Description

Cell measurement method, device and communication system

The application is a divisional application of an invention patent application with the application date of 2014, 05 and 09 and the application number of 201480078366.9, and the invention is named as a cell measurement method, a cell measurement device and a communication system.

Technical Field

The present invention relates to the field of communications, and in particular, to a cell measurement method, an apparatus, and a communication system.

Background

In future mobile communication, in order to ensure coverage and reasonably adjust service requirements and equipment overhead, a Heterogeneous deployment (Heterogeneous deployment) scenario in which a macro cell (macro cell) and a small cell (small cell) coexist will become one of the main deployment scenarios of a mobile communication system. The macro cell is responsible for coverage of users, and the small cell is responsible for data offloading (offloading) of users. Typical small cells include micro cells, femtocells and femtocells. The transmission power of the macrocell base station is relatively large compared to that of the small cell. Accordingly, Power Amplifiers (PA) and Radio Frequency units (RF) of the macrocell base station consume a large amount of Power, and thus some air conditioners are required to maintain normal operation of the base station. The Energy Efficiency (EE) of a macro cell base station is significantly lower than that of a small cell. Small cells have significant advantages in energy saving and flexible deployment.

In general, the number of users served by each macro cell is large, so the total number of users and the total uplink and downlink services of the whole cell tend to be stable as a whole. The coverage area of the small cell is small, and the number of users served by each small cell at the same time is far smaller than that of the users of the macro cell. Dynamic changes of users within a small cell, such as users joining or leaving a small cell, are also very fast. This relatively fast dynamic change of small cells may result in an uneven distribution of the number of users and the data demand among the individual small cells. For example, when one small cell is operating at full load, the neighboring small cells may be in a low-load or even idle state.

In order to save energy and reduce inter-cell interference when small cells are densely distributed, a method for dynamically switching small cells is introduced into the Long Term Evolution (LTE) standard. This method of dynamically switching small cells is based on a mechanism where cells are turned on or off quickly. When there is no UE needing to be served in a small cell or when a small cell and its surrounding small cells are all in a low load condition, it may be considered to switch the current user served by the small cell to a neighboring small cell, and then switch off the small cell. When a new user arrives in a closed small cell, or a new packet arrives from an existing user in its coverage area, or other events occur that meet the small cell open conditions, the small cell is opened to serve the new user or to offload large packet transmissions, etc.

In order to improve the system transmission efficiency, a user should find enough small cells as quickly as possible and accurately measure the small cells, so that the user can be quickly started to be served by the evaluated small cells when there is a need. Therefore, how to enable the user to quickly find and accurately measure the small cell is one of the main problems to be solved in the release 12 of the LTE system.

It should be noted that the above background description is only for the sake of clarity and complete description of the technical solutions of the present invention and for the understanding of those skilled in the art. Such solutions are not considered to be known to the person skilled in the art merely because they have been set forth in the background section of the invention.

Detailed Description

The foregoing and other features of the invention will become apparent from the following description taken in conjunction with the accompanying drawings. In the description and drawings, particular embodiments of the invention have been disclosed in detail as being indicative of some of the embodiments in which the principles of the invention may be employed, it being understood that the invention is not limited to the embodiments described, but, on the contrary, is intended to cover all modifications, variations, and equivalents falling within the scope of the appended claims. Various embodiments of the present invention will be described below with reference to the accompanying drawings. These embodiments are merely exemplary and are not intended to limit the present invention.

In the discussion of discovery signals for small cells, a better choice is to use existing signals to achieve cell discovery and measurement. Therefore, the existing signal processing flow can be utilized, and the original software and hardware design scheme is reused as much as possible to simplify the product design of a new version system.

In the conventional signals, the original Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS), Common Reference Signal (CRS), Channel State Information Reference Signal (CSI-RS), and Positioning Reference Signal (PRS) may become candidates for the small cell discovery Signal. However, it may be difficult for only any one of the signals to meet cell discovery and cell measurement requirements in all small cell deployment scenarios, such as probability of correctly discovering a cell and accuracy of cell measurements. The discovery signal of the small cell may be composed of one or more of the above signals. In the process of cell discovery, the correlation probability obtained by matching one signal with the correlation probability obtained by matching another signal are easily combined, for example, the PSS and SSS signals are simultaneously used in the existing cell discovery. However, in existing signal transmission and reception schemes, one measurement is usually done based on only one signal. For example, RRM (Radio Resource Management) measurement may be performed based on an Orthogonal Frequency Division Multiplexing (OFDM) symbol including CRS, or CSI (Channel state information) measurement may be performed based on an OFDM symbol including CSI-RS. If the discovery signal of a small cell consists of multiple different types of signals, e.g. jointly PSS/SSS/CRS/CSI-RS, it may be a waste to perform one measurement with only one signal. However, since the transmission energy of the various signals may be different, different measurement results may not be able to be combined directly when the same measurement is made based on different signals.

To solve this problem, embodiments of the present invention provide a solution that can simultaneously perform the same measurement using different signals, and improve the accuracy of the measurement by combining the measurement results.

The following describes a cell measurement method, a cell measurement device, and a communication system according to embodiments of the present invention in detail with reference to the accompanying drawings.

Example 1

An embodiment of the present invention provides a cell measurement method, where fig. 1 is a flowchart of the method, and please refer to fig. 1, the method includes:

step 101: the user equipment measures the received signal of the cell to be measured by utilizing at least one signal of at least two different types of signals of the cell to be measured; wherein one of the at least two different types of signals is a standard signal that is used as a reference when adjusting the measurement results.

In this embodiment, the measurement content for performing the measurement may be signal quality, that is, the user equipment measures the received signal quality of the signal of the cell to be measured. The received signal quality may be expressed as one or more of a received reference signal energy, or a received signal to noise ratio, or a received signal to interference ratio, or a total energy of an interfering signal and noise in the received signal, or a total energy of the received reference signal and the interfering signal and noise. The Received Reference Signal energy may be represented as RSRP, the total energy of the Received Reference Signal, the interference Signal and the noise may be represented as Received Signal Strength Indication (RSSI), and the Signal Quality may be directly represented as Reference Signal Receiving Quality (RSRQ), but the embodiment is not limited thereto.

In an embodiment of this embodiment, a base station (serving base station) of a serving cell of the user equipment may configure the user equipment to perform the measurement, where the configuration may be performed for the serving base station or a frequency point where the serving base station is located, so that the user equipment may perform the measurement according to the configuration of the serving base station. For example, the serving base station sends configuration information for performing the measurement to the user equipment through a control signaling, where the configuration information may include who the cell to be measured needs to be measured is, and may also include which of at least two different types of signals of the cell to be measured that can be used for performing the measurement is.

In this embodiment, the user equipment may select at least one of the at least two different types of signals to perform the measurement in each measurement according to the signal observed from the observation window. The selected signals may be the same or different for each measurement, and the selected signals may or may not include the standard signals.

For example, at least two different types of signals of the cell to be measured included in the configuration information are CRS/CSI-RS, and the user equipment may perform RRM measurement (for example, Reference Signal Receiving Power (RSRP) measurement therein) or CSI measurement (for example, Signal energy therein) on the cell to be measured by using the CRS signals and the CSI-RS signals at the same time.

In this embodiment, the standard signal is used as a reference for adjusting the measurement result, that is, the ue may adjust the measurement result of another signal with reference to the measurement result of the standard signal when adjusting the measurement result, which of the at least two different types of signals is used as the standard signal may be predetermined by the ue and a serving base station of the ue in advance, for example, a CRS signal is used as the standard signal for measurement in all cases; the serving base station of the ue may also configure the ue, for example, information about which signal is used as a standard signal is included in the configuration information, for example, configure a CRS or a CSI-RS as the standard signal for the current measurement; it may also be default, e.g. to CRS if options on the standard signal are missing in the configuration information, etc.

In an implementation manner of this embodiment, the method may further include:

step 102: the user equipment adjusts the measurement results of the signals except the standard signal in the at least two different types of signals into the measurement results equivalent to the measurement results of the standard signal.

In the present embodiment, the measurement result of the standard signal may be obtained by actually measuring the standard signal (actually measured) or may be obtained by assuming that the standard signal is measured (assumed).

In this embodiment, the at least two different types of signals may be sent by the cell to be tested on different time-frequency resources, for example, the signals may be sent on a common frequency domain position in different periods and/or time-domain patterns, and so on. Moreover, the cell to be measured may be a serving cell of the user equipment or an adjacent cell of the user equipment.

In an embodiment of this embodiment, if the cell to be measured is a serving cell of the ue, and the ue knows actual transmission time-frequency positions and actual transmission powers of the at least two different types of signals transmitted by a base station (serving base station) of the cell to be measured, only part of the at least two different types of signals may be transmitted in an observation window of a single measurement, that is, the ue may observe part of the at least two different types of signals of the cell to be measured in the observation window of a single measurement. Thus, the user equipment may select one or more of the transmitted signals to make the measurement in a single measurement, e.g., if a signal is observed, the measurement is made on the observed signal without selection; if more than one, for example two or more (referred to as multiple), are observed, the signal to be measured can be selected therefrom and the measurement can be performed on the selected signal.

Since the base station of the cell to be measured may use different powers when transmitting the at least two different types of signals, the measurement results respectively measured based on the at least two types of signals may not be directly combined, or the measurement results measured based on only one or more non-standard signals may not be directly reported. In this case, after the measurement based on each signal is completed, the ue may adjust the measurement results of all signals except the standard signal, which have been measured, to the measurement results corresponding to the measurement results of the standard signal, using the transmission power information, for example, the power ratio, of the at least two different types of signals, which has been obtained.

Optionally, if the ue uses two or more signals to perform the above measurement, after the adjustment of the measurement result is completed, the ue may also combine the measurement results, where the measurement result may be adjusted or may not be adjusted (for example, the standard signal itself), so as to obtain the final measurement result of the measurement. The merging algorithm is not limited here and may be, for example, an arithmetic mean or a moving mean. Moreover, the user equipment may also combine the results of multiple measurements, which is not described herein again.

For example, it is assumed that the at least two different types of signals are CRS and CSI-RS, wherein the standard signal is CRS. The base station of the cell to be measured may adopt different powers when sending the CRS and the CSI-RS, and the user equipment knows that the power of sending the CRS and the power of sending the CSI-RS by the base station are 2: 1. If the user equipment simultaneously and respectively adopts CRS and CSI-RS to measure and send signal energy, the measured results are respectively 0.9 and 0.4. Then the adjusted CRS-based and CSI-RS measurements are 0.9 and 0.8, respectively. The combined measurements were 0.85 by arithmetic mean.

In another embodiment of this embodiment, if the cell to be measured is a serving cell or an adjacent cell of the ue, the ue may observe at least two different types of signals of the same cell to be measured in an observation window of each measurement, that is, the ue may observe all signals of the at least two different types of signals of the cell to be measured in an observation window of a single measurement. As mentioned above, the user equipment may select one or more of the at least two different types of signals for the measurement in each measurement, the selected signals may be the same or different in each measurement, and the selected signals may or may not include standard signals. Therefore, the user equipment adjusts and/or combines the measurement results obtained based on different reference signals, and the measurement accuracy can be improved. And, if the user equipment observes a signal in the observation window, the user equipment can perform the above measurement on the observed signal without performing selection; if the user equipment observes a plurality of signals in the observation window, the user equipment can select signals for measurement from the observed plurality of signals, and perform the measurement on the selected signals.

If the cell to be measured is the serving cell of the ue, as described above, when the measurement result needs to be adjusted, the ue may directly obtain the transmit power information of the at least two different types of signals sent by the serving cell, so as to complete the adjustment. The adjustment method and the combination method are as described above, and the description thereof is omitted here.

If the cell to be measured is the neighboring cell of the ue, as described above, when the measurement result needs to be adjusted, the base station of the serving cell of the ue may configure, to the ue, power information of all possible signals of the neighboring cell (a specific configuration method will be described in the following embodiments), for example, relative power, that is, power relative to a standard signal, to the ue. The ue first receives the information of the transmission powers of the at least two different types of signals of the cell to be measured, which is sent by the base station of its serving cell, and then adjusts the measurement result of the selected signal accordingly. Optionally, the measurement results (including the adjusted measurement results) may be combined to obtain a final measurement result. The adjustment method and the combination method are as described above, and the description thereof is omitted here.

In an implementation manner of this embodiment, after obtaining the measurement result, the method may further include:

step 103: and the user equipment reports the measurement result to a base station of a service cell of the user equipment.

The ue may report the measurement result periodically or by event triggering. For example, for the case of periodic reporting, the base station may configure the ue to report the measurement result periodically, and then a timer is set inside the ue, and when the timer expires, the ue reports a measurement result. For another example, for the event triggering case, if the measurement result meets some conditions, the ue is triggered to report the measurement result.

In addition, the ue may report the measurement result and also report signals on which its measurement is based. In this case, the reported results may be combined, or the results may be obtained based on each signal. Also, the results obtained based on the non-standard signals may be adjusted or unadjusted, but the user equipment and base station should have consistent understanding (and may agree on being configurable) as to whether or not adjustments have been made. For example, by reporting "CRS: 0.9; CSI-RS: 0.4 "indicates that the measurement result based on the CRS is 0.9, the measurement result based on the CSI-RS is 0.4, wherein the standard signal is the CRS, and the reported measurement results are unadjusted and not combined.

In this embodiment, when the base station determines that the ue does not need to adjust the measurement result, for example, the base station configures or pre-stipulates that the ue can report the result for different signals, and the base station may not configure the power information of all signals that the ue may use for the ue.

By the method of the embodiment, the user equipment can perform the same measurement by using different signals, in addition, the measurement results of other signals are adjusted by referring to the measurement result of the standard signal, and then the measurement results are combined, so that the measurement precision is further improved.

Example 2

An embodiment of the present invention further provides a cell measurement method, which is a processing on a base station side of a serving cell of a user equipment corresponding to the method in embodiment 1, where the same contents as those in embodiment 1 are not described again. Fig. 2 is a flowchart of the method, please refer to fig. 2, which includes:

step 201: the base station of the service cell of the user equipment configures the user equipment to measure the received signal of the cell to be measured by using at least one signal of at least two different types of signals of the cell to be measured, wherein one signal of the at least two different types of signals is a standard signal used as a reference when a measurement result is adjusted.

In this embodiment, the configuration of the base station, the cell to be tested, the at least two different types of signals, and the standard signal thereof have been described in detail in embodiment 1, and the contents thereof are incorporated herein and will not be described again.

In an implementation of this embodiment, the method further comprises:

step 202: and the base station sends the information of the sending power of the signals of the at least two different types of the cell to be measured to the user equipment, so that the user equipment can adjust the measurement results of other signals except the standard signal in the signals to be measured according to the measurement result of the standard signal.

If the cell to be tested is the service cell of the user equipment, the base station directly sends the information of the sending power of the signals of at least two different types sent by the base station to the user equipment.

If the cell to be tested is the adjacent cell of the user equipment, the base station receives the information of the transmission power of the signals of at least two different types of the adjacent cell from the base station of the adjacent cell, and then sends the information to the user equipment served by the base station.

In an implementation manner of this embodiment, the base station may further configure a reporting manner and a reporting form of the ue for the measurement result, for example, whether the measurement result is reported periodically or triggered by an event, whether the measurement result is reported after being adjusted and combined or without being adjusted and combined, whether the measurement result is based on a signal or only the measurement result is reported at the same time, and the like.

If the base station determines that the ue does not need to adjust the measurement result, for example, the ue may report the measurement result for different signals, respectively, the base station may not configure the power information of the signal that the ue may use for the ue.

In an embodiment of this embodiment, the base station may further configure its discovery signal for the neighboring cell, for example, which signals are included, and optionally, may further configure an absolute transmission power or a ratio of relative transmission powers of these signals for the neighboring cell, so that the neighboring cell may determine the discovery signal and the related power information used by itself accordingly. The embodiment can be applied to the case that the macro cell configures the cells covered by the macro cell for the purpose of interference coordination.

The neighboring cell is used as the serving cell of the ue in embodiments 1 and 2, and the measurement may be configured for the ue according to the method in embodiment 2, so that the ue measures the cell in this embodiment, and sends information of the transmission powers of at least two different types of signals of the cell (cell to be measured) in this embodiment to the ue, so that the ue adjusts the measurement results of other signals except the standard signal in the signals to be measured according to the measurement result of the standard signal.
