At least one station (STA) for wireless communication, the at least one STA comprising:
- a first antenna;
- a second antenna;
- and
- one or more processors configured to:
- perform concerted communication, the concerted communication comprising:
- (1) time-multiplexed communication comprising use of the first antenna of the at least one STA to communicate a first packet during a first time utilizing a first frequency range and use of the second antenna of the at least one STA to communicate a second packet during a second time utilizing a second frequency range, the second time occurring after the first time, the second packet different from the first packet, the second frequency different from the first frequency, and (2) using the first antenna of the at least one STA for a first uplink (UL) communication and a first downlink (DL) communication utilizing the first frequency range while concurrently using the second antenna of the at least one STA for a second UL communication and a second DL communication utilizing the second frequency range different from the first frequency range;
- during the concerted communication, receive at least one DL data packet comprising a preamble
- and first characteristics, the first characteristics comprising:
- a first portion at least in part modulated by a first modulation scheme and comprising a first length and first information;
- and
- a second portion at least in part modulated by a second modulation scheme and comprising at least (1) a second length same as the first length, (2) second information that is (A) at least in part the same as the first information and (B) at least in part different from the first information, or (3) a third portion at least comprising (A) a length different from the first length and the second length and (B) information indicating at least (i) a duration of a transmission opportunity, (ii) a modality of wireless communication of the at least one DL data packet, (iii) a format or type of the at least one DL data packet, or (iv) at least an identifier of a basic service set or an indication that the at least one DL data packet is an UL communication or a DL communication;
- and
- use the preamble of the at least one DL data packet to determine that the at least one DL data packet comprises the second configuration rather than the first configuration when the at least one DL data packet comprises second characteristics, the second characteristics lacking at least the first portion or the second portion.
