Abstract
Embodiments contemplate methods and systems for determining and communicating channel state information (CSI) for one or more transmission points (or CSI reference signal resources). Embodiments further contemplate determining transmission states may include applying at least one CSI process for channel state information (CSI) reporting. Embodiments also contemplate aperiodic and/or periodic reporting of one or more report types (e.g., rank indicator (RI)) of CSI, perhaps based on one or more reporting modes that may be configured for each of the one or more CSI process.
Claims20
A wireless transmit/receive unit (WTRU) comprising:
- a processor configured to:
- receive first configuration information indicating a first set of non-zero power (NZP) channel state information reference signal (CSI-RS) resources and a first set of CSI interference measurement (CSI-IM) resources;
- receive second configuration information indicating a second set of NZP CSI-RS resources and a second set of CSI-IM resources;
- perform a first set of one or more measurements using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- perform a second set of one or more measurements using the second set of NZP CSI-RS resources and the second set of CSI-IM resources;
- receive a first trigger indicating that a first aperiodic CSI report is to be transmitted by the WTRU, the first trigger indicating that the first aperiodic CSI report is to be based on measurements performed using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- send the first aperiodic CSI report including at least a first measurement value determined based on the first set of one or more measurements performed using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- receive a second trigger indicating that a second aperiodic CSI report is to be transmitted by the WTRU, the second trigger indicating that the second aperiodic CSI report is to be based on measurements performed using the second set of NZP CSI-RS resources and the second set of CSI-IM resources;
- and
- send the second aperiodic CSI report including at least a second measurement value determined based on the second set of one or more measurements performed using the second set of NZP CSI-RS resources and the second set of CSI-IM resources.

- receiving second configuration information indicating a second set of NZP CSI-RS resources and a second set of CSI-IM resources;
- performing a first set of one or more measurements using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- performing a second set of one or more measurements using the second set of NZP CSI-RS resources and the second set of CSI-IM resources;
- receiving a first trigger indicating that a first aperiodic CSI report is to be transmitted by the WTRU, the first trigger indicating that the first aperiodic CSI report is to be based on measurements performed using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- sending the first aperiodic CSI report including at least a first measurement value determined based on the first set of one or more measurements performed using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- receiving a second trigger indicating that a second aperiodic CSI report is to be transmitted by the WTRU, the second trigger indicating that the second aperiodic CSI report is to be based on measurements performed using the second set of NZP CSI-RS resources and the second set of CSI-IM resources;
- and
- sending the second aperiodic CSI report including at least a second measurement value determined based on the second set of one or more measurements performed using the second set of NZP CSI-RS resources and the second set of CSI-IM resources.

A base station comprising:
- a transceiver;
- and
- a processor configured to:

- send, via the transceiver to the WTRU, second configuration information indicating a second set of NZP CSI-RS resources and a second set of CSI-IM resources;
- send, via the transceiver to the WTRU, a first trigger indicating that a first aperiodic CSI report is to be transmitted by the WTRU, the first trigger indicating that the first aperiodic CSI report is to be based on measurements performed by the WTRU using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- receive, via the transceiver from the WTRU, the first aperiodic CSI report including at least a first measurement value determined based on the first set of one or more measurements performed using the first set of NZP CSI-RS resources and the first set of CSI-IM resources;
- send, via the transceiver to the WTRU, a second trigger indicating that a second aperiodic CSI report is to be transmitted by the WTRU, the second trigger indicating that the second aperiodic CSI report is to be based on measurements performed by the WTRU using the second set of NZP CSI-RS resources and the second set of CSI-IM resources;
- and
- receive, via the transceiver from the WTRU, the second aperiodic CSI report including at least a second measurement value determined based on the second set of one or more measurements performed using the second set of NZP CSI-RS resources and the second set of CSI-IM resources.
