A communication method includes a transmission process multiplexing a transport channel for transmitting data from a high-order layer on a physical data channel and transmitting the multiplexed result to the fixed station, a status notification process notifying status information containing information on a transmission power headroom used for scheduling, and a transmission control process receiving the scheduling result and controlling the transmission process. The status information notification process includes notifying an index attached to each predetermined transmission power headroom level classified between upper and lower limit values of the transmission power headroom as the status information.

Abstract: In an adaptive array terminal, at least one of two antennas (ANT#1, ANT#2) is a movable antenna. A display unit (6) of the terminal displays reception levels of, or level difference between, the two antennas. Thus, it becomes possible for a user to adjust an angle of the antenna such that reception levels of the two antennas come closer to the same level. Alternatively, a control unit (8) of the terminal automatically adjusts the antenna angle so that reception level difference between the two antennas becomes not higher than a prescribed value.

Abstract: A repeater device may be utilized to enable forwarding extreme high frequency (EHF) communication between EHF-enabled wireless devices. The repeater device may utilize polarization isolation to prevent and/or reduce interference between received and transmitted EHF RF signals in the repeater device. The repeater device may utilize signal gain control to maximize the transmit signal strength while forwarding EHF RF signals to enhance and/or enable polarization isolation between received and transmitted EHF RF signals. Received Signal Strength Indicators (RSSI) may be utilize to measure signal strength of transmit and/or received EHF RF signals to enable performing signal gain control. The repeater device may utilize control connections to enable communicating with the EHF-enabled wireless devices to facilitate performing signal gain control at the repeater device. Non-EHF interfaces, for example Bluetooth, may be utilized to establish the control connections.

Abstract: A base station (BS) communicates with a mobile station (MS) through relay stations (RSs). In one exemplary reliable relay-associated transmission scheme, the BS transmits data to the RSs using multicast or unicast. From the received packets, each RS calculates its reliability value according to a reliability function, which it informs the MS. The BS then generates a reliability metric to identify the RSs that are considered reliable. The reliable RSs transmit their information to the MS under a cooperative multicast transmission mode. Meanwhile, the unreliable RSs overhear the transmissions between the reliable RSs and the target MS. If the MS is unable to receive information from reliable RSs, the unreliable RSs can join the cooperative transmission to provide a higher cooperative diversity gain to the target MS.

In particular, the illustrative embodiment enables standard “off-the-shelf” IEEE 802.11 and Bluetooth transceivers to work in a coordinated fashion in a single telecommunications terminal. In the illustrative embodiment, a Bluetooth transceiver gains access to a shared-communications channel from an IEEE 802.11 transceiver by requesting access, even if the access is not immediate. The technique disclosed is also applicable to communications protocols other than IEEE 802.11 and Bluetooth.
