    Abstract: A wireless communication device (200) including a first CRC coder that generates a first block of CRC parity bits on a transport block and associates the first block of CRC parity bits with the transport block, a segmenting entity that segments the transport blocks into multiple code blocks after associating, and a second coder that generates a second block of CRC parity bits on each code block and associates a second block of CRC parity bits with each code block. The first and second blocks of CRC parity bits are based on first and second generator polynomials. In one embodiment, the first and second generator polynomials are different. In another embodiment, the generator polynomials are the same and the transport block is interleaved before segmenting or the code block are interleaved before encoding with the second block of CRC parity bits.

    Abstract: Una entidad de red de comunicación inalámbrica (400) y un método en el mismo en donde los datos son codificados utilizando un código de corrección de error para formar una primera contraseña, por ejemplo, un código de redundancia cíclica, incluyendo la redundancia; una segunda contraseña es generada mediante la codificación de datos adicionales en una porción de la primera contraseña, en donde la porción de la primera contraseña sobre la cual se codifican los datos está dentro de una capacidad de corrección de error de la primera contraseña.

    Abstract: A communication system (300, 1000) supports Hybrid Automatic Repeat Request (H- ARQ), Adaptive Modulation and Coding (AMC), active set handoff, and scheduli ng functions in a distributed fashion by allowing a mobile station (MS) (1014) to signal control information corresponding to an enhanced reverse link transmission to Active Set base transceiver stations (BTSs) (301, 303, 304) and by allowing the BTSs to perform control functions (314, 316, 318) that were supported by an radio network controller (RNC) in the prior art. The communication system allows time and SIR-based H-ARQ flush functions at the BTSs during soft handoff (SHO), provides a control channel structure to support scheduling, H-ARQ, AMC functions for an enhanced reverse link, or uplink, channel (414) in order to maximize throughput, and enables an MS in a SHO region to choose a scheduling assignment corresponding to a best TFRI ou t of multiple assignments it receives from multiple active set BTSs.

    Abstract: Communication rate in a variable rate communication system is determined by calculating metrics based upon symbol energy over a traffic channel frame (200) and selecting an optimum rate based upon the calculated metrics. The metrics are calculated by selectively accumulating symbol energy, using adders (405-408) and accumulators (409-412) in response to the presence of power control groups (201) within the traffic channel frame (200), as determined by power control group selector (400).

    Abstract: A method and apparatus is provided for generating a decision value (809) for use in signal acquisition and channel estimation. In a first embodiment a receiver (850) is provided including at least two spatially diverse antennas (600, 601) which can receive different, e.g. consecutive, segments of the same signal, a signal characteristic (e.g., energy) determination stage (840) for processing the different segments to determine the separate energy values for the segments, and an accumulator (808) for accumulating the energy values so as to form the decision value or statistic (809). Additional embodiments are also provided.
