Abstract: Techniques for centralized control of peer-to-peer (P2P) communication and centralized control of femto cell operation are described. For centralized control of P2P communication, a designated network entity (e.g., a base station) may control P2P communication of stations (e.g., UEs) located within its coverage area. The designated network entity may identify a UE located within coverage of a femto cell but unable to access the femto cell due to restricted association. The designated network entity may deactivate the femto cell to allow the UE to communicate with another cell.

Abstract: Techniques for centralized control of peer-to-peer (P2P) communication and centralized control of femto cell operation are described. For centralized control of P2P communication, a designated network entity (e.g., a base station) may control P2P communication of stations (e.g., UEs) located within its coverage area. The designated network entity may receive an indication of a first station (e.g., a UE) desiring to communicate with a second station (e.g., another UE). The designated network entity may determine whether or not to select peer-to-peer communication for the first and second stations, e.g., based on the quality of their communication link. The designated network entity may assign resources to the stations if peer-to-peer communication is selected. For centralized control of femto cell operation, the designated network entity may control the operation of femto cells (e.g., may activate or deactivate femto cells) within its coverage area.

Abstract: To avoid or reduce intra-cell interference, each sector of a cell is associated with a sector-specific set of system resources (e.g., subbands) and at least one non-overlapping common set of system resources. Each common set for each sector includes system resources observing little or no interference from at least one other sector in the cell. The channel condition for a terminal in a given sector x is ascertained based on forward and/or reverse link measurements for the terminal. The terminal is assigned system resources from a common set or a sector-specific set for sector x based on the terminal's channel condition. For example, if the terminal observes high interference from another sector y, then the terminal is assigned system resources from a common set that observes little or no interference from sector y. The techniques may be used for an OFDMA system that uses frequency hopping.

Abstract translation: 为了避免或减少小区内干扰，小区的每个扇区与系统资源（例如子带）的扇区特定集合和至少一个不重叠的公共系统资源集合相关联。 每个扇区的每个公共集合包括观察到小区中至少一个其他扇区几乎或不受干扰的系统资源。 基于终端的前向和/或反向链路测量来确定给定扇区x中的终端的信道条件。 基于终端的信道条件，从通用集或针对扇区x的扇区特定集分配终端。 例如，如果终端观察到来自另一个扇区y的高干扰，则终端从公共集分配系统资源，其观察到来自扇区y的很少或没有干扰。 这些技术可以用于使用跳频的OFDMA系统。
