Abstract
A grant-free transmission method, a terminal, and a network device are disclosed. In an embodiment, a grant-free transmission method includes sending, by a network device, information about P dedicated transmission resources used for grant-free transmission to a terminal, wherein P is a positive integer and P≥2, detecting, by the network device, a dedicated transmission resource, and detecting, by the network device, data based on a transmission parameter set corresponding to the dedicated transmission resource when grant-free transmission is detected.
Claims24
A method comprising:
- sending, by a network device to a terminal, information about P dedicated transmission resources that are dedicated to the terminal, the P dedicated transmission resources being used for grant-free transmission and P being a positive integer and P≥2, wherein the P dedicated transmission resources include a first pilot and a second pilot that are dedicated to the terminal, wherein the first pilot corresponds to a first modulation and coding scheme, and wherein the second pilot corresponds to a second modulation and coding scheme different from the first modulation and coding scheme;
- detecting, by the network device, a dedicated transmission resource of the P dedicated transmission resources;
- and
- detecting, by the network device, data based on a transmission parameter set corresponding to the dedicated transmission resource that is dedicated to the terminal when the grant-free transmission is detected, wherein the transmission parameter set comprises a redundancy version corresponding to the dedicated transmission resource, wherein the dedicated transmission resource comprises the first pilot, and wherein the transmission parameter set corresponding to the dedicated transmission resource includes the first modulation and coding scheme corresponding to the first pilot.
