Title:
PUCCH DMRS BUNDLING INDICATION FOR PUCCH REPETITIONS
Document Type and Number:
WIPO Patent Application WO/2022/152217
Kind Code:
A1
Abstract:
Aspects are provided that allow a UE to perform DMRS bundling in PUCCH repetitions in response to a configuration from a base station indicating or enabling the UE to perform the DMRS bundling. The UE receives a configuration from a base station indicating to bundle DMRS in repetitions of an uplink control channel transmission. The UE determines a DMRS bundling window based on the configuration. The UE transmits the bundled DMRS in the DMRS bundling window. The base station processes the bundled DMRS. Improved link quality between the UE and base station and signal gains may accordingly result from applying DMRS bundling over multiple repetitions of PUCCH transmissions.
