摘要： Pilot signal transmission sequences and methods are described for use in a multi-sector cell. Pilots in different sectors are transmitted at different known power levels. In adjacent sectors a pilot is transmitted while no pilot is transmitted in the adjoining sector. This represents transmission of a NULL pilot signal. A cell NULL is also supported in which NULL pilots are transmitted in each sector of a cell at the same time. Multiple pilot signal measurements are made. At least two channel quality indicator values are generated from measurements corresponding to at least two pilot signals of different power levels. The two values are transmitted back to the base station which uses both values to determine the transmit power required to achieve a desired SNR at the wireless terminal. The wireless terminal also reports information indicating its location to a sector boundary.

摘要： Methods and apparatus for collecting, measuring, reporting and/or using information which can be used for interference control purposes. Wireless terminals measure signals transmitted from one or more base stations, e.g., base station sector transmitters. The measured signals may be, e.g., beacon signals and/or pilot signals. From the measured signals, the wireless terminal generates one or more gain ratios which provide information about the relative gain of the communications channels from different base station sectors to the wireless terminal. This information represents interference information since it provides information about the signal interference that will be caused by transmissions from other base station sectors relative to transmissions made by the base station sector to which the wireless terminal is attached. Based on the signal energy measurements and relative gains generated from the energy measures, reports are generated in accordance with the invention and sent to one or more base stations.

摘要： A wireless terminal using OFDM signaling supporting both terrestrial and satellite base station connectivity operates using conventional access probe signaling in a first mode of operation to establish a timing synchronized wireless link with a terrestrial base station. In a second mode of operation, used to establish a timing synchronized wireless link with a satellite base station, a slightly modified access protocol is employed. The round trip signaling time and timing ambiguity between a wireless terminal and a satellite base station is substantially greater than with a terrestrial base station. The modified access protocol uses coding of access probe signals to uniquely identify a superslot index within a beaconslot. The modified protocol uses multiple access probes with different timing offsets to further resolve timing ambiguity and allows the satellite base station access monitoring interval to remain small in duration. Terrestrial base station location/connection information is used to estimate initial timing.

摘要： Methods and apparatus for using high power narrow signals, e.g., tones, for communicating transmitter information without putting the full transmission power available into the transmitted tone or tones are described. User data is transmitted in parallel with transmitter information in many embodiments with the user data being allocated more than 20% of the transmitter's maximum output power in many cases. Buy using an amount of power on the tones used to communicate transmitter information while simultaneously transmitting user data with more than 20% of the available transmission power, efficient bandwidth utilization is achieved while still ensuring a high probability that that the transmitter information signals will be received and detectable using simple energy detection techniques and without the need for timing synchronization with the transmitter to be achieved for success interpretation of the transmitter information.

摘要： Different NAK signals are used to indicate different relative levels of success in regard to an unsuccessful attempt to decode a received signal. An ACK signal (534) is used in the case of successful decoding. The device which generated and transmitted the original encoded signal receives the NAK signal (526,530) and selects a portion of redundant information, e.g. additional error correction bits, to be transmitted based on the value of the NAK signal. If the NAK signal indicates a low level decoding success indicating a relatively large number of errors in the decoded signal, a large set of redundant information is selected and transmitted. If the NAK signal indicates a relatively successful decoding, e.g. relatively few errors, a small set of redundant information is selected and transmitted. Where a small set of redundant information is transmitted new information can be transmitted with the redundant information.

摘要： Methods and apparatus for generating and transmitting frequency division multiplexed signals are described. The methods are well suited for use where a device uses a small subset, M, of a larger set of N subcarrier frequencies at any given time. Each transmitted FDM signal is generated by combining a plurality of individual analog subcarrier signals whose frequency may change, e.g., be hopped as a function of time. Each generated analog subcarrier signal is amplified, e.g., power amplified, and filtered prior to being combined with other analog subcarrier signals. Filters are used to compensate for or correct signal distortions and/or reduce interference between subcarriers. Fixed frequency filters are used in an exemplary frequency hopping OFDM system. In another embodiment, the filters are programmable and change, e.g., in terms of center frequency, to match the selected subcarrier frequency as frequency hopping occurs. The bandwidth of the programmable filters may remain constant.

摘要： First and second sets of information are transmitted using a relatively large transmission block including a plurality of minimum transmission units (MTUs), each MTU corresponds to a unique combination of resources. A first set of said MTUs is used in conveying said first set of information, said first set including at least a majority of said MTUs in the transmission block. A second set of said MTUs is defined, e.g., selected, for use in conveying said second set of information, said second set of MTUs including less MTUs than first set and at least some MTUs included in the first set. The first and second sets of information are communicated by transmitting at least some MTUs included in said first and second sets of MTUs with the corresponding information modulated thereon. The communicating of the information may be through superposition of the first and second information on shared MTUs.

摘要： Methods and apparatus for providing channel diversity to wireless terminals (WTs) in a manner that reduces the latency between the time a WT encounters satisfactory channel conditions are described. A plurality of communications channels with different physical characteristics are maintained in a cell by a base station (BS). Each WT monitors multiple channels and maintains multiple channel estimates at the same time so that rapid switching between channels is possible. Channel quality information is conveyed from each WT to the BS. The WT or BS selects a channel based on the measured channel quality. By supporting multiple channels and by introducing periodic variations into the channels in various embodiments, the time before a WT encounters a channel with good or acceptable channel conditions is minimized even if the WT does not change location. Multiple antennas are used at the BS to support numerous channels simultaneously, e.g., by controlling antenna patterns.

摘要： FDM signal communication methods and apparatus are described. In accordance with the invention FDM signals are generated in the time domain with symbols being mapped to specific point in time. Training symbols may be included in the transmitted FDM signal to facilitate symbol recovery. An exemplary receiver receives the FDM 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.
