CPC H04W 74/0816 (2013.01) [H04L 27/2617 (2013.01); H04W 74/002 (2013.01); H04W 84/12 (2013.01)] | 26 Claims |
1. A method for wireless communication performed at a transmitting device, the method comprising:
generating a second scrambler seed value being associated with at least 11 bits, the generation being based on 7 least significant bits (LSBs) associated with a first scrambler seed value, wherein each of the 7 LSBs has a value of zero;
generating a scrambling sequence based on the second scrambler seed value and a polynomial, wherein at least one bit of a portion of the at least 11 bits has a non-zero value, the portion comprising 7 LSBs of the second scrambler seed value;
constructing a physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes a multi-user (MU) request-to-send (RTS) frame and the second scrambler seed value;
scrambling one or more portions of the PPDU based on the scrambling sequence;
transmitting the one or more scrambled portions of the PPDU; and
receiving, after transmitting the one or more scrambled portions, clear-to-send (CTS) frames, via PPDU duplicates, wherein each of the PPDU duplicates carries the CTS frame and is received over a corresponding 20 MHz frequency subband.
