Embodiment Construction

[0038] As mentioned in the background art, the existing UE cannot well filter out the falsely detected DCI indicating BWP switching, which seriously affects the communication quality with the base station.

[0039] Specifically, NR currently only performs a simple bit field judgment on the DCI indicating BWP switching. Sometimes the falsely picked DCI cannot be completely filtered out only by the bit field judgment, and each bit field judgment is difficult for some UEs. It is said that the processing time is too long, which affects the subsequent process scheduling. Therefore, the UE using the prior art may easily trigger the BWP handover process by mistake, resulting in out-of-synchronization between the UE and the base station, and affecting communication performance.

[0040] In order to solve the above technical problems, the inventors of the present application analyzed the description of the communication protocol 38.213 and found that, from the UE detecting the DCI indi...

Abstract

A processing method and device for BWP switching indication, and a computer readable storage medium are disclosed, the method comprising: in response to detection of DCI indicating BWP switching, determining whether effective uplink and downlink scheduling occurs to an original BWP before switching to a target BWP; and if a result shows that the effective uplink and downlink scheduling does not occur, switching to the target BWP. Through the scheme of the invention, the false detection DCI for indicating the switching of the BWP can be filtered out more accurately, the UE and the base station are always in the same BWP, and the communication quality is improved and ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a processing method and device for a BWP switching instruction, and a computer-readable storage medium. Background technique [0002] Since the new radio (New Radio, referred to as NR, also known as the new air interface) has a higher frequency band and is more sensitive to the channel environment, some frequency bands of NR share time-frequency domain resources with Long Term Evolution (LTE). And there are many same-frequency cells in the outfield. The false detection rate of downlink control information (DCI) of a user equipment (User Equipment, UE for short) running in an actual wireless environment is generally high. For example, a DCI indicating a Bandwidth Part (BWP for short) is falsely detected. [0003] Since the BWP handover may cause the UE to lose contact with the base station, if the UE falsely picks up the DCI indicating the BWP handover, the ...
