Abstract: To facilitate signal alignment for an integrated access backhaul (IAB) node, a system can determine a subset of beams that can be used for communication transmissions. Based on a signal quality associated with the subset of beams, the system can indicate that the subset of beams is to be used for the communication transmission. Consequently, the subset of the beams or another subset of the subset of the beams can be utilized for the communication transmission based on the signal quality of the beams.

Abstract: Aspects of the subject disclosure may include, for example, receiving, by a first radio module at a first location, a wireless signal, to obtain a first received RF signal. The wireless signal includes information originating at a remote transmitter and conveyed via a wireless channel. An envelope of the first received RF signal is detected by the first radio module without requiring a local oscillator, to obtain a first baseband signal. The first baseband signal may be filtered and/or amplified, after which it is provided to a processor. The processor also obtains a second digital signal from a second radio module receiving the wireless signal at a second location and determines an estimate of the information originating at the remote transmitter according to the first and second signals. Other embodiments are disclosed.

Abstract: A system facilitating compact signaling design for reserved resource configuration via a multi-dimensional bitmap is provided for a wireless communication system. A method comprises: determining a multi-dimensional bitmap (MDB) in time and frequency domains, wherein the time domain is represented by an orthogonal frequency division multiplexed (OFDM) symbol and the frequency domain is represented by an OFDM subcarrier. The determining comprises: selecting a group of reserved resource allocations of the MDB in which data information is not to be communicated; assigning a first value for the OFDM multiplexed symbol and the OFDM subcarrier according to a location of elements of the group of reserved resource allocations; and assigning, to other portions of the MDB other than the group of reserved resource allocations, a second value distinct from the first value. The method also comprises facilitating, by the device, transmitting the MDB to a mobile device.

Abstract: The described technology is generally directed towards dynamic resource coordination that supports multi-hop based relaying for integrated access and backhaul (IAB) in New Radio (5G). Described is a technology in which an IAB node and a serving parent node use wireless signaling to dynamically adapt downlink and uplink resources used for access and backhaul links. An IAB node receives scheduling data from a parent node, configures a frame structure comprising mobile termination function subframes and distributed unit component subframes, and communicates data based on the frame structure. The parent node explicitly or implicitly indicates that a portion of the scheduling data is adaptable, e.g., sends a dynamic frame structure coordination message. In response, the IAB node can adapt the frame structure into a modified frame structure and can communicate further data based on the modified frame structure.

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: The described technology is generally directed towards multidimensional grid sampling for radio frequency power feedback. A mobile device can sample radio frequency signal power at multiple sample points, and can send sample values to a base station. The multiple sample points can be defined with reference to a grid having a first dimension and a second dimension, such as time and frequency, or delay and Doppler. A variety of techniques are provided to define the multiple sample points.

Abstract: Various embodiments disclosed herein provide for power control system in a multi-hop integrated access and backhaul network. In a multi-hop integrated access and backhaul network a donor node can communicate with user equipment devices and relay nodes that have varying power levels, and to avoid receiving uplink transmissions with varying power levels which can impact automatic gain control systems and lower overall throughput, the power control system disclosed herein can manage the power levels of the relay node in order to reduce the difference in power levels. In one embodiment, the power control system can schedule relay node devices to transmit uplink transmissions alongside UE devices that have a high signal strength. In another embodiment, the power control system can schedule relay nodes and UE devices to separate symbols within a time slot. In another embodiment, the power control system can perform closed loop power control management at the relay node to reduce the power level for the uplink transmission.
