    Abstract: Systems and methods for improved inter-frequency measurement are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The eNB may determine a measurement pattern indicating when the UE should perform inter-frequency measurements. The measurement pattern may be selected such that the UE performs measurements more often than once per measurement cycle. The measurement pattern may be selected to balance timing requirements for the UE with increased power consumption that may result from more frequent measurements. The eNB may determine the measurement pattern based on an estimate of UE speed and a number of frequencies to be monitored. A default pattern may be used if the UE speed and/or number of frequencies do not exceed predetermined thresholds.

    Abstract: Adaptive implementation of multiple measurement gap patterns (MGPs) is discussed. One example apparatus can be employed within an eNB, comprising a processor determining a first MGP associated with a first set of one or more carriers and a distinct second MGP associated with a second set of one or more carriers; determining a schedule for a user equipment (UE) associated with the first MGP and the second MGP; and assigning a priority to each carrier of the first set and the second set; transmitter circuitry transmitting to the UE one or more messages that configure the first MGP, the second MGP and the schedule, and transmitting one or more messages that indicate the assigned priorities and the carriers of the first set and the second set; and receiver circuitry receiving carrier measurement(s) from the UE associated with at least one carrier of the first set or the second set.

    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.
