摘要： The present invention provides cyclic power changing patterns for transmissions in different sectors of a cellular system. The cyclic power changing patterns define unique patterns in which transmission power levels change over a period of time slots or within a group of sub-carriers. Each sector has a unique pattern, so that interference information monitored by the user elements, which are supported by base stations, are indicative of the interference contributions from adjacent sectors. Based on these interference contributions and the cyclic power changing patterns associated with these sectors, the base stations can schedule transmissions to the user elements during time slots or in sub-carriers to minimize the impact of interference from the adjacent sectors and to efficiently support dynamic needs of the individual user data packets according to QoS requirements.

摘要： Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network. These embodiments can advantageously be deployed in dense urban areas and/or co-located with wireless access nodes, such as base-stations of a cellular wireless communication system. Preferably wireless links between constituent network nodes are set-up hierarchically. A basic result of this is that peer-to-peer (child-to-child) communication is generally prohibited and circuits are forced to conform to a topology. The multi-hop wireless backhaul network may be used to carry delay sensitive, high-density last mile circuit traffic over Non-Line-Of-Sight (NLOS) broadband radio links. Moreover, some embodiments of the invention provide a method of path-healing for re-routing of circuit traffic from circuits that have experienced catastrophic failures.

摘要： Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network, in particular an aggregation node (AGN). The AGN includes a plurality of spatially switched antennas and a transceiver configured to operate on the plurality of spatially switched antennas in a time divisional multiplexing (TDM) fashion to establish active connections with other network nodes in a hierarchical manner. The AGN is further configured to perform a bi-directional relay function for backhaul traffic with the other network nodes using at least one virtual circuit having an allocated bandwidth for delay sensitive traffic. The AGN may serve to aggregate and relay/amplify circuit traffic between network nodes in the up stream and down stream directions. If the AGN is interposed within a circuit between two other nodes, the AGN can switch the circuit traffic between the end-nodes of the circuit.
