Abstract
A base station may cancel or delay (e.g., pre-empt) a transmission from a wireless device by sending a pre-emption indication to the wireless device. Based on receiving the pre-emption indication, the wireless device may cancel the transmission, store an indication associated with the cancelled transmission, and/or store the cancelled transmission in a data buffer. The base station may request transmission of the data unit (e.g., at a later time) by transmitting another indication.
Claims32
A method comprising:
- receiving, by a wireless device, first downlink control information (DCI) that indicates:
- an uplink radio resource;
- and
- a first new data indicator (NDI);
- receiving second DCI that indicates that the uplink radio resource is pre-empted;
- based on detecting that the uplink radio resource is pre-empted, cancelling an uplink transmission associated with the uplink radio resource;
- and
- based on the cancelling the uplink transmission and based on a comparison of the first NDI to a second NDI received via third DCI, transmitting one of:
- a first media access control (MAC) packet corresponding to the uplink transmission, or
- a second MAC packet.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive first downlink control information (DCI) that indicates:
- an uplink radio resource;
- and
- a first new data indicator (NDI);
- receive second DCI that indicates that the uplink radio resource is pre-empted;
- based on detecting that the uplink radio resource is pre-empted, cancel an uplink transmission associated with the uplink radio resource;
- and
- based on cancelling the uplink transmission and based on a comparison of the first NDI to a second NDI received via third DCI, transmit one of:
- a first media access control (MAC) packet corresponding to the uplink transmission, or
- a second MAC packet.
A non-transitory computer-readable medium storing instructions that, when executed, cause a wireless device to:
- receive first downlink control information (DCI) that indicates:
- an uplink radio resource;
- and
- a first new data indicator (NDI);
- receive second DCI that indicates that the uplink radio resource is pre-empted;
- based on detecting that the uplink radio resource is pre-empted, cancel an uplink transmission associated with the uplink radio resource;
- and
- based on cancelling the uplink transmission and based on a comparison of the first NDI to a second NDI received via third DCI, transmit one of:
- a first media access control (MAC) packet corresponding to the uplink transmission, or
- a second MAC packet.
A system comprising:
- a wireless device;
- and
- a base station,
- wherein the wireless device comprises:
- one or more first processors;
- and
- first memory storing first instructions that, when executed by the one or more first processors, cause the wireless device to:
- receive first downlink control information (DCI) that indicates:
- an uplink radio resource;
- and
- a first new data indicator (NDI);
- receive second DCI that indicates that the uplink radio resource is pre-empted;
- based on detecting that the uplink radio resource is pre-empted, cancel an uplink transmission associated with the uplink radio resource;
- and
- based on cancelling the uplink transmission and based on a comparison of the first NDI to a second NDI received via third DCI, transmit one of:
- a first media access control (MAC) packet corresponding to the uplink transmission, or
- a second MAC packet, and
- wherein the base station comprises:
- one or more second processors;
- and
- second memory storing second instructions that, when executed by the one or more second processors, cause the base station to:
- send the first DCI.
