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: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.

Abstract: A base station is configured to receive channel state information (CSI) from a user equipment (UE). The base station transmits configuration information including one or more interference measurement resources (IMRs) allocated for measurement by the UE, receives a reference CSI report from the UE, receives a new CSI report including interference and noise power fluctuation feedback from the UE and selects a modulation and coding scheme (MCS) for the UE based on at least the interference and noise power fluctuation feedback and the reference CSI report.

Abstract: Techniques are provided for implementing power control in a 2-step random access channel (RACH) procedure, including implementing power control during MsgA transmission of the 2-step RACH procedure. For example, a user equipment (UE) determines a transmission power for a physical uplink shared channel (PUSCH) transmission based on a transmission power of a physical random access channel (PRACH) preamble that is associated with the PUSCH transmission during the 2-step RACH procedure. The UE further performs the 2-step RACH procedure using the determined transmission power of the PUSCH to establish a connection to the wireless network.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for power control aspects for MsgA physical uplink shared channel (PUSCH). The approach includes determining a transmission power for a PUSCH associated with a physical random access channel (PRACH) in a 2-step random access channel (RACH) mode, where the transmission power for the PUSCH is determined based on a transmission power of the associated PRACH and a power offset. The approach further includes ramping up a transmission power of the PRACH and PUSCH until a maximum transmission power is reached.

Abstract: Some embodiments include a system, method, and computer program product for managing beam switching at a higher subcarrier spacing (SCS) at millimeter wavelength (mmWave) frequencies in a 5G wireless communications system. A user equipment (UE) transmits a beam switching gap (BSG) capability to a 5G Node B (gNB). The UE receives a transmission configuration indicator (TCI) state from the gNB, and performs a beam switch to the TCI state corresponding to a first beam. The UE can receive a first control resource set (CORESET) on the first beam and a second CORESET on a second beam where the BSG occurs between the first CORESET and a second CORESET. The UE can perform beam switching within the BSG from the first beam to a second beam, and receive the second CORESET on the second beam. The UE can determine and transmit modified candidate values of beam switching parameters to the gNB.
