BLOCK RECEIPT MECHANISM FOR ACKNOWLEDGMENT OF DL-MU DATA IN UL-MU WIRELESS COMMUNICATION SYSTEM Russian patent published in 2019 - IPC H04L1/16 H04L1/18 H04W72/04 

FIELD: physics.

SUBSTANCE: invention relates to wireless communication. First user terminal receives from the access point a protocol data unit (PPDU) of multi-user (MU) downlink mode (DL) (DL MU PPDU) corresponding to a physical layer convergence protocol (PLCP). At that, DL MU PPDU includes first protocol-specific data unit (A-MPDU) relating to medium access control (MAC) level, a flip flop of a block receipt (BA) and an acknowledgment policy which instructs the first user terminal when to transmit the BA to the access point, wherein the first A-MPDU includes a plurality of MPDUs, wherein the flip-flop BA differs from the acknowledgment policy. First user terminal transmits to the access point the first BA based on the flip-flop BA and the acknowledgment policy, wherein the first BA acknowledges one or more MPDUs from the said plurality of MPDUs.

EFFECT: technical result of the invention is enabling multiple user terminals to communicate with one access point by sharing channel resources, while achieving high throughput capabilities of transmitting data.
