Claim 14:
15. A communications apparatus, comprising:
a first transmitter, configured to send first configuration information, second configuration information and third configuration information to a terminal device, wherein the first configuration information comprises information about a first non-orthogonal access parameter used to transmit uplink data and information about a first time-frequency resource used to transmit the uplink data, the second configuration information comprises information about a second non-orthogonal access parameter used to transmit first uplink control information on a second time-frequency resource, wherein the first non-orthogonal access parameter is different from the second non-orthogonal access parameter, and the first time-frequency resource overlaps the second time-frequency resource, and
the third configuration information comprises information about a third non-orthogonal access parameter used to transmit second uplink control information on a third time-frequency resource, wherein the first non-orthogonal access parameter is different from the third non-orthogonal access parameter, and
the first time-frequency resource overlaps the third time-frequency resource, the second time-frequency resource overlaps the third time-frequency resource and either only partially overlaps or does not overlap a fourth time-frequency resource carrying a third uplink control information, and the second non-orthogonal access parameter is different from the third non-orthogonal access parameter; and
a receiver, configured to receive uplink signals sent by the terminal device, wherein the uplink signals comprise a signal that is generated based on the first non-orthogonal access parameter and that carries the uplink data, a signal that is generated based on the second non-orthogonal access parameter and that carries the first uplink control information and a signal that is generated based on the third non-orthogonal access parameter and that carries the second uplink control information, the signal that carries the uplink data occupies the first time-frequency resource, and the signal that carries the first uplink control information occupies the second time-frequency resource, and the signal that carries the second uplink control information occupies the third time-frequency resource;
wherein at least one of the first non-orthogonal access parameter or the second non-orthogonal access parameter comprises different non-orthogonal access spreading factors and wherein the third uplink control information is one of a channel quality indicator, precoding matrix indicator and a ranking indicator.
