Embodiment Construction

[0022] Briefly described, a technical solution is provided that will enable efficient utilization of available communication resources in the uplink in a wireless communication network.

[0023] When multi-bearer UEs are used, the scheduler may be designed to schedule UEs that request transmission of data for priority services in the uplink before UEs request transmission of data for lower priority services in the uplink, i.e. Services for which priority radio bearers are used before services for which lower priority radio bearers are used. When scheduling, the scheduler may calculate and give grants per UE, but UEs requesting scheduling request a specific QoS (Quality of Service) per radio access bearer and thus indirectly per radio bearer. However, as described above, prioritizing UEs based on services / radio bearers enables abuse / misuse of communication resources. For example, a UE or a user of a UE that wishes to perform a lower priority service but wishes to be scheduled ...

Abstract

A method performed by a communication network node for scheduling a UE in a communication network comprising a user equipment (UE) and a communication network node is provided. The UE is arranged to communicate data with a communication network node over a plurality of bearers. In the method, one or more active bearers among the plurality of bearers are determined (202), a highest priority of the active bearer is determined (204) and data transmission in uplink is scheduled (208) for the UE based on the highest priority. By considering only active bearers when scheduling, UEs with inactive high-priority bearers are prevented from performing free-riding traffic on lower-priority bearers.

Description

technical field [0001] The present disclosure generally relates to methods and apparatus for scheduling uplink data in a communication network, in particular for scheduling uplink data in a wireless communication network. Background technique [0002] In a wireless communication network, a user uses a UE (User Equipment) for communicating with a RAN (Radio Access Network). As services become available, users increase their data traffic and demand more efficient UEs. One type of more efficient UE that has been developed is a multi-bearer UE, ie UEs employ more than one radio bearer per application in their communication with a wireless communication network node. [0003] In this description, the term "user equipment" will be used to denote any suitable communication terminal adapted to communicate with a radio base station. A UE may be implemented as a mobile phone, a PDA (Personal Digital Assistant), a handheld computer, a portable computer, and the like. A "radio base s...
