Abstract: Systems and methods are provided for a user equipment (UE) to perform frequency offset (FO) delta tracking. For an anchor component carrier (CC), the UE wakes up to perform tracking updates on a plurality of successive DRX cycles. For the non-anchor CC, the UE determines a minimum update interval Δtupd, and schedules wake-ups on a first subset of the plurality of successive DRX cycles based on the minimum update interval Δtupd. For the first subset of the plurality of successive DRX cycles with scheduled wake-ups, the UE performs the tracking updates on the non-anchor CC and updates an FO delta between the anchor CC and the non-anchor CC. For a second subset of the plurality of successive DRX cycles without the scheduled wake-ups on the non-anchor CC, the UE applies the FO delta to correct for a frequency error.

Abstract: A base station of a network provides a user equipment (UE) with information relating to monitoring a Physical Downlink Control Channel (PDCCH) of multiple component carrier (CCs) in a carrier aggregation (CA) scheme. The base station configures a first CC and a second CC of a CA combination for a user equipment (UE) and provides the UE with information for the CA combination, wherein the information comprises an indication whether the first CC and the second CC are collocated.

Abstract: A system is configured for reconfiguration of a Synchronization Signal Block (SSB) pattern. The system is configured for obtaining data including a configuration for a Synchronization Signal Block (SSB) transmission carrying a physical broadcast channel (PBCH), the configuration specifying, for an SSB of the configuration, resource elements (REs) allocated for transmitting a primary synchronization signal (PSS) to a user equipment (UE) and REs allocated for transmitting a secondary synchronization signal (SSS) to the UE. The system is configured for selecting a set of REs that are unused in the configuration for the SSB transmission, specifying a filling sequence for extending a synchronization signal or an SSB to the set of REs that are unused in the configuration of the SSB transmission, generating data including an enhanced configuration for the SSB transmission that includes the extended synchronization signal or the extended SSBs, and transmitting the SSB transmission using the enhanced configuration.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: determining time or frequency synchronization information for each of one or more candidate synchronization signal blocks (SSBs) for a secondary cell (SCell) before receipt of a transmission configuration indication (TCI) state activation command or a SCell activation command, receiving the TCI state activation command, and based on the received TCI state activation command, receiving at least one signal from the SCell using the determined time or frequency synchronization information for one of the one or more candidate SSBs.

Abstract: The present application relates to scheduling SSB measurements on SSB beams. In an example, a base station can transmit SSBs on SSB beams that form a serving cell. Depending on an SSB measurement on one of the SSB beams, a UE can schedule an additional SSB measurement on this SSB beam only or schedule SSB measurements on the different SSB beams.

Abstract: Apparatuses, systems, and methods to enhance system performance (e.g., UL throughput) without impinging on (e.g., tightening) processing timeline for UL-SCH data and/or CSI reporting. A base station may request for a UE to send a CSI report(s) during PDCCH monitoring. The base station may also request the UE to send UL-SCH data. At a first transmit opportunity, the UE may transmit first PUSCH (including UL-SCH data that may be multiplexed onto the first PUSCH). Additionally, at a second (later) transmit opportunity, the UE may transmit second PUSCH (including the CSI report(s) that may be multiplexed onto the second PUSCH). The second transmit opportunity may be identified as a transmit opportunity starting at least a specified number of symbols after a first symbol of the first repetition. The specified number of symbols may be dependent upon at least one of UE uplink processing time capabilities or SCS.

Abstract: The present application relates to a paging mechanism. In an example, a network can transmit SSBs periodically on multiple SSB beams. A UE can receive, during a DRX cycle, an SSB per detected SSB beam and perform SSB-based measurements. Based on these measurements, the UE can perform PDCCH monitoring and PDSCH decoding on at least two beams. The PDCCH monitoring can indicate a scheduled paging message from the network. The PDSCH decoding can allow the UE to determine the paging message.

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.
