10.1 UE procedure for determining physical downlink control channel assignment
A set of PDCCH candidates for a UE to monitor is defined in terms of PDCCH search space sets. A search space set can be a CSS set or a USS set. A UE monitors PDCCH candidates in one or more of the following search spaces sets
- a Type0-PDCCH CSS set configured by
pdcch-ConfigSIB1 in MIB or by searchSpaceSIB1 in
PDCCH-ConfigCommon or by searchSpaceZero in
PDCCH-ConfigCommon for
a DCI format with CRC scrambled by
a SI-RNTI on the primary cell of the MCG
- a Type0A-PDCCH CSS set configured by searchSpaceOtherSystemInformation in PDCCH-ConfigCommon for
a DCI format with CRC scrambled by
a SI-RNTI on the primary cell of the MCG
- a Type1-PDCCH CSS set configured by ra-SearchSpace in
PDCCH-ConfigCommon for
a DCI format with CRC scrambled by
a RA-RNTI or a TC-RNTI on the primary cell
- a Type2-PDCCH CSS set configured by pagingSearchSpace in
PDCCH-ConfigCommon for a DCI format with CRC scrambled by a P-RNTI on the primary cell of the MCG
- a Type3-PDCCH CSS set configured by SearchSpace in PDCCH-Config with
searchSpaceType = common for DCI formats with CRC scrambled by
INT-RNTI,
SFI-RNTI,
TPC-PUSCH-RNTI,
TPC-PUCCH-RNTI, or
TPC-SRS-RNTI and,
only for the primary cell, C-RNTI, MCS-C-RNTI, or CS-RNTI(s), and
- a USS set configured by SearchSpace in PDCCH-Config with
searchSpaceType = ue-Specific for DCI formats with CRC scrambled by
C-RNTI,
MCS-C-RNTI,
SP-CSI-RNTI, or
CS-RNTI(s).

For a DL BWP, if a UE is not provided searchSpaceSIB1 for
Type0-PDCCH CSS set by
PDCCH-ConfigCommon, the UE does not monitor PDCCH candidates for
a Type0-PDCCH CSS set on the DL BWP.
The Type0-PDCCH CSS set is defined by the CCE aggregation levels and the number of PDCCH candidates per CCE aggregation level given in Table 10.1-1. If the active DL BWP and the initial DL BWP have same SCS and same CP length and the active DL BWP includes all RBs of the CORESET with index 0, or the active DL BWP is the initial DL BWP, the CORESET configured for
Type0-PDCCH CSS set has CORESET index 0 and the
Type0-PDCCH CSS set has search space set index 0.
For a DL BWP, if a UE is not provided searchSpaceOtherSystemInformation for
Type0A-PDCCH CSS set, the UE does not monitor PDCCH for
Type0A-PDCCH CSS set on the DL BWP. The CCE aggregation levels and the number of PDCCH candidates per CCE aggregation level for
Type0A-PDCCH CSS set are given in Table 10.1-1.
For a DL BWP, if a UE is not provided ra-SearchSpace for
Type1-PDCCH CSS set, the UE does not monitor PDCCH for
Type1-PDCCH CSS set on the DL BWP. If the UE has not been provided a Type3-PDCCH CSS set or a USS set and the UE has received a C-RNTI and has been provided
a Type1-PDCCH CSS set, the UE monitors PDCCH candidates for
DCI format 0_0 and
DCI format 1_0 with CRC scrambled by the C-RNTI in
the Type1-PDCCH CSS set.
如果没有给UE配置Type1-PDCCH CSS set，则UE不搜索Type1-PDCCH CSS set；
如果没有给UE配置Type3-PDCCH CSS set或者USS set，配置了Type1-PDCCH CSS set，则UE在Type1-PDCCH CSS set上使用C-RNTI接收UE专用数据。
------------------------------
If a UE
- is configured to monitor
a first PDCCH candidate for
a DCI format 0_0 and
a DCI format 1_0 from a CSS set and a second PDCCH candidate for
a DCI format 0_0 and
a DCI format 1_0 from a USS set in a CORESET with index zero on an active DL BWP, and
-
the DCI formats 0_0/1_0 associated with the first PDCCH candidate and
the DCI formats 0_0/1_0 associated with the second PDCCH candidate have same size, and
- the UE receives the first PDCCH candidate and the second PDCCH candidate over a same set of CCEs, and
- the first PDCCH candidate and the second PDCCH candidate have identical scrambling, and
- the DCI formats 0_0/1_0 for the first PDCCH candidate and
the DCI formats 0_0/1_0 for the second PDCCH candidate have CRC scrambled by either C-RNTI, or MCS-C-RNTI, or CS-RNTI
the UE decodes only the DCI formats 0_0/1_0 associated with the first PDCCH candidate.
公共搜索空间(CSS)和UE专用搜索空间(USS)的候选PDCCH，CCE位置相同，DCI长度相同，扰码相同，C-RNTI相同，则UE仅搜索公共搜索空间的首选PDCCH。

にこ健 その869 ☆Can't Get Enough☆
2021/9/4 12:00
为我们庆祝V6结成日的大家，万分感谢。
从今天起【LIVE TOUR V6 groove】就开始了。
因为当下的形势，举办演唱会有赞同的和反对的，我想有各种各样的考虑和想法。
虽然现在还不知道什么才是正确答案，但既然要做，就要实施彻底的感染对策，为了能平安地跑到最后一天，请大家多多协助。
为了不增加医护人员的负担，我认为需要V6、斯达夫共同和饭们通力协作努力预防感染。
能看观看演唱会的人也好，遗憾着来不了的人也好，为了能让爱着V6的大家用笑容迎接11月1日，彼此齐心协力吧。
来看演唱会的人，不仅仅是音乐会当天，在日常生活中，请注意不要做感染风险高的行为。
因为是最后一次，所以无论如何都想见你，这种心情我非常理解，但如果感觉身体不适的话，恳请你留在家里。
为了不发生那样的事每天的生活也注意吧。
接下来是演唱会中的关于预防感染的做法。
虽然不需要说话，但是请绝对不要说话。
V6！V6！V6！V6！V6！V6！！的平常的口号，请在心中默念。
当然，我非常欢迎拍手！！
有什么想诉说的事情的时候，请用拍子的强弱来表现。
或者，手语也非常欢迎。
如果中途身体不适，请向斯达夫举高手示意，
如果是以前的话，在演唱会中有人兴奋得扇起团扇，或者跳舞撞到旁边的人的时候，如果是平时的话，我想可以用语言提醒ta注意。
但是，这次是不可以交谈的，所以请各位，为了不给周围的人造成困扰，互相注意，好好欣赏。
然后，演唱会的时候就不用说了，入退场的时候，也许会兴奋地想说，但是要忍耐一下。
请绝对不要说话。
特别是退场的时候，会非常激动，想和朋友说话，但这也需要忍耐。
即使是在回家的电车里，和朋友一起来的人也不要说话，用LINE交流，请下点功夫。
到家之后，请尽情地在电话中分享感动。
关于口罩的注意事项，请参照前一篇『にこ健』【その868】。
像个唠叨的欧巴桑真是失礼了。
医療従事者、関係者の皆様、昼夜問わず最前線で戦い続け、日々、患者さんに真摯に向き合い、寄り添いご尽力くださりありがとうございます。
リスクのある中、働く全ての職業の皆様、生活を支えてくださる全ての皆様、ありがとうございます。
p.s.
今天，会有令人高兴的消息。
留在家里的各位也期待着哦。
今天一天也一起加油吧。
明天也一起加油吧。
