Patent ID: 11064567

Abstract:
Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive configuration information to configure the UE with a plurality of channel state information reference signal (CSI-RS) resource sets. One of the CSI-RS resource sets may be allocated for beam failure detection (BFD). The UE may determine, based on a sub-carrier spacing (SCS) of a bandwidth part (BWP), a frequency density of the CSI-RS resources in the BWP in terms of a number of resource elements (REs) per resource block (RB). The UE may determine, based on the frequency density of the CSI-RS resources, an evaluation period for CSI-RS based BFD, wherein the evaluation period is longer for higher frequency densities and the evaluation period is shorter for lower frequency densities.
