Title:
A METHOD AND AN APPARATUS FOR PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) DISCONTINUOUS TRANSMISSION (DTX) DETERMINATION IN A WIRELESS COMMUNICATIONS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/006832
Kind Code:
A1
Abstract:
Described is a method and apparatus for processing an uplink (UL) signal at a Physical Uplink Control Channel (PUCCH) in a wireless communication system to determine a discontinuous transmission (DTX) state. The method comprises receiving a UL channel signal at a PUCCH receiver apparatus and, after resource element (RE) demapping of said received UL channel signal in said PUCCH receiver apparatus, normalizing a signal power of at least one signal element or resource. The normalized power is compared to a selected, calculated or predetermined threshold and, based on said comparison, a determination is made on whether or not a DTX state has occurred.
