    Abstract: A code division multiple access (CDMA) communication system (100) has improv ed control by accurately characterizing coverage and loading parameters related to the CDMA communication system (100). To accurately characterize coverage and loading parameters related to the CDMA communication system, parameter meshes corresponding to parameters of the CDMA communication system are generated. The parameter meshes are evaluated, either individually or in combination, to provide comprehensive information regarding the performance of the CDMA communication system. Based on the results of the evaluation, a controller (113) within the CDMA communication system (100) controls the parameters to improve call quality, loading, etc. of the CDMA communication system (100).

    Abstract: A wireless system includes base station transceivers (102-104) to communicate with at least one mobile station (108), the base station transceivers communicate with a network controller (110). The base station controls a header for a packet frame to be communicated between the base station transceiver and the network controller wherein a portion of the header identifies the frame as one containing no data package. The data bits of the header field may contain a predetermined bit pattern for a frame including no data package. Information received by the base station from the mobile station may be dropped, and the header information replaced with the specified bit pattern, if a decoding metric passes a threshold. The information received by the base station from the mobile station may be dropped, and the header information replaced with the specified bit pattern, if a CRC for the frame received from the mobile station fails.

    Abstract: Power control in a spread-spectrum communication system takes place by determining origination power of a traffic channel based on a number of active demodulators and pilot channel signal quality (610). Once origination transmit power is determined and call origination takes place, the transmit power is reduced at a first rate when a time is less than a time for all active demodulators to be established (615), otherwise the transmit power is reduced at a second rate (621). After all active demodulators have been acquired power control takes place by receiving a Power Measurement Report Message (PMRM) or a Pilot Strength Measurement Message (PSMM), determining, a signal quality metric existing at the remote unit based on the PMRM or PSMM, and adjusting transmit power based on the signal quality metric (645).

    Abstract: A method and apparatus for understanding information relating to communication system performance, including the dynamic nature of the system is provided. Elements of the system are represented (102, 110) as various shapes (30, 32, 40) defined by an number of different parameters on a display device (24). The shapes are characterized by a number of defining parameters and these defining parameters have an association with performance characteristics or performance parameters of the system element. As performance parameter data changes with time, e.g., during system operation, the defining parameters are altered such that the shape representing the system element is modified (106, 114). In this manner a large number of system elements and associated performance characteristics and the time varying nature thereof can be readily displayed to aid the system operator.

    Abstract: The present invention provides a method of scheduling asynchronous transmissions for a plurality of subscriber units (12). The method includes receiving (305) information associated with a plurality of subscriber units that have uplink data to transmit, the information including uplink timing offset information associated with each of the subscriber units (12). Two or more subscriber units (12) are then selected (310) from a set of subscriber units having a timing offset differential, that is below a predetermined threshold, where the timing offset differential is the difference between the timing offset of a first subscriber unit and the timing offset of a second subscriber unit further selectively offset by a multiple of the transmission segment size, which minimizes the difference. The transmission segments, which are available for the uplink of data, are then allocated (315) between the selected two or more subscriber units (12), which limits the number of transmission segments that have at least one of an overlap or a gap, and the amount of any overlap or gap, in order to minimize wasted scheduling opportunities.

    Abstract translation: 本发明提供了一种为多个用户单元(12)调度异步传输的方法。 该方法包括接收(305)与具有要发送的上行链路数据的多个用户单元相关联的信息,所述信息包括与每个用户单元(12)相关联的上行链路定时偏移信息。 然后从具有定时偏移差分的一组用户单元(310)中选择(310)低于预定阈值,其中定时偏移差是第一用户单元的定时偏移之间的差 并且第二用户单元的定时偏移进一步选择性地偏移传输段大小的倍数,这使差异最小化。 然后,可用于数据上行链路的传输段在所选择的两个或更多个用户单元(12)之间被分配(315),这限制了具有重叠或间隙中的至少一个的传输段的数量, 以及任何重叠或差距的数量,以尽量减少浪费的调度机会。
