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: 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.

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: 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: Facilitating shared demodulation reference signal design for control channels in a wireless communications system is provided herein. A system can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise evaluating a usage parameter of a mobile device for application of channel demodulation reference signal reuse by the mobile device. In response to a first determination that the usage parameter satisfies a condition relative to a threshold usage parameter, the operations can comprise facilitating a first transmission to the mobile device to implement the channel demodulation reference signal reuse by the mobile device. In response to a second determination that the usage parameter does not satisfy the condition relative to the threshold usage parameter, the operations can comprise facilitating a second transmission to the mobile device to implement usage of separate channel demodulation reference signals.

Abstract: The described technology is generally directed towards using a frequency-separated band as a supplementary uplink band for a new radio downlink band that cannot operate as a time division duplex band and otherwise has no paired uplink band. The paired bands are separated in frequency, yet operate in the time division duplex mode. The supplementary uplink for New Radio facilitates coexistence with LTE in the frequency division duplex spectrum.

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.
