Abstract: An example method may include a processing system of a channel sounding receiver having a processor receiving from a base station, at a location, a channel sounding waveform via a plurality of carriers, sampling the channel sounding waveform via the plurality of carriers to generate a plurality of per-carrier time domain sample sets, and processing the plurality of per-carrier time domain sample sets via a plurality of discrete Fourier transform modules to provide a plurality of per-carrier frequency domain sample sets. The method may further include the processing system aligning the plurality of per-carrier frequency domain sample sets in gain and phase to provide a combined frequency domain sample set and measuring a channel property at the location based upon the combined frequency domain sample set.

Abstract: An example method may include a processing system of a base station having a processor assigning at least one resource block of a physical downlink shared channel for a transmission of a channel sounding waveform and transmitting the channel sounding waveform via the at least one resource block. Another example method may include a processing system of a channel sounding receiver receiving from a base station, at a location, a channel sounding waveform via at least one resource block of a physical downlink shared channel, and measuring a channel property at the location based upon the channel sounding waveform that is received.

Abstract: A radio resource measurement (RRM) and timing configuration (TC) framework can facilitate efficient configuration of RRM measurements in wireless communications systems with variable carrier and transmission bandwidths. The RMTC can comprise a list of synchronization signal (SS) block measurement and timing configurations (SMTCs) and a list of channel state information reference signal (CSI-RS) measurement and timing configurations (CMTCs). A framework is proposed to allow for efficient signaling of measurement configurations in cellular wireless communications systems with overlapping carriers of varying bandwidths comprising carriers without synchronization signals as well as bandwidth parts covering parts of the spectrum of a carrier.

Abstract: The described technology is generally directed towards operating a user equipment node as a scheduler user equipment (e.g., which can be a local manager of other nodes in a group). The scheduler user equipment receives a scheduling request for the scheduling of the resources for transmission of data by a transmitter user equipment, and based on the traffic type requested, schedules the transmitter user equipment and receiver user equipment(s) with scheduling data/allocated radio resources. The transmitter user equipment can directly transmit to the receiver user equipment(s) on the allocated radio resources, e.g., without further involvement of the scheduler user equipment/local manager. For cellular data, the scheduler user equipment can schedule the transmitter user equipment to transmit to the scheduler user equipment as a receiver node.

Abstract: Facilitating a time-division multiplexing pattern-based solution for a dual-subscriber identity module with a single radio in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise obtaining, by a network device comprising a processor, multiple time-division multiplexing patterns applicable to a mobile device. The multiple time-division multiplexing patterns indicate respective repeating patterns of an on state and an off state of a defined identity of the mobile device. The method also can comprise facilitating, by the network device, a transmission, to the mobile device, of information indicative of the multiple time-division multiplexing patterns. In an example, the mobile device can be configured to operate with at least two subscriber identity modules.

Abstract: An integrated access and backhaul network is provided with network nodes that can establish timing synchronization with any other network nodes. In an embodiment, network nodes in a multi-hop integrated access and backhaul network have a hop order of n, wherein n represents a number of hops from a node connected to the core network via a wired connection. In an embodiment, instead of using the network node with a hop order of 0 as the timing synchronization reference for over-the-air synchronization, any network node can use any other network node as a synchronization reference. A relay node can first establish a wireless link to said arbitrary node. Said wireless link is then used to synchronize the relay or IAB node using a Precision Time Protocol (PTP) implementation.

Abstract: One subscriber identity module (SIM) can transmit data in active mode while another SIM is in an idle mode. However, paging for the SIM in idle mode can occur based on a discontinuous reception configuration (DRX) cycle of the active SIM. For example, when the DRX of the active SIM indicates that the active SIM is in an idle state, then the SIM that is currently in an idle state can send messages and vice versa. The DRX cycle information can be exchanged between a first core network and a second core network. Each core network can belong to the same or different mobile network operator and can have separate radio access networks (RAN) or share the RAN. The DRX cycle information and/or a time-division multiplexing (TDM) pattern can be exchanged over the air via a system information broadcast message.
