Method of implementing the Multi-MCS-Multi-Receiver Aggregation'' scheme in IEEE 802.11n standard

摘要

A method of communicating data over a wireless local area network according to an IEEE 802.11n proposal for Multi-MCS-Multi-Receiver Aggregation (MMRA), the improvement providing a modified PPDU format with MMRA signaling wherein the HT-SIG format is preserved. Instead of increasing the length of HT-SIG, a modified PPDU format with MMRA signaling is provided where the HT-SIG-MMRA is placed after the HT-LTF. In this manner, the original HT-SIG format is preserved, while accommodating the variable length of HT-SIG-MMRA. Further, in a modified HT-SIG structure, the Length and MCS of the HT-SIG-MMRA signaling part is placed in the LENGTH field and MCS field of HT-SIG1 (4 us), respectively, without changing the length of existing HT-SIG (8 us).
