Abstract: A client station that communicates with an access point (AP) in a wireless local area network (LAN) includes a media access control (MAC) device that controls transitions between an active mode and a low power mode. A radio frequency (RF) transceiver communicates with the MAC device. After the MAC device transitions the client station to the active mode, the RF transceiver transmits data to the AP when at least one of the AP finishes transmitting directed data to the RF transceiver and the AP transmits a null data frame to the RF transceiver. The MAC device transitions the client station to the low power mode when the RF transceiver finishes transmitting data to the AP. The AP uses at least one of a random order and a rotating order to access the client station. The client station and the AP are implemented in a console gaming system.

When the query unit determines that name information is included with the call or a previous attempt was made to obtain the name information, the query unit effects onward routing of the call.

Abstract: In an indoor positioning system, for establishment of a cost sharing system, the positioning information transmission device does not directly transmit positional information but performs concealment and variablization on the device ID and transmits the concealed and variablized device ID. The positioning information management server stores and manages correspondence between the device IDs and positional information, and performs conversion from the device ID to the positional information in accordance with the correspondence. Further, the problem of conflict between concealed IDs upon concealment of positioning identification information by the positioning information transmission devices, which occurs when all the positioning information transmission devices use the same secret key, can be prevented. The system can be operated even when the bit length of the device ID is short.

Abstract: A cell identifier is indicated in a signal to be transmitted in a cellular communication system by selecting one of a number, M, of codes, wherein each of the codes has a length N of code symbols, and wherein the selected code is associated with the cell identifier. The selected code is transmitted as a number, N, of reference symbols. The M codes are orthogonal with one another over their length, N, of the code symbols and also over at least one subgroup of length L of the code symbols, wherein L<M. During cell search, whether to use all N reference symbols or one or more subgroups of the reference symbols to construct one of M possible orthogonal codes depends on what type of cell search is being performed.
