Title: Liwei Qiu - Innovator in Mobile Communication Technologies

Introduction: Liwei Qiu is an accomplished inventor based in Täby, Sweden. He is currently associated with Telefonaktiebolaget LM Ericsson (publ), a leading company in telecommunications. Although he has not yet been granted any patents, his contributions to the field of mobile communication are noteworthy.

Latest Patent Applications: Liwei Qiu has been involved in several innovative patent applications. One of his latest applications is titled "Configuring Layer 1 and Layer 2 Mobility Based on Measurement Reports While in a Connected State." This method involves a user equipment (UE) in a connected state configuring Layer 1/Layer 2 (L1/L2) based inter-cell mobility. The process includes transmitting a Measurement Report with measurements related to various cells. The UE then receives a Radio Resource Control (RRC) Reconfiguration message that includes configurations for L1/L2 based inter-cell mobility candidate cells. Finally, the UE transmits an RRC Reconfiguration Complete message.

Another significant application is "Configuring Inter-DU L1/L2 Mobility Candidates." This method describes how a UE communicates with a radio access network (RAN) node, which consists of a central unit (CU) and a distributed unit (DU). The UE receives a reconfiguration message from the CU via the DU, which includes configurations for candidate cells for L1/L2-based inter-cell mobility. The UE stores these configurations and receives a lower layer signaling message that commands it to change its serving cell to a first candidate cell. The UE then performs an L1/L2 mobility procedure towards this candidate cell and communicates according to the stored configuration.

Conclusion: Liwei Qiu is a promising inventor in the field of mobile communication technologies, with a focus on enhancing inter-cell mobility. His innovative approaches in configuring mobility for user equipment demonstrate his commitment to advancing telecommunications.
