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.

Abstract: Aspects herein relate to wireless devices, circuits, and methods for indicating, by a wireless device, to a wireless station, an ability to support semi-persistent (SP) measurement gap (MG) configuration; receiving, from the wireless station, a SP MG configuration; receiving, from the wireless station, a message to activate the SP MG configuration; performing, in response to receiving the message to activate the SP MG configuration, a target carrier frequency measurement, wherein the target carrier frequency measurement is performed in accordance with the activated SP MG configuration; receiving from the wireless station, a message to deactivate the SP MG configuration; and discontinuing, in response to receiving the message to deactivate the SP MG configuration, the performance of the target carrier frequency measurement. In other aspects, the wireless device may indicate, to the wireless station, an ability to support aperiodic (AP) MG configuration, which does not require explicit deactivation by the wireless station.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching. If so, the SRS transmission and/or the DL reception are changed. In a further example, the UE can supports an SRS TA capability in conjunction with the SRS Tx antenna port switching capability. In this example, SRS TA can be applied to a scheduled SRS transmission.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals based on measurement gaps. In an example, a device supports a frequency range that includes frequencies equal to or larger than 52.6 GHz. Measurement gap capability information is used to indicate and/or determine whether a measurement gap is supported for this frequency range. If so, measurement gap configuration can be defined and can include a measurement gap length and/or a measurement gap repetition period defined based on the frequencies being equal to or larger than 52.6 GHz.
