Embodiment 1

[0090] Embodiment 1: The network instructs the UE to monitor the PDCCH scheduled by the downlink data through the ACK DCI / NACK or WUS corresponding to the uplink data

[0091] image 3 It is a schematic flow chart of a specific implementation manner of the embodiment of the present invention. The network can issue downlink data scheduling information in the uplink pre-configured resource search space window. Therefore, the UE needs to periodically monitor the data scheduling PDCCH in the uplink pre-configured resource search space window. However, in many cases, the network does not have downlink data to send, and not every uplink pre-configured resource search space window has downlink scheduling information, and the UE's behavior of periodically monitoring the PDCCH will cause power waste.

[0092] refer to image 3 , in order to save energy consumption of the UE, the embodiment of the present invention introduces indication information (not shown) to indicate whether the ...

Embodiment 2

[0096] Embodiment 2: The network indicates whether the UE needs to receive the indication information and the wake-up signal and send the downlink beam (beam) information through the ACK DCI / NACK corresponding to the uplink data.

[0097] Usually, when the network sends downlink scheduling information or downlink data, it needs to determine the sending direction of the downlink beam. Therefore, when the UE does not send uplink data for a period of time, in order to perform downlink reception, the UE needs to report the sending direction of some downlink beams. In many cases, the network may have no downlink data to send for a long time. During this period, if the UE still performs wake-up signal detection and downlink beam information reporting, it will also cause unnecessary energy consumption. For this reason, in this embodiment, the ACK DCI / NACK corresponding to the uplink data is used to carry indication information, and the indication information may indicate whether the ...

Abstract

A signaling sending and receiving method and device, a storage medium, a base station, and a terminal. The signaling sending method includes: sending instruction information, and the instruction information is used to indicate whether the terminal monitors a PDCCH in a PUR search space window. The technical solution provided by the invention can reduce the energy consumption of the UE.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a signaling sending and receiving method and device, a storage medium, a base station, and a terminal. Background technique [0002] In the Fifth-Generation mobile communications (5G for short) New Radio (NR for short) system, in the radio resource control (Radio Resource Control, RRC for short) idle state (idle state), the user equipment When sending uplink data or downlink data (User Equipment, referred to as UE), it needs to switch from a dormant state to a connected state (connected state). [0003] At present, there is a way that a UE can directly send a small amount of uplink data in a dormant state, that is, the network configures a dedicated and periodic uplink preconfigured resource (Preconfigure Uplink resource, PUR for short) and a corresponding downlink search space window for the UE, The UE can send uplink data through PUR, and can monitor a physic...
