Abstract: An approach is described of an access node that is configured to exchange intended Uplink (UL)/Downlink (DL) direction information for cross-link interference (CLI) management in a wireless communication system. The access node includes processor circuitry and communication circuitry. The processor circuitry is configured to generate a message including the intended UL/DL DL direction information. The communication circuitry is coupled to the processor circuitry, and configured to transmit the message to a second access node to thereby implement CLI management.

Abstract: Embodiments of a network User Equipment (nUE), wearable User Equipment (wUE), and methods for sidelink communication are generally described herein. 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). When the control channel allocates the subframe as a downlink subframe, the nUE may contend for access to channel resources. 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.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.

Abstract: Disclosed herein are system, method, and computer program product embodiments verifying legitimate victim-aggressor pairs in remote interference management operation. In an embodiment, a first even report is generated by a victim base station based detection of an atmospheric duct and it transmits a victim reference signal with the first event report. The first event report includes an ID of the victim base station. An aggressor base station is triggered to begin monitoring for transmission of the victim reference signal. The aggressor base station sends a second event report if it detects the victim reference signal. The central entity tries to verify that the victim and aggressor are legitimate. If the verification passes, then the central entity sends a message to the aggressor to start of remote interference mitigation. If verification fails, the remote interference mitigation is not triggered and the victim reference signal is ignored.

Abstract: Some embodiments of this disclosure include apparatuses and methods for measuring and/or reporting UE-to-UE crosslink interference (CLI). In some embodiments, a communication network may use transmission reception points (TRPs) to facilitate communications for user equipment (UE). A first TRP may command a first UE to transmit a crosslink interference reference signal (CLI-RS) according to a particular time behavior. A second TRP may command a second UE to measure UE-to-UE CLI using the CLI-RS and the time behavior. The second UE may then report the measured CLI indicating a level of interference caused by the first UE.

Abstract: In a wireless communication environment, there may arise a timing misalignment for SRS-RSRP measurement. In order to address this issue, a UE may receive an uplink transmission from second UE containing the uplink transmission timing for the first UE. The UE may then set its measurement timing to be the same as the uplink transmission timing. The UE then carries out SRS-RSRP measurement according to the newly-set measurement timing.

Abstract: Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel.

Abstract: A device of a New Radio (NR) evolved Node B (gNodeB), a method and a machine readable medium to implement the method. The method includes: processing a first signal sent by a NR evolved NodeB (gNodeB) regarding a primary physical random access channel (PRACH) configuration to be used to encode for transmission a first communication to the gNodeB; processing a second signal sent by the gNodeB regarding a secondary PRACH configuration different from the primary PRACH configuration and to be used to encode for transmission a second communication to the gNodeB; determining the primary PRACH configuration from the first signal and the secondary PRACH from the second signal; and switching from the primary PRACH configuration to the secondary PRACH configuration and encode for transmission the second communication to the gNodeB based on the secondary PRACH configuration.
