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 information through a plurality of higher level channels mapped to one lower level channel in a wireless communication system, the method comprising:

defining a default transport format combination set (TFCS) for the plurality of higher level channels mapped to the one lower level channel for use in a user equipment for a multimedia broadcast/multicast service (MBMS) by a predetermined manner, wherein the predetermined manner is predetermined between the user equipment and a network to include only transport format combinations (TFCs) used when a limited number of higher level channels among the plurality of higher level channels is transmitted via the one lower level channel if any information used for configuring the TFCS to be used for receiving the plurality of higher level channels mapped to the one lower level channel, including calculated transport format combination (CTFC) information, is not received from the network; and

receiving the one lower level channel with a transport format combination indicator (TFCI) defined by the predetermined manner between the user equipment and the network based on the default TFCS.

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

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

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

5. A mobile terminal for receiving data blocks through a plurality of higher level channels mapped to one lower level channel in a wireless communication system, the mobile terminal comprising:

an antenna for receiving the one lower level channel from a network a radio frequency unit connected to the antenna and configured to process the one lower level channel; and

a processor unit operationally connected to the radio frequency unit and being configured to;

define a default transport format combination set (TFCS) for the plurality of higher level channels mapped to the one lower level channel for use in the mobile terminal for a multimedia broadcast/multicast service (MBMS) by a predetermined manner, wherein the predetermined manner is predetermined between the mobile terminal and the network to include only transport format combinations (TFCs) used when a limited number of higher level channels among the plurality of higher level channels is transmitted via the one lower level channel if any information used for configuring the TFCS to be used for receiving the plurality of higher level channels, including calculated transport format combination (CTFC) information, is not received from the network; and

receive the one lower level channel with a transport format combination indicator (TFCI) defined by the predetermined manner between the user equipment and the network based on the default TFCS.

6. The mobile terminal of claim 5, wherein the plurality of higher level channels are primarily used for data traffic transmission.

7. The mobile terminal of claim 5, wherein the plurality of higher level channels comprises transport channels.

8. The mobile terminal of claim 5, wherein the lower level channel comprises a physical channel.
