LG ELECTRONICS INC. patent applications published on October 26th, 2023

Summary of the patent applications from LG ELECTRONICS INC. on October 26th, 2023

• A recent patent filed by LG Electronics Inc. describes a method and device for wireless communication using a sidelink discontinuous reception (DRX) setting. The method involves receiving control information from a second device to schedule a physical sidelink shared channel (PSSCH) using a first resource within a specific active time. Data and additional control information are received through the PSSCH. A timer related to a second active time is determined based on a threshold value and time intervals between the sidelink resources, and the timer is initiated.

• Another patent filed by LG Electronics Inc. describes a method and device for transmitting and receiving data in a wireless communication system. The method involves receiving configuration information from a base station, which includes details about two sets of reference signals used for detecting beam failures. The radio link quality of these reference signal sets is assessed, and if a beam failure is detected in either set, the device performs uplink transmission to recover from the failure.

• LG Electronics Inc. has also filed a patent for a method for a user equipment (UE) in a wireless communication system to transmit a truncated Medium Access Control (MAC) Control Element (CE) report. The method involves triggering the transmission of one or more MAC CEs and receiving an uplink grant from the network. If the uplink grant does not accommodate the MAC CEs, the UE generates a MAC Protocol Data Unit (PDU) that includes a truncated MAC CE report. The UE then transmits the MAC PDU to the network, where the truncated MAC CE report contains information about MAC CEs that were triggered but not fully included in the MAC PDU.

• Additionally, LG Electronics Inc. has filed a patent for a method and apparatus for transmitting a signal in an unlicensed band in a wireless communication system. The method involves randomly selecting a value for a back-off counter within a contention window related to the unlicensed band. A first signal is then transmitted in the unlicensed band based on the back-off counter. The first signal is a sidelink signal that activates Hybrid Automatic Repeat and Request (HARQ) feedback. The size of the contention window is updated based on a feedback signal, specifically an Acknowledgement (ACK), received from multiple user equipment (UEs) for the first signal.

• Notable applications:

 * A method for a first device to perform sidelink communication, involving reserving periodic transmission resources based on a priority value.
 * A method for a user equipment (UE) in a wireless communication system to transmit a confirmation message for a configured grant (CG).
 * A method and apparatus for wireless communication between two devices, involving obtaining configuration information related to the timing of communication and monitoring specific channels for control information and data transmission.

Main Inventor

Haewook PARK

Brief explanation

This abstract describes a method and apparatus for uplink transmission and reception in a wireless communication system. In this method, a terminal receives multiple physical downlink shared channels (PDSCHs) from a base station.

The PDSCHs include semi-persistent scheduling (SPS) PDSCHs. The HARQ-ACK information for the SPS PDSCHs is determined by appending it to pre-configured HARQ-ACK information. However, any SPS PDSCH associated with a disabled HARQ process is excluded from the HARQ-ACK information included in the uplink control information.

MULTI-LINK CHANNEL ACCESS (18216921)

Main Inventor

Insun JANG

Brief explanation

In a wireless local area network (WLAN) system, there is a device called a transmitting multi-link device (MLD). This device has multiple links, with one link being the primary link and the others being non-primary links. 

When the MLD wants to transmit a PPDU (Physical Protocol Data Unit) on a non-primary link, it may choose to defer the transmission. This means that even if the back-off counter of the non-primary link reaches zero (which is a mechanism used to avoid collisions with other devices), the MLD will still wait to transmit as long as the back-off counter of the primary link has not reached zero.

During this deferral, the back-off counter of the non-primary link will be kept at zero, meaning it will not be reset or incremented. This allows the MLD to prioritize the transmission on the primary link and avoid potential collisions or interference.

Overall, this abstract describes a mechanism in a WLAN system where a transmitting multi-link device can defer the transmission on a non-primary link as long as the back-off counter of the primary link has not reached zero.

Abstract

When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.
