Problems solved by technology

[0004] In view of this, the present invention provides a BWP switching method, terminal and network side equipment to solve the problem that after the terminal is switched to a new activated BWP, the network side cannot schedule the terminal because there is no measurement result of the new activated BWP. It is easy to cause data interruption and waste of power consumption.

Abstract

The invention provides a BWP switching method, a terminal and network side equipment. The BWP switching method comprises the steps that the BWP is switched; a BWP switching command sent by a network side device is received, wherein the BWP switching command is used for indicating the terminal to be switched to a target activation BWP, the BWP switching command carries indication information, and the indication information comprises BWP switching execution information and / or target activation BWP measurement information; and reporting the channel state information (CSI) of the target activatedBWP and / or switching the BWP according to the indication information. Thus, the terminal reports the CSI of the target activated BWP and / or executes the switching of the BWP according to the indication information. Therefore, the network side equipment can schedule the terminal after receiving the CSI report of the target activation BWP according to the indication information, the situation that the network side equipment cannot schedule the terminal due to no measurement result after the terminal is switched to the target activation BWP is avoided, and data interruption and power consumptionwaste can be effectively avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a BWP (BandWidth Part, partial bandwidth) switching method, terminal and network side equipment. Background technique [0002] In an LTE (Long Time Evolution, long-term evolution) system network, a carrier bandwidth of a cell is always smaller than or equal to a receiving bandwidth of a terminal (for example, 20 MHz). In NR (New RAT, a new wireless communication system), the carrier bandwidth on the network side can reach 400MHz, which is far greater than the receiving capability of the terminal. Therefore, in NR, in order to support the capability of the terminal, the concept of BWP is introduced. The concept of BWP is to divide the large bandwidth on the network side into multiple partial bandwidths, configure one or more BWPs of the serving cell to the terminal, and activate some of the configured BWPs to perform uplink and downlink transmission for the te...
