1. A user equipment (UE), comprising:
one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
transmit, to a network entity, first control signaling comprising a first shifting time offset indication associated with a downlink channel of a cell associated with the network entity;
receive, from the network entity based at least in part on transmitting the first control signaling, second control signaling indicating a projection matrix associated with the downlink channel;
receive data signaling from the network entity on the downlink channel based at least in part on receiving the second control signaling; and
demodulate the data signaling according to a channel estimation associated with the downlink channel that is based at least in part on the projection matrix.
