    摘要: A device for modulating communication signals comprises a transceiver for receiving and transmitting the signal, a storage medium storing computer implemented programme code components to generate sequences and a processor in communication with the storage medium and transceiver. The processor executes computer implemented programme code components to generate a family of shift sequences or arrays using exponential, logarithmic or index functions and a polynomial or a rational function polynomial in iεp−1 for a finite field p of prime p. Multiple columns of the arrays are substituted with pseudo-noise sequences or other suitable good correlation sequences in a cyclic shift equal to the shift sequence for the respective column to generate a substituted array. The substituted array, or a sequence unfolded using the CRT from the array when the array dimensions are relatively prime, is applied to a carrier wave of the communication signal to generate a modulated communication signal.

    摘要: A response signal in each subframe is multiplied by a corresponding one of components forming one of a plurality of first sequences orthogonal to each other. The response signal is also multiplied by a second sequence defined by one of a plurality of cyclic shift indexes and one of a plurality of third sequences orthogonal to each other. Among a plurality of resources, a resource associated with one of at least two first sequences of the plurality of first sequences is different from a resource associated with another one of the at least two first sequences. Each of the plurality of resources is constituted by one of the plurality of cyclic shift indexes and one of the plurality of third sequences.

    摘要: Code generating including generating a non-correlation sequence for RS of a first resource block; spreading spectrums of elements in the non-correlation sequence for RS to be mapped to a first frequency resource of the first resource block, by using a first group of codes; second spreading spectrums of elements in the non-correlation sequence for RS to be mapped to a second frequency resource of the first resource block, by using a second group of Codes; the first and second frequency resources are adjacent frequency resources in frequency resource elements used for RS transmission in the first resource block, and the first and second groups of Codes are mirrors in column to each other; and mapping the spectrum-spread elements to the first and second frequency resources, respectively.

    摘要: Method and apparatus for base stations and subscriber units may allow for soft handoff of a CDMA reverse link utilizing an orthogonal channel structure. Subscriber units may transmit an orthogonally coded signal over a reverse link to the base stations. A given base station provides timing control of the timing offset of the reverse link signal. The timing offset may be an absolute timing offset or a differential timing offset. The absolute timing offset may be signaled using more bits than the differential timing offset. Subscriber units may receive power control commands from one or more base stations.
