Description

Method and device for determining process number of hybrid automatic repeat request

Background

In a communication system, for feedback disable disabled of Hybrid Automatic Repeat request (HARQ) for dynamic scheduling (DG), HARQ feedback may be disabled in each HARQ process through Radio Resource Control (RRC) signaling. In a New Radio (NR) network and a Terrestrial Network (TN) network, a Configuration Grant (CG) may multiplex an HARQ process number (ID) with a DG.

The embodiments of the present disclosure do not limit the specific technology and the specific device form adopted by the terminal device.

It is to be understood that the communication system described in the embodiment of the present disclosure is for more clearly illustrating the technical solutions of the embodiment of the present disclosure, and does not constitute a limitation to the technical solutions provided in the embodiment of the present disclosure, and as a person having ordinary skill in the art knows that as the system architecture evolves and new service scenarios appear, the technical solutions provided in the embodiment of the present disclosure are also applicable to similar technical problems.

The method for determining a harq process number and the apparatus thereof provided in the present disclosure are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a terminal device. As shown in fig. 2, the method may include, but is not limited to, the following steps:

step 21, receiving first indication information, where the first indication information is used to indicate a first hybrid automatic repeat request HARQ process number process ID of a first number of dynamically scheduled DGs and a second HARQ process ID of a second number of configuration grants CG, where the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of an indicated HARQ process ID in downlink control information DCI.

It is understood that in NR and TN networks, DG and CG may multiplex the same HARQ process ID pool. However, in the NTN network, if DG and CG still multiplex HARQ process ID pool, the product of RTT and max _ re-trans _ num is greater than the SPS PDSCH period, which results in excessive HARQ process IDs that the CG needs to allocate, and further results in less HARQ process IDs available for DG, thereby reducing the flexibility of DG selecting feedback enabled HARQ process IDs or feedback disabled HARQ process IDs. In the present disclosure, the HARQ process IDs are configured for the DG and the CG, respectively, so that the feedback enabled HARQ process ID and the feedback disabled HARQ process ID in the CG and the DG can be flexibly configured.

The first number and the second number may be any numbers less than or equal to the capability of the terminal device, that is, the second number and the first number may be any numbers less than or equal to the number of HARQ buffer queues supported by the terminal device. For example, if the number of HARQ buffer queues supported by the terminal device is 32, the first number may be 16, 20, 32, etc., and the second number may be 15, 20, 32, etc. The present disclosure is not limited thereto.

It should be noted that the numerical value of the second quantity may be the same as or different from the numerical value of the first quantity, and the disclosure does not limit this.

Optionally, the network device may determine, according to the capability of the terminal device, a maximum value that may indicate the HARQ process ID in the DCI. For example, if the capability of the terminal device is 32, the maximum value of the HARQ process ID that can be indicated in the DCI is 32.

In the present disclosure, in order to solve the problem that the CG and the DG cannot multiplex the HARQ process ID pool in the NTN network, a plurality of HARQ process IDs may be separately configured for the CG and the DG, respectively, and in order to ensure that the HARQ process IDs configured for the CG and the DG, respectively, can meet the requirements of the CG and the DG as much as possible, in the present disclosure, a sum of the first number and the second number may be set to be greater than a maximum value of the HARQ process ID that can be indicated in the DCI.

Optionally, in order to not change the format of the DCI signaling as much as possible, in the present disclosure, the first number and the second number may be set to the same value, that is, the ith second HARQ process ID is the ith first HARQ process ID + the first number, where i is an integer less than or equal to the second number.

For example, if the first number is 32 and the second number is 32, the first HARQ process ID of 32 DGs may be 0-31 and the second HARQ process ID of 32 CGs may be 32-63. If i is 15, the 15 th second HARQ process ID corresponding to the CG may be the 15 th HARQ process ID +32 corresponding to the DG, that is, the 15 th HARQ process ID corresponding to the CG has the following value: 15+32 ═ 47.

It should be noted that the above examples are only simple examples, and are not intended to be specific limitations of the first number, the second number, and the i number in the present disclosure.

Normally, the initial transmission resource of the CG is configured by RRC, and at this time, the terminal device may determine the HARQ process ID of the initial transmission SPS PDSCH according to the formula according to the RRC parameter and the time unit where the SPS PDSCH is located, and under the condition that the original formula is not changed, the HARQ process ID is equal to the original formula calculation value + the first number.

And the retransmission resource of CG is scheduled by DCI, at this time, the terminal device may determine the retransmission HARQ process ID of SPS PDSCH according to the scrambling scheme of DCI and the HARQ process ID value indicated in DCI, where the HARQ process ID is the HARQ process ID indication value + the first number in DCI. The relationship between the DCI scrambling method and the HARQ process ID may refer to the detailed description of other embodiments of the present disclosure, and is not described herein again.

Optionally, the terminal device may receive the first indication information through RRC signaling sent by the network device.

By implementing the embodiment of the present disclosure, the terminal device may determine the HARQ process ID corresponding to the first number of DGs and the second HARQ process ID corresponding to the second number of CGs by receiving the first indication information sent by the network device. Therefore, the terminal equipment is respectively configured with the HARQ process IDs corresponding to the CG and the DG, so that the feedback enabled HARQ process ID and the feedback disabled HARQ process ID in the CG and the DG can be flexibly configured.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a terminal device. As shown in fig. 3, the method may include, but is not limited to, the following steps:

step 31, receiving first indication information, where the first indication information is used to indicate a first HARQ process ID of a first number of DGs and a second HARQ process ID of a second number of CGs, where the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of the indicated HARQ process IDs in the DCI.

The specific implementation form of step 31 may refer to detailed steps in other embodiments in the present disclosure, and details are not described here.

And step 32, receiving second indication information, wherein the second indication information is used for indicating that the first HARQ process ID and the second HARQ process ID are the feedback-enabled HARQ process ID or the feedback-disabled HARQ process ID.

The number of the feedback-enabled HARQ process IDs in the first HARQ process ID may be the same as or different from the number of the feedback-disabled HARQ process IDs, which is not limited in this disclosure.

The number of the feedback-enabled HARQ process IDs in the second HARQ process ID may be the same as or different from the number of the feedback-disabled HARQ process IDs, which is not limited in this disclosure.

The second indication information in the present embodiment may be the same as or different from the first indication information. That is, the network device may simultaneously indicate the first HARQ process ID of the first number of DGs, the second HARQ process ID of the second number of CGs, and the first HARQ process ID and the second HARQ process ID as the feedback-enabled HARQ process ID or the feedback-disabled HARQ process ID through one RRC signaling. Or, the network device may also indicate a first HARQ process ID of a first number of DGs and a second HARQ process ID of a second number of CGs through one RRC signaling; and indicating the first HARQ process ID and the second HARQ process ID as a feedback enabled HARQ process ID or a feedback disabled HARQ process ID through another RRC signaling. The present disclosure is not limited thereto.

By implementing the embodiment of the disclosure, the terminal device determines, by receiving first indication information sent by the network device, a first HARQ process number process ID of a first number of dynamically scheduled DGs and a second HARQ process ID of a second number of configured grants CG, and then determines, according to the received second indication information, that the first HARQ process ID and the second HARQ process ID are feedback-enabled HARQ process IDs or feedback-disabled HARQ process IDs. Therefore, the feedback enabling HARQ process ID and the feedback disabling HARQ process ID in CG and DG are flexibly configured for the terminal equipment.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a terminal device. As shown in fig. 4, the method may include, but is not limited to, the following steps:

step 41, receiving first indication information, where the first indication information is used to indicate a first HARQ process ID of a first number of DGs and a second HARQ process ID of a second number of CGs, where the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of the indicated HARQ process IDs in the DCI.

The specific implementation form of step 41 may refer to detailed steps in other embodiments in the present disclosure, and details are not described here.

And step 42, receiving downlink control information DCI, where the DCI is used to indicate a value of the HARQ process ID corresponding to the resource to be scheduled, where the value of the HARQ process ID corresponding to the resource to be scheduled is smaller than a sum of the first number and the second number.

Generally, the network device may determine the initial HARQ process ID of the SPS PDSCH according to the RRC parameter and the time unit of the PDSCH. When an error occurs in the initial transmission, the retransmission HARQ process ID of the SPS PDSCH can be indicated through the DCI, and the retransmission HARQ process ID indicated in the DCI is the same as the HARQ process ID of the SPS PDSCH with the initial transmission error. That is, the network device may indicate, to the terminal device, a value of the HARQ process ID corresponding to the resource to be scheduled through the DCI.

The resource to be scheduled may be a resource corresponding to CG retransmission or a resource corresponding to DG, that is, the value of the HARQ process ID corresponding to the resource to be scheduled is smaller than the sum of the first number and the second number.

Step 43, decoding the DCI to determine the value of the HARQ process ID contained in the DCI and the corresponding scrambling mode,

wherein, the value of the HARQ process ID contained in the DCI is less than the first number or the second number.

In this disclosure, in order to not change the HARQ process ID field in the DCI indication as much as possible, different manners may be adopted to scramble the DCI according to the type of the resource to be scheduled, so that when the terminal device receives the DCI, it may be determined, based on the scrambling manner of the DCI, whether the resource to be scheduled corresponding to the HARQ process ID indicated in the DCI corresponds to the CG or the DG.

For example, when the scheduling resource corresponding to the DG is indicated, the DCI may be scrambled by using a first type of scrambling method, where the first type of scrambling method may be a Radio Network Temporary Identifier (RNTI) or a Modulation Coding Scheme (MCS) RNTI of a cell (C).

Alternatively, when the CG is instructed to retransmit the corresponding scheduling resource, a second type of scrambling scheme may be used, for example, a Configured Scheduling (CS) RNTI is used to scramble the DCI, which is not limited in this disclosure.

It should be noted that the above-mentioned first type scrambling manner and second type scrambling manner are only examples, and the present disclosure does not specifically limit the first type scrambling manner and the second type scrambling manner, and only needs to adopt different scrambling manners when scheduling resources corresponding to CG retransmission and scheduling resources corresponding to DG.

And step 44, determining the value of the HARQ process ID corresponding to the resource to be scheduled according to the scrambling mode and the value of the HARQ process ID contained in the DCI.

Optionally, when the scrambling mode is the first type, determining that a value of an HARQ process ID corresponding to the resource to be scheduled is a value of an HARQ process ID included in the DCI, where the HARQ process ID corresponding to the resource to be scheduled is the first HARQ process ID;

That is, if the scrambling scheme is of the first type, it indicates that the currently scheduled resource is a resource corresponding to DG, and at this time, the HARQ process ID included in the DCI may be determined as the HARQ process ID of the resource to be scheduled corresponding to DG, and if the scrambling scheme is of the second type, it indicates that the currently scheduled resource is a resource corresponding to CG retransmission, and at this time, the sum of the HARQ process ID included in the DCI and the first number may be determined as the HARQ process ID of the resource to be scheduled corresponding to CG retransmission.

For example, if the terminal device determines that the DCI scrambling scheme is the first type and the HARQ process ID included in the DCI is 15 after parsing the DCI, it may determine that the currently scheduled resource is the resource whose HARQ process ID corresponding to the DG is 15.

Or, if the first number is 32, after the terminal device analyzes the DCI, it determines that the DCI scrambling scheme is the second type and the HARQ process ID included in the DCI is 15, it may determine that the currently scheduled resource is a resource whose HARQ process ID corresponding to the CG is 47.

In the disclosure, the terminal device first receives HARQ process IDs corresponding to the indication CG and DG, and then, after receiving the DCI, determines the HARQ process ID corresponding to the resource to be scheduled according to the scrambling method of the DCI and the HARQ process ID contained therein. Therefore, under the condition of not changing the DCI signaling structure, the flexible configuration and scheduling of the HARQ process IDs corresponding to the CG and the DG are realized.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a terminal device. As shown in fig. 5, the method may include, but is not limited to, the following steps:

step 51, receiving first indication information, where the first indication information is used to indicate a first HARQ process ID of a first number of DGs and a second HARQ process ID of a second number of CGs, where the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of the indicated HARQ process IDs in the DCI.

The specific implementation form of step 51 may refer to detailed steps in other embodiments in the present disclosure, and details are not described here.

And step 52, receiving third indication information, where the third indication information is used to indicate the HARQ process ID to be activated or deactivated.

In this disclosure, after the network device configures the HARQ process IDs for the CG and the DG, the network device may activate or deactivate a part of the HARQ process IDs through the independent indication information.

Optionally, the third indication information may be Media Access Control (MAC) Control Element (CE) signaling, which is not limited in this disclosure.

Generally, the number of HARQ process IDs that the network device can activate at most at a time may be determined according to the capability of the terminal device. For example, the terminal device may support 16 HARQ buffer queues at most, and the number of HARQ process IDs that the network device can activate at most at a time may be 16. Or, the terminal device may support 32 HARQ buffer queues at most, the number of HARQ process IDs that the network device can activate at most at a time may be 32, and so on.

Optionally, the terminal device may first reserve the buffer queue corresponding to the DG when not receiving the third indication information, that is, the terminal device may first generate the buffer queues corresponding to the first number of HARQ process IDs when not receiving the third indication information. And then, under the condition of receiving the third indication information, adjusting the HARQ process ID corresponding to the queue according to the indication information.

For example, if the first number of HARQ process IDs corresponding to DG are HARQ process ID #0 to HARQ process ID #31, the terminal device can reserve the buffers corresponding to HARQ process ID #0 to HARQ process ID #31, respectively, when the terminal device does not receive the indication information. Therefore, HARQ processes which can be supported by the terminal equipment to the maximum extent all have corresponding buffers, and the method can be used for caching and combining data received by each HARQ process ID buffer.

Or, the third indication information may include the to-be-activated HARQ process ID and the deactivated HARQ process ID, so that the terminal device may empty the buffer queue corresponding to the deactivated HARQ process ID indicated in the third indication information and generate the buffer queue corresponding to the activated HARQ process ID indicated in the third indication information, when receiving the third indication information.

In this disclosure, the terminal device first receives the HARQ process IDs corresponding to the CG and the DG, and then activates or deactivates the HARQ process IDs according to the received indication information. Therefore, under the condition of not changing the indication signaling structure, the flexible configuration, activation or deactivation of the HARQ process ID corresponding to the CG and the DG respectively is realized.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a terminal device. As shown in fig. 6, the method may include, but is not limited to, the following steps:

step 61, receiving first indication information, where the first indication information is used to indicate a first HARQ process ID of a first number of DGs and a second HARQ process ID of a second number of CGs, the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of the indicated HARQ process IDs in the DCI.

The specific implementation form of step 61 may refer to the detailed steps in other embodiments in this disclosure, and details are not described here.

And step 62, generating a Type 3Type3HARQ feedback codebook according to the demodulation result of the buffer queue corresponding to each HARQ process ID.

And step 63, sending the Type3HARQ feedback codebook.

In a communication system, when a terminal device and a network device cannot determine a corresponding feedback time slot based on a transmission time slot in which an HARQ process is located, a Type3HARQ feedback codebook needs to be used for feedback. In this disclosure, since the HARQ process ID number corresponding to the DG and the CG and the maximum HARQ buffer number that is greater than the terminal device support, the Type3HARQ feedback codebook needs to be enhanced to ensure that the Type3HARQ feedback codebook can indicate the demodulation results of all HARQ processes at the same time.

Optionally, the Type3HARQ feedback codebook may include a sum of the second number and the first number. That is, the bits of the Type3HARQ feedback codebook may be extended, so that the Type3HARQ feedback codebook may contain the sum of the second number and the first number of demodulation results.

Alternatively, the feedback results in the Type3HARQ feedback codebook may be arranged in a fixed HARQ process ID order. For example, the sequence of the HARQ process IDs corresponding to the feedback results in the Type3HARQ feedback codebook is from small to large, or the sequence of the HARQ process IDs corresponding to the feedback results in the Type3HARQ feedback codebook is from large to small.

For example, Type3HARQ feedback codebook can be used to indicate the demodulation results of 32 HARQ processes, and the demodulation results of the 32 HARQ processes are arranged from large to small according to the HARQ process ID. After demodulating the data in the current 32 buffers, the terminal device may arrange the 32 demodulation results according to the HARQ process IDs corresponding to the current 32 buffers from large to small according to the HARQ process IDs. Then, the network device may sequentially determine whether data transmission corresponding to the current 32 HARQ process IDs is successful according to each demodulation result in the received Type3HARQ feedback codebook.

It can be understood that the HARQ process ID in the Type3HARQ feedback codebook may be an HARQ process ID corresponding to CG, an HARQ process ID corresponding to DG, or an HARQ process ID corresponding to DG as well as CG.

In the present disclosure, the terminal device first receives HARQ process IDs corresponding to the CG and DG, and then may generate and transmit a Type3HARQ feedback codebook according to a demodulation result of the buffer queue corresponding to each HARQ process ID. Therefore, on the basis of realizing flexible configuration of HARQ process IDs corresponding to CG and DG, reliable feedback of demodulation results of the cache queues corresponding to each HARQ process ID is realized.

Referring to fig. 7, fig. 7 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a network device. As shown in fig. 7, the method may include, but is not limited to, the following steps:

step 71, sending first indication information, where the first indication information is used to indicate a first hybrid automatic repeat request HARQ process number process ID of a first number of dynamic scheduling DGs and a second HARQ process ID of a second number of configuration grants CG, where the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of an indicated HARQ process ID in downlink control information DCI.

It is understood that in NR and TN networks, DG and CG may multiplex the same HARQ process ID pool. However, in the NTN network, if DG and CG still multiplex HARQ process ID pool, the product of RTT and max _ re-trans _ num is greater than the SPS PDSCH period, which results in excessive HARQ process IDs that the CG needs to allocate, and further results in less HARQ process IDs available for DG, thereby reducing the flexibility of DG selecting feedback enabled HARQ process IDs or feedback disabled HARQ process IDs. In this disclosure, the network device configures HARQ process IDs for DG and CG, respectively, so that the CG and the DG can flexibly configure feedback enabled HARQ process ID and feedback enabled HARQ process ID.

For example, if the first number is 32 and the second number is 32, the first HARQ process ID of 32 DGs may be 0 to 31, and the second HARQ process ID of 32 CGs may be 32 to 63. If i is 15, the 15 th second HARQ process ID corresponding to the CG may be the 15 th HARQ process ID +32 corresponding to the DG, that is, the 15 th HARQ process ID corresponding to the CG has the following value: 15+32 ═ 47.

Optionally, the network device may send the first indication information to the terminal device through RRC signaling.

By implementing the embodiment of the present disclosure, the network device sends the first indication information to the terminal device, so that the terminal device determines the HARQ process ID corresponding to the first number of DGs and the second HARQ process ID corresponding to the second number of CGs. Therefore, the network device can flexibly configure the feedback enabled HARQ process ID and the feedback disabled HARQ process ID in the CG and the DG by configuring the HARQ process ID corresponding to the CG and the DG for the terminal device respectively.

Referring to fig. 8, fig. 8 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a network device. As shown in fig. 8, the method may include, but is not limited to, the following steps:

step 81, sending first indication information, where the first indication information is used to indicate HARQ process IDs of a first number of DGs and second HARQ process IDs of a second number of CGs, the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of the indicated HARQ process IDs in the DCI.

The specific implementation form of step 81 may refer to the detailed steps in other embodiments in this disclosure, and is not described in detail here.

And step 82, sending second indication information, wherein the second indication information is used for indicating that the first HARQ process ID and the second HARQ process ID are the feedback-enabled HARQ process ID or the feedback-disabled HARQ process ID.

By implementing the embodiment of the present disclosure, the network device sends the first indication information to the terminal device, so that the terminal device determines the first HARQ process ID of the first number of DGs and the second HARQ process ID of the second number of CGs, and then sends the second indication information to the terminal device, so that the terminal device determines that the first HARQ process ID and the second HARQ process ID are the feedback-enabled HARQ process ID or the feedback-disabled HARQ process ID. Therefore, the feedback enabling HARQ process ID and the feedback disabling HARQ process ID in CG and DG are flexibly configured for the terminal equipment.

Referring to fig. 9, fig. 9 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a network device. As shown in fig. 9, the method may include, but is not limited to, the following steps:

step 91, transmitting first indication information, wherein the first indication information is used to indicate HARQ process IDs of a first number of DGs and second HARQ process IDs of a second number of CGs, the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and a sum of the first number and the second number is greater than a maximum value of the indicated HARQ process IDs in the DCI.

The specific implementation form of step 91 may refer to detailed steps in other embodiments in the present disclosure, and details are not described here.

And step 92, determining a value of the HARQ process ID corresponding to the resource to be scheduled, wherein the value of the HARQ process ID corresponding to the resource to be scheduled is smaller than the sum of the first number and the second number.

The resource to be scheduled may be a resource corresponding to CG retransmission or a resource corresponding to DG, and a value of the HARQ process ID corresponding to the resource to be scheduled is smaller than a sum of the first number and the second number.

And step 93, determining a scrambling mode corresponding to the DCI and a value of the HARQ process ID contained in the DCI according to the value of the HARQ process ID corresponding to the resource to be scheduled, wherein the value of the HARQ process ID contained in the DCI is smaller than the first number or the second number.

Optionally, when the value of the HARQ process ID corresponding to the resource to be scheduled is smaller than the first number, it is determined that the scrambling mode is the first type, and the value of the HARQ process ID included in the DCI is the value of the HARQ process ID corresponding to the resource to be scheduled, and the HARQ process ID corresponding to the resource to be scheduled is the first HARQ process ID.

Or, when the value of the HARQ process ID corresponding to the resource to be scheduled is greater than or equal to the first number, determining that the scrambling mode is the second type, and the value of the HARQ process ID included in the DCI is equal to the value of the HARQ process ID corresponding to the resource to be scheduled, which is the second HARQ process ID — the first number.

For example, if the first number is 32, the network device schedules the resource corresponding to the DG when the value of the HARQ process ID corresponding to the resource to be scheduled is less than 32, so that the DCI may be scrambled by using a first type of scrambling method, where the first type of scrambling method may be C-RNTI or MCS-RNTI.

Or, when the value of the HARQ process ID corresponding to the resource to be scheduled is greater than 32, and the network device schedules the CG to retransmit the corresponding resource, a second type of scrambling method may be adopted, for example, the CS-RNTI is adopted to scramble the DCI, which is not limited in this disclosure.

And step 94, generating the DCI according to the value of the HARQ process ID and the scrambling mode contained in the DCI.

Step 95, transmitting the DCI.

In the disclosure, the network device first sends HARQ process IDs corresponding to the CG and DG to the terminal device, then determines a DCI scrambling method and the HARQ process ID contained therein according to a value of the HARQ process ID corresponding to a resource to be scheduled, and finally sends the DCI to the terminal device. Therefore, under the condition of not changing the DCI signaling structure, the flexible configuration and scheduling of the HARQ process IDs corresponding to the CG and the DG are realized.

Referring to fig. 10, fig. 10 is a flowchart illustrating a method for determining a harq process number according to an embodiment of the present disclosure, where the method is executed by a network device. As shown in fig. 10, the method may include, but is not limited to, the following steps:

And 102, sending third indication information, wherein the third indication information is used for indicating the HARQ process ID to be activated or deactivated.

In the disclosure, the network device first indicates the HARQ process IDs corresponding to the CG and the DG, respectively, to the terminal device, and then sends third indication information to the terminal device to indicate the terminal device to activate or deactivate the HARQ process ID. Therefore, under the condition of not changing the indication signaling structure, the flexible configuration, activation or deactivation of the HARQ process ID corresponding to the CG and the DG respectively is realized.

And step 112, receiving a Type 3Type3HARQ feedback codebook.

And step 113, determining the demodulation result of the resource corresponding to each HARQ process ID according to the Type3HARQ feedback codebook.
