Abstract

A wireless transmit/receive unit (WTRU) may receive a first higher layer configuration for a cancellation indication (CI). Further, the first higher layer configuration may include a set of reference frequency resources. Also, the WTRU may receive a grant indicating a frequency allocation and a time allocation for a scheduled transmission. Further, on a condition that the CI is received, the WTRU may interrupt the scheduled transmission. Additionally, the CI may indicate a subset of frequency resources of the set of reference frequency resources for each of a set of time symbols. Also, the WTRU may cancel the scheduled transmission on a condition that the subset of frequency resources of a set of time symbols overlaps with the frequency allocation and the time allocation for the scheduled transmission. In a further example, the first higher layer configuration may include an applicable maximum priority and the grant may include a priority index.

Claims20

Dependent claims

A wireless transmit/receive unit (WTRU) comprising a processor configured to:

receive, via radio resource control (RRC) signaling, an indication of a set of reference frequency resources for which uplink cancellation could occur, an indication of at least one priority for which uplink cancellation is applicable, and an allocation for a configured grant, the allocation for the configured grant comprising a frequency allocation for the configured grant, a time allocation for the configured grant, and a priority index for the configured grant;
receive a physical downlink control channel (PDCCH) transmission, the PDCCH comprising downlink control information (DCI), the DCI comprising cancellation indication (CI) information, wherein the CI information indicates that a subset of the set of reference frequency resources are subject to uplink cancellation in one or more time symbols;
and
cancel at least part of an uplink transmission associated with the configured grant based on the CI information, the frequency allocation for the configured grant, the time allocation for the configured grant, the priority index for the configured grant, and the indication of the at least one priority for which uplink cancellation is applicable received in the RRC signaling.

A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:

receiving, via radio resource control (RRC) signaling, an indication of a set of reference frequency resources for which uplink cancellation could occur, an indication of at least one priority for which uplink cancellation is applicable, and an allocation for a configured grant, the allocation for the configured grant comprising a frequency allocation for the configured grant, a time allocation for the configured grant, and a priority index for the configured grant;
receiving a physical downlink control channel (PDCCH) transmission, the PDCCH comprising downlink control information (DCI), the DCI comprising cancellation indication (CI) information, wherein the CI information indicates that a subset of the set of reference frequency resources are subject to uplink cancellation in one or more time symbols;
and
cancelling at least part of an uplink transmission associated with the configured grant based on the Cl information, the frequency allocation for the configured grant, the time allocation for the configured grant, the priority index for the configured grant, and the indication of the at least one priority for which uplink cancellation is applicable received in the RRC signaling.
