First Claim
1. A method for wireless communication, comprising:
- configuring a radio of a first device to operate in accordance with a resource-spread multiple access (RSMA) technology in accordance with one of a plurality of modes of operation;
spreading encoded information over time-domain resources to obtain a single carrier data signal;
in a first mode of operation, transmitting the single carrier data signal through a radio frequency front end (RFFE) of the first device to an entity in a wide area network; and
in a second mode of operation;
(a) spreading the single carrier data signal across different sub-channels to obtain an orthogonal frequency division multiplex waveform (OFDM waveform); and

Abstract
Methods, apparatus, and systems for wireless communication are provided. A method for wireless communication using a single radio air interface includes configuring a radio air interface of a first device to operate in accordance with a first variant of resource-spread multiple access technology, communicating wirelessly from a first device to a base station of a wide area network using the first variant of resource-spread multiple access technology, reconfiguring the radio air interface to operate in accordance with a second variant of resource-spread code division multiple access technology, and communicating wirelessly with a second device in a mesh network subsequent to reconfiguring the radio. The first device and the second device communicate wirelessly at power levels below a power level threshold selected to cause the base station to ignore transmissions between the first device and the second device.
