Embodiment Construction

[0114] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0115] The present invention aims at the problem of scheduling restrictions on the base station side caused by overlapping resource positions of PDSCH and PDCCH in the prior art, and provides a channel transmission method, which is applied to terminals, such as figure 1 shown, including:

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

[0117] In the channel transmission method provided by the embodiment of the present invention, when the resource position u...

Abstract

The present invention provides a channel transmission method, device, terminal and base station, wherein the channel transmission method includes: when the resource position used for the physical downlink shared channel PDSCH transmission of the terminal is different from the other non-scheduled PDSCH of the terminal When the resource positions occupied by the physical downlink control channel PDCCH overlap, the same processing method as the base station is used to map the PDSCH data. In this solution, when the resource position used for the transmission of the physical downlink shared channel PDSCH of the terminal overlaps with the resource position occupied by other physical downlink control channels PDCCH of the terminal that does not schedule the PDSCH, the same method as the base station is adopted. The processing method maps PDSCH data; it can make the base station and the terminal have the same understanding when the PDSCH and PDCCH resource positions overlap, and reduce the scheduling restrictions on the base station side.

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 ...
