The present embodiments relate to terminal device, user can be directed to, the equipment of voice and/or data connectivity is provided, handheld device with wireless connecting function or other processing equipments for being connected to radio modem.Wireless terminal can be through wireless access network (Radio Access Network, RAN it) is communicated with one or more core net, wireless terminal can be mobile terminal, such as mobile phone (or be " honeycomb " phone) and the computer with mobile terminal, such as, can be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they exchange language and/or data with wireless access network.Such as, personal communication service (PCS, Personal Communication Service) phone, wireless phone, Session initiation Protocol (SIP) phone, wireless local loop (WLL, Wireless Local Loop) it stands, the equipment such as personal digital assistant (PDA, Personal Digital Assistant).Wireless terminal is referred to as system, subscriber unit (Subscriber Unit), subscriber station (Subscriber Station), movement station (Mobile Station), mobile station (Mobile), distant station (Remote Station), access point (Access Point), remote terminal (Remote Terminal), access terminal (Access Terminal), user terminal (User Terminal), user agent (User Agent), user equipment (User Device) or user equipment (User Equipment).

The network equipment involved in the embodiment of the present invention, can be base station, perhaps access point or can be refers to the accession in net equipment on interface in the sky by one or more sectors and wireless terminal communications.The air frame that base station can be used for receive mutually is converted with IP grouping, as the router between wireless terminal and the rest part of access net, wherein the rest part for accessing net may include Internet protocol (IP) network.Attribute management of the base station also tunable to air interface.Such as, base station can be the base station (BTS in GSM or CDMA, Base Transceiver Station), it is also possible to the base station (NodeB) in WCDMA, it can also be evolved base station (eNB or the e-NodeB in LTE, evolutional Node B), the application does not limit.

Uplink signal transmission method provided in an embodiment of the present invention sends the scene of uplink signal suitable for the terminal device under any wireless communication system in unlicensed spectrum.Wireless communication system mentioned here can be for example 2G communication system, 3G communication system, LTE communication system, 4G communication system, 5G communication system etc..

By taking the terminal device under LTE system sends uplink signal in unlicensed spectrum as an example, specifically:

The downstream transmission of LTE system is further realized in unlicensed spectrum completely on the basis of eLAA, downstream transmission is made to be no longer dependent on the auxiliary of authorization frequency spectrum by MulteFire standard.Simultaneously, in order to preferably utilize the channel resource of unlicensed spectrum, MulteFire is in addition to supporting terminal device to send extension Physical Uplink Control Channel (ePUCCH to base station in 1ms subframe, extended Physical Uplink Control Channel) except, when also supporting the symbol of terminal device used odd amount in addition to the round number frame when base station sends downlink transfer less than 10, short Physical Uplink Control Channel (sPUCCH, short Physical Uplink Control Channel) is sent to base station using last 4 symbols of the odd amount in addition to the round number frame.

Wherein, SRS can be carried in above-mentioned sPUCCH, Physical Random Access Channel (Physical Random Access Channel, referred to as: PRACH), scheduling request (Scheduling Request, referred to as: SR), hybrid automatic repeat-request confirms (Hybrid Automatic Repeat Request Acknowledge, referred to as: HARQ-ACK), one or more ascending control informations in channel state information (Channel State Information abbreviation: CSI) etc..When specific implementation, base station can send said one or multiple ascending control informations by CPDCCH configurating terminal device in sPUCCH.Wherein, base station can be notified by explicit CPDCCH control bit to terminal device, can also be by way of implicitly notifying, the odd amount in addition to the round number frame number of symbols for allowing terminal device to be indicated according to CPDCCH determines whether to send out Send HARQ-ACK.Since the CPDCCH control signaling for including all is the specific control signaling of cell, therefore, if configurating terminal device sends said one or multiple ascending control informations in CPDCCH, all terminal devices for receiving CPDCCH all can send said one or multiple ascending control informations according to the instruction of CPDCCH.

Wherein, PRACH, SR, HARQ-ACK, the one or more ascending control information such as CSI can be carried in above-mentioned ePUCCH.When specific implementation, base station can send said one or multiple ascending control informations by CPDCCH configurating terminal device in ePUCCH, can also send said one or multiple ascending control informations by uplink authorization UL grant instruction terminal equipment.

Due to all HARQ-ACK being supported to feed back in sPUCCH and ePUCCH, and ePUCCH can both be triggered by CPDCCH or be dispatched by uplink authorization UL grant, therefore, when base station may indicate that terminal device feeds back HARQ-ACK in sPUCCH, also indicate that terminal device feeds back HARQ-ACK in the ePUCCH in the same uplink, so that terminal may feed back HARQ-ACK in the sPUCCH and ePUCCH in a uplink, i.e., feed back HARQ-ACK twice in a relatively short period of time.Simultaneously, due in same uplink, the corresponding downstream data channel set of the HARQ-ACK fed back in ePUCCH includes the corresponding downstream data channel set of HARQ-ACK of sPUCCH feedback, therefore, how terminal device in the sPUCCH and ePUCCH in same uplink feeds back HARQ-ACK, the resource that uplink control channel could be efficiently used is a urgent problem to be solved.

Therefore, uplink signal transmission method provided in an embodiment of the present invention, in the case that terminal device is configured two up channels that can carry HARQ-ACK in same uplink, it can be used to indicate the third control information for sending other ascending control informations based on the received, on one of up channel of same uplink, abandons sending HARQ-ACK, but send other ascending control informations, to reach effective use channel resource, the purpose of the wasting of resources is avoided.

Number	First up channel	Second up channel
1	sPUCCH	ePUCCH
2	sPUCCH	PUSCH
3	First ePUCCH	2nd ePUCCH
4	ePUCCH	PUSCH

Wherein, above-mentioned first control information can be explicit control information, it can also be implicit control information, implicit control information mentioned here refers to that the not direct instruction terminal equipment of the first control information sends the first HARQ-ACK in the first up channel, but by indicating other correlation instruction contents, carrys out implicit instruction terminal equipment in the first up channel and send the first HARQ-ACK.When specific implementation, the first control information may include the control information carried in the control information and/or PDCCH notice signaling carried in high-rise RRC (Radio Resource Control) signaling.

By taking above-mentioned first up channel is sPUCCH as an example, then above-mentioned first control information can for example be divided into following five kinds of situations:

5th kind of situation: the first control information may include: the control information carried in CPDCCH, and, the entrained information instruction terminal equipment that specifically signals sends HARQ-ACK using which available resources in RRC signaling in available resource information at least one of (instruction frequency domain/code domain/airspace) that the network equipment carried in RRC signaling is multiple transmission HARQ-ACK of terminal equipment configuration, PDCCH, carrys out instruction terminal equipment in the first up channel and sends the first HARQ-ACK.That is, only RRC signaling indicates multiple available resources, and entrained specifically signaling in information indicates which available resources used in PDCCH, and, control information in CPDCCH also indicates that terminal device sends HARQ-ACK, and ability instruction terminal equipment sends the first HARQ-ACK in the first up channel.When specific implementation, the entrained information that specifically signals may include distribution resource instruction (the Acknowledgment Resource Indicator in DL grant in PDCCH, referred to as: ARI), it is used to indicate terminal device and sends HARQ-ACK using which available resources in RRC signaling.

For above-mentioned five kinds of situations, further, the first control information further include in PDCCH entrained being used to indicate signal information to terminal device allocation of downlink data resource, user receives this and signals information, the confirmation network equipment has sent downlink data, just sends the first HARQ-ACK.When specific implementation, above-mentioned user specifically signals information included in DL grant.

By taking above-mentioned first up channel is ePUCCH as an example, then above-mentioned first control information can for example be divided into following five kinds of situations:

The first situation: the marker that the first control information can specially indicate whether to be sent in the first HARQ-ACK of the first up channel transmission for one, so that the instruction terminal equipment that above-mentioned first control information can be shown sends the first HARQ-ACK in the first up channel.The marker can specifically signal information for cell entrained in PDCCH, when specific implementation, the marker for example can be 1 bit, when the bit is 1, instruction terminal equipment sends the first HARQ-ACK in the first up channel, or, when the bit is 0, instruction terminal equipment sends the first HARQ-ACK in the first up channel, specifically can be according to scene setting.Optionally, above-mentioned first control information can also specially indicate whether to be sent in the marker etc. that the first up channel sends the first HARQ-ACK for one carried in CPDCCH.

Second situation specifically may refer to above-mentioned first up channel be sPUCCH when, first control information second situation description, details are not described herein.

The third situation: the first control information includes that user entrained in PDCCH specifically signals an information in information, the specific signaling information of group etc..This, which specifically signals information, to send the first HARQ-ACK in the first up channel with instruction terminal equipment.Specifically, first control information includes the uplink authorization UL grant notice signaling carried in PDCCH, if the second up channel is the ePUCCH or PUSCH of UL grant instruction, terminal device can determine to be configured on the ascending resource of corresponding ePUCCH or PUSCH according to the signaling for including in UL grant sends HARQ-ACK.

4th kind of situation and the 5th kind of situation specifically may refer to above-mentioned first up channel be sPUCCH when, first control information the 4th kind of situation and the 5th kind of situation description, details are not described herein.

For above-mentioned five kinds of situations, further, first control information can also signal information to terminal device allocation of downlink data resource including entrained being used to indicate in PDCCH, user receives this and signals information, the confirmation network equipment has sent downlink data, just sends the first HARQ-ACK.When specific implementation, above-mentioned user specifically signals information included in DL grant.

The description as described in the second control information specifically may refer to state with above-mentioned first up channel when being ePUCCH, and to the specific descriptions of the first control information, details are not described herein.Optionally, if above-mentioned first up channel is ePUCCH, and above-mentioned first control information is the control information carried in CPDCCH, then above-mentioned second control channel can be for example control information of the carrying in UL grant.

Whether above-mentioned third control information is used to indicate terminal device in the first up channel the first uplink information of transmission.Wherein, above-mentioned first uplink information can specifically be determined according to the first up channel, such as: if above-mentioned first up channel is sPUCCH, above-mentioned first uplink information may include: one or more of SRS, PRACH, SR, CSI etc..If above-mentioned first up channel is ePUCCH, above-mentioned first uplink information may include: one or more of PRACH, SR, CSI etc..The description as described in third control information specifically may refer to state the specific descriptions of the first control information when the first up channel is sPUCCH, and details are not described herein.Wherein, above-mentioned third control information can carry in same signaling with the first control information, can also carry and be sent to terminal in different signalings, can specifically be determined according to actual use scene.

S102, terminal device receive the first control information, the second control information and third control information.

If S103, third, which control information instruction terminal equipment, sends the first uplink information in the first up channel, then terminal device controls information according to the second control information, third, determines and sends second to the first uplink information of network equipment transmission, on the second up channel to the network equipment on the first up channel HARQ-ACK。

Specifically, in the present embodiment, the corresponding downstream data channel set of above-mentioned 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK.Wherein, above-mentioned 2nd HARQ-ACK corresponds to second downstream data channel set and refers to, the 2nd HARQ-ACK includes the reception state for second downstream data channel set；In view of the HARQ-ACK of the second up channel carrying may include the reception state at least one downstream data channel, therefore second downstream data channel set includes at least one downstream data channel, the corresponding HARQ process of each downstream data channel, different downstream data channels correspond to different HARQ processes.First HARQ-ACK corresponds to first downstream data channel set and refers to, the first HARQ-ACK includes the reception state for first downstream data channel set；Similar, first downstream data channel set includes at least one downstream data channel, and each downstream data channel corresponds to a HARQ process, and different downstream data channels corresponds to different HARQ processes.In view of terminal device feedback HARQ-ACK is based on bit map (bitmap), i.e. reception state can be arranged for all HARQ processes in each HARQ-ACK in terminal device, but the first HARQ only corresponds to the downstream data channel within a time range, such as the closer time window downstream data channel of the first up channel of distance, and do not include the not downstream data channel within its correspondence time range；It is similar, the 2nd HARQ only closer downstream data channel of the second up channel of respective distances, and do not include and do not correspond to the downstream data channel within time range at it.

In view of the first up channel and the second up channel are likely located on the ascending resource being closer, therefore first downstream data channel set and second downstream data channel set may include the downstream data channel of overlapping, i.e. same downstream data channel may be both included in first downstream data channel set, be also contained in second downstream data channel set.In order to obtain the diversity gain that the network equipment receives HARQ-ACK, when same downstream data channel appears in first downstream data channel set and second downstream data channel set, and terminal device is when the first up channel and the second up channel all send HARQ-ACK (sending the first HARQ and the 2nd HARQ respectively), reception state in HARQ information for the downstream data channel is identical, even if the network equipment is lost one of up channel in this way, the HARQ-ACK information of the downstream data channel can also be obtained from the up channel that another is properly received.

The corresponding second downstream data channel set of 2nd HARQ-ACK includes that the corresponding first downstream data channel set of the first HARQ-ACK refers to that all data channels in first downstream data channel set appear in second downstream data channel set.In this case, if the network equipment can receive the 2nd HARQ, the available reception state to whole downstream data channels, without to receive first again HARQ；Therefore in this case, when receiving third control information and third control information instruction terminal equipment sends the first ascending control information, terminal device can abandon the first HARQ and send the first ascending control information terminal device.

Optionally, the reception state of data channel, which is positive, should indeed answer (Acknowledgement, ACK) or wrong responses (Negative Acknowledgement, NACK).Optionally, the reception state of data channel is ACK, NACK or discontinuous transmission (Discontinuous Transmission, DTX).For example, terminal device determines that a certain data channel reception is correct, then corresponding reception state is ACK；Alternatively, terminal device determines the data channel reception mistake, then reception state is NACK；Alternatively, terminal device determines that the data channel is not received by, then reception state is DTX；Alternatively, terminal device determines that the data channel is not received by, then reception state is NACK, that is to say, that is not received by by NACK designation date channel.

In this way, when above-mentioned third control information is used to indicate terminal device when the first up channel sends the first uplink information, then above-mentioned terminal device is according to the second control information, third controls information, determines and sends the first uplink information, in the 2nd HARQ-ACK of the second up channel transmission in the first up channel.That is, terminal device is abandoned sending the first HARQ-ACK on the first up channel, but send the first uplink information.Since the corresponding downstream data channel set of above-mentioned 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, in this way, terminal device can be made still to send the mode of the 2nd HARQ-ACK including the first HARQ-ACK to the network equipment, to make the network equipment still be able to learn the information of the first HARQ-ACK, simultaneously, the first uplink information can also be sent by the first up channel, increase the send opportunity of the first uplink information, achieve the purpose that efficiently use uplink control channel, improve the resource utilization of uplink.

It is SRS with the first uplink information, for above-mentioned first up channel is sPUCCH, in the prior art, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and SRS on sPUCCH, the 2nd HARQ-ACK is sent on sPUCCH by the second control information configuration terminal device.Since the priority of HARQ-ACK is high, so terminal device can be abandoned sending SRS but the first HARQ-ACK of transmission in sPUCCH, the 2nd HARQ-ACK is sent in the second up channel.At this time, since sPUCCH and the second up channel are the channel in same uplink, that is the corresponding downstream data channel set of the 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, this mode that the first HARQ-ACK is sent in sPUCCH in the prior art, will lead to the waste of the resource of uplink control channel.And the embodiment of the present invention Provided uplink signal transmission method, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and SRS on sPUCCH, the 2nd HARQ-ACK is sent on sPUCCH by the second control information configuration terminal device, then terminal device can send SRS in sPUCCH, and the first HARQ-ACK is abandoned, the 2nd HARQ-ACK is sent in the second up channel.Since the corresponding downstream data channel set of the 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, the network equipment can be while by receiving the 2nd HARQ-ACK to know a HARQ-ACK, SRS can also be received by sPUCCH, increase the send opportunity of SRS, channel detection is improved, has achieved the purpose that efficiently use uplink control channel, has improved the resource utilization of uplink.If above-mentioned uplink is the uplink of unlicensed spectrum, the utilization rate of unlicensed spectrum resource can be improved.

It is CSI/SR with the first uplink information, for above-mentioned first up channel is sPUCCH or ePUCCH, in the prior art, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and CSI/SR on the first up channel, the 2nd HARQ-ACK is sent on the first up channel by the second control information configuration terminal device.At this time, if the configuration of network equipment high-level signaling does not allow simultaneous transmission CSI/SR and HARQ-ACK, since the priority of HARQ-ACK is high, so terminal device can be abandoned sending CSI/SR but the first HARQ-ACK of transmission in the first up channel, the 2nd HARQ-ACK is sent in the second up channel.At this time, since the first up channel and the second up channel are the channel in same uplink, that is the corresponding downstream data channel set of the 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, this mode that the first HARQ-ACK is sent in the first up channel in the prior art, will lead to the waste of the resource of uplink control channel.And uplink signal transmission method provided by the embodiment of the present invention, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and CSI/SR on the first up channel, the 2nd HARQ-ACK is sent on the first up channel by the second control information configuration terminal device, then terminal device can send CSI/SR in the first up channel, and the first HARQ-ACK is abandoned, the 2nd HARQ-ACK is sent in the second up channel.Since the corresponding downstream data channel set of the 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, the network equipment can be while by receiving the 2nd HARQ-ACK to learn a HARQ-ACK, CSI/SR can also be received by the first up channel, increase the send opportunity of CSI/SR, achieve the purpose that efficiently use uplink control channel, has improved the resource utilization of uplink.If above-mentioned uplink is the uplink of unlicensed spectrum, unlicensed spectrum can be improved The utilization rate of resource.

It is CSI/SR with the first uplink information, for above-mentioned first up channel is sPUCCH or ePUCCH, in the prior art, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and CSI/SR on the first up channel, the 2nd HARQ-ACK is sent on the first up channel by the second control information configuration terminal device.At this point, so terminal device can will be sent on the first up channel after CSI/SR and the first HARQ-ACK combined coding, sending the 2nd HARQ-ACK in the second up channel if the configuration of network equipment high-level signaling allows simultaneous transmission CSI/SR and HARQ-ACK.At this time, since CSI/SR and the first HARQ-ACK are combined codings, two kinds of signals are sent out simultaneously has more bit numbers compared to only hair CSI/SR, code rate is caused to increase and decoding performance decline, therefore, this mode that CSI/SR and the first HARQ-ACK are sent in the first up channel in the prior art, while the probability of transmission failure for increasing CSI/SR and the first HARQ-ACK, the case where also resulting in because while sending the first HARQ-ACK and the 2nd HARQ-ACK, leading to the wasting of resources of uplink control channel.And uplink signal transmission method provided by the embodiment of the present invention, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and CSI/SR on the first up channel, the 2nd HARQ-ACK is sent on the first up channel by the second control information configuration terminal device, then terminal device can send CSI/SR in the first up channel, and the first HARQ-ACK is abandoned, the 2nd HARQ-ACK is sent in the second up channel.Since the corresponding downstream data channel set of the 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, the network equipment can be while by receiving the 2nd HARQ-ACK to receive a HARQ-ACK, the bit information of HARQ-ACK is eliminated on the first up channel, reduce the effective number of bits for transmitting CSI/SR, coding efficiency is improved, increase the transmission performance of CSI/SR, achieve the purpose that efficiently use uplink control channel, has improved the resource utilization of uplink.If above-mentioned uplink is the uplink of unlicensed spectrum, the utilization rate of unlicensed spectrum resource can be improved.

It is PRACH with the first uplink information, for above-mentioned first up channel is sPUCCH or ePUCCH, in the prior art, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and PRACH on the first up channel, the 2nd HARQ-ACK is sent on the first up channel by the second control information configuration terminal device.At this point, the priority due to HARQ-ACK is high, so terminal device can be abandoned sending PRACH but the first HARQ-ACK of transmission in the first up channel, the 2nd HARQ-ACK is sent in the second up channel.At this point, Since the first up channel and the second up channel are the channel in same uplink, that is the corresponding downstream data channel set of the 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, this mode that the first HARQ-ACK is sent in the first up channel in the prior art, will lead to the waste of the resource of uplink control channel.And uplink signal transmission method provided by the embodiment of the present invention, if the network equipment controls information configuration terminal device by the first control information and third and sends the first HARQ-ACK and PRACH on the first up channel, the 2nd HARQ-ACK is sent on the first up channel by the second control information configuration terminal device, then terminal device can send PRACH in the first up channel, and the first HARQ-ACK is abandoned, the 2nd HARQ-ACK is sent in the second up channel.Since the corresponding downstream data channel set of the 2nd HARQ-ACK includes the corresponding downstream data channel set of the first HARQ-ACK, therefore, the network equipment can be while by receiving the 2nd HARQ-ACK to receive a HARQ-ACK, PRACH can also be received by the first up channel, increase the send opportunity of PRACH, achieve the purpose that efficiently use uplink control channel, has improved the resource utilization of uplink.If above-mentioned uplink is the uplink of unlicensed spectrum, the utilization rate of unlicensed spectrum resource can be improved.

In the prior art, uplink detection reference signal SRS (Sounding reference signal) can be used to estimate the uplink signal-channel quality of different frequency range in eNodeB.At present, the SRS transmission of 2 seed types is defined in LTE, one of which is periodic uplink transmissions SRS (periodic SRS, corresponding trigger type 0), another kind is non-periodic uplink transmissions SRS (aperiodic SRS, corresponding trigger type 1).About aperiodicity uplink SRS, when specific implementation, for FDD, eNodeB can pass through DCI format 0/4/1A triggering terminal equipment and send aperiodicity uplink SRS；For TDD, eNodeB can send aperiodicity uplink SRS by DCI format 0/4/1A/2B/2C triggering terminal equipment.

Currently, the terminal device under LAA-LTE system is when sending aperiodicity uplink SRS, in order to Enough and other systems can be used in conjunction with unauthorized frequency range, terminal device uses first to listen sends out (Listen-Before-Talk afterwards, Channel Access Mechanism referred to as: LBT), before i.e. resource of the terminal device scheduled in being it according to base station sends data, first carry out idle channel evaluation and test (Clear Channel Assessment, CCA) mode evaluates and tests unauthorized frequency range, with determine whether base station be its scheduled in resource on send uplink SRS.If evaluation result is successfully, to illustrate that no any channel sends data using unauthorized frequency range, it is determined that the channel idle in unauthorized frequency range, in this case, terminal device can use unauthorized frequency range to send uplink SRS.If evaluation result is failure, illustrate that there are at least one channels and send data using unauthorized frequency range, it is determined that the channel in unauthorized frequency range is busy, in this case, in order to avoid influencing the data transmission of other channels, terminal device cannot use unauthorized frequency range to send uplink SRS.

The evaluation and test of channel idle performed by terminal device can be divided into two kinds of evaluation and test types:

First evaluation and test type: terminal device listens to channel first, determines channel in a timing period (defer duration) T_fIt is idle state in the time of=16us, then terminal device executes the channel sense of a single time slot, the channel sense period T of the list time slot_sl=9us.If terminal device is in the T_slTime in still detect channel idle, then terminal device is allowed to send data on this channel.Otherwise, if terminal device is in the T_slTime in detect that channel is busy, terminal device is not allowed to send data on this channel.Wherein, terminal device can be by receiving the power on channel compared with energy measuring thresholding, if being higher than pre-determined threshold within the time of the list time slot, and terminal device determines that the channel within the period of the list time slot is busy；If being lower than pre-determined threshold, terminal device determines the channel idle within the period of the list time slot.

Specifically, above-mentioned terminal device is after receiving the first instruction information, it can be determined according to the first instruction information and need to send uplink SRS on the first symbol of the first subframe, and determine that terminal device executes the competition window length of channel idle evaluation and test according to the sub-frame information of first subframe, that is first window length, so that terminal device is when executing channel idle evaluation and test using the first window length, it can be possible to complete the process of channel idle evaluation and test before the time of the first symbol of the first subframe, so that terminal device can be when channel idle be evaluated and tested successfully, uplink SRS is successfully transmitted on the first symbol of the first subframe according to the first instruction information, improve the success rate for sending uplink SRS.

Wherein, the present embodiment does not limit how above-mentioned terminal device according to the sub-frame information of the first subframe determines first window length, such as: above-mentioned terminal device can be according to the sub-frame information of the first subframe, and the mapping relations of preset sub-frame information and length of window, determine first window length, it can also be according to the sub-frame information of the first subframe, from the high-rise length etc. for obtaining first window.The sub-frame information of above-mentioned first subframe includes at least one of following: the downlink symbol quantity in the subframe type of the first subframe, the first subframe.

The subframe type of first subframe mentioned here for example can be special subframe or normal sub-frames.It should be noted that, in the present embodiment, special subframe can be the last one subframe in downlink burst, and first part's symbol in the special subframe is the downlink symbol for sending downlink information, the uplink symbol of uplink information when second part symbol is for occurring.I.e. base station can be used first part's symbol in the special subframe and send downlink data, and terminal device can be used the second part symbol in the special subframe and send upstream data.Optionally, there is protection interval between above-mentioned first part's symbol and second part symbol.The sum of above-mentioned first part's symbol and second part number of symbols are less than or equal to total symbolic number of a special subframe.Optionally, above-mentioned first part's symbol is temporally located at before second part symbol.When specific implementation, the symbol numbers that above-mentioned first part's symbol includes can be for example a value in 3,6,9,10,11,12.There is no transmission of the symbol for downlink information in above-mentioned described normal sub-frames, at least one symbol is transmitted for uplink information.

The sub-frame information of above-mentioned first subframe may include: the downlink symbol quantity in the first subframe.Optionally, if the downlink symbol quantity in the first subframe is greater than 0 and wherein has the symbol for sending uplink information, illustrate that first subframe is special subframe, if the downlink symbol quantity in the first subframe is 0, illustrate that first subframe is normal sub-frames.

The sub-frame information of above-mentioned first subframe can also include: the downlink symbol quantity etc. in the subframe type and the first subframe of the first subframe simultaneously.

S303, terminal device execute channel idle evaluation and test according to first window length；Channel idle evaluation and test is used to determine whether to be allowed to send uplink detection reference signal on the first symbol of the first subframe.

Specifically, terminal device after determining first window length, can execute channel idle evaluation and test, according to the first window length to determine whether to be allowed to send uplink detection reference signal on the first symbol of the first subframe.Wherein, terminal device executes channel idle evaluation and test according to first window length, it specifically may refer to the description in the prior art to the second evaluation and test type, such as: terminal device is according to first window length, it determines that the random back of channel idle evaluation and test counts initial value, and then initial value is counted according to the random back and executes channel idle assessment.

S304, terminal device send uplink detection reference signal on the first symbol of the first subframe when channel idle is evaluated and tested successfully, according to the first instruction information.

Specifically, terminal device is when channel idle is evaluated and tested successfully, illustrate that the resource for being allowed to occupy the first symbol in the first subframe in unlicensed spectrum sends information, in this case, terminal device can send uplink SRS on the first symbol that first indicates the first subframe indicated by information according to the first instruction information.If the evaluation and test failure of terminal device channel idle, terminal device does not send uplink detection reference signal on the first symbol of the first subframe according to the first instruction information.

Above-mentioned channel idle evaluation and test is used to determine whether to be allowed to send uplink detection reference signal on the first symbol of the first subframe.Channel idle, which is evaluated and tested, successfully refers to that terminal device is kept to 0 according to the random back count value that first window length determines before the first symbol of the first subframe, and determines that being allowed to occupy the first symbol in unlicensed spectrum sends uplink information.Channel idle evaluation and test unsuccessfully refers to that terminal device is not yet kept to 0 according to the random back count value that first window length determines before the first symbol of the first subframe, and determines that being not allowed to occupy the first symbol in unlicensed spectrum sends uplink information.

In the prior art, above-mentioned first instruction information instruction terminal equipment is when sending uplink SRS on the first symbol of the first subframe, if above-mentioned first subframe is special subframe, then terminal device is before sending the uplink SRS on the first symbol of the first subframe according to the first instruction information, after needing the special subframe used in base station to send the last one downlink symbol of information data, channel idle test process is completed within the period before the first symbol used in terminal device, the random back count value that competition window length determines is evaluated and tested according to channel idle and is kept to 0.Using the first symbol of the first subframe as the last symbol (i.e. the 14th symbol) of special subframe, for the last one downlink symbol used in the base station is the 12nd symbol of special subframe, then terminal device needs to complete channel idle test process in the 13rd symbol of the first subframe, and transmission signal condition is converted to from receiving state signal, it is possible in channel When free time is evaluated and tested successfully, i.e., in the case that evaluation result is the resource transmission information for being allowed to the first symbol of occupancy, uplink SRS is sent on the first symbol.

At this time, if terminal device executes the length that the competition window length used when CCA is greater than a symbol, then terminal device random back according to caused by the competition window length counts time span corresponding to initial value, it is also possible to time span shared by greater than one symbol.In this way, terminal device also can not complete channel idle test process in the 13rd symbol of the first subframe, cause terminal device that can not send SRS in the first symbol of the first subframe even if unauthorized frequency range is always idle on the 13rd symbol.Specifically: terminal device switchs to the time that transmission state usually requires 20us from reception state.The length of one symbol (including CP) is 71.35us, it is assumed that terminal device is listened in the 13rd semiology analysis L secondary channel.So, in the case where 16 (channel-monitoring delay duration)+9 (single time slot duration) L (number)+20 (reiving/transmitting state conversion duration) < 71.35 us, terminal device is likely to complete channel idle evaluation and test in the 13rd symbol, and switch to transmission state from reception state, uplink SRS is sent in the first symbol, at this point, corresponding to L in above-mentioned formula needs to be less than 3.93.That is, terminal device cannot be greater than 4 using the counting of random back caused by competition window initial value value, in this way, channel idle test process can be completed in the 13rd symbol, and it switch to transmission state from reception state.If the length of competition window is greater than 4, can then there be terminal device random back according to caused by competition window counting initial value and be likely larger than 4, in this case terminal device can not complete channel idle test process in the 13rd symbol, and switch to transmission state from reception state, even if the terminal device subsequent time is caused to complete channel idle test process, since channel idle test process has occupied the time of the first symbol, uplink SRS can not be sent on the first symbol.

And uplink signal transmission method provided in this embodiment, terminal device can determine the length for executing the competition window of channel idle evaluation and test according to the sub-frame information of the first subframe, so that terminal device, which can choose, adapts to the competition window length of the first subframe to execute channel idle evaluation and test, it can be before the first sign-on of the first subframe to improve terminal device, complete the probability of the process of channel idle evaluation and test, so that terminal device can be when channel idle be evaluated and tested successfully, uplink SRS is successfully transmitted on the first symbol of the first subframe, improve the success rate for sending uplink SRS, and then improve the resource utilization of up channel, improve unlicensed spectrum resource utilization.

Uplink signal transmission method provided in an embodiment of the present invention, terminal device receive be used to indicate transmitted by base station terminal device sent on the first symbol of the first subframe uplink SRS first instruction information after, according to the sub-frame information of first subframe determine terminal device execute channel idle evaluation and test contention window Mouth length, so that terminal device can execute channel idle evaluation and test according to the competition window length, to improve terminal device before the first sign-on of the first subframe, complete the probability of channel idle test process, so that terminal device can be successfully transmitted uplink SRS on the first symbol of the first subframe when channel idle is evaluated and tested successfully, the success rate for sending uplink SRS is improved, and then the resource utilization of up channel is improved, improve unlicensed spectrum resource utilization.

Further, on the basis of the above embodiments, what is involved is terminal devices how according to the sub-frame information of first subframe to determine first window length for the present embodiment, then above-mentioned S302 may include: sub-frame information of the terminal device according to the first subframe, and the mapping relations of preset sub-frame information and length of window, determine first window length.

Specifically, terminal device receive be used to indicate transmitted by base station terminal device sent on the first symbol of the first subframe uplink SRS first instruction information after, it can be according to the sub-frame information of first subframe, and the mapping relations of preset sub-frame information and length of window, determine first window length.Wherein, the mapping relations of above-mentioned preset sub-frame information and length of window can specifically be divided into following three kinds of situations:

The first situation: the sub-frame information of above-mentioned first subframe includes: the subframe type of the first subframe, in this case, terminal device can determine the length of first window according to the mapping relations of the subframe type of the first subframe and preset sub-frame information and length of window.The mapping relations of the preset sub-frame information and length of window are the one-to-one relationship of used length of window under every kind of subframe type and the subframe type.For example, the mapping relations of above-mentioned preset sub-frame information and length of window, if may include: the type of the first subframe is special subframe, the corresponding length of window of the first sub-frame information is the first preset value；If the type of the first subframe is normal sub-frames, the corresponding length of window of the first sub-frame information is the second preset value；First preset value is less than the second preset value.Wherein, the specific value of above-mentioned first preset value and the second preset value specifically can according to the structure determination of special subframe and normal sub-frames, such as: above-mentioned first preset value can be 3, above-mentioned second preset value can be 7 etc..In this way, in the last symbol that the first symbol of the first subframe is special subframe, in the case that the last one downlink symbol used in base station is the 12nd symbol of special subframe, the random back for the channel idle evaluation and test that terminal device is determined with the competition window length 3 counts initial value and is centainly not more than 3, as long as channel reality is idle in the 13rd symbol, terminal device can complete channel idle test process in the 13rd symbol, and transmission signal condition is converted to from receiving state signal, in the case that i.e. evaluation result is the resource transmission information for being allowed to the first symbol of occupancy, uplink SRS is sent on the first symbol.And when the first subframe is normal sub-frames, the first symbol is the first son When the last symbol of frame, it is influenced since the process that terminal device executes channel idle evaluation and test is not sent downlink signal by base station in first subframe, terminal device can use bigger competition window length, the process of channel idle evaluation and test is executed in the longer time and is completed from receiving state signal to the conversion for sending signal condition, for example counts initial value for 7 with competition window length come the random back of the channel idle evaluation and test determined and meet the needs of Channel Sharing fairness.The method described in the present embodiment, above-mentioned terminal device can be when the first subframe be different types of subframe, channel idle evaluation and test is executed using different competition windows, it can be before the first sign-on of the first subframe to improve terminal device, complete the probability of channel idle test process, so that terminal device can be when CCA be evaluated and tested successfully, uplink SRS is successfully transmitted on the first symbol of the first subframe, improve the success rate for sending uplink SRS, and then the resource utilization of up channel is improved, improve unlicensed spectrum resource utilization.

Second situation: the sub-frame information of above-mentioned first subframe includes: the downlink symbol quantity in the first subframe, in this case, terminal device can determine the length of first window according to the mapping relations of downlink symbol quantity and preset sub-frame information and length of window in the first subframe.Include downlink symbol quantity in every kind of first subframe in the mapping relations of the preset sub-frame information and length of window with and the corresponding length of window of the quantitative value corresponding relationship.Such as: if the downlink symbol quantity in the first subframe is N1, the corresponding length of window of the first sub-frame information is K1；If downlink symbol quantity in first subframe is N2, the corresponding length of window of first sub-frame information is K2.Wherein N1 and N2 is integer, and N1 is not equal to N2, and K1 is not equal to K2.Different downlink symbol quantity in first subframe may also correspond to identical length of window.Terminal device can determine length of window corresponding with the downlink symbol quantity in the first subframe according to above-mentioned mapping relations.It should be noted that not having transmission of the symbol for downlink information in normal sub-frames, at least one symbol is transmitted for uplink information, therefore downlink symbol quantity is zero in normal sub-frames.Particularly, the mapping relations of above-mentioned preset sub-frame information and length of window, if may include: downlink symbol quantity in the first subframe less than the first default downlink symbol quantity, the corresponding length of window of the first sub-frame information is third preset value；If the downlink symbol quantity in the first subframe is greater than or equal to the first default downlink symbol quantity, the corresponding length of window of the first sub-frame information is the 4th preset value；Third preset value is greater than the 4th preset value.Wherein, above-mentioned first default downlink symbol quantity, and, the specific value of above-mentioned third preset value and the 4th preset value specifically can be according to the structure determination of special subframe and normal sub-frames, such as: above-mentioned first default downlink symbol quantity can be 12, above-mentioned third preset value can be 7, and above-mentioned 4th preset value can be 3 etc..In this way, the first symbol in the first subframe is the last symbol of special subframe, the last one used downlink symbol of base station is the 12nd symbol of special subframe In the case of, the random back for the channel idle evaluation and test that terminal device is determined with the competition window length 3 counts initial value and is centainly not more than 3, as long as channel reality is idle in the 13rd symbol, terminal device can complete channel idle test process in the 13rd symbol, and transmission signal condition is converted to from receiving state signal, in the case that i.e. evaluation result is the resource transmission information for being allowed to the first symbol of occupancy, uplink SRS is sent on the first symbol.And when the first subframe is in the small numbers of situation of downlink symbol in normal sub-frames or the first subframe, it is influenced since the process that terminal device executes channel idle evaluation and test is not sent downlink signal by base station in first subframe, terminal device can use bigger competition window length, the process of channel idle evaluation and test is executed in the longer time and is completed from receiving state signal to the conversion for sending signal condition, for example counts initial value for 7 with competition window length come the random back of the channel idle evaluation and test determined and meet the needs of Channel Sharing fairness.The method described in the present embodiment, above-mentioned terminal device can be in the first subframe when including different downlink symbol quantity, channel idle evaluation and test is executed using different competition windows, it can be before the first sign-on of the first subframe to improve terminal device, complete the probability of channel idle test process, so that terminal device can be when CCA be evaluated and tested successfully, uplink SRS is successfully transmitted on the first symbol of the first subframe, improve the success rate for sending uplink SRS, and then improve the resource utilization of up channel, improve unlicensed spectrum resource utilization.

It should be noted that, the mapping relations of preset sub-frame information and length of window shown under above-mentioned second situation, only a kind of signal, it will be understood by those skilled in the art that, when the sub-frame information of above-mentioned first subframe includes the downlink symbol quantity in the first subframe, the mapping relations of above-mentioned preset sub-frame information and length of window are not limited thereto, such as: the mapping relations that the mapping relations of above-mentioned preset sub-frame information and length of window can be as described in Table 2:

Table 2

Optionally, the mapping relations of above-mentioned preset sub-frame information and length of window may exist diversified forms, such as mapping relations shown in following Table 3:
