UPLINK COORDINATED MULTI-POINT

摘要

Disclosed embodiments may include an apparatus having one or more processors coupled to one or more computer-readable storage media. The one or more processors may be configured to transmit and/or receive channel state information reference signal (CSI-RS) resource configuration information, demodulation reference signals (DM-RS), uplink sounding reference signals (SRS), and power control parameters to support uplink coordinated multi-point (CoMP) operations. Other embodiments may be disclosed.

主权项

1. One or more computer readable media having instructions thereon that, in response to execution by one or more processing devices of a user equipment (UE), cause the UE to:
determine a physical layer cell identity corresponding to a cell of an evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN); receive an indicator of a virtual cell identity via radio resource control signaling, the virtual cell identity different from a physical layer cell identity corresponding to a cell of an evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN); receive a cyclic shift hop initialization value different from the virtual cell identity; and generate a demodulation reference signal (DM-RS) parameter based at least in part on the virtual cell identity, and generate a cyclic shift for a DM-RS by initializing a pseudo-random sequence generator with the cyclic shift hop initialization value.
