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: Technology is provided for supporting different numerologies for concurrent intra-frequency measurements and downlink data reception. A user equipment (UE) may send a message to the a wireless network to indicate whether the UE supports a mixed numerology wherein a different subcarrier spacing (SCS) is used in a serving cell or a neighboring cell for concurrent processing of at least two of: intra-frequency measurement by the UE of a synchronization signal block (SSB); intra-frequency measurement by the UE of a channel state information reference signal (CSI-RS) for mobility; and reception by the UE of a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH). Based on the indication, the network may configure at least one of a CSI-RS measurement expectation, an SSB measurement expectation, and a scheduling restriction for reception of the PDCCH or the PDSCH by the UE.

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.

Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

Abstract: Switching schemes at a mobile device may include, in response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with a high speed train (HST), decoding a communication received from a network. The communication may include a first radio resource control (RRC) information element (IE) having an HST configuration associated with an HST scheme. The HST configuration may be applied to thereby operate using the HST scheme. In response to being out of range of the plurality of TRPs associated with the HST, a communication received from the network may be decoded. The communication may include a second RRC IE having a non-HST configuration associated with a non-HST scheme. The non-HST configuration may be applied to thereby operate using the non-HST scheme.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced direct secondary cell activation in a 5G wireless communications system. A user equipment (UE) can receive a Radio Resource Control (RRC) command from a 5G Node B (gNB) via a Primary Cell (PCell) or via a Primary Secondary Cell (PSCell) that includes configuration data for a Secondary Cell (SCell), where the SCell operates in Frequency Range 2 (FR2). The RRC command includes a first Transmission Configuration Indicator (TCI) state for the SCell, and the UE can activate the SCell for the UE based at least on the configuration data, concurrently with the first TCI state for receiving the PDCCH transmission. The UE can receive a Physical Downlink Control Channel (PDCCH) transmission via a first antenna beam from the SCell, where the first antenna beam is based on the first TCI state.
