Abstract: A method for synchronizing at least two nodes on a network including one network node acting as a master node, the master node setting a base time T0,master, and sending elapsed time since T0,master to at least one other node acting as a slave node, and the at least one other node acting as the slave node receiving the elapsed time, and estimating and setting a value of a base time T0,slave based, at least partly, on the received elapsed time. Related apparatus and methods are also described.

Abstract: A method includes transmitting downlink signals to at least first and second mobile communication terminals over respective first and second traffic channels. Reception quality measures are obtained from the first and second mobile communication terminals for at least one of the traffic channels. Based on the reception quality measures, an expected downlink performance is estimated for simultaneous transmission to the first and second mobile communication terminals on a candidate shared traffic channel.

Abstract: A method includes assigning a communication channel for simultaneous transmission to at least first and second mobile communication terminals using a Time-Division Multiplexing (TDM) communication protocol. Upon determining that data is to be transmitted over the communication channel to both the first and the second mobile communication terminals, the data is transmitted at a first power level that is defined for transmission to the first mobile communication terminal as part of the simultaneous transmission. Upon determining that the data is to be transmitted over the communication channel only to the first mobile communication terminal, the data is transmitted at a second power level that is defined for transmission only to the first mobile communication terminal and is lower than the first power level.
