Abstract

In an embodiment, a composite signaling message part is formed to include at least two segments, each segment including data identifying a different user equipment (UE). In another embodiment, a different portion of a composite signaling message part is transmitted over at least one same time slot in each of the shared control channels; the part including at least two segments and each segment including data identifying a different user equipment (UE). In these embodiments, the part further includes a cyclic redundancy code (CRC) generated by jointly encoding the at least two segments. In a further aspect of the method, more than one shared control channel jointly carrying a signaling message are power controlled such that each shared control channel carrying more data associated with one of the UEs is power controlled in accordance with that UE. In a still further embodiment, the channelized code information for a dedicated control channel is divided between first and second parts of the shared control signals.
