

[0044] At this time, since the CSI included in the PUCCH is high-priority CSI, the UE determines whether the coding scheme of the HP HARQ-ACK, the LP HARQ-ACK, and the CSI is (1) if the CSI includes CSI-part 2, jointly encode the HP HARQ-ACK and CSI-part 1, and jointly encode the LP HARQ-ACK and CSI-part 2; (2) If the CSI does not include CSI-part 2, it may be determined that the CSI-part 1 and the HP HARQ-ACK are jointly encoded, and the LP HARQ-ACK is encoded separately.

[0045] In one possible implementation, the uplink control information may further include a first Scheduling Request (SR) and / or a second SR, where the priority of the first SR is higher than the priority of the second SR, i.e., in this possible implementation, the first SR is a HP SR and the second SR is a LP SR.

[0046] In the above possible implementation form, the step S212 of determining a coding scheme for uplink control information may further include a step of determining to jointly code the first SR and the first HARQ ACK, and / or to jointly code the second SR and the second HARQ ACK. For example, if the priority of the CSI is the first priority, the coding scheme of the uplink control information is determined to be, if the CSI includes CSI-part 2, to jointly code the first HARQ-ACK, the first SR, and the CSI-part 1, and to jointly code the second HARQ-ACK, the second SR, and the CSI-part 2, and, if the CSI does not include CSI-part 2, to jointly code the first HARQ-ACK, the first SR, and the CSI-part 1, and to jointly code the second HARQ-ACK and the second SR.

[0047] Further, for example, if the priority of the CSI is the second priority, the coding scheme of the uplink control information is (1) if CSI includes CSI-part 2, jointly encoding the first HARQ-ACK, the first SR, and the CSI-part 1, and jointly encoding the second HARQ-ACK, the second SR, and the CSI-part 2; (2) if the CSI does not include CSI-part 2, jointly encoding the first HARQ-ACK and the first SR, and jointly encoding the second HARQ-ACK, the second SR, and the CSI-part 1; (3) If the CSI does not include CSI-part 2, determine that the CSI-part 1, the first SR, and the first HARQ-ACK are jointly encoded, and the second HARQ-ACK and the second SR are jointly encoded.

[0048] That is, in the embodiment of the present application, the UCI multiplexed in one PUCCH may further include SR in addition to HP HARQ-ACK, LP HARQ-ACK and CSI, where SR may include only LP SR, may include only HP SR, or may include both LP SR and HP SR. In this case, the UE may encode each UCI in the following manner: First, if the CSI is LP CSI (i.e., second-priority CSI), the coding manner of the UCI in the PUCCH is determined according to whether the LP CSI includes CSI-part 2: (1) If the CSI includes CSI-part 2, jointly encode the HP HARQ-ACK, the HP SR (if present), and CSI-part 1, and jointly encode the LP HARQ-ACK, the LP SR (if present), and CSI-part 2; (2) If the CSI does not include CSI-part 2, (1) jointly encoding CSI-part 1, LP HARQ-ACK, and LP SR (if present), and jointly encoding HP HARQ-ACK and HP SR (if present); (2) jointly encode CSI-part 1, the HP HARQ-ACK, and the HP SR (if present), and jointly encode the LP HARQ-ACK and the LP SR (if present); 2. If the CSI is HP CSI, the coding method of the UCI in the PUCCH is determined according to whether the HP CSI includes CSI-part 2: (1) If the CSI includes CSI-part 2, jointly encode the HP HARQ-ACK, the HP SR (if present), and CSI-part 1, and jointly encode the LP HARQ-ACK, the LP SR (if present), and CSI-part 2; (2) If the CSI does not include CSI-part 2, determine that CSI-part 1, HP HARQ-ACK, and HP SR (if present) are jointly encoded, and LP HARQ-ACK and LP SR (if present) are jointly encoded.

[0049] According to the above possible implementation, when HP HARQ-ACK, LP HARQ-ACK, CSI and SR are simultaneously multiplexed in a PUCCH, the coding mode of the uplink control information in the PUCCH can be determined to resolve resource collision.

[0050] In an embodiment of the present application, the target physical uplink channel may include a physical uplink shared channel (PUSCH). For example, when the resources of the PUCCH and the PUSCH overlap, the UE multiplexes the UCI transmitted on the PUCCH onto the PUSCH for transmission.

[0051] In the above possible implementation, when the target physical uplink channel is a PUSCH, when determining the coding scheme of the uplink control information in S212, the coding scheme of the uplink control information may be determined according to whether the CSI includes CSI-part 2. For example, if the CSI does not include CSI-part 2, it is determined that the first HARQ-ACK, the second HARQ-ACK, and the CSI are each independently coded.

[0052] Alternatively, the coding scheme of the uplink control information may be determined according to the priority of the CSI. For example, if the priority of the CSI is the second priority and the CSI does not include CSI-part 2, the coding scheme of the uplink control information is determined to be Scheme 1 or Scheme 2 below.

[0053] In method 1, the first HARQ-ACK, the second HARQ-ACK, and the CSI are coded independently.

[0054] In method 2, the first HARQ-ACK is encoded independently, and the second HARQ-ACK and the CSI are jointly encoded.

[0055] Alternatively, the step S212 of determining a coding scheme for the uplink control information in the target physical uplink channel may include a step of determining that the coding scheme for the uplink control information is at least one of the following schemes 3 to 9 if the priority of the CSI is second priority and the CSI includes CSI-part 2.

[0056] In method 3, the first HARQ-ACK is coded independently, the second HARQ-ACK and CSI-part 1 of the CSI are coded jointly, and CSI-part 2 of the CSI is coded independently.

[0057] In method 4, the first HARQ-ACK and the second HARQ-ACK are jointly encoded, CSI-part 1 of the CSI is independently encoded, and CSI-part 2 of the CSI is independently encoded.

[0058] In method 5, the first HARQ-ACK and CSI-part 1 of the CSI are jointly encoded, and the second HARQ-ACK and CSI-part 2 are jointly encoded.

[0059] In the sixth method, the first HARQ-ACK is encoded independently, the second HARQ-ACK is encoded independently, and CSI-part 1 and CSI-part 2 of the CSI are jointly encoded.

[0060] By selectively adopting the above-mentioned methods 3 to 6, the terminal may determine the number of bits after encoding of CSI-part 2 and / or the number of resource elements RE to be occupied in a predefined manner. For example, assuming rank=1, the terminal determines the number of bits of the corresponding CSI-part 2, determines the number of bits after encoding of CSI-part 2 and / or the number of resource elements RE to be occupied based on the number of bits, and then performs encoding and / or resource mapping on the CSI-part 2 to be actually transmitted based on the determined number of bits after encoding and / or the number of resource elements RE to be occupied.

[0061] In method 7, the first HARQ-ACK is coded separately, the second HARQ-ACK is coded separately, CSI-part 1 of the CSI is coded separately, and the CSI-part 2 is discarded.

[0062] In the above possible implementation form, if the target physical uplink channel is a PUSCH, when determining the coding scheme of the uplink control information in S212, if the priority of the CSI is the first priority and the CSI does not include CSI-part 2, it is determined that the coding scheme of the uplink control information is one of the following:

[0063] In scheme 8, the first HARQ-ACK, the second HARQ-ACK, and the CSI are coded independently.

[0064] In scheme 9, the first HARQ-ACK and the CSI are jointly encoded, and the second HARQ-ACK is independently encoded.

[0065] Optionally, if the priority of the CSI is the first priority and the CSI includes CSI-part 2, the coding scheme is determined to be at least one of schemes 10 to 16 below.

[0066] In scheme 10, the first HARQ-ACK and CSI-part 1 of the CSI are jointly encoded, the second HARQ-ACK is independently encoded, and CSI-part 2 of the CSI is independently encoded.

[0067] In method 11, the first HARQ-ACK and the second HARQ-ACK are jointly encoded, CSI-part 1 of the CSI is independently encoded, and CSI-part 2 of the CSI is independently encoded.

[0068] In method 12, the first HARQ-ACK and CSI-part 1 of the CSI are jointly encoded, and the second HARQ-ACK and CSI-part 2 are jointly encoded.

[0069] In method 13, the first HARQ-ACK is coded separately, the second HARQ-ACK is coded separately, and CSI-part 1 and CSI-part 2 of the CSI are coded jointly.

[0070] By selectively adopting the above-mentioned methods 2 to 13, the terminal may determine the number of bits after encoding of CSI-part 2 and / or the number of resource elements RE to be occupied in a predefined manner. For example, assuming rank=1, the terminal determines the number of bits of the corresponding CSI-part 2, determines the number of bits after encoding of CSI-part 2 and / or the number of resource elements RE to be occupied based on the number of bits, and then performs encoding and / or resource mapping on the CSI-part 2 to be actually transmitted based on the determined number of bits after encoding and / or the number of resource elements RE to be occupied.

[0071] In method 14, the first HARQ-ACK is coded separately, the second HARQ-ACK is coded separately, CSI-part 1 of the CSI is coded separately, and the CSI-part 2 is discarded.

[0072] In method 15, the first HARQ-ACK is encoded independently, the second HARQ-ACK and the CSI-part 1 are encoded jointly, and the CSI-part 2 is discarded.

[0073] Scheme 16: the first HARQ-ACK is encoded separately, the CSI-part 1 is encoded separately, the second HARQ-ACK is encoded separately, and the CSI-part 2 is discarded.

[0074] For example, in Fig. 4a, when the time domain resources of PUCCH and PUSCH multiplexed with HP HARQ-ACK, LP HARQ-ACK and LP CSI overlap and the multiplexing requirement of PUCCH and PUSCH is satisfied, the UE multiplexes the HP HARQ-ACK, LP HARQ-ACK and LP CSI included in the PUCCH onto the PUSCH.Furthermore, in Fig. 4b, when one PUCCH including HP HARQ-ACK and one PUCCH including LP HARQ-ACK and LP CSI overlap with the time domain resource of one PUSCH at the same time and both satisfy the multiplexing requirement of PUCCH and PUSCH, the UE multiplexes the UCI included in the two PUCCHs onto the PUSCH.

[0075] In this case, when determining coding of uplink control information in the PUSCH, the UE may determine a coding scheme for the uplink control information according to whether the CSI includes CSI-part 2. For example, if the CSI does not include CSI-part 2, the coding scheme may include one of the following schemes 1 and 2:

[0076] In the first method, the HP HARQ-ACK, the LP HARQ-ACK, and the CSI are coded separately, that is, the HP HARQ-ACK, the LP HARQ-ACK, and the CSI are coded independently.

[0077] In the second method, the HP HARQ-ACK and the LP HARQ-ACK+CSI are coded separately, that is, the HP HARQ-ACK is coded separately, and the LP HARQ-ACK and CSI are coded jointly.

[0078] If the CSI includes CSI-part 2, the encoding method may include one of the following items:

[0079] In method 1, HP HARQ-ACK, LP HARQ-ACK+CSI-part 1, and CSI-part 2 are encoded, respectively.

[0080] In method 2, HP HARQ-ACK+LP HARQ-ACK, CSI-part 1, and CSI-part 2 are encoded, respectively.

[0081] In method 3, HP HARQ-ACK+CSI-part 1 and LP HARQ-ACK+CSI-part 2 are encoded separately.

[0082] In method 4, HP HARQ-ACK, LP HARQ, and CSI-part 1+CSI-part 2 are encoded.

[0083] In method 5, the HP HARQ-ACK, the LP HARQ-ACK, and CSI-part 1 are encoded, and CSI-part 2 is discarded.

[0084] Alternatively, the coding scheme of the uplink control information may be determined according to the priority of the CSI. For example, if the CSI is HP CSI, the coding scheme adopted by the UE may include one of the following:

[0085] In method 1, HP HARQ-ACK+CSI-part 1, LP HARQ-ACK, and CSI-part 2 are encoded respectively.

[0086] In method 2, HP HARQ-ACK+LP HARQ-ACK, CSI-part 1, and CSI-part 2 are encoded, respectively.

[0087] In method 3, HP HARQ-ACK+CSI-part 1 and LP HARQ-ACK+CSI-part 2 are encoded, respectively.

[0088] In method 4, HP HARQ-ACK, LP HARQ, and CSI-part 1+CSI-part 2 are encoded.

[0089] In method 5, the HP HARQ-ACK, the LP HARQ-ACK, and CSI-part 1 are encoded, and CSI-part 2 is discarded.

[0090] In method 6, the HP HARQ-ACK and the LP HARQ-ACK+CSI-part 1 are encoded, and CSI-part 2 is discarded.

[0091] In method 7, the HP HARQ-ACK, CSI-part 1, and LP HARQ-ACK are encoded, and CSI-part 2 is discarded.

[0092] Here, which method the terminal adopts may be configured by higher layer signaling on the network side or may be specified by a protocol, and is not limited by the embodiments of the present application.

[0093] In S214, the uplink control information is coded according to the coding scheme, and the coded uplink control information is transmitted on the target physical uplink channel.

[0094] The UE encodes the uplink control information according to the determined coding scheme. Specifically, the UE may encode the uplink control information waiting to be transmitted using a number of encoders corresponding to the number of coding parts determined by the coding scheme. For example, if the target physical uplink channel is a PUCCH, the uplink control information may be encoded using two encoders. If the encoding is performed according to the above-mentioned scheme 1 when the target physical uplink channel is a PUCCH, one of the encoders jointly encodes the first HARQ-ACK and CSI-part 1 in the CSI, and the other encoder jointly encodes the second HARQ-ACK and the CSI-part 2, and transmits the encoded uplink control information on the target physical uplink channel.

[0095] In the above technical means provided in the embodiments of the present application, when a terminal determines that uplink control information required to be transmitted on one target physical uplink channel includes a high priority HARQ-ACK, a low priority HARQ-ACK, and CSI, the terminal determines a coding scheme for the uplink control information on the target physical uplink channel according to the priority of the CSI and / or whether the CSI includes CSI-part 2, and encodes and transmits the uplink control information using the determined coding scheme, thereby solving the problem of how to multiplex and transmit HARQ-ACKs and CSI of different priorities on one physical uplink channel.

[0096] 5 shows another schematic flow chart of an uplink control information transmission method in an embodiment of the present application, and the method 500 may be performed by a network side device. In other words, the method may be performed by software or hardware implemented in the network side device. As shown in FIG. 5, the method may include the following steps S510, S512 and S514.

[0097] At S510, a network side device determines uplink control information to be multiplexed and transmitted by a terminal onto one target physical uplink channel, the uplink control information includes a first HARQ-ACK, a second HARQ-ACK and CSI, and the priority of the first HARQ-ACK is higher than that of the second HARQ-ACK.

[0098] Here, S510 corresponds to S210, and the network side device determines that uplink control information including the first HARQ-ACK, the second HARQ-ACK and CSI needs to be multiplexed and transmitted to one target physical uplink channel of the terminal. For details, refer to the relevant description in the above method 200, and detailed description is omitted here.

[0099] In S512, an encoding scheme for the uplink control information on the target physical uplink channel is determined depending on the priority of the CSI and / or whether the CSI includes a second part of channel state information CSI-part 2, where the priority of the CSI includes a first priority and a second priority, and the first priority is higher than the second priority.

[0100] Optionally, the target physical uplink channel may include a PUCCH.

[0101] Optionally, the network side equipment may adopt each possible implementation form corresponding to the terminal to determine the coding scheme of the uplink control information transmitted on the PUCCH, specifically, refer to the relevant description in the above method 200, and detailed description is omitted here.

[0102] In one possible implementation, the first HARQ-ACK and the second HARQ-ACK are multiplexed and transmitted on one PUCCH, the first HARQ-ACK and the second HARQ-ACK are independently coded, and when the terminal may not want to multiplex CSI on the PUCCH, the network side device should ensure that only the first HARQ-ACK and the second HARQ-ACK are included as uplink control information to be multiplexed on the PUCCH when scheduling the terminal. Therefore, in this possible implementation, the method may further include the step of multiplexing the first HARQ-ACK and the second HARQ-ACK on one target physical uplink channel and transmitting the same, the first HARQ-ACK and the second HARQ-ACK are independently coded, and when the terminal may not want to multiplex CSI on the target physical uplink channel, the network side device should ensure that only two pieces of information that need to be independently coded are included as uplink control information to be multiplexed on the target physical uplink channel when scheduling the terminal.

[0103] For example, in Figure 6, the LP HARQ-ACK PUCCH and the HP HARQ-ACK PUCCH overlap and meet the condition of multiplexing HARQ-ACKs with different priorities, and the UE multiplexes the LP HARQ-ACK and the HP HARQ-ACK into one PUCCH, and thus the UE does not want the multiplexed PUCCH to overlap with the CSI PUCCH. Or, the UE does not want the LP HARQ-ACK to overlap with the HP HARQ-ACK PUCCH and the CSI PUCCH at the same time. Or, the UE does not want the HP HARQ-ACK to overlap with the LP HARQ-ACK PUCCH and the CSI PUCCH at the same time. In this way, when the network side device schedules the terminal, it ensures that the uplink control information to be multiplexed onto the target physical uplink channel contains only two pieces of information that need to be coded independently, i.e., it does not simultaneously schedule the UE to transmit HP HARQ-ACK, LP HARQ-ACK PUCCH and CSI in overlapped PUCCHs, for example, it allocates different time domain resources to the PUCCHs of HP HARQ-ACK and LP HARQ-ACK and the PUCCH of CSI.

[0104] Optionally, the target physical uplink channel may include a PUSCH.

[0105] Optionally, the network side device may determine the coding scheme of the uplink control information transmitted on the PUSCH by adopting each possible implementation form corresponding to the terminal, specifically, refer to the relevant description in the above method 200, and detailed description here will be omitted.

[0106] At S514, uplink control information transmitted on the target uplink control channel is received according to the coding scheme.

[0107] The network side device decodes the uplink control information transmitted on the target uplink control channel according to the determined coding scheme, and obtains each part of the uplink control information transmitted by the UE.

[0108] According to the above-mentioned uplink control information transmission method provided in the embodiment of the present application, when UCI information transmitted on PUCCH and / or PUSCH includes HARQ-ACK and CSI with different priorities, the reliability of various UCI information is ensured and resource utilization is improved without increasing the number of UCI encoders, thereby improving the effectiveness of the communication system.
