A recently granted patent (Publication Number: US11888742B2) discloses a wireless node designed for wireless communication. The wireless node includes a memory and one or more processors configured to receive a configuration for incorporating extended routing information in backhaul adaptation protocol (BAP) headers. This extended routing information can include an extended destination field or an extended path field with a length exceeding 10 bits. The wireless node then transmits a packet containing this extended routing information in a BAP header based on the received configuration. Additionally, the BAP header includes an indication that it carries the extended routing information, which can be provided through various methods such as control bits, reserved bits, reserved values in header fields, or length fields.

Furthermore, the wireless node is capable of transmitting an indication of its ability to support BAP routing based on the extended routing information. The patent also covers methods of wireless communication performed by the wireless node, involving receiving packets with extended routing information in BAP headers and processing them accordingly. These methods also include transmitting indications of BAP routing support based on the extended routing information. Overall, the patent highlights advancements in wireless communication technology, particularly in optimizing routing information in BAP headers for enhanced efficiency and performance in wireless networks, whether for integrated access and backhaul (IAB) nodes or user equipment.
