Embodiment Construction

[0061] Those skilled in the art understand that, as mentioned in the background, the existing multiplexing resource indication scheme is still implemented based on the system grid, and such a scheme will result in the need for the number of transmission bits required for mapping the obtained system grid bitmap Changes with the granularity of the system grid.

[0062] For example, if it is desired to reduce the transmission overhead of the system grid bitmap, the system grid can only select a coarser resource division granularity, which in turn results in resources used by the physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) channel Among them, the number of resources that can be multiplexed by the Physical Downlink ShareChannel (PDSCH) channel decreases sharply, seriously affecting the multiplexing resource utilization rate of the user equipment; and if you want to improve the multiplexing resource utilization rate of the user equipment, yo...

Abstract

A resource multiplexing method and device, a storage medium, a terminal and a base station are provided. The method includes the following steps: determining a first reserved resource reserved for a PDCCH (Physical Downlink Control Channel) in the resources used in the overlapping area of the PDCCH and a PDSCH (Physical Downlink Shared Channel); mapping the first reserved resource from a system grid to a signaling grid to obtain a signaling grid bitmap; and sending the signaling grid bitmap to user equipment, wherein the system grid contains M resource blocks, the signaling grid is constructedon the resources used in the overlapping area of the PDCCH and the PDSCH and contains K resource grids, K and M are positive integers, and K is smaller than M. Through the scheme provided by the invention, the resources which can be multiplexed by the PDSCH in the resources used by the PDCCH can be indicated with less overhead, and the overhead is constant. Moreover, the user equipment can use the resources multiplexed by the PDCCH to the PDSCH more efficiently.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource multiplexing method and device, a storage medium, a terminal, and a base station. Background technique [0002] In the 5G new radio (New Radio, NR for short) system, the control channel (Control Channel) is a set of signals located in the first to three Orthogonal Frequency Division Multiplexing (OFDM) symbols in the transmission slot. Control Resource Set (Control Resource Set, referred to as CORESET). Wherein, each control resource set includes a group of control channel elements (Control Channel Element, referred to as CCE, and may also be called a control channel element), and the CCE includes downlink control information (Downlink Control Information, referred to as DCI) and uplink control information; Each CCE is composed of one or more resource element groups (Resource Element Group, REG for short). [0003] In practical applications, the ...
