摘要： Disclosed is a method for transmitting wireless base band data, comprising: receiving a downlink base band signal transmitted by a base band processing unit (BBU), processing the downlink base band signal to module the downlink base band signal into a downlink intermediate frequency analog signal, and outputting the downlink intermediate frequency analog signal to an Ethernet cable; obtaining, from the Ethernet cable, an uplink intermediate frequency analog signal which is detected and fed back, and processing the uplink intermediate frequency analog signal; and taking the processed uplink intermediate frequency analog signal as a feedback input of digital pre-distortion (DPD), obtaining an intermediate frequency analog signal from the Ethernet cable, converting the intermediate frequency analog signal into an uplink base band signal, and sending the uplink base band signal to the BBU. Embodiments of the present invention also provide a corresponding apparatus and radio remote unit (RRU) for transmitting wireless base band data. By adopting the solutions disclosed in the embodiments of the present invention, transmission of a wireless base band signal between a BBU and an RRU can be implemented through an Ethernet signal+an intermediate frequency signal+power over Ethernet (EIP) device, thereby avoiding a high network deployment cost caused by the need of laying down an optical fiber or a microwave transmission network again.

摘要： An imbalanced area pilot frequency transmission power enhancement method and a base station are provided. In accordance with the transmission power and increment of a main public pilot frequency channel prior to power enhancement, post-power enhancement main public pilot frequency channel transmission power is obtained. The transmission power of a downlink traffic channel is the same as transmission power prior to power enhancement. In accordance with the transmission power of the main public pilot frequency channel prior to power enhancement, the downlink traffic channel transmission power is also obtained. The post-power enhancement main public pilot frequency channel transmission power and the downlink traffic channel transmission power are used to transmit data in the main public pilot frequency channel and the downlink traffic channel, respectively.
