Title:
SCRAMBLING OF PHYSICAL CHANNELS AND REFERENCE SIGNALS IN WIRELESS COMMUNICATION NETWORKS
Document Type and Number:
WIPO Patent Application WO/2019/138314
Kind Code:
A1
Abstract:
Radio network nodes, wireless devices, and related methods are provided in which a pseudo-random sequence initialization value, which is used during the generation of pseudo-random and/or scrambling sequences, is based, at least in part, on a first identifier, wherein the first identifier is equal to a first parameter if the first parameter has been configured and if a second identifier corresponds to a wireless-device-specific identifier.
