[0058] With reference to the accompanying drawings, the information feedback method, receiving method, device, terminal and network-side device provided by the embodiments of the present application are described in detail in terms of some embodiments and application scenarios.

[0059] Please refer to Figure 2 , Figure 2 is a flowchart of an information feedback method provided by the embodiments of the present application, which is executed by a terminal, as shown in Figure 2 , the method comprises the following steps:

[0060] Step 21: The terminal receives a measurement pilot sent by a network-side device.

[0061] In the embodiment, the measurement pilot can be a Channel State Information-Reference Signal (CSI-RS) or the like. The measurement pilot can comprise at least one of the following: a periodic measurement pilot, a semi-persistent measurement pilot, and an aperiodic measurement pilot.

[0062] In some embodiments, the measurement pilot configured by the network-side device for the terminal can be a periodic CSI-RS, or a semi-persistent CSI-RS, or an aperiodic CSI-RS.

[0063] In some embodiments, the base station can configure a measurement pilot for the terminal and send the measurement pilot.

[0064] Step 22: The terminal measures the measurement pilot according to the related parameters of the measurement pilot, and obtains a CSI.

[0065] Step 23: The terminal feeds back the CSI to the network-side device.

[0066] Optionally, the related parameters of the measurement pilot can comprise, but are not limited to, at least one of the following:

[0067] Any one of a measurement window, a number of transmissions, and a measurement length; for example, the measurement window, the number of transmissions, or the measurement length is represented as L, L is an integer greater than 1;

[0068] an oversampling factor; for example, the oversampling factor is represented as O, O is an integer greater than 1;

[0069] a measurement interval; for example, based on the measurement interval, the terminal can measure at every N pilot positions in the measurement window, the number of transmissions, or the measurement length L, N is an integer greater than 1.

[0070] In some embodiments, the terminal can provide CSI feedback at specified time intervals and with appropriate resources.

[0071] The information feedback method of this application embodiment allows a terminal to receive a measurement pilot sent by a network-side device, measure the measurement pilot according to its relevant parameters to obtain the Common Sensor Indicator (CSI), and then feed the CSI back to the network-side device. The relevant parameters of the measurement pilot include at least one of the following: measurement window, number of transmissions, and measurement length; oversampling factor; and measurement interval. Therefore, based on the relevant parameters of the measurement pilot, the terminal can flexibly measure the measurement pilot and thus flexibly feed back the CSI. Furthermore, the CSI flexibly fed back by the terminal can assist the network-side device in efficiently predicting CSI in medium- and high-speed mobile scenarios.

[0072] In this embodiment, based on the relevant parameters of the measured pilot, feedback of Doppler information (such as Doppler information) can be supported. This Doppler information may be, for example, the Doppler information of the terminal's location.

[0073] Optionally, the CSI fed back by the terminal may include first information, which is the quantization information of the Doppler information obtained by the terminal using the vector used for domain transformation. That is, the first information is obtained by the terminal quantizing the Doppler information using the vector used for domain transformation. Here, any one of the measurement window of the measurement pilot, the number of transmissions, and the measurement length, and / or the measurement interval, is used to determine the length of the vector used for domain transformation; the oversampling factor of the measurement pilot is used to characterize the phase rotation of the vector used for domain transformation. Oversampling refers to performing a phase rotation on the corresponding vector. The method of quantizing the Doppler information using the vector used for domain transformation can be set based on actual needs and is not limited thereto. Domain transformation, for example, involves converting the time-domain measurement information of the measurement pilot to the frequency domain to avoid the influence caused by terminal movement, etc.

[0074] In some embodiments, the vector used for domain transformation can be selected as a Discrete Fourier Transform (DFT) vector.

[0075] Optionally, the relevant parameters for measuring the pilot signal can be configured by the network-side device, agreed upon by the protocol, or determined by the terminal and fed back to the network-side device to assist the network-side device in CSI prediction. The above information feedback method may include at least one of the following:

[0076] 1) The terminal receives first configuration information from the network-side device, wherein the first configuration information is used to configure the relevant parameters of the measurement pilot.

[0077] In some embodiments, for the configured periodic measurement pilot, semi-continuous measurement pilot, or aperiodic measurement pilot, the base station may further configure any one of the following for the terminal: measurement window, number of transmissions, and measurement length, and / or configure an oversampling factor, and / or configure a measurement interval.

[0078] 2) The terminal determines the relevant parameters for measuring the pilot signal according to the protocol agreement;

[0079] In some embodiments, for the configured periodic measurement pilot, semi-continuous measurement pilot, or aperiodic measurement pilot, the terminal may determine any one of the measurement window, number of transmissions, and measurement length, and / or determine the oversampling factor, and / or determine the measurement interval, according to the protocol agreement.

[0080] 3) The terminal feeds back the relevant parameters of the measurement pilot to the network-side equipment.

[0081] In some embodiments, if the network-side device does not configure the relevant parameters for the measurement pilot, and / or the protocol does not specify the relevant parameters for the measurement pilot, the terminal can determine the relevant parameters for the measurement pilot based on its own measurement needs / CSI feedback needs and feed them back to the network-side device.

[0082] In other embodiments, if the network-side device has configured the relevant parameters for the measurement pilot, and / or the protocol has agreed upon the relevant parameters for the measurement pilot, but the configured / agreed parameters cannot meet the terminal's measurement requirements / CSI feedback requirements, then the terminal can determine the relevant parameters for the measurement pilot based on its own measurement requirements / CSI feedback requirements and feed them back to the network-side device. For example, taking the measurement length L of the measurement pilot as an example, if the L configured by the base station is too small to meet the terminal's measurement requirements / CSI feedback requirements, then the terminal can determine a larger measurement length L and feed it back to the base station; that is, the feedback measurement length value can be greater than the value configured by the base station.

[0083] In other embodiments, if the network-side device configures multiple values ​​for relevant parameters of a certain measurement pilot, such as the measurement length, the terminal can select one of these multiple values ​​as the actual measured length and feed it back to the network-side device based on its own measurement needs / CSI feedback needs.

[0084] Optionally, to meet the terminal's measurement requirements, the relevant parameters of the measurement pilot can be updated. The terminal can receive control signaling from the network-side equipment, which is used to update the relevant parameters of the measurement pilot. For example, the control signaling may include at least one of the following: Medium Access Control Element (MAC CE), Downlink Control Information (DCI), etc.

[0085] Optionally, when the measurement pilot configured on the network side includes a periodic measurement pilot, the relevant parameters of the periodic measurement pilot may further include: one or more measurement subsets from 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 the measurement window, number of transmissions, and measurement length, and measurement interval.

[0086] For example, if the measurement length L is 8 symbols and the measurement interval N is 4 symbols, then the four configured measurement subsets can be: the first measurement subset {1, 5}, the second measurement subset {2, 6}, the third measurement subset {3, 7}, and the fourth measurement subset {4, 8}.

[0087] In this embodiment, when the measurement pilot configured on the network side includes a semi-persistent measurement pilot, the network-side device sends an activation command and then sends the corresponding activated semi-persistent measurement pilot. Before receiving the measurement pilot sent by the network-side device, the terminal can receive an activation signaling message from the network-side device, which is used to activate the semi-persistent measurement pilot. Afterward, the network-side device can send the activated semi-persistent measurement pilot according to pre-configured parameters. The terminal receives the activated semi-persistent measurement pilot and measures it according to the pre-configured parameters to obtain the CSI and provide feedback.

[0088] Optionally, before receiving activation signaling from the network-side device, the terminal may receive second configuration information from the network-side device; wherein the second configuration information is used to configure at least one semi-persistent measurement pilot for the terminal; and the activation signaling is used to activate one semi-persistent measurement pilot from the configured at least one semi-persistent measurement pilot.

[0089] Optionally, before feeding back CSI to the network-side device, the terminal can receive a deactivation signaling from the network-side device; wherein the deactivation signaling is used to indicate to stop sending semi-persistent measurement pilots and trigger the terminal to feed back CSI.

[0090] In this embodiment, when the measurement pilot configured on the network side includes an aperiodic measurement pilot, the network-side device sends a trigger command and then sends the corresponding triggered aperiodic measurement pilot. Before receiving the measurement pilot sent by the network-side device, the terminal can receive a trigger signaling from the network-side device, wherein the trigger signaling is used to trigger the aperiodic measurement pilot. Afterwards, the network-side device can send the triggered aperiodic measurement pilot according to pre-configured parameters. The terminal receives the triggered semi-persistent measurement pilot and measures it according to the pre-configured parameters to obtain the CSI and provide feedback.

[0091] 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 to configure at least one aperiodic measurement pilot for the terminal; the trigger signaling is used to trigger one aperiodic measurement pilot from the configured at least one aperiodic measurement pilot. Afterwards, after the triggered aperiodic measurement pilot has been sent, the terminal may perform CSI feedback according to a specified time interval and resources.

[0092] Optionally, when the terminal receives an aperiodic measurement pilot, the terminal may feed back the CSI to the network-side device according to a first time interval when feeding back the CSI; wherein, the first time interval is calculated from the time when the terminal receives the last aperiodic measurement pilot sent by the network-side device; the first time interval may include at least one of the following:

[0093] A pre-defined time interval;

[0094] The time interval configured on the network side;

[0095] The time interval indicated by the network side.

[0096] In some embodiments, the terminal can feed back CSI at a predetermined time interval, which is calculated from the time when the terminal receives the last aperiodic measurement pilot sent by the network-side device.

[0097] In other embodiments, the terminal may feed back CSI at a time interval configured on the network side, which is calculated from the time when the terminal receives the last aperiodic measurement pilot sent by the network-side device.

[0098] In some embodiments, the terminal may feed back CSI at a time interval indicated by the network side, which is calculated from the time when the terminal receives the last aperiodic measurement pilot sent by the network-side device.

[0099] Optionally, if the time when the terminal receives the last aperiodic measurement pilot sent by the network-side device does not meet the first time interval requirement with the CSI feedback time, the terminal can measure the aperiodic measurement pilot based on the relevant parameters of the measurement pilot and the transmission time of the aperiodic measurement pilot that meets the CSI feedback time, obtain the CSI, and provide feedback. In this case, the actual measurement window, number of times, or length of the aperiodic measurement pilot... It will be smaller than the configured value. The terminal may or may not provide feedback for the actual measurement. Furthermore, it supplements the DFT vector obtained based on actual measurements of aperiodic pilots. A preset value is set to achieve a vector / sequence length of L for the domain transformation.

[0100] Optionally, when the measurement is performed based on the transmission time of the aperiodic measurement pilot that satisfies the CSI feedback time, the CSI obtained by the terminal may include second information, which is quantized information of the Doppler information obtained by the terminal using a vector for domain transformation, the vector for domain transformation being supplemented by the first vector. The first vector is obtained based on actual measurements of the aperiodic pilot signal, and the preset values ​​are: [values ​​to be filled in]. The length of the vector used for domain transformation is [value to be filled in]. , This indicates the measurement window, number of transmissions, or measurement length of the aperiodic measurement pilot; the length of the first vector is... , This indicates the window, number of measurements, or length of the actual measurement of the non-periodic measurement pilot. The above preset values ​​can be based on pre-set parameters, such as 0, but are not limited to this.

[0101] In some embodiments, when there are L1 actually measured pilots, the first vector is of length L1. The DFT vector.

[0102] In some embodiments, the terminal can Feedback can be sent to the network-side equipment, or it can be omitted. Feedback is sent to the network-side devices.

[0103] Please see Figure 3 , Figure 3 This is a flowchart illustrating an information receiving method provided in an embodiment of this application. The method is executed by a network-side device, such as a base station. Figure 3 As shown, the method includes the following steps:

[0104] Step 31: The network-side device sends a measurement pilot signal to the terminal.

[0105] In this embodiment, the measurement pilot can be selected as CSI-RS, etc. The measurement pilot may include at least one of the following: periodic measurement pilot, semi-continuous measurement pilot, and non-periodic measurement pilot.

[0106] Step 32: The network-side device receives the CSI feedback from the terminal.

[0107] The CSI feedback from the terminal is obtained by measuring the corresponding measurement pilot based on the relevant parameters of the measurement pilot. The relevant parameters of the aforementioned measurement pilot may include, but are not limited to, at least one of the following:

[0108] Any one of the measurement window, the number of transmissions, and the measurement length; for example, the measurement window, the number of transmissions, or the measurement length can be represented as L, where L is an integer greater than 1;

[0109] Oversampling factor; for example, the oversampling factor can be represented as O, where O is an integer greater than 1;

[0110] Measurement interval; for example, based on this measurement interval, the terminal can perform measurements at intervals of N pilot positions within the measurement window, number of transmissions, or measurement length L, where N is an integer greater than 1.

[0111] Therefore, based on the relevant parameters of the measurement pilot, the terminal can flexibly measure the measurement pilot and thus flexibly provide CSI feedback. Furthermore, the CSI feedback flexibly provided by the terminal can assist network-side devices in efficiently predicting CSI in medium- and high-speed mobile scenarios.

[0112] Optionally, the CSI fed back by the terminal may include first information, which is quantization information of Doppler information obtained using the vector used for domain transformation. That is, the first information is obtained by the terminal quantizing the Doppler information using the vector used for domain transformation. Here, any one of the measurement window of the measurement pilot, the number of transmissions, and the measurement length, and / or the measurement interval, is used to determine the length of the vector used for domain transformation; the oversampling factor of the measurement pilot is used to characterize the phase rotation of the vector used for domain transformation. The method of quantizing the Doppler information using the vector used for domain transformation can be set based on actual needs and is not limited thereto.

[0113] Optionally, the relevant parameters for measuring the pilot can be configured by the network-side device, agreed upon by the protocol, or determined by the terminal and fed back to the network-side device to assist the network-side device in CSI prediction. The above information receiving method may include at least one of the following:

[0114] 1) The network-side device sends first configuration information to the terminal; wherein, the first configuration information is used to configure the relevant parameters of the measurement pilot.

[0115] 2) The network-side equipment determines the relevant parameters for measuring the pilot signal according to the protocol.

[0116] 3) The network-side equipment receives the relevant parameters of the measurement pilot from the terminal.

[0117] Optionally, the network-side device can send control signaling to the terminal; this control signaling is used to update relevant parameters of the measurement pilot. For example, the control signaling may include at least one of the following: MAC CE, DCI, etc.

[0118] Optionally, when the measurement pilot configured on the network side includes a periodic measurement pilot, the relevant parameters of the periodic measurement pilot may further include: one or more measurement subsets from 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 the measurement window, number of transmissions, and measurement length, and measurement interval.

[0119] Optionally, when the measurement pilot configured on the network side includes a semi-persistent measurement pilot, before sending the measurement pilot to the terminal, the network-side device may send an activation signaling to the terminal, which is used to activate the semi-persistent measurement pilot.

[0120] Furthermore, before sending the activation signaling to the terminal, the network-side device may send second configuration information to the terminal; wherein, the second configuration information is used to configure at least one semi-persistent measurement pilot 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.

[0121] Furthermore, before receiving the CSI feedback from the terminal, the network-side device can send a deactivation signaling message to the terminal; wherein, the deactivation signaling message is used to indicate the cessation of sending semi-persistent measurement pilots and to trigger the terminal to feed back CSI.

[0122] Optionally, when the network side is configured with an aperiodic measurement pilot, the network side device may send a trigger signaling to the terminal before sending the measurement pilot to the terminal; wherein, the trigger signaling is used to trigger the aperiodic measurement pilot.

[0123] Furthermore, before sending the trigger signaling to the terminal, the network-side device may send third configuration information to the terminal; wherein, the third configuration information is used to configure 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.

[0124] The present application will now be described in conjunction with specific embodiments.

[0125] Example 1

[0126] In this first embodiment, as Figure 4As shown, the base station configures periodic CSI-RS for the terminal and sends periodic CSI-RS. The base station further configures a measurement window or length L=8 for the terminal. The terminal, according to the configuration, measures the CSI-RS at the eight time-domain positions preceding the reference slot when acquiring CSI, and feeds back a CSI report on the given resources. Because L=8, the terminal can use a DFT vector of length 8 to quantize and feed back Doppler information. If the base station further configures an oversampling factor O, for example, equal to 2 (with values ​​of 0 and 1), oversampling refers to phase rotation of the DFT vector. The terminal can also feed back an oversampling factor of "0" or "1" to indicate phase rotation of the DFT vector. If the measurement length L is configured with multiple values, such as 4, 8, 12, etc., the terminal needs to feed back the specific measurement length when acquiring CSI. If the base station further configures a measurement interval, for example, a measurement interval of 2, then when the measurement length L is equal to 8, the terminal can measure the CSI-RS at positions 1, 3, 5, and 7, acquire the CSI, and feed it back. If the terminal feedback measurement interval is, for example, 2, then the actual CSI-RS positions measured by the terminal are position 1, position 3, position 5, and position 7.

[0127] Example 2

[0128] In this second embodiment, as Figure 5 As shown, the base station configures semi-persistent CSI-RS for the terminal and can further configure related parameters of semi-persistent CSI-RS, such as measurement length and measurement interval. The base station activates semi-persistent CSI-RS and transmits the semi-persistent CSI-RS. The terminal performs semi-persistent CSI-RS measurements according to the configuration and acquires CSI.
