    Abstract: Separate forward dedicated and shared control channels are provided in a spread-spectrum communication. The forward dedicated control channel is used to communicate persistent control information and point to the shared control channel when further intermittent control information concerning transmission of data to a mobile station needs to be communicated. The use of a dedicated control channel for only necessary persistent control information, while only pointing to a shared control channel when it is needed, affords more efficient utilization of system resources.

    Abstract: In a hybrid matrix amplifier array (100), a configurable digital transform matrix (116) is initialize with a matrix of transform coefficients. A plurality of digital input signals (M1-M4) are received at inputs of the configurable digital transform matrix (116). The plurality of digital input signals are transformed to produce a plurality of transform digital signals (A1-A4) using the matrix of transform coefficients. The plurality of transform digital signals are converted to a plurality of transformed analoged signals (206) to produce a plurality of transformed analog signals. The transformed analog signals are amplified (104, 208) to produce amplified transformed signals. Finally, the amplified transformed signals are inverse transformed (102, 210) to produce output signals that correspond to a respective digital input signal (M1-M4). Upon sensing a failure in an amplifier array (104,126) a controller (128) recalls matrix transform coefficients from a memory (130) and write and reconfigures the digital transform matrix (116) to minimize the effects of the amplifier failure at the hybrid matrix amplifier outputs (132).

    Abstract: A mobile station (110) selects an initial data rate for communication between base station (107) and mobile station (110). Mobile station (110) communicates the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rate was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

    Abstract: A communication system (100) includes a forward link (106) from a base station (102) to multiple mobile units (104), the forward link having multiple shared channels (SHCH's) (109), multiple shared control channels (SHCCH's) (108), and multiple dedicated pointer control channels (DPTRCH's) (107), and utilizes HARQ error control for error detection and error correction. The mobile unit, when listening to the DPTRCH, uses a SHCCH pointed to by the DPTRCH to demodulate and decode data on the SHCH. Throughput problems may arise when the mobile unit combines and decodes the SHCH data that is intended for a different mobile unit or incorrectly decodes SHCH data that is intended for the mobile unit. In order to improve the data throughput of the system, the system employs a flush test (902, 904, 1004, 1008) and an energy detector test (1100, 1202) to prevent improperly decoded data blocks from corrupting properly decoded data blocks.

    Abstract translation: 通信系统(100)包括从基站(102)到多个移动单元(104)的前向链路(106),具有多个共享信道(SHCH)(109),多个共享控制信道(SHCCH) 108)和多个专用指针控制信道(DPTRCH)(107),并且利用HARQ错误控制进行错误检测和纠错。 移动单元在收听DPTRCH时使用由DPTRCH指向的SHCCH对SHCH上的数据进行解调和解码。 当移动单元组合和解码旨在用于不同移动单元的SHCH数据或不正确地解码旨在用于移动单元的SHCH数据时,可能出现吞吐量问题。 为了提高系统的数据吞吐量,系统采用冲洗测试(902,904,1004,1008)和能量检测器测试(1100,1202),以防止不正确解码的数据块破坏正确解码的数据块。
