Abstract: Systems and methodologies are described that facilitate resource scaling for inter-access point fairness in a wireless communication system. As described herein, an offered load of an access point can be determined based on one or more loading metrics relating, to associated terminals, throughput, data rate, quality of service (QoS), or the like. Based on the determined offered load of an access point, resources used by the access point and/or power utilized for communication over those resources can be scaled based on a comparison of the offered load of the access point to a nominal or default offered load. Centralized techniques for resource scaling are described herein, wherein one or more centralized controllers coordinate resource scaling with respective access points via backhaul messaging. In addition, distributed techniques for resource scaling are described herein, wherein neighboring access points communicate with each other via over-the-air messaging to determine a local optimal resource apportionment.

Abstract: Se describen sistemas y metodologías que facilitan la escala de recursos para equidad de ínter-punto de acceso en un sistema de comunicación inalámbrica; tal como aquí se describe, una carga ofrecida de un punto de acceso se puede determinar con base en una o más métricas de carga relacionadas con terminales asociadas, salida, velocidad de datos, calidad de servicio (QoS), o similar; con base en la carga ofrecida determinada de un punto de acceso, recursos utilizados por el punto de acceso y/o potencia utilizada para comunicación sobre esos recursos puede ser escalada con base en una comparación de la carga ofrecida del punto de acceso a una carga ofrecida nominal o por omisión; aquí se describen técnicas centralizadas para escala de recursos, en donde uno o más controladores centralizados coordinan la escala de recursos con puntos de acceso respectivos a través de mensajería de retroceso; además, aquí se describen técnicas distribuidas para escala de recursos, en donde los puntos de acceso vecinos se comunican entre sí a través de mensajería sobre-el-aire para determinar una repartición de recursos óptima local.

Abstract: Techniques for transmitting data with distributed and centralized scheduling in a multihop relay communication system are described. For distributed scheduling, a relay station may generate and send first channel quality information (CQI) to a base station and receive second CQI from a subscriber station. The relay station may receive data sent by the base station based on the first CQI and may resend the data to the subscriber station based on the second CQI. For centralized scheduling, the relay station may generate first CQI for the base station, receive second CQI from the subscriber station, and send both CQIs to the base station. The relay station may receive data sent by the base station based on the first CQI and may resend the data to the subscriber station based on a scheduling decision determined based on the second CQI. Techniques for distributed and centralized power control are also described.
