MAC-CE FOR JOINT SIDELINK TCI AND POWER CONTROL CONFIGURATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17479179 titled 'MAC-CE FOR JOINT SIDELINK TCI AND POWER CONTROL CONFIGURATION

Simplified Explanation

The patent application describes a method for configuring and controlling sidelink communication in a user equipment (UE) device.

• The UE receives a configuration of multiple sidelink power control parameter sets from a base station or another UE.
• The UE also receives a media access control (MAC) control element (CE) that activates transmission configuration indicator (TCI) states and indicates sidelink power control parameter sets.
• The UE receives control information that specifies a TCI state and a sidelink power control parameter set.
• Based on the TCI state, the UE transmits the sidelink communication in a specific direction.
• The transmission power for the sidelink communication is determined by the control information.

Potential applications of this technology:

• This technology can be used in wireless communication systems, such as cellular networks, to improve the efficiency and reliability of sidelink communication between devices.
• It can enable better coordination and control of sidelink transmissions, leading to improved performance in applications like device-to-device communication, vehicle-to-vehicle communication, and Internet of Things (IoT) devices.

Problems solved by this technology:

• Sidelink communication in wireless networks can suffer from interference and inefficient power control, leading to reduced performance and reliability.
• This technology solves these problems by providing a method for configuring and controlling sidelink communication parameters, such as power control, in a more efficient and coordinated manner.

Benefits of this technology:

• Improved efficiency and reliability of sidelink communication in wireless networks.
• Better coordination and control of sidelink transmissions, leading to reduced interference and improved overall network performance.
• Enhanced performance and reliability of applications that rely on sidelink communication, such as device-to-device communication and IoT devices.

Original Abstract Submitted

A user equipment (UE) may receive, from at least one of a base station or a configuring UE, a configuration of a plurality of sidelink power control parameter sets, a media access control (MAC) control element (CE) (MAC-CE) activating transmission configuration indicator (TCI) states and indicating sidelink power control parameter sets, and control information indicating a TCI state and a sidelink power control parameter set. The UE may transmit the sidelink communication in a direction based on the TCI state and with a transmission power indicated in the control information. The MAC-CE may include a joint MAC-CE or separate MAC-CEs to update or configuration of the sidelink TCI and the power control parameters.
