Uplink symbols for demodulation reference signal on open radio access network

A distributed unit (DU), 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 distributed unit (DU) to:
• receive, from a remote unit (RU), an indication of a skew time parameter associated with the RU providing compensated samples for a plurality of symbols associated with a slot;
• and
• receive, from the RU, a burst of compensated samples for the plurality of symbols in a transmission window that is offset in time from a beginning symbol of the slot according to the skew time parameter, wherein the burst of compensated samples are based on a set of samples associated with a first subset of the plurality of symbols, the set of samples based on a processing delay associated with demodulation reference signals during a portion of the first subset of the plurality of symbols.

A method for wireless communications at a remote unit (RU), comprising:

• transmitting, to a distributed unit (DU), an indication of a skew time parameter associated with providing compensated samples for a plurality of symbols associated with a slot;
• storing a set of samples associated with a first subset of the plurality of symbols associated with the slot, the storing based on a processing delay associated with receiving demodulation reference signals during a portion of the first subset of the plurality of symbols associated with the slot;
• and
• transmitting, to the DU, a burst of compensated samples for the plurality of symbols in a transmission window that is offset in time from a beginning symbol of the slot according to the skew time parameter.
