Abstract: A method and a user equipment (UE) are provided for explicitly linking repeated physical downlink control channels (PDCCHs). The UE receives the repeated PDCCHs from a network. Each of the repeated PDCCHs include downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE. The UE links the repeated PDCCHs having common PDCCH candidate numbers across search space (SS) sets of a control resource set (CORESET). The repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission and reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.

Abstract: A method and a user equipment (UE) are provided for resource allocation. The UE receives repeated physical downlink control channels (PDCCHs) from a network. Each of the repeated PDCCHs includes downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE. The UE determines resources for at least one of transmission and reception at the UE, from a PDCCH having a latest start symbol or a latest ending symbol among the repeated PDCCHs. The repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.

Abstract: A method for cross carrier scheduling can include: determining that a candidate DCI for a UE schedules a DG PDSCH that at least partially overlaps an SPS PDSCH for the UE, wherein the DCI is configured to be transmitted on a first CC having a first SCS, and the DG PDSCH is configured for transmission on a second CC having a second SCS different from the first SCS; determining a timing gap based on the smallest of the first SCS and the second SCS; determining that an available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; cancelling the SPS PDSCH responsive to determining that the available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; and transmitting the DCI to the UE.

Abstract: A method and user equipment are provided. The method includes receiving a scheduling of an uplink (UL) signal on a target cell that collides with a UL signal on a source cell; determining a time duration from an ending symbol of a physical downlink control channel (PDCCH) scheduling the UL signal on the target cell; determining that a first symbol of the UL signal on the source cell is after the time duration from the ending symbol of the PDCCH; and dropping at least a portion of the UL signal on the source cell in response to determining that the first symbol of the UL signal on the source cell is after the time duration from the ending symbol of the PDCCH.

Abstract: An apparatus and method are provided for counting a number of uplink and/or downlink channels per slot for a UE capability in order to determine a maximum number of channels a UE is capable of processing per slot. A UE counts all PDSCHs or PUSCHs that the UE is scheduled or configured to receive or transmit, respectively, except for exception 1, exception 2, or exception 3, wherein a beginning of the symbol j is at least N_2 symbols after an end of the symbol i, the SPS PDSCH is not counted, and generates UE capability information based on the counted number of the PDSCH or PUSCH per slot.

Abstract: A method for processing multiple overlapping channels includes: transmitting, by a base station comprising a processor and a memory, a channel comprising a plurality of physical downlink shared channels (PDSCH) in a slot, the PDSCHs being organized into one or more sub-groups of overlapping PDSCHs; and receiving, by the base station and from a mobile station, an acknowledgment (ACK) or a negative acknowledgment (NACK) for two or more overlapping PDSCHs in at least one of the one or more sub-groups in the slot.

Abstract: A device, such as a UE, and a Transmit and Receive Point (TRP) in a High-Speed Train-Single Frequency Network (HST-SFN) are disclosed that provide network-assisted frequency-offset compensation for the device. The device includes a receiver that receives a first reference signal and a second reference signal sent over a wireless network from a first TRP. The first reference signal corresponds to a QCL RS of the second reference signal. The device receiver determines delay-spread and average-delay information for a path between the first TRP to the device based on the first reference signal. The device receiver further receives a third reference signal from a second TRP that includes Doppler-shift and Doppler-spread information, and corresponds to a QCL RS of a fourth reference signal transmitted from the second TRP or corresponds to the second reference signal transmitted in a SFN manner from the first TRP.
