Communication method and arrangement in a code division multiple access (CDMA) radio system

A communication arrangement, the arrangement comprising:

• at least two transceivers of the radio system configured to communicate with a packet switched connection through a radio interface;
• a measuring mechanism configured to measure a quality of the packet switched connection;
• an adjusting mechanism configured to adjust a target Signal Interference Ratio based on the quality measured;
• a transceiver configured to receive packets and to transmit a request to retransmit when there is a failure to receive at least one packet;
• a transceiver configured to transmit packets and configured to retransmit at least one retransmission packet requested as a response to the request;
• and
• a controller configured to set a lower target Signal Interference Ratio for retransmission of a packet than the target Signal Interference Ratio for a first transmission of the corresponding packet.

A communication arrangement, the arrangement comprising:

• communicating means for communicating between at least two transceivers of a radio system using a packet switched connection through a radio interface;
• measuring means for measuring a quality of the packet switched connection;
• adjusting means for adjusting a target Signal Interference Ratio based on the quality measured;
• transmitting means for transmitting, from a transceiver receiving packets, a request to retransmit at least one packet having a failed reception;
• retransmitting means for retransmitting, from a transceiver transmitting packets, at least one retransmission packet requested as a response to the request;
• and
• controlling means for controlling a transmission power by setting a lower target Signal Interference Ratio for retransmission of a retransmission packet than the target Signal Interference Ratio for a first transmission of a corresponding packet.
