Abstract
An apparatus and method for multiplexing packets for broadcast services in a mobile communication system based on orthogonal frequency division multiplexing (OFDM). The OFDM system has a transmission structure in which one slot includes at least two symbols and each symbol includes a plurality of subcarriers. Different broadcast service packets received from at least two channels are multiplexed into one slot and a result of the multiplexing is transmitted. Overhead information of the channel packets multiplexed into the one slot is generated and transmitted.

Claim
1. A method for providing broadcast services in an Orthogonal Frequency Division Multiplexing (OFDM) system with a transmission structure in which one slot includes at least two symbols and each symbol includes a plurality of subcarriers, comprising the steps of:
multiplexing packets of different broadcast service into one slot, and transmitting the multiplexed packets; and
transmitting overhead information related to the multiplexed packets,
wherein the overhead information includes indicating information about whether the packets of the different broadcast service are multiplexed, first mapping information about symbol positions of the multiplexed packets when the packets of the different broadcast service are multiplexed, and second mapping information about subcarrier groups of the multiplexed packets when the packets of the different broadcast service are multiplexed.', 'multiplexing packets of different broadcast service into one slot, and transmitting the multiplexed packets; and', 'transmitting overhead information related to the multiplexed packets,', 'wherein the overhead information includes indicating information about whether the packets of the different broadcast service are multiplexed, first mapping information about symbol positions of the multiplexed packets when the packets of the different broadcast service are multiplexed, and second mapping information about subcarrier groups of the multiplexed packets when the packets of the different broadcast service are multiplexed.
2. The method of claim 1, wherein the multiplexing step comprises the step of:
assigning packets of one broadcast service to some symbols within the one slot, and assigning packets of another broadcast service to remaining symbols.', 'assigning packets of one broadcast service to some symbols within the one slot, and assigning packets of another broadcast service to remaining symbols.
3. The method of claim 2, wherein the one slot comprises four symbols, and the packets of the one broadcast service are assigned in a unit of two symbols.
4. The method of claim 1, wherein the multiplexing step comprises the step of:
assigning the packets of the different broadcast service to each symbol comprised in the one slot.', 'assigning the packets of the different broadcast service to each symbol comprised in the one slot.
5. The method of claim 4, wherein the packets of the different broadcast service assigned to each symbol are assigned to at least two grouped subcarriers.
