Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: Embodiments of the present disclosure relate to Physical Uplink Control Channel (PUCCH) reliability enhancement. According to embodiments of the present disclosure, a processor of a UE receives, from a BS associated with a first TRP and a second TRP, a first message for configuring a PUCCH resource to be used by the UE to perform a PUCCH transmission with the BS. In this case, the first message indicates a first configuration corresponding to the first TRP and the first configuration comprises at least one power control parameter associated with the first TRP. The message further indicates a second configuration corresponding to the second TRP and the second configuration comprises at least one power control parameter associated with the second TRP. The processor performs the PUCCH transmission with the BS via the first and second TRPs based on the first message. In this way, the reliability and robustness of the PUCCH transmission for multiple TRP is enhanced.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for a network to use Doppler shift pre-compensation values for communicating Tracking Reference Signal (TRS) to a user equipment (UE) and for implementing mechanisms for triggering the UE to measure the Doppler shift pre-compensated TRS. Some aspects of this disclosure relate to a base station including a processor that determines a Doppler shift pre-compensation value associated with the UE in response to determining that the UE is moving with a speed greater than a threshold. The processor further generates an aperiodic Tracking Reference Signal (AP-TRS) or a semi persistent TRS (SP-TRS) for the UE. The AP-TRS or the SP-TRS is decoupled from a periodic TRS (P-TRS). The processor further transmits the AP-TRS or the SP-TRS to the UE. The AP-TRS or the SP-TRS can be used for time and frequency synchronization.

Abstract: Described are processing time approaches to simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In various approaches, simultaneously scheduling a plurality of physical downlink shared channels (PDSCH) through a single DCI transmitted via a physical downlink control channel (PDCCH) occurs, wherein each of the plurality of PDSCHs is associated with a respective cell in a plurality of cells. The approaches further include transmitting data to or receiving data to a user equipment (UE) based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH. In other aspects, a hybrid automatic repeat request-acknowledgement (HARQ-ACK) is received via a physical uplink control channel (PUCCH), the HARQ-ACK having been sent by a user equipment (UE) in response to one of the plurality of PDSCHs, wherein the HARQ-ACK is sent no earlier than a time offset following a reference time in one of the plurality of PDSCHs. In other aspects, transmitting data to or receiving data to a user equipment (UE) is based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH, the time offset being configured to permit analog beam switching by a user equipment (UE).
