Abstract: A user equipment (UE) configured as a relay UE between a remote UE and a base station is disclosed. The UE comprises one or more processors configured to receive a RRC signaling to request for establishing or resuming RRC connection from the remote UE, determine whether to perform an access control check prior to forwarding the RRC Signaling of the remote UE to the base station, and forward the RRC Signaling to the base station based on the determination.

Abstract: Systems and methods are disclosed herein for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality. An IAB node may include a MEC functionality that includes an instance of an application configured for MEC. A UE using the application connects to the network through an access link with the IAB node and establishes a PDU session for traffic of the application with a core network (CN). The CN may determine that the traffic corresponds to the application, and that an instance of the application is present on the IAB node. Accordingly, the CN may instruct the IAB donor to instantiate a remote packet data convergence protocol (PDCP) layer and, in some cases, a remote service data application (SDAP) layer that are configured to route the traffic from the UE for the application to the instance of the application on the IAB node.

Abstract: Systems, methods, and devices are provided for performing cell selection or reselection in networks that include earth moving beams. In one example, a method includes receiving, via a satellite, control information transmitted by a base station indicating that a beam associated with a cell ID has been redirected; in response, measuring a beam strength of the redirected beam; and performing cell re-selection based on the measured beam strength.

Abstract: A user equipment (UE) device comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include comprising establishing a sidelink session with a transmitting UE; configuring the sidelink session to support coordinated resource selection prior to performing the local sensing; performing a local sensing; receiving a PSCCH and a PSSCH from the transmitting UE. The transmitting UE reserves multiple resources. The processor is further configured to perform operations including determining whether a collision happens among the multiple reserved resources; and transmitting the coordination message to the transmitting UE.

Abstract: Techniques discussed herein may enable effective cell identification and paging within a non-terrestrial network (NTN). A base station may map logical cell identifiers, corresponding to satellites, to physical cell identifiers, corresponding to physical or geographic cells. The techniques enable cell identification and paging in both Earth-fixed cell scenarios and Earth-moving cell scenarios, and in scenarios where the satellite moves between countries.

Abstract: Disclosed are embodiments for sidelink (SL) capability exchange via a PC5 link between first and second UEs for configuring inter-UE coordination (IUC). In one embodiment, a method entails generating a radio resource control (RRC) message for the second UE, the RRC message including information to identify supported IUC types of the first UE or provide an indication of which resource allocation mode is supported for IUC; signaling with a first SL unicast transmission to the second UE the RRC message; and receiving through a second SL unicast transmission from the second UE the SL capability of the second UE to configure IUC. Also disclosed are techniques for IUC with a UE configured for mode 1 (network-controlled) sidelink (SL) resource allocation.

Abstract: In 5G/New Radio (NR), sidelink communication refers to a channel for communications directly between devices, e.g., user equipment (UEs), without use of traditional uplink or downlink communication channels. Sidelink Control Information (SCI) is separated into two stages (i.e., SCI stage 1 and SCI stage 2) before being transmitted to configure a user device. A method for configuring sidelink communications for a wireless device includes: obtaining SCI Stage 2 payload information; attaching and distributing cyclic redundancy check (CRC) information to the payload information; performing encoding and rate matching (RM) on the payload information; scrambling the encoded and rate matched payload information; performing modulation on the scrambled payload information; determining a resource mapping for the modulated payload information, wherein the modulated payload information is aggregated across two or more slots (e.g., using different processing operations for at least two slots); and transmitting the modulated payload information according to the determined resource mapping.

Abstract: Disclosed are embodiments for a request and response signaling between first and second user equipment (UE) via a PC5 link for configuring inter-UE coordination. In some embodiments, request signaling entails a first UE identifying a transmit resource pool of the first UE to be sensed or evaluated by the second UE; instructing the second UE to report information indicating a quantity of resources; and instructing the second UE to evaluate the resources to be reported. In other embodiments, response signaling entails a first UE receiving from the second UE a request signal for inter-UE coordination; indicating a set of one or more resources, in which the set is indicated as corresponding to whitelist, blacklist, or collision list; and providing a validity time for resources indicated.

Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.
