A method and system for controlling uplink communication from a user equipment device (UE) that has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes comparing a level of antenna pattern efficiency associated with the first air-interface connection with a level of antenna pattern efficiency associated with the second air-interface connection and, based at least on the comparing, configuring an uplink split ratio defining a distribution of uplink user-plane data flow of the UE between at least the first air-interface connection and the second air-interface connection. In an example implementation, this could involve configuring one of the air-interface connections as a primary uplink path to which the UE restricts its uplink communication unless and until a trigger occurs for transitioning the UE to operate in an split-uplink mode.

The disclosed technology is directed towards load balancing baseband units in a communications network. A baseband physical layer 1 unit's functions are disaggregated into Layer 1 (L1) distributed units and radio units, instead of deploying full-fledged baseband units at a service' provider's service areas (cells). A load balancer scales up the number of active distributed units based on increased actual demand, and scales down the active distributed units based on decreased demand The L1 distributed units and radio units can be software-defined network functions, and need not be collocated, whereby the distributed units can be in the cloud or hub remotely located relative to the radio units deployed at the service areas. Examples of load balancing can be load balancing of transmitted data per carrier, per subcarrier, per user equipment, per transmission time interval (TTI/slot), per bearer, or per channel.

An initiating wireless transmit receive unit (WTRU) includes circuitry configured to monitor, by the initiating WTRU, a level of congestion experienced by the initiating WTRU while communicating with the at least one peer WTRU. The initiating WTRU detects that the level of congestion triggers congestion control. The initiating WTRU transmits, based on the level of congestion, at least one message to reconfigure an ongoing communication between the initiating WTRU and the at least one peer WTRU.

A data transmission method and UE. The method includes: performing a target operation on first uplink data according to first information, where the target operation includes: in a case that the first 5 information is used to indicate that a first path is capable of transmitting uplink data, transmitting the first uplink data on the first path, and/or in a case that the first information is used to indicate that a second path is incapable of transmitting target uplink data, and that the first uplink data belongs to the target uplink data, skipping transmitting the first uplink data on the second path; and the first path is 10 a source path between the UE and a source cell, the second path is a target path between the UE and a target cell; or, the first path is the target path, and the second path is the source path.
