Global TDD band

Frequency Band of 3GPP LTE TDD mode

3GPP define the following operating bands for LTE TDD mode in the specification "TS 36.101".

Band No.	Frequency band	Band width	Remark
33	1900 MHz - 1920 MHz	20 MHz	3G core band
34	2010 MHz - 2025 MHz	15 MHz	3G core band
35	1850 MHz - 1910 MHz	60 MHz	PCS 1900 uplink band
36	1930 MHz - 1990 MHz	60 MHz	PCS 1900 downlink band
37	1910 MHz - 1930 MHz	20 MHz
38	2570 MHz - 2620 MHz	50 MHz	3G extension band (EU, Africa, Asia etc. )
39	1880 MHz - 1920 MHz	40 MHz	TD-SCDMA band in China
40	2300 MHz - 2400 MHz	100 MHz	To be deployed in China
41	2496 MHz - 2690 MHz	194 MHz	US 2.6 GHz band
42	3400 MHz - 3600 MHz	200 MHz	EU 3.5 GHz band
43	3600 MHz - 3800 MHz	200 MHz	EU 3.5 GHz band
44	703 MHz - 803 MHz	100 MHz	APT700

 

Current spectrum allocations of TDD frequency band in China, Japan and Taiwan are shown below.

In China, Band38 (D band) , a part of Band40 (E band), Band34 (A band) and Band39 (F band） are assigned as TD-LTE, TD-SCDMA / TD-LTE, TD-SCDMA / TD-LTE,TD-SCDMA, respectively.

In Japan, a part of Band41 is assigned as AXGP (TD-LTE) and WiMAX, while PHS uses a part of Band39.

In Taiwan, a part of Band41 is assigned as WiMAX. Also, a part of Band39 is used by PHS and 3G TDD system.
