Abstract: A repeater configured to receive, on a side control channel from a component of a network, side control information including parameters at least for determining time domain resources on which to apply an indicated beam for uplink (UL) transmission reception or downlink (DL) transmission forwarding with a user equipment (UE) on an access link, determine, from the received parameters, whether to apply the indicated beam to a transmission (Tx) spatial filter, a reception (Rx) spatial filter, or both the Tx and Rx spatial filters and apply the indicated beam to the determined Tx spatial filter, Rx spatial filter, or both the Tx and Rx spatial filters for the determined time domain resources when forwarding the DL transmission to the UE or receiving the UL transmission from the UE for forwarding to the network.

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.

Abstract: A base station and a user equipment (UE) may exchange messages to perform a Random Access Channel (RACH) procedure. The UE performs measurements on a plurality of signal synchronization blocks (SSBs), selects M physical random access channel (PRACH) groups based on one or more of the measured SSBs satisfying a predetermined threshold, provides the measurements for the M PRACH groups to a base station in an initial access transmission for a RACH procedure and monitors for a random access response (RAR) message based on a repetition number for the RAR message indicated by the base station.

Abstract: A user equipment (UE) receives scheduling information from a base station of a wireless network. The UE monitors a first physical resource to receive a common downlink control information (DCI) portion of scheduling information for the UE, decodes the common DCI portion to determine information for a UE-specific DCI portion that is transmitted by the base station on a second physical resource, monitors the second physical resource for the UE-specific DCI portion based on at least the information from the common DCI and decodes the UE-specific DCI portion based on at least the information from the common DCI.

Abstract: Embodiments herein describe systems, apparatuses, and methods for adapting physical downlink control channel (PDCCH) monitoring behaviors. In some embodiments, a network node and a UE use search space set group switching to change PDCCH monitoring behavior. In some embodiments, a network node and a UE use PDCCH skipping to change PDCCH monitoring behavior. The PDCCH monitoring behavior may be indicated in a downlink control indicator (DCI).

Abstract: A user equipment (UE) performs uplink (UL) transmissions to a network. The UE receives a frequency domain resource allocation (FDRA) configuration from a network, the FDRA configuration comprising at least one of a first FDRA mode or a second FDRA mode, wherein the first FDRA mode utilizes an FDRA unit comprising a set of consecutive resource blocks (RBs) and the second FDRA mode utilizes an FDRA unit comprising a set of interlaced RBs, when both of the first and second FDRA modes are configured, the UE receives a signal indicating which one of the two FDRA modes are to be used for an uplink (UL) transmission and performs the UL transmission in accordance with the indicated FDRA mode.

Abstract: Various systems and methods disclosed herein describe improvements for beam management that leverage virtualization across a vertical polarization (V-Pol) and horizontal polarization (H-Pol). One or more of a user equipment (UE) and a base station may include an antenna array comprising V-Pol antenna elements and H-Pol antenna elements. The UE may determine a number of receive (Rx) beam of an Rx beam sweep are needed, signal this number to the base station, and perform the beam sweep according to one or both of the V-Pol and H-Pol. A UE may use group based beam reporting to indicate to the base station a transmit (Tx) beam upon which downlink MIMO using V-Pol and H-Pol may be supported by reporting a same transmission configuration indication (TCI) corresponding to the Tx beam for both a first Rx beam and a second Rx beam in a group based beam reporting message.

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.
