Some PUSCH signal meets preset condition out, can also stop the PUSCH letter for calculating remaining the compensated processing signal patch Nei
Number corresponding redundant code, or stop compensating the PUSCH signal in the signal patch.
Mode three:
The signal power of the repeating signal unit by compensation deals is calculated simultaneously and calculates the repetition Jing Guo compensation deals
The redundant code of signal element that is to say in conjunction with aforesaid way one and mode two, respectively to the weight of compensated processing in the signal patch
Complex signal unit carries out the calculating of signal power and redundant code, then is advised respectively according to the judgement of aforesaid way one and aforesaid way two
Then judge with the presence or absence of the repeating signal unit for meeting preset condition in the signal patch, only is judging to repeat to believe in the signal patch
The signal power of number unit meets predetermined power threshold value, and when its corresponding redundant code is matched with default redundant code, just determining should
There is the repeating signal unit for meeting preset condition in signal patch.
Finally it should be noted that link signal retransmission processing method provided in this embodiment is applicable not only to uplink
Transmission, is also applied for downlink transmission.
The link signal retransmission processing method provided through this embodiment, recipient is former according to preset signals unit fragment
When then judging that current repeating signal unit constitutes a signal patch, each repeating signal unit in the signal patch will be carried out
