FIELD: radio engineering, communication.
SUBSTANCE: invention discloses a method for determining relative grant and absolute grant mapping, the method comprising: when a passive radio network subsystem does not activate an uplink 16QAM operation in a radio link, the passive radio network subsystem mapping absolute grant according to a first absolute grant value mapping relationship table and processing relative grant signalling according to a first scheduling grant table; and when the passive radio network subsystem activates the uplink 16QAM operation in the radio link, the passive radio network subsystem mapping the absolute grant according to a second absolute grant value mapping relationship table and processing the relative grant signalling according to a second scheduling grant table. The present invention further discloses a system for determining relative grant and absolute grant mapping comprising a first processing unit at a passive radio network subsystem side and a second processing unit at the passive radio network subsystem side.
EFFECT: relative grant signalling and absolute grant signalling can be processed based on correlation between the relative grant and absolute grant.
