Description
Cell-by-cell measurement prioritization Cross Reference to Related Applications This patent application claims priority from U.S. non-provisional patent application No. 18/491,234, entitled "MEASUREMENT PRIORITIZATION BY CELL (prioritization of measurements by cell)" filed on day 10 and 20 of 2023, which is hereby expressly incorporated by reference. Technical Field Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for measurement prioritization by cell. Background Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple-access techniques capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access techniques 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, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the third generation partnership project (3 GPP). A wireless network may include one or more network nodes that support communications for wireless communication devices, such as User Equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink and uplink communications. "downlink" (or "DL") refers to the communication link from the network node to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communications, such as via local links (e.g., side Link (SL), wireless Local Area Network (WLAN) link, and/or Wireless Personal Area Network (WPAN) link, etc.). The multiple access techniques described above have been employed in various telecommunications standards to provide a common protocol that enables different UEs to communicate at a city, country, region, and/or global level. The New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3 GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, reducing costs, improving services, exploiting new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), CP-OFDM and/or single carrier frequency division multiplexing (SC-FDM) on the uplink (also known as discrete fourier transform spread OFDM (DFT-s-OFDM)) for better integration with other open standards, and supporting beamforming, multiple Input Multiple Output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful.
