Abstract: Multiple data bearers may be configured for a user equipment (UE) for carrier aggregation and may be split among multiple evolved nodeBs (eNBs). The eNBs may be selected to serve the multiple data bearers for the UE based on various criteria such as channel conditions, loading, and the like. Various eNBs may be selected to serve data bearers for UE on a per data bearer basis, so that a particular eNB may be selected to serve each data bearer of the UE. Each data packet for the UE may then be sent via an appropriate data bearer.

Abstract: Methods, systems, and devices for wireless communication are described. A per-frequency indication providing deployment options for communication with a core network may be used for enhanced cell selection by a user equipment (UE). For example, system information transmitted by a base station may provide information elements that indicate, per radio frequency (or per radio frequency (RF) spectrum band)), deployment options associated with nearby cells. In such cases, the UE may determine whether to access the radio frequencies or RF bands of these cells based on the capabilities of the UE. In some cases, the UE may further determine whether the nearby cells are available based on the availability of a service through those cells. Accordingly, the UE may select one of the radio frequencies or bands corresponding to the cell having a network connectivity configuration that supports the UE's capabilities.

Abstract: Systems and methods for wireless communication are described herein. In one aspect, a method may include establishing, by a first base station, a connection to a User Equipment (UE) and identifying a second base station to which the UE can also connect, determining whether dual connectivity of the UE to the base stations is permitted, and selecting, based on the determining, handing over the UE to the second base station or initiating dual connectivity for the UE. In another aspect, a method may include receiving a request for modifying bearers routed via a first gateway node for dual connectivity of a UE to a master base station and a secondary base station, determining that the modification requires bearers to relocate to a second gateway node, and rejecting the request or relocating all bearers associated with the UE to the second gateway node, based on the determining.

Abstract: Mobile devices may receive page transmissions that include information related to a service for which the mobile device is being paged. The mobile device may be provided with a policy that describes a priority of radio access technologies (RATs) based on the type of service for which the mobile device is being paged. The mobile device, based at least in part on the service information, may access one or more of the wireless communications networks based on the identified service and/or based on the policy. A page transmission may include an indication of a RAT that is to be used for the page response and/or an index into the policy. A base station that transmits a page transmission may include an identifier of a particular network that is to be accessed in response to the page.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more particularly, to methods and apparatus for multicasting traffic using multi-connectivity. A wireless network can send a downlink (DL) packet, which follows one path from a core network entity to a user equipment (UE) under current standards, to multiple base stations (BSs) and from each of the base stations to a UE. The UE receives the DL packet from whichever BS first delivers the DL packet, and then the UE sends a report reporting receipt of the DL packet back to all of the BSs. BSs that receive a report indicating the UE received the packet can drop the packet, even if they have not yet successfully delivered the packet. The same procedure can be used for an UL packet, which can be sent from a UE to multiple BSs, and from the BSs to a core network entity.

Abstract: Methods, systems, and devices for wireless communication are described. The methods, systems, and devices may employ mechanisms for encrypting downlink control channels for jamming resilience. The methods, systems, and devices may include or may be configured to generate and receive a security configuration, obtain a downlink control channel encryption key, transmit a control channel message, and decrypt the transmitted messaged based on the encryption key.

Abstract: Techniques are described for wireless communication. A method of wireless communication at a transmitting wireless device includes generating a first Message Authentication Code (MAC) for a data packet based at least in part on a first security key used to communicate with a receiving wireless device; generating a second MAC for the data packet based at least in part on a second security key used to communicate with a relay user equipment (UE), in which the relay UE is included in a data routing path between the transmitting wireless device and the receiving wireless device; and transmitting the data packet to the relay UE with at least the first MAC and the second MAC.

Abstract: One feature pertains to a method operational at a device. The method includes performing key agreement with a core network device, and generating an authentication session key based in part on a secret key shared with a home subscriber server (HSS), where the authentication session key is known to the core network device. The method further includes generating a mobility session key based in part on the authentication session key, where the mobility session key is known to a mobility management entity (MME) served by the core network device and serving the device. The method also includes cryptographically securing data sent from the device to a wireless communication network using the mobility session key.

Abstract: Methods, systems, and devices for wireless communication at a network entity are described. A user equipment (UE) may obtain identification information for a device and may assist in establishing credentials by which the device accesses a wireless network, e.g., a cellular network. The UE may establish a connection with the wireless network using its own credentials. A device subscription administration server, which may be an entity within the wireless network core, may authenticate the device based on the identification information, which may include registering the device to access the wireless network, e.g., using different credentials than those of the UE, by associating the device identification information with the credentials of the UE. Once registered, the device may communicate with the wireless network. The device subscription administration server may then establish access parameters and communicate them to the UE, which may transmit them to the device over communication link.
