    摘要： A method and an apparatus for sending a signal on a contentious feedback channel for a downlink shared service and for estimating a number of wireless transmit/receive units (WTRUs) are disclosed. When a transmission criterion associated with a physical random access feedback channel (P-RAFCH) is satisfied, a physical resource is randomly selected among a plurality of physical resources assigned for the P-RAFCH and a pre-configured signal is sent using the selected physical resource. A Node-B receives the pre-configured signal from a plurality of WTRUs and calculates a number of the WTRUs based on a number of used physical resources. The transmission criterion is at least one of successful reception of a data packet on a downlink physical channel, successful reception of a data block on a data service, reception of a signaling command, occurrence of a measurement event, and failure to receive a transmission after a specified number of times.

    摘要： A method and apparatus are provided for performing information-theoretically secure cryptography using joint randomness not shared by others. Two valid communicating entities independently generate samples of a shared source that is not available to an illegitimate entity. The shared source may be a satellite signal, and each legitimate entity may generate uniformly distributed samples from a binary phase-shift keying signal received on an independent channel. Alternatively, the shared source may be a channel between the two legitimate entities, such that each legitimate entity generates samples of unknown distribution based on the channel impulse response of the channel. One legitimate entity generates an encryption key, a quantization error, and a syndrome from its samples. The quantization error and the syndrome are reported to the other legitimate entity. The other legitimate entity generates a matching encryption key using its samples, the quantization error, and the syndrome.

    摘要： Data estimation is performed in a wireless communication system using both oversampling and multiple reception antennas. A receive vector is produced for each antenna at a sampling interval which is a multiple of the chip rate of the received signal. A channel response matrix is produced for each antenna at a preferred multiple of the sampling rate. Each receive vector is processed using a sliding window based approach, where a plurality of successive windows are processed. For each window, a combined circulant channel response matrix is produced using the channel response matrices. Using the combined circulant channel response matrix and a combined received vector comprising each received vector in a discrete Fourier transform based approach to estimate a data vector corresponding to that window; and combining the data vector estimated in each window to form a combined data vector.

    摘要： A receiver or an integrated circuit (IC) incorporated therein includes a fast Fourier transform (FFT)-based (or hybrid FFT-based) sliding window block level equalizer (BLE) for generating equalized samples. The BLE includes a noise power estimator, first and second channel estimators, an FFT-based chip level equalizer (CLEQ) and a channel monitor unit. The noise power estimator generates a noise power estimate based on two diverse sample data streams. The channel estimators generate respective channel estimates based on the sample data streams. The channel monitor unit generates a first channel monitor signal including truncated channel estimate vectors based on the channel estimates, and a second channel monitor signal which indicates an approximate rate of change of the truncated channel estimate vectors. The FFT-based CLEQ generates the equalized samples based on the noise power estimate, one-block samples of the first and second sample data streams, the channel estimates and the monitor signals.

    摘要： A sliding window based data estimation is performed. An error is introduced in the data estimation due to the communication model modeling the relationship between the transmitted and received signals. To compensate for an error in the estimated data, the data that was estimated in a previous sliding window step or terms that would otherwise be truncated as noise are used. These techniques allow for the data to be truncated prior to further processing reducing the data of the window.
