摘要:
A method and corresponding apparatus are provided for network configuration selection in a wireless network comprising a plurality of nodes. A subset of the nodes are configured to simultaneously participate in a sounding process, in which a node of the subset omni-directionally transmits a predetermined signal and in which other nodes of the subset of nodes sample the predetermined signal as received by an omni-directional antenna array of that node. Measurement reports are received from the subset of nodes, each measurement report comprising a signal source angle and a received signal strength. A path loss is determined in dependence on each measurement report to generate a set of path losses covering a plurality of transmitter node receiver node pairs. Then a directional configuration is selected for a directional antenna of each node of the subset of nodes for data transmission in dependence on the set of path losses.

An antenna apparatus operates as a base station in a wireless network, with a method configuring a transmission beam within such antenna apparatus. The antenna apparatus has a rotatable antenna assembly employing selected transmission beam patterns, and a controller to rotate the antenna assembly altering its azimuth direction. During configuration mode, a sweep operation rotates the antenna assembly to selected azimuth directions. Quality metric determination circuitry determines, for each selected azimuth direction, a link quality metric for wireless terminals based on communication between the wireless terminals and the base station whilst the rotatable antenna assembly is at that selected azimuth direction. Transmission beam determination circuitry determines, from the link quality metrics determined for the wireless terminals at each selected azimuth direction, both a transmission beam pattern and an azimuth direction for subsequent communication with the wireless terminals. The antenna apparatus efficiently self-configures its transmission beam pattern and azimuth direction.

An apparatus and method are provided for controlling a wireless feeder network used to couple access base stations of an access network with a communications network, the wireless feeder network connecting a plurality of feeder base stations coupled to the communications network and a plurality of feeder terminals coupled to associated access base stations, each feeder terminal having a feeder link with a feeder base station, and the feeder links being established over a wireless resource comprising a plurality of resource blocks. The method comprises the steps of: allocating resource blocks for use by the plurality of feeder base stations and the plurality of feeder terminals to establish the feeder links, wherein the resource blocks are allocated between a centrally administered schedule in which each resource block is associated with a predetermined feeder link and at least one feeder base station administered schedule in which a set of resource blocks is associated with a predetermined feeder base station, the predetermined feeder base station being configured to implement the feeder base station administered schedule dynamically by using the set of resource blocks in dependence on current traffic requirements of the predetermined feeder base station; monitoring network traffic being carried by the feeder links to determine at least one characteristic of the network traffic; and re-allocating the resource blocks between the centrally administered schedule and the at least one feeder base station administered schedule in dependence on the at least one characteristic of the network traffic.
