Monitoring multicast broadcast control information
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a notification of a change to multicast broadcast (MB) control information associated with at least one MB service to which the UE is subscribed, the MB control information being included in an MB control channel (MBCCH) scheduled by a physical downlink control channel (PDCCH) communication addressed to an MB radio network temporary identifier (MB-RNTI); and monitor one or more resources of the MBCCH to receive updated MB control information based at least in part on receiving the notification of the change to the MB control information. Numerous other aspects are provided.
1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled with the memory and operable to:
receive a physical downlink control channel message, scrambled by a broadcast radio network temporary identifier, that schedules a broadcast control channel and that includes a bitmap, each bit of the bitmap corresponding to one of a notification of a change to broadcast control information associated with a respective existing broadcast service or a notification of a start of a new broadcast service; and
monitor, associated with the bitmap, one or more resources of the broadcast control channel to receive updated broadcast control information.
2. A method of wireless communication performable by a user equipment (UE), comprising:
receiving a physical downlink control channel message, scrambled by a broadcast radio network temporary identifier, that schedules a broadcast control channel and that includes a bitmap, each bit of the bitmap corresponding to one of a notification of a change to broadcast control information associated with a respective existing broadcast service or a notification of a start of a new broadcast service; and
monitoring, associated with the bitmap, one or more resources of the broadcast control channel to receive updated broadcast control information.
3. An apparatus for wireless communication, comprising:
means for receiving a physical downlink control channel message, scrambled by a broadcast radio network temporary identifier, that schedules a broadcast control channel and that includes a bitmap, each bit of the bitmap corresponding to one of a notification of a change to broadcast control information associated with a respective existing broadcast service or a notification of a start of a new broadcast service; and
means for monitoring, associated with the bitmap, one or more resources of the broadcast control channel to receive updated broadcast control information.
