The present invention relates to methods and user equipment of processing received data at a user equipment connected to a communications network. The processing comprises steps of receiving radio frames in a receiver of the user equipment, identifying the transport block sizes of the radio frame in the user equipment, and determining whether the received radio frame includes transport blocks that are not directed to the user equipment. |

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS FIG.
1 shows a user plane in a UMTS, wherein the radio access bearer service is offered from SAP 101 to SAP 102 (or in the opposite direction) by the Access Stratum 103.
The protocols on the Radio Interface 104, between a UTRAN 105 and a UE 106, and the interconnection point 107, between the UTRAN 105 and a Core Network 108 (CN), that are linked together to provide the Radio Access Bearer (RAB) service.
The system of FIG.
1 can be used as a base for implementing the present invention.
The present invention considers the data transfer from the UTRAN 105 to the User Equipment 106.
FIG.
1 further shows a Non-Access Stratum 109 that offers higher layer signaling, which is not under consideration of the present invention.
FIG.
2 shows a Radio Interface protocol architecture around a physical layer 201 (Layer 1).
The physical layer 201 interfaces a Medium Access Control (MAC)-layer 202, which is a sub-layer of Layer 2, and the Radio Resource Control (RRC)-layer 203 of Layer 3.
The physical layer 201 offers different transport channels 204 to MAC 202.
MAC 202, in turn, offers logical channels 205 to the Radio Link Controller (not shown in FIG.
2), which is a sub-layer of layer 2.
The physical layer 201 and RRC are connected via SAP 206, which offers control/measurement transportation between the physical layer and Radio Resource Control layer.
The transport channels, which are the main consideration in the present invention, can be dedicated transport channels or common transport channels.
Because, the dedicated transport channels do not require an inband identification of the UE (the dedicated channels transport information to a specific UE), they will not be considered in detail in this presentation.
The consideration of this presentation is directed to common transport channels that are shared by several UEs, and especially to FACH (Forward Access Channel).
FACH is a downlink common transport channel, which is transmitted over the entire cell or over only a part of the cell using e
