Description

Background Art

[0002] In order to better implement mobility switching for terminal devices, the network can configure the terminal devices to measure the reference signals of the same-frequency, different-frequency or different-network target neighboring cells in a specific time window. The specific time window can be called a measurement gap (Measurement Gap, MG, sometimes referred to as a gap). There are many reference signals for measurement, such as synchronization signal block (Synchronization Signal Block, SSB), channel state information reference signal (CSI-RS), positioning reference signals (Positioning reference signals, PRS), and so on. In terms of measurement configuration, in order to limit the configuration used to measure SSB in the time domain, the SSB measurement time configuration window SMTC is defined. For example, for CSI-RS measurement, since the CSI-RS resource itself is highly flexible and has periodic and non-periodic characteristics, how to set appropriate restrictions on the measurement of reference signals such as CSI-RS is still under study and optimization.

[0036] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" is used to describe the association relationship of associated objects. For example, it means that there are three kinds of relationships between the associated objects. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " in this article generally means that the associated objects are in an "or" relationship.

[0037] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect corresponding relationship between two entities, or may indicate an associated relationship between them, or may be a relationship such as indication and being indicated, configuration and being configured, etc.

[0038] To clearly elaborate on the concept of the embodiments of the present application, first, a brief description is given of the scaling of measurement time in a communication system and the related content of the carrier specific scaling factor (CSSF).

[0039] The scaling of measurement time is to meet certain measurement accuracy requirements. For UE's intra-frequency or inter-frequency measurements, sufficient reference signal samples need to be obtained within the unit measurement time, and the relevant measurement results are evaluated and reported to the network. Among them, SSBs outside the SSB-based RRM Measurement Timing Configuration window (SMTC) configured for the UE are not considered for RRM measurements. Since intra-frequency or inter-frequency measurements can support measurements with or without gaps configured, the corresponding SMTC and measurement gaps may not completely overlap. Considering the overlapping relationship between the current SMTC and the per-UE or per-FR gap configured by the network, there are three cases: non-overlap, complete overlap, or partial overlap, between the length and period of the measurement reference signal and the length and period of the measurement gap. Therefore, different scaling requirements need to be defined for the measurement period respectively to meet the measurement accuracy requirements.

[0040] Taking the SSB-based measurement as an example, the scaling of measurement time can include two types: one is the scaling of measurement time only applicable to measurements without measurement gaps, characterized by Kp; the other is the CSSF for UEs with carrier aggregation capabilities inside and outside the gap, which is used to relax the measurement time for various intra-frequency or inter-frequency measurements. Specifically, the definition of the measurement time scaling Kp applicable to intra-frequency or inter-frequency measurements without gaps satisfies the following cases:

[0041] · If the SMTC is entirely inside or outside the gap, then the intra-frequency measurement without a gap is either entirely inside or outside the gap and no additional relaxation is required, Kp = 1;

[0042] · If the SMTC partially overlaps with the gap and the SMTC period < MGRP, then the intra-frequency measurement without a gap needs to lengthen the measurement time to ensure a sufficient number of measurement reference signal samples, and the lengthening factor Kp = 1 / (1 - (SMTC period / MGRP));

[0043] If SMTC and gap partially overlap and SMTC period>MGRP, the protocol does not clearly define the time requirement for UE measurement, which is within the scope of UE implementation.

[0044] Time scaling for multi-carrier measurements in and out of the gap, including CSSF, for measurements outside the gap and measurements in the gap (including co-frequency measurements or inter-frequency measurements) outside_gap and CSSF within_gap .

[0045] Among them, CSSF outside_gap Applicable to UEs that allow out-of-gap measurements, when the SMTC configured for the measurement that does not require the UE to have partial overlap or no overlap with the gap configured by the current UE, the relaxation adjustment of the UE measurement time is made. When the UE has carrier aggregation CA capability, it is considered that the UE can handle the measurement of up to two carriers at the same time. When the UE needs to measure the same frequency, different frequency or different system frequency points of multiple carriers NR at the same time, the CSSF can be defined for the relaxation of the same frequency or different frequency measurement time according to the number of measured carriers.

[0046] Among them, CSSF within_gap Applicable to the case where the UE needs to configure gap measurements, or the SMTC configured for measurements of co-frequency or inter-frequency points that do not require gaps completely overlaps with the current per UE or per FR configured gap, and the UE measurement time is relaxed. The CSSF is determined based on the gap sharing scheme (measGapSharingScheme) currently configured by the UE and the number of co-frequency or inter-frequency measurement objects MO that need to be measured in the gap. within_gap .

[0047] For example, when the gap sharing scheme is equal sharing, the scaling factors of the same-frequency and different-frequency measurements are the same, and the scaling factors of the same-frequency and different-frequency or different-system measurement time can be obtained. Then, the measurement time scaling factors CSSF of the same-frequency and different-frequency or different-system measurement objects in the gap can be calculated respectively. within_gap .

[0100] Method 1: Independent configuration of CMTC for CSI-RS and SMTC for SSB

[0101] Step 1: The network device may configure the time window CMTC for CSI-RS measurement for the UE, which may include at least the CMTC periodicity, length duration and offset. As an example periodicity, a possible configuration is as follows:

[0102] · 1 CMTC periodicity: {10,20,40}ms

[0103] · 1 CMTC duration: {1,2,3,4,5}ms

[0104] · 1 CMTC offset: {10,20,40}ms

[0105] Step 2: The UE calculates the system frame number (SFN) and subframe where the CSI-RS of the adjacent cell is located, that is, the starting position of the CMTC, based on the CMTC periodicity and Offset.

[0106] Step 3: The UE performs CSI-RS measurement in the CMTC window.

[0107] Step 4: Determine the carrier-level scaling requirement for the UE measurement time based on the UE's ability to support simultaneous measurement of carriers (i.e., the maximum number of carrier frequencies or searchers that can be measured simultaneously), and use CSSF outsidegap express.

[0108] Step 5: At intervals of measurement time, the UE reports the measurement results to the network periodically, aperiodically, or in an event-triggered manner.

[0109] Method 2: CSI-RS uses SMTC of SSB

[0110] Step 1: The network device may configure the time window SMTC for SSB measurement for the UE, which may at least include the periodicity, length duration and offset of the SMTC.

[0111] Step 2: The UE calculates the SFN and Subframe where the SSB or CSI-RS of the adjacent cell is located based on the SMTC periodicity and Offset, that is, the starting position of the SMTC.

[0112] Step 3: The UE performs SSB and CSI-RS measurements in the SMTC window.

[0113] Step 4: Determine the carrier-level scaling requirement of the UE measurement time based on the UE's ability to support simultaneous measurement of carriers, such as CSSF outsidegap .

[0114] Step 5: At intervals of measurement time, the UE reports the measurement results to the network periodically, aperiodically, or event-triggered.

[0115] In some embodiments of the present application, in Mode 1 and Mode 2, the UE may also report the supported searcher capabilities to the network, and the network may also obtain the scaled measurement time requirement accordingly.

[0116] Mode 1 and Mode 2 provide the measurement process of CSI-RS measurement under different time domain configurations, solve the problem of time domain configuration constraints for CSI-RS measurement, reduce the problem of overly flexible CSI-RS resource configuration, reduce implementation complexity, and improve measurement efficiency.

[0117] For Method 1 and Method 2, the measurement restriction requirements mentioned in Step 4 above may be determined based on at least one of the following conditions or situations:

[0118] (1) Whether UE capabilities are shared by SSB measurement and CSI-RS measurement;

[0119] (2) Whether the SSB measurement and CSI-RS measurement are located outside or inside the gap;

[0120] (3) Whether the UE measures CSI-RS or SSB simultaneously in the same measurement window.

[0121] Figure 3The multi-frequency point time domain configuration of CSI-RS measurement and SSB measurement in the embodiment of the present application is schematically shown. Figure 3 , based on multiple specific examples, the processing process under different conditions or situations is described in detail.

[0122] Method 3: Outside the measurement gap (depending on the number of measurement frequency points)

[0123] According to the downlink carrier aggregation capability of the carrier where the frequency of the cell being measured is located, it is determined whether the UE can simultaneously receive the corresponding frequency. It is assumed that at least one frequency is to be measured on each carrier, that is, at least one neighboring cell is to be measured.

[0124] I. Mode 3-1: When the UE performs only CSI-RS measurement or SSB measurement outside the gap, such as Figure 3 If f2 of CSI-RS and fb of SSB do not meet each other, it is not necessary to consider whether CSI-RS measurement and SSB measurement share the multi-carrier capability of UE. At least one of the following methods can be used to determine the time limit of CSI-RS measurement or SSB measurement according to the capability of measurement searcher corresponding to the multi-carrier capability supported by UE:

[0125] ●For FR1 only CA, the FR1 measurement searcher capability is M1, the CSSF of the primary carrier for CSI-RS measurement is 1, and the number of CSSF secondary carriers corresponding to the secondary carrier is divided by (M1-1), or X / (M1-1), where X is the CSSF of the SSB. For example, X can be the value of the CSSF of the SSB in Rel-15.

[0126] ●For FR2 intra or inter only CA, the FR2 measurement searcher capacity is M2, the CSSF of the primary carrier PCC for CSI-RS measurement is still 1, and the CSSF corresponding to the secondary carrier SCC is the number of secondary carriers divided by (M2-1), or X / (M2-1).

[0127] ●For FR1+FR2 CA, if the searcher for FR1 and FR2 measurements is shared, and the UE supports M searcher measurements, of which the searcher capacity allocated to FR1 measurement is M3 and the searcher capacity allocated to FR2 measurement is M4, then the CSSF of the FR1 primary carrier PCC for CSI-RS measurement is still 1, and the CSSF corresponding to the FR1 secondary carrier SCC is 2×(N configuredSCell -1) / (M3-1), the CSSF corresponding to the FR2 secondary carrier SCC is 2×(N configuredSCell -1) / (M4-1). Where, N configuredSCellIndicates the total number of configured scells on all carriers in FR1 and FR2 used for CSI-RS measurement.

[0128] ●For FR1+FR2 CA, if the searchers for FR1 and FR2 measurements are not shared, the searcher capacity allocated to FR1 measurement is M8, and the searcher capacity allocated to FR2 measurement is M9. The CSSF of the FR1 primary carrier PCC measured by CSI-RS is still 1, and the CSSF corresponding to the FR1 secondary carrier SCC is (N configuredFR1SCell -1) / (M8-1), the CSSF corresponding to the FR2 secondary carrier SCC is (N configuredFR2SCell -1) / (M9-1). Where, N configuredFR1SCell Indicates the number of scells configured on the FR1 carrier for CSI-RS measurement; N configuredFR2SCell Indicates the number of configured scells on the FR2 carrier used for CSI-RS measurement.

[0129] Table 1

[0130]

[0131] Table 1 lists the CSSF corresponding to the CSI-RS of the UE determined in the above-mentioned various ways. outside .

[0132] In addition, as an example, if the number of searchers assigned to FR1 measurement is 2, the CSSF of CSI-RS follows the CSSF requirements of SSB. As an example, if the UE does not support the new measurement searcher capability, the CSSF of CSI-RS follows the CSSF requirements of SSB.

[0133] II. Mode 3-2: When the UE performs CSI-RS measurement and SSB measurement simultaneously outside the gap, such as Figure 3 The measurement windows of f1 and f3 of CSI-RS and fa and fc of SSB respectively coincide with each other. At least one of the following methods can be used to determine the time limit of CSI-RS measurement or SSB measurement:

[0134] ● If the searcher capabilities for CSI-RS measurement and SSB measurement are not shared, the searcher measurement capability (which can be represented by M, representing the number of searchers) of the multi-carrier capability supported by the UE (including the UE supporting at least one of per FR1, perFR2, UE level (perUE), RS level (perRS)) is configured in a per RS ​​manner for measuring reference signals, and the CSI-RS resource overhead is independent of the SSB, and the CSSF of the CSI-RS is also independent of the CSSF of the SSB. The measurement requirements of CSI-RS and SSB (such as CSSF) can be determined respectively according to the processing method (per RS ​​method) in the above-mentioned method 3-1.

[0135] ● If the searcher capability for CSI-RS and SSB measurements is shared, that is, the measurement capability and resource overhead of CSI-RS are shared with SSB, the measurement searcher capability of the multi-carrier capability supported by the UE is configured in a per UE manner, where:

[0136] One way is to implement or declare the searcher capability (e.g. M CSI-RS , is the number of searchers used for CSI-RS measurement, M CSI-RS ≤M) to determine the CSSF for CSI-RS (or SSB) measurement.

[0137] Another way is that if CSI-RS and SSB are configured in the same neighboring cell in the same window, the CSSF is determined in the same way as the CSSF when only CSI-RS or SSB is measured separately;

[0138] Another way is that if the CSI-RS and SSB are configured in different neighboring cells, the corresponding CSSF is lengthened by multiples according to the number Z of neighboring cells to be measured, such as multiplying CSSF by Z.

[0139] Method 4: Within the measurement gap (depending on the number of measurement objects, generally one MO corresponds to one SSB or CSI-RS) Frequency measurement)

[0140] III. Mode 4-1: When the UE performs only CSI-RS or SSB measurement within the gap, the measurement requirements (such as CSSF) of the CSI-RS measurement or SSB measurement are determined according to the measurement searcher capabilities of the multi-carrier capabilities supported by the UE.

[0141] For example, in the existing SSB measurement requirements, the CSSF is obtained according to the number of measurement objects MO, and on this basis, the number of searchers supporting simultaneous measurement is eliminated.

[0142] For another example, if no new measurement searcher capability is defined or the measurement searcher capability is 2, the measurement requirement of CSI-RS is the same as the existing measurement requirement of SSB.

[0143] IV. Mode 4-2: When the UE performs CSI-RS and SSB measurements simultaneously within the gap, the measurement requirements (such as CSSF) for CSI-RS measurement or SSB measurement are determined based on the capabilities of the measurement searcher of the multi-carrier capability supported by the UE.

[0144] Similar to method 3-2, the CSSF for CSI-RS measurement or SSB measurement is determined separately according to whether the searcher capability for CSI-RS measurement and SSB measurement is shared, or whether the measurement searcher capability (M) of the multi-carrier measurement capability supported by the UE is configured per RS ​​or per UE.

[0145] For UE supporting carrier aggregation, methods 3 and 4 of the embodiments of the present application can shorten the carrier-level measurement time when multiple neighboring cell measurements are implemented by expanding the UE's ability to support simultaneous measurement of multiple carriers or frequencies, which can be achieved by reducing the CSSF.
