    Abstract: A base station of a network configures a first search space having a first search space identification (SearchSpaceId) in a special cell (SpCell) and a second search space having a second search space identification (SearchSpaceId) in a secondary cell (SCell) for monitoring control signaling that schedules operations on the SpCell. The base station transmits a radio resource control (RRC) configuration to a user equipment (UE) including the first SSID and the second SSID, wherein the RRC configuration configures the UE to monitor the first search space having the first SSID for scheduling of a first type of control signaling and the second search space having the second SSID for scheduling of a second type of control signaling.

    Abstract: Methods and apparatuses are disclosed for configuring full power transmission modes in a UE. The disclosed full power transmission modes include a Mode 0 and a Mode 3, which are enhancements over previous modes disclosed in the 3GPP specification. The UE gathers supported modes and configuration capabilities, such as number of ports and supported coherency schemes, and forwards the configuration capabilities to the network. The network analyzes the received information and selects a supported full power transmission mode based on the UE capabilities. The selection is then transmitted to the UE in a PUSCH-Config message. The UE extracts the selection from the PUSCH-Config message, and configures its radio accordingly.

    Abstract: Some embodiments include an apparatus, method, and computer program product for tracking reference signal (TRS) support of high speed use cases of 5G communications in a single frequency network (SFN), where a user equipment (UE) can measure a Doppler offset of a combined signal from two or more transmission reception points (TRPs) of the 5G communications system. A 5G node B (gNB) node can transmit a periodic, semi-persistent (SP), or aperiodic TRS with high measurement density that the UE uses to measure a Doppler offset of a combined signal. For example, the gNB can: trigger the aperiodic TRS based on a downlink assignment; and/or use lower layer signaling to arrange to transmit a semi-persistent TRS or a periodic TRS with a reduced periodicity. In some embodiments, the gNB can measure the Doppler offset based on an uplink signal, and transmit a TRS based on a pre-compensated Doppler frequency.
