Features
The WLAN device technology uses an internal coexistence interface to
exchange request/grant with the BCA. Features include:
• Packet-based request signaling with direction and priority information
• 1- or 2-bit priority signaling to support 4 priority levels
• Multiple WLAN RX request trigger sources, including early prediction
• WLAN TX request cancellation and abort if grant denied or revoked in
middle of request
• 802.11n A-MPDU treated as single packet
• Programmable mask allows each frame type to be mapped to a priority
• Default setting puts response frames (ACK), beacons, and QoS frames
as high priority
• WLAN TX and RX have separate priority mask
• Programmable mask allows each transmit queue to be mapped to a
priority
• Queue-based mapping is optional for software-generated frames only
