Selection of grant and CSI
Uplink resources for semi-persistent channel state information (SP-CSI) reports and other uplink transport block transmissions may be managed. If resources allocated to the SP-CSI reports overlap, in time, with resources allocated to the uplink transport block transmissions, a determination of whether to drop an SP-CSI report may be made. Various selection criteria may be used to make this determination.
1. A method comprising:
receiving, by a wireless device, first downlink control information (DCI) indicating activation of semi-persistent channel state information (SP-CSI) reporting associated with a cell;
receiving, by the wireless device, second DCI comprising an uplink grant indicating scheduled transport block transmission associated with the cell; and
based on a determination that scheduled transmission of a SP-CSI report via a first physical uplink shared channel (PUSCH) of the cell overlaps, in time, with scheduled transmission of a transport block via a second PUSCH of the cell, and based on one or more selection criteria:
transmitting, via the second PUSCH, the transport block; and
dropping the scheduled transmission of the SP-CSI report.
2. The method of claim 1 , wherein the one or more selection criteria comprise a timing criterion associated with at least one of:
the first PUSCH; or
the second PUSCH.
3. The method of claim 1 , wherein the one or more selection criteria comprise a periodicity criterion, wherein the dropping the scheduled transmission of the SP-CSI report is based on a comparison of:
a periodicity associated with transport block transmission; and
a periodicity associated with SP-CSI report transmission.
4. The method of claim 1 , wherein the one or more selection criteria comprise a size criterion, and wherein the dropping the scheduled transmission of the SP-CSI report is based on a size of the transport block.
5. The method of claim 1 , wherein the one or more selection criteria comprise a size criterion, and wherein the dropping the scheduled transmission of the SP-CSI report is based on a comparison of:
a size of the SP-CSI report; and
a size of the transport block.
6. The method of claim 1 , wherein the one or more selection criteria comprise a priority criterion, and wherein the dropping the scheduled transmission of the SP-CSI report is based on a priority of a logical channel associated with the transport block.
7. The method of claim 1 , further comprising receiving a radio resource control (RRC) message comprising the one or more selection criteria.
8. A method comprising:
determining, by a wireless device, that scheduled transmission of one or more semi-persistent channel state information (SP-CSI) reports, associated with the wireless device, overlap in time with scheduled transmission of one or more transport blocks; and
based on the determining, and based on one or more selection criteria:
transmitting, via one or more uplink channel resources, the one or more transport blocks; and
dropping the scheduled transmission of the one or more SP-CSI reports.
9. The method of claim 8 , wherein the one or more selection criteria comprise a timing criterion associated with at least one of:
the scheduled transmission of the one or more SP-CSI reports; or
the scheduled transmission of the one or more transport blocks.
10. The method of claim 8 , wherein the one or more selection criteria comprise a periodicity criterion, wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a comparison of:
a periodicity associated with transport block transmission; and
a periodicity associated with SP-CSI report transmission.
11. The method of claim 8 , wherein the one or more selection criteria comprise a size criterion, and wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a size of the one or more transport blocks.
12. The method of claim 8 , wherein the one or more selection criteria comprise a size criterion, and wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a comparison of:
a size of the one or more SP-CSI reports; and
a size of the one or more transport blocks.
13. The method of claim 8 , wherein the one or more selection criteria comprise a priority criterion, and wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a priority of a logical channel associated with the one or more transport blocks.
14. The method of claim 8 , further comprising receiving a radio resource control (RRC) message comprising the one or more selection criteria.
15. A method comprising:
receiving, by a wireless device, configuration parameters of semi-persistent channel state information (SP-CSI) reporting associated with a cell;
transmitting, via a plurality of SP-CSI resources, a plurality of SP-CSI reports;
receiving information indicating a grant of transmission of one or more transport blocks; and
dropping scheduled transmission of one or more SP-CSI reports based on:
a determination that scheduled transmission of the one or more transport blocks via a first uplink channel overlaps, in time, with the scheduled transmission of the one or more SP-CSI reports via a second uplink channel; and
one or more timing criteria associated with at least one of:
the first uplink channel; or
the second uplink channel.
16. The method of claim 15 , wherein the one or more timing criteria comprise a periodicity associated with SP-CSI transmission.
17. The method of claim 15 , wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a comparison of:
a periodicity associated with transport block transmission; and
a periodicity associated with SP-CSI report transmission.
18. The method of claim 15 , wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a size of the one or more transport blocks.
19. The method of claim 15 , wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a comparison of:
a size of the one or more SP-CSI reports; and
a size of the one or more transport blocks.
20. The method of claim 15 , wherein the dropping the scheduled transmission of the one or more SP-CSI reports is based on a priority of a logical channel associated with the one or more transport blocks.
21. The method of claim 15 , wherein the one or more timing criteria comprises a transmission time interval (TTI) indicated by the information.
22. The method of claim 2 , wherein the timing criterion comprises a transmission time interval (TTI) indicated by the second DCI.
23. The method of claim 9 , wherein the timing criterion comprises a transmission time interval (TTI) indicated by downlink control information (DCI).
