Time synchronization of mobile channel sounding system

A mobile channel sounding transmitter comprising:

• a processing system including at least one processor;
• and
• a computer-readable medium storing instructions which, when executed by the processing system, cause the processing system to perform operations, the operations comprising:
• establishing a wireless side link between the mobile channel sounding transmitter and a channel sounding receiver;
• transmitting, to the channel sounding receiver, a wireless synchronization signal via the wireless side link;
• and
• transmitting at least one channel sounding waveform in accordance with the wireless synchronization signal, wherein the wireless side link comprises an in-band wireless link, wherein the in-band wireless link comprises a communication session via a first set of time and frequency resources, wherein the first set of time and frequency resources comprises a first set of frequencies and a first set of time slots, and wherein the at least one channel sounding waveform is transmitted via a second set of time and frequency resources, wherein the second set of time and frequency resources comprises the first set of frequencies and a second set of time slots, and wherein the time slots of the second set of time slots are non-overlapping with the time slots of the first set of time slots.

A non-transitory computer-readable medium storing instructions which, when executed by a processing system of a mobile channel sounding transmitter including at least one processor, cause the processing system to perform operations, the operations comprising:

• establishing a wireless side link between the mobile channel sounding transmitter and a channel sounding receiver;
• transmitting, to the channel sounding receiver, a wireless synchronization signal via the wireless side link;
• and
• transmitting at least one channel sounding waveform in accordance with the wireless synchronization signal, wherein the wireless side link comprises an in-band wireless link, wherein the in-band wireless link comprises a communication session via a first set of time and frequency resources, wherein the first set of time and frequency resources comprises a first set of frequencies and a first set of time slots, and wherein the at least one channel sounding waveform is transmitted via a second set of time and frequency resources, wherein the second set of time and frequency resources comprises the first set of frequencies and a second set of time slots, and wherein the time slots of the second set of time slots are non-overlapping with the time slots of the first set of time slots.
