Transmission parameters for very high throughput transmission

摘要

Transmission parameters are determined for communication between apparatuses. These transmission parameters may specify, for example, a number of spatial streams, a bandwidth, and a transmission rate. Based on the determined parameters, a table of a set of tables comprising transmission parameters is identified and an index from the table is determined. Rate information is then sent in a frame from one of the apparatuses to the other. The rate information comprises several fields indicative of the index, the number of spatial streams, and bandwidth. The apparatus that receives the rate information may then use this information to identify the table and obtain transmission parameters from the table.

1. A method of communication, comprising:
determining transmission parameters for communication with an apparatus, wherein the determined transmission parameters comprise a number of spatial streams, a bandwidth, and a modulation and coding scheme; identifying a table of a set of tables of transmission parameters, wherein the identification of the table is based on the number of spatial streams and the bandwidth; determining an index from the identified table, wherein the determination of the index is based on the modulation and coding scheme; and transmitting a frame to the apparatus, wherein the frame contains indications of: the index, the number of spatial streams, and the bandwidth.
