Abstract
A method is provided for acknowledging a semi-persistent scheduling (SPS) uplink resource release. The method comprises receiving an SPS resource release signal over a physical downlink control channel in a Downlink Control Information (DCI) format 1A. The signal includes an indicator that indicates that the signal pertains to at least one of an uplink resource release and a downlink resource release. The method further comprises sending an acknowledgement to confirm the release of the resource.
Claims21
A method for acknowledging a semi-persistent scheduling (SPS) resource release, comprising:
- receiving an SPS resource release signal over a physical downlink control channel in a Downlink Control Information (DCI) format 1A, the signal including an indicator that indicates that the signal pertains to at least one of an uplink resource release and a downlink resource release,
- wherein the indicator is included in a data field in the signal, and
- wherein the data field is at least one of:
- a Localized/Distributed Assignment Flag field;
- and
- a ‘TPC Command for PUCCH’ field.
A user equipment (UE) comprising:
- a processor configured to receive an SPS resource release signal over a physical downlink control channel in a Downlink Control Information (DCI) format 1A, the signal including an indicator that indicates that the signal pertains to at least one of an uplink resource release and a downlink resource release,
- wherein the indicator is included in a data field in the signal, and
- wherein the data field is at least one of:
- a Localized/Distributed Assignment Flag field;
- and
- a ‘TPC Command for PUCCH’ field.
An access device comprising:
- a processor configured to transmit an uplink SPS resource release message over a physical downlink control channel in a Downlink Control Information (DCI) format 1A,
- wherein the message includes an indicator that indicates that the message pertains to an uplink resource release,
- wherein the indicator is included in a data field in the resource release message, and
- wherein the data field is at least one of:
- a Localized/Distributed Assignment Flag field;
- and
- a ‘TPC Command for PUCCH’ field.
