    Abstract: Methods and apparatus for Timing Advance (TA) validation are disclosed. In some embodiments, a method for wireless communication at a user equipment (UE) comprises receiving, from a base station, configuration information, where the configuration information specifying a configured grant (CG)-small data transfer (SDT) resource available for use by the UE and specifying a configuration for a Reference Signal Received Power (RSRP) change-based TA validation method to be met in order to perform a SDT while in the RRC inactive state, the RSRP change-based TA validation method having configured TA validation criteria that is evaluated based on two measurement windows for timing advance (TA) validation, and at least one boundary of at least one of the two measurement windows for TA validation is based on a minimum of either a Frequency Range 2 (FR2) measurement period and a scaled Discontinuous Reception (DRX) cycle period, existing at time of TA validation criteria evaluation.

    Abstract: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.

    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.
