Abstract
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.
Claims23
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.
4 more elements
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.
3 more elements
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.
