Method for data transmission and communication system
View Patent ↗A method for data transmission is provided for determining movement speed and/or location of a mobile communication device; selecting, based on the movement speed and/or the location of the mobile communication device a frequency hopping mode from a plurality of frequency hopping modes to be used for data transmission to or from the mobile communication device; and transmitting the data using the selected frequency hopping mode.
1. A method for data transmission, comprising:
receiving information about inter cell interference generated by the mobile communication device;
selecting, based on the received information about the inter cell interference, a frequency hopping mode from a plurality of frequency hopping modes to be used for data transmission to or from the mobile communication device;
wherein according to a first frequency hopping mode, frequency hops are more frequent than according to a second frequency hopping mode, and the first frequency hopping mode is selected if the inter cell interference lies above a first threshold; and
transmitting the data using the selected frequency hopping mode.
2. The method according to claim 1 , wherein the second frequency hopping mode is a semi-statical allocation of sub-carriers.
3. The method according to claim 1 , wherein if a movement speed of the mobile communication device lies under a second threshold or lies above a third threshold the second frequency hopping mode is selected.
4. The method according to claim 1 , wherein if the mobile communication device is located at the border of a radio cell, the first frequency hopping mode is selected.
5. A communication system, comprising:
a receiving circuit for receiving information about inter cell interference generated by the mobile communication device;
a selecting circuit configured to select, based on the received information about the inter cell interference, a frequency hopping mode from a plurality of frequency hopping modes to be used for data transmission to or from the mobile communication device;
wherein according to a first frequency hopping mode, frequency hops are more frequent than according to a second frequency hopping mode;
the selecting circuit being configured to select the first frequency hopping mode if the inter cell interference lies above a first threshold; and
a transmitting circuit configured to transmit data using the selected frequency hopping mode.
6. The communication system according to claim 5 , wherein the receiving circuit and the selecting circuit are located in a radio access network of the communication system.
7. The communication system according to claim 5 , wherein the transmitting circuit is located within the mobile communication device.
8. A communication system comprising:
a receiving means for receiving information about inter cell interference generated by the mobile communication device;
a selecting means for selecting, based on the received information about the inter cell interference, a frequency hopping mode from a plurality of frequency hopping modes to be used for data transmission to or from the mobile communication device;
wherein according to a first frequency hopping mode, frequency hops are more frequent than according to a second frequency hopping mode;
the selecting means being configured to select the first frequency hopping mode if the inter cell interference les above a first threshold; and
a transmitting means for transmitting data using the selected frequency hopping mode.
