[0050] Example one
[0051] In view of the problem that the related art does not support the simultaneous transmission of CSI of multiple serving cells and / or multiple CSI-RS resources, an embodiment of the present invention provides a terminal including a channel state information (CSI) transmission device .
[0052] image 3 It is a schematic structural diagram of a channel state information sending device according to an embodiment of the present invention, such as image 3 As shown, the device includes: an acquisition module 30 for acquiring N physical uplink shared channel PUSCH resources for sending channel state information CSI, where N is an integer greater than or equal to 1; a sending module 32, coupled with the acquiring module 30, According to a predetermined rule, the CSI is sent on the N PUSCH resources.
[0053] In an implementation manner of the embodiment of the present invention, the obtaining module 30 obtains the N PUSCH resources in at least one of the following...

[0085] Example two
[0086] Figure 5 Is a flowchart of a method for sending channel state information according to an embodiment of the present invention, such as Figure 5 As shown, the method includes the following steps (step S502-step S504):
[0087] Step S502: The terminal obtains N physical uplink shared channel (PUSCH) resources for transmitting channel state information (CSI), where N is an integer greater than or equal to 1;
[0088] Step S504: The terminal sends the CSI on the N PUSCH resources according to a predetermined rule.
[0089] The PUSCH resource in step S502 can be obtained in one or more of the following ways:
[0090] Manner 1: High-level signaling configures PUSCH resources for sending CSI, and obtains the PUSCH resources from high-level signaling;
[0091] Manner 2: Downlink control information (DCI) indicates the PUSCH resource for sending CSI, and acquires the PUSCH resource according to the indication of the DCI;
[0092] Manner 3: The downlink control informa...

[0125] Corresponding to the foregoing method for sending channel state information, an embodiment of the present invention also provides a method for acquiring channel state information. Image 6 Is a flowchart of a method for acquiring channel state information according to an embodiment of the present invention, such as Image 6 As shown, the method mainly includes the following steps (step S602-step S604):
[0126] Step S602: The base station provides N physical uplink shared channel (PUSCH) resources for transmitting channel state information (CSI) for the terminal;
[0127] Step S604: The base station obtains the channel state information sent by the terminal on the N PUSCH resources;
[0128] The base station provides N PUSCH resources for sending CSI through at least one of the following methods: the base station configures the N PUSCH resources for the terminal through high-level signaling; the base station uses downlink control information DCI indicates...
