    • Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an "out of synch' counter and/or the radio link failure (RLF) timer used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.
    • 描述了减轻设备内干扰的方法和装置。 这些方法可以包括设备内干扰事件(例如干扰情况),并且事件的处理可以取决于技术的优先级。 在共同存在的技术可能被激活的情况下,可能发生切换到另一频率或无线电接入技术(RAT)。 网络可以向设备发送可能被允许测量和切换到的频率或RAT的列表。 网络可以提供设备可用于加速对干扰的反应的缩放值。 该设备可以将缩放因子应用于用于RLF过程的“同步”计数器和/或无线电链路故障(RLF)定时器,该设备可以对测量和时间应用不同的缩放因子以触发事件。 可以触发对网络的报告,请求替代RAT的间隙。

    • Method and apparatus are disclosed for optimizing Random Access Channel (RACH) transmissions from wireless transmit/receive units (WTRUs) for multiple transmissions. A WTRU may initiate uplink transmission for a random access procedure using a configured time resource such that the uplink resources may be time shared by a plurality of WTRUs. The transmission time may be calculated on an absolute or relative basis. A backoff time may be applied before starting the uplink transmission. The backoff time may be WTRU-specific, WTRU group-specific, specified per access class and may be determined based on a priority basis. A scaling factor may be applied to the backoff time. A contention free allocation method may be used to determine the appropriate resource. The data may be transmitted with and without a preamble. The WTRUs may include machine type communication devices and may be grouped in accordance with a number of factors or characteristics.
    • 公开了用于针对多次传输优化来自无线发射/接收单元(WTRU)的随机接入信道(RACH)传输的方法和装置。 WTRU可以使用配置的时间资源来发起针对随机接入过程的上行链路传输,使得上行链路资源可以由多个WTRU时间共享。 传输时间可以基于绝对或相对计算。 在开始上行链路传输之前可以应用退避时间。 退避时间可以是WTRU特定的WTRU组特定的,每个接入等级指定并且可以基于优先级来确定。 缩放因子可以应用于退避时间。 可以使用无竞争分配方法来确定适当的资源。 数据可以在有和没有前导码的情况下传输。 WTRU可以包括机器类型通信设备,并且可以根据多个因素或特性来分组。

    • A method and system for distributing data to at least one communication device are disclosed. When multiple communication devices request the same data, a seeder sends a different piece of the data to each communication device and the communication devices share the piece of data each other by using a wireless connection established between them. The communication devices automatically suspend and resume downloading of the piece of the data from other communication devices as the communication device performs a handover. The receiver may be given super-distribution rights. When a destination communication device requests data, a content provider identifies a source communication device which possesses the same data and has the source communication device to forward the data to the destination communication device. The source communication device re-encrypts the data with a new encryption key and the destination communication device obtains a license from a rights issuer to decrypt the data.
    • 公开了一种用于向至少一个通信设备分发数据的方法和系统。 当多个通信设备请求相同的数据时,播种机向每个通信设备发送不同的数据片段,并且通信设备通过使用它们之间建立的无线连接来共享该数据片。 当通信设备执行切换时,通信设备自动暂停并继续从其他通信设备下载该数据。 接收机可能被赋予超级分配权限。 当目的地通信设备请求数据时,内容提供商识别具有相同数据的源通信设备,并且具有源通信设备以将数据转发到目的地通信设备。 源通信设备使用新的加密密钥重新加密数据,并且目的地通信设备从权限发布者获取许可证以对数据进行解密。
