摘要： The present disclosure relates to a MIMO system comprising remote radio unit, RRU and central unit. The RRU comprises: a binary phase shift keying, BPSK, modulator, configured to modulate a BPSK waveform by a local oscillator, LO, signal to generate a stimulus signal, wherein the LO signal is derived from a downlink optical signal received via downlink radio over fiber, DL-ROF, from a central unit, CU; and an optical signal generator, in particular a laser, configured to generate an uplink optical signal based on the stimulus signal for transmission via uplink radio over fiber, UL-ROF, to the CU.

摘要： A data transmission method, radio access network equipment, wireless gateway and system are disclosed by the present invention. A downlink data transmission method in the radio access network includes: compressing the downlink data packet when receiving the downlink data packet transmitted by a radio core network equipment; transmitting the compressed downlink data packet to a radio frequency module and transmitting it in a wireless mode via the air interface. An uplink data transmission method in the wireless gateway includes: compressing the uplink data packet when receiving the uplink data packet transmitted by a user terminal; transmitting the compressed uplink data packet to the radio frequency module and transmitting it in a wireless mode via the air interface. The data transmission method, radio access network equipment, wireless gateway and system provided by the present invention can compress the data packet transmitted through the air interface by setting compression function in the radio access network equipment or the wireless gateway, thus reducing the bandwidth occupied by the data packet, and improving the resource transmission capacity of the air interface accordingly.

摘要： A method for data transmission between baseband process unit and radio frequency process unit, includes: predefining the format of packet used to store the same type of data, and packaging the same type of data into the same packet when data is received, then determining the interface transmission rate of the transmission component according to the rule that the bandwidth of transmission component is larger than the total bandwidth of packets. While an adapter used for transmission channel between baseband process unit and radio frequency process unit includes a packet defining transmission module, a packet total bandwidth determining module and an interface transmission rate determining module. The present invention implements the data transmission between baseband process unit and radio frequency process unit using a single transmission component in different service data rate, and the flexibility of the transmission data format is increased, the selection range of transmission component is increased, and the flexibility of data transmission is further enhanced.
