After the network equipment determines the first instruction information, the first instruction information is sent to terminal device.

In a kind of possible implementation, the running time-frequency resource of reference can be uplink reference resources (reference Uplink resource, RUR), then the running time-frequency resource for stopping the transmission of current upstream data can be in uplink reference resources First resource.The first instruction information can also be used for indicating that the first resource in the uplink reference resources is occupied, Huo Zhesuo State the instruction of the first instruction information is the opposite time-frequency location of first resource.The time domain scale of the uplink reference resources includes spirit Symbol living and/or uplink symbol.

Specifically, available the first instruction information sent from the network equipment of terminal device.Here, the first instruction letter Breath can seize instruction (uplink preemption indication, UL PI) for uplink, and UL PI can serve to indicate that this Terminal device stops the transmission of upstream data on which running time-frequency resource.UL PI can be hereinafter known as uplink seize it is logical Know or PI.In addition, the running time-frequency resource set of carrying UL PI can occupy one or more symbols in the time domain.

Specifically, the first instruction information can by the uplink reference resources or with reference to time-domain position indicate the first money Source.In one possible implementation, when ascending resource is uplink reference resources RUR, UL PI can serve to indicate that RUR Middle first resource is preempted.In alternatively possible implementation, when ascending resource is uplink time-domain resource, UL PI can To be used to indicate the time-domain position of first resource in the uplink time-domain resource being preempted, terminal device is indicated by the UL PI Stop transmission upstream data on time-domain position.In alternatively possible implementation, UL PI is mainly used for instruction at first Between point stop transmission upstream data, terminal device first time point indicated by UL PI stop transmission upstream data.It needs It is bright, it is herein for example, the embodiment of the present application is not limited to this.

Here, the resource that first resource can occupy for URLLC business, such as the data and this URLLC number of scheduling of URLLC According to the resource that occupies of DCI, the resource that the data and corresponding DCI for being also possible to multiple URLLC occupy.It is understood that the One resource is also possible to URLLC occupancy, and the resource being overlapped with the scheduled ascending resource of some or certain eMBB business, Further, since the instruction granularity of PI may be relatively thick, therefore may not occupied by URLLC comprising a part in the resource of PI instruction Resource, the embodiment of the present application carried out to how to select resource instruction be not particularly limited.The terminal of transmission eMBB business is set After receiving PI, it is only necessary to be determined according to the instruction of PI and oneself need to stop sending upstream data in which resource. It can also be only frequency domain or time-domain information in addition, can be specific Time-Frequency Information when notifying first resource.

In the embodiment of the present application, if do not illustrated, by the running time-frequency resource of reference be uplink reference resources for into Row explanation.It is understood that method is equally applicable if ascending resource is uplink time-domain resource.Alternatively, if first refers to When showing that information only notifies the time for needing to stop sending, the side that the initial position of the time domain scale of uplink reference resources determines is determined Method is applied equally to determine the reference time-domain position that notice stops the time point sending, alternatively, determining uplink reference resources The method that the initial position of time domain scale and end position determine is applied equally to determine the starting for stopping the time point sending The reference time-domain position of the end position at the time point that position and stopping are sent.

Optionally, in the embodiment of the present application, the first instruction information is used to indicate the first money in uplink reference resources Source is occupied, and the time domain scale of the uplink reference resources includes flexible (flexible symbols) symbol and/or uplink symbol Number.

It should be understood that may include here one or more time domain units in the time domain scale of resource occupation, time domain unit can It also may include one or more time slots (slot) to include one or more time-domain symbols (symbol), can also include one A or multiple mini time slots (mini-slot), alternatively, including one or more subframes (subframe).Wherein, above-mentioned time domain symbol Number it can be orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol, It can be single carrier frequency division multiplexing (single-carrier frequency-division multiplexing, SC-FDM) symbol Number.It should be understood that time domain scale could alternatively be temporal interval or time-domain position, also, time domain unit in the embodiment of the present application It can be replaced time quantum.It will be hereafter described so that time domain unit includes one or more time-domain symbols as an example, but the application Embodiment is not limited to this.

Specifically, 5G system supports flexible structure of time slot, i.e., it can be completely used for uplink or downlink in 1 time slot, or Some symbols are used for uplink, some symbols are used for downlink.In some concrete implementation modes, the public physical down of group can be used Control channel (Group Common PDCCH) indicates that structure of time slot, structure of time slot also are understood as time slot format (Slot ) or time slot format relevant information (Slot format related information) Format.The network equipment sends Group Common PDCCH, it is uplink symbol that terminal device, which detects Group Common PDCCH and which symbol in slot obtained, which A little symbols are downlink symbols, which symbol is flexible symbol (flexible symbols).Alternatively, terminal device can also be passed through The configuration of dedicated (specific) Downlink Control Information DCI announcement slot format.Wherein, flexible symbol can according to configuration or Person scheduling for uplink perhaps downlink transfer for example, flexibly symbol can according to configuration or scheduling be changed to uplink symbol Or downlink symbol.

As described above, the type of a symbol can be one of DL, UL, flexible, time slot lattice in a slot Formula may include the various possible combinations that symbol is DL, UL, flexible.Fig. 3 is the example of a time slot format, and D is represented Downlink symbol, X represent flexible symbol, and U represents uplink symbol.Specifically, the part D includes at least one downlink symbol, the portion X Dividing includes at least one flexible symbol, and the part U includes at least one uplink symbol.

Optionally, in the embodiment of the present application, the network equipment or terminal device can be according to where the first instruction information Time-domain position determines the time domain scales of uplink reference resources, here the time domain scale of uplink reference resources include initial position and End position.

Specifically, seizing notice due to uplink is for notifying the terminal device being preempted to stop at by other terminal devices Upstream data is sent in the resource of occupancy, to avoid the terminal device and other terminal devices in the same time, use is identical Running time-frequency resource gives the network equipment to send upstream data, causes serious interference to the network equipment, thus uplink reference resources when Domain range should be after the time-domain position where the first instruction information.

Specifically, the network equipment can first determine the time-domain position for sending PI, RUR is then determined according to the time-domain position of PI Time domain scale.Alternatively, the network equipment can first determine the time domain scale of RUR, then determine the time-domain position for sending PI.Then, The network equipment can determine the particular content of PI, that is, determine the RUR according to the time-domain position RUR corresponding with the PI for determining PI In which resource will be occupied.

Also, terminal device can be determined when receiving the PI of network equipment transmission based on the mode of pre-configuration RUR.Specifically, terminal device can determine the corresponding RUR of the PI according to the time-domain position of PI.Further according to the specific of PI Content determines which resource in the RUR will be occupied.

In one possible implementation, the time-domain position of information can be indicated according to transmission first to determine that uplink is joined Examine the initial position of the time domain scale of resource.Here, the time-domain position of the first instruction information indicates carrying the first instruction information The time domain scale that resource collection occupies.If the first instruction information occupies 1 symbol, the time-domain position of the first instruction information is should The position of symbol in the time domain is occupied, if the first instruction information occupies multiple symbols, the first instruction information occupies in the time domain Multiple symbols, the time-domain position of the first instruction information is for the corresponding symbol in initial position to the corresponding symbol of end position in time domain On position.

Specifically, the network equipment can be by controlling resource collection (control resource set, CORESET) to end End equipment sends Downlink Control Information DCI, may include the PI in the DCI.CORESET is for sending Downlink Control Information A resource collection of DCI, is network equipments configuration to terminal device.Specifically, the network equipment can specify CORESET At least one of the DCI type of time-domain position, frequency domain position, time domain size, frequency domain size and carrying.In general, one CORESET may include 1-3 symbol.

As an example, can using carry PI time-domain position next symbol as the time domain model of uplink reference resources RUR The initial position enclosed.When determining the time domain scale of RUR using which, if under next symbol of the symbol of carrying PI is It when row symbol, is seized and is not occurred in downlink symbol due to uplink, in PI just corresponding to the indication bit of descender It wastes.

It, can be according to the type of the last symbol of the time-domain position where the first instruction information come really as another example Determine the initial position of RUR.Specifically, the last symbol of the time-domain position where the first instruction information can be uplink symbol Or flexible symbol.
