摘要： A method and apparatus are disclosed for determining a signal subspace in a communications system. A remote apparatus obtains signal streams from antenna elements or signal streams from antenna beams. Based on the obtained signal streams, the apparatus selects a signal subspace for a user, the signal subspace having a dimension M. Based on the selected signal subspace, the apparatus transmits, via an interface to a central apparatus, M streams of post-fast-Fourier-transform data, the interface being capable of transmitting a different subspace for different frequency bins.

摘要： A first cell determines that UE(s) should have HARQ cycle(s) skipped, where each of the UE(s) is to take part in a CoMP transmission. Skipping is to be performed to enable the first cell to receive information from second cell(s) over backhaul link(s) for the HARQ transmission(s). A first HARQ cycle is scheduled and participated in for the UE(s) in order to receive a transmission at the first cell from the UE(s). The HARQ cycle(s) is/are skipped for the UE(s) by sending, prior to decoding information from the uplink CoMP transmissions, an acknowledgement to the UE(s) and not scheduling the UE(s) for a PDCCH grant for the HARQ cycle(s). The skipping depends on one or more of: a backhaul latency, a load in the first cell, a type of UE, or a request to the second cell(s). Apparatus and program products are also disclosed.

摘要： Systems and techniques for managing helper cells in coordinated multipoint processing. Bandwidth assistance is requested from one or more cells operating in a network. In response to demand price and headroom information provided by a plurality of cells receiving the request, a set of potential helper cells is rank ordered and identified one or more helpers is identified from the ordered set and a candidate helper set is assembled based on bandwidth performance assistance criteria. A new request for bandwidth assistance is made. In response to new demand price and headroom information obtained from the candidate helper set, a determination is made whether sufficient iterations have been performed. If sufficient iterations have not been performed, the process is repeated, and if sufficient iterations have been performed, a requesting cell proceeds to operate while receiving bandwidth assistance from the assembled set.
