Embodiment Construction

[0045] As mentioned in the background, in the application scenario of the narrowband system, time-frequency resources are less, and if the UE is instructed to go to sleep through a MAC layer command, PDCCH and Physical Downlink Shared Channel (PDCCH) resources need to be consumed. Therefore, how to optimize the design of the sleep-entry signaling in the narrowband system is an urgent problem to be solved.

[0046] The technical solution of the present invention determines whether to enter the sleep state by monitoring the PDCCH. On the one hand, the power consumption of the user can be reduced in scenarios such as low packet arrival rate or network congestion, and on the other hand, it can avoid instructing the user equipment to enter sleep through MAC layer commands. Save time and frequency resources.

[0047] The Fangming technical solution can be applied to 5G (5Generation) communication systems, 4G, 3G communication systems, and various new communication systems in the fut...

Abstract

The invention discloses a method and apparatus for entering a sleep state, a storage medium, and user equipment. The method comprises the steps: monitoring a PDCCH, and determining whether a sleep state needs to be entered, wherein the sleep state is to ignore a part of PDCCH monitoring opportunities or to modify PDCCH configuration. According to the technical scheme of the invention, the sleep signaling can be optimally designed in a narrowband system.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for entering sleep, a storage medium, and user equipment. 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 low packet arrival rate scenarios or network congestion scenarios, no data is sche...
