摘要:
A method of transmitting packet data in a CDM and TDM mobile data communication system is provided. The method comprises determining priorities of one or more control channels, transmitting control information related to one or more packet data sets to one or more mobile stations through corresponding control channels according to the priorities; and transmitting the one or more packet data sets to each mobile station through one or more data channels that correspond to the one or more control channels, respectively. And, a frame duration of the higher priority data control channel restricts a frame duration of the lower priority data control channel.

The present invention relates to a mobile communication system, and more particularly, to a method of allocating a Walsh code resource. The present invention includes determining an available maximum data rate by comparing a channel information value of a forward link with a first threshold value, determining a data rate based on a quantity of data to be transmitted, terminating to allocate the walsh codes or determining a number of the walsh codes to be requested for the data according to a comparison between the data rates, and determining a number of walsh codes for other terminals by checking a number of remaining walsh codes excluding the number of the requested walsh codes from available walsh codes.

The present invention relates to Walsh Code Allocation (WCA) field in the Packet Data Control Channel. One of the embodiments of the WCA field is use of the WCA field as Last Walsh Code Index (LWCI) field in the message format of the PDCCH. The LWCI field indicates the corresponding last code index or the corresponding number of Walsh codes in a Walsh Code Index (WCI) Table/List/Set. In alternative embodiments, the WCA indicates a general set of Walsh codes or a specific set of Walsh codes in the WCI table. The WCA fields may or may not be used with one of power ranking and sequential decoding, but is preferable used. The WCA field has various advantages including but not limited to efficient use of system resources.
