摘要:
The present invention relates to a transmission device, a receiving device, an information transmission method, and an information receiving method in a wireless communication system, and a recording medium in which data of a codebook used for transmitting and receiving information is recorded.
摘要:
A wireless communication system uses a multiple-input multiple-output (MIMO) antenna in the transceiver mode. The system includes the technical features of a stage in which m bits of a first set of information is transmitted for a first pre-coding matrix (where m is an integer greater than 1), and a stage in which n bits of a second set of information is transmitted for a second pre-coding matrix (where n is an integer greater than 1 but less than n).

The present invention discloses a method and an apparatus for configuring a channel using diversity. The method for configuring a channel using uplink diversity according to one embodiment of the present invention comprises the following steps: converting k-bit of information to be transmitted into n-bit, which is an encoded bit, so as to transmit predetermined information from the channel; selecting m-bit from among said n-bit and permitting T-number of transmitting antennas to generate T-number of modulation symbols so as to transmit said m-bit; and transmitting said T-number of modulation symbols as channel symbols from said T-number of transmitting antennas. In the step of generating the modulation symbols, the T-number of transmitting antennas generate the T-number of modulation symbols using R-number of different resources from each other.

The present description relates to a wireless communication system and to a method for transceiving channel information through carrier aggregation, and a terminal and a base station using the method. The method described in the present description comprises: receiving channel information from a user terminal, and generating a sub-band group from one or more subbands contained in at least one or more component carriers; and receiving, from the user terminal, channel information for each of the sub-band groups through a control channel.

The present invention relates to a method for mapping and transmitting demodulation reference signal (DM-RS) and a communication terminal device, and more particularly to a method for mapping and transmitting DM-RS which uniformly maintains reception reliability of DM-RS for each layer in a process for transmitting different DM-RSs for odd-numbered layers.
摘要:
A transmitter includes a layer mapper and a precoder. The layer mapper is configured to map 2 codewords to 3 layers to output a mapped set of 3 symbols. A first codeword is mapped into one layer, and a second codeword is mapped into two layers. The precoder is configured to precode the mapped set of 3 symbols using a precoding matrix that distributes the mapped set of 3 symbols across 4 antenna ports so that each codeword is distributed across 2 antenna ports.
