Abstract
A method and an apparatus for uplink transmission control are disclosed. According to an embodiment, a base station determines a channel metric for indicating uplink channel condition between the base station and a terminal device. The base station determines an uplink transmission format that is to be used for an initial transmission from the terminal device, based on the channel metric such that a spectrum efficiency for the initial transmission can be maximized.
Claims18
A method implemented at a base station, the method comprising:
- determining a channel metric for indicating uplink channel condition between the base station and a terminal device;
- determining an uplink transmission format that is to be used for an initial transmission from the terminal device, based on the channel metric such that a spectrum efficiency for the initial transmission can be maximized;
- determining, for a retransmission for the initial transmission, an amount of residual mutual information, MI, which is to be transmitted in the retransmission;
- and
- determining an amount of uplink transmission resource that is to be used for the retransmission from the terminal device, based on the channel metric and the amount of the residual MI.
