Framework and method for acknowledging multiple messages in UWB communication and ranging systems

A second device in a wireless communication system supporting ranging capability, the second device comprising:

• a processor configured to generate a ranging control message (RCM) comprising a multiple message receipt confirmation request (MMRCR) information, the MMRCR information indicating that multiple message receipt confirmation is requested;
• and
• a transceiver operably connected to the processor, the transceiver configured to:
• receive, from a first device, the generated RCM in a ranging block including a plurality of ranging rounds;
• and
• transmit, to the first device, a multiple message receipt confirmation message (MMRCM) to confirm receipt of multiple messages,
• wherein:
• the MMRCM comprises a ranging multiple message receipt confirmation information element (RMMRC IE) that includes an MMRC list length field and an MMRC list field,
• the MMRC list length field indicates a number of elements in the MMRC list field, and
• the MMRC list field comprises an address field, an MMRC bitmap length field, and an MMRC bitmap field comprising a binary bitmap string.
