Abstract: The present disclosure discloses a system including a controller and a plurality of radio heads communicatively coupled to the controller. The controller transmits a synchronization signal to each of the radio heads to synchronize the local clocks in the radio heads to a master clock in the controller. The controller also transmits packets to the radio heads. Each of the radio heads includes a deframer. For a radio head, upon detecting that a received packet from the controller includes an error, the deframer alters the received packet to maintain the synchronization between the controller and the radio head and transmits data contained within the altered packet.

Abstract: The invention relates to a method for transmitting data via a communications channel (106), in which the data is transmitted with a transmission frame, wherein the transmission frame has at least one prioritisation field (PCP) for establishing the priority of the message and a data field, wherein the prioritisation field (PCP) functions to control the bus access by prioritising the messages. For this purpose, a bus access controller is used, in which the priority of at least the last received data packet is stored in a minimum priority storage cell (330). After receiving a data packet, a timer (320) is started, for which a timeout value is set, which is reset when a following packet is received. After reaching the timeout value, a decrementing of the value stored in the minimum priority storage cell (330) occurs.
