Embodiment 1
[0030] see figure 2 , figure 2 It is a schematic flowchart of a CSI measurement method provided by an embodiment of the present invention. Wherein, the method may include the following content.
[0031] 201. The terminal receives Rank information sent by a base station, where the Rank information is used to measure CSI.
[0032] In the embodiment of the present invention, the terminal may be a mobile phone, a personal digital assistant (PDA), etc., or other communication equipment, which is not limited in the embodiment of the present invention.
[0033] Wherein, in step 201 above, receiving the Rank information sent by the base station by the terminal may be implemented in various ways, and the embodiments of the present invention will be described in detail later.
[0034] 202. The terminal uses the Rank information sent by the base station to perform CSI measurement.
[0035] In the embodiment of the present invention, the Rank information sent by the base station can...
Embodiment 2
[0105] see Figure 5 , Figure 5 It is a schematic flowchart of another CSI measurement method provided by an embodiment of the present invention. Among them, the method may include the following:
[0106] 501. The base station determines Rank information corresponding to the terminal, where the Rank information is used to measure CSI.
[0107] For example, the base station may determine the Rank information corresponding to each terminal according to empirical values, or determine the Rank information corresponding to each terminal according to a preset strategy, which is not limited in this embodiment of the present invention. Wherein, the Rank information corresponding to each terminal determined by the base station may be the same or different.
[0108] 502. The base station sends rank information corresponding to the terminal to the terminal.
[0109] As an optional implementation manner, the base station may send the Rank information corresponding to the terminal to ...
Embodiment 3
[0121] see Figure 6 , Figure 6 It is a schematic structural diagram of a terminal device provided by an embodiment of the present invention. The terminal device provided in Embodiment 3 of the present invention may be used to implement the method for measuring CSI described in Embodiment 1 above. Such as Figure 6 As shown, the terminal device may include: a receiving unit 601 , a measuring unit 602 and a sending unit 603 . Wherein, the receiving unit 601 receives the Rank information sent by the base station, wherein the Rank information is used to measure CSI; the measuring unit 602 uses the Rank information received by the receiving unit 601 to perform CSI measurement; the sending unit 603 reports to the base station that the measuring unit 602 measures Get the CSI.
[0122] As an optional implementation manner, the receiving unit 601 may receive Rank information delivered by the base station through DCI; wherein, the Rank information may be expressed in a bit form. ...
