Abstract: Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.

Abstract: There is provided a wireless device configured to perform both multi-user spatial multiplex communication and single user communication with a communication device. The wireless device is configured to set a first waiting time for the single user communication, and count the first waiting time in a period in which a second waiting time for the multi-user spatial multiplex communication is counted. The wireless device then transmits data through the single user communication after the first waiting time expires.

Abstract: An information processing apparatus includes a control unit. The control unit controls transmission of an inducement frame for causing another communication device to transmit a transmission suppression period reduction frame for reducing a transmission suppression period. In addition, the control unit controls transmission of the transmission suppression period reduction frame on the basis of the inducement frame in a case where the control unit receives the inducement frame. Transmission suppression periods set in other information processing apparatuses are equally reduced to eliminate inequality in using wireless resources.

Abstract: An information processing device includes a control unit. A first device that transmits data to the information processing device has a multiplexing function for multiplexing and transmitting data from a plurality of devices including the first device to the information processing device. The control unit provided in the information processing device performs control to tell the first device having the multiplexing function a multiplexing method for notification information and presence of data addressed to the first device. The notification information indicates that the first device has shifted from a functional suspension state to a data receivable state. The information processing device can reduce power consumption.

Abstract: A method of operating a base station in a wireless telecommunications system. Downlink communications from the base station to terminal devices are made using a plurality of OFDM sub-carriers spanning a system frequency bandwidth. The base station supports communications with a first type of terminal device on a host carrier using OFDM sub-carriers distributed across the system frequency bandwidth and supports communications with a second type of terminal device on a restricted bandwidth carrier using OFDM subcarriers distributed across a restricted frequency bandwidth which is smaller than and within the system frequency bandwidth. Respective base stations can exchange information regarding their restricted bandwidth carrier transmissions to help them coordinate their respective transmissions with a view to reducing intercell interference.
