Abstract:
1. A method in a user equipment of determining a radio link quality of a radio link, the method comprising: receiving a first type of reference signal; monitoring, at the user equipment, for a first type of control channel, the first type of control channel demodulated based on the first type of reference signal; estimating a first synchronization condition associated with the radio link based on the first type of reference signal, the first synchronization condition being one of a group comprising an out-of-synchronization condition and an in-synchronization condition; acquiring configuration information related to configuration of a second type of control channel, the second type of control channel demodulated based on a second type of reference signal, the second type of reference signal distinct from the first type of reference signal; monitoring for the second type of control channel; estimating a second synchronization condition associated with the radio link based on the second type of reference signal, the second synchronization condition being one of a group comprising an out-of-synchronization condition and an in-synchronization condition; and sending an output from a current layer to a higher layer based on at least one of the estimated synchronization conditions, wherein estimating the second synchronization condition associated with the radio link is further based on energy per resource element information relating to enhanced physical downlink control channel transmission.
