CPC H04W 72/542 (2023.01) [H04W 16/32 (2013.01); H04W 24/10 (2013.01)] | 20 Claims |
1. An access node comprising:
a wireless communication interface including an antenna structure through which to provide wireless service on a plurality of carriers;
a backhaul communication interface through which to communicate on a core network; and
a controller configured to control service of a user equipment (UE) when the UE is served by the access node with uplink carrier-aggregation over a connection encompassing multiple uplink channels including a primary uplink channel (uplink PCell) and a secondary uplink channel (uplink SCell),
wherein the controller is configured to dynamically set a channel-quality threshold applicable to control when to deconfigure the uplink SCell from service of the UE, wherein dynamically setting the channel-quality threshold comprises adjusting the channel-quality threshold based on uplink spectral efficiency of the access node, and
wherein the controller is further configured to apply the dynamically set channel-quality threshold to control when to deconfigure the uplink SCell from service of the UE,
wherein the dynamically set channel-quality threshold is a downlink channel quality value, and wherein applying the dynamically set channel-quality threshold to control when to deconfigure the uplink SCell from service of the UE includes (i) receiving from the UE, through the wireless communication interface, a report of downlink channel quality, (ii) making a determination of whether the reported downlink channel quality is at least as low as the dynamically set channel-quality threshold, and (iii) responsive to the determination being affirmative, deconfiguring the uplink SCell from service of the UE.
