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.

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: 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: Systems, methods, and apparatuses disclosed herein can operate on an unlicensed spectrum. These systems, methods, and apparatuses can perform a first listen-before-talk (LBT) operation of a LBT protocol in a first slot from among multiple slots to determine whether the unlicensed spectrum is unoccupied. Thereafter, these systems, methods, and apparatuses can transmit an uplink (UL) transmission in other slots from among the plurality of slots in response to the unlicensed spectrum being unoccupied. Otherwise, these systems, methods, and apparatuses can perform a second LBT operation in a second slot from among the plurality of slots in response to the unlicensed spectrum being occupied.
