    Abstract: Systems, methods, and apparatuses disclosed herein can generate and report a cross link interference (CLI) report. These systems, methods, and apparatuses can receive a CLI report configuration that outlines requirements for the CLI report, where the CLI report configuration is received on Layer 1 signaling, for example, Downlink Control Information (DCI) on a Physical Downlink Control Channel (PDCCH) or Layer 2 signaling, for example, downlink (DL) Media Access Control-Control Element (MAC-CE) on Physical Downlink Shared Channel (PDSCH). The CLI report configuration can identify the one or more CLI measurement resources to be measured and reported; one or more CLI measurements to be performed on the one or more CLI measurement resources; one or more CLI measurement occasions to measure the one or more CLI measurement resources; and one or more resources, to be used to report the CLI report. These systems, methods, and apparatuses can generate the CLI report as outlined in the CLI report configuration. Thereafter, these methods, and apparatuses can report the CLI report on Layer 1 signaling, for example, Uplink Control Information (UCI) on a Physical Uplink Control Channel (PUCCH) or Layer 2 signaling, for example, uplink (UL) Media Access Control-Control Element (MAC-CE) on Physical Uplink Shared Channel (PUSCH).

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing unified RACH for multiple features. For example, some aspects of this disclosure relate to a method including determining, by a user equipment (UE), a feature to be indicated at an initial access of the UE to a base station and determining whether the UE and the base station support feature specific random access (RA) procedure for the feature. The method further includes determining whether a condition for the feature is satisfied in response to determining that both the UE and the base station support the feature specific RA procedure for the feature. In response to determining that the condition is satisfied, the method includes selecting a feature specific Random Access Channel (RACH) resource and perform a 4-step RA procedure or a 2-step RA procedure based on the selected feature specific RACH resource.

    Abstract: Some embodiments include an apparatus, method, and computer program product for implementing Channel State information (CSI) feedback for multi-Physical Downlink Shared Channel (PDSCH) transmissions in a wireless communication system. Some embodiments enable a user equipment (UE) to determine Channel Quality Indicators (CQI) and/or Precoding Matrix Indicators (PMI) for multi-PDSCH transmissions that account for effects of a duration of the multi-PDSCH transmission including the maximum interval between the first and last PDSCH transmissions on the CQI and PMI determinations. Some embodiments include a base station that detects a need for a change in a beam direction and adjusts the beam direction accordingly based on the PMI determinations. Some embodiments enable a desired hybrid automatic repeat request (HARQ)-ACK feedback transmission from a single multi-PDSCH transmission. Some embodiments include performing HARQ bundling with an update to the Type 1 HARQ-ACK codebook based on the multi-PDSCH transmission.

    Abstract: A user equipment (UE) configured to report Channel State Information (CSI) to a wireless network. The UE transmits a first sounding reference signal (SRS) on an uplink (UL) channel, receives a first channel state information reference signal (CSI-RS) on a downlink (DL) channel, wherein the first CSI-RS includes a first configuration of CSI-RS parameters based on the first SRS, performs first CSI-RS measurements based on the first configuration of CSI-RS parameters, transmits a first CSI report including the first CSI-RS measurements, transmits a second SRS on the UL channel, receives a second CSI-RS on the DL channel, wherein the second CSI-RS includes a second configuration of CSI-RS parameters based on the second SRS, performs second CSI-RS measurements based on the second configuration of CSI-RS parameters and transmits a second CSI report including the second CSI-RS measurements.

    Abstract: A user equipment (UE) is configured to receive from a base station a semi-persistent scheduling (SPS) configuration for physical downlink shared channel (PDSCH) transmissions wherein multiple PDSCHs are transmitted within a single period of the SPS, the SPS configuration including a parameter for a number of hybrid automatic repeat request (HARQ) processes associated with the SPS configuration, receive from the base station a downlink control information (DCI) transmission for activating the SPS configuration, the DCI including a HARQ process ID for one of the PDSCH transmissions in the SPS configuration, wherein the UE determines a maximum number of PDSCH transmissions allowed within the single period based on the parameter for the number of HARQ processes associated with the SPS configuration, validate the DCI to determine time domain resources to use for the PDSCH transmission and receive from the base station the multiple PDSCH transmissions within the single SPS period.

    Abstract: Some embodiments include an apparatus, method, and computer program product for facilitating processing times in a 5G wireless communications system. When operating at higher frequency subcarrier spacing (SCS), slot times for receiving and/or transmitting data between user equipment (UE) and a 5G Node B (gNB) become shorter. Because of this, some UE may face difficulty in processing physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), and/or physical downlink control channel (PDCCH) data with sufficient speed. To address potential limitations, a flexible minimum processing time may be used to accommodate different UE processing capabilities. The UE may report its processing capabilities to the gNB. The gNB may then schedule communications according to the UE’s processing capabilities. The gNB may consider whether the UE implements a single or multiple processing engines. Further, the gNB may apply single-slot and/or multi-slot scheduling techniques to also prevent timing issues.

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing resource allocations for feedback channels in sidelink communications. A UE can be configured to receive a physical sidelink control channel (PSCCH) transmission or a physical sidelink shared channel (PSSCH) transmission over a sidelink between the UE and a second UE for sidelink communication. The UE can allocate a set of resource elements within an interlace including multiple resource blocks to carry physical sidelink feedback channel (PSFCH) content associated with the received PSCCH transmission or PSSCH transmission, where the set of resource elements includes a first resource element in a first resource block of the interlace, and a second resource element in a second resource block of the interlace. The UE can be further configured to transmit the PSFCH content carried by the set of resource elements as a PSFCH transmission to the second UE.
