Abstract
A method for unsynchronized signaling between nodes in a network is described. The method includes partitioning a message for asynchronous transmission in a network into a plurality of symbols. A symbol includes a cyclic prefix. Causing the plurality of symbols to be transmitted (for example, via a transmitter) on one or more subcarriers allocated for asynchronous transmissions is also included in the method. A given symbol is transmitted so as to reduce a discontinuity between a previous symbol and the given symbol. The method may also include applying a phase shift to one or more symbols of the plurality of symbols. Transmitting may include transmitting at a transmission frequency, where a length of a transmission cycle is determined by the transmission frequency, and where a length of the cyclic prefix is equal to an integer number of transmission cycles. Apparatus and computer readable media are also described.
