Problems solved by technology

[0004] In the CA scenario, as the demand for terminal services continues to increase, the data that the terminal needs to process continues to increase, and the power consumption is relatively large. Therefore, it is urgent to propose a method to reduce the power consumption of the terminal in the CA scenario.

Abstract

Embodiments of the present application provide a communication method and device, which relate to the field of communication technologies and can reduce terminal power consumption. The method includes: receiving information of one or more cell groups, wherein a cell group includes a first cell and at least one second cell, and for a cell group, according to the carrier bandwidth part BWP of the first cell in the cell group The handover or deactivation state determines the handover or deactivation state of the BWP of the second cell in the cell group. The method provided in the embodiment of the present application may be applied in a carrier aggregation scenario.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In the 5th Generation (5G) new air interface (new radio, NR), the base station can indicate the carrier bandwidth part (BWP) for the terminal, and then the base station and the terminal transmit data through the BWP . [0003] In order to further improve the throughput of the 5G system, carrier aggregation (CA) is introduced in NR, that is, multiple continuous or discontinuous spectrums can be aggregated and used. For each serving cell (cell), one or more BWPs may be configured for a terminal in the serving cell. Among them, the configured BWP can be a large bandwidth BWP, which is used to improve the service transmission capability of the terminal, and the configured BWP can also be a small bandwidth BWP, so that when the traffic volume is small, the terminal can reduce the data volume of radi...
