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.
