Abstract: Embodiments herein achieve a method and system for selecting non-coherent spreading sequences with binary alphabets {0, 1} with variable spreading factors. The method generates circular shift equivalent sets of spreading sequences by circularly shifting base sequences with elements {1, 0} and having at least one variable spreading factor. The method determines whether each spreading sequence in the circular shift equivalent set meets pre-defined spreading sequence criteria. The spreading sequence criteria comprise balanced criteria, a non-repetition criteria, non-circular criteria, and conjugate criteria. Furthermore, the method selects the spreading sequence from expansions of at least one spreading sequence from the circular shift equivalent sets in response to determining that the spreading sequences in the circular shift equivalent sets meets the pre-defined spreading sequence criteria.

Abstract: The present invention provides a method and system for enabling machine type communication in a long term evolution (LTE) network environment. In one embodiment, a Physical (PHY) layer of an LTE protocol stack maps data bits in resource elements of a logical channel to resource elements of a physical channel. The PHY layer identifies the data bits intended for legacy devices but mapped to a first set of resource elements of machine type communication (MTC) devices and the data bits intended for the MTC device but mapped to the second set of resource elements of the legacy devices. Accordingly, the PHY layer remaps the data bits intended for the legacy devices to the second set of resource elements and the data bits intended for the MTC devices to the first set of resource elements prior to transmission.
