    Abstract: The disclosed subject matter relates to facilitating uplink communication waveform selection in wireless communication systems, and more particularly Fifth Generation (5G) wireless communication systems. In one or more embodiments, a system is provided comprising a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. These operations can comprise facilitating establishing a wireless communication link between a first device and a second network device of a wireless communication network, and determining a waveform filtering protocol for application by the first device in association with performance of uplink data transmissions from the first device to the second network device.

    Abstract: Various embodiments disclosed herein provide for optimizing identification of a beam in a massive multiple-input multiple output (MIMO) system. The receiver device can select a beam to use for a transmission, and generate channel state information based on a selection of either a single stage beam selection process or a two stage beam selection process. According to an embodiment of the disclosure, the receiver can select which beam selection process to use based on the context of the receiver device. The receiver can select which beam selection process to use based on the long term signal to noise ratio, or the correlation metrics associated with the receiver and transmitter, or based on the path loss between the transmitter and receiver, or based on the location of the receiver relative to the transmitter.

    Abstract: The described technology is generally directed towards having a transmitter in a wireless network generate and map reference signal sequences (e.g., for demodulation or other reference signal usage) so that the reference signal sequences are non-repetitive in a resource block. Avoiding repetition of the reference signal sequences reduces the peak-to-average power ratio in orthogonal frequency-division multiplexing (OFDM) systems. In one aspect, a transmitter device generates different reference signal sequences to avoid repetition of resource signal sequences, and maps the different reference signal sequences to appropriate (different) resource elements of a resource block. In one implementation, the different reference signal sequences can be based on different indexes of antenna ports. In an alternative implementation, the different reference signal sequences can be based on different code division multiplexing groups.

    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 wireless communications systems in which multiple control channel resource sets (CORESETs) are configured into a CORESET group. The CORESET group may be associated with a usage scenario/quality of service requirement, and used by user equipment to decode downlink control information corresponding to that usage scenario. For example, one CORESET group can be used for URLLC traffic, another for eMBB type traffic and another for mMTC traffic. Different CORESET groups may be used to provide different aggregation level sets, different DMRS pattern configurations, different search spaces, different transmission protocols/schemes, different beam management and recovery procedures, different radio link monitoring and radio link failure procedures, and so on. Different CORESET groups may be associated with different transmission points.
