Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and more particularly, to an uplink control information transmission method and device. BACKGROUND

[0002] For enhanced mobile broadband (eMBB) services and ultra reliable and low latency communications (URLLC) services, uplink control information (UCI) can be divided into high priority UCI and low priority UCI. Among them, the high priority UCI corresponds to the URLLC service, and the low priority UCI corresponds to the eMBB service.

[0003] Currently, it is discussed to multiplex and transmit high and low priority UCI together, so there may be a case where a physical uplink channel carries both high priority UCI and low priority UCI. Simultaneously carrying high and low priority UCI on the physical uplink channel increases the processing complexity and cost of the terminal device, thereby affecting the working performance of the terminal device. Therefore, how to better transmit uplink control information has become a technical problem to be solved at present. SUMMARY

[0004] The present application provides an uplink control information transmission method and device, which realizes transmitting uplink control information within the capability range of the terminal device and guarantees the working performance of the terminal device.

[0005] In a first aspect, an uplink control information transmission method is provided, which includes: a terminal device determines N uplink control information, N is an integer and greater than 3, the N uplink control information includes first uplink control information and second uplink control information, and the priority of the second uplink control information is higher than that of the first uplink control information; the terminal device transmits a physical uplink channel carrying the N uplink control information, wherein the first uplink control information and the second uplink control information are concatenated and encoded, or; the terminal device discards the first uplink control information and transmits a physical uplink channel carrying the second uplink control information.

[0006] In the present application, one or more uplink control information can be included in the first uplink control information, and one or more uplink control information can also be included in the second uplink control information.

[0007] In a possible implementation, the terminal device discards the first uplink control information and transmits a physical uplink channel carrying the second uplink control information. It can be understood that the terminal device transmits a physical uplink channel carrying high priority uplink control information.

[0008] In one possible implementation, the terminal device discards the first uplink control information and transmits a physical uplink channel carrying the second uplink control information. This can be understood as the terminal device discarding some low-priority uplink control information and transmitting a physical uplink channel carrying both high-priority and some low-priority uplink control information.

[0009] In one possible implementation, the terminal device discards the first uplink control information and transmits the physical uplink channel carrying the second uplink control information. This can be understood as the terminal device potentially discarding or transmitting a third uplink control information. The N uplink control messages also include the third uplink control information.

[0010] In other words, in this application, the terminal device can transmit a physical uplink channel carrying the second uplink control information, but this application does not limit whether the terminal device can also transmit other uplink control information among the N uplink control information. This application does not exclude the possibility that the terminal device can discard part of the first uplink control information and transmit information carrying the second uplink control information and some other uplink control information.

[0011] Based on the above technical solution, the terminal device can determine N uplink control messages to be sent, where N is an integer greater than 3. That is, in this application, the number of uplink control messages to be sent by the terminal device can be greater than 3. However, when sending the uplink control messages, the number of sent uplink control messages can be ensured not to exceed the maximum number of independently encoded uplink control messages by using joint encoding or discarding methods. This allows uplink control messages to be sent within the capabilities of the terminal device, ensuring its operational performance.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the terminal device discards the first uplink control information, including: when N is greater than a first threshold, the terminal device discards the first uplink control information.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the first UCI and the second UCI are concatenated and then encoded, including: when N is greater than a first threshold, the terminal device concatenates and encodes the first uplink control information and the second uplink control information.

[0014] In this application, the first threshold may be the number or maximum number of independently encoded uplink control information, the total or maximum number of independently encoded UCI bit sequences, the total number of code blocks encoded by uplink control information, or the total number of code blocks encoded by each independently encoded UCI bit sequence.

[0015] Based on the above technical solution, the terminal device can also introduce judgment conditions before discarding uplink control information or jointly encoding uplink control information, so that uplink control information can be sent within the capabilities of the terminal device, thus ensuring the working performance of the terminal device.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the first threshold is indicated by the network device, or the first threshold is determined based on the capabilities reported by the terminal device, or the first threshold is predefined.

[0017] Based on the above technical solution, the first threshold can be flexibly determined in this application to ensure that it does not exceed the processing capacity of the terminal device and to guarantee the working performance of the terminal device.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the reporting capability of the terminal device includes at least one of the following: the number of independently coded uplink control information supported by the terminal device is greater than 3; or the maximum number of independently coded uplink control information supported by the terminal device; or the terminal device supports code blocks of more than 6 polar codes; or the terminal device supports enhanced polar codes; or the maximum number of polar code code blocks supported by the terminal device.

[0019] Based on the above technical solution, the terminal device can report its capabilities to the network device, enabling the network device to flexibly determine the first threshold according to the terminal device's indication information and the network side's resource usage. This allows the terminal device to send uplink control information within its capability range, ensuring the terminal device's working performance.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the first uplink control information is the UCI with the lowest priority among the N UCIs.

[0021] In this application, the first uplink control information is the UCI with the lowest priority among the N UCIs. For example, the first uplink control information may be the second part of the channel quality status information (CSI part 2).

[0022] It should be understood that those skilled in the art can flexibly determine the first control information according to the actual situation in this application, without limitation.

[0023] Secondly, an uplink control information transmission method is provided, the method comprising: a network device receiving a physical uplink channel carrying N uplink control information, wherein the first uplink control information and the second uplink control information are concatenated and encoded, or; the network device receiving a physical uplink channel carrying the second uplink control information, wherein the physical uplink control channel does not carry the first uplink control information; wherein N is an integer and greater than 3, the N uplink control information includes the first uplink control information and the second uplink control information, and the second uplink control information has a higher priority than the first uplink control information.

[0024] In conjunction with the second aspect, in some implementations of the second aspect, the physical uplink control channel does not carry the first uplink control information, including: when N is greater than the first threshold, the physical uplink control channel does not carry the first uplink control information.

[0025] In one possible implementation, the physical uplink control channel not carrying the first uplink control information may be that the first uplink control information is discarded, or the network device discards the first uplink control information, or the network device receives the physical uplink channel and obtains the uplink control information carried on the physical uplink channel, which does not include the first uplink control information.

[0026] In conjunction with the second aspect, in some implementations of the second aspect, the first UCI and the second UCI are concatenated and encoded, including: when N is greater than the first threshold, the first uplink control information and the second uplink control information are concatenated and encoded.

[0027] In conjunction with the second aspect, in some implementations of the second aspect, the first threshold is indicated by the network device, or the first threshold is determined based on the capabilities reported by the terminal device, or the first threshold is predefined.

[0028] In conjunction with the second aspect, in some implementations of the second aspect, the capability received by the network device includes at least one of the following: the number of independently coded uplink control information supported by the terminal device is greater than 3; or the maximum number of independently coded uplink control information supported by the terminal device; or the terminal device supports code blocks of more than 6 polar codes; or the terminal device supports enhanced polar codes; or the maximum number of polar code code blocks supported by the terminal device.

[0029] In conjunction with the second aspect, in some implementations of the second aspect, the first uplink control information is the UCI with the lowest priority among the N UCIs.

The embodiments of this application do not limit the type of memory or the way the memory and processor are set.

[0040] It should be understood that the relevant data interaction process, such as sending indication information, can be the process of the processor outputting indication information, and receiving capability information can be the process of the processor receiving input capability information. Specifically, the data output by the processor can be sent to the transmitter, and the input data received by the processor can come from the transceiver.

The embodiments of this application do not limit the number of core network devices, radio access network devices, and terminal devices included in the mobile communication system.

[0063] To facilitate understanding, this application first provides a brief introduction to uplink control information (UCI) and multiplexing.

[0064] Uplink control information includes scheduling requests (SR), hybrid automatic repeat request acknowledgments (HARQ-ACK), and channel state information (CSI). Specifically, CSI can include precoding matrix indicator (PMI), rank indicator (RI), layer indicator (LI), channel quality indicator (CQI), CSI-RS resource indicator (CRI), reference signal received power (RSRP), and signal-to-interference-plus-noise ratio (SINR). Some CSIs can be cascaded, forming either CSI part 1 or CSI part 2. CSI part 1 can include CRI, RI, the wideband CSI of the first transport block, and the subband differential CQI of the first terabyte (TB). The second part of CSI (CSI part 2) may include the wideband CQI, LI, etc. of the second transport block (TB). This application does not specify which CSIs are included in CSI part 1 and CSI part 2. The bit sequence of the above UCI can be represented as follows: ,in, This is the length of the UCI bit sequence. For example, the bit sequence of HARQ-ACK can be represented as... The bit sequence of SR can be represented as The bit sequence of CSI part 1 can be represented as: The bit sequence of CSI part 2 can be represented as: .

[0065] The bit sequences of the above-mentioned UCI can be further concatenated to form the total bit sequence of UCI. Then encoding is performed, which involves processing the total bit sequence of the UCI. For example, the total bit sequence of the UCI... It consists of HARQ-ACK and SR (or can be understood as HARQ-ACK and SR cascaded together), that is, ,in, It is the number of bits in HARQ-ACK. It is the bit sequence of SR. , This refers to the total number of bits, or the payload size. The total bit sequence of UCI. It can also consist of HARQ-ACK, SR, and CSI part 1, or HARQ-ACK and CSI part 1, or only HARQ-ACK, or only CSI part 1, or only CSI part 2, or only SR. It should be understood that concatenating UCI1 and UCI2 means linking the bit sequences of UCI1 and UCI2 together, such as with HARQ-ACK and SR as described above. It should be understood that the total number of bit sequences in the UCI can be 1, 2, 3, or other values.

[0066] When the total bit sequence length of UCI, i.e. When the total bit length A of the UCI is greater than or equal to 12, polar coding is used for the total bit sequence; otherwise, channel coding of small block lengths is used. When polar coding is used, the total bit sequence of the UCI needs to be segmented into code blocks (CBs), and then a cyclic redundancy check (CRC) is added to each CB. Specifically, the total bit sequence of the UCI can be divided into at most two code blocks, with each CB individually having a CRC check added, followed by channel coding (i.e., polar coding). The length A of the total bit sequence of the UCI is less than or equal to 1706.

[0067] Typically, when UCI is carried on the physical uplink control channel (PUCCH), HARQ-ACK, SR, and CSI part 1 are concatenated together to form the total UCI bit sequence. Then encoding is performed, that is, HARQ-ACK, SR, and CSI part 1 are concatenated and then encoded. CSI part 2 is a separate UCI total bit sequence. Then, encoding is performed, i.e., separate encoding. When UCI is carried on the physical uplink shared channel (PUSCH), HARQ-ACK is encoded separately, CSI part 1 is encoded separately, and CSI part 2 is also encoded separately.

[0068] The priority of a UCI (User Information Category) can be related to factors such as the information it contains, the physical uplink channel carrying the UCI, the cell, and its periodicity. Let's take CSI (Content Subject to Search and Retrieval) as an example. Each CSI report can be defined with a priority value. The smaller the value, the higher the priority. Specifically, when the PUSCH carries aperiodic CSI reporting, When the PUSCH carries a semi-persistent CSI report, When the PUCCH carries a semi-persistent CSI report, When the periodic CSI is reported on the PUCCH, If CSI includes RSRP or SINR, then ,otherwise, . It is a serving cell index. It refers to the number of residential communities. It is the index for reporting configuration. This is the maximum number of configurations reported by CSI.

[0069] UCI priorities can also be configured by higher-layer signaling or indicated by downlink control information (DCI). For example, when DCI schedules HARQ-ACK, it can indicate the priority of the HARQ-ACK. If there are only two priorities, it indicates whether the HARQ-ACK is high or low priority.

[0070] UCI priority can also be service-related; for example, the UCI for mMTC has a lower priority than the UCI for eMBB. Additionally, priorities can be defined for UCIs between different PUCCH groups; for instance, the UCI in PUCCH group 0 has a higher priority than the UCI in PUCCH group 1. Similarly, priorities can be defined for UCIs between different base stations, different UEs, or different transmission reception points (TRPs).

[0071] When multiplexing high-priority and low-priority UCIs, this includes carrying high-priority (HP) UCIs and low-priority (LP) UCIs on the PUCCH or PUSCH. For example, the PUCCH carries HP HARQ-ACK, LP HARQ-ACK, and HP SR. The PUSCH carries high-priority HARQ-ACK, low-priority HARQ-ACK, and HP or LP CSIs.

[0072] Currently, to support the multiplexing of high and low priority UCIs together for transmission, encoding high and low priority UCIs separately increases the encoding complexity and cost for user equipment (UE). Therefore, how to better multiplex UCIs has become a technical problem that needs to be solved.

[0073] Figure 2 This is a schematic diagram of the uplink control information transmission method according to an embodiment of this application. Figure 2 The methods include:

[0074] In step S201, the terminal device determines N uplink control information, where N is an integer and greater than 3. The N uplink control information includes first uplink control information and second uplink control information, with the second uplink control information having a higher priority than the first uplink control information.

[0075] In this application, the N uplink control information can be understood as the number of uplink control information to be transmitted by the terminal device, or the number of independently encoded UCI bit sequences. Each of the N UCIs can be HARQ-ACK, CSI part 1, CSI part 2, or SR. Each UCI can also correspond to a priority, and each UCI can independently form a UCI bit sequence for encoding; that is, each of the N UCIs can be encoded independently. For example, if N=4, the 4 UCIs can specifically include a high-priority HARQ-ACK, a low-priority HARQ-ACK, a low-priority CSI part 1, and a low-priority CSI part 2. Alternatively, they can include a high-priority HARQ-ACK, a low-priority HARQ-ACK, a high-priority CSI part 1, and a high-priority CSI part 2. Or, they can include a high-priority HARQ-ACK, a low-priority HARQ-ACK, a high-priority CSI part 1, and a low-priority CSI part 2. Alternatively, the total bit sequence of a UCI can also be composed of multiple UCIs.

[0076] In this application, the first uplink control information can be the UCI with the lowest priority among N UCIs. For example, the first uplink control information can be CSI part 2; or, for another example, the first uplink control information can be a low-priority CSI part 2 or a low-priority CSI part 1. It should be noted that those skilled in the art can flexibly determine the content of the first control information according to the actual situation. In this application, the first uplink control information may include one or more uplink control information.

[0077] For example, the second uplink control information could be HARQ-ACK; or, for another example, it could be CSIpart 1. It should be noted that those skilled in the art can flexibly determine the content of the second control information based on the actual situation.

[0078] When N exceeds the first threshold, the terminal device discards part of the uplink control information or encodes the uplink control information after concatenation.

[0079] The first threshold in this application can also be understood as the number or maximum number of independently encoded uplink control information, or the total number or maximum number of UCI bit sequences (an example of the first threshold). That is, in this application, the first threshold can be the number or maximum number of independently encoded uplink control information, or the total or maximum number of independently encoded UCI bit sequences, or the total number of code blocks encoded by uplink control information, or the total number of code blocks encoded by each independently encoded UCI bit sequence.

[0080] In this application, the first threshold may be indicated by the network device, determined based on the capabilities reported by the terminal device, or predefined.

[0081] In this application, it is assumed that the maximum number of independently encoded uplink control messages supported by the terminal device is Y, i.e., the first threshold is equal to Y, where Y is a positive integer. For example, a low-priority HARQ-ACK is an uplink control message (X1=1) that needs to be encoded separately; a high-priority HARQ-ACK is an uplink control message (X2=1) that needs to be encoded separately; CSI part 1 is an uplink control message (X3=1) that needs to be encoded separately; and CSI part 2 is an uplink control message (X4=1) that needs to be encoded separately.

[0082] In this application, the terminal device can determine N uplink control messages to be sent, where N is an integer greater than 3. That is, the number of uplink control messages to be sent by the terminal device can be greater than 3, but when sending the uplink control messages, the number of sent uplink control messages can be ensured not to exceed the maximum number of independently encoded uplink control messages by using joint encoding or discarding methods. Specifically, X1 + X2 + X3 + X4 <= Y. This allows uplink control messages to be sent within the capabilities of the terminal device, ensuring its operational performance.

[0083] As an example, assume that the terminal device supports a maximum of 4 independently encoded uplink control messages, i.e., the first threshold equals 4. The terminal device can determine the uplink control information as HARQ-ACK and CSI part 1, for example, independently encoded high-priority HARQ-ACK, independently encoded low-priority HARQ-ACK, independently encoded high-priority CSI part 1, and independently encoded low-priority CSI part 1. That is, in this application, the total number of independently encoded UCI bit sequences in the uplink control information determined by the terminal device does not exceed the first threshold Y.

[0084] As an example, the terminal device can first report its capabilities to the network device, such as: the terminal device supports a greater than 4 number of independently encoded uplink control messages, or the maximum number of independently encoded uplink control messages supported by the terminal device. The network device can then indicate a first threshold based on the capabilities reported by the terminal device and / or the network-side resource availability. The terminal device can then determine the uplink control information based on the network device's configuration or scheduling information, ensuring the maximum number of independently encoded uplink control messages.

[0085] The first threshold in this application can also be understood as the number of code blocks of supported UCI, or the maximum number of code blocks of supported UCI (another example of the first threshold).

[0086] For example, assuming the maximum number of code blocks supported by the terminal device is Y, i.e. the first threshold is equal to Y, low-priority HARQ-ACK occupies X1 code blocks, high-priority HARQ-ACK occupies X2 code blocks, CSI part 1 occupies X3 code blocks, and CSI part 2 occupies X4 code blocks, when the terminal device determines the uplink control information, it ensures that the number of code blocks of the uplink control information does not exceed Y, i.e., X1+X2+X3+X4<=Y.

[0087] As an example, assume the terminal device supports a maximum of 5 code blocks. The terminal device can determine that the uplink control information is HARQ-ACK and CSI part 1. For example, the high-priority HARQ-ACK is encoded separately as 2 code blocks, the low-priority HARQ-ACK is encoded separately as 2 code blocks, and CSI part 1 is encoded separately as 1 code block. That is to say, in this application, the number of code blocks for the uplink control information determined by the terminal device does not exceed the maximum number of code blocks, i.e., the first threshold.

[0088] As an example, the terminal device can first report its capabilities to the network device, such as: the terminal device supports code blocks with more than 6 polar codes, or the terminal device supports enhanced polar codes, or the maximum number of polar code code blocks supported by the terminal device. The network device can then instruct the terminal device on a first threshold, i.e., the maximum number of code blocks for uplink control information, based on the capabilities reported by the terminal device and / or the resource availability on the network side. The terminal device can then determine the uplink control information based on the network device's configuration or scheduling information, ensuring that the number of code blocks in the transmitted uplink control information does not exceed the maximum number of code blocks indicated by the network device.

[0089] As an example, assuming the protocol can pre-set the maximum number of code blocks to 6, the terminal device can determine the uplink control information. The terminal device can determine that the uplink control information is HARQ-ACK and CSI part 1. For example, the high-priority HARQ-ACK is 2 code blocks, the low-priority HARQ-ACK is 2 code blocks, and CSI part 1 is 2 code blocks.

[0090] In this application, the terminal device determines N uplink control information within a slot or a sub-slot.

[0091] In this application, the N uplink control messages overlap in the time domain before multiplexing. For example, PUCCH1 carries a high-priority HARQ-ACK, PUCCH2 carries a low-priority HARQ-ACK, and PUSCH carries low-priority CSI part 1 and CSI part 2. Since PUCCH1, PUCCH2, and PUSCH overlap in the time domain, they need to be multiplexed onto the PUSCH for transmission. The same applies if the PUSCH carries high-priority CSI part 1 and CSI part 2.

[0092] Step S202: The terminal device sends a physical uplink channel carrying the N uplink control information to the network device, wherein the first uplink control information and the second uplink control information are concatenated and encoded, or the terminal device discards the first uplink control information and sends a physical uplink channel carrying the second uplink control information.

[0093] In this application, the terminal device can transmit uplink control information containing different priorities on a physical uplink channel.

[0094] In one possible implementation, the terminal device can send a physical uplink channel carrying the N uplink control information messages to the network device, wherein the first uplink control information and the second uplink control information are concatenated and then encoded. Assuming the terminal device can support sending a maximum of 3 uplink control information messages, and the terminal device determines that there can be 4 uplink control information messages to be sent: independently encoded high-priority HARQ-ACK, independently encoded low-priority HARQ-ACK, independently encoded high-priority CSI part 1, and independently encoded low-priority CSI part 1. In this case, the terminal device can concatenate the high-priority CSI part 1 and the low-priority CSI part 1 and then encode them. Assuming the terminal device can support sending a maximum of 6 uplink control information code blocks, and the terminal device determines that there can be 8 uplink control information code blocks to be sent, namely: 2 independently encoded high-priority HARQ-ACK code blocks, 2 independently encoded low-priority HARQ-ACK code blocks, 2 independently encoded high-priority CSI part 1 code blocks, and 2 independently encoded low-priority CSI part 1 code blocks. In this case, the terminal device can concatenate the high-priority CSI part 1 and low-priority CSI part 1 code blocks before encoding. Because the maximum number of code blocks encoded after concatenation is 2, it can be guaranteed that the number of code blocks does not exceed the UE's capacity.

[0095] In one possible implementation, the terminal device can discard the first uplink control information and transmit the physical uplink channel carrying the second uplink control information. For example, suppose the terminal device can support transmitting a maximum of three uplink control information blocks, and the terminal device determines that there are four uplink control information blocks to be transmitted: independently encoded high-priority HARQ-ACK, independently encoded low-priority HARQ-ACK, independently encoded high-priority CSI part 1, and independently encoded low-priority CSI part 1. In this case, the terminal device can discard the low-priority CSI part 1. Alternatively, suppose the terminal device can support transmitting a maximum of six uplink control information blocks, and the terminal device determines that there are eight uplink control information blocks to be transmitted: two independently encoded high-priority HARQ-ACK blocks, two independently encoded low-priority HARQ-ACK blocks, two independently encoded high-priority CSI part 1 blocks, and two independently encoded low-priority CSI part 1 blocks. In this case, the terminal device can discard the low-priority CSI part 1 blocks.

[0096] In one possible implementation, a third UCI can also be carried on the physical uplink channel, with a lower priority than the second UCI. The third UCI is also one of N UCIs.

[0097] In this application, the terminal device discards the first uplink control information and transmits a physical uplink channel carrying the second uplink control information. This can be understood as the terminal device transmitting a physical uplink channel carrying high-priority uplink control information.

[0098] In this application, the terminal device discards the first uplink control information and transmits a physical uplink channel carrying the second uplink control information. This can be understood as the terminal device discarding some low-priority uplink control information and transmitting a physical uplink channel carrying high-priority uplink control information and a physical uplink channel carrying some low-priority uplink control information.

[0099] In this application, the terminal device discards the first uplink control information and transmits the physical uplink channel carrying the second uplink control information. This can be understood as the terminal device also being able to discard or transmit a third uplink control information. The N uplink control information messages also include the third uplink control information.

[0100] In other words, in this application, the terminal device can transmit a physical uplink channel carrying the second uplink control information, but this application does not limit whether the terminal device can also transmit other first uplink control information. This application does not exclude the possibility that the terminal device can discard part of the first uplink control information and transmit information carrying the second uplink control information and some other first uplink control information.

[0101] It should be understood that in this application, the physical uplink channel can be either the physical uplink control channel PUCCH or the physical uplink shared channel PUSCH.

[0102] According to the method provided in this application, uplink control information can be sent within the capabilities of the terminal device, thus ensuring the working performance of the terminal device.

[0103] Figure 3 This is a schematic diagram of the uplink control information transmission method according to an embodiment of this application. Figure 3 The methods include:

[0104] In step S301, the base station sends indication information to the UE. The indication information is used to indicate the uplink control information scheduled by the base station.

[0105] In this application, the indication information can be downlink control information (DCI) or higher-layer configuration information. It should be understood that the indication information corresponding to different UCIs may be different. For example, the base station sends DCI to the UE, and the DCI schedules the transmission of HARQ-ACK. The base station sends configuration information to the UE, scheduling the transmission of periodic CSIs.

[0106] In this application, the indication information may include one or more DCIs, or one or more higher-level configuration information, and the number of uplink control information to be scheduled is N.

[0107] In one possible implementation, the number of uplink control messages indicated by the base station may exceed the UE's processing capacity. It should be understood that this means the total number of UCI bit sequences that need to be independently encoded within the uplink control messages scheduled by the base station exceeds the UE's processing capacity.

[0108] In one possible implementation, the base station indicates that the number of uplink control information code blocks may exceed the UE's processing capacity. It should be understood that this means the total number of code blocks in the uplink control information scheduled by the base station that require independent encoding of the total bit sequence of UCI exceeds the UE's processing capacity.

[0109] In step S302, the UE determines N uplink control information based on the indication information, where N is an integer and greater than 3. The N uplink control information includes the first uplink control information and the second uplink control information, with the second uplink control information having a higher priority than the first uplink control information.

[0110] As an example, assuming the maximum number of uplink control messages with independent coding for a UE is 3, and the indication information indicates that the maximum number of uplink control messages with independent coding is 4, the UE can determine the uplink control messages by concatenating coding or discarding them, so as to ensure that the maximum number of uplink control messages with independent coding does not exceed 3.

[0111] As an example, suppose the maximum number of uplink control information coded by the UE is 5, and the indication information indicates that the maximum number of uplink control information coded by the UE is 4. The UE can determine the uplink control information based on the indication information to ensure that the maximum number of uplink control information coded by the UE does not exceed 4.

[0112] As an example, assuming the UE's processing capacity is 5, and the indication information indicates that the number of uplink control information code blocks is 8, the UE can ensure that the number of uplink control information code blocks does not exceed 5 by concatenating coding or discarding.

[0113] As an example, assuming the UE's processing capacity is 10, and the indication information indicates that the number of uplink control information code blocks is 8, the UE can determine the uplink control information based on the indication information, and the number of uplink control information code blocks does not exceed 8.

[0114] In step S303, the UE sends a physical uplink channel carrying N uplink control information to the base station, wherein the first uplink control information and the second uplink control information are concatenated and encoded, or the UE discards the first uplink control information and sends a physical uplink channel carrying the second uplink control information to the network device.

[0115] For details, please refer to step S202 in method 200, which will not be repeated here.

[0116] In other words, in this application, the UE can send uplink control information with different priorities on a physical uplink channel without exceeding the UE's processing capacity.

[0117] Step S304: The base station receives the physical uplink channel carrying uplink control information.

[0118] In one possible implementation, the base station receives the physical uplink channel carrying uplink control information and also needs to decode it.

[0119] In one possible implementation, the base station can receive a physical uplink channel carrying N uplink control information, wherein the first uplink control information and the second uplink control information are concatenated and encoded.

[0120] In one possible implementation, the base station can receive a physical uplink channel carrying second uplink control information, wherein the physical uplink control channel does not include the first uplink control information. This can also be understood as discarding the first uplink control information.

[0121] In this application, N is an integer greater than 3. The N uplink control information can include first uplink control information and second uplink control information, with the second uplink control information having a higher priority than the first uplink control information.

[0122] The method according to the embodiments of this application enables the transmission of uplink control information within the capabilities of the terminal device, thereby ensuring the working performance of the terminal device.

[0123] Figure 4 This is a schematic diagram of an uplink control information transmission method according to an embodiment of this application. Figure 4 The methods include:

[0124] Step S401: The UE sends capability information to the base station.

[0125] In one possible implementation, the UE reporting capability information may include: the number of independently coded uplink control information that the UE can report is greater than 3, or; the maximum number of independently coded uplink control information that the UE supports.

[0126] In one possible implementation, the capability information reported by the UE may include: the UE may report whether it supports a number of uplink control information blocks greater than or equal to 6, or the UE may report the maximum number of uplink control information blocks it supports, or the UE may report whether it has the capability of enhanced polar coding, etc.

[0127] Step 402: The base station determines the indication information, which is used to indicate the uplink control information scheduled by the base station.

[0128] In one possible implementation, the base station can determine the indication information based on the capabilities reported by the UE and / or the current network resource usage.

[0129] As an example, when a UE reports the number of uplink control messages that support more than or equal to 3 maximum independent codes, for instance, the base station can indicate that the number of uplink control messages with the maximum independent codes is 4 based on the current network resource usage.

[0130] As an example, when the UE reports a maximum number of uplink control messages with a maximum number of independent codes that it supports, for example, the base station can indicate that the maximum number of uplink control messages with a maximum number of independent codes is 5 or 3, depending on the current network resource usage.

[0131] As an example, when a UE reports that it supports a maximum of 6 or more uplink control information blocks, for instance, the base station can indicate that the maximum number of uplink control information blocks is 8 based on the current network resource usage.

[0132] As an example, when the maximum number of uplink control information blocks reported by the UE is 5 or 7, for example, the base station can indicate that the maximum number of uplink control information blocks is 5 based on the current network resource usage.

[0133] As an example, when a UE reports that it has the capability to support enhanced polar coding, for instance, the base station can indicate that the maximum number of uplink control information code blocks is 10, based on the current network resource usage.

[0134] In step S403, the base station sends an indication message to the UE.

[0135] In step S404, the UE determines N uplink control information based on the indication information, where N is an integer and greater than 3. The N uplink control information includes the first uplink control information and the second uplink control information, with the second uplink control information having a higher priority than the first uplink control information.

[0136] For details, please refer to step S302 in method 300, which will not be repeated here.

[0137] Step 405: The UE sends a physical uplink channel carrying N uplink control information to the base station. The first uplink control information and the second uplink control information are concatenated and encoded, or the UE discards the first uplink control information and sends a physical uplink channel carrying the second uplink control information.

[0138] For details, please refer to step S303 in method 300, which will not be repeated here.

[0139] In other words, in this application, the UE can send uplink control information with different priorities on a physical uplink channel without exceeding the UE's processing capacity.

[0140] In step S406, the base station receives the physical uplink channel carrying uplink control information and decodes it.

[0141] For details, please refer to step S304 in method 300, which will not be repeated here.

[0142] The method according to the embodiments of this application enables the transmission of uplink control information within the capabilities of the terminal device, thereby ensuring the working performance of the terminal device.

[0143] Figure 5 This is a schematic diagram of the uplink control information transmission method according to an embodiment of this application. Figure 5 The methods include:

[0144] In step S501, the base station sends indication information to the UE. The indication information is used to indicate the uplink control information scheduled by the base station.

[0145] For details, please refer to step S301 in method 300, which will not be repeated here.

[0146] In step S502, the UE determines N uplink control information based on the indication information, where N is an integer and greater than 3. The N uplink control information includes the first uplink control information and the second uplink control information, with the second uplink control information having a higher priority than the first uplink control information.

[0147] In this embodiment, the UE determines N uplink control information, which can be specifically referred to in step 302 of method 300, and will not be repeated here.

[0148] In some embodiments, step S503a can be performed, in which the UE sends a physical uplink channel carrying N uplink control information to the base station, wherein the first uplink control information and the second uplink control information are concatenated and then encoded.

[0149] As an example, CSI part 1 (an example of second control information) and CSI part 2 (an example of first control information) can be concatenated and then encoded.

[0150] As an example, HARQ-ACK (an example of second control information) and CSI part 1 (an example of first control information) can be concatenated and then encoded.

[0151] As an example, HARQ-ACK (an example of second control information) and CSI part 2 (an example of first control information) can be concatenated and then encoded.

[0152] As an example, UCIs of different priorities can be concatenated and encoded.

[0153] For example, if CSI part 1 has a higher priority than CSI part 2, then the higher-priority CSI part 1 (an example of second control information) and the lower-priority CSI part 2 (an example of first control information) can be concatenated and encoded. Alternatively, if CSI part 1 has a lower priority than CSI part 2, then the higher-priority CSI part 2 (an example of second control information) and the lower-priority CSI part 1 (an example of first control information) can be concatenated and encoded. It should be understood that the above priority ranking is only determined by comparing the first UCI and the second UCI, and does not affect the priority between other UCIs, or the priority comparison between other UCIs and the first or second UCI.

[0154] For example, HARQ-ACK and CSI part 1 have different priorities, or HARQ-ACK and CSI part 2 have different priorities. Both can be concatenated and encoded, similar to CSI part 1 and CSI part 2, and will not be elaborated further.

[0155] It should be understood that the N UCIs can also be sorted according to priority. For example, the priority of UCI 1 is lower than that of UCI 2, the priority of UCI 2 is lower than that of UCI 3, and so on, with the priority of UCI (N-1) being lower than that of UCI N. Therefore, UCI 1 and UCI 2 can be concatenated and encoded.

[0156] It should be understood that UCIs of the same type, but with different priorities, can also be concatenated. For example, all UCI types are HARQ-ACK, but the high-priority HARQ-ACK and low-priority HARQ-ACK can be concatenated. Or, all UCI types are CSI, but the high-priority CSI (e.g., CSI part 2) and low-priority CSI (e.g., CSI part 1) can be jointly encoded.

[0157] It should be noted that the first uplink control information and the second uplink control information described in this embodiment are merely examples and are not intended to limit the scope of the invention. Those skilled in the art can determine the content of the first uplink control information and the second uplink control information based on actual circumstances.

[0158] In this application, there is no limitation on whether to perform concatenated coding for the other UCIs besides the first uplink control information and the second UCI among the N UCIs.

[0159] For example, the third UCI can be jointly encoded with the first UCI and the second UCI, or the third UCI can be jointly encoded with the fourth UCI, or the third UCI can be encoded independently and the fourth UCI can be encoded independently, etc.

[0160] In some embodiments, step S503b can be performed, whereby the UE discards the first uplink control information and transmits a physical uplink channel carrying the second uplink control information.

[0161] As an example, the UE can discard CSI part 2 (an example of the first uplink control information) and transmit the physical uplink channel carrying the second uplink control information. For example, the UE can discard the code block of CSI part 2. For example, suppose the terminal device determines that there are four uplink control information blocks to be transmitted: independently encoded high-priority HARQ-ACK, independently encoded low-priority HARQ-ACK, independently encoded CSI part 1, and independently encoded CSI part 2. In this case, the terminal device can discard CSI part 2 (because it has the lowest priority). Suppose the terminal device determines that there are eight code blocks of uplink control information to be transmitted: two independently encoded high-priority HARQ-ACK blocks, two independently encoded low-priority HARQ-ACK blocks, two independently encoded CSI part 1 blocks, and two independently encoded CSI part 2 blocks. In this case, the terminal device can discard the code block of CSI part 2.

[0162] It should be noted that in this embodiment, the first uplink control information is CSI part 2 as an example, and no limitations are imposed. Those skilled in the art can predefine the content of the first uplink control information to be discarded by the UE according to the actual situation. For example, the first uplink control information can be low-priority CSI part 1 and low-priority CSI part 2. It can also be discarded according to priority order.

[0163] It should be noted that steps S503a and S503b in this application are two parallel implementations. In actual operation, steps S503a and S503b do not need to be executed simultaneously.

[0164] Step S504: The base station receives the physical uplink channel carrying uplink control information.

[0165] For details, please refer to step S304 in 300, which will not be repeated here.

[0166] The method according to the embodiments of this application enables the transmission of uplink control information within the capabilities of the terminal device, thereby ensuring the working performance of the terminal device.

[0167] Method 600 is an embodiment of the uplink control information transmission method provided in this application. Method 600 includes:

[0168] Step S601: The base station sends indication information to the UE. The indication information is used to indicate the uplink control information scheduled by the base station.

[0169] For details, please refer to step S301 in method 300, which will not be repeated here.

[0170] In step S602, the UE determines N uplink control information based on the indication information, where N is an integer and greater than 3. The N uplink control information includes the first uplink control information and the second uplink control information, with the second uplink control information having a higher priority than the first uplink control information.

[0171] In this embodiment, the UE determines N uplink control information, which can be specifically referred to in step 302 of method 300, and will not be repeated here.

[0172] In some embodiments, step 603a can be performed, in which the UE sends a physical uplink channel carrying N uplink control information to the base station, wherein the first uplink control information and the second uplink control information are concatenated and then encoded.

[0173] In one possible implementation, when N is greater than a first threshold, the first UCI and the second UCI can be concatenated and then encoded.

[0174] For example, when the number N of uplink control information to be transmitted exceeds the maximum number of independently coded uplink control information (i.e., the first threshold), joint coding can be used. Assuming the maximum number of independently coded uplink control information for the UE is 3, and the number of independently coded uplink control information to be transmitted is 4, the UE can use joint coding.

[0175] For example, assume that the number of uplink control messages independently encoded by low-priority HARQ-ACK is X1, the number of uplink control messages independently encoded by high-priority HARQ-ACK is X2, the number of uplink control messages independently encoded by CSI part 1 is X3, and the number of uplink control messages independently encoded by CSI part 2 is X4. As an example, if X1+X2+X3+X4 > the maximum number of independently encoded uplink control messages indicated by the base station, or if X1+X2+X3+X4 > the UE's processing capacity, the UE can encode CSI part 2 in conjunction with CSI part 1, or concatenate CSI part 2 with HARQ-ACK.

[0176] As another example, the UE can encode uplink control information exceeding its capabilities by concatenating it with other uplink control information. See also Figure 6 ,exist Figure 6 Since the low-priority HARQ-ACK exceeds the UE's processing capacity, the UE can encode the low-priority HARQ-ACK by concatenating it with CSI part 1, or by concatenating it with CSI part 2. This will not be elaborated further.

[0177] In one possible implementation, when the total number of code blocks is greater than the second threshold, the first UCI and the second UCI can be concatenated and encoded.

[0178] For example, when the number of code blocks for uplink control information to be transmitted exceeds the maximum number of code blocks, the UE can perform joint encoding. Assuming the maximum number of code blocks for the UE is 6, and the number of code blocks for uplink control information to be transmitted is 8, the UE can perform joint encoding.

[0179] For example, assume that low-priority HARQ-ACK occupies X1 code blocks, high-priority HARQ-ACK occupies X2 code blocks, CSI part 1 occupies X3 code blocks, and CSI part 2 occupies X4 code blocks. As an example, if X1+X2+X3+X4 > the maximum number of uplink control information code blocks indicated by the base station, or if X1+X2+X3+X4 > the UE's processing capacity, the UE can encode CSI part 2 together with CSI part 1, or CSI part 2 together with HARQ-ACK. As another example, the UE can encode UCIs exceeding its capacity together with other UCIs.

[0180] See also Figure 6 ,exist Figure 6 Since the low-priority HARQ-ACK exceeds the UE's processing capacity, the UE can encode the low-priority HARQ-ACK together with CSI part 1, or encode the low-priority HARQ-ACK together with CSI part 2. This will not be elaborated further.

[0181] In some embodiments, step S603b can be performed, in which the UE discards the first uplink control information and transmits a physical uplink channel carrying the second uplink control information.

[0182] In one possible implementation, when N is greater than a first threshold, the UE discards the first uplink control information.

[0183] For example, when the number N of uplink control information to be transmitted exceeds the maximum number of independently encoded uplink control information (i.e., the first threshold), the UE can discard the first uplink control information. Assuming the UE's maximum number of independently encoded uplink control information is 3, and the number of uplink control information to be transmitted is 4, the UE can discard the first uplink control information.

[0184] For example, assume the number of independently encoded uplink control messages in low-priority HARQ-ACK is X1, the number of independently encoded uplink control messages in high-priority HARQ-ACK is X2, the number of independently encoded uplink control messages in CSI part 1 is X3, and the number of independently encoded uplink control messages in CSI part 2 is X4. As an example, if the number of independently encoded uplink control messages to be transmitted (X1+X2+X3+X4) > 3, the UE can discard CSI part 2; if the number of independently encoded uplink control messages (X1+X2+X3+X4) <= 3, the UE does not need to perform a discard operation. As another example, if the number of uplink control messages to be transmitted (X1+X2+X3+X4) > the UE's processing capacity, the UE can directly discard the independently encoded uplink control messages in CSI part 2; if the number of independently encoded uplink control messages indicated by the base station does not exceed the UE's processing capacity, the UE does not need to perform a discard operation.

[0185] For example, such as Figure 7 As shown, the base station can indicate that there is one independently encoded uplink control message for high-priority HARQ-ACK, one independently encoded uplink control message for high-priority CSI part 1 code block, one independently encoded uplink control message for high-priority CSI part 2 code block, and one independently encoded uplink control message for low-priority HARQ-ACK. In this case, the UE can discard independently encoded uplink control information exceeding its own capacity, for example, discarding the low-priority HARQ-ACK. This can also be understood as canceling the transmission of the low-priority HARQ-ACK at this time.

[0186] In one possible implementation, the UE discards the first uplink control information when the total number of code blocks exceeds a second threshold. For example, the UE can discard the first uplink control information when the number of code blocks for uplink control information to be transmitted exceeds the maximum number of code blocks. Assuming the UE's maximum number of code blocks is 6, and the number of code blocks for uplink control information to be transmitted is 8, the UE can discard the first uplink control information.

[0187] For example, assume that low-priority HARQ-ACK occupies X1 code blocks, high-priority HARQ-ACK occupies X2 code blocks, CSI part 1 occupies X3 code blocks, and CSI part 2 occupies X4 code blocks. As an example, if the number of independently encoded uplink control information code blocks X1+X2+X3+X4 > 6, the UE can discard the CSI part 2 code blocks; if the number of independently encoded uplink control information code blocks X1+X2+X3+X4 <= 6, the UE does not need to perform a discard operation. As another example, if the number of code blocks indicated by the base station X1+X2+X3+X4 > the UE's processing capacity, the UE can directly discard the CSI part 2 code blocks; if the number of code blocks does not exceed the UE's processing capacity, the UE does not need to perform a discard operation.

[0188] For example, such as Figure 7 As shown, there are 2 high-priority HARQ-ACK blocks, 1 high-priority CSI part 1 block, 2 high-priority CSI part 2 blocks, and 2 low-priority HARQ-ACK blocks. At this point, the UE can discard blocks exceeding its capacity, for example, discarding one block of the low-priority HARQ-ACK. This can also be understood as canceling the transmission of the low-priority HARQ-ACK.

[0189] It should be understood that, since the number of code blocks for uplink control information is related to the number of bits in the total bit sequence of UCI, the UCI payload can be split into at most 2 code blocks.

[0190] In other words, in this application, the UE can send uplink control information with different priorities on a physical uplink channel without exceeding the UE's processing capacity.

[0191] It should be noted that steps S603a and S603b in this application are two parallel implementations. In actual operation, steps S603a and S603b do not need to be executed simultaneously.

[0192] Step S604: The base station receives the physical uplink channel carrying uplink control information.

[0193] For details, please refer to step S304 in 300, which will not be repeated here.

[0194] The method according to the embodiments of this application enables the transmission of uplink control information within the capabilities of the terminal device, thereby ensuring the working performance of the terminal device.

[0195] Method 700 is an embodiment of the uplink control information transmission method provided in this application. The technical solution of this embodiment is as follows:

[0196] When UCIs of the same priority are multiplexed and transmitted on PUCCH or PUSCH, the timing must be satisfied, for example, the following first timing and second timing must be satisfied.

[0197] It should be understood that the timeline is the interval between the DCI and symbol S0, where symbol S0 is the first symbol of the earliest channel in the overlapping channels. The timeline can also be the interval between the Physical Downlink Shared Channel (PDSCH) and symbol S0.

[0198] If the overlapping channels include PUSCH, then the second timing sequence can be:

[0199]

[0200] Here, i represents the i-th PUSCH. It can be understood that in a set of overlapping channels, there can be multiple PUSCHs, and i is the index of the PUSCH. Specifically... The formula is as follows:

[0201]

[0202] Where N2 is the PUSCH preparation time, in units of orthogonal frequency division multiplexing (OFDM) symbols; These are parameters related to the demodulation reference signal (DMRS). If the first symbol of the PUSCH contains only DMRS, then... The value of is 0, otherwise The value of is 1. κ is a constant, typically equal to 64. μ is the subcarrier spacing index. T C It is a time unit, such as T C It can meet the following requirements:

[0203] ;

[0204] in, .

[0205] T switch This is the uplink switching gap; if the DCI triggers a BWP handover, This is the bandwidth part (BWP) switch time; otherwise, it equals 0. `max()` performs a maximum value operation. In this application's embodiments, unless otherwise specified, the symbols may refer to abbreviations of OFDM symbols.

[0206] If the overlapping channels do not include PUSCH, then the second timing sequence can be:

[0207]

[0208] The first time sequence is:

[0209]

[0210]

[0211] Where i represents the i-th PDSCH, and N1 is the PDSCH processing time. The value of is related to the PDSCH mapping method, the length of PDSCH, and the processing capability of the UE.

[0212] When UCIs of different priorities are multiplexed and transmitted on PUCCH or PUSCH, the timing must meet the requirements of the third and fourth timing sequences. Specifically, the third timing sequence must be greater than the first timing sequence, or the fourth timing sequence must be greater than the second timing sequence.

[0213] It should be understood that "the third time sequence is greater than the first time sequence" means that the duration of the third time sequence is greater than that of the first time sequence, or that the time length of the third time sequence is greater than that of the first time sequence.

[0214] It should be understood that "the fourth time sequence is greater than the second time sequence" means that the duration of the fourth time sequence is greater than that of the second time sequence, or that the time length of the fourth time sequence is greater than that of the second time sequence.

[0215] In one possible implementation, the third timing sequence may be greater than the first timing sequence, or the fourth timing sequence may be greater than the second timing sequence, when the total number of bit sequences in the UCI is greater than 3, or when the total number of code blocks in the UCI is greater than 6.

[0216] If the overlapping channels include PUSCH, then the fourth timing sequence can be:

[0217]

[0218]

[0219] Where X is greater than 1, and can be 2 or 3, representing X symbols, where X is an integer.

[0220] If the overlapping channels do not include PUSCH, then the fourth timing sequence can be:

[0221]

[0222] Where Y is greater than 1, and can be 2 or 3, representing Y symbols, where Y is an integer.

[0223] The third time sequence is:

[0224]

[0225]

[0226] Where Z is greater than 1, and can be 2 or 3, representing Z symbols, and Z is an integer.

[0227] As can be seen from the above, the number of symbols increases when multiplexing with different priorities. Therefore, as the number of code blocks continues to increase, the processing time will also need to increase further, for example, by adding 1, 2, or 3 more symbols.

[0228] In other words, this application also considers the impact of increasing the number of uplink control information code blocks on the UE's processing time. When the number of uplink control information code blocks or the quantity of uplink control information increases, the processing time can be increased by increasing the number of symbols, thereby enabling the transmission of uplink control information within the capabilities of the terminal device and ensuring the working performance of the terminal device.

[0229] As an example, suppose the maximum number of uplink control information code blocks supported by the UE is 6. If the number of uplink control information code blocks to be transmitted by the UE is greater than 6, 1, 2 or 3 symbols can be added to increase the processing time and ensure the working performance of the UE.

[0230] As an example, suppose the UE supports 3 independently encoded uplink control messages. If the number of uplink control messages to be sent by the UE is greater than 3, 1, 2 or 3 symbols can be added to increase the processing time and ensure the working performance of the UE.

[0231] That is, in this application, the terminal device can determine N uplink control information, where N is an integer and greater than 3. The N uplink control information includes first uplink control information and second uplink control information, and the second uplink control information has a higher priority than the first uplink control information. When N is greater than a first threshold, the processing time or multiplexing processing time of the terminal device will increase, for example, by increasing the number of symbols, so that the terminal device can complete multiplexing.
