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.

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 5 Generation NodeB (gNB) and an ICN point of attachment (ICNPoA). 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: Embodiments of a system and method for personal area network (PAN) communication for wearable devices in a wireless network are generally described herein. In some embodiments, a wearable user equipment (wUE) includes processing circuitry and transceiver circuitry. The processing circuitry is to: configure the wUE to enter into an active state; and configure the transceiver circuitry to: scan, in response to entering into the active state, for a Beacon signal from a network user equipment (nUE); upon failing to detect the Beacon signal, send a probe signal to the nUE; and upon detecting the Beacon signal or upon receiving a response to the probe signal, connect to a PAN associated with the nUE.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE receive training signals from a plurality of transmit-receive points (TRPs) associated with the gNB. Each training signal may comprise a reference signal resource identifier (ID) to indicate a corresponding TRP and a corresponding transmit direction of a plurality of transmit directions. The UE may, for each transmit direction of the plurality of transmit directions, determine an average signal quality measurement based on individual signal quality measurements in multiple receive directions. The UE may select, for reporting to the gNB, a subset of the average signal quality measurements to ensure that the average signal quality measurements excluded from the subset are less than or equal to a minimum value of the average signal quality measurements in the subset.

The gNB may be configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU 106 may determine a first precoding matrix and a second precoding matrix for a precoding of one or more data streams for transmission on a plurality of antennas coupled to the gNB-DU. The precoding may be in accordance with a split functionality between the gNB-CU and the gNB-DU that includes: precoding by the gNB-CU with the first precoding matrix, and precoding by the gNB-DU with the second precoding matrix.
