    摘要: The claimed subject matter relates to providing uplink data rate option information in an uplink traffic channel segment. A wireless terminal may indicate a data rate option being used for the segment via an energy pattern applied to the tone-symbols of the segment. To indicate a first data rate option, additional energy may be applied to a first set of tone-symbols of the segment. To indicate a second rate option, additional energy may be applied to a second set of tone-symbols of the segment, the second set being different from the first set. According to some aspects, each implemented energy pattern may be represented by a pattern, which has a slope (e.g., in a logical, pre-hopped representation of the channel segment), where some of the patterns have positive slope and some of the patterns have negative slope. The use of positive and negative slopes facilitates the representation of more data rate options than would be possible if only one type of slope (positive or negative) for the energy pattern were utilized.

    摘要: 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.

    摘要: The claimed subject matter relates to enabling antenna switching in a wireless terminal that has multiple receive antennas per receive chain via soft-demodulation and interleaving of concatenated code received in a strip channel. A coherent demodulation protocol may be performed to estimate an SNR for a first antenna during a first time period, and a non-coherent demodulation protocol may be utilized on the strip channel to estimate an SNR for at least one other antenna during a second time period. SNRs may be compared and the terminal may select the antenna with the highest SNR for a next transmission superslot.

    摘要: A wireless terminal includes an uplink rate option indicator in the same uplink channel segment with data, the rate option indicator providing transmission rate information about the data transmitted in the segment. The indicator value is represented by an energy pattern within the segment. Different energy patterns correspond to different indicator values. The number of indicator values is less than the number of possible uplink data rate options supported by the wireless terminal. A single indicator value represents different uplink data rate options, at different times, as a function of a received maximum data rate option and/or type of assignment message. The maximum data rate option and/or assignment message was transmitted by the same base station receiving the indicator value; therefore, there is no ambiguity between wireless terminal and base station as to the interpretation of the uplink data rate option indicator value with respect to an individual uplink segment.

    摘要: Downlink traffic channel data rate options and methods of indicating to a wireless terminal a utilized downlink data rate option are described. The downlink traffic channel rate option for a segment is conveyed using an assignment signal and/or a block in the downlink traffic channel segment which is not used for user data. Downlink segment assignment signals in some implementations allocate fewer bits for rate option indication than are required to uniquely identify each option. In some implementations low rate options, e.g., using QPSK, are uniquely identified via assignment signals. Higher rate options, e.g., using QAM16 modulation, are conveyed via the distinct information block in the downlink traffic segment using a first coding/modulation method. Still higher rate options, e.g., using QAM16, QAM64, or QAM256, are conveyed via the information block in the segment using a second coding/modulation method which is applied to the rate option information.

    摘要: 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.

    摘要: A stream of modulation symbols from a zero symbol rate (ZSR) coding/modulation module and a stream of modulation symbols from another type of coding/modulation module are input into an interweaver module. The interweaver module mixes the two input streams when assigning modulation symbols to be communicated in a segment. If a ZSR modulation symbol is non-zero, the ZSR modulation symbol is allocated a transmission position. If the ZSR modulation symbol is a zero modulation symbol, the modulation symbol from the other coding/modulation module is allocated the transmission position. The non-zero modulation symbols from the ZSR module are higher in power than the non-zero modulation symbols from the other module, thus facilitating detection and recovery.

    摘要: A device includes a zero symbol rate (ZSR) coding/modulation module and a second type coding/modulation module. Both modules generate modulation symbols to be conveyed using the same air link resources but with the non-zero ZSR symbols having a higher power level. The ZSR module generates a mixture of zero and non-zero modulation symbols. A ZSR modulation scheme communicates information using both the position of the non-zero modulation symbols and the phase and/or amplitude of the non-zero modulation symbols. Different ZSR schemes, implementing different ratios relating the number of zero symbols to the total number of symbols, can be associated with different low data rates while second module modulation schemes can be associated with different high data rates. Modulation symbols from two modules are in some embodiments, superimposed. In some embodiments, non-zero ZSR modulation symbols punch out second module modulation symbols which occupy the same air link resource.
