Abstract: A method, an apparatus, and a computer program product for wireless communication at a node are provided. The apparatus receives a multicast-broadcast single frequency network (MBSFN) signal transmitted from a base station, decodes the received MBSFN signal, and retrieves at least one source symbol from the decoded MBSFN signal when the node is capable of retrieving a source symbol. The apparatus also generates at least one redundancy version of the MBSFN signal based on the retrieved at least one source symbol and transmits the at least one redundancy version of the MBSFN signal via MBSFN. Generating a redundancy version of the MBSFN signal includes applying forward error correction (FEC) on the retrieved at least one source symbol to generate at least one repair symbol. Thus, a redundancy version of the MBSFN signal includes the at least one repair symbol and a subset of the at least one source symbol.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In a first configuration, the apparatus is an eNB. The eNB constructs an MCCH change notification, and sends the MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. In a second configuration, the apparatus is a UE. The UE receives a configuration with aggregated carriers including a primary carrier from a primary cell and one or more secondary carriers from one or more corresponding secondary cells, and receives an MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. The first cell and the second cell are each one of the primary cell and the secondary cells.

Abstract: Compression of broadcast data packets is described in which a compressed broadcast data packet is formed by causing at least one field in a packet header to be excluded from the transmitted data packet. The data from the compressed or removed field is data that is otherwise available to a user entity. The user entity receives the compressed broadcast data packet and determines information corresponding to at least one of the eliminated fields in order to process the received broadcast information.

Abstract: Techniques are provided for smooth transition between broadcast/multicast transmission and unicast transmission. A method for managing unicast and multicast services switching in a multi-band/multi-frequency wireless communications system (WCS) capable of both unicast and multicast signaling includes determining whether an aggregate demand for a content provided via dedicated unicast transmissions exceeds a threshold. The method includes switching transmission of the content from the dedicated unicast transmissions on one frequency to a multicast transmission on a second or more frequencies in response to determining that the aggregate demand exceeds the threshold.

Abstract: Access terminals are adapted to facilitate use of modified cell reselection parameters and/or procedures for access terminals exhibiting low or no mobility. An access terminal may employ one or more mobile thresholds to determine whether to perform cell reselection when the access terminal is mobile, and one or more stationary threshold to determine whether to perform cell reselection when the access terminal is stationary or substantially stationary. Methods operational on access terminals include determining the access terminal to be stationary or substantially stationary, and employing one or more stationary thresholds to determine whether to perform a cell reselection when the access terminal is determined to be at least substantially stationary. Other aspects, embodiments, and features are also included.

Abstract: Certain aspects relate to methods and apparatus for discovering whether one or more enhanced capabilities are supported by devices (e.g., user equipment (UE), base station (BS), etc.) in a network. The enhanced capabilities may include, for example, the ability to support certain low latency procedures, enhanced component carrier (eCC) capability, and the like. The devices in the network may perform one or more handover-related procedures (e.g., cell selection/reselection, make-before-break handover, etc.) and/or other procedures (e.g., QoS negotiation, etc.) based, at least in part, on support for the one or more enhanced capabilities.

Abstract: In some cases, V2X systems may send warning messages. The warning messages may be sent over short distances. The warning messages may be useful over wider distances. Some systems may us MBMS from a V2X proximity broadcast. Electronic communications devices, such as UEs may be unaware of the MBMS. A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an RSU. The RSU receive a V2X message from a UE. The RSU may broadcast information associated with the V2X message. The RSU may send the information associated with the V2X message to a network entity for a point-to-multipoint broadcast. The method, an apparatus, and a computer program product for wireless communication may also use V2X messages that include bootstrapping information to tune to an MBMS broadcast.

Abstract: Methods, systems, and devices are described for decreasing user plane latency in a wireless communication system. This may include routing a portion of bearer traffic to or from a UE through a local or serving gateway, or within or between base stations, rather than via the core network. In some examples, techniques for selected internet protocol flow ultra-low latency (SIPFULL) for systems in which users may have subscribed to enhanced services may be employed. The network may, for instance, authorize SIPFULL functionalities for UEs per access point name (APN) based on individual services subscribed by the UE to improve overall quality of service (QoS). In some examples, a UEs latency requirements or SIPFULL authorizations may affect mobility operations.
