Abstract
Provided are a method and an apparatus for providing point-to-multipoint transmission in a single cell in E-UTRAN. The method may include receiving system information for single-cell multi-transmission in a primary cell (PCell); determining whether to transmit a multimedia broadcast multicast service (MBMS) interest information message; and transmitting the MBMS interest information message, wherein the MBMS interest information message is determined to be transmitted when the terminal sets an RRC connection or when interest group communication service information of the previous interest information message, which the terminal transmitted last, has been changed.
Claims20
A method of receiving single-cell multi-transmission data by a user equipment (UE), the method comprising:
- receiving system information for single-cell multi-transmission in a Primary Cell (PCell);
- determining whether to transmit a Multimedia Broadcast Multicast Service (MBMS) interest information message;
- and
- transmitting the MBMS interest information message,
- wherein the MBMS interest information message is transmitted when the UE establishes an radio resource control (RRC) connection or when interest group communication service information of a previous interest information message, which the UE transmitted lastly, is changed.
A method of transmitting single-cell multi-transmission data by a base station, the method comprising:
- transmitting system information for single-cell multi-transmission in a Primary Cell (PCell);
- and
- receiving a Multimedia Broadcast Multicast Service (MBMS) interest information message from a user equipment (UE),
- wherein the MBMS interest information message is received when the UE establishes an radio resource control (RRC) connection or when interest group communication service information of a previous interest information message, which the UE transmitted lastly, is changed.
A user equipment (UE) receiving single-cell multi-transmission data, the UE comprising:
- a receiver configured to receive system information for single-cell multi-transmission in a Primary Cell (PCell);
- a controller configured to determine whether to transmit a Multimedia Broadcast Multicast Service (MBMS) interest information message;
- and
- a transmitter configured to transmit the MBMS interest information message,
- wherein the MBMS interest information message is transmitted when the UE establishes an radio resource control (RRC) connection or when interest group communication service information of a previous interest information message, which the UE transmitted lastly, is changed.
