Abstract
A method, apparatus, and computer program product for wireless communication are provided in which a determination is made of a first power available for transmitting a first signal using a first radio access technology while simultaneously transmitting a second signal using a second radio access technology different from the first radio access technology. An uplink grant is received and a determination is made regarding a second power for transmitting the first signal on uplink using the first radio access technology based on the uplink grant. A determination is made regarding a difference between the first power and the second power. Information related to the difference is reported via the first radio access technology based on a trigger. The reporting information is triggered when the change of a power backoff from a last report exceeds a selected threshold.
