Selective signaling information sharing for CoMP enhancement

A method of facilitating coordinated multi-point communication (CoMP) in a wireless communications network including at least a first base station (BS) and a second BS, a plurality of user equipment (UEs) being associated with the second BS, the method comprising:

• receiving, at the second BS from the first BS, a status request message requesting the second BS to report one or more types of status information, the status request message including at least one of an aggregation indicator and conditional reporting indicator, the aggregation indicator being an indicator that specifies whether the second BS is to report individual measurements or aggregated measurements to the first BS, the conditional reporting indicator being an indicator that indicates to the second BS to report measurements corresponding to the one or more types of resource status information to the first BS only when one or more first conditions are met;
• selecting one or more UEs, from among the plurality of UEs, based on the at least one of an aggregation indicator and a conditional reporting indicator;
• generating, at the second BS, a status response message based on measurements corresponding only to the selected one or more UEs;
• and
• sending the status response message from the second BS to the first BS.

A network element comprising:

• a processor, the network element being programmed such that the processor executes operations for facilitating coordinated multi-point communication (COMP) in a wireless communications network including at least a first base station (BS) and a second BS, the network element being the first BS, a plurality of user equipment (UEs) being associated with the second BS, the operations including,
• generating a status request message for requesting the second BS to report one or more types of status information, the status request message including at least one of an aggregation indicator and conditional reporting indicator, the aggregation indicator being an indicator that specifies whether the second BS is to report individual measurements or aggregated measurements to the first BS, the conditional reporting indicator being an indicator that indicates to the second BS to report measurements corresponding to the one or more types of resource status information to the first BS only when one or more first conditions are met,
• sending the status request message to the second BS, and
• receiving, from the second BS, a status response message in response to the sent status request message, the status response message including only measurements that conform to the at least one of an aggregation indicator and a conditional reporting indicator.

• receiving a status request message requesting the second BS to report to the first BS one or more types of status information, the status request message including at least one of an aggregation indicator and conditional reporting indicator, the aggregation indicator being an indicator that specifies whether the second BS is to report individual measurements or aggregated measurements to the first BS, the conditional reporting indicator being an indicator that indicates to the second BS to report measurements corresponding to the one or more types of resource status information to the first BS only when one or more first conditions are met,
• selecting one or more UEs, from among the plurality of UEs, based on the report control information,
• generating a status response message based on measurements corresponding only to the selected one or more UEs, and
• sending the status response message to the first BS.
