Abstract: A user equipment (UE) is configured to communicate with a further UE via a sidelink (SL). The UE encodes traffic for transmission to the further UE, wherein the traffic comprises a payload and a medium access control (MAC) subheader, wherein the MAC subheader indicates whether the payload corresponds to non-routed traffic between the UE and the further UE or routed traffic between either one of the UE or the further UE and a base station, wherein an other one of the UE or the further UE functions as a relay for the routed traffic and transmits the traffic.

Abstract: A user equipment (UE) performs a multi-level Downlink Control Information (DCI) monitoring operation. The UE monitors an Anchor-search space set (SSS) of a first resource block (RB) set for downlink control information (DCI) and, when the Anchor-SSS includes DCI, monitors at least one Subordinate-SSS of a second RB set based on at least the DCI detected on the Anchor-SSS.

Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a plurality of control resource sets (CORESETs), selecting at least one reference signal (RS) corresponding to at least one activated transmission configuration indicator (TCI) state in a CORESET, analyzing the at least one RS and determining beam failure detection (BFD) or radio link monitoring (RLM) based on the at least one reference signal selected.

Abstract: A first user equipment (UE) selects a second UE to act as a relay for the first UE. The first UE determines that multiple second UEs are available to operate as a relay for the first UE, wherein the determining is based on measurement data corresponding to communication interfaces between the first UE and each of the second UEs. The first UE selects a second UE from the multiple second UEs and transmits a signal to the second UE.

Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a plurality of control resource sets (CORESETs), selecting a CORESET, wherein the CORESET includes one or more active transmission configuration indicator (TCI) states and determining a default beam or a pathloss reference signal (RS) based on a TCI state. Further operations include receiving a beam indication for a physical downlink control channel (PDCCH), wherein the PDCCH is received via one or more CORESETS, each having a plurality of TCIs, determining if the PDCCH collides with a second signal and determining whether to (a) drop the PDCCH or the second signal or (b) base a quasi co-location (QCL) of one of the PDCCH or the second signal on a QCL of the other one of the second signal or the PDCCH.

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.

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.
