Abstract

Embodiments of the present invention provide a signal transmission method and device, which are applied to the technical field of communications, so as to solve the problem of UE power consumption inthe existing wake-up signal transmission process. The method comprises the following steps: sending first information, and sending M wake-up signals, wherein the first information is used for indicating the number N, the number N is the number of terminal device groups obtained by grouping X terminal devices, paging opportunities of the X terminal devices are the same, the M wake-up signals are used for indicating whether the terminal devices of the N terminal device groups monitor paging signals at the paging opportunity, one wake-up signal is used for indicating whether the terminal devicesof all or part of the N terminal device groups monitor the paging signal at the paging opportunity, the group number of all or part of the terminal device groups is smaller than or equal to a first threshold, the first threshold is a positive integer, X and N are integers greater than 1, and M is a positive integer.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal transmission method and device. Background technique [0002] At present, in each Discontinuous Reception (DRX) cycle of the RRC (Radio Resource Control, Radio Resource Control) idle (idle) state, the user equipment (user equipment, UE) blindly detects the paging occasion (Paging Occasion , PO) before the paging (Paging) signal, the base station will transmit a wake-up signal to the UE, and the UE wakes up at a corresponding time to detect the wake-up signal. Wherein, if the wake-up signal instructs the UE to blindly detect the Paging Physical Downlink Control Channel (Paging Physical Downlink Control Channel, Paging PDCCH), the UE continues to blindly detect the subsequent corresponding Paging PDCCH; otherwise, the UE does not blindly detect the Paging PDCCH. [0003] However, in related technologies, a PO supports the transmission o...
