Abstract: An eNodeB (eNB), user equipment (UE) and method of cell reselection are generally described. While in Radio Resource Control (RRC) Idle mode, the UE may receive via a system information broadcast a cell reselection probability and a cell-specific priority list including a list of neighboring eNBs and their priorities for both macro and small cells operating on at least one frequency different from that of the serving eNB. The UE may generate a random number and compare the random number to the cell reselection probability to determine whether the UE is to reselect. The UE may randomly select among eNBs that have the same, highest priority. The UE may receive a predetermined set of cell reselection criteria from the eNB via a system information broadcast to determine whether or not to perform reselection.

Abstract: Systems, methods, and device for adjusting an operation time of a radio link failure timer are disclosed herein. User equipment (UE) may be configured to communicatively couple to an evolved Universal Terrestrial Radio Access Network (E-UTRAN). The UE use different radio link failure timer parameters depending on the speed of the UE. The radio link failure timer may run for a longer time for rapidly moving UEs and run for a shorter time for slowly moving UEs. In an embodiment, the UE may scale the radio link failure timer by a scaling factor. In another embodiment, the UE may include multiple radio link failure timers for different speeds. The radio link failure timer parameters for each speed may be specified by the E-UTRAN in a one-to-one communication. The E-UTRAN may determine which parameters to use for each UE based on characteristics of the UE.

Abstract: Technology for providing core network assistance information from a mobility management entity (MME) in an evolved packet core (EPC) is disclosed. An average radio resource control (RRC) connected state time for a UE is determined. An average RRC idle state time for the UE is also determined. An amount of time that the UE spends in cells of the EPC is identified to determine a number of handover procedures between cells in a selected time period. The core network assistance information communicated to a serving eNB of the UE to enable the serving eNB to reduce UE state transitions for the UE.
