    Abstract: A system and a method are disclosed for signaling and scheduling in carrier aggregation with multiple serving cells. In some embodiments, the method includes: receiving, by a User Equipment (UE), in a first Component Carrier (CC), a Downlink Control Information (DCI), the DCI scheduling a first Physical Downlink Shared Channel (PDSCH) in a second CC, and a second PDSCH in a third CC, the second CC and the third CC being different, the DCI including a multi-carrier Time Domain Resource Allocation (TDRA) index; retrieving, based on the multi-carrier TDRA index, from a multi-carrier TDRA table stored by the UE, a TDRA for the first PDSCH and a TDRA for the second PDSCH; and receiving, by the UE, the first PDSCH, using time domain resources for PDSCH reception based on the retrieved TDRA for the first PDSCH.

    Abstract: A method of semi-persistently scheduled (SPS) release, comprising: receiving, by a user equipment (UE), one or more occasions of SPS physical downlink shared channels (PDSCHs) over multiple slots for a transport block (TB) according to an SPS configuration; receiving, by the UE, a physical downlink control channel (PDCCH) including a downlink control information (DCI) format such that an end of a last symbol of the PDCCH is received before or at a same time as an end of a last symbol of a first occasion of a received SPS PDSCH; and releasing, by the UE, the SPS configuration in response to receiving the PDCCH.

    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 device may include a transceiver configured to access a communication network including a primary cell and a secondary cell, and a device controller configured to receive, on the secondary cell, scheduling information for the primary cell, and monitor a common search space for the primary cell. The device controller may be configured to selectively monitor the common search space for broadcast information. The device controller may be configured to selectively monitor the common search space based on a type of the common search space on the primary cell. A method may include scheduling, by a first scheduling mechanism, a primary cell, wherein the first scheduling mechanism comprises scheduling the primary cell by a secondary cell, scheduling, by a second scheduling mechanism, the primary cell, and deactivating the secondary cell based on switching from the first scheduling mechanism to the second scheduling mechanism. The second scheduling mechanism may include self-scheduling.

    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.
