摘要： A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determination is made whether there is a previously unsent packet at the base station. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if one of the buffers is non-empty. A packet is selected to be transmitted if there is a previously unsent packet or if both buffers are non-empty. The buffers are updated based on feedback received from the UEs.

摘要： A method and apparatus for compensating for phase noise of symbols spread with a long spreading code are disclosed. To compensate for the phase noise, a phase error estimate is generated from despread symbols with a short spreading code. A phase correcting phasor is applied to chip rate data before despreading the data with a long spreading code. A signal-to-interference ratio (SIR) on a common pilot channel (CPICH) may be calculated by spreading the data with a parent spreading code in an orthogonal variable spreading factor (OVSF) code tree and by combining symbols. Alternatively, a magnitude of the symbols may be used in estimating the SIR. The SIR of a channel using a short spreading code and an SIR of a channel using a long spreading code are measured. The SIR of the channel with the long spreading code may be compensated in accordance with a difference between degradation of the SIRs.

摘要： A method and apparatus for correcting symbols of a common pilot channel (CPICH) to generate an accurate signal-to-interference ratio (SIR) estimate in a wireless communication system are disclosed. In one embodiment, a non-stationary mean of a group of the CPICH symbols is estimated, the CPICH symbols are delayed, and the CPICH symbols are corrected by dividing the delayed CPICH symbols by the estimated non-stationary mean of the group of CPICH symbols. In another embodiment, a signal power estimate is generated based on the magnitude of CPICH symbols, a noise power estimate is generated by subtracting the signal power estimate from a total power estimate based on the magnitude of the CPICH symbols, and a SIR estimate is generated for symbols that have undergone a time varying gain by dividing the signal power estimate by the noise power estimate.

摘要： An adaptive equalizer including an equalizer filter and a tap coefficients generator used to process a sample data stream derived from a plurality of received signals is disclosed. The tap coefficients generator includes an equalizer tap update unit, a vector norm square estimator, an active taps mask generator, a switch and a pilot amplitude reference unit used to minimize the dynamic range of the equalizer filter. A dynamic mask vector is used to mask active taps generated by the equalizer tap update unit when an unmasked signal output by the equalizer filter is selected by the switch to generate an error signal fed to the equalizer tap update unit. A fixed mask vector is used to mask active taps generated by the equalizer tap update unit when a masked signal output by the equalizer filter is used to generate the error signal.

摘要： A method and apparatus for adaptively biasing a channel quality indicator (CQI) used for setting a configuration of communication between a transmitter and a receiver in a wireless communication system. The receiver sends a CQI and positive acknowledgement (ACK)/negative acknowledgement (NACK) messages to the transmitter. The ACK/NACK messages indicate the absence or presence of error, respectively, in a transmitted data packet. The CQI is derived from the signal-to-interference ratio (SIR) and the ACK/NACK messages. The transmitter calculates the block error rate (BLER) of the transmitted data packets based upon the ACK/NACK messages sent from the receiver. The transmitter compares the BLER of the transmitted data packets to a target BLER and biases the CQI based on the comparison in order to achieve the target BLER.

摘要： A method and wireless communication system for providing channel assignment information used to support an uplink (UL) channel and a downlink (DL) channel. The system includes at least one Node-B and at least one wireless transmit/receive unit (WTRU). The WTRU communicates with the Node-B via a common control channel, the UL channel and the DL channel. The WTRU receives a message from the Node-B via the common control channel. The message includes an indication of whether the message is intended for assigning radio resources to the UL channel or the DL channel. The WTRU determines whether the message is intended for the WTRU and, if so, the WTRU determines whether the message is for assigning radio resources to the UL channel or the DL channel. The WTRU takes an appropriate action based on whether the message is for assigning radio resources to the UL channel or the DL channel.

摘要： A method and apparatus for correcting the phase and gain of data associated with a constellation pattern of a plurality of received individual symbols. Each symbol is divided into real and imaginary symbol components. The signs of the real and imaginary symbol components of each symbol are determined and used as a basis for determining whether the symbol is associated with a first or third quadrant of the constellation pattern or a second or fourth quadrant of the constellation pattern. The absolute values of the real and imaginary symbol components are determined and used to create a first sum and a second sum. A phase adjustment value ? and a gain adjustment value G are derived from the first and second sums, and are used to create a complex number. Each of the received individual symbols is multiplied by the created complex number to provide corrected constellation pattern data.

摘要： A method for biasing signal-to-interference ratio (SIR) to generate channel quality indicator (CQI) includes measuring the packet error rate (PER) of a received signal and comparing the PER to a to the target PER to generate a correction term. The correction term is combined with the SIR estimation of a reference channel to generate a CQI. The CQI is reported to a transmitter to adjust signal configurations, such as code rate, modulation type, number of codes, power offset.

摘要： Disclosed herein is HARQ management, scheduling, and measurements, among other things, for cooperative communication. For example, methods herein may be used in situations wherein relaying or helping mechanisms may comprise the use of a relay node which is part of a fixed infrastructure or a relay node which may be a mobile wireless transmit/receive unit (WTRU). In said situations, a first transmission with first data is established between an evolved NodeB (eNB) and a WTRU. A second transmission with second data is established between a relay node (RN) and the WTRU. Said first and second data are combined for decoding. A single HARQ feedback for said first and second transmissions is sent from the WTRU to the eNB.

摘要： A method and apparatus for encoding and decoding high speed shared control channel (HS-SCCH) data are disclosed. For part 1 data encoding, a mask may be generated using a wireless transmit/receive unit (WTRU) identity (ID) and a generator matrix with a maximum minimum Hamming distance. For part 2 data encoding, cyclic redundancy check (CRC) bits are generated based on part 1 data and part 2 data. The number of CRC bits is less than the WTRU ID. The CRC bits and/or the part 2 data are masked with a mask. The mask may be a WTRU ID or a punctured WTRU ID of length equal to the CRC bits. The mask may be generated using the WTRU ID and a generator matrix with a maximum minimum Hamming distance. The masking may be performed after encoding or rate matching.
