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: A user equipment (UE) is served by a serving cell of a network and is configured to measure channel state information reference signals (CSI-RS) from a target cell. The UE receives, from the serving cell, a measurement configuration message indicating the UE is to measure CSI-RS from a target cell of the network, wherein the measurement configuration message does not include Synchronization Signal Block (SSB) information for the target cell but further comprises an indication of whether the target cell transmits SSBs. The UE determines, based on at least the measurement configuration message, a time and frequency resource on which the CSI-RS of the target cell are to be transmitted and measures the CSI-RS of the target cell.

Abstract: A base station and a user equipment (UE) communicate the configure uplink communications in a multi-transmission and reception point (multi-TRP) configured network. The UE receives an indication of multiple sounding reference signal (SRS) resources that are to be used for uplink beam tracking, wherein each SRS resource is associated with different spatial relation information, transmits SRS using the associated spatial relation information, receives an indication that a user equipment (UE) is configured with one or more beam pairs, the one or more beam pairs configured by the network based on the SRS and transmits an uplink channel based on the indicated one or more beam pairs.

Abstract: A user equipment (UE) may transmit hybrid automatic repeat request (HARQ) feedback when part of a group of UEs. The UE receives a radio network temporary identifier (RNTI) associated with a group of UEs that includes the UE. The UE monitors for a signal from one of a cell on which the UE is currently camped or a cell to which the UE is currently connected that is scrambled by the RNTI and includes control information. The UE transmits HARQ feedback to the one of the currently camped cell or currently connected cell, the HARQ feedback associated with the signal and, when the signal is received, performs an operation in response to the control information.

Abstract: This disclosure describes methods, systems, and devices for handover of a user equipment (UE) from a source node of a radio access network (RAN) to a target node of the RAN. In one example, a method involves receiving, by the UE and from the source node, a RACH-498 handover message comprising: (i) an uplink grant for establishing a connection with the target node, and (ii) an identifier of a reference signal associated with a beam of the target node. The method also involves performing, by the UE, a handover based on the RACH-less handover message.

Abstract: Exemplary embodiments include methods performed by a user equipment (UE). The methods include transmitting two transmission (Tx) streams simultaneously, wherein the two Tx streams are transmitted by two distinct Tx polarization circuitries within a same UE antenna panel circuitry as two Tx polarizations. The methods also include identifying a first signal, identifying a second signal, transmitting the first signal in a first direction using a first polarization of an antenna panel and transmitting the second signal in a second direction using a second polarization of the antenna panel.

Abstract: The exemplary embodiments describe devices, systems and methods for adaptive uplink (UL) timing adjustment for beam switching. A user equipment (UE) may perform a beam switch from a first beam to a second beam, determine a timing offset associated with the second beam and apply an uplink (UL) timing adjustment based on the timing offset associated with the second beam. In some embodiments, the timing offset may be determined based on information received after the beam switch. In other embodiments, the timing offset may be determined based on information receive prior to the beam switch.

Abstract: A system, method, and apparatus is provided for performing testing using arrival of angles (AOA). The system, method, and apparatus can receive a first test signal from a first cell; receive a second test signal from a second cell; and perform a test based on AOA of the first test signal and the second test signal. At least one of the first test signal and the second test signal can include a channel state information-reference signal (CSI-RS) signal or a synchronization signal block (SSB) signal. The first test signal can include a different number of SSBs transmitted during an Measurement Timing Configuration (MTC) window when compared to the second test signal. The system, method, and apparatus can receive the first test signal and the second test signal in a time division multiple access (TDMA) manner. The first cell can include a serving cell and the second cell can include a neighboring cell of the serving cell. The system, method, and apparatus can receive the first test signal using a main lobe of an antenna and the second test signal using a side lobe of the antenna.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for radio link monitoring for high speed user equipment (UE). For example, some embodiments are directed to a user equipment (UE) including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to monitor a downlink associated with a cell using a reference signal and estimate a downlink radio link quality associated with the downlink. The processor circuitry can further be configured to compare the estimated downlink radio link quality with a threshold. The processor circuitry can further be configured to trigger an out-of-sync operation in response to the downlink radio link quality being worse than the threshold. The threshold can include a value less than 10%.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for radio link monitoring (RLM) evaluation period and layer 1 (L1) indication interval enhancements. A user equipment (UE) uses a scaling factor to scale the RLM evaluation period and/or the L1 indication interval. Different scaling factors may be used for different scenarios, conditions, or criteria. The same or different scaling factors may be used for the RLM evaluation period and the L1 indication interval. The scaling factor or a scaling factor index may be signaled to the UE by higher layer signaling. Other embodiments may be described and/or claimed.
