Abstract: When a wireless transmit receive unit (WTRU) is using a reduced dedicated physical control channel (DPCCH) frame, the WTRU may periodically send a normal DPCCH frame. The WTRU may periodically increase the transmit power or send a normal DPCCH frame if there is a transmit power control (TPC) error or a downlink quality is below a threshold. When the WTRU implements DPCCH transmission gating, the WTRU may set a gating period based on the number of received TPC commands. The WTRU or Node-B may restore to a normal mode, if the link quality is below a threshold. The WTRU may periodically increase a transmit power. When a reduced signal-to-interference ratio (SIR) target is used for TPC, the WTRU may increase a transmit power, if the downlink power is not responsive. The WTRU or the Node-B may restore a normal SIR target if the link quality is below a threshold.

Abstract translation: 当无线发射接收单元（WTRU）正在使用精简专用物理控制信道（DPCCH）帧时，WTRU可以周期性地发送正常的DPCCH帧。 如果存在发射功率控制（TPC）错误或下行链路质量低于阈值，则WTRU可以周期性地增加发射功率或发送正常DPCCH帧。 当WTRU实现DPCCH传输门控时，WTRU可以基于接收的TPC命令的数量来设置门控周期。 如果链路质量低于阈值，则WTRU或节点B可以恢复到正常模式。 WTRU可以周期性地增加发射功率。 当降低的信号干扰比（SIR）目标用于TPC时，如果下行链路功率不响应，则WTRU可以增加发射功率。 如果链路质量低于阈值，则WTRU或节点B可恢复正常的SIR目标。

Abstract: A method and apparatus for admission control based on Node-B measurements in a wireless communication system is disclosed. Once a call request is received, a code is selected among available codes for potential allocation. A target cell load and a neighbor cell load for each of available timeslots is calculated assuming additional allocation of the selected code to each of the timeslots using Node-B measurements.

Abstract: In a wireless local area network having an access point (AP) and at least one station, wherein data is prioritized by access categories, a method for admission control begins by calculating a transmission budget (102) for each access category (AC) and a total transmission budget for all ACs requiring admission control. A traffic stream admission request is sent from a station to the AP. A medium time value for the traffic stream is calculated at the AP (108), based on information extracted from the admission request (106). The medium time value is compared to the transmission budget for the AC corresponding to the traffic stream and the total transmission budget. The traffic stream is accepted if the medium time value is not greater than both the transmission budget for the AC corresponding to the traffic stream and the total transmission budget (110); otherwise, the traffÊc stream is rejected (112).

Abstract: A wireless communication system includes a plurality of wireless transmit/receive units (WTRUs) (110, 115, 120) and an access point (AP) (105). 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) 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.

Abstract: A startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.

Abstract: 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.

Abstract: Transmission power levels of uplink/downlink communication is controlled in a wireless communication system. A receiving station produces and provides to a transmitting station power control information based upon received signals from the transmitting station. A measured block error rate (BLER msr ) is obtained from the number of erroneous blocks in a sliding window of the last N received data blocks and SIR adjustments are set based upon the BLER msr and a target BLER (BLER target ). A target SIR of received signals is adjusted according to the SIR adjustments.
