His innovative work has led to the development of a patent that enhances communication efficiency.
Latest Patents
Johansson holds a patent for "Reliable multicast transmission with compact protocol stack." This invention provides apparatus and methods for reliable multicast transmission using a compact protocol stack. One of the novel aspects of this patent is the configuration of compact protocol stacks for both the User Equipment (UE) and the base station, which handle both the Point-to-Multipoint (PTM) Radio Bearer (RB) and the Point-to-Point (PTP) RB. The compact protocol stack can be configured as either a compact Radio Link Control (RLC) entity or a compact Packet Data Convergence Protocol (PDCP) entity. The UE monitors a PTM Logical Channel (LCH) and a PTP LCH, sending feedback to the network through the PTP RB. The base station transmits Multimedia Broadcast/Multicast Service (MBS) data packets in PTM mode to one or more subscriber UEs, monitors feedback reports from each subscriber UE through the corresponding PTP RB, and retransmits MBS data packets based on the feedback reports. Additionally, PTM-to-PTP and PTP-to-PTM mode switches are performed when triggering events are detected, with notifications sent to UEs via MAC Control Element (CE) or RLC control Protocol Data Units (PDUs).
