Description

Configurating channel is measured and carries out the method for up channel measurement, system and equipment

Technical field

The present invention relates to wireless communication technology field, measure particularly to a kind of configurating channel and carry out up channel measurement Method, system and equipment.

Background technology

The basic duplex mode that cellular system is used, TDD (Time division duplex, time division duplex) mould Formula refers to that uplink downlink uses same working band, carries out the transmission of uplink and downlink signals in different time intervals, on Protected interval (Guard Period, GP) between descending；FDD (Frequency division duplex, FDD) mould Formula then refers to that uplink downlink uses different working bands, can be engraved on different frequency carriers and carry out up and down when same The transmission of row signal, protected bandwidth (Guard Band, GB) between up-downgoing.

The frame structure of LTE (Long Term Evolution, Long Term Evolution) TDD system is the most more complex, as it is shown in figure 1, One a length of 10ms of radio frames, comprises special subframe and conventional subframe two class totally 10 subframes, and each subframe is 1ms.Special Subframe is divided into 3 subframe: DwPTS (Downlink Pilot Time Slot, descending pilot frequency subframe)；GP is used for downlink and uplink Between protection interval)；UpPTS (Uplink Pilot Time Slot, ascending pilot frequency subframe).Conventional subframe includes up son Frame and descending sub frame, be used for transmitting uplink/downlink and control channel and business datum etc..The most in a radio frame, Ke Yipei Put two special subframes (being positioned at subframe 1 and 6), it is also possible to configure a special subframe (being positioned at subframe 1).Subframe 0 and subframe 5 with And the DwPTS subframe in special subframe is always used as downlink transfer, the UpPTS subframe in subframe 2 and special subframe is always used In uplink, other subframes can be configured for use as uplink or downlink transfer according to needs.

In TDD system, uplink and downlink transmission uses identical frequency resource, transmits uplink/downlink on different sub frames Signal.In common TDD system, including TD-SCDMA (TD SDMA) system and the TD-LTE system of 4G of 3G System, the division of uplink and downlink subframe is static or semi-static, it is common practice to according to community in network planning process Type and business proportion substantially determine ascending-descending subframes ratio cut partition and keep constant.This is under the background of the big covering of macrocell It is relatively simple way, and the most effective.And along with technology develops, increasing Microcell (Pico cell), family The low power base station such as base station, front yard (Home NodeB) are deployed the little covering for providing local, in this kind of community, number of users Measuring less, and customer service changes in demand is relatively big, therefore there is situation about dynamically changing in the up-downgoing business proportion demand of community.

In the case of multiple cell networking, in traditional TDD network, different districts uses identical uplink-downlink configuration, therefore exists On sub-frame of uplink or on descending sub frame, base station or UE are disturbed by the adjacent cell as shown in Fig. 2 A or Fig. 2 B:

Type 1 adjacent cell is disturbed: in the subframe that neighbor cell all carries out downlink transfer, the descending acceptance of local area UE is subject to The interference of neighbor base station downstream signal；

Type 2 adjacent cell is disturbed: in the subframe that neighbor cell all carries out uplink, it is up that local area base station accepts UE Signal can be disturbed by adjacent area UE upward signal.

Meanwhile, in multiple cell networking, if the different up-downgoing ratio of adjacent cell configuration, then be likely to occur as Interference at crossed slot shown in Fig. 3.In figure 3, macrocell is on the time slot sending downstream signal, and Pico cell is for up Signal receives, and occurs two kinds of interference between Ze Liang community.

In dynamic TDD system, owing to there is constant transmissions direction and the subframe in variable propagation direction, variable at each In subframe, owing to the transmission direction of adjacent area is flexibility and changeability, and local area there may be more than one strong jamming adjacent area, because of This local area experienced interference type is likely to different.Under extreme case, in each variable subframe, local area is used for downlink transfer In be subject to adjacent area interference be different from.On the different sub-frame of uplink of dynamic TDD system, due to the difference of adjacent area interference, lead Cause actual channel situation and have marked difference, SRS (the Sounding Reference measured on a certain sub-frame of uplink Signal, detection reference signal) it is not particularly suited on other descending sub frames with different adjacent areas disturbed condition.Such as solid The channel situation determining to measure on sub-frame of uplink is not particularly suited for variable sub-frame of uplink, measures and arrive on a certain variable sub-frame of uplink Channel situation be not particularly suited for other variable sub-frame of uplink.For these reasons, adopt in LTE Rel-8/9/10 at present Configurating channel measure and up channel measure and inapplicable dynamic TDD system.

In sum, current dynamic TDD system does not also have a kind of configurating channel measure and carry out up channel measurement side Method.

Detailed description of the invention

Sub-frame of uplink is divided into multiple up according to the disturbed condition on sub-frame of uplink by embodiment of the present invention network equipment Subframe group, and the channel measurement configuration information that notifying user equipment is corresponding with sub-frame of uplink group.Owing to network equipment notice is used Channel measurement configuration information corresponding to multiple sub-frame of uplink groups that family equipment divides according to the disturbed condition on sub-frame of uplink, thus Achieve configurating channel in dynamic TDD system to measure.

The channel measurement corresponding with sub-frame of uplink group that embodiment of the present invention subscriber equipment receives from network equipment is joined Confidence ceases, and carries out up channel measurement according to channel measurement configuration information.Owing to subscriber equipment is according to channel measurement configuration information Carry out up channel measurement, it is achieved thereby that carry out up channel measurement in dynamic TDD system；Further such that network side sets The standby channel situation that can accurately obtain the sub-frame of uplink with disturbance situation, and carry out disturbing feelings according to this channel situation The scheduling of the sub-frame of uplink that condition is similar, solves the different subframe adjacent areas notable situation of change of disturbed condition in dynamic TDD system Under up channel situation measure problem, improve systematic function.

Wherein, the radio frames in the ascending type configuration that the present embodiments relate to includes: variable subframe, descending stator Frame, up fixing subframe and special subframe, wherein, descending fixing subframe be transmission direction be down direction and transmission direction fix Constant subframe, and the descending pilot frequency time slot in special subframe, up fixing subframe be transmission direction be up direction and biography The changeless subframe in defeated direction, variable subframe be transmission direction-agile subframe, variable subframe still further comprise up can Varitron frame and descending variable subframe, up variable subframe is to be defined as the variable subframe as uplink, descending variable subframe For being defined as the variable subframe as downlink transfer.

Uplink pilot time slot in embodiment of the present invention special subframe and up in the special subframe in background technology are led Frequently the function of time slot is identical, and explanation is not repeated.

The embodiment of the present invention can be applied in TDD system (such as TD-LTE system), it is also possible to is applied to other needs Dynamically adjust in the system of subframe uplink-downlink configuration, such as TD-SCDMA system and follow-up evolution system, WiMAX (Worldwide Interoperability for Microwave Access, micro-wave access global inter communication) system and thereafter Continuous evolution system etc..

In order to support to use more descending sub frame, a fixing up son can be only set in a radio frames Frame, i.e. arranging subframe 2 is up fixing subframe, and subframe 0 and subframe 5 are descending fixing subframe, and subframe 1 is special subframe, subframe 6 For special subframe or descending sub frame (transmission direction is descending subframe), remaining subframe is variable subframe；

Wherein, when subframe 7 for sub-frame of uplink (i.e. subframe 7 be that to transmit direction be up variable subframe, the most up can varitron Frame) time, then subframe 6 is special subframe, wireless frame structure as shown in Figure 4 A；

When subframe 7 is descending sub frame (i.e. subframe 7 be that to transmit direction be descending variable subframe, the most descending variable subframe) Time, subframe 6 is descending sub frame (i.e. transmission direction is descending subframe), wireless frame structure as shown in Figure 4 B；At this frame structure Under, maximum descending (DL) subframe that can support is 9: 1 with the ratio of up (UL) subframe, so that in dynamic TDD system The dynamic range of resource-adaptive is bigger, preferably mates the change of business.

Wherein, sub-frame of uplink is divided into multiple according to the disturbed condition on sub-frame of uplink by embodiment of the present invention network equipment During sub-frame of uplink group, the sub-frame transmission direction that can dispatch as required and the subframe of the strong jamming community adjacent with Target cell Configuration information, is divided into multiple sub-frame of uplink group by the subframe in a radio frames.

It is preferred that according to a kind of judgement community adjacent with Target cell in following manner whether network equipment can It is strong jamming community:

(1) network equipment is according to the signal intensity of the community adjacent with Target cell detected, it is judged that little with target Whether adjacent community, district is strong jamming community, is such as compared with threshold value by signal intensity, if greater than threshold value, it is believed that should Community is strong jamming community；

(2) network equipment according to belong to Target cell user equipment to report produce community corresponding to strong jamming community Mark, it is judged that whether the community adjacent with Target cell is strong jamming community, such as can specify that subscriber equipment pair is little with target The signal intensity of the community that district is adjacent detects, if signal intensity is more than threshold value, then reports the cell ID of this community, phase The network equipment answered after receiving cell ID using corresponding community as strong jamming community；

(3) network equipment is after receiving the announcement information that the community adjacent with Target cell sends, and determines that this community is The strong jamming community adjacent with Target cell, wherein announcement information is that the community adjacent with Target cell is little according to the target received District send signal intensity determine self be Target cell strong jamming community after send, such as adjacent area can be measured disturbed The signal of community, if path loss is less, then it is assumed that the strong jamming community of oneself Shi Gai community, then by the signaling of network interface Notify this community.

It should be noted that the embodiment of the present invention is not limited to above-mentioned 3 kinds of modes, other can interpolate that and Target cell Whether adjacent community is the equally applicable embodiment of the present invention of mode of strong jamming community.

It is preferred that network equipment can obtain the strong jamming community adjacent with Target cell by interface signaling notice Subframe configuration information, it is also possible to autonomous detection obtains the subframe configuration information of the strong jamming community adjacent with Target cell.Certainly, Other are obtained in that the mode of subframe configuration information is also suitable the embodiment of the present invention, notify network by subscriber equipment after such as being obtained Side apparatus.

In force, network equipment can be up or fixing containing uplink pilot time slot by transmitting direction in community Sub-frame division is in a sub-frame of uplink group, and is that up variable sub-frame division is to extremely by transmitting direction in Target cell In a few sub-frame of uplink group.

Such as in 7 kinds of sub-frame configuration of TDD, all sub-frame of uplink in a radio frames being divided into two classes, a class is The changeless subframe in neighbor cell configuration direction, another kind of be neighbor cell configuration direction it may happen that the subframe of change (subframe is compiled here Number be the subframe number in a radio frames, i.e. N={0,1,2 ... 9}):

The changeless subframe in neighbor cell configuration direction, the subframe 0 in the most each radio frames, 1,2,5,6, wherein subframe 0, 1,5,6 is fixed as descending sub frame (or the subframe containing descending pilot frequency time slot), and subframe 2 is fixed as sub-frame of uplink.For in subframe 0,1,5,6 these 4 descending sub frames, owing to adjacent area interference is from the uplink interference of base station, it is believed that base station is at these Interference suffered by subframe is of substantially equal, so sub-frame of uplink 2 forms a sub-frame of uplink group；The most again will be at Target cell Middle transmission direction is up variable sub-frame division at least one sub-frame of uplink group, the subframe 3,4 in the most each radio frames, 7,8,9 is variable subframe, then by subframe 3, the quantity of 4,7,8, the 9 sub-frame of uplink groups divided is not more than subframe 3, in 4,7,8,9 Number for sub-frame of uplink.

It is preferred that variable subframe can also be divided into the two variable subframes of class by network equipment, the variable subframe of the first kind be Transmitting direction in strong jamming community is all up variable subframe, and the variable subframe of Equations of The Second Kind is to transmit in part strong jamming community Direction is up variable subframe.

Then, network equipment is by variable for first kind sub-frame division to sub-frame of uplink group；And can by Equations of The Second Kind Varitron frame is divided at least one sub-frame of uplink group, the variable subframe of Equations of The Second Kind in each sub-frame of uplink group after wherein dividing Direction is transmitted identical in each strong jamming community.

Concrete, if all adjacent areas are all identical with Target cell in the direction of present sub-frame, it is the most all up, the most permissible This subframe and subframe 2 are classified as same sub-frame of uplink group；

If there being one or more adjacent area different from Target cell in present sub-frame direction, then can draw multiple disturber To combination, the subframe with same disturbance directional combination is placed in same sub-frame of uplink group.

Assume that Target cell is sub-frame configuration 6；There are 2 strong jamming adjacent areas, time slot configuration is respectively configuration 1 and configuration 2. As shown in table 1:

Subframe 2 is that transmission direction is up fixing subframe in Target cell；

Subframe 3,4,7,8 is that transmission direction is up variable subframe in Target cell, and subframe 7 is in community 1 and community 2 Middle transmission direction is all up, so the subframe 7 variable subframe that is the first kind, subframe 7 is put in sub-frame of uplink group, the most up son Frame group includes subframe 2,7.

Subframe 3,4, the transmission directional combination in community 1 and community 2 of 8 correspondences is respectively as follows: (U, D), (D, D), (U, D).

Due to subframe 3 and subframe 8, the transmission directional combination in community 1 and community 2 is all (U, D), so by subframe 3 and son Frame 8 is divided in a sub-frame of uplink group, subframe 4 is divided in a sub-frame of uplink group.

Except mode above, the embodiment of the present invention can also be using each descending sub frame as a sub-frame of uplink Group；Can also fix subframe and be divided into one group, variable subframe is divided into one group.

It should be noted that the embodiment of the present invention is not limited to above-mentioned dividing mode, other can be according to descending sub frame On disturbed condition divide sub-frame of uplink group mode be all suitable for the embodiment of the present invention.

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

In following declarative procedure, first implement to illustrate from the cooperation of network side and user equipment side, finally distinguish Illustrate from the enforcement of network side with user equipment side, but this does not imply that the two must coordinate enforcement, it practice, work as net When network side and user equipment side are performed separately, also solve respectively in the problem existing for network side, user equipment side, simply two When person is used in combination, superior technique effect can be obtained.

As it is shown in figure 5, the system that the embodiment of the present invention carries out up channel measurement includes: network equipment 10 and user set Standby 20.

Network equipment 10, for being divided into multiple sub-frame of uplink according to the disturbed condition on sub-frame of uplink by sub-frame of uplink Group, the channel measurement configuration information that notifying user equipment 20 is corresponding with sub-frame of uplink group；

Subscriber equipment 20, for receiving the channel measurement configuration letter corresponding with sub-frame of uplink group from network equipment 10 Breath, carries out up channel measurement according to channel measurement configuration information.

In force, the channel measurement configuration information of sub-frame of uplink group that network equipment 10 divides not will notify to Same subscriber equipment 20, network equipment 10 can select the channel measurement of which sub-frame of uplink group is configured letter as required Breath notice is to subscriber equipment 20.Ratio, then can be by the channel measurement of sub-frame of uplink group 1 and 2 if any sub-frame of uplink group 1,2,3,4,5 Configuration information notifies, to subscriber equipment a, to be notified by the channel measurement configuration information of sub-frame of uplink group 3 to subscriber equipment b, by up The channel measurement configuration information of subframe group 4 and 5 notifies to subscriber equipment c.For subscriber equipment, it is only necessary to join according to channel measurement Confidence breath is measured accordingly and feeds back, it is not necessary to know one has how many groups.

Wherein, embodiments provide two kinds of schemes carrying out up channel measurement, i.e. periodicity and aperiodicity, It is introduced separately below.

One, periodically up channel measurement is carried out.

Concrete, that network equipment 10 notifying user equipment 20 sub-frame of uplink group includes sub-frame of uplink；Accordingly, use Family equipment 20 receives the notice of the sub-frame of uplink that the sub-frame of uplink group from network equipment includes.

Such as, network equipment 10 informs the descending sub frame comprised in each group of subscriber equipment 20 by high-level signaling.

It is preferred that network equipment 10 determines SRS (the Sounding Reference corresponding with sub-frame of uplink group Signal, detection reference signal) parameter group, using the SRS parameter group corresponding with sub-frame of uplink group that determine as this up son The channel measurement configuration information that frame group is corresponding；

Accordingly, subscriber equipment 20 also sends corresponding with sub-frame of uplink group according to the SRS parameter group of configuration, period measurement SRS。

The parameter that SRS parameter group includes may refer to table 2.

SRS Transmission comb (i.e. the subcarrier number of SRS transmission)
	SRS transmission frequency domain original position
The SRS transmission persistent period (once transmits, be transmitted several times)
	The SRS transmission cycle with subframe relative to position
SRS transmission bandwidth
	SRS frequency hopping bandwidth
SRS transmission sequence cyclic shift
	The antenna port of SRS transmission

Table 2

It should be noted that the embodiment of the present invention is not limited to the content in table 2, other are relevant with channel measurement configuration Parameter can also serve as the parameter in SRS parameter group.

In force, network equipment 10 assembles the SRS parameter group put to different sub-frame of uplink is separate.

It is preferred that the SRS transmission subframe difference determined according to the SRS parameter group that any two sub-frame of uplink group is corresponding.

Concrete, subframe is that SRS sends the subframe relative position in a SRS transmission cycle relative to position.Network side Equipment 10 and subscriber equipment 20 according to the SRS transmission cycle with subframe relative to position, it is possible to determine SRS transmission subframe.

For a sub-frame of uplink group, subscriber equipment 20 carries out up according to the SRS parameter group that this sub-frame of uplink group is corresponding Channel measurement, and in the SRS transmission subframe determined according to corresponding SRS parameter group, send SRS.

Owing to the SRS transmission cycle in the SRS parameter group that different sub-frame of uplink groups are corresponding is the most different, it is possible to Occurring that SRS corresponding to different sub-frame of uplink group sends subframe is same subframe.Such as one SRS transmission cycle is 5ms, one The SRS transmission cycle is 10ms, it is likely that occurring that SRS corresponding to different sub-frame of uplink group sends subframe is same subframe.

If subscriber equipment 20 determines, according to the SRS parameter group that sub-frame of uplink group is corresponding, the SRS that different sub-frame of uplink group is corresponding When transmission subframe is same feedback subframe, according to the SRS parameter that a sub-frame of uplink group in different sub-frame of uplink groups is corresponding Group sends SRS.It is to say, when the SRS transmission subframe position that different sub-frame of uplink groups are corresponding is positioned at same subframe, according to The SRS parameter group of one of them sub-frame of uplink group sends SRS.

Two, aperiodicity carries out up channel measurement.

It is preferred that network equipment 10 determines the SRS parameter group corresponding with sub-frame of uplink group, by determine and sub-frame of uplink SRS parameter group corresponding to group is as channel measurement configuration information corresponding to this sub-frame of uplink group；

Accordingly, subscriber equipment 20 is according to the SRS parameter group of configuration, the SRS that period measurement is corresponding with sub-frame of uplink group.

The parameter that SRS parameter group includes may refer to table 2.

It is preferred that according to the SRS that SRS parameter group determines that states corresponding to any two sub-frame of uplink group, to send subframe different.

If subscriber equipment 20 determines, according to the SRS parameter group that sub-frame of uplink group is corresponding, the SRS that different sub-frame of uplink group is corresponding When transmission subframe is same feedback subframe, according to the SRS parameter that a sub-frame of uplink group in different sub-frame of uplink groups is corresponding Group sends SRS.It is to say, when the transmission subframe position that different sub-frame of uplink groups are corresponding is positioned at same subframe, according to it In a sub-frame of uplink group SRS parameter group send SRS.

Owing to being non-periodic feedback, after network equipment 10 is subscriber equipment 20 configurating channel measurement configuration information, also Need to trigger subscriber equipment 20 and trigger the SRS that family equipment 20 transmission is corresponding with at least one sub-frame of uplink group；Accordingly, Yong Hushe Standby 20, after the triggering receiving network equipment 10, determine this sub-frame of uplink according to the SRS parameter group corresponding with sub-frame of uplink group Organize a nearest SRS and send subframe, and send, at this SRS, the SRS that in subframe, transmission is corresponding with sub-frame of uplink group.

It is required for sending SRS it is to say, the most each SRS sends subframe, needs the triggering according to network equipment 10 Determine at which SRS to send and in subframe, send SRS.

It is preferred that network equipment 10 can pass through PDCCH (Physical Downlink Control Channel, thing Reason down control channel) in SRS request (request) information trigger subscriber equipment send and at least one sub-frame of uplink group Corresponding SRS；Accordingly, subscriber equipment 20 is believed according to the SRS request in the PDCCH from network equipment 10 received Breath, needs to send after SRS determining, determines that this sub-frame of uplink group is nearest according to the SRS parameter group corresponding with sub-frame of uplink group One SRS sends subframe, and sends, at this SRS, the SRS that in subframe, transmission is corresponding with sub-frame of uplink group.

Such as carry SRS by the DL grant (downlink scheduling) or UL grant (uplink scheduling) of PDCCH Request information.

Wherein, have a variety of by the way of the triggering of SRS request information, be set forth below several.

Triggering mode one, SRS request information are 1 bit, then bit indicates whether to trigger feedback.

If it is preferred that receive the PDCCH comprising SRS request information in subframe n, and SRS request information Instruction needs to send SRS, and subscriber equipment 20 sends SRS in subframe n+k；Wherein, k >=m, m are the user in units of subframe Equipment processes the time, and subframe n+k is the SRS transmission subframe that distance subframe n is nearest.

Wherein, the process time of subscriber equipment includes subscriber equipment reception and processing controls signaling, carries out CSI measurement, on The time that row sends etc. (the process time of the subscriber equipment of follow-up appearance, with here like, is not repeated to introduce).Such as The process time of general user's equipment is the length of 4 subframes, i.e. 4ms.

Such as SRS request information is 1 bit, triggers feedback, do not trigger feedback when bit is 0 when bit is 1.According to The SRS request information received in subframe n, when SRS bit is 1, sends aperiodic SRS, wherein k in subframe n+k >=4 and n+k is to transmit subframe apart from the aperiodic that subframe n is nearest.

Assume have sub-frame of uplink group 1 and 2 two groups, when the SRS that subframe n+k is sub-frame of uplink group 1 correspondence sends subframe, Then send SRS according to the SRS parameter of subframe group 1；When the SRS that subframe n+k is sub-frame of uplink group 2 correspondence sends subframe, then press SRS parameter according to subframe group 2 sends SRS.When the bit in SRS request information is 0, do not send SRS.

Triggering mode two, SRS request information are many bits, by the multiple bit combination of SRS request information Instruction subscriber equipment feeds back the SRS which group sub-frame of uplink is corresponding.

Concrete, network equipment 10, according to sub-frame of uplink group and the corresponding relation of bit value, determines and needs to send SRS's The bit value that sub-frame of uplink group is corresponding, determines SRS request information, and the SRS that will determine according to the bit value determined Request information notifying user equipment 20；

Accordingly, subscriber equipment 20, according to sub-frame of uplink group and the corresponding relation of bit value, determines SRS request information Sub-frame of uplink group corresponding to bit value, and determine nearest one according to the SRS parameter group that the sub-frame of uplink group determined is corresponding SRS sends the position of subframe, and sends, at this SRS, the SRS that in subframe, transmission is corresponding with this sub-frame of uplink group.

Such as subscriber equipment 20 determines the SRS needing feeding back uplink subframe group a, then subscriber equipment 20 is according to sub-frame of uplink group A SRS after SRS parameter group corresponding for a determines sends subframe, and sends transmission and sub-frame of uplink group in subframe at this SRS The SRS that a is corresponding.

If it is preferred that receive the PDCCH comprising SRS request information in subframe n, and SRS request information Instruction needs to send SRS, and subscriber equipment 20 is in subframe n+k_iUpper transmission SRS；Wherein, k_i>=m, m are the user in units of subframe Equipment processes time, and subframe n+k_iThe SRS corresponding for the i-th sub-frame of uplink group that distance subframe n is nearest sends subframe, and i is Less than or equal to the positive integer of N, and i is the sub-frame of uplink group sequence number needing to send SRS triggered by SRS request information, and N is The number of sub-frame of uplink group

As a example by 2 bits, as shown in table 3, subscriber equipment 20 receives the DL carrying SRS request information in subframe n Grant or UL grant, then sending SRS, wherein k1 >=4, k2 >=4, and subframe n+k1 in subframe n+k1 and/or n+k2 is distance The SRS of the corresponding subframe group 1 that subframe n is nearest sends subframe, and subframe n+k2 is the SRS of the nearest corresponding subframe group 2 of distance subframe n Send subframe.Respective SRS parameter is used when transmitting the SRS signal of subframe group 1 or 2.When by subframe k1 that as above rule determines During=k2, one group of parameter is only used to send SRS.

SRS request information bit	Description (describes)
		00	Do not trigger SRS
01	Trigger the SRS of sub-frame of uplink group 1
		10	Trigger the SRS of sub-frame of uplink group 2
