METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING UPLINK REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240348481 titled 'METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING UPLINK REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEMS

The abstract of this patent application describes a method for a user equipment (UE) to transmit an uplink reference signal in a wireless communication system. The method involves applying transform precoding and pi/2 binary phase shift keying (BPSK) modulation to a physical uplink shared channel (PUSCH) based on received information, as well as applying pi/2 BPSK modulation to an uplink demodulation reference signal (DMRS) based on additional received information. The method also involves identifying a sequence with characteristics of a first peak-to-average power ratio (PAPR) based on the received information.

  • Key Features and Innovation:
   - Application of transform precoding and pi/2 BPSK modulation to PUSCH.
   - Application of pi/2 BPSK modulation to UL DMRS.
