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.
Claims36
A method for operating a primary transmission point in a multiple point transmission system, the method comprising:
- distributing a plurality of packet data convergence protocol (PDCP) layer packets of a single bearer to N transmission points for transmission to a user equipment (UE), where N is an integer value greater than or equal to two, and wherein the primary transmission point is one of the N transmission points;
- and
- receiving feedback information for the PDCP layer packets distributed to a secondary transmission point of the N transmission points, from the secondary transmission point or from the UE.
A primary transmission point in a multiple point transmission system, the primary transmission point comprising:
- a transmitter;
- a processor coupled to the transmitter, the processor in conjunction with the transmitter configured for distributing a plurality of packet data convergence protocol (PDCP) layer packets of a single bearer to N transmission points for transmission to a user equipment (UE), where N is an integer value greater than or equal to two, and wherein the primary transmission point is one of the N transmission points;
- and
- a receiver coupled to the processor and configured for receiving feedback information for the PDCP layer packets distributed to a secondary transmission point of the N transmission points, from the secondary transmission point or from the UE.
A method for operating a secondary transmission point in a multiple point transmission system, the method comprising:
- receiving, by the secondary transmission point from a primary transmission point in the multiple point transmission system, a plurality of packet data convergence protocol (PDCP) layer packets of a single bearer for transmission to a user equipment;
- and
- providing, by the secondary transmission point to the primary transmission point, feedback information for the plurality of PDCP layer packets received by the secondary transmission point from the primary transmission point.
A secondary transmission point in a multiple point transmission system, the secondary transmission point comprising:
- a receiver configured for receiving, from a primary transmission point in the multiple point transmission system, a plurality of packet data convergence protocol (PDCP) layer packets of a single bearer for transmission to a user equipment;
- a processor coupled to the receiver and configured for determining feedback information for the plurality of PDCP layer packets received by the secondary transmission point from the primary transmission point;
- and
- a transmitter coupled to the processor and configured for providing, to the primary transmission point, the feedback information for the plurality of PDCP layer packets received by the secondary transmission point from the primary transmission point.
