Abstract: A wireless transmit/receive unit (WTRLJ) 11 uses an oscillator providing accuracy for synchronized communications parameters in an active mode (Fig. 1 , WTRLJ 11), and operates at reduced power during a discontinuous reception (DRX) mode (Fig. 1 WTRU 12). A real time clock (RTC) 28 is used as the frequency standard during the reduced power operation, and a frequency adjustment is effected while the RTC 28 is used as the frequency standard. By effecting the frequency adjustment, the RTC 28 is able to be used as the frequency standard for substantial time periods, thereby reducing power consumption of the WTRU 12 during the DRX mode.

Abstract: A smart antenna steering algorithm performs a periodic re-scan at an end of a sustained use period and before a next sustained use period. During a sustained use period, a re-scan of the other antenna beams is not performed. The periodic re-scan is performed on alternate antenna beams that were selected when the preferred antenna beam was selected. The steering algorithm monitors a quality metric of the alternate antenna beams as well as a quality metric for the preferred antenna beam. If the quality metric of the preferred antenna beam is less than the quality metrics of anyone of the alternate antenna beams, then the alternate antenna beam corresponding to the quality metric having a higher value is selected for the next sustained use period.

Abstract: A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. An enhanced uplink medium access control (MAC-e/es) entity processes a received scheduling grant to calculate a serving grant. The MAC-e/es entity determines whether both a hybrid automatic repeat request (H-ARQ) process for scheduled data and scheduled data are available. If an H-ARQ process for scheduled data and scheduled data are available, the MAC-e/es entity determines whether a serving grant exists. The MAC-e/es entity calculates a remaining power based on maximum allowed power and restricts an E-DCH transport format combination (E-TFC) based on the remaining power. The MAC-e/es entity selects an E-TFC using the serving grant and generates a MAC-e protocol data unit. The MAC-e/es entity may process the received scheduled grant is at each transmission time interval or may store the received scheduled grant in a grant list until there is E-DCH data to transmit.

Abstract: A wireless communication method and apparatus for generating a scheduling grant based on a relative grant are disclosed. A wireless transmit/receive unit (WTRU) receives an absolute grant from a serving radio link set (RLS) and receives a relative grant from the serving RLS and at least one non-serving radio link (RL). The WTRU decodes enhanced dedicated channel (E-DCH) absolute grant channel (E-AGCH)E-AGCH signals to detect an absolute grant, and decodes E-DCH relative grant channel (E-RGCH)E-RGCH signals to detect at least one relative grant. The WTRU then calculates a serving grant based on the detected absolute grant and/or the relative grant(s). The relative grant may be detected by performing a hypothesis test on the E-RGCH signals. A multiple alternative hypothesis test is performed for detecting the E-RGCH signals from the serving RLS and a binary hypothesis test is performed for detecting the E-RGCH signals from the at least one non-serving RL. A reliability test may be further performed on the E-RGCH signals.

Abstract: A method and apparatus for selecting a serving cell/Node-B in a single carrier frequency division multiple access (SC-FDMA) system are disclosed. For intra-Node-B serving cell selection, a serving Node-B measures channel quality indicators (CQIs) of each subcarrier block in an uplink of each cell controlled by the serving Node-B and selects a new serving cell based on the CQIs. The serving Node-B reports the selected new serving cell to a wireless transmit/receive unit (WTRU). For inter-Node-B serving cell selection, each of a plurality of Node-Bs measures a CQI of each of a plurality of subcarrier blocks in an uplink transmission in each cell controlled by each Node-B and forwards the CQIs to a serving cell selection entity. The serving cell selection entity selects a new serving cell/Node-B based on the CQIs. The serving cell selection entity may be a centralized access gateway, a current serving Node-B or a WTRU.
