Problems solved by technology

In this way, regardless of whether the terminal performs reference signal measurement after receiving the WUS, it needs to enter the on-duration timer after an interval of offset, resulting in a long delay in signal transmission.

Abstract

The invention provides a signal receiving method and device. The method comprises the following steps: a terminal receives a first signal at a first moment, and determines the length of a first offsettime period according to the first signal, so that the terminal can determine the starting moment of a duration timer according to the first offset time period and the first moment, and receive a second signal within the time period of the duration timer. That is to say, according to the embodiment of the invention, the offset value between the first moment when the terminal receives the first signal and the starting moment of the duration timer is flexibly changed; compared with a traditional scheme in which the offset value is fixed, the method in the embodiment of the invention reduces thesignal transmission delay, and correspondingly, reduces the signal detection and receiving duration of the terminal, i.e., reduces the power consumption of the terminal.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a signal receiving method and device. Background technique [0002] In a traditional solution, a discontinuous reception (discontinuous reception, DRX) cycle is used to save power consumption of the terminal. Specifically, the network device configures a DRX cycle for the terminal in the connected state. In the DRX cycle, only a period of time (which may be called an on-duration timer) detects data, and does not detect data at other times. [0003] In order to further reduce the power consumption of the terminal, a wake up signal (wake up signal, WUS) is introduced, and the terminal determines whether to receive a physical downlink control channel (physical downlink control channel, PDCCH) during the on duration timer according to the WUS. In order to improve the reliability of the received data, an offset value (offset) is introduced, that is, the time interval betw...
