CPC H04W 76/15 (2018.02) [H04B 7/0452 (2013.01); H04W 92/10 (2013.01)] | 20 Claims |
1. A method for controlling operation in a wireless communication system having a first access node that provides service on a first air interface and a second access node that provides service on a second air interface, wherein the first and second access nodes support cooperatively providing dual-connectivity service in (i) a single-connection-uplink mode, with uplink user-plane communication being carried on just the second air interface and (ii) a split-uplink mode, with the uplink user-plane communication being split between the first air interface and the second air interface, the method comprising:
determining an uplink Multi-User Multiple-Input-Multiple-Output (MU-MIMO) grouping efficiency of the second air interface; and
based on the determined uplink MU-MIMO grouping efficiency of the second air interface, controlling whether to provide the dual-connectivity service in the single-connection-uplink mode or rather in the split-uplink mode,
wherein the uplink MU-MIMO grouping efficiency of the second air interface represents an extent to which the second access node provides uplink MU-MIMO service.
