    摘要: 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 (BLERmsr) 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 BLERmsr and a target BLER (BLERtarget). A target SIR of received signals is adjusted according to the SIR adjustments.

    摘要: A method and apparatus which determine the minimum transmission power level of an access point (AP) for reliably communicating with at least one wireless transmit/receive unit (WTRU) in a wireless communication system. The apparatus obtains the range of the AP and estimates the interference to the AP by executing a slow interference estimation process and a fast interference estimation process. A required received power (RRP) of the WTRU is obtained from the interference estimate. The minimum transmission power level of the AP is determined by summing the range of the AP and the RRP.

    摘要: A method for seamless channel change in a wireless local area network having a station (STA) and an access point (AP) begins by sending a channel change intention message from the AP to the STA. A channel change response message is sent from the STA to the AP, informing the AP whether the STA will follow the channel change. The AP determines whether to proceed with the channel change, and performs the channel change if the determination is positive.

    摘要: During a contention-free period, or silent measurement period, of a first wireless communications channel, signals received on a second wireless communications channel are analyzed. The results of the analysis are used to perform advanced radio resource management functions, such as frequency selection, load balancing, or power management. Each of a plurality of wireless channels may be measured in order to perform the advanced radio resource management functions. During the analysis, an energy detect threshold may be lowered to a minimal value.

    摘要: A wireless transmit/receive units (WTRUs) receives a downlink transmission from a Node-B and decodes the downlink transmission. If the decoding is not successful, the WTRU sends a pre-defined burst signifying a negative acknowledgement (NACK) to the Node-B via a contention-based shared feedback channel. The pre-defined burst may be sent only once without requiring an acknowledgement. The Node-B calibrates a downlink transmit power so that the downlink transmission is transmitted to the WTRUs with a high likelihood. The Node-B may send a downlink transmission including multiple data streams processed using different modulation and coding schemes so that a WTRU having a high signal quality decodes all data streams while a WTRU having a low signal quality decodes less than all data streams. The Node-B sends a channel quality indicator (CQI) threshold so that each WTRU determines a data stream to report feedback based on the CQI threshold and a measured CQI.
