A communication device 1 determines, between a first physical channel and a second physical channel of the communication device 1, an accommodation state of a session in a wireless resource of the first physical channel. The communication device 1 issues an instruction of changing a part of the wireless resource of the first physical channel to a wireless resource of the second physical channel, based on the above-mentioned accommodation state.

A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE 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 (i) comparing an aggregate frequency bandwidth of the first air-interface connection with an aggregate frequency bandwidth of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters. A user equipment device (UE) and/or network may determine a bearer configuration and/or other parameters based on information or measurements of the UE. The UE and the BS may exchange data using a negotiated configuration.

Techniques for managing access combinations for multiple access protocol data unit (PDU) sessions are described. A communication device may receive control signaling indicating a configuration for a multiple access PDU session associated with a plurality of access links. The plurality of access links may be associated with a first type of access, a second type of access, or a combination thereof. The communication device may select a mode for allocation of a data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the received control signaling. The communication device may allocate the data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the selected mode, and transmit the allocated data flow over the plurality of access links associated with the two types of access.

Methods, a data split unit (200) and a data collection unit (202), for controlling data transmission over two connections used for communication of data from the data split unit to the data collection unit operating in dual connection mode. The data split unit obtains (2:4) a receive split ratio between the two connections as perceived at the data collection unit, and adapts (2:5) a transmit split ratio for distributing data over the two connections based on the receive split ratio. The transmit split ratio may be adapted to reduce or eliminate a difference between the transmit split ratio and the receive split ratio. The transmission of data is then distributed (2:7A,B) over the two connections according to the adapted transmit split ratio.

A method and system for controlling apportionment of uplink data flow of a UE having a first connection with a first access node and a second connection with a second access node. An example system could operate to determine an uplink data apportionment, defining what portion of the uplink data flow the UE should provide on the first connection versus what portion of the uplink data flow the UE should provide on the second connection, where determining the uplink data apportionment is based on (i) a comparison of uplink power headroom of the UE on the first connection with uplink power headroom of the UE on the second connection and/or (ii) a comparison of uplink noise on the first connection with uplink noise on the second connection. Further, the example system could then cause the UE to operate in accordance with the determined uplink data apportionment.

A primary access node adds a secondary access node to deliver wireless communication service to a User Equipment (UE). The primary access node comprises baseband circuitry and a radio. The radio wirelessly receives a measurement report from the UE that characterizes a radio metric for the secondary access node. The baseband circuitry determines insertion loss for the secondary access node and an add threshold for the secondary access node based on the insertion loss. The baseband circuitry determines an add value for the secondary access node based on the radio metric. When the add value exceeds the add threshold, the baseband circuitry transfers network signaling to the secondary access node to serve the UE and transfers user signaling to the UE over the radio. The UE attaches to the secondary access node and the secondary access node delivers the wireless communication service to the UE.

Allocating a physical radio resource for a non-guaranteed bit rate (non-GBR) bearer in a distributed communications system (DCS) is disclosed. More specifically, the method enables a radio circuit in a network node to divide the physical radio resource among a number of non-GBR quality-of-service (QoS) class identifiers (QCIs) based on a number of predetermined scheduling ratios, respectively. The radio circuit can be configured to dynamically rebalance physical radio resource allocation among the non-GBR QCIs such that the network node can maintain the predetermined scheduling ratios or respond to a reconfiguration of the predetermined scheduling ratios among the non-GBR QCIs. As a result, a network operator(s) can dynamically adjust physical radio resource allocation among the non-GBR QCIs based on, for example, subscribers' network usage and plan limits, thus making it possible for the network operator(s) to customize QoS configuration to enable differentiated non-GBR services.
