Techniques for signaling extended sizes for Medium Access Control (MAC) Protocol Data Unit (MPDU), Aggregated MPDU (A-MPDU) and Aggregated MAC Service Data Unit (A-MSDU) frame formats. A first technique proposes modifications to the current specifications of the IEEE 802.11n standard in order to allow for longer MPDUs in an A-MPDU. This technique reuses the IEEE 802.11n signaling format and utilizes reserved bits to convey the new information, i.e. an indication that the maximum length of a MAC RDU, MPDU frame, of an A-MRDU, or of an A-MSDU is respectively greater than 4095 bytes. 64 kilobytes and 7935 bytes. The second technique proposes a new signaling mechanism to convey the extended sizes for the MPDU, A-MPDU and the A-MSDU through a very high throughput (VHT) capability element. One or more bits may be added to the delimiter field. In particular, the length field within the delimiter field has normally 12 bits. Two additional bits are added from the "reserved field" within the delimiter field to the length field (hence, 14 bits in total). |
