Abstract: A user equipment (UE) and a network node can support sounding reference signals (SRS) based antenna beam pair selection for simultaneous uplink transmission with multi-panels by the UE. One or more antenna beam pairs of a UE having a first antenna panel and a second antenna panel may be used to transmit SRSs to a first transmission reception point (TRP) and a second TRP simultaneously using SRS resources configured by one or more SRS configuration sets from the network node. The UE can configure a SRS spatial filter for a SRS resource to indicate a direction of an antenna beam, while some of the SRS resource is configured by the one or more SRS configuration sets received from the network node. The network node can select an antenna beam pair among the one or more antenna beam pairs based on indications of signal strength of SRSs received.

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: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for a network to use Doppler shift pre-compensation values for communicating Tracking Reference Signal (TRS) to a user equipment (UE) and for implementing mechanisms for triggering the UE to measure the Doppler shift pre-compensated TRS. Some aspects of this disclosure relate to a base station including a processor that determines a Doppler shift pre-compensation value associated with the UE in response to determining that the UE is moving with a speed greater than a threshold. The processor further generates an aperiodic Tracking Reference Signal (AP-TRS) or a semi persistent TRS (SP-TRS) for the UE. The AP-TRS or the SP-TRS is decoupled from a periodic TRS (P-TRS). The processor further transmits the AP-TRS or the SP-TRS to the UE. The AP-TRS or the SP-TRS can be used for time and frequency synchronization.

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 (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE receives a configuration for a physical downlink control channel (PDCCH) including repetitions for PDCCH candidates comprising first PDCCH data, wherein the PDCCH candidates are repeated across multiple durations of a DL resource grid, detects, based on a repetition detection scheme, each of the PDCCH candidates and combines soft bits from each of the PDCCH candidates, wherein the combined soft bits are jointly decoded to determine the first PDCCH data and calculates a number of blind decodes (BDs) for the durations of the DL resource grid carrying the PDCCH candidates, wherein at least one BD value for the PDCCH candidates is scaled by a scaling factor for the calculation of the number of BDs.

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.

Abstract: Some aspects relate to apparatuses and methods for a wireless system supporting two timing advances in a serving cell for a user equipment (UE) communicating with two different transmission reception points (TRPs). The UE can determine that a first timing advance (TA) group (TAG) and a second TAG are configured for a serving cell based on a configuration received from the base station; and further determine a first TA adjustment value based on a first timing advance command (TAC) and a second TA adjustment value based on a second TAC. The UE can select a TAC from the first TAC or the second TAC to be applied to an uplink transmission. The UE can further select, based the selected TAC, a TAG from the first TAG or the second TAG; and transmit the uplink transmission according to the selected TAC with the selected TAG.
