The recently emerging high speed downlink packet access (HSDPA) enhances conventional WCDMA systems according to the UMTS standard with data rates of up to 14 MBit/s in the downlink direction. This is achieved by using adaptive modulation and coding as well as a fast hybrid automatic repeat request (HARQ) mechanism. This functionality is implemented close to the air interface in the Node B. In addition to the data buffer in the RNC, this requires a second data buffer in the Node B. Consequently… CONTINUE READING
