Abstract: The disclosure provides mechanisms for transmission of multiple DCIs. An apparatus for an AN includes RF interface circuitry; and processing circuitry coupled with the interface circuitry and configured to: multiplex one or more PDCCHs carrying DCI for a UE in a TDM manner; perform a resource mapping to map the multiplexed one or more PDCCHs into frequency and time resources in a CORESET; and provide the multiplexed one or more PDCCHs to the RF interface circuitry for transmission to the UE with the frequency and time resources in the CORESET.

Abstract: An apparatus and system of providing a listen before talk (LBT) procedure in multi-carrier or multi-beam mode above a 52.6 GHz band are described. The LBT procedure is performed independently for each carrier or beam to maintain and update a different back-off counter for each carrier or beam. To align a transmission starting time across the carriers or beams, for each carrier or beam: the counter continues to decrement if the counter has reached zero before the starting time and transmit at the starting time if the channel continues to be sensed idle for an additional observation period immediately prior to the starting time and otherwise considers the LBT procedure to have failed. The counter is reinitialized for carriers or beams for which a channel occupancy time (COT) is to be acquired and transmission ceases.
