摘要： A method and wireless multi-cell communication system for providing high speed downlink packet access (HSDPA) services (FIG. 1). The system includes a radio network controller (RNC) (105) in communication with a plurality of base stations (110, 115 and 120). The RNC sends a control signal (140A, 140B,and 140C) to at least one base station having a plurality of timeslots, e.g., in a time division duplex (TDD) system and/or frames including transmission timing intervals (TTIs), e.g., in a frequency division duplex (FDD) system assigned thereto for the establishment of HSDPA channels. The control signal indicates a maximum allowed HSDPA transmit power for each of the timeslots and/or TTIs. The base station (110, 115 and 120) sends a feedback signal (145A, 145B and 145C) to the RNC indicating the results of measurements of the power of the transmitted HSDPA timeslots and/or TTIs during a predetermined time period.

摘要： A method for improving the reliability of a channel quality indicator (CQI) (102, 106 Fig. 3) message in a wireless communications network begins with receipt of the CQI message. The CQI message is then decoded, and a decision metric value for each symbol in the CQI message is computed. A largest decision metric value and a second largest decision metric value for the CQI message are determined. The reliability of the CQI message can be determined by comparing the two largest decision metric values. This method may be applicable to high-speed downlink packet access in time division duplex, frequency division duplex, or other modes of transmission.

摘要： A method for handover a mobile unit (UE) from a first base station (BS1) to a second base station (BS2) in a wireless communication systems employing smart antenna technology. Following trigger events of a handover, the mobile station generates a physical signal sounding pulse transmitted by an isotropic antenna. The sounding pulse may consist of a common sequence of symbols or a specific sequence of symbols that uniquely identifies the mobile station. A series of sounding pulses can be sent according to a power ramping procedure until a base station has focused a communications beam toward the mobile. Receiving base stations provide feedback information upon detection of the sounding pulse allowing the mobile unit (UE) and/or base station (BS1-BS4) to form communication beams toward each other. A mapping protocol may also be utilized by the communication system.

摘要： Wireless mobile unit communication initiation is provided in a radio network that has a plurality of base stations, each providing wireless communication services in a respective geographic coverage. The wireless communication is established by first transmitting an omnidirectional sounding pulse from a wireless mobile unit. Information related to the detected sounding pulse is communicated to an interface by each base station detecting the sounding pulse. One of the base stations that detected the sounding pulse is selected for mobile unit communication based on the communicated information and directs a communication beam to the mobile unit to establish wireless communication. Alternatively, one or more of the base stations that detected the sounding pulse direct a communication beam to the mobile unit and the mobile unit selects the base station with which it is to establish wireless communication. Preferably, smart antennas, including directional beamforming capability, are employed by the base stations.

摘要： A wireless communication system having a Node B and a plurality of wireless transmit/receive units (WTRUs), includes a contention-based uplink (UL) channel and at least one downlink (DL) physical channel. The UL channel is randomly accessed by a WTRU when the WTRU is ready to transmit data. The DL physical channel supports DL transmissions from the Node B to the WTRUs. The DL transmissions include an acquisition indicator and information regarding said acquisition indicator. The acquisition indicator confirms whether the data transmitted over said UL channel was successfully received by the Node B.
