Abstract: Systems, devices and methods for a backscatter measurement based multiple RACH preamble transmissions are disclosed. A WTRU may receive a JCS-RS configuration comprising a minimum RACH preamble retransmission interval. The JCS-RS configuration may comprise a JCS backscatter power fraction (?) of the WTRU transmit power (PTx). The WTRU may transmit a RACH preamble in a RACH occasion corresponding to a preferred SS/PBCH Index using an initial WTRU transmit beam, having an associated first RA-RNTI value. The backscatter power (PBS) may be measured using the WTRU receive beam corresponding to the WTRU transmit beam used for the RACH preamble transmission. On a condition that PBS>?PTx, the WTRU may retransmit the RACH preamble after a retransmission interval, on resources associated with a second RA-RNTI value. The WTRU may be configured for monitoring the PDCCH common search space with the first RA-RNTI and the second RA-RNTI, for respective RAR window intervals.

Abstract: Embodiments include methods, performed by a mobile terminal (MT) of an integrated access backhaul (IAB) node in a radio access network (RAN), for reporting capabilities of cells in the RAN. Such methods include detecting one or more cells in the RAN and determining whether the one or more cells support IAB (e.g., by receiving information broadcast by the respective cells). Such methods also include sending, to a centralized unit (CU, e.g., of abase station) in the RAN, a measurement report including an indication of whether the one or more cells support IAB. Various techniques can be used to indicated IAB support. In some embodiments, the MT can receive a reconfiguration message, from the CU, for a handover to one of the cells that supports IAB. Other embodiments include complementary methods performed by CUs, as well as MTs and CUs configured to perform such methods.

Abstract: A clock signal in a clock distribution network is transmitted using network packets with the clock signal embedded within a bit of the network packets. The clock signal is adjusted to account for propagation delay in transmitting the clock signal throughout a clock distribution network. The propagation delay is computed using a round-trip packet. When a previous clock signal is received, a timer is set to a local clock's estimate of when the next clock signal will occur minus the propagation delay to the downstream device. When this timer expires, the clock signal is sent to the downstream device, which will allow it to arrive at the downstream device at the same time as the next clock signal is received on the local device.

Abstract: The present disclosure provides systems and methods for timestamping events on edge devices. A trusted source measures the latency to the edge device and the edge device's clock offset, and stores the information at the trusted source for later use. The trusted source sends the latency and the device's clock offset to the edge device for later use. The trusted source or the edge device adjusts a timestamp generated at the edge device using an estimated clock offset. The estimated clock offset is determined by extrapolation or interpolation from measured clock offsets.

Abstract: A method for establishing a Protocol Data Unit (PDU) Session(s) is disclosed. In examples disclosed herein, a device (e.g., a wireless device) uses a unique Port Number(s) (e.g., an internal physical or logical Port Number) to search for a matching User Equipment (UE) Route Selection Policies (URSP) rule(s) having a Traffic Descriptor(s) that matches the unique Port Number(s). The device then determines whether there exists a matching PDU Session(s) associated with a Route Selection Descriptor(s) of the matching URSP rule(s). Accordingly, the device can reuse the matching PDU Session(s) in a presence of the matching PDU Session(s) or establish a new PDU Session(s) in an absence of the matching PDU Session(s). By using the unique Port Number(s) as the Traffic Descriptor(s) in the URSP rule(s), it is possible to simplify configuration of the device, especially for redundant traffic handling.
