Abstract:
1. A method for transmitting a block of data from a transmitter to a receiver in a wireless communication system supporting HARQ and TTI bundling, the method comprising: a) transmitting a TTI bundle from the transmitter to the receiver, the TTI bundle comprising a first number of redundancy versions indicative of the block of data as encoded using HARQ; and b) following a determination at the transmitter that transmission of the TTI bundle failed to result in successful decoding of the block of data at the receiver, transmitting a second TTI bundle from the transmitter to the receiver, the second TTI bundle comprising a second number of redundancy versions indicative of the block of data as encoded using HARQ, the second number different from the first number, wherein an initial size of the TTI bundle is configured based at least in part on latency requirements for transmission of the block of data, wherein determining the initial size of the TTI bundle comprises adjusting the initial size of the TTI bundle downward when the latency requirements are reduced.
