摘要： A node including processing circuitry configured to: generate anonymized data based at least in part on a first cryptographic key and network data, calculate a coordination vector, generate initialized data based at least in part on the anonymized data, a second cryptographic key and the coordination vector, transmit the initialized data, the random vector, a security policy and instructions to analyze n iterations of the initialized data and the security policy using the random vector and the second cryptographic key, and receive results of the analysis of the n iterations of the initialized data and the security policy using the random vector and the second cryptographic key. The analysis of an m iteration of the n iterations correspond to an analysis of the initialized data with prefix preservation where the analysis of the remaining iterations of the n iterations fail to be prefixed preserved.

摘要： Method and apparatus of a source network device and a destination network device for autonomous transmission are provided in this disclosure. In a source network device, a coordination indicator and a portion of data is transmitted to the destination network device, the coordination indicator identifying a resource coordination zone to coordinate interference resolution. Then, the source network device determines whether an acknowledgement is received from the destination device prior to an allocation of its repeated transmission. When a message is detected in the resource coordination zone and the acknowledgement is received, the source device transmits a further portion of the data to be transmitted. Problem arising from channel interference can be resolved through the provided methods.

摘要： According to certain embodiments, a method in a wireless device includes determining a current coverage enhancement, CE, mode of the wireless device with respect to a first cell and determining an estimated signal quality of the wireless device with respect to the first cell. If the current CE mode is a normal CE mode and the estimated signal quality of the wireless device with respect to the first cell is greater than or equal to an upper threshold, the wireless devices continues to operate in the normal CE mode. If the current CE mode is an enhanced CE mode and the estimated signal quality of the wireless device with respect to the first cell is greater than or equal to a lower threshold and less than the upper threshold, the wireless device continues to operate in the enhanced CE mode. If the current CE mode is the normal CE mode and the estimated signal quality of the wireless device with respect to the first cell is greater than or equal to the lower threshold and less than the upper threshold, the wireless device is reconfigured to operate in the enhanced CE mode. If the current CE mode is the enhanced CE mode and the estimated signal quality of the wireless device with respect to the first cell is greater than or equal to the upper threshold, the wireless device continues to operate in the enhanced CE mode.
