Description
Technical Field
The present disclosure relates to the field of wireless communications technologies, and in particular, to a multiplexing method, a device, a terminal, a network side device, and a storage medium.
Background
In the communication system, when a physical uplink control channel (Physical Uplink Control Channel, PUCCH) of High Priority (HP) and a PUCCH of Low Priority (LP) overlap in the time domain, the terminal may discard the physical channel of Low Priority and transmit only the physical channel of High Priority.
To reduce the impact of discarding low priority physical channels, physical channels of different priorities may be multiplexed. For the case where the HP uplink control information (Uplink Control Information, UCI) and the LP UCI are multiplexed to one PUCCH and the total number of bits is greater than 2, the HP UCI and the LP UCI are independently encoded, and the format of the PUCCH is required to support multiple encoding links.
However, in the formats that can be used for carrying PUCCHs exceeding 2 bits UCI, not all the formats of PUCCHs support multiple coding links, and when the selected format of the PUCCH does not support multiple coding links, the HP UCI and the LP UCI cannot be independently coded and multiplexed onto the PUCCH format.

Detailed Description
In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant background knowledge is first presented below.
(1) Multiplexing of HP HARQ-ACK and LP HARQ-ACK;
for better multiplexing performance, it has been determined that independent coding is used for both the HP HARQ-ACK and the LP HARQ-ACK for the case where the HP hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat request-ACKnowledgment, HARQ-ACK) and the LP HARQ-ACK are multiplexed to one PUCCH and the total number of bits is greater than 2. The PUCCH Format (PF) for carrying UCI over 2 bits in NR includes PF 2/3/4, as shown in table 1, where PF2 supports only one coding chain (coding chain) in Rel-15/16, so supporting independent encoding of HP HARQ-ACK and LP HARQ-ACK on PF2 may have an effect on the transmission and reception algorithms and implementations of the terminal and the base station, and thus whether and how UCI multiplexing with different priorities is supported on PF2 has no conclusion.
PF2 is the only one short PUCCH format among PUCCH formats capable of carrying more than 2 bits, the number of symbols of the PUCCH is 1 or 2 symbols, and PF3/4 is at least 4 symbols, so PF2 is very important for URLLC traffic with higher delay requirements.
TABLE 1
| PUCCH format | Occupying the number of OFDM symbols | Bit number of bearer |
| 0 | 1–2 | ≤2 |
| 1 | 4–14 | ≤2 |
| 2 | 1–2 | >2 |
| 3 | 4–14 | >2 |
| 4 | 4–14 | >2 |
(2) Multiplexing on PUCCH for different priority UCI reaches the following conclusion:
1-bit HP HARQ-ACK and 1-bit LP HARQ-ACK are treated as 2-bit HP HARQ-ACK when multiplexed on the PUCCH;
for the case where the HP HARQ-ACK and the LP HARQ-ACK are multiplexed to one PUCCH and the total bit number is greater than 2, the HP HARQ-ACK and the LP HARQ-ACK are independently encoded;
for the overlapping processing of PUCCHs of different priorities, overlapping between PUCCHs of the same priority is processed first and overlapping between PUCCHs of different priorities is processed second.
In order to overcome the above drawbacks, embodiments of the present application provide a solution capable of determining a target coding manner matched with a format of a target PUCCH, and coding UCI with different priorities, and supporting multiplexing UCI with different priorities to PUCCH on each PF.

For example, in the case where the format of the target PUCCH is PF3, the terminal may determine a target coding scheme matching the PF3, for example, may be independent coding.
For example, in the case where the format of the target PUCCH is PF4, the terminal may determine a target coding scheme matching the PF4, for example, may be independent coding.

Step 103, coding the first control information and the second control information based on the target coding mode to obtain target coding information;
specifically, after determining the target coding manner, the terminal may code the first control information and the second control information based on the target coding manner, so as to obtain target coding information, and further may send the target coding information to the network side device on the PUCCH.
For example, in the case that the target coding mode is determined to be independent coding, the terminal may independently code the first control information and the second control information, so as to obtain target coding information, where the target coding information includes the first control information that is independently coded and the second control information that is independently coded, and the first control information that is independently coded and the second control information that is independently coded may be multiplexed on the PUCCH and sent to the network side device.
For example, in the case that the target coding mode is determined to be joint coding, the terminal may perform cascade connection on the first control information and the second control information and then perform coding together to obtain the target coding information, where the joint coding information is carried on the PUCCH and sent to the network side device.
The above examples are merely illustrative of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
It may be understood that the format of the target PUCCH may be any one of PUCCH formats such as PF2, PF3, and PF4, after determining the format of the target PUCCH, the terminal may determine a target coding mode matching the format of the target PUCCH, and since the first control information and the second control information may be UCI with different priorities, the terminal may encode UCI with different priorities based on the target coding mode to obtain the target coding information, and further may send the target coding information on the PUCCH, and ensure that the adopted coding mode is the coding mode supported by the PF, so as to enable multiplexing of UCI with different priorities to the PUCCH supported on each PF.
According to the multiplexing method provided by the embodiment of the application, under the condition that the time domain resources of the PUCCH carrying the first control information and the time domain resources of the PUCCH carrying the second control information are coincident, the target coding mode is determined based on the format of the target PUCCH, the first control information and the second control information are coded based on the coding mode supported by the format of the target PUCCH, and UCI multiplexing transmission with different priorities is supported on the PUCCH by adopting the coding mode supported by the format when the target PUCCH is ensured to be in any format.
Optionally, the determining a target coding manner matched with the format of the target PUCCH includes:
and when the format of the target PUCCH is a physical uplink control channel format PF3 or PF4, determining that the target coding mode is independent coding, wherein the independent coding is a coding mode for independently coding the first control information and the second control information.
Specifically, the target coding mode corresponding to the format PF3 of the target PUCCH is independent coding.
Specifically, the target coding mode corresponding to the format PF4 of the target PUCCH is independent coding.
Specifically, after determining the format of the target PUCCH, if the format of the target PUCCH is PF3, the terminal may determine the target coding mode as an independent coding, where the independent coding may be a coding mode in which the first control information and the second control information are independently coded.
Specifically, after determining the format of the target PUCCH, if the format of the target PUCCH is PF4, the terminal may determine the target coding mode as an independent coding, where the independent coding may be a coding mode in which the first control information and the second control information are independently coded.
For example, the first control information may be HP UCI, the second control information may be LP UCI, and after determining that the format of the target PUCCH is PF3, the terminal may determine that the target coding mode is independent coding, and further the terminal may independently code the HP UCI and the LP UCI.
For example, the first control information may be LP UCI, the second control information may be HP UCI, and after determining that the format of the target PUCCH is PF4, the terminal may determine that the target coding mode is independent coding, and further the terminal may independently code the LP UCI and the HP UCI.
The above examples are merely illustrative of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
It may be appreciated that, since PF3 and PF4 may support multiple coding links, if the format of the target PUCCH is PF3 or PF4, the terminal may independently code the first control information and the second control information, and the independently coded first control information and the independently coded second control information may be multiplexed on the PUCCH and sent to the network side device.
Therefore, when the format of the target PUCCH is PF3 or PF4, the terminal may determine a target coding manner, that is, independent coding, that is matched with the format of the target PUCCH, and may further encode the first control information and the second control information based on the independent coding, to obtain the target coding information, and may further send the target coding information on the target PUCCH, and since the first control information and the second control information may be UCI with different priorities, multiplexing UCI with different priorities to the PUCCH may be supported on PF3 or PF 4.

The above examples are merely illustrative of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
Alternatively, in the case where the target coding mode is determined to be the first joint coding, the terminal may perform the coding together after concatenating the first control information and the second control information in the order in which the first control information is preceding and the second control information is following.
Alternatively, in the case where the target coding mode is determined to be the first joint coding, the terminal may perform the coding together after concatenating the first control information and the second control information in order of the preceding second control information and the following first control information.
Alternatively, in the case where the target coding mode is determined to be the first joint coding, the terminal may perform the coding together after concatenating the first control information and the second control information in order of the high priority control information before and the low priority control information after.
For example, the first control information may be an HP UCI and the second control information may be an LP UCI, and the terminal may encode the first control information and the second control information together after concatenating the first control information and the second control information in order of the first control information before and the second control information after the first control information is higher in priority than the second control information.
For example, the first control information may be LP UCI and the second control information may be HP UCI, and the terminal may encode the first control information and the second control information together after concatenating the first control information and the second control information in order of the second control information before and the first control information after the first control information is lower in priority than the second control information.
The above examples are merely illustrative of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
It may be appreciated that, since PF2 may support one coding link, if the format of the target PUCCH is PF2, the terminal may perform concatenation and then perform coding on the first control information and the second control information together.
Therefore, when the format of the target PUCCH is PF2, the terminal may determine a target coding manner, that is, the first joint coding, that is matched with the format of the target PUCCH, and may further encode the first control information and the second control information based on the first joint coding, to obtain target coding information, and may further send the target coding information on the target PUCCH, and since the first control information and the second control information may be UCI with different priorities, multiplexing UCI with different priorities to the PUCCH may be supported on PF 2.
Optionally, after the encoding the first control information and the second control information based on the target encoding mode to obtain target encoding information, the method further includes:
and transmitting the target coding information of the first control information and the second control information on the target PUCCH.
Specifically, after the first control information and the second control information are encoded, the terminal may obtain the encoded target encoding information, and may further send the target encoding information of the first control information and the second control information on the target PUCCH.
For example, when the target coding mode is PF3, the terminal may independently code the first control information and the second control information, and further obtain the coded target coding information, and further may transmit the target coding information of the first control information and the second control information on the target PUCCH.
For example, when the target coding mode is PF4, the terminal may independently code the first control information and the second control information, and further obtain the coded target coding information, and further may transmit the target coding information of the first control information and the second control information on the target PUCCH.
For example, in the case where the target coding mode is PF2, the terminal may perform concatenation on the first control information and the second control information and then perform coding together, so as to obtain coded target coding information, and further may transmit the target coding information of the first control information and the second control information on the target PUCCH.
The above examples are merely illustrative of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
It may be appreciated that, after the terminal transmits the target coding information of the first control information and the second control information on the target PUCCH, the network side device may receive the target coding information of the first control information and the second control information on the target PUCCH.
Therefore, after the terminal obtains the target coding information, the terminal can send the target coding information of the first control information and the second control information on the target PUCCH, so that the network side equipment receives the target coding information, and multiplexing the first control information and the second control information to the target PUCCH is realized.
Optionally, the determining a target coding manner matched with the format of the target PUCCH includes:
and determining that the target coding mode is a first joint coding or a second joint coding when the format of the target PUCCH is PF2, wherein the first joint coding is a coding mode of coding the first control information and the second control information together after being cascaded, and the second joint coding is a coding mode of discarding the second control information and only coding the first control information.
Specifically, in the case that the format of the target PUCCH is PF2, it may be determined that the target coding manner is first joint coding, that is, the first control information and the second control information are coded together after being concatenated;
specifically, in the case that the format of the target PUCCH is PF2, it may be determined that the target coding mode is second joint coding, that is, the second control information is discarded, and only the first control information is coded;
for example, in the case that the format of the target PUCCH is PF2, the first control information may be HP UCI, and the second control information may be LP UCI, so that the terminal may determine that the target coding mode is the first joint coding, and may further perform coding after cascade connection of the HP UCI and the LP UCI, so as to obtain coded target coding information.
For example, in the case that the format of the target PUCCH is PF2, the first control information may be LP UCI, and the second control information may be HP UCI, so that the terminal may determine that the target coding mode is the first joint coding, and may further perform coding after cascade connection of the LP UCI and the HP UCI, so as to obtain target coding information including the LP UCI and the HP UCI.
For example, in the case that the format of the target PUCCH is PF2, the first control information may be HP UCI, and the second control information may be LP UCI, so that the terminal may determine that the target coding mode is the second joint coding, and may discard the LP UCI, and only encode the HP UCI, to obtain the encoded target coding information.
Alternatively, the second control information is discarded, and only the first control information is encoded, which can be regarded as a joint encoding of the first control information and the second control information including 0-bit content.
For example, in the case that the format of the target PUCCH is PF2, the first control information may be HP UCI, and the second control information may be LP UCI, so that the terminal may determine that the target coding mode is second joint coding, and may further jointly code the HP UCI and the LP UCI including 0-bit content.
The above examples are merely illustrative of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
Therefore, the terminal can determine that the target coding mode is the first joint coding or the second joint coding under the condition that the format of the target PUCCH is PF2, and can support multiple service scenarios because the first control information and the second control information can be coded by one coding mode of multiple coding modes.
