Description

Data transmission method and data transmission device

Technical Field

The present application relates to the field of communications, and in particular, to a data transmission method and a data transmission apparatus.

Background

With the rapid increase of communication traffic, the licensed band in the network is not more and more satisfied with the increasing traffic, and in order to further improve the frequency resource benefit efficiency on the limited frequency resources, the third generation partnership project (3 GPP) organizes the research of access technology to the unlicensed band.

At present, a new radio unlicensed spectrum (NR-U) system supports two Channel Occupancy Time (COT) initialization modes, one is a COT initialized by a network device, and the other is a COT initialized by a terminal device. Under the condition that the COT initialized by the network device and the COT initialized by the terminal device (triggered by the dynamic uplink scheduling transmission) overlap in time, if the COT successfully initialized by the terminal device is earlier in time than the COT initialized by the network device, the network device cannot initialize the COT and cannot schedule other terminal devices. Because the COT initialized by the terminal device can only be used for transmission between itself and the network device, other terminal devices cannot perform uplink transmission with the network device within the COT, which results in a decrease in resource utilization rate and a decrease in throughput of the whole system.

It should also be understood that fig. 1 is a simplified schematic diagram that is shown only for ease of understanding, and that other devices, not shown in fig. 1, may also be included in the communication system 100.

With the rapid increase of communication traffic, the authorized frequency band in the network is not more and more satisfied with the increasing traffic, and in order to further improve the frequency resource on the limited frequency resource to facilitate efficiency, the 3GPP organization turns to the access technology research of the unauthorized frequency band.

At present, two COT initialization modes are supported in an NR-U system, one is a COT initialized by a network device, and the other is a COT initialized by a terminal device, under the condition that the COT initialized by the network device and the COT initialized by the terminal device (triggered by dynamic uplink scheduling transmission) overlap in time, if the COT initialized successfully by the UE is earlier than the COT initialized by the network device in time, the network device cannot initialize one COT, so that other terminal devices cannot be scheduled. Because the COT initialized by the terminal device can only be used for transmission between itself and the network device, other terminal devices cannot send uplink transmission within the COT, and if the terminal device occupies a channel for a long time through the initialized COT, this may cause that the entire network device serving cell cannot work normally and the transmission fairness in the cell cannot be guaranteed, and also cause a decrease in resource utilization rate and a decrease in throughput of the entire system.

Currently, 5G NR-U defines two types of devices, one type being frame based devices (FBE) and the other type being load based devices (LBE). For FBE, a period is set, and channel detection is performed once at a fixed position of each period, for example, CCA detection is performed during each Clear Channel Assessment (CCA) detection time. If the channel state is detected to be idle, the channel can be occupied for transmission; if the channel state is detected to be non-idle, the device cannot occupy the channel in the period until the fixed position of the next period is waited to continue to detect. If the CCA is performed for interference detection in each period, a large processing overhead is incurred for the device, and the success rate of accessing the channel cannot be guaranteed. For FBE, two ways of initiating COT are currently supported, including network device initiated COT and terminal device initiated COT. For the condition that a dynamic uplink scheduling transmission schedules at least one Physical Uplink Shared Channel (PUSCH), how the network device controls the FFP of the terminal device avoids the problem of conflict between the terminal device initialization COT and the network device initialization COT, and at present, no mechanism exists to enable the network device to control UE (user equipment) to initialize COT.

In view of this, the present application provides a data transmission method and a data transmission apparatus, where a network device sends at least one PUSCH and indication information for initializing a COT to a terminal device, and the terminal device can send uplink data on an FFP that allows the initiation of the COT according to the scheduling information and the indication information, so as to avoid a collision problem between the terminal device initialization COT (triggered by dynamic uplink scheduling transmission) and the network device initialization COT, which is beneficial to improving resource utilization rate and also improves throughput of the entire system.

Before describing the data transmission method and the data transmission apparatus provided in the embodiments of the present application, the following description is made.

First, in the embodiments shown below, terms and english abbreviations such as COT, transmission configuration pattern, etc. are exemplary examples given for convenience of description, and should not limit the present application in any way.

Second, the first, second and various numerical numbers in the embodiments shown below are merely for convenience of description and are not intended to limit the scope of the embodiments of the present application. For example, different information is distinguished, different indication information is distinguished, and the like.

"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Illustratively, "0" indicates that the network device does not allow the terminal device to initialize the COT on the FFP, and "1" indicates that the network device allows the terminal device to initialize the COT on the FFP; alternatively, "1" indicates that the network device does not allow the terminal device to initialize the COT on the FFP, and "0" indicates that the network device allows the terminal device to initialize the COT on the FFP.

S203, the network device sends second information to the terminal device, where the second information is used to schedule the at least one PUSCH. Accordingly, the terminal device receives the second information from the network device.

It should be understood that the second information may be indication information carried by the network device through the DCI, and the indication information may be used for scheduling at least one PUSCH.

And S204, the terminal equipment sends uplink data to the network equipment on the FFP of the initialized COT based on the second information. Correspondingly, the network equipment receives the uplink data sent by the terminal equipment based on the second information.

As an alternative embodiment, after the network device determines the first configuration (i.e., S202), the network device sends the first information to the terminal device based on the first configuration. Accordingly, the terminal device receives the first information from the network device. The first information is used for indicating whether the terminal device is allowed to initialize a channel occupation time COT on N FFPs occupied by at least one PUSCH, wherein N is an integer greater than or equal to 1; the terminal device determines the first configuration based on the first information.

It should be understood that the first information may be configured by the network device for the terminal device through RRC, or may be configured by the network device for the terminal device through DCI or other signaling, which is not limited in this embodiment of the present application.

It should also be understood that if the first information indicates that the terminal device is allowed to initialize the COT on the FFP, the COT may be initialized by the terminal device; if the first information indicates that the terminal device is not allowed to initialize the COT on the FFP, the COT can be initialized by the network device.

As an optional embodiment, the first information includes first indication information with a bit, where the first indication information is used to indicate whether the terminal device is allowed to initialize the COT on the N FFPs, or the first indication information is used to indicate whether the terminal device is allowed to initialize the COT on a first FFP of the N FFPs.

In a possible implementation manner, the first information indicates whether the terminal device is allowed to initialize the COT on the N FFPs by using one-bit indication information. The first indication information is '0', which indicates that the network equipment does not allow the terminal equipment to initialize COTs on the N FFPs; the first indication information is "1", which indicates that the network device allows the terminal device to initialize the COT on the N FFPs. Or, the first indication information is "0", which indicates that the network device allows the terminal device to initialize the COT on the N FFPs; the first indication information is "1", which indicates that the network device does not allow the terminal device to initialize the COT on the N FFPs.

In another possible implementation manner, the first indication information may indicate, by using one-bit indication information, whether the terminal device is allowed to initialize a COT on a first FFP of the N FFPs. The one bit is "0", which indicates that the network device does not allow the terminal device to initialize the COT on the first FFP of the N FFPs; the bit is "1" indicating that the network device allows the terminal device to initialize the COT on the first FFP of the N FFPs. Or, the bit is "0", which indicates that the network device allows the terminal device to initialize the COT on the first FFP of the N FFPs; the one bit is "1" indicating that the network device does not allow the terminal device to initialize the COT on the first FFP of the N FFPs. The other FFPs of the N FFPs may perform corresponding operations through semi-static configuration.

It should be understood that the indication manner of the semi-static configuration may be configured according to the indication manner of the first information. The detailed configuration is not described herein.

Illustratively, the network device may periodically indicate FFPs for a plurality of terminal devices through a semi-static configuration (1011). In a case that the one-bit indication information only indicates whether the terminal device is allowed to initialize the COT on the first FFP of the N FFPs, the other FFPs of the 4 FFPs may perform corresponding operations according to the indication methods of (101), (011), (111), or (110), and specifically, what indication method is adopted may be determined according to the position where the first FFP indicated by the first information is located. For example, the first FFP indicated by the first information is the 1 st FFP in the semi-static configuration (1011) corresponding to the 4 FFPs, the 1 st FFP may operate according to the first indication information, and the 2 nd to 4 th FFPs may perform corresponding operations in a (011) manner.

As an optional embodiment, the first information includes N-bit second indication information, where the second indication information is used to indicate whether to allow the terminal device to initialize a COT on the N FFPs.

In this embodiment, the number of bits of the second indication information is equal to the number of the FFPs, that is, the present embodiment adopts a bitwise manner to indicate one by one, and each of the N bits indicates whether to allow the terminal device to initialize the COT on each of the N FFPs.

Illustratively, the first information may include three-bit second indication information (101) for indicating whether the network device allows the terminal device to initialize the COT on 3 FFPs. Assuming that "1" indicates that the network device allows the terminal device to initialize the COT on the FFP, and "0" indicates that the network device does not allow the terminal device to initialize the COT on the first FFP of the N FFPs, the terminal device may determine that on these 3 FFPs, the network device allows the terminal device to initialize the COT on the 1 st FFP and the 3rd FFP, and the network device does not allow the terminal device to not initialize the COT on the 2 nd FFP.

As an optional embodiment, the first information includes third indication information, where the third indication information is used to indicate an index of a first transmission configuration pattern in the M transmission configuration patterns; before the network device sends the first information to the terminal device based on the first configuration, the method 200 further includes:

the network device sends third information to the terminal device, where the third information is used to indicate the M transmission configuration patterns, where the transmission configuration patterns include indication information of whether to allow the terminal device to initialize a COT on each FFP of the N FFPs, and M is an integer greater than or equal to 1. Accordingly, the terminal device receives the third indication information.

In step S201, the terminal device determines the first configuration, including: the terminal device determines the first transmission configuration pattern based on the third information and the third indication information; the terminal device determines the first configuration based on the first transmission configuration pattern.

It should be understood that, when the terminal device receives the third indication information, a first transmission configuration pattern corresponding to the index indicated by the third indication information may be matched from the M transmission configuration patterns, and then the terminal device may determine whether to initialize the COT on the N FFPs based on the first transmission configuration pattern.

In a possible implementation manner, the third information is configured by the network device through higher layer signaling, i.e., semi-statically configured, and the first information is sent by the network device through physical layer signaling, i.e., sent when the PUSCH is dynamically scheduled. Therefore, the embodiment of the application is beneficial to saving the signaling overhead of the dynamic scheduling of the PUSCH by the network equipment through a joint indication mode, thereby improving the system performance.

As an optional embodiment, the third information is radio resource control RRC information, and the first information and the second information are downlink control information DCI.

As an optional embodiment, after the network device sends the first information to the terminal device based on the first configuration, the method 200 further includes:

the network device sends fourth information to the terminal device, where the fourth information includes fourth indication information, and the fourth indication information is used to indicate an index of a second transmission configuration pattern in the M transmission configuration patterns. Accordingly, the terminal device receives the fourth information from the network device. The terminal device determines a first configuration, including: the terminal device determines the second transmission configuration pattern based on the third information and the fourth indication information; the terminal device determines the first configuration based on the second transmission configuration pattern.

It should be understood that, in the configuration process of the terminal device determining the second transmission configuration pattern based on the third information and the fourth indication information, the determination process of the first transmission configuration pattern may be referred to, and details are not described herein again.

In this embodiment, in the process of sending uplink data transmission, the terminal device receives new indication information (i.e., the fourth indication information) indicating a new transmission configuration pattern index (i.e., the index of the second transmission configuration pattern), and in this case, the terminal device may send subsequent data of uplink data transmission according to the new transmission configuration pattern index.

As an optional embodiment, after the network device sends the first information to the terminal device based on the first configuration, the method further includes:

the network device sends fifth information to the terminal device, where the fifth information is used to indicate whether the terminal device is allowed to initialize a COT on the N FFPs. Accordingly, the terminal device receives the fifth information from the network device. The terminal device determines a first configuration, including: the terminal device determines that it is the above-described first configuration based on the fifth information.

Optionally, the fifth information may indicate the N FFPs according to the indication manner of the first indication information, and the specific indication manner may refer to the description related to the first indication information, which is not described herein again.

Optionally, the fifth information may indicate the N FFPs according to the indication manner of the second indication information, and the specific indication manner may refer to the description related to the second indication information, which is not described herein again.

It should be understood that the fifth information is used to update the indication states of the first indication information and the second indication information for the N FFPs. The starting point of the fifth information validation may be the first symbol of the FFP occupied by the first PUSCH of the dynamic scheduling.

As an optional embodiment, the first information is semi-static indication information, and the second information does not carry indication information indicating whether to allow the terminal device to initialize the COT on the N FFPs; the terminal equipment determines a first configuration, and comprises the following steps: the terminal device determines the first configuration based on the first information.

As an optional embodiment, the first information is semi-static indication information, and the second information carries indication information indicating whether to allow the terminal device to initialize the COT on the N FFPs; the terminal equipment determines a first configuration, and comprises the following steps: the terminal device determines the first configuration based on the second information.

In this embodiment of the present application, for the same FFP or the same group of FFPs, when the first information is semi-persistent scheduling information and the second information does not carry indication information indicating whether to allow the terminal device to initialize a COT on N FFPs, the terminal device may determine whether to initialize a COT on N FFPs according to the semi-persistent scheduling information (i.e., the first information). If the second information carries indication information indicating whether the terminal device is allowed to initialize the COT on the N FFPs, the indication may be performed according to the indication of the second information.

As an alternative embodiment, the terminal device and the network device may determine the first configuration based on predefined rules. The predefined rules include any of the following: allowing the terminal device to initialize COT on N FFPs occupied by at least one scheduled PUSCH; not allowing the terminal device to initialize COT on N FFPs occupied by at least one scheduled PUSCH; allowing the terminal device to initialize COT on a first FFP in N FFPs occupied by at least one scheduled PUSCH; or, the terminal device is not allowed to initialize the COT on the first FFP of the N FFPs occupied by the scheduled at least one PUSCH.

It should be appreciated that the predefined rule may be a transport protocol configured through RRC signaling or otherwise.

The following takes a 5G NR-U system as an example, and details the data transmission method provided in the embodiments of the present application are described with reference to five specific embodiments.

It should be understood that in fig. 13 to 21, the network device is the gNB and the terminal device is the UE 1. Here, UE1 represents one terminal device capable of communicating with the gNB, and UIC represents permission indication information for UE to initialize COT, which corresponds to the first information.

Example one

When the network device dynamically schedules a plurality of PUSCHs (one transmission bundle) to occupy one or a plurality of FFPs for transmission, the DCI indicates whether the terminal device is allowed to initialize (initiated) COT on the FFPs occupied by the dynamically scheduled PUSCHs through 1 bit.

In one possible embodiment, a 1-bit indication of "1" indicates that the terminal device is allowed to initialize a COT on one or more FFPs; a 1bit indication of "0" indicates that the terminal device is not allowed to initialize the COT on one or more FFPs.

Fig. 3 and fig. 4 are schematic diagrams illustrating that a 1bit is used to indicate whether a terminal device is allowed to initialize a COT on multiple FFPs according to an embodiment of the present application.

As shown in fig. 3, when 3 PUSCH are dynamically scheduled to occupy 3 FFPs of UE, DCI indication information is "1", which represents that UE1 is allowed to initialize COT on 3 FFPs. At this time, the dynamically scheduled 3 PUSCHs may utilize COT initialized by the UE1 for data transmission.

As shown in fig. 4, when 3 PUSCH are dynamically scheduled to occupy 3 FFPs, the indication information carried in the DCI is "0", which means that the UE1 is not allowed to initialize COT on the 3 FFPs. At this time, 3 FFPs occupied by the dynamically scheduled 3 PUSCHs need to use the gNB initialization COT for data transmission. If the gNB can successfully initialize one COT, the UE1 sends uplink data at the corresponding gNB FFP where the gNB initialized COT is located.

Fig. 5 shows another schematic diagram that indicates whether to allow the terminal device to initialize the COT on 1 FFP by using 1bit according to the embodiment of the present application. As shown in fig. 5, when 3 PUSCHs dynamically scheduled by the network device occupy 1 FFP, the DCI indication information is "1", which represents that the UE1 is allowed to initialize COT on 1 FFP. At this time, the dynamically scheduled 3 PUSCHs may utilize the UE1 to initialize COT for data transmission.

In another possible embodiment, when the FFP of the terminal device has a semi-static configuration, a 1-bit indication of "1" indicates that the terminal device is allowed to initialize the COT at the first FFP where the PUSCH is located in one transmission bundle; other FFPs are performed according to a semi-statically configured FFP pattern (pattern). The 1-bit indication is "0" to indicate that the terminal device is not allowed to initialize the COT in the first FFP where the PUSCH is located in one transmission bundle, and other FFPs are executed according to the semi-static configuration pattern.

Fig. 6 and fig. 7 show schematic diagrams of still another method for indicating whether to allow a terminal device to initialize a COT on multiple FFPs by using 1bit according to an embodiment of the present application.

As shown in fig. 6, when 3 PUSCH is dynamically scheduled to occupy 3 FFPs of a UE, DCI indication information is "1", and since the FFP of the UE1 has a semi-static configuration, only the UE1 is allowed to initialize a COT on the 1 st FFP, and the 2 nd and 3rd FFPs occupied by the 2 nd and 3rd PUSCH are executed according to the semi-static configured "1" and "0", that is, the UE1 is not allowed to initialize a COT on the 2 nd FFP, at this time, it is necessary to initialize one COT by using the gNB, and the gNB successfully initializes one COT. The 2 nd PUSCH is data that can be transmitted.

As shown in fig. 7, when 3 PUSCH is dynamically scheduled to occupy 3 UE FFPs, DCI indication information is "1", since the FFP of the UE1 has a semi-static configuration, only the 1 st FFP allows the UE1 to initialize, the 2 nd and 3rd FFPs occupied by the 2 nd and 3rd PUSCH are executed according to "1" and "0" of the semi-static configuration, that is, the UE1 is not allowed to initialize COT at the 2 nd FFP, and the gNB does not initialize COT, so the 2 nd PUSCH cannot transmit data.

Example two

The network device dynamically schedules a plurality of PUSCHs (one transmission bundle) to occupy one or more FFP transmissions through the DCI.

In a possible implementation manner, the DCI carries N bits of indication information for indicating whether to allow the terminal device to initialize the COT on the FFP occupied by the multiple PUSCHs dynamically scheduled by the network device. Wherein, the N bits may directly indicate, in a bitmap (bitmap) manner, whether to allow the terminal device to initialize the COT in each of the FFPs occupied by one transmission bundle, and if each bit in the N bits is "1", it indicates that the terminal device is allowed to initialize the COT in the corresponding UE FFP; if each bit in the N bits is "0", it indicates that the terminal device is not allowed to initialize the COT at the corresponding FFP.

Fig. 8 shows a schematic diagram that indicates whether to allow a terminal device to initialize a COT on multiple FFPs by using multiple bits according to an embodiment of the present application. As shown in fig. 8, when 3 PUSCHs occupy 3 FFPs in dynamic scheduling, the indication information carried by the DCI is 3 bits (101), which directly indicates whether the whole transmission bundle allows the UE-initiated COT, and it can be known according to the indication rule that the 2 nd FFP where the second PUSCH is scheduled in the DCI is the UE-initiated COT which is not allowed, the gNB needs to be used to initialize the COT, and the gNB successfully initializes one COT, so that the PUSCH can perform data transmission on the FFP where the gNB-initiated COT is located.

In another possible embodiment, the DCI simultaneously carries an index of a transmission pattern list.

Specifically, first, the gNB issues a transmission pattern list (the list includes different transmission pattern indications from 1 FFP to N FFPs, which are M types) to the UE through a higher layer signaling (e.g., an RRC signaling); secondly, the gNB sends a transmission pattern index (the occupied bit is log2(M)) through the DCI according to the FFP number occupied by the PUSCH dynamically scheduled by the DCI and the collision avoidance strategy; finally, the terminal device may determine whether to initialize the COT on the FFP occupied by the PUSCH dynamically scheduled by the DCI according to the transmission pattern list index indicated by the DCI and the transmission pattern list configured by the higher layer signaling.

Table one shows a transmission pattern list of RRC configuration whether the terminal device is allowed to initialize COT on multiple FFPs.

Watch 1

As shown in table one, when 3 PUSCHs occupy 3 FFPs in dynamic scheduling, the DCI matches the behavior corresponding to the index number in the transmission list by indicating the index number of the transmission pattern list. For example, the DCI passes a third row (101) indicating (10) a corresponding transmission list.

Fig. 9 is a schematic diagram illustrating another example of indicating whether to allow a terminal device to initialize a COT on multiple FFPs according to an embodiment of the present application. As shown in fig. 9, the index number of the DCI indication is 10. With reference to the table one, the transmission pattern list corresponding to the index number "10" is (101). Therefore, the UE1 is not allowed to initialize COT on the 2 nd FFP where the 2 nd PUSCH of DCI scheduling is located, and therefore the PUSCH needs to utilize the gNB initialization COT for data transmission.

It should be understood that, in the process of transmitting the bundle, if update indication information carried in the second DCI and indicating whether the terminal device is allowed to initialize the COT is received, subsequent transmission needs to be performed according to the update indication information.

Fig. 10 is a schematic diagram illustrating still another example of indicating whether to allow a terminal device to initialize a COT on multiple FFPs according to an embodiment of the present application. As shown in fig. 10, the indication information carried in the first DCI is 4bit (1011), which directly indicates whether the entire transmission bundle allows the UE1 to initialize the COT. However, in the transmission bundle, before the 3rd PUSCH, the update indication information (00) carried by the second DCI is received, which allows the UE1 to initialize the COT, so that the 3rd, 4 th, and 5th PUSCHs need to perform subsequent transmission according to the update indication information, that is, the 3rd PUSCH to the 5th PUSCH in the transmission bundle need to be transmitted by using the gNB-initiated COT.

EXAMPLE III

The embodiment mainly solves the problem that data transmission of dynamic scheduling and data transmission of semi-static scheduling are in the same FFP. If the DCI of the dynamic scheduling carries the indication of the initiation COT of the terminal equipment, the DCI is executed according to the indication of the dynamic scheduling DCI; and if the DCI does not carry the indication of the initialization COT of the terminal equipment, the terminal equipment executes the indication of the initialization COT according to the semi-static scheduling.

In an alternative embodiment, the gNB configures a transmission pattern (which may be periodic) through RRC signaling. When the gNB can dynamically schedule one PUSCH through the DCI, the gNB carries indication information at the same time, and the carried indication information replaces a transmission pattern configured by the signaling for the dynamic transmission. After the transmission is completed, the transmission pattern can be recovered to RRC signaling configuration to complete subsequent transmission; or directly using the indication information carried by the DCI to replace the transmission pattern configured by the signaling to complete the subsequent transmission.

Fig. 11 shows a schematic diagram of dynamically scheduled data transmission with semi-static scheduling conflict resolution. As shown in fig. 11, the gNB transmits a pattern (101101) through RRC configuration (the pattern is periodic). The gNB dynamically schedules the PUSCH and the gNB does not indicate a new transmission pattern through the DCI, when the dynamically scheduled PUSCH falls within the N +1 th UE FFP, the UE1 is not allowed to initialize the COT due to the fact that the transmission pattern indicates the N +1 th FFP; however, the PUSCH also falls within the mth gNB FFP, and the gNB successfully initializes the COT on the mth FFP, so the PUSCH can perform data transmission on the mth gNB FFP.

Fig. 12 shows a schematic diagram of another dynamically scheduled data transmission with semi-static scheduling conflict resolution. As shown in fig. 12, the gNB transmits a pattern (101101) through RRC configuration (the pattern is periodic). The gNB dynamically schedules the PUSCH and the gNB indicates a new transmission pattern through the DCI (i.e., the N +1 th FFP allows the UE1 to initialize COT), when the dynamically scheduled PUSCH falls within the N +1 th FFP, although the semi-statically configured transmission pattern indicates that the N +1 th UE FFP does not allow the UE1 to initialize COT, the DCI new indication information allows the UE1 to initialize COT at the N +1 th FFP. The PUSCH enables data transmission on the N +1 th UE FFP.

Fig. 13 shows a schematic diagram of still another dynamically scheduled data transmission and semi-static scheduling conflict resolution. As shown in fig. 13, the gNB configures a transmission pattern (101101) by RRC (the pattern is periodic), the gNB dynamically schedules PUSCH and indicates a new transmission pattern by DCI (i.e., the N +1 th FFP allows the UE1 to initialize COT), when the dynamically scheduled UL PUSCH of the gNB falls within the N-th UE FFP, although the semi-statically configured transmission pattern indicates the N-th UE FFP allows the UE-i to initialize COT, the new indication information of DCI does not allow the UE to initialize COT on the N-th FFP; however, the PUSCH also falls within the mth gNB FFP, and on the mth FFP, the gNB successfully initializes the COT, so the PUSCH can perform data transmission on the mth gNB FFP.

In another optional embodiment, if the gNB does not configure the transmission pattern, it is default that FFPs of all terminal devices can be used for the terminal device to initialize the COT, or that FFPs of all terminal devices cannot be used for the terminal device to initialize the COT.

Example four

When the network device dynamically schedules 1 PUSCH to occupy one or more FFP transmissions, the predefined rule may have the following two ways.

In one possible embodiment, the predefined rule is: the terminal device is allowed to initialize COT on one or more FFPs occupied by 1 PUSCH scheduled by the network device.

In one possible embodiment, the predefined rule is: allowing the terminal device to initialize COT on a first FFP in a plurality of FFPs occupied by 1 PUSCH scheduled by the network device, and performing corresponding operation on other FFPs in the plurality of occupied FFPs according to a semi-static configuration pattern, wherein if the semi-static configuration pattern allows the terminal device to initialize COT, the terminal device executes the operation of initializing COT; if the semi-static configuration pattern does not allow the terminal device to initialize the COT, the network device needs to be utilized to initialize the COT.

Fig. 14 shows a schematic diagram of terminal equipment initializing COT in the case that dynamic scheduling 1 PUSCH occupies 1 FFP. As shown in fig. 14, the gNB schedules one PUSCH with 3 repeated transmissions via DCI, which occupy 1 UE1 FFP. The predefined rule is to allow the UE1 to initialize a COT on 1 FFP occupied by 1 PUSCH scheduled by the gNB, and the UE1 FFP first repeats transmission at the beginning of the FFP. Therefore, the three repeated transmissions can be transmitted using UE1 to initialize the COT.

Fig. 15, 16, and 17 are diagrams illustrating that the terminal device initializes COT in the case where dynamic scheduling of 1 PUSCH occupies a plurality of FFPs.

As shown in fig. 15, the gNB schedules 1 PUSCH transmission with DCI, the 1 PUSCH transmission occupying 3 UEs 1 FFPs. The UE1 initializes the COT according to predefined rules. The predefined rule is to allow the UE1 to initialize the COT on multiple FFPs occupied by 1 PUSCH scheduled by the gNB, and three retransmissions (rep #0, rep #1 and rep #2) all start at 3 FFPs. Therefore, the three repeated transmissions can be transmitted using UE1 to initialize the COT.

As shown in fig. 16, the gNB schedules 1 PUSCH transmission through DCI, and the 1 PUSCH transmission occupies 3 UEs 1 FFP. The UE1 is performing whether to allow the UE1 to initialize COT according to the semi-static configuration pattern transmission rule. According to the semi-static configuration pattern (101), the following steps are carried out: of these 3 FFPs, only the 2 nd FFP does not allow UE1 to initialize the COT, so the 2 nd FFP can only initialize the COT with the gNB, while the other two FFPs allow UE1 to initialize the COT.

As shown in fig. 17, the gNB schedules 1 PUSCH transmission through DCI, and the 1 PUSCH transmission occupies 3 UEs 1 FFP. The UE1 initializes the COT according to predefined rules. The predefined rule is to allow the UE1 to initialize a COT on a first FFP of a plurality of FFPs occupied by 1 PUSCH scheduled by the gNB, and other FFPs of the plurality of occupied FFPs to initialize a COT according to a semi-static configuration pattern. Therefore, only the first FFP of the 3 UE1 FFPs allows the UE1 to initialize the COT, and the other two FFPs need to be executed according to the semi-static configuration pattern of (10). Therefore, FFP 1 does not allow UE1 to initialize COT (can only initialize COT with gNB), and FFP 2 allows UE1 to initialize COT.

EXAMPLE five

When the network device dynamically schedules multiple PUSCHs (one transmission bundle) to occupy one or multiple FFP transmissions, the predefined rule may have the following two ways.

In one possible implementation, the predefined rule is: one or more FFPs occupied by the terminal device on the multiple PUSCHs scheduled by the network device are allowed to allow the terminal device to initialize the COT.

In another possible implementation, the predefined rule is: allowing the terminal device to initialize COT at a first FFP of a plurality of FFPs occupied by a plurality of PUSCHs scheduled by the network device, and allowing other FFPs in the plurality of occupied FFPs to perform corresponding operations according to the semi-static configuration pattern. If the semi-static configuration pattern allows the terminal equipment to initialize the COT, the terminal equipment executes the operation of initializing the COT; if the semi-static configuration pattern does not allow the terminal device to initialize the COT, the network device needs to be utilized to initialize the COT.

Fig. 18 shows a schematic diagram of terminal equipment initializing COT in the case where dynamic scheduling of multiple PUSCHs occupies 1 FFP. As shown in fig. 18, the gNB schedules 3 PUSCH transmissions with DCI, the 3 PUSCH transmissions occupying 1 UE1 FFP. The predefined rule is: UE1 is allowed to initialize COT on 1 FFP occupied by multiple PUSCH scheduled by the gNB, and the 1 st PUSCH is at the beginning of the FFP. Therefore, the 3 PUSCHs can be transmitted using UE1 initialization COT.

Fig. 19, 20, and 21 are diagrams illustrating that the terminal device initializes the COT in the case where a plurality of PUSCHs are dynamically scheduled to occupy a plurality of FFPs.

As shown in fig. 19, the gNB schedules 3 PUSCH transmissions with DCI, the 3 PUSCH transmissions occupying 3 UEs 1 FFPs. The UE1 initializes the COT according to predefined rules. The predefined rules are: UE1 is allowed to initialize COT on multiple FFPs occupied by multiple PUSCHs scheduled by the gNB, and each PUSCH is at the beginning of an FFP. Therefore, the 3 PUSCHs can be transmitted using UE1 initialization COT.

As shown in fig. 20, the UE1 performs whether to allow the UE1 to initialize COT according to the semi-static configuration pattern transmission rule. According to the semi-static configuration pattern (101): of these 3 FFPs, only the 2 nd FFP is not allowed to UE initialize the COT, so the 2 nd FFP can only initialize the COT with the gNB, while the 1 st FFP and the 3rd FFP allow the UE1 to initialize the COT.

As shown in fig. 21, the gNB schedules 3 PUSCH transmissions with DCI, the 3 PUSCH transmissions occupying 3 UEs 1 FFPs. The UE1 initializes the COT according to predefined rules. The predefined rule is to allow the UE1 to initialize a COT on a first FFP of a plurality of FFPs occupied by the PUSCH scheduled by the gNB, and other FFPs of the occupied FFPs to initialize the COT according to the semi-static configuration pattern. Therefore, only the first FFP of the 3 UE1 FFPs allows the UE1 to initialize the COT, and the other two FFPs need to be executed according to the semi-static configuration pattern of (10). Therefore, FFP 2 does not allow UE1 to initialize COT (can only initialize COT with gbb), and FFP 3 allows UE1 to initialize COT.

It should be understood that, in the first to fifth embodiments, the PUSCH scheduled by the network device may also be replaced by a Physical Uplink Control Channel (PUCCH). For various situations when the network device schedules the PUCCH, reference may be made to the above description of the PUSCH, which is not described herein again.

It should also be understood that the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the inherent logic thereof, and should not constitute any limitation to the implementation process of the embodiments of the present application.

The data transmission method according to the embodiment of the present application is described in detail above with reference to fig. 2 to 21, and the data transmission device according to the embodiment of the present application is described in detail below with reference to fig. 22 to 23.

Fig. 22 is a schematic block diagram of a data transmission device 2200 provided in an embodiment of the present application. The apparatus 2200 comprises: a processing module 2210, a receiving module 2220, and a transmitting module 2230.

In a possible implementation manner, the apparatus 2220 is configured to execute each procedure and step corresponding to the terminal device in the foregoing method embodiment.
