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.
Claims28
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 group common DCI comprising a cancellation indication for an uplink transmission associated with the uplink radio resource;
- and
- transmitting, based on a value of the first NDI being associated with a value of a second NDI, a first uplink transmission corresponding to a canceled uplink transmission associated with the uplink radio resource.
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 group common DCI comprising a cancellation indication for a first uplink transmission associated with the uplink radio resource;
- and
- transmitting, based on a value of the first NDI being associated with a value of a second NDI, a second uplink transmission different from the first uplink transmission.
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 group common DCI comprising a cancellation indication for an uplink transmission associated with the uplink radio resource;
- and
- transmit, based on a value of the first NDI being associated with a value of a second NDI, a first uplink transmission corresponding to a canceled uplink transmission associated with the uplink radio resource.
