Interference measurement in wireless networks

摘要

Embodiments contemplate methods, systems, and apparatuses for interference measurement in a wireless communication network, including wireless communication networks the employ MIMO in uplink and/or downlink communication. Embodiments contemplate identifying one or more interference measurement resource elements that may be received from one or more transmission points. Embodiments also contemplate performing interference measurement estimation based at least in part on the identified one or more interference measurement resource elements. Channel state information (CSI) perhaps in the form of reports may be generated based at least in part on the one or more interference measurement estimation. Embodiments also contemplate that the CSI report may be transmitted to one or more nodes. In some embodiments, the one or more interference measurement resource elements may be received as part of a set of resource elements.

主权项

1. A wireless transmit/receive unit (WTRU) comprising:
a processor, the processor configured at least with:
one or more channel state information (CSI) interference measurement (CSI-IM) resources, each of the one or more CSI-IM resources including a set of one or more interference measurement resource elements, the one or more CSI-IM resources configured to measure energy considered as interference energy, the interference energy including Physical Downlink Shared Channel (PDSCH) energy;one or more non-zero-power CSI reference signal (CSI-RS) resources, the non-zero-power CSI-RS resources configured to measure energy considered as signal energy; andone or more CSI processes, each of the one or more CSI processes corresponding to a CSI measurement associated with one of the one or more non-zero power CSI-RS resources and with one of the one or more CSI-IM resources; and a receiver, the receiver configured at least to:
receive one or more measurements of the PDSCH energy in the one or more interference measurement resource elements.
