Signaling of modulation configuration
The present disclosure pertains to a terminal for a wireless network, the terminal being adapted to receive a control message. The terminal further is adapted to read from one of a set of alternative tables based on the control message, and to perform modulation configuration based on information read from the table.
1. A terminal for a wireless network, the terminal being configured to:
receive a control message including at least one table indication parameter corresponding to a transmission mode of the terminal, the transmission mode of the terminal determining a number of the at least one table indication parameter used by the terminal;
read from one of a set of alternative tables based on the at least one table indication parameter of the control message; and
perform modulation configuration based on information read from the table.
2. The terminal according to claim 1 , wherein the set of alternative tables refers to different modulation schemes.
3. The terminal according to claim 2 , wherein the at least one table indication parameter configures a MCS table for both of two measurement subframe sets and at the same time configures a CQI table for one of the measurement subframe sets.
4. The terminal according to claim 3 , the terminal being configured to operate with a 256QAM MCS table, if one of a first and second measurement subframe sets is configured with a 256QAM CQI table.
5. The terminal according to claim 1 , wherein the at least one table indication parameter configures a MCS table for both of two measurement subframe sets and at the same time configures a CQI table for one of the measurement subframe sets.
6. The terminal according to claim 1 , the terminal being configured to operate with a 256QAM MCS table, if one of a first and second measurement subframe sets is configured with a 256QAM CQI table.
7. A method for a terminal for a wireless network, the method comprising:
receiving a control message including at least one table indication parameter corresponding to a transmission mode of the terminal, the transmission mode of the terminal determining a number of the at least one table indication parameter used by the terminal;
reading from one of a set of alternative tables based on the at least one table indication parameter of the control message; and
performing modulation configuration based on information read from the table.
8. The method according to claim 7 , wherein the set of alternative tables refers to different modulation schemes.
9. The method according to claim 8 , wherein the at least one table indication parameter configures a MCS table for both of two measurement subframe sets and at the same time configures a CQI table for one of the measurement subframe sets.
10. The method according to claim 9 , further comprising operating with a 256QAM MCS table, if one of a first and second measurement subframe sets is configured with a 256QAM CQI table.
11. The method according to claim 7 , wherein the at least one table indication parameter configures a MCS table for both of two measurement subframe sets and at the same time configures a CQI table for one of the measurement subframe sets.
12. The method according to claim 7 , further comprising operating with a 256QAM MCS table, if one of a first and second measurement subframe sets is configured with a 256QAM CQI table.
13. A base station for a wireless network, the base station being configured to:
determine a control message;
transmit the control message to a terminal; and
the control message comprising at least one table indication parameter corresponding to a transmission mode of the terminal and indicating a table of a set of alternative tables to be used, the transmission mode of the terminal determining a number of the at least one table indication parameter to be used by the terminal.
14. The base station according to claim 13 , wherein the set of alternative tables refers to different modulation schemes.
15. The base station according to claim 13 , wherein the at least one table indication parameter configures a MCS table for both of two measurement subframe sets and at the same time configures a CQI table for one of the measurement subframe sets.
16. The base station according to claim 13 , the control message being adapted for configuring the terminal for operating with a 256QAM MCS table, if one of a first and second measurement subframe sets is configured with a 256QAM CQI table.
