Abstract
In a wireless local area network system, a non-AP multi-link device (MLD) can transmit transmission power information enabling links in an NSTR relationship to operate as STR and information about a PPDU bandwidth, and operate as STR in the links in the NSTR relationship under a specific condition, on the basis thereof.
Claims16
A method in a wireless LAN system, the method comprising:
- generating, by a non point (non-AP) station (STA) multi-link device (MLD) including a first STA operating on a first link and a second STA operating on a second link, simultaneous transmit and receive (STR) information for the first and second links to operate based on a simultaneous transmit and recieve (STR) operation under a pre-defined condition,
- wherein first link and the second link belong to a pre-defined link pair to a non-simultaneous transmit and receive (NSTR) operation,
- wherein the STR information includes information related to transmission power and a bandwidth of a physical protocol data unit (PPDU);
- and
- transmitting, by the non-AP STA MLD, a PPDU including the STR information to an AP MLD.
2 more elements
A non-access point (non-AP) station (STA) multi-link device (MLD) in a wireless LAN system, comprising:
- a first STA operating on a first link:
- a second STA operating on a second link, wherein the first link and the second link belong to a pre-defined link pair related to a non-simultaneous transmit and receive (NSTR) operation,
- at least one processor coupled to the first STA and the second STA,
- wherein the processor is adapted to:
- generate simultaneous transmit and receive (STR) information for the first and second links to operate based on a simultaneous transmit and recieve (STR) operation under a pre-defined condition,
- wherein the STR information includes information related to transmission power and a bandwidth of a physical protocol data unit (PPDU);
- and
- transmit a PPDU including the STR information to an AP MLD.
5 more elements
A method in a wireless LAN system, the method comprising:
- receiving, by an access point (AP) station (STA) multi-link device (MLD) including a first AP STA operating on a first link and a second AP STA operating on a second link, a physical protocol data unit (PPDU) including simultaneous transmit and receive (STR) information for the first and second links to operate based on a simultaneous transmit and recive (STR) operation under a pre-defined conditions, wherein the first link and the second link belong to a pre-defined link pair related to a non-simultaneous transmit and receive (NSTR) operations, wherein the STR information includes information related to transmission power and a bandwidth of the PPDU;
- and
- decoding, by the AP MLD, the PPDU including the STR information.
