摘要： A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when Eb/No measurements for served mobiles do not meet target Eb/No levels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target Eb/No levels in a centralized manner based on an overall system state so that only a limited number of target Eb/No levels are allowed to increase when frame erasures occur. By preventing a percentage of target Eb/No level increases, at least temporarily, when frame erasures occur, a percentage of power up-adjust commands are avoided. Therefore, a similar effect to that achieved by the modified RILPC is achieved. In accordance with still a further implementation of the present invention, the modified RILPC algorithm may be used in combination with the modified ROLPC algorithm to provide greater resistance to increased interference conditions.

摘要： A method for controlling access of a subscriber station to a wireless communications system facilitates the maintenance of a performance target of the reverse link and desired geographic coverage of the reverse link. The method for controlling access of a subscriber station to a wireless communications system includes measuring a first performance indicator and a second performance indicator for a reverse link associated with a subscriber station seeking access to a wireless communications system. A blocking threshold value is established based upon the measured second performance indicator and may be adjusted to allow more or less blocking based on any additional metrics that characterize the performance of the current subscriber stations. The decision to grant or deny access of the subscriber station to the wireless communications system is determined based on a comparison of the measured first performance indicator to the established blocking threshold value.

摘要： In a method for minimizing reverse link power control overshoot in a wireless communications system, the output power of a mobile station is detected to determine whether it falls outside a dynamic range of the mobile station. If outside the dynamic range, a new output power falling within the dynamic range is calculated and set, and the mobile station is instructed to transmit at the new output power.

摘要： An exemplary method of communicating includes multiplexing control signaling in a physical uplink control channel (PUCCH) onto a physical uplink shared channel (PUSCH) by puncturing PUSCH data with PUCCH control information using a uniform distribution of the PUCCH information within at least one resource block of the PUSCH data. One example includes using a first constant amplitude zero autocorrelation sequence (CAZAC) index on PUCCH for communicating CQI and ACK information together and using a second, different CAZAC sequence index for communicating CQI information alone or with NAK information or DTX. The used index provides an indication of whether ACK information is communicated. The used index also provides implicit DTX detection without additional processing.

摘要： A method and an apparatus for scheduling transmissions of a plurality of cells in a wireless communications system including one or more base stations is provided. The method comprises providing a set of virtual channels to enable an intra-cell transmission orthogonal to another transmission within each cell of the plurality of cells and inter-cell transmissions orthogonal to other transmissions across a cluster of cells associated with the one or more base stations. The method further comprises exchanging signaling messages between two or more base stations to coordinate scheduling of the intra-cell transmission with the inter-cell transmissions for the cluster of cells. For optimizing a parameter associated with scheduling of a plurality of users from a cluster of cells in a wireless communication system, an optimal power level for the parameter of each active user may be searched to maximize an indication of system capacity of the wireless communication system. This enables a coordinated jointly scheduling of the users active in the cluster of cells based on the optimal power levels such that the total interference within the cluster may be minimized to maximize the system throughput/capacity.
