In some implementations, a transmit opportunity (TxOP) period truncation or i, whether to update a network allocation vector (NAV) timing based on a mes- sage that includes transmitter and receiver information (such as a transmitter 405 address (TA) and a receiver address (RA)) may be determined. For example, a station may receive a contention-free end (CF-End) frame and determine a TxOP period truncation based on comparing a TA and an RA included in the CF-End frame with a TA and an RA included in an earlier received message (e.g., an RTS). Such information may be compared to other TAs or RAs asso- ciated with NAV timing values and the NAV timing may be set, reset, updated, or canceled based on the comparison. 400 = (54) = = - = _ = 420 435 \ I dte NA , = 4I5 N I pdate NAV 1 DATA — = = = - = 42' 1 pdate NAV 430 -\ 1-pddt 1 NA‘ CF END 11 11 ei IN kin © -.... co Il © ei 440 - T_ pda1 NAV Hismry 44 5 .. \,,1 1 Nate 450 Timing I NAV ei c~ntenQ ,n FIG. 4 O [Continued on next page] WO 2018/057221 Al MIDEDIMOM0101011EFIDINIRIONIHOHHOIIIMEMOIMIE TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
