Innovation Solution
A method and apparatus for transmitting and receiving index-based address information in UWB wireless networks by generating an address map and performing address indexing using a 1-octet address index, involving the exchange of control messages and frames with association request and response commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional address fields are used in UWB wireless networks, then complete address information can be transmitted, but the message size increases and transmission efficiency decreases
Solution Approach 1:
The patent creates an address map that stores the correspondence between index values and complete address information. Instead of transmitting full addresses, only index values (copies or references) are transmitted in messages. The receiving device uses these indexes to retrieve complete address information from the address map, thereby reducing message size while maintaining complete address functionality.
Solution Approach 2:
The address map serves as an intermediary between the transmitted index values and the actual address information. Rather than directly transmitting complete addresses, the system uses indexes as intermediaries that point to the address map, which then provides the full address information. This intermediary mechanism enables efficient transmission while preserving complete address capability.
2Productivity
If address indexing is implemented to reduce message size, then transmission efficiency improves, but the system complexity increases due to address map management
Solution Approach 1:
The address map is established and configured in advance before actual address transmission occurs. During the association process or network setup phase, the complete address information and corresponding index values are pre-mapped and stored. This preliminary action ensures that during normal communication, only simple index lookups are needed, minimizing runtime complexity while maintaining transmission efficiency.
3Quantity of substance
If 1-octet address indexes are used instead of full addresses, then the address field size is reduced, but the addressing capability may be limited
Solution Approach 1:
The patent transitions from a one-dimensional address representation (direct address transmission) to a two-dimensional structure consisting of index values and an address map. The 1-octet index serves as a compact key in the first dimension, while the address map provides the second dimension that expands the addressing capability. This dimensional transformation allows limited-size indexes to access a much larger address space, effectively resolving the contradiction between size reduction and capability maintenance.

AI summary
Disclosed are a method and an apparatus for transmitting or receiving index-based address information in an ultra-wideband wireless network system. The method performed by a first device in an ultra-wideband (UWB) wireless network system, according to an embodiment of the present disclosure, may comprise the steps of: transmitting a control message including an information element (IE) related to discovery; receiving a first frame including a combination request command from a second device; and in response to the combination request, transmitting a second frame including a combination response command to the second device. Here, the combination response command may include address information regarding the second device. Here, on the basis that address indexing based on a 1-octet address index is used, the address information may be designated as a 1-octet address index corresponding to an address of the second device.
