Claim
1. A method for predicting the performance of radio link in a wireless communication terminal, the method comprising: hypothesizing a first codeword; hypothesizing a second codeword including information associated with the first codeword; obtaining channel state information from a received signal; estimating a decoder error rate of the first codeword under a condition that the second codeword may not be decoded correctly, the decoder error rate is estimated using the channel state information.
2. The method of Claim 1, wherein the received signal corresponds to a cell-specific reference signal.
3. The method of Claim 1 further comprising determining a synchronization status of the radio link based upon the estimated decoder error rate of the first codeword.
4. The method of Claim 1, the first codeword corresponds to a control channel and the second codeword corresponds to a control format indicator channel carrying information related to transmission parameters of the control channel.
5. The method of Claim 1, the first codeword corresponds to a data payload and the second codeword corresponds to a control channel necessary for determining transmission parameters and scheduling information of a data payload.
6. The method of Claim 1 further comprising generating channel quality indication reports based on the estimated decoder error rate for the first codeword.
7. The method of Claim 1, the information in the second code word is a transmission parameter corresponding to any one of: a number of symbols on which the first codeword is mapped, time-frequency resources on which the first codeword is mapped, or an encoding method used for generating the first codeword, or an information size of a payload of the first codeword, or a block length of the first codeword, or a rate of the first codeword, or a redundancy version number of the first codeword, or a transmit antenna configuration used for the first codeword or pre-coding used for the first codeword.
8. The method of Claim 1 further comprising hypothesizing a third codeword including information associated with the second codeword; estimating the decoder error rate of the first codeword under a condition that the second and third codewords may not be decoded correctly, the decoder error rate is estimated using a mapping function that includes channel state information.
9. The method of Claim 8, wherein the first codeword corresponds to a data payload and the second codeword corresponds to a control channel, wherein the information of the second codeword includes transmission parameters and scheduling information of the data payload; and the third codeword corresponds to a control format indicator channel wherein the information of the third codeword includes information related to a transmission parameters of the control channel
10. The method of Claim 8 further comprising generating channel quality indication reports based on the estimated decoder error rate for the first codeword
11. The method of Claim 8, wherein the information in the third code word is a transmission parameter corresponding to any one of: a number of symbols on which the second codeword is mapped, time-frequency resources on which the second codeword is mapped, or an encoding method used for generating the second codeword, or an information size of a payload of the second codeword, or a block length of the second codeword, or a rate of the second codeword, or a redundancy version number of the first codeword, or a transmit antenna configuration used for the second codeword or pre-coding used for the second codeword
12. A wireless communication terminal comprising: a transceiver; a controller coupled to the transceiver, the controller configured to hypothesize a first codeword and to hypothesize a second codeword including information associated with the first codeword, the controller configured to obtain channel state information from a received signal, the controller configured to estimate a decoder error rate of the first codeword under a condition that the second codeword is not decoded correctly, the decoder error rate is estimated using a mapping function that includes channel state information
13. The terminal of Claim 12, the controller configured to determine synchronization status of the radio link based upon the estimated decoder error rate of the first codeword
14. The terminal of Claim 12, wherein the first codeword corresponds to a control channel and the second codeword corresponds to a control format indicator channel carrying information related to transmission parameters of the control channel
15. The terminal of Claim 12, wherein the first codeword corresponds to a data payload and the second codeword corresponds to a control channel necessary for determining transmission parameters and scheduling information of a data payload
16. The method of Claim 12, the controller configured to generate channel quality indication reports based on the estimated decoder error rate for the first codeword
17. The terminal of Claim 12, wherein the information in the second code word is a transmission parameter corresponding to any one of: a number of symbols on which the first codeword is mapped, time-frequency resources on which the first codeword is mapped, or an encoding method used for generating the first codeword, or an information size of a payload of the first codeword, or a block length of the first codeword, or a rate of the first codeword, or a redundancy version number of the first codeword, or a transmit antenna configuration used for the first codeword or pre-coding used for the first codeword
18. The terminal of Claim 12, the controller configured to hypothesize a third codeword including information associated with the second codeword and to estimate the decoder error rate of the first codeword under a condition that the second and third codewords are not decoded correctly
19. The terminal of Claim 18, wherein the first codeword corresponds to a data payload and the second codeword corresponds to a control channel, wherein the information of the second codeword includes transmission parameters and scheduling information of the data payload, and the third codeword corresponds to a control format indicator channel wherein the information of the third codeword includes information related to a transmission parameters of the control channel.
20. The terminal of Claim 18, the controller configured to generate channel quality indication reports based on the estimated decoder error rate for the first codeword.
21. The terminal of Claim 18, the information in the third code word is a transmission parameter corresponding to any one of: a number of symbols on which the second codeword is mapped, time-frequency resources on which the second codeword is mapped, or an encoding method used for generating the second codeword, or an information size of a payload of the second codeword, or a block length of the second codeword, or a rate of the second codeword, or a redundancy version number of the first codeword, or a transmit antenna configuration used for the second codeword or pre-coding used for the second codeword.']
