Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interferences for Sounding Reference Signal (SRS) by, for example, one or more of frequency domain interference randomization, code domain interference randomization, or power control. For example, a user equipment (UE) can be configured to determine a comb offset and/or a cyclic shift for each Sounding Reference Signal (SRS) transmission occasion for the UE. The comb offset and/or the cyclic shift change between different SRS transmission occasions of the UE. The UE is further configured to transmit an SRS to the base station using the determined comb offset and/or the determined cyclic shift during the SRS transmission occasion corresponding.

Abstract: Some embodiments include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and sub-combinations thereof, for explicit power saving operations for a network-controlled repeater (NCR) in a wireless network. Some embodiments include an NCR that can receive a Downlink Control Information (DCI) format comprising an offset indication in a single Physical Downlink Control Channel (PDCCH) monitoring periodicity, KS, where KS is an integer of slots. The NCR can determine a single On-Off Pattern (OOP) within KS based at least on the offset indication, and communicate with a base station or a user equipment (UE) based at least on the determination. In some embodiments, an Off-State of the NCR is a default, and the offset indication identifies a duration of an On-State of the NCR beginning at a starting orthogonal frequency division multiplexing (OFDM) symbol of KS.

Abstract: Supporting transmission of multiple hybrid automatic repeat request acknowledgments (HARQ-ACKS) within a single slot may include encoding a first HARQ-ACK and a second HARQ-ACK within the single slot for transmission to a base station. The first HARQ-ACK may be transmitted via a first physical uplink control channel (PUCCH) and the second HARQ-ACK may be transmitted via a second PUCCH. Based on encoding the first HARQ-ACK and the second HARQ-ACK within the single slot, one or more additional uplink (UL) signals colliding with at least one of the first HARQ-ACK and the second HARQ-ACK within the single slot may be responded to based on a configuration of the UE.

Abstract: Some aspects relate to apparatuses and methods for implementing mechanisms for a network to trigger the UE to obtain synchronization with one or more cell neighbors in the network. Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for measuring and using TA for a beam group and for uplink signal multiplexing. For example, a UE includes a transceiver configured to wirelessly communicate with a serving cell and a processor communicatively coupled to the transceiver. The processor receives, from the serving cell, a first message indicating Physical Random Access Channel (PRACH) resource configuration associated with a neighbor cell. The processor further receives a second message to trigger transmission of a PRACH message to the neighbor cell. The processor further generates the PRACH message responsive to the second message and according to the PRACH resource configuration cell and transmits the PRACH message to the neighbor cell.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced direct secondary cell activation in a 5G wireless communications system. A user equipment (UE) can receive a Radio Resource Control (RRC) command from a 5G Node B (gNB) via a Primary Cell (PCell) or via a Primary Secondary Cell (PSCell) that includes configuration data for a Secondary Cell (SCell), where the SCell operates in Frequency Range 2 (FR2). The RRC command includes a first Transmission Configuration Indicator (TCI) state for the SCell, and the UE can activate the SCell for the UE based at least on the configuration data, concurrently with the first TCI state for receiving the PDCCH transmission. The UE can receive a Physical Downlink Control Channel (PDCCH) transmission via a first antenna beam from the SCell, where the first antenna beam is based on the first TCI state.
