Referring to the drawings, by following specification, foregoing and further feature of the invention will be apparent.In the specification and illustrated in the drawings, only certain exemplary embodiments of this invention is specifically disclosed, which show wherein can be using original of the invention
Some embodiments then, it will thus be appreciated that the invention is not restricted to described embodiment, on the contrary, the present invention includes whole modifications, modification and the equivalent fallen within the scope of the appended claims.The various embodiments to the present invention are illustrated below in conjunction with the accompanying drawings.These embodiments are exemplary, are not limitations of the present invention.
In the discussion for the discovery signal of cell, a kind of relatively good selection is to utilize existing signal, goes to realize the discovery of cell and measurement.So, it is possible to use existing signal processing flow, so as to reuse original soft and hardware design as far as possible to simplify the product design of new version system.
In existing signal, due to original master sync signal（Primary Synchronous Signal, PSS) I auxiliary synchronous signals (Secondary Synchronous Signal, SSS), public reference signal (Common Reference Signal, CRS), channel state information reference signals (Channel State Information Reference Signal, CSI-RS) and location reference signals（Positioning Reference Signal, PRS) all it is likely to become the candidate signal that cell finds signal.But, any one signal only therein may be difficult that the cell met in all cell deployment scenarios is found and cell measurement requirements, such as the correct probability and the precision to cell measurement for finding cell.The discovery signal of cell, can be made up of the one or more in above-mentioned signal.During cell discovery is carried out, the dependent probability that dependent probability and another signal after being matched using a kind of signal are obtained after matching is easy to merge, such as existing cell is carried out using PSS and SSS signals simultaneously in finding.But, existing signal is sent and received in scheme, and one kind measurement is generally based only upon a kind of signal and completed.For example, can be based on containing
CRS OFDM（Orthogonal Frequency Division Multiplexing, OFDM) symbol progress RRM（Radio Resource Management, RRM) measurement, or channel condition information is carried out based on the OFDM symbol containing CSI-RS（Channel State Information, CSI) measurement.If the discovery signal of cell is made up of a variety of different types of signals, for example, collectively constituted by PSS/SSS/CRS/CSI-RS, it is probably a kind of waste to carry out a kind of measurement just with a kind of signal.But, because the transmission energy of various signals may be different, therefore, when carrying out same measurement based on unlike signal, different measurement results may not directly merge.
In order to solve this problem, the embodiments of the invention provide a solution, the program can carry out same measurement using unlike signal simultaneously, and improve the precision measured by merging measurement result.
The cell measuring method, device and communication system of the embodiment of the present invention are described in detail below in conjunction with the accompanying drawings.Embodiment 1
The embodiments of the invention provide a kind of cell measuring method, Fig. 1 is the flow chart of this method, refer to Fig. 1, and this method includes：
Step 101:User equipment is measured using at least one of at least two different types of signals of cell to be measured signal, the signal of the cell to be measured to receiving；Wherein, the standard signal of reference is used as when the one of which signal at least two different types of signal is adjustment measurement result.
In the present embodiment, the measurement content for carrying out above-mentioned measurement can be signal quality, namely user equipment is measured to the received signal quality of the signal of the cell to be measured received.Received signal quality can show as the one or more for receiving reference signal energy or snr of received signal or receiving in signal letter drying ratio or reception signal among the gross energy of interference signal and noise gross energy or reception reference signal and interference signal and noise.Wherein, RSRP can be shown as by receiving reference signal energy, and the gross energy for receiving reference signal and interference signal and noise can behave as received signal strength indicator（Received Signal Strength Indication, RSSI), signal quality can directly translate into Reference Signal Received Quality（Reference Signal Receiving Quality, RSRQ), but the present embodiment is not in this, as limitation.
In an embodiment of the present embodiment, the base station of the serving cell of the user equipment（Serving BS）The user equipment can be configured and carry out above-mentioned measurement, the configuration can be carried out for serving BS or carried out for the frequency where serving BS, thus, and user equipment can carry out above-mentioned measurement according to the configuration of its serving BS.For example, the serving BS sends the configuration information for carrying out above-mentioned measurement by control signaling to the user equipment, comprising the cell to be measured for needing to measure whom can be in the configuration information, which can also there is comprising at least two different types of signals of the cell to be measured that can be used for measuring.
In the present embodiment, user equipment is in each measurement, according to the signal observed from watch window, and at least one of above-mentioned at least two different types of signals can be selected to carry out above-mentioned measurement.Wherein, selected signal is measured every time can be the same or different, also, can not can also include standard signal comprising standard signal in selected signal.
For example, at least two different types of signals of the cell to be measured included in the configuration information are CRS/CSI-RS, then user equipment can carry out RRM measurements using CRS signals and CSI-RS signals to cell to be measured simultaneously（Such as Reference Signal Received Power therein（Reference Signal Receiving Power, RSRP) measurement）Or carry out CSI measurements（Such as signal energy therein）.
In the present embodiment, standard signal is as a reference to the adjustment for measuring result is used, namely, user equipment may be referred to the measurement result of the standard signal to adjust the measurement result of other signals when adjusting measurement result, then it regard any in above-mentioned at least two different types of signals as above-mentioned standard signal, can the serving BS of the user equipment and the user equipment arrange in advance, for example, being all used as survey using CRS signals under all situations
The standard signal of amount；The serving BS that can also be the user equipment is the user device configuration, for example, the information using any signal as standard signal is contained in aforementioned arrangements information, for example, the standard signal that configuration CRS or CSI-RS is measured as this；Acquiescence is can also be, for example, default standard signal is CRS, etc. if the default option on standard signal in configuration information.
In an embodiment of the present embodiment, this method can also include：
Step 102:The user equipment is by the measurement result of other signals is adjusted to the measurement result suitable with the measurement result of the standard signal in addition to standard signal at least two different types of signal.
In the present embodiment, the measurement result of standard signal can actually be measured the standard signal and obtain (actually measured）Or assume to measure the standard signal and obtain（It is assumed that）.
In the present embodiment, at least two different types of signal can be transmitted by the cell to be measured on different running time-frequency resources, and such as these signals can be sent with different cycles and/or time domain pattern on common frequency domain position, etc..Also, the cell to be measured can be serving cell or the neighbor cell of user equipment of user equipment.
In an embodiment of the present embodiment, if cell to be measured is the serving cell of the user equipment, the base station of cell to be measured known to the user equipment（Serving BS）The actual transmission time-frequency location and actual transmission power of the transmitted at least two different types of signal, then in the watch window of single measurement, above-mentioned at least two different types of signal only may be sent part, that is, user equipment may observe the part signal at least two different types of signal of the cell to be measured in the watch window of single measurement.Therefore, user equipment is in single measurement, can select one or more than one kinds of above-mentioned measurements of carry out in the signal that is sent, for example, if it is observed that a kind of signal, then pair signal observed carries out above-mentioned measurement, without selection；If it is observed that more than one, for example two or more（It is referred to as a variety of）, then the signal for needing to measure can be therefrom selected, and above-mentioned measurement is carried out to the signal selected.
Wherein, because the base station of cell to be measured may use different capacity when sending above-mentioned at least two different types of signal, therefore being based respectively on the measurement result that this at least two signal measures to be likely to directly to merge, or be based only upon the measurement result that one of which or a variety of non-standard signals measure directly to report.Now, after the measurement based on each signal terminates, user equipment can utilize the power information of above-mentioned at least two obtained different types of signals, such as power ratio, the measurement result that will carry out other all signals in addition to standard signal of above-mentioned measurement is adjusted to the measurement result suitable with the measurement result of standard signal.

For example, it is assumed that above-mentioned at least two different types of signal is CRS and CSI-RS, wherein, standard signal is
CRS.Then the base station of cell to be measured may use different capacity when sending CRS and CSI-RS, also, it is 2 that user equipment known base station, which sends CRS power and CSI-RS power,:1.If CRS and CSI-RS is respectively adopted in user equipment simultaneously, measurement sends signal energy, and the result measured is respectively 0.9 and 0.4.After so adjusting is respectively 0.9 and 0.8 based on CRS and CSI-RS measurement results.By arithmetic average, the measurement result after merging is 0.85.
In another embodiment of the present embodiment, if cell to be measured is serving cell or the neighbor cell of the user equipment, user equipment can observe that at least two different types of signals of the identical cell to be measured, namely user equipment can observe all signals at least two different types of signal of the cell to be measured in the watch window of single measurement in the watch window measured every time.Then as previously described, user equipment can be in each measurement, select one or more than one kinds of above-mentioned measurements of carry out in above-mentioned at least two different types of signals, selected signal is measured every time to can be the same or different, selected signal can include standard signal, can also not include standard signal.Thus, user equipment will be adjusted and/or be merged based on the measurement result obtained by different reference signals, can improve measurement accuracy.Also, if user equipment observes a kind of signal in watch window, then the user equipment can pair signal observed carry out above-mentioned measurement, without being selected again；If user equipment observes multi-signal in watch window, the user equipment can be selected to be used to carry out the measurement signal from the multi-signal observed, above-mentioned measurement is carried out to the signal selected.
Wherein, if cell to be measured is the serving cell of the user equipment, then as previously described, when needing adjustment measurement result, user equipment can directly obtain the power information that its serving cell sends above-mentioned at least two different types of signal, thus above-mentioned adjustment is completed, optionally, can also be to measurement result（Including the measurement result after adjustment）Merge, and then obtain final measurement result.Wherein, adjustment mode and merging mode are as it was previously stated, in this description will be omitted.

The information of the transmit power of the above-mentioned at least two different types of signals in area, then adjust accordingly its to it is selected go out signal measurement result.Optionally, can also be to measurement result（Including the measurement result after adjustment）Merge, and then obtain final measurement result.Wherein, adjustment mode and merging mode are as it was previously stated, in this description will be omitted.
In an embodiment of the present embodiment, obtain after measurement result, this method can also include：Step 103:Base station report measurement results from the user equipment to its serving cell.
Wherein, user equipment periodically can also trigger report measurement results by report measurement results by event.For example, when periodicity is reported, base station can configure user equipment periodic report measurement result, then user equipment is internally provided with a timer, when the timer expired, and user equipment just reports one-shot measurement result.In another example, when event is triggered, if measurement result meets some conditions, trigger user equipment to report measurement result.
In addition, user equipment can also report which signal its measurement is based on while report measurement results.In this case, the result reported can be after merging or be based respectively on each signal and obtain result.Also, the result obtained based on non-standard signal can be that to be adjusted can also be unjustified, but user equipment and base station are for whether to carry out the understanding of adjustment should be consistent（It can arrange to configure）.For example, by reporting " CRS: 0.9； CSI-RS:0.4 " it is 0.9 to show the measurement result based on CRS, and the measurement result based on CSI-RS is 0.4, wherein, standard signal is CRS, and the measurement result reported is unjustified, and do not merged.
In the present embodiment, when base station confirms that user equipment need not measure result adjustment, such as base station, which is configured with or arranged in advance user equipment, can be directed to unlike signal reported result respectively, base station can not to user device configuration its all signal that may be used power information.
