Abstract

A method of transmitting data in a wireless communication system supporting a multimedia broadcast/multicast service (MBMS) includes transmitting a data block for the MBMS through a main channel, and transmitting the data block through a sub-channel if an error report for the data block is received. Waste of radio resources is minimized by the use of a main channel while improving quality of the MBMS by restoring data by the use of a sub-channel.

Claims

1. A method of transmitting data in a wireless communication system supporting a multimedia broadcast/multicast service (MBMS), the method comprising:

transmitting a data block for the MBMS through a main channel; and

transmitting the data block through a sub-channel if an error report for the data block is received.

2. The method of claim 1, wherein the main channel is a common channel.

3. The method of claim 1, wherein the sub-channel is a dedicated channel.

4. A method of receiving data in a wireless communication system supporting a multimedia broadcast/multicast service (MBMS), the method comprising:

receiving a data block for the MBMS through a main channel;

transmitting an error report if an error is detected from the data block; and

receiving the data block through a sub-channel.

5. The method of claim 4, wherein the main channel is a multicast traffic channel (MTCH).

6. The method of claim 4, wherein the sub-channel is a dedicated traffic channel (DTCH).
