CPC H04L 5/0048 (2013.01) [H04L 5/001 (2013.01); H04L 5/0037 (2013.01); H04L 5/026 (2013.01)] | 28 Claims |
1. A method for wireless communication by a user equipment (UE), comprising:
receiving a first index assigned to the UE of a plurality of different indexes;
monitoring for a parameter that is distinct from the first index, the parameter indicating a single demodulation reference signal scheme of a plurality of available demodulation reference signal schemes for the UE to apply, the plurality of available demodulation reference signal schemes comprising a first demodulation reference signal scheme comprising an intra-symbol time domain orthogonal cover code scheme and a second demodulation reference signal scheme comprising a time domain cyclic shift scheme;
receiving, based at least in part on the monitoring, the parameter indicating for the UE to use the first demodulation reference signal scheme;
generating a transmission based at least in part on a π/2 binary phase shift keying modulation scheme; and
transmitting, based at least in part on the first demodulation reference signal scheme, the transmission comprising a first demodulation reference signal generated using a first intra-symbol time domain orthogonal cover code in a first demodulation reference signal symbol period and a second demodulation reference signal generated using a second intra-symbol time domain orthogonal cover code in a second demodulation reference signal symbol period,
wherein the first intra-symbol time domain orthogonal cover code, of a plurality of intra-symbol time domain orthogonal cover codes, is based at least in part on a symbol index of the first demodulation reference signal symbol period, the first index, and the parameter.
