Embodiment Construction

[0030] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, well-known functions and constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0031] A PDCCH transmitter and a PDCCH receiver in a mobile communication system supporting packet data transmission according to an embodiment of the present invention are explained below. A PDCCH transmitter is provided with a CRC adder for adding CRC bits to control information so that a receiver can detect errors in the control information. In addition to a mobile communication system, the PDCCH transmitter and receiver may be applied to a communication system in which a packet data service is provided and control information is transmitted for efficient packet data transmission.

[0032] According to the present invention, the PDCCH is configured such that it can support PDCH transmission in ...

Abstract

An apparatus and method for transmitting and receiving a PDCCH for efficient transmission of a PDCH in a communication system supporting a packet data service. PDCCHs according to the present invention enable TDM and TDM / CDM transmission of the PDCH, Especially, CRC generators and CRC checker of the present invention allow a second user to utilize control information on a first PDCCH.

Description

technical field [0001] In general, the present invention relates to an apparatus and method for providing packet data services in a communication system, and in particular, to a method for transmitting and receiving PDCCH (Packet Data Control Channel) to detect packet data transmission and reception Apparatus and methods of the program. Background technique [0002] Although a typical mobile communication system only supports voice services, user requirements and the development of mobile communication technologies have brought about a mobile communication system that additionally supports data services. [0003] In a mobile communication system supporting multimedia services including voice and data services, multiple users receive voice and data services within the same frequency band. To this end, TDM (Time Division Multiplexing) or CDM (Time Division Multiplexing / Code Division Multiplexing) is supported for data transmission. These transport schemes are insufficient to...
