Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al. VInko Erceg, Broadcom

12 Month Year doc.: IEEE /xxxxr0 May 2010 MAC challenges As discussed in /572r0, the primary challenge for the MAC is how to deal with directional communication, which is used to combat the high propagation loss in 60GHz Device discovery becomes a non-trivial problem Devices need to find the direction for communication, which necessitates the support for beamforming ( /1153r2) DCF has limitations in the presence of directionality How to exploit spatial frequency reuse in face of directional communication ( /782r0) Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al. VInko Erceg, Broadcom

13 New MAC features (described in detail in separate presentations)
Month Year doc.: IEEE /xxxxr0 May 2010 New MAC features (described in detail in separate presentations) A new network architecture named Personal Basic Service Set (PBSS), while retaining the existent network architectures Channel access that support directionality and spatial frequency reuse, including both random access and scheduled access A unified and flexible beamforming scheme that can be tuned to simple, low power devices as well as complex devices Enhanced security (GCMP), link adaptation and power saving Multi-band support (fast session transfer) Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al. VInko Erceg, Broadcom

14 The Personal BSS (PBSS)
May 2010 The Personal BSS (PBSS) New network architecture in addition to infrastructure BSS and IBSS, which are also supported PBSS is defined to address some unique usages and challenges of 60GHz communication Usages: Rapid sync-n-go file transfer, projection to TV/projector, etc. Challenges: directional channel access, power saving, etc. More details in /391r0 Ad hoc network similar to the IBSS, but: A STA assumes the role of the PBSS Central Point (PCP) Only the PCP transmits beacon frames Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al.

15 The Beacon Interval (BI) structure
May 2010 The Beacon Interval (BI) structure Beacon time (BT): An access period during which one or more mmWave Beacon frames is transmitted Association beamforming training (A-BFT): An access period during which beamforming training is performed with a PCP or AP Announcement time (AT): A request-response based management access period during which a PCP or AP delivers non-MSDUs and provides access opportunities for STAs to return non-MSDUs Data transfer time (DTT): An access period during which frame exchanges are performed between STAs. The DTT is comprised of contention-based periods (CBPs) and service periods (SPs) Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al.

16 May 2010 Channel access Channel access is coordinated using a schedule, which is delivered by the PCP/AP to non-PCP/non-AP STAs STAs are permitted to transmit data frames during contention-based periods (CBPs) and service periods (SPs) Access during CBPs is based on EDCA fine-tuned for directional access Access during SPs is reserved to specific STAs as announced in the schedule or granted by the PCP/AP Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al.

17 Fast session transfer (FST) support through multi-band operation
<month year> doc.: IEEE <doc#> May 2010 Fast session transfer (FST) support through multi-band operation Enables transition of communication of STAs from any band/channel to any other band/channel in which is allowed to operate Supports both simultaneous and non-simultaneous operation Supports both transparent and non-transparent FST In transparent FST, a STA uses the MAC same address in both bands/channels involved in the FST In non-transparent FST, the MAC addresses are different Several improvements to speed-up the FST switching time such as transparent FST, security key establishment prior to FST, TS operation over multiple bands, and Block Ack operation over multiple bands Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al. <author>, <company>

18 doc.: IEEE 802.15-<doc#>
<month year> doc.: IEEE <doc#> May 2010 Beamforming (BF) A unified and flexible BF protocol is proposed that can be tuned to simple, low power devices as well as complex devices Same protocol is used for PCP/AP-to-STA beamforming and STA-to-STA beamforming BF comprised of two independent phases: sector level sweep (SLS) phase and beam refinement protocol (BRP) phase SLS: enables communication at the control PHY rate (MCS0), and typically only provides transmit training BRP: enables receiver training and iterative refinement of the AWV of both transmitter and receiver Support for beam tracking during data communication Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al. <author>, <company>

19 BF training examples May 2010 Two phased arrays
Two transmit sector sweeps followed by a beam refinement During a transmit sector sweep, the receiver may be using a quasi-omni receive pattern Initiator has a phased array, responder has a single antenna During the receive sector sweep, the responder transmit a sector sweep many times from its single antenna. The initiator switches receive pattern every packet. Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al.

20 Coexistence with other 60GHz systems
<month year> doc.: IEEE <doc#> May 2010 Coexistence with other 60GHz systems Proposal enables fair sharing of resources with 15.3c The same channelization as other 60GHz systems is used, and the same SC chip rate as that of 15.3c CMS is adopted As required in the TGad EVM ( /296r16), an AP should not start a BSS where the signal level is above a threshold or upon detecting a 15.3c CMS preamble at >= -60 dBm In a/n, MCS 0 (BPSK, R=1/2) receive sensitivity is -82dBm and non detection level is -62 dBm → 20 dB difference In 60GHz, SC MCS 1 receive sensitivity is -68 dBm → 8 dB difference with respect to required c CMS preamble detection threshold Requirement of detection of c CMS preamble is 12dB more stringent than a/n and non detection! STAs can perform channel measurements and report results to AP/PCP Several mechanisms can be used to mitigate interference with other 60GHz systems, including: Change operating channel, beamforming, reduce transmit power, move the BT (and thus the BI) in case of an AP or PCP, change or request the change of scheduled SPs and CBPs in the BI, defer transmission for a later time Carlos Cordeiro, Intel /Gal Basson, Wilocity/et. al. <author>, <company>
