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: Some aspects relate to a carrier aggregation wireless system having a user equipment (UE). The UE can generate a report of a UE capability to support a first downlink control information (DCI) in a first DCI format for a cell of a plurality of cells of the wireless system and a second DCI in a second DCI format for the cell, and a report of a UE capability to support splitting a blind decoding (BD) of control channel element (CCE) (BD/CCE) budget between performing BD/CCE carrying the first DCI in the first DCI format, and performing BD/CCE carrying the second DCI in the second DCI format. The first DCI in the first DCI format can schedule data transmissions for a set of multiple cells. The UE may perform BD/CCE carrying the first DCI in the first DCI format, and perform BD/CCE carrying the second DCI in the second DCI format.

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: A user equipment (UE) is configured to report beam information for a secondary cell. The UE receives a signal from a network indicating that a physical uplink control channel (PUCCH) secondary cell (SCell) activation procedure has been initiated, collects beam information corresponding to a target PUCCH SCell, reports the beam information to the network, determines that the target PUCCH SCell has been activated as a PUCCH SCell and transmits uplink control information (UCI) over a PUCCH to the PUCCH SCell, wherein the UE is also configured with a different PUCCH corresponding to a primary cell (PCell).

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: A base station configures a physical uplink control channel (PUCCH) for a user equipment (UE) operating in a frequency band above 52.6 GHz. The base station allocates a predetermined number of resource blocks (RBs) for a physical uplink control channel (PUCCH) transmission, wherein the predetermined number of RBs is greater than one RB, transmits a PUCCH configuration including the predetermined number of RBs to the UE and receives a PUCCH transmission based on the PUCCH configuration and including a data sequence and a DMRS sequence, wherein the PUCCH configuration results in a multiplexing of a plurality of UEs based on a plurality of demodulated reference signal (DMRS) sequences.
