摘要:
An apparatus and method for estimating UpLink (UL) transmission timing in a Mobile Station (MS) of a wireless communication system are provided. The method includes tracking DL timing by using a DL preamble signal received for each frame; estimating a time offset between a previous frame and a current frame by using the DL timing tracked for each frame; and estimating the UL transmission timing by using the estimated time offset.

A system is provided for transmitting/receiving downlink resource allocation information in a communication system. In the system, a base station generates first information including downlink resource allocation information necessary for supporting a first mode supported by the base station, generates second information including length information of the first information, and transmits the first information and the second information. A mobile station notifies the base station of a second mode supported by the mobile station, receives, after the notification, the first information and the second information from the base station, and skips without decoding as much downlink resource allocation information as a length corresponding to the length information without decoding, if the first mode is different from the second mode.

摘要:
An apparatus and method for controlling a sleep mode in a wireless access communication system. The apparatus determines a predetermined number of groups for grouping at least one subscriber terminal according to type information of a paging interval equal to the sum of the sleep interval and the listening interval, and registers the subscriber terminal in one group from among the groups on the basis of the paging interval type of the subscriber terminal. Upon receipt of the group information, the apparatus controls a base station to pre-recognize a terminal woken up at a predetermined time from among a plurality of terminals entering the sleep mode, resulting in reduction of the number of unnecessary paging message transmissions and improved efficiency of the wireless access communication system.
摘要:
A method and a system is disclosed for controlling a sleep mode in broadband wireless access communication system. The subscriber terminals are managed by grouping the subscriber terminals in a broadband wireless access communication system, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase. A further advantage is provided that each point of time for transmitting a paging message of each group is established differently from each other within a unit time slot for controlling the sleep mode, such that subscriber terminals are managed according to groups. Another advantage is provided that the base station can previously find subscriber terminals awaking at each point of time for transmission the paging message of each other from among subscriber terminals having the sleep mode, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase.

摘要:
A method for controlling an operation mode of a terminal in a broadband wireless access communication system. In the method, the operation modes of the terminal is subdivided, such that it is possible to effectively reduce power consumption of the terminal. In particular, the method allows the terminal to operate in the inactive mode in which the terminal having no traffic with a base station more than a predetermined time returns a CID of the terminal to the base station and keeps only a downlink with the base station, so that it is possible to prevent power of the terminal from being consumed during the sleep mode. Additionally, because a CID is not assigned to the terminal in the inactive mode, resources of the base station are efficiently used.

A method and apparatus for decoding the depth map of multi-view video data are provided. The method includes splitting a block of restored multi-view color video frame into a partition based on a pixel value of the block of the prediction-encoded and restored multi-view color video frame; obtaining a parameter indicating correlation between block partitions of the multi-view color video frame and block partitions of the depth map frame using peripheral pixel values of the block partitions of the multi-view color video frame and peripheral pixel values of the block partitions of the depth map frame corresponding to the block partitions of the multi-view color video frame with respect to each of the block partitions of the restored multi-view color video frame; and obtaining prediction values of corresponding block partitions of the depth map frame from the block partitions of the restored multi-view color video frame using the obtained parameter.

A substrate panel is disclosed. The substrate panel may include a clamp contact, a bus line formed at a distance from the clamp contact, and a plurality of substrate units supplied with an electric current by way of the bus line, where an insulation part may be formed between the clamp contact and the bus line, through which electricity may not flow.
