Adaptive duplexing method of dynamic bandwidth allocation in wireless communications system

Abstract

The invention relates to an adaptive duplexing method of dynamic bandwidth allocation in a wireless communications system. The steps which enable the adaptive duplexing method of dynamic bandwidth allocation in the wireless communications system to be achieved are as follows. (1). Unit bandwidths of uplink and downlink are confirmed according to long-term statistics of ratios of upstream rates and downstream rates in a zone. (2). All the upstream (downstream) rates are made into upstream (downstream) spots according to the upstream (downstream) unit bandwidth, and available spots of all the uplinks (downlinks) form upstream (downstream) frequency pools. (3). Users unit build a band requisition system, and apply for band bandwidth information from an adaptive rate management platform. (4). The adaptive rate management platform is built. One is to link and remove a business platform which accords with users bandwidth needs, and two is for business which is built. (5). Users unit apply for releasing spots, users unit send requirement for removing connection, and the spots are release timely. Adaptive duplexing method of dynamic bandwidth allocation in the wireless communications system achieves allocation of rate dynamic bandwidth, improves rate using efficiency, and solves non-symmetrical transmission and allocation of uplink and downlink.
