Abstract: Systems, methods, apparatuses, and computer program products for a radio resource control connection re-establishment for a wireless system, such as LTE and LTE-A, are provided. One method comprises determining a strongest signal strength cell to a user equipment and comparing the strongest signal strength cell to a list of prepared cells. The method further comprises determining if the strongest signal strength cell is a suitable cell and if it is on the list of prepared cells. The method may further comprise, upon a connection failure, the user equipment attempting re-establishment connection between the user equipment and the strongest signal strength cell if the strongest signal strength cell is a suitable cell and is on the list of prepared cells.

Abstract: The monitoring of control channels, such as the physical downlink control channel, may benefit from the influence of data buffer status information. In certain embodiments, a method includes monitoring a downlink channel (for example, a PDCCH) in active time. The method also includes monitoring an instantaneous status of a data buffer related to a user equipment and/or a base station. The monitoring of the downlink channel is guided by the instantaneous status as presently known.
