1. A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive configuration information to configure a groupcast sidelink network, that includes the UE and two or more other UEs, to conduct groupcast sidelink communication in the groupcast sidelink network,
wherein the configuration information includes an indication of a plurality of bandwidth parts configured for the groupcast sidelink network to conduct the groupcast sidelink communication;
transmit or receive data based at least in part on the configuration information;
transmit a switching message, to the two or more other UEs, that indicates to switch from utilizing a first bandwidth part, of the plurality of bandwidth parts, to utilizing a second bandwidth part of the plurality of bandwidth parts; and
refrain from switching to utilizing the second bandwidth part unless respective confirmation messages from the two or more other UEs are received prior to an expiration of a timer associated with the switching message.
