Figure 1 illustrates a network environment 100 in accordance with some embodiments. The network environment 100 may include a UE 104 and a base station 108. The base station 108 may provide a serving cell (SC) 110 through which the UE 104 may communicate with the base station 108. In some embodiments, the base station 108 is a next-generation node B (gNB) that provides one or more 3GPP New Radio (NR) cells. In other embodiments, the base station 108 is an evolved node B (eNB) that provides one or more Long Term Evolution (LTE) cells. The air interface over which the UE 104 and base station 108 communicate may be compatible with 3GPP technical specifications, such as those that define Fifth Generation (5G) NR or later system standards.

The network environment 100 may further include one or more neighbor base stations that provide non-serving cells. For example, the network environment may include base station 116 that provides non-serving cell (NSC) 112. The base station 116 may use the same radio access technology as the base station 108 or a different radio access technology.

To adapt to changes in a radio environment and relative positioning between the UE 104 and the base stations, the UE 104 may be configured to perform a variety of measurements on reference signals transmitted in both the serving cell 110 and the non-serving cell 112. The base station 108 may transmit measurement configurations to provide the UE 104 with information to perform the reference signal measurements. Upon performing the measurements, the UE 104 may provide a measurement report to the base station 108. The base station 108 may perform various radio resource management (RRM) operations based on the measurement report.

The measurement configurations may instruct the UE 104 to perform measurements based on reference signals that include, for example, channel-state information –reference signals (CSI-RSs) and synchronization signal and physical broadcast channel blocks (SSBs) . The measurements may be beam-level or cell-level.

The measurement configurations may be transmitted to the UE 104 while the UE 104 is in a radio resource control (RRC) -connected mode by dedicated signaling, such as RRC signaling (for example, an RRC reconfiguration message or RRC resume message) .

In some embodiments, a measurement configuration may include (directly or by reference) a measurement identity, a measurement object, and a reporting configuration. The measurement identity may link a reporting configuration to a measurement object. The measurement identity may include a first pointer toward a reporting configuration and a second pointer toward a measurement object that provides information about the SSB resources that are to be measured. The UE 104 may provide measurement results within an RRC message (for example, an RRC measurement report) that includes the measurement ID as a reference.

The reporting configuration may provide a periodic, event-triggered, or cell global identity (CGI) configuration. The reporting configuration may include parameters, such as report amount, reporting interval, and, if the configuration is an event-triggered configuration, a measurement reporting event. The report amount and reporting interval may be abstract syntax notation one (ASN. 1) fields in a report configuration information element (IE) . The report amount may describe how many times a measurement report is to be transmitted based on a triggering event. The triggering event may be a period elapsing (for a periodic configuration) or a triggering condition of a measurement reporting event being satisfied (for an event-triggered configuration) . The reporting interval may provide a time between successive transmissions of the measurement report. The reporting configuration may further describe the reference signal type (for example, SSB) that may be used for the periodic or event-triggered configurations.

The SSBs may be used for reference signal receive power (RSRP) measurements at Layer 1 (L1) or Layer 3 (L3) . The L1 measurements may be used to monitor and respond to radio channel conditions on a shorter time frame as compared with L3 measurements. The L1 measurements may be used to, for example, perform beam management procedures, while the L3 measurements may be used to, for example, perform handover procedures.

In some embodiments, consistent with Release 17 3GPP TSs definition of further enhanced multiple-input, multiple-output (FeMIMO) in 3GPP TS 38.214 v17.2.0 (2022-06-23) and TS 38.331 v17.1.0 (2022-07-19) , the UE 104 may be configured for L1-reference signal received power (RSRP) measurements on the NSC 112. The NSC 112 may have a different physical cell identity (PCI) than the PCI of the SC 110. In some embodiments, the NSC 112 may be referred to as a cell with different (or additional) PCI (CDP) . The L1-RSRP measurements for the NSC 112 may provide the basis for inter-cell beam management. The serving base station 108 may use inter-cell beam management to instruct the UE 104 to switch from a beam associated with the SC 110 to a beam associated with the NSC 112 for receiving a physical downlink shared channel (PDSCH) or physical downlink control channel (PDCCH) . This may be done with a simple transmission configuration indication (TCI) state switch without having to do a complete handover, which relies on layer 3 (L3) measurements and takes more time. Performing this dynamic beam switch may often be done when the UE 104 is operating in the higher frequency ranges, for example, frequency range 2 (FR2) , from 24.25 GHz to 52.6 GHz, or above.

Performing L1-RSRP measurements on CDPs requires coordinated management of a number of measurement configurations. For example, SSB occasions from the serving cell 110 may overlap with SSB occasions from the NSC 112. Furthermore, the SSB occasions (from either SC 110 or NSC 112) may overlap with occasions from a measurement gap (MG) configuration (used for inter-frequency or inter-radio access technology (RAT) measurements) and occasions from SSB measurement timing configuration (SMTC) (used to define the measurement opportunities for performing the L3 measurements) .

Embodiments describe how to determine sharing factors that may be used in FR2 and above to share measurement occasions between different measurements. The sharing factors may be determined for a variety of cases including, when the SMTC and MG fully or partially overlap with one another and both overlap with SSBs from the SC 110 or NSC 112, and the SSBs from the SC 110 or NSC 112 fully or partially overlap with one another. In another case, the SMTC and MG do not overlap, but overlap with SSBs from the SC 110 or NSC/CDP 112, and the SSBs from the SC 110 or NSC/CDP 112 fully or partially overlap with one another.

The UE 104 may use the sharing factor to determine which measurement occasions to use for a particular measurement. The network may use the sharing factor to determine an L1-RSRP measurement period. 3GPP TS 38.133 v17.6.0 (2022-06-30) defines the L1 measurement period, T _{L1-RSRP_Measurement_Period_SSB}, based on sharing factor (P) . The L1 measurement period is a period in which a physical layer of the UE 104 is to determine L1-RSRP measurements with a sufficient accuracy. If the UE 104 does not report configured L1-RSRP measurements over the L1 measurement period, the base station 108 may determine there is a beam or radio-link failure and attempt to perform a radio resource management (RRM) operation such as configuring a new beam or cell.

In FR2, the L1 measurement period for the SC 110 may be determined as follows. Unless described elsewhere herein, the parameters used to calculate the L1 measurement period for the SC 110 may be similar to like-named parameters in clause 9.5.4.1 of 3GPP TS 38.133.

If the UE 104 is not operating in accordance with a discontinuous reception (DRX) configuration, the L1 measurement period may be equal to max (T _report, ceil (M *P *N) *T _SSB) . T _report may be a configured periodicity for reporting, T _SSB may be the periodicity of an SSB index configured for L1-RSRP measurements of the SC 110, M is equal to one if a time restriction for channel measurement parameter is configured or is equal to three otherwise, and N is eight.

If the UE 104 is operating in accordance with a DRX configuration not more than 320 milliseconds, the L1 measurement period may be equal to max (T _report, ceil (1.5 *M *P *N) *max (T _DRX, T _SSB) . T _DRX is a DRX cycle length and the rest of the parameters may be similar to those described above and in clause 9.5.4.1 of TS 38.133.

If the UE 104 is operating in accordance with a DRX configuration more than 320 milliseconds, the L1 measurement period may be equal to ceil (1.5 *M *P *N) *T _DRX. The parameters may be similar to that described above and in clause 9.5.4.1 of TS 38.133.

In FR2, the L1 measurement period for the NSC 112 may be determined as follows. Unless described elsewhere herein, the parameters used to calculate the L1 measurement period for the NSC 112 may be similar to like-named parameters in clause 9.13.4 of 3GPP TS 38.133.

If the UE 104 is not operating in accordance with a discontinuous reception (DRX) configuration, the L1 measurement period may be equal to max (T _report, ceil (M *P *N) *T _SSB, CDP) . T _report may be a configured periodicity for reporting, T _SSB, CDP may be the periodicity of an SSB index configured for the inter-cell L1-RSRP measurements of the NSC/CDP 112, M is equal to one if a time restriction for channel measurement parameter is configured or is equal to three otherwise, and N is eight.

If the UE 104 is operating in accordance with a DRX configuration not more than 320 milliseconds, the L1 measurement period may be equal to max (T _report, ceil (1.5 *M *P *N) *max (T _DRX, T _SSB, CDP) . T _DRX is a DRX cycle length.

If the UE 104 is operating in accordance with a DRX configuration more than 320 milliseconds, the L1 measurement period may be equal to ceil (1.5 *M *P *N) *T _DRX.

Embodiments of the present disclosure describe how to determine the sharing factor (P) , which may be used to determine the L1-RSRP measurement period for FR2 as described above, in a number of different scenarios.

In a first aspect of the disclosure, a periodicity relationship may be detected among at least two periodicities. The at least two periodicities may include periodicities associated with an SSB configuration of the SC 110 (referred to herein as T _SSB, SC) , an SSB configuration of the NSC 112 (referred to herein as T _SSB, CDP) , an MG configuration (referred to herein as MGRP) , or the SMTC (referred to herein as T _SMTC) . The periodicity relationship may be used as a basis to determine an intermediate sharing factor. An overlapping relationship may also be determined with respect to the SC SSB configuration and the SMTC or the MG configuration. A final sharing factor may then be determined based on the intermediate sharing factor and the overlapping relationship.

FIGs. 2 and 3 illustrate tables 200 and 300, respectively, for determining intermediate sharing factors based on periodicity relationships in accordance with some embodiments.

The table 200 may include an intermediate sharing factor P _SC for determining the sharing factor for the SC 110; and may include an intermediate sharing factor P _CDP for determining the sharing factor for the NSC 112.

In a first scenario, the periodicity relationship is defined by T _SSB, SC = T _SSB, CDP < T _SMTC. In this case, both the intermediate sharing factors P _SC and P _CDP may be set equal to two.

In a second scenario, the periodicity relationship is defined by T _SSB, CDP <T _SSB, SC = T _SMTC. In this case, both the intermediate sharing factors P _SC and P _CDP may be set equal to one.

In a third scenario, the periodicity relationship is defined by T _SSB, SC < T _SSB, CDP < (T _SMTC and MGRP) . The third scenario may also be associated with the condition in which the target SSB configuration (e.g., the SC SSB configuration or the NSC SSB configuration, depending on which measurements are to be performed) partial overlaps with both the SMTC and MG configurations. A first configuration may be said to partially overlap with a second configuration if some occasions of the first configuration occur at the same time as occasions of the second configuration, while other occasions of the first configuration occur at different times than occasions of the second configuration.

For the third scenario, P _SC may be set equal to:

and P _CDP may be set equal to 1.

In a first option of the third scenario, referred to as scenario 3a, the periodicity relationship is defined by T _SSB, SC < T _SSB, CDP < T _SMTC. The 3a scenario may also be associated with the condition in which the target SSB configuration partially overlaps with the SMTC and does not overlap with the MG configuration.

For the 3a scenario, P _SC may be set equal to:

and P _CDP may be set equal to 1.

In a second option of the third scenario, referred to as scenario 3b, the periodicity relationship is defined by T _SSB, SC < T _SSB, CDP < MGRP. The 3b scenario may also be associated with the condition in which the target SSB configuration partially overlaps with the MG configuration and does not overlap with the SMTC.

For the 3b scenario, P _SC may be set equal to:

and P _CDP may be set equal to 1.

In a fourth scenario, the periodicity relationship is defined by T _SSB, CDP < T _SSB, SC < (T _SMTC and MGRP) . The fourth scenario may also be associated with the condition in which the target SSB configuration partial overlaps with both the SMTC and MG configurations.

For the fourth scenario, P _SC may be set equal to 1 and P _CDP may be set equal to:

In a first option of the fourth scenario, referred to as scenario 4a, the periodicity relationship is defined by T _SSB, CDP < T _SSB, SC < T _SMTC. The 4a scenario may also be associated with the condition in which the target SSB configuration partially overlaps with the SMTC and does not overlap with the MG configuration.

For the 4a scenario, P _SC may be set equal to 1 and P _CDP may be set equal to:

In a second option of the fourth scenario, referred to as scenario 4b, the periodicity relationship is defined by T _SSB, CDP < T _SSB, SC < MGRP. The 4b scenario may also be associated with the condition in which the target SSB configuration partially overlaps with the MG configuration and does not overlap with the SMTC.

For the 4b scenario, P _SC may be set equal to 1 and P _CDP may be set equal to:

In a fifth scenario, the periodicity relationship is defined as T _SSB, CDP >= T _SMTC. In this scenario, no L1-RSRP requirement may be applied.

A sixth scenario may be associated with a condition in which SSB occasions of the SC and NSC fully overlap outside MG and SMTC occasions. In this case, both the intermediate sharing factors P _SC and P _CDP may be set equal to two.

In a seventh scenario, the periodicity relationship is defined as T _SSB, SC <T _SSB, CDP. The seventh scenario may also be associated with the condition in which SSB occasions of the SC SSB configuration and the NSC SSB configuration partially overlap one another and are outside the occasions of both the MG configuration and the SMTC.

In the seventh scenario, the P _SC may be set equal to

and the P _CDP may be set equal 1.

The intermediate sharing factor determined based on table 200 or 300 may be used to determine a final sharing factor as described below with respect to one of four cases.

In a first case, SSBs of a target SSB configuration may partially overlap with occasions of both the MG configuration and the SMTC, and the MG configuration may partially or fully overlap with the SMTC. In this case, the final sharing factor, P, may be provided by:

where P _ISF is the intermediate sharing factor (P _SC or P _CDP) as given by Tables 200 or 300 discussed above. T _SSB may be the periodicity associated with the target SSB configuration.

In a second case, SSBs of the target SSB configuration partially overlap with occasions of both the MG configuration and the SMTC, and the MG configuration does not overlap with the SMTC. In this case, the final sharing factor, P, may be provided by:

In a third case, SSBs of the target SSB configuration partially overlap with occasions of the MG configuration, but do not overlap with occasions of the SMTC. In this case, the final sharing factor, P, may be provided by:

In a fourth case, SSBs of the target SSB configuration partially overlap with occasions of the SMTC, but do not overlap with occasions of the MG configuration. In this case, the final sharing factor, P, may be provided by:

FIG. 4 illustrates example occasions 400 in accordance with some embodiments. The occasions 400 may include occasions from SC SSB configuration, an NSC SSB configuration, an MG configuration, and an SMTC. The occasions 400 represent an example of scenario 3 in which T _SSB, _SC < T _SSB, _CDP < (T _SMTC and MGRP) and the SSB configurations partially overlap with the MG configuration and the SMTC, and the MG configuration and SMTC are partially or fully overlapped.

The SC SSB configuration may configure SC SSB occasions with a 10-ms periodicity and an offset of zero. The NSC SSB configuration may configure NSC SSB occasions with a 20-ms periodicity and an offset of zero. The SMTC may configure occasions with a 40-ms periodicity and an offset of zero. The MG configuration may configure MG occasions with a 80-ms periodicity an offset of zero.

In this case, both the MG occasions and the SMTC occasions partially overlap with the SC SSB occasions. Therefore, the P _SC may need to consider periodicities from both the MG (for example, the MGRP) and the SMTC (for example, the T _SMTC) .

As the periodicity relationship of the occasions 400 corresponds to scenario 3 in FIG. 2, P _SC may be found by:

which reduces to 3/2. This intermediate sharing factor may be used with the formula from the first case discussed above in which the target SSB configuration partially overlaps with SMTC and MG and MG and SMTC are partially or fully overlapped. In particular, the P _SC may be used to determine the final sharing factor, P, by:

which reduces to 2.

A final sharing factor may mean that if a measurement needs x samples, the UE 104 may need P *x occasions in order to obtain those x samples. For example, with reference to FIG. 4, if the UE 104 needs four samples of the SC SSB, it may need 4 *2 SC SSB occasions. The four samples obtained from the eight occasions are show in FIG. 4 with the dotted fill in the occasions at 10 ms, 30 ms, 50 ms, and 70 ms.

The intermediate sharing factor for the NSC 112, P _CDP, may be set to one for scenario 3 as shown by the Table 200. Using the same formula for the final sharing factor:

which reduces to 2.

With reference to FIG. 4, if the UE 104 needs two samples of the NSC SSB, it may need 2 *2 NSC SSB occasions. The two samples obtained from the four occasions are show in FIG. 4 with the dotted fill in the occasions at 20 ms and 60 ms.

FIG. 5 illustrates example occasions 500 in accordance with some embodiments. The occasions 500 may include occasions from SC SSB configuration, an NSC SSB configuration, an MG configuration, and an SMTC. The occasions 500 represent an example in which the MG occasions do not overlap with the SMTC occasions or the NSC SSB occasions, but do partially overlap with the SC SSB occasions.

The SC SSB configuration may configure SC SSB occasions with a 10-ms periodicity and an offset of zero. The NSC SSB configuration may configure NSC SSB occasions with a 20-ms periodicity and an offset of zero. The SMTC may configure occasions with a 40-ms periodicity and an offset of zero. The MG configuration may configure MG occasions with a 10-ms offset and a 20-ms periodicity.

In this case, outside the SMTC occasions and MG occasions, the SC SSB occasions and the NSC SSB occasions are fully overlapped. This may correspond to scenario 6 of Table 300. Thus, the intermediate sharing factor for both the SC and the NSC is two, for example, P _SC = 2 and P _CDP = 2.

Since the SC SSB occasions overlap with both the MG occasions and the SMTC occasions, the intermediate sharing factors may be used with the formula from the second case discussed above in which the target SSB configuration partially overlaps with SMTC and MG, but the MG and SMTC do not overlap. In particular, the P _SC may be used to determine the final sharing factor, P, by:

which reduces to 8.

With reference to FIG. 5, if the UE 104 needs one sample of the SC SSB, it may need 8 *1 SC SSB occasions. The one sample obtained from the eight occasions is shown in FIG. 5 with the dotted fill in the SC SSB occasion at 20 ms.

Since the NSC SSB occasions only overlap with the SMTC occasions, the P _CDP may be used in the formula associated with the fourth case discussed above. In particular, the final sharing factor, P, may be determined by:

which reduces to 4.

With reference to FIG. 5, if the UE 104 needs one sample of the NSC SSB, it may need 1 *4 NSC SSB occasions. The one sample obtained from the four occasions is show in FIG. 5 with the dotted fill in the NSC SSB occasion at 60 ms.

In some embodiments, instead of determining an intermediate sharing factor and using the intermediate sharing factor to calculate the final sharing factor, the final sharing factor may be derived directly based on counting of the number of available occasions.

FIG. 6 illustrates a table 600 for directly determining a final sharing factor in accordance with some embodiments. The direct determination of the final sharing factor in table 600 may be based on one or more of the following four overlap numbers.

A first overlap number, SSB _SC1, is a number of SSB occasions of the SC 110 that overlap with SSB occasions of the NSC 112 but do not overlap with occasions of the MG configuration or SMTC within a time period equal to max (MGRP, T _SMTC) .

A second overlap number, SSB _CDP1, is a number of SSB occasions of the NSC 112 that overlap with SSB occasions of the SC 110 but do not overlap with occasions of the MG configuration or SMTC within a time period equal to max (MGRP, T _SMTC) .

A third overlap number, SSB _SC2, is a number of SSB occasions of the SC 110 that do not overlap with SSB occasions of the NSC 112, occasions of the MG configuration, or occasions of the SMTC within a time period equal to max (MGRP, T _SMTC) .

A third overlap number, SSB _CDP2, is a number of SSB occasions of the NSC 112 that do not overlap with SSB occasions of the SC 110, occasions of the MG configuration, or occasions of the SMTC within a time period equal to max (MGRP, T _SMTC) .

In a first scenario, the periodicity relationship is defined by T _SSB, SC = T _SSB, CDP < T _SMTC or MGRP. That is, both periodicities associated with the SC SSB configuration and the NSC SSB configuration are equal to one another, are less than the periodicity associated with SMTC, and are less than the periodicity associated with the MG configuration.

In the first scenario, the sharing factor, P, for the SC 110 may be given by:

and the sharing factor, P, for the NSC 112 may be given by:

In a second scenario, the periodicity relationship is defined by T _SSB, SC <T _SSB, CDP < T _SMTC or MGRP. That is, the periodicity associated with SC SSB configuration is less than the periodicity associated with the NSC SSB configuration and the periodicity associated with the NSC SSB configuration is less than the periodicity associated with SMTC and is also less than the periodicity associated with the MG configuration. The second scenario may also be associated with the condition in which all the SC SSB occasions collide with NCS SSB occasions, occasions of the MG configuration, or occasions of the SMTC.

Figure 11 illustrates an operation flow/algorithmic structure 1100 in accordance with some aspects. The operation flow/algorithmic structure 1100 may be performed or implemented by a UE, such as

UE

104 or 1400; or components thereof; for example, baseband processor 1404A.

The periodicity relationship may be among at least two periodicities that include a first periodicity associated with the SC SSB configuration, a second periodicity associated with the NSC SSB configuration, a third periodicity of an SSB measurement timing configuration (SMTC) , or a fourth periodicity of a measurement gap (MG) configuration. The periodicity relationship determined may be one of those referenced in any one of scenarios 1–7 of Tables 200 and 300.

The overlapping relationship may be with respect to a target SSB configuration and the SMTC or the MG configuration. The target SSB configuration may be the SC SSB configuration or the NSC SSB configuration.

The operation flow/algorithmic structure 1100 may further include, at 1112, determining an intermediate sharing factor. The intermediate sharing factor may be P _SC or P _CDP depending on whether the measurement to be performed is for an SC or NSC/CDP, respectively.

The intermediate sharing factor may be determined based on formulas associated with one of scenarios 1–7 of Tables 200 and 300. This may be based on the periodicity relationship determined at 1108. In some instances, the particular scenario may also be determined based on associated conditions as described above with respect to Tables 200 and 300.

With respect to scenarios 3–3b, the periodicity relationship may include SC SSB periodicity being less than the NSC SSB periodicity, and the NSC SSB periodicity being less than the SMTC periodicity or the MG periodicity. And the intermediate sharing factor may be one or based on a ratio of the SC SSB periodicity to the NSC SSB periodicity.

And the intermediate sharing factor may be one or based on a ratio of the NSC SSB periodicity to the SC SSB periodicity.

With respect to

scenario

Rather, a first overlap relationship may be determined based on which SSB occasions of the SC SSB configuration and SSB occasions of the NSC SSB configuration fully or partially overlap with one another outside of occasions of the MG configuration and occasions of the SMTC. The intermediate sharing factor may be determined based on the first overlap relationship.

The final sharing factor may be determined based on the intermediate sharing factor and the overlapping relationship determined at 1108 (the second overlapping relationship with respect to scenarios 6 and 7) . In particular, the overlapping relationship determined at 1108 may be used to select one of the four cases described above for determining the final sharing factor based on the intermediate sharing factor.

The periodicity relationship may be among at least two periodicities that include a first periodicity associated with the SC SSB configuration, a second periodicity associated with the NSC SSB configuration, a third periodicity of the SMTC, or a fourth periodicity of the MG configuration. The periodicity relationship determined may be one of those referenced in any one of scenarios 1–5 of Tables 600.

The overlap number may be determined with respect to a time period equal to max(MGRP, T _SMTC) . The overlap number may correspond to SSB _SC1, SSB _CDP1, SSB _SC2, or SSB _CDP2 discussed above with respect to FIG. 6.

The operation flow/algorithmic structure 1200 may further include, at 1212, determining a final sharing factor. The final sharing factor may be based on the periodicity relationship and the overlap number. In particular, the periodicity relationship may be used to select a scenario from Table 600 and the overlap number may be used in a corresponding formula from the selected scenario.

The operation flow/algorithmic structure 1300 may include, at 1304, transmitting information to configure SC/NSC SSB configurations, the MG configuration, and the SMTC.

The operation flow/algorithmic structure 1300 may further include, at 1308, determining a sharing factor. The sharing factor may be determined in a manner similar to that discussed elsewhere herein. For example, the base station may first determine an intermediate sharing factor and then determine a final sharing factor as described above with respect to Tables 200 and 300. Alternatively, the base station may derive the final sharing factor directly as described above with respect to Table 600.

The operation flow/algorithmic structure 1300 may further include, at 1312, determining an L1 measurement period based on the sharing factor. The base station may determine the L1 measurement period in a manner similar to that described elsewhere herein.

The base station may expect reporting of L1-RSRP measurements for the L1 measurement period. In the event that no measurements are received, the base station may assume there has been a link or beam failure and may proceed to perform link/beam recovery or reconfiguration operations.
