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 technologies described herein are generally directed toward facilitating indicating frequency and time domain resources in communication systems with multiple transmission points. According to an embodiment, a system can comprise a processor and a memory that can store executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include determining a first and a second transmission resource to use for transmission of a signal to a user device by, respectively, a first and a second network node. The operations can further include determining that the first and the second transmission resource comprise a same transmission resource. The operations can further include communicating, to a user equipment, a value corresponding to the first transmission resource and an indication that the first and the second transmission resource comprise the same transmission resource.

Abstract: According to an embodiment, a system can comprise a processor and a memory that can store executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include generating a reference signal in an initial domain, and first transforming the reference signal into a time-frequency domain, resulting in a first transformed reference signal. The operations can further include transmitting the first transformed reference signal to a user equipment for a second transformation to be applied to the transformed reference signal by the user equipment, resulting in a second transformed reference signal. Further, in response to the transmitting the first transformed reference signal, receiving a signal from the user equipment that was configured, based on the second transformed reference signal.

Abstract: Discontinuous access to unlicensed spectrum is facilitated in a new radio access environment. According to an embodiment, a system can comprise performing a scanning procedure that determines whether a first subband and a second subband is available for transmission. The system can further facilitate determining whether the first subband and the second subband are adjacent, wherein a first channel formed at the first subband comprising a first guard band and a second channel formed at the second subband comprising a second guard band that is adjacent to the first guard band. The system can further facilitate in response to determining that the first subband and the second subband are adjacent and available for transmission, eliminating the first guard band and the second guard band.

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: A closed loop carrier sense multiple access multiuser request to send and clear to send handshaking system is provided to efficiently allocate licensed and unlicensed spectrum for a plurality of mobile devices and across different base stations and mobile network operators. A user equipment device can be connected to a base station device via a first frequency in licensed spectrum, and a second frequency in unlicensed spectrum. The air interface on the first frequency can then be used to coordinate physical and virtual carrier sensing on a second frequency among a plurality of user equipment devices. Moreover, carrier sensing results from a plurality of UEs can be reported a base station device via the first frequency in licensed spectrum. The base station device can then schedule multiple user multiple input, multiple output (MU-MIMO) transmissions to a plurality of UEs on the second frequency in unlicensed spectrum.
