The 5th generation mobile communication technology (5G) system is also called New Radio (NR) system.

The 5G system supports a higher bandwidth, for example, the 5G system supports a high frequency bandwidth of 6G or more in addition to a bandwidth compatible with a Long Term Evolution (LTE) system, and meanwhile, in order to overcome the problem of the anti-attenuation capability of a high frequency signal, the 5G system further introduces a multi-beam (beam) technology, that is, a plurality of different beams cover the whole cell, and each beam covers a smaller range.

When the mobile communication system manages the terminal, the terminal needs to measure some specific signals (such as reference signals) sent by the access network device, and in the related art, when the terminal measures the signals, the measurement process of the signals is usually performed according to a certain measurement period over the full bandwidth sent by the access network device.

Since the 5G system supports a wider bandwidth and more beams, according to the measurement method in the related art, the terminal needs to measure the signal over the full bandwidth of each beam, and the measurement process needs to consume a longer measurement time and hardware resources, resulting in a lower measurement efficiency on the signal.

Referring to fig. 1, a schematic structural diagram of a mobile communication system according to an embodiment of the present invention is shown. The mobile communication system may be a 5G system, also called NR system. The mobile communication system includes: access network device 120 and terminal 140.

Access network device 120 may be a base station. For example, the base station may be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the access network device 120 adopts a centralized distributed architecture, it generally includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A Packet Data Convergence Protocol (PDCP) layer, a Radio Link layer Control Protocol (RLC) layer, and a Media Access Control (MAC) layer are provided in the central unit; the distribution unit is provided with a Physical (PHY) layer protocol stack, and the embodiment of the present invention does not limit the specific implementation manner of the access network device 120.

The access network device 120 and the terminal 140 establish a wireless connection over a wireless air interface. Optionally, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a New Radio (NR); alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.

The terminals may communicate with one or more core networks via a Radio Access Network (RAN), and the terminals 140 may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices. For example, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Equipment (User Terminal), a User Agent (User Agent), a User Device (User Device), or a User Equipment (User Equipment).

It should be noted that, in the mobile communication system shown in fig. 1, a plurality of access network devices 120 and/or a plurality of terminals 140 may be included, and fig. 1 illustrates one access network device 120 and one terminal 140, but this embodiment is not limited thereto.

In a 5G system, two or more different signals may be used to achieve the same function. In the scheme shown in the embodiment of the invention, when the same function is realized, for two different signals which can independently realize the function, the terminal can realize the function by the cooperative measurement of the two signals without respectively carrying out full-bandwidth and/or full-beam measurement on the two signals, so that the frequency of signal measurement is reduced, the measurement time required by the signal measurement is reduced, the hardware resource consumption is reduced, and the signal measurement efficiency is improved. The measurement period, the reporting content, the reporting trigger and the measurement trigger of the two signals can be cooperated.

For example, in the LTE system, a Synchronization Signal (SS) is mainly used for downlink Synchronization, and in the 5G system, the SS is extended to a Synchronization Signal block (SS block), and the Synchronization Signal block may include other signals, signals or information besides a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSs), for example, an NR-Physical Broadcast Channel (NR-PBCH) may be included in the SS block.

Wherein, each signal in the SS block is separately deployed in a time domain, for example, may be distributed on a plurality of consecutive OFDM (Orthogonal Frequency Division Multiplexing) symbols. For example, please refer to fig. 2, which shows a distribution diagram of an SS block according to an embodiment of the present invention. As shown in fig. 2, (a) shows that one SS block includes PSS, SSs, and PBCH, and among three consecutive OFDM symbols, PSS is located at a first OFDM symbol, SSs is located at a second OFDM symbol, and PBCH is located at a third OFDM symbol; (b) the figure shows that one SS block comprises PSS, SSS and PBCH, and in three continuous OFDM symbols, PSS is positioned at the first OFDM symbol, PBCH is positioned at the second OFDM symbol, and SSS is positioned at the third OFDM symbol; (c) the figure shows that one SS block comprises PSS, SSs and PBCH, and in four consecutive OFDM symbols, PSS is located at the first OFDM symbol, SSs is located at the second and fourth OFDM symbols, PBCH is located at the third OFDM symbol; (d) the figure shows that one SS block comprises PSS and SSs, and in two consecutive OFDM symbols, PSS is located at the first OFDM symbol and SSs is located at the second OFDM symbol.

Alternatively, the signals in the SS block may be distributed over non-consecutive OFDM symbols, for example, different signals of one SS block are respectively located in different slots, and in the same slot, signals belonging to different SS blocks are respectively located on different OFDM symbols. For example, please refer to fig. 3, which shows a distribution diagram of another SS block according to an embodiment of the present invention. In fig. 3, one SS block includes PSS, SSs, and PBCH; the PSS of SS block #1 is located in the third OFDM symbol on the first slot, the SSS of SS block #1 is located in the third OFDM symbol on the second slot, and the PBCH of SS block #1 is located in the third OFDM symbol on the third slot; the PSS of SS block #2 is located in the fourth OFDM symbol on the first slot, the SSS of SS block #2 is located in the fourth OFDM symbol on the second slot, and the PBCH of SS block #2 is located in the fourth OFDM symbol on the third slot; the PSS of SS block #3 is located at the fifth OFDM symbol on the first slot, the SSs of SS block #3 is located at the fifth OFDM symbol on the second slot, and the PBCH of SS block #3 is located at the fifth OFDM symbol on the third slot.

Optionally, in the 5G system, the SS block may also contain other information, such as timing information.

In a 5G system, all or part of the signals in the SS block may be used for other functions besides signal synchronization, for example, for signal quality measurement. In 5G systems, the signal quality may also be measured by measuring other signals, for example, by measuring CSI-RS signals. The measurement of the signal quality may be used to implement downlink Beam Management (DL Beam Management) and/or Mobility Management (MM) for the terminal. Therefore, in the 5G system, when performing downlink beam management, measurement may be performed on part or all of signals in the SS block, or measurement may be performed on the CSI-RS, and similarly, in mobility management, measurement may be performed on part or all of signals in the SS block, or measurement may be performed on the CSI-RS.

The embodiment of the invention takes the measurement of part/all signals in an SS block or CSI-RS to realize downlink beam management or mobility management as an example, and introduces the scheme related to the embodiment of the invention.

In one possible implementation manner, when a certain function is implemented, two signals capable of implementing the function may be measured respectively according to different periods. For example, the terminal performs at least one measurement procedure of a first signal transmitted to the access network device at a first period, and further performs at least one measurement procedure of a second signal transmitted to the access network device at a second period, wherein a measurement result of the at least one measurement procedure of the first signal and a measurement result of the at least one measurement procedure of the second signal by the terminal are used to implement the same function.

Referring to fig. 4, a flowchart of a method for signal measurement according to an embodiment of the present invention is shown. The embodiment is exemplified by applying the signal measurement method to the mobile communication system shown in fig. 1, and measuring all or part of signals in the SS block and CSI-RS signals. The method comprises the following steps:

in step 401, the terminal performs at least one measurement procedure on a first signal transmitted by an access network device at a first cycle on a first bandwidth.

In the 5G system, a configuration related to measurement relates to factors such as a measured signal, a measurement period, a reporting period, and a use purpose, and the above parameters may be regarded as different measurement processes if they are different, so in the embodiment of the present invention, measurement of a CSI-RS/SS block signal may be divided into different measurement processes, different measurement processes may be provided for a signal of the same type, and different measurement processes for a signal of the same type may be used for different purposes.

In step 402, the terminal performs at least one measurement procedure on a second signal transmitted by the access network device at a second period on a second bandwidth.

The first signal can be part or all of signals in the SS block, and the second signal is a CSI-RS; or the first signal is a CSI-RS, and the second signal is part or all of the SS block.

The first bandwidth and the second bandwidth are different bandwidths, or the first bandwidth and the second bandwidth are the same bandwidth; the first period and the second period may be periods having the same duration, or may be periods having different durations.

For example, referring to fig. 5, taking two signals as a part or all of the SS block and CSI-RS as examples, it shows a schematic diagram of measurement periods of 5 different signals according to an embodiment of the present invention.

In fig. 5(a), the measurement period of the terminal for the CSI-RS is an integer multiple (2 times) of the measurement period for some or all signals in the SS block, and the terminal performs one measurement on the corresponding signal in each measurement period, wherein the measurement time instants of the terminal for the two signals may be aligned, i.e. t₁And t₇The same, or the measurement instants of the two signals by the terminal may be misaligned, i.e. t₁And t₇Different.

In fig. 5(b), the measurement period of some or all signals in the SS block by the terminal is an integer multiple (2 times) of the measurement period of the CSI-RS, and the terminal performs one measurement on the corresponding signal in each measurement period, and accordingly, the measurement time instants of the two signals by the terminal may be aligned, i.e., t₁And t₇The same, or the measurement instants of the two signals by the terminal may be misaligned, i.e. t₁And t₇Different.

In fig. 5(c), the measurement period of part or all of the signals in the SS block by the terminal is the same as the measurement period of the CSI-RS, and the terminal performs one measurement on part or all of the signals in the SS block and performs multiple measurements on the CSI-RS in each measurement period; and, the time of performing one measurement on part or all of the signals in the SS block is prior to the time of performing multiple measurements on the CSI-RS.

In fig. 5(d), the measurement period of some or all signals in the SS block by the terminal is the same as the measurement period of the CSI-RS, and the terminal performs multiple measurements on some or all signals in the SS block and performs one measurement on the CSI-RS in each measurement period; and the time for measuring part or all of the signals in the SS block for a plurality of times is after the time for measuring the CSI-RS for one time.

In fig. 5(d), the terminal has the same measurement period for some or all signals in the SS block as the measurement period for the CSI-RS, and in each measurement period, the terminal performs multiple measurements for some or all signals in the SS block and performs multiple measurements for the CSI-RS; and the time for measuring the CSI-RS for a plurality of times is between the adjacent times of measuring some or all signals in the SS block.

In step 403, the terminal implements downlink beam management or mobility management according to the measurement result of the at least one measurement procedure on the first signal and the measurement result of the at least one measurement procedure on the second signal.

Optionally, the measurement result of the at least one measurement procedure for the first signal by the terminal and the measurement result of the at least one measurement procedure for the second signal by the terminal are used to implement the same function, for example, both are used to implement downlink beam management or mobility management.

Specifically, for example, the first signal is all or part of the SS block, the first bandwidth is a narrow bandwidth, such as 5MHz, and the second signal is CSI-RS, and the second bandwidth is a wide bandwidth, such as 20 MHz. Taking the case of fig. 5(a) as an example, when the data amount of the data that the terminal needs to transmit is small, the terminal only needs to occupy less bandwidth to meet the transmission requirement, and at this time, in the downlink beam management or mobility management process, the terminal may perform, at a higher frequency, a measurement process on at least one of all or part of signals in the SS block at the first bandwidth of 5MHZ to implement the downlink beam management or mobility management; meanwhile, in order to be able to know information such as channel quality on other bandwidths, the terminal may perform at least one measurement procedure of the CSI-RS for implementing downlink beam management or mobility management at a lower frequency on a second bandwidth of 20 MHZ. By the method, the terminal does not need to maintain the high-frequency measurement of the signal on a wider broadband, so that unnecessary measurement processes are reduced, the measurement performance is ensured, the times of signal measurement are reduced, the measurement time required by the signal measurement is reduced, the hardware resource consumption is reduced, and the measurement efficiency is improved.

Further, taking the case of fig. 5(b) as an example, when the data amount of the data that the terminal needs to transmit is large, the terminal only needs to occupy more bandwidth to meet the transmission requirement, at this time, in the downlink beam management or mobility management process, the terminal may perform, at a higher frequency, a measurement process on at least one of CSI-RSs for implementing the downlink beam management or mobility management on the second bandwidth of 20MHZ, and at a lower frequency, on the first bandwidth of 5MHZ, the terminal performs a measurement process on at least one of all or part of signals in the SSblock for implementing the downlink beam management or mobility management on the first bandwidth of 5 MHZ. By the method, the terminal can reduce unnecessary measurement processes on the narrow bandwidth, reduce the times of signal measurement and improve the measurement efficiency while ensuring the measurement performance.

Alternatively, in another possible scenario, the first signal may be a CSI-RS, the first bandwidth is a narrow bandwidth, such as 5MHz, and the second signal may be all or part of the SS block, and the second bandwidth is a wide bandwidth, such as 20 MHz. When the data volume of the data required to be transmitted by the terminal is small, in the downlink beam management or mobility management process, the terminal may perform a measurement process on at least one of all or part of signals in the CSI-RS at a higher frequency on a first bandwidth of 5MHZ, to implement the downlink beam management or mobility management; meanwhile, the terminal may perform a measurement procedure for at least one of all or part of the signals in the SS block at a lower frequency on a second bandwidth of 20MHZ to implement downlink beam management or mobility management.

When the data volume of the data required to be transmitted by the terminal is large, the terminal may perform, in the downlink beam management or mobility management process, at a higher frequency, a measurement process on at least one of all or part of signals in the SS block for implementing the downlink beam management or mobility management on the second bandwidth of 20MHZ, and perform, in the first bandwidth of 5MHZ, a measurement process on at least one of the CSI-RSs for implementing the downlink beam management or mobility management on the first bandwidth of 5 MHZ.

Alternatively, the first period and the second period may be cyclic periods over a full time period, that is, the terminal measures the first signal at the first period and measures the second signal at the second period in any time period.

Alternatively, the first period and the second period may be a cyclic period over a partial time period, that is, the terminal measures the first signal with the first period and measures the second signal with the second period only over the partial time period. The partial time period may be a time period pre-configured in the terminal, or may be a time period indicated by a system (such as an access network device).

In summary, in the method shown in the embodiment of the present invention, the terminal performs cooperative measurement on two different signals in a certain management process, so as to reduce unnecessary measurement processes, and reduce the number of signal measurements while ensuring measurement performance, thereby achieving the effects of reducing measurement time required for signal measurement, reducing hardware resource consumption, and improving measurement efficiency.

Referring to fig. 6, a flowchart of a method for signal measurement according to an embodiment of the present invention is shown. The embodiment is exemplified by applying the signal measurement method to the mobile communication system shown in fig. 1, and measuring all or part of signals in the SS block and CSI-RS signals. The method comprises the following steps:

step 601, the terminal performs at least one measurement process of a first signal transmitted to the access network device on a first beam with a first period.

In step 602, the terminal performs at least one measurement procedure of a second signal transmitted to the access network device at a second period on a second beam.

Wherein the first beam and the second beam are different types of beams, or the first beam and the second beam are the same beam; the first period and the second period may be periods having the same duration, or may be periods having different durations.

For example, taking two signals as a part or all of the SS block and CSI-RS as examples, a schematic diagram of measurement periods of different signals can be shown in fig. 5.

Step 603, the terminal implements downlink beam management or mobility management according to the measurement result of the at least one measurement process of the first signal and the measurement result of the at least one measurement process of the terminal on the second signal.

Specifically, for example, the first signal is all or part of the signals in the SS block, the first beam is a narrower beam, the second signal is a CSI-RS, and the second beam is a wider beam; wherein one second beam may cover a plurality of first beams. Taking the case of fig. 5(a) as an example, when the terminal has a slow moving speed and is close to stationary, the terminal only needs to occupy one narrow beam, and at this time, in the downlink beam management or mobility management process, the terminal may perform a measurement process on at least one of all or part of signals in the SS block at a higher frequency on the first beam to implement the downlink beam management or mobility management; meanwhile, in order to be able to know information such as channel quality on other wide beams corresponding to the second beam for subsequent beam switching, the terminal may perform at least one measurement procedure for implementing downlink beam management or mobility management on the CSI-RS at a lower frequency on the second beam. By the method, the terminal does not need to maintain the high-frequency measurement of the signals on the wider wave beam, so that unnecessary measurement processes are reduced, the measurement performance is ensured, and meanwhile, the frequency of signal measurement is reduced, so that the effects of reducing the measurement time required by the signal measurement, reducing the consumption of hardware resources and improving the measurement efficiency are achieved.

Further, taking the case of fig. 5(b) as an example, when the terminal moves faster, the terminal may move out of the range corresponding to the current narrow beam quickly, and at this time, in order to avoid frequent beam switching, in the downlink beam management or mobility management process, the terminal may perform, on the second beam, at a higher frequency, a measurement process for at least one of CSI-RSs to implement downlink beam management or mobility management, and, on the first beam, the terminal may perform, on a lower frequency, a measurement process for at least one of all or part of signals in the SS block to implement downlink beam management or mobility management. By the method, the terminal can reduce unnecessary measurement processes on the narrow beam, reduce the times of signal measurement and improve the measurement efficiency while ensuring the measurement performance.

Alternatively, in another possible scenario, the first signal may also be a CSI-RS, the first beam is a narrower beam, and the second signal may be all or part of the signal in the SS block, and the second beam is a wider beam. When the terminal is moving at a low speed or close to a standstill, in a downlink beam management or mobility management process, the terminal may perform a measurement process on at least one of all or part of signals in the CSI-RS at a higher frequency on the first beam to implement the downlink beam management or mobility management; meanwhile, the terminal may perform, on the second beam, a measurement procedure for implementing downlink beam management or mobility management on at least one of all or part of signals in the SS block at a lower frequency.

When the terminal moves faster, the terminal may perform, on the second beam, a measurement process for implementing downlink beam management or mobility management on at least one of all or part of signals in the SS block at a higher frequency in a downlink beam management or mobility management process, and on the first beam, the terminal performs, on a lower frequency, a measurement process for implementing downlink beam management or mobility management on at least one of the CSI-RSs.

Optionally, the first period and the second period may be a cycle period over a full time period, or may be a cycle period over a partial time period.

In a possible implementation manner, when a certain management process is implemented, the terminal may first perform a measurement process on a certain signal, and when a certain condition is satisfied, start a measurement process on another signal, without simultaneously measuring two different signals for a management process. For example, the terminal performs at least one measurement process of a first signal sent to the access network device, and when the parameter information corresponding to the terminal meets a preset condition, the terminal starts at least one measurement process of a second signal sent to the access network device.

Referring to fig. 7, a flowchart of a method for signal measurement according to an embodiment of the invention is shown. The embodiment is exemplified by applying the signal measurement method to the mobile communication system shown in fig. 1, and measuring all or part of signals in the SS block and CSI-RS signals. The method comprises the following steps:

in step 701, the terminal performs at least one measurement procedure on a first signal transmitted by the access network device over a first bandwidth.

The parameter information includes a measurement result of at least one measurement process of a first signal sent by the terminal to the access network device, and/or the parameter information includes a terminal state of the terminal.

Optionally, the terminal status may include at least one of a moving speed, network configuration information, a service type, and a transmission mode.

Step 702, when the parameter information satisfies a preset condition, the terminal starts at least one measurement process of a second signal sent by the access network device on a second bandwidth.

Wherein the first bandwidth and the second bandwidth are different bandwidths or the first bandwidth and the second bandwidth are the same bandwidth.

Optionally, when the terminal detects that the parameter information satisfies the preset condition, the terminal may start at least one measurement process of a second signal sent by the access network device on a second bandwidth.

When the parameter information includes a measurement result of at least one measurement process of a first signal transmitted by the access network device, the preset condition may be that a channel quality obtained by measuring the first signal is lower than a preset quality threshold.

When the parameter information includes a terminal state of the terminal, the preset condition may be a condition related to the terminal state. For example, when the terminal state includes a moving speed, the preset condition may include that the moving speed is greater than a first preset speed threshold, or the preset condition may include that the moving speed is less than a second preset speed threshold; when the terminal state includes network configuration information, the preset condition may include that the network configuration information is preset configuration information; when the terminal state includes a service type, the preset condition may include that the service type of the terminal is a preset service type; when the terminal state includes a transmission mode, the preset condition may include that the transmission mode of the terminal is a preset transmission mode.

Optionally, the determining process of the preset condition may be executed by the terminal, and when the terminal detects that the parameter information satisfies the preset condition, the terminal starts at least one measurement process of a second signal sent by the access network device over the second bandwidth.

Alternatively, the determining process of the preset condition may be performed by the access network device, for example, the access network device may collect the parameter information, for example, may receive information reported by the terminal (for example, a measurement result of the terminal reporting the first signal or a measurement result of the terminal moving speed), and/or may query locally configured information (for example, network configuration information, a service type, and a transmission mode), and/or may obtain measured information (for example, the access network device may measure the terminal moving speed), and when the access network device determines that the collected parameter information satisfies the preset condition, the access network device may send a measurement configuration and/or activation instruction to the terminal through a control message, where the measurement configuration and/or activation instruction is used to instruct the terminal to start at least one measurement process on the second signal sent on the second bandwidth, the Control message may include at least one of Radio Resource Control (RRC) signaling, Media Access Control (MAC CE) Information, and Downlink Control Information (DCI). And after receiving the measurement configuration and/or activation instruction, the terminal starts at least one measurement process of the second signal transmitted on the second bandwidth according to the measurement configuration and/or activation instruction.

The measurement configuration may include configuration information about at least one measurement procedure on the second signal, for example, the measurement configuration may include a bandwidth range of measurement, a measurement period, a start-stop time of measurement, and the like; the activation instruction may be used to instruct the terminal to start a corresponding measurement procedure.

The measurement configuration and the activation instruction may be used separately, for example, the terminal does not have a measurement configuration for at least one measurement process of the second signal, and when receiving the measurement configuration, the terminal automatically starts measurement according to the measurement configuration; or, the terminal has preset the measurement configuration of at least one measurement process of the second signal, and when receiving the activation instruction, the terminal starts measurement according to the preset measurement configuration; or after the terminal receives the measurement configuration and the activation instruction, the terminal starts measurement according to the received measurement configuration and activation instruction.

Step 703, the terminal maintains at least one measurement process of the first signal sent to the access network device; alternatively, the terminal stops at least one measurement process of the first signal transmitted by the access network device.

In the embodiment of the present invention, after the terminal starts at least one measurement process for the second signal, the terminal may maintain the original at least one measurement process for the first signal to improve the measurement accuracy, or the terminal may stop at least one measurement process for the first signal to reduce unnecessary measurement times.

For example, after the terminal starts at least one measurement process on the second signal, if the accuracy of the measurement result of the at least one measurement process on the second signal is higher than the predetermined measurement accuracy, the terminal stops at least one measurement process on the first signal sent by the access network device; on the contrary, if the accuracy of the measurement result of the at least one measurement process on the second signal is not higher than the predetermined measurement accuracy, the terminal continues to maintain the at least one measurement process on the first signal transmitted by the access network device.

Specifically, for example, the first signal is all or part of the SS block, the first bandwidth is a narrow bandwidth, such as 5MHz, and the second signal is CSI-RS, and the second bandwidth is a wide bandwidth, such as 20 MHz. In the downlink beam management or mobility management process, the terminal may first perform a measurement process on at least one of all or part of signals in the SS block for implementing downlink beam management or mobility management on a first bandwidth of 5MHZ, and when a measurement result of the terminal on all or part of signals in the SS block and/or parameter information of the terminal satisfy a condition, for example, the measurement result indicates that channel quality obtained by measurement on the first bandwidth is poor and/or a terminal has a fast moving speed, the terminal starts a measurement process on at least one of CSI-RS signals for implementing downlink beam management or mobility management on a second bandwidth of 20MHZ according to a preset configuration or an indication of an access network device.

Alternatively, the first signal is a CSI-RS, the first bandwidth is a narrow bandwidth, such as 5MHz, and the second signal is all or part of an SS block, and the second bandwidth is a wider bandwidth, such as 20 MHz. In the downlink beam management or mobility management process, the terminal may first perform at least one measurement process for the CSI-RS on a first bandwidth of 5MHZ to implement downlink beam management or mobility management, and when a measurement result of the terminal for the CSI-RS and/or parameter information of the terminal satisfy a condition, for example, the measurement result indicates that channel quality obtained by measurement on the first bandwidth is poor, and/or a terminal has a fast moving speed, the terminal starts at least one measurement process for all or part of signals in an SS block to implement downlink beam management or mobility management on a second bandwidth of 20MHZ according to a preset configuration or an indication of an access network device.

Alternatively, the first signal is all or part of the SS block, the first bandwidth is a narrow bandwidth, such as 5MHz, and the second signal is the CSI-RS, and the second bandwidth is a wide bandwidth, such as 20 MHz. In the downlink beam management or mobility management process, the terminal may first perform at least one measurement process for the CSI-RS to implement downlink beam management or mobility management on a second bandwidth of 20MHZ, and when a measurement result of the terminal for the CSI-RS and/or parameter information of the terminal satisfy a condition, the terminal starts at least one measurement process for all or part of signals in the SS block to implement downlink beam management or mobility management on a first bandwidth of 5MHZ according to a pre-configuration or an instruction of an access network device.

Alternatively, the first signal is a CSI-RS, the first bandwidth is a narrow bandwidth, such as 5MHz, and the second signal is all or part of an SS block, and the second bandwidth is a wider bandwidth, such as 20 MHz. In the downlink beam management or mobility management process, the terminal may first perform a measurement process on at least one of all or part of signals in the SS block for implementing downlink beam management or mobility management on a second bandwidth of 20MHZ, and when a measurement result of all or part of signals in the SS block and/or parameter information of the terminal satisfy a condition, the terminal starts a measurement process on at least one of CSI-RS for implementing downlink beam management or mobility management on a first bandwidth of 5MHZ according to a preset configuration or an instruction of an access network device.

Referring to fig. 8, a flowchart of a method for signal measurement according to an embodiment of the invention is shown. The embodiment is exemplified by applying the signal measurement method to the mobile communication system shown in fig. 1, and measuring all or part of signals in the SS block and CSI-RS signals. The method comprises the following steps:

in step 801, the terminal performs at least one measurement procedure on a first signal transmitted by the access network device on a first beam.

Step 802, when the parameter information satisfies a preset condition, the terminal starts at least one measurement process of a second signal sent by the access network device on a second beam.

Wherein the first beam and the second beam are different types of beams, or the first beam and the second beam are the same type of beam.

Optionally, when the parameter information satisfies a preset condition, the terminal may start at least one measurement process of a second signal sent by the access network device on a second beam.

Optionally, the determining process of the preset condition may be executed by the terminal, and when the terminal detects that the parameter information satisfies the preset condition, the terminal starts at least one measurement process of a second signal sent by the access network device on a second beam.

Or, the above-mentioned judging process of the preset condition may also be executed by the access network device, and when the access network device judges that the collected parameter information satisfies the preset condition, the access network device may send a measurement configuration and/or an activation instruction to the terminal through the control message. And after receiving the measurement configuration and/or activation instruction, the terminal starts at least one measurement process of the second signal transmitted on the second beam according to the measurement configuration and/or activation instruction.

Step 803, the terminal maintains at least one measurement process of the first signal sent to the access network device; alternatively, the terminal stops at least one measurement process of the first signal transmitted by the access network device.

Specifically, for example, the first signal is all or part of the SS block, the first beam is a narrower beam, the second signal is a CSI-RS, and the second beam is a wider beam. When the terminal is stationary, it only needs one narrower first beam to meet the transmission requirement, and in the downlink beam management or mobility management process, the terminal may first perform a measurement process on the first beam for implementing downlink beam management or mobility management on at least one of all or part of signals in the SS block, and when the measurement result of the terminal on all or part of signals in the SS block and/or the parameter information of the terminal meet a condition, for example, the measurement result indicates that the channel quality obtained by measurement on the first beam is poor, and/or the terminal has a fast moving speed, the terminal starts a measurement process on the second beam for implementing downlink beam management or mobility management on at least one of CSI-RS signals according to a pre-configuration or an indication of an access network device.

Alternatively, the first signal is a CSI-RS, the first beam is a narrower beam, and the second signal is all or part of the signal in an SS block, the second beam is a wider beam. In a downlink beam management or mobility management process, a terminal may first perform at least one measurement process for a CSI-RS on a first beam for implementing downlink beam management or mobility management, and when a measurement result of the CSI-RS and/or parameter information of the terminal satisfy a condition, for example, the measurement result indicates that channel quality obtained by measurement on the first beam is poor, and/or a terminal has a fast moving speed, the terminal starts at least one measurement process for implementing downlink beam management or mobility management on a second beam for all or part of signals in an SS block according to a preset configuration or an indication of an access network device.

Alternatively, the first signal is all or part of the SS block, the first beam is a narrower beam, and the second signal is a CSI-RS, the second beam is a wider beam. In a downlink beam management or mobility management process, the terminal may first perform at least one measurement process for the CSI-RS on the second beam for implementing downlink beam management or mobility management, and when a measurement result of the CSI-RS and/or parameter information of the terminal by the terminal satisfy a condition, the terminal starts at least one measurement process for implementing downlink beam management or mobility management on at least one of all or part of signals in the SS block on the first beam according to a preset configuration or an instruction of an access network device.

Alternatively, the first signal is a CSI-RS, the first beam is a narrower beam, and the second signal is all or part of the signal in an SS block, the second beam is a wider beam. In the downlink beam management or mobility management process, the terminal may first perform, on the second beam, a measurement process for implementing downlink beam management or mobility management on at least one of all or part of signals in the SS block, and when a measurement result of the terminal on all or part of signals in the SS block and/or parameter information of the terminal satisfy a condition, the terminal starts, according to a preset configuration or an instruction of the access network device, the measurement process for implementing downlink beam management or mobility management on at least one of the CSI-RS on the first beam.

In a possible implementation manner, when a certain management process is implemented, the terminal may start or stop a measurement process for another signal when starting a measurement process for a certain signal, and it is not necessary to measure two different signals simultaneously for one management process.

step 901, the terminal starts at least one measuring process of a first signal sent to the access network equipment;

step 902, the terminal starts or stops at least one measuring process of a second signal sent to the access network device; the at least one measurement of the first signal corresponds to the at least one measurement of the second signal.

Optionally, the terminal may start or stop at least one measurement process of the second signal sent to the access network device by pre-configuration.

When the at least one measurement process of the first signal is activated and started, the terminal automatically starts the at least one measurement process of the second signal according to the pre-configured corresponding relationship.

Optionally, before starting or stopping at least one measurement process of the second signal sent to the access network device, the terminal receives a measurement configuration and/or an activation instruction sent by the access network device; and the terminal starts or stops at least one measuring process of the second signal sent to the access network equipment according to the measuring configuration and/or the activation instruction.

Or, when the terminal activates and starts at least one measurement process of the first signal, the access network device may send a measurement configuration and/or activation instruction to the terminal, and in this embodiment of the present invention, the measurement configuration and/or activation instruction may instruct the terminal to stop at least one measurement process of the second signal sent to the access network device, in addition to instructing the terminal to start at least one measurement process of the second signal sent to the access network device. For example, when the measurement configuration is not empty, the terminal is instructed to start at least one measurement process of the second signal sent to the access network device, and when the measurement configuration is empty, the terminal is instructed to stop at least one measurement process of the second signal sent to the access network device; or, when the activation instruction is 1, instructing the terminal to start at least one measurement process of the second signal sent to the access network device, and when the activation instruction is 0, instructing the terminal to stop at least one measurement process of the second signal sent to the access network device.
