摘要： One embodiment of the present invention, file transfers are performed in a wireless communication network between a wireless transmit/receive unit (WTRU) and a location external to the WTRU for purposes of utilizing the data under predetermined conditions. In another embodiment, file transfer is performed by determining conditions for file transfer using the WTRU. The file transfer takes place subject to the determined conditions, and using the WTRU to automatically request the file transfer in response to the existence of the determined conditions.

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 unified dual-mode global system for mobile communication (GSM)/universal mobile telecommunication systems (UMTS) clock and a transceiver employing the unified GSM/UMTS clock are disclosed. A reference clock generates a reference clock signal and a local oscillator (LO) generates a LO signal based on the reference clock signal. A frequency divider selectively generates either a GSM clock signal or a UMTS clock signal by converting a frequency of the LO signal by a predetermined factor. Both the GSM clock signal and the UMTS clock signal are generated based on the common reference clock signal. The reference clock signal frequency may be a GSM fundamental frequency or a UMTS fundamental frequency. An interpolator and/or a decimator may be used for matching frequencies of UMTS baseband signal and the UMTS clock signal or frequencies of GSM baseband signal and the GSM clock signal.
