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 unit 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： Efficient enhanced transport format combination (E-TFC) selection methods and apparatus support flexible radio link control (RLC) packet data unit (PDU) size and medium access control (MAC) layer segmentation. Methods for filling an enhanced medium access control (MAC-e) packet data unit (PDU) with data from logical channels as part of E-TFC selection are provided. In one embodiment, the E-TFC selection algorithm employs a single request from the MAC layer to the RLC layer to request the number of bits it is allowed to send for a logical channel to create enhanced MAC-e PDUs. In another embodiment, the MAC entity performs multiple requests to the RLC entity. In another embodiment, the MAC entity makes a single request to the RLC entity to create one or more enhanced MAC-e PDUs of a set size. A technique is also provided for maintaining a guaranteed bit rate (GBR) for non-scheduled data flows with variable-length headers.

摘要： Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message, in addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told, by the network. Techniques may be used to indicate a network provider's machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.

摘要： Systems and method for uplink feedback for multipoint transmission of high-speed downlink packet access (MP-HSDPA) that may improve downlink transmission efficiency and cell coverage. For example, Channel Quality Indicator (CQI) and/or Precoding Control Indicator (PCI) that may be calculated to accommodate the needs of coordinated dynamic network scheduling. Additionally, various frame structures may be generated for the uplink feedback that may carry multiple CQI and HARQ-ACK feedbacks from MP-HSDPA. The frame structures may also address asynchronous downlink transmissions between two cells. Moreover, HS-DPCCH power offset settings for both CQI and HARQ-ACK fields that may be modified and/or created to ensure reliable uplink feedback transmission.

摘要： A method and apparatus for use by a first transceiver, (e.g., wireless transmit/receive unit (WTRU), access point (AP), node) for adjusting the transmission rate of packets transmitted to a second transceiver based on signals the first transceiver receives from the second transceiver. In one embodiment, a transmission packet error rate (Tx PER) process is used to adjust the packet transmission rate. In another embodiment, a relative signal strength indicator (RSSI)-based process is used to determine the RSSI of packets received at the first transceiver from the second transceiver for adjusting the packet transmission rate. In another embodiment, transmission quality indicators are measured at the second transceiver and are sent to the first transceiver, which derives a new packet transmission rate therefrom. The Tx PER and RSSI-based processes may be used individually, in combination, or in conjunction with other processes.

摘要： A wireless communication system includes a plurality of wireless transmit/receive units (WTRUs) and an access point (AP). The AP communicates with the WTRUs via an antenna. In one embodiment, the AP configures the antenna to a wide beam configuration that covers a desired service area and transmits a Request-To-Send (RTS) control message. When the AP receives a Clear-To-Send (CTS) control message from one of the WTRUs, the AP determines optimal antenna settings for communication with the one WTRU. The AP configures the antenna to a narrow beam configuration and transmits at least one data packet to the one WTRU. When the AP receives an acknowledgement message indicating that the data packet was successfully received by the WTRU, the AP configures the antenna to the wide beam configuration. In another embodiment, the AP is configured to transmit and receive data packet fragments from the WTRUs and configure the antenna accordingly.

摘要： A method for admission control of control plane signaling requests includes receiving a signaling request. Upon receipt of the signaling connection request, a first determination is performed to determine whether to provide admission to common resources. When the first determination is negative, a second determination is performed to determine whether to provide admission to dedicated resources. When the second determination is negative, the signaling request is rejected. When the second determination is positive, the request is admitted to dedicated resources. When the first determination is positive, a third determination is performed to determine whether the quality of the signaling request is high or low. If the quality of the request is high, the signaling request is admitted to common resources. When the quality is low, a fourth determination is performed to determine whether to provide admission to dedicated resources. If the fourth determination is positive, the request is admitted to dedicated resources. If the fourth determination is negative, the request is admitted to common resources.
