Abstract: A user equipment, a base station, and a method for managing scheduling offsets. The UE is configured to receive a configuration for a set of minimum scheduling offset values for a first cell and receive a physical downlink control channel (PDCCH) of a second cell that is same as or different than the first cell. The UE is also configured to decode a downlink control information (DCI) format that includes a field that indicates a minimum scheduling offset value applicable for a reception of a physical downlink shared channel (PDSCH) on an active DL BWP of the first cell, or for a transmission of a physical uplink shared channel (PUSCH) on an active UL BWP of the first cell. The UE is also configured to determine a delay and apply the minimum scheduling offset value in a second slot of the second cell that is separated from the first slot by the delay.

Abstract: Methods and apparatus for physical downlink control channel (PDCCH) reliability enhancements. A method includes receiving first information for a number of N>1 search space sets. For each of the N search space sets, the first information includes: an index, wherein search space sets are indexed in an ascending order of respective indexes, a periodicity, wherein the periodicity is same for all of the N search space sets, and an indication that the N search space sets are linked for receptions of PDCCHs, wherein the PDCCHs provide identical information. The method further includes determining a number of N PDCCH reception occasions in M≥1 slots within a period according to the periodicity. A n-th PDCCH reception occasion from the NPDCCH reception occasions is according to a n-th search space set from the N search space sets. The method further includes receiving N PDCCHs in the N PDCCH reception occasions.

Abstract: Methods and apparatuses for uplink (UL) channel sounding between bandwidth parts (BWPs). A method for operating a user equipment (UE) includes receiving first information for a set of UL BWPs of a serving cell, wherein the set of UL BWPs includes more than one UL BWP and receiving second information, for each UL BWP from the set of UL BWPs, for sounding reference signal (SRS) resource sets. The method further includes determining, for each UL BWP from the set of UL BWPs, corresponding first SRS resources from the SRS resource sets and transmitting a SRS, in each UL BWP from the set of UL BWPs, using the corresponding first SRS resources.

Abstract: Methods and apparatus for physical downlink data channel (PDCCH) and reference signal (RS) based paging in a wireless communication system. A method includes receiving: a first configuration for a search space set in common search space (CSS), wherein the search space set is for a downlink control information (DCI) format that includes a tracking RS (TRS) availability indication field, wherein the TRS availability indication field in the DCI format provides a bitmap; and a second configuration for a number of TRS resources sets. The method further includes determining a TRS resources set from the number of TRS resources sets associated with a bit from the bitmap, wherein TRS resources from the TRS resources set are present for a time duration based on an associated bit for the TRS resources set in the bitmap; and receiving TRS resources from the number of TRS resources sets that are present.

Abstract: Methods and apparatuses for reduced physical downlink control channel (PDCCH) monitoring in a wireless communication system. A method for operating a user equipment includes receiving a configuration for one or more search space sets. The one or more search space sets provide parameters for one or more candidate PDCCH receptions. The method includes determining a first number of candidate PDCCH receptions for a first number of more than one consecutive slots. A candidate PDCCH reception is over a number of control channel elements (CCEs). The first number of candidate PDCCH receptions over a corresponding number of CCEs does not exceed a capability corresponding to the first number of more than one consecutive slots for a maximum number of candidate PDCCH receptions over a corresponding maximum number of non-overlapped CCEs. The method further includes receiving the first number of candidate PDCCH receptions.

Abstract: Methods and apparatuses for multi-cell scheduling with reduced control overhead. A method for receiving physical downlink control channels (PDCCHs) includes receiving information for a first group of N1 cells and for a second group of N2 cells, determining a total number of PDCCH receptions in a slot on a scheduling cell based on N1 and on a ratio of N2 over M, and receiving a number of PDCCHs in the slot on the scheduling cell that is not larger than the total number. A PDCCH provides a downlink control information (DCI) format. The DCI format schedules one of: a physical downlink shared channel (PDSCH) reception, or a physical uplink shared channel (PUSCH) transmission, on one cell from the first group of N1 cells, or PDSCH receptions, or PUSCH transmissions, on a number of cells up to a maximum of M cells from the second group of N2 cells.
