Description

Transmit the method, apparatus and system of data Technical field

The present embodiments relate to the communication technology more particularly to a kind of method, apparatus and system for transmitting data.

Background technique

Frequency spectrum resource is the basis of wireless communication.According to the international spectrum white paper of Federal Communications Commission (Federal Communications Commission, referred to as: FCC) newest publication, unauthorized (unlicensed) frequency spectrum resource will be more than authorization frequency spectrum resource.Due to not constraining on unlicensed spectrum the use of wireless communication system and operator at present, there are plurality of communication systems, multiple operation commercial cities to want the case where occupying same channel.According to the current regulation of ETSI EN 301893, wireless telecom equipment needs to follow European Telecommunications Standards Institute (European Telecommunications Standards Institute when using on unlicensed spectrum, listem-before-talk (Listen Before Talk, referred to as: LBT) rule referred to as: ETSI) in 301 893 standard of ETSI EN issued.For LBT rule, that is, wireless telecom equipment before using unlicensed spectrum, whether the channel for first listening to unlicensed spectrum is idle, and the channel transmission data of the unlicensed spectrum can be used if channel idle.Wireless telecom equipment can execute channel idle assessment (Clear Channel Assessment, referred to as: CCA) by energy measuring.

Long term evolution (Long Term Evolution, from base station (Evolved Node B referred to as: LTE) in system, referred to as: eNodeB) to user equipment (User Equipment, referred to as: UE) link sent is known as downlink, is known as uplink from UE to the link that eNodeB is sent.The data that eNodeB is sent to UE pass through Physical Downlink Shared Channel (physical downlink shared channel in physical layer, referred to as: PDSCH) carry, the data that UE is sent to eNodeB pass through Physical Uplink Shared Channel (physical uplink shared channel, referred to as: PUSCH) carrying in physical layer.ENodeB passes through Physical Downlink Control Channel (physical downlink control channel, referred to as: PDCCH) or the Physical Downlink Control Channel (enhanced physical downlink control channel, referred to as: ePDCCH) of enhancing used on PDSCH and/or frequency spectrum resource from PUSCH to UE instruction, transmission mode.As it can be seen that frequency spectrum resource used in any uplink of UE is allocated in advance by eNodeB.

But using unlicensed spectrum as when the operation frequency spectrum of LTE system, eNodeB can not " foresighted " in the chance that the expected moment sends upstream data for whether UE can be obtained by monitoring the channel of unlicensed spectrum.The channel that UE judges whether can to occupy unlicensed spectrum send data depend on its to channel of unlicensed spectrum whether Kong Xian testing result, in the case where only determining that the channel of unlicensed spectrum is the free time, can just occupy channel transmission data.When from detection initial time, the assessment after the default assessment time then needs to be implemented the detection of " extending CCA " to the channel transmission data that cannot occupy unlicensed spectrum to UE, the detection time length for extending CCA is N times of a CCA time span.If eNodeB has done uplink scheduling to UE on unlicensed spectrum, it is expected that UE sends upstream data using pre-assigned frequency spectrum resource in subframe n, but UE is practical when subframe n sends upstream data, detects that resource is occupied and expected operation can not be completed according to the instruction of eNodeB.In this way, eNodeB just becomes an invalid resource distribution for the uplink scheduling of UE, and eNodeB can't distribute to other UE to the resource for being already allocated to UE simultaneously, and the UE cannot indicate to send upstream data according to scheduling due to not having occupancy upper signal channel, it causes to have distributed the waste of frequency spectrum resource, is reduced so as to cause the efficiency of transmission of communication system.

Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, following will be combined with the drawings in the embodiments of the present invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.

Fig. 1 is the flow chart of one embodiment of the method for present invention transmission data, as shown in Figure 1, the method for the present embodiment may include:

Step 101, the first equipment, which determine, assesses the initial time whether shared channel is in idle condition；

The first equipment in the present invention can be UE, is based on unlicensed spectrum with the second equipment eNodeB and is communicated, unlicensed spectrum is the shared channel.Optionally, macro base station (Macro eNodeB) and micro-base station (Pico eNodeB) in communication system can also be used as the first equipment and the second equipment in the present invention, and macro base station and micro-base station can act alternately as the first equipment and the second equipment.Optionally, the first equipment or the second equipment be can serve as using the equipment of shared channel communication in communication system.The first equipment will be communicated by shared channel in the present embodiment, need first share whether channel is idle using LBT rule detection, and the shared channel of only idle state, which is only, can occupy and be communicated.First equipment determines whether Kong Xian principle is shared channel: if since the first equipment assessing the initial time of idle state of shared channel, to the finish time of default assessment time, it detects shared channel idle, then can determine whether that shared channel is idle state and occupies the shared channel transmission data；If since the first equipment assessing the initial time of idle state of shared channel, to the finish time of default assessment time, detect that shared channel is occupied, the shared channel cannot currently be occupied by, which then judging, sends data, at this time, whether the first equipment needs to continue to assess shared channel idle since the finish time of default assessment time.On the other hand, it is pre-assigned by eNodeB that UE, which sends the resource that data use, the frequency range of the resource and time are all determining, if UE in the idle state that use the resource just to begin the evaluation at shared channel when sending data, probably can not indicate to send data according to scheduling using the resource in the determining time since shared channel is occupied in this way.

The probability of the idle state of shared channel is detected to improve the first equipment on determining time and frequency resource, and the shared channel is occupied in time and sends data, the first equipment determines first in the present embodiment assesses the initial time whether shared channel is in idle condition, and the initial time can be according to first The temporal information that the shared channel that equipment is got may be released determines that the first time after shared channel can be released by such first equipment is determined as assessing the initial time whether shared channel is in idle condition；The temporal information that the initial time can also be got according to the first equipment itself will transmit data determines that some moment before the time that will transmit data can be determined as assessing the initial time whether shared channel is in idle condition by such first equipment.

Step 102, first equipment assess whether the shared channel is in idle condition within the default assessment time since the initial time；

First equipment determines itself from when beginning the evaluation at whether shared channel is in idle condition, and start to be assessed when reaching the time, first equipment is sustainable within the default assessment time to detect whether shared channel is in idle condition, as long as the state for during this period of time sharing channel is idle always, it can determine that shared channel is idle state, and occupy the shared channel transmission data.The default assessment time can be by preconfigured one on the middle and senior level fixed duration of communication system, it is also possible to one that the first equipment and the second equipment are arranged in advance before communicating fixed duration, the first equipment and the second equipment approve that needs determine whether shared channel is in idle condition in the duration.Begin to assess whether shared channel is in idle condition since the first equipment is released in shared channel one, or before it will transmit the time of data, begin the evaluation at whether shared channel is in idle condition in advance, such first equipment detects a possibility that shared channel is in idle condition with regard to big within the default assessment time, and the first equipment once occupies shared channel to use pre-assigned resource transmission data in expeced time.

Step 103, first equipment determine whether according to the assessment result whether shared channel is in idle condition is assessed in the shared channel data.

It has been assessed whether shared channel is in idle condition according to first equipment of step 102, therefore according to assessment result, the first equipment can then determine whether can be in shared letter to transmitting data.

The present embodiment, first equipment is by determining the initial time assessing shared channel and whether being in idle condition, it improves the first equipment and detects the probability that shared channel is in idle condition within the default assessment time, the first equipment is set effectively to occupy shared channel and in the shared channel data, the waste for avoiding allocating in advance resource improves the efficiency of transmission of communication system.

Optionally, before 101 first equipment of above-mentioned steps determines and assesses the initial time whether shared channel is in idle condition, received the method also includes: first equipment in the broadcast message, scheduling instruction information, scheduling restricted information that the second equipment sends at least one of information.

Specifically, the first equipment can pass through the broadcast message that receives, scheduling instruction information, scheduling At least one information in restricted information, which determines, assesses the initial time whether shared channel is in idle condition.

Optionally, the broadcast message includes the temporal information that the shared channel is released；First equipment described in above-mentioned steps 101, which determines, assesses the initial time whether shared channel is in idle condition, and concrete implementation method may is that the initial time that the time that the temporal information instruction that channel is released is shared described in the broadcast message is determined as assessing whether the shared channel is in idle condition by first equipment.

Specifically, the temporal information that the shared channel for including in the broadcast message that second equipment is sent is released can be the temporal information that the second equipment itself discharges shared channel, be also possible to non-first equipment in communication system, the other equipment of the second equipment discharge the temporal information for sharing channel.Second equipment broadcasts out the temporal information that shared channel is released by broadcast message, after first equipment receives the broadcast message, so that it may which will share the time indicated by the temporal information that is released of channel in the broadcast message is determined as assessing the initial time whether shared channel is in idle condition.

Optionally, the scheduling instruction information includes the resource scheduling information for the transmission upstream data that second equipment is first equipment distribution；First equipment described in above-mentioned steps 101, which determines, assesses the initial time whether shared channel is in idle condition, concrete implementation method may is that first equipment according to the sequential relationship between the time of the time for the resource scheduling indication information for receiving upstream data upstream data corresponding with transmission indicated by the scheduling instruction information of the upstream data, determine the time for sending corresponding upstream data, and it will be determined as assessing the initial time whether shared channel is in idle condition than the time for presetting the assessment time described in the time advance for sending corresponding upstream data.

Specifically, the second equipment can indicate to transmit frequency spectrum resource, the transmission mode that data use on a shared channel to the first equipment by PDCCH or ePDCCH, this is the resource scheduling information for the transmission upstream data that the second equipment is sent to the first equipment.Sequential relationship between the time of the corresponding upstream data of transmission according to indicated by the resource scheduling information of upstream data in communication system and the scheduling information of the upstream data, first equipment is exactly its time for sending using running time-frequency resource corresponding upstream data every a period of time (for example, 4 subframes in LTE) after the resource allocation scheduling information for receiving the upstream data.Therefore the time of assessment time more default than the time advance for sending corresponding upstream data can be determined as assessing the initial time whether shared channel is in idle condition by the first equipment.Since the first equipment has evaluated whether shared channel is in idle condition before the time for sending corresponding upstream data in advance, improves the first equipment and occupy the probability for sharing channel in the time for sending corresponding upstream data.

Optionally, the scheduling instruction information includes the scheduling letter that second equipment sends downlink data Breath；First equipment described in above-mentioned steps 101, which determines, assesses the initial time whether shared channel is in idle condition, and concrete implementation method may is that the time that the shared channel of scheduling information instruction of first equipment by the downlink data is released is determined as assessing the initial time whether shared channel is in idle condition.

Specifically, it include the scheduling information of downlink data in the downlink data that second equipment is sent to the first equipment, the scheduling information is specially to be sent to the first equipment, rather than above-mentioned broadcast message can be received by multiple communication equipments, the time being also released comprising shared channel in the scheduling information, after first equipment gets the scheduling information of the downlink data, so that it may be determined as assessing the initial time whether shared channel is in idle condition for the time that the shared channel that the scheduling information of downlink data indicates is released.

Optionally, the scheduling restricted information includes the time range information that preconfigured second equipment occupies shared channel；First equipment described in above-mentioned steps 101, which determines, assesses the initial time whether shared channel is in idle condition, and concrete implementation method may is that the initial time that the end time for the time range information instruction that the second equipment described in the scheduling restricted information occupies shared channel is determined as assessing whether the shared channel is in idle condition by first equipment.

Specifically, scheduling restricted information can be semi-persistent scheduling information, the time range that each equipment in communication system respectively occupies shared channel is allocated in advance, such as eNodeB can only be in the time range of the downlink subframe pre-seted to UE transmission downlink data, first equipment is according to scheduling restricted information you can learn that the second equipment occupies the time range of shared channel, so that it may be determined as assessing the initial time whether shared channel is in idle condition for the end time for dispatching the time range information instruction that the second equipment in restricted information occupies shared channel.

Optionally, what the first equipment received is above-mentioned broadcast message, scheduling instruction information, any two or when three information in scheduling restricted information, first equipment can determine that is assessed the initial time whether shared channel is in idle condition respectively according to the corresponding process of above-mentioned three category information, and then the first equipment finally determines an initial time according to the demand of transmission data.Such as, the scheduling that first equipment receives broadcast message and the resource scheduling information including the transmission upstream data that the second equipment is the distribution of the first equipment indicates information, at this moment for the first equipment due to the available time to the corresponding upstream data of transmission, the first equipment can take the initial time determined according to scheduling instruction information；First equipment receives broadcast message and scheduling restricted information, and at this moment since scheduling restricted information is specially to be sent to the first equipment, the first equipment can take the initial time determined according to scheduling restricted information.The mistake for sharing the initial time whether channel is in idle condition is assessed it should be noted that receiving much information to the first equipment herein and determining Journey is exemplary illustration, and the first equipment can also be not specifically limited in this embodiment according to the case where actual transmission data and demand with other rules takes corresponding initial time.

Optionally, first equipment described in above-mentioned steps 101, which determines, assesses the initial time whether shared channel is in idle condition, and concrete implementation method may is that first equipment will be determined as assessing the initial time whether shared channel is in idle condition with the second equipment pre-set time.

Specifically, what a time the first equipment and the second equipment can preset before a communication, and the time of the setting can be determined as assessing the initial time whether shared channel is in idle condition by the first equipment.

Optionally, the duration of the default assessment time includes the length of at least one preset time period.

Specifically, preset time period is that the first equipment evaluation once shares whether channel is in idle condition the required time, its duration is also possible to by preconfigured one on the middle and senior level fixed duration of communication system, it is also possible to one that the first equipment and the second equipment are arranged in advance before communicating fixed duration, and the duration of default assessment time includes the length of at least one preset time period.Such as the length of a preset time period is 20 μ s or 18 μ s, is illustrated by taking 20 μ s as an example below.The duration of assessment time default in this way can be a 20 μ s, be also possible to P 20 μ s, P be it is preset be greater than 1 natural number.

Optionally, first equipment described in above-mentioned steps 102 assesses whether the shared channel is in idle condition within the default assessment time since the initial time, if concrete methods of realizing may is that first equipment it is described it is default assessment the time in assess the shared channel energy value be higher than predetermined power judge thresholding, it is determined that the shared channel is not at idle state；If the energy value that first equipment assesses the shared channel within the default assessment time judges thresholding less than or equal to the predetermined power, it is determined that the shared channel is idle state.

Specifically, first equipment is the initial time whether being in idle condition since the determining assessment shared channel, the state of shared channel is detected in the duration of default assessment time, if detecting that the energy value of the shared channel judges thresholding less than or equal to predetermined power within the default assessment time, it is determined that the shared channel is idle state；If detecting within the default assessment time, the energy value of the shared channel is higher than predetermined power and judges thresholding, and the first equipment determines that the shared channel is not at idle state.It is equivalent that the energy value of shared channel can be channel quality, interference, power that the first equipment measures on a shared channel.
