Abstract

Some aspects include an apparatus, method, and computer program product for radio resource management measurement prioritization for reduced capacity (RedCap) user equipment (UE). A RedCap UE may be use Half-Duplex Frequency Division Duplex (HD-FDD) for wireless communications. When performing communications with a network, the RedCap UE may make several measurements, including Reference Signal Received Power (RSRP), Signal to Interference and Noise Ratio (SINR), and Reference Signal Received Quality (RSRQ) measurements. To obtain these measurements, the RedCap UE may measure Synchronization Signal Block (SSB), Received Signal Strength Indicator (RSSI), and/or Channel State Information Reference Signal (CSI-RS) symbols. Difficulties may arise when a RedCap UE's serving cell signal timing is not synchronized with a neighboring cell. The RedCap UE may be configured to prioritize measurements over uplink transmissions. This prioritization may also include symbol buffers so that an overlap in uplink transmissions does not occur during a measurement.
