Priority, it is only necessary to intercept a time interval for being not less than X us (such as 25us), base station is that can be transmitted
DRS。
FDD (FDD, Frequency Division Dual) up-downgoing is sent by different frequency point
Open.Traditional time division duplex (TDD, Time Division Duplexing) is in addition to special subframe, up and down
It is to configure to send to coordinate up-downgoing by different ascending-descending subframes in different subframes that row, which is sent,.For same
The up-downgoing of one unauthorized carrier wave is sent, and the up-downgoing in such as LAA is natural TDD, but different
In traditional TDD isolated by fixed ascending-descending subframes configuration, but a kind of similar dynamic TDD
Sending method, it is not necessary to isolated by fixed subframe up-downgoing transmission, and can by LBT/ free time believe
The influence of road detection (CCA, Clear Channel Assessment).When UE sends upward signal/channel,
Need to consider the descending DRS to base station or DMTC influence, how to coordinate the transmission of upward signal/channel
Transmission with descending DRS or DMTC is the problem of having to be solved.

Embodiment
The characteristics of in order to more fully hereinafter understand the embodiment of the present invention and technology contents, below in conjunction with the accompanying drawings
Realization to the embodiment of the present invention is described in detail, appended accompanying drawing purposes of discussion only for reference, is not used for
Limit the embodiment of the present invention.
DRS can be used for cell searching, synchronization and/or RRM measurements etc..Be not turned on even in cell or
In the case of there is no business transmission, if there is no DRS in LAA or small cell on/off scenes,
Compete unauthorized carrier wave send after data or cell open after synchronize again with RRM measurement, then can
The larger synchronization of cost and time of measuring, so that spectrum efficiency can be reduced.
In Rel-13, DRS has higher LBT priority, it is only necessary to intercepts one and is not less than X us
The time interval of (such as 25us), base station is transmittable DRS.In Rel-12/13 versions, DMTC's
Cycle is 40/80/160ms, and duration duration is 6ms.Therefore, the DRS in longer transmission cycle
Influence is sent to data using the LBT modes of higher priority little.
In LAA, even if up-downgoing can be transmitted in same subframe, it is also desirable to consider up transmission
Influence between DRS transmissions.Sent to coordinate up transmission and DRS, it is ensured that unauthorized carrier wave system
The performance of system can be unaffected, and the embodiments of the invention provide a kind of sending method of upward signal/channel.
The sending method of upward signal/channel of the embodiment of the present invention is applied to all unauthorized carrier systems, no
It is limited to LAA systems.For the ease of description, the embodiment of the present invention is used as unauthorized carrier wave system using LAA systems
One typical case's application of system is described.
So that upward signal/channel is SRS as an example, SRS can individually be sent, can also be with other up channels
Send together.SRS has the cycle to send and aperiodic transmission two ways (namely trigger type 0 and trigger
type 1).SRS sends in the last symbol of subframe and (taken for TDD ascending pilot frequencies (UpPTS)
2 single-carrier frequency division multiple access (SC-FDMA, Single Carrier-Frequency Division Multiple
Access) symbol, the two symbols may be used to SRS transmission).SRS cycle is in 2ms to 320ms
Between (trigger type 0/1 and FDD/TDD have nothing in common with each other).
LAA DRS take preceding 12 OFDMs (OFDM, the Orthogonal of each subframe
Frequency Division Multiplexing) symbol, most latter two OFDM symbol of subframe can be used for
CCA, and SRS is sent in the last symbol of subframe, and SRS cycles minimum 2ms.If SRS
Sent in DMTC, then can reduce DRS send opportunity.
Fig. 1 is the schematic flow sheet of the sending method of upward signal/channel of the embodiment of the present invention, such as Fig. 1 institutes
Show, the sending method of the upward signal/channel comprises the following steps：
Step 101：According to the subframe position, do not sent in DRS subframes and/or DMTC subframes
Row signal/channel；Or, do not send upward signal in DRS subframes and/or DMTC subframes setting symbol
/ channel；Or, preferentially send upward signal/channel in DRS subframes and/or DMTC subframes；Or,
Indicate whether to send DRS in DRS subframes and/or DMTC subframes by downlink signaling, and/or whether send out
Send the information of up channel/signal.
Here, the DMTC duration is 6ms, namely generally comprises 6 subframes.Having in DMTC can
DRS can be only sent in the subframe of part, this point depends on DRS sending strategy and LBT results.Example
Such as, DRS only needs to be successfully transmitted in each DMTC once, is not sent if channel is to hurry always.
Further, DRS only needs to first idle subframe transmission in each DMTC.So in DMTC
In first idle subframe then preferentially send DRS, upward signal/channel is not sent.But in DMTC
Other idle subframe base stations without send DRS when, then can be used for send upward signal/channel.
Another method is, although base station is possible to only send in part DRS subframes or DMTC subframes
DRS, it is contemplated that the DRS of adjacent area is sent and whether UE sends DRS presence to local area/adjacent area
Judge possibility by accident, therefore can not send up at the first subframe position where DRS and/or DMTC
Signal/channel.According to this method, DMTC 6 subframes do not send upward signal/channel no matter
Whether 6 subframes in the DMTC, which are all used for DRS, sends.
In one embodiment, it is described not send upward signal in DRS subframes and/or DMTC subframes
/ channel, including：
Change up channel/signal and/or change DMTC configuration send configuration, with avoid up channel/
Signal configuration is sent in DRS subframes and/or DMTC subframes.
Or, modification Sounding Reference Signal SRS configuration, to avoid SRS from matching somebody with somebody with DMTC/DRS
Put identical subframe.
In present embodiment, upward signal/channel can be Sounding Reference Signal (SRS, Sounding
Reference Signal), the send configuration to SRS is limited or changed, it is to avoid SRS and DMTC or
DRS is configured to identical subframe.Or, DMTC send configuration can also be limited or changed,
SRS and DMTC or DRS is avoided to be configured to identical subframe.
Configuration based on DMTC, the send configuration to SRS is limited or changed specially：
DRS DMTC cycle (period) is 40/80/160ms in Rel-12/13, is offset (offset)
Scope is 0~(period-1) ms, and the duration (duration) is 6ms.So DMTC is appeared in
The subframe [mod (DMTC-offset, 10)] of each radio frames to subframe [mod (mod (DMTC-offset,
10)+5,10)].Such as DMTC-offset is 1, then DMTC scope is that subframe 1 arrives subframe 6.
If DMTC-offset is 7, then DMTC scope is the subframe 2 that subframe 7 arrives next radio frames,
Totally 6 subframes.
, can be in Rel-10~13 of 3GPP 36.211 to avoid SRS and DMTC from being configured to identical subframe
The configuration of srs-SubframeConfig in Table 5.5.3.3-1 and/or Table 5.5.3.3-2 limited or
Modification.Wherein, srs-SubframeConfig configurations are limited, is in existing configuration, to use
Srs-SubframeConfig will not cause SRS to be sent in the subframe where above-mentioned DMTC.It is right
Srs-SubframeConfig configuration is modified, and is to use newly or utilize reserved
Srs-SubframeConfig, defines new Configuration Period and Transmission offset so that
SRS will not be sent in the subframe where above-mentioned DMTC.
And/or, to Table 8.2-1 and/or Table 8.2-2 and/or Table in 3GPP 36.213Rel-10~13
SRS Configuration Index Isrs configurations in 8.2-4 and/or Table 8.2-4 are limited or changed,
Avoid with DMTC configurations in identical subframe.
Configuration based on SRS, the send configuration to DMTC is limited and changed specially：Using not
Same DMTC offset, avoid that SRS subframe may be sent.
In one embodiment, it is described not send upward signal in DRS subframes and/or DMTC subframes
/ channel, including：
When upward signal/channel configuration is sent in DRS subframes and/or DMTC subframes, do not send on described
Row signal/channel.
Specifically, SRS is not sent in DRS subframes and/or DMTC subframes, the SRS includes trigger
Type 0 and trigger type 1 SRS；
Or, SRS is not sent in DRS subframes and/or DMTC subframes, the SRS includes trigger
Type 0 SRS.
In present embodiment, UE does not send SRS in the subframe where DRS and/or DMTC, including
Mode one：Flip-over type (trigger type) 0 and trigger type 1 SRS.Mode two：UE is in DRS
And/or SRS is not sent in the subframe where DMTC, include trigger type 0 SRS.
For mode one：SRS send configuration and parameter can not make an amendment, such as SRS sub-frame configuration
Configuration sequence number with SRS is constant, if SRS falls in the subframe where DRS and/or DMTC, is
The influence sent to DRS is avoided, UE does not send SRS.Because DMTC cycle is relatively long, most frequency
Numerous also to have 40ms, the flexibility ratio of SRS period assignments is larger, therefore in the subframe where DRS or DMTC
Lose (drop) and fall SRS influences less.
For mode two：Because trigger type 1 are by Downlink Control Information (DCI, Downlink Control
Information) the SRS types that triggering is sent, therefore can have higher priority, it is only necessary to which satisfaction is matched somebody with somebody
Put requirement and transmission condition such as channel idle, it is possible to sent in the subframe where DRS and/or DMTC.
But UE does not send trigger type 0 SRS in the subframe where DRS and/or DMTC.
It is described in one embodiment not sent in DRS subframes and/or DMTC subframes setting symbol
Row signal/channel, including：
Do not sent in last N number of OFDM symbol of DRS subframes and/or DMTC subframes upward signal/
Channel, N is positive integer.
Specifically, do not sent in last N number of OFDM symbol of DRS subframes and/or DMTC subframes
SRS, N are positive integer.
Here, transmission time-domain position of the upward signal/channel in the subframe is changed, to avoid the set symbol
Number.Specifically,
Can change SRS transmission time-frequency location, such as SRS the symbol 1 or 2 of subframe or 3,
Or sent or other symbols on 8.The subframe refers in particular to DRS subframes.This example limits UE at certain
Do not sent on a little special symbols, for example, last in special symbol subframe where DRS and/or DMTC
One symbol or most latter two symbol.Because the last symbol of subframe or most latter two symbol can be used for
DRS LBT/CCA。
