Abstract: An apparatus is provided for efficiently allocating a transmission period in a WLAN system. An access point (AP) transmits a PSMP message providing a downlink period and an uplink period provided to each station (STA), and at least one sub PSMP frame indicating a period of at least one of a downlink and an uplink for an STA requiring additional resource allocation. After exchanging data with the AP in the downlink and uplink periods provided by the PSMP frame, if there is a need for additional resource allocation, the STA receives the at least one sub PSMP frame and exchanges data with the AP in the period provided by the each sub PSMP frame.

Abstract: A polishing pad of a CMP apparatus has a plurality of pores. A characteristic associated with the pores, such as average size or pore density, varies substantially from region to region of the pad across the pad in a diametral direction of the pad. The polishing pad can be designed and manufactured using sample pads whose pore characteristics differ from each other. CMP test processes are performed in which the sample pads are used to polish test wafers, and the rates at which the test wafers are polished are measured and stored in a database. The polishing pad is fabricated using data from the database so that a chemical mechanical polishing apparatus employing the pad will polish wafers with a high degree of uniformity. The database can be used to select sample pads from a stockpile. Sections of the sample pads are cut out, respectively, and fastened to one another.

Abstract: Disclosed is a method for configuring a bitmap in a mobile communication system employing a block ACK scheme, which faithfully performs its intrinsic function of acknowledging a reception result, and yet can reduce transmission delay and the overall system load due to retransmission in the case where packet loss is relatively less important than transmission delay time, such as in the case of voice communication. To this end, a recipient compares a PER of a received packet signal with a threshold value. If the PER is higher than the threshold value, the recipient operates in the block ACK scheme, and if the PER is lower than the threshold value, the recipient determines a bitmap configuration scheme on the assumption that an erroneous frame has been successfully received. Also, using the determined bitmap configuration scheme, the recipient transmits a reception result for each received packet.

Abstract: A digital multimedia broadcasting (DMB) system and conditional access method for regionally limiting DMB reception. A DMB station collects information about location of a DMB receiving terminal when a broadcast channel with regional conditional access features is being broadcast. According to the current location of a DMB receiving terminal, the DMB station checks subscribers whose reception of the broadcast channel with the regional conditional reception features is limited. The DMB station includes reception restriction information for limiting the reception of the broadcast channel in subscriber entitlement information of subscribers. The DMB receiving terminal descrambles and outputs a transport stream (TS) packet of the broadcast channel according to the received subscriber entitlement information. Therefore, the reception of a specific broadcast channel can be limited according to location of a user of the DMB receiving terminal.

Abstract translation: 数字多媒体广播（DMB）系统和区域限制DMB接收的条件访问方式。 当正在广播具有区域条件访问特征的广播频道时，DMB站收集关于DMB接收终端的位置的信息。 根据DMB接收终端的当前位置，DMB站对具有区域条件接收特征的广播频道接收受限的用户进行检查。 DMB站包括用于限制用户的用户授权信息中的广播频道的接收的接收限制信息。 DMB接收终端根据接收到的用户授权信息解扰并输出广播信道的传输流（TS）分组。 因此，可以根据DMB接收终端的用户的位置来限制特定广播频道的接收。
