Abstract: Method and apparatus for generating a set of generator polynomials for use as a tail biting convolutional code to operate on data transmitted over a channel comprises: (0) specifying a constraint and a low code rate for a tail biting convolutional code, where the low rate code is lower than 1/n (n being an integer greater than 4); (1) selecting valid combinations of generator polynomials to include in a pool of potential codes, each valid combination being a potential code of the low rate code; (2) determining first lines of a weight spectrum for each potential code in the pool and including potential codes of the pool having best first lines in a candidate set; (3) determining best codes of the candidate set based on the first L number of lines in the weight spectrum; (4) selecting an optimum code(s) from the best codes; and (5) configuring a circuit(s) of a data transceiver (60/90) to implement the optimum code(s).

Abstract: A network (20) comprises an authenticator node (22) and a server (24) such as an authentication, authorization, and accounting (AAA) server. A method comprises a terminal (30) sending authentication capabilities information (AC) across a network access interface (32) to the network (the authentication capabilities information provides an indication of authentication capabilities of the terminal). The network (20) then uses the authentication capabilities information to determine a first cryptographic value. The terminal (30) then uses the authentication capabilities information to determine a second cryptographic value. The network (20) compares the first cryptographic value and the second cryptographic value to authenticate the terminal.

Abstract: Mechanisms to interlace multiple legacy frames to enhance radio resource utilization are described. Also described are mechanisms to modify a low- latency frame structure to appear as legacy frames. In one aspect, partially blanked-out legacy frames are interlaced with time offsets so that they complement each other to leave no idle system time. To a legacy user equipment (920), the interlaced frame appears as normal legacy frames used by multiple legacy cells. In another aspect, the low-latency frame is modified to appear as an interlaced frame. Again to the legacy user equipment (920), the low-latency frame appears as legacy frames from multiple legacy cells. To the low-latency user equipment, the modified low-latency frame still appear as normal low-latency frame. In this manner, radio resources of the legacy base stations are optimally utilized. Also, low-latency base stations (910) are enabled to provide serves to the legacy user equipments (920) without wasting radio resources.
