摘要

Embodiments of the present application provide a control channel transmission method and device and a storage medium. The method applied to a network device side includes: the network device maps a first control channel to S first transmission units included in a first control resource set, the first control resource set is a control resource set on a first BWP, the first BWP includes N subbands, the first control resource set is located on at least one subband of the N subbands, the first transmission unit is a smallest unit for transmitting a control channel, S and N are positive integers, S≥1 and N≥2; further, the network device transmits the first control channel to a terminal device.

說明書

In the foregoing embodiment, each of the multiple subbands included in the BWP is configured with a control resource, and each subband is used to transmit the PDCCH. However, in some cases, a same PDCCH may be transmitted on each subband, causing greater redundancy in the transmission of the PDCCH, resulting in a waste of resources. To solve this problem, an embodiment provides an improved solution. The base station configures a control resource on each of the multiple subbands included in the BWP, but during actual transmission of the PDCCH, the PDCCH is only transmitted in the control resource of one subband, and the control resources of other subbands are used for data transmission, thereby improving the resource utilization rate on the unlicensed spectrum. The solution will be introduced below in conjunction with specific embodiments.
