摘要： In a wireless communication system, user equipments (UEs) may be partitioned into different groups, e.g. based on spatial separation. UEs may use multiple access (MA) signatures that have low or no correlation to each other if the UEs are in the same group. The MA signatures used by one group of UEs may be more correlated with the MA signatures used by another group of UEs. If the UEs are partitioned into the different groups based on spatial separation, then the spatial separation between the different groups may assist in increasing the reliability of detection if two UEs in different groups use correlated MA signatures.

摘要： 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.

摘要： A method of resource allocation for use in a wireless network is disclosed. A network coloring decision to assign a plurality of resource blocks to a plurality of cells within the wireless network is triggered upon occurrence of a network event. A network coloring is performed by assigning each cell of the plurality of cells a resource block from the plurality of resource blocks. An effect of interference among adjacent cells with a same resource block assignment is reduced as measured by a network performance metric related to a number of resource block assignment conflicts over the plurality of cells.
