Systems, methods, and instrumentalities are described for handling positioning reference signals in a wireless communication system. The positioning reference signals may be assigned priorities that may be used to facilitate various operations of a wireless transmit/receive unit (WTRU) such as positioning related services, collision avoidance, measurement and reporting, etc. The WTRU may be configured with multiple muting patterns associated with the positioning reference signals and may switch between different muting patterns based on the priorities of the positioning reference signals and/or other downlink (DL) or uplink (UL) transmissions that may overlap or collide with the positioning reference signals.

Handling positioning reference signals in wireless systems

A method for a Wireless Transmit/Receive Unit (WTRU). The method including receiving from a network configuration information indicating multiple frequency layers for positioning reference signals; and at least one activated frequency layer from among the multiple frequency layers. The frequency layers may be associated with one or more carriers for data transmission, wherein the carrier is co-located with its associated frequency layer for positioning; and bandwidth parts (BWPs) within carriers for data transmission. The WTRU may receive from the network activation/deactivation information indicating activation/deactivation of any of a secondary cell (SCell) and a BWP. The WTRU may transmit information indicating, for example, a set of frequency layers used for positioning, wherein the set of frequency layers is enabled according to any of an accuracy requirement, a latency, a measured RSRP of one frequency layer, and a measured CSI-RS corresponding to BWPs being a threshold.

Methods and apparatus for enabling frequency layers for positioning

Method, apparatus, and systems for determining and transmitting positioning information in a wireless communication network are provided. For example, a method for wireless communications comprises receiving configuration information related to a set of positioning configurations and a small data transmission (SDT), determining, based on the configuration information, that at least one positioning configuration of the set of positioning configurations satisfies a positioning requirement and is associated with a payload size being less than a data volume threshold (DVT) associated with the SDT, selecting, from the at least one positioning configuration, a positioning configuration associated with a payload size being closest to the DVT, performing a positioning measurement based on the selected positioning configuration, and sending, using an uplink resource for the SDT, a measurement report based on the selected positioning configuration and the positioning measurement.

Methods and apparatus for power-efficient positioning in wireless communication systems

Methods and apparatus are described herein for improved efficiency of a wireless transmit/receive unit (WTRU) transmitting transport blocks (TBs). A WTRU may receive configuration information including uplink resources associated with one or more repetition bundles and a target number of retransmissions for a transport block (TB) associated with at least one hybrid automatic repeat request (HARQ) process. Then, the WTRU may transmit a first TB using a first uplink resource in a first repetition bundle based on the configuration information. Further, the WTRU may increment a retransmission counter. On a condition that the retransmission counter is less than the target number of retransmissions, the WTRU may determine a second uplink resource. Further, the WTRU may retransmit the first TB in the determined second uplink resource. Also, the WTRU may further increment the retransmission counter. Moreover, the first, second and third uplink resources may be physical uplink shared channel (PUSCH) resources.
