Description

Feedback method, device, equipment and storage medium for semi-permanent scheduling

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a feedback method, a device, equipment and a storage medium for semi-permanent scheduling.

Background

An NR (New Radio) system supports multiple SPS (Semi-persistent scheduling) configurations. For each SPS configuration of data transmitted on the corresponding SPS PDSCH (Semi-Persistent Schedule Physical Downlink Shared Channel, physical downlink shared channel), the terminal device needs to feed back HARQ-ACKs (Hybrid Automatic Repeat request-Acknowledge character, hybrid automatic repeat request-acknowledgement character) to the network device.

However, although the network device configures a plurality of SPS configurations for the terminal device, the network device does not necessarily perform data transmission on all SPS PDSCHs to which all SPS configurations correspond. In the related art, in order to accommodate fluctuations in data arrival, a network device often configures a plurality of SPS configurations for a terminal device to accommodate data arriving at any time. In practice, only one SPS PDSCH corresponding to one SPS configuration among the SPS configurations will carry data in a transmission period of one downlink data. That is, in the transmission period of the downlink data, the terminal device only feeds back HARQ-ACK to the network device for the data transmitted on one SPS PDSCH, and the other SPS PDSCH does not actually carry data, so that the HARQ-ACK feedback corresponding to the SPS PDSCH has no meaning to the network device. One way to optimize HARQ-ACK feedback is to feed back HARQ-ACKs according to SPS groups (groups), i.e. multiple SPS configurations for the same service form one SPS group, where HARQ-ACK feedback is for the overall data reception situation of one SPS group, so that feedback of redundant invalid HARQ-ACKs by a terminal device to a network device can be avoided.

However, even if multiple SPS configurations belong to the same SPS group, HARQ-ACK feedback corresponding to the multiple SPS configurations may be mapped in different timeslots, so that the terminal device needs to feed back HARQ-ACKs to the network device for SPS PDSCH corresponding to each of the multiple SPS configurations in the same SPS group in different timeslots. Thus, the power consumption of the terminal equipment is not reduced, and the processing overhead of the terminal equipment is wasted.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

First, some terms involved in the embodiments of the present application will be described.

1. HARQ (Hybrid Automatic Repeat Request hybrid automatic repeat request)

HARQ is a technique formed by combining forward error correction coding (Forward Error Correction, FEC) and Automatic Repeat-reQuest (ARQ). The FEC technique is used at the receiving end to correct the portion of all errors that can be corrected. And judging that the data packet with the error cannot be corrected through error detection. Discarding the data packet which cannot correct the error, and requesting the same data packet to be retransmitted to the transmitting end.

2. SPS configuration

SPS configuration, also known as semi-persistent scheduling, allows semi-persistent configuration of radio resources and periodic allocation of the resources to a particular terminal device, as opposed to allocation of radio resources once per TTI (transmission time interval, scheduling period) as in dynamic scheduling (specified by PDCCH (Physical Uplink Control Channel, physical uplink control channel)).

For example, the network device designates an SPS PDSCH used by the terminal device using an SPS C-RNTI (Cell-radio network temporary identifier) scrambled PDCCH at a certain TTI, and the terminal device receives or transmits data using the SPS PDSCH every one period. The network device need not issue a PDCCH in this subframe (which will be referred to herein as an SPS subframe) to specify the allocated resources. Because the SPS configuration has the characteristic of "one configuration, multiple uses", DCI (Downlink Control Information ) (including uplink or downlink DCI) does not need to be issued for the terminal device in each TTI, thereby reducing the corresponding PDCCH overhead.

Referring to fig. 1, a schematic diagram of a system architecture according to an embodiment of the present application is shown. The system architecture may include: a terminal device 10 and a network device 20.

The number of terminal devices 10 is typically plural, and one or more terminal devices 10 may be distributed within a cell managed by each network device 20. The terminal device 10 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), mobile Station (MS), and the like, having wireless communication capabilities. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a terminal device.

The network device 20 is a means deployed in the access network to provide wireless communication functionality for the terminal device 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of network device-capable devices may vary in systems employing different radio access technologies, for example in 5G (5 th-Generation, fifth Generation mobile communication technology) NR systems, called gndeb or gNB. As communication technology evolves, the name "network device" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal device 10 with the wireless communication function are collectively referred to as a network device. Optionally, the network device 20 and the terminal device 10 communicate with each other via some air interface technology, such as Uu interface.

In one example, the network device 20 may configure a plurality of SPS configurations for the terminal device 10, and transmit data to the terminal device 10 through SPS PDSCH corresponding to the SPS configurations, and the terminal device 10 feeds back HARQ-ACK to the network device 20 based on the data reception situation.

The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand the meaning thereof.

It should be understood that the technical solution of the embodiments of the present application may be applied to various communication systems, for example: a long term evolution (Long Term Evolution, LTE) system, a LTE frequency division duplex (Frequency Division Duplex, FDD) system, a LTE time division duplex (Time Division Duplex, TDD) system, a long term evolution advanced (Advanced Long Term Evolution, LTE-a) system, a NR system, an evolution system of a NR system, a LTE-based access to Unlicensed spectrum, LTE-U, an NR-U, wireless local area network (Wireless Local Area Networks, WLAN), wireless fidelity (Wireless Fidelity, wiFi), a next generation communication system, or other communication system over an Unlicensed frequency band, and the like.

Generally, the number of connections supported by the conventional communication system is limited and easy to implement, however, as the communication technology advances, the mobile communication system will support not only the conventional communication but also other types of communication, such as Device-to-Device (D2D) communication, machine-to-machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), inter-vehicle (Vehicle to Vehicle, V2V) communication, and internet of vehicles (Vehicle to everything, V2X) systems. The embodiments of the present application may also be applied to these communication systems.

In one example, the NR system supports multiple SPS configurations. For each SPS configuration of data transmitted on the corresponding SPS PDSCH, the terminal device needs to feed back HARQ-ACKs to the network device.

However, although the network device configures a plurality of SPS configurations for the terminal device, the network device does not necessarily perform data transmission on all SPS PDSCHs to which all SPS configurations correspond. In the related art, in order to accommodate fluctuations in data arrival, a network device often configures a plurality of SPS configurations for a terminal device to accommodate data arriving at any time. In practice, only one SPS PDSCH corresponding to one SPS configuration among the SPS configurations will carry data in a transmission period of one downlink data. That is, in the transmission period of the downlink data, the terminal device only feeds back HARQ-ACK to the network device for the data transmitted on one SPS PDSCH, and the other SPS PDSCH does not actually carry data, so that the HARQ-ACK feedback corresponding to the SPS PDSCH has no meaning to the network device.

For example, as shown in fig. 2, for a service with a transmission period of 4 slots and a data arrival fluctuation range of 0-12 slots, the network device configures 7 SPS configurations for the terminal device: SPS configuration 1, SPS configuration 2, SPS configuration 3, SPS configuration 4, SPS configuration 5, SPS configuration 6, SPS configuration 7. The starting slots of SPS PDSCH corresponding to the 7 SPS configurations are respectively offset by {0,2,4,6,8, 10, 12} slots, and the period of each SPS configuration is 4 slots. Therefore, in practice, only one SPS PDSCH corresponding to one SPS configuration out of the 7 SPS configurations will carry data in the same period. For example, as shown in fig. 2 (1), the SPS PDSCH corresponding to SPS configuration 1 carries data, and the SPS PDSCH corresponding to the remaining 6 SPS configurations does not carry data, the terminal device feeds back HARQ-ACK to the network device: a, N (1,0,0,0,0,0,0); wherein, a represents ACK (acknowledgement) for indicating that the terminal device receives data in SPS PDSCH corresponding to SPS configuration 1; n represents NACK (negative acknowledgement) for indicating that the terminal device does not receive data in SPS PDSCH corresponding to SPS configuration 2 to SPS configuration 7, respectively. As another example, as shown in fig. 2 (2), if SPS PDSCH carrying data corresponding to SPS configuration 4 and SPS PDSCH carrying no data corresponding to the remaining 6 SPS configurations, the terminal device feeds back HARQ-ACK to the network device: n, N, N, A, N, N, N (0,0,0,1,0,0,0). Based on the example shown in fig. 2, it can be seen that only one SPS PDSCH is actually required for the terminal device to feed back HARQ-ACKs, and HARQ-ACKs corresponding to other SPS PDSCH are not significant to the network device.

In one example, the HARQ-ACK feedback is optimized by feeding back HARQ-ACKs according to an SPS group (in this embodiment, the SPS group is also referred to as an "HARQ-ACK packet"), that is, multiple SPS configurations for the same service form one HARQ-ACK packet, where the HARQ-ACK feedback is for the overall data receiving situation of one HARQ-ACK packet, so that feedback of redundant invalid HARQ-ACKs by the terminal device to the network device can be avoided.

For example, as shown in fig. 3, the network device divides 7 SPS configurations into the same HARQ-ACK packet, and the SPS configurations included in the HARQ-ACK packet correspond to the same HARQ-ACK feedback time unit 30. Therefore, the terminal device feeds back HARQ-ACK to the network device through the HARQ-ACK feedback time unit 30 for the data reception situation on the SPS PDSCH corresponding to the 7 SPS configurations. As shown in fig. 3 (1), the SPS PDSCH corresponding to SPS configuration 7 carries data, and if the terminal device correctly receives data on the SPS PDSCH corresponding to SPS configuration 7, the terminal device feeds back HARQ-ACK to the network device: and (5) ACK. As shown in fig. 3 (2), the SPS PDSCH corresponding to SPS configuration 4 carries data, and if the terminal device correctly receives data on the SPS PDSCH corresponding to SPS configuration 4, the terminal device feeds back HARQ-ACK to the network device: and (5) ACK.

However, even if multiple SPS configurations belong to the same SPS group, HARQ-ACK feedback corresponding to the multiple SPS configurations may be mapped in different feedback time units, so that the terminal device needs to feedback HARQ-ACKs to the network device for SPS PDSCH corresponding to each of the multiple SPS configurations in the same SPS group in different feedback time units.

For example, as shown in fig. 4, the network device divides 7 SPS configurations into the same HARQ-ACK packet, and the SPS configurations in the packet correspond to 4 HARQ-ACK feedback time units: a 1 st HARQ-ACK feedback time unit 410, a 2 nd HARQ-ACK feedback time unit 420, a 3 rd HARQ-ACK feedback time unit 430, and a 4 th HARQ-ACK feedback time unit 440. Wherein SPS configuration 1 and SPS configuration 2 correspond to the 1 st HARQ-ACK feedback time unit 410; SPS configuration 3 and SPS configuration 4 correspond to HARQ-ACK feedback time unit 2 420; SPS configuration 5 and SPS configuration 6 correspond to the 3 rd HARQ-ACK feedback time unit 430; SPS configuration 7 corresponds to HARQ-ACK feedback time unit 4 440. And the terminal equipment feeds back the data receiving conditions on the SPS PDSCH corresponding to the 7 SPS configurations to the network equipment through the 4 HARQ-ACK feedback time units respectively.

As shown in fig. 4 (1), the SPS PDSCH corresponding to SPS configuration 7 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 7. Since the terminal device does not correctly receive data in the SPS PDSCH corresponding to the first 6 SPS configurations respectively (the SPS PDSCH corresponding to the first 6 SPS configurations respectively does not carry data), the terminal device feeds back HARQ-ACKs to the network device in the 1 st HARQ-ACK feedback time unit 410, the 2 nd HARQ-ACK feedback time unit 420, and the 3 rd HARQ-ACK feedback time unit 430 respectively: NACK; and at the 4 th HARQ-ACK feedback time unit 440 feeds back HARQ-ACKs to the network device: and (5) ACK. As shown in fig. 4 (2), the SPS PDSCH corresponding to SPS configuration 4 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 4. Since the terminal device does not correctly receive data in the SPS PDSCH corresponding to the other 6 SPS configurations respectively (the SPS PDSCH corresponding to the other 6 SPS configurations respectively does not carry data), the terminal device feeds back HARQ-ACKs to the network device in the 1 st HARQ-ACK feedback time unit 410, the 3 rd HARQ-ACK feedback time unit 430, and the 4 th HARQ-ACK feedback time unit 440: NACK, and at 2 nd HARQ-ACK feedback time unit 420, feedback HARQ-ACK to the network device: and (5) ACK.

Based on the example shown in fig. 4, it can be seen that the terminal device may need to feed back HARQ-ACKs to the network device in different feedback time units for SPS PDSCH respectively corresponding to multiple SPS configurations in the same SPS group. Thus, the power consumption of the terminal equipment is not reduced, and the processing overhead of the terminal equipment is wasted. Based on this, the embodiment of the application provides a feedback method of semi-permanent scheduling, which can be used for reducing the processing overhead and the power consumption of the terminal equipment. The following describes the technical solution of the present application in connection with several embodiments.

Referring to fig. 5, a flow chart of a semi-persistent scheduling feedback method provided by an embodiment of the present application is shown. The method can be applied in a system architecture as shown in fig. 1. As shown in fig. 5, the method includes at least one or more of the following steps.

In step 510, the network device sends an SPS activation instruction to the terminal device, where the SPS activation instruction is used to activate a first SPS configuration, and the first SPS configuration corresponds to the first HARQ-ACK packet.

The network device sends one or more SPS activation instructions to the terminal device, and the terminal device activates corresponding SPS configuration according to each SPS activation instruction. For convenience of description, in the embodiment of the present application, the network device sends an SPS activation command to the terminal device is described as an example, but this is not a limitation of the present application.

Taking the example that the network device sends an SPS activation command to the terminal device, optionally, the SPS activation command is carried in DCI. In this embodiment of the present application, the SPS activation instruction is used to activate the first SPS configuration. The first SPS configuration may be one SPS configuration, but embodiments of the present application do not exclude the possibility that the first SPS configuration may be multiple SPS configurations.

Optionally, one SPS configuration corresponds to one HARQ-ACK packet, one HARQ-ACK packet including at least one SPS configuration. In this embodiment, the first SPS configuration corresponds to a first HARQ-ACK packet, where the first HARQ-ACK packet includes at least one SPS configuration, that is, the first HARQ-ACK packet may include other SPS configurations in addition to the first SPS configuration.

In one example, the first SPS configuration activated by the SPS activation instruction is a first SPS configuration of one or more SPS configurations that the network device previously configured for the terminal device. That is, as shown in fig. 6, before the step 510, the method further includes the step 500: the network device transmits SPS configuration information to the terminal device, the SPS configuration information being used to configure the first SPS configuration. For convenience of description, in the embodiment of the present application, the network device sends one SPS configuration information to the terminal device is described by taking the example that the network device sends one SPS configuration information to the terminal device as an example, and it should be understood that this is not a limitation of the present application. Taking the example that the network device sends an SPS configuration information to the terminal device, the SPS configuration information is used to configure the first SPS configuration, but the embodiment of the application does not exclude the possibility that the SPS configuration information also configures other SPS configurations at the same time. The embodiment of the application does not limit specific configuration parameters included in the SPS configuration information, and optionally, the SPS configuration information includes at least one of the following configuration parameters: SPS configuration index, HARQ-ACK packet corresponding to SPS configuration, SPS configuration period, SPS configuration repetition number, SPS configuration resource location.

Taking the example that the network device configures a plurality of SPS configurations for the terminal device in advance, alternatively, the plurality of SPS configurations may correspond to (or be referred to as "belong to") the same HARQ-ACK packet, or may correspond to a plurality of different HARQ-ACK packets. For example, the network device has previously configured 7 SPS configurations for the terminal device, the 7 SPS configurations corresponding to the same HARQ-ACK packet. For another example, the network device configures 7 SPS configurations for the terminal device in advance, SPS configuration 1, SPS configuration 2, SPS configuration 3 in the 7 SPS configurations correspond to one HARQ-ACK packet, SPS configuration 4, SPS configuration 5, SPS configuration 6, SPS configuration 7 correspond to another HARQ-ACK packet.

In step 520, the terminal device configures data transmitted on the corresponding SPS PDSCH for the SPS included in the first HARQ-ACK packet, and feeds back HARQ-ACKs to the network device based on the first HARQ-ACK feedback time unit.

In one example, the network device may send data to the terminal device on an SPS PDSCH corresponding to the first SPS configuration after activating the first SPS configuration by the SPS activation instruction. That is, as shown in fig. 6, after the step 510, step 530 is further included: and the network equipment transmits data to the terminal equipment on the SPS PDSCH corresponding to the first SPS configuration. Since the possibility that the network device activates other SPS configurations is not excluded in the embodiments of the present application, the network device may also send data to the terminal device on the SPS PDSCH corresponding to the other SPS configurations. In the case of a network device activating multiple SPS configurations, the network device may also send data to the terminal device on SPS PDSCH corresponding to a portion of the multiple SPS configurations, respectively, i.e., there may be no data actually carried on SPS PDSCH corresponding to a portion of the multiple SPS configurations that are activated. Optionally, in the same data transmission period, the network device transmits data to the terminal device only on the SPS PDSCH corresponding to one SPS configuration.

After the network device sends the data to the terminal device, the terminal device needs to feed back HARQ-ACK to the network device for the data reception situation. Optionally, the terminal device groups feed back HARQ-ACKs to the network device, so that feedback redundancy null HARQ-ACKs can be avoided. Based on this, in the embodiment of the present application, the terminal device feeds back the HARQ-ACK to the network device for the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK packet, that is, for the data receiving case corresponding to the first HARQ-ACK packet.

In one example, where the first HARQ-ACK packet includes multiple SPS configurations, the HARQ-ACK feedback time units corresponding to the multiple SPS configurations may be mapped in different time domain locations. In this embodiment of the present application, whether or not the HARQ-ACK feedback time unit corresponding to the SPS configuration included in the first HARQ-ACK packet is mapped to a different time domain position, the terminal device feeds back the HARQ-ACK to the network device based on the first HARQ-ACK feedback time unit. Optionally, the feedback of the terminal device to the network device based on the first HARQ-ACK feedback time unit is feedback for the overall data receiving situation of the first HARQ-ACK packet, but this does not constitute limitation of the embodiment of the present application, for example, the feedback of the terminal device to the network device based on the first HARQ-ACK feedback time unit may also be feedback for the data receiving situation corresponding to a certain SPS configuration in the first HARQ-ACK packet.

Optionally, in the embodiment of the present application, the first HARQ-ACK packet corresponds to 1 bit of feedback information bit, so that the terminal device may feed back ACK or NACK to the network device. For example, in the case that the terminal device feeds back 1 to the network device, that is, indicates that the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK packet is correctly received; in case the terminal device feeds back 0 to the network device, i.e. it indicates that the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK packet is not received correctly.

The embodiment of the present application does not limit the expression form of the first HARQ-ACK feedback time unit, and optionally, the first HARQ-ACK feedback time unit includes any one of the following time units: time slots, sub-time slots, symbols, frames, subframes. In this embodiment of the present application, a specific determination manner of the first HARQ-ACK feedback time unit is not limited, and optionally, the SPS activation instruction includes HARQ-ACK timing information corresponding to a first SPS configuration, where the HARQ-ACK timing information corresponding to the first SPS configuration is used to indicate the first HARQ-ACK feedback time unit. Based on this, the above method further comprises: the terminal equipment determines a first HARQ-ACK feedback time unit based on the HARQ-ACK timing information corresponding to the first SPS configuration and the data transmission time unit of the SPS PDSCH corresponding to the first SPS configuration. In an exemplary embodiment, the terminal device offsets the data transmission time unit of the SPS PDSCH corresponding to the first SPS configuration according to the HARQ-ACK timing information corresponding to the first SPS configuration, so as to obtain a first HARQ-ACK feedback time unit. For example, the HARQ-ACK timing information corresponding to the first SPS configuration is 4 slots, and the data transmission time unit of the SPS PDSCH corresponding to the first SPS configuration is slot 3, then the first HARQ-ACK feedback time unit is slot 7.

For other descriptions of the first HARQ-ACK feedback time unit and the first SPS configuration, please refer to the following method embodiments, which are not repeated here.

In summary, according to the technical solution provided in the embodiments of the present application, the terminal device feeds back HARQ-ACK to the network device based on one HARQ-ACK feedback time unit according to the data receiving situation of the SPS PDSCH corresponding to the SPS configuration included in one HARQ-ACK packet, so that the data receiving situation of the SPS PDSCH corresponding to the SPS configuration belonging to the same HARQ-ACK packet is achieved in one HARQ-ACK feedback time unit to the network device, the situation that the terminal device needs to feed back HARQ-ACK to the network device according to the same HARQ-ACK packet in different HARQ-ACK feedback time units is avoided, which is conducive to reducing power consumption and processing overhead of the terminal device, and meanwhile, reliability and efficiency of uplink transmission are also improved.

In the embodiment of the application, in order to realize that the terminal equipment feeds back the HARQ-ACK to the network equipment in one HARQ-ACK feedback time unit aiming at the same HARQ-ACK packet, a plurality of ways for determining the first HARQ-ACK feedback time unit are provided. These various modes will be described below.

First, a first mode will be described: the corresponding HARQ-ACK feedback time units of SPS configuration belonging to the same HARQ-ACK packet are aligned.

In one example, the SPS configuration corresponding HARQ-ACK timing information included in the first HARQ-ACK packet is used to indicate the first HARQ-ACK feedback time unit.

That is, the first HARQ-ACK packet includes the HARQ-ACK timing information corresponding to each SPS configuration, so that the HARQ-ACK feedback time units corresponding to each SPS configuration are ensured to be the same HARQ-ACK feedback time unit, that is, the first HARQ-ACK feedback time unit, so as to achieve alignment of the HARQ-ACK feedback time units corresponding to each SPS configuration belonging to the same HARQ-ACK packet.

For example, as shown in fig. 7, the network device divides 7 SPS configurations into the same HARQ-ACK packet, where the HARQ-ACK feedback time unit corresponding to each SPS configuration is the HARQ-ACK feedback time unit 710. As shown in fig. 7, the starting slots of SPS PDSCH corresponding to these 7 SPS configurations are offset by {0,1,2,3,4,5,6} slots, respectively, and the period of each SPS configuration is 10 slots. To ensure that the 7 SPS configurations correspond to the same HARQ-ACK feedback time unit 710, the HARQ-ACK timing information for the 7 SPS configurations needs to be configured as {7,6,5,4,3,2,1} slots, respectively.

Next, a second way is described: and taking SPS configuration corresponding to SPS PDSCH of correctly received data in one HARQ-ACK packet as a basis for determining the HARQ-ACK feedback time unit corresponding to the HARQ-ACK packet.

In one example, the first SPS configuration refers to an SPS configuration corresponding to an SPS PDSCH in which the terminal device correctly receives data, among SPS configurations included in the first HARQ-ACK packet.

That is, the terminal device uses the SPS configuration corresponding to the SPS PDSCH, which correctly receives data, in the SPS configuration included in one HARQ-ACK packet, as the HARQ-ACK feedback time unit for the data reception situation of the HARQ-ACK packet. Since in this example the terminal device correctly receives data on the SPS PDSCH corresponding to the first SPS configuration, the HARQ-ACK includes an ACK; the step 520 includes: the terminal equipment feeds back the ACK to the network equipment based on the first HARQ-ACK feedback time unit aiming at the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK packet. For the SPS configuration corresponding to the SPS PDSCH which does not correctly receive data in the SPS configuration included in the first HARQ-ACK packet, the terminal device does not feed back the HARQ-ACK to the network device.

For example, as shown in fig. 8, the network device divides 7 SPS configurations into the same HARQ-ACK packet, and the SPS configurations in the packet correspond to 4 HARQ-ACK feedback time units: a 1 st HARQ-ACK feedback time unit 810, a 2 nd HARQ-ACK feedback time unit 820, a 3 rd HARQ-ACK feedback time unit 830, and a 4 th HARQ-ACK feedback time unit 840. Wherein SPS configuration 1 and SPS configuration 2 correspond to the 1 st HARQ-ACK feedback time unit 810; SPS configuration 3 and SPS configuration 4 correspond to HARQ-ACK feedback time unit 2 820; SPS configuration 5 and SPS configuration 6 correspond to the 3 rd HARQ-ACK feedback time unit 830; SPS configuration 7 corresponds to the 4 th HARQ-ACK feedback time unit 840.

As shown in fig. 8, the starting slots of SPS PDSCH corresponding to the 7 SPS configurations are respectively offset by {0,1,2,3,4,5,6} slots, HARQ-ACK timing information corresponding to the 7 SPS configurations is respectively configured as {2,1,2,1,2,1,1} slots, and the period of each SPS configuration is 10 slots. As shown in fig. 8 (1), for the first data transmission period, the SPS PDSCH corresponding to SPS configuration 7 carries data, and if the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 7, the terminal device feeds back HARQ-ACKs to the network device in the 4 th HARQ-ACK feedback time unit 840 (slot 7) corresponding to SPS configuration 7. As shown in fig. 8 (2), for the 2 nd data transmission period, the SPS PDSCH corresponding to SPS configuration 4 carries data, and the terminal device correctly receives the data in the SPS PDSCH corresponding to SPS configuration 4, the terminal device feeds back the HARQ-ACK to the network device in the 2 nd HARQ-ACK feedback time unit 820 (slot 14) corresponding to SPS configuration 4.

Next, a third mode is described: SPS configuration meeting a certain condition in one HARQ-ACK packet is used as the basis for determining the HARQ-ACK feedback time unit corresponding to the HARQ-ACK packet.

In one example, the first SPS configuration refers to an SPS configuration satisfying the first condition among SPS configurations included in the first HARQ-ACK packet.

That is, the terminal device uses the HARQ-ACK feedback time unit corresponding to the SPS configuration satisfying the first condition in the SPS configuration included in one HARQ-ACK packet as the HARQ-ACK feedback time unit for the data reception situation of the HARQ-ACK packet. The embodiment of the present application does not limit the specific content of the first condition, and optionally, the first condition includes any one of the following: the SPS PDSCH data transmission unit in the SPS configuration included in the first HARQ-ACK packet is located at a last SPS configuration index in the SPS configuration included in the first HARQ-ACK packet that is the smallest, the SPS configuration index in the SPS configuration included in the first HARQ-ACK packet that is the largest, and the SPS configuration included in the first HARQ-ACK packet that is configured to determine the first HARQ-ACK feedback time unit.

In this example, the HARQ-ACK needs to be fed back to the network device, whether or not the terminal device is correctly receiving data. Based on this, optionally, the HARQ-ACK includes an ACK or NACK; the step 520 includes: the terminal equipment feeds back ACK to the network equipment based on a first HARQ-ACK feedback time unit under the condition that the terminal equipment correctly receives data on an SPS PDSCH corresponding to SPS configuration included in the first HARQ-ACK packet; and the terminal equipment feeds back NACK to the network equipment based on the first HARQ-ACK feedback time unit under the condition that the terminal equipment does not correctly receive data on the SPS PDSCH corresponding to SPS configuration included in the first HARQ-ACK packet. That is, only if the terminal device does not correctly receive data on SPS PDSCH corresponding to all SPS configurations included in the first HARQ-ACK packet, the terminal device feeds back NACK to the network device, and otherwise, the terminal device feeds back ACK to the network device. It should be understood that this is not limiting to the present application, for example, the terminal device may also feed back to the network device a reception situation of data transmitted on the SPS PDSCH corresponding to a specific SPS configuration in the first HARQ-ACK packet, and if the data transmitted on the SPS PDSCH corresponding to the SPS configuration is correctly received, the terminal device feeds back an ACK to the network device; and if the data transmitted on the SPS PDSCH corresponding to the SPS configuration is not received correctly, the terminal equipment feeds back NACK to the network equipment.

For example, as shown in fig. 9, the network device divides 7 SPS configurations into the same HARQ-ACK packet, and the SPS configurations in the packet correspond to 4 HARQ-ACK feedback time units: a 1 st HARQ-ACK feedback time unit 910, a 2 nd HARQ-ACK feedback time unit 920, a 3 rd HARQ-ACK feedback time unit 930, and a 4 th HARQ-ACK feedback time unit 940. Wherein SPS configuration 1 and SPS configuration 2 correspond to the 1 st HARQ-ACK feedback time unit 910; SPS configuration 3 and SPS configuration 4 correspond to HARQ-ACK feedback time unit 2 920; SPS configuration 5 and SPS configuration 6 correspond to the 3 rd HARQ-ACK feedback time unit 930; SPS configuration 7 corresponds to the 4 th HARQ-ACK feedback time unit 940.

As shown in fig. 9, the starting slots of SPS PDSCH corresponding to the 7 SPS configurations are respectively offset by {0,1,2,3,4,5,6} slots, HARQ-ACK timing information corresponding to the 7 SPS configurations is respectively configured as {2,1,2,1,2,1,1} slots, and the period of each SPS configuration is 10 slots. As shown in fig. 9 (1), for the first data transmission period, the SPS PDSCH corresponding to SPS configuration 7 carries data, and the terminal device correctly receives the data in the SPS PDSCH corresponding to SPS configuration 7, since the data transmission unit of the SPS PDSCH corresponding to SPS configuration 7 is located at the last, the terminal device feeds back HARQ-ACK to the network device at the 4 th HARQ-ACK feedback time unit 940 (slot 7) corresponding to SPS configuration 7. As shown in fig. 9 (2), for the 2 nd data transmission period, the SPS PDSCH corresponding to SPS configuration 4 carries data, and the terminal device correctly receives the data in the SPS PDSCH corresponding to SPS configuration 4, and still because the data transmission unit of the SPS PDSCH corresponding to SPS configuration 7 is located at the last, the terminal device feeds back the HARQ-ACK to the network device at the 4 th HARQ-ACK feedback time unit 940 (slot 17) corresponding to SPS configuration 7.
