COMPUTER-IMPLEMENTED COMBINED METHOD OF MULTIPLE ACCESS IN LPWAN NETWORK BETWEEN SUBSCRIBER STATIONS AND A BASE STATION

摘要

FIELD: information technology.;SUBSTANCE: invention relates to combined methods of multiple access in network LPWAN. Computer-implemented combined method of multiple access in network LPWAN between subscriber stations (SS) and base station (BS) includes stages, at which subscriber station sends request to base station, for each request transmission attempt, a random frequency is selected from the range [RACHmin, RACHmax], the base station receives a request in the given random access range, then each subscriber station in the deterministic access range [DACHmin, DACHmax] assigns a certain sub-range of channel resources in the frequency-time domain, which is in form of a resource grid, divided into a plurality of cells, wherein the resource grid cell corresponds to one subcarrier in the frequency domain [fn, fn+1] and one division in the time domain [tk, tk+1] and forms a resource block allocated to the subscriber station by the base station scheduler, to prevent interference between signals of different subscriber channels, the scheduler has resource units for servicing the subscriber station at the maximum possible distance, while increasing the difference between frequency-time resources for different subscriber stations, base station sends information on distribution of resources in each slot in the form of a schedule to a subscriber station, and according to this schedule access to the BS of the SS is provided.;EFFECT: wider range of hardware for providing combined multiple access to subscriber stations in LPWAN network.;1 cl, 1 dwg
