The third generation is the goal of people on speed, delay, high-speed mobility, energy efficiency and diversity and complexity of services in future lifePartner program (3) ^rd Generation Partnership Project,3 GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), low-Latency high-reliability Communication (URLLC), and massive Machine Type Communication (mMTC).

On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

In early NR deployment, complete NR coverage is difficult to obtain, so typical network coverage is wide-area LTE coverage and isolated island coverage pattern of NR. Moreover, a large amount of LTE is deployed below 6GHz, and the spectrum below 6GHz available for 5G is rare. NR must therefore be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading. Meanwhile, in order to protect the early LTE investment of a mobile operator, a work mode of tight cooperation (light interworking) between LTE and NR is provided.

NRs may also be deployed independently. NR will be deployed at high frequency in the future, and in order to improve coverage, in 5G, the requirement of coverage (coverage by space, space by time) is satisfied by introducing a beam scanning (beam scanning) mechanism, as shown in fig. 2. After the beam scanning is introduced, a synchronization Signal needs to be transmitted in each beam direction, and a 5G synchronization Signal is given in the form of a synchronization Signal block (SS/PBCH block, SSB) and includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSs), and a Physical Broadcast Channel (PBCH), as shown in fig. 3. The synchronization signal of 5G appears periodically in the time domain in the form of a burst set of synchronization signals (SS burst set), as shown in fig. 4.

The number of beams actually transmitted in each cell is determined by network side configuration, but the frequency point where the cell is located determines the maximum number of beams that can be configured, as shown in table 1 below.

Frequency range	L (maximum beam number)
		upto 3(2.4)GHz	4
3(2.4)GHz-6GHz	8
		6GHz-52.6GHz	64

TABLE 1

In Radio Resource Management (RRM) measurement, the measurement Signal may be an SSB measurement, that is, an SSS Signal in the SSB or a Demodulation Reference Signal (DMRS) Signal of a PBCH is measured to obtain a beam measurement result and a cell measurement result. In addition, the UE in a Radio Resource Control (RRC) connected state may also configure a Channel state indication Reference Signal (CSI-RS) as a Reference Signal for cell measurement.

For SSB-based measurements, the actual transmission location of the SSB may be different for each cell, as may the SS burst set period. Therefore, in order to save energy for the UE in the measurement process, the network side configures an SSB Measurement Timing Configuration (SMTC) for the UE, and the UE only needs to perform measurement in an SMTC window, as shown in fig. 5.

Since the actual transmission SSBs of each cell may have different locations, in order to enable the UE to find the actual transmission SSBs as soon as possible, the network side further configures the UE with the actual transmission SSBs measured by the UE, for example, a union of the actual transmission SSBs of all measured cells, as shown in table 2 below:

TABLE 2

For idle (idle) state, measurement configuration for inactive (inactive) state comes from network system broadcast configuration. These configuration information are configured with a cell as a granularity (per cell), for example, a list of measured pilot frequency points, etc., as shown in table 3 below:

TABLE 3

The measurement configuration for the connection state is configured by dedicated signaling, which is also configured by per cell.

The 5G communication technology has the characteristics of large bandwidth, high peak rate and low time delay, for example, 5G can transmit at the rate of several Gbps or several tens of Gbps on the bandwidth of hundreds of MHz and even several GHz. Therefore, the 5G technology can support real-time high-definition video live broadcast, high-definition film downloading, AR, VR and other services, and is expected to bring very good user experience, but is very power-consuming at the same time. How to consider the power saving of the 5G terminal is an issue to be solved. The current measurement saves the motor system:

RRM measurement power saving mechanism in RRC idle state

The terminal needs to perform intra-frequency or inter-frequency measurement in the RRC idle state in order to support mobility operation, such as performing cell reselection, based on the measurement result.

The terminal needs to continuously perform the intra-frequency or inter-frequency measurement RRM measurement in the RRC connected state based on the configuration of the network to support the mobility operation, such as handover or the like.

In order to save power for the terminal in the measurement process, for the RRC idle state, the following measurement rules are currently supported:

for intra-frequency measurements, if the measurement results of the serving cell satisfy: srxlev > SIntraSearchP and Squal > SIntraSearchQ, and the terminal can choose not to perform same-frequency measurement; otherwise, the terminal needs to perform the same-frequency measurement.

For inter-frequency measurements and inter-system (inter-RAT) measurements, the following rules are applied:

for the NR frequency point or inter-RAT frequency band with higher reselection priority than the current NR frequency point, the terminal needs to perform inter-frequency or inter-system measurement;

-for NR frequency points or inter-RAT frequency points having a lower or same reselection priority than the current NR frequency point; ,

-if the serving cell measurement result satisfies Srxlev > snonIntraSearchP and Squal > snonIntraSearchQ terminal I may choose not to perform inter-frequency or inter-system measurements;

otherwise, the terminal performs inter-frequency or inter-system measurements.

RRM measurement power saving mechanism in RRC connected state

RRM measurement can be carried out on the terminals in the RRC connection state based on an S-measure criterion, and the S-measure criterion can be based on SS/PBCH measurement and CSI-RS measurement. Namely: if the RSRP measured by the terminal based on SS/PBCH block or CSI-RS is larger than the corresponding threshold ssb-RSRP or CSI-RSRP, the terminal only needs to execute the measurement of the serving cell and does not execute the measurement outside the serving cell; otherwise, the terminal performs the RRM measurement according to the configuration of the MO.

In the above-described technique, the UE is configured for the current serving cell regardless of whether idle, inactive state measurement configuration or connected state measurement configuration is performed according to network side configuration. In cell deployment, a frequency priority is assigned to a frequency point of each cell, and meanwhile, a UE in idle and inactive states can continuously search for a frequency layer with a high priority, and meanwhile, the UE does not know which frequency layers with high priorities exist around, so that blind searching for the frequency layer with the high priority also wastes power of the UE.

In NR, due to the introduction of beams, although the UE moves within the current cell, the UE has moved under different beam coverage, and since the UE is under different beams of the same cell, the location of the UE can be accurately located to some extent. For example, the UE is under a certain beam, and the network deployment and topology structure to which the UE faces are different, as shown in fig. 6. However, the above power saving mechanism does not fully consider the UE location information; there is therefore some further room for optimization. The application provides a measurement configuration method for RRM measurement, aiming at further reducing the measurement power consumption of a terminal.

Fig. 7 is a schematic flowchart of a measurement configuration method according to an embodiment of the present application, and as shown in fig. 7, the measurement configuration method includes the following steps:

step 701: the terminal acquires first configuration information, wherein the first configuration information comprises at least one measurement configuration, and each measurement configuration is associated with at least one beam.

In the embodiment of the application, the terminal is any device capable of communicating with a network, such as a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted terminal, and a wearable device.

In this embodiment of the present application, the terminal acquires the first configuration information from a network side, and specifically, the terminal may acquire the first configuration information in the following manner:

the method I comprises the following steps: and under the condition that the terminal is in an idle state or an inactive state, the terminal acquires the first configuration information from a system broadcast message or a special signaling.

Specifically, for UEs in idle and inactive states, in a cell supporting beam surfing, the network side configures measurement configuration of per beam or per beam group through a system broadcast message. Here, the measurement configuration of per beam means that one beam is associated with each measurement configuration, and the measurement configuration of per beam group means that a plurality of beams (i.e., a group of beams) are associated with each measurement configuration. Here, the UE performs measurement on the common beam configured in the system broadcast message.

Here, the measurement configuration includes at least one of: list of measured frequencies, actual transmission location of SSB, SMTC, frequency priority. It should be noted that the actual transmission location of the SSB is also SSB-ToMeasure.

The second method comprises the following steps: and under the condition that the terminal is in an activated state, the terminal acquires the first configuration information from a special signaling.

Specifically, for a connected state UE, in a cell supporting beam roaming, the network side configures measurement configuration of a per beam or a per beam group through dedicated signaling. Here, since the UE is in a connected state, the UE can measure the proprietary beam; or, the UE measures the public beam configured in the system broadcast message.

Here, the measurement configuration includes at least one of: a list of measured frequencies, an actual transmission location of the SSB, SMTC, a measurement white list, a measurement black list. It should be noted that the actual transmission location of the SSB is also SSB-ToMeasure. The measurement white list provides content that needs to be measured and the measurement black list provides content that does not need to be measured.

Step 702: and the terminal determines at least one target beam meeting a first condition according to the beam measurement result of the target cell.

In this embodiment of the present application, the terminal determines, according to a beam measurement result of a target cell, at least one target beam that meets a first condition, which may be implemented by, but is not limited to:

1) The terminal measures each beam of the target cell to obtain Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) of each beam; and the terminal selects the first N wave beams with the maximum value of the RSRP and/or the RSRQ as target wave beams based on the RSRP and/or the RSRQ of each wave beam, wherein N is more than or equal to 1.

For example: the UE measures all beams of the cell to obtain the measurement result of each beam: and sequencing the values of the RSRP and/or the RSRQ from large to small, wherein the beam of Top1 is a target beam.

For example: the UE measures all beams of the cell to obtain the measurement result of each beam: and the RSRP and/or the RSRQ are used for sequencing the values of the RSRP and/or the RSRQ from large to small, and N beams from Top1 to Top N are target beams.

2) The terminal measures each wave beam of the target cell to obtain Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) of each wave beam; and the terminal selects M wave beams with the value of RSRP and/or RSRQ more than or equal to a first threshold value as target wave beams based on the RSRP and/or RSRQ of each wave beam, wherein M is more than or equal to 1.

For example: the UE measures all beams of the cell to obtain the measurement result of each beam: and selecting all beams with the value of RSRP and/or RSRQ larger than or equal to a first threshold value, wherein the number of all beams larger than or equal to the first threshold value is assumed to be M.

3) The terminal measures each wave beam of the target cell to obtain the RSRP and/or the RSRQ of each wave beam; and the terminal selects a maximum number P of beams with the value of RSRP and/or RSRQ being more than or equal to a first threshold value as target beams based on the RSRP and/or RSRQ of each beam, wherein P is more than or equal to 1.

For example: the UE measures all beams of the cell to obtain the measurement result of each beam: and selecting partial beams with the value of RSRP and/or RSRQ being larger than or equal to a first threshold value, wherein the number of the partial beams with the value of RSRP and/or RSRQ being larger than or equal to the first threshold value is assumed to be P. The first P beams may be selected to be greater than or equal to a first threshold.

Step 703: the terminal determines a valid measurement configuration from the at least one measurement configuration based on the at least one target beam, and performs a measurement operation based on the valid measurement configuration.

In the embodiment of the present application, the effective measurement configuration may be determined by the following conditions:

the first condition is as follows: the number of the target beams is one

1) For a measurement configuration associated with a beam, if the beam associated with the measurement configuration is the target beam, determining that the measurement configuration is a valid measurement configuration; wherein the terminal takes the valid measurement configuration as a measurement configuration for performing a measurement operation.

For example: for per beam measurement configuration, 1 target beam is determined from the beam measurement: beam1, if beam1 is associated with measurement configuration 1, then take measurement configuration 1 as the measurement configuration finally used by the UE.

2) For a measurement configuration associated with a plurality of beams, determining that the measurement configuration is a valid measurement configuration if the plurality of beams associated with the measurement configuration include the target beam; wherein if there are a plurality of valid measurement configurations in the first configuration information: and the terminal takes the plurality of effective measurement configurations as the measurement configurations used for executing the measurement operation.

For example: for the measurement configuration of perbeamgroup, 1 target beam is determined according to the beam measurement result: beam1, if beam1 and beam2 are associated with measurement configuration 2, and beam1, beam3 and beam4 are associated with measurement configuration 3, then measurement configuration 2 and measurement configuration 3 are both used as the measurement configuration for the final UE.

Case two: the number of the target beams is multiple

1) For a measurement configuration associated with a beam, determining that the measurement configuration is a valid measurement configuration if the beam associated with the measurement configuration is one of the first set of beams; wherein if there are a plurality of valid measurement configurations in the first configuration information: and the terminal takes the plurality of effective measurement configurations as the measurement configurations used for executing the measurement operation.

For example: for per beam measurement configuration, 2 target beams are determined from the beam measurements: beam1, beam2, if beam1 is associated with measurement configuration 1, and beam2 is associated with measurement configuration 2, then measurement configuration 1 and measurement configuration 2 are both used as the measurement configuration finally used by the UE.

2) The plurality of target beams form a first set of beams; for a measurement configuration associated with a plurality of beams, the plurality of beams associated with the measurement configuration form a second set of beams, wherein:

determining that the measurement configuration is a valid measurement configuration if the second set of beams includes the first set of beams; or,

determining that the measurement configuration is a valid measurement configuration if the first set of beams includes the second set of beams; or,

determining that the measurement configuration is a valid measurement configuration if there is an intersection of the first set of beams with the second set of beams.

Here, if there are a plurality of valid measurement configurations in the first configuration information:

the terminal takes the plurality of effective measurement configurations as measurement configurations used for executing measurement operation; or,

the terminal selects at least one target measurement configuration satisfying a second condition from the plurality of valid measurement configurations as a measurement configuration used for performing a measurement operation.

Further, the meeting of the second condition means:

measuring that a number of intersections of the second set of beams associated with the configuration with the first set of beams is maximum; or,

the number of intersections of the first set of beams with the second set of beams associated with the measurement configuration is greater than or equal to a second threshold value.

For example: for the measurement configuration of per beam group, the beam group associated with the measurement configuration is called a beam set a, and a plurality of beams are determined according to the beam measurement result, and the plurality of beams are called a beam set B, then:

(1) If the beam set A is larger than or equal to the beam set B, determining all the beam sets A containing the beam set B, and taking the union of the measurement configurations corresponding to all the beam sets A as the measurement configuration used by the UE last time; as in case a and case b of fig. 8.

(2) If the beam set A is smaller than the beam set B, determining all beam sets A containing at least one beam in the beam set B, and taking the union of the measurement configurations corresponding to all the beam sets A as the measurement configuration used by the UE last time, or determining the beam set A with the maximum intersection with the beam set B and taking the union of the measurement configurations corresponding to the beam set A as the measurement configuration used by the UE last time; as in case c of fig. 8.

(3) If the beam set A and the beam set B do not belong to the relationship and have an intersection, determining all beam sets A containing at least one beam in the beam set B, and taking the union of the measurement configurations corresponding to all the beam sets A as the measurement configuration used by the UE last, or determining the beam set A with the maximum intersection with the beam set B and taking the union of the measurement configurations corresponding to the beam set A as the measurement configuration used by the UE last; as in case d of fig. 8.

In the above solution, the first configuration information includes a measurement configuration list, and each measurement configuration in the measurement configuration list configures one SSB index or a group of SSB indexes to be associated with the measurement configuration. As shown in the following tables 4 and 5,

TABLE 4

TABLE 5

In this embodiment of the present application, each measurement configuration in the first configuration information is associated with an actually transmitted beam in the following manner: each measurement configuration in the first configuration information has a one-to-one correspondence between a sequence number in the first configuration information and a sequence number of an actually transmitted beam, as shown in table 6 below, where each mterfrequierfreqlist forssblist is a one-to-one correspondence from small to large of an actual transmission SSB index indicated in SIB1 corresponding to each mterfrequierfreqlist in the list.

TABLE 6

In addition, in the embodiment of the application, for the SSB index or SSB index group associated with the SMTC and/or SSB-ToMeasure in the measurement configuration, what SMTC and/or SSB-ToMeasure configuration is to be adopted is determined according to the beam measurement result measured by the UE. Not to mention an example here, the configuration of SSBs associated with a frequency only, SMTC, and/or SSB-to-measure are configured in per frequency. The SMTC and the SSB-ToMeasure can be independently associated with the SSB or can be associated with the SSB together. If the SMTC and SSB-ToMeasure are independently configured, they are configured as shown in Table 8 below. If configured together, are configured as in Table 7 below.

TABLE 7

TABLE 8

In the embodiment of the present application, the SMTC, SSB-to measure, the measurement black list (blackCellsToAddModList), and the measurement white list (whiteccellstoaddmodlist) may all be associated with one SSB or a group of SSBs in the measurement configuration, and are configured as shown in table 9 below.

TABLE 9

On the other hand, the measurement object list may be associated with one SSB or one SSB group, as shown in table 10 below:

TABLE 10

In the embodiment of the application, for a terminal in idle and inactive states, the terminal determines whether a frequency layer with higher frequency priority exists or not based on the effective measurement configuration, and if the frequency layer with higher priority does not exist, the terminal stops starting and searching the measurement of the frequency layer with high priority until the cell reselection occurs and then starts the measurement of the frequency layer with high priority; or the terminal receives first indication information configured by a network side, wherein the first indication information is used for indicating whether to start high-priority frequency layer search, and if the first indication information indicates that the high-priority frequency layer search is not started, the terminal stops starting measurement of searching the high-priority frequency layer until cell reselection occurs and then starts measurement of the high-priority frequency layer.
