Abstract: Devices and methods of determining offsets for different eNBs in a dynamic switched CoMP network are generally described. A UE may receive, in an RRCConnectionReconfiguration message, DL parameter sets associated with different eNBs and having reference signal information for a PSS, SSS and DRS. The UE may receive reference signals based on the DL set associated with the eNB and determine a timing/frequency offset based on the reference signals. The offsets may be used to decode a dynamically switched PDSCH indicated by a PDCCH. The DL sets may indicate which PDCCH to detect or the PDCCH from the same eNB may be used and the PDSCH determined from a DCI in the PDCCH. A UL DCI may indicate which of UL parameter sets to use. The UL sets may indicate a reference signal to determine path loss and a timing advance value.

Abstract: Systems and technologies described herein provide functionality for a cellular base station to dynamically indicate a reception (Rx) beam to be used by a user equipment (UE). The Rx beam can be indicated explicitly or implicitly. The UE can, for example, use the Rx beam for Physical Downlink Shared Channel (PDSCH) reception, Channel State Information Reference Signal (CSI-RS) measurements, and/or Channel State Information (CSI) calculation at the UE. Systems and technologies described herein are generally useful for systems that use multiple transmission (Tx) beams and/or that support Coordinated Multipoint (CoMP) transmission technology.
