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.

Abstract: Methods, systems, and devices for wireless communication are described. For example, a user equipment (UE) may receive a paging indication over a physical downlink control channel.

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.
