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.
Claims24
A method for operating a user equipment, the method comprising:
- wirelessly receiving from multiple transmission points, by the user equipment, a plurality of convergence protocol packets of a single bearer, each of the convergence protocol packets comprising a respective convergence protocol sequencing number,
- a first group of the convergence protocol packets being received by the user equipment from a first radio or link control protocol entity on a first transmission point, and
- a second group of the convergence protocol packets being received by the user equipment from a second radio or link control protocol entity on a second transmission point;
- ordering, by the user equipment, the first and second groups of convergence protocol packets according to the respective convergence protocol sequencing numbers of the convergence protocol packets;
- providing the ordered convergence protocol packets to a higher network layer entity of the user equipment;
- and
- wirelessly transmitting, by the user equipment, a convergence protocol status report indicating whether one or more packets of the first and second groups of the convergence protocol packets of the single bearer are lost.
A user equipment comprising:
- a non-transitory memory storage, in the user equipment, comprising instructions;
- and
- one or more processors, in the user equipment and in communication with the memory storage, wherein the one or more processors execute the instructions to:
- wirelessly receive, from multiple transmission points, a plurality of convergence protocol packets of a single bearer, each of the convergence protocol packets comprising a respective convergence protocol sequencing number,
- a first group of the convergence protocol packets being received by the user equipment from a first radio or link control protocol entity on a first transmission point;
- and
- a second group of the convergence protocol packets being received by the user equipment from a second radio or link control protocol entity on a second transmission point;
- order, by the user equipment, the first and second groups of convergence protocol packets according to the respective convergence protocol sequencing numbers of the convergence protocol packets;
- provide the ordered convergence protocol packets to a higher network layer entity of the user equipment;
- and
- wirelessly transmit a convergence protocol status report indicating whether one or more packets of the first and second groups of the convergence protocol packets of the single bearer are lost.
