Methods and apparatus for descrambling received uplink transmissions

A method for facilitating network communication, comprising:

• receiving resource elements (“REs”) of a first symbol from a soft demapper;
• retrieving at least a portion of output bits from at least one shift register;
• descrambling the REs of the first symbol to generate descrambled REs of the first symbol in accordance with the portion of output bits and configuration parameters;
• storing the descrambled REs of the first symbol in an internal memory;
• and
• storing state of the at least one shifter register in an external memory for next descrambling of REs of a second symbol.

An apparatus for facilitating wireless network communication, comprising:

• means for receiving resource elements (“REs”) of a first symbol from a soft demapper;
• means for retrieving at least a portion of output bits from at least one shift register;
• means for descrambling the REs of the first symbol to generate descrambled REs of the first symbol in accordance with the portion of output bits and configuration parameters;
• means for storing the descrambled REs of the first symbol in an internal memory;
• and
• means for storing state of the at least one shifter register in an external memory for next descrambling of REs of a second symbol.

A network processing device for facilitating network communication, comprising:

• an internal memory able to store processed resource elements (“REs”) of at least one symbol;
• a set of linear feedback shift registers (“LFSRs”) coupled to the internal memory and operable to store information relating to a descrambling sequence;
• and
• a descrambling processor, coupled to the set of LFSRs, configured to receiving soft-demapped symbols and configuration parameters, the descrambling processor operable to descramble the REs with a sequence of symbol by symbol in response to descrambling bits generated by at least one LFSR and configuration parameters, the descrambling processor configured to store descrambled REs in the internal memory and store a state of a state of the at least one LFSR in an external memory.
