Listen-before-talk (lbt) with new radio-spectrum sharing (nr-ss) discovery signal transmission

An apparatus comprising:

• a processor configured to sense a channel in a spatial domain based on a plurality of expected beam transmission directions, wherein the apparatus is associated with a first network operating entity, and wherein the channel is shared by a plurality of network operating entities including the first network operating entity;
• and
• a transceiver configured to transmit a plurality of discovery signals in one or more of the plurality of expected beam transmission directions during a discovery period to facilitate synchronization in the channel based on the sensing.

A computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a wireless communication device to sense a channel in a spatial domain based on a plurality of expected beam transmission directions, wherein the wireless communication device is associated with a first network operating entity, and wherein the channel is shared by a plurality of network operating entities including the first network operating entity;
• and
• code for causing the wireless communication device to transmit a plurality of discovery signals in one or more of the plurality of expected beam transmission directions during a discovery period to facilitate synchronization in the channel based on the sensing.
