Abstract

Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

Claims (34)

1. A method, comprising:

identifying, by a wireless communication device, a search space set including a plurality of physical downlink control channel (PDCCH) candidate search spaces for a downlink control channel, wherein the search space set is within a control resource set (CORESET);

determining, by the wireless communication device, that a preconfigured downlink resource overlaps with the CORESET in a transmission slot; and

monitoring, by the wireless communication device, for a downlink control message over the downlink control channel by excluding monitoring for the downlink control message in the entire CORESET within the transmission slot in response to determining that the preconfigured downlink resource overlaps with the CORESET.

2. The method of claim 1 , further comprising:

determining, by the wireless communication device, that resources of a second PDCCH candidate search space of the plurality of PDCCH candidate search spaces does not overlap with any preconfigured resources,

wherein the monitoring includes monitoring, by the wireless communication device, the downlink control message from the second PDCCH candidate search space.

3. The method of claim 1 , further comprising:

receiving, by the wireless communication device, a configuration indicating the preconfigured resource allocated for a transmission of at least one of a synchronization signal block (SSB).

4. The method of claim 1 , further comprising:

receiving, by the wireless communication device, a configuration indicating the preconfigured resource allocated for a transmission of at least one of a synchronization signal, a broadcast communication signal, a reference signal, or a downlink data channel signal.

5. An apparatus comprising:

a processor configured to:

identify a search space set including a plurality of physical downlink control channel (PDCCH) candidate search spaces for a downlink control channel, wherein the search space set is within a control resource set (CORESET);

determine that a preconfigured downlink resource overlaps with the CORESET in a transmission slot; and

monitor for a downlink control message over the downlink control channel by excluding monitoring for the downlink control message in the entire CORESET within the transmission slot in response to determining that the preconfigured downlink resource overlaps with the CORESET.

6. The apparatus of claim 5 , wherein the processor is further configured to:

determine that resources of a second PDCCH candidate search space of the plurality of PDCCH candidate search spaces does not overlap with any preconfigured resources; and

monitor for the downlink control message from the second PDCCH candidate search space.

7. The apparatus of claim 5 , further comprising:

a transceiver configured to receive a configuration indicating the preconfigured resource allocated for a transmission of a synchronization signal block (SSB).

8. The apparatus of claim 5 , further comprising:

a transceiver configured to receive a configuration indicating the preconfigured resource allocated for a transmission of at least one of a synchronization signal, a broadcast communication signal, a reference signal, or a downlink data channel signal.

9. An apparatus comprising:

means for identifying a search space set including a plurality of physical downlink control channel (PDCCH) candidate search spaces for a downlink control channel, wherein the search space set is within a control resource set (CORESET);

means for determining that a preconfigured downlink resource overlaps with the CORESET in a transmission slot; and

means for monitoring for a downlink control message over the downlink control channel by excluding monitoring for the downlink control message in the entire CORESET within the transmission slot in response to determining that the preconfigured downlink resource overlaps with the CORESET.

10. The apparatus of claim 9 , further comprising:

means for determining that resources of a second PDCCH candidate search space of the plurality of PDCCH candidate search spaces does not overlap with any preconfigured resources,

wherein the means for monitoring for the downlink control message is further configured to monitor the downlink control message from the second PDCCH candidate search space.

11. The apparatus of claim 9 , further comprising:

means for receiving a configuration indicating the preconfigured resource allocated for a transmission of at a synchronization signal block (SSB).

12. The apparatus of claim 9 , further comprising:

means for receiving a configuration indicating the preconfigured resource allocated for a transmission of at least one of a synchronization signal, a broadcast communication signal, a reference signal, or a downlink data channel signal.
