Abstract: Apparatuses, systems, and methods for radio resource management (RRM) signal reception. A user equipment device (UE) may receive, via a first reception path, an RRM related signal and receive, via a second reception path, a non-RRM related signal that may be multiplexed with the RRM related signal onto a symbol. The first reception path may be a first antenna port of an antenna panel or a first antenna panel of the UE and the second reception path may be a second antenna port of the antenna panel or a second antenna panel of the UE. The RRM related signal may include a reference signal for RRM. and may be included in a non-zero power (NZP) interference measurement.

Abstract: A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Abstract: A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.

Abstract: Embodiments are disclosed for capability reporting for antenna switching, AS, sound reference signals, SRS. A user equipment (UE) can transmit a capability report for AS SRS that includes a plurality of receive antenna (e.g., six or eight receive antenna), and receive SRS instructions based on the capability report. The UE can transmit a first temporary capability reduction for a duration, and transmit a first SRS according to the first temporary capability reduction and the SRS instructions, while maintaining phase continuity. To maintain phase continuity, the UE can calibrate one or more SRS ports participating in the AS SRS to transmit with substantially a same transmit power. The UE can determine that a second SRS overlaps an other transmission in a time domain, determine that the other transmission has an absolute priority over the second SRS, and transmit the other transmission but not the second SRS.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for UE positioning. In an example, a UE transmits a sounding reference signal for positioning (SRSp) to a base station. The SRSp transmission can use frequency hopping and can rely on a window and/or a collision rule associated with the entire frequency hopping sequence or only a frequency hop of such a sequence. The window and/or collision rule can reduce the potential for signal collision with non-SRSp signals. Further, the UE can implement a low power high accuracy position (LPHAP) technique. In this technique, a fallback behavior or an SRSp transmission can be stopped if the UE is not able to accurately measure “N” configured reference signals, where “N” can be based on the positioning method.

Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for supporting channel state information (CSI) report configuration for network spatial elements adaptation. The UE can receive a CSI report configuration from the base station indicating a first configuration to configure a first CSI report, and a second configuration to configure a second CSI report. The UE can determine one or more active configurations selected from the first configuration and the second configuration, based on whether one or more of the first configuration or the second configuration is activated by a Medium Access Control (MAC) Control Element (MAC CE) or triggered by a Downlink Control Information (DCI). The processor can be further configured to select, based on a report mode, one or more CSI reports from the first CSI report and the second CSI report. The report mode can be a basic mode or an enhanced mode.
