Example Embodiment

[0114] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0115] Aiming at the problem of scheduling restrictions on the base station side when the resource positions of PDSCH and PDCCH overlap in the prior art, the present invention provides a channel transmission method, which is applied to a terminal, such as figure 1 Shown, including:

[0116] Step 11: When the resource location used for the physical downlink shared channel PDSCH transmission of the terminal overlaps with the resource location occupied by the other physical downlink control channel PDCCH of the terminal that does not schedule the PDSCH, the same as the base station The processing method maps PDSCH data.

[0117] The channel transmission method provided by the embodiment of the present invention uses the position of the resource...

Abstract

The invention provides a channel transmission method and device, a terminal and a base station. The channel transmission method comprises the following steps: when the resource position used by the PDSCH transmission of the terminal is overlapped with the resource positions occupied by other physical downlink control channels (PDCCH) of the terminal which do not schedule the PDSCH, mapping the PDSCH data by adopting the same processing mode as the base station. According to the scheme, when a resource position used by a physical downlink shared channel (PDSCH) of the terminal is overlapped with resource positions occupied by other physical downlink control channels (PDCCHs) of the terminal, PDSCH data is mapped by adopting the same processing mode as a base station, so that the base station and the terminal have the same understanding when the PDSCH resource position and the PDCCH resource position are overlapped, and the scheduling limitation of the base station side is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a channel transmission method, device, terminal and base station. Background technique [0002] Currently, in the Long Term Evolution LTE system, the resource area for transmitting downlink control channels is completely isolated from the resource area for transmitting data channels, so there is no overlap between the physical downlink shared channel PDSCH and the physical downlink control channel PDCCH. [0003] In the new air interface NR system, in order to improve spectrum efficiency, there is no actual PDCCH transmission resource in the control resource set CORESET that can be used for downlink data channel transmission. However, when the PDSCH conflicts with other downlink control channel PDCCH candidate (candidate) resources of the terminal, there is currently no clear solution. [0004] According to the processing method in the current NR system, when the ...
