The method and apparatus include altering the direction of beams within cell sectors is among discrete angular positions according to a predetermined, cyclic pattern. The predetermined, cyclic pattern varies in a group of adjacent cell sectors such that inter-cell interference is significantly reduced or eliminated by rotating at a different cycle the beams in adjacent cells. This discrete, angular movement of beams provides for downlink transmissions to be timed in such a way (i.e., scheduled) such that transmission to a user will occur in accordance with the beam and time slot having the best carrier to interference (C/I) ratio for that user.

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： A method for reducing interference in a wireless system, and a system for performing the method. The wireless system should include at least two, and preferably four, beam formers and a plurality of mobile units. The method includes the steps of transmitting beams B1, B2, B3 and B4 into first, second, third and fourth beam areas, respectively. At least two sub-areas are defined within each of the first, second, third and fourth beam areas based upon the degree of overlap with adjacent beam areas, whereby each of the beam areas includes at least one overlapping sub-area and at least one non-overlapping sub-area. The method further includes coding signals of the beams B1, B2, B3 and B4 for receipt by a particular mobile unit based upon which one of the sub-areas that the particular mobile unit is located within.

摘要： In a wireless communications system, after a high data rate user is admitted and a supplemental channel is assigned to the user, a control message is sent to a receiver to communicate for power ramp-up and ramp-down profiles. The control message contains parameters of a data rate, a starting time and a duration of time as group in assigned fields in the message which is provided by a control signal source. In response to the control message, a controller provides a rate controllable signal with reference to the parameters of the control message to a data encoder. A bursty input data stream is fed to a buffer. The data encoder withdraws the data from the buffer in response to the rate controllable signal. The bit rate transitions in the bursty input data stream are smoothed with reference to the parameters. There is provided an output data stream having smoother data rate transitions than the input data stream. It is possible to solve problems with 3G CDMA systems which have sudden interference changes resulting from the bursty nature of high-speed data transmissions.
