Problems solved by technology

However, while CRAN facilitates joint multipoint processing mechanisms by centralizing signal processing thereby relieving resources from otherwise performing processing near the RRH, this requires the network interconnecting the BBU and RRH to maintain very high bandwidth and very low latency

Embodiment Construction

[0021] As used herein, the term "node" is used to define a connection point, redistribution point or endpoint. A node may be an electronic device attached to a network and capable of creating, receiving or sending information through a communication channel or link. In general, nodes have the capability to be programmed or designed to recognize and process transmissions or to forward transmissions to other nodes.

[0022] As used herein, the term "essential node" is used to define a node within a communication network that may be defined as a pool of baseband units, a radio network controller, a base station controller, or the like. In some implementations, a base node may be a public device node.

[0023] As used herein, the term "edge node" is used to define an access point, base station, evolved Node B (eNB), Node B (Node B), transmission point, reception point, long-range radio Nodes such as the head end. In some implementations, an edge node may be a radio edge node. ...

Abstract

A method and system are provided for dynamically splitting a signal processing chain of multiple signal processing functions between an edge signal processor associated with an edge node and a common signal processor associated with a base node. may be based on at least a first parameter indicative of the current state of an input signal sent to an edge node or public device node, a current operating state or a configuration state of a communication network or a part of a communication network, or other factors that may affect signal transmission and / or processing parameter to determine the split point. Embodiments of the present disclosure can manage network resources more effectively by determining signal processing chain split points according to the current input signal state or the current network state. Furthermore, joint processing schemes such as CoMP can be deployed more efficiently.

Description

technical field [0001] The present disclosure relates to the field of telecommunications, and in particular to methods and systems for segmenting signal processing chains in wireless communication networks. Background technique [0002] A centralized radio access network (Centralized radio access network, CRAN) provides a communication infrastructure capable of supporting traditional wireless communication standards and future wireless communication standards. However, previous network architectures such as those used in Long Term Evolution (LTE) networks are based on the 3rd Generation Partnership Project (3GPP) rd Generation Partnership Project, 3GPP), each access point such as eNodeB has both an RF antenna and a baseband processing unit. The signal received by the RF antenna is processed by the baseband processing unit to obtain a baseband signal. While this provides a functional network, it can also result in expensive construction costs. In the CRAN architecture, the...
