Abstract

Technology for dual connectivity is disclosed. A user equipment (UE) can identify a first physical channel that includes a first uplink control information (UCI) and a second physical channel that includes a second UCI. The UE can select a priority level for the first physical channel and a priority level for the second physical channel. The UE can apply power scaling to a first physical channel transmission or a second physical channel transmission if a total transmit power of the UE would exceed a specific value during a period of time. The UE can scale a transmit power for the second physical channel if the priority level for the first physical channel is higher than the priority level for the second physical channel depending on a type of first UCI and a type of second UCI.

Claims8

Dependent claims

An apparatus of a user equipment (UE) configured for dual connectivity, the apparatus configured to:

process, using one or more processors and memory, a first physical channel transmission that includes a first uplink control information (UCI);
process, using the one or more processors and memory, a second physical channel transmission that includes a second UCI;
and
apply, using the one or more processors and memory, power scaling to the first physical channel transmission or the second physical channel transmission when a total transmit power of the first physical channel transmission and the second physical channel transmission from the UE exceeds a maximum transmit power (PCMAX) during a period of time, wherein:
the UE is configured to scale a transmit power for the first physical channel transmission when the first UCI does not include a hybrid automatic repeat request acknowledgement (HARQ-ACK) or scheduling request (SR) and the second UCI includes a HARQ-ACK or SR;
or
the UE is configured to scale a transmit power for the second physical channel transmission when the first UCI includes a hybrid automatic repeat request acknowledgement (HARQ-ACK) or scheduling request (SR) and the second UCI does not include a HARQ-ACK or SR.
