    Abstract: Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

    Abstract translation: 描述了用于减轻跨越多个相邻覆盖区域的基本上相同的工作频带的无线通信系统中的小区间干扰的方法和装置。 操作频带可以在多个相邻或相邻的小区之间共享，例如在频率重用一个配置中。 无线通信系统可以跨多个基站同步一个或多个资源分配区域或区域，并且可以协调每个资源分配区域内的置换类型。 基站可以协调多个协调资源分配区域中的每一个中的导频配置。 可以基于干扰级别在协调的资源分配区域中为用户站分配资源。 订户站可以确定协调资源分配区域中的多个基站中的每个基站的信道估计以减轻干扰。

    Abstract: Systems and methods of pre-allocating identifiers to wireless devices for use in requesting resources over a random access channel are described. A wireless communication system includes a random access channel over which wireless devices can anonymously send requests for resources. The base stations receiving and processing the anonymous requests reduces the probability of random access channel collisions and conserves the resources needed to support the anonymous requests by pre-allocating one or more identifiers to select wireless devices. The wireless devices having the pre-allocated codes can transmit a particular code over the random access channel as a request for resources that uniquely identifies the requester.
