KR20260065818AKR 20260065818 AKR20260065818 AKR 20260065818AKR-20260065818-A

Abstract

An apparatus, method, and computer-readable medium for a user equipment (UE) in a 5G New Radio (NR) network are disclosed. The UE encodes a notification signaling indicating the ability to support simultaneous reception of two downlink (DL) signals, decodes a configuration signaling for bidirectional high-speed deployment, and decodes two DL signals received simultaneously during deployment. The reception timing difference between subframe boundaries of the DL signals is within a pre-configured maximum value. The configuration signaling includes fields for high-speed deployment type and measurements in frequency range 2 (FR2). The UE may be a Power Class 6 (PC6) device that supports simultaneous reception in FR2-1. Multiple reception chains enable simultaneous signal reception. A corresponding base station decodes the notification signaling of the UE and encodes the configuration and DL signals for transmission to the UE.

Description

Maximum reception timing difference for multi-panel receptions Claim of priority This application claims the benefit of priority to International Application No. PCT/CN2023/112218, filed on August 10, 2023, under the title of the invention “MAXIMUM RECEIVE TIMING DIFFERENCE FOR USER EQUIPMENT MULTI-PANEL RECEPTIONS”, the entirety of which is incorporated herein by reference. Mobile communications have evolved significantly from early voice systems to today's highly sophisticated integrated communication platforms. As the number of different types of devices communicating with various network devices increases, the use of 3GPP LTE systems has grown. The proliferation of mobile devices (User Equipment or UEs) in modern society continues to drive demand for various networked devices in many different environments. Fifth-generation (5G) wireless systems are scheduled for imminent release and are expected to enable much faster speeds, connectivity, and usability. Next-generation 5G networks (or NR networks) and beyond (e.g., 6G networks) are expected to increase throughput, coverage, and robustness while reducing latency and operational and capital expenditures. 5G NR (and beyond) networks will continue to evolve based on 3GPP LTE-Advanced, increasing the potential for new Radio Access Technologies (RATs) to enrich people's lives as seamless wireless connectivity solutions delivering fast and rich content and services. As current cellular network frequencies become saturated, higher frequencies, such as millimeter wave (mmWave) frequencies, may be advantageous due to their higher bandwidth. Enhanced behavior of LTE and NR systems in unlicensed spectrum as well as licensed spectrum is expected in future releases of 5G and higher communication systems. These enhanced behaviors may include techniques for configuring the Maximum Receive Timing Difference (MRTD) for user equipment (UE) multi-panel reception.
