Additional PIB table entry needed <month year> doc.: IEEE 802.15-<doc#> 11 2003 Additional PIB table entry needed Comment Type: Errata Comment: The MAC requires knowledge about the power source of the node for assembling the capability information field of the association request command. (7.3.1.1.2). The MAC does not have any mechanism for getting this information. Solution: Add an additional attribute to the MAC PIB table called macPowerSource Jose Gutierrez and Marco Naeve, Eaton Corp. <author>, <company>

Missing status enumeration 11 2003 Missing status enumeration Comment Type: Errata Comment: When performing an active scan, the MAC may not be able to send a beacon request commend due to a busy channel. However, the MAC can not indicate this status in its MLME-SCAN.confirm primitive (7.1.11.2.1). Solution: Add CHANNEL_ACCESS_FAILURE as valid status to the MLME-SCAN.confirm primitive. Jose Gutierrez and Marco Naeve, Eaton Corp.

Missing status enumeration 11 2003 Missing status enumeration Comment Type: Errata Comment: When a MAC sub-layer issues a PD-DATA.request but the transceiver is already busy transmitting, the PD-DATA.confirm need not be able to indicate this status. Solution: Add BUSY_TX as valid status to the PD-DATA.confirm primitive. Jose Gutierrez and Marco Naeve, Eaton Corp.

PHY Simplification Comment Type: Corrigendum 11 2003 PHY Simplification Comment Type: Corrigendum Proposal: To reduce complexity of the PHY layer remove BUSY_RX, BUSY_TX, and FORCE_TRX_OFF from the PHY enumerations. Jose Gutierrez and Marco Naeve, Eaton Corp.

868 MHz PHY Enhancement Comment Type: Corrigendum 11 2003 868 MHz PHY Enhancement Comment Type: Corrigendum Proposal: To expand number of channels offered in the 868 MHz band according to the new European regulations. Jose Gutierrez and Marco Naeve, Eaton Corp.

Remove Parameter from MAC Reset 11 2003 Remove Parameter from MAC Reset Comment Type: Corrigendum Proposal: Remove the SetDefaultPIB parameter from the MLME-RESET.request primitive to reduce complexity. This parameter specifies if MAC PIB tables is reset or not. Purpose of reset is to go to a default state why keep PIB values? Jose Gutierrez and Marco Naeve, Eaton Corp.

Beacon Payload Comment Type: Corrigendum 11 2003 Beacon Payload Comment Type: Corrigendum Issue: Assuming a higher layer attaches additional information as payload to the MAC beacons, during scans the MAC will interrupt the higher layer for each incoming beacon using the MLME_BEACON_NOTIFY.indication. MAC and higher layer will collect duplicate information. Proposal: Originally beacon payload intended for communicating a Cluster ID. Remove the beacon payload from the beacon frame and the PIB table. Jose Gutierrez and Marco Naeve, Eaton Corp.

Association in non-beacon networks 11 2003 Association in non-beacon networks Comment Type: Corrigendum Issue: The association response frame is sent using indirect transmission. Device polls coordinator after aResponseWaitTime. Introduces significant delay (490ms @ 2.4GHz, 768ms @ 915MHz, 1.54s @ 868MHz) in non-beacon networks. Proposal: Allow association response frame to be sent directly in non-beacon networks. Jose Gutierrez and Marco Naeve, Eaton Corp.

Optional GTS Comment Type: Corrigendum 11 2003 Optional GTS Comment Type: Corrigendum Proposal: Support Pat Kinney’s proposal to make GTS optional. Jose Gutierrez and Marco Naeve, Eaton Corp.
