Description

A kind of ascending transmission method and equipment

Technical field

The present invention relates to the communications field, more particularly to a kind of ascending transmission method and equipment.

Background technology

With the surge of data traffic in mobile Internet, Long Term Evolution (Long Term are used in unauthorized frequency range Evolution, abbreviation LTE) technology turns into development trend.Unauthorized frequency range is for all wireless access technology (Radio Access Technologies, abbreviation RAT) and all operation commercial cities be open.In unauthorized frequency range, difference operation Business has the respective RAT systems of identical Rights Deployment, such as WIFI and unauthorized frequency range LTE.

Due to not doing interference coordination planning between the website of different RAT operator deployments, Bus stop planning (site is not such as Planning), therefore do not allow these website simultaneous transmission business, otherwise can cause stronger to interfere phenomenon.

In order that different RAT systems or with RAT systems different operator it is fair in order, do not compete with conflicting and use unauthorized frequency Section, that is, forbid simultaneous transmission business, introduce listem-before-talk (Listen Before Talk, abbreviation LBT) mechanism, i.e., each Before carrying out data transmission, reserved a period of time perceives to carrier wave, carries out clear channel assessment (CCA) (Clear Channel Assessment, abbreviation CCA) process, just carry out data transmission when perceiving carrier wave and can use, and carry out data transmission every time There is the limitation of maximum duration.

Therefore, when LTE system is operated in unauthorized frequency range, and evolved base station (Evolutional Node B, referred to as ENB) and user equipment (User Equipment, abbreviation UE) is also required to follow LBT mechanism.Especially, the UE's of LTE system is upper Row (UpLink, abbreviation UL) resource is all distributed in advance by eNB.Because unauthorized band channels competitive environment is complicated and changeable, It is that can not predict UE in advance whether can be scheduled when UL scheduling resource information is sent to UE by eNB (such as at subframe n) Channel access chance is arrived in moment (such as at subframe n+k) competition.If UE fails at subframe n+k, competition connects to channel Enter chance, then the UL resource scheduling informations sent at subframe n will be cancelled because of failure.

Referring to Fig. 1, for the schematic diagram of UL scheduling Problem of Failure.As shown in (b) in Fig. 1, eNB is at the n-th-k (for example, k =4) UE1 and UE2 are dispatched since n-th of subframe by UL grant signalings respectively in subframe, carried out in M continuous subframes UL is transmitted, and UE1 and UE2 frequency division multiplexing UL bandwidth.UE1 and UE2 performs UL LBT operations to compete letter at (n-1)th subframe Road accesses chance.If UL LBT are operated successfully, the UE is allowed to carry out UL transmission in M scheduled continuous subframes；It is no Then, the UE abandons current UL transmission opportunitys, and UL transmission is carried out not in this M continuous subframes, and in M continuous subframes not UL LBT operations are performed again.As shown in (a) in Fig. 1, UE1 nearby has individual WIFI interference sources, and the WIFI interference sources are UE1's In the range of CCA is intercepted, and intercepted in eNB and UE2 CCA outside scope.The WIFI interference sources are in the n-th-m subframes to n-th Transmitted in subframe.

Because the WIFI interference sources are intercepted outside scope in UE2 CCA, therefore the existence of the WIFI interference sources will not block UE2 LBT behaviors, thus UE2 in (n-1)th subframe can successful contention to channel access chance, and then from n-th son Frame starts, and UL transmission is continuously carried out in M subframe.However, for UE1, because CCA of the WIFI interference sources in UE1 is detectd In the range of listening, therefore UE1 LBT operations can be blocked, cause UE1 can not compete channel access chance in (n-1)th subframe.Cause This UE1 will abandon current UL transmission opportunitys, and UL transmission is carried out not in this M continuous subframes.Because eNB reserves for UE1 in advance UL resources, if UE1 transmits without UL, then the UL resources are just wasted.

As can be seen here, because UE UL LBT operations are easily blocked by neighbouring interference source, may result in than more serious The UL wastings of resources phenomenon.

Embodiment

In order that the object, technical solutions and advantages of the present invention are clearer, the present invention is made below in conjunction with accompanying drawing into One step it is described in detail, it is clear that the described embodiment only a part of embodiment of the present invention, rather than whole implementation Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made All other embodiment, belongs to the scope of protection of the invention.

Base station in the embodiment of the present invention, can be that evolved base station, macro base station, the micro-base station in LTE system (are also referred to as " small base station "), femto base station, access website (Access Point, referred to as AP) or transmission website (Transmission Point, referred to as TP) etc., the present invention is not limited this.

Terminal in the embodiment of the present invention, including various forms of user equipmenies, mobile station (Mobile station, letter Claim MS), terminal (terminal), terminal device (Terminal Equipment) etc., the present invention is not limited this.

For convenience of description, following embodiments will illustrate by taking base station and terminal as an example.

It is schematic flow sheet of the ascending transmission method provided in an embodiment of the present invention in base station side referring to Fig. 2.As schemed Show, this method comprises the following steps：

Step 201, base station are directed to first terminal, it is determined that the second terminal of the ascending resource for being multiplexed first terminal.

Base station is that first terminal determines a second terminal, so that second terminal and the first terminal multiplexing up money of identical Source, to avoid ascending resource from wasting.Wherein, first terminal is to be made a distinction with other-end with second terminal, is not spy Refer to some or certain terminal.

Specifically, base station can be that first terminal builds an end candidate terminal list, be selected from the candidate terminal list Select second terminal.

In certain embodiments, base station, can be to using the base station as serving BS when building the candidate terminal list Terminal, according to the candidate terminal determined with the distance between first terminal for being multiplexed first terminal ascending resource.For example, base station Can to being estimated by the distance between other-end and first terminal of serving BS of the base station, will with first terminal away from It is added to from K terminal farther out in the candidate terminal list of first terminal, wherein, K is the integer more than or equal to 1；Or will It is more than the terminal of default distance threshold with the distance of first terminal, is added in candidate terminal list.If answered with first terminal It is directly closer to the distance with the second terminal and first terminal of ascending resource, then when first terminal is interfered the interference in source, Second terminal be able to may also be interfered, and cause ascending resource to be wasted, and therefore, will be selected with the distant terminal of first terminal For the candidate terminal of first terminal, the utilization rate of ascending resource can be improved.

In further embodiments, base station can also be scheduled when building the candidate terminal list according to first terminal Frequency domain resource determine candidate terminal.For example, on the frequency domain that will be scheduled in first terminal, signal to noise ratio is more than the end of predetermined threshold value End, i.e., the terminal of higher channel quality can be obtained on the frequency domain that first terminal is scheduled, is added to candidate terminal list In.If more matched with the working frequency range of first terminal with the second terminal of first terminal multiplexing ascending resource, when the first end When end is interfered, second terminal carries out uplink on the ascending resource of first terminal, can obtain preferable channel matter Amount, the utilization ratio of ascending resource can be improved.

In further embodiments, base station can also be according to the work with the distance between first terminal and first terminal Frequency range, it is determined that the second terminal for being multiplexed first terminal ascending resource.It can either reduce second when first terminal is interfered The possibility that terminal is also interfered, and can enough ensure second terminal when carrying out uplink on the ascending resource of first terminal With higher channel quality.

Specifically, base station can in the following manner to first terminal and using the base station as serving BS other-end it Between distance estimated：

Mode one：Based on base station measurement

Base station measures to the antenna direction angle of arrival and path loss information using the base station as the terminal of serving BS, Statistics.Wherein, path loss information is included based on base station side antenna transmission power in downlink and end side antenna receiving power Difference, or difference based on antenna transmission power in end side in up-link and base station side antenna receiving power etc..Base station root According to the antenna direction angle of arrival and path loss information of terminal, the position of terminal is estimated, then further estimation first is whole The distance between end and other-end.

Mode two：Measured based on first terminal

Base station indicates that the signal power that first terminal is sent to the other-end using the base station as serving BS measures And feed back to base station.Specifically, base station can by DCI signalings or RRC signaling, by the up transmission signal of other-end when Frequency position, the configured information (scramble information be DMRS cyclic shift and OCC) of scramble information, the sequence of SRS reference signals and One or more in the information such as time-frequency location, uplink transmission power are sent to first terminal, and first terminal is according to receiving Information, the receiving power of signal sent to other-end measure, and by measurement feedback to base station, and base station is according to the The measurement result of one terminal feedback is estimated the distance between first terminal and other-end.Or base station is except will be upper The one or more stated in information are sent to first terminal, default receiving power thresholding can also be sent into first terminal, First terminal by the other-end measured send signal receiving power with default receiving power thresholding compared with, and general Comparative result feeds back to base station；For example, if the signal power that receiving terminal A is sent is less than default receiving power thresholding, say Bright terminal A and first terminal are distant, conversely, explanation terminal A and first terminal it is closer to the distance.

Step 202, base station send configured information to second terminal.

The configured information is used to indicate second terminal in the case where meeting preparatory condition, in the ascending resource of first terminal Surplus resources on carry out uplink.Wherein, preparatory condition comprises at least：First terminal is not carried out on the ascending resource Row transmission.

For example, above-mentioned preparatory condition may include following several situations：

Situation 1：First terminal does not carry out uplink on the ascending resource.

Second terminal and first terminal multiplexing identical ascending resource, if first terminal carried out on the ascending resource it is up Transmission, then second terminal does not carry out uplink on the ascending resource, otherwise, on second terminal is carried out on the ascending resource Row transmission.

Situation 2：First terminal does not carry out uplink on the ascending resource, and in time domain corresponding to the ascending resource On, exist for the other-end using above-mentioned base station as serving BS and carry out uplink.

Wherein, the allocated ascending resource of above-mentioned other-end it is identical with the time domain of the ascending resource of first terminal, in phase In same frequency range.

If carry out up biography the other-end using the base station as serving BS corresponding to the ascending resource in time domain be present Defeated, then it is considered that the ascending resource is available for terminal, i.e., second terminal can be carried out on the ascending resource Row transmission；Otherwise, it is believed that the ascending resource is disabled to terminal, i.e., second terminal is not carried out on the ascending resource Uplink.If for example, channel by using the base station as outside the other-end of serving BS other access nodes (for example, WiFi system, or the base station of other operators or terminal) to seize, then the ascending resource is to the terminal and using the base station as service base The other-end stood all is disabled, therefore carries out uplink currently without other-end, and second terminal is in the up money Detected corresponding to source in time domain and carry out uplink in the absence of other-end, then second terminal is also without uplink；If Second terminal detects the presence of other-end and carries out uplink, then it is believed that the ascending resource is available to terminal.

Situation 3, first terminal does not carry out uplink on the ascending resource, and second terminal is inscribed in the ascending resource The interference signal intensity received is not less than default threshold value.

If the interference signal intensity received in the second terminal ascending resource exceedes default threshold value, it is believed that second Terminal carries out uplink on the ascending resource will not have higher channel quality, and therefore, second terminal can be abandoned Uplink is carried out on the ascending resource.

Situation 4, first terminal do not carry out uplink on the ascending resource, exist corresponding to the ascending resource in time domain Other-end using above-mentioned base station as serving BS carries out uplink, and second terminal received in the ascending resource it is dry Signal intensity is disturbed not less than default threshold value.

, can be with as it was previously stated, ascending resource can not only be avoided to waste if preparatory condition is configured according to situation 4 Ensure preferable demodulation performance.

Alternatively, base station can indicate that the terminal of the base station sends up common reference letter when carrying out uplink in advance Number.Second terminal can be judged corresponding to first terminal ascending resource according to the reception condition of the up public reference signal It whether there is the other-end using above-mentioned base station as serving BS in time domain and carry out uplink.Specifically, if second terminal connects The up public reference signal that the other-end using above-mentioned base station as serving BS is sent is received, then explanation has other-end Uplink is carried out, otherwise it is assumed that carrying out uplink in the absence of other-end.

Specifically, the configuration information of the up public reference signal, such as the time-frequency location of the up public reference signal Information, reference signal sequence etc., terminal can be sent in advance by base station or be made an appointment by standard agreement, The present invention is without limitation.

Specifically, identity (Identification, the abbreviation of cell can be included in the up public reference signal ID) information.The up public reference signal sends density and could be arranged to uplink transmission block rank, i.e., in an ascending resource Comprising M continuous subframes in send once the up public reference signal, it can also be provided that sub-frame level is other, i.e., upper The up public reference signal is sent in each subframe of row resource, wherein M is the integer more than or equal to 2.

Specifically, the frequency patterns of the up public reference signal and sequence may be referred to detection reference signal (Sounding Reference Signal, abbreviation SRS), that is, a kind of special SRS signal structure is defined as up public ginseng Examine signal.Sequence (depending on cyclic shift parameter in SRS), the frequency patterns of the special SRS signal (depend in SRS matching somebody with somebody Put parameter) all it is identical to terminal all in all same cells.Base station can pass through Downlink Control Information (Downlink Control Information, abbreviation DCI) or wireless heterogeneous networks (Radio Resource Control, Abbreviation RRC) signaling or system message, above-mentioned special SRS notices are given into the terminal that the base station is serving BS, or, It can be made an appointment by standard agreement.

Alternatively, the configured information that base station is sent to second terminal in above-mentioned steps 202 can be base station to second terminal The UL grant DCI signalings of transmission.The instruction letter of the ascending resource of first terminal can be included in the UL grant DCI signalings Breath, and the configured information of the scramble information of first terminal, wherein, the ascending resource of first terminal can include M continuously Sub-frame of uplink, scramble information include following for demodulated reference signal (Demodulation Reference Signal, abbreviation DMRS) Ring shifts and orthogonal convolutional code (Orthogonal Convolutional Code, abbreviation OCC), and the scramble information is used to scramble The DMRS of first terminal transmission.Second terminal can be examined after the configured information is received on the ascending resource of first terminal Survey with the presence or absence of the up DMRS scrambled by first terminal scramble information, if detecting, illustrate first terminal in the up money Uplink is carried out on source, otherwise it is assumed that first terminal does not carry out uplink on the ascending resource.

Alternatively, the configured information can also be the DCI signalings or RRC signaling that base station is sent to second terminal, as finger Show in the DCI signalings or RRC signaling of information, the Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell of first terminal can be included Radio Network Temporary Identifier, abbreviation C-RNTI).Second terminal after the configured information is received, It can monitor by the upstream dispatching instructions of the C-RNTI scramblings of first terminal, and therefrom be retrieved as the up money of first terminal distribution The configured information of the configured information in source and the scramble information of first terminal.Second terminal, can after the configured information is received On the ascending resource of first terminal, to detect whether to have the up DMRS scrambled by first terminal scramble information, if detection Arrive, then illustrate that first terminal has carried out uplink on the ascending resource, otherwise it is assumed that first terminal is not in the ascending resource Upper carry out uplink.

In above two alternatively implementation, if base station is by the instruction of the ascending resource of first terminal and scramble information Information is transmitted directly to second terminal, can reduce the complexity of the processing procedure of second terminal, but increases the signaling of base station Expense；If the C-RNTI of first terminal is sent to second terminal by base station, reduce the signaling consumption of base station, but add second The complexity of the processing procedure of terminal.Therefore, in actual applications, different realization sides can be selected according to specific application scenarios Formula.

If second terminal, which detects, meets preparatory condition, second terminal carries out uplink on the ascending resource.The Two terminals use the DMRS of the scramble information scrambling second terminal transmission of second terminal when carrying out uplink.
