1. A method of switching a bandwidth part (BWP), comprising:
sending, by a base station, transmitter receiver point (TRP) configuration information, wherein the TRP configuration information indicates a master TRP configured by the base station, the master TRP is one of a plurality of TRPs configured by the base station; and
sending, by the base station, BWP switching information via the master TRP, wherein the BWP switching information is used to instruct switching to a target BWP,
wherein during a target time period subsequent to sending the TRP configuration information, other TRPs than the master TRP in the plurality of TRPs are disabled to allocate resource to a terminal, and in the target time period, only the master TRP allocates resource to the terminal and communicates with the terminal;
wherein the target time period is a time period from start of a timer to expiration of the timer, and the timer is started by the terminal when switching to the target BWP;
wherein the master TRP is further configured to, after sending the BWP switching information, send a BWP switching notification to the other TRPs than the master TRP in the plurality of TRPs, and the BWP switching notification is used to notify the other TRPs that the terminal switches to the target BWP.
