    摘要: A method and apparatus for receiving system information updates includes a wireless transmit receive unit (WTRU) receiving a system frame number. The WTRU also receives system information messages in a modification period. The modification period has a boundary determined by the system frame number. The WTRU receives system information change notification after a first modification change boundary and determines that the system information is valid until a second modification change boundary.

    摘要: A method and apparatus for supporting a random access using a random access channel (RACH) are disclosed. Each of a plurality of wireless transmit/receive units (WTRUs) sends a random access request to a base station on an uplink RACH preamble. A RACH Response, sent by the base station, is received by each WTRU. A control signal portion of the RACH Response indicates the location of the RACH Response message portion. The RACH Response control signal comprises multiple control channel elements (CCE), where each WTRU is allocated a respective CCE to provide its unique RACH Response control signal. The WTRU is configured to locate its intended CCE from among the multiple CCEs sent by the base station.

    摘要: A method and apparatus for receiving system information updates includes a wireless transmit receive unit (WTRU) receiving a system frame number. The WTRU also receives system information messages in a modification period. The modification period has a boundary determined by the system frame number. The WTRU receives system information change notification after a first modification change boundary and determines that the system information is valid until a second modification change boundary.

    摘要: Method and apparatus are disclosed for determining a physical uplink power level for transmissions on a physical uplink channel. In one embodiment, a random access channel (RACH) uplink message is transmitted. The RACH uplink message includes a RACH message power level and/or a downlink pathloss figure. A downlink message including a power offset value is received. The physical uplink power level is set for transmissions on the physical uplink channel based on the power offset value. In another embodiment, a RACH uplink message is transmitted and a downlink message including a relative power offset value is received. The physical uplink power level for transmissions on the physical uplink channel is then set based on the relative power off set value.

    摘要: A method for performing cell reselection first determines a current cell selection quality value. The cell selection quality value is compared to a predetermined threshold. Measurements of neighboring cells are taken if the cell selection quality value is less than or equal to the predetermined threshold. Measurements can be taken of intra-frequency cells, inter-frequency cells, and inter-radio access technology cells. If a neighboring cell is found that is better than the current cell based on the measurements, then the better neighbor cell is reselected to.
