Abstract: A user equipment (UE) that is registered to a stand-alone non-public network (SNPN) can also access services on a public land mobile network (PLMN). The UE accesses the PLMN by transmitting a first signal to a data network, receiving a second signal from the data network in response to the first signal, wherein the second signal identifies a PLMN that is configured to be accessed by the UE via the data network and transmitting a session initiation protocol (SIP) registration request to the PLMN via the data network.

Abstract: Techniques described herein includes solutions for mitigating interference related to antenna switching. A user equipment (UE) may determine a potential for interference to data reception on a second frequency band due to antenna switching associated with transmission of reference signals on a first frequency band. In response to the determination, the UE may select one or more interference mitigation measures based on an operating mode of the UE and one or more UE parameters. An interference mitigation measure may include backing off on a reported value, such as a channel quality indicator (CQI), rank indicator (RI), or reference signal received power (RSRP). The interference mitigation measure may further include skipping reference signal transmission on the first frequency band and the antenna switching associated therewith.

Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN). A UE performs a non-access stratum (NAS) procedure with a public land mobile network (PLMN) of an NTN. The UE receives a NAS message from the PLMN, and the NAS message indicates that the UE is not allowed to access a core network of the NTN. The NAS message may indicate that the UE is not allowed to access the core network of the NTN because a location of the UE is unknown to the NTN, that access to the NTN is not allowed in a country in which the UE is located, or that a location of the UE is not within a country associated with the NTN. The UE modifies its PLMN search procedure responsive to receiving the NAS message.

Abstract: A cellular network includes a first network component configured to i) identify a first session between a first data network and a user equipment (UE), wherein the first session corresponds to a first session management function (SMF), ii) receive data network access information (DNAI) from a network function, the DNAI corresponding to a second data network and iii) select a second SMF that is to be utilized for a second session between the second data network and the UE. The cellular network also includes a second network component configured to i) store a mapping between the DNAI and the second SMF and ii) transmit an indication of the second SMF to the first network component, wherein the first network component selects the second SMF based on the indication.

Abstract: The techniques provide solutions for a user equipment (UE) and base station to switch between T1R4 and 2T4R for sounding reference signals (SRS). The UE and base station may communicate SRS using 2T4R. The UE and/or base station may detect and evaluate a signal quality trigger and/or condition relating to switching from T2R4 to T1R4. The trigger and/or condition may correspond to a channel or radio frequency (RF) quality, conflicting or problematic band combinations used in a non-standalone (NSA) scenario, whether dedicated data subscription (DDS) subscriber identity module (SIM) or non-DDS SIM is being used in a dual SIM dual active (DSDA) scenario, etc. The UE and base station may either continue using T2R4 communications or switch to T1R4 communications based on the trigger and/or evaluation.

Abstract: Embodiments are presented herein of apparatuses, processors, systems, and methods for performing Quality of Service handling procedures. A wireless device may establish a cellular link that provides access to a fifth generation core network. The wireless device may establish a protocol data unit session with a cellular network entity of the fifth generation core network. The wireless device may determine one or more Quality of Service flow descriptions for the protocol data unit session. The wireless device may perform one or more Quality of Service related modifications to the protocol data unit session.
