Abstract: A user equipment can send a notification to a network node indicating that the user equipment is entering a battery saving mode of operation. Reduced physical layer procedures can be implemented based on reduced capabilities indicated by the user equipment. Reduced physical layer procedures can also be implemented based on the network node's reconfiguration of parameters to facilitate the activation of the reduced physical layer procedures. The user equipment can also send to the network node recommendations of reduced physical layer procedures.

Abstract: Facilitating configurable hybrid automatic repeat request (HARQ) feedback types for new radio sidelink communication can be performed for a 5G wireless network. Based on whether reception of data was successful or not, a reception node can send acknowledgement (ACK) data or negative acknowledgement (NACK) data to a base station using an uplink control signal. Therefore, the feedback data can be used to manage subsequent resource allocation decisions within the 5G wireless network.

Abstract: The technologies described herein are generally directed toward communicating determined contention levels of resource pools to user equipments enabling the user equipments to select from available resource pools. 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 assigning determined contention levels to respective ones of a group of resource pools. The operations can further include communicating, to a user equipment device, the determined contention levels, enabling the user equipment device to select a resource pool of the group of resource pools based on the determined contention levels.

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: In a 5G network, new radios (NR) can be deployed as a standalone radio access technology or as a non-standalone radio access technology assisted by another radio access technology. Long-term evolution (LTE), which is widely deployed can provide seamless coverage and uninterrupted connectivity, however NRs can provide significantly increased data rates or new services. However, the deployment of NR can be limited to hotspots under the footprint of LTE. Therefore, dual connectivity between LTE and NR can be utilized for non-standalone NR because control plane functions can be sent over LTE while the data plane can be managed on NR, allowing for simplified NR deployments where device support for both LTE and NR is available.

Abstract: An example method may include a processing system of a channel sounding receiver having a processor receiving from a base station, at a location, a channel sounding waveform via a plurality of carriers, sampling the channel sounding waveform via the plurality of carriers to generate a plurality of per-carrier time domain sample sets, and processing the plurality of per-carrier time domain sample sets via a plurality of discrete Fourier transform modules to provide a plurality of per-carrier frequency domain sample sets. The method may further include the processing system aligning the plurality of per-carrier frequency domain sample sets in gain and phase to provide a combined frequency domain sample set and measuring a channel property at the location based upon the combined frequency domain sample set.

Abstract: A cross link interference (CLI) measurement system is disclosed. The cross link interference measurement system can measure both unconstrained CLI that do not require any special constraints on the frame structure, and constrained CLI that does require special constraints on the frame structure (e.g., measurement gaps). The system does this in part by not only measuring reference signal received powers, but also determining load based on a power scaling of a reference signal and based on angle of arrival determinations.
