CPC Class H04W

A method and an apparatus are provided for controlling a power supplied to an in-vehicle computing device. In the method, a mobile device is discovered, which is capable of communicating via a local area network. After it is determined whether a discovered mobile device is registered, the in-vehicle computing device is pre-booted according to a first condition when the discovered mobile device is registered.

A method of feedback in a wireless transmit receive unit includes providing a precoding matrix index (PMI), error checking the (PMI) to produce an error check (EC) bit, coding the PMI and the EC bit and transmitting the coded PMI and EC bit.

Embodiments of this disclosure provide a node diagnosis apparatus and system. The node diagnosis apparatus includes: a first receiving unit configured to receive notifications related to busyness/idleness of channels reported by other nodes; a first transmitting unit configured to, when the first receiving unit receives a first notification related to busyness/idleness of channels reported by a first node and a second notification related to busyness/idleness of channels reported by a second node and the first node and the second node are in different basic service sets, transmit a control signal to the first node and the second node; a second receiving unit configured to receive one or more first parameters reported by the first node and one or more second parameters reported by the second node; and a first determining unit configured to determine that the first node and the second node are exposed nodes when the one or more first parameters and the one or more second parameters satisfy a predetermined condition. With the embodiments of this disclosure, whether a node is an exposed node may be well identified, with complexity of identification being low, and signaling being simple.

A method for processing data, includes: acquiring data packets having respective serial numbers and transmitted between a first microcontroller unit (MCU) and a second MCU of a smart device, the second MCU being provided in a Wireless Fidelity (Wi-Fi) module of the smart device; and processing and displaying the acquired data packets based on the respective serial numbers so as to debug the second MCU.
