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 multimedia broadcast/multicast service (MBMS) interest indication indicating a long-term evolution (LTE) frequency, and if an in-device coexistence (IDC) interference is detected on the LTE frequency, the UE transmits updated MBMS interest indication excluding the LTE frequency.
1. A method for transmitting, by a user equipment (UE), an indication in a wireless communication, the method comprising:
transmitting a first multimedia broadcast/multicast service (MBMS) interest indication including information on a frequency;
detecting that an internal interference on the frequency is caused by Wi-Fi service of the UE;
determining which one of a MBMS service and the Wi-Fi service is to be prioritized, in response to the detecting;
excluding the information on the frequency from the first MBMS interest indication thereby generating a second MBMS interest indication without the information on the frequency, in response to the determining that the Wi-Fi service is to be prioritized since the MBMS service is not required anymore; and
transmitting the second MBMS interest indication without the information on the frequency.
2. The method of claim 1 , wherein the frequency is a long-term evolution (LTE) frequency.
3. The method of claim 1 , wherein the frequency is used to receive the MBMS service.
4. The method of claim 1 , wherein the internal interference is in-device coexistence (IDC) interference.
5. The method of claim 1 , further comprising transmitting an interference indication indicating that the frequency is unusable due to the internal interference.
6. The method of claim 5 , wherein the internal interference indication is an IDC indication.
