In order to facilitate understanding, an application scenario to which the embodiments of the present application are applicable is described below with reference to fig. 1.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. Referring to fig. 1, a network device 101 and one or more terminal devices 102 connected to the network device 101 are included. The terminal device 102 is located within the coverage area of the network device 101. Fig. 1 is only a schematic diagram, and does not constitute a limitation on the applicable scenario of the technical solution provided in the present application.

The network device may send CSI configuration information to the terminal device, where the configuration information includes CSI resource configuration information and CSI report configuration information, where the CSI resource configuration information indicates a subband that needs to be measured by the terminal device, and the CSI report configuration information indicates content of CSI that needs to be reported by the terminal device. The network equipment sends the CSI reference signal on the indicated sub-band, and the terminal equipment measures the CSI reference signal on the indicated sub-band to obtain a plurality of CSI parameters; and generating a CSI report according to the plurality of CSI parameters, and reporting the CSI report to the network equipment. The network device determines a policy for data transmission based on the received CSI report and transmits the data.

The CSI report comprises two parts, namely a first part of CSI and a second part of CSI, wherein the first part of CSI comprises sub-band differential channel quality indicators (channel quality indicator, CQI) of a first transmission block, and the sub-band differential channel quality indicators are arranged in ascending order according to sub-band numbers; the second partial CSI includes a subband differential CQI and precoding matrix indicator (precoding matrix indicator, PMI) subband information field of the second transport block, arranged in order of a subband differential CQI of the even subband set, a PMI subband information field of the even subband set, a subband differential CQI of the odd subband set, and a PMI subband information field of the odd subband set, and the subband differential CQI or PMI subband information fields within the subband set are arranged in ascending subband number order.

Specifically, the first partial CSI includes contents as shown in table 1, and the second partial CSI includes contents as shown in tables 2 and 3.

TABLE 1 first partial CSI

Table 2, wideband parameters in second partial CSI

Table 3 subband parameters in second partial CSI

In a conventional time division duplex (time division duplexing, TDD) system, different time slots are received and transmitted in the same operating wideband, i.e. the entire operating wideband is either upstream or downstream in each time slot.

As shown in fig. 2, the entire operating bandwidth is the downstream bandwidth on slot 0, slot 2 and slot 3, and the entire operating bandwidth is the upstream bandwidth on slot 1, slot 4 and slot 5. The downlink broadband can only be used for transmitting downlink data, and cannot be used for transmitting uplink data; the uplink wideband can only be used to transmit uplink data, but cannot be used to transmit downlink data.

Conventional TDD systems may result in increased traffic scheduling delay compared to frequency division duplex (frequency division duplexing, FDD) systems. In order to overcome the time delay problem brought by the TDD system, a sub-band full duplex mode is introduced, namely, the working broadband is divided into a plurality of sub-bands, and the uplink and downlink proportions of the sub-bands are flexibly configured. Several configurations of sub-band full duplex are shown in fig. 3.

In a full duplex sub-band scene, the network equipment instructs the terminal equipment to measure a preset sub-band and report all the measured CSI. Wherein the preset subband shall be a downlink subband. If the preset sub-band indicated by the network device is dynamically adjusted to be the uplink sub-band, the network device cannot send the CSI reference signal on the preset sub-band, so that the CSI measured by the terminal device on the preset sub-band is inaccurate, and the reported CSI report has lower accuracy.

In order to solve the above technical problems, an embodiment of the present application provides an information reporting method, where only a first CSI parameter of a downlink subband is included in a CSI report reported by a terminal device, or the CSI report includes the first CSI parameter of the downlink subband and a first CSI parameter of an uplink subband set to a preset value. The first CSI parameter of the uplink sub-band with inaccurate measurement is not included in the CSI report, so that the accuracy of the CSI report is improved.

The technical scheme shown in the application will be described below by means of specific examples. It should be noted that the following embodiments may exist independently or may be combined with each other, and for the same or similar content, the description will not be repeated in different embodiments.

Fig. 4 is a flow chart of an information reporting method provided in the embodiment of the present application. Referring to fig. 4, the method may include:

s401, the network equipment sends configuration information to the terminal equipment.

The configuration information may be CSI configuration information including CSI report configuration information and CSI resource configuration information associated with the CSI report configuration information.

The CSI report configuration information may be used to indicate CSI content reported by the terminal device to the network device; the CSI resource configuration information may be used to instruct the network device to send the time-frequency resources of the CSI reference signal to the terminal device.

For example, the network device may indicate to the terminal device, through CSI resource configuration information, a plurality of subbands that need to be measured.

The network device may send at least one CSI configuration information to the terminal device.

The network device may send configuration information to the terminal device through radio resource control (radio resource control, RRC) signaling.

S402, the terminal equipment determines a CSI report according to the configuration information, wherein the CSI report does not comprise the first CSI parameter of the uplink sub-band, or the CSI report comprises a preset value of the first CSI parameter of the uplink sub-band.

The uplink sub-band may be an uplink sub-band of a plurality of sub-bands measured by the network device indication terminal device, where the plurality of sub-bands includes at least one downlink sub-band and at least one uplink sub-band.

In one possible implementation, the terminal device may determine the CSI report by:

determining a plurality of subbands according to the CSI resource allocation information, wherein the plurality of subbands comprise at least one downlink subband and at least one uplink subband; acquiring a second CSI parameter of the network equipment on at least one downlink subband, wherein the second CSI parameter comprises CQI and PMI; generating a first CSI parameter of at least one downlink sub-band according to the CSI report configuration information and at least one second CSI parameter, wherein the first CSI parameter comprises a sub-band differential CQI of a first transmission block, a sub-band differential CQI of a second transmission block and a PMI sub-band information field; and determining the CSI report according to the first CSI parameter of the at least one downlink sub-band.

After receiving the configuration information, the terminal equipment can only determine which sub-bands to measure according to the CSI resource configuration information, and also needs to determine which sub-bands to measure are uplink sub-bands and which sub-bands are downlink sub-bands according to the indication information sent by the network equipment; and the uplink sub-band may be denoted as an invalid sub-band.

The network device may send CSI reference signals on the indicated plurality of subbands, and the terminal device obtains second CSI parameters of the network device on the plurality of subbands by measuring the CSI reference signals on the plurality of subbands.

In the embodiment of the present application, the terminal device may only measure CSI reference signals on downlink subbands in the multiple subbands.

For example, if the subbands indicated by the network device are subband 0, subband 1, subband 2, subband 3, and subband 4, respectively; wherein, subband 0, subband 1, subband 3 and subband 4 are downlink subbands, subband 2 is uplink subband, and the terminal device only needs to measure CSI reference signals carried on subband 0, subband 1, subband 3 and subband 4.

The first transport block may be the first transport block of the physical downlink data channel to which the CSI report corresponds, i.e. the first transport block of the physical downlink data channel scheduled after the network device receives uplink control information (uplink control information, UCI) including the CSI report.

The second transport block may be a second transport block of a physical downlink data channel corresponding to the CSI report, i.e., a second transport block of a physical downlink data channel scheduled after the network device receives UCI including the CSI report.

The sub-band differential CQI is a differential CQI based on the wideband CQI, i.e., a differential value of the sub-band CQI from the wideband CQI.

The network device may determine the sub-band CQI from the wideband CQI and the sub-band differential CQI.

The PMI subband information field may be PM subband information parameter X ₂ 。

And the first CSI parameters of at least one downlink subband are arranged according to the sequence indicated in the CSI report configuration information to obtain a CSI report.

S403, the terminal equipment sends the CSI report to the network equipment.

The terminal device may send CSI reports to the network device via the time-frequency resources indicated by the network device.

In the embodiment shown in fig. 4, the network device sends configuration information to the terminal device; the terminal equipment determines a Channel State Information (CSI) report according to the received configuration information, wherein the CSI report does not comprise the first CSI parameter of the uplink sub-band, or the CSI report comprises a preset value of the first CSI parameter of the uplink sub-band; and send CSI reports to the network device. The terminal equipment improves the accuracy of the CSI report by modifying the report content of the CSI.

In the above embodiments, the content of CSI reports is divided into two cases: one is a first CSI parameter in the CSI report that does not include an uplink subband; another is that the CSI report includes a preset value of the first CSI parameter of the uplink subband. These two cases will be described in detail below.

It should be noted that, the CSI report in the embodiment of the present application also includes the contents of the foregoing tables 1, 2 and 3, but the subband differential CQI of the first transport block in table 1 and the contents of table 3 are changed, and the CSI report mentioned below only describes the part where the contents are changed.

In case one, the CSI report does not include the first CSI parameter of the uplink subband.

In other words, only the first CSI parameter of at least one downlink subband is included in the CSI report. Specifically, the CSI report includes a first partial CSI and a second partial CSI, where the first partial CSI includes a subband differential CQI of a first transport block of at least one downlink subband, and the at least one subband differential CQI is arranged in ascending order according to a number of the at least one downlink subband; the second partial CSI includes a subband differential CQI and PMI subband information field of a second transport block of the at least one downlink subband.

the sub-band differential CQI of the second transport block of the even downlink sub-band, the PMI sub-band information field of the second transport block of the even downlink sub-band, the sub-band differential CQI of the second transport block of the odd downlink sub-band, the PMI sub-band information field of the second transport block of the odd downlink sub-band.

Wherein the even downlink sub-band is a sub-band with even number in at least one downlink sub-band; the odd downlink sub-band is the even numbered sub-band in at least one downlink sub-band; the sub-band differential CQI of the second transmission block of the even number downlink sub-band is arranged according to the ascending sequence of the number of the sub-band; the PMI sub-band information domain of the second transmission block of the even number downlink sub-band is arranged according to the ascending sequence of the number of the sub-band; the sub-band differential CQI of the second transmission block of the odd downlink sub-band is arranged in ascending order according to the number of the sub-band; the PMI sub-band information fields of the second transport block of the odd downlink sub-band are arranged in ascending order according to the number of the sub-band.

The multiple sub-bands corresponding to CSI reports indicated by the network device are arranged from low to high, starting from 0. The number of the downlink sub-band refers to the number of the downlink sub-band among the plurality of sub-bands.

For example, if the network device indicates that the CSI report corresponds to 10 subbands, the subbands are numbered 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9, where subband 7 and subband 8 are uplink subbands and the remaining subbands are downlink subbands.
