- the NR determines that the corresponding resource base station for the uplink control channel transmitting the feedback response information is jointly indicated by the high layer signaling and the dynamic signaling. That is, a plurality of available resources (time domain, frequency domain, code domain) are pre-configured through high layer signaling, and one of the dynamic signaling indicates one for actual transmission. Since the resource time-frequency domain size is semi-statically configured by higher layer signaling, flexibility is limited. When the UCI size of the actual transmitted uplink control signaling is in a very large range, the UCI may be wasted by using the pre-configured resource.
