UPLINK TRANSMISSIONS FOR DUAL CONNECTIVITY

摘要

Methods and apparatus are provided for a User Equipment (UE) configured by a Master enhanced NodeB (MeNB) for operation with dual connectivity to a Secondary eNB (SeNB) to determine a power for transmission to the MeNB and a power for transmission to the SeNB in a subframe when a total power the UE determines according to power control processes for transmission to the MeNB and for transmission to the SeNB exceeds a maximum transmission power in the subframe. Methods and apparatus are also provided for the MeNB to select one or more antenna ports the UE uses to transmit to the MeNB and inform the selected antenna ports to the UE.

1. A method comprising:
determining, by a first base station, a first percentage of a maximum User Equipment (UE) transmission power for transmissions from a UE to the first base station and a second percentage of the maximum UE transmission power for transmissions from the UE to a second base station; and signaling, by the first base station to the UE, the first percentage of the maximum UE transmission power and the second percentage of the maximum UE transmission power.
