    Abstract: Embodiments of this application provide a modulation method and apparatus. The method includes: receiving a code word sequence, where each code word includes N bits, and the code word sequence includes at least a first code word; mapping the code word sequence into M sequences, where each sequence includes N/M bits from the first code word; mapping the M sequences into a symbol sequence, where each symbol is corresponding to M bits, the M bits are respectively from the M sequences, first bits corresponding to N/M first-type symbols are from the first code word, and second bits corresponding to N/M second-type symbols are from the first code word. Thus a signal-to-noise ratio requirement during higher order modulation lowered.

    Abstract: Provided in the embodiments of the present invention are a method, a device and a system for setting a weight feedback granularity, relating to communication technologies, which solve the problem that a beamforming transmitting end can not control a beamforming weight feedback granularity. The method comprises: receiving a null data packet announcement (NDPA) frame comprising a weight feedback granularity requirement value transmitted by the beamforming transmitting end; receiving a null data packet (NDP) frame transmitted by the beamforming transmitting end, and measuring the beamforming weight by using the weight feedback granularity requirement value as a granularity; and transmitting a very high throughput compressed beamforming (VCBF) frame to the beamforming transmitting end, wherein the very high throughput compressed beamforming (VCBF) frame comprises the beamforming weight using the weight feedback granularity requirement value as the granularity. The embodiments of the present inventions are suitable for setting a weight feedback granularity.

    Abstract translation: 在本发明的实施例中提供了一种用于设置与通信技术有关的权重反馈粒度的方法，装置和系统，其解决了波束成形发送端不能控制波束成形权重反馈粒度的问题。 该方法包括：接收包括由波束成形发送端发送的加权反馈粒度要求值的零数据分组公告（NDPA）帧; 接收由波束成形发送端发送的空数据分组（NDP）帧，并通过使用权重反馈粒度要求值作为粒度来测量波束成形权重; 以及将非常高吞吐量的压缩波束成形（VCBF）帧发送到波束成形发送端，其中非常高吞吐量的压缩波束形成（VCBF）帧包括使用权重反馈粒度要求值作为粒度的波束成形权重。 本发明的实施例适合于设置重量反馈粒度。
