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: Embodiments are provided to enable distributed open-loop multi-user co-operative multi-point (MU-CoMP) scheduling and transmission. In an embodiment, network nodes schedule data transmissions for UEs among multiple transmission tiers that include a first transmission tier having predetermined modulation and coding and a second transmission tier having adaptive modulation and coding. The first transmission tier and the second transmission tier are in respective time-frequency resources that at least partially overlap. The network nodes transmit the scheduled data transmissions in the transmission tiers according to the scheduling for the UEs. A UE receives CoMP transmissions once it is scheduled for transmission by multiple network nodes.

Abstract: A method of simultaneous bidirectional transmissions, the method comprising determining, by a network element, first transmission time slots for downlink and uplink transmissions for a first plurality of user equipment (UEs); assigning a DL transmission to a first shared time slot of the first transmission time slots for a first UE in the first plurality of UEs; and assigning an UL transmission to the first shared time slot for a second UE in the first plurality of UEs, wherein the first and second UEs form a virtual UE to communicate in virtual full duplex in at least the first shared time slot.

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.
