Abstract: A user equipment (UE) device is disclosed. The UE device comprises a processor configured to perform operations comprising receiving a downlink control information (DCI) from a base station. In some embodiments, the DCI comprises an indication to trigger a Type-3 hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback signal. The operations further comprise generating the Type-3 HARQ ACK feedback signal, based on processing the DCI. In some embodiments, the Type-3 HARQ ACK feedback signal comprises one or more HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) release(s). In some embodiments, each of the one or more HARQ-ACK bits for SPS PDSCH release(s) is adapted to include HARQ-ACK information for an SPS PDSCH release associated with the UE. Further, the operations comprise sending the Type-3 HARQ-ACK feedback signal to the base station.

Abstract: Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs. Upon determining that a portion of the maximum COT (MCOT) provided to the UE will be unused, the UE can generate COT sharing information for transmission back to the gNB. The COT sharing information identifies a starting point and a duration (e.g., a number of consecutive slots) of the unused portion of the MCOT. This information is then encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission. In aspects, the unused portion may begin part-way through a slot. In this instance, a starting symbol of the unused portion or an ending symbol of the used portion may also be encoded into the uplink transmission. In this manner, unused COT is not wasted, but rather repurposed by the gNB.

Abstract: This disclosure relates to techniques for a wireless device to perform gradual timing adjustments in a non-terrestrial wireless communication system. According to the techniques described herein, a wireless device may establish a non-terrestrial network based wireless link with a cellular base station. The wireless device may detect a trigger for changing a gradual timing adjustment rate from a first gradual timing adjustment rate to a second gradual timing adjustment rate. The wireless device may determine a time window for which to perform gradual timing adjustment at the second gradual timing adjustment rate. The wireless device may perform gradual timing adjustment at the second gradual timing adjustment rate for the time window.

Abstract: This disclosure relates to performing beam failure recovery during an inter-cell connection involving a UE in communication with one or more base stations in a cellular communication system. In various embodiments, a user equipment determines one or more beam failures by monitoring one or more reference signals transmitted by one or more base stations, where the UE is connected to the one or more base stations. The UE further performs candidate beam detection by monitoring at least one candidate reference signal that is transmitted by one or more candidate base stations, where at least one candidate base station (a first candidate base station) is different from the one or more base stations to which the UE was previously communicating. The UE selects the first candidate base station based on the candidate beam detection, and transmits a beam failure recovery request (BFRQ) message to the first candidate base station based on the selection.

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: 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 the 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%.
