Claims 12, 24, Liu discloses generating the CSI report using the CSI processing unit resources (generating and transmitting CSI report using the CSI processing resources; abstract; Preferably, the second information includes information of a start time point and a cycle of the first feedback period; and the second information is transmitted through DCI carried by a PDCCH ; ¶16; Preferably, the third information includes information of a start time point and a cycle of the second feedback period; and the third information is transmitted through DCI carried by a PDCCH ; ¶17; For example, when the number N of the models indicated by the first information is greater than 1, the second information may include direct indication to the models that need to be used; and when the second information does not include the direct indication to the used models, the models adopted by the terminal are determined according to the CSI pilot configuration which is currently used by the network device ; ¶72). Claim 13, analyzed with respect to claim 1, the further limitation of claim 13 disclosed by Liu a wireless transmit/receive unit (WTRU) (terminal device; Fig. 11, el. 700) comprising a processor (Fig. 11, el. 701) and a transmit/receive unit (Fig. 11, el. 704) ( FIG. 11 is a block diagram of a terminal device in another embodiment of the present disclosure. The terminal device 700 includes at least one processor 701, a memory 702, a user interface 703 and at least one network interface 704. All components in the terminal device 700 are coupled together through the bus system. The bus system is configured to achieve connection and communication between the components. The bus system includes a data bus, a power bus, a control bus and a state signal bus ; ¶145).
