Systems, methods, and devices can be utilized to aggregate downlink millimeter wave (mmWave) frequency resources based on various conditions. In an example method, a connection request for downlink data is received from a user equipment (UE). The example method includes determining that a first congestion level of a first mmWave downlink channel is below a first threshold and determining that a second congestion level of a second mmWave downlink channel is below a second threshold. An activation request is transmitted to the UE. The activation request instructs the UE to activate a first antenna corresponding to the first mmWave downlink channel and to activate a second antenna corresponding to the second mmWave downlink channel. At least a portion of the downlink data is transmitted to the UE over the first mmWave downlink channel and the second mmWave downlink channel.

A user equipment (UE) can be a mobile terminating (MT) device that may receive data from another UE or other network element via a telecommunication network. When a small data payload is available for an MT UE, a base station of the telecommunication network can send a paging message to the UE that includes a Mobile Terminating Small Data Transmission (MT-SDT) paging cause. Based on the MT-SDT paging cause in the paging message, the UE can use Small Data Transmission (SDT) procedures to respond to the paging message. The SDT procedures can allow the UE to obtain the small data payload while the UE remains in a Radio Resource Control (RRC) Inactive state.

Described herein are devices and methods, including a base station and user equipment (UE) and methods implemented by such devices. The base station may communicate using a first band, such as a n105 band, and its first transmit-receive frequency separation. The base station may also communicate with a first UE, the first UE being configured to communicate using a second band (e.g., the n71 band), using a second transmit-receive frequency separation. The first transmit-receive frequency separation may be -51 MHz and the second transmit-receive frequency separation may be -46 MHz. A second UE may communicate with the base station using the first band, and the base station may configure the second UE to use the first transmit-receive frequency separation by utilizing a UE specific channel bandwidth or carrier aggregation.

In a telecommunication network, a Serving Call Session Control Function (S-CSCF) may be coupled with a Fifth Generation (5G) Equipment Identity Register (EIR) via an N17' interface. In some examples, the S-CSCF can use the N17' interface instead of a diameter protocol for communicating with the 5G-EIR. The S-CSCF can send a request to the 5G-EIR including a Permanent Equipment Identifier (PEI) associated with a user equipment (UE). In response, the S-CSCF can receive identity data indicative of whether the UE is authorized, not authorized, partially authorized, or unknown. Based on the identity data, the S-CSCF can authenticate a user equipment (UE) accessing a network. In some examples, the S-CSCF may route requests between a 5G-EIR and an EIR. In some examples, this authentication step can comprise a second-level authentication to identify stolen or fraudulent devices and to prevent such devices from accessing the network.

A timer may be used by a device during registration for one or more services of a telecommunication service provider. The function of the timer is to decrease the time that the device (and, hence, the user of the device) waits for successful registration in instances where the device becomes aware that the user clearly wants to use a service (e.g., make a call). The timer may be configured to start in response to the device receiving user input to establish a communication session during registration, and to stop in response to the device receiving a response indicating a successful registration. If the timer expires during registration, an IMS restoration procedure may be performed to attempt registration using a different approach, which, because of the relatively short duration of the timer, expedites the IMS restoration procedure to establish the session more quickly.

Systems and methods for establishing a communication interface between control functions of a network core and a network data node associated with a user side packet core are discussed herein. The system can enable configuration information to be stored and dynamically updated by the network data node such that control nodes of the user side packet core requesting service from the network core are provided with up to date configuration information associated with active control functions. As control functions are activated and deactivated, the configuration information can be updated to reflect the current state of the network core and ensure that user device connects are routed to active control functions configured to provide user requested services.

This disclosure describes techniques that enable a carrier aggregation of two or more carrier available carriers for uplink transmissions at a base station node. More specifically, a carrier aggregation controller may receive a resource allocation request from a base station node that is associated with an uplink transmission of user plane data from a client device. The carrier aggregation controller may determine a carrier aggregation for the uplink transmission and generate scheduling information for delivery to the base station node that is based at least in part on the carrier aggregation.

A fallback mechanism for managing voice over fifth generation (5G) communications is described. In an example, server computing device(s) associated with a 5G network can receive, from a mobile computing device, a request to initiate a voice call over the 5G network. The server computing device(s) can detect a failure to establish the voice call via the 5G network and responsive to detecting the failure to establish the voice call via the 5G network, the server computing device(s) can send, to the mobile computing device, an indication that the voice call failed. The indication can include an instruction to re-attempt to establish the voice call via a different network, and the instruction can cause the mobile computing device to re-attempt, in association with the request, to establish the voice call via the different network.
