Beam Scheduling for 5G UE Power Saving

The patent segments the downlink control information transmission by dividing subframes into different types (first type and second type) based on beam usage patterns. The base station transmits using multiple beams only in first type subframes, while using a single beam in second type subframes. This segmentation allows the UE to selectively monitor only first type subframes for multi-beam control information, reducing power consumption while maintaining coverage reliability.

The patent implements periodic action by establishing a regular pattern where the base station alternates between first type subframes (with multiple beam transmissions) and second type subframes (with single beam transmission). This periodic structure enables the UE to predict and prepare for monitoring activities, reducing unnecessary continuous monitoring and thereby lowering power consumption while ensuring control information is transmitted periodically with multiple beams to maintain coverage.

The patent applies local quality by differentiating the transmission characteristics in different subframe types. In first type subframes, the base station uses multiple beams with specific scheduling patterns appropriate for high data rate requirements. In second type subframes, a simpler single-beam transmission is used. This local differentiation reduces the overall scheduling and monitoring complexity at the UE while preserving the high data rate capability where needed.

The patent implements partial action by having the UE monitor only a subset of subframes (first type subframes) for downlink control information rather than all subframes. This partial monitoring approach reduces the complexity of scheduling and monitoring operations at the UE while still capturing the necessary control information transmitted during multi-beam periods, thereby simplifying the overall system operation.
