RecordContent• Full-text of patent applications, granted patents, utility models and design patents
published in People's Republic of China from 1985 onwards.
• Records are available about a week after publication date with the complete content• Records contain bibliographic data including patent assignee and inventor, patent,
application, priority, and related (PCT) application data, IPC, CPC and EPC
classification codes, abstract, and full text of description and claims.
• Titles and abstracts are initially machine translated and about three months later
replaced by human translated text; descriptions and claims are machine translated.
• Independent claims and claim groups are searchable for all claims in English.
• Numeric values of 59 physical and chemical properties are searchable in about 20.000
variants of the base and additional units within all full text fields in English.
• Ultimate Owners are searchable in the field /UO and /UOS.
• Standardized and normalized patent assignee names are searchable in their own
fields /PAS and /PAN.
• Key terms, indexed and displayed in the field /KT, enhance retrieval of relevant
results, and make the evaluation of results more efficient. They are useful to broaden
search scope more precisely than Basic Index searches.
• The Locarno classification (/LCL) is available for design patents.
• Database records comprise all documents published for one application.
• Clipped images (mostly front-page images) are also included, when available.
• Some of the full text has been created by Optical Character Recognition (OCR)
software. Therefore, characters may be misinterpreted, or portions of the text may be
incomplete.

File Size• More than 48 million family records with more than 55 million publications (07/2024)• More than 36 million front page images (07/2024)

CNFULLDISPLAY and PRINT Formats
Any combination of formats may be used to display or print answers. Multiple codes must be separated by
spaces or commas, e.g., D L1 1-5 TI PA. The fields are displayed or printed in the order requested.
The information of the latest publication is displayed by default. To display the content for all levels of therecord you can combine all display fields and formats with the qualifier .M except FA, SCAN, and TRIAL. The
default display format is STD.M, i.e., all publication levels of one family in the STD format.
For displaying a particular publication of a database record, you can simply add for certain display field the kindcode to the appropriate display format, e.g., ALL.A. Fields that allow this are indicated by a number (3).
Hit-term highlighting is available for all fields. Highlighting must be ON during SEARCH to use the HIT, KWIC,
and OCC formats.

information feedback method for downlink data, and the method comprises
the following steps: acquiring processing capacity information of user
equipment, and reporting the processing capacity information to a basestation; acquiring data information of the downlink data packet;
according to the processing capability information and the data
information, calculating basic delay time required by the user equipment
for performing data decoding and ACK/NACK information coding on thedownlink data packet; receiving extra delay time issued by the basestation for the downlink data packet, wherein the extra delay time isused for indicating the position of a subframe for feeding back ACK/NACK
information corresponding to the downlink data packet; and selecting acorresponding subframe to feed back ACK/NACK information corresponding
to the downlink data packet according to the sum of the basic delay time
and the additional delay time. In addition, the embodiment of theinvention also discloses a base station and user equipment using themethod. The method can effectively reduce data transmission delay.
[DESC0001] Technical Field[DESC0002] The invention relates to the technical field ofcommunication, in particular to an ACK / NACK information feedback
method of downlink data and related equipment.
[DESC0003] Background Art[DESC0004] With the new generation 5G communication technology entering
the discussion phase, it is necessary to consider whether the system
structure and the access procedure that have been achieved in theexisting 4G Long Term (LTE) communication technology continue to be
adopted. On the one hand, since the communication system is a latecompatible technique, new technologies developed later tend to becompatible with prior art techniques; on the other hand, since 4G LTE
has already existed a large number of existing designs, much flexibilityof 5G must be sacrificed to reduce performance in order to achieve
