Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a semi-static scheduling HARQ feedback processing method, apparatus, terminal, and base station. Background Technology

[0002] In non-terrestrial network (NTN) communication, the Hybrid Automatic Repeat reQuest (HARQ) process can be configured to either enable or disable HARQ process feedback. Radio Resource Control (RRC) independently configures the enable or disable status of each HARQ process feedback. For semi-persistent scheduling (SPS), in existing technologies, each associated HARQ process feedback is enabled independently via RRC. This makes the unified configuration of HARQ process feedback to enable or disable in SPS transmissions quite complex. Summary of the Invention

[0003] The purpose of this invention is to provide a semi-static scheduling HARQ feedback processing method, apparatus, terminal, and base station, which solves the problem that the operation of uniformly configuring HARQ process feedback to an enabled and disabled state in SPS transmission is relatively complex.

[0013] The configuration module is used to configure the feedback status of the Hybrid Automatic Repeat Request (HARQ) process associated with the target semi-static scheduling (SPS) physical downlink shared channel (PDSCH) transmission, based on the target parameters.

[0014] The target parameters include:

[0015] The first parameter is a HARQ process feedback configuration indication associated with each SPS PDSCH.

[0031] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0032] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0033] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0034] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0035] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0036] It should be noted that in certain special scenarios, configuring a unified enabled or disabled state for HARQ process feedback in SPS transmissions can improve communication efficiency or quality. For example, in VoIP services, due to the high latency characteristics of NTN, if all HARQ process feedbacks for SPS transmissions are configured to be enabled, all HARQ processes allocated to SPS may be occupied. Furthermore, since the Transport Blocks (TBs) received by the UE need to be output sequentially, when the HARQ process feedback corresponding to one TB is NACK, subsequent TBs need to wait for the retransmission of that TB, which can lead to problems such as excessively long waiting times, excessive TB accumulation causing excessive pressure on the UE's buffer, and impacting the UE's throughput. Therefore, in VoIP services, there is a need to configure all HARQ process feedbacks for SPS transmissions to be disabled. While the need to uniformly configure each HARQ process associated with semi-static scheduling to be enabled or disabled is reasonable, existing technologies require configuring the feedback state of each related HARQ process individually through RRC, which presents operational complexity.

[0037] Specifically, embodiments of the present invention provide a semi-static scheduling HARQ feedback processing method, which solves the problem that the operation of uniformly configuring HARQ process feedback to an enabled state and a disabled state in SPS transmission is relatively complicated in the prior art.

[0038] like Figure 1As shown, a semi-static scheduling HARQ feedback processing method according to an embodiment of the present invention is applied to a terminal and includes the following steps:

[0039] Step 101: Receive Radio Resource Control (RRC) configuration signaling sent by the base station; the RRC configuration signaling includes target parameters;

[0040] The target parameters include: a first parameter, which is a HARQ process feedback configuration indication associated with each SPS PDSCH.

[0041] In this step, the first parameter is used to indicate the feedback status configuration of the HARQ processes associated with the target SPS PDSCH. Specifically, the first parameter is a newly added HARQ process feedback configuration indication parameter (harq-FeedbackIndicateforSPS) in the RRC configuration. The terminal can use this first parameter to uniformly configure the feedback status for multiple HARQ processes associated with the target SPS PDSCH; the feedback status includes whether HARQ process feedback is enabled or disabled. For example, if there are N SPS PDSCH transmissions after SPS activation, this first parameter is used to indicate the feedback status configuration of the HARQ processes associated with those N SPS PDSCH transmissions. That is, the first parameter indicates whether the feedback status of all HARQ processes associated with the N SPS PDSCH transmissions is either HARQ process feedback enabled or all HARQ process feedback is disabled.

[0042] Step 102: Configure the feedback state of the hybrid automatic repeat request associated with the target semi-static scheduling SPS physical downlink shared channel (PDSCH) transmission according to the target parameters.

[0043] In this step, when there are a total of N SPS PDSCH transmissions associated with RRC configuration signaling after SPS activation, the target SPS PDSCH transmission is at least a portion of the N SPS PDSCH transmissions.

[0044] In this embodiment, the terminal can conveniently configure the feedback status for the HARQ process associated with the target SPS PDSCH transmission in a unified manner according to the first parameter, which solves the problem of complex operation in the existing method of configuring the feedback status for each HARQ process individually in SPS transmission.

[0045] It should be noted that the target parameter in an RRC configuration signaling is only used to indicate the feedback status configuration of the HARQ process in the SPS PDSCH transport associated with that RRC configuration signaling. Other SPS PDSCH transports are configured by the target parameters in the RRC configuration signaling associated with them.

[0046] Optionally, the first parameter can also be included in the downlink dedicated configuration signaling, in which case the parameter can control the enabling or disabling of HARQ process feedback in all SPS transmissions associated with this downlink dedicated configuration signaling.

[0047] In one embodiment, the target parameter further includes a second parameter, which indicates the feedback status of the HARQ process associated with the first PDSCH transmission after SPS activation.

[0048] Specifically, the second parameter is the SPS-activated HARQ feedback enable parameter (harq-FeedbackEnablingforSPSactive), which is only used to configure the enable state of HARQ process feedback associated with the first PDSCH transmission.

[0049] In one embodiment, when the target parameter includes only the first parameter, the target SPSPDSCH transmission is N PDSCH transmissions associated with the RRC configuration signaling; configuring the feedback status of the Hybrid Automatic Repeat Request (HARQ) process associated with the target SPS Physical Downlink Shared Channel (PDSCH) transmission according to the target parameter includes:

[0050] Based on the first parameter, the HARQ process feedback associated with the N PDSCH transmissions is uniformly configured to either a first feedback state or a second feedback state. The first feedback state is HARQ process feedback enabled, and the second feedback state is HARQ process feedback disabled; N is a positive integer.

[0051] For example, when the first parameter is configured to 0, the HARQ process feedback associated with the N PDSCH transmissions is uniformly configured to a first feedback state; when the first parameter is configured to 1, the HARQ process feedback associated with the N PDSCH transmissions is uniformly configured to a second feedback state.

[0052] In this embodiment, when the target parameters include only the first parameter and not the second parameter, the feedback status of the HARQ process associated with the N PDSCH transmissions of the RRC configuration signaling is uniformly configured according to the first parameter. In this way, the feedback status of the HARQ process associated with the N PDSCH transmissions of the RRC configuration signaling can be conveniently configured to disable or enable HARQ process feedback.

[0053] In one embodiment, when the target parameter includes the first parameter and the second parameter, the second parameter has a higher priority than the first parameter.

[0054] In this embodiment, when the target parameters include both the first parameter and the second parameter, the feedback state of the HARQ process associated with the first PDSCH transmission after SPS activation is configured primarily based on the second parameter. That is, although the first parameter indicates the feedback state of the HARQ process for N PDSCH transmissions associated with RRC configuration signaling, the feedback state of the HARQ process associated with the first PDSCH transmission is configured solely based on the second parameter.

[0055] In one embodiment, when the target parameters include the first parameter and the second parameter, the target SPS PDSCH transmission is the 2nd to Nth PDSCH transmission associated with the RRC configuration signaling; configuring the feedback status of the Hybrid Automatic Repeat Request (HARQ) process associated with the target SPS Physical Downlink Shared Channel (PDSCH) transmission according to the target parameters includes:

[0056] Based on the second parameter, the HARQ process feedback associated with the first PDSCH transmission after SPS activation is configured to a first feedback state, where the first feedback state is HARQ process feedback enabled.

[0057] Based on the first parameter, the HARQ process feedback associated with the 2nd to Nth PDSCH transmissions is uniformly configured to either the first feedback state or the second feedback state; the second feedback state is HARQ process feedback disabled; N is a positive integer.

[0058] For example, when the target parameters also include a second parameter, if the first parameter is configured to 1, the HARQ process feedback corresponding to the first SPS PDSCH after SPS activation is configured to be enabled, and the HARQ process feedback corresponding to the second to Nth SPS PDSCHs is configured to be disabled.

[0059] For example, when the target parameters do not include the second parameter, the HARQ process feedback status associated with the N SPS PDSCH transmissions is configured according to the first parameter. For instance, when the first parameter is 0, the HARQ process feedback associated with the N PDSCH transmissions is uniformly configured to be enabled; when the first parameter is 1, the HARQ process feedback associated with the N PDSCH transmissions is uniformly configured to be disabled.

[0060] In this embodiment, when the target parameters include the first parameter and the second parameter, regardless of whether the HARQ process feedback associated with the N PDSCH transmissions indicated by the first parameter is enabled, the HARQ process feedback associated with the first PDSCH transmission after SPS activation is configured to be enabled, and the terminal provides feedback on the ACK / NACK of the first SPS PDSCH after activation.

[0061] It should be noted that in the prior art, the target parameters do not include the first parameter and the second parameter. The feedback status of the HARQ process associated with SPSPDSCH needs to be configured individually for each HARQ process according to the configuration in the RRC signaling. The embodiments of this application can achieve unified configuration of the feedback status for each HARQ process associated with SPS through the first parameter and the second parameter, thereby facilitating unified configuration of the feedback status of HARQ processes in SPS transmission.

[0062] like Figure 2 As shown, a semi-static scheduling HARQ feedback processing method according to an embodiment of the present invention is applied to a base station, including:

[0063] Step 201: Send RRC configuration signaling to the terminal; the configuration signaling includes target parameters;

[0064] The target parameters include: a first parameter, which is a HARQ process feedback configuration indication associated with each SPS PDSCH.

[0065] In this step, the first parameter is used to indicate the feedback status configuration of the HARQ processes associated with the target SPS PDSCH. Specifically, the first parameter is a newly added HARQ process feedback configuration indication parameter (harq-FeedbackIndicateforSPS) in the RRC configuration. The terminal can use this first parameter to uniformly configure the feedback status for multiple HARQ processes associated with the target SPS PDSCH; the feedback status includes HARQ process feedback enabled or HARQ process disabled. For example, if there are N SPS PDSCH transmissions after SPS activation, the first parameter is used to indicate the feedback status configuration of the HARQ processes associated with the N SPS PDSCH transmissions. That is, the first parameter indicates that the feedback status of all HARQ processes associated with the N SPS PDSCH transmissions is either HARQ process feedback enabled or all HARQ process feedback is disabled. In this way, the terminal can conveniently configure the feedback status for the HARQ process associated with the target SPS PDSCH transmission in a unified manner based on the first parameter, which solves the problem of complex operation in configuring the feedback status for each HARQ process individually in SPS transmission.

[0066] In one embodiment, the target parameter further includes a second parameter, which indicates the feedback status of the HARQ process associated with the first PDSCH transmission after SPS activation.

[0067] Specifically, the second parameter is the SPS-activated HARQ feedback enable parameter (harq-FeedbackEnablingforSPSactive), which is only used to configure the feedback enable state of the HARQ process associated with the first PDSCH transmission.

[0068] In one embodiment, when the target parameter includes the first parameter and the second parameter, the second parameter has a higher priority than the first parameter.

[0069] In this embodiment, when the target parameters include both the first parameter and the second parameter, the feedback state of the HARQ process associated with the first PDSCH transmission after SPS activation is configured primarily based on the second parameter. That is, although the first parameter indicates the feedback state of the HARQ process for N PDSCH transmissions associated with RRC configuration signaling, the feedback state of the HARQ process associated with the first PDSCH transmission is configured solely based on the second parameter.

[0073] The target parameters include: a first parameter, which is a HARQ process feedback configuration indication associated with each SPS PDSCH.

[0074] Optionally, the target parameter further includes a second parameter, which indicates the feedback status of the HARQ process associated with the first PDSCH transmission after SPS activation.

[0075] Optionally, if the target parameter includes only the first parameter, the target SPS PDSCH transmission is N PDSCH transmissions associated with the RRC configuration signaling; the configuration module 302 is specifically used for:

[0076] Based on the first parameter, the HARQ process feedback associated with the N PDSCH transmissions is uniformly configured to either a first feedback state or a second feedback state. The first feedback state is HARQ process feedback enabled, and the second feedback state is HARQ process feedback disabled; N is a positive integer.

[0077] Optionally, when the target parameter includes the first parameter and the second parameter, the second parameter has a higher priority than the first parameter.

[0078] Optionally, when the target parameter includes the first parameter and the second parameter, the target SPS PDSCH transmission is the 2nd to Nth PDSCH transmission associated with the RRC configuration signaling; the configuration module 302 is specifically used for:

[0080] Based on the first parameter, the HARQ process feedback associated with the second to Nth PDSCH transmissions is uniformly configured to either the first feedback state or the second feedback state; the second feedback state is HARQ process feedback disabled.

The bus architecture can also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface.

For different user equipment, user interface 530 can also be an interface capable of connecting external or internal devices, including but not limited to keypads, displays, speakers, microphones, joysticks, etc.

[0095] The processor 500 is responsible for managing the bus architecture and general processing, while the memory 520 can store the data used by the processor 500 when performing operations.

[0096] Optionally, the target parameter further includes a second parameter, which indicates the feedback status of the HARQ process associated with the first PDSCH transmission after SPS activation.

[0097] Optionally, if the target parameter includes only the first parameter, the target SPS PDSCH transmission is N PDSCH transmissions associated with the RRC configuration signaling; when the processor 500 executes the program or instruction, it implements the following steps:

[0107] The transceiver 610 is used to receive and send data under the control of the processor 600.

[0108] Among them, Figure 6 In this context, the bus architecture may include any number of interconnected buses and bridges, specifically linking various circuits together, represented by one or more processors (processor 600) and memory (memory 620). The bus architecture may also link together various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface.

For example, an identified executable code module may include one or more physical or logical blocks of computer instructions, which may be constructed as objects, procedures, or functions. Nevertheless, the executable code of the identified module does not need to be physically located together, but may include different instructions stored in different bits, which, when logically combined, constitute the module and achieve the module's intended purpose.

[0115] In practice, an executable code module can be a single instruction or many instructions, and can even be distributed across multiple different code segments, different programs, and across multiple memory devices. Similarly, operational data can be identified within the module and can be implemented in any suitable form and organized within any suitable type of data structure. This operational data can be collected as a single dataset or distributed across different locations (including different storage devices), and can exist, at least in part, solely as electronic signals within the system or network.

[0116] When a module can be implemented using software, considering the current level of hardware technology, modules that can be implemented in software can be implemented using hardware circuits by those skilled in the art to achieve the corresponding functions, without considering cost. These hardware circuits include conventional very-large-scale integrated circuits (VLSI) or gate arrays, as well as existing semiconductors such as logic chips and transistors, or other discrete components. Modules can also be implemented using programmable hardware devices, such as field-programmable gate arrays, programmable array logic, and programmable logic devices.
