    摘要: A list of candidate basic service sets (BSSs) or access points (APs) is included in a medium access control (MAC) message which is received at a wireless transmit/receive unit (WTRU). The list includes an identity of each candidate BSS or AP and a preference indicator which indicates an extent that the candidate BSS or AP is preferred for selection and whether the candidate BSS or AP shall not be considered for selection. A BSS or AP is selected by the WTRU using the list.

    摘要: A wireless multi-cell communication system, such as a time division duplex (TDD) system, includes at least one wireless transmit/receive unit (WTRU) and a plurality of base stations which broadcast beacon signals into a plurality of sectors of a cell of the system. Beacon channel acquisition performance is enhanced by reducing beacon channel mutual interference. Each of the base stations broadcasts a beacon signal into at least one of the cell sectors in a first time slot and to at least another one of the cell sectors in a second time slot different from the first time slot. The WTRU determines, at a particular position, which one of the beacon signals has the best signal quality, acquires the one beacon signal and establishes communications via the base station that generated the one beacon signal having the best signal quality.

    摘要: A method and wireless transmit/receive unit (WTRU) for utilizing channel control information associated with enhanced uplink (EU) transmission is disclosed. The WTRU receives information via radio resource control (RRC) signaling and receives downlink (DL) control information for at least EU transmission. The WTRU determines whether the DL control information is intended for the WTRU based at least upon a first forty bit specific code sequence and a second forty bit specific code sequence received in at least one time slot and determines whether the DL control information is the first type or the second type. The WTRU utilizes the DL control information of the first type or the second type for at least EU transmission on a condition that the DL control information is intended for the WTRU.

    摘要: The present invention is related to a method and system for transferring wireless transmit/receive unit (WTRU)-specific information to support enhanced uplink (EU) operation in a wireless communication system. A radio network controller (RNC) obtains WTRU-specific information, and transfers the WTRU-specific information to the Node-Bs. Each Node-B is configured to schedule uplink transmissions from a WTRU and utilizes the WTRU-specific information in operation of EU transmissions.

    摘要: A method and apparatus to improve the quality of control signaling based on signaling messages controlling speech or data transmission over an air interface between at least two Multi-User-Reusing-One-Slot/Voice Services Over Adaptive Multiuser Channels On One Slot (MUROS/VAMOS) capable wireless transmit/receive units (WTRUs). The WTRUs communicate with each other at the physical layer via signaling messages transmitted in control channels such as Slow Associated Control Channel (SACCH) and Fast Associated Control Channel (FACCH). Speech services are provided simultaneously over the same physical channel, and the Timing Advance (TA) and Power Command (PC) parameters of a WTRU are multiplexed in several occurrences of the SACCH or FACCH to increase the number of channel bits available for channel coding.

    摘要: Disclosed are multiple embodiments of method and apparatus to facilitate Multiple Users Reusing One Timeslot (MUROS) operation in wireless communications. A pair of wireless transmit/receive units (WTRUs) may be multiplexed onto a timeslot using a same pulse format. A WTRU may communicate on a network using MUROS technology both on the downlink (DL) and the uplink (UL), and may use a first pulse format on the DL and a second different pulse format on the UL. Pulse format support information to facilitate MUROS operation may be communicated between a network and a WTRU. The support information may be communicated in Radio Resource Control (RRC) messages. A network may allow for concurrent operation of WTRUs using different types of MUROS technology. For example, a network may include WTRUs using MUROS based on orthogonal sub-channels (OSC) while other WTRUs use MUROS based on an interference-canceling technology such as Downlink Advanced Receiver Performance (DARP) Phase I or Phase II.
