Title:
PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) DEMODULATION REFERENCE SIGNAL (DMRS) BUNDLING
Document Type and Number:
WIPO Patent Application WO/2020/253517
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) bundling. Certain aspects are directed to a method for wireless communication. The method generally includes generating a message configuring transmission of a first demodulation reference signal (DMRS) and a second DMRS of a frame for DMRS bundling, the first DMRS being multiplexed with a control channel of the frame, transmitting the message to a user-equipment (UE), receiving the frame from the UE in accordance with the configuration, and demodulating the control channel of the frame by performing the DMRS bundling of the first DMRS and the second DMRS.
