    Abstract: A method for operating a DAS includes providing a set of digital remote units (remotes) operable to send and receive wireless radio signals. Each of the set of remotes is associated with a geographic area. The method also includes providing a digital access unit (host) operable to communicate with the set of remotes, receiving uplink signals at one or more of the set of remotes, and monitoring train activity in the geographic areas. The method further includes increasing a gain coefficient associated with one of the set of remotes in response to determining an increase in monitored train activity, decreasing a gain coefficient associated with another of the set of remotes in response to determining a decrease in monitored train activity, and transmitting, to the host, scaled uplink signals associated with the one of the set of remotes and the another of the set of remotes.

    Abstract: A method for controlling transmit power of a preamble sequence by a Subscriber Station in an Orthogonal Frequency Division Multiple Access communication system, the system dividing an entire frequency band into a plurality of sub-carrier bands, transmitting an preamble sequence for an Adaptive Antenna System, transmitting a data symbol through remaining sub-carrier bands excluding the sub-carrier bands. The method includes determining the transmit power used for transmitting the data symbol; and determining the transmit power used for transmitting the preamble sequence to be identical to a preset threshold transmit power when the transmit power of the data symbol is smaller than the threshold transmit power, and determining the transmit power used for transmitting the preamble sequence to be identical to the transmit power of the data symbol when the transmit power of the data symbol exceeds the threshold transmit power.

    Abstract: Embodiments herein relate to a method performed by a radio unit (101) for controlling power levels of spatially separated transceivers (110-119) connected to the radio unit (101) via corresponding antenna ports (a-j). Each transceiver (110-119) is capable of performing measurements on uplink transmissions from wireless devices in a wireless communication network (100). The radio unit (101) receives, from each transceiver (110-119), measurements on uplink transmissions from wireless devices. Then, the radio unit (101) determines, for each transceiver (110-119), a load based on how many wireless devices that have the transceiver as the transceiver with the most relevant measurement for its uplink transmissions. The radio unit (101) also controls a power level of at least one first transceiver (110) based on at least one of the determined loads for the transceivers (110-119). Embodiments of the radio unit (101) are also described.
