Problems solved by technology

[0003] In the current NR discussion, it is proposed that when multiple uplink transmission channels of the same UE overlap in time domain, the low priority uplink transmission will be canceled in whole or in part, and the high priority uplink transmission will be transmitted normally, but considering the low priority The uplink transmission is canceled, causing the low priority uplink transmission to be retransmitted. If the uplink transmission is control signaling, for example, HARQ-ACK PUCCH, then the downlink data corresponding to HARQ-ACK needs to be retransmitted
Obviously, directly canceling low-priority uplink transmission will reduce the efficiency of low-priority uplink transmission

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0032] figure 1 is an example diagram of channel conflict in the embodiment of this application, see figure 1 , taking the time-domain overlap of transmission resources of one HARQ-ACK PUCCH and another PUSCH (with uplink data) as an example, where the high-priority uplink channel is HARQ-ACKPUCCH, the low-priority uplink channel is PUSCH, and the HARQ-ACK PUCCH There is a time domain overlap with the PUSCH transmission resources, causing the HARQ-ACK PUCCH to conflict with the PUSCH. In some cases, the low-priority uplink channel has already started to transmit, and the high-priority upli...

Abstract

The invention provides a channel conflict processing method and device, equipment and a storage medium. The channel conflict processing method comprises the steps of: determining a transmission cancelstarting position of a low-priority uplink channel when transmission resource time domains of a high-priority uplink channel and a low-priority uplink channel of the same UE are overlapped; and cancelling transmission resources of the low-priority uplink channel according to the cancelling start position. According to the channel conflict processing method and the device provided by the embodiment of the invention, when the channels conflict, the influence of the high-priority uplink channel on the low-priority uplink channel is reduced by determining the transmission cancel starting positionof the low-priority uplink channel, and the transmission efficiency of the low-priority uplink channel is improved.

Description

technical field [0001] The present application relates to a wireless communication network, and in particular to a channel conflict processing method, device, device and storage medium. Background technique [0002] In the existing 5G technology NR, the same UE can support different types of services, such as supporting eMBB service transmission and uplink channel transmission related to eMBB service, and can also support URLLC service transmission and uplink channel transmission related to URLLC service at the same time . However, considering the complexity of UE implementation, a UE is allowed to transmit only one uplink channel within a certain period of time. For example, when there are two uplink channels overlapping in the time domain of the UE, the UE can only choose to transmit one of them. The other should be canceled in whole or in part. [0003] In the current NR discussion, it is proposed that when multiple uplink transmission channels of the same UE overlap in...
