    • An LED light shaping device and illumination system are provided. According to one embodiment, a light shaping lens is configured to shape light emitted from a light source and direct the light on a display panel for projection. The light shaping lens comprises a light input surface configured to receive light emitted from the light source a reflective surface configured to reflect at least part of the light received by the light source; and a light output surface having a first curvature in a first direction and a second curvature in a second direction, wherein the light output surface is configured to emit the light that is received by the light input surface and reflected by the reflective surface, and wherein the first curvature and the second curvature are configured to shape the light such that the emitted light has an oval cross section.

    • The present invention discloses a method and a base station for adjusting a persistent allocation of resource, wherein the method comprises: a base station sends a resource persistent allocation message to a terminal via a downlink channel, wherein the base station indicates a resource de-allocation by a resource allocation flag in the resource persistent allocation message, and indicates whether a resource hole filling is needed by the resource shifting indicator in the resource persistent allocation message, wherein under the circumstance that the resource hole filling is needed, the location of a de-allocated resource is carried in the resource persistent allocation message; and under the circumstance that no resource hole filling is needed, the identifier of the terminal is carried in the resource persistent allocation message. By using the present invention, the information such as the terminal identifier can be carried optionally by modifying the content carried in the resource persistent allocation message, so that the redundant content in the message is eliminated, the problem that the efficiency of system frequency spectrum is reduced due to the redundant content in the message is avoided, system resources are saved, and system performances are improved.
    • 本发明公开了一种用于调整资源的持续分配的方法和基站,其中所述方法包括:基站经由下行链路信道向终端发送资源持续分配消息,其中,所述基站指示资源去分配 通过资源持续分配消息中的资源分配标志,并且指示资源持续分配消息中的资源移动指示符是否需要资源空穴填充,其中在需要资源充填的情况下, 资源持久分配消息中承载了分配资源; 在不需要资源填充的情况下,终端的标识符在资源持久性分配消息中被携带。 通过使用本发明,可以通过修改资源持久性分配消息中携带的内容来选择性地携带诸如终端标识符的信息,从而消除消息中的冗余内容,系统频谱的效率为 避免了消息中冗余内容的减少,节省了系统资源,提高了系统性能。
