Abstract
Apparatuses and methods of power save for wireless access point and multi-hop relays are disclosed. In one innovation, an apparatus comprises a memory unit configured to store latency information received from the at least one communication device and a processor operationally coupled to the memory unit and configured to retrieve the latency information from the memory unit and determine a sleep-cycle for the apparatus based on the latency information, the sleep-cycle indicating a time period when the apparatus will not receive signals and will not send signals.
Claims53
An apparatus for communicating with at least one communication device of a wireless network via a channel, comprising:
- a transceiver configured to receive latency information from the at least one communication device;
- and
- a processor operationally coupled to the transceiver, the processor configured to:
- determine an awake duration based on a first set of latency information, wherein the transceiver is further configured to communicate with the at least one communication device for the awake duration,
- determine a sleep-cycle based on the first set of latency information, the sleep-cycle to begin after expiration of the awake duration, wherein the transceiver is further configured to stop communication with the at least one communication device for the sleep-cycle, and
- update the awake duration based on a second set of latency information, the transceiver further configured to communicate with the at least one communication device for the updated awake duration.
A method of communicating between two or more communication devices via a channel, the method comprising:
- receiving latency information from a first communication device of the two or more communication devices;
- determining an awake duration based on a first set of latency information;
- communicating with the first communication device for the awake duration;
- determining a sleep-cycle based on the first set of latency information, the sleep-cycle to begin after expiration of the awake duration ending communication with the two or more communication devices during the sleep-cycle;
- updating the awake duration based on a second set of latency information;
- and
- communicating with the at least one communication device for the updated awake duration.
An apparatus for communicating with at least one communication device via a channel, comprising:
- means for communicating, the means for communicating configured to receive latency information from the at least one communication device;
- means for determining:
- an awake duration based on a first set of latency information, wherein the means for communicating is configured to communicate with the at least one communication device for the awake duration,
- a sleep-cycle based on the first set of latency information, the sleep-cycle to begin after expiration of the awake duration, wherein the means for receiving latency information is further configured to stop communication with the at least one communication device for the sleep-cycle, and
- an update to the awake duration based on a second set of latency information, the means for receiving latency information further configured to communicate with the at least one communication device for the updated awake duration.
A non-transitory computer readable media having instructions stored thereon that cause a wireless communication apparatus to perform a method of:
- receiving latency information received from at least one communication device;
- determining an awake duration based on a first set of latency information;
- communicating with the at least one communication device for the awake duration;
- determining a sleep-cycle based on the first set of latency information, the sleep-cycle to begin after expiration of the awake duration;
- ending communication with the at least one communication device during the sleep-cycle;
- updating the awake duration based on a second set of latency information;
- and
- communicating with the at least one communication device for the updated awake duration.
