Multicell Cooperative Processing (MCP) has been recognized as a promising technique for increasing spectral efficiency of future wireless systems. Unfortunately the provided benefits of downlink MCP come at the cost of increased radio feedback and backhaul overhead; in FDD systems users need to feed back their channel state information (CSI) to the network(More)
—Multi-cell Cooperative Processing (MCP) has been recognised as an efficient technique for increasing spectral efficiency of future cellular systems. However the provided benefits come at the cost of increased overhead and computational complexity; Mobile Stations (MSs) need to feed back to their assigned Base Station (BS) their local channel state(More)
— Recent work on channel modeling and prediction has shown the feasibility of predicting the mobile radio channel, quite accurately, several milliseconds ahead in time for realistic Doppler spreads. Motivated by these results we consider op-portunistic scheduling algorithms that exploit both current and future channel estimates. We demonstrate how this(More)
Coordinated base station (BS) transmission has attracted much interest for its potential to increase the capacity of wireless networks. Yet at the same time, the achievable sum-rate with single-cell processing (SCP) scales optimally with the number of users under Rayleigh fading conditions. One may therefore ask if the value of BS coordination is limited in(More)
—Base station (BS) coordination is a key technique to handle intercell interference (ICI) in cellular networks. Nevertheless , recent work on scheduling indicates that the value of coordination is less prominent when the number of users grows large. More specifically, the loss in sum rate due to ICI in unco-ordinated networks can be made arbitrarily small(More)
