Problems solved by technology

[0003] However, in the prior art, when performing BWP switching on a terminal, factors such as the actual demand of terminal services and quality of service (QOS) parameters are not considered, so the allocation of bandwidth resources is not optimal. Affects service quality, thereby making user experience poor

Embodiment Construction

[0024] The method, device, and system for switching bandwidth of a terminal portion provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0025] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0026] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects, or to distinguish different processes for the same object, rather than to describe a specific sequence of objects.

[0027] In addition, the terms "including" and "having" mentioned in the description of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, ...

Abstract

The invention provides a terminal bandwidth part (BWP) switching method, device and system, and relates to the technical field of wireless communication, and the terminal BWP switching method is better in bandwidth resource distribution and higher in service quality compared with an existing terminal BWP switching method. The method comprises the following steps: acquiring a target BW required bya target service carried out by a terminal at the current moment, a current BWP used by the terminal at the current moment, a to-be-switched BWP and a service type of the target service; when the current BWP is greater than the to-be-switched BWP, determining whether the terminal needs to switch the current BWP to the to-be-switched BWP according to the size relationship between the target BW andthe to-be-switched BWP and the service type of the target service; and when the current BWP is smaller than the to-be-switched BWP, determining whether the terminal needs to switch the current BWP tothe to-be-switched BWP or not according to the size relationship between the current BWP and the target BW.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method, device and system for switching a partial bandwidth of a terminal. Background technique [0002] In 5G technology, the emergence of bandwidth part (BWP) technology solves the problem of performance waste and high power consumption if all end user equipment (UE) use the maximum bandwidth. In BWP technology, UE does not need It supports all bandwidths and only needs to meet the minimum bandwidth requirements. When the UE traffic is not large, the UE can switch to low-bandwidth operation, which can reduce power consumption and reduce performance waste. Currently, in a new radio (NR) frequency division duplexing (FDD) system, a UE can be configured with up to four uplink (UL) BWPs and four downlink (DL) BWPs. In an NR time division duplexing (time division duplexing, TDD) system, one UE can be configured with up to four BWP pairs (Pairs). A UE...
