摘要： A first wireless node may synchronize its timeslots with the timeslots of a second wireless node that was previously transmitting and receiving data in an asynchronous manner with respect to the timeslots of the first wireless node. By synchronizing timeslots, the wireless nodes may avoid interference that may otherwise occur if the wireless nodes operate in an asynchronous manner. A wireless node shares its timing information with other wireless nodes by repeatedly transmitting timing reference signals in conjunction with a synchronization metric that defines the relative priority of the timing reference. In the event a wireless node does not receive a GPS-based timing reference, the wireless node may synchronize to a timing reference based on the parameters of the synchronization metric of that timing reference. In the event a wireless node does not receive any timing references, the wireless node may define and advertise it's a timing reference and associated synchronization metric. To avoid synchronization race conditions, the synchronization metrics may be defined such that wireless nodes that have different timing references will advertise different synchronization metrics.
摘要翻译：第一无线节点可以将其时隙与先前以相对于第一无线节点的时隙的异步方式发送和接收数据的第二无线节点的时隙同步。通过同步时隙，无线节点可以避免无线节点以异步方式操作时可能发生的干扰。无线节点通过与定义定时参考的相对优先级的同步度量重复地发送定时参考信号，与其他无线节点共享其定时信息。在无线节点不接收基于GPS的定时参考的情况下，无线节点可以基于该定时参考的同步度量的参数来同步到定时参考。在无线节点没有接收任何定时参考的情况下，无线节点可以定义并通告它是定时参考和相关联的同步度量。为了避免同步竞争条件，可以定义同步度量，使得具有不同定时参考的无线节点将通告不同的同步度量。

摘要： In a first method, a first apparatus determines a channel gain to a second apparatus with which the first apparatus is communicating. The first apparatus determines interferer backoff information that ensures an interference level at the first apparatus such that a signal received from the second apparatus can be decoded reliably. The interferer backoff information is determined based on the channel gain. The first apparatus transmits information based on the interferer backoff information in a message to the second apparatus. In a second method, a first apparatus in communication with a second apparatus determines a channel gain to a third apparatus with which the first apparatus can potentially interfere. The first apparatus receives a message from the third apparatus. The message includes interferer backoff information. The first apparatus determines a power for transmitting a signal to the second apparatus based on the interferer backoff information and the channel gain.

摘要： In a wireless communication system, there is a method of generating and transmitting signaling information from a user, where user control information may be appended as a header to a data block, and the data block and header may be encoded and transmitted as a signaling message from the user. In a method of scheduling a user for transmitting information, a signaling message, which may include user control information, is received from a user. A scheduling grant message that may include an allocated data rate may be transmitted in response to the received signaling message. The user control information may include one or more of buffer status information of the user, reverse pilot channel transmit power information and data related to a soft handoff (SHO) status of the user.

摘要： Chase combining gains for receiving a scrambled broadcast channel can be achieved even when a portion of each received channel coded transmission contains a portion that varies. A set of possible difference values for this varying portion, such as for a system frame number, provides hypotheses, each having a corresponding probability. One or more of the hypotheses are selected by rank order for adjusting a corresponding received coded transmission so that two or more channel coded transmissions can be combined and blind decoded until one of the hypotheses are confirmed.

摘要： Systems and methodologies are described that facilitate adapting wireless device scheduling parameters at least in part by adjusting prioritized bit rates (PBR) of one or more logical channels. The PBRs can be adjusted according to feedback from a media access control layer scheduler or a radio link control layer regarding resource allocations to one or more wireless device, served rate for one or more wireless device, and/or the like. Adjusting the PBRs based on the feedback can increase likelihood that data can be transmitted over substantially all or a specified set of logical channels. Moreover, PBRs can be modified for specific wireless devices based further on resource allocations thereto. Furthermore, PBRs can be modified based at least in part on radio conditions of neighboring access points.
