  • Publication number: 20210243729
    Abstract: Methods and apparatus for providing a resource element identification system to process received uplink transmissions. In an embodiment, a method is provided that includes receiving soft-demapped symbols that comprises resource elements. The method also includes descrambling the resource elements of the symbols one-by-one using descrambling bits generated by at least one linear feedback shift register (LFSR). After each symbol is descrambled, a state of the at least one LFSR is stored as a stored state. The method also comprises restoring the stored state to the at least one LFSR before a next symbol is descrambled so that generation of the descrambling bits continues from symbol to symbol. The method also comprises forwarding the descrambled symbols to a downstream combining function.

  • Patent number: 9825799
    Abstract: An aspect of present invention discloses a transceiver processing hardware (“TPH”) which is configured to process wireless information based on a constellation map. The TPH includes a minimum mean square error (“MMSE”), an inverse discrete Fourier transform (“IDFT”), and a demapper. The MMSE provides estimation of received bit stream, and the IDFT generates a list of samples associated with frequency of the bit stream. The demapper configured to discard unused constellation points includes a minimum function component (“MFC”) and a special treatment component (“STC”). While MFC is able to receive a bit stream representing a symbol corresponding to a quadrature amplitude modulation (“QAM”), the STC is configured to force one or more infinity values to facilitate generation of an LLR value representing a logic value of the symbol.

  • Patent number: 9509362
    Abstract: A transceiver processing hardware (“TPH”) configured to process wireless bit stream(s) includes a minimum mean square error (“MMSE”), an inverse discrete Fourier transform (“IDFT”), a demapper, a descrambler, and a combiner. While MMSE estimates transmit the bit stream, IDFT generates samples associated with the frequency of the bit stream. The demapper, in one embodiment, is configured to discard one or more unused constellation points relating to the frequency of bit stream from the mapping rules. The demapper, in one aspect, includes one or more minimum function components (“MFCs”) and a special treatment component (“STC”). MFCs are able to receive and compare bit stream(s) representing a symbol which corresponds to a quadrature amplitude modulation (“QAM”). STC, in one aspect, is able to force infinity values to the MFCs when the bit stream or stream of bits is identified as ACK or RI with a predefined encoding category.
