Abstract

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus sends a message including an indication of at least one frequency of interest and at least one alternative frequency of interest. In an aspect, the at least one frequency of interest is used to provide a set of multimedia broadcast multicast service (MBMS) services and the at least one alternative frequency of interest is used to provide a subset of MBMS services of the set of MBMS services. The apparatus receives, for each MBMS service in the set of MBMS services, said each MBMS service using one of the at least one frequency of interest or the at least one alternative frequency of interest based on the message.

First claim

What is claimed is:

1 . A method of wireless communication of a user equipment (UE), comprising:
sending a message including an indication of at least one frequency of interest and at least one alternative frequency of interest, wherein the at least one frequency of interest is used to provide a set of multimedia broadcast multicast service (MBMS) services and the at least one alternative frequency of interest is used to provide a subset of MBMS services of the set of MBMS services; and receiving, for each MBMS service in the set of MBMS services, said each MBMS service using one of the at least one frequency of interest or the at least one alternative frequency of interest based on the message.

2 . The method of claim 1 , wherein the message is an MBMS interest indication message.

3 . The method of claim 1 , further comprising generating the message to include a frequency list including the at least one frequency of interest, and to include an alternative frequency list including the at least one alternative frequency of interest.

4 . The method of claim 3 , further comprising determining a priority for each frequency associated with the at least one frequency of interest and the at least one alternative frequency of interest, wherein the frequency list includes at least one frequency for each MBMS service in the set of MBMS services with a highest determined priority, and the alternative frequency list includes at least one remaining frequency for each MBMS service in the subset of MBMS services.

5 . The method of claim 4 , wherein the alternative frequency list includes at least two alternative frequencies of interest in order of the determined priority.

6 . The method of claim 4 , further comprising determining a quality indicator including at least one of a unicast reference signal received signal power (RSRP), a unicast reference signal received signal quality (RSRQ), a multicast broadcast single frequency network (MBSFN) RSRP, an MBSFN RSRQ, or any combination thereof, wherein the priority is determined based on the determined quality indicator.

7 . The method of claim 1 , further comprising generating the message to include a frequency list including the at least one frequency of interest and the at least one alternative frequency of interest.

8 . The method of claim 1 , further comprising:
determining a quality indicator including at least one of a unicast reference signal received signal power (RSRP), a unicast reference signal received signal quality (RSRQ), a multicast broadcast single frequency network (MBSFN) RSRP, or an MBSFN RSRQ, or any combination thereof; and sending a measurement report indicating the determined quality indicator, wherein said one of the at least one frequency of interest or the at least one alternative frequency of interest on which said each MBMS service is received is based on the measurement report.

9 . The method of claim 1 , wherein said one of the at least one frequency of interest or the at least one alternative frequency of interest on which said each MBMS service is received is based on loading conditions on one or more base stations from which each MBMS service is received.

10 . The method of claim 1 , further comprising:
determining a quality indicator including at least one of a unicast reference signal received signal power (RSRP), a unicast reference signal received signal quality (RSRQ), a multicast broadcast single frequency network (MBSFN) RSRP, an MBSFN RSRQ, or any combination thereof, for each of a plurality of frequencies, wherein the at least one frequency of interest includes one or more frequencies of the plurality of frequencies with a corresponding determined quality indicator greater than a threshold, and the at least one alternative frequency of interest includes one or more alternative frequencies of the plurality of frequencies with a corresponding determined quality indicator greater than the threshold.

11 . An apparatus for wireless communication, comprising:
a memory; and at least one processor coupled to the memory and configured to:
send a message including an indication of at least one frequency of interest and at least one alternative frequency of interest, wherein the at least one frequency of interest is used to provide a set of multimedia broadcast multicast service (MBMS) services and the at least one alternative frequency of interest is used to provide a subset of MBMS services of the set of MBMS services; and
receive, for each MBMS service in the set of MBMS services, said each MBMS service using one of the at least one frequency of interest or the at least one alternative frequency of interest based on the message.

12 . The apparatus of claim 11 , wherein the message is an MBMS interest indication message.

13 . The apparatus of claim 11 , wherein the at least one processor is further configured to generate the message to include a frequency list including the at least one frequency of interest, and to include an alternative frequency list including the at least one alternative frequency of interest.

14 . The apparatus of claim 13 , wherein the at least one processor is further configured to determine a priority for each frequency associated with the at least one frequency of interest and the at least one alternative frequency of interest, wherein the frequency list includes at least one frequency for each MBMS service in the set of MBMS services with a highest determined priority, and the alternative frequency list includes at least one remaining frequency for each MBMS service in the subset of MBMS services.

15 . The apparatus of claim 14 , wherein the alternative frequency list includes at least two alternative frequencies of interest in order of the determined priority.

16 . The apparatus of claim 14 , wherein the at least one processor is further configured to determine a quality indicator including at least one of a unicast reference signal received signal power (RSRP), a unicast reference signal received signal quality (RSRQ), a multicast broadcast single frequency network (MBSFN) RSRP, an MBSFN RSRQ, or any combination thereof, wherein the priority is determined based on the determined quality indicator.

17 . The apparatus of claim 11 , wherein the at least one processor is further configured to generate the message to include a frequency list including the at least one frequency of interest and the at least one alternative frequency of interest.

18 . The apparatus of claim 11 , wherein the at least one processor is further configured to:
determine a quality indicator including at least one of a unicast reference signal received signal power (RSRP), a unicast reference signal received signal quality (RSRQ), a multicast broadcast single frequency network (MBSFN) RSRP, or an MBSFN RSRQ, or any combination thereof; and send a measurement report indicating the determined quality indicator, wherein said one of the at least one frequency of interest or the at least one alternative frequency of interest on which said each MBMS service is received is based on the measurement report.

19 . The apparatus of claim 11 , wherein said one of the at least one frequency of interest or the at least one alternative frequency of interest on which said each MBMS service is received is based on loading conditions on one or more base stations from which each MBMS service is received.

20 . The apparatus of claim 11 , wherein the at least one processor is further configured to:
determine a quality indicator
