Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives an indication for transmitting a particular DMRS sequence in an uplink transmission. The particular DMRS sequence is time domain based. The UE generates the particular DMRS sequence. The UE modulates the particular DMRS sequence to obtain a set of symbols. The UE maps a plurality of symbols of the set of symbols to a plurality of subcarriers. The UE transmits the plurality of symbols on the plurality of subcarriers.

Abstract: Various solutions for channel information feedback with prior information with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a reference signal transmitted by a network side including at least one network node. The apparatus may obtain at least one selected basis. The apparatus may derive a channel response information observed by a receiving domain of the apparatus according to the reference signal. The apparatus may decompose the channel response information into a preferred domain. The apparatus may determine a simplified linear combination coefficient representation of the channel response information in the preferred domain according to the selected basis. The apparatus May report a compressed channel information to the network side based on the simplified linear combination coefficient representation and the preferred domain.
