First Claim
1. A method for wireless communication, comprising:
- receiving wide area network (WAN) scheduling information from downlink signals received at a first device from an entity of a WAN when the first device is configured for a first mode of communication;
determining a mesh network schedule based on the WAN scheduling information;
spreading encoded information to obtain a single carrier data signal;
when the first device is configured for the first mode of communication, transmitting the single carrier data signal through a radio frequency front end (RFFE) of the first device to the entity of the WAN; and
when the first device is configured for a second mode of communication;
(a) spreading the single carrier data signal across different sub-channels to obtain an orthogonal frequency division multiplex (OFDM) waveform; and
(b) transmitting the OFDM waveform through the RFFE to a second device in accordance with the mesh network schedule,wherein the WAN scheduling information is used to control switching logic that selects between the single carrier data signal and the OFDM waveform to provide input to the RFFE.

Abstract
Methods, apparatus, and systems for wireless communication are provided. A method for wireless communication includes configuring a first device for a first mode of communication, receiving wide area network (WAN) scheduling information from downlink signals received from a network entity when a radio air interface of the first device is configured for the first mode of communication, configuring the first device for a second mode of communication, determining a mesh network schedule based on the WAN scheduling information, and communicating wirelessly with a second device in accordance with the mesh network schedule when the radio air interface is configured for the second mode of communication. The first device and the second device may communicate at power levels below a power level threshold selected to cause the network entity to ignore transmissions between the first device and the second device.
