In some embodiments, the PDCCH of the SCell may not be able to schedule the PDSCH and/or PUSCH on the PCell/PSCell. Certain systems (eg, NR Rel-16 and/or other systems) with Dynamic Spectrum Sharing (DSS) may have restricted/limited/reduced resources for PDCCH transmission of PCell/PSCell. Given constrained resources, one or more enhancements, such as NRPDCCH enhancements for cross-carrier scheduling, can be used/introduced to offload/share the PDCCH transmission of PCell/PSCell. One or more enhancements may include PDCCH of SCell scheduling PDSCH and/or PUSCH on PCell/PSCell. In some embodiments, the PDCCH blind decoding times (also called PDCCH blind decoding budget, PDCCH blind decoding budget, for example, number of times blind detection or PDCCH monitoring is performed).

Certain systems and/or technologies, such as 4th Generation mobile communication technology (4G) Long-Term Evolution (LTE) or LTE-Advanced (LTE-A) and/or 5G, may face/ Meet enhanced needs. Thus, 4G and 5G systems may have/use/enable, for example, support for enhanced Mobile BroadBand (eMBB), Ultra-Reliable Low-Latency Communication (URLLC) and/or massive Machine Type Communication ( massiveMachine-Type Communication, mMTC) characteristics. In some embodiments, the spectrum used for 4G can be reused/repurposed for 5G through DSS.

For example, in a 5G system, an SCell may include or correspond to a scheduling cell (for example, scheduling another SCell) and/or a scheduled cell. The PCell/PSCell may include or correspond to the calling cell, but may not include or correspond to the scheduled cell. In some embodiments, the PCell/PSCell may include or correspond to the scheduled cell and/or the scheduling cell. If the PCell/PSCell corresponds to the scheduled cell/the scheduling cell, the wireless communication device (eg, UE, terminal and/or serving node) may determine the PDCCH blind decoding times of the two scheduling cells for the same scheduled cell.

Various exemplary embodiments of the present disclosure for determining the number of PDCCH blind decoding times of a tuned cell having two tuning cells are described below.

A. Example 1

In some embodiments, the wireless communication device may determine/calculate/configure the number of PDCCH blind decoding times (Mmax) of the scheduled cell having at least two scheduling cells. PDCCH blind decoding times (Mmax) can be based on the first calling cell (for example, PCell (μ1)), the second calling cell (for example, SCell (μ2)), the calling cell with a higher SCS and/or the one with a higher SCS It is determined/calculated by the calling cell with low SCS. In response to determining the number of PDCCH blind decoding times (Mmax), the wireless communication device may determine the number of PDCCH blind decoding times for each calling cell (eg, M1max and/or M2max). The PDCCH blind decoding times of each calling cell (for example, M1max and/or M2max) may be determined based on (or according to) SCSs and/or scaling factors of at least two calling cells.

In some scenarios, such as a carrier aggregation scenario, a PCell/PSCell (eg, cell A) may be configured to be scheduled by an SCell (eg, cell B). A PCell/PSCell (eg, cell A) may support self-scheduling. An SCell (eg, cell B) may be configured as a calling cell. An SCell (eg, cell B) may support scheduling of a PCell/PSCell (eg, cell A). Therefore, a PCell/PSCell (eg, cell A) may have at least two scheduling cells (eg, cell A and/or cell B). The wireless communication device may determine/configure/calculate the number of PDCCH blind decoding times on the two scheduling cells for the same scheduled PCell/PSCell (for example, cell A). In some embodiments, the SCS of cell A (eg, PCell/PSCell) may correspond to μ1, while the SCS of cell B (eg, SCell) may include or correspond to μ2. The value of SCS may comprise or correspond to 15 kHz, 30 kHz, 60 kHz and/or 120 kHz.

(Mmax)。无线通信装置可以基于(或根据)第一主调小区、第二主调小区、具有较高/较大SCS的主调小区和/或具有较低/较小SCS的主调小区来确定/配置Mmax。例如，无线通信装置可以确定被调小区A(例如，PCell/PSCell)的Mmax。针对被调服务小区，对于具有SCS配置μ∈{0,1,2,3}的DL BWP，Mmax可以包括或对应于每个时隙的用于监控的PDCCH候选的最大数量。此外，无线通信装置可以为至少两个主调小区(例如，M1max和/或M2max)中的每一个确定/配置/计算PDCCH盲解码次数。无线通信装置可以通过使用(或根据)SCS和/或两个主调小区中的每一个主调小区的比例因子来确定/配置至少两个主调小区中的每一个主调小区的PDCCH盲解码次数。例如，无线通信装置可以确定/配置同一被调小区A的第一主调小区A和/或第二主调小区B(例如，SCell)的M1max/M2max。M1max和/或M2max可以包括或对应于针对被调服务小区的在主调小区上的具有SCS配置μ∈{0,1,2,3}的DL BWP的每个时隙的最大监控PDCCH候选数量。在本文讨论的实施例中，使用Mmax作为示例来确定PDCCH盲解码次数。与Mmax相关讨论的相同原理/操作可以应用于/属于/关联到Cmax/>

在本公开中，Mmax和Cmax(以及同样的M1max和C1max，和/或M2max和C2max)可以是可互换和/或等效的，或者一个可以包括另一个，或者一个可以替代另一个。因此，Cmax可用于确定PDCCH盲解码次数。以类似的方式，本文讨论的实施例使用PCell作为示例。然而，结合PCell讨论的相同/相似的原理/操作可以适用于PSCell。In some embodiments, the wireless communication device may determine/calculate the PDCCH blind decoding times of the tuned cell having at least two master tuning cells

(Mmax). The wireless communication device may determine/configure based on (or according to) the first calling cell, the second calling cell, the calling cell with a higher/larger SCS and/or the calling cell with a lower/smaller SCS Mmax. For example, the wireless communication device may determine the Mmax of the scheduled cell A (eg, PCell/PSCell). For the adjusted serving cell, for DL BWP with SCS configuration μ∈{0,1,2,3}, Mmax may include or correspond to the maximum number of PDCCH candidates for monitoring per slot. In addition, the wireless communication apparatus may determine/configure/calculate the number of PDCCH blind decoding times for each of the at least two calling cells (for example, M1max and/or M2max). The wireless communication device may determine/configure PDCCH blind decoding of each of the at least two calling cells by using (or according to) the SCS and/or the scaling factor of each of the two calling cells frequency. For example, the wireless communication device may determine/configure the M1max/M2max of the first scheduling cell A and/or the second scheduling cell B (for example, SCell) of the same scheduled cell A. M1max and/or M2max may include or correspond to the maximum number of monitored PDCCH candidates per slot for the DL BWP with SCS configuration μ∈{0,1,2,3} on the calling cell for the called serving cell . In the embodiments discussed herein, Mmax is used as an example to determine the number of PDCCH blind decoding times. The same principles/operations discussed in relation to Mmax can be applied/belonging/related to Cmax/>

In this disclosure, Mmax and Cmax (and likewise M1max and C1max, and/or M2max and C2max) may be interchangeable and/or equivalent, or one may include the other, or one may replace the other. Therefore, Cmax can be used to determine the number of PDCCH blind decoding times. In a similar manner, the embodiments discussed herein use PCell as an example. However, the same/similar principles/operations discussed in connection with PCells can be applied to PSCells.

In some embodiments, the wireless communication device may determine/configure a maximum number of blind detections of tuned carriers with at least two tuning cells. The wireless communication device may determine the maximum number of blind detections of the modulated carrier by using (or according to) one of at least two tuning cells. The wireless communication device may determine the maximum number of blind detections of the scheduled cell on each scheduling cell. In some embodiments, the wireless communication device may determine the maximum number of blind detections based on the SCSs of at least two calling cells and/or a predefined/configured scaling factor. Therefore, if the PCell is supported to be scheduled by the SCell, the PDCCH blind detection threshold of the scheduled cell having at least two scheduling cells can be explicitly/clearly determined. The system and method proposed in this paper can avoid PDCCH missing detection, because the threshold used for blind detection at the wireless communication device side is the same as that used at wireless communication nodes (such as ground terminals, base stations, gNBs, eNBs, transmission-reception points (Transmission - Reception Point (TRP) or service node) side blind detection thresholds are different/separated.

In some embodiments, the wireless communication device may determine/calculate/configure the number of PDCCH blind decoding times (Mmax) of the scheduled cell having at least two scheduling cells. The times of PDCCH blind decoding (Mmax) may be determined/calculated according to the first calling cell and the second calling cell. In some embodiments, Mmax may be determined according to the SCS and/or scaling factor of each of the at least two calling cells.

In some scenarios, such as carrier aggregation scenarios, the PCell/PSCell (eg, cell A) may be scheduled by the SCell (eg, cell B). A PCell/PSCell (eg, cell A) may support self-scheduling. An SCell (eg, cell B) may be configured as a calling cell. An SCell (eg, cell B) may support scheduling of a PCell/PSCell (eg, cell A). Therefore, a PCell/PSCell (eg, cell A) may have at least two scheduling cells (eg, cell A and/or cell B). The wireless communication device may determine/configure/calculate the number of PDCCH blind decoding times on the two scheduling cells for the same scheduled PCell/PSCell (for example, cell A).

In some embodiments, the scale factors of at least two calling cells may be configured/predetermined as P1 and/or P2 respectively. If μ1≠μ2, the maximum number of blind detections across time slots on the calling cell (for example, the calling cell with a larger SCS) may be the same.

In some embodiments, the wireless communication device may determine/configure a maximum number of blind detections of tuned carriers with at least two tuning cells. The wireless communication device may determine the maximum number of blind detections of the modulated carrier by using (or according to) two of the at least two scheduling cells. The wireless communication device may determine the maximum number of blind detections of the scheduled cell on each scheduling cell. In some embodiments, the wireless communication device may determine the maximum number of blind detections based on the SCS of each of the at least two scheduling cells and/or a corresponding predefined/configured scaling factor. Therefore, if the PCell is supported to be scheduled by the SCell, the PDCCH blind detection threshold of the scheduled cell having at least two scheduling cells can be explicitly/clearly determined. The systems and methods proposed herein can avoid PDCCH missed detection because the thresholds for blind detection at the wireless communication device side are different/separate/different from the thresholds for blind detection at the wireless communication node side.

C. Example 3

In some embodiments, the wireless communication device may determine an oversubscribe/drop mechanism. If the USS set used to schedule the PCell/PSCell(μ1) is located on the SCell(μ2) and/or only Mmax is defined/configured, the wireless communication device may determine an oversubscription/drop mechanism. In some scenarios, such as carrier aggregation scenarios, the PCell/PSCell (eg, cell A) may be scheduled by the SCell (eg, cell B). A PCell/PSCell (eg, cell A) may support self-scheduling. An SCell (eg, cell B) and/or a PCell/PSCell (eg, cell A) may be configured as the calling cell. Therefore, a PCell/PSCell (eg, cell A) may have at least two scheduling cells (eg, cell A and cell B). In some embodiments, the wireless communication device may determine/configure the number of PDCCH blind decoding times on two scheduling cells for the same scheduled PCell/PSCell (for example, cell A).

Therefore, Cmax can be used to determine the number of PDCCH blind decoding times. In a similar manner, the embodiments discussed herein use PCell as an example. However, the same/similar principles/operations discussed with PCells can apply/pertain to PSCells.

In some embodiments, the wireless communication apparatus may process PDCCH candidates/USS drops for each slot with SCS=μ1 or μ2 based on USS index and/or slot index. For example, the wireless communications apparatus can assign PDCCH candidates for monitoring to a set of user equipment (UE) specific search spaces (USS) according to (or based on) a USS index and/or a slot index. If the USS set used to schedule PCell(μ1) is located on SCell(μ2) and/or only Mmax is defined/configured, the wireless communication apparatus may handle PDCCH candidate/USS drop.

III. Method 1

In some embodiments, the wireless communication apparatus may process PDCCH candidates/USS discards per slot with SCS=μ1. For example, the wireless communication device may allocate the number of PDCCH candidates for monitoring in the time slots whose SCS is equal to the μ1. The maximum number of blind detections of M2 per slot with SCS=μ1 may comprise or correspond to M _max,μ1 −M1 _CSS,μ1 . In some embodiments, M1 may indicate/designate/provide blind detection candidates on cell A (eg, PCell/PSCell) for scheduling cell A. M2 may indicate/designate/provide blind detection candidates on cell B (eg, SCell) for scheduling cell A.

i.Scheme 1

If μ1 ≤ μ2, the wireless communications apparatus may process PDCCH candidates/USS discards according to the order of USS indices, followed by the order of slot indices with SCS equal to said μ2.

In some embodiments, the order of the USS index may comprise or correspond to an ascending order of the USS index. If the USS index is in ascending order with the accumulation of candidates, the wireless communication device may determine/configure the candidates for monitoring by using/comparing the maximum number of blind detections of M2 per slot with SCS=μ1. In some embodiments, the accumulated number of candidates may be less/less than the maximum number of blind detections of M2 per slot with SCS=μ1. All candidates in the USS can be monitored if the accumulated number of candidates does not exceed the maximum number of blind detections of M2 per slot with SCS=μ1. In some embodiments, the accumulated number of candidates including candidates in the USS with index "x"(USS#x) may exceed/more than the maximum number of blind detections of M2 per slot for SCS=μ1. If the accumulated number of candidates exceeds the maximum number of blind detections for M2 per slot with SCS=μ1, then USS #x in μ2 slot 2 ^μ2-μ1 number can all be discarded (e.g., scheme 1-1) . If the accumulated number of candidates exceeds the maximum number of blind detections of M2 per slot with SCS=μ1, USS#x in the ^μ2-μ1 number of μ2 slots 2 can be discarded according to (or based on) ascending order of slot index (eg, Scheme 1-2).

For example, cell A (eg, PCell/PSCell with μ1 = 15 kHz or other values) may support self-scheduling and/or carrier scheduling (CCS) for cell B (eg, SCell with μ2 = 30 kHz or other values). In this example, each slot #n with SCS=μ1 on the PCell/PSCell may include or correspond to two slots on the SCell (eg, slot #2n and/or #2n+1). The search space configured on the PCell/PSCell may include CSS with index 0 (CSS#0) with 6 candidates (or other values) and/or CSS with index 1 (CSS#0) with 6 candidates (or other values) 1) CSS. Therefore, _Mmax,μ1 -M1 _CSS,μ1 =44-6-6=32 per slot with SCS=μ1. Furthermore, USS#2 with 12 candidates (or other values) and a monitoring period of 1 slot can be counted/calculated as 2*12=24 candidates. Therefore, after accumulating USS#2, the number of remaining candidates may correspond to 32-24=8 per slot with SCS=μ1. Also, USS#3 with 6 candidates and a monitoring period of 1 slot may be calculated as 2*6=12 candidates. Therefore, after accumulating USS#3, USS#3 with 6 candidates may exceed the number of remaining candidates.

According to certain schemes (eg scheme 1-1), 2 ^μ2-μ1 number of candidates in USS#3 in μ2 slots may be discarded. Accordingly, candidates in USS #3 in slots #2n and/or #2n+1 on the SCell may be discarded (eg, candidates are not monitored). According to other schemes (eg scheme 1-2), candidates in 2 ^μ2-μ1 number of USS#x in μ2 slots may be discarded according to (or based on) ascending order of slot index. For example, 6 candidates (or other values) in USS #3 in slot #2n on the SCell may be accumulated. The number of candidates accumulated in USS #3 in slot #2n on the SCell may be smaller/less than the number of remaining candidates. Therefore, the number of remaining candidates may correspond to 8-6=2 per slot with SCS=μ1 (or other value). In addition, 6 candidates (or other values) can be accumulated in USS #3 in slot #2n+1 on the SCell. The accumulated candidates may exceed the remaining candidates, and therefore, USS #3 in slot #2n+1 on the SCell may be discarded.

ii. Option 2

If μ1 ≤ μ2, the wireless communications apparatus may process PDCCH candidates/USS discards according to the order of slot indices with SCS equal to μ2, and then according to the order of USS indices.

In some embodiments, the wireless communication device may process PDCCH candidates/USS discards slot by slot in a 2 ^μ2-μ1 number of μ2 slots. The wireless communication device may determine/configure candidates for monitoring in each slot by using an ascending order of USS indices with accumulated candidates. The wireless communication device may determine candidates for monitoring by using/comparing the maximum number of blind detections of M2 per slot with SCS=μ1. In some embodiments, the accumulated number of candidates may be smaller/less than the maximum number of blind detections of M2 per slot with SCS=μ1. Candidates in the USS can be monitored if the accumulated number of candidates does not exceed the maximum number of blind detections of M2 per slot with SCS=μ1. In some embodiments, the accumulated number of candidates including candidates in USS#x may exceed the maximum number of blind detections of M2 per slot with SCS=μ1. Candidates in USS#x may not be monitored if the accumulated number of candidates exceeds the maximum number of blind detections of M2 per slot with SCS=μ1.

For example, cell A (eg, PCell/PSCell with μ1 = 15 kHz or other values) may support self-scheduling and/or CCS for cell B (eg, SCell with μ2 = 30 kHz or other values). In this example, each slot #n with SCS=μ1 on the PCell/PSCell may include or correspond to two slots on the SCell (eg, slot #2n and/or #2n+1). The search space configured on the PCell/PSCell may include CSS with index 0 (CSS#0) with 6 candidates (or other values) and/or CSS with index 1 (CSS#0) with 6 candidates (or other values) 1) CSS. Therefore, _Mmax,μ1 -M1 _CSS,μ1 =44-6-6=32 per slot with SCS=μ1. Additionally, USS #2 may include a monitoring period of 12 candidates (or other values) and/or 1 slot. USS #3 may include 6 candidates (or other values) and/or a monitoring period of 1 slot.

In some embodiments, the wireless communication device may handle PDCCH candidates/USS drops in μ2 slot #2n. Candidates in USS #2 and/or USS #3 may be monitored (eg, not discarded). Therefore, the number of remaining candidates after accumulating USS #2 and/or USS #3 in μ2 slot #2n may correspond to each slot 32-12-6=14 with SCS=μ1. In addition, the wireless communication device can handle PDCCH candidates/USS drops in μ2 slot #2n+1. The wireless communication device may accumulate 12 candidates in USS #2 in μ2 slot #2n+1 on the SCell without exceeding the number of remaining candidates. Thus, the remaining number of candidates may include or correspond to 14-12=2 per slot with SCS=μ1. Also, 6 candidates may be accumulated in USS #3 in slot #2n+1 on the SCell, thereby exceeding the number of remaining candidates. In response to exceeding the number of remaining candidates, USS #3 in slot #2n+1 on the SCell may be discarded.

iii. Scheme 3

If μ1>μ2, the wireless communication apparatus may process PDCCH candidates/USS discards per slot with SCS=μ1 according to the maximum number of blind detections of M2 per slot with SCS=μ1. The number of candidates in the USS set of the second calling cell of the adjusted cell (for example, USS#x in the SCell) is counted as 2 ^μ2-μ1 multiplied by the number of candidates configured in the USS set (for example, 2 ^μ2-μ1 * M2_USS#x candidates).

In some embodiments, the wireless communication device may process PDCCH candidates/USS discards per slot with SCS=μ2 according to the maximum number of blind detections of M2 per slot with SCS=μ2, regardless of μ1≤μ2 or μ1>μ2.

例如，小区A(例如，具有μ1＝15kHz或其他值的PCell/PSCell)可以支持小区B(例如，具有μ2＝30kHz或其他值的SCell)的自调度和/或CCS。在该示例中，PCell/PSCell上的SCS＝μ1的时隙#n可以包括或对应于SCell上的至少两个时隙(例如，时隙#2n和/或#2n+1)。在PCell/PSCell上配置的搜索空间可以包括具有6个候选(或其他值)的索引为0的CSS(CSS#0)和/或具有6个候选(或其他值)的索引为1的CSS(CSS#1)。因此，对于SCS＝μ2的每个时隙的M2的盲检的最大数量可以包括或对应于SCS＝μ2的每个时隙22-0.5*(6+6)＝16。USS#2可能包括12个候选(或其他值)和/或不能超过剩余候选。响应于累加USS#2，剩余候选数量可能包括或对应于SCS＝μ2的每个时隙16-12＝4。此外，USS#3中的6个候选可以累加，从而超过剩余候选。因此，在SCell上的时隙#2n中的USS#3可以被丢弃。In some embodiments, the wireless communication apparatus may handle PDCCH candidates/USS discards per slot with SCS=μ2 by using a maximum number of blind detections of M2 per slot with SCS=μ2. The maximum number of blind detections for M2 per slot with SCS=μ2 may include or correspond to

or

For example, cell A (eg, PCell/PSCell with μ1 = 15 kHz or other values) may support self-scheduling and/or CCS for cell B (eg, SCell with μ2 = 30 kHz or other values). In this example, the slot #n with SCS=μ1 on the PCell/PSCell may include or correspond to at least two slots on the SCell (eg, slot #2n and/or #2n+1). The search space configured on PCell/PSCell may include a CSS with index 0 (CSS#0) with 6 candidates (or other values) and/or a CSS with index 1 (CSS#0) with 6 candidates (or other values) CSS #1). Thus, the maximum number of blind detections of M2 for each slot of SCS=μ2 may include or correspond to 22−0.5*(6+6)=16 per slot of SCS=μ2. USS #2 may include 12 candidates (or other values) and/or no more than remaining candidates. Responsive to accumulating USS#2, the number of remaining candidates may include or correspond to 16-12=4 per slot with SCS=μ2. Furthermore, the 6 candidates in USS#3 can be accumulated, thereby exceeding the remaining candidates. Therefore, USS #3 in slot #2n on the SCell can be dropped.

In another example, cell A (eg, PCell/PSCell with μ1 = 30 kHz or other values) may support self-scheduling and/or CCS of cell B (eg, SCell with μ2 = 15 kHz or other values). In this example, each slot #2n of SCS=μ1 on the PCell/PSCell and/or each slot #2n+1 of SCS=μ1 may include or correspond to slot #n on the SCell. The search space configured on PCell/PSCell may include CSS#0 with 6 candidates (or other values) and 1 slot cycle, and/or CSS#0 with 6 candidates (or other values) and 1 slot cycle CSS #1. Thus, the maximum number of blind detections of M2 for each slot of SCS=μ2 may include or correspond to 44-(6+6)-(6+6)=20 per slot of SCS=μ2. USS #2 may include 12 candidates (or other values) and/or no more than remaining candidates. Responsive to accumulating USS#2, the number of remaining candidates may include or correspond to 20-12=8 per slot with SCS=μ2. Also, the 6 candidates in USS#3 can be accumulated without exceeding the remaining candidates. Responsive to accumulating USS#3, the remaining number of candidates may include or correspond to 8-6=2 per slot with SCS=μ2. After accumulating 6 candidates in USS#3, 6 candidates may be accumulated in USS#4, thereby exceeding the remaining candidates. Therefore, USS #4 in slot #n on the SCell may be dropped.

In some embodiments, the wireless communications apparatus may process PDCCH candidates/USS discards per slot with SCS=μ1 and/or per slot with SCS=μ2 according to (or based on) USS/slot index. If a UE-specific search space (USS) for a tuned carrier having at least two tuning cells is located/included on one of the at least two tuning cells, the wireless communication device may PDCCH candidates/USS drops are processed in each slot and/or every slot with SCS=μ2. Handling PDCCH candidates/USS discards in the above manner can ensure/guarantee/confirm that the blind detection of modulated carriers with at least two tuning cells is less/less than the maximum number of blind detections on at least two tuning cells. In addition, by reserving as many PDCCH candidates/USS as possible, the blind detection capability of the wireless communication device can be fully/comprehensively used.

D. Example 4

In some embodiments, the wireless communication device may determine an oversubscribe/drop mechanism. If the USS set used to schedule the PCell/PSCell(μ1) is located on the PCell/PSCell(μ1), and the SCell(μ2) and/or only Mmax is defined/configured, the wireless communication device may determine an oversubscription/drop mechanism. In some scenarios, such as carrier aggregation scenarios, the PCell/PSCell (eg, cell A) may be scheduled by the SCell (eg, cell B). A PCell/PSCell (eg, cell A) may support self-scheduling. An SCell (for example, cell B) may be configured as a scheduling cell, wherein the SCell may support scheduling PCell/PSCell. Therefore, a PCell/PSCell (eg, cell A) may have at least two scheduling cells (eg, cell A and cell B). In some embodiments, the wireless communication device may determine/configure the number of PDCCH blind decoding times on two scheduling cells for the same scheduled PCell/PSCell (for example, cell A). In some embodiments, the SCS of cell A (eg, PCell/PSCell) may correspond to μ1, while the SCS of cell B (eg, SCell) may include or correspond to μ2. The value of each SCS may comprise or correspond to 15kHz, 30kHz, 60kHz and/or 120kHz.

In the embodiments discussed herein, Mmax is used as an example to determine the number of PDCCH blind decoding times. The same principles/operations discussed with Mmax can apply/belong to/involving Cmax

Therefore, Cmax can be used to determine the number of PDCCH blind decoding times. In a similar manner, the embodiments discussed herein use PCell as an example. However, the same/similar principles/operations discussed with PSCells can apply/belong to PCells.

In some embodiments, the wireless communication device may process PDCCH candidates/USS discards for each slot of SCS=μ1 or μ2 slots through USS index, calling cell index and/or slot index. For example, the wireless communication apparatus may allocate PDCCH candidates for monitoring to a user equipment (UE) specific search space (USS) set according to (or based on) a USS index, a calling cell index and/or a slot index. If the USS set used to schedule PCell(μ1) is located on PCell(μ1) and SCell(μ2), and/or only Mmax is defined/configured, the wireless communication device can handle PDCCH candidate/USS drop.

V. Method 1

In some embodiments, the wireless communication apparatus may process PDCCH candidates/USS discards per slot with SCS=μ1. For example, the wireless communication device may allocate the number of PDCCH candidates for monitoring in a time slot with an SCS equal to μ1. The maximum number of blind detections per slot M_USS with SCS=μ1 may comprise or correspond to M _max,μ1 −M1 _CSS,μ1 . In some embodiments, M_USS may include a candidate (M1_USS) for blind detection on Cell A (eg, PCell/PSCell) where Cell A is scheduled. M_USS may include a candidate (M2_USS) for blind detection on cell B (eg, SCell) where cell A is scheduled.

i.Scheme 1

If μ1 ≤ μ2, the wireless communications apparatus may process PDCCH candidates/USS discards according to the order of USS indices, followed by the order of slot indices with SCS equal to μ2.

In some embodiments, the order of the USS index may comprise or correspond to an ascending order of the USS index. If the USS index is in ascending order with the accumulation of candidates, the wireless communication device may determine/configure the candidates for monitoring by using/comparing the maximum number of blind detections of M2 per slot with SCS=μ1. In some embodiments, the accumulated number of candidates may be less/less than the maximum number of blind detections of M2 per slot with SCS=μ1. All candidates in the USS can be monitored if the accumulated number of candidates does not exceed the maximum number of blind detections of M2 per slot with SCS=μ1. In some embodiments, the accumulated number of candidates including candidates in the USS with index "x"(USS#x) may exceed/more than the maximum number of blind detections of M2 per slot with SCS=μ1. If the accumulated number of candidates exceeds the maximum number of blind detections of M2 per slot with SCS=μ1, USS #x in the μ2 slot 2 ^μ2-μ1 number can be discarded entirely (for example, Scheme 1-1). If the accumulated number of candidates exceeds the maximum number of blind detections of M2 per slot with SCS=μ1, USS#x in the ^μ2-μ1 number of μ2 slots 2 can be discarded according to (or based on) ascending order of slot index (eg, Scheme 1-2).

For example, cell A (for example, PCell/PSCell with μ1=15kHz or other values) may support self-scheduling and/or CSC of cell B (for example, SCell with μ2=30kHz or other values). In this example, each slot #n with SCS=μ1 on the PCell/PSCell may include or correspond to two slots on the SCell (eg, slot #2n and/or #2n+1). The search space configured on PCell/PSCell may include a CSS with index 0 (CSS#0) with 6 candidates (or other values) and/or a CSS with index 1 (CSS#0) with 6 candidates (or other values) CSS #1). Therefore, each time slot Mmax _,μ1 -M1 _CSS,μ1 =44-6-6=32 for SCS=μ1. Also, USS#2 on PCell/PSCell with 2 candidates (or other values) can be counted/calculated as 2 candidates. Therefore, after accumulating USS#2, the number of remaining candidates may correspond to each slot 32-2=30 with SCS=μ1. Also, USS#3 with 12 candidates and 1 slot monitoring period used on the SCell can be calculated as 2*12=24 candidates. Therefore, after accumulating USS#3, the number of remaining candidates may correspond to 30−24=6 per slot with SCS=μ1. Also, USS#4 with 6 candidates and 1 slot monitoring period may be calculated as 2*6=12 candidates. Therefore, after accumulating USS#4, USS#4 may exceed the number of remaining candidates.

According to certain schemes (eg, scheme 1-1), candidates of μ2 slot 2 ^μ2-μ1 number in USS#4 may be discarded. Accordingly, candidates in USS #4 in slots #2n and/or #2n+1 on the SCell may be discarded (eg, candidates are not monitored). According to other schemes (eg scheme 1-2), candidates in 2 ^μ2-μ1 number of USS#x in μ2 slots may be discarded according to (or based on) ascending order of slot index. For example, 6 candidates (or other values) in USS #4 in slot #2n on the SCell may be accumulated. The number of candidates accumulated in USS #4 in slot #2n on the SCell may be smaller/less than the number of remaining candidates. Thus, each slot 6-6=0 for which the remaining number of candidates may correspond to SCS=μ1 (or other value). Also, 6 candidates (or other values) can be accumulated in USS #4 in slot #2n+1 on the SCell. The accumulated candidates may exceed the remaining candidates, therefore, USS #4 in slot #2n+1 on the SCell may be discarded.

ii. Option 2

If μ1 ≤ μ2, the wireless communication apparatus may process PDCCH candidates/USS discards according to the order of the hosting cell index, followed by the order of the slot index with SCS equal to μ2, followed by the order of the USS index.

Second, the wireless communication apparatus may process PDCCH candidates/USS discards on the SCell according to (or based on) ascending order of USS indices and/or order of μ2 slot indices.

In some embodiments, the wireless communication device may process PDCCH candidates/USS drops on a slot-by-slot basis on SCells in a 2 ^μ2-μ1 number of μ2 slots. For example, cell A (for example, PCell/PSCell with μ1=15kHz or other values) may support self-scheduling and/or CCS of cell B (for example, SCell with μ2=30kHz or other values). In this example, each slot #n of SCS=μ1 on the PCell/PSCell may include or correspond to two slots on the SCell (eg, slots #2n and/or #2n+1). The search space configured on PCell/PSCell may include a CSS with index 0 (CSS#0) with 6 candidates (or other values) and/or a CSS with index 1 (CSS#0) with 6 candidates (or other values) CSS #1). USS#2 on PCell/PSCell may include 2 candidates (or other values). Therefore, M _max,μ1 -M1 _CSS,μ1 =44-6-6=32 on each time slot with SCS=μ1. USS#3 on the SCell may include 12 candidates (or other values) and/or a monitoring period of 1 slot. USS#4 on the SCell may include 6 candidates (or other values) and/or a monitoring period of 1 slot. First, the wireless communication device can handle PDCCH candidates/USS drops on PCell. Candidates in USS#2 may be monitored (eg, not discarded). Therefore, after accumulating USS#2, the remaining number of candidates may include or correspond to 32−2=30 on each time slot with SCS=μ1.

In some embodiments, the wireless communication device may handle PDCCH candidates/USS drops on SCells in μ2 slot #2n. Candidates in USS #3 and/or USS #4 may be monitored (eg, not discarded). Therefore, after accumulating USS #3 and/or USS #4 in μ2 slot #2n, the number of remaining candidates may correspond to 30-12-6=12 per slot with SCS=μ1. In addition, the wireless communication device may process PDCCH candidate/USS discard on the SCell in μ2 slot #2n+1. The wireless communication device may accumulate 12 candidates in USS #3 in slot #2n+1 on the SCell without exceeding the number of remaining candidates. Therefore, the remaining number of candidates may include or correspond to 12-12=0 on each slot with SCS=μ1. Also, 6 candidates may be accumulated in USS #4 in slot #2n+1 on the SCell, thereby exceeding the number of remaining candidates. In response to exceeding the number of remaining candidates, USS #4 in slot #2n+1 on the SCell may be discarded.
