Abstract: Systems and methods for measuring at and reporting by a target user equipment (UE) of one or more positioning signals sent from one or more assisting UEs to the target UE are disclosed herein. The target UE may receive a positioning signal from an assisting UE according to a communication received at the target UE. The target UE may proceed to perform a positioning measurement using the positioning signal received from the target UE. The positioning measurement may be used by the target UE to estimate its own position, or the positioning measurement may be sent to another entity within a wireless communications system to be used in estimating the physical position of the UE. The handling of multiple received positioning signals from various sources, and the handling of situations where, for example, a transmission reception point (TRP) and an assisting UE may schedule overlapping positioning signals, ate also discussed.

Abstract: A method for bandwidth part (BWP) switching includes receiving an indication to switch operation of a user equipment (UE) configured for dual connectivity from a first BWP to a second BWP. At least one of an allowed interruption duration or an allowed BWP switch delay are determined for switching operation of the UE from the first BWP to the second BWP, where the allowed interruption duration is up to two subframes, and where the allowed BWP switch delay is at least one slot greater than two subframes. Operation of the UE is switched from the first BWP to the second BWP based on the at least one of the allowed interruption duration or the allowed BWP switch delay.

Abstract: A user equipment that selects at least one synchronization signal block (SSB) resource ID based on measurements of a second signal block, wherein the second signal block comprises a system information block (SIB) in 5G new radio (NR) that is spatially quasi co-located (QCLed) with the SSB resource ID, generates a beam reporting message including the selected SSB resource ID(s) and transmits the beam reporting message to a base station. A next generation NodeB (gNB) in a wireless network including the gNB and a UE that allocates downlink (DL) reference resources (RS) in a frequency range for the UE, wherein the DL comprise SIB occasions, each associated with a synchronization signal block (SSB) resource identification (ID) and receives reporting messages containing measurements by the UE for the DL RS.

Abstract: An approach is described to for new radio (NR) antenna test function (ATF) measurements by a user equipment (UE). The approach includes measuring a first average phase of receive signals on resource elements that carry secondary synchronization signals (SS) received by a reference individual receiver branch. The approach also includes measuring a second average phase of the receive signals on the resource elements that carry secondary synchronization signals received by one other individual receiver branch different from the reference individual receiver branch. The approach further includes determining a difference between the first average phase and the second average phase. An indication of the difference is reported to test equipment.

Abstract: A user equipment (UE) is configured to change a transmission configuration indicator (TCI) state. The receives, from the base station, a network flag indicating a transmission configuration indicator (TCI) state change configuration for the network, determines a time span for continuing to use a current TCI state prior to switching to a new TCI state based on the network flag and switches to the new TCI state after the time span.

Abstract: A base station communicates with a first user equipment (UE) and a second UE. The base station determines a first configuration for the first UE for a channel state information reference signal (CSI-RS) on a symbol, schedules a data transmission for the second UE on the symbol where the CSI-RS is configured so that the CSI-RS and the data transmission collide on the symbol and determines a second configuration for the first UE when the CSI-RS and the data transmission collide on the symbol.

Abstract: A computer readable storage medium, a user equipment, a method and an integrated circuit that are used to perform operations. Operations include receiving, from a network, a plurality of Physical Downlink Shared Channel (PDSCH) transmissions in slots of a hybrid automatic repeating request acknowledgement (HARQ-ACK) window, decoding each of the PDSCH transmissions in the slots of the HARQ window, determining a HARQ-ACK feedback for each PDSCH transmission in the HARQ-ACK window, bundling the HARQ-ACK feedback for at least two of the PDSCH transmissions and reporting the bundled HARQ-ACK feedback for the HARQ window to the network.
