Abstract: Techniques for supporting positioning for mobile UEs in reduced-power states are described, such as for low power high accuracy positioning (LPHAP). In many embodiments, uplink (UL) and/or UL+downlink (DL) positioning for UEs in inactive and/or idle states are enabled in a manner that improves positioning services in 5G networks by reducing the need to transition into higher power states. For example, positioning configuration groups may be utilized to enable a common positioning configuration, or portions thereof, to be utilized in multiple network cells. In various embodiments, a power metric of signals may be utilized to determine network cells in a positioning configuration group. In another example, various techniques are utilized to obtain, validate, or update positioning configurations and/or activate positioning transmissions at a UE with the UE in an inactive or idle state.

Abstract: Mobile devices (UEs) may use Inter-UE Control (IUC) sidelink (SL) communications for SL positioning reference signal (SL-PRS) resource allocation procedures without relying on a network/base station/cell. A transmitting UE may receive, e.g., from an assisting UE, an indication identifying preferred SL-PRS resources for the transmitting UE to consider and/or non-preferred SL-PRS resources for the transmitting UE to avoid. The indication may be received in response to an IUC triggering condition or in response to a request previously transmitted by the transmitting UE to the assisting UE. Alternatively, the transmitting UE may first attempt to reserve specified SL-PRS resources by transmitting, to an assisting UE, a reservation request identifying the specified SL-PRS resources. The transmitting UE may receive, in response, information about SL-PRS resource reservation collisions involving the specified SL-PRS resources.

Abstract: The present application relates to devices and components including apparatus, systems, and methods that support multi-cell scheduling. In an example, a base station sends a downlink control information (DCI) having a particular DCI format to a user equipment (UE). The DCI can indicate cells that are co-scheduled and can indicate a value for an index usable by the UE to determine a set of DMRS antenna port number to use for at least one cell of the co-scheduled cells. Depending on how the UE is configured for the at least one cell (e.g., depending on a configured DMRS antenna port indication table), the UE can use the value or a different value to determine the set of DMRS antenna port numbers.

Abstract: A wireless communication system may use resource and report configuration enhancements for Type 2 network spatial elements adaptation. In some embodiments, the network node may configure a first CSI resource setting and at least a second CSI resource setting for channel measurement. The first CSI resource setting and the second CSI resource setting link to one CSI reporting setting. The second CSI resource setting may comprise different spatial relation information or a different antenna port than the first resource setting.

Abstract: Systems and methods related to user equipment (UE) behavior under cell discontinuous transmission (DTX)/discontinuous reception (DRX) mechanisms are disclosed herein. A UE may receive configuration information for a cell DTX/DRX pattern used by a serving cell that includes a periodicity, an offset, an active duration length of/for the cell DTX/DRX pattern, and/or UE behavior information defining one or more UE behaviors for a non-active serving cell mode. The UE may then identify a non-active duration of the cell DTX/DRX pattern during which the serving cell is in a non-active state. Finally, the UE may perform communication with the network on the first serving cell according to the non-active serving cell mode during the non-active duration of the first cell DTX/DRX pattern. Details for embodiments where the UE is further configured to use a UE connected mode DRX (CDRX) mechanism are also provided. Corresponding base station behaviors are also described.

Abstract: Techniques discussed herein may better ensure proper timing and synchronization of transmissions within a wireless communications network that includes a terrestrial network and a non-terrestrial network (NTN). A user equipment (UE) may maintain (e.g., determine and update on an ongoing basis) a timing advance (TA) value that the UE may apply to uplink (UL) transmissions to account for propagation delays, including changes in propagation delays, between the UE, NTN, and terrestrial network. TA maintenance may be based on network broadcasts, random access channel (RACH) procedures, control messages, timing drift rates (e.g., of the UE or NTN satellite), beam switching, and more.

Abstract: A wireless communication system may use multiple power control offsets for a CSI-Reference signal (RS) resource. A network node may provide a user equipment (UE) with a Channel State Information (CSI) report configuration information element.

The UE may provide a CSI report with CSI measurements corresponding to one or more of the power control offsets.

Abstract: Apparatus and methods are provided for selectively using multiple codewords for uplink (UL) multiple-input multiple-output (MIMO) communication. A user equipment (UE) is configured to use at least one of a first codeword and a second codeword for UL communication with a base station. The UE determines whether to enable or disable the second codeword for a physical uplink shared channel (PUSCH) transmission. In response to determining to disable the second codeword, the UE transmits the PUSCH transmission including the first codeword to the base station. In response to determining to enable the second codeword, the UE transmits the PUSCH transmission including the first codeword and the second codeword to the base station.

Abstract: A user equipment (UE) includes a set of transceivers and a processor. In some examples, the UE may receive an uplink (UL) switching indication that indicates UL transmission switching on one antenna port. In some examples, the UE may transmit a first UE capability. The first UE capability may indicate support to switch a transmit chain to an associated band. In some examples, the UE may transmit a second UE capability. The second UE capability may indicate support to transmit on an unchanged transmit chain during an UL switching period for a switching transmit chain. The UE may also be triggered for a first UL transmission switch from one of a first band on a first transmit chain or a second band on a second transmit chain to a third band. Additionally, the UE may switch the first band or the second band to the third band.
