QUESTION: In 36.101 the E-UTRA chart says that Band 6 (830 - 840/875 - 885 MHz) is not applicable. Why is that, and what does that mean?

ANSWER: In 36.101 v9.0.0 (June 2009), table 5.5-1, the E-UTRA chart says that Band 6 (830 - 840/875 - 885 MHz) is not applicable. In Release-8 version of the specs, this statement is not present.

The answer to above question is present in 36.800. I quote it here from section 6.5:

The frequency arrangement of Band 6 and Extended LTE 800 (Band 19) is as follows.

- Band 6: 830-840MHz(UL), 875-885MHz(DL)
- Band 19: 830-845MHz(UL), 875-890MHz(DL)

In Japan, the commercial service in Band VI for UTRA has already been operated, so the Band VI remains handled as ever. On the other hand, there are no plans for the commercial service in Band 6 to be operated at least in Japan due to use Band 19 for E-UTRA. In this case, it is expected that the maintenances for Band 6 need to be continued in spite of not be in use and the misinterpretation that Band 6 is applicable like Band VI in Japan occurs. In order to prevent these problems from occurring, two solutions can be imagined that Band 6 is deleted or "Band 6 is not applicable" is added in 3GPP specification where the descriptions on Band 6 are not maintained any longer. The former is seemingly-simple, but it is difficult to predict the risk of influencing other specifications because there is no precedent for this. So, it is assumed that the latter is reasonable. Therefore the following two items are proposed.

Proposal 1 : The descriptions on Band 6 are not updated for the WI TR and the corresponding 3GPP specifications.

Proposal 2 : "Band 6 is not applicable" is added in TS36.101, TS36.104, TS36.141, and TS36.521-1 as shown in Table 6.5-1.

As you can see Proposal 2 has been accepted.
