The terminal may include a transmitter that transmits, to a second network, a terminal capability indicating support for a measurement configuration. The terminal may include a receiver that receives, from the second network, network configuration information including a pattern for establishing a second communication link with the second network. The terminal may include a processor that, based on the pattern, establishes the second communication link with the second network while maintaining the first communication link with the first network. The network configuration information may be based on an independent frequency range (FR) measurement included in the terminal capability.

Abstract: Systems and methods for analyzing a validity of an early measurement report (EMR) measurement result are described herein. A base station may configure a threshold value for EMR result validity and receive, from a user equipment (UE), a first measurement value corresponding to a first time at or before expiration of a timer associated with idle mode or inactive mode measurements. The base station receives, from the UE, a second measurement value corresponding to a second time when a radio resource control (RRC) connection setup or resume procedure starts. The base station then determines, based on a comparison of the threshold value to a difference between the first measurement value and the second measurement value, whether the EMR result is valid.

Abstract: A communication system provides reliable wideband communications with reduced power consumption in a user equipment (UE) receiver. A UE may include receiver circuitry to receive a radio frequency (RF) signal from a wireless network and output an analog baseband signal. The RF signal includes M copies of a duplicated signal in a frequency domain. The analog baseband signal includes the M copies of the duplicated signal uniformly offset from one another in the frequency domain by a bandwidth F and including a gap between adjacent copies. The UE further includes an anti-aliasing analog filter an analog to digital converter (ADC). The ADC samples an output of the anti-aliasing analog filter at a sampling frequency selected to obtain a digital baseband signal comprising a combined digital copy of the M copies of the duplicated signal folded over each other.

Abstract: Techniques discussed herein can facilitate transmission and reference signals (RS) associated with layer-1 (L1) operations outside of a configured carrier bandwidth (CBW) of a user equipment (UE). One example aspect is a UE with one or more processors configured to transmit UE capability information. The UE capability information includes a frequency separation threshold, where the frequency separation threshold represents a frequency separation from a CBW of the UE. The one or more processors are further configured to receive a RS within the frequency separation threshold and outside of the CBW, and subsequently perform a L1 operation based on the RS.
