Abstract:
A method and apparatus for handling a difference between a first and second message prior to decoding is disclosed. The signaling scenario illustrated by FlG. 1 and using the codeword properties defined herein, the various embodiments may combine multiple messages under the hypothesis that the value of a message portion corresponding to any subsequent observed transmission is different. Accordingly, a first set of observations (LLR's) (601) may be compared with a second or subsequent set of observations (603), and if the observations are found sufficiently similar, may be further compared in the context of a hypothesized difference (607) in constituent message information words. Once any difference in information words is identified, the second or subsequent set of observations may be combined (611) with the first set of observations after suitable arithmetic processing, and prior to further decoding.
Abstract:
An iterative method (400) and apparatus for a receiver for reducing interference in a desired signal in a GSM communication system uses a finite-impulse-response filter combined with alternate quadrature component output selection for alternate linear equalization are disclosed. The method includes inputting a burst of data of a received waveform including interference (402), training an alternate linear output filter with a midamble of known quadrature phase (404), providing an estimate of the desired signal by operating on the received waveform with the finite-impulse-response filter (406), generating Log likelihood ratio estimates for a plurality of bits in the burst of data (408), selecting bits from the burst of data base upon a predetermined condition (414), and re-training the alternate linear output filter to provide a second improved estimate of the desired signal.

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:
A wireless communication system that communicates (500) frames having first and second sub-frames (510, 520) with time-frequency resource elements. The first sub-frame including first reference symbol information and the second sub-frame including second reference symbol information, and not more than one of the first and second sub-frames including user specific radio resource assignment information. Wireless communication entities receiving the frames process the time-frequency elements of the first sub-frame using the first reference symbol information and processing the time-frequency elements of the second sub-frame using the second reference symbol information.
Abstract:
A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A control field (1103) may be sent with a payload field (1105) wherein the control field (1103) and payload field (1105) are sent using a single Orthogonal Variable Spreading Factor or a single Walsh Code (1101) wherein various modulation and coding schemes may be applied to the control field (1103) and payload field (1105) such that different modulation and coding schemes may be used within the single channel. HARQ is handled by sending a single retransmission if a NACK message is received or no ACK/NACK message is received at all.
