摘要： A method and apparatus is provided that allows M transceivers to transmit/receive using M2N distinct beams using passive beam steering. This provides for the use of arbitrary narrow beams with a number of transceivers that is a fraction of the number of beams but ensures 360° coverage. In other words it permits significant improvements in the link budget with a minimal rise in the cost of the BS. The apparatus includes M distribution switches applied to 2N passive beam forming networks each coupled to M antennas. The method and apparatus are compatible with TDM in the downlink and TDMA in the uplink.

摘要： Methods and apparatus are provided for managing interference in a wireless backhaul network comprising a plurality of hubs, each hub serving a plurality of remote backhaul modules (RBM), using power control with a one-power-zone (OPZ) constraint. Each hub uses a transmit frame structure comprising a plurality of zones, each RBM is scheduled on a different zone, and the same power level is maintained across all zones within a transmit frame. Under the OPZ constraint, and for scheduling policies under which the number of zones assigned to each RBM is fixed, the power and scheduling sub-problems are decoupled. This enables power control independent of scheduling, using methods having lower computational complexity. Methods are disclosed comprising iterative function evaluation or Newton's method approaches based on a weighted sum-rate maximization across the network, which can be implemented in a distributed fashion. Some of the methods can be implemented asynchronously at each hub.
摘要翻译：提供了用于管理包括多个集线器的无线回程网络中的干扰的方法和装置，每个集线器使用具有单功率区（OPZ）约束的功率控制来服务多个远程回程模块（RBM）。每个集线器使用包括多个区域的发射帧结构，每个RBM被调度在不同的区域上，并且在发射帧内的所有区域上维持相同的功率电平。在OPZ约束下，对于分配给每个RBM的区域数量固定的调度策略，功率和调度子问题被解耦。这使得功率控制独立于调度，使用具有较低计算复杂度的方法。公开的方法包括基于跨网络的加权和率最大化的迭代函数评估或牛顿方法方法，其可以以分布式方式实现。某些方法可以在每个集线器上异步实现。
