Description

Data transmission method and device

Technical Field

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

Background

In the communication system, the network device instructs the terminal device to transmit time domain resources, frequency domain resources, coding modes, transmission power, frequency hopping sequences, resource mapping modes and the like used by uplink data in the first time slot through the first scheduling information. However, in some scenarios in the network, the terminal device may be caused to delay transmitting the uplink data on the first time slot.

For example, since there are low-latency high-reliability (URLLC) traffic data in the network, and these traffic data have burst and random characteristics, when the low-delay downlink service data arrives, the network device flexibly indicates the format information of at least one time slot through the Slot Format Information (SFI), the format information is used to indicate downlink symbols, unknown symbols, and uplink symbols in the time slot, and if the at least one time slot includes the first time slot, and the uplink symbol in the first time slot indicated by the time slot format information does not completely include the uplink symbol in the first time slot indicated by the first scheduling information, that is, the mapping and transmission of the uplink data cannot be completed according to the uplink symbol indicated by the first scheduling information, and at this time, the terminal device delays transmitting the uplink data on the first time slot.

Therefore, a solution is needed to solve the problem of how to transmit the data delayed by the terminal device.

Disclosure of Invention

The application provides a data transmission method and device, which can transmit data sent by terminal equipment in a delayed mode.

In a first aspect, the present application provides a method for data transmission, including:

the method comprises the steps that terminal equipment receives first scheduling information sent by network equipment, wherein the first scheduling information is used for indicating the terminal equipment to send first data in uplink time domain resources in a first time domain resource unit;

the terminal device delays transmitting the first data on the first time domain resource unit;

the terminal device receives control information sent by the network device, wherein the control information is used for triggering the data which is sent in a delayed manner on the first time domain resource unit and is sent on the second time domain resource unit;

the terminal equipment determines a target time domain resource unit according to the control information;

and the terminal equipment sends the first data to the network equipment on the target time domain resource unit.

In the data transmission method provided in the embodiment of the present application, when a terminal device delays sending data in a first time domain resource unit scheduled by a network device, the terminal device may receive control information sent by the network device, where the control information is used to trigger the terminal device to send the data delayed from the first time domain resource unit in a second time domain resource unit, and the data delayed from the terminal device may be transmitted.

In one possible implementation, the control information is different from at least one of the following of the first scheduling information: payload size, mapped resources, and scrambling sequence.

(1) Different scrambling sequence

The first scheduling information is DCI specific to the terminal device, and the network device may scramble the first scheduling information by using a scrambling sequence specific to the terminal device to obtain the specific DCI, and notify the terminal device of the scrambling sequence specific to the terminal device; accordingly, the terminal device may descramble the specific DCI according to the pre-configured terminal device-specific scrambling sequence to obtain the first scheduling information.

The control information is DCI common to the terminal group, the network device can scramble the control information through the scrambling sequence common to the terminal group to obtain the common DCI, and inform all the terminal devices in the terminal group of the specific scrambling sequence of the terminal group; accordingly, the terminal device in the terminal group may descramble the common DCI according to the pre-configured scrambling sequence common to the terminal group, so as to obtain the control information.

Optionally, because the control information is DCI common to the terminal group, when all the terminal devices in the terminal group delay sending the uplink data in the first time domain resource unit, the network device only needs to send the DCI common to the terminal group to the terminal devices, and then the terminal devices may be triggered to send the uplink data delayed to be sent in the first time domain resource unit in the second time domain resource unit, so that signaling overhead may be reduced.

Optionally, the multiple terminal devices may send uplink data on the uplink time domain resource in the first time domain resource unit through frequency division multiplexing or code division multiplexing, which is not limited in this embodiment of the present application.

(2) The mapped resources are different

The first scheduling information is mapped on the resources specific to the terminal device; accordingly, the terminal device searches on the control channel resource specific to the terminal device to obtain the first scheduling information.

The control information is mapped on the control channel resource common to the terminal group; accordingly, the terminal devices in the terminal group search on the control channel resource common to the terminal group to acquire the control information.

In the data transmission method provided in the embodiment of the present application, since the control information is mapped on the resource common to the terminal group, when the terminal device delays sending the first data on the first time domain resource unit, the terminal device only needs to search the control information on the control channel resource common to the terminal group, thereby reducing the search range of the terminal device.

(3) The payload size is different (i.e. the number of bits in the control information)

The first scheduling information is used to indicate at least one of information used for scheduling the terminal device, such as uplink frequency domain resources, uplink code domain resources, coding modes, transmission power and frequency hopping sequences, resource mapping modes, and the like, of the terminal device in the first time domain resource unit, and uplink time domain resources.

The indirect indication mode is as follows: the first time domain resource unit indication information is a scrambling sequence of the control information, and the scrambling sequence is associated with the identity of the first time domain resource unit, i.e. the scrambling sequence of the control information indicates the identity of the first time domain resource unit.

It is to be understood that the scrambling sequence is associated with the identity of the first time domain resource unit, which can be understood as the scrambling sequence is generated with the identity of the first time domain resource unit as a parameter of the generation function of the scrambling sequence.

In a possible implementation manner, the control information includes second time domain resource unit indication information, where the second time domain resource unit indication information includes an identifier of the second time domain resource unit or a time domain resource unit offset value, and the time domain resource unit offset value represents the number of time domain resource units between the first time domain resource unit and the second time domain resource.

Optionally, the control information may further include second time domain resource unit indication information, where the second time domain resource unit indication information may directly or indirectly indicate the second time domain resource unit, and this is not limited in this embodiment of the application.

Optionally, the control information may include the second time domain resource unit indication information, or may not include the second time domain resource unit indication information, that is, the network device may implicitly indicate the time domain resource unit used after the triggering, which is not limited in this embodiment of the present application.

As an optional embodiment, the terminal device may trigger to continue sending the first data, which is sent in a delayed manner over the first time domain resource unit, to the network device according to the received control information (excluding the second time domain resource unit indication information) sent by the network device, and determine the target time domain resource unit according to the identifier of the first time domain resource unit and a time domain resource unit offset value, where the time domain resource unit offset value represents the number of time domain resource units between the first time domain resource unit and the second time domain resource unit.

Optionally, the uplink time domain resource in the first time domain resource unit indicated by the time domain resource format information does not completely include the uplink resource in the first time domain resource unit indicated by the first scheduling information, and it can be understood that a part or all of the uplink time domain resource in the first time domain resource unit indicated by the first scheduling information is indicated as a downlink time domain resource or an unknown time domain resource in the time domain resource format information.

Optionally, when the terminal device determines that the uplink time domain resource in the first time domain resource unit is occupied or unavailable, the terminal device may also delay sending the first data on the first time domain resource unit.

In the data transmission method provided in the embodiment of the present application, since the control information is the common DCI of the terminal group, each terminal device in the terminal group may receive the control information, but in some scenarios, the control information is not applicable to individual terminal devices. At this time, the network device can reschedule the terminal device, and the flexibility of data transmission is improved.

S210, a network device sends first scheduling information to a terminal device, wherein the first scheduling information is used for indicating the terminal device to send first data in uplink time domain resources in a first time domain resource unit; accordingly, the terminal device receives the first scheduling information sent by the network device.

It should be understood that the embodiments of the present application are described by taking the example that the subcarrier interval is 15kHz, 1 subframe includes 1 slot, and 1 slot includes 14 symbols.

Optionally, the subcarrier interval in this embodiment may also be 30kHz, where 1 subframe includes 2 slots, and 1 slot includes 14 symbols, and the like, and this is not limited in this embodiment of the present application.

Optionally, the first time domain resource unit may be a slot (slot), a mini-slot (mini-slot), a symbol (symbol), a subframe (subframe), a system frame (frame), or the like, which is not limited in this embodiment.

As an optional embodiment, the first time domain resource unit may be a time slot, and the uplink time domain resource in the first time domain resource unit may be at least one symbol used for transmitting uplink data in the time slot.

For example, as shown in fig. 3, the first time domain resource unit may be the time slot 2 shown in fig. 3, and the uplink time domain resource in the first time domain resource unit may be the symbols 2 to 4 in the time slot 2.

As another optional embodiment, the first time domain resource unit may also be a subframe, the uplink time domain resource in the first time domain resource unit may be at least one symbol in the subframe, and when the uplink time domain resource in the first time domain resource unit is a plurality of symbols, the plurality of symbols may belong to the same time slot or different time slots, which is not limited in this embodiment of the present application.

It should be understood that the first scheduling information is also used to indicate at least one of information used for scheduling the terminal device, such as an uplink frequency domain resource, a coding method, a transmission power, a frequency hopping sequence, a resource mapping method, and the like used by the terminal device to transmit the first data on the first time domain resource unit, which is not limited in this embodiment of the present application.

As an optional embodiment, the first scheduling information may carry an identifier of the first time domain resource unit, an identifier of the uplink time domain resource in the first time domain resource unit, and an identifier of the uplink frequency domain resource in the first time domain resource unit.

For example, if the network device instructs the terminal device to transmit the first data on symbols 2 to 4 in slot 2 and Physical Resource Blocks (PRBs) 0 to 9 through the first scheduling information, the first scheduling information may carry an identifier of slot 2, an identifier of symbols 2 to 4 in slot 2, and an identifier of physical resource blocks 0 to 9.

Optionally, before S210, the terminal device may send a scheduling request to the network device, where the scheduling request is used to request the network device to allocate uplink resources for transmitting the first data.

Accordingly, S210 may be configured to send the first scheduling information to the terminal device according to the scheduling request for the network device.

S220, the terminal device delays sending the first data on the first time domain resource unit.

It should be understood that the terminal device delays sending the first data on the first time domain resource unit, which may be understood as the terminal device suspending the first data on the first time domain resource unit and waiting for triggering/activation, or rescheduling.

Optionally, there are multiple situations in the network that cause the terminal device to delay sending the first data on the first time domain resource unit, which is not limited in this embodiment of the present application.

As an optional embodiment, before S220, the network device may flexibly indicate format information of at least one time domain resource unit through time domain resource format information, where the format information of the time domain resource unit is used to indicate a downlink time domain resource, an unknown time domain resource, and an uplink time domain resource in the time domain resource unit. The downlink time domain resource is used for transmitting downlink data, the unknown time domain resource indicates that before other indication information about the part of time domain resource is not received, the terminal device is not used for transmitting uplink data or downlink data on the part of time domain resource, and the uplink time domain resource is used for transmitting uplink data. Wherein, the number of the uplink time domain resource, the unknown time domain resource, or the uplink time domain resource may be greater than or equal to 0.

For example, the time domain resource format information may indicate that all time domain resources in the first time domain resource unit are uplink time domain resources; or indicating all the time domain resources in the first time domain resource unit as downlink time domain resources; or indicating that a part of the time domain resources in the first time domain resource unit are downlink time domain resources, another part of the time domain resources are unknown time domain resources, and the remaining part of the time domain resources are uplink time domain resources, which is not limited in the embodiment of the present application.

Correspondingly, S220 may be that if the at least one time domain resource unit includes the first time domain resource unit and the uplink time domain resource in the first time domain resource unit indicated by the time domain resource format information does not completely include the uplink time domain resource in the first time domain resource unit indicated by the first scheduling information, the terminal device delays sending the first data on the first time domain resource unit.

Optionally, the time domain resource format information may be Downlink Control Information (DCI) common to the terminal group and carried on a Physical Downlink Control Channel (PDCCH), that is, the network device may indicate format information of the at least one time domain resource unit to all terminal devices in the terminal group through the time slot resource format information, where the terminal group includes the terminal device. Accordingly, all terminal devices in the terminal group can acquire the time domain resource format information.

In the data transmission method of the embodiment of the application, the time domain resource format information is downlink control information common to the terminal group, and all terminal devices in the terminal group can analyze the time domain resource format information, so that the network device does not need to send the time domain resource format information to each terminal device in the terminal group, and signaling overhead can be reduced.

It should be understood that the uplink time domain resource in the first time domain resource unit indicated by the time domain resource format information does not completely include the uplink resource in the first time domain resource unit indicated by the first scheduling information, and it may be understood that a part or all of the uplink time domain resource in the first time domain resource unit indicated by the first scheduling information is indicated as a downlink time domain resource or an unknown time domain resource in the time domain resource format information.

For example, as shown in fig. 4, the first scheduling information instructs the terminal device to transmit the first data on symbols 3 to 7 in slot 3 (e.g., in slot 3 indicated by the first scheduling information in fig. 4)

Shown); the time domain resource format information indicates that symbols 0 to 3 in the time slot 3 are downlink symbols (e.g., in the time slot 3 indicated by the time domain resource format information in fig. 4)

Shown), symbols 4 to 5 are unknown symbols (as indicated in time slot 3 by the time domain resource format information in fig. 4)

Shown), symbols 6-13 are uplink symbols (as indicated in time-domain resource format information in time slot 3 in fig. 4)

Shown).

For another example, as shown in FIG. 5, the first scheduling information indicates that the terminal device is in time slot 3The first data is transmitted on symbols 3-7 (e.g., in time slot 3 indicated by the first scheduling information in fig. 5)

Shown); the symbols 0 to 13 in the time slot 3 indicated by the time domain resource format information are all downlink symbols (e.g., in the time slot 3 indicated by the time domain resource format information in fig. 5)

Shown).

It should be further understood that, if at least one time domain resource unit includes the first time domain resource unit, and the uplink time domain resource in the first time domain resource unit indicated by the time domain resource format information includes the uplink time domain resource in the first time domain resource unit indicated by the first scheduling information, the terminal device may normally send the first data on the first time domain resource unit.

For example, as shown in fig. 6, the first scheduling information instructs the terminal device to transmit the first data on symbols 3 to 7 in slot 3 (e.g., in slot 3 indicated by the first scheduling information in fig. 6)

Shown); the time domain resource format information indicates that symbols 0 to 1 in the time slot 3 are downlink symbols (e.g., in the time slot 3 indicated by the time domain resource format information in fig. 6)

Shown), symbol 2 is an unknown symbol (as indicated in slot 3 by the time domain resource format information in fig. 6)

Shown), symbols 3 to 13 are uplink symbols (as indicated in time-domain resource format information in time slot 3 in fig. 6

Shown), the terminal device may be in the time slot 3 indicated by the first scheduling information from symbol 3 to symbolThe first data is transmitted at 7.

As another optional embodiment, when the terminal device determines that the uplink time domain resource in the first time domain resource unit is occupied or unavailable, the terminal device may also delay sending the first data on the first time domain resource unit.

S230, the network device determines that the terminal device delays sending the first data on the first time domain resource unit.

It should be understood that the method for the network device to determine that the terminal device delays sending the first data on the first time domain resource unit is the same as the method for the terminal device to determine that the terminal device delays sending the first data on the first time domain resource unit, and details are not described here to avoid repetition.

It should be understood that the execution order of S220 and S230 is not sequential.

S240, the network device sends control information to the terminal device, where the control information is used to trigger sending of data delayed in sending on the first time domain resource unit on the second time domain resource unit; accordingly, the terminal device receives the control information sent by the network device.

It should be understood that the control information is different from at least one of the following of the first scheduling information: scrambling sequence, mapped resources and payload size (i.e. number of bits in the control information).

(1) Different scrambling sequence

As an optional embodiment, because the control information is DCI common to the terminal group, when all the terminal devices in the terminal group delay sending the uplink data on the first time domain resource unit, the network device only needs to send the DCI common to the terminal group to the terminal devices, and can trigger the terminal devices to send the uplink data delayed from the first time domain resource unit on the second time domain resource unit, so that signaling overhead can be reduced.

(2) The mapped resources are different

(3) Payload size difference

The control information is used to indicate the first time domain resource unit and the second time domain resource unit.

Optionally, as shown in fig. 7, the control information may include 2 fields, where the 1 st field carries an identifier of a delayed time domain resource unit, and the 2 nd field carries an identifier of a time domain resource unit used after triggering.

For example, when the first time domain resource unit is timeslot 2, and the second time domain resource unit is timeslot 5, the 1 st field of the control information carries the identifier of timeslot 2, and the 2 nd field carries the identifier of timeslot 5.

Optionally, as shown in fig. 8, the control information may include 2 fields, where the 1 st field carries an identifier of the delayed time domain resource unit, and the 2 nd field carries a time domain resource unit offset value k, that is, the number of time domain resource units between the time domain resource unit used after the triggering and the delayed time domain resource unit.

For example, when the first time domain resource unit is timeslot 2 and the time domain resource unit offset value k is 2, the 1 st field of the control information carries the identifier of timeslot 2, and the 2 nd field carries k ═ 2.

Optionally, when the network device determines that there are multiple delayed time domain resource units, the control information may trigger the multiple delayed time domain resource units, where the multiple delayed time domain resource units include the first time domain resource unit, which is not limited in this embodiment of the present application.

As an optional embodiment, when the network device determines that the uplink data in the first time domain resource unit and the uplink data in the third time domain resource unit are both sent with a delay, the network device may trigger, through the control information, sending the data sent with a delay in the first time domain resource unit in the second time domain resource unit, and sending the data sent with a delay in the third time domain resource unit in the fourth time domain resource unit.

Optionally, as shown in fig. 9, the network device may number the multiple delayed time domain resource units in a time sequence, where the control information may include multiple pieces of sub-control information, the multiple pieces of sub-control information correspond to the multiple delayed time domain resource units one to one, the sub-control information includes 2 fields, a 1 st field carries an identifier of a delayed time domain resource unit, and a 2 nd field carries an identifier of a time domain resource unit used after triggering corresponding to the delayed time domain resource unit.

For example, when the first time domain resource unit is timeslot 2, the second time domain resource unit is timeslot 5, the third time domain resource unit is timeslot 3, and the fourth time domain resource unit is timeslot 6, the 1 st field of the control information carries the identifier of timeslot 2, the 2 nd field carries the identifier of timeslot 5, the 3 rd field carries the identifier of timeslot 3, and the 4 th field carries the identifier of timeslot 6.

Optionally, as shown in fig. 10, the network device may number the plurality of delayed time domain resource units in a time sequence, where the control information may include a plurality of pieces of sub-control information, the plurality of pieces of sub-control information correspond to the plurality of delayed time domain resource units one to one, the sub-control information includes 2 fields, a 1 st field carries an identifier of a delayed time domain resource unit, and a 2 nd field carries a time domain resource offset value k corresponding to the delayed time domain resource unit.

For example, when the first time domain resource unit is timeslot 2, the second time domain resource unit is timeslot 5, the third time domain resource unit is timeslot 3, and the fourth time domain resource unit is timeslot 6, the 1 st field of the control information carries the identifier of timeslot 2, and the 2 nd field carries k ₁2, the 3 rd field carries the identification of this slot 3, the 4 th field carries k₂＝2。

Optionally, the terminal device that delays sending of the uplink data in the first time domain resource unit and the terminal device that delays sending of the uplink data in the third time domain resource unit may be the same terminal device or may be different terminal devices in the same terminal group, which is not limited in this embodiment of the present application.

It should be understood that, the method for the network device to trigger the data delayed for transmission on the third time domain resource unit by the control information is similar to the method for the network device to trigger the data delayed for transmission on the first time domain resource unit by the control information on the second time domain resource unit, and is not repeated here to avoid repetition.

And S250, the terminal equipment determines a target time domain resource unit according to the control information.

S260, the network device determines a target time domain resource unit according to the control information.

It should be understood that S260 is similar to S250 and will not be described here to avoid repetition.

S270, the terminal device sends the first data to the network device on the target time domain resource unit; accordingly, the network device receives the first data sent by the terminal device on the target time domain resource unit.

It should be understood that the network device only needs to indicate the time domain resource unit (target time domain resource unit) used after the triggering by the control information, and does not need to indicate the uplink time domain resource used by the terminal device in the target time domain resource unit, that is, the terminal device sends the first data on the target time domain resource unit by using the uplink time domain resource that is the same as the uplink time domain resource used on the first time domain resource unit.

For example, as shown in fig. 11, the network device instructs the terminal device to transmit the first data on symbol 4 and symbol 5 in slot 1 through the first scheduling information, and the control information triggers the terminal device to transmit the data delayed to be transmitted on slot 1 on slot 3, and the terminal device transmits the first data on symbol 4 and symbol 5 in slot 3.

Optionally, other information used by the terminal device to transmit the first data on the target time domain resource unit may be the same as other information used on the first time domain resource unit.

Optionally, the other information may include at least one of information used for scheduling the terminal device, such as an uplink frequency domain resource, an uplink code domain resource, a coding mode, a transmission power and frequency hopping sequence, and a resource mapping mode, which is not limited in this embodiment of the present application

That is to say, the network device only needs to indicate the time domain resource unit (target time domain resource unit) used after the triggering by the control information, and does not need to indicate any information of the uplink frequency domain resource, the coding mode, the transmission power and the frequency hopping sequence, the resource mapping mode, and the like used by the terminal device in the target time domain resource unit. That is, the uplink frequency domain resource, the coding mode, the transmitting power and the frequency hopping sequence, the resource mapping mode, etc. adopted by the terminal device on the target time domain resource unit are the same as those of the first time domain resource unit.

Optionally, since the control information is a common DCI of a terminal group, each terminal device in the terminal group may receive the control information, but in some scenarios, the control information is not applicable to individual terminal devices. At which point the network device may reschedule the terminal device.

For example, the control information triggers sending of the data delayed in the first time domain resource unit on the second time domain resource unit, and the uplink frequency domain resource used by the terminal device in the second time domain resource unit is occupied by other terminal devices.

As an optional embodiment, the network device may send second scheduling information to the terminal device, where the second scheduling information is used to instruct the terminal device to send the first data on an uplink time domain resource in a third time domain resource unit, and the terminal device sets the third time domain resource unit indicated by the second scheduling information as the target time domain resource unit according to that the priority of the second scheduling information is higher than that of the control information.

It should be understood that the second scheduling information is also used to indicate at least one of information used for scheduling the terminal device, such as uplink frequency domain resources, coding schemes, transmission power and frequency hopping sequences, resource mapping schemes, and the like used by the terminal device to transmit the first data on the first time domain resource unit, which is not limited in this embodiment of the present application.

It should also be understood that the second scheduling information is different from at least one of the following of the control information: scrambling sequence, mapped resources and payload size. The specific difference between the second scheduling information and the control information is similar to the difference between the first scheduling information and the control information, and is not repeated here to avoid repetition.
