Abstract: Methods and apparatuses are provided for power headroom report regarding multiple TRPs in a wireless communication system. The systems and methods of the present invention address, expand, and improve how networks perform power control on multiple TRPs, how networks manage power control for uplink transmissions for different links, and how a UE derives one or more PH/PHR for different links.

Abstract: A projection apparatus includes a casing, a projection lens, a first fan, a first light source module, a second light source module, a first heat dissipation module, and a second heat dissipation module. A disposing direction of the projection lens divides an accommodating space of the casing into a first region and a second region. The first fan, the first light source module, the second light source module, the first heat dissipation module, and the second heat dissipation module are located in the first region. The first heat dissipation module includes a first heat dissipation fin set and a first heat pipe. The first heat pipe is connected to the first base of the first light source module and the first heat dissipation fin set. The first heat dissipation fin set is disposed adjacent to a first air inlet, and in an axial direction of the first fan.

Abstract: The disclosure provides a projection device including a casing structure, a light source, a light valve element and a projection lens. The casing structure includes a main casing and at least one shielding structure. The main casing has an inner space and at least one heat dissipation opening, and the at least one shielding structure is connected to an inner surface of the main casing to be located in the inner space. The light source is disposed in an arrangement region of the inner space for providing an illumination beam. The light valve element is disposed in the arrangement region for converting the illumination beam into an image beam. The projection lens is disposed in the arrangement region for projecting the image beam. The shielding structure shades the at least one heat dissipation opening, such that the arrangement region is invisible from outside of the main casing.

Abstract: A light source module comprises a first light source, a second light source, a first heat sink structure, and a second heat sink structure. The second light source disposed downstream of a main airflow flowing through the first light source module. The first heat sink structure has a plurality of first heat sink fins. The second heat sink structure has a plurality of second heat sink fins, wherein the first light source and the second light source are disposed along a first direction. The first heat sink structure and the second heat sink structure are disposed along the first direction, the first heat sink fins are arranged along the first direction, the second heat sink fins are arranged along a second direction, and the first direction is different from the second direction. A projection apparatus comprising the light source module is also provided.
