Apparatuses, methods, and computer-readable medium for communication in a wireless local area network
View Patent ↗Many aspects pertaining to various apparatuses, methods, and computer-readable medium are described herein. Some aspects pertain to wireless communication between various apparatuses, which may include one or more access points (APs) and/or one or more stations (STAs). The one or more APs and/or one or more STAs may have one or more radios. Some aspects pertain to various features related to such one or more radios. Some aspects pertain to certain technologies related to uplink (UL) communication(s) and/or downlink (DL) communication(s). The written description and appended drawings provide detailed descriptions regarding these and many other aspects.
1. A method of wireless communication by a station (STA), the method comprising:
determining to perform concerted communication, wherein the concerted communication comprises two or more apparatuses transmitting the same information at the same time or time period in accordance with a setup protocol, wherein the setup protocol comprises negotiating at least (1) how many links or channels to be enabled by the STA, (2) which radios of the STA to use for that quantity of links or channels, and (3) which types of information will be communicated in each of those links or channels;
receiving a plurality of frames, the plurality of frames comprising: (1) a first uplink (UL) transmission request (ULTR) configured to trigger UL transmission by two or more STAs, (2) a field indicating resource allocation for one or more UL transmissions triggered by the ULTR, (3) an indication of a transmission opportunity (TXOP) duration for setting at least one network allocation vector (NAV) of at least the STA, and (4) information for determining use of a process that sets one or more times for at least the STA to access transmission medium; and
entering a doze mode after at least receiving or transmitting of a message comprising scheduling information, remaining in the doze mode until a time corresponding to the scheduling information included in the message, and subsequently receiving a second uplink (UL) transmission request (ULTR) that (1) is configured to trigger UL transmission by a plurality of STAs within a period of time after receiving the second ULTR and (2) comprises (A) an allocation of at least one resource for each UL transmission by the plurality of STAs and (B) a field common to the plurality of STAs, the field common to the plurality of STAs (i) indicating a duration of at least a portion of UL transmission and (ii) indicating whether communication of the second ULTR will be followed by communication of a third ULTR, the third ULTR configured to trigger another UL transmission within a period of time after communication of the third ULTR.
2. A station (STA) for wireless communication, the STA comprising:
at least one transceiver; and
one or more processors configured to:
determine to perform concerted communication, wherein the concerted communication comprises two or more apparatuses transmitting the same information at the same time or time period in accordance with a setup protocol, wherein the setup protocol comprises negotiating at least (1) how many links or channels to be enabled by the STA, (2) which radios of the STA to use for that quantity of links or channels, and (3) which types of information will be communicated in each of those links or channels;
receive a plurality of frames, the plurality of frames comprising: (1) a first uplink (UL) transmission request (ULTR) configured to trigger UL transmission by two or more STAs, (2) a field indicating resource allocation for one or more UL transmissions triggered by the ULTR, (3) an indication of a transmission opportunity (TXOP) duration for setting at least one network allocation vector (NAV) of at least the STA, and (4) information for determining use of a process that sets one or more times for at least the STA to access transmission medium; and
enter a doze mode after at least receiving or transmitting of a message comprising scheduling information, remaining in the doze mode until a time corresponding to the scheduling information included in the message, and subsequently receiving a second uplink (UL) transmission request (ULTR) that (1) is configured to trigger UL transmission by a plurality of STAs within a period of time after receiving the second ULTR and (2) comprises (A) an allocation of at least one resource for each UL transmission by the plurality of STAs and (B) a field common to the plurality of STAs, the field common to the plurality of STAs (i) indicating a duration of at least a portion of UL transmission and (ii) indicating whether communication of the second ULTR will be followed by communication of a third ULTR, the third ULTR configured to trigger another UL transmission within a period of time after communication of the third ULTR.
3. A method of wireless communication by an access point (AP), the method comprising:
determining to perform concerted communication, wherein the concerted communication comprises two or more apparatuses transmitting the same information at the same time or time period in accordance with a setup protocol, wherein the setup protocol comprises negotiating at least (1) how many links or channels to be enabled by one or more stations (STAs), (2) which radios of the one or more STAs is/are to use that quantity of links or channels, and (3) which types of information will be communicated in each of those links or channels; and
transmitting a plurality of frames, the plurality of frames comprising: (1) a first uplink (UL) transmission request (ULTR) configured to trigger UL transmission by two or more STAs, (2) a field indicating resource allocation for one or more UL transmissions triggered by the ULTR, (3) an indication of a transmission opportunity (TXOP) duration for setting at least one network allocation vector (NAV) of at least the one or more STAs, and (4) information for determining use of a process that sets one or more times for at least the one or more STAs to access transmission medium,
wherein at least the one or more STAs enter a doze mode after at least receiving or transmitting a message comprising scheduling information, remain in the doze mode until a time corresponding to the scheduling information included in the message, and subsequently receive a second uplink (UL) transmission request (ULTR) that (1) is configured to trigger UL transmission by a plurality of STAs within a period of time after receiving the second ULTR and (2) comprises (A) an allocation of at least one resource for each UL transmission by the plurality of STAs and (B) a field common to the plurality of STAs, the field common to the plurality of STAs (i) indicating a duration of at least a portion of UL transmission and (ii) indicating whether communication of the second ULTR will be followed by communication of a third ULTR, the third ULTR configured to trigger another UL transmission within a period of time after communication of the third ULTR.
