摘要
Various aspects of the present disclosure generally relate to wireless communication. A transmitter node and a relay node transmit, to a base station, feedback related to complex channel estimates associated with beam pairs providing viable paths for a first link between the transmitter node and the base station, a second link between the relay node and the base station, and a third link between the transmitter node and the relay node. The transmitter node transmits a signal to the base station using a transmit beam associated with a first beam pair and to the relay node using a transmit beam associated with a second beam pair. The base station receives the signal from the transmitter node and an estimate of the signal from the relay node via a receive beam configured based at least in part on the complex channel estimates included in the feedback. Numerous other aspects are provided.
