EP-4735907-A1 - SIGNALING OF ASSISTANCE INFORMATION FOR SENSING ENTITIES

Abstract

A first sensing entity may receive, from a second sensing entity, a sensing information message that may include a first set of sensing attributes associated with a set of objects within an area associated with the first sensing entity. The first sensing entity may transmit a set of sensing signals at a target object. The first sensing entity may receive a set of reflected sensing signals based on the set of sensing signals and the target object. The first sensing entity may measure a second set of sensing attributes associated with the target object based on the set of reflected sensing signals and the first set of sensing attributes. The measured second set of sensing attributes may be more accurate than a set of sensing attributes that are not based on the first set of sensing attributes.

Description

SIGNALING OF ASSISTANCE INFORMATION FOR SENSING ENTITIES CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of U.S. Non-Provisional Patent Application Serial No. 18/345,818, entitled “SIGNALING OF ASSISTANCE INFORMATION FOR SENSING ENTITIES” and filed on June 30, 2023, which is expressly incorporated by reference herein in its entirety. TECHNICAL FIELD [0002] The present disclosure relates generally to communication systems, and more particularly, to a wireless sensing system. INTRODUCTION [0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems. [0004] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3 GPP) to meet new conditions associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other conditions. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements in 5G NR technology may be beneficial. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.
