    Abstract: For determining use of receive diversity in a mobile station, a control system (210 or 401) determines a demand level for use of communication resources. A transmitter (300) communicates a message indicating use of receive diversity at a mobile station based on the determined demand level. In another aspect, a receiver (200) receives a channel and determines transmit power level of the channel for being at a lower or upper transmit power level limit. The control system (210 or 401) controls receive diversity by selecting a number of receiver chains (290) based on the determined transmit power level. In another aspect, receiver (200) receives a channel and determines a channel condition of the channel and duration of the channel condition. Control system (210 or 401) controls receive diversity by selecting a number of receiver chains (290) based on the determined channel condition and the duration.

    Abstract: A "time multiplexed" transmission scheme capable of reducing the amount of interference from other cells operated at the same frequency band. Each cell of a system transmits in designated time intervals (e.g., time slots) during which other interfering cells may be prevented from transmitting. By temporarily "blanking" transmissions from interfering cells during the designated time slots, the amount of interference from these cells is reduced. The improved signal quality may support transmission at a desired or higher data rate, which may not be possible without cell blanking. In one variant, transmissions from the cells are staggered over different time slots. A set of one or more cells may be designated to transmit in each of a number of slot phases. The cells transmit in a staggered manner on theses phases to reduce interference. The transmission scheme may be used for a various channel types (e.g., a control channel) and applications.

    Abstract translation: “时分复用”传输方案能够减少在相同频带上工作的其他小区的干扰量。 系统的每个小区以指定的时间间隔（例如，时隙）发送，在该时间间隔期间可以防止其他干扰小区的发射。 通过在指定时隙期间暂时从干扰小区“消隐”传输，减少了来自这些小区的干扰量。 改进的信号质量可以支持以期望的或更高数据速率的传输，这在没有小区消隐的情况下可能是不可能的。 在一个变型中，来自小区的传输在不同的时隙上交错。 可以指定一组一个或多个小区在多个时隙相位中的每一个中进行发送。 小区在这些相位上以交错的方式发送以减少干扰。 传输方案可以用于各种信道类型（例如，控制信道）和应用。

    Abstract: In a communications network, a network user communicates through a remote unit (155) via at least one base station (150). The communications network includes a first mobile switching center (100) for controlling communications through a first set of base stations (102) and a second mobile switching center (112) for controlling communications through a second set of base stations (108). The network also includes a service providing base station (102D) controlled by the first mobile switching center (100) and providing service to a first transition coverage area using a first pseudorandom noise code. The first transition coverage area defines a boundary between a first system (102) controlled by the first mobile switching center (100) and a second system (108) controlled by the second mobile switching center (112). The network further includes a passage providing base station controlled (108D) by the second mobile switching center (112) for providing service to the first transition area using a second pseudorandom noise code offset in time by a first amount from the first pseudorandom noise code. The passage providing base station provides service to a remote unit (155) only if the remote unit (155) is entering the first transition coverage area while exiting the second system or is about to exit the first transition coverage area while entering the second system.

    Abstract: An improved method and system for performing a pilot signal searching operation in anticipation of handoff in mobile station (18) communication between base stations (12, 14). The mobile station (18) maintains a list of Active Set pilot signals transmitted from base stations with which the mobile station is to communicate through, and a list of Neighbor Set pilot signals (N) from base stations within a predetermined proximity of the mobile station (18). The searching operation contemplates comparing pilot signal strength measurements corresponding to each base station entry within the Neighbor Set (N) to a first predetermined level. One or more entries from the Neighbor Set (N) having a base station signal strength measurement greater than the first predetermined level may be placed in the Pre-Candidate Set (PC). The strength of the pilot signals associated with entries in the Pre-Candidate Set (PC) are then further evaluated to determine eligibility within the Candidate Set (C), from which are selected the entries comprising the Active Set.
