Claims42
A method for wireless communications performed by an apparatus, comprising:
- receiving, from a second apparatus, a frame comprising a first field comprising a first plurality of subfields, wherein:
- each subfield of the first plurality of subfields is associated with receiving a different respective number of spatial streams, and
- each subfield of the first plurality of subfields comprises bits indicating a maximum modulation and coding scheme (MCS) supported by the second apparatus for receiving the respective number of spatial streams associated with the respective subfield;
- selecting an MCS for communication to the second apparatus based at least in part on the first field;
- and
- transmitting data to the second apparatus according to the selected MCS.
