Power headroom for simultaneous voice and long term evolution

摘要

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.

主权项

1. A method of wireless communication at a User Equipment (UE), comprising:
receiving an uplink grant; determining a first power from a shared available transmission power at the UE for simultaneously transmitting a first data signal using a first radio access technology and transmitting a second voice signal using a second radio access technology different from the first radio access technology; determining a second power from the shared available transmission power for transmitting the first data signal on an uplink using the first radio access technology based on the uplink grant; determining a difference between the first power and the second power; and reporting, upon a trigger, information related to the difference via the first radio access technology, wherein the reporting information is triggered when a change of a power backoff from a last report exceeds a threshold.
