Abstract

Aspects of the disclosure are directed to method of selecting receive beams using a neural network (e.g., via a reinforcement learning process). In some examples, a user equipment (UE) may select one or more receive beams for receiving synchronization signal blocks (SSBs) of a first synchronization signal burst set (SSBS). In some examples, the UE may measure a power of a first SSB of the first SSBS received via a first receive beam of the one or more receive beams. In some examples, the UE may store, in a local storage, the measured power of the first SSB and at least one parameter associated with receiving the first SSB.

Description

MULTIPLE ACCESS POINT (AP) ASSOCIATION CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of US Non-provisional Patent Application Number 18/348,325 titled “MULTIPLE ACCESS POINT (AP) ASSOCIATION,” filed July 6, 2023, which is incorporated herein by reference in its entirety. BACKGROUND Technical Field [0002] The present disclosure generally relates to communication systems, and more particularly, to association between a wireless device and multiple access points (APs). 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 requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 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. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.
