摘要： Apparatuses and methods for physical random access channel (PRACH) preamble transmissions or receptions. A method of a UE includes receiving a physical downlink shared channel (PDSCH) that provides a system information block (SIB). The SIB includes an indication for (i) a first transmission configuration indication (TCI) state that provides a first set of quasi-collocation (QCL) properties and (ii) for a second TCI state that provides a second set of QCL properties. The method further includes transmitting a first PRACH according to the first TCI state and a second PRACH according to the second TCI state.

摘要： Reception or transmission of physical downlink control channels (PDCCH) associated with a master node (MN) or with a secondary node (SN) involve an indication for a first number of cells Ncells,MCGcap and for a second number of cells Ncells,SCGcap. A first total number of PDCCH candidates is determined on Ncells,MCGDL,μ cells of the MN over a time period according to Ncells,MCGcap and a second total number of PDCCH candidates is determined on Ncells,SCGDL,μ cells of the SN over the time period according to Ncells,SCGcap. μ is a subcarrier spacing (SCS) configuration for an active bandwidth part (BWP) on each of the Ncells,MCGDL,μ cells or Ncells,SCGDL,μ cells.

摘要： Beam measurement and reporting by a user equipment (UE) includes receiving configuration information for a channel state information (CSI) framework from a base station (BS) and identifying reporting settings and resource settings configured for the UE based on the received configuration information. The reporting settings configure a beam measurement and reporting configuration. The resource settings configure one or more reference signal (RS) resources for beam measurement. Each of the RS resources represents a transmit (Tx) beam. The method further includes performing beam measurement based on the identified reporting and resource settings, generating a CSI report based on the identified reporting and resource settings, and transmitting the generated CSI report to the BS.

摘要： A user equipment, a base station, and a method for determining search space sets for PDCCH monitoring. The UE includes a receiver and a processor and is configured to receive a configuration for search space sets. The configuration includes a first group of search space sets, a second group of search space sets, a first group index for the first group of search space sets, and a second group index for the second group of search space sets. The UE is also configured to determine an indication corresponding to either the first group index or the second group index, and to receive, based on the indication, physical downlink control channels (PDCCHs) according to either the first group of search space sets or the second group of search space sets.

摘要： A method of a user equipment (UE) operating with a new radio (NR) radio access technology (RAT). The method comprises receiving synchronization signals and a master information block (MIB) in a first bandwidth (BW) and receiving a physical downlink control channel (PDCCH) in a second BW, wherein the second BW is indicated by an offset in the MIB relative to the first BW and the PDCCH conveys a downlink control information (DCI) format that configures a reception of a first system information block (SIB).

摘要： A user equipment (UE), a base station (BS), and a method for managing UE operation in C-DRX. The UE includes a transceiver configured to receive configurations for a drx-onDurationTimer, search space sets for reception of a PDCCH, a first set of CSI-RS resources, SS/PBCH blocks, and a PUCCH resources; and the PDCCH that provides a DCI format including a field indicating whether or not to start the drx-onDurationTimer. A processor is configured to determine an indication by the field to not start the drx-onDurationTimer, and determine reception occasions for the first set of CSI-RS resources during the ON duration. The transceiver is configured to receive the first set of CSI-RS resources or the SS/PBCH blocks during at least one of the reception occasions. The processor is also configured to determine a CSI report based on a reception occasion, which can be transmitted using the PUCCH resource during the ON duration.

摘要： Apparatuses and methods for power determination for physical uplink control channel transmission with acknowledgement information. A method for operating a user equipment (UE) includes determining a sum of: a first number of received transport blocks (TBs) associated with a first set of radio network temporary identifiers (RNTIs), a second number of received TBs associated with a second set of RNTIs, and a third number of non-received TBs associated with the second set of RNTIs. The method further includes determining a power for a physical uplink control channel (PUCCH) transmission based on the sum and transmitting the PUCCH using the power. The PUCCH includes first hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits associated with the first set of RNTIs and second HARQ-ACK information bits associated with the second set of RNTIs.

摘要： A method for a user equipment (UE) to receive physical downlink control channels (PDCCHs) is provided. The UE receives configuration information for a first control resource set that includes a number of symbols in a time domain and a number of resource blocks (RBs) in a frequency domain, configuration information indicating a first number of Nbundle,1 frequency-contiguous RBs, and a PDCCH in the first control resource set in a number of frequency distributed blocks of Nbundle,1 RBs. The UE assumes that a demodulation reference signal associated with the reception of the PDCCH has a same precoding over the Nbundle,1 RBs. A method for constructing a search space to reduce a number of channel estimations that the UE performs for decoding PDCCHs, relative to conventional search spaces, is also provided.
