## Abstract

Resource management such as network radio resource management in wireless networks, is described in connection with different aspects.

## Claims

### Claim 1

User entity for communicating via communication resources, on which a client is operative, wherein the user entity comprises
an electronic circuit, or a microprocessor, configured to
determine a fill level of a buffer of the client for buffering a media content retrieved by the client from a server,
derive a set of parameters from a media presentation description received from the server, the set of parameters indicating a bandwidth for each of the versions of different bandwidths of the media content, and
inform a resource manager responsible for assigning the communication resources to a plurality of user entities to which the user entity belongs, on
the fill level, and
wherein the user entity is configured to inform the resource manager on the fill level via messages which indicate, as a first addressee, the resource manager, wherein the first addressee is different from a second addressee as which the server is indicated by media requests sent from the client to the server in order to retrieve the media content from the server.

### Claim 2 (depends on 1)

User entity according to claim 1, wherein the user entity is configured to send the messages in a lower OSI layer than an OSI layer via which the media requests are sent.

### Claim 3

Method for being performed on a user entity on which a client is operative, the user entity communicating via communication resources, the method comprising
determining a fill level of a buffer of the client for buffering a media content retrieved by the client from a server,
deriving a set of parameters from a media presentation description received from the server, the set of parameters indicating a bandwidth for each of the versions of different bandwidths of the media content, and
informing a resource manager responsible for assigning the communication resources to a plurality of user entities to which the user entity belongs, on
the determined fill level, and
wherein the user entity informs the resource manager on the fill level via messages which indicate, as a first addressee, the resource manager, wherein the first addressee is different from a second addressee as which the server is indicated by media requests sent from the client to the server in order to retrieve the media content from the server.
