Abstract: In an embodiment, an apparatus to be employed in a user equipment (UE) is described. The apparatus includes configuration circuitry operable to determine, based on one or more configuration information messages, a measurement gap for a master evolved Node B (MeNB) that is operable to provide a master cell group (MCG) that is asynchronous with a secondary cell group (SCG) of a secondary evolved Node B (SeNB), wherein subframe boundaries of the MCG are different from subframe boundaries of the SCG; and radio frequency (RF) control circuitry operable to cause RF circuitry to be tuned, at a beginning of the measurement gap based on a subframe boundary of the MCG, to start inter-frequency measurements, wherein the RF circuitry is to be used to transmit or receive data in a serving cell of the MCG and in a serving cell of the SCG. Other embodiments are also described and claimed.

Abstract: An eNodeB (eNB) and user equipment (UE) are provided that detect whether the UE is in coverage enhancement mode and if so uses a modified version of the Radio Link Control (RLC) configuration in communications between the eNB and UE. Detection mechanisms may differ between the eNB and UE and may include direct signaling between the eNB and UE, the ability to receive control signaling only through particular modified signaling procedures, low power of certain received control signals or lack of response to certain control signals within various predetermined time periods. The modified RLC configuration permits a smaller amount of data than a standard RLC configuration to be transmitted by a transmitting device before a receiving device is able to be polled for information regarding reception by the receiving device of the transmitted data.

Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed.

Abstract: Embodiments have a master eNB with a control plane and optional data plane to user equipment and a secondary eNB with a data plane to the user equipment. The user equipment thus uses both the master eNB and the secondary eNB for data communications while receiving control information from only the master eNB. The master eNB and secondary eNB are connected with an X2 interface. When the secondary eNB desires to refresh its security key, it informs the master eNB using the X2 interface. The master eNB then uses its control plane with the user equipment to initiate a security key refresh for the secondary eNB.

Abstract: Apparatuses and methods for providing multimedia broadcast multicast service (MBMS) on carriers of a new carrier type (NCT) are described herein. A user equipment (UE) may transmit a message to indicate an interest in receiving MBMS transmissions on a target cell that operates on a first carrier of a first carrier type on which cell-specific reference signals (CRSs) are suppressed at one or more downlink subframes of a downlink frame. The UE may receive, in response to transmitting the message, identification information of a notification cell on which to receive MBMS control information change notification for the target cell. The UE may receive MBMS traffic from the target cell using the MBMS control information received from the notification cell. The UE may receive the MBMS control information on a second carrier of a second carrier type different from the first carrier type.

A method performed by circuitry of a User Equipment (UE) may include connecting at a UE, to a Master eNB (MeNB) and connecting to a Secondary eNB (SeNB). The method may include determining at the UE, that one of the connections has a Radio Link Failure and determining at the UE, that the other of the connections remains connected to the UE. The method may include refraining from initiating a Radio Resource Control (RRC) re-establishment procedure while at least one of the connections does not have a radio link failure.
