Description

User equipment assisted relay of information from backscattered signals Cross Reference to Related Applications The present application claims priority from U.S. patent application Ser. No. 18/491,439, entitled "USER EQUIPMENT ASSISTED RELAY OF INFORMATION FROM BACKSCATTERED SIGNAL (USER EQUIPMENT assisted relay of information from backscattered signals)" filed on 10/20 of 2023, the entire contents of which are incorporated herein by reference. Background Technical Field Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for communicating with devices having passive radio equipment. Description of related Art Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcast, or other similar types of services. These wireless communication systems may employ multiple-access techniques that are capable of supporting communication with several users by sharing the available wireless communication system resources with those users. Despite the tremendous technological advances made over the years in wireless communication systems, challenges remain. For example, complex and dynamic environments may still attenuate or block signals between a wireless transmitter and a wireless receiver. Accordingly, there is a continuing desire to improve the technical performance of wireless communication systems, including, for example, improving the speed and data carrying capacity of communications, improving the efficiency of use of shared communication media, reducing the power used by transmitters and receivers in performing communications, improving the reliability of wireless communications, avoiding redundant transmissions and/or receptions and associated processing, improving the coverage area of wireless communications, increasing the number and types of devices that can access the wireless communication system, increasing the ability of different types of devices to communicate with each other, increasing the number and types of wireless communication media available for use, and the like. Accordingly, there is a need for further improvements in wireless communication systems to overcome the foregoing technical challenges and others.
