POWER HEADROOM REPORT FOR SIMULTANEOUS TRANSMISSIONS ON DISPARATE RADIO ACCESS TECHNOLOGIES

摘要

A method, an apparatus, and a 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 and the information related to the difference via the first radio access technology is reported based upon a trigger.
