Abstract: A method and system for transmitting digital data by extending the sequence numbering range for a selective repeat transmission protocol are described. In accordance with one embodiment of the invention, data frames (70) are transmitted including an eight-bit sequence number (72) and a one-bit retransmit flag (74). The one-bit retransmit flag (74) indicates whether the frame is newly transmitted or retransmitted due to a failed first transmission. Transmit (50) and receive (52) systems each maintain a twelve-bit sequence number referred to as a "long sequence number" comprised of the eight-bit sequence number transmitted with each frame and a four-bit extension. The long sequence number is transmitted within a control frame (82) and the eight-bit sequence number is transmitted within the data frame (72).

Abstract: A method for generating a higher rate channel using a set of N lower rate channels, the method comprises generating a set of N sinusoids having a corresponding set of N phase offsets with predetermined phase rotations; upconverting said set of N lower rate channels using said set of N sinusoids and phase offsets yielding a set of upconverted signals; summing said set of upconverted signals yielding a summed signal whereby the peak-to-average amplitude of said summed signal is reduced based on said phase rotations; and transmitting said summed signal. A corresponding system is also disclosed.

Abstract: In some aspect restricted access nodes are as-signed to a designated common channel while access terminals that are in active communication with a macro access node may selectively be assigned to the designated channel. In some aspect an access terminal associated with macro access node may perform a handoff to a different carrier when the access terminal is in the vicinity of a coverage area of a restricted access node. In some aspect an access terminal associated with a macro access node may perform a handoff to a different carrier based on location information. In some aspect access to a restricted access node is controlled based on policy and/or based on operation of an access terminal associated with the restricted access node.

Abstract: A method for detecting delayed data frames in a transport function includes the steps of comparing a frame sequence counter with a predetermined threshold value, detecting a delayed frame if the sequence counter exceeds the threshold value, and processing the detected delayed frame accordingly. In an RLP data transport protocol, the delayed frame may be processed as a retransmitted frame. The threshold value may be proportional to the maximum number of frames sent in a given bundle times the maximum delay, in units of frame intervals, between frames sent simultaneously over the air in the same frame interval.

Abstract: In a multiple-access network, network access terminals (106) can communicate with network infrastructure access nodes (104), or conduct peer-to-peer communications (110). The access terminals are adapted to adjust the transmit power level in response to power control commands received from the access nodes and from other access terminals.
