Abstract: Methods, systems, and devices for wireless communications are described. The network may manage access to a cell on a per-beam basis. The network may indicate, for a given beam, whether a user equipment (UE) is able to access the cell via the given beam. Accordingly, the UE may access a cell using a beam that is not barred for the UE. In some examples, control signaling may include a list of each beam associated with the cell and may indicate whether each beam is barred or accessible. In some examples, control signaling include a field indicating whether the particular beam on which the control signaling was transmitted is barred. In some examples, control signaling may indicate whether a cell is barred. The UE may interpret the indication of whether the cell is barred as indicating whether the beam on which the control signaling was transmitted is barred.

Abstract: Methods, systems, and devices for wireless communications are described. Idle discontinuous reception (I-DRX) configurations may be managed on a per beam or a per subset of beams basis. The network may indicate, via system information, the I-DRX configuration for a given beam or subset of beams. A user equipment (UE) in an idle mode may receive paging occasions via the given beam in accordance with the indicated I-DRX configuration for that beam. In some examples, system information may indicate a list of beams and corresponding I-DRX configurations for each beam in the list of beams. In some examples, system information may indicate the I-DRX configuration for the beam on which the system information is transmitted. If a UE changes beams, the UE may receive system information via the new beam that indicates an I-DRX configuration for the new beam before applying the I-DRX configuration to the new beam.

The subset of beams may be less than a quantity of beams available to the network entity for transmitting the paging message and a coverage area of the subset of beams may include the position of the UE. The UE may monitor, based on receiving the paging indication, the subset of beams over a physical downlink shared channel for the paging message.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first communication device may receive, from a second communication device, control signaling triggering a channel access procedure at the first communication device. In some case, the channel access procedure may be for accessing the shared radio frequency spectrum. The first communication device may then perform the channel access procedure based on the control signaling. In some examples, the first communication device may, based on the channel access procedure, transmit an indication of a channel occupancy initiated by the first communication device to the second communication device. The first communication device may relay communications between the second communication device and a third communication device during a channel occupancy time (COT) based on the transmitted indication of the channel occupancy initiated by the first communication device.
