Related access network equipment can be used for providing wireless communication function for terminal device in embodiments of the present invention.The access network equipment may include various forms of macro access network equipments, micro- access network equipment (also referred to as small station), relay station, access point etc..The access network equipment can be access network equipment (the Base T access net sceiver Station in GSM or CDMA, BTS), access network equipment (the NodeB being also possible in WCDMA, NB), it can also be evolved access network equipment (the Evolutional Node B in LTE, eNB or e-NodeB), and can be corresponding equipment gNB in 5G network.For convenience of description, in all embodiments of the invention, the above-mentioned device for providing wireless communication function for terminal device is referred to as access network equipment.

In embodiments of the present invention, the terminal device is also referred to as user equipment (User Equipment, UE), mobile station (Mobile Station, MS), mobile terminal (Mobile Terminal) etc., the terminal device can be through wireless access network (Radio Access Network, RAN it) is communicated with one or more core net, such as, terminal device can be mobile phone (or being " honeycomb " phone), computer etc. with mobile terminal, such as, terminal device can also be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they exchange language and/or data with wireless access network.It is not specifically limited in the embodiment of the present invention.

The embodiment of the present invention can be applied to using exempting from the system that licensed spectrum is communicated.

In order to realize on exempting from licensed spectrum and Wireless Fidelity (WirelessFidelity,) etc. Wi-Fi the close friend of systems coexists, terminal device uses first to listen when sending signal sends out (Listen-Before-Talk afterwards, LBT) Channel Access Mechanism, communication channel is evaluated and tested using idle channel evaluation and test (Clear Channel Assessment, CCA).Only evaluation result is channel idle, and UE just can be used this and exempt from licensed spectrum On channel send data.Equipment by channel idle evaluation and test to be allowed to occupy exempt from licensed spectrum send data after, occupancy exempt from licensed spectrum transmission data.But it occupies and exempts from licensed spectrum to send the time span of data to be limited.Equipment, which is allowed to occupy, to be exempted from licensed spectrum to send the time span of data to be that maximum channel occupies duration MCOT (Maximum Channel Occupancy Time).

Wireless telecom equipment can be divided into two types exempting from licensed spectrum and execute idle channel evaluation and test: the first evaluation and test type: equipment listens to channel first and determines channel in a timing period (defer duration) T_fIt is idle state in the time of=16us, the CCA that then equipment executes a single time slot is listened to, the CCA time of intercept section T of the list time slot_sl, wherein T_sl=9 μ s.If equipment is in T_slTime in still detect channel idle, then equipment can send data on this channel.Second evaluation and test type: equipment arrives CW 0_pBetween randomly choose a random number N=N_initInitial value is counted as random back.Equipment listens to channel first and determines channel in a timing period (defer duration) T_dIt is idle state in time, wherein T_d=T_f+m_p*T_sl,16us≤T_f≤16us+T_s, 9us≤T_sl≤9us+T_s, T_sFor the time interval of double sampling.m_pThe corresponding numerical value of the priority type of data to be sent with equipment.Then the CCA that equipment successively executes single time slot one by one is listened to, and the CCA time of intercept section of single time slot is T_sl, wherein T_sl=9 μ s.If the result that equipment evaluates and tests channel in single time slot CCA time of intercept is channel idle, above-mentioned random back count value is subtracted 1；If the result that equipment evaluates and tests channel in single time slot CCA time of intercept is that channel is busy, above-mentioned random back count value N is constant.When random back count value is kept to 0, equipment can determine that final channel evaluation result is channel idle, then equipment can send data on this channel.When equipment executes the evaluation and test of channel idle channel with the first evaluation and test type, channel test process is shorter, and when the result for evaluating and testing channel is channel idle, the time for being allowed to busy channel is shorter.When equipment executes the evaluation and test of channel idle channel with the second evaluation and test type, channel test process is longer, and when the result for evaluating and testing channel is channel idle, the time for being allowed to busy channel is longer.

Fig. 1 is the schematic flow chart of ascending transmission method 100 according to an embodiment of the present invention.As shown in Figure 1, method 100 may include following content.

110, access network equipment sends control information to terminal device, controlling information includes the first instruction information and second indication information, first instruction information is used to indicate terminal device and sends SRS and be used for transmission relative position of the first subframe of SRS in sub-frame set, second indication information is used to indicate terminal device at least one short transmission time interval (Short Transmission Time Interval, STTI) STTI in set sends uplink information, which includes the subframe where at least one STTI in STTI set.

It may include one or more STTI in STTI set.At least one STTI in STTI set The subframe at place can be one or more subframes, i.e. the sub-frame set may include one or more subframes.

Control information can carry in the Downlink Control Information DCI (Downlink Control Information) of uplink scheduling authorization (UL grant).The control information sends uplink information in a STTI for dispatch terminal equipment, or sends uplink information in more than one STTI for dispatch terminal equipment.That is, STTI of the control message scheduling terminal device in STTI set sends uplink information, wherein STTI set includes one or more STTI.Uplink information may include the upstream data and/or ascending control information sent by PUSCH, wherein ascending control information can be hybrid automatic repeat-request (Hybrid Automatic Repeat reQuest, HARQ) at least one of response message HARQ-ACK and channel state information (CSI, Channel-State Information).Wherein, HARQ-ACK includes HARQ confirmation (Acknowledgement, ACK), HARQ non-acknowledgement (Negative Acknowledgement, NACK), HARQ discontinuously send (Discontinuous Transmission, DTX) etc..

Time span of the time span of STTI less than a subframe.Subframe can refer to the definition of existing protocol, can also be with reference to the definition in future protocol.For example, the time span of a subframe can be 1ms as defined in existing protocol, it is also possible to other times length as defined in future protocol.In some embodiments, the time span of a subframe is equal at least about the sum of the time span of two STTI.

For example, the time span of a subframe can be the time span of 14 symbols, the time span of a STTI can be the time span of 7 symbols, or may be the time span of 2,3 or 4 symbols, as shown in Fig. 2A, 2B, 2C and 2D.

In some embodiments, the time span of each STTI in STTI set is identical, that is to say, that the STTI in STTI set is same type of STTI.In further embodiments, the time span of the STTI in STTI set can be partially different, that is to say, that may include the STTI of at least two types in STTI set, wherein the time span of each type of STTI is different, as shown in Figure 3.

For example, including 6 STTI in a subframe, on the time from front to back, the symbol numbers of 6 STTI are 3,2,2,2,2,3 respectively；Alternatively, on the time from front to back, the symbol numbers of 6 STTI are 2,2,3,2,2,3 respectively；Alternatively, on the time from front to back, the symbol numbers of 6 STTI are 2,2,2,2,2,2 respectively.Again for example: including 4 STTI in a subframe, on the time from front to back, the symbol numbers of 4 STTI are 3,4,3,4 respectively；Alternatively, on the time from front to back, the symbol numbers of 4 STTI are 4,3,4,3 respectively；Alternatively, on the time from front to back, 4 The symbol numbers of STTI are 4,3,3,4 respectively；Alternatively, on the time from front to back, the symbol numbers of 4 STTI are 3,4,4,3 respectively.Again for example: including 2 STTI in a subframe, on the time from front to back, the symbol numbers of 2 STTI are 7,7 respectively.

Access network equipment can be as unit of a subframe granularity of the data dispatch of terminal device in time, be also possible to as unit of STTI.

The time range of one STTI is in a corresponding subframe, the subframe which can be known as where the STTI.For example, as shown in Figure 2 A, the symbol numbers in a subframe including STTI 1 and STTI 2, STTI 1 and STTI 2 are 7,7 respectively, and the subframe where subframe, that is, subframe n, STTI 2 where STTI 1 is also subframe n.The subframe where subframe and STTI2 in example shown in Fig. 2A where STTI 1 is same subframe.

120, after terminal device receives the control information that access network equipment is sent, SRS is sent in the first subframe according to the first instruction information, and uplink information is sent according to STTI of the second indication information in STTI set.

Access network equipment can in the first subframe receiving terminal apparatus send SRS, and STTI set in STTI on receiving terminal apparatus send uplink information.

First subframe can be sub-frame of uplink, be also possible to special subframe.Special subframe refers to not only can be used for uplink, but also can be used for the subframe of downlink transfer.

The STTI that terminal device can be indicated according to second indication information, which gathers, determines sub-frame set, and determines the first subframe according to relative position and the sub-frame set of the first subframe of the first instruction information instruction in sub-frame set.Terminal device can send SRS on the predetermined symbol of the first subframe according to the first instruction information as a result, which is the symbol for being used for transmission SRS of definition.

It should be noted that according to the LBT rule exempted from licensed spectrum and send information is occupied, if the first subframe is the subframe exempted from licensed spectrum, terminal device need to guarantee that the position for sending SRS is allowed to occupy this and exempt from licensed spectrum transmission information before sending SRS.Equally, if, if the STTI in above-mentioned STTI set is the STTI exempted from licensed spectrum, terminal device needs to guarantee that the position for sending the STTI in STTI set is allowed to occupy this and exempts from licensed spectrum and send information before the STTI in STTI set sends uplink information.If not being allowed to occupy this in the position for sending SRS and exempt from licensed spectrum sends information, terminal device do not send SRS in the first subframe.Equally, if be not allowed to for send STTI set in STTI position occupy this exempt from licensed spectrum send information, terminal device do not send STTI set in STTI.If be allowed to for send STTI set in part STTI position occupy this exempt from licensed spectrum send information, terminal device only send STTI set in these portions Divide STTI.

It should be understood that the predetermined symbol of a subframe can be used for transmitting SRS, transmission uplink information can be used for.When the subframe is as the subframe for being used for transmission SRS, SRS is used for transmission in the predetermined symbol of the subframe；When the subframe is not as the subframe for being used for transmission SRS, the predetermined symbol of the subframe is used for transmission information or the predetermined symbol of the subframe is not used in any information of transmission.

For example, the predetermined symbol of a subframe can be the last symbol of a subframe.

Access network equipment and terminal device can make an appointment predetermined symbol, or can also be pre-configured with predetermined symbol in access network equipment and terminal device.If it is determined that the subframe for sending SRS, then terminal device can send SRS on the predetermined symbol of the subframe.

In the prior art, access network equipment is that terminal device is pre-configured with the sub-frame set for sending SRS, and terminal device selects the subframe for sending SRS according to the subframe position for sending uplink information indicated in the control information received from the preconfigured sub-frame set.Since terminal device must select the subframe of transmission SRS from preconfigured sub-frame set, the scheduling of SRS is inflexible.

Therefore, the embodiment of the present invention passes through the relative position of the sub-frame set of the subframe composition where at least one STTI in the STTI set for sending uplink information indicated according to the control information, the subframe for being used for transmission SRS of control information instruction in sub-frame set and determines the subframe for sending SRS, enables to the scheduling of SRS more flexible.

Optionally, the sub-frame set can be gathered by STTI in STTI where subframe form or the sub-frame set can also be gathered by STTI in include predetermined symbol STTI where subframe form, wherein predetermined symbol be define the symbol for being used for transmission SRS.

Below with reference to two kinds of situations that Fig. 4 and STTI shown in fig. 5 gathers, both different sub-frame sets are described.

If the sub-frame set by STTI gather in STTI where subframe form, STTI shown in Fig. 4 set includes 1~STTI of STTI 6, and since the subframe where 1~STTI of STTI 6 is subframe n and subframe n+1, then the sub-frame set includes subframe n and subframe n+1；STTI set shown in fig. 5 includes 1~STTI of STTI 8, and since the subframe where 1~STTI of STTI 8 is subframe n and subframe n+1, then the sub-frame set includes subframe n and subframe n+1.Since SRS is that predetermined symbol in a subframe is sent, therefore by sub-frame set be defined as being gathered by STTI in STTI subframe form, subframe where enabling to any STTI in STTI set may be incorporated for sending SRS, so that the scheduling of SRS is more flexible.

If the sub-frame set by STTI gather in include predetermined symbol STTI where subframe form, Assuming that the last symbol of subframe is predetermined symbol, in 1~STTI of STTI set TTI shown in Fig. 46, only STTI 3 includes predetermined symbol, then the sub-frame set includes the subframe n at 3 place STTI；For in 1~STTI of STTI set STTI shown in fig. 58, STTI 4 and STTI 8 include predetermined symbol, then the sub-frame set includes the subframe n+1 at 8 place subframe n and STTI where STTI 4.If being spaced at least one symbol between the predetermined symbol and the last one STTI of subframe where the last one STTI in STTI set, since SRS is that predetermined symbol in a subframe is sent, if the subframe where the last one STTI is confirmed as the first subframe, then terminal device can will exempt from channel release a period of time of licensed spectrum after the STTI in STTI set sends uplink information.Terminal device needs to carry out idle channel evaluation and test before sending SRS, if air passage of the terminal device before sending SRS evaluates and tests failure, will lead to SRS and sends failure.In the embodiment of the present invention, by including that the subframe where the STTI of predetermined symbol forms in being defined as being gathered by STTI by sub-frame set, subframe where at least one STTI can be excluded from sub-frame set, this means that SRS by cannot the predetermined symbol of subframe where at least one STTI again send, therefore it can be avoided SRS caused by idle channel evaluation and test failure of the terminal before sending SRS and send failure, so as to improve the emission effciency of SRS.For example, the STTI in STTI set is 6 times upper adjacent STTI shown in Fig. 4, which does not include the predetermined symbol of the subframe n+1 where STTI4, STTI5 and STTI6 therein common.If sub-frame set by STTI gather in include predetermined symbol STTI where subframe form, i.e. sub-frame set includes subframe n, control information only can instruction terminal equipment subframe n predetermined symbol send SRS, without instruction terminal equipment subframe n+1 predetermined symbol send SRS.

In some embodiments, the first instruction information can directly indicate relative position of first subframe in sub-frame set.First instruction information can be X bit (bit),Wherein Y be used for transmission indicated by above-mentioned control information uplink information STTI set in the corresponding sub-frame set of STTI included by number of sub-frames maximum value.WhereinExpression rounds up.

For example, Y=3, the first instruction information is 2 bits (bit).It is adapted to number, the position of the STTI in various STTI set indicated by above-mentioned control information, the number for the subframe for including in sub-frame set does not exceed 3.In as exemplified above, if the sub-frame set by STTI gather in include predetermined symbol STTI where subframe form, for STTI shown in Fig. 4 gather, above-mentioned sub-frame set includes subframe n, STTI shown in fig. 5 is gathered, above-mentioned sub-frame set includes subframe n and subframe n+1.But be still directed to Fig. 5 if the control information that access network equipment is sent either is directed to Fig. 4 and all use identical control information format, being used to indicate the instruction information of relative position of the first subframe for being used for transmission SRS in sub-frame set included by the first instruction information therein is 2bit.Then the first instruction information It is as shown in table 1 below with the corresponding relationship of relative position of first subframe in sub-frame set.For example, there is 4 subframes in sub-frame set, then the first instruction information can be indicated with 2bit, as shown in table 1 below.

Table 1

First instruction information	Relative position of first subframe in sub-frame set
00	First subframe is first subframe in sub-frame set
01	First subframe is second subframe in sub-frame set
10	First subframe is the third subframe in sub-frame set
