Abstract: Technology for an Information Centric Networking gateway (ICN-GW) operable to modify an ICN message received from a user equipment (UE) in a Fifth Generation (5G) cellular network is disclosed. The ICN-GW can decode the ICN message received from the UE via a Next Generation NodeB (gNB) and an ICN point of attachment (ICN-PoA). The ICN-GW can modify the ICN message to produce a modified ICN message. The ICN-GW can encode the modified ICN message to route the modified ICN message to a data network.

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 bandwidth-flexible in order to enable detection of the RIM-RS by aggressor RAN nodes with different bandwidth configurations. Other embodiments may be described and/or claimed.

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.

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.

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: Embodiments of this disclosure include apparatuses and methods for data channel mapping type and demodulation reference signal (DM-RS) configuration to enable a physical layer (L1) crosslink interference (CLI) measurement and reporting. Some embodiments are direct to a method of operating a base station (BS), where the method can include generating, by the BS, a demodulation reference signal (DM-RS), determining, by the BS, a position of the DM-RS in a first transmission slot, transmitting, by the BS, the DM-RS to a UE based on the determined position in the first transmission slot, processing, by the BS, a crosslink interference (CLI) measurement fed back based on the DM-RS, wherein the CLI measurement fed back is in a channel state information (CSI) report, and performing, by the BS, a CLI mitigation based on the CLI measurement.

Abstract: Techniques discussed herein can facilitate reduced frequency of triggering a RLF (Radio Link Failure) timer and/or a false RLF procedure via employing one or more mechanisms for associating BFR (Beam Failure Recovery) and RLF. A first mechanism that can be employed in various embodiments can perform one or more RLF-related actions (e.g., stopping a T310 timer, resetting a N310 counter) upon BFR success. A second mechanism that can be employed in various embodiments can comprise revising one or more RLF parameters (e.g., N310, N311, T310, Out-of-sync threshold, in-sync threshold, etc.) based on the presence of a strong BFR mechanism.

Abstract: In NR networks with dynamic TDD operation, two types of cross-link interference (CLI) arise: UE-to-UE and TRP-to-TRP. UE-to-UE CLI measurement and reporting can assist the network in managing CLI. The problem is that, for a cell to be able to measure the CLI reference signal transmitted by UEs in another neighboring cell, the cell needs to know what CLI-RS transmission resources assigned to the UEs in the neighboring cells. Embodiments of the present disclosure provide systems and methods for the exchange of such information between cells. In some embodiments, for example, a gNB sends a request message to a neighboring gNB and the neighboring gNB sends back a response message that includes TDD DL/UL Configurations of its cells and a list of the resources assigned to its UEs for transmission of UE-to-UE CLI reference signal.

Abstract: An approach is described for a method for a base station in a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes determining base initial seeds and a time parameter. The method further includes generating actual initial seeds based on the base initial seeds and the time parameter; generating a Pseudo-Noise (PN) sequence based on one of the actual initial seeds; and generating a remote interference management reference signal (RIM-RS) sequence based on the PN sequence. The method further includes transmitting the RIM-RS sequence to a remote base station.
