Abstract: Enhanced channel state information (CSI) reporting may include encoding a CSI reporting configuration associated with a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include at least one codebook configuration. The at least one codebook may include at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. The at least one of the rank restriction configuration or the CBSR configuration may correspond to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP. A CSI measurement communication received from a user equipment (UE) may be decoded. The CSI measurement communication may be based on the decoded CSI reporting configuration.

Abstract: PUCCH carrier switching includes decoding an RRC configuration that indicates a reference cell having a reference cell slot numerology. A reference cell slot is determined for PUCCH transmissions based on the reference cell slot numerology. The determined slot is used for transmission of an SR, CSI, or HARQ-ACK, A DCI indicating a candidate target PUCCH cell having a candidate target PUCCH cell slot numerology and a slot of the candidate target PUCCH cell is decoded. A target PUCCH cell having a target PUCCH cell slot numerology is determined for transmitting the SR, the CSI, or the HARQ-ACK. The determined slot is mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource is determined for transmitting the SR, the CSI, or the HARQ-ACK using the corresponding slot of the target PUCCH cell. The PUCCH resource determination is based on a PUCCH configuration of the target PUCCH cell.

Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing vehicle-to-everything (V2X) sidelink communications with hybrid automatic repeat request (HARQ) feedback include using a new long physical sidelink feedback channel (PFSCH) format, i.e., PFSCH format 1, to assign feedback resources for various sidelink communication networks and environments where the existing or legacy sidelink feedback format, i.e., the short PFSCH format, referred to herein as PFSCH format 0, is insufficient to support effective acknowledgements (ACKs) and non-acknowledgements (NACKs) due to the limited nature of the format design.

Abstract: Systems and methods of a wireless communications system using signals not traditionally used for positioning purposes for positioning measurements in both uplink (UL) and downlink (DL) are described herein. A user equipment (UE) may generate a UE capability information message indicating one or more signal types that the LE can process for DL positioning measurements and/or that the UE can send for UL positioning measurements. The one or more signal types so indicated may include signals not traditionally used for positioning measurements. The UE may send, to the base station, the UE capability information message. The wireless communications system may then configure the base station and/or the UE to use such signal types with one or more positioning methods. In some embodiments, the base station may also indicate to the UE a subset of signals of an indicated type which should be processed for DL measurements/sent for UL measurements.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform a secondary cell (SCell) activation. A network node can send a UE a command to activate a component carrier, where this component carrier is associated with other component carriers of a component carrier group. In turn, the UE can determine one or more cross-component carrier reference signal(s) received on one or more activated component carriers of the component carrier group for use in the activation of the component carrier.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a Discontinuous Reception (DRX) switching command from a network device and switches, based on the DRX switching command, from a current first Connected Mode DRX (cDRX) configuration to a different second cDRX configuration. Each of the first cDRX configuration and the second cDRX configuration is a configuration selected from a group consisting of: a default cDRX configuration; and at least one non-default cDRX configuration. Each non-default cDRX configuration of the at least one non-default cDRX configuration comprises a cDRX periodicity and a cDRX offset corresponding to a periodicity and an offset of a Semi-Persistent Scheduling (SPS) or Configured Grant (CG) configuration, respectively.

Abstract: Apparatuses, systems, and methods for a wakeup radio in a wireless communication system, e.g., in 5G NR systems and beyond. An RRC state is introduced to support a wakeup radio/, including defining transition mechanisms to/from existing RRC states. Further, signaling is introduced to activate a wakeup radio/activate an RRC low power state. Additionally, a bandwidth part framework for a wakeup signal is defined in which a base station may configure one or more time/frequency resources or a wakeup signal for a wakeup radio. In addition, various mechanisms are introduced to switch a wakeup radio on as well as to switch a wakeup radio off. Also, mechanisms are introduced for multiplexing multiple wakeup signals in a time/frequency resource, configuring a wakeup signal bandwidth, and configuring which beam a wakeup signal may be received on.

Abstract: Disclosed is a user equipment (UE) configured to perform beam failure recovery with uplink antenna panel selection. In some embodiments, the UE determines a first UE antenna panel corresponding to a candidate beam detection (CBD) reference signal (RS); reports to a gNB a beam failure recovery request (BFRQ), the BFRQ including UE antenna panel information for the first UE antenna panel; and after receiving from the gNB a response to the BFRQ, changes from a second UE antenna panel to the first UE antenna panel and corresponding configuration for uplink transmission.
