Problems solved by technology

In the existing technology, the UE only measures and reports the channel state information of the activated BWP. Therefore, when the network switches the BWP, it can only randomly switch to other BWPs. The scheduling of the UE is relatively blind, and it is difficult to obtain a good frequency spectrum. efficiency, and may cause a sharp drop in UE throughput

Embodiment Construction

[0042] Those skilled in the art understand that, as mentioned in the background, there is currently a lack of technical solutions that facilitate BWP handover.

[0043] After careful study, the inventors of the present application found that in 3GPP Release 15, for one cell, the network can configure multiple BWPs (for example, 4 BWPs) for the UE. However, only one of them is an activated BWP, and the UE can only receive downlink control information (Downlink Control Information, DCI for short) of the network through the activated BWP, and receive and send data on the activated BWP. The network can trigger the UE to switch from the currently activated BWP to other BWPs through the DCI. At this time, the network may also schedule the UE to receive downlink data or send uplink data on the newly activated BWP through the DCI. The activated BWPs of different UEs may be the same or different.

[0044] However, in the existing mechanism, the UE does not measure and report the chan...

Abstract

A BWP switching method and device, storage medium, user equipment, and base station, wherein the BWP switching method includes: receiving first configuration information sent by the network, where the first configuration information is used to indicate measurement information of an inactive BWP; according to The measurement information measures the inactive BWP to obtain the channel state information of the inactive BWP; judges whether the channel state information of the inactive BWP satisfies the reporting condition; if the judgment result shows that the channel state information satisfies report condition, then send the BWP identifier of the inactive BWP to the network for the network to switch BWP. Through the technical solution provided by the present invention, when the network switches BWP, it can ensure that the throughput rate of the user equipment does not fluctuate greatly, and can obtain good spectrum efficiency and improve user satisfaction.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a BWP switching method and device, a storage medium, user equipment, and a base station. Background technique [0002] In the Fifth-Generation mobile communications (5G for short) new radio (New Radio, NR for short, also known as new air interface) technology, the cell bandwidth can be very large, up to 400MHz, far exceeding the current There is a cell bandwidth of 20 MHz in a Long Term Evolution (LTE for short) technology. If all user equipment (User Equipment, referred to as UE) directly accesses the 400MHz bandwidth when accessing the network, it will not only cause a high manufacturing cost of the UE, but also cause relatively large power consumption. Therefore, a new concept "BandwidthPart (BWP)" is introduced in 5G to allow NR UEs to use narrowband BWP to access the 5G system and use broadband BWP to transmit services. It can be seen that, after the...
