    Abstract: A system and a method are disclosed for determining a quasi co-located (QCL) source reference signal (RS) to receive a target signal or channel. The method includes receiving antenna indicator information indicating one or more first antenna configurations and one or more second antenna configurations from a base station; identifying a first set of symbols at which the one or more first antenna configurations are applied and a second set of symbols at which the one or more second antenna configurations are applied; and receiving the target signal or channel using a version of the QCL source RS at a time instance based on whether the time instance occurs in the first set of symbols or the second set of symbols.

    Abstract: A method for PUSCH repetition or PRACH aggregation. In some embodiments, the method includes transmitting, by a User Equipment (UE), in a first slot, a first Physical Uplink Shared Channel (PUSCH) transmission including a set of coded bits selected from a circular buffer of the UE based on a first redundancy version (RV); determining, by the UE, that a second slot is available for an earliest repetition of the first PUSCH transmission, the second slot being later than the slot immediately following the first slot; determining, by the UE, based on the second slot, a second redundancy version; and transmitting, by the UE, in the second slot, a second PUSCH transmission including a set of coded bits selected from the circular buffer of the UE based on the second redundancy version, the second PUSCH transmission being a repetition of the first PUSCH transmission.

    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.
