    Abstract: PROBLEM TO BE SOLVED: To provide a novel and improved method describing combining of signals in a high-rate wireless communication system. SOLUTION: Reverse link busy bits are independently generated by each base station and indicative of whether the transmitting base station has reached a reverse link capacity limit. A remote station combines multipath components of the reverse link busy bits from each of the transmitting base stations in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations in the remote stations Active Set have reverse link capacity. The remote station weights the reverse link busy signals in accordance with a signal strength of the base station transmitting the busy signal and determines whether to transmit based on the weighted sum of the busy signals.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for tracking signals in a wireless communication system.
    SOLUTION: In one embodiment, a base station includes a rake antenna having a plurality of fingers. When any of the fingers is unlocked, the base station waits a predetermined time period and then adjusts a lock detecting filter 30. The adjustment is performed based on comparison of received signal energy to an adjusted energy threshold 38. The comparison may result in an increased energy level of the filter. In one embodiment, if a mobile station is in soft hand-off mode, the base station ignores the lock state of the fingers and transmits power control information based on the received signal energy. If the mobile station is not in soft hand-off mode, a predetermined power control pattern is applied for gradual power adjustment.

    Abstract: PROBLEM TO BE SOLVED: To provide a distributed infrastructure for wireless data communications. SOLUTION: A mobile user terminal 402 accesses a packet data network 450 through one or more points of a plurality of network access points (404-412). One or more control points (432-440) determine which access point or multiple points the user terminal is to access. Control may be retained in the current control point, or transferred to another control point, whenever it is convenient. There are a plurality of routers, each having an associated home agent (418-420) which determines which foreign agents need to be accessed on behalf of each user terminal. The foreign agents (422-430) forward packets received from a user terminal's home agent to the control point currently controlling communications with the user terminal. COPYRIGHT: (C)2010,JPO&INPIT
