摘要： Methods and apparatuses for PDCCH reception and transmission. A method for PDCCH reception includes transmitting a capability for receptions of PDCCHs on a downlink (DL) cell. PDCCH receptions on the DL cell are according to (X1, Y1) or (X2, Y2) when any two PDCCH receptions are within Y1 or Y2 symbols or have first symbols separated by at least X1 or X2 symbols, respectively. The method further includes receiving a configuration of search space sets for PDCCH receptions on the DL cell; determining, based on the configuration of the search space sets, whether PDCCH receptions are according to (X2, Y2); and receiving on the DL cell: a maximum number of MPDCCHmax,X1,μ PDCCHs within Y1 symbols when PDCCH receptions are not according to (X2, Y2), and a maximum number of MPDCCHmax,X2,μ PDCCHs within Y2 symbols when PDCCH receptions are according to (X2, Y2).

摘要： Methods and apparatuses for cell selection for uplink transmission. A method for operating a user equipment includes receiving: a bitmap mapping to a number of slots on a primary cell. The mapping repeats periodically over the number of slots. The bitmap indicates the primary cell or a secondary cell. The method further includes receiving information for first parameters associated with transmission of a physical uplink control channel (PUCCH) on the primary cell and information for second parameters associated with transmission of a PUCCH on the secondary cell. The method further includes determining, based on the bitmap, a first cell to transmit a first PUCCH in a slot of the first cell and transmitting the first PUCCH in the slot on the first cell.

摘要： Methods and apparatuses for UL reference signal-based beam management. A method of operating a UE includes receiving configuration information for UL reference signals for beam management, source reference signals for spatial relation, and a beam report; receiving the source reference signals; and measuring a signal quality metric for the source reference signals for spatial relation. The method further includes transmitting a beam report based on measured signal quality metric and receiving, in response to the beam report, updated configuration information for the UL reference signals for beam management. The method further includes determining a time for update of the UL reference signals for beam management and transmitting the UL reference signals for beam management based on the updated configuration information at the determined time.

摘要： A method of a user equipment (UE) for transmitting acknowledgement information. The method comprises receiving a physical downlink control channel conveying a downlink control information (DCI) format, a physical downlink shared channel conveying one or more data transport blocks scheduled by the DCI format, and configuration information for transmission of a physical uplink control channel (PUCCH) conveying acknowledgement information in response to the reception of the one or more data transport blocks; and transmitting the PUCCH in time-frequency resources within a first slot. An index of the first slot is configured by the DCI format. The time-frequency resources within the first slot are configured by the DCI format through a configuration of an index of a first symbol, a number of consecutive slot symbols, and an index of a first frequency resource block.

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： Methods and apparatus are described for transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) bits in a physical uplink shared channel (PUSCH) by a user equipment (UE) in a communication system. A method includes receiving, from a base station, a first configuration of a plurality of cells and a second configuration of at least one offset for HARQ-ACK by higher layer signaling; obtaining HARQ-ACK bits for the plurality of cells, based on an order of cell indexes and a number of transport blocks for each of the plurality of the cells; identifying a number of coded symbols for the obtained HARQ-ACK bits based on a number of the obtained HARQ-ACK bits and an offset for HARQ-ACK corresponding to the obtained HARQ-ACK bits; and transmitting, to the base station, signals for the obtained HARQ-ACK bits on one PUSCH of multiple PUSCHs based on the number of coded symbols.
