If MBMS services are available on the second carrier, the user equipment at least temporarily switches to the second carrier to receive the MBMS services. The user equipment may provide feedback to the network or the primary serving cell when it starts and stops receiving MBMS services, and then may switch back to the primary serving cell when MBMS services have ended or the user equipment no longer desires to receive MBMS services. | 11-06-2014 |
20140355493 | MULTICAST SERVICE USING UNICAST SUBFRAME - A system and method for multicast servicing in a unicast subframe is disclosed.

20140362829 | EPS BEARER SPLITTING FOR DUAL CONNECTIVITY DEVICES - A User Equipment (UE) may be connected to multiple Enhanced Node Bs (eNBs). The multiple connection allows a UE to have an EPS bearer with multiple bearer paths, one routed through each of the eNBs. One eNB may implement a decision module to switch the bearer path to route incoming packets along a selected bearer path in order to achieve objectives such as maintaining Quality of Service (QoS) for the EPS bearer and/or maximizing overall network throughput. The eNB may gather information and metrics influencing these objectives from the other eNB and UE in order to make better bearer path decisions. The split bearer allows the UE to implement reduced protocol layers and reconfigure the protocol layers to match the bearer path selected by the eNB. | 12-11-2014 |
20150024749 | USER EQUIPMENT AND METHOD FOR PICO-CELL ATTACHMENT AND ATTACHMENT INHIBITING - Embodiments of user equipment (UE) and method for pico-cell attachment and attachment inhibiting are generally described herein. In some embodiments, the UE may determine an angle threshold, calculate an angle between a moving direction and a direction toward the target pico eNB, permit pico-cell attachment if the calculated angle is less than or equal to the angle threshold and inhibit pico-cell attachment when the calculated angle is greater than the angle threshold. In some angle-limitation embodiments, the UE may be configured to receive the angle threshold that is broadcasted by a target pico eNB using the SIBs which may be transmitted on the DL-SCH. In some minimum-distance threshold embodiments, the UE is configured to calculate the angle threshold from a distance threshold and a distance to a target pico eNB. | 01-22-2015 |
20150029955 | SIGNALING MESSAGE SYNCHRONIZATION - Technology for supporting dual connectivity is disclosed. A user equipment (UE) may receive a radio resource control (RRC) reconfiguration message from a macro evolved node B (MeNB). The RRC reconfiguration message may indicate that a secondary cell associated with a secondary eNB (SeNB) is to be added for connection to the UE. The UE may complete an RRC reconfiguration procedure to add the secondary cell. The UE may send a preamble to the SeNB indicating that the UE has completed the RRC reconfiguration procedure. The UE may communicate data with the SeNB after sending the preamble to the SeNB, wherein the UE supports dual connectivity to the MeNB and the SeNB. | 01-29-2015 |
