Description

Frequency point measurement method, network side equipment and user terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a frequency point measurement method, a network side device, and a user terminal.

Background

In 5GNR (New Radio), a primary and secondary synchronization signal and PBCH (physical broadcast channel) are carried in SSB (synchronization signal block ), the SSB is periodically transmitted on the frequency domain, and the transmission position can be flexibly configured by the network, and the available frequency point position is identified by GSCN (global synchronization channel number ).

In 5GNR, for the same carrier, when the center frequency points of SSBs of the cell to be measured and the serving cell are the same, the same frequency measurement is performed. The same frequency measurement can be divided into measurement requiring gap (interval) and measurement not requiring gap. When the SSB is included in the BWP (bandwidth part) activated by the serving cell, the measurement type is measurement that the gap is not needed in the same frequency, and when the SSB is not included in the BWP activated by the serving cell, the ue needs to return to the location of the SSB for measurement, and the measurement type is measurement that the gap is needed in the same frequency.

For measurements requiring gap, the network needs to configure the user equipment with measurement gap. Since it cannot be determined whether the BWP currently activated by the ue contains the SSB when the measurement interval information is received, if the BWP does not contain the SSB, the ue needs the gap to perform measurement; if SSB is included in BWP, the ue does not need gap measurement. However, once the gap is configured, it means that the UE stops receiving and transmitting the data of the serving cell in each period gap, and the network will not schedule any data for the UE, resulting in resource waste.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic flow chart of a frequency point measurement method according to an embodiment of the present invention. As shown in fig. 1, a frequency point measurement method is applied to a network side device, and includes the following steps:

step 101, transmitting at least one of the following information for frequency point measurement to a user terminal: characteristic information of the current reference synchronous signal block; and the center frequency point of the synchronous signal block of the service cell where the user terminal is located.

The at least one piece of information for frequency point measurement may be characteristic information of a current reference synchronization signal block, where the characteristic information includes a characteristic of the reference synchronization signal block, and the current reference SSB of the serving cell may be determined according to the characteristic information. For example, the number of the reference SSB or the center frequency point is transmitted to the user terminal. The user terminal can determine the measurement type of the frequency point to be measured according to the current reference SSB.

The network side device may specifically send the current reference SSB to the user terminal by sending measurement configuration information to the user terminal, or may directly send the current reference SSB to the user terminal, which is not limited in this embodiment.

One cell may send multiple SSBs in the frequency domain, as shown in fig. 1a, where the network configures a reference SSB for the terminal, and the measurement of the cell with the same center frequency point of the reference SSB is the same frequency measurement. It is currently specified that a ue can only configure a reference SSB, and the BWP of the ue is flexible in the manner of handoff, which is a relatively dynamic procedure. In the prior art, if BWP is switched to SSB2 and the reference SSB of the ue is still SSB1, the ue will perform measurement in the same-frequency measurement mode requiring interval.

With the scheme in the embodiment of the present invention, as shown in fig. 1b, when BWP is switched to SSB2, the network side device sends the current reference SSB to the user terminal, and updates the reference SSB to SSB2. Because the SSB2 of the service cell and the SSB2 of the neighbor cell have the same center frequency point, the user terminal can measure in the same frequency measurement mode without measuring interval, and the system overhead can be saved.

The at least one information for frequency point measurement may also be a center frequency point of a synchronization signal block of a serving cell where the user terminal is located. The center frequency point of the synchronization signal block may be the center frequency point of all synchronization signal blocks of the serving cell where the user terminal is located. The user terminal can determine the measurement type of the frequency point to be measured according to the obtained center frequency points of all the synchronous signal blocks, namely, whether the measurement interval is needed or not.

For example, as shown in fig. 1c, there are 2 SSBs on the serving cell and 1 SSB on the co-frequency neighbor cell frequency domain. The network side equipment sends configuration information containing the center frequency points of 2 SSBs of the service cell and the center frequency points of 1 SSB of the neighbor cell to be measured to the user terminal.

If the BWP activated by the ue includes SSB1, since the SSB1 of the serving cell and the SSB1 of the neighboring cell have the same center frequency point, the ue may measure the frequency point to be measured according to the measurement type that does not need a measurement interval in the same frequency. The original measurement interval can be invalidated, and the user can send and receive data in the original measurement interval, so that the system overhead can be saved.

In addition, the at least one piece of information for frequency point measurement may also include the characteristic information of the current reference synchronization signal block and the center frequency point of the synchronization signal block of the serving cell where the user terminal is located, and the user terminal may determine the measurement type according to the received information in any one of the manners or determine the measurement type in combination of the two manners. Reference may be made to the foregoing for specific implementation, and details are not repeated here.

According to the embodiment of the invention, the network side equipment sends the information for measuring the frequency points to the user terminal, and the user terminal can determine the type of the frequency points to be measured according to the information of the frequency points to be measured, so that the frequency points to be measured are measured according to the determined type, data transmission does not need to be stopped in a measurement interval of each period, and the resource utilization rate is improved.

Referring to fig. 2, fig. 2 is a schematic flow chart of a frequency point measurement method according to an embodiment of the present invention. As shown in fig. 2, a frequency point measurement method is applied to a network side device, and includes the following steps:

step 201, sending at least one of the following information for frequency point measurement to a user terminal: characteristic information of the current reference synchronous signal block; the center frequency point of the synchronous signal block of the service cell where the user terminal is located; when the at least one piece of information includes characteristic information of a current reference synchronization signal block, the current reference synchronization signal block includes a reference synchronization signal block initially configured for the user terminal and/or an updated reference synchronization signal block when a bandwidth part of the user terminal is switched.

In this embodiment, the current reference synchronization signal block may be a reference synchronization signal block initially configured by the network side device to the user terminal. The ue may determine, according to the reference synchronization signal block configured initially, a measurement type of the frequency point to be measured, that is, whether a measurement interval is required.

When the bandwidth part of the user terminal is switched, if the SSB contained in the newly activated bandwidth part is different from the current reference SSB, the reference synchronization signal block can be updated. Specifically, the network side device may send an indication message for switching the bandwidth part to the user terminal, where the indication message carries the updated characteristic information of the reference SSB, and the user terminal updates the reference SSB when switching the BWP.

In addition, if the newly activated bandwidth portion contains the same SSB as the current reference SSB, or the newly activated bandwidth portion does not contain the SSB, the reference SSB may not be updated.

In this way, the user terminal can determine the measurement type of the cell to be measured according to the updated reference synchronous signal block, and can optimize the measurement mode, thereby saving the system overhead.

Optionally, when the current reference synchronization signal block includes a reference synchronization signal block initially configured for the user terminal, the characteristic information of the current reference synchronization signal block is sent to the user terminal by sending first measurement configuration information to the user terminal, where the first measurement configuration information includes the reference synchronization signal block initially configured for the user terminal.

In this embodiment, the network side device sends first measurement configuration information to the user terminal, where the first measurement configuration information includes reference synchronization signal blocks initially configured by the network side device for the user terminal, where there is one and only one reference synchronization signal block.

The first measurement configuration information may further include a frequency point to be measured, where the frequency point to be measured is a center frequency point of the SSB. From the network side, the cells to be measured can comprise the same-frequency cells and different-frequency cells, and the network side equipment can classify and respectively issue the measurement frequency points of the same-frequency cells and the measurement frequency points of the different-frequency cells. Therefore, the user terminal can reduce the measurement times for the same-frequency cells and save resources. In addition, the first measurement configuration information may further include a configuration of a measurement interval, for example, a period of the measurement interval, a length of the measurement interval, a position of the measurement interval, and the like.

The user terminal can determine the measurement type of the frequency point to be measured according to the information of the reference synchronous signal block and the frequency point to be measured in the first measurement configuration information, and the measurement type can comprise inter-frequency measurement and same-frequency measurement requiring measurement intervals, and the same-frequency measurement requiring no measurement intervals.

The network side equipment transmits the characteristic information of the current reference synchronous signal block to the user terminal while transmitting the measurement configuration information to the user terminal, so that the information transmission efficiency can be improved, and the resource utilization rate can be improved.

Optionally, when the current reference synchronization signal block includes a bandwidth part of the user terminal and the updated reference synchronization signal block, the characteristic information of the current reference synchronization signal block is sent to the user terminal by sending a radio resource control message indicating the bandwidth part to be switched to the user terminal; wherein, the radio resource control message comprises the characteristic information of the updated reference synchronous signal block; or alternatively

Scheduling the bandwidth part switching of the user terminal through the physical layer downlink control message, and sending the characteristic information of the current reference synchronous signal block to the user terminal; the downlink control message comprises the characteristic information of the updated reference synchronous signal block; or alternatively

Transmitting characteristic information of a current reference synchronization signal block to a user terminal by transmitting a radio resource control message including a timer to the user terminal; and the wireless resource control message is used for triggering the bandwidth part switching when the timing time of the timer is reached, and the wireless resource control message comprises the characteristic information of the updated reference synchronous signal block.

In this embodiment, for the bandwidth part switching in different manners, the network-side device may transmit the reference synchronization signal block in different manners.

The first method is to send a radio resource control message indicating the handover of the bandwidth part to the user terminal, wherein the radio resource control message contains the characteristic information of the updated reference synchronization signal block.

And the second is to schedule the user terminal bandwidth part switching by sending a physical layer downlink control message to the user terminal, wherein the downlink control message comprises the characteristic information of the updated synchronous signal block.

The third is to transmit a radio resource control message including a timer to the user terminal, and trigger the bandwidth part switching after a predetermined time of the timer has arrived. Wherein, when the default BWP to be switched is included in the radio resource control message, the bandwidth part may be switched to the default BWP; when the default BWP to be switched is not included in the radio resource control message, switching to the initial BWP may be performed. If the SSB included in the default BWP or the initial BWP is not the current reference SSB, the network side device configures the timer and, when the timer time is needed to be included in the configuration information, updates the reference SSB.

The network side equipment can send the reference synchronous signal block to the user terminal in any mode, the implementation mode is flexible, and the sending efficiency can be improved.

Optionally, the characteristic information of the reference synchronization signal block includes a center frequency point of the reference synchronization signal block and/or a number of the reference synchronization signal block.

The characteristic information of the reference synchronization signal block may be a center frequency point or a number of the reference synchronization signal block, and the user terminal may determine the reference synchronization signal block according to the center frequency point or the number of the reference synchronization signal block. This embodiment can be applied to any of the above embodiments, and flexibility of information can be improved.

For a further understanding of the present embodiments, the following description is provided by way of example in connection with the accompanying drawings.

For example, as shown in fig. 1a, the serving cell and the neighboring cell are the same carrier from the network perspective, i.e. the same frequency cell. Wherein, the serving cell and the neighbor cell are respectively configured with 2 SSB in the frequency domain.

The network side equipment sends measurement configuration information to the user terminal, wherein the measurement configuration information comprises a center frequency point of the SSB1 and a center frequency point of the SSB2, and the two frequency points are identified to belong to the same-frequency cell. The network side equipment sends a center frequency point of the reference SSB to the user terminal, wherein the frequency point is a center frequency point of the SSB 1.

The BWP activated by the ue is BWP including SSB1, and since the center frequency points of the reference SSB and SSB1 are the same, the ue determines that the measurement of the neighboring cell is the same-frequency measurement type requiring no measurement interval, and thus the ue measures the neighboring cell according to the same-frequency measurement type requiring no measurement interval.

And the measurement type is determined according to the reference SSB of the initial configuration, so that the waste of network resources can be reduced, and the system overhead is saved.

For example, as shown in fig. 1b, the serving cell and the neighboring cell are the same carrier from the network perspective, i.e. the same frequency cell. Wherein, the serving cell and the neighbor cell are respectively configured with 2 SSB in the frequency domain.

The user terminal activates BWP2 and updates the center frequency point of the reference SSB to the center frequency point of SSB 2.

Because the BWP activated by the user terminal includes SSB2, the center frequency points of the reference SSB and the SSB2 are the same, and the user terminal determines that the measurement mode of the neighboring cell is the same-frequency measurement without the measurement interval, so the user terminal measures the neighboring cell according to the type of the same-frequency measurement without the measurement interval.

And the measurement type is determined according to the updated reference SSB, so that the measurement mode is optimized, the waste of network resources can be reduced, and the system overhead is saved.

As shown in fig. 1d, the serving cell and the neighboring cell are the same carrier from the network perspective, i.e. the same frequency cell. Wherein 2 SSBs are configured on the service cell frequency domain, and 1 SSB is configured on the neighbor cell frequency domain.

The network side equipment sends measurement configuration information to the user terminal, wherein the measurement configuration information comprises a center frequency point of the SSB 1. The network side equipment sends a center frequency point of the reference SSB, namely a center frequency point of the SSB1, to the user terminal.

The user terminal activates BWP2 and the network updates the center frequency point of the reference SSB, i.e., the center frequency point of SSB 2. Because the BWP2 activated by the user terminal contains the SSB2, the positions of the center frequency points of the reference SSB and the SSB1 of the neighboring cell are different, the user terminal determines that the measurement mode of the neighboring cell is the same-frequency measurement requiring the measurement interval, and the user measures the neighboring cell according to the measurement type of the same-frequency measurement requiring the measurement interval.

In the embodiment of the invention, the network side equipment sends the current reference SSB to the user terminal, and the user terminal determines the measurement type based on the reference SSB, so that the waste of network resources is reduced.

Referring to fig. 3, fig. 3 is a schematic flow chart of a frequency point measurement method according to an embodiment of the present invention. As shown in fig. 3, a frequency point measurement method is applied to a network side device, and includes the following steps:

step 301, transmitting at least one of the following information for frequency point measurement to a user terminal: characteristic information of the current reference synchronous signal block; and the center frequency point of the synchronous signal block of the service cell where the user terminal is located. When the at least one piece of information comprises the center frequency point of the synchronization signal block of the service cell where the user terminal is located, the center frequency point of the synchronization signal block of the service cell where the user terminal is located is sent to the user terminal by sending second measurement configuration information to the user terminal, wherein the second measurement configuration information comprises the center frequency point of the synchronization signal block of the service cell where the user terminal is located.

In this embodiment, the network side device sends second measurement configuration information to the ue, where the second measurement configuration information includes center frequency points of all synchronization signal blocks of the serving cell where the ue is located. In addition, the second measurement configuration information may further include a frequency point to be measured. The terminal device may determine the measurement type based on the frequency point to be measured and the center frequency point of the SSB of the serving cell where the user terminal is located.

Optionally, the second measurement configuration information further includes a common-frequency measurement frequency point and an inter-frequency measurement frequency point of the cell to be measured.

In this embodiment, the second measurement configuration information includes a measurement frequency point of the same-frequency cell and a frequency point to be measured of the different-frequency cell, where the frequency point to be measured is a center frequency point of the SSB. The network side equipment respectively sends the frequency point to be measured of the same-frequency cell and the frequency point to be measured of the different-frequency cell to the user terminal, and the user terminal can optimize measurement and improve measurement efficiency based on the cell of the frequency point to be measured. The specific optimization mode can be seen from measurement of the to-be-measured frequency point of the same-frequency cell and the to-be-measured frequency point of the different-frequency cell at the user terminal side.

Optionally, the second measurement configuration information further includes a measurement interval parameter.

In this embodiment, the second measurement configuration information may further include measurement interval parameters, for example, a period of the measurement interval, a length of the measurement interval, a position of the measurement interval, and the like. In performing the inter-frequency measurement or the same-frequency measurement including the measurement interval, the measurement may be performed within the measurement interval according to the measurement interval parameter. The embodiment can improve the information transmission efficiency.

For a further understanding of the present embodiments, the following is illustrative in connection with specific embodiments.

Fourth, there are 2 SSBs on the serving cell frequency domain and 1 SSB on the co-frequency neighbor cell frequency domain. The network side equipment sends measurement configuration information to the user terminal, wherein the measurement configuration information comprises the center frequency points of 2 SSBs of the service cell, the center frequency points of 1 SSB of the same-frequency cell to be measured and measurement interval parameters.

As shown in fig. 1c, if the BWP activated by the ue includes SSB1, the ue determines that the measurement type of the neighboring cell is the same-frequency measurement without the measurement interval, so that the ue measures the neighboring cell according to the same-frequency measurement type without the measurement interval, the original measurement interval is invalidated, and the ue can perform data transmission in the original measurement interval.

As shown in fig. 1e, if the user activated BWP includes SSB2, the user terminal determines that the measurement of the neighbor cell is the same-frequency measurement requiring the measurement interval, and thus, the user terminal stops data transmission and reception to the serving cell within the measurement interval.

According to the frequency point measuring method, the network side equipment sends the center frequency point of the SSB of the service cell where the user terminal is located to the user terminal, so that the user terminal determines the measuring type according to the frequency point to be measured and the center frequency point of the service cell, and resource waste is reduced.

Referring to fig. 4, fig. 4 is a flow chart of another frequency point measurement method according to an embodiment of the present invention. As shown in fig. 4, a frequency point measurement method is applied to a user terminal, and includes the following steps:

step 401, obtaining information for frequency point measurement sent by network side equipment; wherein the information for frequency point measurement includes at least one of the following information: characteristic information of the current reference synchronous signal block; and the center frequency point of the synchronous signal block of the service cell where the user terminal is located.

The information for frequency point measurement may be characteristic information of the current reference synchronization signal block, where the characteristic information includes a characteristic of the reference synchronization signal block, for example, a number of the reference SSB or a center frequency point, and the current reference SSB of the serving cell may be determined according to the characteristic information. The user terminal can determine the measurement type of the frequency point to be measured according to the current reference SSB.

The user terminal may specifically obtain the current reference SSB by receiving measurement configuration information sent by the network side device, or may directly receive the current reference SSB sent by the network side device, which is not limited in this embodiment.

The implementation of this step may refer to the operation performed by the user terminal in step 101, which is not described herein.

Optionally, when the at least one piece of information includes characteristic information of a current reference synchronization signal block, the current reference synchronization signal block includes a reference synchronization signal block initially configured for the user terminal and/or an updated reference synchronization signal block when a bandwidth portion of the user terminal is switched.

The embodiment can be specifically described with reference to the corresponding description in the network side device, and achieve the same beneficial effects, which are not described herein again.

Optionally, when the current reference synchronization signal block includes a reference synchronization signal block initially configured for the user terminal, the feature information of the current reference synchronization signal block is obtained by receiving first measurement configuration information sent by the network side device, where the first measurement configuration information includes the reference synchronization signal block initially configured for the user terminal.

The embodiment can be specifically referred to the explanation related to the network side device, and can achieve the same beneficial effects, which are not described herein.

Optionally, when the current reference synchronization signal block includes a bandwidth part of the user terminal is switched, when the updated reference synchronization signal block is received, the characteristic information of the current reference synchronization signal block is obtained by receiving a radio resource control message sent by the network side device and indicating the bandwidth part is switched, where the radio resource control message includes the characteristic information of the updated reference synchronization signal block; or alternatively

Acquiring characteristic information of a current reference synchronous signal block by receiving a physical layer downlink control message sent by network side equipment and used for scheduling bandwidth partial switching, wherein the downlink control message comprises the characteristic information of the updated reference synchronous signal block; or alternatively

And acquiring the characteristic information of the current reference synchronous signal block by receiving a wireless resource control message comprising a timer sent by network side equipment, wherein the wireless resource control message is used for triggering the switching of the bandwidth part when the timing time of the timer is indicated, and the wireless resource control message comprises the characteristic information of the updated reference synchronous signal block.

Optionally, after the step of obtaining the information for frequency point measurement sent by the network side device, the method further includes: judging the measurement type of the frequency point to be measured according to the information for measuring the frequency point, wherein the measurement type comprises inter-frequency measurement, same-frequency measurement requiring measurement intervals and same-frequency measurement not requiring measurement intervals; and measuring the frequency points to be measured according to the measurement type.

In this embodiment, the user terminal determines a measurement type of the frequency point to be measured according to the received information for frequency point measurement. The measurement type determined according to the information for frequency point measurement can optimize the measurement mode, so that the resource waste can be reduced.

Optionally, when the at least one piece of information includes characteristic information of a current reference synchronization signal block, the step of determining a measurement type of a frequency point to be measured according to the information for frequency point measurement includes:

if the center frequency point of the synchronous signal block contained in the currently activated bandwidth part is the same as the position of the frequency point to be measured, the measurement type of the frequency point to be measured is the same-frequency measurement without the measurement interval;

if the center frequency point of the synchronous signal block contained in the currently activated bandwidth part is different from the position of the frequency point to be measured, the measurement type of the frequency point to be measured is the same-frequency measurement containing the measurement interval.

For example, as shown in fig. 1c, the activated BWP includes SSB1, and the position of the center frequency point of SSB1 is the same as the position of the frequency point to be measured, so that the same-frequency measurement without the measurement interval can be performed on the neighboring cell, the original measurement interval can be invalidated, and the resource waste can be reduced.

As shown in fig. 1e, the activated BWP includes SSB2, and if the position of the center frequency point of SSB2 is different from the position of the frequency point to be measured, the same-frequency measurement including the measurement interval is performed on the neighboring cell.

In this embodiment, different measurements are performed according to different measurement types, so that the resource utilization rate is improved, and the resource waste is reduced.

Optionally, when the at least one piece of information includes a center frequency point of a synchronization signal block of a serving cell where the ue is located, the step of determining, according to the information for frequency point measurement, a measurement type of a frequency point to be measured includes:

if the center frequency point of the synchronous signal block in the currently activated bandwidth part is the same as the frequency point to be measured, the measurement type of the frequency point to be measured is same-frequency measurement without a measurement interval;

if the currently activated bandwidth part does not comprise the synchronous signal block with the same central frequency point as the frequency point to be measured, the measurement type of the frequency point to be measured is the same-frequency measurement comprising a measurement interval;

if the center frequency point of all the synchronous signal blocks on the frequency domain of the service cell where the user terminal is located and the frequency point to be measured do not have the same frequency point, the measurement type is different frequency measurement.

The currently activated bandwidth portion does not include a synchronization signal block with the same center frequency point as the frequency point to be measured, and may include two cases: one is that the currently activated bandwidth part comprises a central frequency point which is different from the frequency point to be measured; another is that the currently active bandwidth portion does not include a center frequency bin.

Optionally, the step of measuring the frequency point to be measured according to the measurement type includes:

if the measurement type is the same-frequency measurement comprising the measurement interval, carrying out same-frequency measurement on the frequency point to be measured in the measurement interval according to the period of the measurement interval;

if the measurement type is the same-frequency measurement without the measurement interval, continuously measuring the frequency point to be measured;

and if the measurement type is inter-frequency measurement, performing inter-frequency measurement on the frequency point to be measured in the measurement interval according to the measurement interval period.

In this embodiment, if the measurement type is the same-frequency measurement including the measurement interval, the measurement interval is valid, and the ue cannot perform uplink transmission and downlink reception to the serving cell in the measurement interval.

If the measurement type is the same-frequency measurement without the measurement interval, the measurement interval is invalid, and the user terminal can perform uplink transmission and downlink reception on the serving cell in the original measurement interval, so that the resource waste can be reduced.

If the frequency points in the measurement configuration simultaneously comprise the measurement frequency points of the same-frequency SSB and the measurement frequency points of the different-frequency SSB, the user terminal periodically performs different-frequency measurement in the measurement interval and performs the same-frequency measurement comprising the measurement interval in the measurement interval.

According to the method and the device, the frequency points to be measured are measured according to the measurement types, so that resources can be optimized, and resource waste is reduced.

Optionally, when the at least one piece of information includes a center frequency point of a synchronization signal block of a serving cell where the user terminal is located, the center frequency point of the synchronization signal block of the serving cell where the user terminal is located is obtained by receiving second measurement configuration information, where the second measurement configuration information includes the center frequency point of the synchronization signal block of the serving cell where the user terminal is located.

In this embodiment, the ue receives second measurement configuration information sent by the network side device, where the second measurement configuration information may include center frequency points of all synchronization signal blocks of the serving cell where the ue is located, and the second measurement configuration information may also include a frequency point to be measured, where the ue may determine a measurement type of the frequency point to be measured according to the frequency point to be measured and the center frequency point of the synchronization signal block of the serving cell, so as to reduce resource waste.

The explanation of this embodiment may refer to the corresponding description in the network side device, and achieve the same beneficial effects, which are not described herein again.
