Section: 8.51.3 Macro eNodeB ID
Content: The Target Type is Macro eNodeB ID for: - handover to E-UTRAN Macro eNodeB; - RAN Information Relay towards E-UTRAN; and - a TNL address discovery response of a candidate en-gNB via the S1 interface or via inter-system signalling (see clauses 22.3.6.2 and 22.3.6.3 of 3GPP TS 36.300[ Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 ]  [19]). In this case the Target ID field shall be coded as depicted in Figure 8.51-2. Figure 8.51-2: Target ID for Type Macro eNodeB The Macro eNodeB ID consists of 20 bits. Bit 4 of Octet 9 is the most significant bit and bit 1 of Octet 11 is the least significant bit. The coding of the Macro eNodeB ID is the responsibility of each administration. Coding using full hexadecimal representation (binary, not ASCII encoding) shall be used.
