Abstract: PROBLEM TO BE SOLVED: To more efficiently control transmission power for data transmission that uses a number of formats. SOLUTION: Different formats for a given data channel may require different target SNIRs to achieve a particular BLER. Individual target BLER may be specified for each format of each data channel. In a first power control scheme, multiple individual outer loops are maintained for multiple formats. For each format, its associated outer loop attempts to set the target SNIR such that the target BLER specified for that format is achieved. In a second power control scheme, multiple individual outer loops are maintained and the base station further applies different adjustments to the transmission power levels for different formats.

Abstract: PROBLEM TO BE SOLVED: To make noise measurements within a factor of a single symbol period of a longest orthogonal code symbol.
SOLUTION: A control processor 520 identifies an unoccupied code having a spreading factor that is less than a longest spreading factor for the system. A despreader 512 measures symbol energy based on the unoccupied code and a noise estimator 516 generates noise estimations based on the measured symbol energies. A subscriber station uses similar techniques in order to perform channel estimations within a period that is a fraction of a symbol period of a longest-spreading-factor code.

Abstract: In a wireless communication system (10) having a composite transport channel made up of individual transport channels, a method for closed loop power control wherein multiple instances of the outer loop are performed in parallel. The method determines a Signal-to-Interference Ratio (SIR) threshold for the composite channel based on a channel quality metric evaluated for each of the individual channels. In one embodiment the channel quality metric is a Cyclical Redundancy Check (CRC) outcome.

Abstract: Systems and techniques are disclosed relating to wireless communications. These systems and techniques involve wireless communications wherein a device may be configured to recover an information signal from a carrier using a reference signal, detect a frequency error in the information signal; and periodically tune the reference signal to reduce the frequency error. To prevent GPS performance degradation during LO tuning, a tuning indicator signal may be generated and provided to the GPS receiver to disable GPS operation.

Abstract: Techniques to quickly adjust an SIR target toward a final value needed to achieve a specified target BLER for a data transmission. The outer loop may be implemented with multiple modes. The SIR target may be maintained fixed in a hold mode, adjusted in large down steps to speed up convergence in an acquisition mode, and adjusted by a small down step and a large up step for good and erased blocks, respectively, in a tracking mode. Various schemes may be used to adjust the SIR target by larger down steps in the acquisition mode. These schemes may be used even if data is transmitted intermittently, the target BLER is set to a low value, and/or one or multiple transport channels are used for data transmission. The SIR target may be boosted by a particular amount upon transitioning from the acquisition mode to the tracking mode.

Abstract: A buffer structure for storing intermediate results (i.e., APP data) for a Turbo decoder to increase access throughput, the buffer structure is designed to support concurrent access of APP data for two or more bits for each access cycle. This is achieved by partitioning the buffer into a number of banks, with each bank being independently accessible. To avoid access contentions, the banks are assigned to the rows and columns of a 2-dimensional array used for code interleaving such that APP data for consecutive bits are accessed from different banks. To support "linear" addressing, the banks can be arranged into two sets, which are assigned to even-numbered and odd-number columns of the array. To support "interleaved" addressing, the banks can be assigned to groups of rows of the array such that adjacent rows in the interleaved array are assigned to different groups.
