## 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.

## Claims

### Claim 1

A method for multiple point transmission operation, the method comprising:
modifying a configuration of a radio bearer for use in a multiple point transmission to a user equipment according to operating condition information of the user equipment;
reconfiguring the radio bearer according to the modified configuration; and
initiating a multiple point transmission to the user equipment using the reconfigured radio bearer.
