Abstract: A first wireless device receives, from a base station, a configuration of first reference signals to be transmitted on a first time-frequency resource and a configuration of second reference signals to be transmitted on a second time-frequency resource. The first wireless device measures one of the first reference signals and the second reference signals. The first wireless device switches to measuring the other one of the second reference signals, wherein the first reference signals are measured to generate first measurements and the second reference signals are measured to generate second measurements. The first wireless device obtains a selection of a communication path, for communicating data between the base station and the first wireless device. The first wireless device obtains a first radio frequency (RF) signal from one or more RF signals carried through the communication path.

Abstract: A first wireless device reports to a base station at least one of (a) a capability of the first wireless device for path selection or path combining and (b) a supported frequency range on the second time-frequency resource. The first wireless device receives, from the base station, first control information indicating whether the first wireless device should receive data on the first time-frequency resource from the base station, on the second time-frequency resource from the second device, or both the first and second time-frequency resources, wherein the data are transmitted from the base station on the first time-frequency resource. The first wireless device receives the data based on the first control information.
