Abstract: Some embodiments of the present disclosure enable a device to select a spatial domain filter such that a resultant listen-before-talk (LBT) sensing beam, or a subsequent transmit/receive beam, has a specific spatial relationship with a plurality of transmission beams for transmissions that are multiplexed in a space division multiplexed (SDM) manner, multiplexed in a time division multiplexed (TDM) manner or a multiplexed in a combination of both an SDM manner and a TDM manner. The selection of the spatial sensing filter for the LBT sensing beam may be based on the spatial attributes of the transmission beams, including at least one of beamwidth, beam peak direction and beam center direction.

Abstract: Some embodiments of the present disclosure provide for configuring channel access mechanisms in a mmWave shared spectrum mobile communication network. The channel access mechanisms are to be used by a user equipment (UE) and a serving node in the UE's serving cell. The configuring may use a single, cell-specific higher layer parameter or a combination of two cell-specific higher layer parameters. The parameters may configure the UE and the node to perform channel sensing before transmitting to initiate a channel occupancy. Alternatively, the UE and the node may be configured to transmit directly without channel sensing. The parameters may configure a receiver (the UE or the node) to perform channel sensing before transmitting a channel idle indication to the transmitter as part of a channel access procedure to initiate a channel occupancy. Alternatively, the parameters may configure the UE and the node to receive without channel sensing.

Abstract: A user equipment (UE) may transmit a configured-grant uplink control information (CG-UCI) to a base station during a channel occupancy time (COT) initiated by the UE in a shared spectrum, the CG-UCI comprising COT sharing information, the COT sharing information indicating, at least, an index value corresponding to a combination of: an indication of an offset to a beginning of a downlink transmission opportunity during the COT; an indication of a duration of the downlink transmission opportunity during the COT; and an indication of a channel access priority class (CAPC) value used by the UE to initiate the COT. The base station may transmit a downlink transmission to the UE within the downlink transmission opportunity and in accordance with the COT sharing information in the transmitted CG-UCI. Apparatuses are also disclosed.
