Problems solved by technology

[0005] However, if multiple overlapping uplink channels include an uplink channel for carrying URLLC UCI and an uplink channel for carrying enhanced mobile ultra-broadband (Enhance Mobile Broadband, eMBB) UCI, at this time, if the terminal device is based on the existing multiplexing The transmission method multiplexes and transmits multiple overlapping uplink channels, which will increase the delay of URLLC UCI and reduce user experience.
[0006] Moreover, when multiple overlapping uplink channels multiplex one uplink channel for transmission, part of the data carried on the multiple overlapping uplink channels may be lost, reducing the transmission performance and the success rate of data transmission
[0007] In addition, when there are too many overlapping channels, the complexity of the multiplexing transmission mechanism will be increased

Abstract

Provided are a wireless communication method and device. The wireless communication method comprises the steps: if at least two types of uplink channels to be transmitted overlap, determining a target uplink channel based on the overlapping condition of the at least two uplink channels to be transmitted, wherein the at least two to-be-transmitted uplink channels are respectively used for transmitting part or all information borne by the at least two types of uplink channels; and sending the target uplink channel, wherein the target uplink channel is used for transmitting part or all of information borne by the at least two uplink channels to be transmitted. Based on the above technical scheme, not only can the actual transmission demand be ensured based on the priorities of different types of uplink channels to improve the user experience, but also the probability of multiplexing information carried by a plurality of uplink channels to one uplink channel for transmission can be reduced to improve the transmission performance and the success rate of data transmission. In addition, the judgment condition of multiplexing transmission can be preferentially simplified, and the complexity of a multiplexing transmission mechanism is reduced.

Description

[0001] This application is a divisional application of the application dated July 26, 2019, the application number is 201980048625.6, and the invention name is "wireless communication method and equipment". technical field [0002] The embodiments of the present application relate to the communication field, and more specifically, to a wireless communication method and device. Background technique [0003] New Radio (NR) Rel-15 stipulates that when multiple uplink channel resources collide and meet the multiplexing transmission conditions, the terminal device can control the uplink according to the type of uplink control information (Uplink control information, UCI) The channel format of the physical uplink control channel (PUCCH) determines the multiplexing transmission mode. Wherein, the multiplexing transmission mode refers to transmitting information carried by multiple uplink channels through one multiplexed uplink channel. [0004] In addition, NR Rel-16 enhances Ultr...
