Abstract: A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.

Abstract: A user equipment (UE) is configured to receive a synchronization signal block (SSB) transmission with a first subcarrier spacing (SCS) in an SSB burst window (SSBW), decode the SSB transmission to determine parameters for a control resource set 0 (CORESET #0) to be transmitted in the SSBW using a second SCS that is different from the first SCS, monitor physical downlink control channel (PDCCH) candidates in the determined CORESET #0 based on a mapping between the SSB transmission and the CORESET #0 and decode the PDCCH and a system information block 1 (SIB1) scheduled by the PDCCH in the SSBW.

Abstract: A user equipment (UE) is connected to a wireless network and operates in a carrier aggregation (CA) state that includes a first connection to a primary cell and a second connection to a secondary cell. The UE determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (BFR) operation. The BFR operation includes transmitting, to the primary cell, a BFR Medium Access Control (MAC) Control Element (CE).

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: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig indicates up to L CSI reference signal (CSI-RS) ports for selection by the UE out of P CSI-RS ports configured for measuring and reporting CSI. The UE determines selected CSI-RS ports out of the P CSI-RS ports. The selected CSI-RS ports include the L CSI-RS ports or less. The UE generates a port selection matrix W1 corresponding to the selected CSI-RS ports. The UE also generates an indication of the port selection matrix W1 to the base station. The CSI-ReportConfig may further configure the UE to select a subset of frequency basis. The UE determines a selected subset of frequency basis and generates a frequency basis selection matrix Wf corresponding to the selected subset of frequency basis.

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 aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to transmit a configured grant (CG) physical uplink shared channel (PUSCH) including an uplink control information (UCI) without transmitting a physical uplink control channel (PUCCH). The UE determines, based on a configuration received from the base station, a first set of CG PUSCHs. Each CG PUSCH of the first set of CG PUSCHs overlaps with the PUCCH, and is configured to transmit data from the UE to the base station. The UE further determines a second set of CG PUSCHs by excluding a third set of CG PUSCHs from the first set of CG PUSCHs. and select a CG PUSCH from the second set of CG PUSCHs to carry the UCI contained in the PUCCH. The UE further transmits the selected CG PUSCH including the UCI without transmitting the PUCCH.
