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 user equipment (UE) receives a resource allocation for a shared channel transmission that includes mapping modulated symbols of a transport block with a single dedicated hybrid automatic repeat request (HARQ) process number across resource elements for N consecutive slots of the resource allocation, wherein N is at least two. The UE may also receive, from a base station, a demodulation reference signal (DMRS) triggering (DMRS-T) value indicating a DMRS pattern to be used for a physical downlink shared channel (PDSCH) transmission, wherein the PDSCH transmission includes mapping modulated symbols of a transport block with a single dedicated hybrid automatic repeat request (HARQ) process number across resource elements for N consecutive slots of a PDSCH resource allocation, wherein N is at least two and measure transmitted DMRS based on the DMRS pattern corresponding to the DMRS-T value.

Abstract: A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.

Abstract: A first user equipment (UE) is capable of serving as a relay for a second UE using a sidelink connection. The first UE determines that a predetermined condition is satisfied, the predetermined condition associated with the first UE operating as a relay for a second UE, transmits a discovery message and monitors for a signal from the second UE in response to the discovery message.

Abstract: Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.

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.
