Description

The transmission method and device of uplink feedback information

Technical field

The present invention relates to the communications field, in particular to the transmission method and device of a kind of uplink feedback information.

Background technology

In the related art, the communication network of Long Term Evolution (Long Term Evolution, referred to as LTE) is all portion The operation that worked on carrier wave is authorized is affixed one's name to, with LTE development, some companies are proposed " it is recommended that research LTE is deployed in non-award Weigh the problem in carrier wave ", the Qualcomm in such as U.S. thinks：With the rapid growth of data service, in the near future, award The huge data volume that fastext growth is brought will can not be born by weighing the resource of carrier wave.Consider by being disposed on unauthorized carrier wave LTE serving cells, the data traffic authorized in carrier wave is shared with this, can be solved business and be increased the data volume pressure brought； Here it is normal structure is for third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) The enhancing auxiliary studied and defined authorizes access (Enhanced Licensed Assisted Access, referred to as (e) LAA) technology.

Unauthorized carrier wave has the characteristics that：On the one hand, because unauthorized carrier wave does not need operator to go competitive bidding to buy, Huo Zhezai Ripple resource is zero cost, thus unauthorized carrier wave can free or low expense be utilized；On the other hand, due to personal, enterprise also all The deployment of related network device can be participated in, therefore the entry criteria of unauthorized carrier wave requires low；Furthermore, unauthorized carrier wave has Fairshare, operation is shared wherein by multiple different systems systems, or the different operators of same standard system are shared When operation wherein, the utilization ratio of carrier resource can be improved.

In summary, although LTE technologies, which are deployed on unauthorized carrier wave, has obvious commercial advantage, still, in deployment operation During, still there is problem；Wherein, wireless access technology species is more (across the communication standard of different systems, radio node Between cooperate difficult, network topology is various) and wireless access website it is many (number of users is big, the difficulty that cooperates greatly, centralized management expense Greatly), therefore, it is deployed in for LTE on unauthorized carrier wave, it is necessary to support the regulations that unauthorized carrier wave is used.Majority state It is required that, it is necessary to support listem-before-talk (Listen before talk, referred to as LBT) when any communication system is disposed on unauthorized carrier wave Fundamental mechanism.It can be avoided by listem-before-talk between adjacent wireless system while using local unauthorized carrier resource The interference and conflict brought each other.And in order to further reduce the probability of conflict interference, random competition fallback mechanism is introduced, I.e. neighbouring system website (being usually the neighbouring transmission node of same system), same tie can be avoided by competing after fallback mechanism The neighbouring transmission node of system is while the interference brought during using unauthorized carrier wave.Control is provided：It is any to use unauthorized carrier resource Equipment (including LTE base station and user equipment (User Equipment, referred to as UE)) be required for before transmitting carry out LBT operates (i.e. clear channel assessment (CCA) (Clear Channel Assessment, CCA)), and when the channel is idle, equipment can just make The data that a period of time is carried out with unauthorized carrier channel are sent.Such as eNB successfully passes LBT operations, robs and accounts for some and non-award Carrier channel is weighed, can just be sent with downlink data, and UE successfully passes LBT operations, robs and accounts for some unauthorized carrier channel, It can just be sent with up.Here the content sent both can be user service data block or control information etc..

In LTE system, UE, which needs that the relevant data block that eNB downlink datas are sent receive successfully feedback whether, to be answered (acknowledgeme, referred to as ACK)/non-response (Negative Acknowledgeme, referred to as NACK) is answered, and Also need to feed back the channel condition information (Channel State Information, referred to as CSI) in the past period, to aid in ENB carry out Future Data scheduling (weight) transmission, the above-mentioned up transmissions of UE ascending control information (Uplink Control Info, Referred to as UCI), it correspond to one or more descending sub frame.UCI can both pass through ascending physical signal shared channel (Physical Uplink shared channel, referred to as PUSCH), Physical Uplink Control Channel (Physical Uplink Control can also be passed through Channel, referred to as PUCCH) carry out uplink.For example, base station is sent in the corresponding PDSCH channels of descending sub frame n Downlink data block, UE needs the spy in the corresponding PUSCH channels of sub-frame of uplink n+4 or PUCCH channels after receiving parsing Determine to send UCI information on Physical Resource Block to base station.

In LTE, UE sends the corresponding downlink data block that the sub-frame of uplink position of UCI feedbacks is sent with base station in a synchronous manner Subframe position remain the sub-frame interval relation of agreement, for example, frequency division duplex mode (Frequency Division Duplex, Referred to as FDD) under be n+4 fixation sub-frame interval relation (each subframe durations of LTE are 1ms)；Time division duplex (Time Division Duplex, referred to as TDD) under need according to the configuration of TDD specific ascending-descending subframes, according to the table of standardization N+x agreement sub-frame interval relation can be determined.The sub-frame interval relation of above-mentioned fixation is to be easy to ensure for authorizing on carrier wave Realize, can arranged by eNB scheduling controlling, eNB and UE completely because authorizing the up-downgoing channel resource of carrier wave Subframe position ensure to send relevant information, Fig. 1 is according to LTE FDD systems descending scheduling transmission in correlation technique and up anti- In the schematic diagram of feedback, such as Fig. 1, receive to UE, UE when base station sends downlink data block in subframe n and be resolved to the data block Afterwards, it is necessary in the subframe n+4 of agreement up transmission UCI feedback informations.But above-mentioned UCI feedback operations are for unauthorized The problem of carrier wave will have following：Fig. 2 is the signal according to LAA system descendings scheduled transmission and uplink feedback in correlation technique In figure, such as Fig. 1, receive and be resolved to after the data block to UE, UE when base station sends downlink data block in subframe n, The up transmission UCI information in subframe n+4 is needed, but before subframe n+4 arrival, due to the pipe of LBT on unauthorized carrier wave Demand processed, UE needs to first carry out LBT operations i.e. CCA detections, and when detecting, the unauthorized carrier channel is idle (to detect channel Middle energy is less than pre-determined threshold) when, UE could use subframe n+4 to send UCI, when being detected as busy (busy), UE Subframe n+4 cannot be used to send UCI.Then when the latter occurs, UE is by can not be in the subframe position arranged with base station UCI feedback informations are sent, eNB can not know that the downlink data of data block in subframe n sends situation and the past period CSI Metrical information, it is impossible to further accurate downlink data dispatching.

For on unauthorized carrier wave, the problem of up auxiliary informations of UCI may not be sent in time due to LBT operation failures, PUSCH or PUCCH channels auxiliary that can be on mandate carrier wave is sent, but this can only authorize auxiliary access to same base station (Licensed Assisted Access, referred to as LAA) operation is applicable, because the auxiliary services of LAA now on unauthorized carrier wave Serving cell colocation site and common scheduler in cell (Scells) and mandate carrier wave, master base station (MeNB) is from mandate carrier wave The uplink feedback UCI received, downlink data block is sent on unauthorized carrier wave situation and CSI feelings can be recognized rapidly Condition.But for different base station LAA dual links operation (LAA-DC) operation, because prothetic group station (LAA-SeNB) can not lead to Cross mandate carrier wave and obtain UCI auxiliary informations in good time, so as to have influence on mandate auxiliary access auxiliary region group (Licensed Assisted Access secondary Cell Group, referred to as LAA-SCG) side downlink data transmission performance.

With reference to preferred embodiment and embodiment, the present invention is described in detail.

When LTE system is operated on unauthorized carrier wave, there is downlink data block transmission, due to LBT control requirement, UE Up UCI feedback of the information possibly can not be sent out on current predetermined n+4 subframe positions (or other subframe positions of system agreement) Send, so as to cause base station can not receive UCI feedbacks in good time, this is for the LAA-SeNB bases under LAA-DC operations Influence of standing is especially serious.UCI is introduced by the preferred embodiments of the present invention and feeds back enhancing mechanism, can cause LAA-SeNB bases UCI information can be timely received in n+4 subframe positions (or other subframe positions of system agreement) by standing, so as to improve Downlink data transmission efficiency of the LTE system on unauthorized carrier wave.

X2 interface delay between connection LAA-MeNB and LAA-SeNB<Under 4ms scene, Fig. 7 is according to this hair The schematic diagram of the up assistance information transmission mode 1 of LAA-SeNB sides, such as Fig. 7 in the LAA-DC systems of bright preferred embodiment Shown, the embodiment of the preferred embodiment includes：

For certain downlink data block on the unauthorized carrier wave in LAA-SCG sides, network side is allocated to UE in LAA-MCG sides Certain authorize some UCI on carrier wave to send subframe position information, or up candidate's subframes interval information.The up candidate's subframes and Corresponding downlink data block sub-frame interval is less than 4ms and agreement of other early stages interval.

UE allows the preferential data block to being issued from the unauthorized carrier wave in LAA-SCG sides to carry out reception parsing, produces corresponding UCI As a result, UCI information is then sent on the up candidate's subframes position that network side is configured.

UE can be in some up candidate's subframes, while multiple downlink data blocks are done with UCI joint feedback, i.e., identical subframe Interior UCI information had both contained data block to being issued before from the unauthorized carrier wave in LAA-SCG sides and other from network side The joint feedback of the data block issued on carrier wave is authorized, and one section of channel receives the CSI metrical informations in observation time in the past.

Network side LAA-MeNB attempts to receive UCI auxiliary informations on the up candidate's subframes position；Network side needs energy The number for confirming from the UCI united informations received and extracting and being issued before from the unauthorized carrier wave in LAA-SCG sides According to the corresponding part UCI information of block.

By part UCI information corresponding with the data block issued on the unauthorized carrier wave in LAA-SCG sides after LAA-MeNB, LAA-SeNB is quickly passed to by X2 interface so that LAA-SeNB can current predetermined n+4 subframe positions (or System agreement other subframe positions) on receive UCI information corresponding with oneself downlink data block.So from LAA-SeNB From the point of view of, direct eating dishes without rice or wine from LAA-SCG is equivalent to, in predetermined n+4 subframe positions (or other subframes of system agreement Position) on receive UCI information corresponding with oneself downlink data block.

UCI sends subframe position information, or up candidate's subframes interval information be the up UCI auxiliary informations of description with it is corresponding non- Authorize the time dimension interval between the downlink data block on carrier wave.Wherein, time dimension interval can be by the number of sub frames at interval Measure to describe, such as the sub-frame number at the time dimension interval of current FDD system acquiescence agreement is 4, in the present invention, the value Candidate value under 4, such as LTE FDD systems should be less than：1,2,3.

Network side can be that UE configures above-mentioned time dimension interval by UE special RRC messages or system broadcasts RRC information Information.Configuration Values depend on connection LAA-MeNB and LAA-SeNB between X2 delay, it is ensured that X2 delay+it is above-mentioned when Between the dimension intervals=4ms other subframe positions of agreement (or system).

Because UE is in same subframe position, multiple downlink data blocks may be received from the carrier wave of multiple polymerizations simultaneously, due to UE base band processing capacities are limited, therefore preferential as early as possible the data block reception solution issued from the unauthorized carrier wave in LAA-SCG sides Analysis, produces UCI results ahead of time；If the UCI subframe position moment that UE can not be configured in network side produces UCI, abandon UCI is sent in the UCI subframe positions.

Due to being limited by channel resource capacity in PUSCH and PUCCH single sub-frames, the united feedback informations of UCI can not nothing What is limited is cumulatively added, therefore when more than subframe capacity limit, in preferential carrying feedback and the unauthorized carrier wave in LAA-SCG sides The corresponding UCI information of data block issued.

Network side LAA-MeNB can pass through physical layer control on the time dimension interval basis that RRC high-level signalings are configured Information inference processed goes out part UCI information corresponding with the data block issued on the unauthorized carrier wave in LAA-SCG sides, i.e., which UCI information also needs to further be delivered to LAA-SeNB by X2 interface.

LAA-MeNB is by X2 dedicated bearings handle correlation UCI information transmissions to LAA-SeNB, it is necessary to ensure that UCI is arrived at LAA-SeNB sequential just meets in terms of LAA-SeNB angles predetermined n+4 subframe positions, and (or system agreement is other Subframe position).LAA-SeNB is required to derive which the UCI information received from LAA-MeNB corresponds to The data block issued on the unauthorized carrier wave in LAA-SCG sides.

If LAA-SeNB can not receive corresponding UCI information in predetermined subframe position, informed by the proprietary message of X2 LAA-MeNB receives the situation of UCI step-outs, and subsequent LAA-MeNB futures need adjustment UCI transmission sequential.

It is delayed towards the X2 interface between connection LAA-MeNB and LAA-SeNB>4ms (or system agreement is other Subframe position) scene under, Fig. 8 is the up of LAA-SeNB sides in LAA-DC systems according to the preferred embodiment of the invention The schematic diagram of assistance information transmission mode 2, as shown in figure 8, the embodiment of the embodiment includes：

Due to the delay of X2 interface>The 4ms other subframe positions of agreement (or system), therefore mode 1 can not be applicable, in order to Remaining able to maintain the downlink data block transmission of LAA-SeNB sides and uplink feedback n+4 subframe positions, (or system agreement is other Subframe position) relativeness, the up LBT in the LAA-SCG sides probability of success can only be increased, can there is two kinds of basic skills： 1：The region of SCS mechanism is not being supported, network side is that UE configures high CCA detection threshold CCA-ED TL, that is, is existed Under the local medium and small interference strengths of UE, can be operated with the higher probability of success by quick LBT, thus n+4 subframe positions (or Other subframe positions of person's system agreement), the uplink UCI information on the unauthorized carrier wave that LAA-SCG sides are configured.2： The region of SCS mechanism is being supported, original 1ms durations are compressed into by UE containing UCI sub-frame of uplink meets the applicable bars of SCS The shorter and smaller control signal frame that part and system are supported, the so region in some support SCS mechanism, can not perform LBT operations It is up directly on the unauthorized carrier wave that LAA-SCG sides are configured directly to transmit UCI information.

Network side can configure the high CCA inspections that special service uploads purpose in UCI signals by UE special RRC messages Survey thresholding, CCA detection threshold value of the threshold value apparently higher than other transmission purposes.

New short frame mechanism that UE is introduced according to LTE evolution systems subsequent normalization (such as new subframe lengths are 0.5ms, 0.1ms, 1OFDM Sysbol etc.) UCI information is carried, by new short frame+SCS mechanism, without performing LBT operations directly up hair Send UCI information.
