摘要:
The disclosure provides a method for transmitting Cognitive Pilot Channel (CPC) information, a radio access method and system based on CPC information, wherein the method for transmitting CPC information includes: dividing a CPC into a primary CPC for transmitting primary CPC information and a secondary CPC for transmitting secondary CPC information; loading the primary CPC information periodically into fixed physical resources, and sending the primary CPC information to a user equipment; after a base station receives a preset triggering event, loading the secondary CPC information into variable physical resources, and sending the secondary CPC information to the user equipment. In the disclosure, the base station loads the primary CPC information into fixed physical resources of an RAT according to an RAT coverage condition, reducing the amount of information required to be delivered by fixed physical resources, decreasing occupation of fixed physical resources, speeding up radio access of the user equipment; and after receiving a triggering event, the base station loads the secondary CPC information into variable physical resources and sends the secondary CPC information to the user equipment, thus implementing optimization of a user network and radio resources.

A multiple antenna mode control method based on an Access Point comprises the following steps: step 1, the Access Point periodically sends out a multiple antenna mode set or subset supported by the Access Point (S101); step 2, the Station reports a multiple antenna mode set or subset supported by the Station or, reports a multiple antenna mode set or subset supported by both the Station and the Access Point to the Access Point (S105); step 3, a multiple antenna mode is chosen from a multiple antenna mode set or subset supported by both the Station and the Access Point for communicating (S110). As a result, the Station and the Access Point can communicate in a reliable or high-speed antenna mode supported by both sending and receiving sides, and thereby the error frame rate is reduced, and the network throughput is increased.

A memory efficient, accelerated implementation architecture for BCJR based forward error correction algorithms. In this architecture, a memory efficiency storage scheme is adopted for the metrics and channel information to achieve high processing speed with a low memory requirement. Thus, BCJR based algorithms can be accelerated, and the implementation complexity can be 5 reduced. This scheme can be used in the BCJR based turbo decoder and LDPC decoder implementations.

The present invention provides a multiple antenna mode control method based on Station, including the steps: step 1 the Station reports a multiple antenna mode set or subset supported by the Station to the Access Point; step 2, the Access Point returns a multiple antenna mode set or subset supported by the Access Point to the Station, or returns directly a multiple antenna mode set or subset supported by both the Station and the Access Point to the Station; and step 3, a multiple antenna mode is chosen from a multiple antenna mode set or subset supported by both the Station and the Access Point for communicating between the Station and the Access Point. Thereby, a best transmission quality can be achieved during data transmission, and furthermore, the retransmission times and the error frame rate are reduced, and the network throughput is decreased.

The present invention discloses a method for quick and simultaneous determination of 16 inorganic anions and organic acids in tobacco by ion chromatography The retention behavior of inorganic anions and organic acids on the anion exchange column was investigated using potassium hydroxide produced by EGC-II KOH eluent autogenerator as eluent. The optimized gradient elution condition was obtained. The samples were prepared through extraction, filtration and dilution before analysis. The separation was performed on an anion exchange column. The time of the gradient elution program was 50 mins. Under the optimized conditions, the calibration of peak area for all the analytes were linear in the ranges of 105. The method in the present invention has the advantadges of simplicity, rapidity and accuracy, and is able to simultaneously determine 16 inorganic anions and organic acids in tobacco by one single time of injection.

Methods, computer-readable media, and systems are provided for monitoring a technical object during, for example, a handover and/or takeover of the technical object. In one embodiment, a business partner may receive an XML file for a technical object. The business partner may generate a new structure, to represent the technical object, based on the XML file. The business partner may retrieve a corresponding structure from a backend component. The business partner may preprocess the new structure by performing a consistency check. The consistency check may include comparing the new structure to the corresponding structure. The business partner may store the new structure in a backend component after the preprocessing is complete.
