Description

[Technical field]

[0001] The present application relates to the field of mobile communications, and in particular to an information reporting method, an information receiving method, an apparatus, a device and a storage medium. [Background technology]

[0002] In mobile communication technology, a terminal feeds back CSI (Channel State Information) to a network device to inform the network device of the channel measurement result of the terminal. When a terminal moves at a medium or high speed, if the period for feeding back CSI from the terminal is too long, the delay of CSI feedback will be long and the accuracy of CSI feedback will be poor. If the period for feeding back CSI is too short, the signaling overhead of CSI feedback will be large. Summary of the Invention [Problem to be solved by the invention]

[0091] Based on the embodiment shown in FIG. 2, the channel state information may be included in the PMI or may exist separately from the PMI.

[0092] In some embodiments, the channel state information is included in the PMI, which means that the channel state information is part of the PMI, and the PMI reported by the terminal includes the above channel state information.

[0093] Optionally, the terminal transmits channel state information corresponding to each beam of the multiple beams to the network device, and it may be understood that the above channel state information is fed back based on each beam separately.

[0100] In addition, when the channel state information in the embodiment of the present application includes at least one coefficient in the above cases, feedback can be performed based on the selected beam and the coefficients related to the above Doppler shift / Doppler extension / Doppler delay / average delay / delay extension.

[0101] In some other embodiments, the channel state information is separate from the PMI, ie, the channel state information is fed back separately from the PMI.

[0102] Optionally, the terminal transmits channel state information corresponding to each beam of the multiple beams to the network device. It may be understood that the above channel state information is fed back based on each beam separately.

[0115] The above embodiments disclose that the terminal reports channel state information, and also reports first information or second information other than the channel state information.

[0116] In some embodiments, after the terminal sends the first information to the network device, if a preset condition is met, the terminal only sends the channel state information to the network device.

[0117] In some other embodiments, after sending the second information to the network device, the terminal only sends the channel state information to the network device if a preset condition is met.

[0118] Here, the preset condition indicates that after the terminal transmits the first information or the second information, it does not need to retransmit the first information or the second information.

[0119] In some embodiments, the preset condition is: (1) At least one of CRI and RI does not change; and (2) The time to transmit at least one of the CRI, PMI, RI, CQI, and LI has not yet arrived.

[0120] In an embodiment of the present application, if the terminal has already transmitted at least one of the CRI, PMI, RI, CQI, and LI and the channel state information, i.e., the channel state information exists separately from the PMI, and it has not yet reached the time to transmit the next CRI, PMI, RI, CQI, and / or LI, then there is no need to retransmit at least one of the CRI, PMI, RI, CQI, and / or LI, and it is sufficient to only transmit the channel state information.

[0121] Alternatively, if the terminal has already transmitted at least one of the CRI, PMI, RI, CQI, and LI and the channel state information, i.e., the channel state information exists separately from the PMI, and at least one of the CRI and RI does not change in the next report, there is no need to retransmit at least one of the CRI, PMI, RI, CQI, and LI, and it is sufficient to only transmit the channel state information.

[0122] Alternatively, if the terminal has already transmitted at least one of the CRI, RI, CQI, and LI, and the PMI including the channel state information, but the time to transmit the next CRI, RI, CQI, and / or LI has not yet arrived, there is no need to retransmit at least one of the CRI, RI, CQI, and / or LI, and it is sufficient to only transmit the channel state information.

[0123] Alternatively, if the terminal has already transmitted at least one of the CRI, RI, CQI, and LI, and a PMI including the channel state information, but at least one of the CRI and RI does not change in the next report, there is no need to retransmit at least one of the CRI, RI, CQI, and LI, and it is sufficient to only transmit the PMI including the channel state information.

[0124] In the method provided by the embodiment of the present application, the terminal only needs to transmit the channel state information when a preset condition is met, and does not need to retransmit other information than the channel state information, thereby saving signaling overhead.

[0125] It should be noted that the above embodiments may be divided into new embodiments or may be combined with other embodiments to form new embodiments, and the present application does not limit the combination between the embodiments.
