Abstract
Systems and methods are provided for managing the power of a secondary node in an E-Utran/New Radio Dual Connectivity (ENDC) configured wireless communication network. In response to determining that one or more transmission blocking conditions have been met, a master node communicates an instruction to the secondary node via a data connection cable or an X2 logical interface to not transmit downlink signals, reducing overall power network power consumption and inter-nodal inference when ENDC resources are not required.
Claims20
A system for managing power of a secondary node in a dual connectivity wireless network, the system comprising:
- a first node configured to communicate with a user device;
- a second node configured to communicate with the user device;
- and
- one more processors configured to perform operations comprising:
- determining that one or more user devices are connected to each of the first node and the second node in dual connectivity session;
- determining that a channel resource utilization of the first node does not exceed a predetermined threshold, the channel resource utilization being a ratio of channel utilization to channel capacity during a predetermined period of time;
- in response to said determinations, terminating a connection between each of the one or more user devices and the second node;
- and
- instructing the second node not to transmit a signal for a predetermined period of time.
A method for managing power of a secondary node in a dual connectivity wireless network, the method comprising:
- determining that one or more user devices are connected to each of a first node and a second node in dual connectivity session;
- determining that a channel resource utilization of the first node does not exceed a predetermined threshold, the channel resource utilization being a ratio of channel utilization to channel capacity during a predetermined period of time;
- in response to said determinations, terminating a connection between each of the one or more user devices and the second node;
- and
- instructing the second node not to transmit a signal for a predetermined period of time.
A non-transitory computer storage media storing computer-usable instructions that, when used by one or more processors, cause the one or more processors to:
- determine that one or more transmission blocking conditions has been met, the one or more transmission blocking conditions comprising a determination that a channel resource utilization of a master node does not exceed a predetermined threshold, the channel resource utilization being a ratio of channel utilization to channel capacity during a predetermined period of time;
- and
- instructing the secondary node not to transmit a signal for a predetermined period of time.
