Abstract This document is to propose a MAC mechanism to support dynamic channel transfer procedure (DCT) for 802.11aj (60GHz) This contribution has been discussed in CWPAN group Jiamin Chen, Huawei

Background Proposed Channelization for 60GHz bands for 802.11aj Month Year doc.: IEEE 802.11-yy/xxxxr0 Background Proposed Channelization for 60GHz bands for 802.11aj There are 6 logical channels: 2 bands with 2.16GHz bandwidth (Channel 2 & 3), 4 bands with 1.08GHz bandwidth (Channel 5, 6, 7, 8); This proposed channelization Supports more than 3 logical channels for 802.11aj and keeps the backward compatibility with 802.11ad device； Channelization for 60GHz bands in China Jiamin Chen, Huawei John Doe, Some Company

Dynamic Channel Transfer(DCT) procedure for IEEE 802.11aj(60GHz) (1/2) Sept 2012 doc.: IEEE 802.11-012/xxxxr0 Dynamic Channel Transfer(DCT) procedure for IEEE 802.11aj(60GHz) (1/2) Some cases (Case 1 to Case 3): Request an existing PCP/AP to another vacant channel to allow other IEEE 802.11aj PCP/AP to establish a new BSS. Case 1 (Channel 6, 8 are occupied by existing BSS-1 and BSS-2 at 1.08GHz) New STA (to become PCP/AP-3) wants to start a new BSS-3 at 2.16GHz PCP/AP-3 request BSS-1 on channel 6 to move to channel 7, or request BSS-2 on channel 8 to move to channel 5 PCP/AP-1 or PCP/AP-2 shall assess the request against its capabilities and the impact on its BSS’s performance PCP/AP-1 or PCP/AP-2 may refuse the request If the request is confirmed, PCP/AP-3 may has a chance to use channel 2 or channel 3 Case 2 / 3 are similar to Case 1 Jiamin Chen, Huawei Xiaoming Peng / I2R

Dynamic Channel Transfer(DCT) procedure for IEEE 802.11aj(60GHz) (2/2) Sept 2012 doc.: IEEE 802.11-012/xxxxr0 Dynamic Channel Transfer(DCT) procedure for IEEE 802.11aj(60GHz) (2/2) Public action frame in 802.11spec Inter-BSS and AP to unassociated-STA communications Intra-BSS communication and so on Proposed new public action frame for the DCT procedure: DCT Measurement Request frame Requesting one or more STAs in the DCT responder PCP/AP’s BSS（PBSS or Infrastructure BSS）to measure a specified channel or all other channels within supported operating class. DCT Measurement Report frame Transmitting from the DCT responder PCP/AP to the DCT requester PCP/AP to report the result of channel measurement or refuse the DCT request. DCT Request frame Requesting DCT responder PCP/AP’s BSS to move to an available channel reported in the DCT Measurement Report frame. DCT Response frame Transmitting from the DCT responder PCP/AP to the DCT requester PCP/AP to confirm or refuse the DCT request. Jiamin Chen, Huawei Xiaoming Peng / I2R

Conclusion This presentation propose a mechanism referred to as Dynamic Channel Transfer .It can improve the network flexibility and channel efficiency for 802.11aj(60GHz), if the existing idle channel could not satisfy the networking requirements for the 802.11aj STA (to become PCP/AP).   Jiamin Chen, Huawei
