The following relates generally to wireless communication, and more specifically to techniques for using target information in wireless communications.
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 a Long Term Evolution (LTE) systems or LTE-Advanced (LTE-A) 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-OFDM (DFT-S-OFDM). A wireless multiple-access communications system may include a number of base stations or network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE).
When making a call to a target UE, a source UE may determine to use a given subscriber identity module (SIM) card based on a variety of factors such as channel quality, interference, coverage area, etc. The factors considered by the source UE, however, may only be from one perspective (e.g., the source UE perspective) and in some cases, a given SIM card may be selected by the source UE that leads to poor call quality at the target UE. For instance, a SIM card may be selected and used by a source UE for making a call to a target UE even if the selected SIM card has poor channel quality or is experiencing interference at the target UE. The selection of a SIM card that is beneficial for the source UE but not the target UE may result in poor call performance, expensive calls, or even dropped calls.
