    Abstract: Transfer of Multimedia Broadcast/Multicast Services (MBMS) over a Single Frequency Network (MBSFN) service and idle mode unicast service for a mobile entity from a source base station to a target base station may be managed by a base station or mobile entity of a cellular wireless communications system (WCS). Operations related to the transfer may include obtaining an MBMS status of the mobile entity, and/or obtaining MBMS support information for the base station. A network entity may facilitate MBMS discovery by a mobile entity, by transmitting a data element to the mobile entity including service identifiers mapped to corresponding cell identifiers to indicate respective MBMS services to be broadcast in an WCS area on adjacent cells identified by respective ones of the cell identifiers. The MBMS services may be broadcast within the WCS area using the adjacent cells previously indicated in the data element.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receives at least one of a unicast or a broadcast/multicast communication on a first frequency from a first cell of a serving eNB through a first receive chain. In addition, the UE receives at least one of broadcast/multicast signal, synchronization signal, or reference signal communication on a second frequency from a second cell of the serving eNB through a second receive chain without having received instruction from the serving eNB to receive the at least one of the broadcast/multicast signal, the synchronization signal, or the reference signal communication.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which user equipment performs a circuit-switched fallback procedure to connect to a CDMA2000 network. The CDMA2000 network may be selected by the UE or by the network. A plurality of PLMN IDs may be maintained, where the IDs relate to a network that includes an LTE RAN. Each PLMN ID may be associated with a CDMA2000 network sharing the LTE RAN. A CDMA2000 network may be selected for circuit-switched fallback of a user equipment operating in the LTE RAN. The user equipment may be configured to perform a circuit-switched fallback procedure on the selected CDMA2000 network. The CDMA2000 network may be selected by a mobility management entity responsive to a PLMN selection procedure. The PLMN selection procedure may be performed when the UE reports multiple-operator capability.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an MCE. The apparatus receives a plurality of channel status reports from respective eNBs. In an aspect, each channel status report includes channel information associated with a respective eNB for one of a plurality of channels in a contention based radio frequency band. The apparatus selects a channel for an eNB among the plurality of channels based on the plurality of channel status reports. In an aspect, the selected channel is available to be used for an eMBMS. The apparatus prompts the eNB to provide the eMBMS using the selected channel.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive data from both a source base station and a target base station during handover. For example, the UE may refrain from resetting or reestablishing media access control (MAC) and packet data convergence protocol (PDCP) layer configurations until after a successful access procedure is performed with the target base station. In some cases, a single radio link control (RLC)/PDCP stack may be used during handover procedures. A source base station may, for example, forward data to a target base station after receiving a handover execution message. A UE may identify and resolve any duplicate data sent by both base stations during the transition. Additional signaling may be used (e.g., during the radio resource control (RRC) configuration) to indicate that a UE supports dual link handover.

    Abstract translation: 描述了用于无线通信的方法，系统和设备。 在切换期间，用户设备（UE）可以从源基站和目标基站接收数据。 例如，UE可以在与目标基站执行成功的接入过程之后，避免重新设置或重新建立媒体访问控制（MAC）和分组数据融合协议（PDCP）层配置。 在某些情况下，在切换过程中可以使用单个无线电链路控制（RLC）/ PDCP协议栈。 源基站可以例如在接收到切换执行消息之后将数据转发到目标基站。 UE可以在转换期间识别和解析由两个基站发送的任何重复数据。 可以使用附加信令（例如，在无线电资源控制（RRC）配置期间）来指示UE支持双链路切换。
