Section: 5.2.2 - Largest channel bandwidth standalone SAR test requirements - QPSK with 50% RB allocation Footnote 7.
The footnote describes the required RB counts for 50% RB allocation testing, but then goes on to state when the RB is offset to the middle of the channel bandwidth. Should these RB counts apply for any 50% RB allocation testing, regardless of position in the channel? Please consider an edit to the following:
Use 3, 8, 12, 25, 36, and 50 RB allocations, respectively, for 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz channel bandwidths when the RB is offset to the middle of the channel bandwidth.
Use 3, 8, 12, 25, 36, and 50 RB allocations, respectively, for 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz channel bandwidths for 50% RB allocation tests set to the lower edge, middle, or upper edge of the required test channel.

Section: 4.1 - Frequency range and channel bandwidth, Footnote 4.
Are there any special considerations for multiple channel bandwidths functional in a particular LTE band in light of the channel selection criteria noted in this footnote? Perhaps the FCC should set the number of test channels based on the largest operational bandwidth?

Section: 4.1 - Frequency range and channel bandwidth, Footnote 3.
Please clarify the guidance provided in this footnote. What is meant by channel plan, and how is this expected to be understood and assessed by third party test labs that are not provided information on equipment and network deployments?

To whom it may concern,
With regards to this draft KDB, we are concerned with the inconsistency in the language throughout the publication. Specifically, section 5.2, which discusses measurement procedures for the largest channel bandwidth, makes mention of REPORTED SAR and seems to use this as the criteria for applying test reduction. However, in section 5.3, which discusses SAR measurement for other channel bandwidths, the criteria used here is the MEASURED SAR from section 5.2.
We would like to know if the cause of this inconsistency is merely an insignificant oversight, or if indeed the intent here was to use MEASURED SAR as the criteria for applying test reduction.

MiCOM Labs has found no significant problems with the proposed SAR Evaluation Considerations for LTE devices, and applauds FCC for moving this procedure off the PBA list in a timely manner.
Note: It is important to understand that the staff guidance provided in the KDB is intended to assist the public in following Commission requirements and does not constitute rules.
