A method for power saving in a wireless local area network. The method according to one embodiment includes acquiring, by a wireless device, a transmission opportunity (TXOP); and receiving a signal field from the transmitting device. A group identifier indicates recipients, a number indicator indicates spatial streams, and a power saving indicator indicates that the transmitting device is allowed to enter a doze state during the TXOP. The method according to the embodiment further includes determining, by the wireless device, whether a first condition or a second condition is satisfied. The first condition is satisfied if the power saving indicator indicates an allowance, the wireless device is a recipient indicated by the group identifier, and the number of spatial streams is equal to zero. The second condition is satisfied if the power saving indicator indicates an allowance, and the wireless device is not a recipient indicated by the group identifier. |

1. A method for power saving in a wireless local area network, the method comprising:
acquiring, by a wireless device, a transmission opportunity (TXOP) from a transmitting device; receiving, by the wireless device, a signal field from the transmitting device, the signal field including a group identifier, a number indicator, and a power saving indicator, the group identifier indicating a group of recipients, the number indicator indicating a number of spatial streams for a corresponding recipient, the power saving indicator indicating that the transmitting device is allowed to enter a doze state during the TXOP; determining, by the wireless device, whether a first condition or a second condition is satisfied; and entering, by the wireless device, the doze state until the end of the TXOP if the first condition or the second condition is satisfied, wherein the first condition is satisfied if the power saving indicator indicates an allowance of entering the doze state, the wireless device is a recipient indicated by the group identifier, and the number of spatial streams to be received by the wireless device is equal to zero, and wherein the second condition is satisfied if the power saving indicator indicates an allowance of entering the doze state, and the wireless device is not a recipient indicated by the group identifier. |
