Abstract: Embodiments of the present disclosure provide a rotor, a motor, a powertrain, and a vehicle. The rotor includes wedges and pole shoes. The wedges fit the pole shoes through curved portions. The curved portions can effectively relieve stress concentration of joint portions, increase strength of the wedges and the pole shoes, and effectively increase effective winding space of slots in the rotor. In this way, power density of a motor in which the rotor is used is increased.

Abstract: A wireless device receives a first downlink control information (DCI) indicating a transmission configuration indicator (TCI) codepoint that indicates a first TCI state and a second TCI state. The wireless device receives a second DCI comprising a sounding reference signal (SRS) resource set field indicating to apply one or both of the first TCI state and the second TCI state to a physical uplink shared channel (PUSCH) transmission. A value of the SRS resource set field is one of: a first value indicating to apply the first TCI state, a second value indicating to apply the second TCI state, and a third value indicating to apply the first TCI state and the second TCI state. The wireless device transmits repetitions of the PUSCH transmission based on the value of the SRS resource set field.

Abstract: A wireless device receives parameters, including a first discontinuous reception (DRX) configuration associated with unicast transmissions in a cell and a second DRX configuration associated with multicast and broadcast services (MBS) in the cell. The wireless device may also receive a power saving (PS) indication indicating not to start a DRX on duration timer. The PS indication may be applied for the first DRX configuration; and it may not be applied for the second DRX configuration. The wireless device may further skip monitoring, in a first DRX on duration of the first DRX configuration, first physical downlink control channels (PDCCHs) for the unicast transmissions based on receiving the PS indication. The wireless device may also monitor, in a second DRX on duration of the second DRX configuration and while skipping monitoring the first PDCCHs in the first DRX on duration, second PDCCHs for the MBS.

Abstract: Control information may be used to schedule communications between a wireless device and a base station. The wireless device may monitor control channels associated with one or more cells to receive the control information.

Abstract: A wireless device receives one or more messages comprising configuration parameters for a cell group. The cell group comprises: a first secondary cell configured with one or more beam failure recovery (BFR) parameters; and one or more second cells configured to use the first secondary cell for a BFR procedure. A deactivation timer of the first secondary cell is restarted in response to receiving a physical downlink control channel indicating an uplink grant or a downlink assignment for any secondary cell, other than the first secondary cell, in the cell group.

Abstract: A first wireless device receives, from a second wireless device, sidelink control information comprising a field with a value indicating to transmit a report message comprising preferred radio frequency resources of a sidelink between the first wireless device and the second wireless device. In response to the value of the field indicating to transmit the report message, the first wireless device transmits, to the second wireless device and via a physical sidelink shared channel of the sidelink, the report message indicating radio frequency resources preferred by the first wireless device. The first wireless device receives, from the second wireless device, sidelink transport blocks via one or more resources of the preferred radio frequency resources.

Abstract: A base station may communicate with a wireless device. A message may be used to indicate information for a layer 1 and/or layer 2 triggered mobility (LTM) procedure. For example, a medium access control (MAC) control element (CE) may indicate various information such as a target cell for the LTM procedure, whether to perform a random access (RA) procedure toward a target cell, a TA value, a bandwidth part (BWP) of BWPs of the target cell, and/or other information associated with the LTM procedure.

Abstract: A wireless device may communicate with a base station via a cell. A cell may be selected for wireless communications based on having a configuration that is capable of serving certain wireless resources associated with a wireless device. A wireless device may select a cell that comprises a communication link supporting certain wireless resources that may be required for use by the wireless device.

Abstract: A base station and/or a wireless device may communicate using a plurality of transmission beams. Multiple transmission beams may be used for transmission such that a message may be sent via different transmission beams. Multiple transmission beams may be used for sending multiple repetitions of the message or for sending different portions of the message.

Abstract: A wireless device may perform a listen-before transmit (LBT) procedure for an uplink transmission. An LBT failure recovery procedure may be initiated based on a failure of one or more LBT procedures. The LBT failure recovery procedure may be aborted and/or canceled based on one or more conditions, such as receiving configuration (or reconfiguration) parameters, receiving an indication of a bandwidth part switching, deactivating a cell, and/or receiving a request to set (or reset) a communication layer of the wireless device.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A wireless device may distribute power for various transmission types based on a priority, which may be received from a base station.

Abstract: A wireless device receives, from a base station, one or more radio resource control (RRC) messages that includes one or more configuration parameters for a cell. The one or more configuration parameters include a unified transmission configuration indicator (TCI) state type parameter that indicates a unified TCI state type among a separate unified TCI state type and a joint unified TCI state type. The wireless device may then communicate, with the base station and via the cell, based on the indicated unified TCI state type.

Abstract: Uplink resources for semi-persistent channel state information (SP-CSI) reports and other uplink transport block transmissions may be managed. If resources allocated to the SP-CSI reports overlap, in time, with resources allocated to the uplink transport block transmissions, a determination of whether to drop an SP-CSI report may be made. Various selection criteria may be used to make this determination.

Abstract: This application discloses a data writing method, device, a storage server and a computer readable storage medium, including: writing, when a write request is received, write data corresponding to the write request to a write buffer; acquiring historical access data of a data block corresponding to to-be-flushed data in the write buffer when a data flushing operation is triggered for the write buffer; determining whether the to-be-flushed data is write-only data based on the historical access data by using a pre-trained classifier; if yes, writing the to-be-flushed data to a hard disk drive; and if no, writing the to-be-flushed data to a cache. The data writing method provided by this application can effectively reduce the traffic of writing dirty data to the cache while reserving more space in the cache for the ordinary data, thereby improving the utilization of the cache space and the read hit rate of the cache.

Abstract: Wireless resource determination and use are described. A wireless device may determine to use a resource (e.g., PUCCH resource), indicated by control information (e.g., DCI), for sending an acknowledgement (e.g., HARQ-ACK feedback) of a reception of data (e.g., at least one transport block). The control information may be received in a message of a plurality of messages. The wireless device may select the control information (e.g., for determining the resource) from among other control information in the plurality of messages, based on one or more factors.

Abstract: Beam failure recovery (BFR) procedures for wireless communications are described. When beam failures occur on secondary cells, wireless devices may trigger a BFR procedure via an uplink resource for BFR. If a beam failure occurs for a secondary cell at a time that a wireless device does not have an uplink resource for BFR, the wireless device may perform one or more other actions for BFR of the secondary cell.
