Abstract: A method by a small cell for wireless communication may include receiving, by the small cell, a wireless Multicast-Broadcast Single Frequency Network (MBSFN) signal from a macro cell, wherein the small cell is characterized by having a transmit power substantially less than each macro cell in a wireless communication network with the small cell. The method may further include obtaining, by the small cell, a measurement value of the MBSFN signal within a radio range of the small cell. The method may further include acting, by the small cell, based on the measurement value. The small cell may be, or may include, at least one of a pico cell, a femto cell, or a home evolved Node B (HeNB).

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 enable user equipment operating in a current cell that provides a multimedia broadcast/multicast service to distinguish between neighboring cells that have different operational characteristics. The presence of a neighboring cell is identified while the user equipment is operating in a first cell and it is determined whether the neighboring cell provides services different from the services provided in the current cell, based on information maintained by the user equipment. The user equipment may move to the neighboring cell to obtain better or different service.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives information from a network for discarding a data packet, identifies a data packet to be transmitted, determines whether the identified data packet is associated with at least one packet filter of a traffic flow template (TFT), and discards the identified data packet based on whether the identified data packet is associated with the at least one packet filter of the TFT. In an aspect, the apparatus identifies a data packet to be transmitted, determines whether the data packet is associated with at least one packet filter of the TFT, deactivates a link flow associated with the data packet based on whether the data packet is associated with the at least one packet filter of the TFT, and provides information to a device to discard the data packet associated with the deactivated link flow.

Abstract: Systems, methods, and devices for inter-network service selection are described herein. Through the use of one or more of device identifiers and device classes, information including a randomization metric can be transmitted to networked devices indicating which devices and/or device classes are permitted or denied to access a given network service. Equipment seeking access may alter the selection based on this information. Equipment providing access may enforce access request based on this information. As an example, selection between eHRPD and LTE may be load balanced based on device class or identifiers.

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.
