Abstract: Some embodiments include a system, method, and computer program product for managing beam switching at a higher subcarrier spacing (SCS) at millimeter wavelength (mmWave) frequencies in a 5G wireless communications system. A user equipment (UE) transmits a beam switching gap (BSG) capability to a 5G Node B (gNB). The UE receives a transmission configuration indicator (TCI) state from the gNB, and performs a beam switch to the TCI state corresponding to a first beam. The UE can receive a first control resource set (CORESET) on the first beam and a second CORESET on a second beam where the BSG occurs between the first CORESET and a second CORESET. The UE can perform beam switching within the BSG from the first beam to a second beam, and receive the second CORESET on the second beam. The UE can determine and transmit modified candidate values of beam switching parameters to the gNB.

Abstract: A user equipment (UE) is configured to use multiple beams for transmission or reception. The UE receives, from a base station, at least one medium access control (MAC) control element (CE) that indicates multiple activated transmission configuration indicator (TCI) states, receives, from the base station, at least one downlink control information (DCI) indicating a subset of TCI states of the multiple activated TCI states, wherein the MAC CE and the DCI are part of a TCI configuration, and wherein the subset of TCI states corresponds to multiple transmission and reception points (TRPs) of a wireless network, maps the subset of TCI states to the corresponding multiple TRPs based on the TCI configuration and selects a beam used for transmission or reception based on one mapped TCI state of the mapped subset of TCI states.

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: A user equipment (UE) includes a set of one or more transceivers and a processor. The processor is configured to determine, at least partly from a transmission control indicator (TCI) state for multiple channels, that common physical downlink shared channels (PDSCHs) do not share a beam with dedicated PDSCHs. The processor is also configured to determine a physical downlink control channel (PDCCH)/PDSCH scheduling offset is below a threshold; select, at least partly based on the determination that common PDSCHs do not share a beam with dedicated PDSCHs and the determination the PDCCH/PDSCH scheduling offset is below the threshold, a beam for which to buffer PDSCH; and buffer PDSCH received on the beam.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.

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 wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Abstract: Some aspects relate to apparatuses and methods for a wireless system implementing mechanisms to transmit a measurement report using physical layer (L1) carrying a sounding reference signal (SRS) reference signal received power (SRS-RSRP) measurement to provide an indication of cross link interference (CLI) between a first user equipment (UE) and a second UE. The first UE can determine a channel state information (CSI) configuration received from the base station; and configure, based on the CSI configuration, a channel measurement resource (CMR) to include a SRS received from the second UE. The first UE can measure the SRS to obtain a SRS-RSRP measurement, generate a measurement report having the SRS-RSRP measurement, and transmit the measurement report to the base station using L1.
