    Abstract: PROBLEM TO BE SOLVED: To provide methods for paging in an HSDPA connected mode CELL_PCH or URA-PCH state.SOLUTION: A WTRU is configured: to select various PICH information that is broadcast by a base station by compiling a list of candidate PICHs, and selecting PICH information on the basis of the U-RNTI of the WTRU; and to receive paging messages on the basis of the selected PICH information. In one embodiment, a WTRU receives paging messages on the basis of a PICH, an HS-SCCH, and an HS-PDSCH. In another embodiment, a WTRU receives paging messages on the basis of a PICH and an HS-PDSCH. In both embodiments, a time delay parameter is used so that the WTRU may listen for either the HS-SCCH or HS-PDSCH for a period of time and return to a sleep mode if no paging message is received.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for efficient precoding matrix verification in a MIMO radio communication system.SOLUTION: A radio transmitting and receiving unit WTRU transmits a precoding matrix index PMI to an eNode B. The eNode B transmits a verification message including a PMI indicator indicating whether the PMI of the WTRU and the PMI of the eNode B are the same or not. If the PMI of the WTRU and the PMI of the eNode B are the same, the eNode B only transmits the PMI indicator, and if not, the eNode B transmits the PMI indicator and the PMI of the eNode B to the WTRU. The eNode B can transmit multiple PMIs at the same time, and can divide the PMIs into multiple groups. Accordingly, a PMI adequacy verification message can be signaled to the WTRU by use of control signaling or a dedicated reference signal.

    Abstract: PROBLEM TO BE SOLVED: To resolve problems that a hidden node situation would arise in a wireless LAN, resulting in degraded capacity, and that hidden nodes phenomena across BSSs may also occur, and that, for the optimization to work properly, coordination and adjustment between the WTRUs are needed to allow gathering all the required information at the node making the decision on the setting of the deferral parameters.SOLUTION: A deferral management method is implemented in a wireless local area network (WLAN) including an access point (AP) and a plurality of wireless transmit/receive units (WTRUs). The AP sends a deferral management capabilities request message to the WTRUs to determine the deferral management capabilities of the WTRUs. In response, each of the WTRUs sends a deferral management capabilities indicator message to the AP. The AP may also send a deferral management parameter set message to the WTRUs to indicate values for setting deferral management parameters. In response, each of the WTRUs may optionally send a deferral management parameter set execution confirmation message to the AP.
