    Abstract: A UE is configured with restrictions that restrict resources carrying RSs and IMRs to specific resources to be used by the UE for determining CSI. The restrictions are both of the following: first restrictions in time, frequency, or both time and frequency of resources that carry the reference signals; and second restrictions in time, frequency, or both time and frequency of resources that carry the interference measurement resources. The RSs and IMRs are transmitted by a base station to and received by the UE. The UE determines the CSI based on the specific resources for the RSs and IMRs. The CSI, determined based on the RS, IMRs, and the restrictions, is received from and transmitted by the UE. The base station uses the CSI for a MU-MIMO transmission. Apparatus, methods, computer software, and program products are disclosed.

    Abstract: Systems and techniques for joint transmission cooperative multi-point. A set of n CSI reference signal resources are to be measured by a user device. The n CSI reference signal resources include at least one CSI reference signal resource spanning over at least two transmission points. Channel state information feedback corresponding to each CSI reference signal resource is configured. Upon receiving CSI 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 CSI reference signal resource, the derivation including 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.

    Abstract: Various communication systems may benefit from managing signal interference. For example, certain wireless communication systems may benefit from a dynamic time division duplex system involving slot allocation. A method includes allocating, by an access point, in a time division duplex frame a plurality of radio resource slots, each one of the plurality of radio resource slots being allocated for a downlink or an uplink transmission, and determining that the allocation of the downlink or uplink transmission should be changed. The method also includes applying a permutation pattern to re-allocate at least one of the plurality of radio resource slots for the downlink or uplink transmission.
