The information feedback method, the receiving method, the device, the terminal and the network side device provided by the embodiment of the application are described in detail through some embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of an information feedback method provided in an embodiment of the present application, where the method is performed by a terminal, and as shown in fig. 2, the method includes the following steps:

step 21: and the terminal receives the measurement pilot frequency sent by the network side equipment.

In this embodiment, the measurement pilot may be a channel state information Reference Signal (CSI-RS) or the like. The measurement pilot may include at least one of: periodic (Periodic) measurement pilot, semi-persistent (semi-persistent) measurement pilot, and aperiodic (aperiodic) measurement pilot.

In some embodiments, the measurement pilot configured by the network side device for the terminal may be selected from a periodic CSI-RS, a semi-persistent CSI-RS, or an adaptive CSI-RS.

In some embodiments, the base station may configure the measurement pilot for the terminal and transmit the measurement pilot.

Step 22: and the terminal measures the measurement pilot frequency according to the related parameters of the measurement pilot frequency to obtain the CSI.

Step 23: and the terminal feeds back the CSI to the network side equipment.

Optionally, the relevant parameters of the measurement pilot may include, but are not limited to, at least one of the following:

any one of a measurement window, a number of transmissions, and a measurement length (Measurement Length); for example, the measurement window, the number of transmissions, or the measurement length is denoted as L, which is an integer greater than 1;

an oversampling factor; for example, the oversampling factor is represented as O, O being an integer greater than 1;

measuring the interval; for example, based on the measurement interval, the terminal may perform measurement at N pilot positions in a measurement window, a number of transmissions, or a measurement length L, where N is an integer greater than 1.

In some embodiments, the terminal may perform CSI feedback at a specified time interval and on the resources.

According to the information feedback method, a terminal can receive measurement pilot frequency sent by network side equipment, measure the measurement pilot frequency according to relevant parameters of the measurement pilot frequency, obtain CSI, and feed back the CSI to the network side equipment; the relevant parameters of the measurement pilot include at least one of the following: any one of a measurement window, a number of transmissions, and a measurement length; an oversampling factor; the interval is measured. Therefore, based on the related parameters of the measurement pilot frequency, the terminal can flexibly measure the measurement pilot frequency, so that the CSI is flexibly fed back. Furthermore, through the CSI flexibly fed back by the terminal, the network side equipment can be assisted to efficiently conduct CSI prediction in a medium-high speed moving scene.

In the embodiment of the application, based on the relevant parameters of the measurement pilot frequency, feedback of Doppler information (such as Doppler information) can be supported. The doppler information is, for example, the doppler information of the location to which the terminal belongs.

Alternatively, the CSI fed back by the terminal may include first information, where the first information is quantized information of doppler information acquired by the terminal using a vector for domain transformation, that is, the first information is quantized by the terminal using a vector for domain transformation. Wherein any one of a measurement window, a number of transmissions, and a measurement length of the measurement pilot and/or a measurement interval is used to determine a length of a vector for domain transformation; the oversampling factor of the measurement pilot is used to characterize the phase rotation of the vector used for the domain transformation, oversampling being the phase rotation of the corresponding vector. The manner of quantizing the doppler information using the vector for domain transformation may be set based on actual requirements, and is not limited thereto. The domain transformation is, for example, to convert the time domain measurement information of the measurement pilot into the frequency domain, so as to avoid the influence caused by the movement of the terminal, etc.

In some embodiments, the vector for domain transformation described above may be selected as a discrete fourier transform (Discrete Fourier Transform, DFT) vector.

Optionally, for the relevant parameters of the measurement pilot frequency, the relevant parameters can be configured by the network side equipment, can be agreed by a protocol, or can be fed back to the network side equipment after being determined by the terminal so as to assist the network side equipment in carrying out the CSI prediction. The information feedback method may include at least one of:

1) The terminal receives first configuration information from the network side equipment, wherein the first configuration information is used for configuring relevant parameters of the measurement pilot frequency.

In some embodiments, the base station may further configure any of a measurement window, a number of transmissions, and a measurement length for the terminal, and/or configure an oversampling factor, and/or configure a measurement interval for configured periodic measurement pilots, semi-persistent measurement pilots, or non-periodic measurement pilots.

2) The terminal determines relevant parameters of the measurement pilot frequency according to protocol convention;

in some embodiments, for configured periodic, semi-persistent, or aperiodic measurement pilots, the terminal can determine any of a measurement window, a number of transmissions, and a measurement length, and/or an oversampling factor, and/or a measurement interval, in accordance with a protocol convention.

3) The terminal feeds back the relevant parameters of the measurement pilot frequency to the network side equipment.

In some embodiments, if the network side device does not configure the relevant parameters of the measurement pilot, and/or the protocol does not agree on the relevant parameters of the measurement pilot, the terminal may determine the relevant parameters of the measurement pilot and feed back the parameters to the network side device based on its measurement requirement/requirement of feedback CSI.

In other embodiments, if the network side device has configured the relevant parameters of the measurement pilot and/or the protocol has agreed the relevant parameters of the measurement pilot, but the configured/agreed relevant parameters of the measurement pilot cannot meet the requirement of the terminal for measurement/feedback CSI, the terminal may determine the relevant parameters of the measurement pilot and feed back to the network side device based on the requirement of the terminal for measurement/feedback CSI. For example, taking the measurement length L of the measurement pilot frequency as an example, if L configured by the base station is smaller and cannot meet the measurement requirement of the terminal/the requirement of feeding back CSI, the terminal may determine a larger measurement length L and feed back the measurement length L to the base station, that is, the value of the fed back measurement length may be greater than the value configured by the base station.

In other embodiments, if the network side device configures a plurality of values for a relevant parameter of a certain measurement pilot, such as a measurement length, the terminal may select one value from the plurality of values as an actual measured length and feed back to the network side device based on its measurement requirement/requirement for feeding back CSI.

Optionally, in order to meet the measurement requirements of the terminal, the relevant parameters of the measurement pilot may be updated. The terminal may receive control signaling from the network-side device, the control signaling being used to update relevant parameters of the measurement pilot. For example, the control signaling may include at least one of: media access control units (Medium Access Control Control Element, MAC CE), downlink control information (Downlink Control Information, DCI), etc.

Optionally, when the measurement pilot configured at the network side includes a periodic measurement pilot, the relevant parameters of the periodic measurement pilot may further include: one or more of the N measurement subsets; wherein N is an integer greater than 1, and the N measurement subsets are determined based on the following relevant parameters of the measurement pilot: any one of a measurement window, a number of transmissions, and a measurement length, and a measurement interval.

For example, if the measurement length L is 8 symbols and the measurement interval N is 4 symbols, the configured 4 measurement subsets may be respectively: a first subset of measurements {1,5}, a second subset of measurements {2,6}, a third subset of measurements {3,7}, a fourth subset of measurements {4,8}.

In this embodiment, when the measurement pilot configured by the network side includes a semi-persistent measurement pilot, after sending an activate command, the network side device sends the corresponding activated semi-persistent measurement pilot. Before receiving the measurement pilot sent by the network side device, the terminal may receive an activation signaling from the network side device, where the activation signaling is used to activate the semi-persistent measurement pilot. And then, the network side equipment can send the activated semi-continuous measurement pilot frequency according to the related parameters configured in advance, the terminal receives the activated semi-continuous measurement pilot frequency, and measures the activated semi-continuous measurement pilot frequency according to the related parameters configured in advance to obtain the CSI and feed back the CSI.

Optionally, before receiving the activation signaling from the network side device, the terminal may receive second configuration information from the network side device; the second configuration information is used for configuring at least one semi-continuous measurement pilot frequency for the terminal; the activation signaling is used to activate one semi-persistent measurement pilot from the configured at least one semi-persistent measurement pilot.

Optionally, before feeding back CSI to the network side device, the terminal may receive a deactivation (deactivation) signaling from the network side device; the deactivation signaling is used for indicating to stop sending the semi-continuous measurement pilot frequency and triggering the terminal to feed back the CSI.

In this embodiment, when the measurement pilot configured by the network side includes an aperiodic measurement pilot, after sending a trigger (trigger) command, the network side device sends the aperiodic measurement pilot that is triggered correspondingly. Before receiving the measurement pilot frequency sent by the network side device, the terminal may receive a trigger signaling from the network side device, where the trigger signaling is used to trigger the aperiodic measurement pilot frequency. And then, the network side equipment can send the triggered aperiodic measurement pilot frequency according to the related parameters configured in advance, the terminal receives the triggered semi-continuous measurement pilot frequency, and measures the triggered aperiodic measurement pilot frequency according to the related parameters configured in advance to obtain the CSI and feed back the CSI.

Optionally, before receiving the trigger signaling from the network side device, the terminal may receive third configuration information from the network side device; wherein the third configuration information is used for configuring at least one aperiodic measurement pilot for the terminal; the trigger signaling is used to trigger an aperiodic measurement pilot from the configured at least one aperiodic measurement pilot. After the triggered aperiodic measurement pilot frequency is sent, the terminal can perform CSI feedback according to the specified time interval and the resources.

Optionally, when the terminal receives the aperiodic measurement pilot, the terminal may feed back CSI to the network side device according to the first time interval when feeding back CSI; the first time interval is calculated from the time when the terminal receives the last non-periodic measurement pilot frequency sent by the network side equipment; the first time interval may comprise at least one of:

a predetermined time interval;

a time interval configured by a network side;

time intervals indicated by the network side.

In some embodiments, the terminal may feed back CSI at a predetermined time interval, where the predetermined time interval is calculated from the time when the terminal receives the last aperiodic measurement pilot sent by the network-side device.

In other embodiments, the terminal may feed back CSI according to a time interval configured by the network side, where the time interval configured by the network side is calculated from the time when the terminal receives the last aperiodic measurement pilot sent by the network side device.

In some embodiments, the terminal may feed back CSI at a time interval indicated by the network side, where the time interval indicated by the network side is calculated from the time when the terminal received the last aperiodic measurement pilot sent by the network side device.

Optionally, if the time of the terminal receiving the last aperiodic measurement pilot frequency sent by the network side device and the feedback time of the CSI do not meet the requirement of the first time interval, the terminal may measure the aperiodic measurement pilot frequency according to the relevant parameters of the measurement pilot frequency and the sending time of the aperiodic measurement pilot frequency that meets the feedback time of the CSI, so as to obtain the CSI and feed back the CSI. In this case, the window, the number of times, or the length L1 of the actual measurement of the aperiodic measurement pilot may be smaller than the configured L, and the terminal may or may not feedback the L1 for the actual measurement and supplement the DFT vector obtained based on the actual measurement of the aperiodic measurement pilot by L-L1 preset values to achieve the length L of the vector/sequence of the domain transform.

Alternatively, in case of performing measurement according to a transmission time of the aperiodic measurement pilot satisfying the CSI feedback time, the CSI obtained by the terminal may include second information, which is quantized information of doppler information obtained by the terminal using a vector for domain transformation obtained by supplementing a first vector obtained based on actual measurement of the aperiodic measurement pilot with L-L1 preset values. The length of the vector used for domain transformation is L, wherein L represents the measurement window, the transmission times or the measurement length of the aperiodic measurement pilot frequency; the length of the first vector is L1, L1 representing the window, number of times or length of actual measurements of the aperiodic measurement pilot. The preset value may be preset, for example, may be selected to be 0, but is not limited thereto.

In some embodiments, in the case of L1 actually measured pilots, the first vector is a DFT vector of length L1.

In some embodiments, the terminal may or may not feed back L1 to the network side device.

Therefore, based on the related parameters of the measurement pilot frequency, the terminal can flexibly measure the measurement pilot frequency, so that the CSI is flexibly fed back. Furthermore, through the CSI flexibly fed back by the terminal, the network side equipment can be assisted to efficiently conduct CSI prediction in a medium-high speed moving scene.

Alternatively, the CSI fed back by the terminal may include first information, which is quantization information of the doppler information obtained by using the vector for domain transformation, that is, the first information is obtained by quantizing the doppler information by the terminal using the vector for domain transformation. Wherein any one of a measurement window, a number of transmissions, and a measurement length of the measurement pilot and/or a measurement interval is used to determine a length of a vector for domain transformation; the oversampling factor of the measurement pilot is used to characterize the phase rotation of the vector for domain transformation.

The base station further configures a measurement window or length l=8 for the terminal, and the terminal performs measurement according to CSI-RS configured according to 8 time domain positions before a reference slot (reference slot) when acquiring CSI, and feeds back CSI reports on a given resource. Because l=8, the terminal can perform quantization feedback on Doppler information using a DFT vector of length 8. If the base station is further configured with an oversampling factor O, such as equal to 2 (values 0 and 1), the oversampling means that the DFT vector is phase rotated, then the terminal may also feed back the oversampling factor of "0" or "1" to indicate the phase rotation of the DFT vector. If the measurement length L is configured with a plurality of values, such as values of 4, 8, 12, etc., the terminal needs to feed back the specific measurement length when acquiring CSI. If the base station is further configured with a measurement interval, for example, the measurement interval is 2, the terminal may measure CSI-RS of the 1 st, 3 rd, 5 th and 7 th positions in case that the measurement length L is equal to 8, acquire CSI and feed back. If the terminal feedback measurement interval is, for example, 2, the CSI-RS positions actually measured by the terminal are the 1 st position, the 3 rd position, the 5 th position, and the 7 th position.

Example two

In the second embodiment, as shown in fig. 5, the base station configures a semi-persistent CSI-RS for the terminal, and may further configure relevant parameters of the semi-persistent CSI-RS, such as a measurement length, a measurement interval, and the like. The base station activates the semi-persistent CSI-RS and transmits the semi-persistent CSI-RS. And the terminal measures the semi-persistent CSI-RS according to the configuration and acquires the CSI. The base station may deactivate the semi-persistent CSI-RS and trigger the terminal to send CSI, which the terminal sends CSI reports on the designated resources.

In addition, when the terminal feeds back the CSI report, the CSI report may also be sent on the designated resource in a similar manner to the periodic CSI-RS after the base station activates the semi-persistent CSI-RS and before the base station deactivates the semi-persistent CSI-RS.
