1. A user equipment (UE) comprising:

  • a communications interface to;

    process a first downlink (DL) signal from a secondary evolved NodeB (SeNB) that the UE is to communicatively couple with over a first radio link; and

    process a second DL signal from a master evolved NodeB (MeNB) that the UE is to communicatively couple with over a second radio link, wherein the first radio link and the second radio link are radio links that at least partially overlap in time in a dual connectivity network; and

    radio resource control (RRC) circuitry coupled with the communications interface, the RRC circuitry to generate, based on a first radio link monitoring (RLM) parameter that is related to the first radio link and the first DL signal and that is different than a second RLM parameter that is related to the second radio link and the second DL signal, a first indication of a quality parameter related to the first radio link;

    wherein the first RLM parameter is a value of a first timer that is related to the first radio link and the second RLM parameter is a value of a second timer that is related to the second radio link and the first timer is different from the second timer; and

    wherein the second timer is a t310 timer and the first timer is a timer that is different than the t310 timer.
