Enhanced uplink user entity rate limitation signalling

A user entity adapted for transmitting data said data being receivable by at least a serving node and a non serving node, the user entity comprising:

• at least one processor:
• and
• at least one memory, said memory containing instructions executable by said processor, whereby said user entity is operative to:
• receive a first signal from a serving node granting the user entity permission to transmit at a given signalling rate;
• receive a second signal from a non-serving node instructing the user entity to limit its signalling rate;
• transmit data packets and associating a third signal with the data packet transmission indicating the user entity is using a signalling rate as granted by the serving node;
• transmit data packets and associating a fourth signal with the data packet transmission indicating the user entity wants to be granted permission to use a higher signalling rate than it is currently being permitted to use by the serving node;
• and
• issue a signalling rate limitation signal to the serving node, indicating the user entity having limited its signalling rate below the signalling rate granted to it by the serving node.

A Node B adapted to operate as a non-serving Node B for HSUPA transmissions, the Node B comprising:

• at least one processor;
• and
• at least one memory said memory containing instructions executable by said processor, whereby said Node B is operative to:
• in its role as a non-serving Node B issue a Down signal, instructing a user entity to limit its signaling rate, when an interference level has reached a first level, and
• when the interference level has improved below the first level to a second level, transmit a signal being indicative of a cessation of an interference situation.

A Node B adapted to operate as a non serving Node B for HSUPA transmissions, the Node B comprising:

• at least one processor:
• and
• at least one memory, said memory containing instructions executable by said processor, whereby said Node B is operative to:
• in its role as a non-serving Node B issue a Down signal, instructing a user entity to limit its signaling rate, when an interference level has reached a first level, and
• transmit, a signal being indicative of a cessation of an interference situation, the signal being spontaneous or unsolicited.
