Abstract: Techniques to test performance of terminals and access points in CDMA data (e.g., cdma2000) systems. A framework of protocols and messages is provided to support systematic performance testing of terminals and to ensure interface compatibility. The framework comprises a Forward Test Application Protocol (FTAP) for testing forward channels and a Reverse Test Application Protocol (RTAP) for testing reverse channels. Techniques are also provided to (1) test different types of channels (e.g., traffic channels as well as auxiliary channels), (2) test bursty data transmissions, (3) support “persistence” testing (i.e., continued testing over connection and disconnection), (4) force the settings of certain auxiliary channels (e.g., so that the error rate of the channels may be determined), and (5) collect, log, and report various statistics that may be used to derive performance metrics such as throughput and packet error rate.

Abstract: Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

Abstract: This disclosure provides a synchronous packet manager containing a data structure for scheduling future synchronous packet transmissions and arbitrating between synchronous and asynchronous packet transmissions. Slots required for transmitting a synchronous packet are reserved by marking the corresponding entries in a synchronous packet reservation table. Rather than writing packets to many different queues, the application software fills in a single reservation table per BTS sector.

Abstract: Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.

Abstract: A network entity includes a processor configured to regulate the data rate of transmissions over a wireless channel from a base station to a subscriber station based on feedback from the subscriber station, the feedback relating to the wireless channel conditions, the processor being further configured to determine a substitute data rate for one or more transmissions over the wireless channel.

Abstract: Micro-tunnels are used to provide multiple data service sessions to the same mobile node in a wireless communications system. Further, the flexibility of the micro-tunnels optimizes the resources of the system. On request for a data service, an encapsulation configuration record is generated. An encapsulation header is created in response to the encapsulation configuration. The encapsulation header includes a packet service identifier and a micro-tunnel identifier.

Abstract: A novel method is disclosed for the allocation of the capacity of a common channel among a number of data producers. In this method, a producer's future allocation grant is based on the extent to which the producer has used a previous allocation grant. The method is applicable to any system wherein the simultaneous use of a common channel by more than one producer may cause a data collision, and an exemplary application to the reverse link of a CDMA telecommunications system is described. Also disclosed are numerous variations and refinements concerning the estimation of remaining channel capacity, the distribution of such capacity among the various producers, and the use of its allocation grant by each producer.

Abstract: In a communication system (1400) for communication of data, a method and apparatus provide for detecting a request for opening a connection for a user (1407) for communication of data, selecting an open connection, releasing the selected open connection, and allocating, to the user (1407), communication resources corresponding to resources released based on releasing the selected open connection. In accordance with an embodiment, the selected open connection is in an idle open state.

Abstract: A method and apparatus for allocating and using a finite resource to transmit wireless information signals to a plurality of subscriber units is disclosed. Individual subscriber units transmit data rate requests to serving base stations. The data rate requests and weight values associated with each subscriber unit are compared in order to select a subscriber unit as the recipient of data transmitted through the finite resource at any given time. To maximize throughput without starving any single subscriber unit, the method includes calculation and comparison of a desirability metric in choosing a subscriber unit from among a subset of the plurality of subscriber units having comparable weight values.

Abstract: Method and apparatus for a generalized scheduler for scheduling transmissions in a communications system. The scheduler is defined by a priority function of the channel condition and fairness criteria. The generalized scheduler is adapted to apply a variety of combinations of channel condition metrics and user fairness metrics. The scheduler distinguishes among classes of users, allowing individual processing per class. In one embodiment, a system controller receives a Delivery Priority Parameter (DPP) for each of a plurality of users, and maps each DPP to a corresponding common Mapped Priority Parameter (MPP). An operating point is determined and a corresponding MPP value for each of the users is applied to schedule transmissions.
