DATA TRANSMISSION METHOD, TERMINAL DEVICE AND NETWORK DEVICE Russian patent published in 2020 - IPC H04W72/04 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. Method comprises determining, by a terminal device, according to a specific parameter M and the used transmission bandwidth, the RBG size with respect to the transmission bandwidth, where M is a positive integer, receiving a bit image carried in the downlink control information sent by the network device, wherein bitmap includes M bits, determining, according to a value in N bits of M bits, a target RBG for transmitting data in N RBG in transmission bandwidth, wherein N is determined according to transmission bandwidth and size of RBG and N is a positive integer less than or equal to M, and data transmission between target RBG and network device.

EFFECT: technical result consists in enabling determination of size of resource blocks group (RBG), based on a specific parameter and using bit cards with the same size to indicate RBG when using different widths of transmission bands, so that the terminal device can efficiently determine RBG size and reduce detection complexity with search.
