System and Method for Resource Block-Specific Control Signaling

摘要

A system and method is disclosed for resource block-specific control signaling in a communication system. Communication data is transmitted using a transmission channel comprising a plurality of resource blocks defined by allocating time-frequency slots in a transmission resource. Resource block control information is transmitted in a “feed-forward” manner to a user end (UE) or group of UEs using channels physically mapped into scheduled resource blocks (RBs) for that user or group of users. Embodiments of the invention provide an RB-specific control channel that comprises RB control elements that are embedded within scheduled resource blocks. The invention, therefore, reduces the amount of control information that must be transmitted by common or shared control channels.

主权项

1. A communication apparatus for use in a wireless communication system, comprising:
signal processing logic configured to receive a data transmission signal comprising a plurality of associated resource blocks within a predetermined frequency band; a control channel processor configured to decode a channel control element corresponding to the communication apparatus, the channel control element comprising a resource block allocation identifier; and a resource block control processor configured to extract an embedded resource block control element from an individual resource block within the plurality of resource blocks using the resource block allocation identifier, wherein the embedded resource block control element comprises predetermined control information for the plurality of associated resource blocks, wherein the association of resource blocks comprising the plurality of resource blocks is accomplished using the resource block control processor and the control channel processor.
