Problems solved by technology

[0004] For the activated BWP, the current implementation either needs to wait for the base station to notify the UE to activate the BWP, which brings additional signaling overhead, or wait for the UE's timer to expire before deactivating the BWP, which cannot be deactivated in time. lead to increased power consumption of the UE

Embodiment Construction

[0036] In the NR system, the current BWP deactivation scheme either requires the base station to instruct the user equipment to activate / deactivate BWP through dedicated RRC signaling or DCI, or needs to start a timer for DL ​​BWPs other than the default DL BWP, when the timer expires Then deactivate the BWP. For the activated BWP, the current implementation either needs to wait for the base station to notify the user equipment to activate the BWP, which brings additional signaling overhead, or wait for the timer of the user equipment to expire before deactivating the BWP, which cannot be activated in time BWP, resulting in increased power consumption of the user equipment.

[0037] In the embodiment of the present invention, after the logical channel is released, it is first judged whether there is a BWP that does not correspond to any logical channel, and then when there is an activated BWP that does not correspond to any logical channel, it actively deactivates or directly ...

Abstract

The invention discloses user equipment, a BWP deactivation method thereof and a computer readable storage medium. The method for deactivating the BWP by the user equipment comprises the following steps: after a logic channel is released, judging whether the BWP in an activated state does not correspond to any logic channel or not; when there is an active state BWP that does not correspond to any logical channel, deactivating or directly releasing the BWP. By applying the method, the BWP without any data transmission can be timely deactivated on the premise of not increasing extra signaling overhead.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a user equipment, a method for deactivating a BWP, and a computer-readable storage medium. Background technique [0002] With the continuous development of wireless communication technology, following 3G and 4G, 3GPP introduced 5G New Radio (New Radio, NR) technology. In the NR system, the maximum channel bandwidth of each carrier is 400MHz. Since some user equipment (User Equipment, UE) may not be able to support a bandwidth of 400 MHz, and considering power consumption requirements, a concept of a partial bandwidth (Bandwidth Part, BWP) is introduced. For each carrier, the base station can configure one or more BWPs for the UE. The UE can use different BWPs for communication by activating / deactivating the BWP. BWP is divided into uplink (Uplink, UL) BWP and downlink (Downlink, DL) BWP. [0003] There are currently two implementation schemes for activ...
