Abstract: Methods, systems, and devices are described for recovery from a connection disruption of a user equipment (UE) operating in a multi-carrier mode. The UE may establish a first connection with a primary cell and a second connection with a secondary cell while operating in the multi-carrier mode. A determination may be made that a disruption in the connection with the primary cell has occurred, and the UE may perform a connection reestablishment procedure to attempt to reestablish communications. The connection reestablishment routine may prioritize the secondary cell ahead of one or more other cells for attempting to reestablish communications. The prioritization may be based at least in part on the establishment of the second connection in the multi-carrier mode.

Abstract: Methods, systems, and devices are described for reducing congestion in a wireless communications system. A second connection failure is detected, and a difference between a timestamp of the second connection failure and a timestamp of a first connection failure is calculated. Upon determining that the difference satisfies a first time threshold, information relating to one or more previous connection failures is cleared. A time period is identified. A number of connection failures from a cell that occur during the time period is identified. A determination is made as to whether the number of connection failures satisfies a threshold. Upon determining that the number of connection failures satisfies the threshold, a future connection request may be withheld for a time period.
