1. A method of controlling a bitrate of a user equipment (UE), the method comprising:
receiving bitrate control information including a first recommended bitrate medium access control (MAC) control element (CE) from a base station (BS);
changing a bitrate by a value determined based on the bitrate control information;
transmitting, to the BS, information notifying that the bitrate has been changed; and
communicating with another UE at the changed bitrate,
wherein the information notifying that the bitrate has been changed includes a second recommended bitrate MAC CE including a same identifier as an identifier of the first recommended bitrate MAC CE, and
wherein first recommended bitrate MAC CE and the second recommended bitrate MAC CE comprise information about whether the recommended bitrate MAC CE is to request or notify a change in bitrate.
