Abstract: Various embodiments disclosed herein provide for a power control system in a multi-hop integrated access and backhaul network. In the 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 can manage the power levels of the relay node in order to reduce the difference in power levels. The power control system can schedule relay node devices to transmit uplink transmissions alongside user equipment devices that have a high signal strength; schedule relay nodes and user equipment devices to separate symbols within a time slot; and/or perform closed loop power control management at the relay node to reduce the power level for an uplink transmission.

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: Facilitating sparsity adaptive feedback in the delay doppler domain in advanced networks (e.g., 4G, 5G, 6G, and beyond) is provided herein. Operations of a method can comprise determining, by a first device comprising a processor, a channel covariance matrix in a time-frequency domain based on a channel estimation associated with reference signals received from a second device. The method also can comprise decomposing, by the first device, the channel covariance matrix into a group of component matrices. Further, the method can comprise transforming, by the first device, respective matrices of the group of component matrices into respective covariance matrices in a delay doppler domain. The method also can comprise determining, by the first device, channel state information feedback in the delay doppler domain.

Abstract: Aspects of the technology described herein are directed towards using generic control information in a three-party wireless communication system to schedule a data transmission and reception of the data transmission. A scheduler node transmits the generic control information, comprising identification information that identifies a user equipment device as a transmitter node, and scheduling information that schedules a data transmission. For unicast data transmissions, the generic control information further identifies a receiver node, and can schedule transmission of an ACK/NACK from the receiver node corresponding to receiving the data transmission. A control procedure can be configured in a user equipment device by linking a channel configuration dataset to a resource configuration dataset, which in turn is linked to a channel transmit and receive configuration dataset. Reconfiguration is achieved by changing the linking(s) between one or more different available datasets.

Abstract: The described technology is generally directed towards sharing a radio by multiple subscriber identities at a device. A time division multiplexing pattern at the device radio gives primary radio use to a first subscriber identity, while also providing time windows for radio use to a second subscriber identity. In response to a communication by the second subscriber identity, the time division multiplexing pattern can be changed to give the primary radio use to the second subscriber identity. Also, a radio resource control protocol can designate appropriate states for the different subscriber identities, designating the subscriber identity with primary radio use as connected, while the other subscriber identity is designated as inactive or idle.

Abstract: Time domain resource allocation is facilitated for a physical downlink shared channel. For instance, a physical downlink shared channel associated with a mobile device can be configured via a broadcast channel, and a data structure associated with the physical downlink shared channel corresponding to a physical downlink control channel can also be configured. The configured data structure can be sent to the mobile device to be utilized for physical downlink shared channel transmissions between the wireless network device and the mobile device. Additionally, the time domain resources can be allocated by transmitting a physical downlink shared channel transmission to the mobile device based on a condition associated with a radio resource control connection being determined to not have been satisfied.

Abstract: The described technology is generally directed towards over the air synchronization of network nodes. In general, the techniques disclosed herein can be implemented by a first base station node device and a second base station node device. A wireless backhaul connection between the base station node devices allows the first base station node device to connect to a core network via the second base station node device. The techniques disclosed herein can be implemented as a protocol including communications back and forth between the base station node devices, which enables measurement of communication delays such as propagation delays and processing delays. The base station node devices can then use the measured communication delays to better synchronize clocks used to time radio frequency transmissions.
