Embodiment Construction

[0050] Those skilled in the art understand that, as mentioned in the background, in order to ensure that the user equipment (User Equipment, referred to as UE) can multiplex the available resources in the control channel in the time domain and the frequency domain, the network needs to identify the resources that can be reused The location of the multiplexed resource bitmap is indicated to the user equipment. Wherein, the available resources in the control channel may include available resources carried by a physical downlink control channel (Physical Downlink Control CHannel, PDCCH for short), that is, resources reserved in the PDCCH channel but not used for control (also called are unused resources); based on the latest protocol, it is allowed to share resources between the PDCCH channel and the PDSCH channel, that is, the user equipment multiplexes the available resources on the PDCCH channel to the Physical Downlink Shared Channel (Physical Downlink Shared Channel (Physical...

Abstract

A resource multiplexing method and device, a storage medium, a terminal and a base station are provided. The method includes the following steps: judging whether there is overlap of resource allocation in time domain based on first DCI (Downlink Control Information), wherein the first DCI is obtained from a control area of a downlink slot; if the judgment result shows that there is overlap of resource allocation in time domain, obtaining a multiplexed resource bitmap based on information allocated in a non-controlled area of the downlink slot; and determining a control resource multiplexed bya PDCCH (Physical Downlink Control Channel) to a PDSCH (Physical Downlink Shared Channel) based on the first DCI and the multiplexed resource bitmap. Through the scheme provided by the invention, thelocation of a multiplexed resource can be indicated with less blind test, small control delay and low energy consumption, so that user equipment can efficiently multiplex the resources used by the control channel.

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, 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; A CCE is composed of one or more resource element groups (Resource Element Group, REG for short). [0003] In practical applications, the configured control...
