Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station may receive from user equipment device (UE) a random access initiation message, having a characteristic that is configured to indicate to the base station a requested size of a subsequent uplink grant to be provided by the base station for transmission of uplink data by the UE. For example, the characteristic may include a predetermined preamble included in the random access initiation message, such that a requested grant size is indicated by which preamble the UE selects from a plurality of possible preambles. As another example, the characteristic may include which RACH occasion is selected by the UE to transmit the random access initiation message. In response, the base station may allocate resources for use by the UE based on the characteristic.

Abstract: Performing a UE-triggered lower layer-based handover may include performing measurements of source gNB CSI-RS samples associated with a source gNB. Measurements of target gNB CSI-RS samples associated with a target gNB may be performed, wherein the CSI-RS samples associated with the source gNB and the CSI-RS samples associated with the target gNB are transmitted in a burst structure. A subset of the source gNB CSI-RS samples and the target gNB CSI-RS samples may be filtered using a layer 1 or a layer 2 filter. A filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples may be generated. Based on the generated filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples, determining whether a handover from the source gNB to the target gNB is to occur.

Abstract: A user equipment (UE) is configured to transmit physical uplink shared channel (PUSCH) transmissions having repetitions. The UE receives a first downlink control information (DCI) transmission from a base station of the wireless network, wherein the first DCI transmission schedules a first physical uplink shared channel (PUSCH) transmission having repetitions, transmits the PUSCH transmission with the one or more repetitions, receives a second DCI transmission from the base station, wherein the second DCI transmission indicates that the UE should modify the repetitions of the first PUSCH transmission and modifies the repetitions of the first PUSCH transmission.

Abstract: A user equipment (UE) is configured to transmit cancelled hybrid automatic repeat request (HARQ) feedback. The UE generating HARQ feedback for one or more HARQ process corresponding to a component carrier (CC), identifies that a scheduled transmission for the HARQ feedback has been cancelled and retransmits the cancelled HARQ feedback using a type 3 HARQ codebook.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE receives a configuration for a physical downlink control channel (PDCCH) including repetitions for PDCCH candidates comprising first PDCCH data, wherein the PDCCH candidates are repeated across multiple durations of a DL resource grid, detects, based on a repetition detection scheme, each of the PDCCH candidates and combines soft bits from each of the PDCCH candidates, wherein the combined soft bits are jointly decoded to determine the first PDCCH data and calculates a number of blind decodes (BDs) for the durations of the DL resource grid carrying the PDCCH candidates, wherein at least one BD value for the PDCCH candidates is scaled by a scaling factor for the calculation of the number of BDs.

Abstract: A user equipment (UE) comprising a processor configured to perform the operations that determines an uplink (UL) slot is described. In exemplary embodiments, the UE receives, from a base station, a scaling factor through a first Radio Resource Control (RRC) signal. The UE may further determines an offset through a second RRC signal. In addition, the UE may receive from the base station, downlink control information (DCI) that includes an indication of an initial time gap. Furthermore, the UE may calculate a new time gap by at least applying the scaling factor to the initial time gap and determine a slot of uplink transmission based on at least the new time gap and the offset.

Abstract: Enhanced channel state information (CSI) reporting may include encoding a CSI reporting configuration associated with a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include at least one codebook configuration. The at least one codebook may include at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. The at least one of the rank restriction configuration or the CBSR configuration may correspond to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP. A CSI measurement communication received from a user equipment (UE) may be decoded. The CSI measurement communication may be based on the decoded CSI reporting configuration.

Abstract: PUCCH carrier switching includes decoding an RRC configuration that indicates a reference cell having a reference cell slot numerology. A reference cell slot is determined for PUCCH transmissions based on the reference cell slot numerology. The determined slot is used for transmission of an SR, CSI, or HARQ-ACK, A DCI indicating a candidate target PUCCH cell having a candidate target PUCCH cell slot numerology and a slot of the candidate target PUCCH cell is decoded. A target PUCCH cell having a target PUCCH cell slot numerology is determined for transmitting the SR, the CSI, or the HARQ-ACK. The determined slot is mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource is determined for transmitting the SR, the CSI, or the HARQ-ACK using the corresponding slot of the target PUCCH cell. The PUCCH resource determination is based on a PUCCH configuration of the target PUCCH cell.
