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: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of a physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.

Abstract: A base station of a network configures a first search space having a first search space identification (SearchSpaceld) in a special cell (SpCell) and a second search space having a second search space identification (SearchSpaceld) in a secondary cell (SCell) for monitoring control signaling that schedules operations on the SpCell. The base station transmits a radio resource control (RRC) configuration to a user equipment (UE) including the first SSID and the second SSID, wherein the RRC configuration configures the UE to monitor the first search space having the first SSID for scheduling of a first type of control signaling and the second search space having the second SSID for scheduling of a second type of control signaling.

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.
