Abstract

A method of transmitting/receiving a data block is disclosed. In receiving at least one data block multiplexed to one physical channel, the present invention includes the steps of receiving control information for a data block transmission, checking whether there is a necessity for configuring a table having combination information of data block sizes internally, and configuring the table having the combination information of the data block sizes for a data block reception according to a result of the checking step. Accordingly, the present invention internally configures the CTFC information without receiving separate CTFC information, thereby facilitating the reception of data blocks.

Claims

1. A method of receiving data blocks through a plurality of higher level channels mapped to a lower level channel in a wireless communication system, the method comprising:

receiving a message comprising a data block size combination set parameter from a network;

defining a default set of data block size combinations if there is no data block size combination set parameter in the message; and

receiving the lower level channel using one of the block size combinations.

2. The method of claim 1, wherein each one of the data block size combinations is associated with only one of the plurality of higher level channels carrying a data block.

3. The method of claim 1, further comprising

defining a second set of data block size combinations if there is the data block size combination set parameter in the message.

4. The method of claim 1, wherein the plurality of higher level channels are primarily used for data traffic transmission.

5. The method of claim 1, further comprising the step of:

receiving data block size information for each of the plurality of higher level channels.

6. The method of claim 5, further comprising the step of:

receiving a number of the plurality of higher level channels from the network that defines the set of data block size combinations.

7. The method of claim 5, wherein the set of data block size combinations is defined by using the data block size information.

8. The method of claim 6, wherein the set of data block size combinations is further defined by using the number of the plurality of higher level channels.

9. The method of claim 1, wherein the data block comprises a transport block, the data block size combination comprises a transport format combination, and the set of block size combinations comprises a transport format combination set.

10. The method of claim 1, wherein the plurality of higher level channels comprises transport channels.

11. The method of claim 1, wherein the lower level channel comprises a physical channel.

12. The method of claim 1, wherein the data blocks provided through a plurality of higher level channels comprise point-to-multipoint service data.

13. The method of claim 1, wherein the step of receiving the lower level channel using one of the block size combinations further comprises:

receiving a data block size combination indicator from the network.

14. The method of claim 13, wherein the lower level channel is decoded by using one of the data block size combinations according to the data block size combination indicator.

19. The method of claim 1, wherein the default set of data block size combinations is defined by using the data block size information.

20. The method of claim 1, wherein the default set of data block size combinations is further defined by using the number of the plurality of higher level channels.

15. A method of communicating point-to-multipoint service control information for a wireless communication system, the method comprising:

defining a default set of data block size combinations for use in a user equipment for a point-to-multipoint service, wherein each one of the default set of data block size combinations is associated with a transport format of each transport channel;

providing the default set of data block size combinations to the user equipment; and

transmitting a data block size combination indicator from a network to the user equipment to allow the user equipment to receive point-to-multipoint service control information, wherein the transport format of the point-to-multipoint service control information is determined by associating the received data block size combination indicator with the default set of data block size combinations.

16. The method of claim 15, wherein each one of the data block size combinations is associated with only one of the plurality of higher level channels carrying a data block.

17. The method of claim 15, wherein a plurality of higher level channels are primarily used for data traffic transmission.
