BARRIAC, Gwendolyn Denise; 5775 Morehouse [Continued on next page] (54) Title: METHODS AND APPARATUS FOR SELECTING ENHANCED DISTRIBUTED CHANNEL ACCESS PARAMET- ERS FOR DIFFERENT STATIONS (57) : In some aspects, a method for configuring channel access parameters in a wireless communication system includes determining, at an access point, an en- hanced distributed channel access (EDCA) parameter for a first subset of stations of a plurality of stations, the first subset of stations capable of transmitting multi-user uplink transmissions. The method further includes generating an information element including the EDCA parameter. The method further includes transmitting the information ele- ment such that the information element is decodable by the first subset of stations and not by a second subset of stations of the plurality of stations. 100 --- i t 110d — 108a 106a K-110a TV STA HEWC 156b W O 20 1712395 / 2 Al 106d \ (1 \( -102 ROUTER STA HEWC 156d LAPTOP STA HEWC 156c 108c 104 I I 108b ACCESS POINT AP HEWC 154 FIG. 1 CELL PHONE STA HEWC 156a 108d 106c WO 2017/123952 All#1101MOHIMIIMMEMOMOHOMMHEIHRHOE# (84) Designated States (unless otherwise indicated, for every kind of regional protection available): ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
