1. A first transmission-reception point (TRP) for joint transmission or reception between multiple TRPs, the first TRP comprising:
a processor configured to apply one of a timing adjustment or a frequency offset between the TRPs for one or more of signals, channels, or resources; and
a transceiver operatively coupled to the processor and configured to
signal to a second TRP one of the applied timing adjustment or frequency offset value applied by the first TRP or a requested timing adjustment or frequency offset value requested to be applied by the second TRP,
signal to a user equipment (UE) a timing adjustment or frequency offset value to be applied by the UE for transmission or reception of the one or more of the signals, channels, or resources, and
transmit the one or more of the signals, channels, or resources jointly with the second TRP on one or more frequencies,
wherein signaling of timing adjustment values is in units of one of symbol duration, sampling time duration, or seconds, and signaling of frequency adjustment values is in units of one of subcarrier spacing or Hertz (Hz).
