Summary of the patent applications from Telefonaktiebolaget LM Ericsson (publ) on November 30th, 2023

Telefonaktiebolaget LM Ericsson (publ) has recently filed several patents related to wireless communication devices and methods. These patents cover a range of technologies and techniques aimed at improving the efficiency, reliability, and performance of wireless networks.

Some notable applications include:

• A circuit board arrangement that includes conductive material structures and a separating layer. The separating layer includes a graphene island that can stretch between the structures, allowing for electrical interconnection or separation.

• A method performed by a wireless device operating in two networks. The device determines a periodic pattern for idle/inactive mode procedures in the second network and transmits this pattern to the first network. This allows the first network to adapt the pattern for the device's procedures or account for its unavailability.

• A method in a first terminal device that transmits information to a core network node indicating that a second terminal device acting as a relay is in a Radio Resource Control (RRC) Connected state. This method establishes communication between the first terminal device and the network device through the second terminal device.

• A technique for handling radio link failures in relayed radio communication systems. This technique identifies failures and performs actions such as release, reconfiguration, or reestablishment to ensure uninterrupted and reliable communication.

• Methods and apparatuses for enabling a user equipment (UE) to perform a random access in a radio base station. This invention simplifies the random access process by providing specific information about valid channels for the preamble, improving efficiency and accuracy.

• A wireless communication device that receives a random access configuration from a radio network node. The device sends a random access preamble, and the network node responds with a random access response transmitted on one or more downlink beams.

• A method for selecting radio resources for device-to-device (D2D) transmissions in wireless communication devices. The device prioritizes subsets of radio resources using specific selection mechanisms and performs D2D transmissions on the selected resources.

• Methods for enabling coordination of resources between User Equipment (UE) devices, aiming to reduce network load and ineffective coordination messages.

• Methods for a UE to receive downlink data from a serving cell in a wireless network, considering a limited-buffer rate-matching threshold.

• Methods and apparatus for enabling 1024-constellation Quadrature Amplitude Modulation (1024-QAM), including configuring a UE to monitor a PDCCH using specific DCI formats and enabling a 1024-QAM MCS table for a serving cell.

In summary, Telefonaktiebolaget LM Ericsson (publ) has filed patents covering various aspects of wireless communication devices and methods, including circuit board arrangements, idle/inactive mode procedures, relayed radio communication, random access, resource coordination, downlink data reception, and modulation schemes. These patents aim to improve the efficiency, reliability, and performance of wireless networks.
