For convenience of description, the following examples are illustrated with the gNB as an example.

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 schematic diagram of a communication system according to an embodiment of the present invention, where the communication system includes a base station and a UE, the base station is configured to indicate a first resource to the UE, and the UE determines, according to the first resource indicated by the base station, a resource for sending CSI to the base station, and sends the CSI to the base station on the resource. Both the UE and the base station may perform the method for configuring CSI transmission resources in the embodiments of the present invention, which will be specifically described in the following method embodiments and will not be further described herein.

The following describes an exemplary configuration method of CSI transmission resources provided by the embodiment of the present invention with reference to the base station and the UE shown in fig. 1.

Fig. 2 is an interactive flow diagram of a method for configuring CSI transmission resources according to an embodiment of the present application, including the following steps 101 to 104:

step 101, a base station, e.g. a gbb, indicates a first resource to a UE.

Wherein the first resource is used for the UE to transmit CSI.

Specifically, the first resource may include a time domain resource and a frequency domain resource.

Optionally, the gNB may indicate the first resource to the UE through a predefined indication information. Specifically, the gNB may send the predefined indication Information to the UE by carrying the predefined indication Information in Downlink Control Information (DCI).

Optionally, in this embodiment of the present invention, the gNB may indicate the first resource to the UE by indicating the identifier of the first resource to the UE. The identifier of the first resource may be a resource number of the first resource, and the like, which is not specifically limited in this embodiment of the present invention.

Step 102, the UE acquires a first resource indicated by the gNB.

And step 103, the UE sends the CSI on the first resource indicated by the gNB.

And step 104, the gNB receives the CSI sent by the UE on the first resource.

According to the configuration method of the CSI transmission resource provided by the embodiment of the invention, when the gNB needs to acquire the CSI, the gNB can indicate the first resource for the UE to send the CSI to the gNB, so that the gNB can send the CSI configuration resource for the UE.

Optionally, in this embodiment of the present invention, the CSI sent by the UE to the gNB may be aperiodic CSI.

Based on the scheme, the UE can send the aperiodic CSI to the gNB on the first resource indicated by the gNB, and the UE sends the aperiodic CSI only when the gNB indicates the UE to send the aperiodic CSI, so that the aperiodic CSI can accurately reflect the current channel quality, and after the gNB acquires the aperiodic CSI, the gNB can accurately estimate the current channel quality according to the aperiodic CSI, and the gNB can accurately schedule the UE.

In one possible implementation, the first resource is the same as a second resource for the UE to send an acknowledgement message to the gNB.

The Acknowledgement message in the embodiment of the present invention may include an Acknowledgement (ACK) and a packet loss retransmission (NACK). ACK means that the UE has successfully received the indication information. NACK indicates that the UE has not successfully received the indication information, for example, an error occurs when the UE checks the indication information, and at this time, the gNB may confirm that the indication information needs to be retransmitted.

Optionally, the ACK may be an ACK of a Hybrid Automatic Repeat Request (HARQ) of a Physical Downlink Shared Channel (PDSCH).

Based on the scheme, the gNB can indicate that the first resource for the UE to send the CSI is the same as the second resource for the UE to send the confirmation message, so that the utilization rate of the resources is improved.

In a possible implementation manner, in the configuration method of CSI transmission resources, the step 101 may be specifically implemented by the step 101a, and the step 102 may be specifically implemented by the step 102 a.

Step 101a, the gNB indicates the second resource and the first indication information to the UE.

Wherein the first indication information is used for indicating the UE to transmit the CSI on the second resource.

Step 102a, the UE acquires the second resource and the first indication information indicated by the gNB.

For example, fig. 3 is a schematic diagram of a configured resource provided in an embodiment of the present invention, as shown in fig. 3, a gNB configures 4 resource sets for a UE, each resource set corresponds to a different resource range, where the resource range corresponding to resource set 1 is [1bits, 2bits ], the resource range corresponding to resource set 2 is [3bits, N1bits ], the resource range corresponding to resource set 3 is [ (N1+1) bits, N2bits ], and the resource range corresponding to resource set 4 is [ (N2+1) bits, N3bits ]. Wherein the resources in each resource set have PUCCH format groups supporting different resources, and each group includes a long (long) PUCCH format and a short (short) PUCCH format. The gNB may indicate which PUCCH is used by the UE, and thus may select PUCCHs of different lengths and different resource ranges.

For example, if the gNB indicates that the 2-symbol short PUCCH in resource set 2 in fig. 3 is the first resource, the UE may send the CSI-bearing short PUCCH to the gNB according to the 2-symbol in resource set 2.

In the embodiment of the present invention, the gNB may instruct the UE to send CSI on the second resource for sending the acknowledgement message. Thus, the utilization rate of resources can be improved.

In order to avoid that the second resource and the first indication information indicated to the UE by the gNB may be lost due to channel quality deterioration, the gNB may indicate the second resource and the first indication information to the UE in the following manner.

In a possible implementation manner, in the CSI transmission resource configuration method, the step 101a may be specifically implemented by the step 101a1, and the step 102a may be specifically implemented by the step 102a 1.

Steps 101a1, gNB indicate the first resource and the first indication information on the plurality of first and second PDCCHs, respectively.

Each first PDCCH in the plurality of first PDCCHs is used to indicate a first resource, the plurality of first PDCCHs are PDCCHs located after a second PDCCH in the bundling window, and the second PDCCH is a PDCCH indicating the first resource and the first indication information in the bundling window.

Fig. 4 is a schematic diagram of a binding window according to an embodiment of the present invention. Assuming that a PDCCH 1 corresponding to a slot (slot) a of the bundling window is a first PDCCH indicating the first resource and the first indication information, the first resource and the first indication information are also indicated on a plurality of PDCCHs 2 corresponding to the slot a and the slot a in the drawing.

Step 102a1, the UE acquires the second resource and the first indication information indicated by the gNB on one first PDCCH or a second PDCCH of the plurality of first PDCCHs.

Based on the scheme, the first resource and the first indication information are indicated on a plurality of first PDCCHs in the binding window, so that the problem that the first resource and the first indication information indicated on the second PDCCHs are lost can be avoided.

In one possible implementation manner, the first resource is the same as a second resource for the UE to send the acknowledgement message to the gNB, and the first resource is a resource in a predefined resource set; in the above CSI transmission resource configuration method, step 101 may be specifically implemented by step 101b, and step 102 may be specifically implemented by steps 102b to 102 c.

And step 101b, the gNB sends second indication information to the UE, wherein the second indication information is used for indicating the first resource.

And 102b, the UE receives second indication information sent by the gNB.

And step 102c, the UE acquires the first resource indicated by the gNB according to the second indication information.

Illustratively, table 1 is an example of a resource configuration provided in an embodiment of the present invention. Taking HARQ acknowledgement messages and a-CSI as an example, where the a-CSI indicates that CSI sent by the gNB is aperiodic CSI.

TABLE 1

00	HARQ	A/N resource 1
			01	HARQ	A/N resource 2
10	HARQ and A-CSI	Resource set 1{ A/N resource 3, A-CSI resource 1}
			11	HARQ and A-CSI	Resource set 2{ A/N resource 4, A-CSI resource 2}

As shown in Table 1, the A/N in Table 1 indicates ACK/NACK. "00" in table 1 indicates that resource 1 is used when a/N is transmitted. "01" indicates that resource 2 is used when transmitting the A/N. "10" indicates that resource set 1 is used when both a/N and a-CSI are transmitted, and resource 3 in the resource set is used when a/N is transmitted and resource 1 in the resource set is used when a-CSI is transmitted. "11" indicates that resource set 2 is used when both A/N and A-CSI are transmitted, and that resource 4 in the resource set is used when A/N is transmitted and resource 2 in the resource set is used when A-CSI is transmitted.

It should be noted that in this scheme, a separate indication information is not needed to indicate that the aperiodic CSI is triggered, but the indication information of the gNB implicitly indicates the resource used for sending the aperiodic CSI.

It can be understood that, in the embodiment of the present invention, if "00" indicates transmission of ACK, then "01" indicates transmission of NACK; alternatively, if "00" indicates transmission of NACK, "01" may indicate transmission of ACK.

Based on the scheme, after the UE receives the second indication information sent by the gNB, the UE may determine, according to the second indication information, the first resource, indicated by the gNB, for the UE to send the CSI.

In one possible implementation, the first resource is different from a second resource for the UE to send the acknowledgement message to the gNB; in the above CSI transmission resource configuration method, step 101 may be specifically implemented by step 101c, and step 102 may be specifically implemented by steps 102d to 102 e.

Step 101c, the gNB sends third indication information to the UE, where the third indication information is used to indicate the first resource and the second resource.

And step 102d, the UE receives third indication information sent by the gNB.

And step 102e, the UE acquires the first resource and the second resource indicated by the gNB according to the third indication information.

Table 2 is an example of another resource configuration provided in the embodiment of the present invention.

TABLE 2

	Resource of HARQ-acknowledgement message	Resources for A-CSI and HARQ-acknowledgment messages
			00	A/N resource 1	Resource set 1{ A/N resource 1, A-CSI resource 1}

			10	A/N resource 3	Resource set 3{ A/N resource 3, A-CSI resource 3}
11	A/N resource 4	Resource set 4{ A/N resource 4, A-CSI resource 4}

As shown in Table 2, the A/N in Table 2 indicates ACK/NACK. "00" in Table 2 indicates that resource 1 is used when A/N is transmitted; resource set 1 is used when transmitting A/N and A-CSI, and resource 1 in resource set 1 is used when transmitting A/N, and resource 1 in resource set is also used when transmitting A-CSI. "01" indicates that resource 2 is used when transmitting A/N; resource set 2 is used when transmitting A/N and A-CSI, and resource 2 in resource set 2 is used when transmitting A/N, and resource 2 in resource set 2 is also used when transmitting A-CSI. "10" indicates that resource 3 is used when transmitting A/N; resource set 3 is used when transmitting A/N and A-CSI, and resource 3 in resource set 3 is used when transmitting A/N, and resource 3 in resource set 3 is also used when transmitting A-CSI. "11" indicates that resource 4 is used when transmitting A/N; resource set 4 is used when transmitting A/N and A-CSI, and resource 4 in resource set 4 is used when transmitting A/N, and resource 4 in resource set 4 is also used when transmitting A-CSI.

Based on the scheme, after the UE receives the third indication information sent by the gNB, the UE may determine, according to the third indication information, a first resource, indicated by the gNB, for the UE to send the CSI and a second resource, indicated by the gNB, for the UE to send the acknowledgment message.

It should be noted that in this scheme, a separate field is required to indicate whether to trigger aperiodic CSI, where the field indicates whether the UE uses the first resource to send an acknowledgement message, or simultaneously uses the first resource to send CSI and the second resource to send an acknowledgement message.

In one possible implementation, the first resource is different from a second resource for the UE to send the acknowledgement message to the gNB; in the above configuration method for CSI transmission resources, step 101 may be specifically implemented by step 101d, and step 102 may be specifically implemented by steps 102f to 102 g.

101d, the gNB sends fourth indication information and fifth indication information to the UE, the fourth indication information is used for indicating the first resource, and the fifth indication information is used for indicating the second resource.

And 102f, the UE receives the fourth indication information and the fifth indication information sent by the gNB.

102g, the UE acquires the first resource indicated by the gNB according to the fourth indication information; and acquiring the second resource indicated by the gNB according to the fifth indication information.

Exemplarily, table 3-1 is an example of a corresponding relationship between the fourth indication information and the resources configured for the a-CSI provided by the embodiment of the present invention.

TABLE 3-1

00	Non-triggering A-CSI on short PUCCH transmission
		01	Triggering A-CSI on short PUCCH transmission, resource 1
10	Triggering A-CSI on short PUCCH transmission, resource 2
		11	Triggering A-CSI on short PUCCH transmission, resource 3

As shown in Table 3-1, the A/N in Table 3-1 indicates ACK/NACK. "00" in table 2 indicates that a-CSI is not triggered for transmission on the short PUCCH. "01" indicates triggering a-CSI on short PUCCH transmission, indicating use of resource 1 in the resource set when transmitting a-CSI. "10" indicates triggering a-CSI on short PUCCH transmission, indicating use of resource 2 in the resource set when transmitting a-CSI. "11" indicates triggering a-CSI on short PUCCH transmission, indicating use of resource 3 in the resource set when transmitting a-CSI.

Table 3-2 is an example of a correspondence relationship between the fifth indication information and the resources configured for HARQ-ACK according to the embodiment of the present invention.

TABLE 3-2

	Resource of HARQ-acknowledgement message
		00	A/N resource 1
01	A/N resource 2
		10	A/N resource 3
11	A/N resource 4

As shown in Table 3-2, the A/N in Table 3-2 indicates ACK/NACK. "00" in table 2 indicates that resource 1 in the resource set is used when a/N is transmitted. "01" indicates that resource 2 in the resource set is used when the A/N is transmitted. "10" indicates that resource 3 in the resource set is used when the A/N is transmitted. "11" indicates that resource 4 in the resource set is used when the A/N is transmitted.

Based on the scheme, after receiving the fourth indication information and the fifth indication information sent by the gNB, the UE may determine, according to the fourth indication information, the first resource, indicated by the gNB, of the UE for sending the CSI and determine, by the UE, the second resource, indicated by the gNB, of the UE for sending the acknowledgment message.

It should be noted that in this scheme, a separate indication information is not needed to indicate that aperiodic CSI is triggered, but indication information of the gNB indicates whether aperiodic CSI is sent or not.
