DATA TRANSMISSION METHOD, TERMINAL DEVICE AND NETWORK DEVICE
First Claim
1. A data transmission method, comprising:
- determining, by a terminal device, a Resource Block Group (RBG) size corresponding to a transmission bandwidth used by the terminal device according to the transmission bandwidth and a corresponding relationship between the transmission bandwidth and the RBG size;
receiving, by the terminal device, a bitmap borne in downlink control information sent by a network device, wherein the bitmap comprises M bits, wherein M is a positive integer;
determining, by the terminal device, a target RBG for data transmission from N RBGs within the transmission bandwidth according to values on N bits from the M bits, wherein N is determined according to the transmission bandwidth and the RBG size, and N is a positive integer less than or equal to M; and
transmitting, by the terminal device, the data with the network device on the target RBG.

Abstract
Disclosed are a data transmission method, a terminal device and a network device. The method includes: determining, by a terminal device, a Resource Block Group (RBG) size corresponding to a transmission bandwidth used by the terminal device according to the transmission bandwidth and a corresponding relationship between the transmission bandwidth and the RBG size; receiving, by the terminal device, a bitmap borne in downlink control information sent by a network device, the bitmap including M bits and being a positive integer; determining, by the terminal device, a target RBG for data transmission from N RBGs within the transmission bandwidth according to values on N bits from the M bits, N being determined according to the transmission bandwidth and the RBG size and being a positive integer less than or equal to M; and transmitting, by the terminal device, the data with the network device on the target RBG.
