Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a connectivity request originated by a user equipment towards a next generation core network may be processed by the next generation core network. The next generation core network may then provide the user equipment an indication of whether the next generation core network supports an inter-RAT handover between the next generation RAT and a legacy RAT.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes configuring a relay selection rule; receiving at least one discovery message from each of a plurality of proximity services (ProSe) relay candidates providing access to a network; evaluating the received discovery messages with respect to the relay selection rule; selecting a first ProSe relay candidate from the plurality of ProSe relay candidates based at least in part on the evaluating; and connecting to the network via the first ProSe relay candidate. A method for wireless communication at a ProSe relay candidate includes receiving, from a network, a ProSe Relay Indication (PRI); broadcasting at least one discovery message that includes the PRI; and receiving a relay connection request from a UE based at least in part on a compliance of the at least one discovery message with a relay selection rule of the UE.

Abstract: A core network receives data from at least one of an AF, a DN, or a UE. A UPF having small data capability processes the data for transport with a low overhead and without initiating a bearer set up protocol. The data may be transported between the UE and the UPF as an RRC payload over a NAS protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as an RRC payload. The data may be received as uplink data from a UE, e.g., in an RRC payload. The UPF may process the RRC payload to obtain the data and may transport the data to the AF or DN. The UPF may perform IP header compression, data encryption, and/or buffering of data for a UE in an idle mode.

Abstract: Aspects encompassing public land mobile network (PLMN) configurations are disclosed. In one example, first and second PLMN configurations are determined, and a parameter having a common identifier between a hybrid PLMN and a PLMN from a different PLMN configuration is identified, such that the hybrid PLMN may connect with a first or second core network type. Inclusion of the common identifier is limited to either the first or second PLMN configuration via an index, and the first and second PLMN configurations are transmitted. In another example, first and second PLMN configurations are received, and a hybrid PLMN in one of the two PLMN configurations is selected. A determination is made whether to use the hybrid PLMN to connect with a first or second core network type. Whether a hybrid PLMN parameter was ascertained via the first or second PLMN configuration is reported. Other aspects, embodiments, and features are also included.

Abstract: Methods and apparatus for configuring a UE to assist in mitigating network congestion include determining whether a data packet has expired based on a first parameter, which indicates an expiration of the data, and adjusting a transmission of the data packet based on the determination of whether the data packet has expired. In some aspects, the UE may drop the data packet upon determination that the data packet has expired. The UE may be configured detect to a first congestion level, receive a second congestion level from a second UE, and process a frame for transmission based on the first or second congestion level. The UE may be configured determine a priority, generate a data packet that includes a destination parameter or a source parameter, adjust radio resource parameters based on the destination parameter or source parameter, and transmit data packets according to adjusted radio resources.

Abstract: Techniques for optimizing user equipment radio capability signaling for wireless communications are described. In one technique, a type of network to access for communications is determined. A capability identifier(s) associated with a set(s) of user equipment (UE) radio capabilities is determined based, at least in part, on the type of network. The capability identifier(s) is sent to the network. Upon receiving an indication of the capability identifier(s), the set(s) of UE radio capabilities associated with the capability identifier(s) is identified and stored.

Abstract: Techniques described herein are directed toward enabling location support for 5G New Radio (NR) wireless access by a user equipment (UE) by utilizing existing LTE location support. More specifically, LTE positioning protocol (LPP) messages may be communicated between a UE with NR wireless access and a location server (e.g. an LMF) in a 5G Core Network via an NG-RAN. The LPP messages may support RAT-independent and E-UTRA position methods by the UE such as A-GNSS or OTDOA for E-UTRA. The location server may obtain OTDOA related information from eNBs and ng-eNBs supporting LTE wireless access. A UE may request measurement gaps from a 5G base station (e.g. gNB) in order to obtain measurements for RAT-independent and E-UTRA position methods and may request an idle period in order to obtain LTE timing needed for E-UTRA measurements.

Abstract: A user equipment (UE) may be outside of the coverage area of a base station or other access point, which may impede access by the UE of a core network, server, or the like. Therefore, a UE may establish a relay connection to access resources when the UE is outside of a coverage area provided by a base station or access point. In aspects, an apparatus may be configured to transmit, to a set of relay UEs, a first message associated with establishment of a relay connection. The apparatus may be further configured to receive a set of messages from the set of relay UEs. The apparatus may be further configured to establish the relay connection with a first relay UE of the set of relay UEs based on a message of the set of messages from the first relay UE.

Abstract: Methods, systems, and devices are described for Wireless Local Area Network (WLAN) offloading through radio access network rules. In one embodiment of a method of wireless communication, a mobile device may determine that Radio Access Network (RAN) assistance information is unavailable, the RAN assistance information including a first set of thresholds for switching a Packet Data Network (PDN) connection of the mobile device from a WLAN to a Wireless Wide Area Network (WWAN). The mobile device may further access a second set of thresholds based at least in part on the determining, and the mobile device may determine to switch the PDN connection from the WLAN to the WWAN based at least in part on the second set of thresholds.
