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: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

Abstract: Disclosed herein are systems and methods for providing low-latency uplink scheduling requests. For instance, a user equipment (UE) can determine a time of transmission of uplink (UL) data by the UE to a UL device. The UE can further generate control data comprising the determined time of transmission and size information for the UL data. The UE can further provide the control data to the UL device prior to providing the UL data to the UL device. The UE can further receive a UL grant from the UL device. The UE can further provide the UL data to the UL device in response to receiving the UL grant.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for dynamic indication of soft resource availability. Some embodiments are directed to an apparatus in an Integrated Access and Backhaul (IAB) node. The apparatus includes processor circuitry and radio front circuitry. The radio front end circuitry can be configured to receive, from a second IAB node, a slot format indicator (SFI). The SFI can include a slot format entry including a soft symbol indicating availability of a soft resource. The processor circuitry can be configured to use the slot format entry to communicate with a third IAB node, different from the second IAB node, using the soft resource as indicated by the soft symbol.

Abstract: Embodiments of an integrated access and backhaul (IAB) node, a User Equipment (UE), and methods of communication are generally described herein. An IAB node may operate as a relay between an IAB donor and a UE. The IAB node may receive, from the IAB donor, first signaling that indicates a first timing advance (TA) offset between the IAB donor and the IAB node. The IAB node may determine a second TA offset between the IAB node and the UE. The second TA offset may be based on a timing difference between a transmission time of a downlink frame transmitted to the UE and a reception time of an uplink frame from the UE. The IAB node may transmit, to the UE, second signaling that indicates the first TA offset and the second TA offset.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided 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: Disclosed are methods, systems, apparatus, and computer programs for determining availability of soft time-domain resources for a node in an integrated access and backhaul (IAB) network. In one aspect, a method includes receiving a Radio Resource Control (RRC) message from the IAB donor; determining, based on the RRC message, whether soft time-domain resources are available for the IAB node; and in response to determining that soft time-domain resources are available, scheduling a transmission with a child node using the available soft time-domain resources.

Abstract: Some embodiments of this disclosure include apparatuses and methods for supporting integrated access and backhaul (IAB) networks. IAB nodes may be configured to broadcast in-raster and off-raster synchronization signal blocks (SSBs) for establishing communications with mobile devices and/or user equipment (UE). The SSBs may provide control resource set (CORESET) data used for establishing a communication channel between a UE and an IAB node. The CORESET data may be configured to support the broadcast of off-raster SSBs in wireless communication systems. In some embodiments, the in-raster SSB and the off-raster SSB may share the same CORESET. In this case, the IAB may modify a bit pattern of configuration table corresponding to the shared CORESET and broadcast the in-raster SSB and the off-raster SSB while including the modified bit pattern.
