Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, multiple transmission/reception points (TRPs) may perform a joint transmission to a user equipment (UE) such that the UE may rely on demodulation reference signals (DMRSs) from the TRPs for channel estimation and data demodulation to receive the joint transmission. When TRP transmissions are punctured, which may introduce reception errors at a receiving UE, one or more TRPs may transmit unique DMRSs such that each TRP transmits a DMRS that is unique to the transmitting TRP, transmit DMRSs that are unique to punctured resource elements (REs), or determine to refrain from transmitting on punctured REs. In some cases, TRPs may transmit preemption indications (PIs) to a UE, where the PIs may indicate punctured (e.g., or not utilized) REs to allow the UE to utilize a unique DMRS for channel estimation or to ignore the punctured REs.

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: Methods, systems, and devices for wireless communication are described. A wireless communications system may support techniques for efficient communication between a user equipment (UE) and different entities (or functions) of a core network. Specifically, the UE may interact with a single entity (or function) of a core network (e.g., an access and mobility management function (AMF)), and messages intended for other entities (or functions) may be routed appropriately by this entity. For example, an AMF may receive a message from a UE intended for another entity (or function) of the core network, and the AMF may transmit (or route) the message to the entity (or function). Similarly, the AMF may receive a message from another entity (or function) of the core network, and the AMF may transmit (or route) the message to the UE.
