It can be understood that the communication system described in the embodiments of the present disclosure is to illustrate the technical solutions of the embodiments of the present disclosure more clearly, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. With the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

The method and device for determining the HARQ process number provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a method for determining a HARQ process number provided by an embodiment of the present disclosure, and the method is executed by a terminal device. As shown in Figure 2, the method may include but not limited to the following steps:

Step 21, receiving the first indication information, wherein the first indication information is used to indicate the first hybrid automatic repeat request HARQ process ID of the first number of dynamic scheduling DGs and the second number of configuration authorization CGs of the second number HARQ process ID, the first number of first HARQ process IDs and the second number of second HARQ process IDs do not overlap, and the sum of the first number and the second number is greater than the maximum HARQ process ID that can be indicated in the downlink control information DCI value.

It can be understood that in NR network and TN network, DG and CG can reuse the same HARQ process ID pool pool. However, in the NTN network, if the DG and CG still reuse the HARQ process ID pool, the product of RTT and max_re-trans_num will be greater than the SPS PDSCH cycle, resulting in too many HARQ process IDs for the CG to be allocated, which in turn will cause the available DG The number of HARQ process IDs decreases, which reduces the flexibility of DG to select feedback enabled HARQ process IDs or feedback disabled HARQ process IDs. In this disclosure, HARQ process IDs are configured for DG and CG respectively, so that feedback enabled HARQ process IDs and feedback disabled HARQ process IDs in CG and DG can be flexibly configured.

Wherein, the value of the first number and the value of the second number may be any value less than or equal to the capability of the terminal device, that is, the second number and the first number may be any value 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 value of the first number can be 16, 20, 32, etc., and the value of the second number can be 15, 20, 32, etc. The present disclosure does not limit this.

It should be noted that the value of the second quantity may be the same as or different from the value of the first quantity, which is not limited in the present disclosure.

Optionally, the network device may determine the maximum value of the HARQ process ID that can be indicated in the DCI according to the capability of the terminal device. 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 this disclosure, in order to solve the problem that CG and DG cannot reuse the HARQ process ID pool in the NTN network, multiple HARQ process IDs can be configured for CG and DG separately, in order to ensure that the HARQ process IDs configured for CG and DG are as far as possible The ID can meet the requirements of CG and DG. In this disclosure, the sum of the first number and the second number can be set to be greater than the maximum value of the HARQ process ID that can be indicated in the DCI.

Optionally, in order not to change the format of the DCI signaling as much as possible, in this disclosure, the first number and the second number can be set to the same value, that is, the i-th second HARQ process ID = the i-th first HARQ process ID process ID+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 HARQprocess IDs of the 32 DGs may be 0-31, and the second HARQprocess IDs of the 32 CGs may be 32-63. If i=15, the 15th second HARQ process ID corresponding to CG can be the 15th HARQ process ID+32 corresponding to DG, that is, the value of the 15th HARQ process ID corresponding to CG is: 15+32= 47.

It should be noted that the above examples are simply illustrations, and cannot be used as specific limitations on the value of the first number, the value of the second number, and the value of i in the present disclosure.

Usually, the initial transmission resources of CG are configured by RRC. At this time, the terminal device can determine the HARQ process ID of the initial SPS PDSCH transmission according to the formula according to the RRC parameters and the time unit where the SPSPDSCH is located. Without changing the original formula, the HARQ process ID = value calculated by the original formula + first quantity.

The retransmission resources of CG are scheduled by DCI. At this time, the terminal device can determine the retransmission HARQ process ID of SPSPDSCH according to the scrambling method of DCI and the HARQ process ID value indicated in DCI. HARQ process ID = HARQ process ID indication value in DCI + first quantity. Wherein, the relationship between the DCI scrambling mode and the HARQ process ID can refer to the detailed description of other embodiments of the present disclosure, and will not be repeated here.

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

By implementing the embodiments of the present disclosure, the terminal device can 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. Thus, by configuring the HARQ process IDs corresponding to the CG and DG for the terminal equipment, it is possible to flexibly configure the feedback enabled HARQ process ID and the feedback disabled HARQ process ID in the CG and DG.

Please refer to FIG. 3 . FIG. 3 is a schematic flowchart of a method for determining a HARQ process number provided by an embodiment of the present disclosure, and the method is executed by a terminal device. As shown in Figure 3, the method may include but not limited to the following steps:

Step 31, receiving the first indication information, wherein the first indication information is used to indicate the first HARQ process ID of the first number of DGs and the second HARQ process ID of the second number of CGs, and the first number of first HARQ process IDs The process ID does not coincide with the second number of second HARQ process IDs, and the sum of the first number and the second number is greater than the maximum value of the HARQ process ID that can be indicated in the DCI.

Wherein, for the specific implementation form of step 31, reference may be made to the detailed steps in other embodiments of the present disclosure, and details will not be repeated here.

Step 32: Receive second indication information, where the second indication information is used to indicate that the first HARQ process ID and the second HARQ process ID are feedback enabling HARQ process IDs or feedback disabling HARQ process IDs.

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

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

It should be noted that the second indication information in this embodiment may be the same as or different from the first indication information. That is, the network device can 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 through one RRC signaling. Can HARQ process ID or feedback disable HARQ process ID. Alternatively, the network device may also indicate the first HARQ process ID of the first number of DGs through one RRC signaling, and the second HARQ process ID of the second number of CGs; and then indicate the first HARQ process ID and the second number of CGs through another RRC signaling. The second HARQ process ID is the feedback enabling HARQ process ID or the feedback disabling HARQ process ID. The present disclosure does not limit this.

By implementing the embodiments of the present disclosure, the terminal device determines the first hybrid automatic repeat request HARQ process ID of the first number of dynamic scheduling DGs and the second number of configuration authorization CGs by receiving the first indication information sent by the network device The second HARQ process ID, and then according to the received second indication information, determine that the first HARQ process ID and the second HARQ process ID are the feedback enabling HARQ process ID or the feedback disabling HARQ process ID. Thus, it is realized to flexibly configure the feedback enabling HARQ process ID and the feedback disabling HARQ process ID in the CG and DG for the terminal equipment.

Please refer to FIG. 4 . FIG. 4 is a schematic flowchart of a method for determining a HARQ process number provided by an embodiment of the present disclosure, and the method is executed by a terminal device. As shown in Figure 4, the method may include but not limited to the following steps:

Step 41, receiving the first indication information, wherein the first indication information is used to indicate the first HARQ process ID of the first number of DGs and the second HARQ process ID of the second number of CGs, and the first number of first HARQ process IDs The process ID does not coincide with the second number of second HARQ process IDs, and the sum of the first number and the second number is greater than the maximum value of the HARQ process ID that can be indicated in the DCI.

Wherein, for the specific implementation form of step 41, reference may be made to the detailed steps in other embodiments of the present disclosure, which will not be described in detail here.

Step 42, receiving downlink control information DCI, wherein the DCI is used to indicate the 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 less than the first number and the second number of and.

Usually, the network device can determine the initial transmission HARQ process ID of the SPS PDSCH according to the RRC parameters and the time unit where the PDSCH is located. When an error occurs in the initial transmission, the retransmission HARQ process ID of the SPS PDSCH can be indicated by the DCI, and the retransmission HARQ process ID indicated in the DCI is the same as the HARQ process ID of the SPS PDSCH that was initially transmitted incorrectly. That is, the network device can indicate to the terminal device the value of the HARQ process ID corresponding to the resource to be scheduled through the DCI.

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

Step 43: Decode the DCI to determine the value of the HARQ process ID included in the DCI and the corresponding scrambling method, wherein the value of the HARQ process ID included in the DCI is smaller than the first number or the second number.

In this disclosure, in order not to change the HARQ process ID field in the DCI indication as much as possible, different methods can be used to scramble the DCI according to the type of resource to be scheduled, so that when the terminal device receives the DCI, it can scramble the DCI based on the DCI scrambling mode, determine 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 indicating the scheduling resource corresponding to the DG, the first type of scrambling method may be used to scramble the DCI, wherein the first type of scrambling method may be a temporary cell (cell, C) wireless network Identifier (Radio Network Temporary Identifier, RNTI) or modulation coding scheme (modulcation coding scheme, MCS) RNTI.

Or, when instructing the CG to retransmit the corresponding scheduling resource, the second type of scrambling method may be used, for example, a configured scheduling (configured scheduling, CS) RNTI is used to scramble the DCI, which is not limited in the present disclosure.

It should be noted that the above-mentioned first type of scrambling method and the second type of scrambling method are only examples, and the present disclosure does not specifically limit the first type of scrambling method and the second type of scrambling method. Different scrambling methods may be used when scheduling resources corresponding to CG retransmission and when scheduling resources corresponding to DG.

Step 44: Determine the value of the HARQ process ID corresponding to the resource to be scheduled according to the scrambling method and the value of the HARQ process ID included in the DCI.

Optionally, when the scrambling method is the first type, determine the value of the HARQ process ID corresponding to the resource to be scheduled = the value of the HARQ process ID contained in the DCI, and the HARQ process ID corresponding to the resource to be scheduled is the first HARQ process ID;

Or, when the scrambling mode is the second type, determine the value of the HARQ process ID corresponding to the resource to be scheduled = the value of the HARQ process ID contained in the DCI + the first quantity, and the HARQ process ID corresponding to the resource to be scheduled The process ID is the second HARQ process ID.

That is to say, if the scrambling method is the first type, it means that the currently scheduled resource is the resource corresponding to the DG. At this time, the HARQ process ID contained in the DCI can be determined as the HARQ process ID of the resource to be scheduled corresponding to the DG. process ID, if the scrambling method is the second type, it means that the currently scheduled resource is the resource corresponding to the CG retransmission. At this time, the sum of the HARQ process ID contained in the DCI and the first number can be determined as the CG retransmission Pass the HARQ process ID of the corresponding resource to be scheduled.

For example, if the terminal device analyzes the DCI and determines that the DCI scrambling method is the first type and the HARQ process ID contained in the DCI is 15, then it can be determined that the currently scheduled resource is the HARQ process ID corresponding to the DG is 15 resource.

Or, if the first number is 32, after the terminal device analyzes the DCI, it determines that the DCI scrambling mode is the second type, and the HARQ process ID contained in the DCI is 15, then it can be determined that the currently scheduled resource is the HARQ process corresponding to the CG Resource with ID 47.

In this disclosure, the terminal device first receives the HARQ process IDs used to indicate the respective correspondences of CG and DG, and then, after receiving the DCI, it can determine the resources to be scheduled according to the scrambling method of the DCI and the HARQ process ID contained therein The corresponding HARQ process ID. Thus, without changing the DCI signaling structure, the flexible configuration and scheduling of the HARQ process IDs corresponding to the CG and DG are realized.

Please refer to FIG. 5 . FIG. 5 is a schematic flowchart of a method for determining a HARQ process number provided by an embodiment of the present disclosure, and the method is executed by a terminal device. As shown in Figure 5, the method may include but not limited to the following steps:

Step 51, receiving the first indication information, wherein the first indication information is used to indicate the first HARQ process ID of the first number of DGs and the second HARQ process ID of the second number of CGs, and the first number of first HARQ process IDs The process ID does not coincide with the second number of second HARQ process IDs, and the sum of the first number and the second number is greater than the maximum value of the HARQ process ID that can be indicated in the DCI.

Wherein, for the specific implementation form of step 51, reference may be made to the detailed steps in other embodiments of the present disclosure, and details are not repeated here.

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 configuring HARQ process IDs for the CG and DG respectively, the network device can activate or deactivate part of the HARQ process IDs through independent indication information.

Optionally, the third indication information may be media access control (Media access control, MAC) control element (control element, CE) signaling, which is not limited in the present disclosure.

Usually, the maximum number of HARQ process IDs that a network device can activate each time can be determined according to the capability of the terminal device. For example, a terminal device can support up to 16 HARQ buffer queues, and a network device can activate a maximum of 16 HARQ process IDs each time. Alternatively, the terminal device can support up to 32 HARQ buffer queues, and the maximum number of HARQ process IDs that can be activated by the network device each time can be 32 and so on.

Optionally, if the terminal device does not receive the third indication information, it may first reserve the buffer queue corresponding to the DG, that is, if the terminal device does not receive the third indication information, it may first generate the first number of The cache queue corresponding to the HARQ process ID. Afterwards, when the third indication information is received, the HARQ process ID corresponding to the queue is adjusted according to the indication information.

For example, the first number of HARQ process IDs corresponding to the DG are HARQ process ID#0~HARQ process ID#31, and the terminal device can reserve the HARQ process ID first without receiving the instruction information. #0～HARQ process ID#31 correspond to the buffer respectively. To ensure that the maximum HARQ process supported by the terminal device has a corresponding buffer, which can be used to cache and merge the data received by each HARQ process ID buffer.

Alternatively, the third indication information may include both the HARQ process ID to be activated and the deactivation HARQ process ID, then the terminal device may clear the HARQ process ID indicated in the third indication information upon receiving the third indication information. Deactivate the cache queue corresponding to the activated HARQ process ID, and generate the cache queue corresponding to the activated HARQ process ID indicated in the third indication information.

In the present disclosure, the terminal device first receives the HARQ process IDs used to indicate the respective correspondences of the CG and the DG, and then activates or deactivates the HARQ process IDs according to the received indication information. Thus, without changing the indication signaling structure, the flexible configuration, activation or deactivation of the HARQ process IDs respectively corresponding to the CG and the DG is realized.

Please refer to FIG. 6 . FIG. 6 is a schematic flowchart of a method for determining a HARQ process number provided by an embodiment of the present disclosure, and the method is executed by a terminal device. As shown in Figure 6, the method may include but not limited to the following steps:

Step 61, receiving the first indication information, wherein the first indication information is used to indicate the first HARQ process ID of the first number of DGs and the second HARQ process ID of the second number of CGs, and the first number of first HARQ process IDs The process ID does not coincide with the second number of second HARQ process IDs, and the sum of the first number and the second number is greater than the maximum value of the HARQ process ID that can be indicated in the DCI.

Wherein, for the specific implementation form of step 61, reference may be made to the detailed steps in other embodiments of the present disclosure, and details are not repeated here.

Step 62: Generate a Type 3 Type3 HARQ feedback codebook according to the demodulation result of the cache queue corresponding to each HARQ process ID.

Step 63, sending the Type3 HARQ feedback codebook.

In the communication system, when the terminal device and the network device cannot determine the corresponding feedback time slot based on the transmission time slot where the HARQ process is located, it is necessary to use the Type3 HARQ feedback codebook for feedback. In this disclosure, since the number of HARQ process IDs corresponding to DG and CG is greater than the maximum number of HARQ buffers supported by the terminal device, it is necessary to enhance the Type3 HARQ feedback codebook to ensure that the Type3 HARQ feedback codebook can simultaneously indicate all HARQ The demodulation result of the process.

Optionally, the Type3 HARQ feedback codebook may include the demodulation results of the second quantity and the first quantity. That is, the bits of the Type3 HARQ feedback codebook can be extended so that the Type3 HARQ feedback codebook can include the sum of the second number and the first number of demodulation results.

Alternatively, the feedback results in the Type3 HARQ feedback codebook can also be arranged in a fixed order of HARQ process IDs. For example, the order of the HARQ process IDs corresponding to the feedback results in the Type3 HARQ feedback codebook is from small to large, or the order of the HARQ process IDs corresponding to the feedback results in the Type3 HARQ feedback codebook is from large to small.

For example, the Type3 HARQ 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 in descending order according to the HARQ process ID. After the terminal device demodulates the data in the current 32 buffers, it can arrange the 32 demodulation results according to the HARQ process ID from large to small according to the HARQ process IDs corresponding to the current 32 buffers. After that, the network device can sequentially determine whether the data transmission corresponding to the current 32 HARQ process IDs is successful according to each demodulation result in the received Type3 HARQ feedback codebook.

It is understandable that the HARQ process ID in the Type3 HARQ feedback codebook can be the HARQ process ID corresponding to CG, or the HARQ process ID corresponding to DG, or it can include both the HARQ process ID corresponding to CG and DG The corresponding HARQ process ID.

In this disclosure, the terminal device first receives the HARQ process IDs used to indicate the respective correspondences of the CG and DG, and then generates and sends the Type3 HARQ feedback codebook according to the demodulation results of the buffer queues corresponding to each HARQ process ID. Thus, on the basis of realizing the flexible configuration of the HARQ process IDs corresponding to the CG and DG respectively, the reliable feedback of the demodulation results of the buffer queues corresponding to each HARQ process ID is realized.

Please refer to FIG. 7 . FIG. 7 is a schematic flowchart of a method for determining a HARQ process number provided by an embodiment of the present disclosure, and the method is executed by a network device. As shown in Figure 7, the method may include but not limited to the following steps:

It can be understood that in NR network and TN network, DG and CG can reuse the same HARQ process ID pool pool. However, in the NTN network, if the DG and CG still reuse the HARQ process ID pool, because the product of RTT and max_re-trans_num is greater than the SPS PDSCH cycle, the CG needs to allocate too many HARQ process IDs, which will lead to the available DG The number of HARQ process IDs decreases, which reduces the flexibility of DG to select 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 feedback enabled HARQ process ID and feedback enabled HARQ process ID in CG and DG can be flexibly configured.

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

The retransmission resources of CG are scheduled by DCI. At this time, the terminal device can determine the retransmission HARQ process ID of SPSPDSCH according to the scrambling method of DCI and the HARQ processID value indicated in DCI. HARQ process ID = HARQ processID indication value in DCI + first quantity. Wherein, the relationship between the DCI scrambling mode and the HARQ process ID can refer to the detailed description of other embodiments of the present disclosure, and will not be repeated here.

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

Thus, the network device can flexibly configure the feedback enabled HARQ process ID and feedback disabled HARQ process ID in the CG and DG by respectively configuring the HARQ process ID corresponding to the CG and DG for the terminal device.
