Delivery of multicast and broadcast services concurrently with unicast data

摘要

Briefly, in accordance with one or more embodiments, user equipment receives unicast services from a first carrier of a primary serving cell and determines if Multimedia Broadcast and Multicast services (MBMS) services are available on a second carrier based at least in part on information in a broadcast carrier channel that indicates the second carrier or an identification (ID) of the second carrier. If MBMS services are available on the second carrier, the user equipment at least temporarily switches to the second carrier to receive the MBMS services. The user equipment may provide feedback to the network or the primary serving cell when it starts and stops receiving MBMS services, and then may switch back to the primary serving cell when MBMS services have ended or the user equipment no longer desires to receive MBMS services.

主权项

1. A user equipment (UE) configured to:
receive a system information block (SIB) from an evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (EUTRAN) indicating an identified carrier frequency on which Multimedia Broadcast Multicast Services (MBMS) services are available; inform the EUTRAN that the UE will receive MBMS services on the identified carrier frequency; and receive MBMS services on the identified carrier frequency indicated in the SIB, wherein the UE is configured to receive a message from the EUTRAN changing secondary serving of the UE to a cell providing MBMS services while the UE is receiving MBMS services.
