Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing designs for configurations of resource elements to carry reference signals for a user equipment (UE). A reference signal can be processed by the UE according to the configuration of resource elements to carry reference signals. The configurations can be determined by the base station, and received from the base station by the UE. The base station determines the configurations based on information or parameters provided by the UE, e.g., a coherence bandwidth of the channel, a coherence time of the channel, a preference associated with channel status information reference signal, or a preference associated with demodulation reference signal for the UE.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: A user equipment (UE) may perform sounding reference signal (SRS) switching by transmitting one or more SRS using a plurality of SRS resources of an SRS resource set configured for SRS switching according to a first combination of downlink (DL) and uplink (UL) antenna ports. For UE power saving, the UE may turn off one or more of the DL and UL antenna ports. The UE may then reconfigure the plurality of SRS resources of the SRS resource set for SRS switching according to a second combination of the DL and UL antenna ports. In response to a power saving message from a UE, a base station may generate SRS configuration information to configure an SRS resource set for SRS antenna switching based on a combination of active DL and UL antenna ports at the UE, and send the SRS configuration information to the UE.

Abstract: Techniques described herein may include new and enhanced solutions for several aspects of inter-UE communications. For example, techniques described herein may provide inter-UE coordination techniques for different types of resource sets, sensing operations for inter-UE communication, and how UEs involved in inter-UE communication may be determined. In additional, or alternative, examples, techniques described herein may provide solutions for post-collision schemes, including how certain resource sets may be applied, whether and how to jointly transmit post-collision and pre-collision indications, and how to determine the resources for post-collision indication.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: A UE for a 5G system is to perform a measurement during a network controlled small gap (NCSG). The NCSG includes a first visible interruption length (VIL1), a measurement length (ML), a second visible interruption length (VIL2), and a visible interruption repetition period (VIRP). A UE capability indicates a length of one or both the VIL1 and the VIL2. NCSG pattern information provides the NCSG for the UE, in which the VIL1 and the VIL2 indicate when the UE is not expected to transmit and receive data on a serving carrier, the ML indicates when the UE is expected to transmit and receive data on the serving carrier, and the VIRP indicates a period in which to repeat the NCSG.

Abstract: Systems and methods for using clear channel assessment (CCA) on a channel prior to transmitting the channel are disclosed. A wireless transmission system may perform omnidirectional CCA using a CCA power threshold that is calculated based on a number of synchronization signal blocks (SSBs) transmitted by the wireless transmission system per SSB burst or per synchronization signal/physical broadcast channel (SS/PBCH) block measurement timing configuration (SMTC) window, or on a number of transmit (Tx) antennas used. A wireless transmission system may perform directional CCA on one or more Rx beams that correspond to one or more intended Tx beams using CCA power thresholds calculated based on an equivalent isotropic radiated power (EIRP) of the one or more intended Tx beams to determine directional availability of the channel. A wireless transmission system may determine a CCA power threshold based on a scaling between an actual CCA bandwidth and a nominal CCA bandwidth.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to multiplex a first HARQ of a first priority and a second HARQ of a second priority to form an initial UCI payload. The UE can select a PUCCH resource accordingly to a PUCCH configuration, and generate a second UCI payload by removing or replacing at least a portion of the initial UCI payload when a size of the initial UCI payload is larger than a size of the PUCCH resource. The UE can encode at least a part of the second UCI payload including the first HARQ to generate an error correction code word. Afterwards, the UE can add the error correction code word to the second UCI payload to generate a transmission UCI payload, and transmit the transmission UCI payload to the base station.

Abstract: Layer 2 handling during a cell change procedure includes decoding an RRC reconfiguration message received from a first cell. The RRC reconfiguration message includes a Layer 1 (L1) configuration corresponding to a second cell. The first cell and the second cell share an SDAP entity, a PDCP entity, an RLC entity, and a MAC entity. The first cell and the second cell have a separate L1 entity. In response to decoding the RRC reconfiguration message, the L1 configuration corresponding to the second cell is stored. A cell change message received from the first cell is decoded. The cell change message indicates that a cell change from the first cell to the second cell is to be performed. The stored L1 configuration corresponding to the second cell is applied for data transmission and reception associated with the second cell. A cell change to the second cell is initiated.

Abstract: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.
