Abstract
The present invention relates to method, terminal device and network device for providing redundancy parameters for an automatic repeat request processing at a terminal device. At least one sequence of redundancy parameters is selected from a predetermined set of sequences and is signaled to the terminal device by using a strategy information indicating the selected parameter sequence. Thereby, the network operator is able to select the redundancy version strategy to be used by the terminal device, while little signaling is required between the network and the UE. Moreover, a flexible strategy can be provided where individual redundancy version strategies can be allocated to the connections.
Claims31
A method, comprising:
- providing a set of predetermined sequences of redundancy parameters to a terminal device, said redundancy parameters each indicating a redundancy version for an automatic repeat request processing at the terminal device;
- selecting at least one of said set of predetermined sequences;
- and
- transmitting information indicating the selected at least one sequence to the terminal device to provide said redundancy parameters for the automatic repeat request processing at said terminal device,
- wherein said information comprises at least one of an index and a pointer to said selected at least one sequence.
