摘要: First transmission power can be determined (1110) for a first PRACH preamble in a 2-step random access procedure based on a first set of power control parameters. The first PRACH preamble can be transmitted (1120) in the 2-step random access procedure based on the first transmission power. A determination can be made (1130) to switch from the 2-step random access procedure to a 4-step random access procedure. Second transmission power can be determined (1140) based on the first set of power control parameters and a second set of power control parameters for a subsequent second PRACH preamble transmission for the 4-step random access procedure. The subsequent second PRACH preamble can be transmitted (1150) in the 4-step random access procedure based on the second transmission power.

摘要: Apparatuses, methods, and systems are disclosed for selective retransmission of groupcast data. One apparatus includes a transceiver that transmits groupcast data via sidelink communication to a set of UEs and receives negative acknowledgement feedback via sidelink communication from at least one UE of the set, the negative acknowledgement feedback indicating unsuccessful reception of the groupcast data. The apparatus includes a processor that determines a retransmission mode based on a number of UEs sending negative acknowledgement feedback and controls the transceiver to send selectively beamformed retransmission of the groupcast data according to the determined retransmission mode.

摘要: A first indication can be received from at least one first of a first set of TRPs of a network. The first indication can indicate a minimum scheduling offset (Kmin) value between scheduling DCI of the first set of TRPs and a corresponding data communication. A second indication indicating the Kmin value can be indicated to at least one second TRP of a second set of TRPs of the network. First and second scheduling DCI can be received scheduling respective first and second data communications associated with the respective first and second sets of TRPs. The first and second data communications can be communicated with the respective first and second sets of TRPs of the network such that the offset between the first scheduling DCI and the first data communication is at least the Kmin value and the offset between the second scheduling DCI and the second data communication is at least the Kmin value.

摘要: Apparatuses, methods, and systems are disclosed for identifying synchronization signal/physical broadcast channel block occasions. One method includes identifying a plurality of synchronization signal/physical broadcast channel block occasions configured to enable reception of a plurality of synchronization signal/physical broadcast channel blocks. A first number of synchronization signal/physical broadcast channel block occasions of the plurality of synchronization signal/physical broadcast channel block occasions is greater than a maximum allowed number of synchronization signal/physical broadcast channel blocks of the plurality of synchronization signal/physical broadcast channel blocks. The method includes receiving the plurality of synchronization signal/physical broadcast channel blocks on a portion of the plurality of synchronization signal/physical broadcast channel block occasions.

摘要: A method and apparatus communicate a transport block in an unlicensed uplink transmission on a wireless network. Downlink Control Information (DCI) can be sent on a control channel. The DCI can schedule an unlicensed uplink (UL) transmission for a UE. The DCI can include a field that indicates whether the UE should apply a scaling factor when determining a Transport Block Size (TBS). A transport block can be received in the unlicensed UL transmission based on the sent DCI.

摘要: Apparatuses, methods, and systems are disclosed for random access skip configuration. One method includes receiving a handover command message from a first cell, wherein: the handover command message includes first information that indicates a configuration of a second cell, random access channel resources on the second cell, and a first reference signals associated with the second cell; each of the first reference signals is associated with a random access channel resource; second information indicates skip configurations and second reference signals are associated with the second cell; and each of the second reference signals is associated with a random access skip configuration. The method includes receiving a first set of downlink reference signals and a second set of downlink reference signals. The method includes, selecting a first downlink reference signal and determining whether to perform a random access procedure.

摘要: Apparatuses, methods, and systems are disclosed for synchronization signal block selection. One method includes receiving multiple synchronization signal blocks on a first wideband carrier. Each synchronization signal block includes at least one synchronization signal and a physical broadcast channel. The method includes detecting at least one synchronization signal block of the synchronization signal blocks, determining at least one synchronization signal frequency associated with the at least one detected synchronization signal block, and selecting a first synchronization signal block of the at least one detected synchronization signal block and a first synchronization signal frequency of the at least one synchronization signal frequency. The first synchronization signal block is associated with the first synchronization signal frequency. The method includes decoding a first physical broadcast channel of the first synchronization signal block, and determining whether to reselect the first synchronization signal block based on a result of decoding the first physical broadcast channel.
