Abstract

Wireless communications are described. Failure recovery associated with resource(s) may be used. A wireless device may select, based on a determined failure, a suitable candidate resource for cell(s), such as secondary cell(s). Configuration parameters may lack at least one parameter associated with candidate resource(s). Based on the configuration parameters lacking the at least one parameter associated with candidate resource(s), the wireless device may use a default set of resource(s) for a candidate resource selection or may indicate that no suitable candidate resource has been determined. At least one parameter associated with candidate resource(s) may be indicated during a first failure recovery procedure. The wireless device may stop the first failure recovery procedure and may initiate a second failure recovery procedure.
