Selected frequency-table translation, not the complete 42-page form guide. PDF pages are one-based; the printed page number is one smaller. System labels and frequency values are retained. This is an ARIB document, not a MIC PDF. These excerpts specify frequencies and system names, not occupied bandwidth limits.
Representative frequency and arrangement fields
PDF pp.7–8 / printed pp.6–7:
- [8] 01局代表周波数 — Station 01 representative frequency: enter the representative low-group frequency for the system, in 0.1 MHz units using six digits. Tables 1–4 provide these frequencies; Tables 2–4 apply only to mobile entrance links.
- [9] 送信・受信 — Transmit/receive: indicate whether station 01 transmits (
送) or receives (受) at that low-group frequency. For 6.5/7.5 GHz, station 01 is the low-group transmitting station. - [10] 周波数配置 — Frequency arrangement:
N= normal;S= slot.
“Mobile entrance links” (携帯エントランス回線) is the source's label for the mobile-network backhaul tables below.

The registration-name column has paired forms such as 11HQ156M01 and 11HQ156MC1, likewise 11HS208M01/11HS208MC1 and 11DD260M01/11DD260MC1. Corresponding 15/18 GHz entries use the same pattern with their band prefix and channel number. The MC entries carry 偏波多重対応 — supports polarization multiplexing. The 18 GHz Q entries are 18G-Q25M01 through 18G-Q25M06.
