Abstract: Methods, apparatus, and systems are described for improved edge network access for a UE. According to some aspects, a UE may receive a first Data Network Name (DNN) from an application and determine, based on a Data Network Name (DNN) Replacement Rule, the first DNN is associated with a second Data Network Name (DNN), where the first DNN and the second DNN are different. The UE may determine, based on the DNN Replacement Rule, to associate traffic from the application with a Protocol Data Unit (PDU) Session, where the PDU Session may be used to send data from the application to a network and the PDU Session is associated with the second DNN.

Abstract: A method performed by a STA may comprise transmitting a first negotiation message to an AP and receiving a second negotiation message from the AP. The first negotiation message and the second negotiation message may negotiate a block acknowledgement agreement between the STA and the AP. The method may further comprise receiving a data unit, from the AP, the data unit having a duration field indicating a duration of a block-ACK frame. The duration of the block-ACK frame may be determined based on the negotiated block ACK agreement. A block-ACK frame may be transmitted within the duration indicated by the duration field.

Abstract: Methods and systems are disclosed for a more flexible use of bandwidth parts (BWP) and cells for the various transmissions within the BFR procedure, such as the UL beam failure recovery request (BFRQ) and the DL beam failure recovery response (BFRR). The proposed framework allows these transmission to occur in BWPs with different Id, as well as on different cells. Example benefits include support for BFR on DL-only SCells by allowing the BFR UL transmissions on another cell with UL, support for sequential/parallel multi-cell BFRQ for improved BFR reliability and latency performance, and support for less UE-initiated BWP switching for BFR.

Abstract: In one implementation, we improve the binary voxel-based octree coding method, via a proposed state summarization module for context modeling. Given a current voxel to be encoded or decoded, instead of directly estimating its occupancy probability based on the associated binary occupancy context, a proposed state summarization module is applied to convert the original binary context to a summarized representation. Under the summarized representation, the estimation of the occupancy probability becomes more affordable and effective. In particular, density-based state summarization, pattern-based, learning-based state summarization, and learning-based state summarization methods are provided.

Abstract: Methods, apparatus and systems are disclosed. In one representative method, a wireless transmit and receive unit (WTRU) may receive information associated with one or more configured grants (CGs), may select a first CG corresponding to a first CG configuration, and may transmit, on a CG occasion associated with the first CG, a transport block (TB) using resources associated with the first CG. The WTRU may also start a CG timer for the first CG responsive to a transmission of the TB, and receive a HARQ Acknowledgement (ACK) indication indicating a HARQ-ACK feedback value and associated with a HARQ Process ID (PID) in Downlink Feedback Information (DFI) of Downlink Control Information (DCI). In this representative method, after reception of the HARQ ACK indication and on condition that a HARQ-ACK feedback value is equal to ACK, the WTRU may stop the CG timer and may flush a HARQ buffer associated with the HARQ PID.

Abstract: 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.

Abstract: Systems, methods, and devices for efficient and robust handling of acknowledgements in new radio unlicensed bands (NR-U) environments. A wireless transmit receive unit (WTRU) may receive control information and a data transmission from a gNB in a first interval (i.e., transport block or channel occupancy time), wherein the control information may include an indication of uplink resources. The data transmission may require some sort of acknowledgement (i.e., HARQ feedback). The WTRU may attempt to transmit the acknowledgement in the indicated uplink resources, but the gNB may not receive the acknowledgement. The WTRU may receive control information and a data transmission from the gNB in a second interval, including an indication to aggregate any previously unsuccessful acknowledgement transmissions. The WTRU may transmit an aggregated acknowledgement including previous unsuccessful acknowledgements and any additional acknowledgements from the current interval. In some cases, look-before-talk procedures may be used.

Abstract: A method performed by a base station may compromise: detecting an interference pattern; determining that the interference pattern impacts one or more code blocks (CBs) within one or more code block groups (CBGs); adjusting a size of the one or more CBGs; and transmitting, to a wireless transmit/receive unit (WTRU), information associated with the adjusting of the size of the one or more CBGs. The interference pattern may be caused by a radio detection and ranging (RADAR) system. The adjusting of the size of the one or more CBGs may compromise increasing or decreasing the number of CBs within the one or more CBGs. The transmitting of the information relating to the adjusting of the size of the one or more CBGs may be performed via master information block (MIB) signaling, radio resource control (RRC) signaling, or downlink control information (DCI) signaling.

Abstract: Methods and apparatuses are described herein for synchronization enhancement in new radio non-terrestrial networks. In an example. a UE may determine a distance between the UE and a satellite of a NTN. The UE may determine a reference distance associated with the satellite. The UE may determine a differential delay associated with the UE based on the distance between the CE and the satellite and based on the reference distance. Based on the differential delay. the UE may determine a timing advance associated with the UE and the NTN.
