摘要： A hybrid serial/parallel bus interface has a data block demultiplexing device. The data block demultiplexing device has an input configured to receive a data block and demultiplexes the data block into a plurality of nibbles. For each nibble, a parallel to serial converter converts the nibble into serial data. A line transfers each nibble's serial data. A serial to parallel converter converts each nibble's serial data to recover that nibble. A data block reconstruction device combines the recovered nibbles into the data block. The data block is employed by a gain controller.

摘要： A multi-mode wireless transmit/receive unit (WTRU) includes at least one antenna, first and second communication mode receivers and a first communication mode transmitter. The first and second receivers simultaneously receive signals from the antenna. The first transmitter generates and sends a first type of signal to the antenna while, at the same time, the second receiver receives a second type of signal from the antenna. In a preferred embodiment, the WTRU further includes a vector multiplier configured to reduce or eliminate interference of signals received by the second receiver, the interference being caused by the first transmitter. The vector multiplier adjusts the phase and amplitude of noise (i.e., spurious in-band noise) measured by the second receiver. The WTRU may further include a second communication mode transmitter configured to generate and send a second type of signal to the antenna.

摘要： Apparatus for reducing adjacent channel interference between proximate wireless communication units. Each wireless communication unit includes a digital baseband circuit and an analog baseband circuit. The digital baseband circuit includes at least one group delay compensation equalizer and at least one finite-impulse response (FIR) filter. The analog baseband circuit includes a radio (transmitter section), a power amplifier and a narrowband filter. The narrowband filter compensates for deficiencies of the power amplifier including distortion and radio frequency (RF) power spill over. The group delay compensation filter compensates for undesired characteristics (e.g., group delay variation) exhibited by the narrowband filter.

摘要： A method and apparatus for establishing a set of cells used to support a soft handoff. The apparatus is used in a wireless communication system including a plurality of cells and at least one wireless transmit/receive unit (WTRU) having at least one beam antenna which is configured to transition between a switch beam mode and an omni-directional beam mode. The WTRU communicates with a serving cell while the beam antenna is in the switch beam mode. The WTRU performs measurements on cells neighboring the serving cell to determine measurement results associated with the cells. The WTRU then determines whether each of the measurement results exceeds a predetermined threshold. A set of cells associated with the measurement results that exceed the predetermined threshold is established. If the number of cells in the set reaches a predetermined number, the beam antenna transitions from the switch beam mode to the omni-directional beam mode.

摘要： A method and apparatus for transmit power control (TPC) while switching a beam among a plurality of beams in a wireless communication system. An antenna array generates a plurality of directional beams and preferably an omni-directional pattern and switches a beam among the plurality of beams preferably including the omni-directional pattern. Link quality on at least one of the plurality of beams is measured, and a beam having a greatest link quality is selected. If the selected beam is different from a current beam, a beam is switched from the current beam to the selected beam. While switching a beam, TPC parameters are adjusted based on the link quality difference between the link quality of the current beam and the link quality of the selected beam, and optionally, base on other parameters.
