在本文中，我们提出了遵循IEEE 802.15.3C 60GHz 60GHz无线个人区域网络（60GHz WPAN）的IEEE 802.15.3C标准的指南，在媒体访问控制（MAC）层中实现了可行的波束形成（BF）方案。提出的BF靶标最小化BF设置时间并减轻60GHz WPAN系统的高路径损失。它基于设计的多分辨率代码簿，该代码簿生成了不同的半功率光束宽度（HPBWS）的三种模式：Quasi-OMNI模式，扇区和光束。这三种模式用于BF协议的三个阶段，即设备到设备（Dev-to-dev）链接，扇区级别搜索和梁级搜索。所有这三个阶段都可以在一个超级帧中完成，这可以最大程度地减少BF设置期间对其他系统的潜在干扰。在本文中，我们将显示一些示例代码手册，并提供BF过程的详细信息。仿真结果表明，与详尽的搜索协议相比，建议的BF协议的设置时间高达2％。提出的BF是一个完整的设计，它重新使用IEEE 802.15.3C中指定的命令，完全符合标准；因此，IEEE 802.15.3C已采用它作为可选功能，以实现WPAN系统中每秒（Gbps）通信。
In this paper, we propose a feasible beamforming (BF) scheme realized in media access control (MAC) layer following the guidelines of the IEEE 802.15.3c criteria for millimeter-wave 60GHz wireless personal area networks (60GHz WPANs). The proposed BF targets to minimize the BF set-up time and mitigates the high path loss of 60GHz WPAN systems. It is based on designed multi-resolution codebooks, which generate three kinds of patterns of different half power beam widths (HPBWs): quasi-omni pattern, sector and beam. These three kinds of patterns are employed in the three stages of the BF protocol, namely device-to-device (DEV-to-DEV) linking, sector-level searching and beam-level searching. All the three stages can be completed within one superframe, which minimizes the potential interference to other systems during BF set-up period. In this paper, we show some example codebooks and provide the details of BF procedure. Simulation results show that the setup time of the proposed BF protocol is as small as 2% when compared to the exhaustive searching protocol. The proposed BF is a complete design, it re-uses commands specified in IEEE 802.15.3c, completely compliant to the standard; It has thus been adopted by IEEE 802.15.3c as an optional functionality to realize Giga-bit-per-second (Gbps) communication in WPAN Systems.
