초록 ▼

A method of transmitting a point-to-multipoint service in a mobile communication system, method of receiving the same, apparatus for transmitting the same and apparatus receiving the same are disclosed, by which a transmission parameter of a channel providing a point-to-multipoint service to a plurality of cells can be informed to UEs receiving the point-to-multipoint service. The present invention includes receiving at least one transmission parameter on a point-to-multipoint signaling channel providing scheduling information of the point-to-multipoint service wherein the point-to-multipoint signaling channel is mapped to the point-to-multipoint channel, combining the point-to-multipoint channel transmitted from a plurality of cells by using the at least one transmission parameter, and receiving the point-to-multipoint service on a point-to-multipoint traffic channel wherein the point-to-multipoint traffic channel is mapped to the point-to-multipoint channel.

대표청구항 ▼

1. A method of receiving a point-to-multipoint service at a mobile terminal in a mobile communication system, the method comprising: configuring a first channel providing scheduling information of the point-to-multipoint service by using configuring information received from a higher layer, wherein the configuring information includes a transmission power offset presence field indicating whether transmission power offset parameters are transmitted via the first channel;receiving, from a current cell, the transmission power offset parameters corresponding to each of a plurality of cells including the current cell via the first channel, only if the transmission power offset presence field indicates that the transmission power offset parameters are transmitted via the first channel;determining at least two cells among the plurality of cells based on the received transmission power offset parameters; andreceiving the point-to-multipoint service by combining second channels transmitted from the determined at least two cells,wherein the second channels provide the point-to-multipoint service. 2. The method of claim 1, wherein each of the transmission power offset parameters is an offset value between a transmission power of one of the second channels corresponding to one of the plurality of cells and a transmission power of a reference channel. 3. A receiver for receiving a point-to-multipoint service in a mobile communication system, the receiver comprising: a processing unit module for configuring a first channel providing scheduling information of the point-to-multipoint service by using configuring information received from a higher layer, wherein the configuring information includes a transmission power offset presence field indicating whether transmission power offset parameters are transmitted via the first channel; anda Radio Frequency (RF) module for receiving, from a current cell, the transmission power offset parameters corresponding to each of a plurality of cells including the current cell via the first channel, only if the transmission power offset presence field indicates that the transmission power offset parameters are transmitted via the first channel;wherein the processing unit module is further for determining at least two cells among the plurality of cells based on the received transmission power offset parameters,wherein the RF module is further for receiving the point-to-multipoint service by combining second channels transmitted from the determined at least two cells, andwherein the second channels provide the point-to-multipoint service.
