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.

Abstract: This document discusses, among other things, a wireless personal-area network (PAN) underlying a cellular wide-area network (WAN). The PAN includes a wearable user equipment (UE-W) and a user equipment aggregation node (UE-AN). The UE-W includes processing circuitry to process data for communication with a network of the WAN through the UE-AN, and radio interface circuitry to communicate with the UE-AN through a first air interface. The UE-AN includes processing to process data for communication between the network of the WAN and the UE-W, and radio interface circuitry to communicate with the network of the WAN through the first air interface and with the UE-W through a second air interface. The UE-W and the UE-AN can share a network credential, appearing as a single device to the WAN.

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: 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.
