Abstract:
1. A wireless packet communication method for transmitting X data packets simultaneously between two STAs over plural data transmission paths by using MIMO and a plurality of radio channels determined to be idle by carrier sense and/or by using a radio channel determined to be idle, X corresponding to a total number of MIMOs of the plurality of radio channels determined to be idle, where Dmax is a value corresponding to the maximum data size of the data packets, the wireless packet communication method comprising: using at least one of the STAs to perform the following steps: assessing the respective transmission rates of the plurality of data transmission paths and calculating a size ratio amongst the respective transmission rates, where the size ratio is a ratio between the respective transmission rates for each of the idle radio channels; obtaining from a transmission buffer associated with one of the STAs at least one data frame to be transmitted; fragmenting a data part extracted from a data field of the one data frame to be transmitted by applying the size ratio, to generate X data blocks such that each data block requires same amount of time for transmission from one STA to another STA; generating X data packets by adding, to each data block of the X data blocks, a header field containing control information that includes destination information and an FCS field containing an error checking code; transmitting the X data packets simultaneously over the plural data transmission paths; and generating X new data packets after the simultaneous transmission of the X data packets and continuously transmitting the new data packets without performing carrier sense, until a time corresponding to a transmission time of data packets generated from the one data frame passes.
