[0057] The information sending method implemented by the network side device has the same technical characteristics as the information response method implemented by the terminal, and specific details can be found in the description of the terminal embodiment, so a detailed description is omitted here.

[0058] Next, the method provided in this application will be described with an example. Example 1

[0059] As shown in Fig. 4a, the antennas of the network side device are arranged as (M, N, P, Mg, Ng) = (4, 8, 2, 2, 2), that is, each panel of the network side device has 4 vertical antenna units and 8 horizontal antenna units, each antenna unit is dual-polarized, the number of panels in the vertical region is 2, and the number of panels in the horizontal region is 2. The panels are grouped according to their geometric positions, so that the first panel 41 and the fourth panel 44 form one group and correspond to panel group 1, and the second panel 42 and the third panel 43 form one group and correspond to panel group 2.

[0060] Step 1: The network side device indicates through DCI that the panel group ID that has been turned off is “2”, that is, panel group 2, which means that the network has turned off the second panel 42 and the third panel 43 at this time. As shown in FIG. 4b, the second panel 42 and the third panel 43 are indicated by dotted lines in the figure, indicating that they are turned off.

[0061] Step 2: The terminal suspends or cancels the measurement procedure of the CSI-RS for CSI calculation at the ports corresponding to the second panel 42 and the third panel 43. Example 2

[0062] The CSI-RS of the network side device is globally numbered from 1 to 16. After the network side device enters the sleep state, the base station turns off some CSI-RS ports according to a predetermined rule to save power.

[0063] When resources for CSI-RS numbers 1 to 4 are configured in CSI-RS resource configuration (CSI-RS-Resource Config 1) and the gNB instructs the UE to turn off transmission of CSI-RS numbers 2 and 3 or the RS of the corresponding antenna port, the UE performs CSI measurement using CSI-RS-Resource Config 1 and cancels measurement on the resources where CSI-RS numbers 2 and 3 exist.

[0064] CSI-RS-Resource Config 1 includes resources for CSI-RS 1, CSI-RS-Resource Config 2 includes resources for CSI-RS 2, and by analogy, CSI-RS-Resource Config 4 includes resources for CSI-RS 4. When the gNB instructs the UE to turn off transmission of CSI-RS 2 and CSI-RS 3 or the RS of the corresponding antenna port, the UE performs CSI measurement according to CSI-RS-Resource Config 1 and CSI-RS-Resource Config 4, i.e., performs measurement only on resources where CSI-RS 1 and CSI-RS 4 exist. Example 3

[0065] In the SRS spatial relationship (SRS-SpatialRelation) that the network side device configures for the UE through RRC, the SRS is associated with the CSI-RS. When the network enters a power saving state, the network side device turns off the CSI-RS and instructs the UE that this CSI-RS (port) has been turned off.

[0066] When the SRS in the SRS spatial relationship is a periodic SRS, the UE identifies that a CSI-RS is a reference signal related to the SRS, and the relationship is indicated by the SRS spatial relationship information (SRS-SpatialRelationInfo) configured by the network side device. The UE cancels subsequent SRS transmissions according to the port-off time indicated by the network side device.

[0067] When the SRS in the SRS spatial relationship is a semi-persistent SRS, if the semi-persistent SRS resource is activated, the network side equipment sends a deactivation command for the activated SRS resource, and if the semi-persistent SRS resource is not activated, the network side equipment does not send an activation command for the SRS resource, where on may be understood as activation, and off may be understood as deactivation.

[0068] If the SRS in the SRS spatial relationship is a non-periodic SRS, the SRS Request field in the DCI is set to '00', ie, the SRS is not activated, and thus the UE does not need to transmit this SRS. Example 4

[0069] In the SRS-Spatial Relation configured by the network side device for UE 1 through RRC, the SRS is associated with CSI-RS 1. When the network enters a power saving state, it turns off this CSI-RS signal, and thus the network side device directly instructs the UE through DCI signaling to stop transmitting this SRS. For other UEs, it cancels the rate matching in the ZP-CSI-RS corresponding to UE 1 configured by the network.

[0070] According to the information transmission method of the present application, by dynamically turning on and / or off some antenna panels, antenna ports or signals, it is possible to realize power saving of network side equipment, and also to instruct the relevant behavior of the UE side, to reduce or increase the behavior of measurement, transmission and monitoring at the antenna panels, antenna ports, or the behavior of measurement, transmission and monitoring for signals, thereby bringing a certain gain to the UE side.
