Resolving time-domain resource allocation ambiguity

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• determine that downlink control information is associated with a control resource set (CORESET) that includes a common search space (CSS) candidate and a UE-specific search space (UESS) candidate that are aligned with each other;
• and
• decode downlink control information at least in part in accordance with a rule indicating whether the downlink control information is to be decoded in accordance with the CSS candidate or the UESS candidate,
• wherein the rule indicates that the downlink control information is to be decoded in accordance with the CSS candidate when the downlink control information, when decoded, is not distinguishable as associated with the CSS candidate or the UESS candidate.

An apparatus for wireless communication, comprising:

• means for determining that a first physical downlink control channel (PDCCH) candidate and a second PDCCH candidate in a control resource set (CORESET) are aligned with each other, wherein the first PDCCH candidate is a common search space (CSS) candidate and the second PDCCH candidate is a UE-specific search space (UESS) candidate;
• and
• means for decoding downlink control information at least in part in accordance with a rule indicating whether the downlink control information is to be decoded in accordance with the CSS candidate or the UESS candidate,
• wherein the rule indicates that the downlink control information is to be decoded in accordance with the CSS candidate when the downlink control information, when decoded, is not distinguishable as associated with the CSS candidate or the UESS candidate.

A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
• determine that a first physical downlink control channel (PDCCH) candidate and a second PDCCH candidate in a control resource set (CORESET) are aligned with each other, wherein the first PDCCH candidate is a common search space (CSS) candidate and the second PDCCH candidate is a UE-specific search space (UESS) candidate;
• and
• decode downlink control information at least in part in accordance with a rule indicating whether the downlink control information is to be decoded in accordance with the CSS candidate or the UESS candidate,
• wherein the rule indicates that the downlink control information is to be decoded in accordance with the CSS selected candidate when the downlink control information, when decoded, is not distinguishable as associated with the CSS candidate or the UESS candidate.
