Method and apparatus for contention resolution of passive endpoints

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
• cause, at least in part, scanning, by a first active endpoint having a memory tag reader, of a data channel of a memory tag of a passive endpoint that delivers memory content to one or more active endpoints, to detect a powered state of the memory tag;
• identify by the first active endpoint a second active endpoint having a memory tag reader based, at least in part, on detection of the powered state;
• generate by the first active endpoint a request to the second active endpoint for the first active endpoint to enter an active mode with respect to the memory tag;
• cause, at least in part, transmission of the request by the first active endpoint to the second active endpoint;
• receive by the first active endpoint a response from the second active endpoint to the request;
• and
• join the first active endpoint to one or more powered periods of the memory tag established with the second active endpoint based, at least in part, on the response, for communication with the memory tag to access the memory content.

A computer-readable storage medium carrying one or more sequences

• of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:
• causing, at least in part, scanning, by a first active endpoint having a memory tag reader, of a data channel of a memory tag of a passive endpoint that delivers memory content to one or more active endpoints, to detect a powered state of the memory tag;
• identifying by the first active endpoint a second active endpoint having a memory tag reader based, at least in part, on detection of the powered state;
• generating by the first active endpoint a request to the second active endpoint for the first active endpoint to enter an active mode with respect to the memory tag;
• causing, at least in part, transmission of the request by the first active endpoint to the second active endpoint;
• receiving by the first active endpoint a response from the second active endpoint to the request;
• and
• joining the first active endpoint to one or more powered periods of the memory tag established with the second active endpoint based, at least in part, on the response, for communication with the memory tag to access the memory content.
