Transmitter-side processing of preambles and reference signals

A method for wireless communication, comprising:

• receiving, by a network node, a message comprising modified symbols that are generated by performing a modification on baseline symbols, wherein the message comprises a random access message, wherein the baseline symbols comprise preamble symbols and demodulation reference signal (DMRS) symbols, wherein the modification comprises multiplying the preamble symbols by first complex number and multiplying the DMRS symbols by a second complex number;
• and
• transmitting, to a wireless device and in response to receiving the random access message, a contention resolution message.

A wireless communications apparatus comprising a processor and a memory, wherein the processor is configured to read code from the memory and implement a method, comprising:

• transmitting, by a wireless device, a message comprising modified symbols that are generated by performing a modification on baseline symbols, wherein the message comprises a random access message, wherein the baseline symbols comprise at least one of preamble symbols or demodulation reference signal (DMRS) symbols, and wherein the modification comprises multiplication by a first complex number or multiplication by a second complex number;
• and
• receiving, from a network node and in response to transmitting the random access message, a contention resolution message.
