    摘要: A method of transmitting information necessary for performing collaborative multi input multi output (MIMO) operation between a mobile station and a base station in order to improve reception performance of the mobile station in a multi-cell environment is provided. The mobile station may receive a feedback channel for the collaborative MIMO which is allocated by a serving base station and transmit a collaborative MIMO indicator including information indicating that the collaborative MIMO is started to the serving base station. In addition, the mobile station may transmit the feedback information of each of the serving base station and a collaborative base station to the serving base station through the feedback channel, and the serving base station may transmit the feedback information to the collaborative base station via a backbone network. The mobile station may receive the collaborative MIMO supported by the serving base station and the collaborative base station.

    摘要: The present invention relates to a channel quality information transmission method in a communication system adopting a coordinated multi-point scheme. A terminal receives signals, through the same band, from a serving base station and at least one neighbor base station, respectively, which are included in a CoMP set operating in a joint processing mode. Next, the terminal generates combined channel quality information on a single signal obtained by combining the signals received through the same band, and then transmits the information to the serving base station. The combined channel quality information is generated using information on a combined channel obtained by combining channels between the terminal and the serving base station and between the terminal and each one of the at least one neighbor base station, which are included in the CoMP set.

    摘要: A method for releasing resources allocated by persistent scheduling is described. A base station (BS) inserts a persistent allocation release indication message into a control channel, wherein the persistent allocation release indication message includes at least one resource index indicating persistent allocation resources to a mobile station (MS), broadcasts the control channel, and releases the persistent allocation resources corresponding to the resource index. Since a release message for persistent allocation, a channel quality indicator channel, feedback polling allocation, etc. is inserted for transmission into a control channel which can be received by all MSs, overhead which occurs during resource release can be minimized irrespective of transmission rates varying with MSs.
