Description
Technical field
The present invention relates to wireless communication technology field, in particular to a kind of method and apparatus of channel access.
Background technique
With the continuous growth of mobile data services amount, frequency spectrum resource is more and more nervous, be used only authorization frequency spectrum resource into
The deployment of row network and business transmission may be no longer satisfied traffic needs, therefore LTE (Long Term Evolution, length
Phase evolution) system can be considered in unlicensed spectrum resource deployment transmission (Unlicensed LTE, referred to as U-LTE or
LTE-U), to improve user experience and spread over.
Unlicensed spectrum does not plan specific application system.That is, unlicensed spectrum can be a variety of channel radios
Letter system such as bluetooth, WiFi etc. is shared, uses shared unlicensed spectrum resource between multiple systems by way of preempting resources.
Therefore the compossibility of the wireless communication systems such as LTE-U and WiFi of different operator's deployment is an emphasis and difficult point for research.
3GPP requires to guarantee the fair co-existence of the wireless communication systems such as LTE-U and WiFi, and unauthorized frequency range is as secondary carrier by authorization frequency
The main carrier of section assists realizing.Basic hand of the LBT (listen Before Talk, listem-before-talk) as LTE-U contention access
Section, obtains the approval of nearly all company.
802.11 systems are known as carrier sense/conflict avoidance (CSMA/CA) mechanism, WiFi system using Channel Access Mechanism
Preempting resources mode in unlicensed spectrum: first monitoring channel, when the channel is idle between reach DIFS
(Distributed Inter-Frame Space, distributed interframe gap), just judge present channel for idle channel, then
The website of the channel to be accessed such as each just enters a random back stage, for avoiding multiple websites in identical resource
It collides.In addition, it further provides that each website cannot occupy frequency spectrum resource for a long time, reaching certain time to guarantee fairness
Or when the volume of transmitted data upper limit, need to discharge resource, for other WiFi or LTE system preempting resources.
In order to provide a flexible fair adaptive channel access mechanism, unauthorized 5150-5350MHz with
5470-5725MHz frequency range can use LBT technology.LBT process is similar to the CSMA/CA mechanism of WiFi, each equipment utilization channel
CCA (Clear Channel Assessment, clear channel assessment (CCA)) detection is carried out before.ETSI (European Telecommunication Standard
Association) device class of unauthorized frequency range is that fame-based (based on fixed frame structure) (is based on load-based by standard
Business load), respectively correspond two class access mechanisms: Frame Based Equipment (based on anchor-frame structural device, FBE)
With Load Based Equipment (being based on business load equipment, LBE).
As long as FBE access, which executes CCA detection channel in fixed frame structure position, a CCA period (not less than 20us)
It is judged as empty and just accesses channel at once, initiates data transmission procedure, channel transmission time holding time is relatively fixed, minimum 1ms
Maximum 10ms, idling cycle should be at least the 5% of Channel holding time, the equipment within the CCA time of the tail portion of idling cycle
It executes new CCA detection and accesses channel again.Channel holding time adds the idle period to be that a fixed value is known as in FBE mechanism
Frame period (frame period).LBE Channel Access Mechanism, transmission is all variable to the holding time and starting point of channel every time
, it to be extended CCA detection before obtaining channel, a random factor N is generated, until idle time of channel reaches
N times of CCA time, and channel is the spare time, just accesses channel, initiates data transmission procedure, maximum Channel holding time is 13ms.
FBE Channel Access Mechanism, suitable for there is the wireless access system of fixed frame structure, to the LTE system of unauthorized frequency range
For system, when only one operator coexists with WiFi, very simple, very attractive, Er Qieyou is operated using FBE mode
In use FBE mode since CCA detection can only be carried out in the idle period, therefore the LTE node pair of a FBE access mechanism is added
The influence of WiFi is smaller, and is significantly lower than LBE- using standardization complexity Project Realization complexity needed for FBE-LTE-U
LTE-U, performance may not be more far short of what is expected than LBE-LTE-U.Therefore selected according to FBE access mechanism+carrier wave, special different operators are logical
It crosses carrier wave selection and occupies different channels respectively, be the preferable selection of one kind of LTE-U.But there is many not in unlicensed band
Same broadband wireless access network, when dog-eat-dog, identical frequency spectrum resource is inevitably shared by different operators, so
And according to current existing processing method, can there is a problem of serious, be 3 sons as Liang Ge operator takes the maximum transmitted period
Frame, idling cycle are 1 subframe, and fixed frame period is 4 subframes, with Down Link only (only downlink)
For, when Liang Ge operator is able to maintain synchronous, since the CCA detection Shi Douhui in each idling cycle is judged as not busy, therefore
It sends simultaneously, the transmission of Liang Ge operator is caused all to be collided in the time for having common service
How multi-operator uses FBE access mechanism work clear method not yet in unlicensed spectrum at present.

Network side equipment described in the embodiment of the present invention is put after the network side equipment for determining other operators has business demand
Abandon the fixed frame period in access part.After having business demand in the network side equipment for determining other operators, abandon
The fixed frame period in access part, to realize that multi-operator is worked in unlicensed spectrum using FBE access mechanism；Into
The performance of one step raising whole system.
When the network side equipment of different operators of the embodiment of the present invention uses FBE Channel Access Mechanism, each operator
Whether the network side equipment that network side equipment first detects same other operators of frequency has business demand, has business to need in other operators
When asking, the competition and transmission opportunity using the fixed frame period in part are abandoned.Different operators are fixed by abandoning part
It is same between frame period realization operator to coexist frequently.
The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, the method for one channel access of the embodiment of the present invention includes:
Step 101, network side equipment judge whether the network side equipment of other operators of same frequency has business demand；
Step 102, the network side equipment are abandoned connecing after the network side equipment for determining other operators has business demand
It is fixed frame period (frame period) to enter part.
Wherein, network side equipment abandons the fixed frame period in access part, while also abandoning fixing in this section
It is transmitted on frame period.
Specifically, the network side equipment not monitor channel in the frame period abandoned, or lasting monitor channel,
And data are not transmitted in the frame period abandoned.
Network side equipment monitor channel within the CCA period before all non-fixation frame period for abandoning access, if
Channel idle then accesses fixation frame period and carries out data transmission.UE is still according to original side in the subframe for abandoning access
Case receive, by taking down link only as an example, UE on the carrier wave of activation can each subframe parse PDCCH/ePDCCH, if
Network side equipment does not parse control signaling, then does not carry out subsequent processing to the subframe.
Preferably, after the network side equipment abandons the fixed frame period in access part, it can also be to the portion abandoned
Fixed frame period is divided to continue to monitor.
Wherein, the network side equipment judges whether the network side equipment of other operators has the method for business demand to have very
It is a variety of.It is set forth below several.
Mode one, network side equipment judge other fortune according to the traffic load information of the network side equipment of other operators
Whether the network side equipment of battalion quotient has business demand.
For example, network side equipment can indicate to correspond in the traffic load information for the network side equipment for determining other operators
Network side equipment when having load, determine that the network side equipment of other operators has business demand；
Network side equipment can also indicate corresponding in the traffic load information for the network side equipment for determining other operators
Network side equipment has a load, and when loading the threshold value for being greater than setting, determines that the network side equipment of other operators has business demand.
In an implementation, network side equipment can pass through X2 interface and/or the received network from other operators of eating dishes without rice or wine
Side apparatus is used to indicate the information of business load, and determines corresponding network side apparatus according to the information for indicating business load
Load.
If being received by X2 interface, network side equipment can receive it by the X2 interface between other network side equipments
The information for being used to indicate business load of his network side equipment.
If other network side equipments can be by way of being similar to discovery signal (DRS) by eating dishes without rice or wine to receive, the period
Transmission for indicating the information of business load.
In an implementation, network side equipment by X2 interface and/or can also eat dishes without rice or wine to send itself to other network side equipments
For indicating the information of business load.
Wherein, for indicating that the information of business load can be specific load value；It is also possible to be according to common
Load information is quantified as a value of a reflection load level by agreement, can such as be reflected with the occupancy situation of buffer negative
Carry information content.
It should be noted that the parameter that different system measures load may be different, for example, LTE can use number of users as
The parameter of load；UMTS can use resource utilization as load parameter, so if network side equipment need will load with
Threshold value is compared to judge whether there is business demand, then needs to select the corresponding threshold value of different loads, such as load to use
Amount then selects the corresponding threshold value of number of users.
Mode two, network side equipment according to the network side equipments of other operators report for having indicated whether business
The information of demand, judges whether the network side equipment of other operators has business demand.
For example, the network side equipment of other operators can directly report whether have business demand to network side equipment.Than
It such as 1 indicates, 0 indicates do not have, if by reporting 1；Otherwise 0 is reported.
In an implementation, network side equipment can pass through X2 interface and/or the received network from other operators of eating dishes without rice or wine
The information for being used to indicate whether business demand of side apparatus, and according to determining pair of the information for indicating whether business demand
Whether the network side equipment answered has business demand.
If being received by X2 interface, network side equipment can receive it by the X2 interface between other network side equipments
The information for being used to indicate whether business demand of his network side equipment.
If other network side equipments can be by way of being similar to discovery signal (DRS) by eating dishes without rice or wine to receive, the period
Transmission for indicating whether the information of business demand.
Wherein, the network side equipment is abandoned accessing after the network side equipment for determining other operators has business demand
When frame period is fixed in part, the fixed frame period in part can be abandoned at random, it can also be according to pre-set
Rule abandons the fixed frame period in part.
Specific rule can be set as needed.For example rule is abandons ratio, then network side equipment is determining other
After the network side equipment of operator has business demand, according to ratio of abandoning, the fixed frame in the part for needing to abandon is determined
Period, and abandon the fixed frame period in the determining part of access.
Preferably, the network side equipment abandons ratio according to the determination of one of following manner:
The network side equipment, which determines, preset abandons ratio；
The network side equipment is according to the network side equipment of itself business load and other operators for having business demand
Business load, determination abandon ratio.
In an implementation, the ratio of abandoning of different network side equipments may be the same or different.It specifically can be according to need
It sets.As long as such as find that the network side equipment of other operators has business demand, actively abandon 50% fixation frame
The access and transmission opportunity of period.
The network side equipment is according to the network side equipment of itself business load and other operators for having business demand
Business load, determine when abandoning ratio, traffic load level and other operators of the base station of each operator according to oneself
Traffic load level determine the ratio of fixation frame period that oneself should actively abandon, such as assume operator 1
Load be A, fortune supplier 2 load be B, then operator 1 determines the fixation that oneself should be abandoned according to the ratio A/B of load
The ratio of frame period.
The fixation frame that oneself should be abandoned can also be determined according to the ratio A/B of load and the threshold value of setting
The ratio of period.Specifically, the ratio that ratio abandons fixed frame period greater than threshold value can be set, ratio is not
Greater than the ratio that threshold value abandons fixed frame period.If other side's load is one times of one's own side, the fixation abandoned is conceded
The ratio of frame period is then greater than half.Specific ratio can be determined by emulation.
It should be noted that the embodiment of the present invention be not limited to it is above-mentioned using ratio of abandoning as rule mode, other
It can guarantee that network side equipment abandons the mode of the fixed frame period in part and all can serve as the rule of the embodiment of the present invention.
For example start side load and be significantly larger than another party, it loads low side and continuously abandons approaching until both sides load.
Preferably, can also continue to monitor after the network side equipment abandons the fixed frame period in access part
Channel；According to the channel status listened to, after determining that needing to adjust the part for abandoning access fixes frame period, adjustment
Abandon the fixed frame period in part of access.
For example it is always sky that network side equipment, which listens to the channel status of the fixed frame period in the part oneself abandoned,
Not busy state, and the channel status for the fixed frame period in part not abandoned is always busy state, and is not accessed always,
After when reaching setting, it can determine and need to adjust the fixed frame period in part for abandoning access, abandon busy state
The fixed frame period in part.
Also such as network side equipment is monitored in the subframe that oneself should be able to be accessed, it is found that some subframes can access,
Some subframes cannot access, then the yielding pattern of oneself is adjusted according to channel situation.
Below by taking two operators respectively abandon the fixation frame period of 50% ratio as an example, illustrate to may be implemented with frequency altogether
It deposits.Assuming that operator 1 abandons the fixed frame period of odd number, operator 2 abandons the fixed frame period of even number, with fixation
Frame period is 4 subframes, by taking Down Link only as an example, as shown in Figure 2.
Here abandon referring to is not accessed and is not transmitted, but can continue to monitor, for example monitors current fixed frame
The CCA of period, if next fixed frame period can be accessed according to determination is monitored, but next fixation
Frame period has been abandoned, then is not accessed, if do not abandoned, is accessed.
Fill part indicates the part in the fixed frame period of access channel for data transmission in Fig. 2, it is seen that this
When take full advantage of time-division principle Liang Ge operator Fairshare channel.
If the fixed frame period of even number is made a concession in lucky two operation commercial cities, due to being asynchronous between Liang Ge operator
, therefore odd number is necessarily caused necessarily to have an operator first to access when fixing frame period, if operator 2 first accesses, this
The fixed frame period of sample even number just without business, since operator base station continues monitor channel, therefore has found that even number is fixed
Just without business, the fixed frame period of odd number cannot get by competition frame period, can determine what needs adjustment was abandoned
The fixed frame period of the odd number abandoned is abandoned the fixed frame of even number by the fixed frame period in part instead
Period, to realize the preferably shared channel of Liang Ge operator.
Wherein, the network side equipment of the embodiment of the present invention can be base station (such as macro base station, Home eNodeB etc.), can also be with
It is RN (relaying) equipment, can also be other network side equipments for needing to access channel.
