OPPORTUNISTIC ACTIVATION OF RELAYS IN CLOUD RADIO ACCESS NETWORKS

摘要

According to exemplary embodiments, a method for wireless communications includes identifying at least one UE that can be served by a plurality of transmission points (TP) on a first frequency or by a relay on a second frequency Evaluating a first performance metric that is conditioned on a UE served by a relaying unit and a second performance metric that is conditioned on a UE served by a plurality of TPs, Determining whether the UE should be served by a plurality of TPs on a first frequency or by a relay on a second frequency, and determining whether the UE should be served by a repeater or a plurality of TPs based on the determination Or taking action to switch the UE from being served by them.
