摘要:
A plasma display panel (PDP) protective layer including a ternary compound in the form of BaXO, wherein X is selected from the group consisting of Sc, Y, Gd, La, Er, Ho, Nd, Sm, and Ce. Such protective layer has excellent electron emission characteristics and phase stability.
摘要:
Disclosed is a material for forming a protective layer, a protective layer employing the material and a PDP with the protective layer. Unlike conventional protective layers which employ MgO created in conditions of pressurized artificial gas, the instant protective layer uses MgO created by heating Mg and allowing it to oxidize naturally in air. The result is MgO with fewer defects that is more effective as a protective layer in many uses, such as in a PDP. The instant MgO also shows many specific spectral characteristics and contains impurities in amounts of less than about 2 ppm each. Also disclosed is a PDP which takes advantage of the advantages of the inventive protective layer.

摘要:
In a mobile communication system, an Advanced Mobile Station (AMS) sends, to an Advanced Base Station (ABS), a message including information indicating whether the AMS supports a sounding antenna switching scheme. If the information indicates that the AMS supports the sounding antenna switching scheme, the message including the information includes information indicating an antenna configuration that the AMS desires to use in a sounding antenna switching operation.

摘要:
A method for performing a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless mobile communication system that uses Frequency Division Duplex (FDD) or Time Division Duplex (TDD) frames each having a plurality of subframes for communication are provided, in which an HARQ timing including a transmission time of a data burst and a transmission time of an HARQ feedback, for DL HARQ is determined according to data burst assignment information transmitted in a #l DownLink (DL) subframe of a #i frame, and an HARQ operation is performed according to the determined HARQ timing. At least one frame index and at least one subframe index that represent the HARQ timing are determined by using l and i.
摘要:
An apparatus and method for controlling a Hybrid Automatic Repeat reQuest (HARQ) operation in a transmitter of a wireless mobile communication system using each frame constituted by a plurality of subframes are provided. In the method for controlling an HARQ operation, indication information indicating a subframe position where transmission of a data burst starts and the number of subframes required for transmission of the data burst is transmitted to a receiver through an i-th frame. When the number of subframes does not exceed a threshold, it is determined that the data burst at the subframe position indicated by indication information of an (i+1)-th frame is retransmitted to the receiver. When the number of subframes exceeds the threshold, it is determined that the data burst at the subframe position indicated by indication information of an (i+n)-th frame, where n is a positive integer exceeding 1, is retransmitted to the receiver.
