Abstract: A method performed by an intermediate unit of a distributed base station system of a wireless communication network. The distributed base station system has a first base unit and a second base unit connected to the intermediate unit. The intermediate unit is further connected to a first remote unit, which is further connected for distributing wireless signals to pieces of User Equipment (UEs). The intermediate unit receives, from the first base unit, first data and sends the first data over a point-to-point connection to the first remote unit for further distribution wirelessly over a radio channel to the UEs. In response to the reception of the first data, a first indication is sent to the second base unit that the radio channel is free. The second base unit can send second data that is then to be sent from the remote unit towards the UEs on the radio channel.

Abstract: A first Wireless Local Area Network (WLAN) node and a method therein for performing a transmission to a second WLAN node in a WLAN. The first WLAN node identifies a third WLAN node transmitting a first signal (S1) overheard by the first WLAN node, and determines to transmit, to the second WLAN node, a second signal (S2) based on the identity of the third WLAN node and on a received power of the first signal. When determined to transmit the second signal, the first WLAN node determines a Modulation and Coding Scheme (MCS) index value by means of a link adaptation process specific for the identified third WLAN node and transmits to the second WLAN node, the second signal using the determined MCS index.

Abstract: A first node and a method therein for controlling transmission of a first signal. The first node is operating in a Basic Service Set (BSS) comprised in a Wireless Local Area Network (WLAN). The first node detects a second signal transmitted from a second node operating in the WLAN. Further, the first node compares a signal strength of the second signal with a threshold value for the second node, which threshold value is determined based on the node type of the second node. Furthermore the first node transmits the first signal when the signal strength of the second signal is below the threshold value, and defers from transmitting the first signal when the signal strength of the second signal is above the threshold value. Thereby the transmission of the first signal is controlled.
