Abstract
Description
Technical Field
[0001] This disclosure relates to the field of communications, and in particular to HARQ-ACK information feedback methods, apparatus, and storage media. Background Technology
[0002] Current communication standards require terminals to provide corresponding HARQ-ACK (Hybrid Automatic Repeat Request-Acknowledge) feedback for each DL SPS (Downlink Semi-Persistent Scheduling). However, since the SPS cycle in Release 16 (R16) has been shortened to one time slot, feedback is more frequent. For TDD (Time Division Multiplexing) systems, a large number of unavailable uplink symbols may exist, potentially leaving insufficient resources for HARQ-ACK feedback. This can lead to a significant amount of dropped SPS HARQ-ACKs. Summary of the Invention

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0094] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0095] Release 17 (R17) provides a feedback method for SPS HARQ-ACK information in TDD communication systems. The HARQ-ACK information corresponding to the SPS PDSCH is deferred to the next available PUCCH (Physical Uplink Control Channel) for feedback. For example... Figure 1 As shown, the HARQ-ACK information corresponding to the third SPS PDSCH can be delayed until the next available PUCCH for feedback.
[0096] However, there is no concrete solution yet for situations where HARQ-ACK messages corresponding to multiple SPS PDSCHs of different priorities need to be delayed simultaneously.
[0097] To address the aforementioned technical issues, this disclosure provides the following HARQ-ACK information feedback method.
[0098] The following section will first introduce the HARQ-ACK information feedback method provided in this publication from the perspective of the terminal side.
[0099] In this embodiment of the disclosure, the corresponding HARQ-ACK information feedback method can be determined based on different situations where the terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH.
[0100] In the first scenario, the terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH.
[0101] This disclosure provides a HARQ-ACK information feedback method, referring to... Figure 2 As shown, Figure 2 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a first terminal. The first terminal supports the reuse of HARQ-ACK information corresponding to SPSPDSCH. The method may include the following steps:
[0102] In step 201, in response to determining the HARQ-ACK information corresponding to SPS PDSCH with different priorities of delayed feedback, the HARQ-ACK information corresponding to the SPS PDSCH with different priorities is multiplexed to obtain the target HARQ-ACK information.
[0103] In this embodiment of the disclosure, the first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine the feedback resources corresponding to SPS PDSCH of different priorities.
[0104] In step 202, a first target physical uplink control channel (PUCCH) resource is determined for feeding back the target HARQ-ACK information.
[0105] In step 203, the target HARQ-ACK information is fed back to the base station through the first target PUCCH resource.
[0106] In the above embodiments, HARQ-ACK information corresponding to SPS PDSCHs of different priorities can be multiplexed to obtain target HARQ-ACK information. Then, the first terminal determines a first target PUCCH resource to feed back the target HARQ-ACK information, and uses this first target PUCCH resource to feed back the target HARQ-ACK information to the base station. This disclosure provides a multiplexing method for HARQ-ACK information corresponding to SPS PDSCHs of different priorities and a method for obtaining the feedback target HARQ-ACK information after multiplexing, specifically for first terminals supporting the multiplexing of HARQ-ACK information corresponding to SPS PDSCHs. This improves the reliability of HARQ-ACK information feedback, thereby enhancing the reliability of the TDD communication system.
[0107] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 3A As shown, Figure 3A This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a first terminal. The first terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0108] In step 301, in response to determining the HARQ-ACK information corresponding to SPS PDSCH with different priorities of delayed feedback, the HARQ-ACK information corresponding to the SPS PDSCH with different priorities is multiplexed to obtain the target HARQ-ACK information.
[0109] In this embodiment of the disclosure, the first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine the feedback resources corresponding to SPS PDSCH of different priorities.
[0110] In step 302, in response to determining that the first PUCCH resource indicated by the first downlink control information (DCI) is an available resource, the first PUCCH resource is used as the first target PUCCH resource.
[0111] In this embodiment of the disclosure, the first DCI (Downlink Control Information) refers to the DCI used to activate the SPS PDSCH with the highest priority among the different priorities, which is pre-configured for the first terminal. The first priority is higher than the second priority among the different priorities. That is, the first DCI is the DCI used to activate the higher priority SPS PDSCH among the different priorities.
[0112] The PRI (PUCCH Resource Indicator) field in the first DCI indicates the PUCCH resource used to feed back HARQ-ACK information corresponding to the SPS PDSCH activated by the first DCI. If the first terminal determines that the first PUCCH indicated by the first DCI used to activate the high-priority SPS PDSCH is an available resource, it will use the first PUCCH as the first target PUCCH resource for feeding back the target HARQ-ACK information.
[0113] In step 303, the target HARQ-ACK information is fed back to the base station through the first target PUCCH resource.
[0114] In the above embodiments, when the first terminal determines the HARQ-ACK information corresponding to SPS PDSCHs with different priorities for delayed feedback, it can prioritize using the first PUCCH resource, which belongs to the available resource and is used to activate the higher-priority SPS PDSCH, as the first target PUCCH resource for feeding back the target HARQ-ACK information. This improves the reliability of HARQ-ACK information feedback, thereby improving the reliability of the TDD communication system.
[0115] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 3B As shown, Figure 3B This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a first terminal. The first terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0116] In step 301', in response to determining the HARQ-ACK information corresponding to the SPS PDSCH with different priorities of delayed feedback, the HARQ-ACK information corresponding to the SPS PDSCH with different priorities is multiplexed to obtain the target HARQ-ACK information.
[0117] In this embodiment of the disclosure, the first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine the feedback resources corresponding to SPS PDSCH of different priorities.
[0118] In step 302', in response to determining that the second PUCCH resource in the first PUCCH resource pool corresponding to the first priority SPS PDSCH is an available resource, the second PUCCH resource is used as the first target PUCCH resource.
[0119] In this embodiment, the first priority is the highest priority among different priorities. The first terminal prioritizes searching for available resources in the first PUCCH resource corresponding to the high-priority SPS PDSCH. If the second PUCCH resource in the first PUCCH resource pool is an available resource, then the first terminal can use the second PUCCH resource as the first target PUCCH resource for feeding back the target HARQ-ACK information.
[0120] In step 303', the target HARQ-ACK information is fed back to the base station through the first target PUCCH resource.
[0121] In the above embodiments, when the first terminal determines the HARQ-ACK information corresponding to SPS PDSCHs with different priorities for delayed feedback, it can prioritize searching for available resources in the first PUCCH resource corresponding to the high-priority SPS PDSCH, thereby determining the first target PUCCH resource for feedback of the target HARQ-ACK information. This improves the reliability of HARQ-ACK information feedback, thereby improving the reliability of the TDD communication system.
[0122] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 4A As shown, Figure 4A This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a first terminal. The first terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0123] In step 401, in response to determining the HARQ-ACK information corresponding to the SPS PDSCH with different priorities of delayed feedback, the HARQ-ACK information corresponding to the SPS PDSCH with different priorities is multiplexed to obtain the target HARQ-ACK information.
[0124] In this embodiment of the disclosure, the first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine the feedback resources corresponding to SPS PDSCH of different priorities.
[0125] In step 402, if the first PUCCH resource is an unavailable resource and there is no available resource in the first PUCCH resource pool, in response to determining that the third PUCCH resource indicated by the second DCI is an available resource, the third PUCCH resource is used as the first target PUCCH resource.
[0126] In this embodiment of the disclosure, the first PUCCH resource is the PUCCH resource indicated by the first DCI. The first DCI is used to activate the SPS PDSCH with the first priority among the different priorities, which is pre-configured for the first terminal. The first priority is higher than the second priority among the different priorities. The first PUCCH resource pool is the PUCCH resource pool corresponding to the SPS PDSCH with the first priority. The second DCI is used to activate the SPS PDSCH with the second priority among the different priorities, which is pre-configured for the first terminal. That is, the second DCI is used to activate the lower priority SPS PDSCH among the different priorities.
[0127] If the first terminal determines that the first PUCCH resource is an unavailable resource and there are no available resources in the first PUCCH resource pool, it can determine whether the third PUCCH resource indicated by the second DCI is an available resource.
[0128] If the first terminal determines that the third PUCCH resource indicated by the second DCI is an available resource, then the third PUCCH resource can be used as the first target PUCCH resource for feeding back target HARQ-ACK information.
[0129] In step 403, the target HARQ-ACK information is fed back to the base station through the first target PUCCH resource.
[0130] In the above embodiments, when the first terminal determines the HARQ-ACK information corresponding to SPS PDSCHs with different priorities for delayed feedback, if there are no available resources in the PUCCH resources corresponding to the high-priority SPS PDSCH, it can use the third PUCCH resource, which belongs to the available resources and is indicated by the second DCI used to activate the low-priority SPS PDSCH, as the first target PUCCH resource for feeding back the target HARQ-ACK information. This improves the reliability of HARQ-ACK information feedback, thereby improving the reliability of the TDD communication system.
[0131] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 4B As shown, Figure 4B This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a first terminal. The first terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0132] In step 401', in response to determining the HARQ-ACK information corresponding to the SPS PDSCH with different priorities of delayed feedback, the HARQ-ACK information corresponding to the SPS PDSCH with different priorities is multiplexed to obtain the target HARQ-ACK information.
[0133] In this embodiment of the disclosure, the first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine the feedback resources corresponding to SPS PDSCH of different priorities.
[0134] In step 402', if the first PUCCH resource is an unavailable resource and there is no available resource in the first PUCCH resource pool, in response to determining that the fourth PUCCH resource in the second PUCCH resource pool corresponding to the second priority SPS PDSCH is an available resource, the fourth PUCCH resource is used as the first target PUCCH resource.
[0135] In this embodiment of the disclosure, the first PUCCH resource is the PUCCH resource indicated by the first DCI. The first DCI is a DCI used to activate the SPS PDSCH of the first priority among the different priorities pre-configured for the first terminal, where the first priority is higher than the second priority among the different priorities. The first PUCCH resource pool is the PUCCH resource pool corresponding to the SPS PDSCH of the first priority.
[0136] If the first terminal determines that the first PUCCH resource is unavailable and there are no available resources in the first PUCCH resource pool, it can search in the second PUCCH resource pool corresponding to the second priority SPS PDSCH. The second priority is the lowest priority among different priorities.
[0137] If the fourth PUCCH resource in the second PUCCH resource pool is an available resource, then the first terminal can use the fourth PUCCH resource as the first target PUCCH resource for feeding back the target HARQ-ACK information.
[0138] In step 403', the target HARQ-ACK information is fed back to the base station through the first target PUCCH resource.
[0139] In the above embodiments, when the first terminal determines the HARQ-ACK information corresponding to SPS PDSCHs with different priorities for delayed feedback, if there are no available resources in the PUCCH resources corresponding to the high-priority SPS PDSCH, it can search for available resources in the second PUCCH resources corresponding to the low-priority SPS PDSCH, thereby determining the first target PUCCH resource for feedback of the target HARQ-ACK information. This improves the reliability of HARQ-ACK information feedback, thereby improving the reliability of the TDD communication system.
[0140] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 5 As shown, Figure 5 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a first terminal. The first terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0141] In step 501, in response to determining the HARQ-ACK information corresponding to SPS PDSCH with different priorities of delayed feedback, the HARQ-ACK information corresponding to the second priority SPS PDSCH is appended to the HARQ-ACK information corresponding to the first priority SPS PDSCH to obtain the target HARQ-ACK information.
[0142] The first priority is higher than the second priority. The first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCHs of different priorities if the initial HARQ-ACK feedback resources corresponding to SPS PDSCHs of different priorities are unavailable. It can also determine the feedback resources corresponding to SPS PDSCHs of different priorities that are delayed in being fed back.
[0143] In step 502, a first target physical uplink control channel (PUCCH) resource is determined for feeding back the target HARQ-ACK information.
[0144] In step 503, the target HARQ-ACK information is fed back to the base station through the first target PUCCH resource.
[0145] In the above embodiments, the HARQ-ACK information corresponding to the low-priority SPSPDSCH can be appended to the HARQ-ACK information corresponding to the high-priority SPS PDSCH. This achieves the reuse of HARQ-ACK information corresponding to SPS PDSCH of different priorities, resulting in high availability.
[0146] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 6 As shown, Figure 6 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a first terminal. The first terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0147] In step 601, in response to determining the HARQ-ACK information corresponding to the SPS PDSCH with different priorities of delayed feedback, the HARQ-ACK information corresponding to the SPS PDSCH with different priorities is multiplexed to obtain the target HARQ-ACK information.
[0148] In this embodiment of the disclosure, the first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable. It can also determine the feedback resources corresponding to the delayed feedback of SPS PDSCH of different priorities. In step 602, a first target physical uplink control channel (PUCCH) resource for feeding back the target HARQ-ACK information is determined.
[0149] In step 603, in response to determining that the total number of bits occupied by the target HARQ-ACK information is greater than the maximum number of bits carried by the first target PUCCH resource, the corresponding HARQ-ACK information is discarded in ascending order of priority of SPS PDSCH until the total number of bits occupied by the target HARQ-ACK information is less than or equal to the maximum number of bits carried by the first target PUCCH resource.
[0150] In step 604, the target HARQ-ACK information is fed back to the base station through the first target PUCCH resource.
[0151] In the above embodiments, if the total number of bits occupied by the multiplexed target HARQ-ACK information is greater than the maximum number of bits carried by the first target PUCCH resource, the HARQ-ACK information corresponding to the low-priority SPS PDSCH can be discarded first, so that the multiplexed target HARQ-ACK information can be fed back through the first target PUCCH resource. This ensures the reliability of the feedback of the HARQ-ACK information corresponding to the high-priority SPS PDSCH, thereby improving the reliability of the TDD communication system.
[0152] In the second scenario, the terminal does not support the reuse of HARQ-ACK information corresponding to SPS PDSCH.
[0153] This disclosure provides a HARQ-ACK information feedback method, referring to... Figure 7 As shown, Figure 7 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a second terminal that does not support the reuse of HARQ-ACK information corresponding to SPSPDSCH. The method may include the following steps:
[0154] In step 701, in response to determining the HARQ-ACK information corresponding to SPS PDSCHs with different priorities for delayed feedback, different second target PUCCH resources for feeding back the HARQ-ACK information corresponding to SPS PDSCHs with different priorities are determined in descending order of the different priorities.
[0155] In this embodiment of the disclosure, the second terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine the feedback resources corresponding to SPS PDSCH of different priorities.
[0156] In step 702, the HARQ-ACK information corresponding to the SPSPDSCH of different priorities is fed back to the base station through different second target PUCCH resources.
[0157] In the above embodiments, the second terminal can feed back HARQ-ACK information corresponding to SPS PDSCHs of different priorities to the base station through different second target PUCCH resources. This also improves the reliability of HARQ-ACK information feedback, thereby improving the reliability of the TDD communication system.
[0158] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 8 As shown, Figure 8 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a second terminal that does not support the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0159] In step 801, in response to determining the HARQ-ACK information corresponding to the SPS PDSCH with different priorities of delayed feedback, the fifth PUCCH resource belonging to the available resources is determined.
[0160] In this embodiment of the disclosure, the second terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine the feedback resources corresponding to SPS PDSCH of different priorities.
[0161] In step 802, the fifth PUCCH resource is used as the second target PUCCH resource for feeding back the HARQ-ACK information corresponding to the first priority SPS PDSCH among the different priorities.
[0162] The first priority is higher than the second priority among the different priorities.
[0163] In step 803, the HARQ-ACK information corresponding to the SPSPDSCH of different priorities is fed back to the base station through different second target PUCCH resources.
[0164] In the above embodiments, the HARQ-ACK information corresponding to the high-priority SPS PDSCH is prioritized for searching available resources, which ensures the reliability of the HARQ-ACK information feedback corresponding to the high-priority SPS PDSCH and thus improves the reliability of the TDD communication system.
[0165] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 9 As shown, Figure 9 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a second terminal that does not support the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0166] In step 901, in response to determining the HARQ-ACK information corresponding to SPS PDSCHs with different priorities for delayed feedback, different second target PUCCH resources for feeding back the HARQ-ACK information corresponding to SPS PDSCHs with different priorities are determined in descending order of the different priorities.
[0167] In this embodiment of the disclosure, the second terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCHs of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCHs of different priorities are unavailable. It can also determine the feedback resources corresponding to SPS PDSCHs of different priorities that are delayed in their feedback. In step 902, if the sixth PUCCH resource has already been determined as the second target PUCCH resource for feeding back HARQ-ACK information corresponding to the first priority SPS PDSCH, it is determined that the sixth PUCCH resource cannot be used as the second target PUCCH resource for feeding back HARQ-ACK information corresponding to the second priority SPS PDSCH.
[0168] In this embodiment of the disclosure, the first priority is higher than the second priority. Once a sixth PUCCH resource is determined for feeding back HARQ-ACK information corresponding to a high-priority SPS PDSCH, this sixth PUCCH resource cannot be reused or preempted by HARQ-ACK information corresponding to a low-priority SPS PDSCH.
[0169] In step 903, the HARQ-ACK information corresponding to the SPSPDSCH of different priorities is fed back to the base station through different second target PUCCH resources.
[0170] In the above embodiments, the reliability of HARQ-ACK information feedback corresponding to high-priority SPS PDSCH is ensured, thereby improving the reliability of the TDD communication system.
[0171] In some optional embodiments, a HARQ-ACK information feedback method is provided, referring to Figure 10 As shown, Figure 10 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a second terminal that does not support the reuse of HARQ-ACK information corresponding to SPS PDSCH. The method may include the following steps:
[0172] In step 1001, in response to determining the HARQ-ACK information corresponding to SPS PDSCHs with different priorities for delayed feedback, different second target PUCCH resources for feeding back the HARQ-ACK information corresponding to SPS PDSCHs with different priorities are determined in descending order of the different priorities.
[0173] In this embodiment of the disclosure, the second terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCHs of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCHs of different priorities are unavailable. It can also determine the feedback resources corresponding to the delayed feedback of SPS PDSCHs of different priorities. In step 1002, if the seventh PUCCH resource has already been determined as the second target PUCCH resource for feeding back HARQ-ACK information corresponding to the second priority SPS PDSCH, the seventh PUCCH resource is determined as the second target PUCCH resource for feeding back HARQ-ACK information corresponding to the first priority SPS PDSCH.
[0174] In this embodiment of the disclosure, if the seventh PUCCH resource has been determined as the second target PUCCH resource corresponding to the low-priority SPS PDSCH, the second terminal may also determine the seventh PUCCH resource as the second target PUCCH resource corresponding to the high-priority SPSPDSCH.
[0175] It should be noted that step 1002 is an optional implementation method. That is, if the seventh PUCCH resource has been determined as the second target PUCCH resource corresponding to the low-priority SPS PDSCH, the high-priority SPS PDSCH may not preempt the seventh PUCCH resource.
[0176] In step 1003, the HARQ-ACK information corresponding to the SPSPDSCH of different priorities is fed back to the base station through different second target PUCCH resources.
[0177] In the above embodiments, the high-priority SPS PDSCH can preempt the PUCCH resources already determined by the low-priority SPS PDSCH, ensuring the reliability of the HARQ-ACK information feedback corresponding to the high-priority SPS PDSCH, thereby improving the reliability of the TDD communication system.
[0178] The HARQ-ACK information feedback method provided in this disclosure will now be introduced from the perspective of the base station. On the base station side, the method will also be described separately for cases where the terminal supports the multiplexing of HARQ-ACK information corresponding to SPS PDSCH.
[0179] In the first scenario, the terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH.
[0180] This disclosure provides a HARQ-ACK information feedback method, referring to... Figure 11 As shown, Figure 11 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a base station. The method may include the following steps:
[0181] In step 1101, the target HARQ-ACK information fed back by the first terminal through the first target PUCCH resource is received.
[0182] The first terminal supports the multiplexing of HARQ-ACK information corresponding to the SPS Physical Downlink Shared Channel (PDSCH) in a semi-static scheduling manner. The target HARQ-ACK information is the HARQ-ACK information obtained by the first terminal after multiplexing the HARQ-ACK information corresponding to the SPS PDSCH of different priorities when the delay feedback of the HARQ-ACK information corresponding to the SPS PDSCH of different priorities is determined.
[0183] In the above embodiments, for a first terminal that supports the multiplexing of HARQ-ACK information corresponding to SPS PDSCH, the base station can directly receive the target HARQ-ACK information fed back by the first terminal through the first target PUCCH resource. This target HARQ-ACK information is obtained by the first terminal multiplexing the HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined to delay feeding back the HARQ-ACK information corresponding to SPS PDSCH of different priorities. This achieves the purpose of feeding back HARQ-ACK information corresponding to SPS PDSCH of different priorities.
[0184] In one possible implementation, the first target PUCCH resource may include, but is not limited to, any of the following resources: a first PUCCH resource belonging to available resources indicated by a first downlink control information (DCI); wherein the first DCI is used to activate an SPS PDSCH of the first priority among the different priorities pre-configured for the first terminal, the first priority being higher than the second priority among the different priorities; a second PUCCH resource belonging to available resources in a first PUCCH resource pool corresponding to the SPS PDSCH of the first priority; a third PUCCH resource belonging to available resources indicated by a second DCI; wherein the second DCI is used to activate an SPS PDSCH of the second priority among the different priorities pre-configured for the first terminal; or a fourth PUCCH resource belonging to available resources in a second PUCCH resource pool corresponding to the SPS PDSCH of the second priority.
[0185] In one possible implementation, the target HARQ-ACK information includes HARQ-ACK information corresponding to the second priority SPS PDSCH appended to the HARQ-ACK information corresponding to the first priority SPS PDSCH; wherein the first priority is higher than the second priority.
[0186] In the second scenario, the terminal does not support the reuse of HARQ-ACK information corresponding to SPS PDSCH.
[0187] This disclosure provides a HARQ-ACK information feedback method, referring to... Figure 12 As shown, Figure 12 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment, which can be applied to a base station. The method may include the following steps:
[0188] In step 1201, the second terminal receives HARQ-ACK information corresponding to the semi-static scheduling SPS physical downlink shared channel PDSCH of different priorities, fed back by the second terminal through different second target PUCCH resources in descending order of priority.
[0189] The second terminal does not support the reuse of HARQ-ACK information corresponding to SPS PDSCH.
[0190] In the above embodiments, for a second terminal that does not support the multiplexing of HARQ-ACK information corresponding to SPS PDSCH, the base station can receive HARQ-ACK information corresponding to the semi-statically scheduled SPS physical downlink shared channel PDSCH with different priorities fed back by the second terminal through different second target PUCCH resources in descending order of priority. This also achieves the purpose of feeding back HARQ-ACK information corresponding to SPS PDSCH with different priorities.
[0191] In some alternative embodiments, refer to Figure 13 As shown, Figure 13 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment. The method may include the following steps:
[0192] In step 1301, in response to determining the HARQ-ACK information corresponding to the SPS PDSCH with different priorities of delayed feedback, the first terminal appends the HARQ-ACK information corresponding to the SPS PDSCH with the second priority to the HARQ-ACK information corresponding to the SPS PDSCH with the first priority, and obtains the target HARQ-ACK information.
[0193] Wherein, the first priority is higher than the second priority. The first terminal supports the reuse of HARQ-ACK information corresponding to SPS PDSCH. The first terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCH of different priorities when it is determined that the initial HARQ-ACK feedback resources corresponding to SPS PDSCH of different priorities are unavailable, and can also determine to delay the feedback resources corresponding to SPS PDSCH of different priorities.
[0194] In step 1302, the first terminal determines a first target physical uplink control channel (PUCCH) resource for feeding back the target HARQ-ACK information.
[0195] The method for determining the primary target PUCCH resource can be referred to the above. Figure 3A , Figure 3B , Figure 4A , Figure 4B Any of the methods will not be elaborated here.
[0196] In one possible implementation, if the first terminal determines that the total number of bits occupied by the target HARQ-ACK information is greater than the maximum number of bits carried by the first target PUCCH resource, the corresponding HARQ-ACK information is discarded in ascending order of priority of SPS PDSCH until the total number of bits occupied by the target HARQ-ACK information is less than or equal to the maximum number of bits carried by the first target PUCCH resource.
[0197] In step 1303, the first terminal feeds back the target HARQ-ACK information to the base station through the first target PUCCH resource.
[0198] In the above embodiments, for the first terminal that supports the multiplexing of HARQ-ACK information corresponding to SPS PDSCH, a multiplexing method for HARQ-ACK information corresponding to SPS PDSCH with different priorities and a method for obtaining the feedback target HARQ-ACK information after multiplexing are provided, which improves the reliability of HARQ-ACK information feedback and thus improves the reliability of TDD communication system.
[0199] In some alternative embodiments, refer to Figure 14 As shown, Figure 14 This is a flowchart illustrating a HARQ-ACK information feedback method according to an embodiment. The method may include the following steps:
[0200] In step 1401, in response to determining the delay feedback of HARQ-ACK information corresponding to SPS PDSCH with different priorities, the second terminal determines different second target PUCCH resources for feeding back HARQ-ACK information corresponding to SPS PDSCH with different priorities in descending order of the different priorities.
[0201] The second terminal does not support the multiplexing of HARQ-ACK information corresponding to the semi-statically scheduled SPS physical downlink shared channel (PDSCH). The second terminal can determine to delay the feedback of HARQ-ACK information corresponding to SPS PDSCHs of different priorities when the initial HARQ-ACK feedback resources corresponding to SPS PDSCHs of different priorities are unavailable, and can also determine to delay the feedback resources corresponding to SPS PDSCHs of different priorities.
[0202] In step 1402, the second terminal feeds back the HARQ-ACK information corresponding to the SPS PDSCH of different priorities to the base station through different second target PUCCH resources.
[0203] In the above embodiments, for the second terminal that does not support the multiplexing of HARQ-ACK information corresponding to SPS PDSCH, a method is provided to feed back HARQ-ACK information corresponding to SPS PDSCH with different priorities, which also improves the reliability of HARQ-ACK information feedback, thereby improving the reliability of the TDD communication system.
[0204] It should also be noted that, in the embodiments disclosed herein, the methods for determining whether a PUCCH resource is an available PUCCH resource include, but are not limited to, the following:
[0205] Determine whether the PUCCH resource has been occupied by other terminals; determine whether the time slot corresponding to the PUCCH resource is an uplink time slot; determine whether the PUCCH resource is only available for certain types or several types of terminal services.
