  • Patent number: 11076417
    Abstract: This disclosure generally relates to downlink transmission scheduling for D2D UE based on subframe pattern. In one embodiment, the D2D UE may provide the BS with information on a pattern of the D2D reception subframes that indicates the usage of at least some of the D2D reception subframes. From the pattern, the BS may determine one or more D2D reception subframes in which the UE wants to monitor the D2D reception and/or the cellular reception. Then the BS may avoid scheduling the downlink transmission in the subframes in which the UE monitors the D2D reception. In the other D2D reception subframes, the downlink transmission can be scheduled. In this way, the UE can properly switch between the D2D reception and cellular reception, without any conflicts or downlink resource waste.
