Abstract:
A system and method for system and method for multiplexing control and data channels in a multiple input, multiple output (MIMO) communications system are provided. A method for transmitting control symbols and data symbols on multiple MIMO layers includes selecting a first set of codewords from Ncw codewords, distributing control symbols onto the first set of layers, placing data symbols of the first set of codewords onto the first set of layers, placing data symbols of the (Ncw-Ncw1) remaining codewords to remaining layers if Ncw>Ncw1, and transmitting the multiple MIMO layers. The first set of codewords is associated with a first set of layers from the multiple MIMO layers, and the Ncw codewords are to be transmitted simultaneously and the first set of codewords comprises Ncw1 MIMO codewords, where Ncw and Ncw1 are integers greater than or equal to 1. The remaining layers are MIMO layers from the multiple MIMO layers not in the first set of layers.
Abstract:
An elevator car includes supporting sections, which are arranged on a car frame. Each supporting section has a foot, a first arm and a second arm. The foot is fastened to the car frame, at their free ends the arms converge and form a slit-shaped constriction, into which panel sections of panels that form walls or a ceiling can be clipped. The arms possess spring properties and, at the constriction, can be moved apart against a spring force. The arms hold the panel sections in position in the area of the constriction.
Abstract:
In one embodiment, a method for transmitting information includes processing a downlink transport channel to generate a transport block (TB) having a TB size. The TB size is selected by selecting a modulation and coding scheme index (ITBS) and a physical resource block index (NPRB). The TB size for the selected ITBS and NPRB is selected so that an effective code rate at an user equipment (UE) does not exceed a specified threshold. The effective code rate is defined as a number of downlink (DL) information bits including TB cyclic redundancy check (CRC) bits and code block CRC bits divided by a number of physical channel bits on Physical Downlink Shared Channel (PDSCH). The transport block is mapped to multiple spatial layers. The number of spatial layers N is greater than or equal to three. The multiple spatial layers are transmitted to the UE.
Abstract:
An exemplary cable holding device includes a supporting member and sliding bars. The supporting member includes a first sidewall, a second sidewall spaced from the first sidewall, and a bottom connecting the first sidewall to the second sidewall. Each of the first sidewall and the second sidewall defines through holes. Each bar slidably extends through a corresponding one of the through holes. The cables pass over ends of the sliding bars between the first sidewall and the second sidewall.

A display device having an illumination device is provided. The display device includes a display, a body, and an illumination device. The display and the illumination device are mounted on the front surface of the body. A receiving space is defined in the front surface of the body and below the display. The illumination device is received in the receiving space and is pivotally connected to the body.
Abstract:
An electronic device includes a main body and a cover. The main body includes a front surface with a display disposed thereon, a rear surface, a bottom surface, a top surface, and two opposite lateral surfaces. Each lateral surface defines a sliding slot extending substantially from the center of the lateral surface towards the bottom surface. The cover includes a cover portion and two connecting portions. The two connecting portions are located at two ends of the cover portion spatially corresponding to the sliding slots. The connecting portion includes a supporting portion and a latching portion. The supporting portion protrudes substantially perpendicularly from the cover portion. The latching portion extends into the sliding slot from the free end of the supporting portion and slidably latches with the sliding slot.
Abstract:
A blood smear preparation device includes a base; a carrying table for carrying a microscope slide thereon and being supported on the base; a lifting mechanism mounted to the base; a retaining stand suspended from an output end of the lifting mechanism; a spreader holder rotatably suspended from the retaining stand about a second rotating shaft and positioned above the carrying table; a positioning member for positioning the spreader; and a torsion elastic member provided about the second rotating shaft, with a free end of the torsion elastic member abutting against the spreader holder. With the provision of the second rotating shaft and the torsion elastic member, the spreader has a certain degree of flexibility and self-adaptiveness. Even if the spreader or the microscope slide has no good micro-flatness or straightness, the device may automatically adjust the positions of the spreader and the microscope slide to achieve a line contact and a surface contact, and thus ensure the quality of the blood smear.
