Embodiment Construction

[0033] Those skilled in the art understand that, as mentioned in the background art, NTN communication directly adopts the DRX solution in the prior art, and it is difficult to take advantage of the power saving advantage of DRX.

[0034] The inventors of the present application have found through research that in 5G NR communication, the network can configure a Discontinuous Reception (DRX) mode for a User Equipment (UE) in a connected state. A UE in the DRX mode does not need to continuously receive a physical downlink control channel (Physical Downlink Control Channel, PDCCH for short).

[0035] Specifically, when the UE in the connected state is in the DRX mode, its parameters and characteristics are as follows:

[0036](1) Discontinuous reception duration timer (drx-onDurationTimer): From the start slot of the DRX cycle (DRX cycle), the UE is fixed in the active state (active) time. During the running of the timer drx-onDurationTimer, the UE is in the active state and ca...

Abstract

A method and device for controlling and indicating UE discontinuous reception, a storage medium, a terminal, and a base station. The control method includes: determining that a MAC entity expects to obtain an uplink grant in response to the scheduling request after sending the scheduling request The shortest duration: allocate an SR response round-trip time timer for the scheduling request, the timing time of the SR response round-trip time timer is equal to the shortest duration, and try to leave the active state during the operation of the SR response round-trip time timer. Through the technical solution provided by the invention, the power consumption of the terminal can be saved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a UE discontinuous reception control and indication method and device, a storage medium, a terminal, and a base station. Background technique [0002] The 3rd Generation Partnership Project (3GPP) is researching the fifth-generation mobile communications (The Fifth-Generation mobile communications, 5G) New Radio (NR) non-terrestrial communication network (Non Terrisal) Network, referred to as NTN). The research scope of 5G NTN communication mainly includes Spaceborne vehicle (Geostationary Earth Oribit Satellites, GEO for short) / Medium Earth Oribiting Satellites (MEO for short) / Low Earth Oribit Statellites (Low Earth Oribit Statellites for short) LEO) and airborne vehicle (airbornevehicle) high altitude platform (High Altitude Platforms, referred to as HAPS). The main characteristic of NTN communication is that its round trip time (Round Trip Time, RT...
