Embodiment Construction

[0038] As mentioned in the background art, the narrowband system has the characteristics of less time-frequency resources, etc., and the wake-up signaling needs to consider the characteristics of the narrowband system. How to optimize the design of wake-up signaling in a narrowband system is an urgent problem to be solved.

[0039] The technical solution of the present invention monitors the wake-up PDCCH, and controls whether the user equipment enters the wake-up state when the monitored PDCCH is a wake-up PDCCH, or when the sleep indication information is obtained from the downlink control information transmitted by the sleep PDCCH, Furthermore, on the one hand, the power consumption of the user can be reduced in scenarios where no data is scheduled, and on the other hand, the PDCCH can be used to instruct the user equipment to enter the wake-up state, which can save time-frequency resources.

Abstract

The invention discloses an awakening method and device, a storage medium and a terminal. The awakening method comprises the following steps: monitoring an awakening PDCCH; if the awakening PDCCH is detected, or, if it is detected that the awakening PDCCH exists and awakening indication information in downlink control information transmitted by the awakening PDCCH indicates that the PDCCH enters anawakening state, determining that the PDCCH enters the awakening state, wherein the awakening state refers to starting of a working duration timer and / or starting of a DRX deactivation timer. According to the technical scheme of the invention, the awakening signaling can be optimally designed in a narrowband system.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a wake-up method and device, a storage medium, and a terminal. Background technique [0002] Generally speaking, in the connected state, the user equipment (User Equipment, UE) is configured at the active time (Active Time ) to monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH). In this way, the user equipment can be periodically put to sleep, so as to achieve the purpose of power saving of the user equipment. Generally speaking, the activation time includes at least the running time of timers such as onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer, drx-RetransmissionTimerShortTTI, drx-ULRetransmissionTimer, drx-ULRetransmissionTimerShortTTI or mac-ContentionResolutionTimer. [0003] In some scenarios, such as scenarios with low packet arrival rate or network congestion, for a given UE, no data is scheduled ...
