Abstract

Apparatuses, methods, and systems are disclosed for CSI report configuration. One method includes receiving at least one CSI reporting setting. The at least one CSI reporting setting includes at least one CSI RS resource setting, and the CSI reporting setting includes an indication of CSI feedback reporting for multiple transmission points in a mobile communication network. The method includes identifying a set of transmission hypotheses based on the CSI reporting setting. The hypotheses include a combination of single-point transmission from at least one TRP, or multi-point joint transmission from two TRPs. The method includes receiving at least one CSI reference signal resource transmitted from the mobile communication network based on the CSI reference signal resource setting. The method includes generating a set of at least one CSI report based on the CSI reporting setting.

Claims (43)

1 .- 15 . (canceled)

16 . A method of a user equipment (UE), the method comprising:

receiving a channel state information (CSI) reporting setting, wherein the CSI reporting setting comprises a CSI reference signal (RS) resource setting, wherein the CSI reporting setting includes an indication of CSI reporting for multiple transmission-and-reception points (TRPs), wherein the CSI reporting setting corresponds to a set of hypotheses, and wherein each hypothesis of the set of hypotheses corresponds to a single-point transmission from at least one TRP, or a joint multi-point transmission from two TRPs, or a combination thereof;

receiving at least one CSI reference signal (CSI-RS) on a CSI-RS resource based on the CSI-RS resource setting;

generating a CSI report based on the CSI reporting setting and the CSI-RS, wherein the CSI report comprises at least one value of a precoder matrix indicator (“PMI”), a rank indicator (“RI”), a CSI-RS resource indicator (“CRI”), a layer indicator (“LI”), or a channel quality indicator (“CQI”), or a combination thereof, and wherein the at least one value is associated with a hypothesis of the set of hypotheses; and

transmitting the CSI report.

17 . The method of claim 16 , wherein the indication of the CSI reporting for the multiple TRPs comprises a parameter indicating:

a multi-TRP CSI reporting;

at least two CSI-RS identifiers associated with at least two CSI-RS resources;

at least two CSI-RS port groups per CSI-RS resource;

a number of CSI reports;

a number of codebook configurations;

a pair of report quantities; or

a transmission configuration indicator (“TCI”) codepoint in a downlink control information, wherein the TCI codepoint corresponds to at least two TCI states;

or a combination thereof.

18 . The method of claim 16 , wherein the CSI report comprises four or less PMI values, and wherein the CSI report comprise three or less RI values.

19 . The method of claim 18 , wherein:

a first PMI value and a first RI value correspond to a first hypothesis of the set of hypotheses, the set of hypotheses comprising at least two single-TRP transmission hypotheses;

a second PMI value and a second RI value correspond to a second hypothesis of the two single-TRP transmission hypotheses; and

a third PMI value, a fourth PMI value, and a third RI value correspond to a third hypothesis of the set of hypotheses, the set of hypotheses comprising a joint transmission hypothesis from at least two TRPs.

20 . The method of claim 19 , wherein the third RI value corresponds to a number of layers corresponding to both of the at least two TRPs, and wherein the number of layers corresponding to both of the at least two TRPs is based at least in part on a rule.

21 . The method of claim 16 , further comprising:

generating three CSI reports,

wherein a first CSI report of the three CSI reports corresponds to a first hypothesis of the set of hypotheses, wherein the set of hypotheses comprises two single-TRP transmission hypotheses,

wherein a second CSI report of the three CSI reports corresponds to a second hypothesis of the two single-TRP transmission hypotheses, and

wherein a third CSI report of the three CSI reports corresponds to third hypothesis of the set of hypotheses, wherein the set of hypotheses comprises a joint transmission hypothesis from at least two TRPs.

22 . The method of claim 21 , wherein each of the first CSI report and the second CSI report comprise one PMI value, one RI value, and one CQI value.

23 . The method of claim 21 , wherein the third CSI report comprises two PMI values, one RI value, and one CQI value.

24 . The method of claim 21 , wherein the third CSI report comprises two PMI values, two RI values, and one CQI value.

25 . The method of claim 24 , wherein a first RI value of the two RI values corresponds to a first number of layers of a first PMI value of the two PMI values, and wherein a second RI value of the two RI values corresponds to a second number of layers of a second PMI value of the two PMI values.

26 . The method of claim 16 , wherein a first subset of the at least one value of the PMI, the RI, the CRI, the LI, or the CQI, or a combination thereof corresponding to a single-TRP hypothesis is associated with a higher priority related to an order of reporting compared with a second subset of the at least one value of the PMI, the RI, the CRI, the LI, or the CQI, or a combination thereof corresponding to a joint transmission hypothesis from at least two TRPs.

27 . The method of claim 16 , wherein the at least one value of the PMI, the RI, the CRI, the LI, or the CQI, or a combination thereof corresponding to a hypothesis are reported according to a descending order from the CQI value corresponding to the hypothesis.

28 . The method of claim 16 , wherein an order, in which the at least one value of the PMI, the RI, the CRI, the LI, or the CQI, or a combination thereof is reported in the CSI report, is multiplexed by a value of a parameter reported within the CSI report, and the parameter reported corresponds to at least one transmission hypothesis.

29 . A method of a network device, the method comprising:

transmitting a channel state information (CSI) reporting setting, wherein the CSI reporting setting comprises a CSI reference signal (RS) resource setting, wherein the CSI reporting setting includes an indication of CSI reporting for multiple transmission-and-reception points (TRPs), wherein the CSI reporting setting corresponds to a set of hypotheses, and wherein each hypothesis of the set of hypotheses corresponds to a single-point transmission from at least one TRP, or a joint multi-point transmission from two TRPs, or a combination thereof;

transmitting at least one CSI reference signal (CSI-RS) on a CSI-RS resource based on the CSI-RS resource setting, wherein a CSI report is generated based on the CSI reporting setting and the CSI-RS, wherein the CSI report comprises at least one value of a precoder matrix indicator (“PMI”), a rank indicator (“RI”), a CSI-RS resource indicator (“CRT”), a layer indicator (“LI”), or a channel quality indicator (“CQI”), or a combination thereof, and wherein the at least one value is associated with a hypothesis of the set of hypotheses; and

receiving the CSI report.

30 . An apparatus for wireless communication, the apparatus comprising:

a processor; and

a memory coupled to the processor, the memory comprising instructions executable by the processor to cause the apparatus to:

transmit a channel state information (CSI) reporting setting, wherein the CSI reporting setting comprises a CSI reference signal (RS) resource setting, wherein the CSI reporting setting includes an indication of CSI reporting for multiple transmission-and-reception points (TRPs), wherein the CSI reporting setting corresponds to a set of hypotheses, and wherein each hypothesis of the set of hypotheses corresponds to a single-point transmission from at least one TRP, or a joint multi-point transmission from two TRPs, or a combination thereof;

transmit at least one CSI reference signal (CSI-RS) on a CSI-RS resource based on the CSI-RS resource setting, wherein a CSI report is generated based on the CSI reporting setting and the CSI-RS, wherein the CSI report comprises at least one value of a precoder matrix indicator (“PMI”), a rank indicator (“RI”), a CSI-RS resource indicator (“CRT”), a layer indicator (“LI”), or a channel quality indicator (“CQI”), or a combination thereof, and wherein the at least one value is associated with a hypothesis of the set of hypotheses; and
