It should be noted that, in this embodiment of this application, it is not required that all UCI (such as a first-priority HARQ-ACK, first-priority CSI, a second-priority HARQ-ACK, and second-priority CSI) should be multiplexed on the target PUSCH. When UCI is not multiplexed on the target PUSCH, there is no need to determine the number of coded modulation symbols per layer for multiplexing the UCI on the target PUSCH, and a corresponding value thereof (such as the following Q′_ACK,HPand Q′_ACK,LP) is 0.

In a specific application, because there may be uplink service information on the target PUSCH, that is, the PUSCH with UL-SCH, or there may be no uplink service information on the target PUSCH, that is, the PUSCH without UL-SCH, in different cases, different manners may be used to determine the number of coded modulation symbols per layer in a case that the first target UCI and the second target UCI are multiplexed on the target PUSCH. The following describes the two cases separately.

(I) There is uplink service information, that is, an uplink shared channel (UL-SCH), on the target PUSCH.

In this possible implementation, there is uplink service information on the target PUSCH, and the target PUSCH does not use type B repetition, that is, the target PUSCH does not use repetition type B.

In a specific application, because a priority of the target PUSCH may be the first priority or the second priority, to improve efficiency of a communications system, for target PUSCHs with different priorities, different manners may be used to determine the number of coded modulation symbols per layer when target UCI is multiplexed on the target PUSCH. The following describes the manners separately.

1. The priority of the target PUSCH is the first priority.

In a possible implementation, in a case that there is uplink service information on the target PUSCH and that the priority of the target PUSCH is the first priority, for a second-priority target HARQ-ACK included in the second target UCI, the number Q′_ACK,HPof coded modulation symbols per layer when the target HARQ-ACK is multiplexed on the target PUSCH may be determined according to the following formula:

For an OFDM symbol carrying a DMRS on the PUSCH, its corresponding M_sc^UCI(l) is 0. For an OFDM symbol not carrying a DMRS on the PUSCH, its corresponding M_sc^UCI(l) is M_sc^UCI(l)=M_sc^PUSCH−M_sc^PT-RS(l).

In this embodiment of this application, for PUSCHs with different priorities and UCI with different priorities and/or of different types, β_offset^PUSCHmay be the same or different, and may be specifically determined based on an actual application. This is not specifically limited in this embodiment of this application.

- where α₄is the fourth control factor, O_ACK,LPis the number of bits of the target HARQ-ACK, and L_ACK,LPis the number of CRC bits corresponding to the target HARQ-ACK; Q′_ACK,HPis the number of coded modulation symbols per layer when the second-priority HARQ-ACK is multiplexed on the target PUSCH, and may be determined according to the foregoing formula (25); and if the second-priority CSI multiplexed on the target PUSCH does not include the CSI part2, Q′_CSI-1,HPis determined according to the foregoing formula (33), and a value of Q′_CSI-2,HPis 0; or if the second-priority CSI multiplexed on the target PUSCH includes the CSI part2, Q′_CSI-1,HPis determined according to the foregoing formula (31), and Q′_CSI-2,HPis determined according to the foregoing formula (32).

In the technical solution provided in this embodiment of this application, for multiplexing on PUCCHs and PUSCHs with different priorities, a method for calculating the number of coded modulation symbols per layer in a case that UCI with different priorities is multiplexed on PUSCHs with different priorities is provided, to improve effectiveness of the communications system.

An embodiment of this application further provides a CSI transmission method. The method provides a processing solution when HP CSI on a PUCCH and LP aperiodic CSI (Aperiodic CSI, A-CSI) on a PUSCH overlap in time domain resources.

The method includes one of the following processing manners.

Manner 1: When HP CSI on a PUCCH and LP aperiodic CSI (Aperiodic CSI, A-CSI) on a PUSCH overlap in time domain resources (that is, the PUCCH carrying the HP CSI and the LP PUSCH carrying the A-CSI overlap in time domain resources), transmission of the PUSCH is canceled, and only the PUCCH carrying the HP CSI is transmitted.

Manner 2: When HP CSI on a PUCCH and LP aperiodic CSI (Aperiodic CSI, A-CSI) on a PUSCH overlap in time domain resources (that is, the PUCCH carrying the HP CSI and the LP PUSCH carrying the A-CSI overlap in time domain resources), if the PUSCH includes uplink service information, the HP CSI is multiplexed on the PUSCH for transmission, and the LP A-CSI is discarded; or if the PUSCH does not include uplink service information, transmission of the PUSCH is canceled, and only the PUCCH carrying the HP CSI is transmitted.

Manner 3: When HP CSI on a PUCCH and LP aperiodic CSI (Aperiodic CSI, A-CSI) on a PUSCH overlap in time domain resources (that is, the PUCCH carrying the HP CSI and the LP PUSCH carrying the A-CSI overlap in time domain resources), if a HARQ-ACK is multiplexed on the PUSCH, the HP CSI and the HARQ-ACK are multiplexed on the PUSCH for transmission, and the LP A-CSI is discarded.

That a HARQ-ACK is multiplexed on the PUSCH includes at least one of the following:

- (1) the HP CSI and the HARQ-ACK are multiplexed on one PUCCH; and
- (2) the PUCCH carrying the HARQ-ACK and the PUSCH overlap in time domain resources.

Optionally, a priority of the HARQ-ACK is a second priority.

An embodiment of this application further provides a CSI transmission method. The method provides a processing solution when HP CSI on a PUCCH and semi-persistent CSI (SP-CSI) on an HP PUSCH overlap in time domain resources. The method includes: when the PUCCH carrying the HP CSI and the HP PUSCH carrying the SP-CSI overlap in time domain resources, canceling transmission of the SP-CSI, and transmitting the PUCCH carrying the HP CSI.

It should be noted that the method for determining the number of coded modulation symbols according to this embodiment of this application may be performed by an apparatus for determining the number of coded modulation symbols, or a control module configured to perform the method for determining the number of coded modulation symbols in the apparatus for determining the number of coded modulation symbols. An apparatus for determining the number of coded modulation symbols according to an embodiment of this application is described by assuming that the method for determining the number of coded modulation symbols is performed by the apparatus for determining the number of coded modulation symbols in this embodiment of this application.

FIG. 3 is a schematic diagram of a structure of an apparatus for determining the number of coded modulation symbols according to an embodiment of this application. As shown in FIG. 3, the apparatus 300 mainly includes an obtaining module 301, a first determining module 302, and a second determining module 303.

In this embodiment of this application, the obtaining module 301 is configured to obtain at least one control factor, where the control factor is used to limit a resource occupied when uplink control information UCI is multiplexed on a physical uplink shared channel PUSCH; the first determining module 302 is configured to determine first target UCI and second target UCI multiplexed on a target PUSCH for transmission, where a priority of the first target UCI is a first priority, a priority of the second target UCI is a second priority, and the first priority is lower than the second priority; and the second determining module 303 is configured to separately determine, according to a target control factor, the number of coded modulation symbols per layer in a case that the first target UCI and the second target UCI are multiplexed on the target PUSCH, where the target control factor is one or more of the at least one control factor.

In a possible implementation, in a case that UCI with different priorities is multiplexed on PUSCHs with different priorities, corresponding control factors are different.

In a possible implementation, the at least one control factor includes at least one of the following: a first control factor used to control a resource occupied when first-priority UCI is multiplexed on a first-priority PUSCH; a second control factor used to control a resource occupied when second-priority UCI is multiplexed on a first-priority PUSCH; a third control factor used to control a resource occupied when second-priority UCI is multiplexed on a second-priority PUSCH; and a fourth control factor used to control a resource occupied when first-priority UCI is multiplexed on a second-priority PUSCH.

In a possible implementation, the separately determining, by the second determining module 303 according to a target control factor, the number of coded modulation symbols per layer in a case that the first target UCI and the second target UCI are multiplexed on the target PUSCH includes: separately determining, in the following order, the number of coded modulation symbols per layer in a case that the first target UCI and the second target UCI are multiplexed on the target PUSCH:

- first determining the number of coded modulation symbols per layer in a case that high-priority UCI is multiplexed on the target PUSCH, and then determining the number of coded modulation symbols per layer in a case that low-priority UCI is multiplexed on the target PUSCH, where in a case that UCI with a same priority includes different types of UCI, the number of coded modulation symbols per layer when hybrid automatic repeat request acknowledgement HARQ-ACK information is multiplexed on the target PUSCH is first determined, and then the number of coded modulation symbols per layer when channel state information CSI is multiplexed on the target PUSCH is determined; or
- first determining the number of coded modulation symbols per layer when hybrid automatic repeat request acknowledgement HARQ-ACK information is multiplexed on the target PUSCH, and then determining the number of coded modulation symbols per layer when channel state information CSI is multiplexed on the target PUSCH, where in a case that a same type of UCI includes UCI with different priorities, the number of coded modulation symbols per layer in a case that high-priority UCI is multiplexed on the target PUSCH is first determined, and then the number of coded modulation symbols per layer in a case that low-priority UCI is multiplexed on the target PUSCH is determined.
