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 IAB node may transmit, to the UE, second signaling that indicates the first TA offset and the second TA offset.

The nUE may transmit a control channel that allocates a subframe as either a downlink subframe or an uplink subframe for a sidelink communication between the nUE and a wearable User Equipment (wUE).

The contention may include transmission of a transmitter resources acquisition and sounding (TAS) channel in a physical resource block (PRB) and an attempted detection of a receiver resources acquisition and sounding (RAS) channel from the wUE in the PRB. When the control channel allocates the subframe as an uplink subframe, the wUE may contend for access to the channel resources.

An ML training host trains and evaluates ML models in the catalog, obtains training and testing data from the database, and retrains and updates the ML models.

Abstract: To configure an IAB node for multiplexing communications within an IAB network, processing circuitry is to encode configuration signaling for transmission to a CU function of an IAB donor node. The configuration signaling indicates a multiplexing capability of the IAB node. RRC signaling from the CU function of the IAB donor node is decoded. The RRC signaling configures scheduling resources for a parent backhaul link between the MT function of the IAB node and a DU function of a parent IAB node based on the multiplexing capability of the MT and DU functions of the IAB node. Uplink data is encoded for transmission to the parent IAB node by the MT function using to the scheduling resources for the parent backhaul link. Transmission of the uplink data is multiplexed with transmission or reception of data by the DU function of the IAB node based on the multiplexing capability.

Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.
