Embodiment Construction
[0062] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0063] The invention discloses a device for solving the MSDU / MMPDU segment reorganization problem in WLAN by fragmentation. The components include a receiving buffer area RxBuff, a fragmentation occupation register, a fragmentation management register, and a fragmentation index register, wherein:
[0064] The receiving buffer area is divided into N slices in units of M bytes for storing data of MSDU / MMPDU;
[0065] The slice occupation register is divided into N bits, wherein the I-th bit corresponds to the I-th slice of RxBuff, if the slice is occupied, then the position is 1, otherwise it is set to 0;
[0066] The fragment index register is divided into N records, and each record marks one of the data fragments of the MSDU / MMPDU and the index information of the subsequent data fragments.
[0067] The fragmentation management register is divided into K records, and...
