Description

Measuring method, device and system

Technical Field

The present application relates to the field of communications, and in particular, to a measurement method, device, and system.

Background

As the number of User Equipments (UEs) in a wireless network and the amount of communication required by each UE increase, the load of the network side Equipment will increase. Therefore, Device-to-Device (D2D) communication is introduced in a Long Term Evolution (LTE) wireless network, that is, data is directly transmitted between two UEs without transferring the data to a network side Device, which not only reduces the load of the network side Device, but also reduces the transmission delay.

Currently, the resources used for D2D communication are divided from the resources for communication between the entire base station and the UE, and adopt a half-duplex mode and configure a single carrier. According to the technical scheme, the quality of a link (called as a D2D link) between D2D devices is known through D2D measurement signals between the D2D devices, and the quality is used for determining the size of data transmitted by the D2D link. At the same time, a UE engaged in D2D communication may communicate with the base station and also send a Device-to-network Device (D2G) measurement signal to measure the quality of the link between the UE and the base station (referred to as the D2G link).

In the current scheme, measurement configuration information is generally sent by the base station to the UE, instructing the UE to send or receive D2G measurement signals and D2D measurement signals. The measurement configuration information may include, but is not limited to, resource information, sequence information for generating a measurement signal, and the like. However, the measurement configuration information may indicate that the UE transmits both the D2D and D2G measurement signals at the same time, and a collision of the D2D measurement signal and the D2G measurement signal occurs.

However, since the UE cannot transmit a plurality of signals at the same time due to the limitation of the single carrier mode of the D2D communication configuration, the collision problem between the D2D measurement signal and the D2G SRS measurement signal is solved, which is a problem to be solved in the D2D communication.

Disclosure of Invention

The embodiment of the application provides a measuring method, a device and a system, and solves the problem of collision of measuring signals in device communication.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, a measurement method is provided and applied to a measurement-side device. The method comprises the steps that measurement configuration information sent by network side equipment is received by measurement end equipment, and the measurement configuration information is used for indicating sending end equipment to send a measurement signal; if the sending end equipment needs to send the first measurement signal and the second measurement signal at the moment t, the measurement end equipment measures the first measurement signal or the second measurement signal at the moment t to obtain a measurement result of the measurement signal; or, if the sending end device needs to send the first measurement signal and the second measurement signal at time t, the measuring end device stops measuring the measurement signal at time t. The first measurement signal is a measurement signal from the sending end device to the measurement end device, and the second measurement signal is a measurement signal from the sending end device to the network side device.

According to the measurement method, when a measurement signal from a sending end device to a measurement end device collides with a measurement signal from the sending end device to a network side device in device communication, the measurement end device only measures the measurement signal from the sending end device to the measurement end device or the measurement signal from the sending end device to the network side device at the time of collision, or the measurement end device stops measuring the measurement signal at the time of collision, and under the condition that a communication framework is not changed, the problem of collision of the measurement signal in the device communication is solved.

In one aspect, an embodiment of the present application provides a communication device. Fig. 2 illustrates a communication device 20 in connection with various embodiments of the present application.

On the other hand, the embodiment of the application provides a network side device. Fig. 3 illustrates a network-side device 30 according to various embodiments of the present application. The network side device 30 may be the network side device 102 in the communication system architecture shown in fig. 1. As shown in fig. 3, the network-side device 30 may include: a processor 301, a memory 302, a transceiver 303.

The following describes each component of the network-side device 30 in detail with reference to fig. 3:

The processor 301 is a control center of the network-side device 30, and may be a CPU, an ASIC, or one or more integrated circuits configured to implement the embodiments of the present application, for example: one or more DSPs, or one or more FPGAs. The processor 301 may perform various functions of the network-side device 30 by running or executing software programs and/or modules stored in the memory 302, as well as invoking data stored in the memory 302.

The transceiver 303 is used for the network side device 30 to interact with other units. Illustratively, the transceiver 303 may be a transceiving antenna of the network-side device 30.

Specifically, the processor 301 executes or executes the software programs and/or modules stored in the memory 302, and calls the data stored in the memory 302, to perform the following functions:

Optionally, the processor 301 executes or executes the software programs and/or modules stored in the memory 302, and calls the data stored in the memory 302 to perform the following functions:

In another aspect, an embodiment of the present application provides a measurement method. The following describes a measurement method provided in the embodiment of the present application, by taking an interaction process among a network side device, a sending end device, and a measurement end device as an example. As shown in fig. 4, the method may include:

s401, the network side equipment sends measurement configuration information to the sending end equipment and the measuring end equipment.

The measurement configuration information is used for instructing the sending end device to send a measurement signal. The measurement signal is used by the measurement-side device to estimate the channel quality of the path through which the measurement signal travels. The embodiment of the present application does not specifically limit the form and content of the measurement configuration information, and all information used for instructing the sending end device to send the measurement signal may be referred to as the measurement configuration information described in the present application.

Illustratively, the measurement configuration information may include at least one of the following information: the method includes the steps of transmitting resource (time domain resource, frequency domain resource, code domain resource and the like) information of a measurement signal, and generating sequence information of the measurement signal, transmission power or power spectrum of the measurement signal, a first reference signal received power spectrum expected by a measurement end, a second reference signal received power spectrum expected by a network side device and the like.

Optionally, the measurement configuration information may be used to instruct the sending end device to send at least one of a measurement signal from the sending end device to the measurement end device and a measurement signal from the sending end device to the network side device.

When the communication device is a UE, the measurement signal from the sending end device to the measurement end device is a D2D measurement signal, and the measurement signal from the sending end device to the network side device is a D2G measurement signal. The D2D measurement signal is a measurement signal for measuring the channel quality of the D2D link between the UE and the UE in D2D communication. The D2G measurement signal is a measurement signal for measuring the channel quality of the D2G link between the UE and the network side device in wireless communication. The specific content and form of the D2D measurement signal and the D2G measurement signal are not limited in the embodiments of the present application.

For convenience of description, in the embodiment of the present application, a measurement signal from a sending end device to a measurement end device is referred to as a first measurement signal, and a measurement signal from the sending end device to a network side device is referred to as a second measurement signal. When the measurement configuration information in S401 configures to send the first measurement signal and the second measurement signal, the first measurement signal may be one piece of information, or may be multiple pieces of information, which is not specifically limited in this embodiment of the application.

For example, the measurement Signal may be a Sounding Reference Signal (SRS) Signal, or the measurement Signal may be a Demodulation Reference Signal (DMRS). The embodiment of the present application does not specifically limit the form and type of the measurement signal, and all the measurement signals whose functions can be used as measurement signals are what is called in the present application.

It should be noted that, in practical applications, the measurement signals corresponding to the first measurement signal and the second measurement signal may be the same type of reference signal or different types of reference signals, which is not specifically limited in this embodiment of the application.

S402, the sending end equipment receives the measurement configuration information sent by the network side equipment.

It should be noted that the measurement configuration information in S402 is the same as the measurement configuration information in S401. For the measurement configuration information, detailed description has already been made in S401, and details are not repeated here.

S403, if the sending end device needs to send the first measurement signal and the second measurement signal at time t, the sending end device sends the first measurement signal or the second measurement signal at time t.

The sending-end device needs to send the first measurement signal and the second measurement signal at time t, which means configured to send, but does not necessarily need to send.

Optionally, in a possible implementation manner, the time at which the sending-end device is configured to send the first measurement signal and/or the second measurement signal may be configured by measurement configuration information, and the sending-end device may determine according to the measurement configuration information. Specifically, in S403, the sending-end device first determines whether the first measurement signal and the second measurement signal need to be sent at time t according to the measurement configuration information sent by the network-side device received in S402, and if the first measurement signal and the second measurement signal need to be sent at time t, collision of the measurement signals occurs. Specifically, the time domain information in the measurement configuration information determines the time at which the measurement signal is transmitted. When it is judged that the measurement configuration information configuration sending end device needs to send the first measurement signal and the second measurement signal at the time t, the sending end device is executed to send the first measurement signal or the second measurement signal at the time t.

Optionally, in a possible implementation manner, the time at which the sending-end device is configured to send the first measurement signal and/or the second measurement signal may be specified by a protocol executed by the communication device, and the sending-end device may determine the time at which the measurement signal is sent according to the protocol executed by the sending-end device.

For example, the protocol executed by the sending end device may specify that the first measurement signal is periodically sent, and the second measurement signal is non-periodically sent (the sending end device is notified of sending through the physical channel), the sending time triggered by the non-periodicity may be calculated according to a certain rule (for example, at a certain time after receiving the corresponding physical channel), and the sending end device may determine the time t according to the sending period of the first measurement signal and the sending time of the second measurement signal specified by the protocol.

It should be noted that the time t only refers to a time when both the first measurement signal and the second measurement signal need to be transmitted, and is not a specific time. The processes of executing the scheme of the present application are the same at each collision time of the first measurement signal and the second measurement signal, so that only the processing process at time t is described in this embodiment of the present application, and each collision time of the first measurement signal and the second measurement signal can be regarded as time t, and the same operation is performed, which is not described in detail herein.

It should be noted that, in the embodiment of the present application, details of a process of determining, by the sending-end device, whether to send the first measurement signal and the second measurement signal at time t according to the measurement configuration information or the protocol specification are not repeated.

Of course, in S403, at time t when it is determined that the sending-end device needs to send the first measurement signal and the second measurement signal, whether the sending-end device sends the first measurement signal or the second measurement signal is not specifically limited in this embodiment of the present application, and the sending-end device may be configured according to actual requirements.

Optionally, as to the execution process of S403, the sending end device may actively execute the execution process, or the network side device may instruct the sending end device to execute the execution process, which is not specifically limited in this embodiment of the present application, and specifically includes the following two implementation manners:

in implementation 1, the sending-end device actively executes S403.

In implementation manner 1, a communication standard executed by the sending end device may define that the sending end device only sends the first measurement signal or the second measurement signal when determining that the sending end device needs to send the first measurement signal and the second measurement signal.

Further optionally, in implementation mode 1, before the sending-end device actively executes S403, the sending-end device may further notify the network-side device of a processing scheme of the network-side device during collision, and therefore, as shown in fig. 5, after S402 and before S403, the measurement method provided in the embodiment of the present application may further include S402 a.

S402a, the sending end device sends an indication message to the network side device.

The indication message is used for indicating a transmission scheme executed by the sending end device at a time when the sending end device needs to send the first measurement signal and the second measurement signal. For example, the indication message may be used to indicate the measurement signal transmitted by the sending end device in S403, so that the sending end device notifies the network side device of a transmission scheme that the sending end device performs at a time when the sending end device needs to transmit the first measurement signal and the second measurement signal.

It should be noted that the transmission scheme performed by the sending-end device at the time when the sending-end device needs to transmit the first measurement signal and the second measurement signal may include transmitting the first measurement signal, transmitting the second measurement signal, or not transmitting the measurement signal. The specific scheme may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

In implementation 2, the network side device instructs the sending end device to execute S403.

In implementation 2, as shown in fig. 6, after S402 and before S403, the embodiment of the present application may further include S403a and S403 b.

S403a, if the sending-end device needs to send the first measurement signal and the second measurement signal at time t, the network-side device sends a sending instruction for instructing sending the measurement signal to the sending-end device.

The sending instruction is used for instructing the sending end device to send the first measurement signal or the second measurement signal at the time when the first measurement signal and the second measurement signal need to be sent.

S403b, the sending end device receives the sending instruction sent by the network side device.

Corresponding to S403b, in implementation 2, in S403, the sending-end device sends the first measurement signal or the second measurement signal at time t, which may specifically be implemented as: the sending end equipment sends the first measurement signal or the second measurement signal at the time t according to the indication of the sending indication sent by the network side equipment.

Optionally, a possible implementation manner is provided, in S403, if the sending end device needs to send the first measurement signal and the second measurement signal at time t, the sending end device stops sending the measurement channel at time t. The sending end device may actively execute to stop sending the measurement channel at time t, or may execute to stop sending the measurement channel at time t according to an instruction of the network side device. The sending end device actively executes a processing scheme for stopping sending the measurement channel at the time t, and then can send an indication message to the network side device to indicate the sending end device to measure the signal collision. Therefore, the above description in S403 is also applicable to the scheme that if the sending end device needs to send the first measurement signal and the second measurement signal at the time t, the sending end device stops sending the measurement channel at the time t, and details are not repeated here.

S404, the measuring terminal equipment receives the measurement configuration information sent by the network side equipment.

It should be noted that the measurement configuration information in S404 is the same as the measurement configuration information in S401. For the measurement configuration information, detailed description has already been made in S401, and details are not repeated here.

S405, if the sending end equipment needs to send the first measurement signal and the second measurement signal at the moment t, the measuring end equipment measures the first measurement signal or the second measurement signal at the moment t to obtain a measurement result of the measurement signal; or, if the sending end device needs to send the first measurement signal and the second measurement signal at time t, the measuring end device stops measuring the measurement signal at time t.

Optionally, in a possible implementation manner, the time at which the sending-end device is configured to send the first measurement signal and/or the second measurement signal may be configured by the measurement configuration information, and the measuring-end device may determine the time t in S405 according to the measurement configuration information. In S405, the measurement-side device first determines, according to the measurement configuration information received in S404 and sent by the network-side device, whether the measurement configuration information configures that the sending-side device needs to send the first measurement signal and the second measurement signal at time t. Specifically, the time domain information in the measurement configuration information may determine the time when the measurement signal is transmitted.

Optionally, in a possible implementation manner, the time at which the sending-end device is configured to send the first measurement signal and/or the second measurement signal may be specified by a protocol executed by the communication device, the measuring-end device and the sending-end device execute the same protocol, and the measuring-end device may determine the time at which the sending-end device sends the measurement signal according to the protocol executed by the measuring-end device.

For example, the protocol rule executed may be that the first measurement signal is periodically transmitted, and the second measurement signal is non-periodically transmitted (the transmitting end device is notified of transmission through the physical channel), the transmission time triggered by the non-periodicity may be calculated according to a certain rule (for example, at a certain time after receiving the corresponding physical channel), and the transmitting end device may determine the time t according to the transmission period of the first measurement signal and the transmission time of the second measurement signal specified by the protocol.

In S405, if it is determined that the sending-end device needs to send the first measurement signal and the second measurement signal at time t, a collision of the measurement signals occurs, and when the measuring-end device determines that the sending-end device needs to send the first measurement signal and the second measurement signal at time t, the measuring-end device performs measurement of sending the first measurement signal or the second measurement signal at time t or stopping measurement of the measurement signals.

It should be noted that stopping measurement of the measurement signal is a global description, which means that the measurement-side device should perform measurement of the measurement signal at time t according to the measurement configuration information, but the measurement-side device does not perform measurement of the measurement signal at time t because the measurement signal collides at time t.

It should be noted that, in the embodiment of the present application, no details are given to the process of determining, by the measurement end device, whether the sending end device sends the first measurement signal and the second measurement signal at the time t according to the measurement configuration information or the protocol specification.

Optionally, in S405, as for the measurement-side device that measures the first measurement signal or the second measurement signal at the time t, or stops measuring the measurement signal at the time t, this is not specifically limited in this embodiment of the application, and may be configured according to actual requirements.

Of course, for the collision time at which the measurement-side device determines that the transmission-side device transmits the first measurement signal and the second measurement signal simultaneously, the measurement-side device measures whether the first measurement signal or the second measurement signal is the measurement signal transmitted by the transmission-side device at the time of determining that the measurement signal collides in S405.

Optionally, an optional scheme may be that, when the sending end device sends the second measurement signal in S403, the measuring end device, in S405, performs measurement for stopping the measurement signal at time t when it is determined that the sending end device needs to send the first measurement signal and the second measurement signal at time t.

Of course, an optional scheme may be that, no matter what kind of measurement signal is sent by the sending end device in S403, in S405, the measuring end UE performs measurement for stopping the measurement signal at time t when determining that the sending end device needs to send the first measurement signal and the second measurement signal at time t.

The measurement result of the measurement signal may include channel state information, CSI, information of the measurement signal measured by the measurement-side device. The CSI information is a conversion indicator of the signal-to-noise ratio. Optionally, the CSI information may include information such as CQI, PMI, RI, and the like. The measurement result of the measurement signal from the sending end device to the measurement end device can uniquely determine the channel quality of the link between the sending end device and the measurement end device; the measurement result of the measurement signal from the sending end device to the network side device may be adapted to determine the channel quality of the link between the sending end device and the measurement end device according to the difference between the links from the sending end device to the measurement end device and from the sending end device to the network device. The process of determining the channel quality is not described in detail in the embodiments of the present application.

Optionally, as to the execution process of S405, the measurement end device may actively execute the execution process, or the network side device may instruct the measurement end UE to execute the execution process, which is not specifically limited in this embodiment of the present application, and specifically includes the following two implementation manners:

in implementation a, the measurement-side device actively executes S405.

In implementation a, it may be defined by a communication standard executed by the measurement-side device, and the measurement-side device executes the process of S405 when determining a collision time at which the sending-side device needs to send the first measurement signal and the second measurement signal.

In implementation B, the network side device instructs the measurement side device to execute S405.

In implementation B, as shown in fig. 5, after S404 and before S405, the embodiment of the present application may further include S405a and S405B.

S405a, if the sending-end device needs to send the first measurement signal and the second measurement signal at time t, the network-side device sends a measurement instruction to the measuring-end device.

The measurement instruction is used for instructing the measurement end device to measure the first measurement signal or measure the second measurement signal or stop the measurement of the measurement signal at the time when the transmission end device needs to transmit the first measurement signal and the second measurement signal.

Further optionally, in S405a, the network side device may actively execute S405a, or execute S405a according to the instruction of the sender device.

Optionally, when the step S405a is executed by the network side device according to the instruction of the sender device, as shown in fig. 5, after step S402a and before step S405a, the measurement method provided in the embodiment of the present application may further include step S405a1 and step S405a2, corresponding to step S402 a.

S405a1, the network side device receives the indication message sent by the sending end device.

S405a2, the network side equipment determines the measurement indication according to the indication message.

For example, in S402a, the sending-end device is instructed to send the first measurement signal in S403 when the configuration information configures that the sending-end device needs to send the first measurement signal and the second measurement signal at time t, in S405a2, the network-side device determines, according to the instruction message, that the measurement instruction sent to the measuring-end device in S405 is used for instructing the measuring-end device, and measures the first measurement signal at the time when the configuration information configures that the sending-end device needs to send the first measurement signal and the second measurement signal.

For example, if the indication message sent by the sending end device to the network side device in S402a indicates that the sending end device sends the second measurement signal in S403 when the configuration information configures the sending end device to need to send the first measurement signal and the second measurement signal at time t, in S405a2, the network side device determines, according to the indication message, that the measurement indication sent to the measuring end device in S405 is used for indicating the measuring end device, and measures the second measurement signal or stops measuring the measurement signal at the time when the configuration information configures the sending end device to need to send the first measurement signal and the second measurement signal.

The above example is only an exemplary illustration of the network side device executing S405a2, and is not a limitation on the execution process of S405a 2.

S405b, the measurement end equipment receives the measurement instruction sent by the network side equipment.

Corresponding to S405B, in implementation B, in S405, the measuring end device measures the first measurement signal or the second measurement signal or stops measurement of the measurement signal at time t, which may specifically be implemented as: and the measuring end equipment measures the first measuring signal or the second measuring signal or stops measuring signals at the time t according to the measurement instruction.

It should be noted that, the form and content of the indication information, the measurement indication, the sending indication, and the like described in the embodiment of the present application may be configured according to actual requirements, and this is not specifically limited in the embodiment of the present application. The content described in the embodiments of the present application is the relevant content as long as the function is the same as the instruction information, the measurement instruction, the transmission instruction, and the like described in the embodiments of the present application.

It should be further noted that, after S401, the sending end device executes S402 and S403, the measuring end device executes S404 and S405, and actions of the sending end device and the measuring end device may be executed simultaneously or sequentially.

According to the measurement method, when the first measurement signal and the second measurement signal collide in equipment communication, the sending end equipment only sends the first measurement signal or the second measurement signal at the collision moment, the measurement end equipment only measures the first measurement signal or the second measurement signal at the collision moment, or the measurement end equipment stops measuring the measurement signal at the collision moment, and under the condition that an equipment communication framework is not changed, the problem of collision of the measurement signals is solved.

Further optionally, after the measurement end device measures the measurement signal, the channel quality of the link may be determined according to the measurement result. Optionally, after S405, as shown in fig. 7, the measurement method provided in the embodiment of the present application may further include S406 to S408.

S406, the measuring end equipment sends the measuring result of the measuring signal to the network side equipment.

In S406, the measurement end device reports the measurement result of the measurement signal to the network side device, and the network side device determines the channel quality of the link between the sending end device and the measurement end device according to the measurement result of the measurement signal.

Optionally, if the measurement result of the measurement end device in S405 is the first measurement signal, that is, the measurement signal is the measurement signal from the sending end device to the measurement end device, and the measurement result of the measurement signal is the measurement result of the first measurement signal, the network side device may directly determine the channel quality of the link between the sending end device and the measurement end device according to the measurement result of the first measurement signal.

Optionally, if the measurement end device measures the second measurement signal in S405, that is, the measurement end device measures the measurement signal from the transmission end device to the network side device, and the measurement result of the measurement signal is the measurement result of the second measurement signal, as shown in fig. 7, after S405, the measurement method provided in the embodiment of the present application may further include S406 a.

S406a, the measuring end equipment sends power information to the network side equipment.

The power information is used for determining the link difference between the measurement end device and the sending end and between the sending end device and the network side device. The network side equipment adapts to the difference between the two links according to the difference between the two links and the measurement result of the measurement signal, and the channel quality of the link from the sending end equipment to the measurement end equipment can be determined.

It should be noted that S406a and S406 may be executed simultaneously, sequentially, or sent in the same message, which is not specifically limited in this embodiment of the application, and fig. 7 is only an illustration and does not limit the execution sequence of S406a and S406.

Specifically, the link difference may be generally embodied by a power difference. Illustratively, the power information may include, but is not limited to, the following seven power information types:

the type 1 of the power information, the received power of the second measurement signal received by the measurement-side device, or the received power spectrum.

The network side device may obtain a link difference between the measurement end device and the transmission end and between the transmission end device and the network side device, that is, a difference between the received powers or a difference between the received power spectrums, according to the power information type 1 and the expected received power or the received power spectrum of the configured first measurement signal. In the power information type 1, the received power or the received power spectrum of the second measurement signal is actually measured and obtained by the measurement-side device.
