Abstract: A method for validating radio resource control (RRC) messages begins by receiving a RRC message at a wireless transmit/receive unit (WTRU) from a radio access network. A determination is made at the WTRU whether the message is valid by applying a predetermined validation rule. The WTRU accepts the message if the message is valid. The WTRU rejects the message if the message is not valid. The message is rejected unless a new transport format combination set (TFCS) is provided, until the WTRU enters a CELL_DCH state, or both.

Abstract: A method and apparatus (10) for efficiently allocating and deallocating interleaved data stored in a memory stack. The apparatus includes a processor (22) and a memory (12) including at least one memory stack. The processor receives and interleaves a plurality of data blocks. Each data block is allocated for a particular transport channel (TrCH) and has a designated transmission timing interval (TTI). The processor stores the interleaved data blocks in the memory stack based on the TTI of each data block, such that a data block having a larger TTI is allocated to the memory stack earlier and deallocated from the stack later than a data block having a smaller TTI. In one embodiment, the memory includes a first memory stack for common/shared uplink channels, a second memory stack for dedicated uplink channels, a third memory stack for common/shared downlink channels, and a fourth memory stack for dedicated downlink channels.

Abstract: 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.

The switched beam antenna generates a plurality of antenna beams. A method for operating the communications device includes receiving signals from the plurality of transmitters operating within the WLAN, identifying the received signals comprising medium access control (MAC) information, and determining a quality metric for each received signal comprising MAC information (104). A transmitter is selected based on the quality metrics. The antenna beams are scanned for receiving from the selected transmitter the signals comprising MAC information. A quality metric (105) associated with each scanned antenna beam is determined.

Abstract: A wireless communication system, which supports enhanced dedicated channel (E-DCH) data transmissions, includes a wireless transmit/receive unit (WTRU) (102), at least one Node-B (104) and a radio network controller (RNC) (106). The WTRU includes a buffer (126), a data lifespan timer (124), a data retransmission counter (130), a hybrid-automatic repeat request (H-ARQ) process (128) and a controller (122). The timer establishes a lifespan for at least one data block stored in the buffer. If physical resources have not been allocated for a data block associated with a lifespan timer that is close to expiration, the WTRU sends an urgent channel allocation request. If physical resources have been allocated, the data block is prioritized for transmission with respect to other data blocks. The data block is discarded if the lifespan timer expires or if the WTRU receives feedback information indicating that the data block was successfully received by the Node-B.

Abstract: A method for initial downlink transmit power adjustment for non-real time services in a wireless communications network begins by estimating an initial downlink transmit power level for non-real-time services. The estimated power level is then compared with a threshold. A determination is made whether an increase in the estimated power level would affect neighboring cells. If an increase would not affect neighboring cells, then the initial downlink transmit power level is adjusted by a predetermined amount.

Abstract: A method and apparatus for optimizing the system capacity of an Orthogonal Frequency Division Multiplexing (OFDM) system that uses with Multiple-Input Multiple-Output (MIMO) antennas. In a receiver, a target quality of service (QoS) metric and reference data rate are set. The target QoS metric may be set to a predetermined value and/or may be adjusted dynamically with respect to packet error rate (PER) by a slow outer-loop control processor. The QoS of received signals are measured and compared to the target QoS. Depending on the comparison, the receiver generates a channel quality indicator (CQI) which is sent back to the transmitting transmitter. The CQI is a one or two bit indicator which indicates to the transmitter to disable, adjust or maintain data transmission rates of particular sub-carriers, groups of sub-carriers per transmit antenna, or groups of sub-carriers across all transmit antennas. At the transmitter, the transmitted data rate is disabled, adjusted or maintained. At the receiver, the target QoS metric and reference data rate are adjusted accordingly. This process is repeated for each data frame of each sub-carrier group.
