Abstract: An authentication assurance level associated with an entity, for instance a user equipment, may be computed periodically or in response to an event. The authentication assurance level is compared to an authentication threshold. Based on the comparison, it is determined whether a fresh performance of at least one authentication factor needs to be performed. Thus, appropriate authentication factors and functions may be invoked on a periodic basis to maintain a certain authentication assurance level, which is referred to herein as the assurance threshold. The authentication assurance level may change, for instance decay, over time and may be refreshed periodically.

Abstract: A method and apparatus are described for controlling uplink (UL) transmission power. A wireless transmit/receive unit (WTRU) may receive a configuration of UL subframe sets and maintain a plurality of transmit power control (TPC) command accumulator values that correspond to respective ones of the UL subframe sets. The WTRU may receive a TPC command in a subframe n of a downlink (DL) transmission, determine a subframe n+k of a UL transmission that the received TPC command corresponds to, determine which of the UL subframe sets the UL transmission subframe n+k belongs to, and adjust a TPC command accumulator value that corresponds to the determined UL subframe set to determine power of the UL transmission when transmitting in the UL transmission subframe, where n is an integer, and k is an integer greater than zero.

Abstract translation: 描述了一种用于控制上行链路（UL）传输功率的方法和装置。 无线发射/接收单元（WTRU）可以接收UL子帧集合的配置，并且保持对应于UL子帧集合中的相应一个的多个发射功率控制（TPC）命令累加器值。 WTRU可以在下行链路（DL）传输的子帧n中接收TPC命令，确定接收到的TPC命令对应的UL传输的子帧n + k，确定UL子帧中的哪一个UL传输子帧n + k属于，并且调整与所确定的UL子帧集相对应的TPC命令累加器值，以在UL传输子帧中发送时确定UL传输的功率，其中n是整数，并且k是大于零的整数。
