摘要： A method and transmitting device are provided for coordinated multi-point transmission scheduling by a transmitting device over one or more heterogeneous wireless networks that include a set of clusters. Each of the clusters has a set of transmission points for serving a set of user equipment devices. The method includes determining constraints imposed on any of the user equipment devices. The method further includes receiving channel state information feedback from the user equipment devices. The method also includes obtaining user weights and buffer sizes. The method additionally includes iteratively determining a weighted sum of user rates based on the constraints, the channel state information feedback, the user weights, and the buffer sizes. The iteratively determining step determines the weighted sum of user rates based on an initial weighted sum of user rates determined for the user equipment devices without the constraints.

摘要： A computer-implemented method for associating users to transmission points over an uplink (UL) of a heterogeneous network (HetNet) is presented. The computer-implemented method includes communicating, via the processor, with a cluster of transmission points, associating each user to one transmission point within the cluster of transmission points by a two-stage procedure, and performing sub-frame scheduling independently by each transmission point within the cluster of transmission points over a set of users associated with.
