A grant may allocate resources for an uplink transmission by a user equipment (UE) in a system using beamforming, where the resources may be used by the UE to transmit data or control information during a time that a base station is listening in a certain receive beam direction. A UE may be in communication with a base station using beamformed transmissions, and the base station may send a resource grant to the UE for uplink transmissions that correspond to a receive beam direction of a beamsweeping operation. The UE may then transmit data and/or uplink control information to the base station according to the resource grant and when the base station is listening in the corresponding direction. In some examples, the UE may send the uplink transmission to the serving base station, and transmit a random access channel to another base station based on the beamsweeping operation.
