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, an activation indication of semi-persistent channel state information (SP-CSI) reporting associated with a cell;
receiving, by the wireless device, an uplink grant indicating scheduled transport block transmission associated with the cell; and
based on scheduled transmission of a SP-CSI report via a first physical uplink shared channel (PUSCH) of the cell overlapping, 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
not transmitting, via the first PUSCH, 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 2 , wherein the timing criterion comprises a time interval indicated by DCI comprising the uplink grant.
4. The method of claim 1 , wherein the one or more selection criteria comprise a periodicity criterion, wherein the not transmitting 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.
5. The method of claim 1 , wherein the one or more selection criteria comprise a size criterion, and wherein the not transmitting the SP-CSI report is based on a size of the transport block.
6. The method of claim 1 , wherein the one or more selection criteria comprise a size criterion, and wherein the not transmitting the SP-CSI report is based on a comparison of:
a size of the SP-CSI report; and
a size of the transport block.
7. The method of claim 1 , wherein the one or more selection criteria comprise a priority criterion, and wherein the not transmitting the SP-CSI report is based on a priority of a logical channel associated with the transport block.
8. The method of claim 1 , further comprising receiving a radio resource control (RRC) message comprising the one or more selection criteria.
9. A method comprising:
receiving, by a wireless device, an activation indication of semi-persistent channel state information (SP-CSI) reporting associated with a carrier;
receiving, by the wireless device, an uplink grant indicating a scheduled physical uplink shared channel (PUSCH) for a transport block associated with the carrier; and
based on a scheduled PUSCH for an SP-CSI report associated with the carrier overlapping, in time, with the scheduled PUSCH for the transport block, and based on one or more selection criteria:
transmitting a first PUSCH comprising the transport block; and
not transmitting a second PUSCH associated with the SP-CSI report.
10. The method of claim 9 , wherein the one or more selection criteria comprise a timing criterion associated with at least one of:
the first PUSCH; or
the second PUSCH.
11. The method of claim 10 , wherein the timing criterion comprises a time interval indicated by DCI comprising the uplink grant.
12. The method of claim 9 , wherein the one or more selection criteria comprise a periodicity criterion, wherein the not transmitting the second PUSCH is based on a comparison of:
a periodicity associated with transport block transmission; and
a periodicity associated with SP-CSI report transmission.
13. The method of claim 9 , wherein the one or more selection criteria comprise a size criterion, and wherein the not transmitting the second PUSCH is based on a size of the transport block.
14. The method of claim 9 , wherein the one or more selection criteria comprise a size criterion, and wherein the not transmitting the second PUSCH is based on a comparison of:
a size of the SP-CSI report; and
a size of the transport block.
15. The method of claim 9 , wherein the one or more selection criteria comprise a priority criterion, and wherein the not transmitting the second PUSCH is based on a priority of a logical channel associated with the transport block.
16. The method of claim 9 , further comprising receiving a radio resource control (RRC) message comprising the one or more selection criteria.
17. A method comprising:
transmitting, by a base station to a wireless device, an activation indication of semi-persistent channel state information (SP-CSI) reporting associated with a cell;
transmitting, to the wireless device, an uplink grant indicating scheduled transport block transmission associated with the cell; and
based on scheduled reception of a SP-CSI report via a first physical uplink shared channel (PUSCH) of the cell overlapping, in time, with scheduled reception of a transport block via a second PUSCH of the cell, and based on one or more selection criteria:
receiving, via the second PUSCH, the transport block; and
not receiving, via the first PUSCH, the SP-CSI report.
18. The method of claim 17 , wherein the one or more selection criteria comprise a timing criterion associated with at least one of:

22. The method of claim 17 , wherein the one or more selection criteria comprise a size criterion, and wherein the not receiving the SP-CSI report is based on a comparison of:
a size of the SP-CSI report; and

25. A method comprising:
transmitting, by a base station to a wireless device, an activation indication of semi-persistent channel state information (SP-CSI) reporting associated with a carrier;
