Abstract: A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

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 digital baseband (DBB) radio frequency (RF) receiver includes a digital high pass filter compensation (HPFC) module used to suppress group delay variation distortion caused by using low cost analog high pass filters (HPFs) in the receiver. The digital HPFC module reduces a cutoff frequency, established by the HPFs for the real and imaginary signal component frequency domain responses by providing a first compensation signal having a first predetermined value (K 1 ). The digital HPFC module adjusts the gain of the high pass response of the real and imaginary signal component frequency domains by providing a second compensation signal having a second predetermined value (K 2 ).

Abstract: A method and apparatus are described for synchronizing a network. A plurality of existing nodes in the network may transmit beacons in accordance with a round-robin scheduling sequence. A new joining node may receive a beacon from a specific one of the existing nodes during a beacon interval, and transmit a join beacon frame during the beacon interval after waiting a random period of time. The specific existing node may receive the join beacon frame and transmit a notification to the other existing nodes in the network indicating that a new node is joining the network. Alternatively, the existing nodes may transmit a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). After a new node receives the PSS and SSS from a specific one of the existing nodes, the new node may generate a random access channel (RACH) preamble indicating that it desires to join the network.

Abstract: A wireless transmit/receive unit (WTRU) and a dynamic spectrum management (DSM) engine are described. The WTRU includes a transceiver, a radio frequency (RF) spectrum sensing unit and a processing unit. The transceiver transmits over a wireless link. The RF spectrum sensing unit measures information indicative of usage of a spectrum by other devices. The processing unit detects a change in performance of the wireless link. The processing unit also controls the transceiver to transmit a notification to a DSM engine indicating that the change in the performance of the wireless link was detected on a condition that the processing unit detects the change in performance of the wireless link. The processing unit also receives a sensing task request for the WTRU to measure the information indicative of the usage of the spectrum by other devices based on the notification transmitted to the DSM engine indicating that the change in the performance of the wireless link was detected.

Abstract: A method and apparatus for a secondary wireless transmit/receive unit (WTRU) to use of secondary cellular spectrum are provided. The secondary WTRU monitors transmissions of a primary WTRU; determines whether to provide assistance to the primary WTRU; and in response to a determination to provide assistance, performs cooperative communications with the primary WTRU for its transmission of data to a base station. If the assistance results in the data being transmitted to the base station faster than it would have with out assistance, the secondary WTRU may utilize uplink resources originally intended for the primary WTRU.
