Abstract: A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station. The method may also include receiving a ranging response message from the base station. The method may also include determining whether a ranging failure condition is satisfied. The ranging failure condition may relate to something other than a duration of time. The method may further include re-sending the ranging code to the base station if the ranging failure condition is satisfied.

Abstract: A radiation detection method and apparatus thereof for estimating radiation power received by the mobile station. The locations of nearby base stations and the mobile station are obtained from the broadcast system messages and the location service provided by the service provider, and based on the location information, the radiation power is estimated according to the distances between the base stations and the mobile station. In addition, the radiation estimation process also utilizes the radiation power of monitored base stations constantly measured by the mobile station for cell selection to determine the effects of interference. Based on a preset safety value and the estimated radiation power, the radiation detection device of the present invention automatically issues an alert when entering a high radiation environment.

The aliasing module is defined and connected to alias the first bit stream as a second bit stream and transmit the second bit stream over the data bus in lieu of the first bit stream. A de-aliasing module is defined and connected to receive the second bit stream from the data bus at the external controller. The de-aliasing module is defined and connected to de-alias the received second bit stream back to the first bit stream and provide the first bit stream to the external controller for processing.

Abstract: A base station (BS) may determine a fixed modulation scheme, a fixed PDU payload size, and a fixed number of PDUs per downlink burst for transmission of multicast data to subscriber stations. The BS may allocate downlink bursts to deliver the multicast data to the subscriber stations via PDUs using the fixed modulation scheme, the fixed PDU payload size, and the fixed number of PDUs per DL burst. A subscriber station (SS) may bypass the processing of multicast frames if the SS does not belong to any multicast groups. An SS may search for multicast connection identifiers (CIDs) in DL MAP IEs in multicast frames if the SS belongs to at least one multicast group. The SS may bypass the parsing of a PDU's MAC header within a corresponding downlink burst in the multicast frame in response to identifying a multicast CID in a DL-MAP IE in a multicast frame.

Abstract translation: 基站（BS）可以确定固定调制方案，固定PDU有效载荷大小和每个下行链路突发的固定数量的PDU，用于向用户站传输多播数据。 BS可以分配下行链路脉冲串，以使用固定调制方案，固定PDU有效载荷大小和每DL突发的固定数目的PDU，经由PDU向用户站传送多播数据。 如果SS不属于任何多播组，则用户台（SS）可以绕过多播帧的处理。 如果SS属于至少一个多播组，则SS可以在多播帧中的DL MAP IE中搜索多播连接标识符（CID）。 响应于在多播帧中的DL-MAP IE中识别多播CID，SS可以绕过多播帧中的相应下行链路突发中的PDU的MAC报头的解析。

Abstract: A memory system includes a status circuit having a common status node electrically connected to a respective status pad of each of a plurality of memory chips. The memory system also includes a plurality of resistors disposed within the status circuit to define a voltage divider network for generating different voltage levels at the common status node. Each of the different voltage levels indicates a particular operational state combination of the plurality of memory chips. Also, each of the plurality of memory chips is either in a first operational state or a second operational state. Additionally, the different voltage levels are distributed within a voltage range extending from a power supply voltage level to a reference ground voltage level.
