Abstract: Systems and methods of transmitting and receiving combined uplink control information (UCI) in respect of downlink assignments are provided. The UE is configured to combine certain UCI based on a property of downlink assignment, such as PDCCH ID, beam information, CORESET. The UE may also be configured to determine which UCI having the same value of the property of downlink assignment to combine. This can be based on a value-specific monitoring window or a monitoring window that is common to multiple values of the assignment property.

Abstract: According to one aspect of the present disclosure, a method for uplink synchronization is provided, wherein the method includes receiving, by a user equipment (UE), a radio resource control (RRC) message from a network, the RRC message comprising a first Timing Advance Group (TAG) identity (ID) and a second TAG ID different than the first TAG ID. The method also includes transmitting, by the UE, a first signal over a component carrier in accordance with a timing advance associated with the first TAG ID and a second signal over the component carrier in accordance with a timing advance associated with the second TAG ID.

Abstract: A method for reference signal processing is provided. In this example, the method includes receiving, by a UE, a message from a network device, where the message indicates both that a first reference signal is to be transmitted over a first resource and that a second reference signal is to be transmitted over a second resource. The method also includes receiving, by the UE, at least the first reference signal in accordance with capabilities of the UE and the message received from the network device.

Abstract: Networks use channel state information reference signals (CSI-RSs) to measure channel conditions between a user equipment (UE) and a transmit/receive point (TRP) in a cell. The resources configured for the transmission of a CSI-RS may be indicated to the UE using higher layer signaling. Measurement results for a CSI-RS are transmitted by the UE in the form of a measurement report. A need exists for signaling designs that aim to provide more flexible and efficient signaling of CSI-RS resource configurations and measurement reports. In some embodiments, CSI-RS resource configurations and measurement reports are resource-specific. The CSI-RS resource configurations may be independent from an identifier of the cell that the CSI-RS is transmitted from, and the measurement reports do not necessarily include the identifier of the cell. Advantages may include allowing the network to freely allocate CSI-RS resources without the need for reconfiguration at the UE side.

Abstract: Methods and apparatus are provided that provide single or multiple Physical Downlink Control Channel (PDCCH) messages for single or multiple Physical Downlink Shared Channel (PDSCH) messages to support network coordination schemes such as Non-Coherent Joint Transmission.
