摘要： Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform URLLC scheme selection. The UE may connect to at least one base station. The UE may determine scheduling of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) are within a threshold duration. Based on the PDCCH and the PDSCH being scheduled within the threshold duration, select one or more transmission control indicator (TCI) states for receiving the PDSCH irrespective of TCI state(s) indicated in the PDCCH. The UE may receive the PDSCH using the selected one or more TCI states.

摘要： Methods, systems, and apparatuses for synchronizing data transmission activity by user equipment (UE). In one aspect, the method comprises determining, by the UE and based on current usage of resources, that alignment of subsequent usage of resources is to be adjusted, generating, by the UE, data that indicates a plurality of activity alignment parameters that are to be adjusted in order to cause the adjusted alignment of subsequent usage of resources, encoding, by the UE, the generated data for transmission to a base station, and transmitting, by the UE, the encoded data to the base station.

摘要： A user equipment (UE), or other network component can operate to configure different sets of resources including different sequence lengths for an uplink (UL) transmission via a UL channel. A first length or at least one of different second lengths can be selected to configure the UL transmission based on one or more conditions, which can include a coexisting radio access technology (RAT), a UE capability, an occupied channel bandwidth (OCB), the type of UL transmission or the like. The UL transmission can be based on at least one of: the first or the second sequence length such as for an initial access procedure based on the coexisting RAT and the OCB, for example.

摘要： A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a physical shared channel based on a number of resource blocks determined by one or more formulas for a transport block size (TBS). In response to determining a result of the one or more formulas based on one or more received parameters a configured action for the physical shared channel can be determined based on the number of resource elements (REs). A radio frequency (RF) interface, is configured to provide, to RF circuitry, data for transmitting a new radio (NR) communication based on the configured action.

摘要： Apparatuses, systems, and methods to enhance system performance (e.g., UL throughput) without impinging on (e.g., tightening) processing timeline for UL-SCH data and/or CSI reporting. A base station may request for a UE to send a CSI report(s) during PDCCH monitoring. The base station may also request the UE to send UL-SCH data. At a first transmit opportunity, the UE may transmit first PUSCH (including UL-SCH data that may be multiplexed onto the first PUSCH). Additionally, at a second (later) transmit opportunity, the UE may transmit second PUSCH (including the CSI report(s) that may be multiplexed onto the second PUSCH). The second transmit opportunity may be identified as a transmit opportunity starting at least a specified number of symbols after a first symbol of the first repetition. The specified number of symbols may be dependent upon at least one of UE uplink processing time capabilities or SCS.

摘要： A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

摘要： A method and apparatus for a wireless device of reduced capabilities to access a wireless communication network targeted to operate with wireless device having higher capabilities is disclosed. The device may receive from abase station of the wireless communication network an indication of whether the type of devices that includes the wireless device of reduced capabilities is allowed to access the wireless communication network. The device may transmit to the base station signaling associated with connecting to the base station if the base station indicates that the type of devices with reduced capabilities is allowed to access the wireless communication network. The signaling allows the device to connect to the base station. The device may transmit capability information of the device to the base station. The device may configure its features based on the capability information to communicate with the base station.

摘要： This disclosure relates to techniques for configuring physical uplink shared channel transmissions with improved reliability in a wireless communication system. A cellular base station may establish a wireless link with a wireless device. The cellular base station may provide uplink data transmission configuration information to the wireless device. The uplink data transmission configuration information may configure an uplink data transmission to multiple transmission-reception-points. The cellular base station may receive at least a portion of the uplink data transmission.
