A system and method of communicating sounding reference signals (SRSs) in a cellular time division duplex (TDD) mmWave system. A transmission point (TP) may transmit beamformed reference signals to a user equipment (UE), each of the beamformed reference signals having been transmitted according to a beam direction in a set of beam directions available to the TP. The TP may receive a feedback message from the UE that identifies one of the beamformed reference signals transmitted to the UE. The TP may select, from the set of beam directions available to the TP, a subset of beam directions for SRS reception based on the feedback message received from the UE, and receive uplink SRS signals according to beam directions in the subset of beam directions. The set of beam directions available to the TP includes at least one beam direction that is excluded from the subset of beam directions.

The method includes: receiving indication information transmitted by a base station and used to indicate a PRB bundling size; and transmitting, within at least one PRB bundle, the SRS to the base station, wherein the number of PRBs included in the at least one PRB bundle is equal to the PRB bundling size, and a same precoding is used by PRBs belonging to a same PRB bundle, and the precoding is determined by the UE itself.

A method and an apparatus for uplink transmission in a communication system. An operation method of a terminal includes: receiving, from a base station, first SFI information indicating n flexible symbol(s); receiving, from the base station, second SFI information re-indicating m symbol(s) of the n flexible symbol(s) as uplink (UL) symbol(s); and transmitting an SRS to the base station through the m symbol(s) re-indicated as a UL symbol among the n flexible symbol(s) indicated as a flexible symbol. Therefore, performance of the communication system can be improved.

Methods, systems, and devices for wireless communications (e.g., vehicle to everything systems) are described relating to an adaptive design of demodulation reference signals (DMRS) density based on user equipment (UE) velocity. A UE may send assistance information to a transmitting UE to help identify a DMRS pattern based on the relative speed between the two UEs. Also, the transmitter may determine the adaptive DMRS pattern based on its speed without information of the receiver's speed. The transmitter may indicate the adaptive DMRS pattern in control information to the receiver. A base station may receive assistance information, and the base station may determine the adaptive DMRS pattern to be used by the transmitting UE based on the received assistance information and then indicate the adaptive DMRS pattern to the transmitting UE. A UE may determine an adaptive DMRS pattern to use based on feedback from the receiving UE.
