Abstract:
A novel key management approach is provided for securing communication handoffs between a UE and two base stations. A UE establishes a secure communication session with a first base station based on a first master session key based on a master transient key. The UE obtains a second base station identifier associated with a second base station and sends a message associated with a handoff to either the first base station or the second base station. The UE generates a second master session key based on at least the master transient key and the second base station identifier. The second master session key is used for secure communications with the second base station in connection with an intra-authenticator handoff from the first base station to the second base station. The UE then moves the secure communication session to the second base station.
Abstract:
An apparatus, a method, and a computer program product are provided in which an information block is generated to include an expression encoded based on a system key and an input. The input includes an area identifier and a time information. The information block is then broadcasted. An apparatus, a method, and a computer program product are provided in which an information block is received that includes an expression encoded based on a system key and an input. The input includes an area identifier and a time information. The information block is decoded based on the area identifier and the time information to obtain the expression.
Abstract:
A UE may move out of range of a network. Accordingly, the UE may use a relay node to communicate. To manage the relay node, a wireless device such as the UE may receive a relay search message from a second UE requesting a relay UE to establish a connection to the network through the relay UE. The UE may transmit a message to a base station informing the base station of the relay search message from the second UE. The UE may receive an initiate relay association procedure message from the base station, the initiate relay association procedure message informing the first UE that the first UE has been selected by the base station to initiate a relay association procedure with the second UE. The UE may transmit a relay association message to the second UE including a request to be the relay UE for the second UE.
Abstract:
The disclosure generally relates to avoiding physical cell identifier (PCI) collision and confusion using LTE-Direct expressions. In particular, a small cell may discover LTE-Direct expressions that include PCIs associated with neighbor small cells and select (or reselect) a local PCI to ensure that the local PCI differs from the PCIs associated with each neighbor small cell. Furthermore, the small cell may detect PCI confusion where multiple neighbors broadcast LTE-Direct expressions with the same PCI and different E-UTRAN Cell Global Identifiers (eCGIs) and/or detect PCI confusion in neighbor small cells where the local PCI matches the PCI used in a neighbor's neighbor and the local eCGI used in the small differs from that used in the neighbor's neighbor. The small cell may additionally broadcast LTE-Direct expressions that include at least the local PCI and eCGI to enable neighbors to avoid PCI collision and confusion in the same manner.
Abstract:
Certain aspects of the present disclosure are generally directed to techniques for selecting a configuration for communication using vehicle to everything (V2X) type communication protocol. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QOS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.

Abstract:
Methods, devices, non-transitory processor-readable media of various embodiments provide for routing Misbehavior Detection Reports from vehicle-to-everything (V2X) onboard equipment to an associated entity. Various embodiments may include storing, within a Misbehavior Report Router resulting from provisioning of a certificate to a V2X onboard equipment, information that enables a Misbehavior Detection Report to be routed to the entity associated with misbehaving V2X onboard equipment, examining a Misbehavior Detection Report received from a reporting V2X onboard equipment to identify a Pseudonym Certificate Authority Misbehavior Report Router of the entity associated with misbehaving V2X onboard equipment, passing the Misbehavior Detection Report to the identified Pseudonym Certificate Authority Misbehavior Report Router, using information in the Misbehavior Detection Report with information stored in the Pseudonym Certificate Authority Misbehavior Report Router to route the Misbehavior Detection Report to the associated entity.
Abstract:
Aspects of the disclosure relate to a system, method, and device for establishing a secure link for vehicle-to-vehicle (V2V) communication. A device may send a service announcement message to at least one other device via sidelink signaling. The service announcement message indicates a capability of the device to perform a service and includes at least a security certificate of the device. The device establishes a secure link with the at least one other device corresponding to the service by establishing a device key between the device and the at least one other device. The device then communicates service data for the service between the device and the at least one other device via the secure link based on the established device key. Other aspects, embodiments, and features are also claimed and described.
Abstract:
A novel key management approach is provided for securing communication handoffs between an access terminal and two access points. An access terminal establishes a secure communication session with a first access point based on a first master session key based on a master transient key. The access terminal obtains a second access point identifier associated with a second access point and sends a message associated with a handoff to either the first access point or the second access point. The access terminal generates a second master session key based on at least the master transient key and the second access point identifier. The second master session key is used for secure communications with the second access point in connection with an intra-authenticator handoff from the first access point to the second access point. The access terminal then moves the secure communication session to the second access point.
Abstract:
The disclosure provides a mechanism where a user equipment (UE) may communicate with a neighbor UE of the UE's neighbor UE by utilizing the UE's neighbor UE as a relay for the communication between the UE and the neighbor UE of the UE's neighbor UE. In an aspect, the first UE receives a discovery message from a second UE, the discovery message including information about 1-hop neighbor UEs of the second UE. The first UE determines to communicate with a third UE based on the discovery message, the third UE being one of the 1-hop neighbor UEs of the second UE. The first UE requests the second UE to operate as a relay for communication between the first UE and the third UE. The first UE communicates with the third UE through the second UE.
