Apparatuses, methods, and computer-readable medium for communication in a wireless local area network

A method of wireless communication by a station (STA), the method comprising:

• receiving a first downlink (DL) communication that (1) includes information for identifying a plurality of STAs and (2) is configured to cause each STA of the plurality of STAs to transmit a first uplink (UL) communication configured to protect a second DL communication comprising a multiuser transmission to the plurality of STAs;
• and
• after transmitting the first UL communication, (1) receiving the second DL communication comprising the multiuser transmission, the multiuser transmission comprising a packet for the plurality of STAs and comprising at least a field useable by at least the STA, (2) based at least in part on at least the field included in the packet, determining (A) a total number of space-time streams (STSs) included in the packet and (B) a set of values indicating a number of STSs for each of at least two STAs of the plurality of STAs, wherein at least one of the values in the set of values comprises a value equal to (i) the total number of STSs included in the packet minus (ii) one or more other values in the set of values, (3) while processing the packet, considering (A) a user position (UP) value of the STA and (B) a number of STSs allocated to one or more STAs having one or more UP values different from the UP value of the STA, wherein (i) a first number of STSs intended for a first STA comprises a first value, (ii) one or more other numbers of STSs intended for one or more other STAs different from the first STA comprise one or more other values, and (iii) the first value of the first number of STSs intended for the first STA is greater than or equal to each of the one or more other values of the one or more other numbers of STSs intended for the one or more other STAs different from the first STA, (4) receiving a third DL communication that (A) is configured to trigger UL transmission by two or more STAs in response to receiving the third DL communication and (B) includes a request that solicits an acknowledgement message from each of the two or more STAs, and (5) after the third DL communication, transmitting a second UL communication comprising a message indicating whether the third DL communication was successfully received by at least the STA, the message transmitted by at least the STA even if at least one other STA of the two or more STAs is transmitting another message indicating whether the third DL communication was successfully received by the at least one other STA of the two or more STAs.

An access point (AP) for wireless communication, the AP comprising:

• at least one transceiver;
• and
• one or more processors configured to initiate one or more communications utilizing the at least one transceiver, the one or more communications comprising:
• transmitting a first downlink (DL) communication that (1) includes information for identifying a plurality of stations (STAs) and (2) is configured to cause each STA of the plurality of STAs to transmit a first uplink (UL) communication configured to protect a second DL communication comprising a multiuser transmission to the plurality of STAs;
• and
• after receiving the first UL communication, (1) transmitting the second DL communication comprising the multiuser transmission to the plurality of STAs, the multiuser transmission comprising a packet for the plurality of STAs and comprising at least a field useable by at least one STA, wherein the transmitting the second DL communication results in the at least one STA (A) based at least in part on at least the field included in the packet, determining (i) a total number of space-time streams (STSs) included in the packet and (ii) a set of values indicating a number of STSs for each of at least two STAs of the plurality of STAs, wherein at least one of the values in the set of values comprises a value equal to (i) the total number of STSs included in the packet minus (ii) one or more other values in the set of values, and (B) while processing the packet, considering (i) a user position (UP) value of the at least one STA and (ii) a number of STSs allocated to one or more STAs having one or more UP values different from the UP value of the at least one STA, wherein (i) a first number of STSs intended for a first STA comprises a first value, (ii) one or more other numbers of STSs intended for one or more other STAs different from the first STA comprise one or more other values, and (iii) the first value of the first number of STSs intended for the first STA is greater than or equal to each of the one or more other values of the one or more other numbers of STSs intended for the one or more other STAs different from the first STA, (2) transmitting a third DL communication that (A) is configured to trigger UL transmission by two or more STAs in response to receiving the third DL communication and (B) includes a request that solicits an acknowledgement message from each of the two or more STAs, and (3) after the third DL communication, receiving at least a second UL communication comprising a message indicating whether the third DL communication was successfully received by at least the at least one STA, the message from the at least one STA being received by the AP even if at least one other STA of the two or more STAs transmits another message indicating whether the third DL communication was successfully received by the at least one other STA of the two or more STAs.
