Coverage extension using configurable reflectors

A method of wireless communications at a channel engineering device, comprising:

• receiving, from a wireless device, a message that configures the channel engineering device with one or more signaling directions and a first periodicity for transmitting a set of synchronization signals, wherein the one or more signaling directions and the first periodicity are configured for adjusting a coverage area of the set of synchronization signals after transmission by the wireless device;
• receiving the set of synchronization signals from the wireless device in accordance with a second periodicity for receiving the set of synchronization signals, wherein the first periodicity is based at least in part on the second periodicity and is different from the second periodicity;
• and
• transmitting the set of synchronization signals to one or more other wireless devices in accordance with the first periodicity and the one or more signaling directions.

A method of wireless communication at a first wireless device, comprising:

• receiving a set of synchronization signals transmitted by a second wireless device;
• determining whether the set of synchronization signals were received directly from the first wireless device or via a channel engineering device that modifies a coverage area of the set of synchronization signals, wherein the determination is based at least in part on a first periodicity for receiving the set of synchronization signals and a second periodicity for receiving the set of synchronization signals;
• and
• transmitting, to the second wireless device, a message that comprises an indication of whether the set of synchronization signals were received by the second wireless device directly from the first wireless device or via the channel engineering device based at least in part on the determination.

An apparatus, comprising:

• a processor;
• and
• a memory coupled with the processor, wherein the memory comprises instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, to a channel engineering device and one or more other wireless devices, a set of synchronization signals in accordance with a first periodicity associated with synchronization signal burst transmissions;
• and
• transmit a message to configure the channel engineering device with one or more signaling directions and a second periodicity for the channel engineering device to transmit the set of synchronization signals, the second periodicity being different from the first periodicity, wherein the one or more signaling directions and the second periodicity are configured for adjusting a coverage area of the set of synchronization signals after transmission from a first wireless device.
