Method and apparatus for transmitting indication in wireless communication system
A method and apparatus for transmitting an indication in a wireless communication is provided. A user equipment (UE) transmits a first indication indicating at least one of first information and second information, starts a timer, and transmits a second indication if the first information included in the first indication is changed while the timer is running.
1. A method for a user equipment (UE) transmitting an indication in a wireless communication, the method comprising:
transmitting a multimedia broadcast/multicast service (MBMS) interest indication indicating that the UE is interested to receive or no longer interested to receive an MBMS session, the MBMS interest indication including at least a list of interested MBMS frequencies or a MBMS priority; and
determining whether to start a timer based on a content of the MBMS interest indication,
wherein the timer is a prohibit timer that is used to prohibit for the transmission of the MBMS interest indication,
wherein the timer is started if the MBMS interest indication includes the MBMS priority and the timer is not started if the MBMS interest indication includes the list of interested MBMS frequencies, and
wherein the MBMS interest indication is selectively transmitted while the timer is running based on changes of the list of interested MBMS frequencies or the MBMS priority.
2. The method of claim 1 , wherein the MBMS priority indicates whether the UE prioritizes MBMS reception above unicast reception.
3. The method of claim 1 , wherein the MBMS interest indication is related to inter-frequency mobility.
4. The method of claim 1 , wherein the timer is configured by a timer value received from a network.
5. The method of claim 4 , wherein the timer value is received via system information or via a dedicated radio resource control (RRC) message.
6. The method of claim 1 , wherein the timer is set to a specific value.
7. A user equipment (UE) in a wireless communication, the UE comprising:
a radio frequency (RF) unit for transmitting or receiving a radio signal; and
a processor coupled to the RF unit, and configured for:
transmitting a multimedia broadcast/multicast service (MBMS) interest indication indicating that the UE is interested to receive or no longer interested to receive an MBMS session, the MBMS interest indication including at least a list of interested MBMS frequencies or a MBMS priority; and
determining whether to start a timer based on a content of the MBMS interest indication,
wherein the timer is a prohibit timer that is used to prohibit for the transmission of the MBMS interest indication,
wherein the timer is started if the MBMS interest indication includes the MBMS priority and the timer is not started if the MBMS interest indication includes the list of interested MBMS frequencies, and
wherein the MBMS interest indication is selectively transmitted while the timer is running based on changes of the list of interested MBMS frequencies and/or the MBMS priority.
8. The UE of claim 7 , wherein the MBMS interest indication is related to inter-frequency mobility.
9. The UE of claim 7 , wherein the MBMS priority indicates whether the UE prioritizes MBMS reception above unicast reception.
10. The UE of claim 7 , wherein the timer is configured by a timer value received from a network.
11. The UE of claim 10 , wherein the timer value is received via system information or via a dedicated radio resource control (RRC) message.
12. The UE of claim 7 , wherein the timer is set to a specific value.
