Abstract: Methods and apparatus for improving the utilization of air link resources in a wireless communications system, e.g., an OFDM MIMO system, including a base station with multiple transmit antennas are described. Superposition signaling in the downlink is employed. The superimposed signal includes a first transform result signal and a second lower power signal. The first transform result signal is generated from a first signal, which uses position modulation, e.g., including null components and high power non-null components. Different components of the first transform result signal are directed to different transmit antennas. The first transform result signal communicates information to a first wireless terminal, e.g., a weak receiver. The non-null received elements of the first transform result signal are utilized by a second wireless terminal, e.g., a superior receiver, as pilots to determine a channel estimate. The second wireless terminal uses the determined channel estimate to demodulate received second signals.

Abstract: Data communication over a block-coherent channel in a communication system is described. Low-complexity demodulation techniques that allow good performance are described. A dwell, e.g., a set of block coherent symbols transmitted including a known symbol, e.g., a pseudo pilot symbol, are received, demodulated and decoded by a joint decoder/demodulator employing soft inputs, soft outputs, and interleaving of messages. Low-complexity SISO demodulator is suitable for processing pseudo-pilot modulated information corresponding to each of one or more dwells. The low-complexity method achieves good performance when turbo equalization is used. Some decoding and demodulation embodiments include independent phase estimates and updated independent phase estimates following the extrinsic principle to generate soft symbol values and soft bits.

Abstract: Methods and apparatus related to assignment in a wireless communications system are described. A mobile is assigned an identifier and a mask value, e.g., as part of a state transition message. The mobile uses the assigned identifier and/or the assigned mask value in determining whether assignments included in assignment messages, e.g., traffic channel assignment messages, are directed to the wireless terminal. Predetermined associations between assignment slots, assigned segments, and/or mask values are utilized to limit control signaling overhead. Different groups of segments are available for assignment to different wireless terminals as a function of mask values. Different types of assignment messages use different amounts of information bits to convey the assignment. Some types of assignments use a wireless terminal identifier, while other types of assignments use a wireless terminal identifier and a mask identifier. The mask identifier, e.g., a single bit, allows for selection between a subset of the potential masks used in the system.

Abstract: In a first mode of dedicated control channel (DCCH) operation, a wireless terminal is allocated more segments than in a second mode. The wireless terminal uses different information bit to modulation symbol mapping in the different modes. On a per DCCH segment basis, the same number of modulation symbols are communicated in either mode but more information bits are conveyed in the second mode. Information bits for a DCCH segment are partitioned into two subsets. The two subsets are used to generate another set, each of the two subsets and the another set are input to the same mapping function to generate three equal size sets of modulation symbols which are transmitted via the DCCH segment. Uplink tone hopping is used such that one of the equal size sets of modulation symbols for the DCCH segment uses the same tone but a different set uses a different tone.

Abstract: Methods and apparatus for allocating and hopping tones for uplink communications purposes in adjacent sectors and neighboring cells of an OFDM system are described. Physical tones used in each sector and cell are allocated to tone hopping sequences according to a tone to tone hopping sequence allocation function which uses both a cell identifier and sector identifier. Different sectors and cells use different tone to tone hopping sequence allocation functions through the use of different cell and/or sector identifiers to minimize the number of collisions between hopping sequences of adjacent sectors and neighboring cells. Uplink tone hopping sequences, corresponding to logical tones are allocated to uplink communications channels. Uplink communications channels are used by wireless terminals, e.g., mobile nodes, to transmit data to base stations. Over time, a wireless terminal uses the tones included in the uplink tone hopping sequences corresponding to uplink communications channels it is authorized to use.

Abstract: Special DC tone treatment in a wireless communications system, e.g., an OFDM system, is discussed. In the downlink, a wireless terminal receiver introduces self-interference at the DC tone from the RF/baseband conversion. A base station every so often does not transmit on the downlink DC tone while continuing to transmit on other downlink tones. Wireless terminals measure received signal on the downlink DC tone during the time of suspended DC tone transmission, estimate self-interference and apply a correction to other received downlink DC tones. In the uplink DC tone interference is a composite of the assigned wireless terminal transmitter's baseband/RF conversion self-interference and air link noise. During one symbol interval of an N symbol interval dwell, the uplink DC tone is reserved for a special modulation symbol, which is a predetermined function of the other N-1 modulation symbols. At the base station, its receiver receives a set of modulation symbols conveyed by the uplink DC tone for a dwell, calculates the average DC component and corrects the received N-1 modulation symbols.

Abstract: A base station selects a maximum rate option indicator value for an uplink communications segment, e.g., uplink traffic channel segment, and transmits the selected indicator value, e.g., as part of the assignment message. The maximum rate option indicator value indicates to the wireless terminal a maximum allowed data rate option that the wireless terminal is permitted to use for the corresponding assigned uplink communications segment, the wireless terminal determining the actual uplink rate option used. Each uplink data rate option corresponds to: a number of information bits to be communicated in an uplink communication segment, a coding rate, and a modulation method. Some embodiments include multiple types of maximum uplink rate option indicators, e.g., a first type using a single bit and a second type using at least three bits. Different modulation methods are, in some embodiments, used for communicating the different types of maximum uplink rate option indicators.

Abstract: A wireless terminal receives an uplink traffic channel segment assignment including a maximum uplink rate option indicator. Each uplink rate option corresponds to a number of information bits, coding rate and modulation method. The maximum rate option indicator indicates the highest rate option that the wireless terminal is permitted to use when transmitting in the assigned traffic channel segment from the perspective of the base station. In some embodiments, the wireless terminal uses interference measurements to further quality, e.g., conditionally reduce, the maximum uplink rate option that may be used. Then, the wireless terminal selects an uplink rate option to use which is less than the determined allowed maximum uplink rate option, e.g., based on the amount of user data to communicate. The wireless terminal transmits data in the assigned uplink traffic channel segment in accordance with the wireless terminal selected uplink rate.
