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: This disclosure relates to embodiments broadcasting timing misalignment (TΔ or T_ delta or Tdelta) information in a fifth generation (5G) new radio (NR) integrated access and backhaul (IAB) network. Tdelta information associated with an IAB node is determined based on a downlink (DL) transmit (TX) timing associated with the IAB node and an uplink (UL) receive (RX) timing associated with the IAB node. A determination is made whether the Tdelta information is to common to at least one child node associated with the IAB node and at least one child user equipment (UE) associated with the IAB node. A message having the Tdelta information is generated in response to the determination that the Tdelta information is common to at least one child node associated with the IAB node and at least one child UE associated with the IAB node. The message is broadcast to the child nodes associated with the IAB node and the child UEs associated with the IAB node.

Abstract: Apparatuses, methods, and computer-readable media are provided for determination of reference signal received power (RSRP) to estimate cross-link interference. The approach uses a received signal from a second UE and downlink (DL) timing information from a transmission reception point (TRP). The approach generates a corrected timing signal based on the received signal, the DL timing information and a reference sequence, and then extracts a symbol from the received signal and the corrected timing signal. The approach then transforms using a fast Fourier transform (FFT) circuit the symbol, and then cross-correlates with a reference sequence to generate a correlation result from which the RSRP is estimated.

Abstract: Resource allocation is provided for an integrated access and backhaul (IAB) network, such as a distributed unit (DU) of an IAB. Methods and systems for allocating resources include allocating a first cell-specific pattern of downlink-flexible-uplink (DL-F-UL) availability for one or more slots, allocating a second cell-specific pattern of DL-F-UL availability for the one or more slots. The IAB DU can signal one or more of the first and second cell-specific patterns to an other IAB DU. At least one of the first cell-specific pattern and the second cell-specific pattern defines a slot format different from a DL-F-UL format. Slot format configuration (e.g., semi-static or dynamic SFI) are provided to support space division multiplexing/spatial multiplexing (SDM).

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for remote interference management (RIM) in wireless networks, including RIM reference signals (RIM-RS) transmitted to assist victim radio access network (RAN) nodes to identify aggressor RAN nodes due to, for example, atmospheric ducting. The RIM-RS is also flexibly configured. Other embodiments may be described and/or claimed.

Abstract: Systems and methods of handover in an information-centric network are described. The ICN-CF receives an update request from an ICN ICN-AMF indicating handover of a UE from a source NG-RAN to a target NG-RAN. The ICN-CF transmits, to an ICN router, an update request to update a PIT and/or FIB table to enable data communications with the UE after handover. The request includes the UE and target NG-RAN, and if the source and target ICN-PoA are different, the source and target ICN-PoA and the ICN-GW.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for compression and decompression of information centric network (ICN) names and/or ICN common fields at Packet Data Convergence Protocol (PDCP) layer. For example, an electronic device can include processor circuitry and radio front end circuitry coupled to the processor circuitry. The processor circuitry can be configured to receive a first information centric network (ICN) packet including an ICN name or an ICN common field and compress the ICN name or the ICN common field at a Packet Data Convergence Protocol (PDCP) layer. The processor circuitry can be further configured to provide the compressed ICN name or the compressed ICN common field to a lower protocol layer. The radio front end circuitry can be configured to transmit a second ICN packet including the compressed ICN name or the compressed ICN common field.

Abstract: The present disclosure is directed to systems and methods for conveying remote interference management information via a reference signal. For example, an interference management method may include receiving, at a first device, an interference signal from a second device. At the first device, a reference signal is generated, including mitigation information for remote interference management. The first device may transmit the reference signal to the second device. The method may further include receiving, at the first device, a mitigation response signal indicative of a level of mitigation undertaken by the second device based on the mitigation information that the first device transmitted.

Abstract: Some embodiments of this disclosure include apparatuses and methods for providing semi-static integrated access backhaul (IAB) resource configurations in an IAB network. For instance, a central unit (CU) of an IAB donor can provide, to a distributed unit (DU) of an IAB node, F1 application protocol (F1AP) signaling data indicative of a semi-static IAB resource configuration regarding at least one of downlink resources, uplink resources, or flexible resources. The semi-static IAB resource configuration indicates whether the at least one of downlink resources, uplink resources, or flexible resources are hard resources, soft resources, or not available resources. The CU can further provide, to a mobile termination (MT) of the IAB node, radio resource control (RRC) signaling data indicative of the semi-static IAB resource configuration.
