Abstract
Various aspects of the present disclosure relate to a UE that receives a resource allocation for wireless communication associated with using at least two antennas of the UE, and the wireless communication includes a respective signal associated with each respective antenna of the two antennas. The UE can multiplex a set of modulation symbols associated with the two antennas based on a cyclic-prefix orthogonal frequency-domain multiplex operation. The UE can then transmit the respective signal associated with each respective antenna of the two antennas based on the multiplexing, where a delay of a first signal associated with a first antenna relative to a second signal associated with a second antenna is based on the resource allocation for the wireless communication.
