Abstract
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an MT. The MT determines whether a first parameter is received from a base station via radio resource control (RRC) signaling. The first parameter comprises a bitmap. The bitmap indicates one or more processes, of a group of hybrid automatic repeat request (HARQ) processes, that are to be in a feedback state of disabled or enabled. When the first parameter is received, the MT disables or enables feedback of the one or more processes according to the bitmap.
Claims18
A method of wireless communication of a mobile termination (MT), comprising:
- determining whether a first parameter is received from a base station via radio resource control (RRC) signaling, the first parameter comprising a bitmap indicating one or more processes, of a group of hybrid automatic repeat request (HARQ) processes, that are to be in a feedback state of disabled or enabled feedback;
- when the first parameter is received, disabling or enabling feedback of the one or more processes according to the bitmap;
- receiving, from the base station, downlink control information (DCI) scheduling a downlink transmission, the DCI including a DCI parameter in a re-interpreted DCI field, wherein the DCI parameter indicates to disable or enable feedback of a first HARQ process for the downlink transmission;
- and
- when the first parameter is received, maintaining or reversing a feedback state of the first HARQ process, configured by the bitmap, based on the DCI parameter, wherein a first state of the re-interpreted DCI field indicates disabling feedback and states other than the first state indicate enabling feedback.
A method of wireless communication of a mobile termination (MT), comprising:
- determining whether a first parameter is received from a base station via radio resource control (RRC) signaling, the first parameter comprising a bitmap indicating one or more processes, of a group of hybrid automatic repeat request (HARQ) processes, that are to be in a feedback state of disabled or enabled feedback;
- when the first parameter is received, disabling or enabling feedback of the one or more processes according to the bitmap;
- and
- receiving, from the base station, downlink control information (DCI) scheduling a downlink transmission, the DCI including a DCI parameter that indicates to disable or enable feedback of a first HARQ process for the downlink transmission;
- wherein the DCI parameter is in a re-interpreted DCI field with another parameter;
- wherein the re-interpreted DCI field is “HARQ-ACK resource” field for Narrowband Internet of Things (NB-IoT) communications and is “HARQ-ACK resource offset” field for enhanced Machine Type Communications coverage enhancement mode B (eMTC CEModeB communications;
- wherein a first value in the “HARQ-ACK resource offset” indicates disabling feedback of the first HARQ process and other values in the “HARQ-ACK resource offset” field indicate enabling feedback of the first HARQ process.
A method of wireless communication of a mobile termination (MT), comprising:
- determining whether a first parameter is received from a base station via radio resource control (RRC) signaling, the first parameter comprising a bitmap indicating one or more processes, of a group of hybrid automatic repeat request (HARQ) processes, that are to be in a feedback state of disabled or enabled feedback;
- when the first parameter is received, disabling or enabling feedback of the one or more processes according to the bitmap;
- and
- receiving, from the base station, downlink control information (DCI) scheduling a downlink transmission, the DCI including a DCI parameter that indicates to disable or enable feedback of a first HARQ process for the downlink transmission;
- wherein the DCI parameter is in a re-interpreted DCI field with another parameter;
- wherein the re-interpreted DCI field is “HARQ-ACK resource” field for Narrowband Internet of Things (NB-IoT) communications and is “HARQ-ACK resource offset” field for enhanced Machine Type Communications coverage enhancement mode B (eMTC CEModeB communications;
- wherein a first value in the “HARQ-ACK resource” indicates disabling feedback of the first HARQ process and other values in the “HARQ-ACK resource” field indicate enabling feedback of the first HARQ process.
An apparatus for wireless communication, the apparatus being a mobile termination (MT), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- determine whether a first parameter is received from a base station via radio resource control (RRC) signaling, the first parameter comprising a bitmap indicating one or more processes, of a group of hybrid automatic repeat request (HARQ) processes, that are to be in a feedback state of disabled or enabled;
- when the first parameter is received, disable or enable feedback of the one or more processes according to the bitmap;
- receive, from the base station, downlink control information (DCI) scheduling a downlink transmission, the DCI including a DCI parameter in a re-interpreted DCI field, wherein the DCI parameter indicates to disable or enable feedback of a first HARQ process for the downlink transmission;
- and
- when the first parameter is received, maintain or reverse a feedback state of the first HARQ process, configured by the bitmap, based on the DCI parameter, wherein a first state of the re-interpreted DCI field indicates disabling feedback and states other than the first state indicate enabling feedback.
A non-transitory computer-readable medium storing computer executable code for wireless communication of a user equipment (UE), comprising code to:
- determine whether a first parameter is received from a base station via radio resource control (RRC) signaling, the first parameter comprising a bitmap indicating one or more processes, of a group of hybrid automatic repeat request (HARQ) processes, that are to be in a feedback state of disabled or enabled;
- when the first parameter is received, disable or enable feedback of the one or more processes according to the bitmap;
- receive, from the base station, downlink control information (DCI) scheduling a downlink transmission, the DCI including a DCI parameter in a re-interpreted DCI field, wherein the DCI parameter indicates to disable or enable feedback of a first HARQ process for the downlink transmission;
- and
- when the first parameter is received, maintain or reverse a feedback state of the first HARQ process, configured by the bitmap, based on the DCI parameter, wherein a first state of the re-interpreted DCI field indicates disabling feedback and states other than the first state indicate enabling feedback.
