    Abstract: An example method may include a processing system of a cellular network having a processor receiving, from a mobile endpoint device, a measurement of a performance indicator, a location, and spatial orientation information, the measurement of the performance indicator based upon at least one wireless signal from a base station of the cellular network, and adjusting at least one aspect of the cellular network in response to the measurement of the performance indicator, the location, and the spatial orientation information. Another example method may include a processing system of a mobile endpoint device having a processor receiving a wireless signal from a base station of a cellular network, capturing a measurement of a performance indicator based upon the wireless signal, recording a location and spatial orientation information, and transmitting to the cellular network the measurement of the performance indicator, the location, and the spatial orientation information.

    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 communicating with a core network device of a core network by employing a first wireless connection to a first base station device communicatively coupled to the core network device. The operations can further include establishing a second wireless connection with a user equipment to enable the user equipment to communicate with the core network device. The operations can further include communicating a first control message and a second control message to the user equipment, wherein the first control message comprises first parameters associated with the first wireless connection and the second control message comprises second parameters associated with the second wireless connection.

    Abstract: The disclosed subject matter is directed towards highly reliable Hybrid Automatic Repeat Request (HARQ) retransmission procedures, including to provide different levels of reliability for Sidelink transmissions. A scheduler node schedule a data transmission by a transmitter node, and can receive (and store) the data packet transmission. If the scheduler node receives a negative acknowledgement (NAK) from the receiver node, the scheduler node can allocate resources to the transmitter node to perform a retransmission of the data packet, and/or retransmit a copy of the data packet from the scheduler node to the receiver node. The scheduler node can inform the receiver node that a retransmission is being sent by the transmitter node and the scheduler 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.

    Abstract: Systems and methods for computing channel state information in a 5G wireless communication system in 4G spectrum frequencies is described herein. A method as described herein includes determining, by network equipment comprising a processor, that a cell in which the network equipment operates is configured for coexistence between new radio signals and long term evolution signals based on a starting symbol location for non-user equipment specific control signaling received from the cell relative to a frame boundary; predicting, by the network equipment in response to the determining that the cell is configured for the coexistence, long term evolution resource overhead data associated with the long term evolution signals; and determining, by the network equipment, channel state information reference resources at least in part by removing the long term evolution resource overhead data from channel state information computation data.
