Abstract: Systems, methods, apparatuses, and computer program products for utilizing uplink (UL) CoMP helper data are provided. One method includes setting, by a network node serving a user equipment, a priority for a helper data request of an uplink transmission of the user equipment. The setting may include setting the priority based on a specific history of the user equipment. The method may also include sending the helper data request to another network node and, optionally, sending the priority set for the helper data request to said another network node.

Abstract: Achieving phase synchronization in single frequency networks may be useful in various communication systems. For example, the use of synchronous Ethernet, timing over packet, and radio interface based synchronization (RIBS) may be applied in mobile and/or data communication networks. Certain embodiments improve phase accuracy using a hybrid synchronization method beyond standard RIBS and clustering carriers using the same transmission waveforms across carriers. Certain embodiments also select a master transmission point to maximize the signal quality of the composite waveforms in a cluster.

Abstract: An apparatus and method for antenna selection in uplink coordinated multipoint communications, where a plural number of geographically separated antennas are present, forming a plural number of cells. This apparatus and method relates to selecting a PRACH configuration, sharing information regarding the selected PRACH preamble amongst cells; an user equipment, upon receiving instruction from its serving cell, transmits a PRACH preamble. All cells, including serving cell, detects the selected PRACH preamble in the received PRACH transmission transmitted by the user equipment, determining pathloss information regarding the quality of the detected selected PRACH preamble, and selecting a set of cooperative multipoint antennas from the plural number of antennas based on the determined channel quality information for this user equipment. This apparatus and method is also applicable for antenna selection in the case of a single cell with a plural number of geographically separated antennas.

Abstract: An aggregation unit includes a transceiver configured to transmit unique signals to a plurality of transmission reception points (TRxPs) for transmission by the plurality of TRxPs and receive uplink signals received by the plurality of TRxPs from a user equipment. The aggregation unit also includes a processor configured to generate a sum of the uplink signals from a subset of the plurality of TRxPs. The subset is determined based on measurements of the unique signals performed by the UE. In some cases, the subset is determined by a baseband unit that receives a measurement report including the measurements performed by the UE. The transceiver is configured to transmit the sum of the uplink signals to the baseband unit over a fronthaul link.

Abstract: Various communication systems may have various mechanisms for handling data loss. For example, certain wireless communication systems may benefit from appropriate handling of uplink coordinated multipoint helper data loss on a subset of symbols within a transmission time interval. A method can include receiving helper data corresponding to a portion of an uplink subframe. The method can also include performing coordinated multipoint processing on the portion of the uplink subframe using the helper data.
