First TA value of UE configuration;Alternatively, only receiving the 2nd TA value that base station transmission is UE configuration;Alternatively, both having received base station transmission
It is the first TA value of UE configuration, also receives the 2nd TA value that base station transmission is UE configuration.
It should be noted that it is what UE was configured that the first TA value, which can be macro base station, and sent to UE, or macro base
It stands and is configured for UE, micro-base station is sent to by the air interface between macro base station and micro-base station, then micro-base station is sent to UE.
2nd TA value can be what micro-base station was what UE was configured, and was sent to UE, or micro-base station is UE configuration, passes through macro base station
Air interface between micro-base station is sent to macro base station, is then sent from macro base station to UE.
TA indicates that UE sends the lead of uplink signal.For example, uplink signal transmitted between UE and transmitting-receiving node away from
From for D, transmitting-receiving node wishes that then UE is needed in (T0-T in the uplink signal that T0 reception to UE is sentTA) moment send on
Row signal.Wherein, TA is to determine the time for sending uplink signal to base station according to UE, and the value of TA is D/c, and c indicates electromagnetism
The speed of wave transmission.Since UE has mobility, uplink signal transmits distance D also in UE between transmitting-receiving node to be changed,

Shift to an earlier date N on the basis of uplink signal windowRXadjustmentTime;
Wherein, as the NTAadjustmentWhen for fixed value, the NRXadjustment>=the NTAadjustment;Alternatively, described
NTAadjustmentWhen for changing value, the NRXadjustment≥max(ΔTUE-n), n=1,2,3 ..., N, wherein Δ TUE-nIt is n
UE sends the time difference used in uplink signal to the macro base station and the micro-base station, and N is to send uplink signal respectively described in
The number of macro base station and the UE of the micro-base station.
It should be noted that the execution sequence of step 307 and step 308 does not limit, it can step 307 is first carried out,
Step 308 can be first carried out, also may be performed simultaneously step 307 and step 308.
Step 309, UE regularly sends the uplink signal according to the transmission after adjustment.
Optionally, when sending the uplink signal, k-th up-link wireless subframe shifts to an earlier date with corresponding downlink wireless sub-frame
(NTA+mk×NTAadjustment+NTA offset)×TsSecond sends;Wherein, the NTAIndicate the institute that the base station configures for the UE
State TA value;The NTAadjustmentIndicate the adjustment Timing Advance;The NTA offsetIndicate timing advance offset;Work as institute
State mkValue be 0 when, indicate that the k-th up-link wireless subframe is sent to the macro base station, as the mkValue when being 1, indicate this
K up-link wireless subframe is sent to above-mentioned micro-base station;The TsFor a coefficient.
Step 310, micro-base station receives uplink signal window by described second, receives the uplink signal that the UE is sent.

Since the present invention only adjusts the timing for the uplink signal for being sent to micro-base station, macro base station can be according to
The mode of the prior art receives the uplink signal of UE transmission, and demodulates to the uplink signal received.
It is illustrated in figure 4 the scene that micro-base station is deployed in the coverage area of macro base station.Wherein, UE-0, UE-1, UE-2
Uplink signal, which needs to be sent to macro base station and is sent between micro-base station, to be switched, and the uplink signal of UE-3 needs to be sent to micro- base
It stands.Time difference used in the uplink signal arrival macro base station and arrival micro-base station of UE-0, UE-1, UE-2 is respectively Δ TUE-0、Δ
TUE-1With Δ TUE-2, and have Δ TUE-0< Δ TUE-1< Δ TUE-2。

NTAadjustment) adjustment timing.
Network side: it is RX that macro base station, which receives uplink signal window,window1;Micro-base station receives uplink signal window
RXwindow2 shift to an earlier date NRXadjustment。
As the NTAadjustmentWhen for fixed value, the NRXadjustment>=the NTAadjustment;Alternatively, described

On again shift to an earlier date NTAadjustment, micro-base station reception uplink signal window ratio RXwindow2 shift to an earlier date NRXadjustment, can be properly received simultaneously
Demodulate uplink signal.It should be noted that as shown in figure 5, NTAadjustmentGreater than Δ TUE-0When, then UE send uplink signal
When being sent to macro base station and switching to be sent to micro-base station, the uplink signal for being sent to two base stations can be overlapped, therefore, it is necessary to
NTAadjustmentNo more than Δ TUE-0, then the uplink signal that UE is sent is sent to two when being sent to macro base station and switching to be sent to micro-base station
The uplink signal of base station will not overlap.
And when the prior art being used to send uplink signal, the uplink signal for being sent to macro base station is believed than being sent to the uplink of micro-base station
Number in advance Δ TUE-0, so that sending the Xiang Hongji that is about to begin when signal is not yet completed to micro-base station in UE on certain periods
It stands and sends signal, is i.e. the signal of macro base station and micro-base station is overlapping.Since UE transmission power is limited or two signals are mutual
The reason of interference, needs to abandon one of uplink signal, and the uplink signal for being dropped a side is caused correctly cannot to demodulate or solve
Adjust poor performance.Therefore it is not handed over as far as possible using the signal that method provided in an embodiment of the present invention can make UE be sent to two base stations
It is folded, to improve demodulation performance.
In addition, for UE-3, when only sending uplink signal to micro-base station due to UE-3, the upper of micro-base station will be sent to
Row signal shifts to an earlier date N again on the basis of two TA in advanceTAadjustment, therefore micro-base station receives uplink signal window ratio RXwindow2
N in advanceRXadjustment, can be properly received and demodulate uplink signal.
The embodiment of the present invention provides a kind of method of uplink signal transmissions timing, passes through the side UE and micro-base station side basis respectively
The N of acquisitionTAadjustmentAdjustment sends the timing of uplink signal and receives uplink signal window, allows to correctly demodulation and connects
The uplink signal received improves the demodulation performance of uplink signal.
