    Abstract: Disclosed herein are systems and methods for providing low-latency uplink scheduling requests. For instance, a user equipment (UE) can determine a time of transmission of uplink (UL) data by the UE to a UL device. The UE can further generate control data comprising the determined time of transmission and size information for the UL data. The UE can further provide the control data to the UL device prior to providing the UL data to the UL device. The UE can further receive a UL grant from the UL device. The UE can further provide the UL data to the UL device in response to receiving the UL grant.

    Abstract: An approach is described for a user equipment (UE) to provide contention-based beam failure operation in a second cell (SCell), where the UE includes processor circuitry and radio front end circuitry. The processor circuitry is configured to encode a first message including a beam failure recovery request (BFRQ), wherein the BFRQ is indicative of a beam failure, and to decode a second message from a gNB, wherein the second message includes a beam failure recovery (BFR) response responsive to the BFRQ. The processor circuitry is further configured to encode a third message including a UE identification (ID) in response to decoding the second message, and to decode a fourth message from the gNB, wherein the fourth message includes collision handling for beam failure recovery by the UE. The radio front end circuitry is coupled to the processor circuitry, and the radio front end circuitry is configured to transmit the first message and the third message to the gNB, and to receive the second message and the fourth message from the gNB.

    Abstract: Embodiments of an integrated access and backhaul (IAB) node, a User Equipment (UE), and methods of communication are generally described herein. An IAB node may operate as a relay between an IAB donor and a UE. The IAB node may receive, from the IAB donor, first signaling that indicates a first timing advance (TA) offset between the IAB donor and the IAB node. The IAB node may determine a second TA offset between the IAB node and the UE. The second TA offset may be based on a timing difference between a transmission time of a downlink frame transmitted to the UE and a reception time of an uplink frame from the UE. The IAB node may transmit, to the UE, second signaling that indicates the first TA offset and the second TA offset.

    Abstract: Disclosed are methods, systems, apparatus, and computer programs for determining availability of soft time-domain resources 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 the IAB donor; determining, based on the RRC message, whether soft time-domain resources are available for the IAB node; and in response to determining that soft time-domain resources are available, scheduling a transmission with a child node using the available soft time-domain resources.
