Description

[0001] This application is a divisional application, the parent application is No. 202180081203.6, the application date is March 16, 2021, and the invention name is "information transmission method, device, equipment and storage medium". TECHNICAL FIELD

[0002] The present application relates to the field of mobile communication, in particular to an information transmission method, device, equipment and storage medium. BACKGROUND

[0003] In a wireless communication system, a terminal device and a network device can use SPS (Semi Persistent Schedule) data. The network device configures SPS transmission parameters for the terminal device. The terminal device determines the transmission resource configured by the network device according to the SPS transmission parameters configured by the network device. The network device sends SPS PDSCH (Physical Downlink Shared Channel) on the transmission resource. The terminal device sends corresponding feedback information to the network device according to the received SPS PDSCH.

[0004] However, in order to prevent the system efficiency from being reduced due to the feedback information corresponding to the SPS PDSCH being discarded, the terminal device is allowed to delay sending the feedback information. However, delaying the sending of the feedback information will cause the timing relationship of the PDSCH to be chaotic, and thus the transmission accuracy of the feedback information corresponding to the SPS PDSCH will be reduced.

[0060] For the purpose, technical solutions and advantages of the present application to be more clear, the present application embodiments will be further described in detail below with reference to the drawings.

[0061] First, the terms involved in the present application are explained:

[0062] SPS PDSCH:

[0063] In the NR system, there are two data transmission modes: dynamic transmission mode and semi-persistent / semi-static transmission mode. The dynamic transmission is characterized in that the parameters of each data transmission are indicated by the corresponding DCI (Downlink Control Information).

[0064] Among them, the DCI includes the information of the resources used by the PDSCH, HARQ process number, etc.

[0065] In addition, the characteristics of semi-persistent / semi-static transmission are that the transmission resources and transmission modes are semi-persistently / semi-statically configured, and DCI is used to activate / release the corresponding SPS transmission. If the corresponding SPS is activated, subsequent transmissions no longer need to send physical layer signaling.

[0066] The network device pre-configures SPS transmission parameters for the terminal device through high-layer signaling.

[0067] In some embodiments, the SPS transmission parameters include at least one of the following:

[0068] (1) SPS cycle.

[0069] (2) Time domain resources.

[0070] (3) PUCCH resources used to transmit feedback information.

[0071] In some embodiments, the PUCCH format configured by the network device for transmitting feedback information for the SPS PDSCH includes PUCCH format 0 or PUCCH format 1. The maximum number of bits of feedback information carried by PUCCH format 0 or PUCCH format 2 is 2.

[0072] After the network device configures the SPS transmission parameters for the terminal device, it activates the SPS through DCI, and the SPS transmission parameters are further indicated in the DCI.

[0073] In some embodiments, the SPS transmission parameters include at least one of the following:

[0074] (1) Frequency domain resources.

[0075] (2) Feedback duration.

[0076] For example, Figure 1 As shown, after the network device sends DCI signaling to activate SRS, in the absence of dynamic scheduling within the same time domain resources, the network device will always send an SPS PDSCH, and the terminal device will also send feedback information corresponding to the SPS PDSCH through PUCCH.

[0077] In some embodiments, if the time domain resources determined according to the preconfigured feedback time slot cannot be used to transmit the PUCCH, for example, the time domain symbols occupied by the PUCCH are downlink symbols, the feedback information of the SPS PDSCH will not be transmitted.

[0078] PDSCH timing relationship:

[0079] The first one:

[0080] If the terminal device receives the first PDSCH, the HARQ process number corresponding to the first PDSCH is X, and before the terminal device transmits the feedback information corresponding to the first PDSCH, the terminal device does not expect the base station to schedule a second PDSCH carrying a HARQ process with a number X of the first PDSCH. That is, as shown in FIG. 1, after transmitting a HARQ process X through PDSCH 1, and before transmitting the feedback information corresponding to the HARQ process X, the base station cannot repeatedly use the same number for data transmission. Figure 2

[0081] Secondly, as shown in FIG. 2, the terminal device receives PDSCH 1 in time slot I, and the feedback information corresponding to PDSCH 1 is transmitted through time slot J. The terminal device does not expect to receive a PDSCH 2 whose starting symbol is after the starting symbol of PDSCH 1, and whose feedback information is before the feedback information of PDSCH 1.

[0082] Figure 3

[0083] Next, the application scenario of the present application is described as follows:

[0084] Figure 4 A block diagram of a communication system provided by an exemplary embodiment of the present application is shown, which can include an access network 12 and a terminal device 13.

[0085] The access network 12 includes a plurality of network devices 120. The network device 120 can be a base station, which is a device deployed in an access network to provide wireless communication functions for terminal devices. The base station can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions can be different, for example, in an LTE system, it is called eNodeB or eNB; in a 5G NR-U system, it is called gNodeB or gNB. As communication technology evolves, the description of "base station" can change. For convenience in the embodiments of the present application, the above-mentioned devices providing wireless communication functions for terminal devices are collectively referred to as access network devices.

[0086] ​​​The terminal device 13 can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication functions, and various forms of user equipment, mobile stations (MS), terminal devices, and the like. For convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The access network device 120 and the terminal device 13 communicate with each other through a certain air interface technology, such as a Uu interface.

[0087] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an Advanced long term evolution (LTE-A) system, a New Radio (NR) system, an evolved system of the NR system, an LTE-based access to unlicensed spectrum (LTE-U) system, an NR-U system, a Universal Mobile Telecommunication System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a Wireless Local Area Networks (WLAN), a Wireless Fidelity (WiFi), a next-generation communication system, or other communication systems.

[0088] Generally, a conventional communication system supports a limited number of connections and is easy to implement. However, with the development of communication technology, a mobile communication system will not only support conventional communication, but also support, for example, Device to Device (D2D) communication, Machine to Machine (M2M) communication, Machine Type Communication (MTC), Vehicle to Vehicle (V2V) communication, and Vehicle to everything (V2X) system, etc. The embodiments of the present application can also be applied to these communication systems.

[0089] Figure 5 A flowchart of an information transmission method provided by an example embodiment of the present application is shown, which is applied to a terminal device and a network device as shown in Figure 4 The method includes at least part of the following contents:

[0090] 510, The terminal device determines at least one feedback information associated with the first time domain unit.

[0091] In the embodiments of the present application, the network device pre-configures SPS PDSCH transmission parameters for the terminal device to perform data transmission, and the terminal device receives the SPS PDSCH transmitted by the network device according to the configured SPS PDSCH transmission parameters.

[0092] The first time domain unit is one of a plurality of pre-configured time domain units obtained by the terminal device. The at least one feedback information includes non-delayed feedback information and delayed feedback information.

[0093] In some embodiments, the feedback information includes ACK (Acknowledgement) information or NACK (Negative Acknowledgement) information. The ACK information is used to indicate that the terminal device confirms to receive the SPS PDSCH. The NACK information is used to indicate that the terminal device confirms not to receive the SPS PDSCH.

[0094] The non-delayed feedback information includes feedback information corresponding to the first SPS PDSCH, and the first time domain unit is a time domain unit for transmitting the feedback information corresponding to the first SPS PDSCH, which is determined according to the feedback time length. The delayed feedback information includes feedback information that is unsuccessfully transmitted in a second time domain unit, and the feedback information that is unsuccessfully transmitted in the second time domain unit is feedback information corresponding to the second SPS PDSCH, and the second time domain unit is a time domain unit for transmitting the feedback information corresponding to the second SPS PDSCH, which is determined according to the feedback time length.

[0095] The feedback duration is a duration for the terminal device to receive the SPS PDSCH and transmit the feedback information corresponding to the SPS PDSCH. For example, if the feedback duration is 1 slot, the terminal device receives the SPS PDSCH in the first slot and transmits the feedback information corresponding to the SPS PDSCH in the second slot. If the feedback duration is 2 slots, the terminal device receives the SPS PDSCH in the first slot and transmits the feedback information corresponding to the SPS PDSCH in the third slot.

[0096] In addition, the at least one feedback information associated with the first time domain unit includes feedback information of unsuccessful transmission in the second time domain unit, which indicates that the second time domain unit is located before the first time domain unit.

[0097] In some embodiments, the first time domain unit is a slot, or the first time domain unit is a sub-slot, or the first time domain unit is at least one time domain symbol, and the embodiments of the present application do not limit the first time domain unit.

[0098] In some embodiments, the terminal device determines at least one second time domain unit located before the first time domain unit and separated from the first time domain unit by a multiple of the feedback duration, and determines the feedback information of unsuccessful transmission in the at least one second time domain unit as the feedback information associated with the first time domain unit.

[0099] For example, taking the first time domain unit as a slot as an example. If the first time domain unit is slot 4 and the feedback duration is 1 slot, the time domain units before the first time domain unit are slot 1, slot 2 and slot 3, the slot 1 is separated from the slot 4 by a multiple of 2 of the feedback duration, the slot 2 is separated from the slot 4 by a multiple of 1 of the feedback duration, and the slot 3 is separated from the slot 4 by a multiple of 0 of the feedback duration. The feedback information of unsuccessful transmission in the slot 1, the slot 2 and the slot 3 is determined as the feedback information associated with the first time domain unit.

[0100] In other embodiments, the terminal device determines that the time domain unit for transmitting the second SPS PDSCH is located before the first time domain unit and separated from the first time domain unit by a time domain length not greater than the maximum delay length.

[0101] In the embodiments of the present application, the maximum delay length is provided to control the duration of the feedback information corresponding to the SPS PDSCH that can be delayed. For example, if the maximum delay length is 3 slots and the feedback duration is 1 slot, the terminal device receives the SPS PDSCH in the first slot, and the feedback information corresponding to the SPS PDSCH is transmitted at the latest in the fifth slot. If it exceeds the fifth slot, the feedback information will not be transmitted again.

[0102] For example, taking a time slot as the first time domain unit for example. If the first time domain unit is time slot 4, and the feedback duration is 1 time slot, the time domain units before the first time domain unit are time slot 1, time slot 2, and time slot 3 respectively. The time slot 1 is separated from the time slot 4 by 2 times the feedback duration, the time slot 2 is separated from the time slot 4 by 1 times the feedback duration, and the time slot 3 is separated from the time slot 4 by 0 times the feedback duration. The feedback information that is not successfully transmitted on the time slot 1, the time slot 2, and the time slot 3 is determined as the feedback information associated with the first time domain unit.

[0103] 520、The terminal device determines at least one PUCCH resource according to the at least one feedback information.

[0104] In the embodiment of the present application, the terminal device determines at least one feedback information associated with the first time domain unit, and then determines at least one PUCCH resource that meets the requirement according to the bit number of the at least one feedback information.

[0105] The network device pre-configures a PUCCH resource for the terminal device to transmit information. For example, the terminal device obtains two PUCCH resources in a time slot, and the two PUCCH resources are a first PUCCH resource and a second PUCCH resource respectively. The first PUCCH resource and the second PUCCH resource are both configured by the network device.

[0106] In some embodiments, the PUCCH resources pre-configured by the network device for the terminal device carry different bit numbers. For example, if the network device configures two PUCCH resources for the terminal device, which are a first PUCCH resource and a second PUCCH resource respectively, the first PUCCH resource carries at most 2 bits of feedback information, and the second PUCCH resource carries more than 2 bits of feedback information. Alternatively, the PUCCH resource can also carry information of other bit numbers, and the embodiments of the present application do not limit the PUCCH resources configured by the network device for the terminal device.

[0107] In some embodiments, the terminal device determines at least one PUCCH resource according to the total bit number of the deferred feedback information and the non-deferred feedback information included in the at least one feedback information.

[0108] In the embodiment of the present application, the terminal device determines the PUCCH resource according to the size of the total bit number of the deferred feedback information and the non-deferred feedback information and the maximum bit number that the PUCCH resource can carry.

[0109] For example, if the total bit number of the deferred feedback information and the non-deferred feedback information is 6 bits, and the maximum bit number that the PUCCH resource can carry is 8 bits, it indicates that the bit number that the PUCCH resource can carry is greater than the total bit number of the deferred feedback information and the non-deferred feedback information, and the PUCCH resource can carry these feedback information.

[0110] For another example, if the total number of bits of the deferred feedback information and the non-deferred feedback information is 6 bits, and the maximum number of bits that the PUCCH resource can carry is 2 bits, it indicates that the number of bits that the PUCCH resource can carry is less than the total number of bits of the deferred feedback information and the non-deferred feedback information, and the PUCCH resource cannot carry the feedback information.

[0111] In some embodiments, the terminal device determines the at least one PUCCH resource according to the number of bits of the non-deferred feedback information included in the at least one feedback information.

[0112] In the embodiments of the present application, the terminal device determines the PUCCH resource according to the size of the number of bits of the non-deferred feedback information and the number of bits that the PUCCH resource can carry.

[0113] For example, if the number of bits of the non-deferred feedback information is 1 bit, and the maximum number of bits that the PUCCH resource can carry is 2 bits, it indicates that the number of bits that the PUCCH resource can carry is greater than the total number of bits of the non-deferred feedback information, and the PUCCH resource can carry the non-deferred feedback information.

[0114] For another example, if the number of bits of the non-deferred feedback information is 4 bits, and the maximum number of bits that the PUCCH resource can carry is 2 bits, it indicates that the number of bits that the PUCCH resource can carry is less than the total number of bits of the non-deferred feedback information, and the PUCCH resource cannot carry the non-deferred feedback information.

[0115] 530、The terminal device determines the feedback information to be sent in the first time domain unit according to the at least one PUCCH resource.

[0116] In the embodiments of the present application, after the terminal device determines the PUCCH resource that can carry the feedback information, the terminal device further needs to determine the feedback information to be transmitted in the first time domain unit according to whether the PUCCH resource is available.

[0117] In some embodiments, if the terminal device determines the first PUCCH resource according to the total number of bits of the deferred feedback information and the non-deferred feedback information included in the at least one feedback information, and the first PUCCH resource is available, the terminal device determines that the feedback information to be sent in the first time domain unit includes the deferred feedback information and the non-deferred feedback information.

[0118] In other embodiments, the terminal device determines the first PUCCH resource according to the total number of bits of the deferred feedback information and the non-deferred feedback information included in the at least one feedback information, determines the second PUCCH resource according to the number of bits of the non-deferred feedback information, and the first PUCCH resource is not available, and the second PUCCH resource is available, the terminal device determines that the feedback information to be sent in the first time domain unit includes the non-deferred feedback information.

[0119] If the terminal device determines that the feedback information sent in the first time domain unit includes non-deferred feedback information, the terminal device clears the deferred feedback information in the at least one feedback information.

[0120] In some embodiments, the terminal device clearing the postponed feedback information in the at least one feedback information may also be replaced by any of the following:

[0121] (1) The terminal device discards the deferred feedback information in at least one feedback information.

[0122] (2) The terminal device cancels the postponed feedback information in at least one feedback information.

[0123] (3) The terminal device skips the postponed feedback information in at least one feedback information.

[0124] (4) The terminal device does not store the deferred feedback information in the at least one feedback information.

[0125] For example, Figure 6 As shown, the time domain unit is a time slot as an example. The feedback information of SPS PDSCH 0 and SPSPDSCH 1 in time slot n is transmitted in time slot n+1, but this time slot is a downlink time slot and feedback information cannot be transmitted, so the corresponding feedback information needs to be postponed. The feedback information of SPS PDSCH 2 and SPS PDSCH 3 in time slot n+1 is transmitted in time slot n+2, but this time slot is a downlink time slot and feedback information cannot be transmitted, so the corresponding feedback information needs to be postponed. The feedback information of SPS PDSCH 4 and SPS PDSCH 5 in time slot n+2 is transmitted in time slot n+3. If only the 2-bit feedback information corresponding to SPSPDSCH 4 and SPS PDSCH 5 is transmitted in time slot n+3, PUCCH resource 1 is used, and the time domain symbols occupied by PUCCH resource 1 are all uplink symbols, that is, PUCCH resource 1 is available. However, in order to transmit the 6-bit feedback information corresponding to SPS PDSCH 0 to 5 in time slot n+3, PUCCH resource 2 is required, but the time domain symbols occupied by PUCCH resource 2 include downlink symbols, that is, PUCCH resource 2 is not available. Therefore, the terminal device determines that the 2-bit feedback information corresponding to SPS PDSCH 4 and SPS PDSCH 5 is transmitted in time slot n+3, and clears the feedback information of SPS PDSCH 0 to 3.

[0126] It should be noted that the embodiment of the present application is only described by taking whether the PUCCH resource is available as an example. In another embodiment, how to determine whether the PUCCH resource is unavailable will be described.

[0127] In some embodiments, PUCCH resources being unavailable includes:

[0128] The time domain symbol occupied by the PUCCH resource includes at least one of the following cases:

[0129] (1) A downlink time domain symbol.

[0130] (2) A flexible time domain symbol.

[0131] (3) A time domain symbol occupied by a broadcast channel.

[0132] (4) A time domain symbol occupied by a synchronization channel.

[0133] (5) A time domain symbol occupied by a downlink reference symbol.

[0134] (6) A time domain symbol occupied by a control channel.

[0135] (7) A time domain symbol preconfigured by a network device.

[0136] If the time domain symbol in the PUCCH resource includes at least one of the following time domain symbols, it means that the time domain symbol in the PUCCH resource cannot be used for uplink transmission, and the PUCCH resource is unavailable.

[0137] In some other embodiments, the available PUCCH resource and the unavailable PUCCH resource are opposite conditions. If the terminal device determines that the PUCCH resource does not meet the unavailable condition, it is determined that the PUCCH resource is available.

[0138] In some other embodiments, the terminal device can also determine whether the PUCCH resource is available according to whether the PUCCH resource includes the following time domain symbols:

[0139] (1) The time domain symbol occupied by the PUCCH resource is an uplink symbol.

[0140] (2) The time domain symbol occupied by the PUCCH resource does not include a downlink symbol, a time domain symbol occupied by a broadcast channel, or a time domain symbol occupied by a synchronization channel.

[0141] If the terminal device determines that the time domain symbol occupied by the PUCCH resource is any one of the above two cases, it means that the PUCCH resource is an available resource.

[0142] It should be noted that the present embodiment only takes the determination of the feedback information sent in the first time domain unit from at least one feedback information as an example for description. In another embodiment, the at least one feedback information associated with the time domain unit obtained by the terminal device includes feedback information corresponding to multiple SPS PDSCHs, and the HARQ processes carried by the multiple SPS PDSCHs are different.

[0143] The terminal device controls the HARQ processes of the multiple SPS PDSCH bearers in different ways. Please refer to the following Figure 7 The method shown in the figure.

[0144] The embodiment of the present application provides an information transmission method. According to feedback information associated with a first time domain unit, a PUCCH resource meeting a requirement is determined. According to the PUCCH resource, feedback information capable of being transmitted in the first time domain unit is determined from at least one feedback information. It is ensured that the transmitted feedback information meets the transmission requirement, and the remaining feedback information does not need to be transmitted. It is ensured that the delayed feedback information does not affect the timing relationship of the PDSCH. The sending accuracy of the feedback information is improved. The transmission stability of the feedback information is also improved.

[0145] Figure 5 The embodiment describes how the terminal device determines the feedback information according to at least one feedback information and a PUCCH resource. In another embodiment, if the terminal device determines that the target information is empty, the terminal device further determines the feedback information according to a third time domain unit located after the first time domain unit. Please refer to Figure 7 Embodiment:

[0146] 710. If the terminal device determines that the feedback information transmitted in the first time domain unit is empty, at least one feedback information associated with the third time domain unit is determined.

[0147] In the embodiment of the present application, the feedback information transmitted in the first time domain unit determined by the terminal device through the above steps 510-530 is empty. It is indicated that the first time domain unit at this time still cannot transmit the feedback information. The terminal device needs to obtain at least one feedback information associated with a third time domain unit after the first time domain unit according to the third time domain unit.

[0148] In some embodiments, if the terminal device determines the first PUCCH resource according to the total number of bits of the delayed feedback information and the non-delayed feedback information included in the at least one feedback information, and the first PUCCH resource is unavailable, the terminal device determines that the feedback information transmitted in the first time domain unit is empty.

[0149] In another embodiment, the terminal device determines the first PUCCH resource according to the total number of bits of the delayed feedback information and the non-delayed feedback information included in the at least one feedback information, determines the second PUCCH resource according to the number of bits of the non-delayed feedback information, and the first PUCCH resource is unavailable. The second PUCCH resource is unavailable. The terminal device determines that the feedback information transmitted in the first time domain unit is empty.

[0150] The terminal device determines at least one feedback information associated with the third time domain unit. The process is similar to step 510, and will not be described here.

[0151] 720、The terminal device determines at least one PUCCH resource according to the at least one feedback information.

[0152] 730、The terminal device determines the feedback information transmitted in the first time domain unit according to the at least one PUCCH resource.

[0153] The steps 720-730 are similar to the steps 520-530, and will not be described here.

[0154] It should be noted that the embodiments of the present application are only described by taking the case of determining the feedback information according to the third time domain unit when the feedback information is empty as an example. In other embodiments, when the feedback information transmitted in the first time domain unit is empty, it is first determined whether the third time domain unit located after the first time domain unit includes a PUCCH resource. If the third time domain unit does not include a PUCCH resource, a fourth time domain unit located after the third time domain unit is obtained, and it is continued to determine whether the fourth time domain unit includes a PUCCH resource. Until the time domain unit including the PUCCH resource is determined, the step 710 is executed.

[0155] For example, in combination with Figure 6 The steps of the embodiments of the present application are described. If the terminal device determines that the first time domain unit is the slot n, the slot n is a downlink slot and does not include a PUCCH resource, and the slot n is skipped. The terminal device determines the feedback information associated with the slot n+1, and the slot n+1 is a downlink slot and does not include a PUCCH resource, and the slot n+1 is skipped. The terminal device determines the feedback information associated with the slot n+2, and the slot n+2 is a downlink slot and does not include a PUCCH resource, and the slot n+2 is skipped. The terminal device determines that the feedback information associated with the slot n+3 includes the feedback information corresponding to the SPS PDSCH 0-5, and the number of bits is 6, and the terminal device determines the PUCCH resource 2, and the part of the symbols occupied by the PUCCH resource 2 are downlink symbols, which indicates that the PUCCH resource is not available because the terminal device determines that the feedback information transmitted in the slot n+3 is empty. The terminal device determines the feedback information associated with the slot n+4, and the slot n+4 is a downlink slot and does not include a PUCCH resource, and the terminal device determines that the feedback information transmitted in the slot n+4 is empty, and the slot n+4 is skipped. The terminal device determines that the feedback information associated with the slot n+5 includes the feedback information corresponding to the SPS PDSCH 4-8, and the number of bits is 5, and determines the PUCCH resource 2, and the symbols occupied by the PUCCH resource 2 are all uplink symbols, and therefore the terminal device determines that the PUCCH resource 2 is available, and the feedback information of the SPS PDSCH 4-8 is transmitted in the slot n+5.

[0156] The method provided in the embodiments of the present application can improve the execution efficiency of the terminal device.

[0157] It should be noted that the above examples are only explained from the perspective of time domain units. In another embodiment, the examples can also be explained from the perspective of SPS PDSCH.

[0158] For example, taking the maximum feedback delay length of 2 slots as an example, in combination with Figure 6 For example, taking the maximum feedback delay length of 2 slots as an example, in combination with For example, taking the maximum feedback delay length of 2 slots as an example, in combination with

[0186] It should be noted that the embodiments of the present application Figure 8 may be combined with the above Figure 5 or Figure 7 embodiments, which are not limited by the present application.

[0187] The embodiments of the present application provide an information transmission method. The PUCCH resource meeting the requirement is determined according to the feedback information associated with the first time domain unit, and the feedback information that can be transmitted in the first time domain unit is determined according to the PUCCH resource from at least one feedback information, so as to ensure that the transmitted feedback information meets the transmission requirement, and the remaining feedback information does not need to be transmitted, so as to ensure that the delayed feedback information does not affect the timing relationship of the PDSCH, improve the sending accuracy of the feedback information, and improve the transmission stability of the feedback information.

[0188] Figure 9 A flowchart of an information transmission method provided by an example embodiment of the present application is shown, which is applied to a terminal device as shown in Figure 4 The method includes at least part of the following contents:

[0189] 910, the terminal device receives a first SPS PDSCH through a first time domain unit.

[0190] The first SPS PDSCH carries a first HARQ process, and the feedback information corresponding to the first SPS PDSCH is transmitted through a second time domain unit. The second time domain unit is a time domain unit after the feedback information corresponding to the first SPS PDSCH is delayed to be transmitted, or a time domain unit in which the feedback information corresponding to the first SPS PDSCH is not delayed to be transmitted.

[0191] In the embodiments of the present application, the network device sends a first SPS PDSCH to the terminal device through a first time domain unit, and the terminal device receives the first SPS PDSCH through the first time domain unit.

[0192] 920, if a third time domain unit is included in the time domain unit before the second time domain unit, and the second SPS PDSCH carries the first HARQ process, the feedback information corresponding to the first SPS PDSCH or the second SPS PDSCH is invalidated.

[0193] The third time domain unit is used to transmit the second SPS PDSCH.

[0194] In an embodiment of the present application, if the terminal device receives a first SPS PDSCH in a first time domain unit, and the time domain unit for sending the feedback information corresponding to the first SPS PDSCH is a second time domain unit, then before the second time domain unit, if there is a second SPS PDSCH with the same HARQ process as the first SPS PDSCH carried by the first SPS PDSCH, then in order to prevent timing confusion problems, the terminal device performs invalidation processing on the feedback information corresponding to the first SPS PDSCH or the second SPS PDSCH.

[0195] In some embodiments, the feedback information corresponding to the first SPS PDSCH by the terminal device includes: clearing the feedback information corresponding to the first SPS PDSCH.

[0196] The terminal device clearing the feedback information corresponding to the first SPS PDSCH may also be replaced by any of the following:

[0197] (1) The terminal device discards the feedback information corresponding to the first SPS PDSCH.

[0198] (2) The terminal device cancels the feedback information corresponding to the first SPS PDSCH.

[0199] (3) The terminal device skips the feedback information corresponding to the first SPS PDSCH.

[0200] (4) The terminal device does not store the feedback information corresponding to the first SPS PDSCH.

[0201] For example, Figure 10 As shown, two SPS PDSCHs are configured in each time slot of time slots n-n+3. The two SPS PDSCHs in time slot n carry HARQ process 0 and HARQ process 7 respectively, the two SPS PDSCHs in time slot n+1 carry HARQ process 1 and HARQ process 8 respectively, the two SPS PDSCHs in time slot n+2 carry HARQ process 2 and HARQ process 0 respectively, and the two SPS PDSCHs in time slot n+3 carry HARQ process 3 and HARQ process 1 respectively. If the first SPS PDSCH received by the terminal device in time slot n carries HARQ process 0, and the first SPS PDSCH is transmitted in time slot n+4, and the second SPS PDSCH in time slot n+2 carries HARQ process 0, then the terminal device needs to perform invalidation processing on the feedback information corresponding to the first SPS PDSCH or the second SPS PDSCH.

[0202] In some embodiments, the terminal device performs the invalidation processing on the second SPS PDSCH includes that the terminal device does not receive the second SPS PDSCH on the third time domain unit.

[0203] In some embodiments, if the terminal device receives a dynamically scheduled PDSCH before the second time domain unit, and the dynamically scheduled PDSCH carries a second HARQ process, the terminal device transmits corresponding feedback information according to the received dynamically scheduled PDSCH transmission, without performing step 920.

[0204] The method provided by the embodiments of the present application can prevent the problem of PDSCH time sequence disorder caused by carrying the same HARQ process, improve the sending accuracy of the feedback information, and improve the transmission stability of the feedback information.

[0205] Figure 9 The embodiments illustrate the process of how the terminal device performs the invalidation processing on the feedback information corresponding to the SPS PDSCH or the second SPS PDSCH, and the network device also determines how the terminal device performs the invalidation processing on the feedback information corresponding to the SPS PDSCH or the second SPS PDSCH, and then judges how to perform the subsequent process. The following Figure 11 The method provided by the embodiments of the present application can prevent the problem of PDSCH time sequence disorder caused by carrying the same HARQ process, improve the sending accuracy of the feedback information, and improve the transmission stability of the feedback information. Figure 11 The method includes:

[0206] 1110、The network device transmits a first SPS PDSCH through a first time domain unit.

[0207] The first SPS PDSCH carries a first HARQ process, and the feedback information corresponding to the first SPS PDSCH is transmitted through a second time domain unit.

[0208] The process of step 1110 is similar to the above-mentioned step 910, and will not be described here again.

[0209] 1120、If a time domain unit before the second time domain unit includes a third time domain unit, and the third time domain unit is used for transmitting the second SPS PDSCH, the network device determines feedback information corresponding to the first SPS PDSCH or the second SPS PDSCH to be invalid.

[0210] The second SPS PDSCH carries a first HARQ process.

[0211] In the embodiments of the present application, if the network device transmits the first SPS PDSCH in the first time domain unit, and the time domain unit in which the feedback information corresponding to the first SPS PDSCH is received is the second time domain unit, before the second time domain unit, if there is a second SPS PDSCH with the same HARQ process as the first SPS PDSCH, in order to prevent timing confusion, the terminal device invalidates the feedback information corresponding to the first SPS PDSCH or the second SPS PDSCH, and the network device needs to determine the feedback information or the SPS PDSCH invalidated by the terminal device.

[0212] In some other embodiments, the network device determining the second SPS PDSCH to be invalid includes that the network device does not transmit the second SPS PDSCH on the third time domain unit.

[0213] It should be noted that after the terminal device invalidates the feedback information corresponding to the first SPS PDSCH, the terminal device transmits other feedback information in the second time domain unit except the invalidated feedback information, and the network device receives the feedback information transmitted by the terminal device in the second time domain unit.

[0214] In some other embodiments, if the network device transmits a dynamically scheduled PDSCH before the second time domain unit, and the dynamically scheduled PDSCH carries a second HARQ process, the network device receives the corresponding feedback information according to the received dynamically scheduled PDSCH, and does not need to perform step 1120.

[0215] The method provided by the embodiment of the present application can determine the second time domain unit for transmitting the feedback information according to the SPS PDSCH transmitted in the first time domain unit, and if there is a third time domain unit before the second time domain unit and carrying the same HARQ process as the SPS PDSCH, and the feedback information corresponding to the SPS PDSCH received in the first time domain unit is not transmitted completely, the second SPS PDSCH carrying the same HARQ process cannot be received, it is determined that the feedback information corresponding to the first SPS PDSCH or the second SPS PDSCH is invalid, the problem of PDSCH time sequence disorder caused by carrying the same HARQ process is prevented, the transmission accuracy of the feedback information is improved, and the transmission stability of the feedback information is also improved.
