Optionally, the first information is SR information or periodic channel state information.
Optionally, the second information is feedback information, uplink data or aperiodic channel state information.
It is to be understood that the second information is information corresponding to the control signaling, that is, the second information is related to the control signaling. For example, the second information may be information scheduled by the control signaling, information triggered by the control signaling, feedback information to the control signaling, or the like.
For example, the second information may be the uplink data scheduled by the control signaling; or the second information may be the aperiodic channel state information (for example, aperiodically transmitted Channel State Information Reference Signal (CSI-RS)) triggered by the control signaling; or the second information may be the feedback information (for example, an ACK or a NACK) to the control signaling, and is configured to give a feedback to the control signaling.
The first information is information unrelated to the control signaling, and the first information is transmitted independently of the control signaling, and is not information scheduled on the basis of the control signaling or transmitted for the control signaling. For example, the first information may be an SR; or the first information may be periodic channel state information (for example, periodically transmitted CSI-RS, here, a transmission period of the CSI-RS may be set for the terminal device by a network in advance); or the first information may be other information not scheduled on the basis of the control signaling.
