Abstract:
(EN) A method for performing an operation in accordance with a PS mode in a wireless LAN system comprises the steps of: performing a receiving operation for an EDMG MU PPDU, wherein the EDMG MU PPDU includes a preamble and a plurality of A-MPDUs having the same length transmitted on an overlapped time resource, the preamble includes first order information on a transmission order of a first block ACK frame for a first A-MPDU to be transmitted to a first STA among the plurality of A-MPDUs, and the transmission order is determined according to a length of a data area included in the first A-MPDU; converting a power state of the first STA into a doze state at a first time when the reception of the first data area included in the first A-MPDU is finished, if it is determined that the transmission order of the first block ACK frame is not the first on the basis of the first order information; maintaining, as the doze state, the power state from the first time to a second time; and converting the power state into an awake state after the second time elapses.
(FR) L'invention concerne un procédé pour effectuer une opération conformément à un mode d'économie d'énergie (PS) dans un système LAN sans fil, ledit procédé comprenant les étapes consistant : à effectuer une opération de réception pour une PPDU MU de l'EDMG, la PPDU MU de l'EDMG comprenant un préambule et une pluralité de A-MPDU présentant la même longueur transmises sur une ressource temporelle de chevauchement, le préambule comprenant des premières informations d'ordre sur un ordre de transmission d'une première trame ACK de bloc pour une première A-MPDU à transmettre à une première STA parmi la pluralité de A-MPDU, et l'ordre de transmission étant déterminé en fonction d'une longueur d'une zone de données comprise dans la première A-MPDU; à convertir un état de puissance de la première STA en un état de repos à un premier instant où la réception de la première zone de données comprise dans la première A-MPDU est terminée, s'il est déterminé que l'ordre de transmission de la première trame ACK de bloc n'est pas le premier sur la base des premières informations d'ordre; à maintenir, en tant qu'état de veille, de l'état de puissance du premier instant à un second instant; et à convertir l'état de puissance en un état de veille après l'écoulement du second instant.
(KO) 무선랜 시스템에서 PS 모드에 따른 동작을 수행하는 방법은, EDMG MU PPDU에 대한 수신 동작을 수행하되, EDMG MU PPDU는 프리앰블 및 중첩된 시간 자원 상에서 송신되는 동일한 길이를 갖는 복수의 A-MPDU를 포함하고, 프리앰블은 복수의 A-MPDU 중에서 제1 STA로 송신될 제1 A-MPDU를 위한 제1 블록 ACK 프레임의 송신 순서에 대한 제1 순서 정보를 포함하고, 송신 순서는 제1 A-MPDU에 포함된 데이터 영역의 길이에 따라 결정되는, 단계; 제1 순서 정보를 기반으로 제1 블록 ACK 프레임의 송신 순서가 송신 순서가 첫 번째가 아니라고 판단될 때, 제1 A-MPDU에 포함된 제1 데이터 영역의 수신이 완료되는 제1 시점에 제1 STA의 전력 상태를 도즈 상태로 전환하는 단계; 제1 시점부터 제2 시점까지 전력 상태를 도즈 상태로 유지하는, 단계; 및 제2 시점 경과 후, 전력 상태를 어웨이크 상태로 전환하는 단계를 포함한다.
