摘要： Channel state information is reported in periodic and aperiodic reports for multiple component carriers or serving cells. Channel state information may be reported for a subset of aggregated downlink carriers or serving cells. For an aperiodic report, the carrier(s)/serving cell(s) for which channel state information is reported may be determined based on the request for the aperiodic report. A report collision may occur in a subframe between a periodic CSI report for a first serving cell and a report for a second serving cell. A priority rule may be used to resolve the report collision.

摘要： Methods and apparatus for preventing physical hybrid automatic repeat request (HARQ) indicator channel (PHICH) ambiguities or collisions, for example, in a multi-carrier system or when transmitting multiple streams over multiple antennas, are described. Methods may include dividing resources or groups among multiple component carriers (CCs), using and assigning unused or vacant resources to CCs, forcing usage of adaptive HARQ processes in specified scenarios, setting a value for the cyclic shift of the corresponding uplink demodulation reference signals (DMRS) to a previous value for semi-persistent scheduling, and assigning a different first resource block for semi-persistent scheduling uplink resources and random access response grants for multiple CCs.

摘要： Systems and methods for managing and/or improving interference in cells may be provided. For example, in embodiments, a partial-band Almost Blank Subframe (PB-ABS) subframe and/or a spatial Almost Blank Subframe (SABS) may be provided and/or used for coordinating communication with in networks with smaller and larger cells (e.g. pico or macro cells). For example, a PB-ABS may provide a dimension (e.g. frequency) that may be used to define a region and/or particular resources (e.g. resource blocks) reserved for pico cell operations or transmissions and a region or other resources (e.g. not those reserved for pico cell operations) available for macro cell operations or transmissions. Additionally, based on beam parameters (e.g. associated with cell partitioning), SABS may offer an additional dimension (e.g. spatial) that may be used to prevent transmission in a particular spatial direction.

摘要： Methods, systems and apparatuses for operation in long-term evolution (LTE) systems are provided, including a method implemented by a wireless transmit/receive unit (WTRU) served by a cell, where an enhanced physical broadcast channel (ePBCH) may be sent by the cell and may including basic information for WTRU control. The method may include receiving, by the WTRU, the ePBCH, and demodulating the ePBCH based on a demodulation reference signal (DMRS). In some embodiments, demodulating the ePBCH may be based on any of: a primary synchronization signal (PSS), a secondary synchronization signal; and a cell-specific reference signal (CRS), as well. Also provided is a method implemented by a WTRU in a vicinity of a dormant cell. The method may include any of: receiving, from a dormant cell, a signal; receiving, from a serving cell, a trigger to initiate measurement of one or more dormant cells; and measuring the signal.

摘要： Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and UE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.
