Problems solved by technology

Under the current technical conditions, the retransmission is determined by the response signal of the receiving end, which requires additional monitoring
In addition, after retransmission, the previous data is directly discarded, so that the previously sent air interface data is directly discarded, wasting bandwidth resources

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Direct Sequence Spread Spectrum (DSSS) technology is to spread the information to be sent to a very wide frequency band with a spread spectrum code sequence. Perform relevant processing to restore the sent information. As described in the background technology, the inventor of the present application believes after research that the current wireless retransmission mechanism is ineffective and cannot make reasonable use of resources, mainly due to one tr...

Abstract

The invention provides a data blind retransmission method. The method comprises steps that a group of to-be-sent data is labelled with multiple sequential numbers in a CDMA system, so as to obtain multiple data frames; a sending terminal sends the multiple data frames in sequence; after all data frames are sent, the sending terminal stops sending, a receiving terminal captures data frames throughsearching; and the receiving terminal combines content of all data frames and then demodulates. In the method, a group of data is labelled with multiple sequential numbers so as to obtain multiple data frames, after sending each time, the data frame is resent when a response signal is not monitored, after all data frames are sent, the receiving terminal searches to capture data frames, combines the content of found data frames and demodulates. In the prior art, monitoring is performed each time. The method lowers monitoring demands, reduces receiving energy consumption of the sending terminal,and lowers difficulty of system scheduling design.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data blind retransmission method. Background technique [0002] The main method of the current wireless retransmission mechanism is to confirm whether the information sent by itself is correctly received by the receiving end by reading the response of the receiving end after sending the data. If the answer is successful, stop sending. If the response fails to be sent, it will be resent until it is successfully sent or the maximum number of resends is exceeded. Under current technical conditions, the retransmission is determined by the response signal at the receiving end, which requires additional monitoring. In addition, after retransmission, the previous data is directly discarded, so that the previously sent air interface data is directly discarded, wasting bandwidth resources. Contents of the invention [0003] The purpose of the present invention is to provide a...
