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).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of and claims priority to U.S. patent application Ser. No. 17/729,625 filed on Apr. 26, 2022, which is a continuation of U.S. patent application Ser. No. 16/788,079 filed on Feb. 11, 2020 (now U.S. Pat. No. 11,405,874), which claims the benefit of U.S. Provisional Application No. 62/803,999 filed on Feb. 11, 2019, each of which is hereby incorporated by reference in its entirety. BACKGROUND A base station sends a message to a wireless device to indicate an uplink grant for the wireless device. The wireless device uses the uplink grant to send uplink transmissions to the base station. SUMMARY The following summary presents a simplified summary of certain features. The summary is not an extensive overview and is not intended to identify key or critical elements. Systems, methods, and apparatuses for wireless communications are described. Transmissions from a wireless device may be cancelled/delayed to enable a wireless device to send another transmission (e.g., for more urgent communications, higher priority service, etc.). A base station may send one or more control messages, such as a pre-emption message and/or a power control message, to the wireless device. The wireless device may pre-empt (e.g., based on a pre-emption message) transmission of one or more repetitions (e.g., redundancy versions) of a message (e.g., one or more transport blocks (TB s)) among a plurality of repetitions of the message. The wireless device may determine/assume that a pre-empted message has been transmitted, transmit the pre-empted message in/via another time slot or other time duration, re-arrange an order of non-pre-empted messages, and/or cancel transmissions of the plurality of repetitions of the message. The wireless device may determine not to use one or more power control messages to determine a transmission power of the wireless device, for example, based on receiving a pre-emption message. Pre-empting transmission of one or more repetitions of the message and/or not using the one or more power control messages may result in advantages such as reduced power consumption, reduced transmission latency, more efficient use of scheduled resources in a network, reduced interference between multiple wireless devices, and/or higher network throughput. These and other features and advantages are described in greater detail below.
