Detailed Description

The technical scheme of the present application will be specifically described below by examples and with reference to the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. It should be noted that: in the examples of the present application, "first," "second," etc. are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. In addition, the embodiments of the present application may be arbitrarily combined without any collision. The plurality of embodiments of the present application may refer to at least two, etc., respectively.

In a New Radio (NR) system, data transmission modes may include dynamic transmission and semi-persistent/semi-static transmission. The dynamic transmission is characterized in that the parameters of each data transmission are indicated by corresponding downlink control signaling (Downlink Control Information, DCI), and the DCI can include physical resources used by the PDSCH and/or information such as a hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process number. Semi-persistent/semi-persistent transmission is characterized in that both transmission resources and transmission modes are semi-persistent/semi-persistent configured, and DCI is used to activate/release a corresponding SPS transmission. Once activated, subsequent transmissions do not require physical layer signaling (e.g., DCI) scheduling.

In some embodiments, the terminal device may be configured with a set of SPS transmission parameters at most, with a period of at least 10ms. The network device configuring SPS transmit part parameters via higher layer signaling includes at least one of: periodic, time domain resources, physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources that transmit acknowledgement or non-acknowledgement (ACKnowledge/Negative ACKnowledge, ACK/NACK), and the like. Since the SPS transmission period is 10ms at the minimum, and the supported uplink-downlink switching period is 10ms at the maximum, that is, at least one certain uplink transmission resource is included in the 10ms period. The SPS PDSCH may thus employ independent feedback, i.e., one SPS PDSCH carries its ACK/NACK information for each PUCCH. The PUCCH configured by the network device for transmitting ACK/NACK to the SPS PDSCH may be PUCCH format 0 or PUCCH format 1, where the PUCCH format 0 or PUCCH format 1 may carry 2 bits of ACK/NACK information at most. Then, the network device may perform SPS activation or deactivation through downlink control signaling DCI, and further indicate SPS transmission part parameters in the activation signaling, which may include: frequency domain resources and/or feedback slots, etc. The feedback slot may be referred to as a time domain offset, denoted by k1, and k1 may represent a slot interval between a slot in which the SPS PDSCH is located and a slot in which the ACK/NACK transmission of the SPS PDSCH is located. Once SPS transmissions are activated, the network device always transmits an SPS PDSCH without dynamic scheduling within the same time resources, and the terminal device also always transmits ACK/NACK information corresponding to the SPS PDSCH. In the embodiment of the present application, any feedback information may be ACK/NACK information or HARQ-ACK codebook.

Fig. 1 is a schematic diagram of a relationship between an SPS PDSCH and a PUCCH in an SPS period, as shown in fig. 1, in a time t dimension, ACK/NACK information for the SPS PDSCH may be transmitted on the PUCCH after an interval time domain offset k1 in each SPS period.

To better support ultra-reliable low delay communications, the SPS period may be shortened to a minimum of 1ms. For an SPS PDSCH, if the time domain resource determined according to the preconfigured feedback slot (k 1) cannot be used to transmit the PUCCH, for example, the time domain symbol occupied by the PUCCH is a downlink symbol, the ACK/NACK information of the SPS PDSCH will not be transmitted.

In order to avoid system efficiency reduction caused by discarding ACK/NACK corresponding to SPS PDSCH, feedback enhancement of SPS PDSCH can be supported. For example, SPS ACK/NACK deferred transmission (release HARQ-ACK) may be supported. I.e. SPS PDSCH received in slot/sub-slot n, if PUCCH following slot/sub-slot n+k1 cannot transmit the corresponding ACK/NACK, where k1 may be preconfigured by the network device (e.g. indicated in the DCI by higher layer signaling configuration or activation signaling), the ACK/NACK information is deferred to slot/sub-slot n+k1+k _defer Is transmitted.

In order to reduce the complexity of the implementation of the terminal device, the following PDSCH timing relationship is still defined for data processing in one carrier:

Fig. 2 is a schematic diagram of a relation between PDSCH and feedback a/N provided by an embodiment of the present application, as shown in fig. 2, in a time dimension t, a terminal device receives a PDSCH 1, where the HARQ process number corresponding to the PDSCH 1 is X. Before the terminal device does not send the ACK/NACK (a/N) feedback information corresponding to the PDSCH 1, the terminal device does not expect the network device to schedule a new PDSCH 2, whose HARQ process number is the same as that of the PDSCH 1. That is, after a certain DownLink (DL) HARQ process is transmitted, but before the corresponding ACK/NACK feedback information is not transmitted, the network device cannot reuse the HARQ process number of the PDSCH 1 for data transmission.

Fig. 3 is a schematic diagram of another relation between PDSCH and feedback a/N provided by the embodiment of the present application, as shown in fig. 3, in the dimension of time t, a terminal device receives PDSCH 1 in time slot i, and its corresponding ACK/NACK information is transmitted through time slot j. The terminal device does not expect to receive PDSCH 2 with its starting symbol after the PDSCH 1 starting symbol, but the corresponding ACK/NACK (a/N) information is transmitted through the slot preceding slot j. I.e. scheduling the following PDSCH whose feedback cannot be preceded.

However, after the SPS ACK/NACK information deferral method is introduced, PDSCH timing may be broken.

Fig. 4 is a schematic diagram of feedback of SPS HARQ-ACK according to an embodiment of the present application, as shown in fig. 4, a terminal device may configure two sets of SPS configurations, that is, SPS configuration 1 and SPS configuration 2, where the preconfigured feedback slot k1 is 1 slot. In addition, the network device configures two PUCCH resources for transmitting SPS ACK/NACK, wherein PUCCH 1 (or PUCCH resource 1) is used for transmitting 1 or 2 bits of information, and PUCCH 2 (or PUCCH resource 2) is used for transmitting more than 2 bits of information. Uplink resources are configured in slot+3 and slot+5.

According to k1=1, feedback information of SPS PDSCH 0 and SPS PDSCH 1 in Slot (Slot) n is transmitted in Slot n+1, but the Slot is a downlink Slot, and feedback information cannot be transmitted, and the corresponding feedback information needs to be deferred. Feedback information of the SPS PDSCH 2 and the SPS PDSCH 3 in the Slot n+1 is transmitted in the Slot n+2, but the Slot is a downlink time Slot, and the feedback information cannot be transmitted, so that the corresponding feedback information needs to be deferred. Feedback information of the SPS PDSCH 4 and the SPS PDSCH 5 in Slot n+2 is transmitted in Slot n+3. If only 2-bit feedback information corresponding to SPS PDSCH 4 and SPS PDSCH 5 is transmitted in Slot n+3, PUCCH resource 1 may be used. And the time domain resource occupied by the PUCCH resource 1 is an uplink resource and can be transmitted. But the feedback information of SPS PDSCH 0-3 will be deferred until transmission in Slot n + 5. Out-of-order (out-of-order) occurs at this time, i.e., the corresponding timing constraint of fig. 3 is broken.

In order to at least solve the above problems, embodiments of the present application provide a data transmission method, apparatus, device, storage medium, chip, and product.

The network device in the implementation of the present application may be a network side device that performs Wireless communication with a terminal device, for example, an access point of Wireless Fidelity (Wi-Fi), an evolved base station, a base station of next generation communication, such as a gNB or a small station of 5G, a micro station or a transmission receiving point (transmission reception point, TRP), and may also be a relay station, an access point, a vehicle device, or a wearable device.

In the following, the data processing method provided by the embodiment of the present application is described, and in the implementation process, an execution body of the following method may include: a processor or chip, which may be applied in a terminal device or a network device. Alternatively, the execution subject may be a terminal device or a network device.

Fig. 5 is a schematic implementation flow chart of a data transmission method according to an embodiment of the present application, where, as shown in fig. 5, the method is applied to a terminal device, and the method includes:

s501, acquiring a feedback information set associated with a first time domain resource; the feedback information set includes: feedback information of the PDSCH of the M semi-persistent scheduling SPS physical downlink shared channels; m is an integer greater than or equal to 1.

Any time domain resource mentioned in the embodiments of the present application (for example, a first time domain resource or a second time domain resource, a third time domain resource, any one of one or more time domain resources, etc. described below) may include a frame, a subframe, a slot, a sub-slot, or Q time domain symbols; q is an integer greater than or equal to 1. The Q time domain symbols are time domain symbols that may be within one slot. In implementations, the Q time domain symbols may be any one of 1 to 13 number of time domain symbols. For example, the Q time domain symbols may be 1 time domain symbol, 2 time domain symbols, 4 time domain symbols, 8 time domain symbols, and so on.

The feedback information of the M SPS PDSCH may include: feedback information of one or more configured SPS PDSCH; at least one of a period, time domain resources, and frequency domain resources of the SPS PDSCH of different configurations is different. M may be 1 or M may be an integer greater than or equal to 2.

In some embodiments, the SPS PDSCH of different configurations corresponds to different services, for example, under a communication service or a network service, the SPS PDSCH may have a longer period, more time domain resources and/or more frequency domain resources, and under an internet of things service, the SPS PDSCH may have a shorter period, and less time domain resources and/or less frequency domain resources. In fig. 4, SPS PDSCH with two configurations, namely PDSCH of SPS configuration 1 and PDSCH of SPS configuration 2, are shown. The periodicity of the SPS PDSCH may be one or more subframes, one or more slots, one or more sub-slots, or R time domain symbols, etc. R is an integer greater than or equal to 1.

One or more configured SPS PDSCH may be included in the same time domain resource, e.g., PDSCH of SPS configuration 1 and PDSCH of SPS configuration 2 in Slot n or Slot n+1 as shown in fig. 4. In an implementation, the network device may indicate SPS activation of different configurations through different DCIs.

The feedback information of the M SPS PDSCH may be sequentially arranged, for example, the feedback information of the M SPS PDSCH may be sequentially arranged based on at least one of: the sequence of time, the sequence from small to large of the HARQ process number of the SPS PDSCH, the sequence from small to large of the SPS configuration number, the sequence from small to large of the carrier number of the carrier where the SPS PDSCH is located, and the like. For example, the time domain position of the first SPS PDSCH is before the time domain position of the second SPS PDSCH, then the first SPS PDSCH is concatenated before the second SPS PDSCH. For another example, the time domain position of the first SPS PDSCH is the same as the time domain position of the second SPS PDSCH, however, the HARQ process number of the first SPS PDSCH is less than the HARQ process number of the second SPS PDSCH, and the first SPS PDSCH is concatenated before the second SPS PDSCH.

In some embodiments, feedback information of any one SPS PDSCH (or feedback information corresponding to any one SPS PDSCH) among feedback information of M SPS PDSCH may be ACK/NACK information or HARQ-ACK information.

S502, determining target feedback information from a feedback information set; the target feedback information includes: feedback information of the first N SPS PDSCHs in feedback information of the M SPS PDSCHs; n is an integer greater than or equal to 1 and less than or equal to M.

In case that M is 1, the feedback information of the first N SPS PDSCH may be the feedback information of the 1 SPS PDSCH.

In some embodiments, the feedback information of the first N SPS PDSCHs may be feedback information of the M SPS PDSCHs that is earlier in time, and/or feedback information of the SPS PDSCHs that is earlier in hybrid automatic repeat request HARQ process number, and/or feedback information of the SPS configuration number that is earlier in time, and/or feedback information of the carrier on which the SPS PDSCH is located that is earlier in time.

S503, transmitting target feedback information on the first time domain resource.

The terminal device may transmit the target feedback information on the PUCCH corresponding to the first time domain resource. For example, the terminal device may transmit the target feedback information on a certain PUCCH in the first time domain resource. The terminal device may send target feedback information to the network device on the first time domain resource.

In some embodiments, only the target feedback information may be transmitted in a certain PUCCH of the first time domain resource. In other embodiments, not only the target feedback information but also other control information may be transmitted in a certain PUCCH of the first time domain resource, which is not limited by the embodiment of the present application.

The first time domain resource may be configured with one or more PUCCH resources, e.g., the first time domain resource may be configured with PUCCH resources of at least one of: a first PUCCH resource, a second PUCCH resource, a third PUCCH resource, and a fourth PUCCH resource. In other embodiments, more than four PUCCH resources may be configured in the first time domain resource.

The attribute information of different PUCCH resources may be different in any one time domain resource (including the first time domain resource). The attribute information of the same PUCCH resource configured in different time domain resources may be the same. The attribute information may include at least one of occupied time domain resources, occupied frequency domain resources, and the number of bits that can be carried. For example, as shown in fig. 4, the attribute information of PUCCH 1 and PUCCH 2 in slot+3 may be different, and in slot+3 and slot+5, the attribute information of two PUCCHs 1 may be the same, and the attribute information of two PUCCHs 2 may be the same.

In some embodiments, if there are no resources on the first time domain resources capable of transmitting the target feedback information, for example, the first time domain resources do not include uplink resources and/or flexible resources, or the first time domain resources may include not only uplink resources and/or flexible resources but also unavailable resources, and the PUCCH in the first time domain resources includes unavailable resources (i.e., resources that cannot be used to transmit feedback information, where embodiments in which the PUCCH includes unavailable resources may include resources corresponding to the PUCCH being all or part of unavailable resources), the terminal device will not transmit the target feedback information on the first time domain resources, thereby delaying the feedback resource set from being transmitted on one or more time domain resources after the first time domain resources.

In some embodiments, the set of feedback information may include: deferred first feedback information associated with a first time domain resource; the first feedback information includes: determining specified feedback information transmitted on the second time domain resource based on the time domain offset; the second time domain resource precedes the first time domain resource, and no resources for transmitting the specified feedback information are available in the second time domain resource.

The second time domain resource may comprise one time domain resource or a plurality of time domain resources. The second time domain resource may be a contiguous time domain resource with the first time domain resource, or the second time domain resource may be spaced apart from the first time domain resource by one or more time domain resources.

As shown in fig. 4, taking the first time domain resource as Slot n+3 as an example, feedback information of the SPS PDSCH 0 and the SPS PDSCH 1, which can be determined based on the time domain offset, is transmitted in Slot n+1, but the Slot n+1 is a downlink Slot, and if the feedback information cannot be transmitted, the corresponding feedback information (feedback information of the SPS PDSCH 0 and the SPS PDSCH 1) needs to be deferred. Feedback information of the SPS PDSCH 2 and the SPS PDSCH 3 is transmitted in the Slot n+2, however, the Slot n+2 is a downlink Slot, and the feedback information cannot be transmitted, and the corresponding feedback information (feedback information of the SPS PDSCH 0-3) needs to be deferred until the Slot n+3. The feedback information of SPS PDSCH 0, SPS PDSCH 1, SPS PDSCH 2, and SPS PDSCH 3 may thus be determined as deferred first feedback information associated with the first time domain resource.

In other embodiments, the set of feedback information may include: non-deferred second feedback information associated with the first time domain resource; the second feedback information includes: feedback information transmitted on the first time domain resource determined based on the time domain offset.

As shown in fig. 4, taking the first time domain resource as Slot n+3 as an example, feedback information of the SPS PDSCH 4 and the SPS PDSCH 5, which can be determined based on the time domain offset, is transmitted in Slot n+3, so that the feedback information of the SPS PDSCH 4 and the SPS PDSCH 5 can be determined as non-deferred second feedback information associated with the first time domain resource.

In still other embodiments, the set of feedback information may include: the feedback information set includes: deferred first feedback information associated with the first time domain resource, and non-deferred second feedback information associated with the first time domain resource.

In some embodiments, differently configured SPS PDSCH may correspond to different time domain offsets.

As shown in fig. 4, according to the data transmission method provided by the embodiment of the present application, PUCCH resources used for transmitting feedback information of an SPS PDSCH in a first time domain resource may include PUCCH 1 and PUCCH 2, where the time domain resource occupied by PUCCH 1 is an uplink resource, and feedback information of the SPS PDSCH may be transmitted, so that based on that the number of bits that can be carried by PUCCH 1 is 2, it is determined that the target feedback information includes feedback information of SPS PDSCH 0 and SPS PDSCH 1. The time domain resource occupied by PUCCH 2 is feedback information including unavailable resources (e.g., downlink resources) to which SPS PDSCH may not be transmitted.

In some embodiments, the first target resource for transmitting the target feedback information in the first time domain resource is a resource corresponding to a target number of bits; the target bit number belongs to the bit number which can be borne by one or more uplink resources respectively, the target bit number is closest to the bit number of the feedback information set, and the target bit number is greater than or equal to the bit number of the feedback information set; the one or more uplink resources are uplink resources available in the first time domain resource for transmitting feedback information.

In other embodiments, the first target resource used for transmitting the target feedback information in the first time domain resource may be a resource corresponding to a maximum number of bits in the number of bits that may be respectively carried by one or more available uplink resources, where the number of bits that may be carried by the first target resource is less than or equal to the number of bits of the feedback information set.

It should be noted that one or more uplink resources mentioned in any of the embodiments of the present application may be available resources for transmitting uplink data. The symbols occupied or corresponding by the available resources for transmitting uplink data may be uplink symbols, or may be uplink symbols and/or flexible symbols. The uplink symbols and/or flexible symbols may be semi-statically configured or may be dynamically indicated.

In an implementation process, feedback information of the first N SPS PDSCH may be determined based on the time domain resource as a minimum unit. For example, the feedback information of the first N SPS PDSCH may be feedback information of all SPS PDSCH in one or more time domain resources.

The feedback information of the M SPS PDSCH includes: feedback information for all SPS PDSCH in one or more time domain resources preceding and associated with the first time domain resource.

The feedback information of the first N SPS PDSCH includes: feedback information of all SPS PDSCH in the first P time domain resources of the one or more time domain resources; p is an integer greater than or equal to 1.

Fig. 6 is a schematic implementation flow chart of another data transmission method provided in an embodiment of the present application, where, as shown in fig. 6, the method is applied to a terminal device, and the method includes:

s601, acquiring a feedback information set associated with a first time domain resource; the feedback information set includes: feedback information of the PDSCH of the M semi-persistent scheduling SPS physical downlink shared channels; m is an integer greater than or equal to 1.

S602, determining feedback information of all SPS PDSCH in the first P time domain resources of one or more time domain resources in a feedback information set, corresponding to a second target resource, wherein the second target resource is allowed to be transmitted in the first time domain resource; one or more time domain resources precede and are associated with the first time domain resource.

In any of the embodiments of the present application, one or more time domain resources associated with the first time domain resource may be determined based on the time domain offset. In some embodiments, the one or more time domain resources associated with the first time domain resource may be time domain resources where all SPS PDSCH corresponding to each feedback information in the feedback information set associated with the first time domain resource are located.

In this step, the second target resource is allowed to transmit in the first time domain resource, and may include: data on the second target resource (including feedback information of all SPS PDSCH in the first P time domain resources) is allowed to be transmitted in the first time domain resource, and/or the second target resource is an uplink transmission resource and/or a flexible transmission resource.

One embodiment in which the second target resource is allowed to transmit in the first time domain resource may be: the bit number of feedback information of all SPS PDSCH in the first P time domain resources is smaller than or equal to the bit number which can be borne by the second target resource, and the second target resource is an uplink resource and/or a flexible resource.

The uplink resource mentioned in the embodiment of the present application may refer to that the symbol occupied by the resource is an uplink symbol, and the flexible resource may refer to that the symbol occupied by the resource is a flexible symbol.

S603, determining feedback information of all SPS PDSCH in the first P+1 time domain resources of one or more time domain resources, wherein the feedback information corresponds to a third target resource, and the third target resource is not allowed to be transmitted in the first time domain resource; the third target resource may carry a greater number of bits than the second target resource.

In some embodiments, the third target resource not being allowed to transmit in the first time domain resource may include: the bit number of feedback information of all SPS PDSCH in the first P+1 time domain resources is larger than the bit number which can be carried by the third target resource; alternatively, the third target resource comprises an unavailable resource.

For example, the number of bits of feedback information of all SPS PDSCH in the first p+1 time domain resources is 4 bits, but the number of bits that the third target resource can carry is 2 bits, thereby determining that the third target resource is not allowed to transmit in the first time domain resource.

In an embodiment of the present application, the unavailable resources may include at least one of: downlink resources, uplink and downlink handover protection resources, unavailable resources of network configuration. Symbols occupied by unavailable resources can include downlink symbols, uplink and downlink handover protection symbols, and network configured unavailable symbols. The downlink symbols may include semi-statically configured downlink symbols, or semi-statically and dynamically configured downlink symbols.

S604, determining feedback information of all SPS PDSCH in the first P time domain resources as target feedback information.

S605, transmitting target feedback information on the first time domain resource.

Taking fig. 4 as an example, an embodiment corresponding to fig. 6 is illustrated, in fig. 4, PUCCH resource 1 may carry 2 bits, and PUCCH resource 2 may carry 7 bits.

Feedback information of the SPS PDSCH 0 and the SPS PDSCH 1 in the Slot n is transmitted in the Slot n+1, but the Slot is a downlink time Slot, and the feedback information cannot be transmitted, so that the corresponding feedback information needs to be deferred. Feedback information of the SPS PDSCH 2 and the SPS PDSCH 3 in the Slot n+1 is transmitted in the Slot n+2, but the Slot is a downlink time Slot, and the feedback information cannot be transmitted, so that the corresponding feedback information needs to be deferred. Feedback information of the SPS PDSCH 4 and the SPS PDSCH 5 in Slot n+2 is transmitted in Slot n+3.
