Day4--PM
task6 target costing
1.step:①product specifications，external market research②selling price③profit④target cost⑤estimated cost⑤cost gap=EC-TC(首先要判断是否存在，即只有在EC＞TC的时候才会有gap；其次计算EC时，包含生产成本和非生产成本 但必须是专为其而发生的★)
2.margin~based on price; mark-up~based on cost
3.closing cost gap(原则: EC↓，TC不变)
①choose a cheaper material without compromising quality:⑴alternative materials ⑵argue cheaper price(bulk buying→discount or new supplier)
②reduce labour cost without affecting quality:⑴overtime but pay little or nothing，however lead to affect morale\work quality\legal action ⑵new staffs，however experience\quality\training ⑶ training staffs→efficiency
③improve productivity(automation or more efficient technology)
④eliminate non-value added activities(use value&esteem value)
⑤try to use fewer parts without influence quality(simply the design)
attention:cost reduction may affect the value of the product
4.service industry服务业不适用目标成本法:Simultaneity同时性，Heterogeneity异质性，Intangibility无形性，perishability无法存储性，no transfer of ownership
5.implications~cost control: life cycle costing just pay attention to cost reduction →target cost control is a part of development of the product
6.note:
①if there is a cost gap，the product may be manufactured
②target costing is not suitable for the department which is free of charge to customers
③target costing is suitable for new product that has no existing market
④target costing is not suitable for industry that has a larger fixed cost base

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。

备注：
first PDCCH candidate: 公共搜索空间的候选PDCCH
second PDCCH candidate: 专用搜索空间的候选PDCCH
