摘要： A method and apparatus for increasing system capacity in a mixed-rate wireless communication are disclosed. Improvements are obtained using multiuser detection or antenna array processing techniques or both to explicitly cancel or attenuate only the high power users. Multiuser detection may be combined with antenna array processing to recover capacity appropriated by the high-power users. By mitigating the interference effects of only the high-powered users, the computational burden is manageable. An antenna array algorithm or a multiuser detection algorithm or both, are applied only to n high rate users (n

摘要： Multiple microcell base stations are located within a macrocell having single macrocell base station in an hierarchical architecture, and microcell users (&mgr;-users) and macrocell users (M-users) communicate respectively with the &mgr;-base and the M-base using the same frequency band, by appropriately (a) selecting the ratio of the radius r of each &mgr; cell and the average distance d from the M-base (r and d are measured by the “radio distance”, which includes the effects of shadowing), and (b) controlling the power level with which uplink (mobile to base) and downlink (base to mobile) messages are communicated. Typically, &mgr;-cell size and location are chosen such that d/r>10. With respect to uplink communications, the transmit powers of the &mgr;-users in a &mgr;-cell are controlled so that the total received power at the nearest M-base is equivalent to the received power from C M-users, where C is usually set to unity. As a result, the M-cell basically loses C users worth of capacity, but the total number of users is increased by virtue of the additional &mgr;-users. With respect to downlink communications, as long as the microbase and the macrobase are coordinated systems, the &mgr;-base transmit power is controlled so that at the point of handoff between a &mgr;-base and M-base, the received power at a user from the two bases is equivalent, and the received power at the bases from this user is also equivalent. With this arrangement, the &mgr;-base transmit power is increased as r grows and d decreases in order for this balance to occur. Where the M-base and &mgr;-base have no knowledge of each other and handoffs are not allowed between the two base types, a family of I/Q short codes which are quasi-orthogonal to the existing short (pilot) codes are generated, and these codes are used to distinguish between the M-base and &mgr;-base signals.

摘要： Techniques are disclosed for reducing channel information feedback in communication networks. For example, a method comprises the following steps. A set of mobile terminals and a set of base stations designated to participate in a coordinated multipoint transmission protocol in a communication network are identified. One or more unique downlink communication resource blocks are assigned to each designated mobile terminal that is located in a given first sector of a designated base station. As such, each designated mobile terminal in the first sector of the designated base station: (i) performs a channel state estimation process in response to respective signals received from the designated base stations in the one or more unique downlink communication resource blocks assigned to that designated mobile terminal; and (ii) transmits resulting channel state information back to at least one of the designated base stations.

摘要： In the method and system, a transmitter demultiplexes an input data stream into M substreams, where each of the M substreams have a data rate lower than a data rate of the input data stream. The substreams are transmitted as signals from a transmit array of M antennas to be received by a receiver array at a receiver in the system, based on a set of transmission parameters. The transmitter adjusts at least one of the transmission parameters based on a condition experienced by the receiver so as to increase data throughput in the system. The adjustable parameters include the number of antennas to employ, the on/off patterns for the antennas, and eigenmode values for the antennas used in order to determine transmit power. Accordingly, system data throughput may be improved while maintaining transmit power and system bandwidth constant.

摘要： A time-division-multiplexed fixed wireless loop system and methods therefor are disclosed. The system comprises a plurality of cells each having a base station and a plurality of terminals. The base station includes a steerable and adjustable multibeam antenna for communicating with each of the terminals, which have fixed antennas. A cell controller associated with each base station allocates communication time slots so as to minimize mutual interference between base station/terminal links sharing the same time slot. Slot assignment is based on regional, periodically updated interference measurements that are stored in data bases.
