摘要： Spatial multiplexing and transmit diversity can improve the capacity of a wireless communication system. The system and method adapts communication schemes for communication systems with multiple antennas utilizing at least two transmission modes. The at least two transmission modes can, but are not necessarily, used for uplink communications. The two transmission modes may be chosen from the group consisting of a single antenna mode, a diversity mode a spatial multiplexed mode and a mixed diversity and spatial multiplexed mode. The at least two transmission modes may involve adaptation among multiple transmitters. At least one receiver may indicate a transmission mode to be used by a transmitter for a subsequent transmission. A transmitter may determine a transmission mode to be used for a subsequent transmission. The transmission mode can be based on channel sounding.

摘要： A transmission apparatus includes (N+1) or more transmission antennas. A first receiving apparatus detects N or fewer transmission antennas from a received signal. A second receiving apparatus detects more than N transmission antennas from a received signal. The transmission apparatus uses a first radio resource for outputting a known signal from each of transmission antennas and uses a second radio resource for outputting a known signal from at least one of the transmission antennas. A timing difference between the first and second radio resources is smaller than or equal to a first determined difference and a frequency difference therebetween is smaller than or equal to a second determined difference. The first receiving apparatus estimates a channel state based on the known signal outputted on the first radio resource. The second receiving apparatus estimates a channel state based on the known signals outputted on the first and second radio resources.

摘要： A new-part acquiring unit acquires a part of a block generated by a block generating unit, as a new part to be contained in a packet. A retransmission-part acquiring unit acquires a part of a block corresponding to a NAK as a retransmission part to be contained in a packet among blocks held in a retransmission buffer unit. An encoding unit groups a new part acquired by the new-part acquiring unit and a retransmission part acquired by the retransmission-part acquiring unit, and generates a packet. A modulating unit modulates a packet output from the encoding unit. A wireless processing unit performs a predetermined wireless transmission process to a modulated packet, and transmits a processed modulated packet via an antenna.
