Abstract: A method is provided for partitioning data into packets, where each packet has a type k selected from a set of packet types, and a length Lk, in bytes, of payload data. The method includes steps of: determining an expected successful transmit time Ek, for packets of type k, for each of the set of packet types; choosing an optimum packet type for which the value Ek/Lk is a minimum; and partitioning the payload data into packets of the optimum packet type. The method is enhanced by computing a bit error rate (BER) from the retransmission rate for single packet type and using the BER to compute retransmission rates for packets of the remaining types. The method is further enhanced by computing transition tables in advance and using the transition tables to select an optimum packet type.

Abstract: A method and apparatus are provided for adjusting a communication receiver based on the velocity of a wireless communication device in relation to a base station. The receiver is adjusted by estimating a frequency shift of a communication signal transmitted between the base station and the wireless communication device (WCD) based on the WCD velocity. Using this estimate, adjustments are made to the communication receiver to account for the frequency shift of the communication signal. Adjustments to the receiver can include adjusting frequency and time tracking loops to account for the change in frequency of a signal received by, and from, the WCD as it moves relative to the base station. The receiver may be located in the WCD, or in the network infrastructure, or in both.

Abstract: A process and apparatus for timing occurs in a timing discriminator that is part of a time tracking loop. The timing discrimination that prevents Rake finger merging. The process for timing discrimination discriminator is coupled to an input signal. The process begins by gathering early, ontime, and late samples of the input signal.

The timing discriminator output is generated in response to a predetermined relationship between the Early, Ontime, and Late parameters. The process and apparatus enables Rake fingers to freely track their paths. This improves the receiver performance.

Abstract: Accurate calculation of the probability of outage for a cell within a CDMA network is utilized to relate cell coverage to cell capacity. Based on a desired probability of outage, the coverage of the cell may be calculated for an average number of users within the cell. The calculation is independent of the admission policy employed to achieve the specified average number of users. The resulting closed form expression for the tradeoff between coverage and carried traffic allows an optimal design of a CDMA network.

Abstract: Provided herein is a computer-implemented method for generating an optimized cellular-network cell-site plan for an area. A plurality of cellular-traffic demand nodes distributed across the area is provided. Each cellular-traffic demand node of the plurality of cellular-traffic demand nodes has an associated weighting characteristics set. The plurality of nodes are consolidated into a plurality of centroids. Each centroid represents a number of nodes that come within a traffic threshold. A potential cell site is positioned on each of the centroids. Each potential cell site has an associated base-transmitter-station parameter characteristics set. The demand node coverage of each potential cell site is determined with respect to a signal strength of the potential cell site. From the plurality of potential cell sites a minimized cell-site subset is selected while maintaining sufficient cellular service coverage of the plurality of demand nodes.

Abstract: In one embodiment, the invention is directed toward frequency tracking techniques using control symbols that include both pilot and non-pilot symbols. For example, both the pilot and non-pilot symbols can be used in estimating frequency error of a received signal. The contribution of non-pilot symbols to the estimation can be weighted according to a confidence level associated with each non-pilot symbol. In some cases, soft decisions are generated for the non-pilot symbols and then used with the pilot symbols for frequency tracking. In this manner, the frequency tracking loop can be improved.
