摘要： Communication operations are optimally conducted by applying space-division multiple access in which wireless resources on a spatial axis are shared among a plurality of users. By applying an RD protocol to a communication system that conducts space-division multiple access, spatially multiplexed frames in a TXOP are made more efficient. By specifying a frame length for reverse direction frames with reverse direction permission information and having respective transmitters of reverse direction frames make their frame lengths uniform while respecting the specification, AGC operation stabilizes. Also, a transmit start time for reverse direction frames can be specified by reverse direction permission information, and respective transmitters of reverse direction frames can transmit frames at the same time while respecting the specification.

摘要： A terminal intermittently operates while receiving paging information and other necessary information from a base station. In the terminal cycles of DRX with different lengths are combined in a hierarchy manner to determine an intermittent operation period. Upper DRX in the hierarchy has a longer cycle than lower DRX. A period using a cycle of the immediately lower DRX is determined based on information on the cycle of the upper DRX. An intermittent operation of a communication processing unit is controlled based on information on the cycle of DRX in a period using information on a cycle of the lowermost DRX.

摘要： Even when the lengths of data items to be transmitted to users are not the same, the frames multiplexed at the same time finally have the same frame length and are transmitted.Even when the lengths of frames for the users are not the same at the time when a transmission request is received from a higher layer, a communication apparatus reconfigures at least two of the frames having short lengths into a frame having a long length through Aggregation so that the frames finally have the same frame length and transmits the frames at the same time in a multiplexed manner. On the transmitter side, the transmission power used per destination communication station can be increased due to a decrease in the total number of multiplexed frames. On the receiver side, an unstable AGC operation can be prevented.
