For convenience of description, the devices mentioned above are collectively referred to as terminals.

Referring to FIG. 1b, FIG. 1b provides a network structure diagram of a 5G new air interface NR of the fifth generation mobile communication technology. As shown in FIG. 1b, under the new air interface base station (English: New Radio Node B, NR-NB), there may be One or more Transmission Reception Points (TRPs), one or more terminals may exist within one or more TRP ranges.

In 5G, since the measurement and feedback of CSI may include multiple CSI-RS (Channel State Information-reference signal) resources, a variety of report settings. The CSI-RS resources can be divided into periodic CSI-RS, semi-persistent CSI-RS, and aperiodic CSI-RS in time. CSI feedback can be divided into periodic CSI feedback, semi-persistent CSI feedback, and aperiodic CSI feedback. The CSI feedback may include: RSRP (English: Reference Signal Receiving Power) measurement, CQI (English: Channel Quality Indicator), PMI (English: Precoding Matrix Indicator) , RI (English: Rank Indication, rank indication), CRI (English: CSI-RS resource indicator, channel state information reference signal resource indication) and other information.

The flow of the above three types of CIS feedback is described in the following figure. Referring to FIG. 2a, FIG. 2a may be a schematic diagram of a periodic CSI process, where CSI configuration information may be carried in RRC (Radio Resource Control) signaling. Of course, in practical applications, it may also be carried in signaling of other PDCCHs (English: Physical Downlink Control Channel).

Step S201a: The gNB sends RRC signaling to the UE, where the RRC signaling carries the resource configuration port 1, the periodic CSI measurement, and the CSI reporting period tx used by the CSI measurement.

Step S202a: The UE receives the RRC signaling, and periodically measures the CSI information of the port 1.

Step S203: When the reporting period arrives, the UE periodically reports the port 1 through the signaling of the PUCCH (Physical Uplink Control Channel) or the PUSCH (Physical Uplink Shared Channel). CSI information.

Referring to FIG. 2b, FIG. 2b may be a schematic diagram of a semi-persistent CSI process. The CSI configuration information may be carried in the RRC signaling, and may also be carried in the signaling of the PDCCH.

Step S201b: The gNB sends RRC signaling to the UE, where the RRC signaling carries the resource configuration port 1, the semi-persistent CSI measurement, and the duration of the CSI measurement used by the CSI measurement, and the duration is assumed to be the interval [t0, t1] and the CSI. Report period tx.

Step S202b: The UE receives the RRC signaling, and periodically measures the CSI information of the port 1 in the interval [t0, t1].

Step S203b: When the reporting period of the interval [t0, t1] arrives, the UE periodically reports the CSI information of the port 1 by using the signaling of the PUCCH or the PUSCH.

Referring to FIG. 2c, FIG. 2c may be a schematic diagram of an aperiodic CSI process. The CSI configuration information may be carried in the RRC signaling, and may also be carried in the signaling of the PDCCH.

Step S201c: The gNB sends RRC signaling to the UE, where the RRC signaling carries the resource configuration port 1, the aperiodic CSI measurement, and the CSI reporting time t2 used by the CSI measurement.

Step S202c: The UE receives the RRC signaling, and measures CSI information of the port 1.

Step S203c: When the reporting time t2 arrives, the UE periodically reports the CSI information of the port 1 by using the signaling of the PUCCH or the PUSCH.

From the above description, the complexity of the CSI reporting and measurement of the UE can be relatively high, so Simplifying the CSI measurement and reporting of the UE can reduce the signaling overhead and reduce the power consumption of the UE. In the 5G system, due to the existence of multiple wave speeds (English: beam) and high-speed mobile scenarios, different resource settings and report settings may be frequently configured to the UE through RRC configuration. CSI measurement and feedback to reduce UE power consumption and signaling overhead is an urgent problem to be solved.

Referring to FIG. 3, FIG. 3 provides a channel state information measurement and feedback method, which is implemented in a network architecture as shown in FIG. 1a. The base station in the network side device in this embodiment takes gNB as an example. As shown in Figure 3, the following steps are included:

Step S301: The UE sends indication information of the recommended value T of the feedback waiting window to the gNB.

The foregoing step S301 can be implemented in multiple manners. For example, in an optional solution of the embodiment of the present invention, the indication information may be directly the recommended value T, and the recommended value T may be reported as a capability information when the UE capability is reported. . For another example, in the optional solution of the embodiment of the present invention, the indication information may also be a terminal type. For example, in another optional solution of the embodiment of the present invention, the indication information may be a terminal type and a bitmap (bitemap) index. Specifically, the bitmap index may be carried in the uplink signaling of the UE, and the present invention The specific implementation manner does not limit the specific manifestation of the foregoing uplink signaling. In addition, the recommended value T may be a fixed value. Of course, in the actual application, the recommended value T may also be confirmed by the UE according to the current network environment. The specific implementation manner of the present invention does not limit the determining manner of the recommended value T and Specific value.

Step S302: The gNB receives the indication information of the recommended value T of the feedback waiting window, and acquires the recommended value T according to the indication information.

The implementation method of the above step S302 can be:

If the indication information is the recommended value T, the gNB parses the indication information to determine the recommended value T.

If the indication information is a terminal type, the gNB parses the indication information to determine the terminal type, and determines a recommended value T corresponding to the terminal type from a mapping relationship between the pre-configured type and the recommended value T.

If the indication information is the terminal type and the bitmap index, the gNB parses the indication information to determine the terminal type and the bitmap index, and the gNB determines the first bitmap corresponding to the type according to the terminal type, according to the bitmap index from the first The recommended value T corresponding to the bitmap index is queried in the bitmap.

Step S303, the gNB determines the actual value W of the feedback waiting window according to the recommended value T, and the gNB will The confirmation indication of the actual value W is sent to the UE.

The implementation method of the foregoing step S303 may specifically be:

The gNB determines the actual value W=T of the feedback waiting window and sends an acknowledgement indication to the UE. The acknowledgement indication may specifically be a response message, and the response message may be an ACK message. Of course, the response message may also be expressed in other forms. For example, the acknowledgement indication is represented by an extended field of downlink signaling, and the extended field may be Carrying 1 bit of acknowledgment information, of course, the extension field can also carry a string of special bit value acknowledgment information, such as 10 1, 11 zeros and the like.

Of course, the W confirmed by the gNB may also be different from the T, and the gNB may determine W according to the recommended value T by a preset policy. The preset policy may be set by the manufacturer. For example, the gNB may determine W according to the current channel quality of the UE and the preset channel quality ratio. If the ratio is greater than 1, determine W=TB*C, if the ratio is smaller than 1, then determine W = T + B * C, where C can be an empirical value (generally a constant, of course, it can also configure different constant values according to different terminal types), which B can be a ratio. Of course, the gNB can also determine W according to the recommended value T according to other parameters, for example, adjusting the recommended value T according to the speed of the UE, and the specific embodiment of the present invention does not limit the specific confirmation manner of the foregoing W. When W≠T, the confirmation indication of the actual value W may be W.

Step S304: The UE receives an acknowledgement indication of the actual value W sent by the gNB, and determines the actual value W according to the determination indication.

The implementation method of the foregoing step S304 may specifically be:

If the confirmation indication includes the response information, it is determined that T=W, and if the confirmation indication does not include the response information, the actual value W included in the confirmation indication is extracted.

Step S305: The UE receives CSI measurement configuration information sent by the gNB, and the UE performs CSI measurement of the CSI measurement configuration information to obtain CSI measurement information.

Optionally, the CSI measurement configuration information in the foregoing step S305 may include: one or any combination of the resource configuration used by the CSI measurement and the CSI measurement mode or the CSI reporting mode configuration information. That is, the measurement configuration information may include: a resource configuration used by the CSI measurement, a CSI measurement mode, a resource configuration used by the CSI measurement, a CSI reporting mode configuration information, a resource configuration used by the CSI measurement, a CSI measurement mode, and a CSI reporting mode configuration. information.

The foregoing CSI measurement mode may specifically be: periodic CSI measurement, semi-persistent CSI measurement, or aperiodic. CSI measurement. The CSI reporting mode configuration information may be: a CSI reporting period value or a CSI reporting time.

The CSI measurement configuration information in the foregoing step S305 may be carried in the RRC signaling or the PDCCH and sent to the gNB.

Step S306: After waiting for the feedback waiting window actual value W, the UE sends the CSI measurement information to the gNB.

The implementation manner of the foregoing step S306 may specifically be:

The UE does not report the CSI measurement in the feedback wait window actual value W. For example, if the W=10 ms, the UE does not report the CSI measurement information within 10 ms, and the start time of the feedback waiting window may be confirmed according to the CSI measurement configuration information. For example, the start time may be the receiving time of the CSI measurement configuration information. Of course, in an actual application, the start time may also be a time when the receiving time of the CSI measurement configuration information is delayed by a time tm.

Optionally, the foregoing CSI measurement information may be carried in a PUCCH or a PUSCH and sent to the gNB.

According to the steps shown in FIG. 3, the combination of different steps may form a channel state information measurement and feedback method on the network side and the terminal side. Specifically, step S301, step S304-step S306 may constitute channel state information measurement on the terminal side. And the feedback method, step S302 and step S303 can form a channel state information measurement and feedback method on the network side.

With the technical solution shown in FIG. 3, after the UE reports the recommended value T of the feedback waiting window, the base station determines the actual value W according to the recommended value T, and informs the UE of the actual value W so that the UE receives the CSI sent by the base station. After the configuration information is received, the CSI measurement information is sent to the gNB after waiting for w, so that the UE does not report the CSI measurement information to the gNB in the W interval, thereby reducing the number of reports of the CSI measurement information, thereby reducing the signaling overhead. At the same time, it also reduces the power consumption of the UE.

Referring to FIG. 3a, FIG. 3a is a channel state information measurement and feedback method. The method is implemented in a network architecture as shown in FIG. 1a. The method uses a periodic CSI measurement as an example. The method is as shown in FIG. 3a and includes the following. step:

Step S301a: The UE reports capability information to the gNB, where the capability information includes a recommended value T=8ms of the feedback waiting window.

Step S302a, gNB parsing the capability information to confirm the recommended value T, and determining the feedback waiting window. The actual value W=T, and the ACK information is sent to the UE.

Step S303a: The UE receives the ACK information, and determines an actual value of the feedback waiting window W=T=8 ms.

Step S304: The UE receives the RRC signaling sent by the gNB, where the RRC signaling includes: the resource configuration port 1, the periodic CSI measurement, and the CSI reporting period tx=2 ms used by the CSI measurement, and the UE performs CSI measurement on the port 1 to obtain the port 1 CSI measurement information.

Step S305a: After waiting for 8 ms, the UE sends the CSI measurement information of the port 1 to the gNB through the PUCCH.

Step S306a: After waiting for 8 ms, the UE periodically performs CSI measurement to obtain CSI measurement information of port 1, and sends CSI measurement information once every 2 ms through PUCCH.

Referring to FIG. 3a, after determining the actual value W of the feedback waiting window, after receiving the CSI measurement configuration information of the base station, the CSI measurement is performed, and after waiting for W, the CSI measurement information is sent to the base station and the periodic measurement is resumed. Feedback CSI.

Referring to FIG. 3b, FIG. 3b is a channel state information measurement and feedback method. The method is implemented in a network architecture as shown in FIG. 1a. The method takes a semi-persistent CSI measurement as an example, and the duration is 20 ms. As shown in Figure 3b, the following steps are included:

Step S301b: The UE sends the terminal type R9 and the bitmap index 11 to the gNB.

Step S302b: The gNB determines the first bitmap corresponding to the terminal type R9, and confirms the recommended value T=6ms corresponding to the bitmap index 11 according to the first bitmap, and adjusts the T value to obtain the feedback waiting window actual value W=8ms. Sending the W with an acknowledgment indication to the UE.

Step S303b: The UE receives the confirmation indication, and the analysis confirmation instruction obtains the actual value of the feedback waiting window W=8 ms.

Step S304b: The UE receives the RRC signaling sent by the gNB, where the RRC signaling includes: the resource configuration port 1 used for the CSI measurement, the semi-persistent CSI measurement time 20 ms, and the CSI reporting period tx=2 ms, and the UE performs CSI measurement on the port 1 CSI measurement information for port 1.

Step S305b: After waiting for 8 ms, the UE sends the CSI measurement information of the port 1 to the gNB through the PUCCH.
