1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
select a first candidate beam for communication with a first transmitter user equipment;
select a second candidate beam for communication with a second transmitter user equipment;
determine a first radio resource expected to be used by the first transmitter user equipment for a first radio transmission to a receiver user equipment;
determine a second radio resource expected to be used by the second transmitter user equipment for a second radio transmission to the receiver user equipment;
determine that the first radio resource overlaps in time, at least partially, with the second radio resource, and determine that the first candidate beam does not match the second candidate beam;
determine whether to:
receive the first radio transmission using the first candidate beam,
receive the second radio transmission using the second candidate beam, or
receive the first radio transmission and the second radio transmission using a third candidate beam; and
select a beam for reception of the first radio transmission and the second radio transmission based at least partially on at least one of:
a first priority of the first radio transmission and a second priority of the second radio transmission;
an angular distance between a first expected angle-of-arrival of the first radio transmission and a second expected angle-of-arrival of the second radio transmission; or
a first expected interference in the first radio resource expected to be used by the first transmitter user equipment or a second expected interference in the second radio resource expected to be used by the second transmitter user equipment.
