Detailed Description

The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the application, fall within the scope of protection of the application.

Terms related to the embodiments of the present application will be described below.

1. Energy saving for network side devices

At present, in an NR system, a plurality of shutdown techniques can be adopted by network side equipment, so that the electric quantity consumption of the network side is reduced, and the purpose of energy conservation is achieved. Among other things, the plurality of shutdown techniques may include: symbol off technology, carrier off technology, channel off technology, and deep sleep technology.

Symbol off technology principle:

the network side device can turn off a Power switch of a Power Amplifier (PA) at the symbol period time when no data is transmitted, and turn on the PA Power switch at the symbol period time when data is transmitted, so as to reduce system Power consumption under the condition of ensuring that service is not affected.

Note that, since the symbol off technique uses the discontinuous transmission (Discontinuous Transmission, DTX) technique, the symbol off technique may also be referred to as a DTX power saving technique.

Carrier wave cut-off technology

The network side equipment can migrate the UE served by the network side equipment to the basic coverage layer cell and turn off the capacity layer cell under the condition of lower load of the capacity layer cell so as to achieve the effect of energy conservation. Under the condition that the load of the base coverage layer cell is increased, the network side equipment can wake up the capacity layer cell and migrate the served part of UE to the wake-up capacity layer cell.

Channel shutdown techniques

When the load of the cell is low, the network side equipment can close the transmitting channel (or the receiving channel) by adopting different granularity according to the load level of the cell so as to realize energy saving. After the channel is turned off, the network side equipment can compensate the work rate of the broadcast and data channels so as to ensure the coverage and performance of the network.

2. Airspace energy-saving technology of network side equipment

Currently, in NR systems, network-side devices are provided with large-scale multiple-input multiple-output (Massive Multiple Input Multiple Output, mMIMO) arrays. However, the power consumption of the mMIMO array is higher, so the network side device can close part of ports of the mMIMO array when no data is transmitted, so as to reduce the power consumption of the network side device.

3. Priority of CSI (and/or CSI reports)

The effect of the priority of CSI (and/or CSI reports) is to determine which reporting procedure of CSI (and/or CSI reports) is performed by the terminal in case of insufficient capability (and/or time-frequency resources) of the terminal. For example, the terminal may perform reporting procedures of some CSI (and/or CSI reports) with the highest priority.

Wherein, when the capability of the terminal (for example, CSI calculating unit (CSI Processing Unit, CPU)) is insufficient, the terminal may not update some CSI with the lowest priority, i.e. do not perform calculation of some CSI; or when the time-frequency resources of the terminal are limited, the terminal may discard some CSI with the lowest priority.

The CSI reporting method, device, terminal and medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Currently, when the load of the network side device is low, the network side device can switch from 32ports to 8ports through the port number of the ports, for example, closing part of the ports, so as to achieve the purpose of energy saving. However, since frequent port switching may cause inaccuracy in the previously configured CSI report setting and CSI-RS resource configuration, in order to ensure accuracy of CSI tracking, the terminal needs to report multiple pieces of CSI related information (i.e., CSI or CSI report) corresponding to multiple ports, so that the network side device may obtain CSI related information needed by the network side device from the multiple pieces of CSI related information. However, since the CSI reporting process in the related art is limited by the processing capability of the terminal and the time-frequency resource, reporting of multiple CSI in one CSI report is not supported, and thus, a situation that reporting of CSI-related information is not complete or timely may occur, and thus, a situation that the network side device cannot acquire the required CSI-related information may occur.

However, in the embodiment of the present application, the terminal may determine the priority of multiple CSI-related information, where the priority of each CSI-related information is related to the energy-saving state and/or the non-energy-saving state of the network side device corresponding to each CSI-related information, and when the state of the network side device dynamically changes, the priority of CSI reporting also changes along with the change of the state of the network side device, so as to ensure that the CSI-related information that the terminal preferentially reports is the CSI-related information that is the most needed and the most up-to-date by the network side device, and therefore, the network side device may directly perform optimal resource scheduling according to the most up-to-date CSI-related information, thereby improving the communication performance of the terminal.

Fig. 2 shows a flowchart of a CSI reporting method provided by an embodiment of the present application. As shown in fig. 2, the CSI reporting method provided by the embodiment of the present application may include the following steps 101 and 102.

Step 101, the terminal determines the priority of at least two target objects.

In an embodiment of the present application, the at least two target objects include at least one of: at least two target CSI, at least two target CSI reports.

In the embodiment of the application, in at least two target CSI reports, different target CSI reports are associated with different CSI-RS resource sets.

It should be noted that, the above "different target CSI reports are associated with different CSI-RS resource sets" may be understood as: the CSI in different target CSI reports is generated by measuring the CSI-RS resource sets with different configurations by the terminal.

Wherein, the CSI-RS resource sets with different configurations have different numbers of on ports or off ports, or different time-frequency resource positions, or have different spatial characteristics, different periods, and so on.

Optionally, in an embodiment of the present application, different target CSI among the at least two target CSI correlates with different measurement hypotheses. Wherein the measurement hypothesis may include at least one of: measuring location, measuring resources, reporting content, etc. For example, different target CSI may be associated with different sets of CSI-RS resources.

It should be noted that, the above "different target CSI may be associated with different CSI-RS resource sets" may be understood as: different target CSI are generated by the terminal by measuring different CSI-RS resource sets.

In the embodiment of the application, at least two target CSI are the CSI in the same CSI report, or at least two target CSI are the CSI in at least two target CSI reports.

Wherein, in the case that the at least two target CSI are CSI in the same CSI report, the at least two target CSI may be CSI in any one of the at least two target CSI reports.

In the case where the at least two target CSI are CSI in at least two target CSI reports, one target CSI may be included in each target CSI report; or at least two target CSI may be included in each target CSI report.

Optionally, in the embodiment of the present application, the terminal may receive CSI report configuration from the network side device, where the CSI report configuration is used to configure at least two target objects, so that the terminal may generate at least two target objects according to the CSI report configuration when the state of the network side device is switched or at a specific moment, and determine priorities of the at least two target objects, so as to execute a reporting procedure of the at least two objects.

The specific time may be a time agreed by a protocol, a preconfigured time, or a default time of the terminal.

In the embodiment of the application, the priority of the target object is related to the first state of the network side equipment corresponding to the target object; the first state includes any one of: energy-saving state, non-energy-saving state.

It can be understood that, for any one of the at least two target objects, the network side device may determine the priority of the any one target object according to the first state of the network side device corresponding to the any one target object.

It should be noted that, the "the first state of the network side device corresponding to the target object" may be understood as: the network side equipment is in a first state when transmitting the CSI-RS resource set associated with the target object.

The different first states of the network side equipment comprise different energy-saving states and different non-energy-saving states.

Optionally, in the embodiment of the present application, the different energy-saving states are states of using different energy-saving technologies by the network side device, or the different energy-saving states are states with different first features, or the different energy-saving states are states with different second configurations; wherein the first feature comprises at least one of: time domain features, frequency domain features, spatial domain features, and power domain features; the second configuration includes at least one of: time domain configuration, frequency domain configuration, spatial domain configuration, and power domain configuration.

When the first state is the energy-saving state, the terminal may determine energy-saving states (networks ENERGY SAVING, NES) of different Network devices according to different target parameters.

The target parameter may include at least one of: the number of open ports of the network side device, the number of closed ports of the network side device, the number of transmitting and receiving units (TRANSCEIVER UNIT, txRU), the synchronization signal block (Synchronization Signal Block, SSB) period, the measurement time configuration period of SSB (SSB-Measurement Timing Configuration, SSB-MTC) period, the maximum transmit Power of the network side device, the Power spectral density of each per TxRU (Power SpectrumDensity, PSD).

For example, the terminal may determine different NES states according to the number of on ports (or the number of off ports) or TxRU of the network side device.

Also for example, the terminal may determine different NES states according to the SSB period or the SSB-MTC period.

Specific example 1

The terminal may determine different NES states according to the SSB periods, as shown in table 1:

TABLE 1

NES state	SSB cycle
		0	20 Ms
1	40ms
		2	80ms
3	160ms

If the SSB period is 20ms, the terminal may determine that the state of the network side device is NES state 0; if the SSB period is 40ms, the terminal may determine that the state of the network side device is NES state 1; if the SSB period is 80ms, the terminal may determine that the state of the network side device is NES state 2; if the SSB period is 160ms, the terminal may determine that the state of the network side device is bis state 3.

Also for example, the terminal may determine different NES states according to the difference of the maximum transmission powers.

Also for example, the terminal may determine different NES states according to the PSD per TxRU.

Also for example, the terminal may determine different NES states according to different CSI-RS reporting configurations.

Also for example, the terminal may determine different NES states according to different spatial correlation configurations, as shown in table 2:

TABLE 2

For example, if the number of ports is 64 and the power control offset is 3dB, the terminal may determine that the state of the network side device is NES state 1; if the number of ports is 32 and the power control offset is 3dB, the terminal may determine that the state of the network side device is bis state 2; if the number of ports is 32 and the power control offset is 5dB, the terminal may determine that the state of the network side device is bis state 3.

Also for example, the terminal may determine different NES states according to different configurations of all spatial/temporal/frequency/power domains.

Specific example 2

The terminal may determine different NES states according to different CSI-RS reporting configurations (e.g. the number of CSI-RS on ports), as shown in table 3:

TABLE 3 Table 3

NES state	CSI-RS number of ports open
		0	8ports
1	16ports
		2	32ports

If the number of the CSI-RS opening ports is 8ports, the terminal can determine that the state of the network side equipment is NES state0; if the number of the CSI-RS opening ports is 16ports, the terminal can determine that the state of the network side equipment is NES state 1; if the number of the open ports of the CSI-RS is 32ports, the terminal may determine that the state of the network side device is NES state 2.

In the following, three different schemes will be described, specifically illustrating how the terminal determines the priority of at least two target objects.

Scheme one, at least two target objects are at least two target CSI in which different target CSI are generated by measuring different CSI-RS resources (or CSI-RS resource sets).

Optionally, in an embodiment of the present application, the at least two target objects include at least two target CSI. Specifically, as shown in fig. 3 in conjunction with fig. 2, the above step 101 may be specifically implemented by the following step 101 a.

Step 101a, the terminal determines the priority of the first CSI according to the first parameter.

In the embodiment of the present application, the first CSI is any one of at least two target CSI.

It may be understood that the terminal may determine priorities of at least two target CSI according to at least two first parameters, where each first parameter corresponds to one target CSI, and in this embodiment of the present application, any one of the at least two target CSI is described as an example.

Optionally, in the embodiment of the present application, the terminal may determine the priority of the first CSI according to the parameter value of the first parameter.

For example, assuming that the first parameter is 0, the terminal may determine the priority of the first CSI according to a parameter value (i.e., 0) of the first parameter.

In one example, the magnitude of the parameter value of the first parameter may be proportional to the level of priority of the first CSI. For example, the smaller the parameter value of the first parameter, the greater the priority of the first CSI.

In another example, the magnitude of the parameter value of the first parameter may be inversely proportional to the level of priority of the first CSI. For example, the smaller the parameter value of the first parameter, the smaller the priority of the first CSI.

In the embodiment of the present application, the first parameter is related to a first influencing factor associated with the first CSI.

Optionally, in an embodiment of the present application, the first influencing factor includes at least one of the following: the method comprises the steps of a power saving state, a CSI-RS resource set, a CSI-RS resource, a CSI-RS port number, a CSI-RS port muting pattern, a port number of network side equipment and a port muting pattern of the network side equipment, wherein the power saving state, the CSI-RS resource set, the CSI-RS resource, the CSI-RS port number, the CSI-RS port muting pattern are associated with the first CSI.

Optionally, in the embodiment of the present application, the terminal may acquire the first parameter in an explicit manner or an invisible manner.

Wherein the first parameter satisfies at least one of:

Indicated by the network side device;

Is prescribed in advance by a protocol;

And determining by the terminal according to the first rule.

In case the first parameter fulfils the requirements indicated by the network-side device and/or specified in advance by the protocol, it is understood that the terminal obtains the first parameter in an explicit way. In case the first parameter satisfies the first rule determined by the terminal, it is understood that the terminal obtains the first parameter in an invisible manner.

Taking the first parameter satisfaction as an example, which is determined by the terminal according to the first rule:

Optionally, in an embodiment of the present application, the first parameter is determined by the terminal according to a first rule. Specifically, the step 101a may be realized by at least one of the following steps 101a1 to 101a 12.

Step 101a1, the terminal determines a first parameter according to a first energy saving state of the network side device.

Wherein the first energy saving state is: the power saving state associated with the first CSI.

Optionally, in the embodiment of the present application, the terminal may determine a first parameter corresponding to the first energy saving state from the first list. The first list comprises at least two first corresponding relations, and each first corresponding relation is a corresponding relation between one energy-saving state and one parameter. The first list is shown in table 4 below:

TABLE 4 Table 4

	NES state 1	NES state 2	NES state 3	NES state 4	NES state 5
						First parameter x	0	1	2	3	4

For example, assuming that the first energy saving state is NES state4, the terminal may determine the first parameter x (i.e. 3) corresponding to NES state4 directly from Table 4.

Step 101a2, the terminal determines the first parameter according to the second energy saving state of the network side device.

Wherein, the second energy saving state is: the power saving state to be activated by the network device with which the first CSI is associated.

Optionally, in the embodiment of the present application, the terminal may determine a first parameter corresponding to the second energy saving state from the second list. The second list comprises at least two second corresponding relations, and each second corresponding relation is a corresponding relation between one energy-saving state and one parameter.

Optionally, in the embodiment of the present application, in the case that the terminal determines the first parameter according to the second energy saving state, the priority of the first CSI corresponding to the second energy saving state is high.

In an example, assuming that the second energy saving state is 8ports, the terminal may directly determine, from the second list, the first parameter x corresponding to the 8ports, so that the terminal may determine the priority of the first CSI (the priority is a high priority) according to x, and further the terminal may report the first CSI preferentially.

Step 101a3, the terminal determines a first parameter according to the port number of the first CSI-RS resource set.

The first CSI-RS resource set is as follows: a first CSI-RS resource set associated with CSI.

Optionally, in the embodiment of the present application, the number of ports of the first CSI-RS resource set may be the number of open ports or the number of closed ports.

Optionally, in the embodiment of the present application, the terminal may determine, from the third list, a first parameter corresponding to the number of ports of the first CSI-RS resource set. The third list includes at least two third corresponding relations, and each third corresponding relation is a corresponding relation between one port number and one parameter. This third list is shown in table 5 below:

TABLE 5

	8ports	16ports	32ports	64ports
					First parameter x	3	2	1	0

For example, assuming that the number of ports of the first CSI-RS resource set is 8ports, the terminal may determine the first parameter x (i.e., 3) corresponding to 8ports directly from table 5.

Specific example 3

When the state of the network side equipment is switched, the activated periodic P-CSI report contains a plurality of target CSI, the plurality of target CSI are respectively obtained by measuring different CSI-RS resource sets (the different CSI-RS resource sets have different opening port numbers (or closing port numbers)), the priority is judged according to the opening port numbers (or closing port numbers) of the CSI-RS resource sets associated with the plurality of target CSI, the CSI priority corresponding to the CSI-RS sets with more opening port numbers (or closing port numbers) is higher, and the terminal can report the CSI corresponding to the CSI-RS sets with more opening port numbers (or closing port numbers) preferentially.

Step 101a4, the terminal determines a first parameter according to the parameter of the frequency domain occupied by the first CSI-RS resource set.

The parameter of the frequency domain occupied by the first CSI-RS resource set may specifically be the size of the frequency domain occupied by the first CSI-RS resource set.

Optionally, in the embodiment of the present application, the terminal may determine, from the fourth list, a first parameter corresponding to a parameter of the frequency domain occupied by the first CSI-RS resource set. The fourth list includes at least two fourth corresponding relations, and each fourth corresponding relation is a corresponding relation between a parameter of a frequency domain and a parameter.

Optionally, in the embodiment of the present application, when the terminal determines the first parameter according to the parameter of the frequency domain occupied by the first CSI-RS resource set, the larger the size of the frequency domain occupied by the first CSI-RS resource set, the higher the priority of the first CSI corresponding to the first parameter.

Specific example 4

Assuming that the periodic or semi-persistent resource allocation resource set includes multiple CSI-RS resource sets, there may be a problem that there are multiple periodic or semi-persistent CSI reporting conflicts in the same CSI reporting configuration, such as that Physical Uplink SHARED CHANNEL, PUSCH (Physical Uplink SHARED CHANNEL, PUSCH) resources are not fully used. Therefore, the terminal can determine the first parameter according to the parameter of the frequency domain occupied by the first CSI-RS resource set, and the higher the size of the frequency domain occupied by the first CSI-RS resource set is, the higher the priority of the first CSI is.

In the embodiment of the present application, the first rule may be determined in various ways, which will be illustrated below.

Optionally, in an embodiment of the present application, the first rule satisfies any one of the following:

Is agreed by a protocol;

Configured by the network side device.

Optionally, in the embodiment of the present application, in the case that the first rule meets the agreement rule, the agreement rule may specify the corresponding relationship (i.e., at least two first corresponding relationships, at least two second corresponding relationships, at least two third corresponding relationships, at least two fourth corresponding relationships, at least two fifth corresponding relationships, at least two sixth corresponding relationships, and at least two seventh corresponding relationships) in the foregoing embodiment in advance, so as to agree on the first rule.

Optionally, in an embodiment of the present application, the first parameter is determined by the terminal according to a first rule. Specifically, before the step 101, the CSI reporting method provided by the embodiment of the present application may further include the following steps 201 and 202.

Step 201, the terminal receives a first signaling from a network side device.

Optionally, in an embodiment of the present application, the first signaling may include at least one of: downlink Control information (Downlink Control Information, DCI), radio resource Control (Radio Resource Control, RRC), medium access Control (MEDIA ACCESS Control, MAC) Control element (ControlElement, CE).

Step 202, the terminal configures or updates a first rule according to the first signaling.

Optionally, in the embodiment of the present application, the first signaling may include at least one corresponding relationship, so that the terminal may configure or update the corresponding relationship in the foregoing embodiment (i.e., at least two first corresponding relationships, at least two second corresponding relationships, at least two third corresponding relationships, at least two fourth corresponding relationships, at least two fifth corresponding relationships, at least two sixth corresponding relationships, and at least two seventh corresponding relationships) according to the at least one corresponding relationship, so as to configure or update the first rule.

Wherein, when at least one corresponding relation included in the first signaling is used for configuring or updating at least two seventh corresponding relations, any one corresponding relation satisfies at least one of the following:

When the port is closed when the port is silent, a subset of TxRUs which are started when the network side is in an active state before, the CSI priority corresponding to the port silence pattern is lower, and relevant useful information can be obtained from the CSI stored in the previous period.

When the port is silent, txRU which is irrelevant to TxRU corresponding to the sending target signal is closed, the priority of CSI corresponding to the port silence pattern is low, and the target signal does not use the closed TxRU, so that the requirement on the CSI is not urgent.

When the port-quiescing pattern is that any port is not closed, the priority of the first CSI is high according to the first parameter corresponding to the port-quiescing pattern.

In the second scheme, at least two target objects are at least two target CSI reports, and in the at least two target CSI reports, different target CSI reports are associated with different CSI-RS resource sets.

Optionally, in an embodiment of the present application, the at least two target objects include at least two target CSI reports. Specifically, as shown in fig. 4 in conjunction with fig. 2, the above step 101 may be specifically implemented by the following step 101 b.

And step 101b, the terminal calculates and obtains the priority of the first CSI report according to the third parameter and the fourth parameter.

In the embodiment of the present application, the first CSI report is any one of at least two target CSI reports. The third parameter is related to a second influencing factor associated with the first CSI report; the fourth parameter is the number of possible values of the third parameter.

It may be understood that the terminal may calculate the priority of at least two target CSI reports according to at least two third parameters and at least two fourth parameters, where each third parameter corresponds to one target CSI report, and the embodiment of the present application is described by taking any one of the at least two target CSI reports as an example.

Optionally, in an embodiment of the present application, the second influencing factor includes at least one of the following: the energy saving state, the CSI-RS resource set, the CSI-RS resource, the CSI-RS port number, the CSI-RS port muting pattern, the port number of the network side equipment and the port muting pattern of the network side equipment associated with the first CSI report.

Alternatively, in the embodiment of the present application, the above step 101b may be specifically implemented by the following steps 101b1 and 101b 2.

Step 101b1, the terminal adopts a first algorithm, and calculates a target value according to the third parameter and the fourth parameter.

In the embodiment of the present application, the first algorithm is:

Pr_iiCSI(y,k,c,s,z)＝2·N_cells·M_s·Z·y+N_cells·M_s·Z·k+·M_s·Z·c+s·Z+z

Wherein Pri _iCSI is a target value, N _cells is the number of serving cells of the terminal, M _s is the number of CSI report configurations, Z is a third parameter, Z is a fourth parameter, y is a value indicating the type of CSI report, k is a value indicating whether the CSI report carries L1-RSRP, c is the number of serving cells, and s is an Identification (ID) of the CSI report configuration.

Step 101b2, the terminal determines the priority of the first CSI report according to the target value.

In one example, the size of the target value may be proportional to the priority of the first CSI report. For example, the smaller the target value, the greater the priority of the first CSI report.

In another example, the size of the target value may be inversely proportional to the level of priority of the first CSI report. For example, the smaller the target value, the lower the priority of the first CSI report.

Specific example 5

Assuming that the at least two target CSI reports include CSI Report 0 and CSI Report 1, values of s and z in the first algorithm corresponding to CSI Report 0 and CSI Report 1 are shown in table 7:

TABLE 7

	s	z	Z
				CSI Report 0(8ports)	0	3	2
CSI Report 1(64ports)	1	0	2

Thus, by using the first algorithm, the magnitude between the target value for CSI Report 0 and the target value for CSI Report 0 is calculated depends on s·z+z.

Then CSI Report 0 corresponds to s·z+z=0×2+3=3, and CSI Report 0 corresponds to s·z+z=1×2+0=2. I.e. CSI Report 1 has a higher priority, i.e. the decisive influence of the Identity (ID) of the CSI reporting configuration that can be changed after introducing the z-factor on the target CSI Report.

Scheme three, at least two target objects include at least two target CSI and at least two target CSI reports.

Optionally, in an embodiment of the present application, the at least two target objects include at least two target CSI and at least two target CSI reports. Specifically, the above step 101 may be specifically implemented by the following step 101 c.

Optionally, in the embodiment of the present application, the terminal may sort at least two target objects according to the priorities of the at least two target objects; and reporting at least one target object with the forefront sorting, and omitting at least one target object with the last sorting.

According to the CSI reporting method provided by the embodiment of the application, the terminal firstly determines the priority of at least two target objects, wherein the at least two target objects comprise at least two target CSI and/or at least two target CSI reports, the at least two target CSI is the CSI in the same CSI report, or the at least two target CSI is the CSI in the at least two target CSI reports; different target CSI reports are associated with different CSI-RS resource sets; then, according to the priorities of the at least two target objects, executing the reporting flow of the at least two target objects; the priority of the target object is related to a first state of network side equipment corresponding to the target object, and the first state comprises at least one of a power saving state and a non-power saving state. Because the priority of each target object is related to the energy-saving state and/or the non-energy-saving state of the network side equipment corresponding to each target object, when the state of the network side equipment is dynamically changed, the priority of the CSI report is changed along with the change of the state of the network side equipment, so that the CSI related information which is preferentially reported by the terminal can be ensured to be the most needed and latest CSI related information next by the network side equipment, and the network side equipment can directly perform optimal resource scheduling according to the latest CSI related information, thereby improving the communication performance of the terminal.

In the following, it will be specifically illustrated how the terminal performs the reporting procedure of at least two target objects for the three different schemes.

Aiming at scheme one:

Optionally, in an embodiment of the present application, the at least two target objects include at least two target CSI. Specifically, as shown in fig. 5 in conjunction with fig. 2, the above step 102 may be specifically implemented by the following steps 102a and 102 b.

Step 102a, the terminal orders at least two target CSI according to the priority of the at least two target CSI.

Alternatively, in the embodiment of the present application, the above step 102a may be specifically implemented by the following step 102a1 or step 102a 2.

Step 102a1, the terminal sorts each target CSI according to the order of the priorities of at least two target CSI, and sorts the information fields in each target CSI according to the priority of the information fields in each target CSI.

It may be appreciated that the terminal may sort each target CSI as a whole, and then sort the information fields in each sorted target CSI respectively.

Optionally, in an embodiment of the present application, the information field includes any one of the following: channel quality indication (Channel Quantity Indicator, CQI), layer Indication (LI), precoding matrix indication (Precoding Matrix Indicator, PMI), rank Indicator (RI), layer 1 signal-to-interference-and-noise ratio (Layer 1Signal Interference Noise Radio,L1-SINR), layer 1reference signal received power (Layer 1Reference Signal Receive Power,L1-RSRP).

Optionally, in an embodiment of the present application, the priority of the information domain is agreed by a protocol.

Optionally, in the embodiment of the present application, the terminal may sort each target CSI according to the order of priority of at least two target CSI from high to low, and then sort the information fields in each target CSI according to the order of priority of the information fields in each target CSI from high to low.

For example, fig. 6 shows a schematic ordering of at least two target CSI. As shown in fig. 6, at least two target CSI include CSI1, CSI2 and CSI3, where the parameter value of the first parameter x corresponding to CSI1 is 0, i.e. the priority of CSI1 is highest, the parameter value of the first parameter x corresponding to CSI2 is 1, i.e. the priority of CSI2 is next highest, the parameter value of the first parameter x corresponding to CSI3 is 2, i.e. the priority of CSI3 is lowest, the information field of CSI1 includes CQI, LI and PMI, the information field of CSI2 includes CQI, LI and PMI, and the information field of CSI3 includes CQI, LI and PMI; the priority of CQI is higher than that of LI, and the priority of LI is higher than that of PMI. The terminal may sort each CSI according to the order of priority of CSI1, CSI2 and CSI3, where the order of sorted CSI1 is the first, the order of sorted CSI2 is the second, and the order of sorted CSI3 is the third. Then ordering the information domains in the CSI1 according to the priority of the information domains in the CSI1, wherein the sequence of CQI in the ordered CSI1 is the first, the sequence of LI is the second, and the sequence of PMI is the third; ordering the information domains in the CSI2 according to the priority of the information domains in the CSI2, wherein the order of CQI in the ordered CSI2 is the first one, the order of LI is the second one and the order of PMI is the third one; and ordering the information domains in the CSI3 according to the priority of the information domains in the CSI3, wherein the order of CQI in the ordered CSI3 is the first, the order of LI is the second, and the order of PMI is the third.

Therefore, the terminal can sort each target CSI according to the priority of at least two target CSI, and sort the information fields in each target CSI according to the priority of the information fields in each target CSI, that is, the first target CSI in the sorted at least two target CSI is the important target CSI, and the first information field in the important target CSI is the important information field, so that the probability that the terminal omits the important target CSI and the important information field in the important target CSI can be reduced.

102A2, the terminal firstly sorts the first information fields in at least two target CSI according to the priority order of the at least two target CSI; sequencing the second information fields in the at least two target CSI respectively according to the priority order of the at least two target CSI; and sorting the third information fields in the at least two target CSI according to the order of the priorities of the at least two target CSI, and so on until all the information fields in the at least two target CSI are sorted.

In the embodiment of the present application, the priority of the first information domain is higher than the priority of the second information domain, and the priority of the second information domain is higher than the priority of the third information domain.

Optionally, in an embodiment of the present application, the first information field may specifically include any one of the following: CQI, LI, PMI, RI, L1-SINR, L1-RSRP; the second information field may specifically comprise any of the following: CQI, LI, PMI, RI, L1-SINR, L1-RSRP; the third information field may specifically comprise any one of the following: CQI, LI, PMI, RI, L1-SINR, L1-RSRP.

Wherein the first information field, the second information field, and the third information field are all different.

Optionally, in the embodiment of the present application, the terminal sorts the first information fields in at least two target CSI according to the order from high to low of the priority of the at least two target CSI; sequencing the second information fields in the at least two target CSI respectively according to the order from high to low of the priorities of the at least two target CSI; and respectively sequencing the third information fields in the at least two target CSI according to the order from high to low of the priority of the at least two target CSI, and so on until all the information fields in the at least two target CSI are sequenced.

For example, fig. 7 shows a schematic ordering of at least two target CSI. As shown in fig. 7, at least two target CSI include CSI1, CSI2 and CSI3, the parameter value of the first parameter corresponding to CSI1 is 0, i.e. the priority of CSI1 is highest, the parameter value of the first parameter corresponding to CSI2 is 1, i.e. the priority of CSI2 is next highest, the parameter value of the first parameter corresponding to CSI3 is 2, i.e. the priority of CSI3 is lowest, the information field of CSI1 includes a first information field (e.g. CQI), a second information field (e.g. LI) and a third information field (e.g. PMI), the information field of CSI2 includes a first information field (e.g. CQI), a second information field (e.g. LI) and a third information field (e.g. PMI), and the information field of CSI3 includes a first information field (e.g. CQI), a second information field (e.g. LI) and a third information field (e.g. PMI); the priority of CQI is higher than that of LI, and the priority of LI is higher than that of PMI. The terminal may sort the CQIs in CSI1, CSI2, and CSI3 according to the order of the priorities of CSI1, CSI2, and CSI3, respectively, where the order of the CQIs in CSI1 is the first one, the order of the CQIs in CSI2 is the second one, and the order of the CQIs in CSI3 is the third one after the sorting. And then sorting LIs in the CSI1, the CSI2 and the CSI3 according to the priority orders of the CSI1, the CSI2 and the CSI3, wherein the LI in the CSI1 after sorting is fourth in order, the LI in the CSI2 is fifth in order, and the LI in the CSI3 is sixth in order. Finally, sorting PMIs in the CSI1, the CSI2 and the CSI3 according to the priority orders of the CSI1, the CSI2 and the CSI3, wherein the order of the PMIs in the CSI1 after sorting is seventh, the order of the PMIs in the CSI2 is eighth, and the order of the PMIs in the CSI3 is ninth.

As can be seen from this, since the terminal can sort the information fields in the at least two target CSI according to the order of the priorities of the at least two target CSI, that is, the information field that is the first to be sorted in the at least two sorted target CSI is the important information field, the probability that the terminal omits the important information field can be reduced.

Step 102b, the terminal reports the i target CSI with the first rank, and omits j target CSI with the last rank.

In the embodiment of the application, i and j are positive integers.

Aiming at a scheme II:

Optionally, in an embodiment of the present application, the at least two target objects include at least two target CSI reports. Specifically, as shown in fig. 8 in conjunction with fig. 2, the above step 102 may be specifically implemented by the following steps 102c and 102 d.

Step 102c, the terminal orders the at least two target CSI reports according to the priorities of the at least two target CSI reports.

Alternatively, in the embodiment of the present application, the above step 102c may be specifically implemented by the following step 102c1 or step 102c2 or step 102c 3.

102C1, the terminal firstly sorts each target CSI report according to the priority order of at least two target CSI reports; and sequencing the CSI report parts in each target CSI report according to the priority of the CSI report parts in each target CSI report.

It may be appreciated that the terminal may rank each target CSI report as a whole, and then rank CSI report portions in each of the ranked target CSI reports respectively.

Optionally, in an embodiment of the present application, the CSI reporting part includes any of the following: wideband CSI reporting part, subband CSI reporting part. Wherein the subband CSI reporting portion comprises at least one of: an even sub-band portion, an odd sub-band portion; in the ordered CSI report part, the ordering of the even subband part precedes the odd subband part.

It will be appreciated that in this example, in any one CSI report part after ordering, the ordering of the even subband parts is before the odd subband parts.

Optionally, in an embodiment of the present application, the priority of the CSI reporting part is agreed by a protocol.

Optionally, in the embodiment of the present application, the terminal sorts each target CSI report according to the order from high to low of the priorities of at least two target CSI reports; and sequencing the CSI report parts in each target CSI report according to the order from high to low of the priority of the CSI report parts in each target CSI report.

For example, fig. 9 shows a schematic ordering of at least two target CSI reports. As shown in fig. 9, at least two target CSI reports include CSI Report 1 to CSI Report N, the priorities of which CSI Report 1 to CSI Report N decrease, i.e., the priority of CSI Report 1 is highest, the priority of CSI Report 2 is next highest, … …, the priority of CSI Report N is next lowest, the CSI reporting part in CSI Report 1 includes a first CSI reporting part (e.g., wideband CSI reporting part WB CSI Report # 1), a second CSI reporting part (e.g., subband CSI reporting part including even subband part Even SB CSI Report #1 and odd subband part Odd SB CSI Report # 1), the CSI reporting portions in CSI Report 2 include a first CSI reporting portion (e.g., wideband CSI reporting portion WB CSI Report # 2), a second CSI reporting portion (e.g., subband CSI reporting portion including even subband portion Even SB CSI Report #2 and odd subband portion Odd SB CSI Report # 2), … …, and the CSI reporting portion in CSI Report N includes a first CSI reporting portion (e.g., wideband CSI reporting portion WB CSI Report # N), a second CSI reporting portion (e.g., subband CSI reporting portion including even subband portion Even SB CSI Report # N and odd subband portion Odd SB CSI Report # N); the wideband CSI reporting part has a priority greater than that of the subband CSI reporting part, and in any one of the ordered CSI reporting parts, the order of the even subband part precedes the odd subband part. The terminal may sort each target CSI Report according to the order of the priorities of CSI Report 1 to CSI Report N, where the order of CSI Report 1 after sorting is the first, the order of CSI Report 2 is the second, … …, CSI ReportN is the nth. Then sorting the CSI Report parts in each target CSI Report according to the priority of the CSI Report parts in each target CSI Report, wherein the sequence of WB CSI Report #1 in the sorted CSI Report 1 is the first one, the sequence of Even SB CSI Report #1 is the second one, and the sequence of Odd SB CSI Report #1 is the third one; the sequence of WB CSI report#2 in ordered CSI Report 2 is first, the sequence of Even SB CSI Report #2 is second, and the sequence of Odd SB CSI Report #3 is third; … …, the WB CSI Report #n in the ordered CSI Report N is in the first order, even SB CSI Report #n is in the second order, and Odd SB CSI Report #n is in the third order.

As can be seen from this, since the terminal may sort each target CSI report according to the priority of at least two target CSI reports, and sort the CSI report portions in each target CSI report according to the priority of the CSI report portions in each target CSI report, respectively, that is, the most-ordered target CSI report of the at least two sorted target CSI reports is an important target CSI report, and the most-ordered CSI report portion of the important target CSI reports is an important CSI report portion, the probability that the terminal omits the important target CSI report and the important CSI report portion of the important target CSI report can be reduced.

Therefore, the terminal can sort the CSI report parts in the at least two target CSI reports according to the priorities of the at least two target CSI reports, that is, the CSI report part in the front of the at least two sorted target CSI reports is the important CSI report part, so that the probability that the terminal omits the important CSI report part can be reduced.
