Abstract: Aspects are provided which allow a UE including an application processor and a modem to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may provide, using the application processor, an indication to the modem. The UE may determine whether to measure the reference signal using the modem based on the indication provided to the modem from the application processor and whether the reference signal is within the identified frequency range and further based on whether the base station is standalone or non-standalone. The UE may refrain from measuring the reference signal in response to the determination. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.

Abstract: A user equipment (UE) configured for dual connectivity with a split bearer configuration may transmit uplink data packets to one or both a master cell group (MCG) and a secondary cell group (SCG). The UE may transmit an uplink transmission from a packet data convergence protocol (PDCP) entity over one or both of a first radio link control (RLC) entity associated with the MCG and a second RLC entity associated with the SCG. The configuration including a transmit buffer threshold. The UE may receive, at the PDCP entity, an uplink switch start indication. The UE may activate the second RLC entity in response to receiving the uplink switch start indication. The UE may transmit a buffer status report according to a current transmit buffer level plus the transmit buffer threshold. Accordingly, the UE may communicate with the SCG based on the uplink switch start indication.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to how to allocate transmission power for uplink transmissions on different component carriers.
