Transmitter-directed transmission security is provided between a transmit node and a receive node. The transmit node selects transmission format for each data frame based on a transmission security scenario. Information related to the transmission format is communicated between the transmit node and the receive node, and the data frames are transmitted over a wireless communication link using the selected transmission formats.

Transmitter-directed security for wireless-communications

Entry of a terminal into a wireless communications network is facilitated for terminals which may operate in either frequency-division duplex or time-division duplex mode. Join request messages transmitted by the terminals include a duplex capability indicator defining a carrier frequency which can be used to response to the terminals.

Physical layer quality of service is provided for a wireless communication system by operationally adapting the physical layer format to the quality of service requirements of transmitted data. The physical layer formats for the data packets are selected based on the quality of service requirements of the data packets. Control information defining the formats is transmitted across the wireless communication link and the data packets are transmitted using the selected physical layer formats.
