Description

FIELD OF DISCLOSURE The present disclosure, for example, relates to wireless communications, more particularly to techniques for enhanced handling of network measurements. BACKGROUND Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE). A UE may measure frequency bands and transmit measurement reports of the frequency bands to a base station. However, the UE may not measure the frequency bands in any order, which may lead to reporting of lower quality frequency bands. US 2015/281989A1 discloses a user equipment (UE) that transmits measurement reports, and postpones the transmission of a measurement report when a neighbor cell signal strength is greater than the signal strength of the target cell(s). In one instance, the UE identifies a target cell having the strongest signal strength. In another instance, the UE postpones a transmission of a measurement report for a target cell when a neighbor cell signal strength is greater than the strongest target cell signal strength and the strongest target cell signal strength is below an absolute threshold value. US 2017295574 A1 discloses wireless communication systems that can use numerous frequencies but measure a smaller number of frequencies. They may benefit from enhanced frequency selection. A method can include identifying a set of possible frequencies for measurement by a user equipment. The method can also include selecting a subset of frequencies from the possible frequencies based on parameters configured by an operator. The method can additionally include causing communication of the selection to the user equipment in a list. US 2016/205573 A1 discloses a method of wireless communication that includes delaying transmission of a first RAT measurement report, when a first time to trigger (TTT) timer for a first RAT expires, until a second TTT timer of a second RAT expires or resets. The method may include transmitting a second RAT measurement report when the second TTT timer expires. The method may also include transmitting the first measurement report when the second TTT timer resets and the first TTT timer is active. EP 3 454 602 A1 discloses a method of wireless cell evaluation for handover, and apparatus and system for same, comprising configuring a first timer for signal measurement of a first neighboring cell; performing a signal measurement on the first neighboring cell during the first timer; configuring one or more additional timers for signal measurement of one or more additional neighboring cells; performing a signal measurement on the one or more additional neighboring cells during the one or more additional timers; determining a subset of the one or more additional neighboring cells according to a measurement progress criterion; evaluating the first cell and the subset of cells for handover according to a sorting criterion; and generating a measurement report according to the evaluation for handover, comprising at least one cell within the first subset.
