The wireless device may receive a first downlink control information (DCI) scheduling an uplink transport block (TB) via uplink resources of the cell, and a second DCI indicating a transmission cancelation on one or more resources of the uplink resources. The wireless device may map the uplink TB to a portion of the uplink resources based on the rate matching in response to a ratio of the one or more resources to the uplink resources being equal to or greater than the ratio threshold, and the puncturing in response to the ratio being less than the ratio threshold. The wireless device may transmit the uplink TB via the portion of the uplink resources in response to the mapping. ## Claims ### Claim 1 A method comprising: receiving, by a wireless device, one or more radio resource control (RRC) messages comprising configuration parameters of a cell, wherein the configuration parameters indicate a ratio threshold for selecting between rate matching and puncturing;
