  • eNB 901 may select several CSI-RS resources whose RSRP and/or RSRQ are above predefined thresholds. eNB 901 may then define one or more selected CSI-RS resources as rank-1 CSl processes. Based upon multi-stream data reception capabilities of UE 902, and based upon its own analog beamformer capabilities, eNB 901 may create one or more groups of selected CSI-RS resources. Each group of CSI-RS resources may be termed a CSI-RS process. A number of CSI-RS resources in the CSI-RS process may define a rank of the CSl process. CSI-RS resources in the CSI-RS process with rank greater than 1 may be allocated with different time-frequency resources. However, channels experienced by the CSI-RS resources may be quasi-static within the same instance of the CSI process.

  • eNB 901 may repeat earlier actions and reconfigure CSI processes for the UE.
  • UE 902 may be configured with several CSI processes of either rank-1 or rank-2. These CSI processes may be transmitted from different mmWave eNBs. Some rank-2 CSI processes may include CSI-RS resources from two or more different eNBs. In such cases, the quasi co-location assumption of different CSI-RS ports in the same CSI processes may not hold. However, quasi co-location between a CSI-RS resource in a CSI process and a CSI-RS based discovery signal may be added to improve channel estimation performance.

  • An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.
