[0028] Figure 1 A network environment 100 according to some embodiments is illustrated. Network environment 100 may include a UE 104 and a base station 108. Base station 108 may provide a serving cell 110 through which UE 104 can communicate with base station 108. In some embodiments, base station 108 is a next-generation node B (gNB) providing one or more 3GPP New Radio (NR) cells. In other embodiments, base station 108 is an evolved Node B (eNB) providing one or more Long Term Evolution (LTE) cells. The air interface through which UE 104 and base station 108 communicate may be compatible with 3GPP technical specifications, such as those defining the fifth-generation (5G) NR system standard.

[0029] Network environment 100 may also include one or more adjacent base stations, such as base stations 116 and 124, which respectively provide non-serving cells 112 and 120. Base stations 116 and 124 may use the same radio access technology as base station 108 or a different radio access technology.

[0030] To adapt to changes in the radio environment and the relative positioning between UE 104 and the base station, UE 104 can be configured to perform various measurements on reference signals transmitted in serving cell 110 and non-serving cells 112 and 120. Base station 108 can transmit measurement configurations to provide UE 104 with information for performing reference signal measurements. During measurement execution, UE 104 can provide measurement reports to base station 108. Base station 108 can perform various radio resource management (RRM) operations based on the measurement reports.

[0031] The measurement configuration can instruct UE 104 to perform intra-frequency measurements based on reference signals, including, for example, synchronization signals and physical broadcast channel block (SSB) resources. Measurements can be beam-level or cell-level. SSB intra-frequency measurements can correspond to a scenario where serving cell 110, non-serving cell 112, and non-serving cell 120 use the same SSB center frequency and subcarrier spacing.

[0032] When UE 104 is in Radio Resource Control (RRC) connection mode, measurement configuration can be transmitted to UE 104 via dedicated signaling (such as RRC signaling, e.g., RRC reconfiguration message or RRC recovery message).

[0033] In some implementations, the measurement configuration may include (directly or by reference) a measurement identity, a measurement object, and a reporting configuration. The measurement identity associates the reporting configuration with the measurement object. The measurement identity may include a first pointer toward the reporting configuration and a second pointer toward the measurement object, which provides information about the SSB resource to be measured. UE 104 may provide the measurement results within an RRC message (e.g., an RRC measurement report) that includes the measurement ID as a reference.

[0034] Reporting configurations can provide periodic, event-triggered, or Cell Global Identity (CGI) configurations. Reporting configurations can include parameters such as reporting quantity, reporting interval, and, if the configuration is event-triggered, measurement reporting events. Reporting quantity and reporting interval can be Abstract Syntax Mark 1 (ASN.1) fields in the Reporting Configuration Information Element (IE). The reporting quantity describes the number of times a measurement report is transmitted based on a triggering event. A triggering event can be the consumption of a period (for periodic configurations) or the fulfillment of a triggering condition for a measurement reporting event (for event-triggered configurations). The reporting interval provides the time between consecutive transmissions of measurement reports. Reporting configurations can also describe the type of reference signal (e.g., SSB) that can be used for periodic or event-triggered configurations.

[0035] SSB can be used to measure the reference signal received power (RSRP) at either Layer 1 (L1) or Layer 3 (L3). Compared to L3 measurements, L1 measurements can be used to monitor and respond to radio channel conditions over shorter time frames. L1 measurements can be used, for example, to perform beam management procedures, while L3 measurements can be used, for example, to perform handover procedures.

[0036] Typically, UE 104 may perform L1 measurements only for serving cell 110 for beam management. However, in some cases, such as when base stations 116 and 124 correspond to multiple transmit / receive points (multiple TRPs), UE 104 may perform L1 measurements for both serving cell 110 and non-serving cells 112 and 120 for beam management. When UE 104 measures different cells, it may need to use different beams. This may be especially true when UE 104 operates in a higher frequency range (e.g., frequency range 2 (FR2) from 24.25 GHz to 52.6 GHz or higher). Therefore, when measurement opportunities for SSBs for serving cell (SC) and non-serving cell (NSC) conflict, UE 104 may need to select which cell to measure. Various implementations describe how measurement opportunities can be shared between L1 and L3 measurements.

[0037] The measurement configuration defines the periodicity, offset, and duration of measurement opportunities available for SSB-based L1 / L3 measurements. The SSB Measurement Timing Configuration (SMTC) defines the measurement opportunities used to perform L3 measurements.

[0038] Measurement opportunities for performing L1-RSRP measurements on the serving cell can be defined at least in part by T_SSB,SC, where T_SSB,SC represents the periodicity of the SSB index configured for L1 RSRP measurements on the SC. Similarly, measurement opportunities for performing L1-RSRP measurements on the serving cell can be defined at least in part by T_SSB,NSC, where T_SSB,NSC represents the periodicity of the SSB index configured for L1 RSRP measurements on the NSC. Likewise, measurement opportunities for performing L3-RSRP measurements on the serving cell can be defined at least in part by T_SSB,SC, where T_SSB,SC represents the periodicity of the SSB index configured for L3 RSRP measurements.

[0039] In some implementations, L1 measurement opportunities (and potentially L3 measurement opportunities) can be configured in an aligned manner such that at least some instances of one type of measurement opportunity overlap with at least some instances of other types of measurement opportunities. This can be achieved by configuring measurement opportunities with a common offset and duration (e.g., SSB burst set length) and aligned periodicity (e.g., one periodicity is equal to or a multiple of another periodicity). An SSB or an SSB burst set (if the SSB burst set length is greater than 1) can be transmitted by the SC / NSC within a measurement opportunity.

[0040] Figure 2 Various measurement opportunities 200 according to some embodiments are illustrated. Measurement opportunity 200 may include an L1 SC measurement opportunity 204 for performing L1-RSRP measurements on the serving cell. L1 SC measurement opportunity 204 may have a periodicity equal to T_SSB,SC. Measurement opportunity 200 may also include an L1 NSC measurement opportunity 208 for performing L1-RSRP measurements on an NSC. L1 NSC measurement opportunity 208 may have a periodicity equal to T_SSB,NSC. Measurement opportunity 200 may also include an L3 measurement opportunity 212 for performing L3-RSRP measurements. L3 measurement opportunity 212 may have a periodicity equal to T_SMTC. As shown, T_SSB,SC = T_SSB,NSC <T_SMTC。

[0041] At instances 216 and 220 (e.g., which could be subframes), L1 SC measurement opportunities conflict with both L1 NSC and L3 measurement opportunities; and at instances 218 and 222, L1 SC measurement opportunities may conflict with L1 NSC measurement opportunities. At each instance, UE 104 may need to determine which measurements to perform in which overlapping measurement opportunities.

[0042] Clause 9.5.4 of 3GPP TS 38.133v17.5.0 (2022-03) defines a sharing factor P, which informs UE 104 how to share L1-RSRP and L3-RSPR measurement opportunities with measurement gaps. Since P is at least partially related to the sharing between L1 and L3 measurement opportunities, it may be referred to herein as an inter-layer sharing factor, where L1 and L3 measurements are considered to be on different layers. Embodiments of this disclosure provide an additional sharing factor P_L1, which informs UE 104 how to share L1 measurement opportunities belonging to the serving cell and non-serving cells. Since P_L1 is related to the sharing between L1 measurement opportunities, it may be referred to herein as an intra-layer sharing factor.

[0043] The intra-layer sharing factor can be based on several factors, including whether SC measurements take precedence over NSC measurements and the number of NSCs configured for measurement. Generally, the intra-layer sharing factor indicates how many available measurement opportunities are needed to perform an L1 measurement. For example, if the intra-layer sharing factor is 1, UE 104 can perform one L1 measurement in every available measurement opportunity; if the intra-layer sharing factor is 2, UE 104 can perform one L1 measurement in every two available measurement opportunities, and so on. As used herein, measurement opportunities available for L1 measurement can refer to L1 measurement opportunities outside of SMTCs.

[0044] In implementations where T_SSB,SC equals T_SSB,NSC and they are both less than T_SMTC (e.g.) Figure 2 As shown in the diagram, the intra-layer sharing factor P_L1 of the SC can be defined as follows:

[0045] P_L1 = 1 + k * N_NSC, Equation 1

[0046] Where k is the weighting factor, and N_NSC is the number of NSCs configured for measurement.

[0047] The weighting factor k can be set using a value associated with the relative priority given between SC and NSC measurements. For example, if SC measurements take precedence over NSC measurements, k can be less than 1; if NSC measurements take precedence over SC measurements, k can be greater than 1; if SC and NSC measurements have equal priority (e.g., equally share measurement opportunities), k can be equal to 1. In various implementations, k can be predefined by the 3GPP TS, determined by the network and provided to UE 104, or determined by UE 104 and provided to the network.

[0048] UE 104 can use P_L1 of the SC to select a subset of the total number of available L1 SC measurement opportunities 204, which can be used to perform L1-RSRP measurements on the SSB transmitted by the SC.

[0049] In implementations where T_SSB,SC equals T_SSB,NSC and they are both less than T_SMTC (e.g.) Figure 2 As shown in the diagram, the intra-layer sharing factor P_L1 of NSC can be defined as follows:

[0050] P_L1 = (1 + k * N_NSC) / k, Equation 2

[0051] Where k and N_NSC are defined similarly to those described above with respect to Equation 1. UE 104 can use P_L1 of the NSC to select a subset of the total number of available L1 NSC measurement opportunities 208, which can be used to perform L1-RSRP measurements on the SSB transmitted by the NSC.

[0052] Figure 3 Various measurement opportunities 300 according to some embodiments are illustrated. Measurement opportunity 300 may include an L1 SC measurement opportunity 304 for performing L1-RSRP measurements on the serving cell. L1 SC measurement opportunity 304 may have a periodicity equal to T_SSB,SC. Measurement opportunity 300 may also include an L1 NSC measurement opportunity 308 for performing L1-RSRP measurements on an NSC. L1 NSC measurement opportunity 308 may have a periodicity equal to T_SSB,NSC. Measurement opportunity 300 may also include an L3 measurement opportunity 312 for performing L3-RSRP measurements. L3 measurement opportunity 312 may have a periodicity equal to T_SMTC. As shown, T_SSB,NSC <T_SSB,SC=T_SMTC。

[0053] At instances 316 and 320 (e.g., which could be subframes), L1 SC measurement opportunities conflict with both L1 NSC and L3 measurement opportunities; at instances 318 and 322, L1 NSC measurement opportunities may not conflict with any other measurement opportunities. At each instance, UE 104 may need to determine which measurements to perform in which of the overlapping measurement opportunities.

[0054] In these implementations, the intra-layer sharing factor P_L1 of the SC can be set to 1. Therefore, UE 104 can use all available L1 SC measurement opportunities (e.g., all L1 SC measurement opportunities outside the SMTC) to perform L1-RSRP measurements on the SSB transmitted by that SC. This is likely desirable given that L1 SC measurement opportunities are less dense than NSC measurement opportunities.

[0055] The P_L1 of the NSC is set to be equal to N_NSC. For example, if only one NSC is configured for measurement, the P_L1 of the NSC can be equal to 1, and UE 104 can use all available L1 NSC measurement opportunities (e.g., L1 NSC measurement opportunities other than SMTC) to perform L1-RSRP measurements on the SSB transmitted by that NSC. If two NSCs are configured for measurement, the P_L1 of the NSC can be equal to 2, and UE 104 can use one of every two L1 NSC measurement opportunities to perform L1-RSRP measurements on the SSB transmitted by that NSC.

[0056] Figure 4 and Figure 5 The diagram illustrates all the measurement opportunities where the periodicity differs from each other. In these embodiments, an NSC can be configured for measurement (e.g., N_NSC = 1), and the intra-layer shared factor can be determined as follows.

[0057] Figure 4 Various measurement opportunities 400 according to some embodiments are illustrated. Measurement opportunity 400 may include an L1 SC measurement opportunity 404 for performing L1-RSRP measurements on the serving cell. L1 SC measurement opportunity 404 may have a periodicity equal to T_SSB,SC. Measurement opportunity 400 may also include an L1 NSC measurement opportunity 408 for performing L1-RSRP measurements on an NSC. L1 NSC measurement opportunity 408 may have a periodicity equal to T_SSB,NSC. Measurement opportunity 400 may also include an L3 measurement opportunity 412 for performing L3-RSRP measurements. L3 measurement opportunity 412 may have a periodicity equal to T_SMTC. As shown, T_SSB,SC <T_SSB,NSC<T_SMTC。

[0058] At instances 416 and 424 (e.g., which could be subframes), L1 SC measurement opportunities conflict with both L1 NSC and L3 measurement opportunities. At instances 420 and 428, L1 SC measurement opportunities may conflict with L3 measurement opportunities. Furthermore, at instances 418, 422, and 426, L1 SC measurement opportunities may not conflict with either L1 NSC or L3 measurement opportunities. At each instance, UE 104 may need to determine which measurements to perform in which of the overlapping measurement opportunities.

[0059] In these implementations, the intra-layer sharing factor P_L1 of SC can be defined as (1-T_SSB,SC / T_SMTC)) / (1-(T_SSB,SC / T_SSB,NSC)).

[0060] In these implementations, the intra-layer sharing factor P_L1 of the NSC can be set to 1. Therefore, UE 104 can use all available L1 NSC measurement opportunities (e.g., L1 SC measurement opportunities outside the SMTC) to perform L1-RSRP measurements on the SSB transmitted by that NSC. This is likely desirable given that L1 SC measurement opportunities are less dense than NSC measurement opportunities.

[0061] Based on these definitions of intra-layer shared factors, when the SSB burst sets of the SC and NSC partially overlap, cells with fewer SSB burst set periodicity will only be measured if the SSB burst sets of the SC and NSC do not conflict. For example, refer to... Figure 4Since TS_SSB,SC is shorter than T_SSB,NSC, when the L1 SC measurement opportunity does not overlap with the L1 NSC SC measurement opportunity (e.g., examples 418, 422, and 426), the L1 SC measurement opportunity can be used only to measure the SSB transmitted by that SC.

[0062] Figure 5 Various measurement opportunities 500 according to some embodiments are illustrated. Measurement opportunity 500 may include an L1 SC measurement opportunity 504 for performing L1-RSRP measurements on the serving cell. L1 SC measurement opportunity 504 may have a periodicity equal to T_SSB,SC. Measurement opportunity 500 may also include an L1 NSC measurement opportunity 508 for performing L1-RSRP measurements on an NSC. L1 NSC measurement opportunity 508 may have a periodicity equal to T_SSB,NSC. Measurement opportunity 500 may also include an L3 measurement opportunity 512 for performing L3-RSRP measurements. L3 measurement opportunity 512 may have a periodicity equal to T_SMTC. As shown, T_SSB,NSC <T_SSB,SC<T_SMTC。

[0063] At instances 516 and 524 (e.g., which could be subframes), L1 SC measurement opportunities conflict with both L1 NSC and L3 measurement opportunities. At instances 520 and 528, L1 SC measurement opportunities may conflict with L3 measurement opportunities. Furthermore, at instances 518, 522, and 526, L1 NSC measurement opportunities may not conflict with either L1 NSC or L3 measurement opportunities. At each instance, UE 104 may need to determine which measurements to perform in which of the overlapping measurement opportunities.

[0064] In these implementations, the intra-layer sharing factor P_L1 of NSC can be defined as (1-T_SSB,NSC / T_SMTC)) / (1-(T_SSB,NSC / T_SSB,SC)).

[0065] In these implementations, the intra-layer sharing factor P_L1 of the SC can be set to equal 1. Therefore, UE 104 can use all available L1 SC measurement opportunities (e.g., measurement opportunities outside the SMTC) to perform L1-RSRP measurements on the SSB transmitted by that SC. This is likely desirable given that L1 SC measurement opportunities are less dense than other measurement opportunities.

[0066] Similar to the reference above Figure 4 As described, based on these definitions of intra-layer shared factors, when the SSB burst sets of the SC and NSC partially overlap, cells with fewer SSB burst set periodicity will only be measured if the SSB burst sets of the SC and NSC do not conflict. For example, refer to... Figure 5 Since TS_SSB,NSC is shorter than T_SSB,SC, when the L1 NSC measurement opportunity does not overlap with the L1 SC measurement opportunity (e.g., examples 518, 522, and 526), ​​the L1 NSC measurement opportunity can be used only to measure the SSB transmitted by that NSC.

[0067] To comply with Clause 9.5.4 of 3GPP TS 38.133, the physical layer of UE 104 may need to be able to report L1-RSRP measurements within the L1 measurement period T_L1-RSRP_Measurement_Period_SSB. If UE 104 fails to report the configured L1-RSRP measurements within the L1 measurement period, base station 108 may determine that there is a beam or radio link failure and attempt to perform radio resource management (RRM) operations, such as configuring a new beam or cell.

[0068] 3GPP TS 38.133 currently bases L1 measurement periods on inter-layer shared factors. The embodiments of this disclosure are described below using intra-layer shared factors as an additional basis for determining L1 measurement periods.

[0069] In FR2, when considering the intra-frequency L1 measurement of the NSC, the L1 measurement period can be determined as follows. Unless described elsewhere in this document, the parameters used to calculate the L1 measurement period may be similarly named parameters as in Clause 9.5.4.1 of 3GPP TS 38.133.

[0070] If UE 104 does not operate according to the Discontinuous Receive (DRX) configuration, the L1 measurement period can be equal to max(T_report,ceil(M*P*N*P_L1)*T_SSB). T_report can be the configured periodicity for reporting, T_SSB can be the periodicity of the SSB index configured for L1-RSRP measurements in SC or NSC, T_DRX is the DRX cycle length, M equals 1 if a time limit is configured for the channel measurement parameters, otherwise M equals 3, P is the inter-layer sharing factor, and N is 8.

[0071] If UE 104 operates according to a DRX configuration of no more than 320 milliseconds, the L1 measurement period may be equal to max(T_report,ceil(1.5*M*P*N*P_L1)*max(T_DRX,T_SSB). These parameters may be similar to those described above, and are described in Clause 9.5.4.1 of TS 38.133, except for P_L1.

[0072] If the UE 104 operates according to a DRX configuration exceeding 320 milliseconds, the L1 measurement period may be equal to ceil(1.5*M*P*N*P_L1)*T_DRX. These parameters may be similar to the parameters described above, except for P_L1 described in clause 9.5.4.1 of TS 38.133.

[0073] In some embodiments, the L1 measurement period may be determined relative to the high-speed environment by making similar modifications to Table 9.5.4.1-3 of TS 38.133 (e.g., incorporating P_L1).

[0074] Figure 6 illustrates an operational flow / algorithm structure 600 in accordance with some aspects. The operational flow / algorithm structure 600 may be performed or implemented by a UE, such as UE 104 or 900, or a component thereof (e.g., baseband processor circuitry 904A).

[0075] The operational flow / algorithm structure 600 may include, at 604, receiving information for configuring SSB-based intra-frequency measurements relative to a plurality of NSCs. The measurements may be L1-RSRP measurements configured for one or more NSCs. In some embodiments, this information may be received in one or more configuration messages, and may further configure other L1 measurements such as L1-RSRP measurements of SBS for SC as well as L3 measurements. This information may provide various periodicity information, such as, for example, T_SSB,SC, T_SSB,NSC and T_SMTC.

[0076] The operational flow / algorithm structure 600 may further include, at 608, determining that T_SSB,SC = T_SSB,NSC < T_SMTC. Accordingly, the L1 measurement opportunities may be configured with the same periodicity, and this periodicity may be smaller than the periodicity of the L3 measurement opportunities.

[0077] The operational flow / algorithm structure 600 may further include, at 612, determining a weighting factor. As described above, the weighting factor k may be set using a value associated with the relative priority given between SC measurements and NSC measurements. For example, k may be less than 1 if SC measurements take priority over NSC measurements; k may be greater than 1 if SC measurements are deprioritized (e.g., NSC measurements take priority over SC measurements); k may be equal to 1 if SC measurements and NSC measurements have equal priority (e.g., measurement opportunities are shared equally). In various embodiments, k may be predefined by 3GPP TS, determined by the network and provided to the UE in configuration information, or determined by the UE 104.

[0078] The operational flow / algorithm structure 600 may further include, at 616, determining an intra-layer sharing factor. This determination may be based on the number of NSCs configured for measurement and the weighting factor.

[0079] The intra-layer sharing factor of the SC can be set to equal 1 + k * N_NSC. Then, the UE can use the intra-layer sharing factor of the SC to select a subset of multiple available L1 SC measurement opportunities and perform L1 measurements of the SC within that subset.

[0080] The UE can also determine the intra-layer sharing factor of the NSC as equal to (1+k*N_NSC) / k. The UE can then use the intra-layer sharing factor of the NSC to select a subset of multiple available L1 NSC measurement opportunities and perform L1 measurements of the NSC within that subset. In this implementation, multiple L1 SC measurements may correspond to L1 NSC measurement opportunities.

[0081] Figure 7 An operational flow / algorithm structure 700 is illustrated based on some aspects. The operational flow / algorithm structure 700 may be executed or implemented by a UE such as UE 104 or 900, or its components (e.g., baseband processor circuitry 904A).

[0082] The operation flow / algorithm structure 700 may include, at 704, receiving information for configuring SSB-based intra-frequency measurements relative to multiple NSCs. The received information may be similar to that elsewhere in this document (including, for example...). Figure 6 The information described in the operation process / algorithm structure (600).

[0083] The operation flow / algorithm structure 700 may further include: at 708, determining that T_SSB,SC is not equal to T_SSB,NSC, and that both T_SSB,SC and T_SSB,NSC are less than T_SMTC. Therefore, L1 measurement opportunities can be configured with different periodicities, both of which can be less than the periodicity of L3 measurement opportunities.

[0084] The operation flow / algorithm structure 700 may also include: at 712, determining a ratio. This ratio may be the ratio of one L1 measurement periodicity to the L3 measurement periodicity in the L1 measurement periodicity.

[0085] The operation process / algorithm structure 700 may also include: at 716, determining the intra-layer sharing factor based on the ratio determined at 712.

[0086] When T_SSB,SC is less than T_SSB,NSC, the ratio can be T_SSB,SC to T_SMTC. In this embodiment, the intra-layer scaling factor of SC can be defined as (1-(T_SSB,SC / T_SMTC)) / (1-(T_SSB,SC / T_SSB,NSC)). The UE can then use the intra-layer shared factor of SC to select a subset of multiple available L1 SC measurement opportunities and perform L1 measurements of SC within that subset. The intra-layer shared factor of NSC can be set to equal 1. The UE can then use the intra-layer shared factor of NSC to select a subset of multiple available L1 NSC measurement opportunities and perform L1 measurements of NSC within that subset.

[0087] When T_SSB,SC is greater than T_SSB,NSC, the ratio can be the ratio of T_SSB,NSC to T_SMTC. In this implementation, the intra-layer scaling factor of NSC can be defined as (1-(T_SSB,NSC / T_SMTC)) / (1-(T_SSB,NSC / T_SSB,SC)). The UE can then use the intra-layer shared factor of NSC to select a subset of multiple available L1 NSC measurement opportunities and perform L1 measurements of NSC within that subset. The intra-layer shared factor of SC can be set to equal 1. The UE can then use the intra-layer shared factor of SC to select a subset of multiple available L1 SC measurement opportunities and perform L1 measurements of SC within that subset.

[0088] Figure 8 An operational flow / algorithm structure 800 is shown according to some aspects. The operational flow / algorithm structure 800 may be executed or implemented by a serving base station such as base station 108 or network node 1000, or its components (e.g., baseband processor circuit 1004A).

[0089] The operation flow / algorithm structure 800 may include, at 804, transmitting information for configuring SSB-based intra-frequency measurements relative to multiple NSCs. The transmitted configuration information may be similar to other parts of this document (including, for example...). Figure 6 The received configuration information is described in the operation process / algorithm structure (600).

[0090] The operation flow / algorithm structure 800 may also include: at 808, determining the intra-layer sharing factor based on the weighting factor and the number of NSCs. The base station may be similar to other parts of this document (including, for example...). Figure 6 The operation process / algorithm structure (600) describes the way to determine the sharing factor within the layer.

[0091] The operation flow / algorithm structure 800 may further include: at 812, determining the L1 measurement period based on the intra-layer shared factor. The base station can determine the L1 measurement period in a manner similar to that described elsewhere in this document (including, for example),

[0092] The base station can determine the L1 measurement period based on the DRX configuration provided to the UE. If no DRX configuration is provided, the L1 measurement period can be equal to max(T_report,ceil(M*P*N*P_L1)*T_SSB). T_report can be the configured periodicity for reporting, T_SSB can be the periodicity of the SSB index configured for L1-RSRP measurements in SC or NSC, T_DRX is the DRX cycle length, M equals 1 if a time limit is configured for the channel measurement parameters, otherwise M equals 3, P is the inter-layer sharing factor, and N is 8.

[0093] If the DRX configuration does not exceed 320 milliseconds, the L1 measurement period can be equal to max(T_report,ceil(1.5*M*P*N*P_L1)*max(T_DRX,T_SSB). These parameters can be similar to those described above, except for P_L1 as described in Clause 9.5.4.1 of TS 38.133.

[0094] If the DRX configuration is greater than 320 milliseconds, the L1 measurement period can be equal to ceil(1.5*M*P*N*P_L1)*T_DRX. These parameters can be similar to those described above, except for P_L1 as described in Clause 9.5.4.1 of TS 38.133.

[0095] The base station can expect to report L1-RSRP measurements during the L1 measurement cycle. If no measurement is received, the base station can assume that a link or beam failure has occurred and can continue to perform link / beam recovery or reconfiguration operations.

This signal can be provided to the receiver of the transceiver, which downconverts the RF signal into a baseband signal that is provided to the baseband processor of processor 904.

[0106] In the transmission path, the transceiver's transmitter upconverts the baseband signal received from the baseband processor and provides the RF signal to the RFEM.
