[0320] FIG6 is a flow chart of a method for determining information length according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a method for determining information length, and the method includes:

[0321] Step S6101: The terminal determines the length of historical information according to the instruction information of the network.

[0322] In some embodiments, point 1, the base station determines the available historical information length based on the first information reported by the UE or the second information related to the model currently used by the UE. The network selects one of the available historical information lengths and indicates it to the UE. The first information may be UE capability information, and the second information may be additional condition information of the model.

[0323] Point 2: The network indicates the length of the historical information through the first signaling. The first signaling may be RRC signaling. In one embodiment, the first signaling is used for CSI configuration, or the first signaling includes CSI configuration information.

[0324] Point 3: The network indicates the length of the historical information through the second signaling, which can be MAC CE signaling or DCI signaling.

[0325] In one embodiment, the second signaling modifies the history information length value indicated by the first signaling.

[0326] In one embodiment, the first signaling indicates multiple historical information length values, and the second signaling selects one of them for indication.

[0327] Step S6102: The terminal determines the length of the historical information.

[0328] Option 1: The first information reported by the terminal, or the second information of the model currently used by the terminal determines the length of the unique historical information that can be used. The first information can be UE capability information, and the second information can be additional condition information of the model.

[0329] Option 2: The terminal reports third information, which indicates the value of the length of the historical information. The third information can be reported via the third signaling MAC CE or the fourth signaling UCI.

[0330] Option 3: The terminal reports the fourth information, which indicates that the length of the historical information needs to be changed. The fourth information can be reported via the third signaling MAC CE or the fourth signaling UCI.

[0331] The length of the historical information in the above steps S6101 and S6102 can be the number of historical CSIs or the length of a period of time. The number of historical CSIs can be different within the time length according to the CSI-RS configuration of the network.

[0332] In the above step S6101, the terminal receives the instruction information from the network. After the instruction information takes effect, the terminal will change the compression behavior of the terminal, as follows:

[0333] If N = 5, the terminal-side encoder W is initially 0. Assuming the UE reports CSI once per slot, the terminal sequentially compresses and reports the CSI for slots 1 to 5 using SFT. At slot 6, the terminal-side encoder W is reset to 0, and the terminal sequentially compresses and reports the CSI for slots 6 to 10 using SFT. Similarly, the terminal resets W to 0 every N = 5 CSI reporting moments.

[0334] If N is changed to 10, the UE will reset W to 0 every N=10 CSI reporting moments.

[0335] The above steps S6101 and S6102 can be used in combination.

[0336] In one embodiment, the terminal indicates the length of the network history information through the third information, and the network indicates whether the terminal can apply the history information length through the fifth information.

[0337] In one embodiment, the terminal indicates to the network through the third information that the length of the historical information needs to be modified, and the network indicates to the UE the value of the length of the historical information through the sixth information.

[0338] The history information length indication information in the above steps S6101 and S6102 has different starting effective times according to different bearer signaling.

[0339] If it is MAC CE signaling, its starting effective time is the first moment after the terminal first feeds back the HARQ-ack containing the MAC CE.
