  • Patent number: 9883432
    Abstract: Briefly, in accordance with one or more embodiments, user equipment receives unicast services from a first carrier of a primary serving cell and determines if Multimedia Broadcast and Multicast services (MBMS) services are available on a second carrier based at least in part on information in a broadcast carrier channel that indicates the second carrier or an identification (ID) of the second carrier. 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.

  • Publication number: 20180007641
    Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), and methods are described for generating an extended power headroom report (ePHR) based on an uncertainty associated with a physical downlink control channel communication granting an uplink grant for a physical uplink shared channel communication when the system is configured for simultaneous physical uplink shared channel and physical uplink control channel communications. Some embodiments are structured to generate the ePHR using a type 2 report regardless of the uncertainty associated with the ePHR, while other embodiments generate the ePHR using a reference format. In some embodiments, a UE communicates a timing field with a UE capability communication indicating whether the UE meets timing requirements to avoid uncertainty in ePHR communications.

  • Publication number: 20170311217
    Abstract: A User Equipment (UE) device operates to directly determine a target small cell for access or handover with the assistance of a macro cell network. The UE directly generates the connection and selects which small cell to access from among a subset of small cells chosen of a set of candidate small cells. The UE is provided dedicated assistance information from the evolved node B (eNB) or macro network device. The dedicated assistance information enables the UE to measure data from the candidate small cells within a heterogeneous network environment. The UE shares the measured data and connects directly to the selected small cell for an access or handover operation.
