Communication terminal and a method for reporting a channel quality
View Patent ↗A communication terminal comprising a determiner configured to determine whether a communication service used by the communication terminal via a communication channel is of a predetermined class and to determine a channel quality of the communication channel to be indicated to a communication network based on whether the communication service is of the predetermined class and a transmitter configured to indicate the channel quality to the communication network.
1. A communication terminal comprising:
a determiner configured to adapt a channel quality indicator when a communication network serving cell is not fully loaded and when a communication service used by the communication terminal via a communication channel is of a predetermined class; and
a transmitter configured to indicate the adapted channel quality indicator to the communication network.
2. The communication terminal of claim 1 , wherein the transmitter is configured to indicate the channel quality to the communication network by transmitting a channel quality indicator corresponding to the channel quality.
3. The communication terminal of claim 1 , wherein the transmitter is configured to indicate the channel quality to the communication network by transmitting acknowledgement messages at a rate corresponding to the channel quality.
4. The communication terminal of claim 1 , wherein the transmitter is configured to indicate the channel quality to the communication network by transmitting negative acknowledgement messages for data packets or omitting acknowledgement messages and negative acknowledgement messages for data packets at a rate corresponding to the channel quality.
5. The communication terminal of claim 1 , wherein the determiner is configured to determine the channel quality based on a candidate channel quality, wherein, if the communication service is of the predetermined class, the determiner reduces the candidate channel quality and determines the reduced candidate channel quality as the channel quality.
6. The communication terminal of claim 1 , wherein the communication service is of the predetermined class if the data communicated by the communication service is of a predetermined data type.
7. The communication terminal of claim 6 , wherein the predetermined data type includes speech data.
8. The communication terminal of claim 1 , wherein the communication service is of the predetermined class if the data communicated by the communication service is real-time data.
9. The communication terminal of claim 1 , wherein the predetermined class is a network layer or higher layer service class.
10. The communication terminal of claim 1 , wherein the predetermined class is a transport layer or higher layer service class.
11. The communication terminal of claim 1 , wherein the predetermined class is a class of real-time data transmission services.
12. The communication terminal of claim 1 , wherein the predetermined class is a class of speech or voice data transmission services.
13. The communication terminal of claim 1 , wherein the predetermined class is a class of voice calls.
14. The communication terminal of claim 1 , wherein the predetermined class is a class of latency sensitive communication services.
15. The communication terminal of claim 1 , wherein the predetermined class is a class of error rate sensitive communication services.
16. The communication terminal of claim 1 , wherein the communication channel is provided by the communication network.
17. The communication terminal of claim 1 , wherein the determiner is further configured to determine a load of the communication network and to determine the channel quality of the communication channel to be indicated to the communication network based on the load of the communication network.
18. A method for reporting a channel quality comprising:
determining whether a communication service used by the communication terminal via a communication channel is of a predetermined class;
determining a channel quality of the communication channel to be indicated to a communication network based on whether the communication service is of the predetermined class; and
adapting a channel quality indicator when a communication network serving cell is not fully loaded and when a communication service used by the communication terminal via a communication channel is of a predetermined class;
indicating the adapted channel quality indicator to the communication network.
