Abstract

A method for a device and a node for preventing data transmission configuration conflict between the device and the node is disclosed. The node transmits a control message which is received by the device. The device determines a first data transmission configuration from the received control message. The device then determines a second data transmission configuration from a candidate set of configurations wherein the candidate set of configurations is associated with the first data transmission configuration. The device then transmits data and wherein the node receives the data in accordance with the second data transmission configuration. A device and node implementing the method is also disclosed.
