The condition monitoring configuration (36) configures the wireless device (16) to monitor a condition. The wireless device (16) is to apply the conditional mobility configuration (38) when the wireless device (16) detects fulfillment of the condition. The wireless device (16) is configured to process the condition monitoring configuration (36) upon receiving the message (34), and to process the conditional mobility configuration (38) subject to a processing precondition being met. ## Claims ### Claim 1 A method performed by a wireless device, the method comprising: receiving, from a radio network node, a message that includes: a condition monitoring configuration which configures the wireless device to monitor a condition; and a conditional mobility configuration which the wireless device is to apply when the wireless device detects fulfillment of the condition; processing the condition monitoring configuration upon receiving the message; receiving an uplink grant from the radio network node; transmitting, to the radio network node and based on the uplink grant, a response to the message; and processing the conditional mobility configuration subject to a processing precondition being met, wherein the processing precondition is met after, but not responsive to, transmitting the response. ### Claim 2 (depends on 1) The method of claim 1, wherein the wireless device is configured to process the message within a maximum allowed delay, and wherein processing of the conditional mobility configuration is subjected to the processing precondition being met in order for the wireless device to comply with the maximum allowed delay for processing the message. ### Claim 3 (depends on 2) The method of claim 2, wherein the maximum allowed delay is independent of a number of conditional mobility configurations included in the message. ### Claim 4 (depends on 1) The method of claim 1, wherein said processing the conditional mobility configuration comprises processing the conditional mobility configuration only if and when the processing precondition is met. ### Claim 5 (depends on 1) The method of claim 1, wherein the processing precondition is met when the condition is fulfilled or when a mobility procedure associated with the conditional mobility configuration is triggered or executed. ### Claim 6 (depends on 1) The method of claim 1, wherein the processing precondition is met: when a time-to-trigger associated with the conditional mobility configuration starts; or when the wireless device monitors, or begins to monitor, for fulfillment of the condition. ### Claim 7 (depends on 1) The method of claim 1, wherein processing the conditional mobility configuration includes determining whether the wireless device is able to comply with the conditional mobility configuration. ### Claim 8 (depends on 1) The method of claim 1, wherein the message includes multiple conditional mobility configurations, and wherein the method comprises processing each of the conditional mobility configurations only if and when a respective processing precondition for that conditional mobility configuration is met. ### Claim 9 A wireless device comprising: communication circuitry; and processing circuitry configured to: receive, from a radio network node, a message that includes: a condition monitoring configuration which configures the wireless device to monitor a condition; and a conditional mobility configuration which the wireless device is to apply when the wireless device detects fulfillment of the condition; process the condition monitoring configuration upon receiving the message; receive an uplink grant from the radio network node; transmit, to the radio network node and based on the uplink grant, a response to the message; and process the conditional mobility configuration subject to a processing precondition being met, wherein the processing precondition is met after, but not responsive to, transmitting the response. ### Claim 10 (depends on 9) The wireless device of claim 9, wherein the processing circuitry is configured to process the message within a maximum allowed delay, and to subject processing of the conditional mobility configuration to the processing precondition being met in order for the wireless device to comply with the maximum allowed delay for processing the message. ### Claim 11 (depends on 10) The wireless device of claim 10, wherein the maximum allowed delay is independent of a number of conditional mobility configurations included in the message. ### Claim 12 (depends on 9) The wireless device of claim 9, wherein the processing circuitry is configured to process the conditional mobility configuration only if and when the processing precondition is met. ### Claim 13 (depends on 9) The wireless device of claim 9, wherein the processing precondition is met when the condition is fulfilled or when a mobility procedure associated with the conditional mobility configuration is triggered or executed. ### Claim 14 (depends on 9) The wireless device of claim 9, wherein the processing precondition is met: when a time-to-trigger associated with the conditional mobility configuration starts; when the wireless device monitors, or begins to monitor, for fulfillment of the condition. ### Claim 15 (depends on 9) The wireless device of claim 9, wherein the processing circuitry is configured to determine whether the wireless device is able to comply with the conditional mobility configuration. ### Claim 16 (depends on 9) The wireless device of claim 9, wherein the message includes multiple conditional mobility configurations, and wherein the processing circuitry is configured to process each of the conditional mobility configurations only if and when a respective processing precondition for that conditional mobility configuration is met. ### Claim 17 A non-transitory computer-readable storage medium on which is stored instructions that, when executed by a processor of a wireless device, causes the wireless device to: receive, from a radio network node, a message that includes: a condition monitoring configuration which configures the wireless device to monitor a condition; and a conditional mobility configuration which the wireless device is to apply when the wireless device detects fulfillment of the condition; process the condition monitoring configuration upon receiving the message; receive an uplink grant from the radio network node; transmit, to the radio network node and based on the uplink grant, a response to the message; and process the conditional mobility configuration subject to a processing precondition being met, wherein the processing precondition is met after, but not responsive to, transmitting the response. ### Claim 18 (depends on 1) The method of claim 1, wherein the response: acknowledges the message; indicates whether the wireless device is able to comply with all or some of the conditional mobility configurations; and/or indicates whether the wireless device succeeded or failed in complying with or applying all or some of the conditional mobility configurations. ### Claim 19 (depends on 9) The wireless device of claim 9, wherein the response: acknowledges the message; indicates whether the wireless device is able to comply with all or some of the conditional mobility configurations; and/or indicates whether the wireless device succeeded or failed in complying with or applying all or some of the conditional mobility configurations.
