Abstract
A system and method for information delivery with multiple point transmission are provided. A method for detecting lost packets is provided. The method includes initiating a timer for a received packet at a receiving transmission point, where the timer is set according to a time value associated with the received packet. The method also includes determining that a delivery of the received packet has failed according to the timer elapsing, and transmitting a lost packet report to a primary transmission point that distributed the received packet to the receiving transmission point.
Claims30
A method for reporting delivery status of a plurality of packet data convergence protocol (PDCP) packets of a PDCP stream split from a single bearer, the method comprising:
- initiating, by a receiving transmission point, a threshold evaluator for a transmission condition of the PDCP stream split from the single bearer;
- determining, by the receiving transmission point in accordance with the threshold evaluator, the delivery status of the plurality of PDCP packets of the PDCP stream split from the single bearer;
- and
- transmitting, by the receiving transmission point, a report of the delivery status to a primary transmission point that distributed the plurality of PDCP packets to the receiving transmission point.
A receiving transmission point comprising:
- a processor configured to:
- initiate a threshold evaluator for a transmission condition of a packet data convergence protocol (PDCP) stream split from a single bearer;
- and
- determine, in accordance with the threshold evaluator, a delivery status of a plurality of PDCP packets of the PDCP stream split from the single bearer;
- and
- a transmitter operatively coupled to the processor and configured to transmit a report of the delivery status to a primary transmission point that distributed the plurality of PDCP packets to the receiving transmission point.
