The values stated above are maximum limits. According to

Release 99, the maximum output power in a multislot configuration may be lower. The nominal reduction of maximum output power varies with the number of uplink timeslots used and amounts to 3.0dB for 2Tx, 4.8dB for 3Tx and 6.0dB for 4Tx.上述值為最大值。按照Release 99，多槽配置的最大輸出電源可能更低。最大輸出電源的降低標(biāo)準(zhǔn)隨上傳時(shí)隙的使用量而變化，2Tx為3.0dB，3Tx為4.8dB，4Tx為6.0dB。
