Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In traditional technology, by taking the deployment scenario in Fig. 1 as an example, it is contemplated that two LAA cells (base station LAA 1 and the base stations LAA
2) example coexisted with a WiFi system, the user that wherein base station LAA 1 services is terminal 1 and 2；The end that the base station LAA 2 services
End is terminal 3；The terminal of the AP service of WiFi is terminal 4.These three cells can work on the same channel, need to compete
It goes using channel resource.According to the mode that tradition is competitive channel resource in technology go distribution channel resource, due to terminal it
Between interference be difficult competition to channel resource, to cause the low utilization of resources so that the success rate that terminal is LBT is lower
The problem of.
Therefore, to solve in the LAA system in traditional technology mentioned above, terminal is occupied in uplink transmission data
The chance of channel is less, so that the technical problem of the utilization rate deficiency of channel resource proposes one kind and be based in the present embodiment
The data transmission method of uplink multiplexing, this method, which can be dependent on, supports the mobile terminal of LAA system to realize.
Specifically, as shown in Fig. 2, this method comprises:
Step S102: when preset detection time slot arrives at, whether detection uplink transport channel is occupied.
In LAA system, terminal can detect the uplink that data are uploaded to base station when preset detection time slot arrives at
Whether transmission channel is occupied, and whether terminal is occupied using LBT mechanism detection uplink transport channel, can be used FBE's or LBE
Whether mode detects in uplink transport channel has other terminals uploading data to base station.In FBE mode, terminal can be periodical
Ground by LBT mechanism detect uplink transport channel it is whether occupied, it is preset detection time slot as periodically arrive at it is multiple when
Gap section, when at the time of periodically arriving at corresponding to detection time slot, above-mentioned detection uplink transport channel, which can be performed, is
No occupied process.And in the mode of LBE, can according to business needs, when the detection time slot that upper-layer service defines arrives at,
Execute the whether occupied process of above-mentioned detection uplink transport channel.
As shown in figure 3, Fig. 3 illustrates orthogonal frequency division multiplexi (English: Orthogonal Frequency
Division Multiplexing, referred to as: OFDM) i.e. data transmission in frame structure, terminal to the data that base station is sent be more
The structure of a subframe, each subframe include time interval resource.Each subframe includes multiple OFDM symbols (symbol), each
The i.e. corresponding corresponding time interval resource of OFDM symbol.In LAA system, terminal can be in some of some preset OFDM subframe
When the time slot of OFDM symbol arrives at the time of correspondence, whether detection uplink transport channel is occupied, and the time slot is as preset
Detect time slot.
In the present embodiment, can by clear channel assessment (CCA) (English: Clear Channel Assessment, referred to as:
CCA) whether detection uplink transport channel is occupied.In a wireless communication system, when equipment needs to send number on a certain channel
It according to before, is received on this channel first, if not found other equipment in this channel by the given time
Upper transmission data, then determine the channel idle；If it find that thering are other equipment sending data, then at random after evacuation a period of time
This process is retried again.This method can be effectively prevented from the conflict on wireless channel, also referred to as have the carrier frequency of conflict avoidance
Listen to multiple access (Carrier Sense Multiple Access with Conflict Avoidance, CSMA/CA).
Step S104: when detecting that uplink transport channel is unoccupied, preset occupancy data are generated.
Step S106: in the upload time slot for obtaining base station distribution, after detecting that uplink transport channel is unoccupied the
Before one upload time slot arrives at, the occupancy data are sent by the uplink transport channel.
In the present embodiment, base station can be unauthorized for multiple terminal distributions of its service according to the idle condition of channel resource
Time interval resource on frequency spectrum, enables the terminal to when corresponding time interval resource arrives at, and is uploaded by unlicensed spectrum to terminal
Data.As shown in figure 3, base station can (channel resource of base station be possibly used for other industry such as downlink data transmission at this time in subframe N-4
Business) at the time of notice terminal subframe N two time slot positions of symbol4 and symbol11 can be used as upload data initial time
Position, base station can send radio resource control RRC signaling, MAC CE or physical layer signaling on authorization frequency spectrum or unlicensed spectrum
(broadcast or individually sending) is sent to all terminals on the channel, terminal receives base station in authorization frequency spectrum or unauthorized frequency
Radio resource control RRC signaling, MAC CE or the physical layer signaling of transmission in spectrum, parsing obtain the upload of the base station distribution
Time slot, i.e. two time slots of symbol4 and symbol11 of subframe N.
If the base station for sending the upload Time slot allocation situation is the base station 1 in Fig. 1, as previously described, because above-mentioned LAA system
In system, tri- base station LAA 1, the base station LAA 2 and wifi cell operations on the same channel, therefore, terminal 1, terminal 2, terminal 3
It needs to compete with terminal 4 and uses channel, if mode conventionally carries out resource contention, the competition of terminal 3 and terminal 4
Behavior can interfere terminal 1 and terminal 2.
In the present embodiment, to avoid above-mentioned interference, if as shown in figure 3, terminal 1 using the symbol8 time slot of subframe N as
Detect time slot, carry out LBT, passed through CAA verification, then can determine that the channel the symbol8 of subframe N time slot position for free time
State, at this point, terminal 1, which can constantly be sent in the time slot position of the symbol9 of subframe N using the uplink transport channel, occupies number
According to.For terminal 3, if terminal 3 subframe N the position symbol9 carry out LBT, detect the uplink transport channel whether by
It occupies, then occupied by the occupancy data sent by terminal 1 as the uplink transport channel, terminal 3 can not pass through
CAA verification, will determine always that uplink transport channel is in occupied state.
Step S108: first upload time slot after detecting that the uplink transport channel is unoccupied arrives at
When, business data transmission is carried out by the uplink transport channel.
In upper example, terminal 1, will be by upper after detecting that uplink transport channel is in idle when gap arrives at when detecting
Row transmission channel, which is persistently sent, occupies data, i.e., persistently sends occupancy in the time slot position of symbol9, symbol10 of subframe N
Data so that the equipment of other cells such as terminal 3 determines that the upload transfers channel is occupied, therefore not will use upload biography
Defeated channel sends data to base station.But when the symbol11 time slot of subframe N arrives at, since the time slot is that base station is pre-assigned
The initial position of uplink transmission data, then terminal 1, which terminates to send, occupies data, and transfers to send the business datum for needing to send extremely
Base station, to complete the upload of data.And for terminal 3, since its uplink transport channel being continuously detected is quilt
Occupied state, then terminal 3 not will use the uplink transport channel and send data, thus will not upload behavior to terminal 1 carry out
Interference.
In the present embodiment, in order to allow same cell terminal reusable unlicensed spectrum same time interval resource in it is upper
Row transmission channel, terminal also can receive before detecting the whether occupied step of uplink transport channel the base station issue it is pre-
If signal characteristic corresponding with affiliated subdistrict, which is predefined or by receiving base station in authorization frequency spectrum or non-
What RRC signaling, MAC CE or the physical layer signaling sent on authorization frequency spectrum was known；
And terminal generates that the step of preset occupancy data may further be embodied as receiving according to and affiliated subdistrict pair
Induction signal feature, which generates, occupies data.
Further, it can also be issued according to the base station before the terminal detection whether occupied step of uplink transport channel
Preset signal characteristic corresponding with affiliated subdistrict the data in the uplink transport channel are offset.
In other words, as shown in Figure 1, the base station LAA 1 can first pass through RRC signaling in advance or physical signaling will be right with the base station LAA 1
The signal characteristic answered is sent to terminal 1 and terminal 2 (base station LAA 1 is cell base station belonging to terminal 1 and terminal 2), such as LAA
The cell ID of base station 1；The base station LAA 2 can first pass through RRC signaling in advance or physical signaling will signal characteristic corresponding with the base station LAA 2
It is sent to terminal 3 (base station LAA 2 is cell base station belonging to terminal 3), such as the cell ID of the base station LAA 2.
Terminal 1 then passes through uplink when detecting that the uplink transport channel of unlicensed spectrum is vacant in the execution above method
Transmission channel uploads the cell ID of the base station LAA 1 as occupancy data；Terminal 2 detects non-award in the subsequent execution above method
It, then can be first using the cell ID of the base station LAA 1 in uplink transport channel when whether the uplink transport channel of power frequency spectrum is occupied
Occupancy data offset, if offsetting successfully, also determine unlicensed spectrum uplink transport channel be unoccupied state,
Optionally, above-mentioned steps S104 can also be continued to execute, sends the base station LAA 1 using the uplink transport channel of the unlicensed spectrum
Cell ID.
And for terminal 3, since it goes the uplink for offsetting unlicensed spectrum to pass by the cell ID of the base station LAA 2
The cell ID of the base station LAA 1 on defeated channel can not succeed, therefore, the base station LAA in the uplink transport channel of unlicensed spectrum
1 cell ID is the transmission data in the uplink transport channel of unlicensed spectrum for terminal 3, and terminal 3 is by uplink
Transmission channel is occupied, and terminal 3 can be abandoned occupying the uplink transport channel at this time, and continue to detect.
Specifically, as shown in figure 4, base station 1 by authorization frequency spectrum or unlicensed spectrum broadcast subframe N symbol4 and
Symbol1 is to upload time slot, and the detection time slot of terminal 1 is symbol6, and the detection time slot of terminal 2 is symbol8, the inspection of terminal 3
Survey time slot is symbol8, therefore, when the symbol4 time slot of subframe N arrives at, since terminal 1, terminal 2 and terminal 3 are not opened
Beginning is LBT and detects to uplink transport channel, therefore, in the symbol4 time slot of subframe N, occupies uplink without terminal and passes
Defeated channel uploads data to base station.And when the time arriving at the symbol6 time slot of subframe N, terminal 1 starts detection and is LBT to this
The uplink transport channel of unlicensed spectrum is detected, if having passed through CAA verification, determines the uplink of the unlicensed spectrum
Channel is unoccupied, and begins to use the uplink transport channel of the unlicensed spectrum to send in the symbol7 time slot of subframe N
The cell ID of the base station LAA 1.
When the time arriving at the symbol8 time slot of subframe N, terminal 2 starts the uplink for being LBT to the unlicensed spectrum
Channel is detected, and is first offset using the cell ID of the base station LAA 1 to the uplink transport channel of the unlicensed spectrum,
Since terminal 1 starts just persistently to send LAA using the uplink transport channel of the unlicensed spectrum in the symbol7 time slot of subframe N
The cell ID of base station 1, therefore, terminal 2 are cancelled by the data that the uplink transport channel of the unlicensed spectrum receives, from
And verified also by CAA, terminal 2 can also start the lasting uplink transport channel using the unlicensed spectrum and send the base station LAA 1
Cell ID begins to use the uplink transport channel of the unlicensed spectrum to send the base station LAA 1 in the symbol9 time slot of subframe N
Cell ID.
Equally, when the time arriving at the symbol8 time slot of subframe N, terminal 3 also starts to be LBT to the unlicensed spectrum
Uplink transport channel is detected, and first using the base station LAA 2 cell ID to the uplink transport channel of the unlicensed spectrum into
Row is offset, since terminal 1 and terminal 2 start that the uplink of the unlicensed spectrum is just persistently used to pass in the symbol7 time slot of subframe N
Defeated channel sends the cell ID of the base station LAA 1, and therefore, terminal 2 is received by the uplink transport channel of the unlicensed spectrum
The cell ID of the base station LAA 1 can not be offset by the cell ID of the base station LAA 2, so that terminal 3 can not be verified by CAA, thus
Determining that the uplink transport channel of the unlicensed spectrum is occupied, terminal 3 can abandon occupying the uplink transport channel at this time, and after
It is continuous to be detected.
When the time arriving at the symbol11 time slot of subframe N, since the time slot is the upload time slot that base station 1 is distributed,
Terminal 1 and terminal 2 transmit data to base station in the uplink transport channel that the moment is all made of the unlicensed spectrum.
It can be seen that by the above process, terminal 1 or terminal 2 in the same cell can be corresponding with the cell by sending
Data are occupied, prevent the terminal of other cells from occupying the channel resource transmission data of the base station distribution of the cell (since other are small
The terminal in area is not the service object of the base station of the cell, can be dropped uploading yet, be accordingly changed into interference signal), and it is same
The terminal 1 or terminal 2 of one cell can also occupy data by cancelling out each other, and determine the uplink transport channel of unlicensed spectrum
To be unoccupied, when the upload time slot so as to distribute in the base station of the cell arrives at, it is multiplexed the channel resource of the base station, thus
It improves resource utilization.
It should be noted that this method can be executed by same terminal in the execution of the above method, in example as above, at one
In LAA system, a terminal both may use the uplink of unlicensed spectrum to believe as the identity of the terminal 1 in examples detailed above
Road, which is sent, occupies data, it is also possible to as the identity of the terminal 2 in examples detailed above, according to signal characteristic pair corresponding with affiliated subdistrict
The uplink transport channel of unlicensed spectrum is offset, and offsets success；It may also be as the body of the terminal 3 in examples detailed above
Part, the uplink transport channel of unlicensed spectrum is offset according to signal characteristic corresponding with affiliated subdistrict, and offset failure.
In addition, terminal is occupied in uplink transmission data to solve in the LAA system in traditional technology mentioned above
