A wireless user device uses a wireless network slice. To use the slice, the wireless user device exchanges source signaling with a source Access and Mobility Management Function (AMF). During the exchange of the source signaling, the wireless user device exchanges target signaling with target AMFs. The wireless user device determines AMF characteristics of the target AMFs based on the target signaling. The wireless user device selects one of the target AMFs based on the AMF characteristics and slice requirements of the wireless network slice. The wireless user device exchanges slice signaling with the selected one of the target AMFs, and in response, exchanges data with the wireless network slice.

Wireless user equipment (UE) control over wireless network slices based on slice requirements

Network circuitry within a wireless User Equipment (UE) transmits a registration request to a first Wireless Access Node (WAN) over a wireless communication link. In response, the network circuitry receives a UE capability inquiry from the first WAN and transmits it to user circuitry within the wireless UE. The user circuitry calculates Key Performance Indicator (KPI) information based on the wireless communication link, accesses UE capability information of the UE based on chipset and enabled functionality in the UE, generates intelligent UE capability information by modifying the UE capability information based on the KPI information, and transmits the intelligent UE capability information to the network circuitry. The network circuitry transmits the intelligent UE capability information to the first WAN and wirelessly exchanges data with a second WAN over a second wireless access link configured based on the intelligent UE capability information to provide wireless communication service for the wireless UE.

Adaptive UE capability indicators

Attaching to additional access nodes and performing handovers responsive to path loss measurements and uplink transmit power levels meeting different thresholds. A wireless device attached to a first access node is experiencing one or more of a threshold path loss or a threshold uplink transmit power is instructed to enable dual connectivity, wherein the wireless device remains attached to the first access node. Embodiments include 5G EN-DC systems that are collocated or distributed.

Dual connectivity based on path loss and transmit power

A primary wireless access node receives signaling that indicates primary power headroom for a User Equipment (UE) when transmitting to the primary wireless access node and secondary power headroom for the UE when transmitting to a secondary wireless access node. The primary wireless access node determines a primary uplink grant and a secondary uplink grant for the UE and transfers the secondary uplink grant amount to the secondary wireless access node. The primary wireless access node wirelessly transfers the primary uplink grant to the UE and wirelessly receives primary user data from the UE based on the primary uplink grant. The secondary wireless access node receives the secondary uplink grant from the primary wireless access node. The secondary wireless access node wirelessly transfers the secondary uplink grant to the UE and wirelessly receives secondary user data from the UE based on the secondary uplink grant.

Wireless data communication service over multiple uplinks

A wireless User Equipment (UE) controls a wireless data service that is received from a wireless communication network over a radio band. In the wireless UE, a radio wirelessly exchanges user data with the communication network over the radio band to receive the wireless data service. The radio wirelessly receives a communication performance metric from the wireless communication network over the radio band. The communication performance metric characterizes the wireless data service received by the wireless UE over the radio band. In the wireless UE, user circuitry translates the communication performance metric into a service instruction for the wireless UE over the radio band. The radio wirelessly transfers the service instruction for the wireless UE to the wireless communication network over the radio band. The wireless communication network modifies the wireless data service for the wireless UE responsive to the service instruction.

Wireless data service control over radio bands in a wireless communication network

A wireless User Equipment (UE) controls a wireless network slice type that has slice requirements. In the UE, source Radio Resource Control (RRC) circuitry exchanges source signaling with a source Access and Mobility Management Function (AMF). During the exchange of the source signaling, target RRC circuitry exchanges target signaling with target AMFs and determines AMF characteristics. The target RRC circuitry compares the AMF characteristics to the slice requirements and selects one of the target AMFs based on the comparison. The source or target RRC circuitry exchange additional target signaling with the selected one of the target AMFs to use the wireless network slice type. User-plane circuitry exchanges user data with the wireless network slice which is controlled by the selected target AMF.

A Fifth Generation New Radio (5GNR) User Equipment (UE) controls power consumption. In the 5GNR UE, control circuitry selects an initial 5GNR transmit power and signals the initial 5GNR transmit power to a 5GNR radio. The 5GNR radio transmits initial 5GNR signals at the initial 5GNR transmit power. The control circuitry identifies an excessive Uplink (UL) Hybrid Automatic Repeat Request (HARQ) Block Error Rate (BLER), and in response, selects a lower 5GNR transmit power and signals the lower 5GNR transmit power to the 5GNR radio. The 5GNR radio transmits subsequent 5GNR signals at the lower 5GNR transmit power. The UL HARQ BLER may be for a Long Term Evolution (LTE) access node.

Wireless communication transmit power control based on hybrid automatic repeat request (HARQ) block error rate (BLER)

A primary wireless access node receives primary power headroom for User Equipment (UE). A secondary wireless access receives secondary power headroom for the UE and transfers the secondary power headroom to the primary wireless access node. The primary wireless access node compares the power primary headroom to the secondary power headroom to determine a primary uplink grant amount and a secondary uplink grant amount for the UE. The primary wireless access node grants primary uplink resources to the UE based on the primary uplink grant amount. The secondary wireless access node grants secondary uplink resources to the UE based on the secondary uplink grant amount. The wireless access nodes receive user data from the UE based on the uplink grant amounts.

A wireless access node exchanges data with User Equipment (UE) over a radio band and determines a performance metric for the UE over the radio band. The wireless access node transfers the performance metric to the UE. The UE translates the performance metric into a service instruction for the radio band and transfers the service instruction to the wireless access node. The wireless access node transfers the service instruction to a network controller. The network controller modifies the wireless data service for the wireless UE over the radio band in response to the service instruction.

A Fifth Generation New Radio (5GNR)/Long Term Evolution (LTE) User Equipment (UE) controls power consumption. The 5GNR/LTE UE selects a 5GNR transmit power and an LTE transmit power. The UE transmits 5GNR signals at the 5GNR transmit power and transmits LTE signals at the LTE transmit power. The UE averages Uplink (UL) Hybrid Automatic Repeat Request (HARQ) Block Error Rate (BLER) for an error sampling period. The UE compares the average UL HARQ BLER to an error threshold. When the average UL HARQ BLER exceeds the threshold, the UE decreases 5GNR transmit power and increases LTE transmit power. The UE may average UL path loss for a loss sampling period and compare the average UL path loss to a loss threshold. The UE may decrease 5GNR transmit power and increase LTE transmit power when the UL HARQ BLER and the UL path loss both exceed their thresholds.
