Abstract
A first group embodiments provide a method performed by a network node (NN) in a wireless network comprising responsive to a DL data intended for a user equipment (UE), transmitting a first short signal burst to the UE over a channel using a directional beam, and based on detecting a first response to the first short signal burst from the UE indicating that the channel is available, transmitting at least a portion of the DL data to the UE over the channel using the directional beam. A second group embodiments provide a method performed by a NN comprising determining availability of a channel between the network node and the UE using a directional beam, based on determining that the channel is available, transmitting a first resource grant for transmission of a UL data by the UE, and receiving the UL data from the UE over the channel using the directional beam.
