CN-122029757-A - Dynamic adjustment of adaptive receive diversity

Abstract

Certain aspects of the present disclosure provide techniques for dynamic adjustment of Adaptive Receive Diversity (ARD). An example method performed at a User Equipment (UE) generally includes receiving configuration information that configures the UE with a first resource for receiving at least one downlink signal and a second resource for transmitting at least one uplink signal, detecting a collision between the first resource and the second resource, and dynamically adjusting an Adaptive Receive Diversity (ARD) mode if one or more conditions are met after the collision is detected.

Description

Dynamic adjustment of adaptive receive diversity Cross Reference to Related Applications The present application claims priority from U.S. patent application Ser. No. 18/491,124, filed 10/20 at 2023, which is assigned to the assignee of the present application and is hereby expressly incorporated by reference in its entirety as if fully set forth below and for all applicable purposes. Technical Field Aspects of the present disclosure relate to wireless communications, and more particularly to techniques for dynamic adjustment of Adaptive Receive Diversity (ARD). Background 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.
