Method and device for configuring BWP related measurement gap, base station and user equipment

Abstract

The invention provides a method and device for configuring a BWP related measurement gap, a base station and user equipment. At a base station side, the method comprises the following steps: for eachBWP configured by UE in a connected state, judging whether a measurement gap is needed or not during measurement by the UE when activating the BWP according to the BWP and a neighbor cell to be measured by the UE; when it is judged that a measurement gap is needed or not during measurement by the UE when the BWP is activated, obtaining corresponding measurement gap parameters; and sending whethereach BWP has a corresponding measurement gap and a corresponding measurement gap parameter to the UE. At a user equipment side, the method comprises the following steps: receiving whether each BWP configured by a base station has a corresponding measurement gap and a corresponding measurement gap parameter or not; and according to the currently activated BWP, selecting whether to use the measurement gap for measurement. According to the invention, the BWP related measurement gap can be flexibly configured, and the performance of the UE is ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device, base station and user equipment for configuring BWP-related measurement gaps. Background technique [0002] With the development of wireless communication technology, 3GPP has introduced NR (New Radio, new air interface) technology. In 3GPP (3rdGeneration Partnership Project, third generation partnership project) R15 (the first generation of 5G standard), because some UEs (User Equipment, user equipment) may not be able to support the maximum bandwidth of the carrier, and considering UE power consumption, The concept of BWP (Bandwidth Part, bandwidth part) is introduced in NR. For each serving cell, the base station can configure one or more BWPs for the UE. For UE, at a given moment, each serving cell activates at most one downlink BWP and one uplink BWP. [0003] The base station can activate the BWP of the UE through dedicated RRC (R...

Problems solved by technology

However, this method may affect the performance of the UE. For example, if the UE is configured with 2 BWPs, one of which needs a measurement gap, the base station always configures a measurement gap for the UE, then even if the currently activated BWP of the UE does not require a measurement gap, the base station will still be in the measurement gap UE is not scheduled during this period

In addition, even if there are multiple BWPs that require measurement gaps, when the UE activates different BWPs, the subcarrier spacing and time slot length may be different, and the service characteristics of the UE may be different. Only the same measurement gap can be configured according to the above method. will lack flexibility
