摘要： A system comprising: a plurality of base stations forming a multicast broadcast single frequency network operating using unlicensed frequency resources; and a network element configured to allocate a transmission period to each of the plurality of base stations, wherein each base station is configured to independently determine whether the unlicensed frequency resources are available for transmission, and transmit a data packet using the unlicensed frequency resources during the allocated transmission period only if the unlicensed frequency resources are determined to be available.

摘要： Systems, methods, apparatuses, and computer program products of preamble sequence management for contention based access are provided. One method may include a user equipment sending a contention based access (CBA) request message, such as a random access procedure (RACH) message, to a network node (e.g., a base station or eNB). The CBA request message may include an indication that the user equipment wants to obtain a preamble for CBA data transmission and is not for full network access. The method may then include receiving an allocation of a preamble for CBA from the network node.

摘要： Methods and apparatus, including computer program products, are provided in one aspect there is provided a method. The method may include detecting, at a first node, an event; generating, at the first node, a message in response to the detected event; and sending, at the first node, the message to at least a second node to enable the second node to determine at least one of a reliability or an importance of the message. Related apparatus, systems, methods, and articles are also described.

摘要： Methods and apparatus, including computer program products, are provided for ultra-reliable communications. In one aspect there is provided a method, which may include receiving, by a first user equipment, a reliability estimate for a communication link before the communication link is at least one of used or established between the first user equipment at a first location and a second user equipment at a second location; and at least one of using or establishing the communication link, when the received reliability estimate exceeds a threshold reliability. Related systems, articles of manufacture, and the like are also disclosed.

摘要： Various communication systems may benefit from an accurate detection method. The method may include determining correlation values between a first sequence of samples and at least one pre-defined sequence, detecting whether at least one first peak exists by comparing the correlation values with at least one first detection threshold. If the at least one first peak exists, the method may further include performing summing of at least a subset of the correlation values and detecting whether at least one second peak exists by comparing the summed correlation values with a second detection threshold.

摘要： In one aspect, there is a method. The method may include receiving an image of a vehicle from a sensor. The image may include identifying information of the vehicle. The method may further include generating an identifier for the vehicle based on the identifying information. The method may also include sending a message to the vehicle. The message may include the generated identifier in order to identify a destination address of the message. The above-noted aspects and features may be implemented in systems, apparatuses, methods, and/or computer-readable media depending on the desired configuration.
