Abstract: A method and an apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A method and apparatus of performing receive processing to reduce the probability of false acceptance of erroneous PANs are also disclosed. A transmit station generates a PAN check sequence (PCS) and performs a channel coding on a PAN field and the PCS. The transmit station scrambles the encoded bits of the PAN field and the PCS with a TBF-specific scrambling code. Because of the scrambling, the PCS decoding at a receive station will pass if the data block is received by an intended receive station, while the PCS decoding will fail if received by a non-intended receive station. Alternatively, the scrambling may be performed before the channel coding. Alternatively, the transmit station may combine the PAN field and a temporary flow identity (TFI) to generate a PCS.

Abstract: HIGH THROUGHPUT CHANNEL OPERATION IN A MESH WIRELESS LOCAL AREA NETWORK (WLAN) IS DISCLOSED. A MESH NETWORK (100) COMPRISES A PLURALITY OF MESH POINTS (102-118) AND A NETWORK MANAGEMENT ENTITY (NME). THE NME (140) IS CONFIGURED TO RETRIEVE CAPABILITY AND CONFIGURATION DATA FROM THE MESH POINTS (102-118). THE NME CONFIGURES AT LEAST ONE MESH POINT WITH RESPECT TO IEEE 802.11N CHANNELIZATION AND LEGACY PROTECTION MODE BASED ON THE CAPABILITY AND CONFIGURATION DATA.
