Abstract: a wireless device performs an uplink transmission, such as an idle-mode uplink transmission using preconfigured uplink resources (pur). the wireless device determines whether a serving-cell signal measurement m was completed within a predetermined range of time before a reference time t, the reference time t corresponding to an uplink transmission opportunity. responsive to determining that the serving-cell signal measurement m was not completed within the predetermined range of time, the wireless device either defers transmission to a subsequent transmission opportunity, or drops the uplink transmission, or collects an additional serving-cell measurement m′ that falls within the predetermined range of time, for use in validating a ta for transmitting at the transmission uplink opportunity and/or for estimating a pl for power control of a transmission at the uplink transmission opportunity.
