Abstract: A master user equipment (UE) device may coordinate device-to-device (D2D) communications amongst a plurality of UE devices. For example, a UE device, which has been designated as a master UE device, may coordinate a D2D communication between a first UE device and a second UE device. The master UE device may be a UE device that obtains an indication that it is a master UE device that is to coordinate D2D communications amongst the plurality of UE devices. In some embodiments, the coordinating the D2D communication may be on behalf of a network and/or to facilitate wireless communication between the network and at least one of the plurality of UE devices.

Abstract: Embodiments of the present disclosure provide mechanisms for the following procedures: network signaling for user equipment (UE) measurements; UE measurements; UE feedback; feedback adjustment at network nodes; scheduling; Acknowledgements/Negative Acknowledgements; and network-wide planning. Some or all of these mechanisms can be used in implementing distributed open-loop multi-user co-operative multi-point (MU-CoMP) technology as well as other non-CoMP, one-tier or centralized wireless transmission technologies. The mechanisms are in line with proposed no-cell technology for 5G communication networks.

Abstract: Various devices and methods are disclosed to support clustering optimization in a communication system. For example, multiple nodes of the communication system can be segmented into multiple clustering plans. Each clustering plan can include multiple clusters that do not overlap with one another within that clustering plan. At least one of the clusters of one clustering plan can overlap at least one of the clusters of at least one other clustering plan. Each node could be a non-boundary node in at least one cluster of at least one clustering plan. Multiple nodes of the communication system can alternatively be segmented into clusters having expanding and contracting borders.

Abstract: Systems and methods are provided for transmit signalling to configure a UE with a UE specific root to use in generating a Zhadoff Chu (ZC) sequence for reference signal transmission. With conventional LTE, a cell specific root is used within each cell. There is a need for a more flexible association between roots and UEs that, for example, allows for multiple roots to be associated with a cell. The provided approach may help with maintaining re-use distance as networks become denser. The method provided in this embodiment improves the capabilities of automatic driving and ADAS of electric vehicles. The method can be applied to vehicle networking, such as V2X, LTE-V, V2X, etc.

Abstract: Methods and devices for configurable sequence usage for user equipment (UE) uplink reference signaling are provided. In one provided method, a transmission reception point (TRP) in a wireless communication network receives a first UL reference signal (RS) associated with a first UL RS sequence from a first UE and receives a second UL RS associated with a second UL RS sequence from a second UE, the first and second UL RS sequences being non-orthogonal. In another provided method, A UE determines an UL RS sequence based on a UL RS sequence root, the UL RS sequence root being a UE-specific root and being independent of a cell identifier of a cell serving the UE. The UE sends an UL RS associated with the UL RS sequence, the UL RS sequence being a Zadoff-Chu sequence.
