1. A method for implementing a beam determination procedure, the method comprising:
receiving, by a User Equipment (UE) from an Access Node (AN), a universal Transmission Configuration Indication (TCI) state that identifies a plurality of communication beams to be used for downlink communications and uplink communications, the universal TCI state including applicability information;
identifying, by the UE, a first communication beam from among the plurality of communication beams from the universal TCI state that is to be an uplink communication beam and a second communication beam from among the plurality of communication beams from the universal TCI state that is be a downlink communication beam;
identifying, by the UE, one or more control channels, one or more data channels, or one or more signals from the applicability information that are to utilize the first communication beam or the second communication beam; and
configuring, by the UE, the first communication beam or the second communication beam to utilize the one or more control channels, the one or more data channels, or the one or more signals.
