Receiving control information in NR-U
A WTRU may receive a plurality of monitoring configurations. The plurality of monitoring configurations may be associated with a plurality of sub-bands. The WTRU may apply a monitoring configuration based on the location of a slot inside or outside of a COT. For example, the WTRU may apply (e.g., use) a first monitoring configuration outside a COT. The WTRU may apply a second monitoring configuration in a first slot of a COT. The WTRU may apply a third monitoring configuration to the slots of a COT subsequent to the first slot of the COT. The WTRU may switch back to the first monitoring configuration on a condition that the COT ends.
1. A wireless transmit/receive unit (WTRU) comprising:
a processor configured to:
determine a plurality of sub-bands for a cell;
monitor, in accordance with a first monitoring configuration, a first search space in a first sub-band subset associated with the plurality of sub-bands, wherein the first monitoring configuration comprises an indication of the sub-bands belonging to the first sub-band subset;
receive downlink control information (DCI) that indicates a channel occupancy time (COT) and a second sub-band subset associated with the plurality of sub-bands, wherein the indicated COT indicates a COT duration;
monitor the first search space in the indicated second sub-band subset for a remaining duration of the COT; and
switch from monitoring the first search space in the second sub-band subset to monitoring the first search space in the first sub-band subset based on an end of the COT.
2. The WTRU of claim 1 , wherein the processor is further configured to receive a plurality of monitoring configurations associated with the plurality of sub-bands.
3. The WTRU of claim 1 , wherein the DCI COT indication indicates when to switch from monitoring the first search space in the indicated second sub-band to monitoring the first search space in the first sub-band subset.
4. The WTRU of claim 1 , wherein the processor is further configured to monitor, according to the first monitoring configuration for a physical downlink control channel PDCCH) candidate.
5. The WTRU of claim 1 , wherein the first sub-band subset comprises each of the sub-bands in the plurality of sub-bands, and wherein the second sub-band subset comprises a portion of the sub-bands in the plurality of sub-bands.
6. A method comprising:
determining a plurality of sub-bands for a cell;
monitoring, in accordance with a first monitoring configuration, a first search space in a first sub-band subset associated with the plurality of sub-bands, wherein the first monitoring configuration comprises an indication of the sub-bands belonging to the first sub-band subset;
receiving downlink control information (DCI) that indicates a channel occupancy time (COT) and a second sub-band subset associated with the plurality of sub-bands, wherein the indicated COT indicates a COT duration;
monitoring the first search space in the indicated second sub-band subset for a remaining duration of the COT; and
switching from monitoring the first search space in the second sub-band subset to monitoring the first search space in the first sub-band subset based on an end of the COT.
7. The method of claim 6 , further comprising receiving a plurality of monitoring configurations associated with the plurality of sub-bands.
8. The method of claim 6 , wherein the DCI indicates when to switch from monitoring the first search space in the indicated second sub-band to monitoring the first search space in the first sub-band subset.
9. The method of claim 6 , further comprising monitoring, according to the first monitoring configuration for a physical downlink control channel (PDCCH) candidate.
10. The method of claim 6 , wherein the first sub-band subset comprises each of the sub-bands in the plurality of sub-bands, and wherein the second sub-band subset comprises a portion of the sub-bands in the plurality of sub-bands.
11. A wireless transmit/receive unit (WTRU) comprising:
a processor configured to:
determine a plurality of sub-bands for a cell;
monitor, in accordance with a first monitoring configuration, a first search space in a first sub-band subset associated with the plurality of sub-bands wherein the first monitoring configuration comprises an indication of the sub-bands belonging to the first sub-band subset;
receive downlink control information (DCI) that indicates a channel occupancy time (COT) and a second sub-band subset associated with the plurality of sub-bands, wherein the indicated COT indicates a COT duration; and
