METHOD AND ARRANGEMENT IN A COMMUNICATION SYSTEM |
摘要 |
The present invention relates to the area of communication, and especially to a method and an arrangement for antenna calibration in a communication system comprising a baseband unit (BBU) and distributed radio remote units (RRUs). The present invention aims to limit antenna calibration duration in the antenna calibration chain. A cable delay based on the length of the cable connecting the BBU and the RRU is obtained. A delay compensation is calculated based upon the cable delay. Thereupon the antenna calibration chain utilized by the BBU and the RRU is adapted based upon the delay compensation. |
