    Abstract: PROBLEM TO BE SOLVED: To allow a wireless terminal's receiver to remain on its current operating frequency band, and still identify the carrier frequency used by the neighboring sector or cell. SOLUTION: A base station sector transmitter in a multi-carrier wireless communication system transmits ordinary signaling, such as user data, in its own assigned band. In addition, the sector base station sector transmitter periodically transmits beacon signals into the frequency band used by adjacent sector transmitters for their ordinary signaling. Each beacon signal, being a short duration high power signal having the sector's transmission power and concentrated on one or a few tones, is easily detectable, and may be identified as to the source base station sector transmitter based on the tone. A mobile node, tuned to a single carrier band, receives a plurality of beacon signals, identifies the sources of the received beacons, compares the received intensity of the beacons, and makes handoff decisions, without having to switch carrier band.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage.SOLUTION: A base station regulates the level of interference from a peer to peer signaling by generating and transmitting peer to peer transmission power control signals intended for peer to peer wireless terminals in the local vicinity. A base station transmits, into a downlink frequency band, a signal, e.g., a beacon or broadcast channel signal, to be used by a peer to peer wireless terminal in controlling its peer to peer transmit power level into the corresponding uplink frequency band. The peer to peer wireless terminal receives and evaluates the base station signal. The determined information from the evaluation is used in determining whether or not peer to peer signal transmission is permitted and/or in determining a peer to peer transmission power level.

    Abstract: PROBLEM TO BE SOLVED: To provide a multi-mode base station having a transmission standby mode that is a low power/low interference level of operation.SOLUTION: A multi-mode base station includes a transmission standby mode and an active mode. Transmission standby mode (1322) of base station operation is a low power/low interference level of operation as compared to active mode. In transmission standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In the transmission standby mode, the base station may have some sleep state registered wireless terminals being serviced. Mode transitions (1320) from active to transmission standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmission standby to active may be in response to: scheduling information, access signals, wake-up signals, hand-off signals, wireless terminal state change signals, and/or base station mode change signals.

    Abstract: PROBLEM TO BE SOLVED: To provide methodologies that facilitate transmitting beacon symbols of a beacon message such that a sequence of symbols can satisfy a linear constraint over a field where the field elements can be identified with carriers.SOLUTION: A coding scheme can be applied to a beacon message; the coding scheme can produce a plurality of beacon symbols to transmit on given subcarriers. A receiving device of the beacon symbols decodes a beacon message by receiving less than the total number of symbols in a beacon message and determining the remaining symbol subcarriers based on the linear constraint. Thus, more efficient decoding of beacons is facilitated as well as resolving beacon ambiguity by figuring out which symbols satisfy linear constraints for the symbols, and resolving time and frequency shift by detecting an offset that would result in satisfaction of the linear constraint.
