In this example, above-mentioned steps 401 can specifically include:

Step 401a, network side equipment determine the configuration information according to the second indication information.

I.e. network side equipment can be according to second indication information, the type for a variety of physical characteristics supported from the terminal device In, determine at least two physical characteristic corresponding at least one the first HARQ unit of the terminal device is allocated to.It is more from this The switching condition between at least two physical characteristic is determined in switching condition between kind physical characteristic.And from a variety of objects Manage the switching time determined between at least two physical characteristic in the switching time between characteristic.

It is understood that passing through method described in the example, it is ensured that the configuration information that network side equipment determines It is available for the terminal device, avoids the configuration information that the terminal device does not support network side equipment to determine.

Referring to Fig. 5, it is a kind of flow chart of another embodiment of data transmission method provided by the present application, specifically describes Terminal device transmits the implementation method of the data of N (as N > 1) kind business, i.e. above-mentioned steps 403 according to the configuration information A kind of optional implementation, this method may include:

Step 501, network side equipment receives the uplink authorization information that network side equipment is sent to terminal device, which awards Power information is used to indicate the second radio resource, HARQ serial number and the first sender that terminal device sends the data of the first business Formula, first business are one of N kind business business.

Illustratively, when terminal device detects that the data of the first business reach the buffer area of the terminal device, the end End equipment can be according to the business demands of the data of the first business (for example, the data volume of the data of the first business and to transmission The requirement etc. of mode) generate buffer status report (Buffer Status Report, BSR).Then the BSR is sent to network Side apparatus, so that network side equipment determines the radio resource for sending the data of the first business for terminal device according to the BSR (i.e. the second radio resource), the HARQ serial number and sending method (i.e. the first sending method) used.Network side equipment passes through upper Row authorization message indicates second radio resource, the HARQ serial number and first sending method.

In this application, the first sending method may include the configuration mode of the first HARQ unit and/or second wireless The physical characteristic of resource.

Step 502, which determines that the data of the second business reach the buffer area of the terminal device, and the terminal is set The priority of the standby radio resource that the data for sending second business have not been obtained, second business is higher than first business Priority, which is one of N kind business business.

Step 503, which seizes second radio resource work according to the business demand of the data of second business For send second business data radio resource, and determination it is corresponding with the radio resource being preempted in second radio resource The second sending method.

Wherein, the second sending method may include the configuration mode and/or second radio resource of the first HARQ unit In the physical characteristic of radio resource that is preempted.

In this application, it when terminal device needs to send the data of the second business, but also has not been obtained for sending this When the radio resource of the data of the second business, which can seize the second radio resource got and (be used for Send radio resource of the priority level lower than the data of the first business of the second business), and change in second radio resource The sending method for the radio resource being preempted is changed the sending method of the radio resource being preempted from the first sending method For the second sending method.

It should be noted that in this application, can be the change of the first sending method in the first sending method Partial parameters are modified, and all parameters being also possible in the first sending method are modified.It is understood that when first When sending method can satisfy the business demand of the data of the second business, the first sending method can not also be changed, directly by One sending method is determined as the second sending method.

Fixed mode can be used to seizing for Secondary resource.For example, needing when terminal device determines to the nothing obtained When line resource is seized, which can seize the 2nd symbol in the radio resource to according to the fixed mode 4 symbols send the data of the second business.Alternatively, terminal device can also be according to the business demand pair of the data of the second business Second radio resource is seized at random.For example, the part radio resource seized in second radio resource at random sends The data of two business.

Step 504, the terminal device is according to second sending method, the first HARQ unit indicated by the HARQ serial number Control, the data of second business are sent to the network side equipment on the radio resource being preempted.

In this application, when terminal device needs to send the data of the second business of burst, terminal device is without request Network side equipment distributes new HARQ unit, is directly multiplexed the first HARQ unit of the HARQ serial number instruction got, with The transmission of the data of the second business is controlled by the first HARQ unit.And terminal device can also be according to the data of the second business Business demand, modify to the sending method for the radio resource being preempted, will be originally used for send the first business data First sending method is revised as the second sending method, to meet the business demand of the data of the second business.To avoid the occurrence of by It is obtained not in time in the transfer resource of the data of the second business, and leads to not the demand for meeting the business of the data of the second business The problem of.

Step 505, which obtains the terminal from the radio resource being preempted in second radio resource and sets The data for the second business that preparation is sent.

In this application, network side equipment can determine that in several ways the second radio resource is preempted, and obtaining should The second data transmitted on the radio resource being preempted.Below by taking two ways once as an example, illustratively illustrated.

Mode one, network side equipment can detect the data transmitted on the second radio resource by way of blind examination.Example Property, network side equipment is using corresponding first sending method of known and the first business and the second hair corresponding with the second business Mode is sent, successively the data transmitted on second radio resource are decoded.If which kind of sending method successfully decoded, network The data that side apparatus can confirmly detect are the data of that business.

Mode two, terminal device can also notify the network side equipment terminal device to seize feelings to second radio resource Condition, so that network side equipment seizes situation according to this.For example, terminal device can be after above-mentioned steps 503, step 504 Before, the first instruction information is sent to the network side equipment, which includes preemption information and/or second transmission Mode.The preemption information is used to indicate the radio resource being preempted.So after receiving end receives the first instruction information, The number for the second business that terminal device is sent can be obtained on the radio resource being preempted from this according to the first instruction information According to.

It should be noted that the first instruction information can be sent before sending the second data；It can also carry second In the data packet of business datum, the data with the second business are sent together；It can also be sent immediately after sending the second data.

Illustratively, which is that the terminal device sends the demodulation reference letter used when the data of second business The first circulation of number (Demodulation Reference Signal, DMRS) shifts (cyclic shift, CS), this first What sending for the terminal device of indicating in cyclic shift and the uplink authorization information used when the data of first business The second circulation of DMRS shifts different.

For example, it is assumed that the CS=6 of the DMRS indicated in the uplink authorization information of network side equipment distribution (move by first circulation Position).And CS ≠ 6 (for example, second circulation shifts CS=5) that network side equipment detects on the second radio resource.So net Network side apparatus can determine that the second radio resource is preempted.

Alternatively, the preemption information is the first difference of first circulation displacement with second circulation displacement, it can be by the One difference indicates the character position of the radio resource being preempted in the second radio resource.For example, it is assumed that second circulation displacement is 6.If seizing first sign-on every time from the second radio resource, then when network side equipment is in the second wireless money When detecting that first circulation displacement is 4 on source, since first circulation displacement is different from second circulation displacement, network side is set It is standby to determine that the second radio resource is preempted.And since the first difference is 2 (6-4=2), network side equipment can be true The first two symbol in fixed second radio resource is preempted.

Alternatively, the preemption information be the first circulation displacement with the second circulation displacement where guard interval the upper bound or Second difference of lower bound can indicate the sign bit for the radio resource being preempted in the second radio resource by the first difference It sets.For example, it is assumed that second circulation displacement is 6, first circulation displacement is 3, and the parameter of guard interval length is 2, i.e. second circulation It is 8 that guard interval where displacement, which is the upper bound [6-2,6+2], lower bound 4.So, it is moved due to first circulation displacement with second circulation Position is different, and therefore, network side equipment can determine that the second radio resource is preempted.And work as the difference that the second difference is 4 and 3 (i.e. 1) when, network side equipment can determine that preceding 1 symbol in the second radio resource is preempted；When the difference that the second difference is 8 and 3 When (i.e. 5), network side equipment can determine that preceding 5 symbols in the second radio resource are preempted.

Optionally, which also may include the frequency domain position information of the radio resource being preempted, this is preempted The time-domain position information of radio resource, the airspace location information of the radio resource being preempted, the radio resource being preempted RB location information and at least one of the symbol numbers of radio resource being preempted information.Wherein, frequency domain position is believed Breath may include the position Physical Resource Block (physical resource block, PRB), PRB number, t easet ofasubcarriers position It sets and at least one of the number of t easet ofasubcarriers information；Time-domain position information may include time slot (slot) position, At least one of the number of the number of time slot, the position of minimum time slot (mini-slot) and minimum time slot information；Airspace position Confidence breath may include the number of the scheduling unit position in airspace, the number of scheduling unit in airspace, the serial number of wave beam and wave beam At least one of mesh information.

In one example, the first instruction information can be an index information, which seizes for mapping this Information and/or second sending method.Index information and preemption information can be pre-saved in network side equipment and terminal device And/or mapping relations (mapping relations, index information and hair i.e. between index information and preemption information between sending method Send the mapping relations between the mapping relations or index information and preemption information and sending method between mode).To when eventually End equipment seizes the second radio resource of the data for sending the first business, and changes the radio resource being preempted When sending method, there can be the index information of mapping relations according to situation and/or the selection of the second sending method is seized, as the One instruction information is sent to network side equipment.

Illustratively, it is assumed that subframe (1ms) is second radio resource, include in the time domain two time slots (when Gap 0 and time slot 1), each time slot includes symbol 0-6.It include subcarrier 0-11 on frequency domain.As shown in Figure 6A, terminal device root Symbol according to the business demand of the data of the second business, after being seized to the second radio resource, in the second radio resource in time slot 0 The data of the first business are transmitted on symbol 1-2 and 4-6 in number 0-2 and 4-5 and time slot 1, the symbol 3 in time slot 0 uploads Defeated DMRS corresponding with the data of the first business.Second is transmitted on the symbol 0 in the symbol 6 and time slot 1 in time slot 0 being preempted The data of business transmit the second sending method on the symbol 3 in time slot 1 being preempted.

As shown in Figure 6B, terminal device robs the second radio resource according to the business demand of the data of the second business After accounting for, first is transmitted on the symbol 1-2 and 4-6 in the symbol 0-2 and 4-5 and time slot 1 in the second radio resource in time slot 0 The data of business, transmission DMRS corresponding with the data of the first business on the symbol 3 in time slot 0 and time slot 1.The time slot being preempted The second sending method is transmitted on symbol 6 in 0, the data of the second business are transmitted on the symbol 0 in time slot 1 being preempted.

As shown in Figure 6 C, terminal device robs the second radio resource according to the business demand of the data of the second business After accounting for, on the symbol 1 and subcarrier 0-2 on the symbol 0-2 and 4-5 in the second radio resource in time slot 0, in time slot 1, The data of the first business are transmitted on 2 and 4-6 in time slot 1.It is transmitted on symbol 3 in time slot 0 and time slot 1 and the first business The corresponding DMRS of data.On the symbol 6 and subcarrier 0-2 in time slot 0 being preempted, the symbol 0 in time slot 1 and son carry The data of the second business are transmitted on symbol 1 and subcarrier 3-11 on wave 0-11, in time slot 1.The symbol in time slot 0 being preempted The second sending method is transmitted on number 6 and subcarrier 3-7.The symbol 6 in time slot 0 and subcarrier 8-11 being preempted upload Defeated preemption information.
