Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The minimum bandwidth of 5G can be 5MHz, and the maximum can reach 400MHz. If all UEs are required to support the maximum 400MHz, there will undoubtedly be higher requirements on the performance of the UE, which is not conducive to reducing the cost of the UE. At the same time, it is impossible for a UE to occupy the entire 400M bandwidth at the same time. If the UE adopts the sampling rate corresponding to the 400M bandwidth, it is undoubtedly a waste of bandwidth.

[0035] In the 5G NR system, the bandwidth of the UE can be changed dynamically. At the first moment, the UE has a large traffic volume, and the network side device configures a large bandwidth BWP1 for the UE; at the second moment, the UE has a small traffic volu...

Abstract

A method for adjusting bandwidth, a mobile terminal, a network side device, and a medium, the method comprising: based on a deactivation condition, deactivating a currently activated part of bandwidth BWP, where the currently activated BWP includes the currently activated BWP to be adjusted BWP; switch to the pre-configured default BWP. After adopting the embodiment of the present invention, bandwidth resources can be used reasonably.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for adjusting bandwidth, a mobile terminal, a network side device and a computer storage medium. Background technique [0002] In the new radio access technology (NR) system of the fifth generation (The 5th Generation mobile communication, 5G) communication system, a cell supports a system bandwidth of up to 400 megahertz (MHz), much larger than the long-term evolution (Long Term Evolution, LTE) maximum system bandwidth of 20MHz to support greater system and user throughput. [0003] However, supporting such a large system bandwidth will be a huge challenge for the realization of a User Equipment (UE). Therefore, the 5G NR system also supports dynamic and flexible bandwidth allocation, and divides the system bandwidth into multiple partial bandwidths (Bandwidth Part, BWP) to support the access of narrowband terminals or UEs in energy-saving mode. [0004] Currently, t...
