Abstract: Coexistence gaps may permit one radio access technology (RAT) to coexists with another RAT by providing period in which one RAT may be silent and another may transmit. Methods may account for the RAT traffic and for the presence of other secondary users in a channel. Methods may be provided to dynamically change the parameters of a coexistence gap pattern, such as the duty cycle, to adapt to both the RAT traffic and the presence of other secondary users. Methods may include PHY methods, such as synchronization signal (PSS/SSS) based, MIB based, and PDCCH based, MAC CE based methods, and RRC Methods. Measurements may be provided to detect the presence of secondary users, and may include reporting of interference measured during ON and OFF durations, and detection of secondary users based on interference and RSRP/RSRQ measurements.

Abstract: A method for sensing measurement gap scheduling includes allocating a new supplementary carrier in a license-exempt spectrum by a radio resource management (RRM) entity in an evolved Node B (eNB); configuring a local cognitive sensing entity in the eNB by the RRM entity; configuring a wireless transmit/receive unit (WTRU) for cognitive sensing through radio resource control (RRC) signaling, the RRC signaling being generated by the eNB; configuring a local cognitive sensing entity at the WTRU by a dynamic spectrum management (DSM) entity; and signaling a start and a duration of a measurement gap to an enhanced sensing component.

Abstract: An iterative turbo decoder for a wireless transmit receive unit (WTRU) of a wireless communication system and method for error correcting received communication signal data are provided. The decoder implements a stopping rule through use of signature codes to determine whether successive iterations of decoder data are the same.

Abstract: Embodiments contemplate a wireless transmit/receive unit (WTRU) that may operate in a heterogeneous wireless communication network (HetNet). The WTRU may detect the presence of an extended physical downlink control channel (E-PDCCH) and may decode a physical downlink control channel (PDCCH) upon detecting the E-PDCCH. The WTRU may obtain scheduling information of the E-PDCCH on a physical downlink shared control channel (PDSCH) from the decoded PDCCH. The WTRU may also determine control information for the WTRU from the E-PDCCH using the scheduling information of the E-PDCCH. The HetNet may further include a first eNB and a second eNB and the WTRU may receive the E-PDCCH from the first eNB and another E-PDCCH from the second eNB. The other E-PDCCH may be coordinated with the E-PDCCH such that the interference between the other E-PDCCH and the E-PDCCH from the perspective of the WTRU may be reduced relative to no coordination.
