• Suggested Resolution

• Non-directional DEV-DEV communication is followed by 802.15.3b
• Directional DEV-DEV communication
• Specify “Directional peer IE” to allow directional DEV and DEV communication in Regular CAP

Directional peer IE allows a pair of DEVs directionally communicate with each other in the Regular CAP

• Directional peer IE allows a pair of DEVs directionally communicate with each other in the Regular CAP

• Directional peer IE shall be formatted as illustrated in Figure xx.

• The SrcID field contains the DEVID of the source for the regular CAP
• The DestID field contains the DEVID of the destination for the regular CAP
• The Configuration field indicates the following
• b0 - 0 indicates request of directional communication, 1 indicates release of directional communication
• b1 - 0 indicates uni-directional, 1 indicates bi-directional communication
• The Allocated Superframes field contains the number of superframes as the allocating time for communication directionally between Source DEV to Destination DEV

Directional peer communication in the Regular CAP

• Directional peer communication in the Regular CAP

• Add the following sentences on 8.8.6.2
• “Before two peer DEVs communicate in the regular CAP, the two DEVs may perform beam forming, as described in 13.4, if they do not know the antenna directions to point to each other.
• To support directional peer communication in the regular CAP, the source DEV may send the PNC an Announce command with directional peer IE in which “Request/Release bit” is set to “1”, as described in x.x. If the PNC can allow the directional peer communication, the PNC shall includes the directional peer IE in the beacon to announce that the two devices will use regular CAP for directional peer communication.
• After the source and destination DEVs receive the directional peer IE in the beacon from the PNC , the two DEVs may switch their antenna directions and communicate with each other in the regular CAP. After the two devices complete directional peer communication, the source device may send the PNC an Announce command with directional peer IE in which “Request/Release bit” is set to “0”, and the PNC shall remove directional peer IE from its beacon.”
