[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.

[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 feed back the CSI according to a specified time interval and resource.

[0071] In the information feedback method of the embodiments, the terminal can receive a measurement pilot sent by the network side device, measure the measurement pilot according to a related parameter of the measurement pilot, obtain the CSI, and feed back the CSI to the network side device. The related parameter of the measurement pilot includes at least one of the following: any one of a measurement window, a sending times, and a measurement length; an oversampling factor; and a measurement interval. In this way, based on the related parameter of the measurement pilot, the terminal can flexibly measure the measurement pilot, thereby flexibly feeding back the CSI. Further, through the CSI flexibly fed back by the terminal, the network side device can be assisted to efficiently predict the CSI in a high-speed mobile scenario.

[0072] In the embodiments, based on the related parameter of the measurement pilot, feedback of Doppler information (such as Doppler information) can be supported. The Doppler information is, for example, Doppler information of a location to which the terminal belongs.

[0073] Optionally, the CSI fed back by the terminal can include first information, which is quantized information of the Doppler information obtained by the terminal using a vector for domain transformation, that is, the first information is obtained by the terminal by quantizing the Doppler information using the vector for domain transformation. Any one of the measurement window, the sending times, and the measurement length of the measurement pilot and / or the measurement interval are used to determine the length of the vector for domain transformation; and the oversampling factor of the measurement pilot is used to represent the phase rotation of the vector for domain transformation. The oversampling refers to phase rotation of the corresponding vector. As to the manner of quantizing the Doppler information using the vector for domain transformation, it can be set based on actual needs, and no limitation is made thereto. The domain transformation is, for example, conversion of time domain measurement information of the measurement pilot to a frequency domain, so as to avoid the influence caused by terminal movement and the like.

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

[0075] Optionally, as to the related parameter of the measurement pilot, it can be configured by the network side device, can be agreed by a protocol, or can be determined by the terminal and fed back to the network side device, so as to assist the network side device to predict the CSI. The above information feedback method can 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 related parameter of the measurement pilot.

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

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

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

[0082] In other embodiments, if the network side device has configured the relevant parameters of the measurement pilot, and / or the protocol has stipulated the relevant parameters of the measurement pilot, but the configured / stipulated relevant parameters of the measurement pilot cannot meet the terminal's measurement requirement / feedback CSI requirement, the terminal can determine the relevant parameters of the measurement pilot based on its own measurement requirement / feedback CSI requirement and feed back to the network side device. For example, taking the measurement length L of the measurement pilot as an example, if the base station configures a smaller L that cannot meet the terminal's measurement requirement / feedback CSI requirement, the terminal can determine a larger measurement length L and feed back to the base station, i.e., the fed back measurement length value can be larger than the configured value by the base station.

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

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

[0085] Optionally, when the measurement pilot configured by the network side comprises a periodic measurement pilot, the related parameters of the periodic measurement pilot further comprise: one or more measurement subsets in N measurement subsets; wherein, the N is an integer greater than 1, and the N measurement subsets are determined based on any one of the following related parameters of the measurement pilot: measurement window, transmission times, 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, the 4 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 the embodiments of the present application, when the measurement pilot configured by the network side comprises a semi-persistent measurement pilot, after the network side device sends an activate command, the corresponding activated semi-persistent measurement pilot is sent. Before the above-mentioned receiving the measurement pilot sent by the network side device, the terminal can receive an activation signaling from the network side device, wherein the activation signaling is used to activate the semi-persistent measurement pilot. Then, the network side device can send the activated semi-persistent measurement pilot according to the related parameters configured in advance, the terminal receives the activated semi-persistent measurement pilot, and measures the activated semi-persistent measurement pilot according to the related parameters configured in advance, obtains the CSI and feeds back.

[0088] Optionally, before receiving the activation signaling from the network side device, the terminal can 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 the CSI to the network side device, the terminal can receive a deactivate signaling from the network side device; wherein, the deactivate signaling is used to instruct to stop sending the semi-persistent measurement pilot, and trigger the terminal to feed back the CSI.

[0090] In the embodiments of the present application, when the measurement pilot configured by the network side comprises a non-periodic measurement pilot, after the network side device sends a trigger command, the corresponding triggered non-periodic measurement pilot is sent. Before the above-mentioned 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 non-periodic measurement pilot. Then, the network side device can send the triggered non-periodic measurement pilot according to the related parameters configured in advance, the terminal receives the triggered semi-persistent measurement pilot, and measures the triggered non-periodic measurement pilot according to the related parameters configured in advance, obtains the CSI and feeds back.

[0091] Optionally, before receiving the triggering signaling from the network side device, the terminal can 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 triggering signaling is used to trigger one aperiodic measurement pilot from the configured at least one aperiodic measurement pilot. After the triggered aperiodic measurement pilot is transmitted, the terminal can perform CSI feedback according to the specified time interval and resource.

[0092] Optionally, in the case that the terminal receives the aperiodic measurement pilot, the terminal can perform CSI feedback 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 transmitted by the network side device; the first time interval can include at least one of the following:

[0093] a pre-specified time interval;

[0094] a network side configured time interval;

[0095] a network side indicated time interval.

[0096] In some embodiments, the terminal can perform CSI feedback according to a pre-specified time interval, which is calculated from the time when the terminal receives the last aperiodic measurement pilot transmitted by the network side device.

[0097] In some other embodiments, the terminal can perform CSI feedback according to a network side configured time interval, which is calculated from the time when the terminal receives the last aperiodic measurement pilot transmitted by the network side device.

[0098] In some embodiments, the terminal can perform CSI feedback according to a network side indicated time interval, which is calculated from the time when the terminal receives the last aperiodic measurement pilot transmitted by the network side device.

[0099] Optionally, if the time when the terminal receives the last aperiodic measurement pilot transmitted by the network side device and the CSI feedback time do not satisfy the requirement of the first time interval, the terminal can perform measurement on the aperiodic measurement pilot according to the related parameters of the measurement pilot and the transmission time of the aperiodic measurement pilot satisfying the CSI feedback time, obtain the CSI and perform feedback. In this case, the actual measurement window, number or length L1 of the aperiodic measurement pilot will be smaller than the configured L, and the terminal can or can not feedback the L1 used for actual measurement, and supplement L-L1 preset values to the DFT vector obtained based on the actual measurement on the aperiodic measurement pilot to make the length of the domain transformed vector / sequence L.

The preset value can be based on pre-setting, such as 0, but not limited thereto.

[0101] In some embodiments, in the case of L1 actual measurement pilots, the first vector is a DFT vector with a length of L1.

[0102] In some embodiments, the terminal can feed back L1 to the network side device, or can not feed back L1 to the network side device.

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

[0125] Embodiment One

[0126] In the present embodiment one, 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 quantize and feed back Doppler information using a DFT vector of length 8. 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.

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=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 the 1st position, the 3rd position, the 5th position, and the 7th position.
