    摘要: A signal transmission method is provided, wherein, when a transmitter transmits a signal to a receiver, a transmitter processor multiplexes a plurality of data for a plurality of connections to be transmitted to one specific receiver, and constitutes a multiplexed medium access control (MAC) packet data unit (PDU) containing a MAC header part for receiving the multiplexed data, and a MAC PDU payload containing the multiplexed data, and the transmitter transmits the multiplexed MAC PDU to the specific receiver. The MAC header part includes a first header part containing a generic MAC header, and a second header part containing an extended header indicator serving as a 1-bit indicator for indicating the existence of an extended header (EH) for each flow ID for each of the plurality of connections. The MAC header part further includes a third header part which selectively contains the extended header for each flow ID in accordance with the extended header indicators for each flow ID.

    摘要: A closed-loop antenna switching method, a reference signal allocating method, and a feedback signal transmitting method for the same are disclosed. Namely, by transmitting a reference signal via the plurality of transmitting antennas via the antenna switching for reference signal transmission for each prescribed multiple period of an antenna selection period, efficient antenna index information can be fed back. By setting an antenna switching period to a prescribed multiple of an antenna selection period, it is able to prevent power loss and data decoding performance degradation. And, the present invention includes transmitting a sounding reference signal (SRS) for each band selection period via at least one of the plurality of transmitting antennas and transmitting at least one data demodulation reference signal (DMRS) between the band selection periods via an antenna for not transmitting data by reference signal transmission antenna switching.
