The specific parameters include at least one of a starting symbol of the at least three non-overlapping PUCCHs, a priority of content carried by the at least three non-overlapping PUCCHs, and a type of the at least three non-overlapping PUCCHs.

For example, the specific parameters include: starting symbols of the at least three non-overlapping PUCCHs; the priorities of the at least three non-overlapping PUCCHs carrying content; or, a type of the at least three non-overlapping PUCCHs. As another example, the specific parameters include: starting symbols and priorities of carrying contents of the at least three non-overlapping PUCCHs; the priorities and types of the at least three non-overlapping PUCCHs carrying content; or, starting symbols and types of the at least three non-overlapping PUCCHs. As another example, the specific parameters include: a starting symbol, priority of carrying content, and type of the at least three non-overlapping PUCCHs.

It should be noted that the specific parameters mentioned in the embodiments of the present specification are general descriptions of at least one of a starting symbol, a priority of a bearer content, and a type of at least three non-overlapping PUCCHs in one slot, and do not represent other specific meanings.

For the types of the at least three non-overlapping PUCCHs, the types can be classified according to different carrying contents: HARQ-ACK/NACK PUCCH, SR PUCCH, and CSI PUCCH; it can also be divided into dynamically scheduled (dynamically scheduled) PUCCH and configured (configured) PUCCH, etc.

Optionally, the at least three non-overlapping PUCCHs at least include a HARQ-ACK/NACK PUCCH or a SR PUCCH.

In the PUCCH transmission method provided in the embodiments of this specification, if there are at least three non-overlapping PUCCHs in one slot, the terminal device can determine the PUCCH to be transmitted based on specific parameters of the at least three non-overlapping PUCCHs, which solves the problem that the terminal device cannot determine the PUCCH to be transmitted, avoids the transmission problem caused by inconsistency in understanding of PUCCH transmission between the terminal device and the network device, and improves effectiveness of communication.

In the transmission method of the PUCCH provided in the embodiment of the present specification, after determining the PUCCH to be transmitted, the terminal device may send the determined PUCCH and the UCI thereof; similarly, the network device may determine the PUCCH to be transmitted by using the PUCCH transmission method, and then receive and decode UCI on the determined PUCCH resource.

In order to describe the transmission method of the PUCCH provided in the present application in detail, the following description will be made with reference to several specific embodiments.

The first embodiment is as follows: the specific parameters include starting symbols of at least three non-overlapping PUCCHs within one slot.

If there are at least three non-overlapping PUCCHs within one slot, two PUCCHs with the earliest starting symbol are transmitted based on the positions of the starting symbols of the at least three non-overlapping PUCCHs, and at least one of the two PUCCHs transmitted is a short PUCCH.

Specifically, in this embodiment, based on the positions of the starting symbols of the at least three non-overlapping PUCCHs, a PUCCH with the earliest starting symbol and a first PUCCH after the position of the starting symbol of the first PUCCH are determined as PUCCHs to be transmitted, where the PUCCH with the earliest starting symbol is in a short format.

Alternatively, the first and second electrodes may be,

specifically, in this embodiment, based on the positions of the starting symbols of the at least three non-overlapping PUCCHs, a PUCCH with the earliest starting symbol and a first short format PUCCH after the position of the PUCCH with the earliest starting symbol are determined as the PUCCH to be transmitted, where the PUCCH with the earliest starting symbol is a long format.

For example, referring to fig. 2, there are four PUCCHs to be transmitted in one slot, which are long format HARQ-ACK/NACK PUCCHs respectively; a long-format SR PUCCH; a short-format CSI1PUCCH and a short-format CSI2 PUCCH.

As shown in fig. 2, after sorting according to the sequence position of the start symbol: HARQ-ACK/NACK PUCCH, SR PUCCH, CSI2 PUCCH, CSI1 PUCCH.

The terminal equipment selects two PUCCHs with the earliest starting symbols, and at least one PUCCH is short-format PUCCH, so that HARQ-ACK/NACK PUCCH and CSI2 PUCCH can be transmitted, and SR PUCCH and CSI1PUCCH and UCI corresponding to the PUCCH and the CSI1PUCCH can be discarded.

For the short PUCCH and the long PUCCH, or referred to as short format PUCCH and long format PUCCH, referred to in various embodiments of the present specification, see table 1:

table 1PUCCH format (format)

PUCCH format	OFDM symbol length	Number of bits
			0	1–2	≤2
1	4–14	>2
			2	1–2	≤2
3	4–14	>2
			4	4–14	>2

As can be seen from table 1, the PUCCH supports 5 formats of format 0-format 4, where format 0 and format 2 belong to the short format PUCCH; format 1, format 3, and format 4 belong to a long format PUCCH.

The HARQ-ACK/NACK PUCCH, the CSI PUCCH, and the SR PUCCH mentioned in the embodiments of the present specification respectively denote a PUCCH for transmitting HARQ-ACK/NACK, a PUCCH for transmitting CSI, a PUCCH for transmitting SR, and so on.

Example two: the specific parameters include starting symbols of at least three non-overlapping PUCCHs within one slot.

If at least three non-overlapping PUCCHs exist in one slot, determining two PUCCHs with the earliest starting symbol based on the positions of the starting symbols of the at least three non-overlapping PUCCHs;

and if at least one of the two PUCCHs with the earliest starting symbol is in a short format, taking the two PUCCHs with the earliest starting symbol as the PUCCH for transmission.

Alternatively, the first and second electrodes may be,

and if the two PUCCHs with the earliest starting symbols are both in long format, selecting one of the two long format PUCCHs as the PUCCH for transmission.

For example, if both PUCCHs with the earliest start symbol are in long format (format 1/3/4), the first of the two PUCCHs with the earliest start symbol is transmitted (in the precedence order of the start symbol positions), and the last of the two PUCCHs with the earliest start symbol (the second) is discarded.

Alternatively, the first and second electrodes may be,

if both PUCCHs with earliest start symbols are long format (format 1/3/4), the second of the two PUCCHs with earliest start symbols is transmitted and the first of the two PUCCHs with earliest start symbols is discarded.

Example three: the specific parameter includes a priority of at least three non-overlapping PUCCH bearer contents within one slot.

If at least three non-overlapping PUCCHs exist in one time slot, based on the priority of the content carried by the at least three non-overlapping PUCCHs, determining the PUCCH with the highest priority and the first PUCCH after the PUCCH with the highest priority (in the sequence from the top to the bottom of the priority) as the PUCCH for transmission, wherein the PUCCH with the highest priority is in a short format.

Alternatively, the first and second electrodes may be,

and determining the PUCCH with the highest priority and the first short-format PUCCH after the PUCCH with the highest priority (in the sequence from the top to the bottom of the priorities) as the PUCCH for transmission based on the priorities of the at least three non-overlapping PUCCHs carrying contents, wherein the PUCCH with the highest priority is a long-format PUCCH.

The at least three non-overlapping PUCCHs include HARQ-ACK/NACK PUCCH, SR PUCCH, and CSI PUCCH.

Optionally, the priority of the HARQ-ACK/NACK PUCCH is higher than that of the SR PUCCH; the priority of SR PUCCH is higher than that of CSI PUCCH. For the priorities of different CSI PUCCHs, reference may be made to existing protocol specifications, for example, the priority of CSI1PUCCH is higher than that of CSI2 PUCCH, and the priority of CSI2 PUCCH is higher than that of CSI3 PUCCH.

Optionally, the priority of the SR PUCCH is higher than the priority of the HARQ-ACK/NACK PUCCH; the priority of the HARQ-ACK/NACK PUCCH is higher than that of the CSI PUCCH. For the priorities of different CSI PUCCHs, reference may be made to existing protocol specifications, for example, the priority of CSI1PUCCH is higher than that of CSI2 PUCCH, and the priority of CSI2 PUCCH is higher than that of CSI3 PUCCH.

For example, as shown in fig. 2, there are four PUCCHs to be transmitted in one slot, which are long-format HARQ-ACK/NACK PUCCHs respectively; a long-format SR PUCCH; a short-format CSI1PUCCH and a short-format CSI2 PUCCH. Wherein the priority of the CSI1PUCCH is higher than that of the CSI2 PUCCH.

The priority order of the four non-overlapping PUCCH bearer contents is as follows: HARQ-ACK/NACK PUCCH > SR PUCCH > CSI1PUCCH > CSI2 PUCCH. The terminal equipment selects two PUCCHs with the highest bearing content priority, and at least one PUCCH is short-format PUCCH, so that HARQ-ACK/NACK PUCCH and CSI1PUCCH can be transmitted, and SR PUCCH and CSI2 PUCCH and UCI corresponding to the PUCCH and the CSI2 PUCCH can be discarded.

It should be noted that, in the third embodiment, if at least three non-overlapping PUCCHs in one slot include a combined PUCCH, and the combined PUCCH is formed by combining multiple UCIs with different contents, the priority of the content carried by the combined PUCCH is equal to the priority of the UCI with the highest priority in the multiple UCIs forming the combined PUCCH.

For example, as shown in fig. 3, there are five PUCCHs to be transmitted in one slot, where CSI2 PUCCH and SR PUCCH overlap, SR PUCCH and CSI2 PUCCH are merged and transmitted on CSI2 PUCCH, where CSI2+ SR PUCCH (merged) may be referred to as merged PUCCH, because SR PUCCH has higher priority than CSI PUCCH, and thus CSI2+ SR PUCCH (merged) has priority equal to SR PUCCH.

The priority sequence of the five PUCCHs according to the bearing content is as follows: HARQ-ACK/NACK PUCCH > CSI2+ SR PUCCH (combined) > CSI1PUCCH > CSI3 PUCCH.

Since SR PUCCH is merged onto CSI2 PUCCH, CSI2+ SR PUCCH (merged) is a short format, so HARQ-ACK/NACK PUCCH and CSI2 PUCCH will be transmitted, CSI1PUCCH and CSI3 PUCCH and their corresponding UCI will be discarded.

It should be noted that, in the third embodiment, the priority of the HARQ-ACK/NACK PUCCH is higher than the priority of the SR PUCCH, and the priority of the SR PUCCH is higher than the priority of the CSI PUCCH, in fact, for the priorities of at least three non-overlapping PUCCH bearer contents in one slot, the priorities may also be determined specifically according to other information corresponding to the PUCCH bearer contents, for example, according to the size of the cell index corresponding to the PUCCH bearer contents, the smaller the cell index is, the higher the priority of the PUCCH bearer contents is; conversely, the larger the cell index is, the lower the priority of the PUCCH carrying content is.

Example four: the specific parameters include types of at least three non-overlapping PUCCHs within one slot.

If there are at least three non-overlapping PUCCHs within one slot, a PUCCH for transmission is determined based on types of the at least three non-overlapping PUCCHs.

The types of PUCCH mentioned in this embodiment may be divided into a dynamically scheduled PUCCH and a configured PUCCH.

For example, if there are at least three non-overlapping PUCCHs in a slot and a dynamically scheduled PUCCH and a configured PUCCH are included, optionally, the dynamically scheduled PUCCH is transmitted preferentially and at least one of the two PUCCHs is transmitted as a short format PUCCH; or the configured PUCCH is transmitted preferentially, and at least one of the two PUCCHs is transmitted as a short-format PUCCH.

Example five: the specific parameters include a starting symbol and a priority of a bearer content of at least three non-overlapping PUCCHs within one slot.

If there are at least three non-overlapping PUCCHs within one slot, one PUCCH with the earliest starting symbol is transmitted, while one PUCCH with the highest priority of the bearer is transmitted, based on the positions of the starting symbols of the at least three non-overlapping PUCCHs and the priority of the bearer, and at least one of the two transmitted PUCCHs is in a short format.

In order to avoid that the PUCCH with the earliest starting symbol is simultaneously the PUCCH with the highest priority, and simultaneously avoid that both the PUCCH with the earliest starting symbol and the PUCCH with the highest priority are long formats, the embodiment may give priority to the starting symbol and then to the priority of the bearer content; it is of course also possible to prioritize the priority of the bearer content and then to consider the start symbol.

For example, the starting symbol is considered preferentially, then the priority of the carrying content is considered, if the PUCCH with the earliest starting symbol is the PUCCH with the highest priority at the same time, the PUCCH with the earliest starting symbol and the highest priority is determined, and the first PUCCH after the PUCCH is determined according to the sequence of the starting symbol and serves as the PUCCH for transmission, wherein the PUCCH with the earliest starting symbol and the highest priority is in a short format; or determining the PUCCH with the earliest starting symbol and the highest priority, and determining the first short format PUCCH after the position according to the sequence of the starting symbol as the PUCCH for transmission, wherein the PUCCH with the earliest starting symbol and the highest priority is in a long format.

For another example, the starting symbol is prioritized, then the priority of the content is considered, and if the PUCCH with the earliest starting symbol is different from the PUCCH with the highest priority, but both the PUCCH with the earliest starting symbol and the PUCCH with the highest priority are long format, the first short format PUCCH after the PUCCH symbol position with the earliest starting symbol and the PUCCH with the highest priority are used as the PUCCH to be transmitted.

Example six: the specific parameter includes types of at least three non-overlapping PUCCHs within one slot, including a HARQ-ACK/NACK PUCCH for transmission of dynamic scheduling.

If at least three non-overlapping PUCCHs exist in one time slot and the types of the at least three non-overlapping PUCCHs comprise HARQ-ACK/NACK PUCCH used for transmitting dynamic scheduling, the PUCCH for transmission is determined based on the total bit number of the bearing contents of the at least three non-overlapping PUCCHs and PUCCH Resource Indicator (PRI) corresponding to the HARQ-ACK/NACK in the at least three non-overlapping PUCCHs, and UCI of the bearing contents of the at least three non-overlapping PUCCHs is carried.

Specifically, if one PUCCH of the at least three non-overlapping PUCCHs is used for transmitting HARQ-ACK/NACK for dynamic scheduling, UCI contents corresponding to the at least three non-overlapping PUCCHs are combined on the one PUCCH for transmission. Specifically, a resource SET (PUCCHresource SET, RESET) to be used may be determined according to a load size (payload size) of the merged UCI; and then determining the PUCCH used for transmission in the determined RESET according to the PRI corresponding to the HARQ-ACK/NACK in the at least three non-overlapping PUCCHs, and carrying the UCI of the carrying content of the at least three non-overlapping PUCCHs.

For example, as shown in fig. 2, there are four PUCCHs to be transmitted in one slot, which are long-format HARQ-ACK/NACK PUCCHs respectively; a long-format SR PUCCH; a short-format CSI1PUCCH and a short-format CSI2 PUCCH. The terminal equipment multiplexes all UCIs on a PUCCH for transmission, and the determination mode of the PUCCH is that RESET is determined according to the total bit number of HARQ-ACK/NACK + SR + CSI1+ CSI 2; determining PUCCH resources used for transmission in RESET according to PRI corresponding to HARQ-ACK/NACK, carrying the HARQ-ACK/NACK + SR + CSI1+ CSI2, and discarding part of UCI contents according to the existing rule if the maximum code rate of the determined PUCCH resources is exceeded.

Example seven: the specific parameter includes types of at least three non-overlapping PUCCHs within one slot, and HARQ-ACK/NACK PUCCHs for transmission of dynamic scheduling are not included in the types of the at least three non-overlapping PUCCHs.

If there are at least three non-overlapping PUCCHs in a slot and the types of the at least three non-overlapping PUCCHs do not include a HARQ-ACK/NACK PUCCH for transmitting dynamic scheduling, the PUCCH to be transmitted may be determined by referring to the methods provided in the foregoing embodiment one, embodiment two, embodiment three, and embodiment five, and details are not repeated here to avoid repetition.

In the embodiments provided in this specification, if there are at least three non-overlapping PUCCHs in one slot, the terminal device can determine the PUCCH for transmission based on specific parameters of the at least three non-overlapping PUCCHs, which solves the problem that the terminal device cannot determine the PUCCH for transmission, avoids the transmission problem caused by inconsistent understanding of PUCCH transmission between the terminal device and the network device, and improves the effectiveness of communication.
