Method and apparatus to handle uplink (UL) information in a wireless communication system

摘要

A method and apparatus are disclosed to handle UL information. The method includes configuring a UE (User Equipment) with multiple serving cells. The method further includes transmitting, from the UE, in a subframe i a first UL control information on a physical channel of a first UL serving cell. The method also includes transmitting, from the UE, in the subframe i a second UL control information on a physical channel of a second UL serving cell, wherein if the total transmit power of the UE exceeds {circumflex over (P)}CMAX(i), the UE would scale down the transmit power of the physical channel with lower power priority based on types of the first UL control information and the second UL control information.

1. A method to handle UL (Uplink) control information, comprising:
configuring a UE (User Equipment) with multiple serving cells; transmitting, from the UE, in a subframe i a first UL control information on a physical channel of a first UL serving cell; and transmitting, from the UE, in the subframe i a second UL control information on a physical channel of a second UL serving cell; wherein if the total transmit power of the UE exceeds {circumflex over (P)}CMAX(i), which is a linear value of UE total configured maximum output power in subframe i, the UE would scale down the transmit power of the physical channel with lower power priority based on types of the first UL control information and the second UL control information, and wherein if the first UL control information type is the same as the second UL control information type, a PUCCH (Physical Uplink Control Channel) transmission would have higher priority than a PUSCH (Physical Uplink Shared Channel) transmission.
