3GPP introduces listem-before-talk (Listen Before Talk, LBT) mechanism in LAA, for LTE equipment non- Monitoring and detection idle channel in authorized spectrum band.LBT mechanism is broadly divided into LBT mechanism based on frame structure and based on load LBT mechanism.

The principle of LBT mechanism based on frame structure is referring to Fig. 1, as shown in Figure 1, an idle channel detection cycle includes CCA time, Channel holding time and free time, CCA time are located at most starting for each idle channel detection cycle.LTE is set For before transmitting data, whether monitor channel is idle within the CCA time, if channel idle is in subsequent Channel holding time Interior transmission data, discharge channel within the free time of the detection cycle；If detecting channel busy within the CCA time not Data can be sent in subsequent Channel holding time.The CCA time occupies one or more symbols of subframe, as shown in Figure 1, CCA starts from first symbol of subframe 0.The advantages of LBT mechanism based on frame structure is that implementation is simple, the disadvantage is that data Propagation delay time is larger.

The principle of LBT mechanism based on load referring to fig. 2, in the LBT mechanism based on load, believe by the idle of LTE equipment Road was detected without the fixed cycle, only just carried out idle channel detection in the case where there is data transmission.Before transmitting data, Whether monitor channel is idle on next available initial CCA time immediately for LTE equipment, if channel idle, subsequent Channel holding time in send data, otherwise do not send data；If on the initial CCA time monitor channel be it is busy or Data are not sent complete in Channel holding time, then start to extend the CCA time, letter is detected in each extension CCA time interval Whether road is idle, and extension CCA time interval is identical as initial CCA time span, if detecting channel idle, one secondary channel of note is empty Spare time sends data in subsequent Channel holding time when note is to n times channel idle, does not otherwise send data.Wherein N value For 1 to q integer, wherein q is the competition window length for extending the CCA time, is more than or equal to 4 and is less than or equal to 32.Based on negative The advantages of base station LBT of load is the better performances in heavier loads, and data transmission delay is smaller.

The embodiment of the invention discloses a kind of configuration methods of unauthorized band channels holding time, are implemented using the present invention The technical solution that example provides can be such that UE is matched according to the initial time of up channel holding time and the ascending-descending subframes of TDD system It sets, determines up channel holding time, to carry out data transmission；Or UE can will send data to the UE according to base station Down channel holding time initial time and TDD system ascending-descending subframes configuration, determine that base station will be sent to the UE The down channel holding time of data closes receiver in non-down channel holding time, to realize that terminal saves electric energy Consumption.

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts Example is applied, shall fall within the protection scope of the present invention.

Referring to Fig. 3, Fig. 3 is the configuration method that the embodiment of the present invention one provides a kind of unauthorized band channels holding time Flow diagram, wherein as shown in figure 3, the method that the embodiment of the present invention one provides may include step:

Sub-frame configuration in S101, acquisition TDD LTE system.

Base station and terminal determine the position of ascending-descending subframes according to sub-frame configuration mode in TDD LTE system.TDD LTE The frame structure of system is as shown in figure 4, the radio frames of 10ms include two fields, and half frame length is 5ms, and each field includes 5 Subframe, subframe lengths 1ms, each subframe can be used for upstream or downstream transmission.There are a variety of ascending-descending subframes for TDD LTE system Allocation ratio, i.e., a variety of sub-frame configuration modes can be divided into the sub-frame configuration side of sub-frame configuration mode and 10ms that 5ms is the period Formula.In the sub-frame configuration in 5ms period, subframe 1 and subframe 6 are special subframe, in the sub-frame configuration in 10ms period, subframe 1 For special subframe.Each special subframe by DwPTS, UpPTS and downstream transmission protection interval (Guard Period, GP) group At DwPTS is used for downlink transfer, and UpPTS is used for uplink.4 kinds are with 10ms by the sub-frame configuration in period and 3 kinds of 5ms The sub-frame configuration in period, 6 kinds of subframe configuration modes are as shown in figure 5, wherein " D " indicates that downlink subframe, " U " indicate uplink altogether Frame, " S " indicate special subframe.

Base station notifies TDD system sub-frame configuration mode to receive system to the UE in cell, UE by sending system broadcasts Sub-frame configuration mode used in base station is known after broadcast, to obtain the position of ascending-descending subframes in each radio frames.

In the LTE system of TDD standard, the state that can be also reached according to business carries out flexible TDD configuration, according to business Each subframe is sub-frame of uplink or downlink subframe in arrival state setting subsequent one or multiple radio frames, in such radio frames Uplink, downlink subframe not necessarily occur according to the above-mentioned preset sub-frame configuration mode of 6 kinds of LTE systems.For example, when downlink business compared with When more, the subframe in next radio frames can be all configured to downlink subframe by base station, which can be passed through system by base station Broadcast to the UE in cell.UE can be obtained uplink set by base station, downlink subframe position after receiving system broadcasts.

S102, receive unauthorized frequency range the CCA time instruction message, the instruction message of the CCA time includes uplink The instruction message and the instruction message of downlink CCA time of CCA time.

The instruction message for the unauthorized frequency range CCA time that UE is sent by reception base station, can be detected unauthorized letter The CCA time in road.The instruction message of the CCA time includes the instruction message and the instruction of downlink CCA time of uplink CCA time Message.UE obtains the CCA time that UE detects unauthorized frequency range by the instruction message of uplink CCA time, passes through the downlink CCA time Instruction message can get base station and detect CCA time of unauthorized frequency range.

The LBT mechanism based on frame structure and the LBT machine based on load can be used in TDD LTE system in unauthorized frequency range System.

Under the LBT mechanism based on frame structure, there is the fixed period in the CCA time, when can be by CCA time span, CCA Between offset, the CCA time cycle determine the CCA time.Subframe where the CCA time can be determined by following formula, when frame number and There is the CCA time in subframe numbers when meeting the formula:

[(FrameNum × 10)+SFN] %N_{CCA_Cycle}=N_{CCA_Offset}

Wherein, N_{CCA_Cycle}For CCA time cycle, N_{CCA_Offset}For the sub-frame offset of CCA time.

Under LBT mechanism based on frame structure, the configuration information of CCA time is determined by base station, comprising: CCA time span, CCA time sub-frame offset, CCA time cycle.The CCA time of UE can be configured on the GP of special subframe, special subframe On UpPTS or sub-frame of uplink, the DwPTS that the CCA time of base station can be configured in special subframe, downlink subframe or closely downlink On the sub-frame of uplink of frame.The configuration information of above-mentioned CCA time is sent to UE by the instruction message of CCA time by base station.UE from The configuration information that the CCA time is obtained in the instruction message of the CCA time, can determine each period CCA time by above formula Initial time.Base station the instruction message of the instruction message of uplink CCA time and downlink CCA time can be placed on same without UE is sent in line resources control (Radio Resource Control, RRC) reconfiguration message；It base station can also be by uplink The instruction message of CCA time is placed in RRC reconfiguration message and is sent to UE, and the instruction message of downlink CCA time is placed on system UE is sent in broadcast.UE can obtain CCA time and the unauthorized frequency of base station detection that UE detects unauthorized frequency range as a result, The CCA time of section.In up direction, base station is permitted in (Uplink Grant) signaled UE transmission by sending uplink authorization The resource location of row data and triggering UE starting idle channel detection.

Under the LBT mechanism based on load, initial CCA time span, initial CCA time initial time, channel can be passed through Holding time length and extension CCA race length of window q, wherein q is the integer for being less than or equal to 32 more than or equal to 4, is come true The CCA time of fixed unauthorized frequency range, CCA time include initial CCA time and extension CCA time.UE is 1 to selecting at random between q An Integer N is taken, within the extension CCA time, if detecting channel idle, N is made to subtract 1, otherwise N is constant, when N is kept to 0, expands The exhibition CCA time terminates, and into Channel holding time, starts to send data.Under LBT mechanism based on load, the CCA time of UE Configuration information is determined by base station, comprising: initial CCA time span, the competition window length q for extending the CCA time.Base station passes through The configuration information of above-mentioned CCA time is sent to UE by RRC reconfiguration message, and UE is allowed to obtain the configuration information of above-mentioned CCA time.? Up direction, by sending, Uplink Grant signaled UE sends the resource location of upstream data and triggering UE is opened for base station Begin detection idle channel, that is, starts the initial CCA time, and initial CCA time and extension CCA time can be located at special subframe The UpPTS or sub-frame of uplink of GP, special subframe.The instruction message of uplink CCA time includes carrying CCA time configuration information RRC reconfiguration message and the Uplink Grant signaling.Special subframe can be located in the CCA time of down direction, base station DwPTS, downlink subframe or closely on the sub-frame of uplink of downlink subframe, after detecting channel idle, can pass through and send channel Reserved signaling (Reservation Signal) instruction base station UE will use subsequent downlink subframe to send downlink data to UE, Reservation Signal occupies one or several symbols of a downlink subframe, and UE receives the Reservation It is may know that after Signal in some symbol of the current downlink subframe for receiving the Reservation Signal or next Nearest downlink subframe base station starts busy channel and sends downlink data, therefore under the LBT mechanism based on load, downlink CCA The instruction information of time refers to the Reservation Signal.

S103, according to the instruction message of the sub-frame configuration and the CCA time, determine the channel in unauthorized frequency range Holding time, to carry out data transmission and data receiver according to the Channel holding time.

The determination method of up channel holding time specifically includes:

According to the sub-frame configuration mode that step S101 is obtained, UE can be determined can carry out uplink in each radio frames Position, to obtain continuous uplink transmission time under the sub-frame configuration mode in radio frames, when continuous uplink Between include special subframe in UpPTS and the UpPTS after continuous sub-frame of uplink.

According to the instruction message of uplink CCA time received in step S102, it may be determined that up channel holding time rises Begin the moment.Under the LBT mechanism based on frame structure, each period occurs known to the configuration information that UE passes through the uplink CCA time The specific location of CCA time.When UE receives Uplink Grant, if by the Uplink Grant instruction sub-frame of uplink with The sub-frame of uplink of last Uplink Grant instruction is not belonging to the continuous sub-frame of uplink in sub-frame configuration, then in Uplink The nearest CCA time before continuous sub-frame of uplink where the sub-frame of uplink of Grant instruction starts idle channel detection, will be described The finish time of CCA time is set as the initial time of next up channel holding time；If being referred to by the Uplink Grant The sub-frame of uplink for sub-frame of uplink and last time Uplink the Grant instruction shown belongs to the continuous sub-frame of uplink in sub-frame configuration, says Bright reception last time Uplink Grant has triggered idle channel detection when indicating, and this Uplink Grant instruction is upper Row subframe belongs to the Channel holding time after idle channel detection, therefore this Uplink Grant does not have to trigger the free time again Channel Detection.Under the LBT mechanism based on load, when UE receives UpLink Grant signaling, if by the Uplink The sub-frame of uplink that the sub-frame of uplink and last time Uplink Grant of Grant instruction indicate is not belonging on continuous in sub-frame configuration Row subframe, then Uplink Grant instruction sub-frame of uplink where continuous sub-frame of uplink before nearest protection interval GP, UpPTS or sub-frame of uplink starting idle channel detection, start initial CCA, then the finish time of the CCA time are set as next The initial time of a up channel holding time；If by the sub-frame of uplink and last time Uplink of Uplink Grant instruction The sub-frame of uplink of Grant instruction belongs to the continuous sub-frame of uplink in sub-frame configuration, illustrates that receiving last Uplink Grant refers to Idle channel detection is triggered when showing, and the sub-frame of uplink of this Uplink Grant instruction belongs to the idle channel and detects it Channel holding time afterwards, therefore this Uplink Grant no longer triggers idle channel detection.It is detected when in the initial CCA time To channel is not idle or Channel holding time when the initial CCA time after in UE do not complete data and send, then start extension CCA is the initial time of up channel holding time next time at the end of extending the CCA time.

Continuous uplink transmission time after the initial time of above-mentioned up channel holding time is set as up channel Holding time.For example, when in the GP for being located at special time slot when the CCA time, on by the UpPTS after the GP and its later several Row subframe is set as up channel holding time；It is located in UpPTS time slot when the CCA time, it will be remaining after the CCA time Sub-frame of uplink after the UpPTS and UpPTS is set as up channel holding time.

The determination method of down channel holding time specifically includes:

Under LBT mechanism based on load, the configuration information of uplink CCA time includes: initial CCA time span, extension CCA The competition window length q of time.The configuration information of uplink CCA time is sent to UE by RRC reconfiguration message by base station, allows UE Obtain the configuration information of above-mentioned CCA time.Base station sends the money of upstream data by sending Uplink Grant signaled UE Source position and triggering UE start to detect idle channel, that is, start initial CCA.Initial CCA time and extension CCA time can positions In the GP of special subframe, the UpPTS of special subframe or sub-frame of uplink.For example, 20us is configured by the initial CCA time, expanded The competition window length for opening up the CCA time is 4.UE starts initial CCA after receiving Uplink Grant, if UE is received in subframe 6 To the Uplink Grant signaling to subframe 2, it should which nearest GP, UpPTS or sub-frame of uplink carry out idle letter before subframe 2 Road detection, i.e., carry out idle channel detection when the GP of subframe 1 starts.

S303, according to the sub-frame configuration, obtain the continuous uplink transmission time under the sub-frame configuration in radio frames.

According to the sub-frame configuration obtained in step S301, UE can determine the position of sub-frame of uplink, to obtain in the son The lower continuous uplink transmission time of frame configuration, after continuous uplink transmission time includes UpPTS and the UpPTS in special subframe Continuous sub-frame of uplink.As shown in fig 8-a, according to sub-frame configuration 0, continuous uplink transmission time includes in each special subframe UpPTS and continuous 3 sub-frame of uplink later.

S304, up channel holding time is determined according to the configuration information and Uplink Grant signaling of uplink CCA time Initial time.

Son when UE receives Uplink Grant signaling, where the sub-frame of uplink of Uplink Grant signaling instruction Starting idle channel detection in the nearest CCA time before continuous sub-frame of uplink in frame configuration, by the end of the CCA time Moment is set as the initial time of up channel holding time.

As shown in Fig. 8-b, in the example of the above LBT mechanism based on frame structure, the CCA time is configured in special subframe GP, CCA time span are 20us, and the CCA time cycle is configured to 5ms, it is known that it is each special that UE each possible CCA time is located at 20us in GP before the UpPTS of subframe starts.UE receives the Uplink Grant signaling to subframe 2 in subframe 6, therefore Idle channel detection is carried out in the GP of subframe 1, idle channel is detected into finish time, i.e. the initial time of the UpPTS of subframe 1 is set It is set to the initial time of up channel holding time.

As shown in Fig. 8-c, in the example of the above LBT mechanism based on load, the initial CCA time is configured to 20us, works as UE It receives Uplink Grant and starts initial CCA later, if UE receives the Uplink Grant signaling to subframe 2 in subframe 6, answer Initial CCA should be started in next possible CCA time, i.e., initial CCA be carried out when the GP of subframe 1 starts, after GP is started 20us is set as the initial time of up channel holding time.

S305, the continuous uplink transmission time after the initial time of up channel holding time is set as up channel Holding time.

As shown in Fig. 8-b, in the example of the above LBT mechanism based on frame structure, when the starting of up channel holding time The initial time for carving the UpPTS for subframe 1, will be set as since the UpPTS of subframe 1 to subsequent 3 continuous sub-frame of uplink Up channel holding time.
