Problems solved by technology

If the UE does not distinguish the priority of the channel, the UE will multiplex different channels according to the established multiplexing rules; if it distinguishes the priority, then in the overlapping scenario, the low priority channel will always be discarded, which greatly affects the Transmission performance of low priority channels

Embodiment 1

[0083] Such as image 3 As shown in the figure, P represents priority indication, P=0 represents low priority, P=1 represents high priority; M represents transmission indication multiplexing indicator, M=0 represents no multiplexing support, and M=1 represents multiplexing support. According to the priority indication, the HARQ-ACK PUCCH (that is, the PUCCH carrying HARQ-ACK) is a high-priority channel, and CG PUSCH1 and CGPUSCH2 are different configuration authorization PUSCHs, and their priorities are low priority and high priority respectively. At the same time, all three channels are configured or indicated with corresponding M / P identifiers, where M=1 (or 'Multiplexing') means that multiplexing with other channels is allowed, and M=0 (or 'Prioritization') means Does not support multiplexing with other channels, but supports priority transmission (priortizaition), by image 3 It can be seen that all three channels support multiplexing. The resources of the HARQ-ACK PUCCH...

Embodiment approach 1

[0084]Embodiment 1: UE processes the multiplexing between channels with the same priority first, that is, first processes the multiplexing between HARQ-ACK PUCCH and CG PUSCH2 with the same priority, and the UE multiplexes HARQ-ACK on CG PUSCH2 for transmission. Since the time domain resources of CG PUSCH1 and CG PUSCH 2 do not overlap, the UE transmits CG PUSCH 1 and CG PUSCH2 respectively.

Embodiment approach 2

[0085] Embodiment 2: The UE assumes that all transmissions have the same priority or no priority. image 3 The figure shows HARQ-ACK PUCCH and multiple PUSCHs. According to related technologies, when PUCCH and multiple PUSCH time domain resources overlap, UE selects the way of multiplexing PUSCH. Assuming that the subcarrier space (subcarrier space, SCS) of different serving cells CC0, CC1 and CC2 is the same, then PUSCH 1 and PUSCH 2 are in the same slot, and the UE selects the corresponding CG with a smaller serving cell index for multiplexing on PUSCH 1 according to the serving cell index HARQ-ACK transmission. Since the time domain resources of CG PUSCH 1 and CG PUSCH 2 do not overlap, the UE transmits CG PUSCH 1 and CG PUSCH 2 respectively.

Abstract

The embodiment of the invention discloses an uplink transmission processing method, a device and a terminal, and belongs to the technical field of communication. The uplink transmission processing method is applied to the terminal, and comprises the following steps: acquiring a transmission identifier of each uplink transmission, the transmission identifier being used for indicating whether the uplink transmission supports multiplexing with other uplink transmissions when the uplink transmission overlaps with other uplink transmissions on a time domain resource; and performing uplink transmission according to the transmission identifier. According to the technical scheme of the invention, the transmission performance of the channel can be ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an uplink transmission processing method and device, and a terminal. Background technique [0002] In related technologies, a terminal (User Equipment, UE) does not distinguish channel priorities; or distinguishes channel priorities, but does not support multiplexing between channels with different priorities. If the UE does not distinguish the priority of the channel, the UE will multiplex different channels according to the established multiplexing rules; if it distinguishes the priority, then in the overlapping scenario, the low priority channel will always be discarded, which greatly affects the Transmission performance for low priority channels. Contents of the invention [0003] Embodiments of the present invention provide an uplink transmission processing method, device, and terminal, capable of ensuring channel transmission performance. [0004] I...
