Abstract: Aspects of the disclosure relate to devices and methods for managing carrier aggregation. Downlink control information (DCI), transmitted via a primary cell (PCell), may include one or more secondary cell (SCell) dormancy indication (SDI) value(s) for one or more secondary cells (SCells). That DCI may also schedule a physical downlink shared channel. A scheduled entity may transmit acknowledgment information indicating whether the scheduled entity successfully received the DCI. Where the SDI indicates a switch in behavior relative to one or more SCell(s) and the acknowledgment information indicates that the scheduled entity successfully received that DCI, the one or more SCell(s) transition from dormant to active or vice-versa. Accordingly, the scheduled entity conforms its behavior to provide the appropriate dormancy and non-dormancy behavior when utilizing, in addition to the PCell, one or more SCell(s) for wireless communication in carrier aggregation.

The communications involve using two different beacon signals on two different communication channels. Peer beacons are sent using directional millimeter-wave (mmW) communications to provide time synchronization and resource management information to maintain existing links among one or more neighboring peer stations. A separate network discovery beacon is sent over a sub-6 GHz communication channel, to provide mesh network profile information that identifies the mesh network to aid network discovery for wireless communication stations wanting to join the mesh network.
