摘要： In the system acquisition process system information is non-coherently detected using correlation of reconstructed and received preamble signals, such as the primary broadcast control channel (PBCCH) and the acquisition pilots (TDM1, TDM2, and TDM3). The phase correlation signals between the correlated signals of PBCCH and TDM2 or TDM3 and between the correlated signals of TDM2 and TDM3 are combined to decode other sector interference (OSI) information and the like. Acquisition is also made more efficient by taking advantage of predictable information based on system synchronicity. The sync/async bit is included in at least one of the acquisition pilots. The mobile then uses knowledge of system synchronicity to more efficiently detect the additional information in the superframe preamble.

摘要： Two types of access probe messages are defined: a first when a mobile station has not yet been assigned a media access code index (MAC ID), and a second when a mobile station already has a MAC ID assigned by the base stations in the active set. Base stations can differentiate between the first and second types of access probes according to the scrambling sequence used. In the second type, while different MAC IDs are used by each of the mobile stations in the sector, they are all scrambled according to a similar scrambling sequence defined specifically for these second types of access probes. The rake receivers used in such networks are configured to repeat the rake finger processing after CP removal, DFT, de-channelizing, and IDFT, thereby reducing their complexity.
摘要翻译：定义了两种类型的接入探测消息：首先当移动台尚未分配媒体接入码索引（MAC ID）时，另一种类型的接入探测消息，当移动台已经具有由活动的基站分配的MAC ID时组。基站可以根据所使用的加扰序列区分第一和第二类型的接入探测器。在第二种类型中，虽然扇区中的每个移动站使用不同的MAC ID，但是它们都是根据为这些第二类型的接入探针专门定义的类似的加扰序列而被加扰的。在这种网络中使用的耙式接收机被配置为在CP去除，DFT，去通道化和IDFT之后重复耙指处理，从而降低它们的复杂性。

摘要： A base station transmits control information to a mobile station. A first control channel is transmitted to the mobile station. The first control channel contains an indication of the number of control channel occurrences in a frame. A second control channel is transmitted to the mobile station in a control subframe. The second control channel contains information for communicating a packet between the base station and the mobile station. The control subframe is determined from the number of control channel occurrences in the frame. The packet can then be communicated between the base station and the mobile station in a subframe based on the control channels transmitted.

摘要： A system and method for transmitting and error handling control feedback information is provided. A method for error handling in a transmission of control feedback information over a communications link by a first station includes determining a first feedback information at the first station, transmitting the first feedback information at a first instance to a second station, and receiving a scheduling message from the second station. The scheduling message includes a second feedback information, and the second feedback information is based on the first feedback information. The method also includes determining if the first feedback information at the first instance was received correctly by the second station based on the scheduling message, and in response to determining that the first feedback information at the first instance was not received correctly by the second station, transmitting the first feedback information at a second instance to the second station.

摘要： A system providing flexible cyclic prefix length in a preamble (i.e., superframe preamble) is disclosed. The preamble comprises a first section and a second section. The first section contains at least one broadcast channel and occupies the first number of OFDM symbols in the preamble. The second section contains acquisition pilots and occupies the remaining number of OFDM symbols in the preamble. A first cyclic prefix length is used in the first section. It is indicated by the first broadcast channel and is unknown to a mobile station before the mobile station decodes the first broadcast channel. The second cyclic prefix length is used in the second section. It is fixed and known to the mobile stations. The first broadcast channel is located at the last OFDM symbol in the first section and is next to the second section in time.
