Abstract
Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.
