Abstract: A fronthaul multiplexer according to one aspect of the present invention combines uplink packets in a compressed state that is received from two or more radio units so that the uplink packets are accumulated and combined immediately when received or the uplink packets are recompressed using a compressing method with high compression efficiency when stored in a memory in order to reduce a use amount of memory.
