The application is preferred embodiment described in detail below in conjunction with the accompanying drawings.

Embodiment one

The embodiment of the present application one provides the collocation method that a kind of CSI measures resource, and method is applied to network side equipment, for example：Base station, the adaptable scene of this programme is, for example,：TDD system, or other systems for needing to carry out CSI measurements and report, refer to Fig. 1, method specifically includes following steps：

Step S101:Network side equipment judges whether the descending sub frame of carrying cycle CSI measurement resources can use；Step S102:Network side equipment is unavailable constantly in the descending sub frame of carrying cycle CSI measurement resources, and corresponding cycle CSI measurements resource is sent by meeting the descending sub frame of preset rules. Wherein, in step S101, whether can use, be, for example, if judging the descending sub frame of carrying cycle CSI measurement resources：Judge whether the descending sub frame of carrying cycle CSI measurement resources is changed into sub-frame of uplink, wherein, when the descending sub frame for carrying cycle CSI measurement resources is changed into sub-frame of uplink, then show that the descending sub frame of carrying cycle CSI measurement resources is unavailable.

Fig. 2 is refer to, is the schematic diagram of dynamic TDD subframes proportioning, wherein, D and S represent descending sub frame, and U represents sub-frame of uplink, as seen from Figure 2, subframe proportioning mode during dynamic TDD subframes proportioning includes 7.

Wherein, in step S101, CSI measurements resource is, for example,：At least one of CSI-RS, CSI-IM resources resource, assuming that the subframe of carrying CSI-RS is the first subframe, the subframe for carrying CSI-IM resources is the 3rd subframe, 4 Jia set the first subframe and the 3rd subframe as identical subframe, so, it is then CSI-RS and CSI-IM resources that CSI, which measures resource,；When CSI measurement resources are CSI-RS, then guarantee in time to transmit CSI-RS to user equipment in the case where not increasing equipment processing load, and then can monitor in time and reporting status information of channel；When CSI measurement resources are CSI-IM resources, then guarantee in the case where not increasing equipment processing load in time by CSI-IM resource transmissions to user equipment, and then can monitor in time and reporting channel interference information.

In another example：First subframe is different subframes from the 3rd subframe, in this case, network side equipment then needs to determine whether the first subframe for carrying CSI-RS is changed into sub-frame of uplink and whether the 3rd subframe is changed into sub-frame of uplink respectively, in this case, it is then CSI-RS or CSI-IM resources that CSI, which measures resource,.

As shown in Figure 3, assuming that CSI-RS and CSI-IM resources are all carried on subframe 7, after system ratio of uplink subframe to downlink subframe is changed into subframe proportioning #1 from subframe proportioning #5, descending sub frame 7 originally just becomes for sub-frame of uplink, in this case, network side equipment then determines that the descending sub frame for carrying CSI-RS/IM resources is changed into sub-frame of uplink.

It is used as further preferred embodiment, before the corresponding cycle CSI measurements resource of descending sub frame transmission based on step S102 by meeting preset rules, the descending sub frame of preset rules is met firstly the need of determination, assuming that the descending sub frame for meeting the carrying CSI-RS of preset rules is the second subframe, the descending sub frame for meeting the carrying CSI-IM resources of preset rules is the 4th subframe, wherein, based on carrying CSI measurement moneys The difference of the subframe in source, it is determined that the mode for meeting the descending sub frame of preset rules is also different, will enumerate below it is therein it is several be introduced, certainly, in specific implementation process, however it is not limited to following several situations.

The first, first subframe is identical subframe with the 3rd subframe, in this case, both it can respectively determine to meet the descending sub frame of preset rules for CSI-RS and CSI-IM resources, a common descending sub frame for meeting preset rules can also be determined for CSI-RS and CSI-IM resources, both of these case respectively is introduced below.

(1) determine to meet the descending sub frame of preset rules respectively for CSI-RS and CSI-IM resources, in this case, if it is determined that the descending sub frame corresponding to CSI-RS is with determining the descending sub frame corresponding to CSI-RS using identical rule, so, the descending sub frame of the carrying CSI-RS finally determined and carrying CSI-IM resources is identical descending sub frame, and then using identical descending sub frame transmission CSI-RS/IM resources；And if it is determined that the descending sub frame corresponding to CSI-RS is from determining the descending sub frame corresponding to CSI-RS using different rules, the carrying CSI-RS so finally determined may be different descending sub frames from the descending sub frame for carrying CSI-IM resources, and then transmit CSI-RS and CSI-IM resources by different descending sub frames.Below the mode for determining the descending sub frame of carrying CSI-RS and carrying the descending sub frame of CSI-IM resources will be introduced respectively.

1) CSI, which measures resource, includes CSI-RS, and the mode of five kinds of second subframes of determination is explained below, certainly, in specific implementation process, following five kinds of modes are not limited to.

1. the nearest descending sub frame before determining the first subframe is used as the second subframe.

Or by taking the subframe proportioning shown in Fig. 2 and Fig. 3 as an example, wherein descending sub frame nearest before subframe 7 is subframe 5, so subframe 5 is defined as the second subframe.

Due in such scheme, the second subframe is not defined in same group of the first subframe, so the scope for being capable of selected descending sub frame is more extensive, and the second subframe of satisfaction can be determined in the place near the first subframe；

Further, descending sub frame before being the first subframe due to the second subframe of determination, and under normal circumstances, if UE reports CSI, all it is to select the sub-frame of uplink after the first subframe to be reported, so extending transmitting to UE time and UE for CSI-RS reports time interval between the CSI times, and then can extend the time that UE sides are detected by CSI-RS to channel situation. 2. determine to be used as the second subframe with descending sub frame of first subframe in same group.

In specific implementation process, subframe can be grouped according to multiple rule, for example：Be grouped, be grouped according to interference type according to level of interference etc..Exemplified by according to interference type different grouping, by taking the subframe proportioning cited by table 1 as an example, no matter how ratio of uplink subframe to downlink subframe changes, subframe 0 is all descending sub frame in all subframes proportioning, subframe 1 is all special subframe in all subframes proportioning, subframe 2 is all sub-frame of uplink in all subframes proportioning, therefore, and no matter how adjacent cell ratio of uplink subframe to downlink subframe changes all without the incorgruous interference of generation these subframes（For example：It is descending to it is up disturb, it is up to descending interference etc.）, so if according to whether can exist it is incorgruous interference come if being grouped to subframe, then subframe 0,1,2 can be divided into one group；Or matched according to the subframe of adjacent cell, this cell base station voluntarily judge which subframe may by adjacent cell incorgruous interfering subframe, by these, this subframe divides one group into, divide the subframe that can be only disturbed in the same direction into another set, as shown in Figure 4, according to the difference of adjacent cell interference type, descending sub frame 0,1,5,6 can be divided into identical subframe group, descending sub frame 3,7,8 can be divided into identical subframe group, and descending sub frame 4,9 can be divided into identical subframe group.

So, it is determined that during the second subframe, although descending sub frame 5 is the nearest subframe before subframe 7, but since it is desired that determining to be used as the second subframe with the descending sub frame in same group of subframe 7, so descending sub frame 5 is ineligible, and subframe 3, the subframe 8 with subframe 7 in same group are all changed into sub-frame of uplink, so as shown in Figure 5, need to continue to determine with descending sub frame of the subframe 7 in same group as the second subframe in previous frame, and then determine the subframe 8 of previous frame as the second subframe.Certainly, the subframe 8 of previous frame is not limited to here, can also be other subframes, such as：The subframe 7 of previous frame, subframe of previous frame 3 etc., the embodiment of the present application is not restricted.

3. determine to be used as the second subframe with nearest descending sub frame of first subframe in same group and before the first subframe.

Specifically, that is, the second subframe for being determined not only will be with the first subframe in same group, and the still nearest descending sub frame before the first subframe, for example：Scheme 2. the inside previous frame subframe 8.

4. determine the nearest available descending sub frame after the first subframe as the second subframe.

Or by taking the subframe proportioning shown in Fig. 5 as an example, the first subframe（Namely subframe 7) after it is nearest Descending sub frame is subframe 9, so subframe 9 is defined as the second subframe.

5. determine that the nearest available descending sub frame with the first subframe in same subframe group and after the first subframe is used as the second subframe.

2) CSI, which measures resource, includes CSI-IM resources, and three kinds of modes for determining to meet the descending sub frame of the carrying CSI-RS of preset rules are explained below, certainly, in specific implementation process, following three kinds of modes are not limited to.

1. determine to be used as the 4th subframe with available descending sub frame of the 3rd subframe in same subframe group.Due to determining that the mode of the available descending sub frame with the 3rd subframe in same subframe group is similar with the mode for determining the descending sub frame with the first subframe in same subframe group, so will not be repeated here.

Due in such scheme, it is determined that with descending sub frame of the 3rd subframe in same group as the 4th subframe, so the disturbed condition obtained in same disturbance environment can be detected, thus having to the more accurate technique effect of Interference Detection.

2. determine that the nearest available descending sub frame with the 3rd subframe in same subframe group and before the 3rd subframe is used as the 4th subframe.

Due to above having described the nearest descending sub frame how determined with the first subframe in same group and before the first subframe in detail, so repeat no more again.

In such scheme, the 4th subframe and the 3rd subframe are not only limited in same group, and its upper descending sub frame as the first subframe is limited, so both had to the more accurate technique effect of Interference Detection, while the time that UE is detected to disturbed condition can be extended again.

3. determine that the nearest available descending sub frame with the 3rd subframe in same subframe group and after the 3rd subframe is used as the 4th subframe.

(2) a common descending sub frame for meeting preset rules is determined for CSI-RS and CSI-IM resources.

Specifically, that is, not only the first subframe and the 3rd subframe are identical subframe, also, in the first subframe（3rd subframe）It is changed into after sub-frame of uplink, the 3rd subframe determined and the 4th subframe are also identical descending sub frame, that is, CSI-RS resources are carried with identical subframe 7 always with carrying CSI-IM resources. It foregoing describes because CSI-IM resources are the resource for carrying out channel condition information interferometry, so in order to ensure to obtain the disturbed condition in same disturbance environment, identified 3rd subframe（4th subframe）Needed with the first subframe in same group, and then, three kinds of modes for determining to meet the descending sub frame of preset rules will be introduced based on this below, certainly, in specific implementation process, be not limited to following two modes.

1. determine to be used as the second subframe with descending sub frame of first subframe in same group（4th subframe）.

2. determine and nearest descending sub frame second subframe of first subframe in same group and before the first subframe（4th subframe）.

3. determine to be used as the second subframe with nearest descending sub frame of first subframe in same group and after the first subframe（4th subframe）.

On specifically how to determine with descending sub frame of first subframe in same group, how to determine and nearest descending sub frame of first subframe in same group and before the first subframe and how to determine nearest descending sub frame with the first subframe in same group and after the first subframe, above it is being described, so will not be repeated here.

Second, the first subframe is different subframes from the 3rd subframe, in this case it is necessary to determine the second subframe and the 4th subframe for CSI-RS and CSI-IM resources respectively.

1) determination meets the second subframe of the carrying CSI-RS of preset rules, can in several ways determine, be set forth below five kinds therein and be introduced, certainly, in specific implementation process, be not limited to following five kinds of situations.

1. determine to be used as the second subframe with available descending sub frame of first subframe in same subframe group.

2. determine the nearest available descending sub frame after the first subframe as the second subframe.

3. the nearest available descending sub frame before determining the first subframe is used as the second subframe.

4. determine that the nearest available descending sub frame with the first subframe in same subframe group and before the first subframe is used as the second subframe.

2) determine to meet the 4th subframe corresponding to the carrying CSI-IM resources of preset rules, can pass through Various ways are determined, are set forth below three kinds therein and are introduced, certainly, in specific implementation process, are not limited to following three kinds of situations.

1. determine to be used as the 4th subframe with available descending sub frame of the 3rd subframe in same subframe group.

Further, the difference based on the descending sub frame for meeting preset rules determined before step S102, the mode for sending CSI-RS and CSI-IM resources is also different, is introduced separately below.

The first, first subframe and the 3rd subframe are identical subframe, and the second subframe and the 4th subframe determined also are identical descending sub frame, so, CSI-RS and CSI-RM resources can be sent by the identical descending sub frame determined.

Second, the first subframe and the 3rd subframe are identical subframe, but determine the second subframe and the 4th subframe not identical subframe, so sending CSI-RS by the second subframe, and send CSI-IM resources by the 4th subframe.

(3) first subframes and the 3rd subframe are different subframes, are changed into sub-frame of uplink if only the first subframe, then carried by the second subframe and transmit CSI-RS, and carried by the 3rd subframe and transmit CSI-IM resources；And it is changed into sub-frame of uplink if only the 3rd subframe, then carried by the first subframe and transmit CSI-RS resources, and the subframe for carrying CSI-IM resources by the 4th subframe carries and transmits CSI-IM resources；And in the case where the first subframe and the 3rd subframe are all changed into sub-frame of uplink, are then carried by the second subframe and transmit CSI-RS, and carried by the 4th subframe and transmit CSI-IM resources.

Further, because the descending sub frame that CSI measurement resources are carried and transmitted on network side equipment is changed（Such as：First subframe is changed into the second subframe or the 3rd subframe is changed into the 4th subframe）If UE sides are still with original subframe not changed（For example：First subframe or the 3rd subframe）Upper acquisition CSI measures resource, certainly it is to obtain to measure resource less than CSI, so UE side apparatus is it needs to be determined that meet the descending sub frame of preset rules, UE sides are described below to determine to meet the two ways of the descending sub frame of preset rules, certainly in specific implementation process, following two modes are not limited to. The first, before the descending sub frame transmission cycle CSI measurement resource by meeting preset rules, method also includes：

Network side equipment meets the configuration information of the descending sub frame of preset rules by signaling transmission to user equipment, so that user equipment determines to meet the descending sub frame of preset rules based on configuration information.

Specifically, that is, after the second subframe or the 4th subframe are determined in network side setting, the configuration information of the second subframe or the 4th subframe is sent to UE, such as：Send the second subframe or the 4th subframe numbering, in another example：The range information for sending second the first subframe of subframe distance or the range information for sending the subframe of the 4th subframe distance the 3rd can be determined the second subframe of corresponding carrying CSI-RS by these information or carry the 4th subframe of CSI-IM resources to UE, and then UE.

Due in such scheme, the configuration information of the descending sub frame of the carrying CSI measurement resources of preset rules can be met by signaled UE, so after the carrying CSI descending sub frames for measuring resource are changed into sub-frame of uplink, UE can also immediately determine that the corresponding carrying CSI for meeting preset rules measures the descending sub frame of resource, and then obtain corresponding CSI measurements resource.

Second, network side equipment and the pre-set identical default rules of UE, network side equipment is changed into the descending sub frame of carrying CSI measurement resources after sub-frame of uplink, the second subframe or the 4th subframe directly are determined according to default rule, CSI-RS is then sent by the 3rd subframe determined or CSI-IM resources are sent by the 4th subframe；

And UE is after the descending sub frame for detecting carrying CSI measurement resources is changed into sub-frame of uplink, determine that new carrying CSI measures the descending sub frame of resource according to default rule, because network side equipment and UE use identical default rule, so UE also determines the 3rd subframe or the 4th subframe, and then determine CSI-RS from the 3rd subframe or determine CSI-IM resources from the 4th subframe.

Due in such scheme, network side equipment and the pre-set descending sub frames for determining to meet the carrying CSI measurement resources of preset rules of UE, so during network side equipment and UE are communicated, flow need not be taken and inform that UE meets the descending sub frame of the carrying CSI measurement resources of preset rules by network side equipment, and then there are reduction network traffics, the technique effect of transmission blocking is prevented.

Further, in step S102, after the corresponding cycle CSI measurements resource of descending sub frame transmission by meeting preset rules, because the descending sub frame for meeting preset rules is measured with UE in carrying CSI Corresponding cycle CSI measurements resource is obtained from the descending sub frame for meet preset rules, for example：CSI-RS resources are determined from the second subframe, CSI-IM resources etc. are determined from the 4th subframe, are then detected by CSI-RS or CSI-IM resources, and then obtain corresponding CSI, for example：Detection acquisition channel situation is carried out by CSI-RS resources, disturbed condition etc. is obtained by the progress detection of CSI-IM resources.

In specific implementation process, corresponding cycle CSI measurements resource can measure resource for the CSI of a variety of situations, be set forth below three kinds therein and be introduced, certainly, in specific implementation process, be not limited to following three kinds of situations.

The first, when the descending sub frame for carrying cycle CSI measurement resources is changed into sub-frame of uplink, base station is that the descending sub frame for meeting preset rules configures cycle CSI measurement resource identical measurement resources a set of and before；

For example：When the first subframe is changed into sub-frame of uplink, when the corresponding CSI-RS resources that are carried in the second subframe are not changed into sub-frame of uplink with the first subframe on the CSI-RS that is carried be identical resource；Or, when the 3rd subframe subframe is changed into sub-frame of uplink, the CSI-IM resources that the corresponding CSI-IM resources carried in the 4th subframe are not changed into being carried during sub-frame of uplink with the 3rd subframe are identical resource.

Second, when the descending sub frame of carrying cycle CSI measurement resource is changed into sub-frame of uplink, base station is a set of measurement resource different from cycle CSI measurements resource before of descending sub frame configuration for meeting preset rules, and by signaling terminal；

For example：When the first subframe is changed into sub-frame of uplink, when the corresponding CSI-RS resources carried in the second subframe are not changed into sub-frame of uplink from the first subframe on the CSI-RS that is carried be different resources；Or, when the 3rd subframe subframe is changed into sub-frame of uplink, the CSI-IM resources that the corresponding CSI-IM resources carried in the 4th subframe are carried when not being changed into sub-frame of uplink from the 3rd subframe are different resources.Base station by the second subframe cycle CSI resource allocation informations corresponding with the 4th subframe by signaling by notifying terminal.The signaling that base station is notified can be transferred to UE by physical layer signaling, or high-level signaling, and corresponding signaling can include CSI-RS and CSI-IM resource allocation informations.

The third, when the descending sub frame for carrying cycle CSI measurement resources is changed into sub-frame of uplink, base station is many set cycle CSI measurement resources of descending sub frame configuration for meeting preset rules, this many set CSI measurement resource It can include and cycle CSI measurement resource identical measurement resources before, the measurement resources different from cycle CSI measurements resource before can also be included, base station is by signaling specific CSI-RSs and CSI-IM resource distribution of the UE in the second subframe and the 4th subframe.The signaling that base station is notified can be transferred to UE by physical layer signaling, or high-level signaling, and corresponding signaling can include CSI-RS and CSI-IM resource allocation informations or CSI-RS and CSI-IM resource distribution sequence numbers.
