    Abstract: Described herein is a silent period method and apparatus for dynamic spectrum management. The methods include configuration and coordination of silent periods across an aggregated channel in a wireless communication system. A silent period management entity (SPME) dynamically determines silent period schedules for channels based on system and device information and assigns a silent period duration and periodicity for each silent period. The SPME may reconfigure the silent period schedule based on system delay, system throughput, channel quality or channel management events. A silent period interpretation entity (SPIE) receives and implements the silent period schedule. The silent periods for the channels may be synchronized, independent, or set-synchronized. Interfaces for communicating between the SPME, SPIE, a channel management function, a medium access control (MAC) quality of service (QoS) entity, a sensing/capabilities database, a MAC layer management entity (MLME) and a wireless receive/transmit unit (WTRU) MLME are described herein.

    Abstract: A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.

    Abstract translation: 动态频谱管理（DSM）引擎可以在不通过信道发送分组时确定与DSM引擎相关联的一个或多个信道的信道质量。 例如，DSM引擎可以在从与非主信道相关联的最后活动经过预定时间段的情况下在非主信道上触发信道质量测量。 信道质量测量可以通过非主信道上的数据发送事件来触发，例如在非主信道上发送数据帧。 DSM引擎可以对多个通道执行相应的质量测量，并将相应的质量值存储在数据库中。 可以基于用于计算跨信道的发射功率分布的存储的质量值来计算信道的时间平均信道质量。

    Abstract: Systems and methods are described generally related to the creation of a spectrum allocator (SA) function that can be used to dynamically assign/reassign the frequency of operation of a node operating in a wireless communication network. To permit LTE operation in license exempt (LE) bands, the radio resource management (RRM) system is enhanced to include an interface, which allows it to communicate with modules external to the RRM, such as a coexistence manager, policy engine and sensing toolbox.

    Abstract: A wireless transmit/receive unit (WTRU) may include one or more antennas and a first transceiver operatively coupled to the antennas. The one or more antennas and the first transceiver may be configured to receive a first signal from a network using zero energy from the WTRU. The one or more antennas and the first transceiver may be further configured to extract energy from the first signal. The first transceiver may be further configured to examine a separation between energy threshold events to decode an energy signature of the first signal. The first transceiver may be further configured to activate a second transceiver operatively coupled to the one or more antennas if the decoded energy signature matches a stored energy signature, wherein the second transceiver is powered by the WTRU. The one or more antennas and the second transceiver may be configured to receive a second signal from the network.
