Abstract
The present invention relates to methods and arrangements of a network node and a UE of a radio access network supporting discontinuous reception, offering a solution that is based on the idea to use more than one sub frame for transmitting paging messages when needed. An indicator in a sub frame with paging messages indicates to the receiving UE if the subsequent sub frame should be read as well.

A method for paging for a radio access network providing communication services to at least one user equipment, wherein the network, and the user equipment support discontinuous reception, and wherein a sub frame used for paging messages comprises a control part and a data part, said method comprising the steps of:
- transmitting paging messages in the data part of a first sub frame;
- transmitting a further paging message in the data part of a sub frame subsequent to the first sub frame, when the data rate of the first sub frame is not high enough for transmitting all paging messages;
- and
- indicating by an indicator in the first sub frame if the control part of the sub frame subsequent to the first sub frame should be decoded.
A method for paging for a user equipment of a radio access network, wherein the user equipment and the network support discontinuous reception, and wherein a sub frame used for paging messages comprises a control part and a data part, said method comprising the steps of:
- receiving a first sub frame comprising paging messages in the data part and an indicator indicating if the control part of a sub frame subsequent to the first sub frame should be decoded;
- decoding the indicator;
- receiving and decoding the control part of the sub frame subsequent to the first sub frame, when the indicator indicates that the control part of the sub frame subsequent to the first sub frame should be decoded, and
- going into sleep mode when the indicator indicates that the control part of the sub frame subsequent to the first sub frame should not be decoded.
A network node of a radio access network providing communication services to at least one user equipment, wherein the network and the user equipment support discontinuous reception, and wherein a sub frame used for paging messages comprises a control part and a data part, said network node comprising:
- means for transmitting paging messages in the data part of a first sub frame, and
- means for transmitting a further paging message in the data part of a sub frame subsequent to the first sub frame, when the data rate of the first sub frame is not high enough for transmitting all paging messages, and
- means for indicating by an indicator in the first sub frame if the control part of the sub frame subsequent to the first sub frame should be decoded.
A user equipment of a radio access network, wherein the user equipment and the network support discontinuous reception, and wherein a sub frame used for paging messages comprises a control part and a data part, said user equipment comprising:
- means for receiving a first sub frame comprising paging messages in the data part and an indicator indicating if the control part of a sub frame subsequent to the first sub frame should be decoded;
- means for decoding the indicator;
- means for receiving and decoding the control part of the sub frame subsequent to the first sub frame, when the indicator indicates that the control part of the sub frame subsequent to the first sub frame should be decoded, and
- means for going to sleep mode when the indicator indicates that the control part of the sub frame subsequent to the first sub frame should not be decoded.
