摘要： A network access node/eNB selects one or more feedback modes for each of a plurality of channel state information reference signal CSI-RS resources so as not to exceed a predetermined maximum complexity; then configures a user equipment UE with them. Each CSI-RS resource is associated with a respective set of allowed feedback modes, and at least one of the sets has a fewer number of feedback modes than at least one other of the sets; for example the most complex feedback mode out of all possible feedback modes is excluded from the smaller set(s). An example formula is given for the predetermined complexity. If the UE receives a configuration that a) exceeds the maximum complexity, or b) configures a feedback mode for a given CSI-RS resource that is not in the respective associated set of allowed feedback modes, the UE can disregard the configuration as an error case.

摘要： Systems and techniques for joint transmission cooperative multi-point. A set of n channel state information reference signal resources are to be measured by a user device. The n channel state information reference signal resources include at least one channel state information reference signal resource spanning over at least two transmission points. Channel state information feedback corresponding to each channel state information reference signal resource is configured. Upon receiving channel state information from the user device, at least one precoder is selected for coherent joint cooperative multipoint transmission based on inter-transmission point phase relationship information. A co-phasing factor is derived from transmitted precoders over a cross-cell channel state information reference signal resource, the derivation comprising transmission of reference signals using first and second precoding vectors on two ports, computation of a third vector using feedback based on the precoded reference signals, and computation of the co-phasing factor based on the first, second, and third vectors.

摘要： Frequency resources for common control regions of a control channel are defined or determined as a function of at least bandwidth and an identifier of a specific cell. Communications between a wireless network and a mobile device are then done using the defined/determined frequency resources of the common control regions of the control channel. In the non-limiting embodiments: the bandwidth is bandwidth of a cell or of a component carrier; the frequency resources are defined/determined further as a function of an offset value; the common control regions are of an ePDCCH and the offset value differs from a channel edge offset value for common control regions of all other ePDCCHs of all other adjacent cells or all other transmit nodes in the same cell; and the frequency resources comprise frequency stripes (which may be interleaved by resource element groups) distributed in frequency across the bandwidth.
