A method, in a network node, of performing cell change of a wireless device from a first cell on a first frequency to a second cell on a second frequency, the method comprising: determining an uplink transmission configuration related to uplink physical channels that can be transmitted by the wireless device on the second cell on the second frequency; comparing a parameter of the determined uplink transmission configuration with a corresponding parameter of a determined uplink transmission configuration related to uplink physical channels that can be transmitted by the wireless device on the first cell on the first frequency, wherein each of the parameter and the corresponding parameter corresponds to at least an uplink data rate, and wherein the comparison comprises determining whether a magnitude of difference, between the parameter of the determined uplink transmission configuration on the second cell on the second frequency with the corresponding parameter related to the determined uplink transmission configuration on the first cell on the first carrier, is within a threshold; and performing a cell change to the second cell based on the comparison and at least one additional criteria, wherein the at least one additional criteria depends on one or more of: whether the wireless device is in Carrier Aggregation, a type of Carrier Aggregation, and a Carrier Aggregation configuration, wherein the parameter of the uplink transmission configurations to be compared for the first and second cells is related to a maximum number of allowed uplink physical channels that can be transmitted by the wireless device and includes maximum uplink transmission block sizes for the wireless device on the first and second cells, respectively, and/or a maximum number of uplink resource blocks for the wireless device on the first and second cells, respectively. determining an uplink transmission configuration related to uplink physical channels that can be transmitted by the wireless device on the second cell on the second frequency; comparing a parameter of the determined uplink transmission configuration with a corresponding parameter of a determined uplink transmission configuration related to uplink physical channels that can be transmitted by the wireless device on the first cell on the first frequency, wherein each of the parameter and the corresponding parameter corresponds to at least an uplink data rate, and wherein the comparison comprises determining whether a magnitude of difference, between the parameter of the determined uplink transmission configuration on the second cell on the second frequency with the corresponding parameter related to the determined uplink transmission configuration on the first cell on the first carrier, is within a threshold; and performing a cell change to the second cell based on the comparison and at least one additional criteria, wherein the at least one additional criteria depends on one or more of: whether the wireless device is in Carrier Aggregation, a type of Carrier Aggregation, and a Carrier Aggregation configuration, wherein the parameter of the uplink transmission configurations to be compared for the first and second cells is related to a maximum number of allowed uplink physical channels that can be transmitted by the wireless device and includes maximum uplink transmission block sizes for the wireless device on the first and second cells, respectively, and/or a maximum number of uplink resource blocks for the wireless device on the first and second cells, respectively. <EOS>
