It will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the disclosure. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In the various embodiments of the present disclosure, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not be implemented by the present disclosure. The implementation of the examples constitutes any limitation.

The present disclosure provides a scheme for transmitting aperiodic channel state information A-CSI using PUCCH resources for the requirements of the 5G communication network in the related art.

In one aspect, an embodiment of the present disclosure provides a method for transmitting aperiodic channel state information, which is applied to a terminal device (for example, a mobile communication terminal, such as a mobile phone, a PAD, etc.), as shown in FIG.

Step 101: Receive downlink control information DCI for downlink scheduling sent by the network side, where the DCI carries: indication information for indicating whether the terminal device reports the aperiodic channel state information A-CSI to the network side;

Step 102: If the DCI instructs the terminal device to report the A-CSI to the network side, the A-CSI is sent to the network side by using the resource of the physical uplink control channel PUCCH.

The embodiment provides a scheme for transmitting A-CSI by using a resource of a PUCCH: the DCI of the downlink scheduling is used to instruct the terminal device to report the A-CSI. The DCI of the current downlink scheduling may instruct the terminal to use the resource of the PUCCH to send the hybrid automatic retransmission request information HARQ-ACK for the network side scheduling PDSCH transmission. Therefore, the DCI of the downlink scheduling is multiplexed to instruct the terminal device to report the A-CSI. The signaling overhead of controlling the resources of the terminal device using the PUCCH may be simplified, and the A-CSI and the HARQ-ACK for transmitting the resources of the appropriate PUCCH for controlling the terminal device are also convenient to prevent the A-CSI and the HARQ-ACK from generating a transmission collision.

The following describes how the transmission method of this embodiment uses the PUCCH resource to send A-CSI.

Specifically, the DCI and/or RRC signaling of the downlink scheduling may be used by the terminal device to instruct the terminal device to send the A-CSI by using the resource of the PUCCH.

As an example, the DCI further carries the indication information for indicating the resource of the PUCCH used by the terminal device to transmit the A-CSI, and/or is used to instruct the terminal device to send the A-CSI. Indication information of the time slot;

When performing the above step 102, the terminal device transmits the A-CSI using the resources of the PUCCH indicated in the DCI and/or using the time slot indicated in the DCI.

For the same reason, the RRC signaling indicates that the A-CSI is sent, and the RRC signaling carries: indication information for instructing the terminal device to send the PUCCH resource used by the A-CSI; when performing the foregoing step 102, the terminal receives the network side to send. The RRC signaling, and transmitting the A-CSI using the resources of the PUCCH indicated in the RRC signaling.

It should be noted that, in this embodiment, the network side may specifically indicate the time slot of the A-CSI sent by the terminal device, or may also specify that the terminal device sends the A-CSI in the default time slot by using a protocol.

The protocol specifies that the terminal device sends the A-CSI in the default time slot as an example: if the terminal device receives the DCI in the subframe n, then the A-CSI is sent on the subframe n+k, where k is a positive integer.

In an actual application, the DCI further carries indication information for instructing the terminal device to send the PUCCH resource used by the A-CSI.

As a preferred solution, if the DCI indicates that the terminal device reports the A-CSI to the network side, and the network side schedules the physical downlink channel PDSCH, the embodiment may multiplex the transmission time slot of the HARQ-ACK to send the A-CSI. That is, the time domain interval of the DCI and the A-CSI on the transmission is equal to the time domain interval of the hybrid automatic repeat request information HARQ-ACK of the DCI and the PDSCH (for example, the DCI transmission time slot and the A-CSI transmission time slot) The interval between slots is equal to the slot interval of the DCII transmission slot and the HARQ-ACK transmission slot).

Based on the above solution, the transmission method of this embodiment can no longer additionally indicate the transmission slot of the A-CSI, thereby simplifying the information transmission amount.

It should be noted here that the resources of the PUCCH for transmitting the A-CSI and the resources of the PUCCH for transmitting the HARQ-ACK configured by the DCI and/or RRC signaling for the terminal device may be the same or different.

As a preferred solution, if the DCI instructs the terminal device to report the A-CSI to the network side, and the network side schedules the physical downlink channel PDSCH, the terminal device can simultaneously send the A-CSI and the HARQ-ACK on the same PUCCH resource, thereby reducing Signaling overhead.

As an exemplary introduction, the terminal device in this embodiment may jointly encode the data of the A-CSI and the data of the HARQ-ACK, and send the data to the network side on the same PUCCH resource; or, the data of the A-CSI is used. The data of the HARQ-ACK is separately encoded and sent to the network side on the same PUCCH resource.

Wherein, if the terminal device sends the data of the A-CSI and the HARQ-ACK to the network side,

The DCI of the different PDSCHs corresponding to the HARQ-ACKs transmitted by the same PUCCH carries the same information domain content for indicating whether the terminal equipment reports A-CSI.

That is, the network side may send multiple DCIs to the terminal device, and the different DCIs are used to indicate that the network side invokes different PDSCH transmissions. If the multiple DCIs are corresponding to the HARQs, the terminal equipment uses the same PUCCH transmission to send these different PDSCHs. - ACK, the above multiple DCIs may use the same information field for indicating whether the terminal device reports A-CSI.

It should be noted that, in the actual application, even if the above-mentioned DCI and/or RRC signaling configures the A-CSI transmission resource to be different from the HARQ-ACK transmission resource, the DCI indicates that the terminal device reports to the network side. A-CSI, and the network side schedules the physical downlink channel PDSCH, the terminal device also uses only one of the resources to simultaneously transmit A-CSI and HARQ-ACK. For example, the terminal device sends the A-CSI and the HARQ-ACK together to the network side using the resources of the PUCCH that sends the HARQ-ACK; or the terminal device uses the resources of the PUCCH that sends the A-CSI to A-CSI and HARQ-ACK. Send it to the network side.

Obviously, based on the above-mentioned combined transmission design, it is possible to effectively avoid A-CSI and HARQ-ACK from generating a transmission collision.

On the other hand, another embodiment of the present disclosure further provides a method for transmitting aperiodic channel state information, which is applied to a network device (which may be an upstream node of a terminal device, such as a base station), as shown in FIG. 2, including:

Step 201: Send downlink control information DCI for downlink scheduling to the terminal device, where the DCI includes: indication information for indicating whether the terminal device reports the aperiodic channel state information A-CSI to the network side;

Step 202: If the DCI instructs the terminal device to report the A-CSI to the network side, the A-CSI sent by the terminal device in response to the DCI is received.

Obviously, the method for transmitting the aperiodic channel state information of the network device in this embodiment corresponds to the method for transmitting the aperiodic channel state information applied to the terminal device provided by the previous embodiment of the present disclosure, so that the same technical effect can be achieved. .

In a practical application, the network device in this embodiment may use the DCI to instruct the terminal device to send the A-CSI by using the resource of the PUCCH.

That is, the foregoing DCI of the present embodiment further carries: indication information for instructing the terminal device to send the resource of the PUCCH used by the A-CSI, and/or indication information for indicating the time slot used by the terminal device to send the A-CSI;

The terminal device transmits the A-CSI using the resources of the PUCCH indicated in the DCI and/or using the time slot indicated in the DCI.

Alternatively, the network device in this embodiment may indicate, by using RRC signaling, that the terminal device sends the A-CSI by using the resource of the PUCCH.

That is, the RRC signaling carries the indication information for instructing the terminal device to send the PUCCH resource used by the A-CSI; the terminal receives the RRC signaling sent by the network side, and can send the A-CSI by using the resource of the PUCCH indicated in the RRC signaling. .

The DCI carries indication information for instructing the terminal device to send the PUCCH resource used by the A-CSI.

As a preferred solution, if the DCI instructs the terminal device to report the A-CSI to the network side, and the network side schedules the physical downlink channel PDSCH, the terminal device may multiplex the transmission time slot of the HARQ-ACK to send the A-CSI.

That is, the time domain interval of the DCI and A-CSI on the transmission is equal to the time domain interval of the hybrid automatic repeat request information HARQ-ACK of the DCI and the PDSCH on the transmission.

Based on the above design, the network device can receive the A-CSI sent by the terminal device on the time slot in which the receiving terminal sends the HARQ-ACK.

It should be noted that the resources of the PUCCH used by the terminal device to transmit the A-CSI and the resources of the PUCCH used for transmitting the HARQ-ACK may be the same or different.

Of course, as a preferred solution, if the DCI instructs the terminal device to report the A-CSI to the network side, and the network side schedules the physical downlink channel PDSCH, the terminal device may simultaneously send the A-CSI and the HARQ-ACK on the same PUCCH resource. Thereby reducing the signaling overhead.

Correspondingly, when performing the above step 202, the network device receives the data of the A-CSI and the HARQ-ACK that are sent by the terminal device together, and parses the data corresponding to the A-CSI from the received data respectively. The data of the HARQ-ACK.

It can be known that the resources of the PUCCH fed back by the terminal device received by the network device in this embodiment in step 202 exist in three cases.

One is that the field in the DCI indicates that the terminal device reports the A-CSI, but does not indicate that the network side has the scheduled PDSCH transmission, and the network device only parses the A-CSI data on the PUCCH resource fed back by the terminal device;

The other one is that the field in the DCI does not indicate that the terminal device reports the A-CSI, but indicates that the network side schedules the transmission of the PDSCH, and the network device detects only the HARQ-ACK corresponding to the PDSCH transmission on the resource of the PUCCH fed back by the terminal device. ;

The last one is that the field in the DCI indicates that the terminal device reports the A-CSI, and also indicates that the network side has the scheduled PDSCH transmission, and the base station simultaneously parses the HARQ corresponding to the A-CSI and the PDSCH transmission on the PUCCH resource fed back by the terminal device. ACK.

In a practical application, the method for the network device in this embodiment to parse the data of the A-CSI is consistent with the data-party coding method of the A-CSI by the terminal device.

For example, the terminal device jointly encodes the bits of the A-CSI and the bits of the HARQ-ACK and sends them to the network side, and the network device receives, and parses the A-CSI data and the HARQ-ACK from the jointly encoded data. The data.

For example, the terminal device independently encodes the bits of the A-CSI and the bits of the HARQ-ACK, and sends the bits of the A-CSI separately to the network side, and after receiving the two independently encoded data, the network device separately parses the A-CSI. Data and HARQ-ACK data.

In addition, if the terminal device sends the A-CSI data together with the HARQ-ACK to the network side, then

That is, the network device of the present embodiment may send multiple DCIs to the terminal device, where different DCIs are used to instruct the network side to invoke different PDSCH transmissions, and if the multiple DCIs are corresponding to the terminal device transmitting the different PDSCHs by using the same PUCCH transmission. In the case of the HARQ-ACK, the multiple DCIs may use the same information field for indicating whether the terminal device reports the A-CSI.

The following describes the transmission method of the aperiodic channel state information of the present disclosure in combination with the terminal device and the network device in different practical applications.

Practical application

In this implementation application, the terminal device is a user equipment UE, and the network device is a base station of the UE.

It is assumed that in slot n, the base station schedules PDSCH (Physical Downlink Channel) transmission, and transmits the HARQ-ACK feedback information of the PDSCH in slot n+4 by DCI, and also instructs the UE to transmit A-CSI in the DCI. The base station configures four groups of PUCCH (Physical Uplink Control Channel) resources for the UE by using RRC signaling, and the four groups of PUCCH resources are used for transmission of HARQ-ACK and/or A-CSI, and the base station dynamically indicates by using 2 bits in the DCI. Which of the PUCCH resources is used. Then, after receiving the DCI, the UE receives the PDSCH according to the DCI indication, and simultaneously transmits the HARQ-ACK feedback information and the A-CSI of the PDSCH on the PUCCH resource indicated by the DCI in the slot n+4.

It is assumed that the base station is configured with the dynamic codebook feedback mode. When the single carrier transmission is configured and the PDSCH is single codeword transmission, if the base station schedules only one PDSCH transmission in one DAI window, the UE needs to feed back 1-bit HARQ- ACK. Assuming that the A-CSI that the UE needs to feed uses 8 bits, the UE feeds back a total of 9 bits of information on the PUCCH resource indicated by the DCI, and the UE cascades 1 bit of the HARQ-ACK and 8 bits of the A-CSI, and then These 9 bits are encoded together and transmitted.

Practical application two

It is assumed that in slot n, the base station does not schedule transmission of the PDSCH, and only indicates that the UE transmits A-CSI through DCI. Although the base station does not schedule PDSCH transmission, the 2-bit information is still included in the DCI to indicate the transmission location of the A-CSI or the transmission location of the A-CSI can be obtained in the slot n+4 by the UE through a predefined timing relationship. The base station configures four groups of PUCCH resources for the UE by using RRC signaling, where the four groups of PUCCH resources are used for transmission of HARQ-ACK and/or A-CSI, and the base station dynamically indicates which one of the PUCCH resources is used by using 2 bits in the DCI. . After receiving the DCI, the UE transmits the A-CSI on the PUCCH resource indicated by the DCI in the slot n+4 according to the DCI indication.

It is assumed that the base station configures the feedback mode of the UE using the semi-static codebook. When the single carrier transmission is configured and the PDSCH is a single codeword transmission, if the base station configures a DAI window of up to 4 (that is, there are up to 4 on the same carrier). The slots are fed back on one PUCCH resource at the same time, and the UE needs to feed back 4-bit HARQ-ACK. Assuming that the A-CSI that the UE needs to feed uses 10 bits, the UE feeds back 14 bits of information on the PUCCH resources indicated by the DCI, and the UE cascades 4 bits of the HARQ-ACK and 10 bits of the A-CSI, and then These 14 bits are encoded together and transmitted.

In addition, as shown in FIG. 3, another embodiment of the present disclosure further provides a terminal device 300, including:

The first receiving module 301 is configured to receive downlink control information DCI for downlink scheduling sent by the network side, where the DCI carries: indication information for indicating whether the terminal device reports the aperiodic channel state information A-CSI to the network side. ;

The first sending module 302 is configured to send the A-CSI to the network side by using the resource of the physical uplink control channel PUCCH, if the DCI instructs the terminal device to report the A-CSI to the network side.

Obviously, the terminal device in this embodiment is the implementation body of the foregoing method for transmitting the aperiodic channel state information applied to the terminal device provided by the present disclosure, and therefore the technology applicable to the method for transmitting the aperiodic channel state information of the terminal device The effect is that the terminal device of the embodiment can also be implemented.

Optionally, if the DCI indicates that the terminal device reports the A-CSI to the network side, and the network side schedules the physical downlink channel PDSCH, the time interval of the DCI and the A-CSI on the transmission is equal to the DCI and The time interval of the hybrid automatic repeat request information HARQ-ACK of the PDSCH on the transmission.
