Transmission control method

摘要

This invention relates to signalling of control information related to retransmissions in a wireless communication network. According to one aspect of the invention, a method for controlling transmission over a wireless communication link is provided. The method comprises the step of indicating on a transmission resource control channel whether a HARQ retransmission process in a mobile station should be activated or deactivated.

主权项

1. A method, comprising:
determining, in a network node, whether at least a HARQ (Hybrid-Automatic-Repeat-Request) process of a multiplicity of HARQ processes should be activated or deactivated in a mobile station, wherein each HARQ process is responsible for generating positive or negative acknowledgements indicating delivery status of transmissions over a data channel so that, when the HARQ process is deactivated, the HARQ process does not send or process said acknowledgments, and transmitting an indication associated with said determining from the network node to the mobile station on a transmission resource control channel, wherein the transmission resource control channel is an enhanced absolute grant channel, wherein said indication is distinct from said positive or negative acknowledgements, and includes: a group of bits that has a specific value indicating that a specific HARQ process is to be activated or deactivated, and a specific value indicating that all HARQ processes are to be activated.
