Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), small-cell access point (AP), and methods for dynamic millimeter wave pencil cell communication are generally described herein. The UE may receive access point reference signals (APRS) from one or more small-cell access points (AP), and may transmit APRS signal quality measurements to a macro-cell Evolved Node-B (eNB). The UE may receive, from the macro-cell eNB, a message that indicates candidate pencil cells for which the UE is to determine signal quality measurements, the candidate pencil cells supported by the small-cell APs. The UE may receive beam reference signals (BRS) for the candidate pencil cells and may refrain from reception of BRS for pencil cells not included in the message. In some cases, beam-widths of the APRSs may be larger than beam-widths of the BRSs.

Abstract: Disclosed are methods, systems, apparatus, and computer programs for communicating new link availability configurations for a node in an integrated access and backhaul (IAB) network. In one aspect, a method includes receiving a Radio Resource Control (RRC) message from an IAB node; determining, based on the RRC message, a new resource availability configuration for a backhaul resource associated with the IAB node; and in response to determining the new resource availability configuration, conditionally communicating with the IAB node over the backhaul resource according to the new resource availability configuration.

Abstract: A radio access node comprises one or more processors configured to determine a first reference timing of a first communication connection between the radio access node and a second, parent radio access node; determine a second reference timing of a second communication connection between the radio access node and a third, child radio access node; a memory storing the first and second reference timings; the one or more processors further configured to generate a request for the child radio access node to perform a timing advance adjustment based on the stored first and second reference timings, so that an uplink receive signal transmitted by the child radio access node arrives at the same time at the radio access node as a downlink receive signal transmitted by the parent radio access node arrives at the radio access node in case of frequency division multiplexed signals.
