Abstract: Systems and methods for networks having user equipment (UE) that can perform measurement/reporting of received signals and a sounding reference signal (SRS) transmission that is part of an SRS antenna port switching procedure are described herein. In some circumstances, the measurement and the SRS antenna port switching procedure overlap on one or more symbols. Across various embodiments, the UE prioritizes one of the measurement and the SRS antenna port switching procedure based on one or more of a scheduling type (periodic, semi-persistent, aperiodic) of the measurement, a scheduling type of a channel state information (CSI) report for a measurement result for the measurement, and/or a scheduling type of the SRS transmission of the SRS antenna port switching procedure. Networks that avoid overlaps by scheduling SRS transmissions away from UE signal measurements, or transmissions of signals to be measured away from UE SRS antenna port switching procedures, are also described.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a physical uplink control channel (PUCCH) secondary cell (SCell) activation command from a primary cell (PCell) or primary secondary-cell-group cell (PSCell). The PUCCH SCell activation command is used for an PUCCH SCell activation of a target PUCCH SCell for the UE. The UE performs PUCCH SCell activation operations associated with a valid timing advance (TA) and the PUCCH SCell activation command. TA is considered to be a valid TA when the TA meets a preset criterion. The UE generates a channel state information (CSI) report for transmission to at least one of the PCell, PSCell and the target PUCCH SCell. The CSI report indicates that the PUCCH SCell activation is completed.

Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.

Abstract: Techniques described herein include solutions for utilizing dual port synchronization signal block (SSB) transmissions for multiple receive (Rx) beam selection. In some aspects, a base station transmits a first SSB with a first polarization on a first antenna port, and transmits a second SSB with a second polarization on a second antenna port. The first and second SSBs may be transmitted, for example, using a first transmission reception point (TRP). A user equipment (UE) receives the first and second SSBs, and identifies one or more optimal Rx beams for multiple-input multiple-output (MIMO) communication based on the first and second SSBs.

Abstract: Triggering an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration for transmission to the UE may be encoded. The RRC UL gap configuration may include configuration information associated with at least one of a periodicity, offset, or length. Measurement information received from the UE may be decoded. The measurement information may include at least one of a power headroom value, a PCMAX,f,c value, or a P value. Based on the power headroom value, the PCMAX,f,c value, or the P value, the UL gap configuration may be activated by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.

Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform cell reselection. In an example, timing requirements for synchronization signal processing are defined based on a beam sweeping capability of the device. Synchronization signals are received and processed according to the timing requirements to complete a cell reselection procedure. In another example, location data of the device is used to look up a database of cell identifiers. A cell identifier is determined based on the look-up and a cell reselection procedure is performed using the cell identifier.
