Abstract:
Apparatuses, methods, and computer readable media for indicating a communication and information in a signal field are disclosed. A high-efficiency wireless local area network (HEW) device comprises circuitry is disclosed. The circuitry may be configured to: generate a HEW packet comprising a legacy signal (L-SIG) field, where the L-SIG field comprises a plurality of subcarriers, and an R-L-SIG field, where the R-L-SIG field comprises a repeat of the plurality of subcarriers partitioned into a plurality of groups, and where information is encoded into one or more groups of the plurality of groups by a same modulation to each subcarrier partitioned into the corresponding group. A HEW device comprising circuitry is disclosed. The circuitry may be configured to: receive a L-SIG field; receive a R-L-SIG field; and determine whether the R-L-SIG field is a repeat of the L-SIG field with piggybacked information.
