Abstract

A wireless transmit/receive unit (WTRU) may receive first measurement indication information indicating an activation of measurement reporting. The WTRU may determine a first set of resource elements (REs) based on the first measurement indication information. Further, the first set of REs may be associated with measurement-related time and frequency resources. Also, the WTRU may receive one or more measurement-related signals in the indicated first set of REs. Additionally, the WTRU may perform a measurement of each measurement-related signal. The WTRU may transmit, based on the first measurement indication information, a measurement report based on the measurement of each measurement-related signal. Further, the WTRU may receive second measurement indication information indicating a deactivation of measurement reporting. Also, the WTRU may receive indication information regarding a plurality of sets of REs via radio resource control (RRC) signaling, including at least the first set of REs and a second set of REs.

Claims (35)

1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

receiving a radio resource control (RRC) message, the RRC message comprising configuration information indicating a set of one or more measurement-related signals, the set of one or more measurement-related signals being associated with a set of resource elements;

receiving a first indication, the first indication indicating that the set of one or more measurement-related signals associated with the set of resource elements has been activated;

receiving a second indication, the second indication indicating a request to report one or more measurements associated with the set of one or more measurement-related signals associated with the set of resource elements;

sending at least one measurement report based on receiving the second indication, the at least one measurement report comprising one or more measurement values determined based on one or more measurements of the set of one or more measurement-related signals associated with the set of resource elements; and

receiving a third indication, the third indication indicating that the set of one or more measurement-related signals associated with the set of resource elements has been deactivated.

2. The method of claim 1 , wherein the first indication comprises an index corresponding to the set of one or more measurement-related signals associated with the set of resource elements.

3. The method of claim 2 , wherein the index is indicated in the configuration information comprised in the RRC message.

4. The method of claim 1 , wherein the set of one or more measurement-related signals comprise a first set of one or more non-zero power channel state information reference signals (CSI-RSs).

5. The method of claim 1 , wherein the set of one or more measurement-related signals comprise a first set of one or more channel state information interference measurement (CSI-IM) signals.

6. The method of claim 1 , wherein the configuration information indicates a plurality of sets of one or more measurement-related signals, each of the plurality of sets of one or more measurement-related signals being associated with a respective set of resource elements and a respective index.

7. The method of claim 1 , wherein the second indication indicates uplink resources for sending the at least one measurement report.

8. The method of claim 7 , wherein the uplink resources correspond to one or more physical uplink control channel or physical uplink shared channel resources.

9. The method of claim 1 , wherein the second indication indicates a type of measurement to be reported.

10. The method of claim 9 , wherein the type of measurement corresponds to a reference signal received power (RSRP) measurement.

15. The WTRU of claim 11 , wherein the set of one or more measurement-related signals comprise a first set of one or more channel state information interference measurement (CSI-IM) signals.

16. The WTRU of claim 11 , wherein the configuration information indicates a plurality of sets of one or more measurement-related signals, each of the plurality of sets of one or more measurement-related signals being associated with a respective set of resource elements and a respective index.

17. The WTRU of claim 11 , wherein the second indication indicates uplink resources for sending the at least one measurement report.

18. The WTRU of claim 17 , wherein the uplink resources correspond to one or more physical uplink control channel or physical uplink shared channel resources.

19. The WTRU of claim 11 , wherein the second indication indicates that a reference signal received power (RSRP) measurement is to be reported.

20. A base station comprising a processor and memory, the processor and memory configured to:

send a radio resource control (RRC) message to a wireless transmit/receive unit (WTRU), the RRC message comprising configuration information indicating a set of one or more measurement-related signals, the set of one or more measurement-related signals being associated with a set of resource elements;

send a first indication, the first indication indicating that the set of one or more measurement-related signals associated with the set of resource elements has been activated;

send a second indication, the second indication indicating a request to the WTRU to report one or more measurements associated with the first set of one or more measurement-related signals associated with the set of resource elements;

receive at least one measurement report based on sending the second indication, the at least one measurement report comprising one or more measurement values associated with the set of one or more measurement-related signals associated with the set of resource elements; and

send a third indication, the third indication indicating that the set of one or more measurement-related signals associated with the set of resource elements has been de-activated.
