4 results about "Period length" patented technology

The application relates to the technical field of data processing, and discloses a time series-based data processing method, device, equipment and storage medium, the method comprises the following steps: determining a period length, when current data does not have periodicity, the period length is infinite, based on the data length of batch processing corresponding to a target time window, data processing delay and data generation interval, adjusting the memory size to realize time series-based data processing; when the current data has periodicity, based on the period length, adjusting the memory size to realize time series-based data processing. In the foregoing manner, the application adaptively identifies the period of the current data; the hash value of the current data is calculated; based on the hash value of the current data and the hash values of the previous n windows, the period length of the data is determined, and when the data does not have periodic characteristics, the period is infinite. Through pre-allocation of the memory required for data processing, the frequent creation of new data and the memory recovery of garbage data are reduced, and the performance and reliability of data processing in the Internet of Things are improved.

The invention discloses a database management method and device and a storage medium, and the method comprises the steps: determining the cycle length of a first index based on a data life cycle feature corresponding to the first index; the number of fragments of the first index in a target period is determined, and the target period is a current period or a future period; and creating the first index corresponding to the target period in the database according to the fragment number and the period length. In this way, the resource storage efficiency of the database can be improved.

The invention provides a resource exclusion method during sidelink transmission resource selection, which is applied to a terminal and comprises the following steps: aiming at each period supported by a preset resource pool, determining all historical sidelink control information SCI corresponding to the period in a sensing window according to the period length of the period; and according to all historical SCIs corresponding to each period, performing resource exclusion on the sensing window to obtain a candidate resource set. The invention further provides a terminal, a computer readable medium and a computer program product.

A signal transmission method and an apparatus. A first time domain resource is determined based on a first frequency domain resource, a second frequency domain resource, a period length, and a period index, where the first frequency domain resource is selected from a plurality of candidate frequency domain resources, and the second frequency domain resource is a frequency domain resource for sending a reference signal in a first period or a frequency domain resource determined based on a configuration parameter. The reference signal is sent on the first frequency domain resource and the first time domain resource. In this way, a plurality of candidate frequency domain resources can be provided for reference signals to be periodically sent, to increase a possibility of sending the reference signal, and improve sensing performance.
