摘要： Transmission techniques using configurable channels for the downlink and/or uplink are described. In one aspect, the downlink channel and/or uplink channel may be independently selected for a terminal. The terminal may establish a connection with a base station on default downlink and uplink channels. Another downlink channel and/or another uplink channel may be selected based on various factors such as channel quality, loading, and interference. The terminal would then switch to the new downlink and/or uplink channel for communication. In another aspect, the base stations broadcast sector information used by the terminals for communication and/or channel selection. The sector information may include various types of information such as the available downlink and uplink channels, the frequencies of the available channels, the loading on the available channels, and QoS information. The terminals may select a sector, a downlink channel, and/or an uplink channel based on the sector information.

摘要： OFDM signal communication methods and apparatus are described. In accordance with the invention OFDM signals are generated in the time domain with symbols being mapped to specific points in time. Training symbols may be included in the transmitted OFDM signal to facilitate symbol recovery. An exemplary receiver of the invention receives the OFDM signal from the communications channel, converts it into the frequency domain, and then filters it in the frequency domain to eliminate tones corresponding to other users. The filtered signal free of MAC interference is then converted into the time domain where channel estimation and compensation operations are performed. After channel compensation symbol recovery is performed in the time domain.

摘要： Methods and apparatus supporting peer to peer communications are discussed. A base station, serving as an access node for wireless terminals also communicates information supporting peer to peer communications. A base station transmits a beacon signal conveying information about a peer to peer frequency band and also receives user data from a plurality of wireless terminals, using the base station as a current point of network attachment. In some embodiments, the beacon signal is transmitted into the same frequency band being used for access node based communications and identifies a different frequency band which is to be used as a peer to peer frequency band. Alternatively, or in addition, in support of peer to peer communications, a beacon signal transmission apparatus, a free standing device which doesn't transmit user data, transmits a sequence of beacon signal bursts, each beacon signal burst including at least one high power beacon symbol.

摘要： A wireless terminal supports both peer to peer communications and access node based communications. The wireless terminal considers and evaluates communications link alternatives and selects between (i) communication using a peer to peer link and (ii) communications using a link, with a base station serving as an access node, Received signals corresponding to each of the link alternatives are used in performing link quality determinations. In one example, a received user beacon signal from a peer wireless terminal is the received signal used for the peer to peer link evaluation and a: base station beacon signal is the received signal used for the access node link evaluation. A link is selected as a function of quality determination, predicted data throughput, link maintenance energy requirements, and/or least cost routing determination information.

摘要： Methods and apparatus which allow a wireless terminal (302) to simultaneously maintain connections with multiple base stations (304, 306) are described. Each wireless terminal (302) is capable of supporting multiple separate timing and/or other control loops one, for each base station connection thereby allowing the connections to operate independently and in parallel. Different control signals and/or data are transmitted on each connection that is established with a base station (302, 306). In this manner base stations (302, 306) receive different data allowing for asynchronous data transmission. The data received by the base stations (302, 306) can be supplied to a wired asynchronous network (308) without the need to combine the received data prior to supplying it to the wired network (308). The communications techniques of the invention can be used to implement soft handoffs without the need to duplicate data transmissions to multiple base stations.

摘要： Methods and apparatus related to the sharing of wide area network (WAN) downlink bandwidth with peer to peer communication signaling usage are described. A WAN, e.g., cellular, wireless communications device using a base station attachment point, transmits a signal to be used by a peer to peer wireless communications device for controlling its peer to peer transmit power level. The peer to peer wireless communications device receives and measures the strength of the power control signal from the WAN wireless communications device. The measurement information is used by the peer to peer wireless communications device in determining whether or not peer to peer signal transmission is permitted and/or in determining a peer to peer transmission power level. Thus the WAN device is able to manage interference from the peer to peer devices in its vicinity which impacts its recovery of WAN base station downlink signals.

摘要： Methods and apparatus related to the sharing of wide area network (WAN) with peer to peer communication signaling usage are described. A mobile communications device receives a signal from a base station and measures a power of the received signal. The mobile communication device determines a transmission power level of a peer to peer reference signal as a function of the measured power of the received signal from the base station, wherein said function of the measured power of the received signal from the base station depends on a mobile target signal to noise ratio. The mobile communications device broadcasts the peer to peer reference signal at the transmission power level.

摘要： Methods and apparatus for supporting and using multiple communications channels corresponding to different transmit technologies and/or access technologies in parallel within a cell of a wireless communications system are described. Mobile nodes support multiple technologies and can switch between the technology being used at a particular point in time, e.g., from a first channel corresponding to a first technology to a second channel corresponding to a different technology which provides better transmission characteristics, e.g., a better perceived channel quality. Mobiles maintain at least two sets of channel quality information at any one point in time. Mobiles select the better channel and communicate the channel selection to the base station or communicate channel quality information for multiple channels to the base station and allow the base station to select the channel corresponding to the technology providing the better conditions for the mobile. Different mobiles in the same cell may support different technologies.
