    Abstract: Long-term evolution assisted new radio initial access and mobility for 5G or other next generation networks are provided herein. A method can include transmitting, by a first network device of a wireless network and comprising a processor, a first timing synchronization signal and first acquisition information of the first network device to a mobile device. In response to the transmitting and based on a transmission received from the mobile device, a connection between the mobile device and a radio resource control of the wireless network can be facilitated. In addition, in response to the mobile device determining the location of the second timing synchronization signal based on the data indicative of the location of the second timing synchronization signal, the second network device can transmit, to the mobile device, the second timing synchronization signal and second acquisition information of the second network device.

    Abstract: An early termination system for blind decoding is provided to decrease the computational resources utilized when decoding the physical resources, and decrease the time spent decoding. A blind decoding priority list can be used by the mobile device to preferentially decode specific physical resource elements as it specifies the order of all the candidate physical downlink control channels (PDCCHs). When the physical resource elements are decoded, if there is no more downlink control information in that transmission time interval, the downlink control information can include a termination bit, and the mobile device, upon identifying the termination bit can cease blind decoding of the remainder candidates. In this way, the blind decoding process more quickly identifies the downlink control information, and subsequent blind decoding is halted.

    Abstract: Various embodiments disclosed herein provide for facilitating scheduling of uplink data using demodulation reference signal and scheduled resources. According to an embodiment, a system can comprise configuring a network device with a periodic rate of specified sounding reference signals with a periodicity using radio resource control signaling. The system can further facilitate estimating channel state information associated with a channel via which the network device communicates. The system can further facilitate transmitting an uplink grant with uplink transmission parameters to set up a physical uplink shared channel, wherein the uplink transmission parameters are determined based on the channel state information. The system can further facilitate estimating scheduling parameters based on a first estimation information associated with the physical uplink shared channel.

    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.
