Problems solved by technology

[0006] The CSI may not be ideal because channel estimation is not ideal and there is a delay in transmitting the CSI
In CoMP, the CSI is propagated through the backhaul network with limited capacity, which leads to the loss and delay of CSI

Embodiment Construction

[0032] It should be understood at the outset that, although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but rather be within the scope of the appended claims and their equivalents Modified within the full range of .

[0033] Stochastic control / decision theory can be used to address the effects of non-ideal channel state information (CSI). In an embodiment, the optimal clustering and rate allocation problem is determined for a coordinated multipoint (CoMP) system with delayed CSI using a decision theory approach. When making cluster and rate allocation decisions, the base station (BS) sends the local CSI to the c...

Abstract

In one embodiment, method for controlling multiple wireless access nodes includes receiving, by a central controller from a base station (BS), a message indicating a channel state information (CSI) and determining a state transition function in accordance with the message. The method also includes determining a belief state in accordance with the state transition function and determining cooperation for a plurality of BSs including the BS in accordance with the belief state to produce a cooperation decision. Additionally, the method includes transmitting, by the central controller to the BS, the cooperation decision.

Description

[0001] This application claims prior application priority to U.S. non-provisional application No. 14 / 292483, filed May 30, 2014, entitled "A SYSTEM AND METHOD FOR CONTROLLING MULTIPLE WIRELESS ACCESS NODES," and Priority priority to U.S. Provisional Application No. 61 / 829469, filed May 31, 2013, entitled "Clustering and Rate Allocation for Uplink Coordinated Multipoint System Including Delayed Channel State Information," which The entire contents of both prior applications are incorporated by reference in this application. technical field [0002] The present invention relates to a wireless communication system and method, in particular to a cluster system and method. Background technique [0003] In wireless networks, there is an increasing demand for high data rates in order to support complex services, for example, cloud computing. Wireless systems employ more robust resource reuse, which leads to increased co-channel interference. In a heterogeneous network (HetNet), t...
