The invention discloses a method and an apparatus in a node used for wireless communication. A first node receives a first CSI reporting configuration, the first CSI reporting configuration comprising a first RS resource set, the first RS resource set being used for channel measurement, the first RS resource set comprising one or more RS resources; receiving a first information block, the first information block being used to determine at least one index; sending the first CSI report; the number of processing units reported by the first CSI depends on whether at least one RS resource in the first RS resource set meets a first condition or not; the first condition comprises association with the at least one index, or the first condition comprises non-association with the at least one index. According to the method, the appropriate number of processing units is adopted for CSI reporting, and the performance of the system is improved.

The invention discloses a method and an apparatus in a node used for wireless communication. And the first node receives the first signaling and the second signaling, and respectively receives the first RS and the second RS in the first time window and the second time window. The first signaling indicates a first TCI state; the second signaling triggers a first RS and a second RS; the first time window and the second time window are mutually orthogonal; the first time slot depends on the first signaling; the second time window is not earlier than the first time slot, and whether the first node receives the second RS in the second time window by using the first TCI state depends on the relationship of the first time slot and the first time window in the time domain; when the first time window is not earlier than the first time slot, the first node receives the second RS in the second time window using the first TCI state. According to the method, the accuracy of channel measurement is ensured, and the CSI reporting precision is improved.

The invention discloses a method, a medium and equipment for upgrading a Linux system to a swan mongolian system, and all directory files of a Linux root file system are completely copied to a new directory / data / linux-rootfs under a root of the swan mongolian root file system. The method comprises the following steps of: after a swan gap operating system is started, modifying an oos-rootfs root directory and a file structure through a shell script, mounting a directory under a Linux root file system directory to a corresponding directory under a swan gap root file system root, linking a file under the Linux root file system directory to a corresponding file under the swan gap root file system root, and on the basis of the swan gap root file system, linking the directory under the Linux root file system directory to a corresponding file under the swan gap root file system. According to the method, a root file system environment required by an original Linux application program is created to realize seamless translation and compatible operation of the application, and the method has the advantages of rapid transplantation, downward compatibility and continuous iteration, and has relatively good practicability.

The invention discloses a method and an apparatus in a node used for wireless communication. A first node receives a first information block, the first information block configuring at least one symbol as downlink; a second information block is received, and whether a symbol configured to be downlink by the first information block is a first type symbol or not depends on the second information block; transmitting a first CSI in a time slot n1, the first CSI depending on measurements obtained based on a transmission opportunity of the first set of resources that is not later than the first reference resource; the time slot n depends on the time slot n1, the first reference resource is defined by the time slot n2 in the time domain, the n2 depends on the n and a first offset, and the first offset is not smaller than a first threshold value and enables the time slot n2 to be the minimum value of an effective time slot; whether one time slot is the valid time slot or not depends on the second information block. According to the method, the CSI reference resource is determined under the condition that the symbols used for uplink and downlink at the same time are configured, and the performance of the system is improved.

The invention discloses a method and an apparatus in a node used for wireless communication. A first node receives a first information block, the first information block configuring at least one symbol as downlink; a second information block is received, and whether a symbol configured to be downlink by the first information block is a first type symbol or not depends on the second information block; receiving a first signaling, wherein the first signaling triggers a first RS; receiving the first RS in a first time slot and a second time slot; wherein the first RS occupies a first symbol group in the first time slot and a second symbol group in the second time slot; the first parameter indicates a first offset, and the first time slot depends on the first signaling and the first offset; each symbol in the first symbol group and each symbol in the second symbol group are either or not the first type of symbols. According to the method, which symbols are occupied by the RS are determined, the reliability of measurement of the first RS is ensured, and the system performance is improved.

This invention relates to the field of motorcycle safety control technology, specifically to a motorcycle wireless diagnostic method based on a vehicle controller safety architecture. The method includes: performing HSM verification on a mobile app's wireless diagnostic connection request via the motorcycle's VCM to establish a bidirectional data communication channel; sending the mobile app's private protocol diagnostic commands to the motorcycle VCM via the bidirectional data communication channel; performing protocol mapping and UDS conversion on the private protocol diagnostic commands via the motorcycle VCM to generate a UDS diagnostic request message; sending the UDS diagnostic request message to the target ECU via the motorcycle VCM, causing the target ECU to perform corresponding diagnostics based on the UDS diagnostic request message; and performing private protocol conversion and encryption on the target ECU's UDS diagnostic response data via the motorcycle VCM, and sending it back to the mobile app via the bidirectional data communication channel to obtain the motorcycle wireless diagnostic result. This invention can reduce the cost of motorcycle wireless diagnostics and ensure the real-time performance and accuracy of motorcycle diagnostics.
