Abstract
Certain aspects of the present disclosure generally provide methods and apparatus for enhanced discovery procedures in peer-to-peer (P2P) wireless local area networks (WLANs). With these procedures, discovery duration may be decreased, battery power consumption may be reduced during discovery, provided services may be ascertained during the device discovery phase without performing a separate service discovery phase, and/or the discovery range may be extended in an effort to discover a greater number of devices.
Claims58
A first apparatus for wireless communications, comprising:
- a processing system configured to:
- wake up the first apparatus at a particular time for a discovery period;
- and
- discover one or more second apparatuses during the discovery period, wherein the discovery period is common among the first and second apparatuses;
- and
- a transceiver configured to transmit, during the discovery period, information about a service provided by or an application available at the first apparatus and receive a response from at least one of the second apparatuses based on the information and to communicate directly with at least one discovered second apparatus independent of using a central node.
A method performed by an apparatus for wireless communications, comprising:
- waking up at a particular time for a discovery period;
- discovering one or more other apparatuses during the discovery period, wherein the discovery period is common among the other apparatuses;
- transmitting, during the discovery period, information about a service provided by or an application available at the apparatus and receiving a response from at least one of the other apparatuses based on the information;
- and
- communicating directly with at least one discovered other apparatus independent of using a central node.
A first apparatus for wireless communications, comprising:
- means for waking up the first apparatus at a particular time for a discovery period;
- means for discovering one or more second apparatuses during the discovery period, wherein the discovery period is common among the first and second apparatuses;
- means for transmitting, during the discovery period, information about a service provided by or an application available at the first apparatus and receiving a response from at least one of the second apparatuses based on the information
- means for communicating directly with at least one discovered second apparatus independent of using a central node.
A computer-program product for wireless communications, comprising a computer-readable medium comprising instructions executable to:
- wake up an apparatus at a particular time for a discovery period;
- discover one or more other apparatuses during the discovery period, wherein the discovery period is common among the other apparatuses;
- transmit, during the discovery period, information about a service provided by or an application available at the apparatus and receive a response from at least one of the other apparatuses based on the information;
- and
- communicate directly with at least one discovered other apparatus independent of using a central node.
A wireless node, comprising:
- at least one antenna;
- a processing system configured to:
- wake up the wireless node at a particular time for a discovery period;
- discover one or more apparatuses during the discovery period, wherein the discovery period is common among the apparatuses;
- and
- a transceiver configured to transmit, during the discovery period, information about a service provided by or an application available at the first apparatus and receive a response from at least one of the second apparatuses based on the information and to communicate directly with at least one discovered apparatus, via the at least one antenna, independent of using a central node.
A first apparatus for wireless communications, comprising:
- a receiver configured to receive information about a second apparatus for discovery, wherein the information comprises information about a service provided by or an application available at the second apparatus;
- a processing system configured to discover the second apparatus based on the information;
- and
- a transmitter configured to communicate directly with the second apparatus discovered based on the information independent of using a central node.
A method for wireless communications, comprising:
- receiving information about an apparatus for discovery, wherein the information comprises information about a service provided by or an application available at the apparatus;
- discovering the apparatus based on the information;
- and
- communicating directly with the apparatus discovered based on the information independent of using a central node.
A first apparatus for wireless communications, comprising:
- means for receiving information about a second apparatus for discovery, wherein the information comprises information about a service provided by or an application available at the second apparatus;
- means for discovering the second apparatus based on the information;
- and
- means for communicating directly with the second apparatus discovered based on the information independent of using a central node.
A computer-program product for wireless communications, comprising a computer-readable medium comprising instructions executable to:
- receive information about an apparatus for discovery, wherein the information comprises information about a service provided by or an application available at the apparatus;
- discover the apparatus based on the information;
- and
- communicate directly with the apparatus discovered based on the information independent of using a central node.
A wireless node, comprising:
- at least one antenna;
- a receiver configured to receive, via the at least one antenna, information about an apparatus for discovery, wherein the information comprises information about a service provided by or an application available at the apparatus;
- a processing system configured to discover the apparatus based on the information;
- and
- a transmitter configured to communicate directly with the apparatus discovered based on the information independent of using a central node.
