technical field

The present invention relates to the field of communication technology, in particular to a measurement method for a cell of a new carrier type, user equipment and a base station.

Background technique

In a long-term evolution (Long Time Evolution; hereinafter referred to as: LTE) system, a new carrier type (New Carrier Type; hereinafter referred to as: NCT) cell may be configured under a traditional macro cell. The NCT cell can independently complete signaling interaction with a user equipment (User Equipment; hereinafter referred to as: UE), without relying on a macro cell. At the same time, the NCT cell can be a kind of discretely distributed cell, that is, it only serves hot spots within a certain range. In this area, if the UE is in a hotspot area that can be covered by NCT cells, it can access NCT cells to be served; if it is in a non-hotspot area that cannot be covered by NCT cells, it can access traditional macro cells to get services.

The NCT cell saves frequency domain resources by reducing the number of pilots; and when there are no or few UEs under the coverage of the NCT cell to be served, it can go to sleep, saving energy consumption on the network side. Due to these advantages, the NCT cell has become a new deployment scheme suitable for communication in hotspot areas.

In the prior art, the downlink pilot of the NCT cell is sent in a discontinuous transmission (Discontinuous Transmission; hereinafter referred to as: DTX) mode, that is, the NCT cell sends the downlink pilot periodically or according to a certain pattern. Therefore, when the UE approaches or enters the NCT cell, unnecessary detection or measurement may be performed, resulting in waste of power of the UE.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is the flow chart of an embodiment of the measurement method of new carrier type sub-district of the present invention, as shown in Fig. 1, the measurement method of this NCT sub-district may comprise:

In step 101, the UE receives DTX mode information sent by a serving base station of the UE, where the DTX mode information is the DTX mode information of a neighboring NCT cell of the serving cell where the UE is located.

In this embodiment, the above DTX mode information includes one or a combination of the following information: sending time information of the downlink pilot and time-frequency position information of the downlink pilot.

Specifically, the UE receives the DTX mode information sent by the serving base station of the UE as: when the UE is in the idle state, the UE receives the DTX mode information broadcast by the serving base station of the UE through a broadcast message; or, when the UE is in the connected state, The UE receives the DTX mode information broadcast by the serving base station of the UE through a broadcast message, or receives the DTX mode information sent by the serving base station of the UE through a radio resource control (Radio Resource Control; RRC for short) message.

Wherein, the DTX mode information sent by the serving base station of the above-mentioned UE may be sent by the serving base station of the adjacent NCT cell to the serving base station of the above-mentioned UE through the X2 interface; or, the DTX mode information sent by the serving base station of the above-mentioned UE may be The serving base station of the cell sends a message through the S1 interface to the first mobile management entity (Mobile Management Entity; MME) to which the serving base station of the adjacent NCT cell belongs, and then the first MME sends it to the first mobile management entity to which the serving base station of the above UE belongs. Two MMEs, and then the second MME sends a message to the serving base station of the above-mentioned UE through the S1 interface. Optionally, the above-mentioned first MME and the second MME may be the same MME, or different MMEs; or, the above-mentioned UE The DTX mode information sent by the serving base station of the UE may be obtained by the serving base station of the UE through operation, maintenance and management (Operation Administration and Maintenance, OAM for short).

Of course, the above are just several examples of how the serving base station of the UE obtains the DTX mode information.

Step 102, the UE measures the neighboring NCT cells according to the above DTX mode information.

Specifically, the UE can obtain the sending time of the downlink pilot of the adjacent NCT cell according to the above DTX mode information, and measure the adjacent NCT cell at the above downlink pilot sending time; or, the UE can obtain the corresponding NCT cell according to the above DTX mode information. The time-frequency position of the downlink pilot of the adjacent NCT cell, and measure the adjacent NCT cell at the time-frequency position of the above-mentioned downlink pilot; or, the UE can obtain the transmission time of the downlink pilot of the adjacent NCT cell according to the above-mentioned DTX mode information and time-frequency position, the adjacent NCT cells are measured at the sending time and time-frequency position of the downlink pilot.

For example, when the serving base station only transmits the transmission time information of the downlink pilot, that is, the DTX mode information includes the transmission time information of the downlink pilot, but does not include the time-frequency position information of the downlink pilot, the UE will go to the specified time at the indicated time. The specific time-frequency position can be fixed by the protocol or obtained according to certain rules. When the serving base station only transmits the time-frequency position information of the downlink pilot, that is, the DTX mode information includes the time-frequency position information of the downlink pilot, but does not include the transmission time information of the downlink pilot, the UE goes to the indicated time-frequency at a specific time The location to receive the pilot, the specific time can be fixed by the protocol or obtained according to certain rules. When the serving base station transmits the transmission time information of the downlink pilot and the time-frequency position information of the downlink pilot at the same time, that is, the DTX mode information includes the transmission time information of the downlink pilot and the time-frequency position information of the downlink pilot at the same time, the UE is in the indicated Time to go to the indicated location to receive the pilot.

In the above embodiment, the UE receives the DTX mode information of the adjacent NCT cell sent by the serving base station of the UE, so that the UE can learn the relevant information of the downlink pilot of the adjacent NCT cell, and then the UE performs the DTX mode information on the adjacent NCT cell according to the DTX mode information. The NCT cell performs measurement, thereby avoiding power waste caused by unnecessary measurement and saving UE power.

Please continue to refer to FIG. 2. FIG. 2 is a flow chart of another embodiment of the method for measuring a new carrier type cell in the present invention. As shown in FIG. 2, optionally, the above method for measuring an NCT cell may also include:

In step 201, the UE receives the measurement parameters of the above-mentioned neighboring NCT cell sent by the serving base station of the UE.

In step 202, the UE sends indication information to the adjacent NCT cell according to the measurement result of the adjacent NCT cell and the received measurement parameters, and the indication information is used to instruct the adjacent NCT cell to perform an activation operation.

In this way, when the NCT cell is in the sleep state, the UE enters the NCT cell, and can instruct the NCT cell to perform an activation operation through the indication information, thereby solving the problem that the NCT cell in the sleep state cannot serve the UE entering the NCT cell.

It should be noted that there is no sequence restriction between the above step 201 and steps 101 and 102, that is, the DTX mode information may be received first, the measurement parameters may be received first, or the DTX mode information and measurement parameters may be received at the same time. In addition, the measurement parameters may also be received after step 102, that is, after the measurement of the adjacent NCT cell is completed. The embodiment of the present invention does not make any limitation.

Wherein, the above-mentioned measurement parameters include one or more of the following information: the above-mentioned indication information, the resource information of the above-mentioned indication information, the transmission mode of the above-mentioned indication information, and the sending conditions of the above-mentioned indication information. The indication information is used to notify the UE of the type of indication information to be sent; the resource information of the above indication information is used to inform the UE of the resources used to send the above indication information; the sending method of the above indication information is used to inform the UE of what method to send The above indication information, for example: periodic transmission, event trigger or one-time transmission, etc., is not limited in this embodiment of the present invention; the transmission condition of the above indication information is used to inform the UE under what conditions to send the indication information, for example: UE is in the opposite When the measurement result of the neighboring NCT cell satisfies the sending condition, the UE will send indication information to the neighboring NCT cell.

For example, the measurement parameter may include indication information and a sending condition of the indication information. At this time, the above step 202 includes: when the measurement result of the UE on the adjacent NCT cell satisfies the sending condition of the above indication information, the UE sends the indication information to the adjacent NCT cell, so that the adjacent NCT cell Perform the cell activation operation. Further, if the measurement parameter includes the sending manner of the indication information, the UE sends the indication information to the neighboring NCT cell according to the sending manner of the indication information. Of course, the measurement parameters may only include indication information, and the sending conditions and methods of the indication information are preset on the UE side, or may be fixed by the protocol or acquired according to certain rules; or the measurement parameters include indication information, indication information sending It is one of the ways to send the condition and instruction information. Other information not included is preset on the UE side, or can be fixed by the protocol or obtained according to certain rules.

For another example, the measurement parameter may include one of the indication information and the resource information of the indication information, or include both the indication information and the resource information of the indication information. That is to say, the serving base station may only notify the UE what the indication information to be sent is, so that the UE may use the resource corresponding to the indication information to send the indication information; the serving base station may also only notify the UE what the resource used to send the indication information is, so that the UE According to the resource information, it can determine what the indication information to be sent is, and then use the resource to send the indication information; of course, the serving base station can also notify the UE of the indication information to be sent and the resources used for sending at the same time, so that the UE can be notified. Send instructions on the resource.

For example, when the indication information to be sent is a random access code, the serving base station may notify the UE that the indication information to be sent is a random access code (that is, the measurement parameter includes the indication information), or notify the UE of the resources used to send the indication information It is a random access resource (that is, the measurement parameter includes the resource information of the indication information); or at the same time, the UE is notified that the indication information to be sent is a random access code and the resource used to send the indication information is a random access resource (that is, the measurement parameter includes the indication information at the same time) information and resource information of the indication information), at this time, sending the indication information to the adjacent NCT cell may be: the UE sends the above random access code to the adjacent NCT cell through the above random access resource.

When the above indication information to be sent is a scheduling request (Scheduling Request; hereinafter referred to as: SR), the measurement parameters may include SR information and/or SR resources; at this time, sending the indication information to a neighboring NCT cell may be: UE through SR resources send SR to neighboring NCT cells.

When the above indication information to be sent is Sounding Reference Signaling (Sounding Reference Signaling; hereinafter referred to as: SRS), the measurement parameters may include SRS information and/or SRS resources, and at this time, sending the indication information to a neighboring NCT cell may be : The UE sends the SRS to the neighboring NCT cell through the SRS resource.

When the indication information to be sent is other forms of uplink information, the UE sends the indication information (uplink indication signaling) to the neighboring NCT cell through the uplink resources corresponding to the other forms of uplink information.

In short, the measurement parameters may include one or more of the above information. If there is information that needs to be used but not included in the measurement parameters, it may be preset at the UE side, or may be fixed by the protocol or acquired according to certain rules. In addition, the measurement parameters may also include all the above information at the same time. The embodiment of the present invention does not make any limitation.

In addition, the above DTX mode information may also include status information of the NCT cell, which is used to indicate whether the NCT cell is in a sleep state. In this way, when the UE knows that the NCT cell is in the sleep state, it sends the indication information according to the measurement parameters, which can save resources. Certainly, the UE may also judge whether to send the indication information based on the sending condition of the indication information without knowing the state information of the NCT cell.

Further, in this embodiment, when the NCT cell is in the active state, the UE may also receive the RRC reconfiguration command sent by the serving base station in the NCT cell; thus, according to the RRC reconfiguration command, the report power preference indicator (PowerPreference Indicator; Hereinafter referred to as: PPI) function, which reports PPI to the serving base station of the NCT cell in the active state, and the value of the PPI is used to indicate "normal" or "power saving"; so that the serving base station of the NCT cell in the active state When the reported PPI value indicates power saving, configure the above-mentioned UE to the power saving state. For example, after the UE reports the power saving indication, the serving base station of the NCT cell can configure a longer Discontinuous Receive (Discontinuous Receive; the following Abbreviation: DRX) cycle or release RRC connection, etc.

In addition, when the number of UEs reporting the power-saving indication reaches a certain proportion, the serving base station of the NCT cell may also handover the UEs to an adjacent cell, so that the NCT cell enters a sleep state. For example, when the serving base station of the NCT cell determines that the number of PPIs whose value represents "power saving" is greater than the number of PPIs whose value represents "normal" within a predetermined period of time, and the number of PPIs whose value represents "power saving" is the same as the number of PPIs whose value represents "normal" When the difference in the number of PPIs of " is greater than or equal to the preset threshold, the serving base station of the NCT cell enters a sleep state, and switches the UE served by the above NCT cell back to the macro cell.

Or, when the ratio of the number of UEs reporting power saving indications to the total number of UEs in the connected state is greater than or equal to a preset ratio value, the serving base station of the NCT cell enters a sleep state, and switches the UEs served by the NCT cell back to the macro cell.

In the above embodiment, the UE receives the DTX mode information of the adjacent NCT cell sent by the serving base station of the UE, so that the UE can learn the relevant information of the downlink pilot of the adjacent NCT cell, and then the UE performs the DTX mode information on the adjacent NCT cell according to the DTX mode information. The NCT cell performs measurement, thereby avoiding power waste caused by unnecessary measurement and saving UE power.

In addition, the above DTX mode information may also include status information of the NCT cell, which is used to indicate whether the NCT cell is in a sleep state. In this way, when the UE knows that the NCT cell is in the sleep state, it sends the indication information according to the measurement parameters, which can save resources. Certainly, the UE may also judge whether to send the indication information based on the sending condition of the indication information without knowing the state information of the NCT cell.

Step 302, the base station sends the aforementioned DTX mode information to the aforementioned UE, so that the UE can measure neighboring NCT cells according to the aforementioned DTX mode information.

Specifically, the base station sending the DTX mode information to the UE served by the base station may be: the base station broadcasts the DTX mode information to the UE served by the base station through a broadcast message; or, the base station sends the DTX mode information to the UE in the connected state served by the base station through an RRC message. schema information.

Wherein, the DTX mode information sent by the above-mentioned base station is sent to the base station by the serving base station of the adjacent NCT cell through the X2 interface; or, the DTX mode information sent by the above-mentioned base station is sent to the base station by the serving base station of the adjacent NCT cell through the S1 interface message The first MME to which the serving base station of the adjacent NCT cell belongs is sent by the first MME to the second MME to which the base station belongs, and then the second MME sends a message to the above-mentioned base station through the S1 interface message. Optionally, the above-mentioned first The MME and the second MME may be the same MME or different MMEs; or, the DTX mode information sent by the base station is obtained by the base station through OAM.

Of course, the above are only several examples for the base station to obtain the DTX mode information, and the embodiment of the present invention is not limited thereto, and the embodiment of the present invention does not limit the manner in which the base station obtains the DTX mode information.

Further, the base station also sends measurement parameters of neighboring NCT cells to the UE, where the measurement parameters include one or more of the following information: indication information, resource information of the indication information, sending conditions of the indication information, and sending method.

The indication information is used to notify the UE of the type of indication information to be sent; the resource information of the above indication information is used to inform the UE of the resources used to send the above indication information; the sending method of the above indication information is used to inform the UE of what method to send The above indication information, for example: periodic transmission, event trigger or one-time transmission, etc., is not limited in this embodiment of the present invention; the transmission condition of the above indication information is used to inform the UE under what conditions to send the indication information, for example: UE is in the opposite When the measurement result of the neighboring NCT cell satisfies the sending condition, the UE will send indication information to the neighboring NCT cell.

In this embodiment, the measurement parameters may include one or more of the above information. If there is information that needs to be used but not included in the measurement parameters, it may be preset at the UE side, or may be fixed by the protocol or obtained according to certain rules. In addition, the measurement parameters may also include all the above information at the same time. The embodiment of the present invention does not make any limitation.

In the above embodiment, the base station sends the DTX mode information of the adjacent cell to the UE served by the base station, so that the UE can know the relevant information of the downlink pilot of the adjacent NCT cell, and then the UE sends the adjacent NCT cell information according to the DTX mode information. Measurement is performed to avoid power waste caused by unnecessary measurement and save UE power; in addition, UE can send signaling to enable the NCT cell to switch between active and sleep states.

Fig. 4 is the flow chart of another embodiment of the measurement method of the new carrier type cell of the present invention, as shown in Fig. 4, the measurement method of the NCT cell may include:

In step 401, the serving base station of the NCT cell obtains the DTX mode information of the NCT cell.

Wherein, the above DTX mode information includes one or a combination of the following information: sending time information of the downlink pilot and time-frequency position information of the downlink pilot.

In addition, the above DTX mode information may also include status information of the NCT cell, which is used to indicate whether the NCT cell is in a sleep state. In this way, when the UE knows that the NCT cell is in the sleep state, it sends the indication information according to the measurement parameters, which can save resources. Certainly, the UE may also judge whether to send the indication information based on the sending condition of the indication information without knowing the state information of the NCT cell.

Step 402, the serving base station of the NCT cell sends the DTX mode information to the serving base station of the neighboring cell, so that the serving base station of the neighboring cell sends the above-mentioned DTX mode information to the UE served by the serving base station of the neighboring cell, and the UE is based on the above-mentioned DTX mode information. The above-mentioned NCT cell is measured.

The above DTX mode information can be obtained by the serving base station of the NCT cell through OAM; it can also be configured by the serving base station of the NCT cell according to the current service or topology information, which is not limited in this embodiment of the present invention.

Specifically, the serving base station of the NCT cell sends the DTX mode information of the NCT cell to the serving base station of the adjacent cell may be: the serving base station of the NCT cell sends the above-mentioned DTX mode information of the NCT cell to the serving base station of the adjacent cell through the X2 interface; or, The serving base station of the NCT cell sends the DTX mode information of the NCT cell to the first MME to which the serving base station of the NCT cell belongs through the S1 interface message, and then the first MME sends the DTX mode information of the NCT cell to the serving cell of the adjacent cell The second MME to which the base station belongs, and then the second MME sends the DTX mode information of the above-mentioned NCT cell to the serving base station of the neighboring cell through the S1 interface message. Optionally, the above-mentioned first MME and the second MME may be the same MME, It can also be a different MME.

Further, after the serving base station of the NCT cell sends the DTX mode information to the serving base station of the adjacent cell, the serving base station of the above-mentioned NCT cell may also receive the instruction information sent by the UE, and perform the cell activation operation according to the instruction information.

Further, when the NCT cell is in an activated state, the serving base station of the NCT cell sends an RRC reconfiguration command to the UE, so that the UE enables the function of reporting PPI; then, the serving base station of the NCT cell receives the PPI reported by the user equipment, The value of the above PPI is used to indicate "normal" or "power saving"; next, the serving base station of the NCT cell configures the state of the UE and/or the NCT cell according to the above PPI.

Specifically, the serving base station of the NCT cell configures the UE in the power saving state when the PPI value reported by the UE indicates power saving. For example, after the UE reports the power saving indication, the serving base station of the NCT cell can configure Longer DRX cycle or releasing RRC connection etc.

In addition, when the number of UEs reporting the power-saving indication reaches a certain proportion, the serving base station of the NCT cell may also handover the UEs to an adjacent cell, so that the NCT cell enters a sleep state. For example, when the serving base station of the NCT cell determines that the number of PPIs whose value represents "power saving" is greater than the number of PPIs whose value represents "normal" within a predetermined period of time, and the number of PPIs whose value represents "power saving" is the same as the number of PPIs whose value represents "normal" When the difference in the number of PPIs of " is greater than or equal to the preset threshold, the serving base station of the NCT cell enters a sleep state, and switches the UE served by the above NCT cell back to the macro cell.

Or, when the ratio of the number of UEs reporting power saving indications to the total number of UEs in the connected state is greater than or equal to a preset ratio value, the serving base station of the NCT cell enters a sleep state, and switches the UEs served by the NCT cell back to the macro cell.

In the above embodiment, the serving base station of the NCT cell sends the DTX mode information of the NCT cell to the serving base station of the adjacent cell, so that the serving base station of the adjacent cell sends the above-mentioned DTX mode information to the UE served by the serving base station of the adjacent cell, thereby The UE can learn the relevant information of the downlink pilot of the adjacent NCT cell, and then the UE measures the adjacent NCT cell according to the DTX mode information, so as to avoid the waste of power caused by unnecessary measurement and save the power of the UE; in addition, The UE can send signaling to enable the NCT cell to switch between active and sleep states.

Fig. 5 is the flow chart of another embodiment of the measurement method of the new carrier type cell of the present invention, as shown in Fig. 5, the measurement method of the NCT cell may include:

Step 501, the serving base station of the UE sends the DTX mode information of the adjacent NCT cell of the serving cell where the UE is located to the UE.

Wherein, the DTX mode information may be related information of a downlink pilot, and the downlink pilot may include a primary synchronization signal (Primary Synchronization Signal; hereinafter referred to as: PSS), a secondary synchronization signal (Secondary Synchronization Signal; hereinafter referred to as: SSS), and a cell reference signal (Cell-specific Reference Signal; hereinafter referred to as: CRS), channel state information reference signal (Channel-State Information Reference Signals; hereinafter referred to as: CSI-RS) or other newly designed pilot. The above DTX mode information includes one or a combination of the following information: downlink pilot transmission time information and downlink pilot time-frequency position information; in addition, the above DTX mode information may also include whether the NCT cell is in a sleep state or not.

Specifically, the base station may broadcast DTX mode information to UEs served by the base station through a broadcast message; for UEs in a connected state, the base station may send DTX mode information to UEs in a connected state served by the base station through an RRC message.

Step 502, the UE measures the neighboring NCT cells according to the above DTX mode information.

Specifically, the UE can obtain the sending time of the downlink pilot of the adjacent NCT cell according to the above DTX mode information, and measure the adjacent NCT cell at the above downlink pilot sending time; or, the UE can obtain the corresponding NCT cell according to the above DTX mode information. The time-frequency position of the downlink pilot of the adjacent NCT cell, and measure the adjacent NCT cell at the time-frequency position of the above-mentioned downlink pilot; or, the UE can obtain the transmission time of the downlink pilot of the adjacent NCT cell according to the above-mentioned DTX mode information and time-frequency position, the adjacent NCT cells are measured at the sending time and time-frequency position of the downlink pilot.

For example, when the serving base station only transmits the transmission time information of the downlink pilot, that is, the DTX mode information includes the transmission time information of the downlink pilot, but does not include the time-frequency position information of the downlink pilot, the UE will go to the specified time at the indicated time. The specific time-frequency position can be fixed by the protocol or obtained according to certain rules. When the serving base station only transmits the time-frequency position information of the downlink pilot, that is, the DTX mode information includes the time-frequency position information of the downlink pilot, but does not include the transmission time information of the downlink pilot, the UE goes to the indicated time-frequency at a specific time The location to receive the pilot, the specific time can be fixed by the protocol or obtained according to certain rules. When the serving base station transmits the transmission time information of the downlink pilot and the time-frequency position information of the downlink pilot at the same time, that is, the DTX mode information includes the transmission time information of the downlink pilot and the time-frequency position information of the downlink pilot at the same time, the UE is in the indicated Time to go to the indicated location to receive the pilot.

Further, after the adjacent NCT cell is measured, for the idle state UE, if the measurement result of the adjacent NCT cell satisfies the cell reselection condition, the UE reselects to the above-mentioned adjacent NCT cell.

For a UE in a connected state, if the measurement result of a neighboring NCT cell meets the measurement reporting conditions, the UE reports the measurement result to assist the serving base station of the UE in making a handover decision.

Wherein, the serving cell of the UE may be a macro cell, a micro cell or a pico cell, may also be an NCT cell, or may be a traditional cell, which is not limited here.

In an implementation of this embodiment, the DTX mode information sent by the serving base station of the UE may be sent by the serving base station of the NCT cell through the X2 interface (that is, the interface between the serving base station of the NCT cell and the serving base station of the UE) For the serving base station of the aforementioned UE. Specifically, the transmission of the DTX mode information can be realized by designing a new X2 interface message, or adding a new information element to the original X2 interface message. A specific implementation may be that the serving base station of the above-mentioned NCT cell transmits the DTX mode information of the above-mentioned NCT cell through an X2 interface message (for example: a base station configuration update message, the base station configuration update message includes the DTX mode information of the above-mentioned NCT cell) Inform the serving base station of the UE that after receiving the DTX mode information of the NCT cell sent by the serving base station of the NCT cell, the serving base station of the UE sends a message to the serving base station of the NCT cell through an X2 interface message (for example: a base station configuration update confirmation message) confirm.

In another implementation of this embodiment, the DTX mode information sent by the serving base station of the UE may be that the serving base station of the NCT cell notifies the first MME to which the serving base station of the NCT cell belongs through an S1 interface message, and then the first MME to which the serving base station of the NCT cell belongs An MME sends the message to the second MME to which the serving base station of the UE belongs, and then the second MME sends the message to the serving base station of the UE through the S1 interface message. The serving base station of the aforementioned UE may send a confirmation message to the second MME through the S1 interface between it and the second MME, and then the second MME may send a confirmation message to the first MME, and the first MME may communicate with the serving base station of the NCT cell. The S1 interface between them sends an acknowledgment message to the serving base station of the NCT cell. In particular, when the serving base station of the NCT cell is the same as the MME to which the serving base station of the UE belongs, that is, when the first MME and the second MME are the same MME, the above-mentioned messages between MMEs can be omitted.

In another implementation manner of this embodiment, the DTX mode information sent by the serving base station of the UE may be obtained by the serving base station of the UE through OAM.

The above embodiments can enable the UE to know the relevant information of the downlink pilots of adjacent NCT cells, avoid power waste caused by performing measurements at non-downlink pilot transmission time, and save the power of the UE.

FIG. 6 is a flow chart of another embodiment of the method for measuring a new carrier type cell according to the present invention. As shown in FIG. 6, the method for measuring an NCT cell may include:

In step 601, the UE receives the measurement parameters of the neighboring NCT cells sent by the serving base station of the UE.

It should be noted that there is no order restriction between the above step 601 and steps 501 and 502, that is, the DTX mode information may be received first, the measurement parameters may be received first, or the DTX mode information and measurement parameters may be received at the same time. In addition, the measurement parameter may be received after step 502, that is, after the measurement of the adjacent NCT cell is completed. The embodiment of the present invention does not make any limitation.

Wherein, the above-mentioned measurement parameters include one or more of the following information: the above-mentioned indication information, the resource information of the above-mentioned indication information, the transmission mode of the above-mentioned indication information, and the sending conditions of the above-mentioned indication information. The indication information is used to notify the UE of the type of indication information to be sent; the resource information of the above indication information is used to inform the UE of the resources used to send the above indication information; the sending method of the above indication information is used to inform the UE of what method to send The above indication information, for example: periodic transmission, event trigger or one-time transmission, etc., is not limited in this embodiment of the present invention; the transmission condition of the above indication information is used to inform the UE under what conditions to send the indication information, for example: UE is in the opposite When the measurement result of the neighboring NCT cell satisfies the sending condition, the UE will send indication information to the neighboring NCT cell.

Specifically, the serving base station of the UE may send the above measurement parameters to the UE through a system broadcast message; for the UE in the connected state, the serving base station of the UE may also send the above measurement parameters to the UE in the connected state through an RRC message, Optionally, after the UE in the connected state receives the above measurement parameters through an RRC message, the UE in the connected state sends a completion message to the serving base station of the UE.

Specifically, the message used by the serving base station of the UE to send the measurement parameter may be a newly designed message, or may be a new information element (Information Element; hereinafter referred to as: IE) added to an existing message. Optionally, some or all of the measurement parameters may also be notified to the UE in other ways, such as a fixed protocol, and the present invention does not limit the way of sending the measurement parameters.

Step 602, the UE measures the neighboring NCT cells.

Wherein, the UE can measure the adjacent NCT cell according to the preset measurement strategy, and the above measurement parameters can also carry the parameter information that needs to be measured by the UE, so that the UE can measure according to the parameter information that needs to be measured.

Step 603, if it is determined that the measurement result of the UE on the neighboring NCT cell satisfies the sending condition of the indication information, then the UE sends the indication information to the neighboring NCT cell.

For example, the measurement parameter may include indication information and a sending condition of the indication information. At this time, the above step 603 includes: when the measurement result of the UE on the adjacent NCT cell satisfies the sending condition of the above indication information, the UE sends the indication information to the adjacent NCT cell, so that the adjacent NCT cell Perform the cell activation operation. Further, if the measurement parameter includes the sending manner of the indication information, the UE sends the indication information to the neighboring NCT cell according to the sending manner of the indication information. Of course, the measurement parameters may only include indication information, and the sending conditions and methods of the indication information are preset on the UE side, or may be fixed by the protocol or acquired according to certain rules; or the measurement parameters include indication information, indication information sending It is one of the ways to send the condition and instruction information. Other information not included is preset on the UE side, or can be fixed by the protocol or obtained according to certain rules.

For another example, the measurement parameter may include one of the indication information and the resource information of the indication information, or include both the indication information and the resource information of the indication information. That is to say, the serving base station may only notify the UE what the indication information to be sent is, so that the UE may use the resource corresponding to the indication information to send the indication information; the serving base station may also only notify the UE what the resource used to send the indication information is, so that the UE According to the resource information, it can determine what the indication information to be sent is, and then use the resource to send the indication information; of course, the serving base station can also notify the UE of the indication information to be sent and the resources used for sending at the same time, so that the UE can be notified. Send instructions on the resource.

For example, when the indication information to be sent is a random access code, the serving base station may notify the UE that the indication information to be sent is a random access code (that is, the measurement parameter includes the indication information), or notify the UE of the resources used to send the indication information It is a random access resource (that is, the measurement parameter includes the resource information of the indication information); or at the same time, the UE is notified that the indication information to be sent is a random access code and the resource used to send the indication information is a random access resource (that is, the measurement parameter includes the indication information at the same time) information and resource information indicating information); at this time, the UE may send the random access code to the neighboring NCT cell through the random access resource.

When the indication information to be sent is SR, the measurement parameters may include SR information and/or SR resources; at this time, the UE may send the SR to the neighboring NCT cell through the SR resources.

When the indication information to be sent is SRS, the measurement parameter may include SRS information and/or SRS resource, and at this time, the UE may send the SRS to the neighboring NCT cell through the SRS resource.

When the indication information to be sent is other forms of uplink information, the UE sends the indication information (uplink indication signaling) to the neighboring NCT cell through the uplink resources corresponding to the other forms of uplink information.

In short, the measurement parameters may include one or more of the above information. If there is information that needs to be used but not included in the measurement parameters, it may be preset at the UE side, or may be fixed by the protocol or acquired according to certain rules. In addition, the measurement parameters may also include all the above information at the same time. The embodiment of the present invention does not make any limitation.

In this embodiment, the sending condition of the above-mentioned indication information may be that the signal instruction of the neighboring cell reaches the threshold value. Of course, this is only an example of the sending condition of the above-mentioned indication information, and the present invention is not limited thereto. The conditions for sending the information are not limited.

Optionally, the resource information of the above indication information may be sent by the serving base station of the NCT cell to the serving base station of the UE through an X2 interface message with the serving base station of the UE, or may be sent by the serving base station of the NCT cell through the MME The information forwarded by the S1 interface to the UE's serving base station can also be obtained through OAM. The specific method is similar to the method of sending DTX mode information in the embodiment shown in FIG. 5 of the present invention, and will not be repeated here.

Optionally, one or more of the above measurement parameters may be sent by the serving base station of the NCT cell to the serving base station of the UE through an X2 interface message with the serving base station of the UE, or may be the serving base station of the NCT cell What the base station forwards to the serving base station of the UE through the S1 interface through the MME can also be obtained through OAM. The specific method is similar to the method of sending DTX mode information in the embodiment shown in FIG. 5 of the present invention, and will not be described here.

Step 604, after the adjacent NCT cell receives the above indication information sent by the UE, the adjacent NCT cell may perform a cell activation operation according to the above indication information.

In this way, when the NCT cell is in the sleep state, the UE enters the NCT cell, and can instruct the NCT cell to perform an activation operation through the indication information, thereby solving the problem that the NCT cell in the sleep state cannot serve the UE entering the NCT cell.

Specifically, if the above-mentioned NCT cell has received one or more such indication information, then information such as the average signal strength of these indication information or the occurrence density of indication information (such as the number of indication signaling received within a period of time) can be used to After comprehensive consideration, it is decided to perform an activation operation to provide services for the above-mentioned UE. Whether the NCT cell is finally activated depends on different implementations, and the present invention does not make too many limitations.

Since the present invention considers whether to activate the NCT cell through the indication signaling information of one or more UEs received by the NCT cell, the indication signaling information sent by the above multiple UEs to the same NCT cell can be configured to be the same. Certainly, different measurement parameters may also be configured for different UEs.

Correspondingly optionally, if the above NCT cell is in the activated state, but the average signal strength or occurrence density of the indication signaling sent by the UE is poor, the NCT cell can re-enter the sleep state to end the service for the UE.

In addition, when the NCT cell is in the active state, the UE can also receive the RRC reconfiguration command sent by the serving base station of the NCT cell; thus, according to the RRC reconfiguration command, the function of reporting PPI is enabled, and the serving base station of the NCT cell in the active state Report the PPI, the value of which is used to indicate "normal" or "power-saving"; so that the serving base station of the NCT cell configures the above-mentioned UE to a power-saving state when the value of the PPI reported by the above-mentioned UE indicates power-saving, for example, After the UE reports the power saving indication, the serving base station of the NCT cell can configure a longer DRX cycle or release the RRC connection for it.

In addition, when the number of UEs reporting the power-saving indication reaches a certain proportion, the serving base station of the NCT cell may also handover the UEs to an adjacent cell, so that the NCT cell enters a sleep state. For example, when the serving base station of the NCT cell determines that the number of PPIs whose value represents "power saving" is greater than the number of PPIs whose value represents "normal" within a predetermined period of time, and the number of PPIs whose value represents "power saving" is the same as the number of PPIs whose value represents "normal" When the difference in the number of PPIs of " is greater than or equal to the preset threshold, the serving base station of the NCT cell enters a sleep state, and switches the UE served by the above NCT cell back to the macro cell.

Or, when the ratio of the number of UEs reporting power saving indications to the total number of UEs in the connected state is greater than or equal to a preset ratio value, the serving base station of the NCT cell enters a sleep state, and switches the UEs served by the NCT cell back to the macro cell.

If the UE in the RRC connection state of the macro cell in this NCT cell meets the conditions in the embodiment shown in Figure 6 of the present invention again, the NCT cell will be awakened again according to the scheme of the embodiment shown in Figure 6 of the present invention, thus forming A complete NCT cell activation state and sleep state conversion scheme.

The NCT cell measurement method provided by the present invention can reduce the unnecessary measurement process of the UE entering the NCT cell, and at the same time, the UE can send signaling to enable the NCT cell to switch between wake-up and sleep states.

In addition, the above DTX mode information may also include status information of the NCT cell, which is used to indicate whether the NCT cell is in a sleep state. In this way, when the UE knows that the NCT cell is in the sleep state, it sends the indication information according to the measurement parameters, which can save resources. Certainly, the UE may also judge whether to send the indication information based on the sending condition of the indication information without knowing the state information of the NCT cell.

Neighboring NCT cells perform measurements, thereby avoiding power waste due to unnecessary measurements and saving user equipment power; in addition, the UE can send signaling to enable NCT cells to switch between active and sleep states.

The UE in this embodiment can implement the process of the embodiment shown in FIG. 2 of the present invention. Compared with the UE shown in FIG. 7 , the difference lies in that In the UE shown in 8,

Send instructions on the resource.

For example, when the indication information to be sent is a random access code, the serving base station may notify the UE that the indication information to be sent is a random access code (that is, the measurement parameter includes the indication information), or notify the UE of the resources used to send the indication information It is a random access resource (that is, the measurement parameter includes the resource information of the indication information); or at the same time, the UE is notified that the indication information to be sent is a random access code and the resource used to send the indication information is a random access resource (that is, the measurement parameter includes the indication information at the same time) information and resource information indicating information), at this time, the sending module 73 is specifically configured to send the random access code to the adjacent NCT cell through random access resources;

Or, when the above indication information is SR, the measurement parameters may include SR information and/or SR resources; at this time, the sending module 73 is specifically configured to send the above SR to the neighboring NCT cell through the SR resource;

In addition, the measurement parameters may also include all the above information at the same time. The embodiment of the present invention does not make any limitation.

In addition, when the number of UEs reporting the power-saving indication reaches a certain proportion, the serving base station of the NCT cell may also handover the UEs to an adjacent cell, so that the NCT cell enters a sleep state. For example, when the serving base station of the NCT cell determines that the number of PPIs whose value represents "power saving" is greater than the number of PPIs whose value represents "normal" within a predetermined period of time, and the number of PPIs whose value represents "power saving" is the same as the number of PPIs whose value represents "normal" When the difference in the number of PPIs of " is greater than or equal to the preset threshold, the serving base station of the NCT cell enters a sleep state, and switches the UE served by the above NCT cell back to the macro cell.

Or, when the ratio of the number of UEs reporting power saving indications to the total number of UEs in the connected state is greater than or equal to a preset ratio value, the serving base station of the NCT cell enters a sleep state, and switches the UEs served by the NCT cell back to the macro cell.
