    摘要： Embodiments contemplate methods, systems, and apparatuses for interference measurement in a wireless communication network, including wireless communication networks the employ MIMO in uplink and/or downlink communication. Embodiments contemplate identifying one or more interference measurement resource elements that may be received from one or more transmission points. Embodiments also contemplate performing interference measurement estimation based at least in part on the identified one or more interference measurement resource elements. Channel state information (CSI) perhaps in the form of reports may be generated based at least in part on the one or more interference measurement estimation. Embodiments also contemplate that the CSI report may be transmitted to one or more nodes. In some embodiments, the one or more interference measurement resource elements may be received as part of a set of resource elements.

    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： Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePDCCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type subframe definition may also be provided and/or used for support of such a reduced bandwidth.
