[0028] Figure 1 A network environment 100 according to some embodiments is shown. The network environment 100 may include a UE 104 and an access node (or "base station") 108. The access node 108 may provide one or more wireless serving cells 112 and 114, such as 3GPP New Radio "NR" cells, through which the UE 104 may communicate with the access node 108 (e.g., via an NR-Uu interface).

[0029] UE 104 may include enhanced multiple-input multiple-output (eMIMO) capabilities that support simultaneous communication via beams from several (or even many) different serving cells. Figure 1 An example of carrier aggregation (CA) is shown where UE 104 receives data from access node 108 while simultaneously receiving data from serving cell 112 over component carrier (CC) 122 and from serving cell 114 over component carrier (CC) 124 .

[0030] CC 122 may be in a frequency band that is in frequency range 1 (FR1) or frequency range 2 (FR2). Similarly, CC 124 may be in a frequency band that is in frequency range 1 (FR1) or frequency range 2 (FR2). CCs 112 and 124 may be in the same frequency band (intra-band, which may be contiguous or non-contiguous), or may be in different frequency bands (inter-band) and in potentially different frequency ranges. For FR1 (e.g., below 7.225 GHz), the transmit antenna of UE 104 is typically implemented as an omnidirectional antenna. For FR2 (e.g., 24.250 GHz and above, which is also referred to as mmWave), the transmit antenna of UE 104 may be implemented as a panel having multiple antenna elements. For example, the multiple antenna elements of the panel may be driven as a phased array (e.g., to steer a beam in a desired direction).

[0031] For effective beam management, the UE 104 may apply radio link monitoring to the serving cell, which may include beam failure detection (BFD) and / or candidate beam detection (CBD). The UE 104 may be configured to monitor the quality of each beam by comparing the signal quality of each beam to a threshold corresponding to a physical downlink control channel (PDCCH) block error rate (BLER) of 10%. If BFD indicates beam failure for all configured beams (e.g., the signal quality drops below a threshold for all beams), the UE 104 may perform CBD. During CBD, the UE 104 identifies one or more candidate beams whose signal strength is above a certain configurable threshold and reports the result (e.g., beam identification) to the serving cell. Requirements for BFD and CBD can be found, for example, in the Third Generation Partnership Project (3GPP) Technical Specification (TS) 38.133 (3GPP TS 38.133 V16.5.0 (2020-09)), entitled “3rd Generation Partnership Project; Technical Specification Group Radio Access Network; NR; Requirements for support of Radio Resource Management (Release 16)” (3GPP, Valbonne, FR) (“TS 38.133”). For example, the evaluation period for BFD and CBD may be extended for beams in FR2. Multiple CCs in a single frequency band may be expected to experience the same channel conditions (e.g., a common beam), so for intra-band CA, the UE 104 may be configured to perform BFD or CBD on only one of the CCs in the frequency band.

[0032] In some embodiments, the UE 104 may include multiple searchers capable of independently and simultaneously measuring corresponding multiple component carriers. The searchers may include baseband processing resources that can be used for beam measurement operations. Such measurement resources may include one or more of memory (e.g., buffer space), demodulation processing, and correlation processing. In some embodiments, the UE 104 may include two searchers.

[0033] Several agreements have been reached on sharing coefficients in certain multi-band CA use cases:

[0034] 1) For FR1 inter-band CA, the sharing factor is proportional to the number of bands on which the UE is performing BFD / CBD only on SCells, and no scaling factor is introduced for BFD / CBD measurements on PCell / PSCell;

[0035] 2) For FR2 inter-band CA, the sharing factor is proportional to the number of bands on which the UE is performing BFD / CBD only for SCells, and the UE is required to perform BFD / CBD only in one band among a set of bands that the UE can receive with a common beam;

[0036] 3) For FR1+FR2 CA, the sharing coefficient is the sum of the sharing coefficient of FR1 and the sharing coefficient of FR2.

[0037] These protocols are incorporated into the P BFD and P CBD in the expression.

[0038] Figure 2 1 shows a network environment 200 according to some embodiments. The network environment 100 may include a UE 104 and two or more access nodes (or "base stations") 208 and 210. Each of the access nodes 208 and 210 may provide one or more wireless serving cells, such as 3GPP New Radio "NR" cells, through which the UE 104 may communicate with the access nodes 208 and 210. In this example, the access node 208 provides two serving cells 212 and 214 for communicating with the UE 104 via CCs 222 and 224, respectively, and the access node 210 provides two serving cells 216 and 218 for communicating with the UE 104 via CCs 226 and 228, respectively.

[0039] UE 104 can communicate with access nodes 208 and 210 over an air interface that is compatible with 3GPP technical specifications, such as those defining fifth generation (5G) NR system standards. Each of access nodes 208 and 210 can be a next generation radio access network (NG-RAN) node coupled to a 5G core network. The NG-RAN node can be a gNB that provides NR user plane and control plane protocol termination to UE 104, or an ng-eNB that provides Evolved Universal Terrestrial Radio Access (E-UTRA) user plane and control plane protocol termination to UE 104.

[0040] Figure 2An example of dual connectivity (DC) is shown, in which the UE 104 can simultaneously transmit and receive data over multiple component carriers (CCs) from two different cell groups. In this example, the access node 208 is a primary node that provides a control plane connection to the core network, and the access node 210 is a secondary node. The primary node can be coupled to the 5G core (5GC) network via a backhaul connection that can support the NG-C interface. The service cells provided by the primary node (access node 208 in this example) include a primary cell group (MCG) 220, and the service cells provided by the secondary node (access node 210 in this example) include a secondary cell group (SCG) 221. Each of the MCG 220 and the SCG 221 has a primary service cell and optionally one or more secondary service cells. The primary service cell (also called a special cell or spCell) of the MCG 220 can be referred to as a PCell, and the secondary service cell of the MCG 221 can be referred to as an SCell. The primary serving cell (spCell) of the SCG 220 may be referred to as a PSCell, and the secondary serving cell of the SCG 221 may be referred to as an SCell or an SSCell. Figure 2 , serving cell 212 is a PCell, serving cell 216 is a PSCell, and serving cells 214 and 218 are SCells. Unless otherwise specified, the term "primary serving cell" may refer to either a PCell or a PSCell; unless otherwise specified, the term "secondary serving cell" may refer to either a secondary serving cell of an MCG or a secondary serving cell of an SCG; and unless otherwise specified, the term "SCell" may also refer to either a secondary serving cell of an MCG or a secondary serving cell of an SCG.

[0041] As noted above, for beams in FR2, the evaluation period of BFD and CBD can be extended. This extension can be determined by the evaluation period extension factor P as described in TS 38.133. BFD and P CBD These evaluation period extension factors can be used by the UE to allocate measurement resources for the searcher.

[0042] Dual connectivity of a UE to two NR cell groups (e.g., as provided by a primary gNB and a secondary gNB) is referred to as NR-DC. For example, NR-DC may be required in situations where the backhaul connection between the primary access node 208 and the secondary access node 210 is not optimal (e.g., the primary access node 208 and the secondary access node 210 are manufactured by different entities such that they do not share a proprietary interface that could be optimized). In the case of NR-DC, the UE 104 may apply radio link monitoring to the serving cell, which may include beam failure detection (BFD) and / or candidate beam detection (CBD). Unfortunately, the coefficient P as described in TS 38.133 BFD and PCBD The value of may provide incorrect results for some NR-DC cases, such as FR1+FR2 NR-DC, where the UE 104 is also configured for inter-band CA in FR2 (e.g., in an SCG). For example, examples of such new band combinations are specified in Parts 1, 2, and 3 of 3GPP Technical Specification (TS) 38.101 (3GPP TS38.101-1 / 2 / 3 V16.5.0 (2020-09)) ("TS 38.101"). For example, Table 5.5B.7.2 of Part 3 of TS 38.101 specifies several new band combinations, each of which includes two bands from FR1 and a third band from FR2. In such cases, the UE 104 may be configured to perform CBD or BFD on the PCell, PSCell, and one or more SCells on different bands. The coefficient P as described in TS 38.133 BFD and P CBD The values ​​of cannot be used for searcher resource allocation in such cases because they are not suitable for the situation where both PCell and PSCell compete for searcher resources. BFD and P CBD The value of may also not be suitable for mixed situations where BFD is configured on one or more frequency bands and CBD is configured on one or more other frequency bands.

[0043] Figure 3 An operational flow / algorithm structure 300 according to some embodiments is illustrated. The operational flow / algorithm structure 300 may be performed or implemented by a UE (such as, for example, UE 104 or UE 1000) or a component thereof (eg, baseband processor 1004A).

[0044] The operation process / algorithm structure 300 may include: at 304, receiving a first configuration of a first beam management operation including beam failure detection (BFD) or candidate beam detection (CBD) for a primary serving cell (PCell). The operation process / algorithm structure 300 may include: at 308, receiving a second configuration of a second beam management operation including BFD or CBD for a primary secondary cell (PSCell). The operation process / algorithm structure 300 may include: at 312, receiving a third configuration of a third beam management operation including BFD or CBD for a secondary serving cell (SCell). The first configuration, the second configuration, and the third configuration may configure one or more reference signals to be used as beam management reference signals. The reference signals may include SSB or CSI-RS resources, which may be indicated according to resource elements (wherein a resource element is a subcomponent consisting of a subcarrier in the frequency domain and a symbol interval in the time domain). The set of reference signals may be configured for serving cells. The CSI-RS resources are identified in the set and can be configured for the serving cell. Identifies SSB resources.

[0045] The configuration may include UE-specific or cell-specific configuration information.

[0046] The operation flow / algorithm structure 300 may include: at 316, calculating a first evaluation period extension coefficient based on the first configuration, the second configuration, and the third configuration (e.g., setting a value thereof). In the example of extending the CBD evaluation period based on SSB, at 316, the first evaluation period extension coefficient P may be calculated for PCell. CBD The second evaluation period extension coefficient P for PSCell can also be calculated according to the number of frequency bands on which BFD is configured. CBD The value of and the value of the third evaluation period extension factor for any SCell. In one such example (as discussed in Option 2 of the third example below):

[0047] 1) For the set configured for PCell Each synchronization signal block (SSB) resource in the SyncSignalBlock and for the set configured for the PSCell Each synchronization signal block (SSB) in

[0048] Resources, P CBD =2;

[0049] 2) For the set configured for SCell Each SSB resource in P CBD is the number of frequency bands on which the UE is performing CBD only for SCells.

[0050] Figure 11 An operational flow / algorithm structure 1100 according to some embodiments is shown. The operational flow / algorithm structure 1100 may be performed or implemented by a UE (such as, for example, UE 104 or UE 1000) or a component thereof (eg, baseband processor 1004A).

[0051] The operational flow / algorithm structure 1100 may include operations 304, 308, 312, and 316 as described herein. The operational flow / algorithm structure 1100 may also include, at 1112, instructing to allocate searcher measurement resources between the PCell and the PSCell based on the calculated first evaluation period extension factor. Allocating the searcher measurement resources includes allocating a portion (possibly all) of the first searcher to the PCell.

[0052] Operational flow / algorithm structure 1100 may also include, at 1116, performing a first beam management operation based on the assignment. The first beam management operation may be BFD or CBD as described herein. In some embodiments, UE 104 may measure CBD RSs, such as those transmitted by multiple candidate beams. In these or other embodiments, UE 104 may measure BFD RSs, such as those transmitted by multiple candidate beams. UE 104 may select a candidate beam from the multiple candidate beams based on these measurements.

[0053] In a first example, the application of the operational flow / algorithm structure 300 and 1100 in extending the BFD evaluation period based on CSI-RS is described. In this example, the network and / or UE 104 can be configured with a minimum assumption: in the case of multiple CCs in a single frequency band, BFD is performed on only one CC in the frequency band.

[0054] If only one of the PCell and PSCell has been configured with BFD, then at 316, for the set configured for PCell or PSCell Each CSI-RS resource in P BFD The value of can be set to one, and for the set configured for SCell Each CSI-RS resource in P BFD The value of may be set equal to the number of frequency bands on which the UE 104 is performing BFD for the SCell.

[0055] However, if both the PCell and PSCell have been configured with BFD, then at 316, for the set configured for the PCell or PSCell Each CSI-RS resource in P BFD The value of can be set according to one of the following three options:

[0056] In the first option (Option 1), for PCell, P BFD The value of can be set equal to one, and for PSCell, P BFD The value of may be set equal to one more than the number of bands on which the UE 104 is performing BFD for the SCell (e.g., the number of bands on which the UE 104 is performing BFD for the SCell plus one). Each CSI-RS resource in P BFD The value of P may also be set equal to one more than the number of frequency bands on which the UE 104 is performing BFD for the SCell. BFD These values ​​are in Figure 4 The first row ("Option 1") of the table is shown.

[0057] If option 1 is used, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and another measurement resource or searcher is also indicated to be allocated for sharing between the PSCell and the SCell for which the UE 104 is performing BFD. This allocation scheme, as applied to two searchers (searcher A and searcher B), is shown in FIG. Figure 5 The first row ("Option 1") of the table is shown.

[0058] In the second option (Option 2), for PCell, P BFD The value of can be set equal to two, and for PSCell, P BFD The value of can also be set to equal to 2. For the set configured for SCell Each CSI-RS resource in P BFD The value of P may be set equal to the number of frequency bands on which the UE 104 is performing BFD for the SCell. BFD These values ​​are in Figure 4 If option 2 is adopted, then at 1112, it is indicated that measurement resources or searchers are allocated between PCell and PSCell for sharing. Figure 5 The second row ("Option 2") of the table is shown.

[0059] In the third option (Option 3), for PCell, P BFD The value of can be set equal to one, and for PSCell, P BFD The value of can be set to equal 2. For the set configured for SCell Each CSI-RS resource in P BFD The value of P may be set equal to twice the number of frequency bands on which the UE 104 is performing BFD for the SCell. BFD These values ​​are in Figure 4 If option 3 is adopted, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and a portion (e.g., 50 percent or 1 / 2) of another measurement resource or searcher is indicated to be allocated to the PSCell. This allocation scheme is shown in the third row ("Option 3") of the table. Figure 5 is shown in the third row ("Option 3") of the table.

[0060] In a second example, the application of the operational flow / algorithm structure 300 and 1100 in extending the CSI-RS based CBD evaluation period is described. In this example, the network and / or UE 104 can be configured with a minimum assumption: in the case of multiple CCs in a single frequency band, CBD is performed only for one CC in the frequency band.

[0061] If only one of the PCell and PSCell has been configured with a CBD, then at 316, for the set configured for the PCell or PSCell, Each CSI-RS resource in P CBD The value of can be set to one, and for the set configured for SCell Each CSI-RS resource in P CBD The value of may be set equal to the number of frequency bands on which the UE 104 is performing CBD for the SCell.

[0062] However, if both the PCell and the PSCell have been configured with CBD, then at 316, for the set configured for the PCell or PSCell Each CSI-RS resource in P CBD The value of can be set according to one of the following three options:

[0063] In the first option (Option 1), for PCell, P CBD The value of can be set equal to one, and for PSCell, P CBD The value of may be set equal to one more than the number of bands on which the UE 104 is performing CBD for the SCell (e.g., the number of bands on which the UE 104 is performing BFD for the SCell plus one). Each CSI-RS resource in P CBD The value of may also be set equal to one more than the number of frequency bands on which the UE 104 is performing CBD on the SCell. CBD These values ​​are in Figure 6 The first row ("Option 1") of the table is shown.

[0064] If option 1 is used, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and another measurement resource or searcher is also indicated to be allocated for sharing between the PSCell and the SCell for which the UE 104 is performing CBD. This allocation scheme, as applied to two searchers (searcher A and searcher B), is shown in FIG. Figure 5 The first row ("Option 1") of the table is shown.

[0065] In the second option (Option 2), for PCell, P CBD The value of can be set equal to two, and for PSCell, P CBD The value of can also be set to equal to 2. For the set configured for SCell Each CSI-RS resource in PCBD The value of may be set equal to the number of frequency bands on which the UE 104 is performing CBD on the SCell. CBD These values ​​are in Figure 6 If option 2 is adopted, then at 1112, it is indicated that measurement resources or searchers are allocated between PCell and PSCell for sharing. Figure 5 The second row ("Option 2") of the table is shown.

[0066] In the third option (Option 3), for PCell, P CBD The value of can be set equal to one, and for PSCell, P CBD The value of can be set to equal 2. For the set configured for SCell Each CSI-RS resource in P CBD The value of may be set equal to twice the number of frequency bands on which the UE 104 is performing CBD for the SCell. CBD These values ​​are in Figure 6 If option 3 is adopted, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and a portion (e.g., 50 percent or 1 / 2) of another measurement resource or searcher is indicated to be allocated to the PSCell. This allocation scheme is shown in the third row ("Option 3") of the table. Figure 5 is shown in the third row ("Option 3") of the table.

[0067] In a third example, the application of the operational flow / algorithm structure 300 and 1100 in an extended enhancement of the CBD evaluation period based on SSB is described. In this example, the network and / or UE 104 can be configured with a minimum assumption: in the case of multiple CCs in a single frequency band, CBD is performed only for one CC in the frequency band.

[0068] If only one of the PCell and PSCell has been configured with a CBD, then at 316, for the set configured for the PCell or PSCell, Each SSB resource in P CBD The value of can be set to one, and for the set configured for SCell Each SSB resource in P CBD The value of may be set equal to the number of frequency bands on which the UE 104 is performing CBD for the SCell.

[0069] However, if both the PCell and the PSCell have been configured with CBD, then at 316, for the set configured for the PCell or PSCell Each SSB resource in P CBD The value of can be set according to one of the following three options:

[0070] In the first option (Option 1), for PCell, P CBD The value of can be set equal to one, and for PSCell, P CBD The value of may be set equal to one more than the number of bands on which the UE 104 is performing CBD for the SCell (e.g., the number of bands on which the UE 104 is performing BFD for the SCell plus one). Each SSB resource in P CBD The value of may also be set equal to one more than the number of frequency bands on which the UE 104 is performing CBD on the SCell. CBD These values ​​are in Figure 6 The first row ("Option 1") of the table is shown.

[0071] If option 1 is used, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and another measurement resource or searcher is also indicated to be allocated for sharing between the PSCell and the SCell for which the UE 104 is performing CBD. This allocation scheme, as applied to two searchers (searcher A and searcher B), is shown in FIG. Figure 5 The first row ("Option 1") of the table is shown.

[0072] In the second option (Option 2), for PCell, P CBD The value of can be set equal to two, and for PSCell, P CBD The value of can also be set to equal to 2. For the set configured for SCell Each SSB resource in P CBD The value of may be set equal to the number of frequency bands on which the UE 104 is performing CBD on the SCell. CBD These values ​​are in Figure 6 If option 2 is adopted, then at 1112, it is indicated that measurement resources or searchers are allocated between PCell and PSCell for sharing. Figure 5 The second row ("Option 2") of the table is shown.

[0073] In the third option (Option 3), for PCell, P CBD The value of can be set equal to one, and for PSCell, P CBD The value of can be set to equal 2. For the set configured for SCell Each SSB resource in PCBD The value of may be set equal to twice the number of frequency bands on which the UE 104 is performing CBD for the SCell. CBD These values ​​are in Figure 6 If option 3 is adopted, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and a portion (e.g., 50 percent or 1 / 2) of another measurement resource or searcher is indicated to be allocated to the PSCell. This allocation scheme is shown in the third row ("Option 3") of the table. Figure 5 is shown in the third row ("Option 3") of the table.

[0074] In the fourth example, another application of the operation flow / algorithm structure 300 and 1100 in the enhancement of the BFD evaluation period extension based on CSI-RS is described. In this example, the network and / or UE 104 can be configured with the minimum assumption that, in the case of multiple CCs in a single frequency band, only one of BFD and CBD is performed on the frequency band, and only one of the CCs in the frequency band is performed with BFD or CBD. In this example, the network and / or UE 104 can be configured not to assume that BFD and CBD operate together in the same frequency band in any particular period. In other words, the network and / or UE 104 can be configured to assume that BFD or CBD (but not both) operates in the frequency band configured for BFD or CBD.

[0075] If only one of the PCell and PSCell has been configured with BFD or CBD (i.e., one has been configured with BFD or CBD and the other has not been configured with BFD and has not been configured with CBD), then at 316, for the set configured for the PCell or PSCell, Each CSI-RS resource in P BFD The value of can be set to one, and for the set configured for SCell Each CSI-RS resource in P BFD The value of may be set equal to the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell.

[0076] However, if the PCell is configured with BFD or CBD and the PSCell is configured with BFD or CBD (i.e., both are configured with BFD, both are configured with CBD, or one is configured with BFD and the other is configured with CBD), then at 316, for the set configured for the PCell or PSCell, Each CSI-RS resource in P BFD The value of can be set according to one of the following three options:

[0077] In the first option (Option 1), for PCell, P BFD The value of can be set equal to one, and for PSCell, P BFD The value of may be set equal to one more than the number of bands on which the UE 104 is performing BFD or CBD on the SCell (e.g., the number of bands on which the UE 104 is performing BFD on the SCell plus the number of bands on which the UE 104 is performing CBD on the SCell plus one). Each CSI-RS resource in P BFD The value of may also be set equal to one more than the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. BFD These values ​​are in Figure 7 The first row ("Option 1") of the table is shown.

[0078] If option 1 is used, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and another measurement resource or searcher is also indicated to be allocated for sharing between the PSCell and the SCell on which the UE 104 is performing BFD or CBD. This allocation scheme, as applied to two searchers (searcher A and searcher B), is shown in FIG. Figure 5 The first row ("Option 1") of the table is shown.

[0079] In the second option (Option 2), for PCell, P BFD The value of can be set equal to two, and for PSCell, P BFD The value of can also be set to equal to 2. For the set configured for SCell Each CSI-RS resource in P BFD The value of P may be set equal to the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. BFD These values ​​are in Figure 7 If option 2 is adopted, then at 1112, it is indicated that measurement resources or searchers are allocated between PCell and PSCell for sharing. Figure 5 The second row ("Option 2") of the table is shown.

[0080] In the third option (Option 3), for PCell, P BFD The value of can be set equal to one, and for PSCell, P BFD The value of can be set to equal 2. For the set configured for SCell Each CSI-RS resource in P BFDThe value of P may be set equal to twice the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. BFD These values ​​are in Figure 7 If option 3 is adopted, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and a portion (e.g., 50 percent or 1 / 2) of another measurement resource or searcher is indicated to be allocated to the PSCell. This allocation scheme is shown in the third row ("Option 3") of the table. Figure 5 is shown in the third row ("Option 3") of the table.

[0081] In the fifth example, another application of the operational flow / algorithm structure 300 and 1100 to an extended enhancement of the CSI-RS-based or SSB-based CBD evaluation period is described. In this example, the network and / or UE 104 can be configured with minimal assumptions: in the case of multiple CCs in a single frequency band, only one of BFD and CBD is performed on the frequency band, and only one of the CCs in the frequency band is performed BFD or CBD. In this example, the network and / or UE 104 can be configured not to assume that BFD and CBD operate together in the same frequency band in any particular period. In other words, the network and / or UE 104 can be configured to assume that BFD or CBD (but not both) operates in the frequency band configured for BFD or CBD.

[0082] If only one of the PCell and PSCell has been configured with BFD or CBD (i.e., one has been configured with BFD or CBD and the other has not been configured with BFD and has not been configured with CBD), then at 316, for the set configured for the PCell or PSCell, For each CSI-RS or SSB resource in P CBD The value of can be set to one, and for the set configured for SCell For each CSI-RS or SSB resource in P CBD The value of may be set equal to the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell.

[0083] However, if the PCell is configured with BFD or CBD and the PSCell is configured with BFD or CBD (i.e., both are configured with BFD, both are configured with CBD, or one is configured with BFD and the other is configured with CBD), then at 316, for the set configured for the PCell or PSCell, For each CSI-RS or SSB resource in P CBD The value of can be set according to one of the following three options:

[0084] In the first option (Option 1), for PCell, P CBD The value of can be set equal to one, and for PSCell, P CBD The value of may be set equal to one more than the number of bands on which the UE 104 is performing BFD or CBD on the SCell (e.g., the number of bands on which the UE 104 is performing BFD on the SCell plus the number of bands on which the UE 104 is performing CBD on the SCell plus one). For each CSI-RS or SSB resource in P CBD The value of may also be set equal to one more than the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. CBD These values ​​are in Figure 8 The first row ("Option 1") of the table is shown.

[0085] If option 1 is used, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and another measurement resource or searcher is also indicated to be allocated for sharing between the PSCell and the SCell on which the UE 104 is performing BFD or CBD. This allocation scheme, as applied to two searchers (searcher A and searcher B), is shown in FIG. Figure 5 The first row ("Option 1") of the table is shown.

[0086] In the second option (Option 2), for PCell, P CBD The value of can be set equal to two, and for PSCell, P CBD The value of can also be set to equal to 2. For the set configured for SCell For each CSI-RS or SSB resource in P CBD The value of P may be set equal to the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. CBD These values ​​are in Figure 8 If option 2 is adopted, then at 1112, it is indicated that measurement resources or searchers are allocated between PCell and PSCell for sharing. Figure 5 The second row ("Option 2") of the table is shown.

[0087] In the third option (Option 3), for PCell, P CBD The value of can be set equal to one, and for PSCell, P CBD The value of can be set to equal 2. For the set configured for SCell For each CSI-RS or SSB resource in PCBD The value of P may be set equal to twice the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. CBD These values ​​are in Figure 8 If option 3 is adopted, then at 1112, a dedicated measurement resource or searcher is indicated to be allocated to the PCell, and a portion (e.g., 50 percent or 1 / 2) of another measurement resource or searcher is indicated to be allocated to the PSCell. This allocation scheme is shown in the third row ("Option 3") of the table. Figure 5 is shown in the third row ("Option 3") of the table.

[0088] Figure 12 An operational flow / algorithm structure 1200 according to some embodiments is shown. The operational flow / algorithm structure 1200 may be performed or implemented by a UE (such as, for example, UE 104 or UE 1000) or a component thereof (eg, baseband processor 1004A).

[0089] The operational flow / algorithm structure 1200 may include operations 304, 308, 312, 316, 1112, and 1116 as described herein. The operational flow / algorithm structure 1200 may also include determining an evaluation period for the first beam management operation based on the calculated first evaluation period extension factor at 1208. For example, if the first beam management operation is CSI-RS-based BFD, the UE 104 may determine the evaluation period based on the expression defined in Tables 8.5.3.2-1 (for FR1) and 8.5.3.2-2 (for FR2) of TS 38.133, which corresponds to the configured frequency range and DRX cycle for the first beam management operation. For example, if the first beam management operation is CBD based on CSI-RS, the UE 104 may determine an evaluation period based on the expression defined in Table 8.5.6.2-1 (for FR1) and Table 8.5.6.2-2 (for FR2) of TS 38.133, which corresponds to the configured frequency range and DRX cycle for the first beam management operation. For example, if the first beam management operation is CBD based on SSB, the UE 104 may determine an evaluation period based on the expression defined in Table 8.5.5.2-1 (for FR1) and Table 8.5.5.2-2 (for FR2) of TS 38.133, which corresponds to the configured frequency range and DRX cycle for the first beam management operation. The UE 104 may use this evaluation period determination to configure its measurement behavior. For example, by determining this evaluation period, the UE 104 may know how many samples (e.g., samples of resources such as CSI-RS or SSB) it can use for evaluation and how many beams it can scan within the evaluation period.

[0090] For example, for SSB-based candidate beam detection, the operational flow / algorithm structure 300 may calculate the evaluation period T for frequency range 1 (FR1) as described in Table 8.5.5.2-1 of TS 38.133 at 308. 评估_CBD_SSB (in milliseconds (ms)), as follows (where T SSB is the period of the SSB in the set, and T DRX is the discontinuous reception (DRX) cycle length):

[0091] 1) For non-DRX configurations and configurations where the DRX cycle is no longer than 320ms,

[0092] T 评估_CBD_SSB =max(25,ceil(3×P×P CBD )×T SSB ).

[0093] 2) For configurations with a DRX cycle greater than 320ms,

[0094] T 评估_CBD_SSB =ceil(3×P×P CBD )×T DRX ),

[0095] where the value of parameter P is as described in section 8.5.5.2 of TS 38.133 (eg, has a value of one when the measurement gap does not overlap with any instance of an SSB in the monitored cell, and is otherwise based on the measurement gap repetition period).

[0096] Figure 9 A receiving component 900 of a device according to some embodiments is shown. The device may be a UE 104 or a serving cell 112, 114, 212, 214, 216, or 218.

For example, the analog BF component 912 can be coupled to one or more RF chains 920, and the analog BF component 916 can be coupled to one or more RF chains 924. The RF chain can amplify the received analog RF signal, down-convert the RF signal to baseband, and convert the analog baseband signal into a digital baseband signal that can be provided to the digital BF component 928. The digital BF component 928 can provide the baseband (BB signal) for further BB processing.

[0099] In various embodiments, control circuitry, which may reside in a baseband processor, may provide BF weights to the analog / digital BF components to provide receive beams at corresponding antenna panels. These BF weights may be determined by the control circuitry based on a received reference signal and corresponding QCL / TCI information as described herein. In some embodiments, the BF weights may be phase shift values ​​provided to the phase shifters of the analog BF components 912 or complex weights provided to the digital BF components 928. In some embodiments, the BF components and antenna panels may operate together to provide a dynamic phased array capable of steering a beam in a desired direction.

[0100] In various embodiments, beamforming may include analog beamforming, purely digital beamforming, or hybrid analog and digital beamforming.Digital beamforming may utilize separate RF chains corresponding to respective antenna elements.
