摘要： Systems and methodologies are described that facilitate dynamic load balancing in a communications network. In particular, one or more mobile devices can send random access preambles on an uplink frequency paired to a downlink frequency employed to connect the one or more mobile devices to a base station. The base station can determine if an uplink frequency load imbalance exists based upon the random access preambles. The base station can transmit an indicator on an acquisition indicator channel to at least one mobile device wherein the indicator includes a command to transition to a new uplink frequency. The mobile device can switch uplink frequencies in response to the command.

摘要： Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. Thermal noise in a sideband may be measured and used as an estimate of thermal noise in a signal band. In one design, samples containing a desired signal centered at DC or a frequency higher than DC may be partitioned into blocks of K samples. Each block of K samples may be transformed with an FFT to obtain a corresponding block of K transform coefficients for K frequency bins. The power of transform coefficients for frequency bins in the sideband may be computed. Thermal noise may be estimated based on power values for the frequency bins in the sideband. Power values for frequency bins in the signal band may also be obtained and used to estimate total received power. RoT may then be estimated based on the estimated thermal noise and the estimated total received power.

摘要： A system for detecting and identifying the identity of a base station or cell which transmits a scrambling code is provided. According to one aspect of the system, the system is used to perform scrambling code detection of eight (8) primary cells (each scrambling code's X-component being spaced sixteen (16) chips apart) in a group. According to another aspect of the system, a single scrambling code generator is used to generate a master scrambling code. The master scrambling code is then used to create individual scrambling codes which are used in correlation with received signals to detect in parallel which one of the eight (8) possible primary cells in the group transmitted the received signals. According to yet another aspect of the system, each of the correlators maintains a corresponding X-component segment of the master scrambling code. For every sixteen (16) chips, a new X-component segment of the master scrambling code is introduced into one of the correlators, a X-component segment of the master scrambling code is dropped from another correlator, and X-component segments of the master scrambling code are sequentially shifted or propagated through the remaining correlators; and concurrent correlations are performed by the correlators using their respective corresponding X-component segments of the master scrambling code and newly received signals.

摘要： Systems and methodologies are described that facilitate increasing throughput in a time-division duplexed CDMA wireless communication environment. A set of orthogonal Walsh code sequences can be assigned to a first group of users in a network sector, and a duplicate set of orthogonal Walsh code sequences can be assigned to at least a second group of users in the sector. A number of receive antennas equal or greater than to the number of duplicate code sets being assigned can be deployed to linearly scale sector capacity to meet user demand. Additionally, user devices employing duplicate Walsh code sequence assignments at a base station serving the sector can be distinguished from each other, and timing offsets between such users can be enforced to mitigate any jamming effect at the base station receiver. Still furthermore, user device channel requirements in the sector can be continuously evaluated and an appropriate number of antennas can be dynamically deployed to provide scalable service to all such user devices.

摘要： The present invention concerns data flow control in adaptive integrated circuitry which utilizes a data flow model for data processing. The present invention controls task initiation and execution based upon data consumption measured in data buffer units. In the various embodiments, when a first task of a plurality of tasks is initiated, buffer parameter is determined and a buffer count is initialized for the first task. For each iteration of the first task using a data buffer unit of input data, the buffer count is correspondingly adjusted, such as incremented or decremented. When the buffer count meets the buffer parameter requirements, the state of the first task is changed, which may including stopping the first task, and a next action is determined, such as initiating a second task. The various apparatus embodiments include a hardware task manager, a node sequencer, a programmable node, and use of a monitoring task within an adaptive execution unit.
