Claim 14:
15. A method performed by an electronic device on a control device side for a wireless communication system, the method comprising:
receiving, from each terminal device of a plurality of terminal devices of the wireless communication system, information that includes a terminal-specific non-linear precoding capability indicator and terminal-specific channel state information,
wherein the terminal-specific non-linear precoding capability indicator has a length of 1 bit that indicates a first capability value or a second capability value, where the first capability value indicates non-linear precoding capability is supported, and the second capability value indicates non-linear precoding capability is not supported;
based on the received information, performing a terminal device grouping that comprises assigning each terminal device of the plurality of terminal devices to either:
one linear precoding terminal device group, or
one or more non-linear precoding terminal device groups; and

transmitting a terminal-specific non-linear precoding indicator to each terminal device of the plurality of terminal devices that indicates whether that terminal is assigned to the one linear precoding terminal device group or is assigned to one of the one or more non-linear precoding terminal device groups,
wherein the terminal-specific non-linear precoding indicator has a length of 1 bit that indicates a first assignment value or a second assignment value, where the first assignment value indicates assignment to one of the one or more non-linear precoding terminal device groups, and the second assignment value indicates assignment to the one linear precoding terminal device group.
