Embodiment is to make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made belongs to the scope of protection of the invention.
In certain embodiments, it is not specifically described for well known method, interface, equipment signaling technology, in order to avoid because unnecessary details causes the present invention fuzzy.Furthermore, each single functional module is shown in some accompanying drawings.It will be understood to those skilled in the art that these functions can be realized in the following way：Software, application specific integrated circuit (ASIC) and/or the one or more digital signal processors (DSP) of single hardware circuit, the properly programmed digital microprocessor of cooperation or all-purpose computer operation.
Base station in the application is the access network elements in wireless communication system, is not limited to wireless access standard, for example, can be Long Term Evolution（Long term evolution, LTE evolved node B (evolved node B, eNB)) or in senior long term evolution (LTE- Advanced) communication system, can be node B (node B) in 3G communication systems, can also be global system for mobile communications（Global system for mobile communication, GSM) in base transceiver station (base transceiver station, BTS).
At present, base station it should be understood that down channel state just can accurate scheduling radio resources, therefore UE periodic report channel condition informations are needed, even if the content reported twice is same or like, UE remains on needs and reported, this results in the waste of interface-free resources.
In addition, the bandwidth that LTE or lte-a system are supported is very big, single cell is maximum up to 20M.For same UE, in so wide frequency band range, channel status is frequently not identical：For example, the channel status on some frequency bands is preferably, the channel status on some frequency bands is poor.For different UE, because different UE channel status is different, some possible UE are good but poor on frequency band B in frequency band A upper signal channels state；Some UE are good but poor on frequency band A in frequency band B upper signal channels state.To make full use of Radio Resource, UE can be allowed preferentially to use the preferable frequency band of channel status when UE is dispatched, improve system-wide resource efficiency, the scheduling mode of the good frequency band of this preferential use channel status is frequency selection scheduling.At present, in order to support this frequency selection scheduling, UE needs the channel condition information of periodic report different frequency bands, used for eNB.Even if current channel status need not carry out frequency selection scheduling, UE remains on needs and reported, and this results in the waste of interface-free resources.
The embodiment of the present invention takes into full account problem above, and is that, in UE sides, and user is base station in view of the acquisition of downlink channel condition information.If channel condition information is transferred to UE sides using part, so that UE, which is only reported, dispatches useful information for base station resource, the consumption of interface-free resources just can be effectively reduced.For example, UE is after measurement obtains channel condition information, it can be determined that whether channel status needs to carry out whether the demand of frequency selection scheduling or channel status in frequency selection scheduling changes, if, just trigger reporting to base station, and then effectively save interface-free resources.For another example, UE reports the channel condition information of base station after measurement obtains channel condition information, before contrast, when channel state variations are larger, just triggers reporting to base station, and then effectively save interface-free resources.
Whether need to carry out frequency selection scheduling or channel state variations just trigger reporting to base station to which kind of degree on channel status, can be configured in network side previously according to policy requirement, the information configured referred to as preparatory condition（Also referred to as trigger condition）.Certainly, preparatory condition can also be predefined in UE sides, and is stored in UE.And it is different according to the type of channel condition information, the preparatory condition configured is also different.The embodiment of the present invention does not do any limitation.
The state for carrying out frequency selection scheduling is needed to be referred to as have frequency selectivity channel status below, State by channel status without frequency selection scheduling is referred to as without frequency selectivity.Frequency selectivity refers to：In the case that system bandwidth can be divided into multiple sub-bands, the channel status of each sub-band is different, a kind of characteristic that can be scheduled with the good sub-band of prioritizing selection channel status.
In addition, UE to reporting for base station can be configured information, with indicate base station obtain channel condition information；Can also currently measure obtained channel condition information；That is UE can report configured information, can also directly report the channel condition information for currently measuring and obtaining.
The technical scheme in the embodiment of the present invention is clearly and completely described below in conjunction with the accompanying drawings.Fig. 1 is refer to, the flow chart of its a kind of communication means provided by the embodiment of the present invention, as shown in figure 1, this method comprises the following steps：
S110:UE obtains channel condition information；
S120:UE determines whether channel status meets preparatory condition according to the channel condition information of acquisition；When channel status meets preparatory condition, step S130 is performed;Otherwise, UE is not reported.
S130:UE reports configured information or channel condition information to base station.
It can be seen that, in above communication means, UE is after measurement obtains channel condition information, determine whether current channel condition meets preparatory condition according to channel condition information, when meeting preparatory condition just reported to base station, and then can reduce it is unnecessary report, effectively save interface-free resources.
In above step S110, UE obtains channel condition information and realized by channel status measurement, and channel status measurement can include one or more, for example：Frequency selects feature measurement, full bandwidth channel quality to indicate（Channel quality indication, CQI) measurement, pre-coding matrix instruction (recoding matrix indicator, PMI) measurement and the order of channel matrix（The number of RANK, i.e. channel matrix characteristic value）The one or more of measurement etc..In realization, UE can be given tacit consent to and carry out one or more channel status measurements, can also be UE configurating channel state measurement types by network side.Fig. 2 is refer to, if configured by network side, before above step S110, this method also includes：
S100:UE receives the configuration information that base station is sent, and the configuration information includes channel status measurement type.Then in above step S110, further just the blunt channel status according in configuration information is measured UE Type obtains the channel condition information of respective type.
Wherein, the channel status measurement type is included with one of Types Below or its any combination：Frequency selects feature measurement, full bandwidth CQI measurements, PMI measurements and RANK measurements.
In above step S120, preparatory condition is configured previously according to policy requirement, and different according to the type of channel condition information, and the preparatory condition configured is also different.In addition, preparatory condition can be pre-set at network side, UE sides can also be pre-set at, the embodiment of the present invention does not do any limitation.When preparatory condition condition is pre-set at network side, base station can be sent to UE, i.e. configuration information by the configuration information in above step S100 also includes preparatory condition.
In above step S130, the information that UE is reported can be the channel condition information of configured information or acquisition；And the content and form of configured information can be pre-defined.In realization, UE can be given tacit consent to report using this pre-defined content and form.The content and form that configured information is reported can also be pre-defined in network side, the embodiment of the present invention does not do any limitation.When pre-defining the content and form that configured information is reported in network side, base station can be sent to UE by the configuration information in above step S100, i.e. configuration information also includes configured information configuration, and the configured information is configured to indicate that the content and form for the configured information that UE is reported.
Such as pre-defined configured information includes the type information of channel state variations, the class information of channel state variations.In this way, base station can determine the type from the UE channel condition informations obtained according to configured information, so as to reduce reporting for the channel condition information of unnecessary type, interface-free resources are further saved；Base station can also further determine whether to obtain channel condition information from UE, further save interface-free resources according to the grades of channel state variations.
UE can report base station configured information or directly report the channel condition information currently obtained when channel status meets preparatory condition.When UE directly reports the channel condition information currently obtained, the channel condition information that base station can be reported according to UE carries out wireless resource scheduling.When UE reports configured information, base station can judge whether the type for needing to obtain channel condition information and the channel condition information of acquisition according to configured information, unnecessary reporting source of channel state information further be reduced, so as to save more interface-free resources.Corresponding to this, the embodiment of the present invention also provides a kind of flow chart of communication means, such as Fig. 3 Shown, the executive agent of this method is base station, is comprised the following steps：
S310:The channel condition information that the configured information or UE that base station reception UE is reported currently are obtained, the channel condition information that the configured information or UE are currently obtained is just blunt on UE is when channel status meets preparatory condition；
If base station receives the configured information that UE is reported, following steps S320 and S330 are performed;If the channel condition information that the UE that base station reception UE is reported currently is obtained, performs following steps S300.
S320:Base station obtains channel condition information according to configured information from UE；
S330:Base station carries out wireless resource scheduling according to the channel condition information obtained in step S320.
S340:The channel condition information that base station is currently obtained according to the UE received in step S310 carries out wireless resource scheduling.
Information indicated above can include the type information of channel state variations, can also include corresponding to class information of each channel state variations type etc..
When configured information includes the type information of channel state variations, base station can obtain the channel condition information of respective type according to the type information of the channel state variations, further reduce reporting for unnecessary channel condition information, save interface-free resources.For example, the channel condition information that UE is obtained includes CQL PMI, RANK etc.；According to CQI, UE has found that the frequency selectivity of channel status does not change, is still within no frequency selectivity state, but PMI and RANK are changed；For this by configured information by current channel status signals base, know that selectivity of channel frequency does not change by configured information in base station, and PMI and RANK are changed, therefore PMI and RANK information is obtained from UE according to configured information, without obtaining CQI information.In this way, the channel condition information reported needed for UE can be reduced further, interface-free resources are further saved.
When configured information also includes the class information of each channel state variations type of correspondence, base station can preset strategy, when the class information of some channel state variations meets predetermined level requirement, base station just obtains channel condition information corresponding with the channel state variations type information for meeting class requirement from UE.For example, multiple grades are preset in the change for being CQI, and preset when its change reaches some grade and the above just acquisition CQI information.In this way, the channel shape reported needed for UE can be reduced further State information, further saves interface-free resources.
In addition, in above step S310, whether channel status, which meets preparatory condition, is judged by the UE channel condition informations obtained according to measurement.The channel condition information measurement which type UE carries out can be configured by network side, and be sent to UE by base station.Fig. 4 is refer to, if configured by network side, before above step S310, this method also includes：
S300:Base station is to UE send configuration information, the configuration information includes channel status measurement type, the channel status measurement type is used for the channel condition information for indicating that UE obtains respective type, to determine whether channel status meets preparatory condition according to the channel condition information of acquisition.
With Fig. 2 illustrated embodiments, the channel status measurement type is included with one of Types Below or its any combination：Frequency selects feature measurement, full bandwidth CQI measurements, PMI measurements and RANK measurements.And, the configuration information can also include preparatory condition, can also include configured information configuration.It will not be repeated here.
In above step S300, base station can control cell by RRC signaling or media access control layer（MAC control element, MAC CE) to UE send configuration information.For example, existing RRC signaling can be extended（For example, RRC reconfigures signaling), new RRC signaling can also be increased or new MAC CE are defined;So as to which preparatory condition is notified into UE by RRC signaling or MAC CE.
Above channel condition information can include one of following information or its any combination：CQI, signal and perturbed force mouthful noise ratio（Signal to interference plus noise ratio, SINR), PMI and RANK etc..The embodiment of the present invention does not do any limitation.
In one embodiment, a kind of MAC CE can be defined, information indicated above is used as.The effect of the MAC CE is the situation of signals base channel state variations, in order to which base station can determine the need for further obtaining detailed channel condition information according to the configured information.Certainly, can be embodied when channel state variations by different information, for change information notice can simply can also be increasingly complex, can specifically be realized by the definition to MAC CE.
For example, the mark that the head that can define MAC CE is MAC CE（), ID and by the length of loading section it is set to " 0 ";Now, the MAC CE are used to trigger the channel shapes that base station obtains whole State information.MAC CE load can be done to the definition of different the level of details, to reflect the substantially situation of channel state variations, if the situation that base station is reflected according to MAC CE, judgement needs further to obtain more detailed channel condition information, then triggers UE reporting status information of channel.For example, MAC CE loading section can include the type information of channel state variations（Hereinafter referred to as type information）Or the class information of channel state variations（Hereinafter referred to as class information）, can also both include type information or including class information；Wherein type information indicates the type of channel state variations, and class information indicates the degree of channel state variations.And both included type information or during including class information in configured information, the corresponding relation of type information and class information can be set.
In order to which the definition to the MAC CE is more clear understandable, table 1 gives a specific example,
As it can be seen from table 1 the loading section of the MAC CE includes type information（It is low 3）And class information（It is high 5）.Wherein, type information can include selecting characteristic, full bandwidth CQI, PMI and RANK frequently;Wherein reserved bit can be in order to extending more type informations later.For example, when low 3 values are " 0 ", showing that channel status selects characteristic variations to be to have frequency to select characteristic from without frequency, now base station can judge that channel has frequency to select characteristic according to the information, so as to trigger UE reporting status information of channel.When low 3 be value be " 1 " when, show channel status from have frequency select characteristic variations be without frequency select characteristic, Herein, base station can judge that channel selects characteristic without frequency according to the information, without UE reporting status information of channel.It is other similar therewith, when it is " 4 " that low 3, which are value, RANK changes, then base station can trigger UE reporting status information of channel accordingly.Class information can include multiple grades, can specifically be configured in network side previously according to policy requirement.
It should be noted that table 1 is example, it is not intended to limit the present invention.Definition on MAC CE can have multiple combinations mode.For example, for the channel condition information of each type a MAC CE can be set respectively, now only need to increase type identification；The channel condition information of multiple types can be arranged in a MAC CE such as table 1；One MAC CE can also be set for certain form of channel condition information, and the channel condition information of other types is set sets a MAC CE again;The embodiment of the present invention does not do any limitation.For another example, MAC CE loading section can only include type information or class information, and type information and class information can also be included simultaneously（As shown in table 1）.In addition, also not Limit Type information and the digit shared by class information and position of the embodiment of the present invention, such as MAC CE payload length is m (m is positive integer), and type information can be located at low n（N is the positive integer less than or equal to m）, class information can be located at high m-n；Or class information can be located at it is low n（N is the positive integer less than or equal to m）, type information can be located at high m-n.In addition, also not doing any limitation for reserved bit, reserved bit can be reserved, can not also be reserved, reserved digit can also arbitrarily be set as needed.In a word, any limitation is not done in definition of the present invention to MAC CE loading sections.
In addition, reporting mechanism to be set in advance in network side on UE, and UE is sent to by base station.For example, network side can pre-set preparatory condition, and UE reports configured information or directly reporting status information of channel when meeting preparatory condition.If default UE reports configured information, configured information reports content and form in advance to be pre-set in network side, for example, realizing above MAC CE configuration in network side.Certainly, network side is also required to as the type of UE configurating channel state measurements, and such UE can accordingly be measured according to the type of configuration, get corresponding channel condition information.The measurement type of possible configuration has：Frequency selects feature measurement, full bandwidth CQI measurements, PMI measurements, RANK measurements and this several any combination, furthermore, it is possible to configure these measurements simultaneously The startup and stopping of type, can also each measurement type of separate configurations startup and stopping.
On reporting the definition of mechanism to be adjusted according to the policy requirement of network operation, the embodiment of the present invention does not do any limitation.Several possible configuring conditions given below, but it is only for example, and is not intended to limit the present invention.
Firstth, characteristic is selected to frequency, sub-band division and preparatory condition can be pre-configured with.Sub-band division can also define new sub-band, the embodiment of the present invention does not do any limitation using current common sub-band division mode.Preparatory condition can be by setting wealthy value to embody, for example, wealthy value 1 or wealthy value 2 (the two wealthy values can be with identical or different) are set, if the CQI variances on each sub-band exceed wealthy value 1, then illustrate that current channel condition has frequency selectivity, UE can be triggered and reported；CQI variances on such as each sub-band are less than wealthy value 2, then illustrate current channel condition without frequency selectivity, can also trigger UE and report；To notify the change of BTS channel state, so as to change of the base station according to channel status, decide whether to obtain channel condition information.In addition, the condition that triggering UE is reported above can also include the situation equal to wealthy value.Here variance, which is calculated, otherwise for example to count judging except using CQI as that according in addition to, foundation can also be measured as with other channel condition informations, for example, calculating variance with the SINR of each sub-band for frequency selectivity.
By taking the configured information MAC CE shown in table 1 as an example, if the CQI variances on each sub-band exceed wealthy value 1, illustrate that current channel condition has frequency selectivity, now configured information MAC CE low 3 values are " 0 ".Class information can be not provided with（It is high 5）, the configured information is reported into base station, base station is just known that the type of channel state variations, so as to obtain the channel condition information of respective type according to the type.Likewise, when the CQI variances on each sub-band are less than wealthy value 2, then illustrating current channel condition without frequency selectivity, now configured information MAC CE low 3 values are " 1 ".The configured information is reported into base station, base station is just known that channel state variations are without frequency selectivity, so as to obtain channel condition information.
It is of course also possible to set class information, such as it is 0 to 15 according to CQI value, is divided into multiple grades, exemplified by 3,0 to 5 is a grade, and 5 to 10 be a grade, and 10 arrive 15 be a grade, and this class information is reported into base station, and such base station can preset strategy, when the change of channel status reaches at or above grade 2, just obtains corresponding channel condition information from UE.On the division of grade, citing is these are only, the grade of 2 or more can be divided, and grade classification is divided also without equispaced（It these are only simple declaration）, for example, can be divided into a grade by 1 to 6,7 to 9 be divided into a grade, 10 to 15 be divided into a grade, this is similar to the grain size category that current CQI is reported.
Secondth, full bandwidth CQI is changed, defines the wealthy value of series of CQI changes, triggered and report if variable quantity exceedes wealthy value.CQI contrast benchmark can the last time report value, can also be in the signaling（Such as above-described configuration information）Clearly configure.
By taking the configured information MAC CE shown in table 1 as an example, if full bandwidth CQI changes, now the type information value of the MAC CE is 2, and class information is determined according to the wealthy value of the series reached.
The configured information is reported base station by UE, and base station is just known that the grade of full bandwidth CQI changes, and decides whether to obtain full bandwidth CQI information accordingly.
3rd, PMI changes and RANK are changed, changes i.e. triggering and report, can be without defining wealthy value.It can the last time report value to contrast benchmark, can also be in signaling（Such as above-described configuration information）In clearly configure.
