Abstract
Wireless communications are described for controlling a transmission. A base station may cancel, delay, and/or request a retransmission of a message. The base station may send a control message to control a transmission in a communication network. A wireless device may cancel a transmission (e.g., based on a pre-emption indication), determine a transmission power for a transmission (e.g., based on a power control message), and/or determine a retransmission of a message (e.g., based on a repetition indication).
Claims20
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 a radio resource control (RRC) message comprising configuration parameters indicating:
- a number of repetitions of a transport block (TB) associated with a configured grant for transmissions of the TB via a number of consecutive slots comprising a first slot and a second slot;
- and
- a redundancy version (RV) sequence for the number of repetitions of the TB;
- determine, based on the RV sequence:
- a first RV value associated with a first transmission of the TB in the first slot;
- and
- a second RV value associated with a second transmission of the TB in the second slot;
- receive a downlink control information (DCI) comprising a cancelation indication indicating that an uplink radio resource is pre-empted;
- in response to receiving the DCI and the uplink radio resource overlapping with the first slot, drop the first transmission of the TB with the first RV value;
- and
- transmit the TB with the second RV value, wherein the uplink radio resource does not overlap with the second slot.

- and
- a second RV value associated with a second transmission of the TB in the second slot;
- receive a downlink control information (DCI) comprising a cancelation indication;
- drop, based on the cancelation indication and in the first slot, the first transmission of the TB with the first RV value;
- and
- transmit, in the second slot, the TB with the second RV value.
