摘要： A method for transmitting and receiving a control channel message in a mobile communication system using multiple antennas is provided. A base station determines whether a common pilot is used or a dedicated pilot is used. It also determines whether a corresponding Multiple Input Multiple Output (MIMO) mode is a Multi-CodeWord (MCW) MIMO mode or a Single CodeWord (SCW) MIMO mode, and determines whether knockdown precoding is used or ready-made precoding is used. The base station generates a control channel message field including a pilot pattern and a precoding type according to the determination results, and transmits the generated control channel message to the terminal. The terminal receives a control channel message transmitted from a base station. The terminal determines whether a common pilot is used or a dedicated pilot is used, whether a corresponding MIMO mode is an MCW MIMO mode or an SCW MIMO mode, and whether knockdown precoding is used or ready-made precoding is used. The terminal analyzes the control channel message field according to the determination results, and determines a data reception method according to the analysis result.

摘要： A mapping method and an apparatus, which uniformly distribute bits included in transmission symbols to various resource blocks in mapping the transmission symbols to the resource blocks for transmission in an OFDMA mobile communication system. A sub-packet generator generates a sub-packet by selecting symbols from coded symbols including a first bit group and a second bit group, the first bit group having a different priority than the second bit group. A divider divides each bit group of the sub-packet into as many bit streams as previously allocated resource blocks. A resource block mapper maps the divided bit streams to the resource blocks, respectively, and outputs the bit streams for transmission.

摘要： In a wireless communication system a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that &; of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes˜results in failure of data recovery. In the present invention, in order to expand the coverage of the control channel to at least the coverage of the data channel, the time resource of the transmission resource wherein the control channel is transmitted is expanded and allocated for sending and receiving the control channel. By way of methods for extending the time resource are provided a method wherein a plurality of sub frames are used to transmit one control channel, and a method wherein a part of a data channel is used for the control channel.
