And (3) collision group: and a set of colliding CSI reports on the same CC, wherein any one CSI report of a colliding group collides with at least one CSI report in the colliding group, and does not collide with any CSI report outside the colliding group.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flow chart of a method for transmitting CSI reports according to an embodiment of the present invention. The method of fig. 1 is applicable to a terminal device. The method comprises the following steps:

and S110, processing the CSI reports which are collided based on the priority of the CSI reports in the CSI reports which need to be transmitted on the PUCCH resources of the component carriers.

The number of the collided CSI reports is more than two, and the processing comprises a reservation processing and a discarding processing.

It should be understood that one CSI report is allocated to use one PUCCH resource of the component carrier. The PUCCH resources, component carriers used by CSI reporting may be allocated by a network device (e.g., a base station, etc.).

It should be understood that the reservation process, i.e., CSI report determination transmission; discard processing, i.e. CSI report determination, not sent.

It should be understood that, in the embodiment of the present invention, the collided CSI report is processed, so that there is no collided CSI report for the current component carrier after the processing. Or, after the CSI report with the collision is processed, the CSI report with the collision does not exist in the current component carrier. And if the CSI reports which are collided still exist after one-time discarding processing, continuing discarding processing based on the priority of the CSI reports.

It should be understood that, in the embodiment of the present invention, the priority of the CSI report may follow the priority specification of discarding when the CSI report collides in the prior art. Specifically, each CSI report corresponds to a priority value, and the UE does not send some CSI reports with high (or low) priority values when CSI reports collide or uplink transmission resources are limited. For example: the CSI priority is first determined according to rule 1, if the priorities obtained according to rule 1 are equal, then determined according to rule 2, and so on.

Rule 1: determining the priority according to the time domain behaviors/the channel types, wherein the priority sequence is as follows: SP-CSI on AP-CSI > PUSCH > SP-CSI on PUCCH > P-CSI;

rule 2: determining the priority according to the CSI content, wherein the priority order is as follows: beam reports (Beam reports) > CSI;

rule 3: determining the priority according to the CellID, wherein the priority order is as follows: other cell IDs in ascending order for primary cell (PCell) > PSCell >;

rule 4: determining the priority according to the CSI report ID, wherein the priority sequence is as follows: in ascending order of CSI reportids.

Wherein, the rules 2-4 are only applicable to AP-CSI and SP-CSI transmitted based on PUCCH.

Of course, scenarios in which the method of the embodiment of the present invention employs other priority rules are not excluded, and the embodiment of the present invention is not limited herein.

And S120, transmitting the corresponding CSI report on the PUCCH resource used by the CSI report reserved in the current component carrier.

In the embodiment of the invention, more than two collided CSI reports on the PUCCH resources of the component carrier are processed based on the priority of the CSI reports, so that the problem of competition of the CSI reports on the PUCCH resources of the component carrier is solved.

Optionally, in some embodiments, step S110 may be specifically implemented as: in each collision group in the collided CSI reports, processing the CSI reports in the collision group respectively based on the priority of the CSI reports in the collision group, wherein the collided CSI reports comprise a plurality of collision groups, one collision group comprises at least two CSI reports, and any one CSI report in the collision group collides with at least one CSI report in the collision group and does not collide with the CSI reports outside the collision group;

wherein, step S120 may be specifically implemented as: and transmitting the corresponding CSI report on the PUCCH resource used by the CSI report reserved in each collision group in the current component carrier.

It should be understood that any CSI report in the collision group collides with at least one CSI report in the collision group, and does not collide with CSI reports outside the collision group, for example, if the first CSI report is any CSI report of the collision group, the first CSI report collides with at least one CSI report in the collision group. Furthermore, if there is a CSI report outside the collision group, the first CSI report does not collide with any CSI report outside the collision group.

Further, in some embodiments, when the CSI reports in the collision group are processed based on the priority of the CSI reports in the collision group, CSI reports with low priority may be discarded one by one until there is no colliding CSI report in the collision group.

Fig. 2 is a schematic diagram of a scenario where CSI reports transmitted through PUCCH resources on the same CC collide according to an embodiment of the present invention. As shown in fig. 2, one rectangular box represents PUCCH resources occupied by one CSI report, 1,2, 3, 4, 5 represent PUCCH-based CSI reports 1,2, 3, 4, 5, respectively, and 1 represents highest priority, and so on. The horizontal axis is time and the vertical axis is frequency. It should be understood that the colliding PUCCHs do not necessarily overlap in the frequency domain. In fig. 2, CSI report 1, CSI report 2, and CSI report 3 collide, CSI report 4 and CSI report 5 collide, and { CSI report 1, CSI report 2, CSI report 3} does not collide with { CSI report 4, CSI report 5 }. According to the definition of collision groups, { CSI report 1, CSI report 2, CSI report 3} is one collision group, and { CSI report 4, CSI report 5} is another collision group. Based on fig. 2, the following table can be obtained:

table 1:

in the application scenario shown in fig. 2, in the collision set { CSI report 1, CSI report 2, CSI report 3}, CSI report 3 is discarded, CSI report 2 is discarded, and CSI report 1 is retained; in collision set { CSI report 4, CSI report 5}, CSI report 5 is discarded and CSI report 4 is retained. At this time, the CSI reports that need to be transmitted are CSI report 1 and CSI report 4.

Fig. 3 is a schematic diagram of a scenario where CSI reports transmitted through PUCCH resources on the same CC collide according to an embodiment of the present invention. As shown in FIG. 3, the overlap relationship can be represented by Table 2:

table 2:

in the application scenario shown in fig. 3, the collision set { CSI report 1, CSI report 2, CSI report 3} may discard CSI report 3 first; collision set { CSI report 4, CSI report 5} discards CSI report 5 first. At this time, the CSI reports that need to be transmitted are CSI report 1, CSI report 2, and CSI report 4.

Further, in some embodiments, the step S110 may be further implemented as:

in each collision group, based on the priority of the CSI reports in the collision group, reserving the CSI report with the highest priority in the collision group, and discarding the rest CSI reports in the collision group.

Or the application scenarios of fig. 2 and 3.

In the application scenario shown in fig. 2, collision set { CSI report 1, CSI report 2, CSI report 3} may discard CSI report 3 and CSI report 2; collision set { CSI report 4, CSI report 5} discards CSI report 5. At this time, the CSI reports that need to be transmitted are CSI report 1 and CSI report 4.

In the embodiment shown in fig. 3, collision set { CSI report 1, CSI report 2, CSI report 3} may be to discard CSI report 3 and CSI report 2; collision set { CSI report 4, CSI report 5} to discard CSI report 5. At this time, the CSI reports that need to be transmitted are CSI report 1 and CSI report 4.

Or, further, in some embodiments, the step S110 may be further implemented specifically as: and processing the CSI reports in the CSI report set based on the priority of the CSI reports in the CSI report set and the time sequence occupied by PUCCH resources for transmitting the CSI reports, wherein the CSI report set is the set of the CSI reports of the collision group.

Optionally, in some embodiments, step S110 may be specifically implemented as:

processing the CSI reports in the CSI report set based on the priority of the CSI reports in the CSI report set and the time sequence occupied by PUCCH resources for transmitting the CSI reports;

the CSI report set is the set of the collided CSI reports, or the CSI report set is the set of all CSI reports that need to be transmitted on the PUCCH resource of the component carrier.

Specifically, in some embodiments, processing the CSI reports in the CSI report set based on the priority of the CSI reports in the CSI report set and the time sequence occupied by the PUCCH resources for transmitting the CSI reports may be performed according to the following steps:

step 1: if unprocessed CSI reports also exist in the CSI report set, judging whether the first CSI report collides with a second CSI report, wherein a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol occupied by a PUCCH resource of the first CSI report is earliest in a first OFDM symbol set, a starting OFDM symbol occupied by a PUCCH resource of the second CSI report is latest in a second OFDM symbol set, the first OFDM symbol set is a set of OFDM symbols occupied by the unprocessed CSI reports of the CSI report set, and the second OFDM symbol set is a set of starting OFDM symbols occupied by the PUCCH resource of the CSI reports reserved by the CSI report set.

Of course, it should be understood that the first CSI report is one CSI report selected from a plurality of unprocessed CSI reports in the CSI report set according to a preset rule if an earliest OFDM symbol in the first OFDM symbol set corresponds to the plurality of unprocessed CSI reports in the CSI report set. Specifically, the preset rule, for example, selects the CSI report with the highest priority when the starting OFDM symbols are the same, and the like. Of course, other preset rules are possible.

It should be understood that if CSI report 1 and CSI report 2 are unprocessed and the starting OFDM symbols of the PUCCH resources of CSI report 1 and CSI report 2 are both symbol 1, then symbol 1 corresponds to CSI report 1 and CSI report 2.

Step 2: if the first CSI report collides with the second CSI report, discarding the CSI report with low priority in the first CSI report and the second CSI report in the CSI report set, and reserving the CSI report with high priority in the first CSI report and the second CSI report in the CSI report set; otherwise, reserving the first CSI report and the second CSI report in the CSI report set.

It should be understood that for the CSI report set, steps 1 and 2 may be performed in a loop until there are no unprocessed CSI reports in the CSI report set.

Taking the collision group as the CSI report set as an example, the scenario of fig. 2 and 3 is illustrated.

For the collision set { CSI report 1, CSI report 2, CSI report 3} of the scenario of fig. 2, the priorities of CSI report 1 and CSI report 2 are first compared, CSI report 1 is retained according to the priorities, and CSI report 2 is discarded; and then judging whether the CSI report 1 and the CSI report 3 collide, reserving the CSI report 1 according to the priority and discarding the CSI report 3 because of the collision between the CSI report 1 and the CSI report 3.

For the collision set { CSI report 4, CSI report 5} of the scenario of fig. 2, CSI report 4 and CSI report 5 are compared, and the two collide, leaving CSI report 4 on priority.

At this time, CSI reports 1 and 4 remain on the component carriers.

For the collision set { CSI report 1, CSI report 2, CSI report 3} of the scenario of fig. 3, the priorities of CSI report 1 and CSI report 2 are first compared, CSI report 1 is retained according to the priorities, and CSI report 2 is discarded; and then judging whether the CSI report 1 and the CSI report 3 collide, and reserving the CSI report 1 and the CSI report 3 as the CSI report 1 and the CSI report 3 do not collide.

For the collision set { CSI report 4, CSI report 5} of the scenario of fig. 3, CSI report 4 and CSI report 5 are compared, and the two collide, leaving CSI report 4 on priority.

At this time, CSI reports 1, 3, and 4 remain on the component carriers.

Taking all the CSI reports that have collided as a CSI report set as an example, the scenario of fig. 2 and 3 is exemplified.

For the scenario of FIG. 2:

step 1: and taking out the CSI report 1 and the CSI report 2, and comparing the priority of the CSI report 1 and the priority of the CSI report 2. CSI report 1 is retained according to priority and CSI report 2 is discarded.

Step 2: and judging whether the CSI report 1 and the CSI report 3 collide. Due to the collision, the CSI report 1 is reserved according to the priority, and the CSI report 3 is discarded.

And step 3: and judging whether the CSI report 1 and the CSI report 4 collide. Since the two do not collide, CSI report 1 and CSI report 4 remain.

And 4, step 4: and judging whether the CSI report 4 and the CSI report 5 collide. CSI report 4 is retained due to the collision of the two.

At this time, CSI reports 1 and 4 remain on the component carriers.

For the scenario of FIG. 3:

step 1: and taking out the CSI report 1 and the CSI report 2, comparing the priority of the CSI report 1 and the priority of the CSI report 2, reserving the CSI report 1 according to the priority, and discarding the CSI report 2.

Step 2: and judging whether the CSI report 1 and the CSI report 3 collide. Since the two do not collide, CSI report 1 and CSI report 3 remain.

And step 3: and judging whether the CSI report 1 and the CSI report 4 collide. Since the two do not collide, CSI report 3 and CSI report 4 remain.

At this time, CSI reports 1 and 4 remain on the component carriers.

Of course, it should be understood that, in the embodiment of the present invention, for a CSI report that is not collided on a PUCCH resource of a component carrier, the CSI report may be sent on a PUCCH resource corresponding to the CSI report, and specific implementation may refer to the prior art and is not described again.

Furthermore, it should be understood that fig. 2 and fig. 3 are only two exemplary scenarios according to the embodiment of the present invention, and in a specific application, the collided CSI report may include one or more collision groups, and the CSI report that needs to be transmitted on the PUCCH resource of the component carrier may also include an un-collided CSI report, which is not limited by the embodiment of the present invention.

In some embodiments of the present invention, a method is provided how to indicate a slot offset Y for a-CSI report transmission when only an Aperiodic Channel State Information (a-CSI) request is included in Downlink Control Information (DCI).

The method comprises the following steps:

and sending a DCI format 0_1 message, wherein the DCI format 0_1 message comprises a new field which is used for indicating a time slot offset Y of A-CSI report sending.

Specifically, a field may be newly added in the existing DCI format 0_1, and the value of the newly added field is used to indicate a slot offset Y of the a-CSI report transmission. The method of newly adding the field can flexibly configure the time slot offset of the PUSCH used by the A-CSI report, and information such as mapping type, starting Symbol and Length Indication (SLIV).

For example, the value of the newly added field corresponds to a sequence number in a Report Slot Offset List (Report Slot Offset List) configured by Radio Resource Control (RRC) shown in table 1. For example, if the value of the newly added field is 2, it may be determined that the slot offset Y of the a-CSI report transmission is Y₂. Y in Table 1_nIs an integer of 0 to 7, and n is 1,2, … 16.

TABLE 1Report Slot Offset List

Or, the value of the newly added field corresponds to the sequence number in the RRC configured pusch-Allocation List shown in table 2, and K in table 2_nIs an integer of 0 to 7, and n is 1,2, … 16. E.g. if the newly added fieldIf the value is 6, it can be determined that the time slot offset Y of the a-CSI report transmission is K₆. And may further obtain information such as Mapping Type (Mapping Type) of PUSCH, starting Symbol and Length Indication (SLIV), and further obtain a time domain configuration for transmitting an a-CSI report as shown in table 3.

TABLE 2 Pusch-Allocation List

Serial number	Time slot offset	Mapping type	Starting symbol S and length L in time slot
				1	K₁	A	[S₁L₁]
2	K₂	B	[S₂L₂]
				3	K₃	B	[S₃L₃]
4	K₄	A	[S₄L₄]
				…	…
16	K₁₆	A	[S₁₆L₁₆]

TABLE 3

Time slot offset	Starting symbol S and length L in time slot
		Y₆	[S₆L₆]

The second method comprises the following steps:

and sending a DCI format 0_1 message, wherein the time domain resource configuration field in the DCI format 0_1 message is also used for indicating a time slot offset Y of the A-CSI report sending.

Specifically, by multiplexing a Time Domain Resource Assignment (Time Domain Resource Assignment) field in the DCI format 0_1, a value of the Time Domain Resource Assignment field indicates a slot offset Y of a-CSI report transmission. The method for multiplexing the Time Domain Resource Assignment field can configure the Time slot offset of the PUSCH used by the A-CSI report, and information such as mapping type, starting Symbol and Length Indication (SLIV) and the like on the basis of not increasing signaling overhead.

For example, the value of the Time Domain Resource Assignment field corresponds to the sequence number in table 1. Or the value of the Time Domain Resource Assignment field corresponds to the sequence number in table 2. For example, if the Time domain resource assignment field is 9, the Time domain configuration for transmitting the a-CSI report shown in table 4 can be obtained according to table 2.

TABLE 4

Time slot offset	Starting symbol S and length L in time slot
		Y₉	[S₉L₉]

In still other embodiments of the present invention, a method for determining a quantity of Channel Quality Indicators (CQIs) is also provided. Specifically, the number of CQIs is determined according to the value of the RRC parameter nroflcqisperreport.

For example, if the RRC parameter nrofCQIsPerReport is 1, the number of CQIs is determined to be 1 regardless of the value (1-8) of the RI of the CSI report. When calculating the reported CQI, the Signal to Interference plus Noise Ratio (SINR) of all layers may be mapped to one Codeword (coded) to calculate the reported 1 CQI (wideband CQI or subband CQI), or the SINR of layers 1 to min { RI,4} may be mapped to one Codeword to calculate the reported 1 CQI (wideband CQI or subband CQI), and the other layers do not perform reporting.

Or for another example, if the RRC parameter nrofCQIsPerReport is 1 and the RI limit of the CSI report of the terminal device is 4 at maximum, the number of CQIs is determined to be 1. When the reported CQI is calculated, the layer 1 to RI are mapped to code words according to the existing rule to calculate the reported 1 CQI.

Or for another example, if the RRC parameter nrofCQIsPerReport is 2, determining a mapping manner of a layer to a codeword according to an RI of a CSI report of the terminal device according to an existing rule, and calculating a report CQI.
