CPC H04W 52/0212 (2013.01) [H04L 5/0051 (2013.01); H04W 72/044 (2013.01)] | 30 Claims |
1. An apparatus for wireless communication at a user equipment (UE), comprising:
a first interface configured to:
obtain, from a base station (BS), a configuration of a modulated reference signal for a first orthogonal frequency division multiplexing (OFDM) symbol of a slot,
the configuration indicating an allocation of:
a first portion of a first cyclic prefix (CP) of the first OFDM symbol for the modulated reference signal in a time domain; and
a first frequency band greater than or equal to a second frequency band of a downlink transmission for the modulated reference signal in a frequency domain;
the first interface or a second interface configured to:
obtain, from the BS, the modulated reference signal in the first OFDM symbol of the slot based at least in part on the configuration;
a processing system configured to:
demodulate the modulated reference signal according to one or more hypotheses; and
the first interface or the second interface configured to:
obtain, from the BS, the downlink transmission in the slot based at least in part on the modulated reference signal.
