[0028] Figure 1 A network environment 100 is shown in accordance with some embodiments. 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 service 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 the NR-Uu interface).

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

[0030] CC 122 can be in a frequency band that is in Frequency Range 1 (FR1) or Frequency Range 2 (FR2). Similarly, CC 124 can be in a frequency band that is in Frequency Range 1 (FR1) or Frequency Range 2 (FR2). CC 112 and 124 can be in the same frequency band (intra-band, either contiguous or non-contiguous), or can 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 can be implemented as a panel with multiple antenna elements. For example, the multiple antenna elements of the panel can be driven as a phased array (e.g., to steer a beam in a desired direction).

[0031] For effective beam management, UE 104 can apply radio link monitoring to the serving cell, which can include beam failure detection (BFD) and / or candidate beam detection (CBD). UE 104 can be configured to monitor the quality of each beam by comparing the signal quality of each beam with a threshold corresponding to a 10% physical downlink control channel (PDCCH) block error rate (BLER). If BFD indicates beam failure for all configured beams (e.g., for all beams, the signal quality drops below the threshold), then UE 104 can perform CBD. During CBD, UE 104 identifies one or more candidate beams whose signal strength is higher than a configurable threshold and reports the results (e.g., beam identities) to the serving cell. Requirements for BFD and CBD can be found, for example, in the 3rd Generation Partnership Project (3GPP) Technical Specification (TS) 38.133, "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, for beams in FR2, the evaluation periods for BFD and CBD can be extended. It is expected that multiple CCs in a single frequency band experience the same channel conditions (e.g., common beams), so for intra-band CA, UE 104 can be configured to perform BFD or CBD on only one of the CCs in the frequency band.

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

[0033] Some agreements have been reached on the sharing factor 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 for SCell, and no scaling factor is introduced for BFD / CBD measurements on the 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 SCell, and the UE is required to perform BFD / CBD only in one of a set of bands that can be received by the common beam available to the UE;

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

[0037] These agreements are incorporated into the expressions of P BFD and P CBD defined in Section 8.5 of TS 38.133.

[0038] Figure 2 FIG. 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 radio service cells through which the UE 104 can communicate with the access nodes 208 and 210, e.g., 3GPP New Radio "NR" cells. In this example, the access node 208 provides two service cells 212 and 214 that communicate with the UE 104 through CCs 222 and 224, respectively, and the access node 210 provides two service cells 216 and 218 that communicate with the UE 104 through CCs 226 and 228, respectively.

[0039] The UE 104 may communicate with the access nodes 208 and 210 through an air interface compatible with 3GPP technical specifications such as those that define the standards for the fifth generation (5G) NR system. Each of the access nodes 208 and 210 may be a next-generation radio access network (NG-RAN) node coupled to a 5G core network. The NG-RAN node may be a gNB that provides NR user plane and control plane protocol termination to the UE 104, or an ng-eNB that provides evolved universal terrestrial radio access (E-UTRA) user plane and control plane protocol termination to the UE 104.

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

[0041] As pointed out above, for beams in FR2, the evaluation periods of BFD and CBD can be extended. This extension can be indicated by the evaluation period extension factors P BFD and P CBD which can be used by the UE to allocate measurement resources for the searcher.

[0042] The dual connectivity of the UE with two NR cell groups (e.g., as provided by the master gNB and the secondary gNB) is referred to as NR-DC. For example, NR-DC may be required when the backhaul connection between the master access node 208 and the secondary access node 210 is not optimal (e.g., the master 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 terms of NR-DC, the UE 104 can apply radio link monitoring to the serving cells, which can include beam failure detection (BFD) and / or candidate beam detection (CBD). Unfortunately, as described in TS 38.133, the coefficients P BFD and PCBD The value provides incorrect results for some NR-DC scenarios, such as FR1+FR2 NR-DC where the UE 104 is also configured for inter-band CA in FR2 (e.g., in the SCG). For example, examples of such new frequency band combinations are specified in parts 1, 2, and 3 of the 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 in part 3 of TS 38.101 specifies several new frequency band combinations, each including two frequency bands from FR1 and a third frequency 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 SCell on different frequency bands. Coefficients P BFD and P CBD values cannot be used for searcher resource allocation in such cases because they are not suitable for the scenario where both the PCell and PSCell compete for searcher resources. Additionally, coefficients P BFD and P CBD values may also not be suitable for hybrid cases where BFD is configured on one or more frequency bands and CBD is configured on one or more other frequency bands.

[0043] Figure 3 Illustrates an operational flow / algorithm structure 300 according to some embodiments. The operational flow / algorithm structure 300 may be executed or implemented by a UE (such as, for example, UE 104 or UE 1000) or its components (such as baseband processor 1004A).

[0044] The operational flow / algorithm structure 300 may include: at 304, receiving a first configuration for a primary serving cell (PCell) of a first beam management operation including beam failure detection (BFD) or candidate beam detection (CBD). The operational flow / algorithm structure 300 may include, at 308, receiving a second configuration for a primary secondary cell (PSCell) of a second beam management operation including BFD or CBD. The operational flow / algorithm structure 300 may include: at 312, receiving a third configuration for a secondary serving cell (SCell) of a third beam management operation including BFD or CBD. The first configuration, second configuration, and 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 (where a resource element is a sub-component composed of a sub-carrier in the frequency domain and a symbol interval in the time domain). May be in a set configured for serving cells Identify CSI-RS resources therein and may identify SSB resources in the set configured for the serving cell Identify SSB resources therein.

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

[0046] The operation flow / algorithm structure 300 may include: at 316, calculate a first evaluation period extension factor based on the first configuration, the second configuration, and the third configuration (e.g., set its value). In an example of enhanced extension of the SSB-based CBD evaluation period, at 316, the first evaluation period extension factor P CBD value for the PCell may be calculated, and the second evaluation period extension factor P CBD value for the PSCell and the third evaluation period extension factor value for any SCell may also be calculated according to the number of bands on which BFD is configured. In one such example (as discussed in option 2 of the following third example):

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

[0048] resource, P CBD = 2;

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

[0050] Figure 11 Illustrates an operation flow / algorithm structure 1100 according to some embodiments. The operation flow / algorithm structure 1100 may be executed or implemented by a UE (such as, for example, UE 104 or UE 1000) or its components (e.g., baseband processor 1004A).

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

[0052] The operation procedure / algorithm structure 1100 may further include: at 1116, performing a first beam management operation according to the allocation. The first beam management operation may be BFD or CBD as described herein. In some embodiments, the UE 104 may measure the CBD RS transmitted by multiple candidate beams. In these or other embodiments, the UE 104 may measure the BFD RS transmitted by multiple candidate beams. The UE 104 may select one candidate beam from the multiple candidate beams based on these measurements.

[0053] In a first example, the application of the operation procedure / algorithm structures 300 and 1100 in the enhanced extension of the CSI-RS-based BFD evaluation period is described. In this example, the network and / or the UE 104 may be configured with minimal assumptions: in the case of multiple CCs in a single frequency band, BFD is performed only on one CC in that frequency band.

[0054] If only one of the PCell and the PSCell is configured with BFD, then at 316, for each CSI-RS resource in the set configured for the PCell or the PSCell, the value of P BFD may be set to be equal to one, and for each CSI-RS resource in the set configured for the SCell, the value of P BFD may be set to be 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 the PSCell are configured with BFD, then at 316, for each CSI-RS resource in the set configured for the PCell or the PSCell, the value of P BFD may be set according to one of the following three options:

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

[0057] If option 1 is adopted, at 1112, it is indicated that dedicated measurement resources or a searcher are allocated to the PCell, and it is also indicated that another measurement resource or searcher is allocated for sharing between the PSCell and the SCell on which the UE 104 performs BFD. This allocation scheme for two searchers (searcher A and searcher B) is shown in Figure 5 the first row (“option 1”) of the table in

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

[0059] In the third option (option 3), for the PCell, the value of P BFD can be set to be equal to one, and for the PSCell, the value of P BFD can be set to be equal to two. For each CSI-RS resource in the set configured for the SCell, the value of P BFD can be set to be equal to twice the number of frequency bands on which the UE 104 is performing BFD for the SCell. These values of P BFD are shown in the third row (“option 3”) of the table in Figure 4 If option 3 is adopted, at 1112, it is indicated that dedicated measurement resources or a searcher are allocated to the PCell, and it is indicated that a part (e.g., fifty percent or one half) of another measurement resource or searcher is allocated to the PSCell. This allocation scheme is shown in the third row (“option 3”) of the table in Figure 5

[0060] In the second example, the application of the operation flow / algorithm structure 300 and 1100 in the extended enhancement of the CSI-RS based CBD evaluation cycle is described. In this example, the network and / or the UE 104 can be configured with minimal assumptions: in the case of multiple CCs in a single frequency band, CBD is performed only for one CC in that frequency band.​​

[0061] If only one of the PCell and the PSCell is configured with CBD, then at 316, for each CSI-RS resource in the set configured for the PCell or the PSCell , the value of P CBD can be set equal to one, and for each CSI-RS resource in the set configured for the SCell , the value of P CBD can 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 are configured with CBD, then at 316, for each CSI-RS resource in the set configured for the PCell or the PSCell , the value of P CBD can be set according to one of the following three options:

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

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

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

[0066] In the third option (Option 3), for the PCell, the value of P CBD can be set to be equal to one, and for the PSCell, the value of P CBD can be set to be equal to two. For each CSI-RS resource in the set configured for the SCell, the value of P CBD can be set to be equal to twice the number of frequency bands on which the UE 104 is performing CBD for the SCell. CBD These values of P are shown in the third row (“Option 3”) of the table in Figure 6 . If Option 3 is adopted, at 1112, it is indicated that dedicated measurement resources or searchers are allocated to the PCell, and it is indicated that a part (e.g., fifty percent or one half) of another measurement resource or searcher is allocated to the PSCell. This allocation scheme is shown in the third row (“Option 3”) of the table in Figure 5 .

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

[0068] If only one of the PCell and the PSCell is configured with CBD, at 316, for each SSB resource in the set configured for the PCell or the PSCell, the value of P CBD can be set to be equal to one, and for each SSB resource in the set configured for the SCell, the value of P CBD can be set to be 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 are configured with CBD, at 316, for each SSB resource in the set For 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 the PCell, P CBD The value of can be set to equal one, and for the PSCell, P CBD The value of can be set to equal 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). For each SSB resource in the set configured for the SCell, P CBD The value of can also be set to equal one more than the number of bands on which the UE 104 is performing CBD for the SCell. The values of P CBD are shown in the first row (“Option 1”) of the table in Figure 6 .

[0071] If Option 1 is adopted, at 1112, it is indicated that dedicated measurement resources or searchers are allocated to the PCell, and it is also indicated that another measurement resource or searcher is allocated for sharing between the PSCell and the SCell on which the UE 104 is performing CBD. This allocation scheme for two searchers (Searcher A and Searcher B) is shown in the first row (“Option 1”) of the table in Figure 5 .

[0072] In the second option (Option 2), for the PCell, P CBD The value of can be set to equal two, and for the PSCell, P CBD The value of can also be set to equal two.

The values of P CBD are shown in the second row (“Option 2”) of the table in Figure 6 . If Option 2 is adopted, at 1112, it is indicated that measurement resources or searchers are allocated for sharing between the PCell and the PSCell.

[0074] In the fourth example, another application of the operation flow / algorithm structure 300 and 1100 in the CSI-RS-based BFD evaluation cycle extension enhancement is described. In this example, the network and / or the 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 with BFD or CBD. In this example, the network and / or the UE 104 can be configured not to assume that BFD and CBD run together in the same frequency band in any specific cycle. In other words, the network and / or the UE 104 can be configured to assume that either BFD or CBD (but not both) runs in the frequency band configured for BFD or CBD.

[0075] If only one of the PCell and the PSCell is configured with BFD or CBD (i.e., one is configured with BFD or CBD, and the other is not configured with BFD and not configured with CBD), then at 316, for each CSI-RS resource in the set configured for the PCell or the PSCell, P BFD The value can be set to be equal to one, and for each CSI-RS resource in the set configured for the SCell, P BFD The value can be set to be 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 each CSI-RS resource in the set configured for the PCell or the PSCell, P BFD The value can be set according to one of the following three options:

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

[0078] If Option 1 is adopted, at 1112, it is indicated that dedicated measurement resources or searchers are allocated to the PCell, and it is also indicated that another measurement resource or searcher is 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 the first row (“Option 1”) of the table in Figure 5 .

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

[0080] In the third option (Option 3), for the PCell, the value of P BFD can be set equal to one, and for the PSCell, the value of P BFD can be set equal to two. For each CSI-RS resource in the set configured for the SCell, the value of P BFDThe value can be set to be equal to twice the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. P BFD These values of Figure 7 are shown in the third row (“Option 3”) of the table of Figure 5 . If Option 3 is adopted, at 1112, it is indicated that dedicated measurement resources or searchers are allocated to the PCell, and it is indicated that a part (e.g., fifty percent or one half) of another measurement resource or searcher is allocated to the PSCell. This allocation scheme is shown in the third row (“Option 3”) of the table of

[0081] In the fifth example, another application of the operation flow / algorithm structure 300 and 1100 for the extended enhancement of the CSI-RS or SSB-based CBD evaluation period is described. In this example, the network and / or the 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 with BFD or CBD. In this example, the network and / or the UE 104 can be configured not to assume that BFD and CBD run together in the same frequency band in any specific period. In other words, the network and / or the UE 104 can be configured to assume that either BFD or CBD (but not both) runs in the frequency band configured for BFD or CBD.

[0082] If only one of the PCell and the PSCell is configured with BFD or CBD (i.e., one is configured with BFD or CBD, and the other is not configured with BFD and not configured with CBD), then at 316, for each CSI-RS or SSB resource in the set configured for the PCell or the PSCell, P CBD The value can be set to be equal to one, and for each CSI-RS or SSB resource in the set configured for the SCell, P CBD The value can be set to be 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 each CSI-RS or SSB resource in the set configured for the PCell or the PSCell, P CBD The value can be set according to one of the following three options:

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

[0085] If Option 1 is adopted, at 1112, it is indicated that dedicated measurement resources or searchers are allocated to the PCell, and it is also indicated that another measurement resource or searcher is 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 the first row (“Option 1”) of the table in Figure 5 .

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

[0087] In the third option (Option 3), for the PCell, the value of P CBD can be set to be equal to one, and for the PSCell, the value of P CBD can be set to be equal to two. For each CSI-RS or SSB resource in the set configured for the SCell, PCBD The value can be set to be equal to twice the number of frequency bands on which the UE 104 is performing BFD or CBD on the SCell. P CBD These values of Figure 8 are shown in the third row (“Option 3”) of the table of Figure 5 . If Option 3 is adopted, at 1112, it is indicated that dedicated measurement resources or searchers are allocated to the PCell, and it is indicated that a part (e.g., fifty percent or one half) of another measurement resource or searcher is allocated to the PSCell.

[0088] Figure 12 FIG. 1200 shows an operation flow / algorithm structure according to some embodiments. The operation flow / algorithm structure 1200 can be executed or implemented by a UE (such as, for example, UE 104 or UE 1000) or its components (such as baseband processor 1004A).

[0089] The operation flow / algorithm structure 1200 can include operations 304, 308, 312, 316, 1112, and 1116 as described herein. The operation flow / algorithm structure 1200 can further include: at 1208, determining an evaluation period for a first beam management operation based on the calculated first evaluation period extension factor. For example, for the case where the first beam management operation is CSI-RS-based BFD, the UE 104 can determine the evaluation period according to the expressions defined in Table 8.5.3.2-1 (for FR1) and 8.5.3.2-2 (for FR2) of TS 38.133, which correspond to the configured frequency range and DRX cycle for the first beam management operation. For example, for the case where the first beam management operation is CSI-RS-based CBD, the UE 104 can determine the evaluation period according to the expressions defined in Table 8.5.6.2-1 (for FR1) and 8.5.6.2-2 (for FR2) of TS 38.133, which correspond to the configured frequency range and DRX cycle for the first beam management operation. For example, for the case where the first beam management operation is SSB-based CBD, the UE 104 can determine the evaluation period according to the expressions defined in Table 8.5.5.2-1 (for FR1) and 8.5.5.2-2 (for FR2) of TS 38.133, which correspond to the configured frequency range and DRX cycle for the first beam management operation. The UE 104 can use this evaluation period determination to configure its measurement behavior. For example, by determining this evaluation period, the UE 104 can 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 this evaluation period.

[0090] For example, for SSB-based candidate beam detection, the operation flow / algorithm structure 300 may calculate, at 308, an evaluation period T of frequency range 1 (FR1) as described in Table 8.5.5.2-1 of TS 38.133 评估 _CBD_SSB (in milliseconds (ms)) as follows, where T SSB is the period of the SSBs 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 not greater than 320 ms, T 评估

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

[0093] 2) For configurations where the DRX cycle is greater than 320 ms, T 评估 _CBD_SSB = ceil(3 × P × P CBD )

[0094] × T DRX ),

[0095] where the value of the parameter P is as described in Section 8.5.5.2 of TS 38.133 (e.g., having a value of one when the measurement gap does not overlap with any occasion of the SSBs in the monitored cell and otherwise based on the measurement gap repetition period).

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

[0098] The analog BF component can be coupled to one or more radio frequency (RF) chains. 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 to 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 that may reside in the baseband processor can provide BF weights to the analog / digital BF components to provide receive beams at the respective antenna panels. These BF weights can be determined by the control circuitry based on the received reference signal and the corresponding QCL / TCI information as described herein. In some embodiments, the BF weights can be phase shift values provided to the phase shifters of the analog BF component 912 or complex weights provided to the digital BF component 928. In some embodiments, the BF components and the antenna panels can operate together to provide a dynamic phased array capable of steering a beam in a desired direction.

[0100] In various embodiments, beamforming can include analog beamforming, pure digital beamforming, or hybrid analog-digital beamforming. Digital beamforming can utilize separate RF chains corresponding to the antenna elements.
