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, the method comprising: determining the first reserved resource reserved for the PDCCH channel among the resources used in the overlapping area of ​​the PDCCH channel and the PDSCH channel; Resources are mapped from the system grid to the notification grid to obtain the notification grid bitmap; the notification grid bitmap is sent to the user equipment; wherein, the system grid includes M resource blocks, and the notification grid is constructed on the PDCCH channel and PDSCH The resource used in the overlapping area of ​​the channel contains K resource grids, K and M are positive integers, and K

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 ...
