Abstract: Systems and methods for enabling precoding diversity in the time domain are provided. In some embodiments, a User Equipment (UE) includes circuitry including a processing module and a memory module configured to receive an indication that a physical channel is repeated over a set of subframes and receive an indication that the UE can assume that a first subset of the repetitions of the physical channel and a reference signal will use a first precoder. In this way, in some embodiments, the UE can coherently combine the repetitions, including the reference signals used by the physical channel. The ability to coherently combine repetitions of the physical channel may improve both the estimates of the physical channel as well as channel estimates derived from the repeated reference signals.

In some embodiments, a base station of a cellular communications network disables inter-subframe channel interpolation of CSI-RS estimates across subframes at the wireless device and receives one or more CSI reports from the wireless device that are generated by the wireless device with inter-subframe channel interpolation of C SI-RS estimates across subframes disabled in response to the base station disabling inter-subframe channel interpolation of CSI-RS estimates across subframes at the wireless device. In this manner, CSI feedback is improved particularly in embodiments in which the base station transmits a beamformed CSI-RS resource(s) and reuses the same CSI-RS resource(s) for different beams over time.

Abstract: A communication system provides, via a single, serving Node B, scheduling information required by a user equipment (UE) to determine a start time for each Node B of multiple Node Bs with respect to a multicast, by each Node B of the multiple Node Bs, of soft combinable MBMS data. The UE may then use the scheduling information to synchronize a soft combining of the MBMS data received by the UE via each of the multiple Node Bs, even when the multicasts via the multiple Node Bs are not synchronized. However, while the multicasts of frames of data associated with an MBMS service by different Node Bs need not be synchronized, synchronized multicasts are preferable for soft combining. Therefore, the communication system further provides for a synchronization by a network controller of the multicasts of the soft combinable MBMS data by the multiple Node Bs.
