Active base station role in user equipment discovery for user equipment cooperation

A method of wireless communication comprising:

• receiving, by a base station (BS) from a candidate cooperative user equipment (UE), a first information set associated with the candidate cooperative UE,
• wherein the first information set comprises at least UE availability information of the candidate cooperative UE, wherein the UE availability information comprises:
• discontinuous reception (DRX) information of the candidate cooperative UE, and
• an indication of a time slot during which the candidate cooperative UE is available for cooperation, the time slot comprising a time stamp and a window length during which the candidate cooperative UE is available for cooperation;
• communicating, by the BS to a target UE, at least a portion of the first information set;
• and
• receiving, by the BS from the target UE, a cooperative UE update request based on the at least a portion of the first information set.

A user equipment (UE) comprising:

• a transceiver configured to:
• receive, from a base station (BS), a first information set associated with a candidate cooperative UE,
• wherein the first information set comprises UE availability information of the candidate cooperative UE, wherein the UE availability information comprises:
• discontinuous reception (DRX) information of the candidate cooperative UE, and
• an indication of a time slot during which the candidate cooperative UE is available for cooperation, the time slot comprising a time stamp and a window length during which the candidate cooperative UE is available for cooperation;
• and
• a processor configured to:
• discover the candidate cooperative UE based on the first information set;
• and
• connect to the candidate cooperative UE,
• wherein the transceiver is further configured to communicate with the BS through the candidate cooperative UE.

• an indication of a time slot during which the candidate cooperative UE is available for cooperation, the time slot comprising a time stamp and a window length during which the candidate cooperative UE is available for cooperation;
• communicate, to a target UE, at least a portion of the first information set;
• and
• receive, from the target UE, a cooperative UE update request based on the at least a portion of the first information set.
