Abstract: A method of operating a communication system is disclosed. The method includes forming a data frame having plural orthogonal frequency division multiplex (OFDM) symbols. A first set of preamble subcarriers is allocated to at least one of the OFDM symbols. A second set of data subcarriers is allocated to said at least one of the OFDM symbols.

Abstract: A method of BLE-Mesh communications includes providing a dual-mode BLE-Mesh device including dual-mode RF driver, dual-mode manager, a BLE stack for BLE operations, and a mesh stack for mesh operations in a BLE-mesh network having a BLE relay device and a functional end BLE device. The BLE-mesh device has a periodic set of time indexed data slots common throughout the BLE-mesh network which provides a BLE event timeline for BLE connection events. The dual-mode BLE device implements an event clustering algorithm that delays or advances mesh events with respect to a timing the BLE connection events for clustering together their respective occurrences into continuous BLE/Mesh events to reduce a duty cycle by reducing a number of transitions from active mode to sleep mode and from sleep mode to active mode. The BLE-Mesh device communicates in the BLE-mesh network using the continuous BLE/Mesh events with at least one mesh device.
