Abstract: Methods and apparatuses for an operation for triggering on-demand synchronous signal/physical broadcast channel block (SSB) or a system information block 1 (SIB1) in a wireless communication system. A method of a user equipment (UE) in a wireless communication system includes receiving a first physical downlink shared channel (PDSCH) from a base station (BS) and determining, based on an indication in the first PDSCH, that a set of synchronization signals and physical broadcast channel (SS/PBCH) blocks is activated for transmission from the BS. The method further includes determining a time domain offset with respect to the first PDSCH, determining that the set of SS/PBCH blocks is to be transmitted after the time domain offset and receiving a SS/PBCH block in the set of SS/PBCH blocks.

A method of a user equipment (UE) in a wireless communication system includes receiving, from a base station (BS), a downlink control information (DCI) format and determining a type of channel access procedure based on a field in the DCI format. The type of channel access procedure is one of: a first type of channel access procedure that includes a random time duration for sensing; a second type of channel access procedure that includes a positive and deterministic time duration for sensing; or a third type of channel access procedure that does not include a time duration for sensing.

Abstract: Methods and apparatuses for adapting a channel sensing threshold in a wireless communication system operating with shared spectrum channel access. A method for operating a base station (BS) includes determining whether an antenna configuration for channel sensing is omni-directional or directional and determining a channel sensing threshold. The channel sensing threshold includes two parts: a first part of the channel sensing threshold being common for omni-directional and directional antenna configurations and a second part of the channel sensing threshold depending on the antenna configuration. The method further includes performing a channel sensing procedure based on the antenna configuration and the channel sensing threshold and transmitting downlink (DL) data over a channel based on the channel being sensed as idle in the channel sensing procedure.
