Abstract
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an aspect, an apparatus may be configured to determine whether to switch to an active mode, a power save mode, or a TWT power save mode. During the TWT power save mode, the apparatus may enter an awake state during TWT service periods and may enter a doze state outside of the TWT service periods. The apparatus may transmit a message to a second wireless device based on the determination.
Claims30
A method of wireless communication by a first wireless device, comprising:
- receiving, from a second wireless device, a first message that indicates an intention of the second wireless device to switch from a first operating mode to a second operating mode, wherein the first operating mode is one of an active mode, a power save mode, or a target wake time (TWT) power save mode, wherein the second operating mode is one of the active mode, the power save mode, or the TWT power save mode, wherein the first operating mode is different from the second operating mode and the intention to switch from the first operating mode to the second operating mode includes the intention to transition to or from the TWT power save mode, and wherein the second wireless device is configured to enter an awake state during TWT service periods and enter a doze state outside of the TWT service periods when configured to operate in the TWT power save mode;
- and
- transmitting, to the second wireless device, an acknowledgment that indicates that the first wireless device received the first message.
A first wireless device comprising:
- means for receiving, from a second wireless device, a first message that indicates an intention of the second wireless device to switch from a first operating mode to a second operating mode, wherein the first operating mode is one of an active mode, a power save mode, or a target wake time (TWT) power save mode, wherein the second operating mode is one of the active mode, the power save mode, or the TWT power save mode, wherein the first operating mode is different from the second operating mode and the intention to switch from the first operating mode to the second operating mode includes the intention to transition to or from the TWT power save mode, and wherein the second wireless device is configured to enter an awake state during TWT service periods and enter a doze state outside of the TWT service periods when configured to operate in the TWT power save mode;
- and
- means for transmitting, to the second wireless device, an acknowledgment that indicates that the first wireless device received the first message.
A first wireless device comprising:
- a memory;
- and
- at least one processor coupled to the memory, wherein the at least one processor is configured to:
- receive, from a second wireless device, a first message that indicates an intention of the second wireless device to switch from a first operating mode to a second operating mode, wherein the first operating mode is one of an active mode, a power save mode, or a target wake time (TWT) power save mode, wherein the second operating mode is one of the active mode, the power save mode, or the TWT power save mode, wherein the first operating mode is different from the second operating mode and the intention to switch from the first operating mode to the second operating mode includes the intention to transition to or from the TWT power save mode, and wherein the second wireless device is configured to enter an awake state during TWT service periods and enter a doze state outside of the TWT service periods when configured to operate in the TWT power save mode;
- and
- transmit, to the second wireless device, an acknowledgment that indicates that the first wireless device received the first message.
3 more elements
A non-transitory computer-readable medium having code stored thereon that is executable by at least one processor of a first wireless device, wherein the code comprises:
- instructions for receiving a first message from a second wireless device that indicates an intention of the second wireless device to switch from a first operating mode to a second operating mode, wherein the first operating mode that is one of an active mode, a power save mode, or a target wake time (TWT) power save mode, wherein the second operating mode is one of the active mode, the power save mode, or the TWT power save mode, wherein the first operating mode is different from the second operating mode and the intention to switch from the first operating mode to the second operating mode includes the intention to transition to or from the TWT power save mode, wherein the second wireless device is configured to enter an awake state during TWT service periods and enter a doze state outside of the TWT service periods when configured to operate in the TWT power save mode;
- and
- instructions for transmitting to the second wireless device an acknowledgment that indicates that the first wireless device received the first message.
