    Abstract: Briefly, in accordance with one or more embodiments, a pathloss gap between a downlink pathloss from a base station to a mobile station and an uplink pathloss from the mobile station to the base station is estimated. An initial offset value for uplink power control of the estimated pathloss gap is calculated based at least in part on said estimating. An offset value for an uplink data channel or an uplink control channel, or combinations thereof, is set based at least in part on the initial offset value. The pathloss gap for uplink power control is compensated using the set offset value.

    Abstract: A channel normally used to transmit acknowledgement of successful signal receipt and an indication of unsuccessful signal receipt is adopted to transmit power control information from a base station to a mobile station. The power control information can be encoded as a binary code where each value of the code is indicated by an acknowledgement or non-acknowledgement signal.

    Abstract: A method is disclosed to eliminate inter-cluster interference of user equipment located at the edge of a cluster of cells. The method operates by employing fractional frequency reuse (FFR) principles on clusters or combinations of cells in a wireless neighborhood, in which base stations in the cells coordinate their operations in a scheme known as coordinated multi-point transmission (CoMP). By using the FFR principles to single out edge users of the CoMP cluster, the method mitigates interference and increases throughput for the edge users.

    Abstract: In a wireless communications network, a wireless device may examine the received signal to determine the strength of the received signal, and also determine the level of interference and noise. If a retransmission is needed due to a message being incorrectly received, these factors may then be processed to estimate whether the probable cause of poor reception is interference from a neighboring network. If such interference is the likely cause, the retransmission may be changed to a different time and/or to different frequencies in a subsequent frame, so that the interference from the neighboring network is less likely to reoccur.

    Abstract: In various embodiments of the invention, a relay station in a wireless communications network may communicate with one or more subscriber stations at the same time and/or on the same frequency that the associated base station is communicating with another relay station in the same network. This contrasts with the conventional technique of devoting one time period or frequency exclusively to communications between the base station and the relay stations, and devoting another time period or frequency exclusively to communications between the relay stations and the subscriber stations.

    Abstract: Techniques are described that can be used to determine a transmitter power level of a mobile station based on spectrum efficiency gain and loss. Spectrum efficiency gain is measured for a home sector base station. Spectrum efficiency loss is measured for base stations other than the home sector base station. In one example, a base station transmits information such as noise plus interference level to a mobile station and the mobile station determines the transmitter power level. In another example, the mobile station transmits information such as preamble signal strength and preamble total signal strength to the home sector base station and the home sector base station determines the transmitter power level and instructs the mobile station to apply the determined transmitter power level.
