Abstract: Various techniques and approaches described herein may be applied to control congestion at a session management (SM) function (SMF) based on at least one back-off timer maintained at a user equipment (UE). In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE may be configured to establish a protocol data unit (PDU) session with a SMF. The UE may be configured to determine whether a back-off timer associated with the PDU session is terminated. The UE may refrain from sending, to the SMF, data over a control plane associated with the PDU session when the back-off timer is unterminated. The UE may send, to the SMF, the data over the control plane associated with the PDU session when the back-off timer is terminated.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request to establish a multicast session. The request may identify a multicast service session including a multicast quality of service flow. The UE may receive, from a base station wirelessly communicating with the UE, an indication of communication resources for the UE to use to receive multicast packets of the multicast service session from a content provider via a tunnel between a first network node and the base station. The tunnel may be established for the multicast service session based on identifying that the multicast service session lacks an existing tunnel between the first network node and the base station. The UE may identify a discontinuous reception (DRX) cycle for the multicast service session, and receive the multicast packets from the base station according to the indicated communication resources and the identified DRX cycle.

Abstract: The method of wireless communication may include a UE, a base station, and a core network including an AMF. The UE may initiate an update of the paging subgroup ID assigned to the UE by transmitting paging assistance information to the AMF. The paging assistance information may include an expected paging probability of the UE. The base station may initiate an update of the paging subgroup ID assigned to the UE based on the change of RRC connection between the UE and the base station. The core network including the AMF may transmit an updated paging subgroup ID to the UE. The core network including the AMF may configure a set of candidate subgroups associated with the UE, and the base station may update the paging subgroup ID of the UE based on releasing the RRC connection to the RRC inactive state.

Abstract: A method for wireless communication performed by a user equipment (UE) includes transmitting, to a core network, a request for a preferred assignment of a paging occasion subgroup. The method also includes receiving, from the core network, a response indicating whether the request is granted. The method further includes monitoring a first paging occasion within a first paging frame associated with the paging occasion subgroup based on the response indicating the request is granted.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a network access control broadcast including access control criteria associated with connecting to a base station, determining an access category associated with the UE and an access identity of the UE associated with the access category, where the access category of the UE is specific to a reduced capability classification of the UE, and selectively performing a random access procedure to connect to the base station in accordance with the access control criteria, the access identity of the UE, and the access category associated with the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a multicast or broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode (AM). The UE may determine an adjustment of an RLC AM transmission window of a base station. The RLC AM transmission window may be associated with retransmission of RLC packets associated with the MRB. The UE may synchronize an RLC AM reception window of the UE with the RLC AM transmission window based at least in part on determining the adjustment of the RLC AM transmission window of the base station. The RLC AM reception window may be associated with reassembly of RLC packets associated with the MRB. Numerous other aspects are provided.

Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

Abstract: Wireless communications systems and methods related to on-demand communications are provided. A first network entity receives, from a user equipment (UE), a network slice request. The first network entity transmits to a second network entity, a request for capability information associated with the UE based on the UE's network slice request. Additionally, the first network entity receives from the second networking entity, a response indicating the capability information associated with the UE.
