1. An apparatus for wireless communication, comprising:
one or more processors;
one or more memories coupled with the one or more processors; and
instructions stored in the one or more memories and operable, when executed by the one or more processors, to cause the apparatus to:
receive a plurality of reference signals, including a reference signal, in a time period via a plurality of antenna elements,
wherein each of the plurality of reference signals is from a different user equipment (UE), each of the plurality of reference signals include an identical transmission comb number, each of the plurality of reference signals include at least one of a different cyclic shift or a different comb offset, and the plurality of reference signals are mapped to inconsecutive subcarriers; and
combine, in an analog domain, the reference signal received via each of the plurality of antenna elements based at least in part on weights associated with the plurality of antenna elements,
wherein at least one weight of the weights changes over the time period, and
wherein the weights are elements of a time domain orthogonal cover code or a discrete Fourier transform (DFT) matrix.
