Provided are a positioning method, apparatus and system, a layout method for a positioning system and a storage medium. A plurality of labels is laid with preset positioning precision in an area to be positioned, where each label among the plurality of labels carries label information, where the label information corresponds to position information of a position of the each label. A position acquisition device reads first label information on a label at a distance not greater than the preset positioning precision from the position acquisition device; and the position acquisition device determines first position information of the position acquisition device according to the first label information.

A method for Hybrid Automatic Repeat Request (HARQ) combination is disclosed. The method includes that: externally configured parameters relevant to HARQ combination are received, and an identifier ddr2switch of DDR2 switching is calculated to acquire addresses involved before and after the HARQ combination; it is determined, according to the parameters and the addresses involved before and after the HARQ combination, whether the HARQ combination is needed to be performed; and when it is determined that the HARQ combination is needed to be performed, data in a DDR2 are read and stored into a first data cache random access memory RAMA; and a HARQ combination calculation is performed, and the calculation result is stored into a second data cache random access memory RAMB. A device for HARQ combination is further disclosed. The technical solutions provided in the disclosure are based on a latest interference cancellation algorithm, greatly increase the success probability of decoding, saves the storage space of a DDR2 and improves the reading or writing efficiency.

A method for reducing the fitting thrust of golden finger () and a PCB (). The method and the PCB () solve the problem of excessive inserting force of the golden finger () of the prior art, through modifying the shape of the edge of the PCB (), the edge of the PCB open reeds of a connector () at different time. The PCB () has at least one concave edge section or at least one convex edge section or at least one tilt edge section, and the edge can further be beveled. The bonding pads of the golden finger can be assorted, pin ends of a part of golden fingers () can be partially removed or these golden fingers can be completely removed, the pin ends of a part of golden fingers () can be preserved. Through the method, the purpose of reducing the fitting thrust upon inserting the PCB () into the connector can be achieved.
