摘要： A user equipment (UE) receives reference signals during a discontinuous reception (DRX) cycle to perform frequency and timing tracking or automatic gain control (AGC). The UE receives configuration information corresponding to a reference signal that is to be transmitted to a user equipment (UE) when the UE is in a first operating state, receives the reference signal from a cell of a network when the UE is in the first operating state, performs one of frequency and timing tracking or automatic gain control (AGC) using the reference signal and receives a signal from the cell during a time window that the UE is scheduled to utilize an active mode of data exchange processing.

摘要： The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.

摘要： 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.

摘要： A cell receives channel state information for multiple transmission reception points (TRPs) from a user equipment (UE). The cell selects a first transmission reception point (TRP) of multiple TRPs associated with a cell of a network, transmits a signal to a user equipment (UE) via the selected TRP, wherein the signal is configured to trigger semi-persistent CSI (SP-CSI) report at the UE and receives the SP-CSI report from the UE that includes CSI corresponding to each TRP of the multiple TRPs.

摘要： 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.

摘要： A user equipment (UE) monitors for a synchronization signal block (SSB) to synchronize with a cell of a network. The UE monitors a frequency band during a discovery reference signal (DRS) window for a synchronization signal block (SSB) transmitted by a cell of the network, determines an SSB index based on information received from the cell of the network and synchronizes with the cell based on the SSB index.

摘要： A user equipment (UE) is configured to perform rate matching for reference signals under certain conditions. The UE receives information associated with a downlink reference signal for a first radio access technology (RAT), wherein the first RAT is different than a currently camped second RAT, identifies reference signal occasions for the downlink reference signal and receives downlink control information from the second RAT via a physical downlink control channel (PDCCH).

摘要： A user equipment may use a soft acknowledgment/negative-acknowledgement (ACK/NACK) report to indicate a number of desired repetitions for Physical Downlink Shared Channel (PDSCH). In some embodiments, the user equipment may generate a soft ACK/NACK report that includes multiple bits. The multiple bits may be coded to indicate to a network node whether an allocated number of repetitions was sufficient, redundant or insufficient, and how many more repetitions are needed or desire by the UE.
