Summary
This document describes the proposed resolution on the comments related to RIT mode (sub category of Low Energy subgroup), provided in e (LB53 Consolidated Comment Database).
The following comments are addressed;
CID#1422 and 1437.

3. CID #1422: Command frame to be sent in RIT mode
<month year>
doc.: IEEE <doc#>
CID #1422: Command frame to be sent in RIT mode
Comment: “It is unable to send commands related to the association, the scan and the poll to the receiver using RIT.”
Proposed resolution: Accept in Principle
Discard “TxOption to indirect” of MCPS-DATA.request primitive to transmit data frame in RIT mode, so that any frame including MAC command can be transmitted in RIT mode. -> Revision to the draft provided in the next slide
Rationale: In order to transmit data frame in RIT mode in the current draft, device has to be in RIT mode (macRITperiod: non-zero) and set TxOption of MCPS-DATA.request to “indirect”. It is redundant and to delete setting of TxOption parameter will simplify the configuration, while it does not cause any issue for other functionalities.

4. Revision to draft on resolution of CID #1422
Data transmission in RIT mode
Change the title of this section to “RIT Transmission”
Replace the first paragraph with the following; “In order to transmit frame in RIT mode, the device shall at first stop its periodical transmission of RIT data request, enable its receiver, and wait at most macRitTxWaitTime for reception of RIT data request command frame from neighboring device. During this macRitTxWaitTime period, all other frames except RIT data request command shall be discarded.”
Replace the first sentence in the third paragraph with following;
“At the completion of frame transmission, corresponding confirm primitive shall be initiated by the MAC sublayer to the next higher layer.”

5. Revision of Figure 73.r Resolution to CID #1422
Delete “(TxOption: indirect)”

6. CID #1437: RIT Data request command frame
<month year>
doc.: IEEE <doc#>
CID #1437: RIT Data request command frame
Comment: “RIT data request command shall be processed in not only a RIT-mode device. There is a case that a LE device request data to no LE device which understand RIT request command.”
Proposed resolution: Accept in Principle
Replace the following text;
“This command shall only be sent and received in the RIT mode (macRitPeriod : non zero value).”
as provided below;
“This command shall only be sent and received by a device supporting RIT mode.”
