摘要:
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.

A method of transmitting/receiving a packet using a hybrid automatic repeat request in the mobile communication system is disclosed. The packet data transmitting method includes transmitting at least one sub packet divided from plurality of encoded packets generated by repeating a bit stream that is made by encoding information desired to be transmitted with ⅕ rate turbo encoder, and transmission start point information of the sub packet through the sub packet identifier field on the accompanying control channel.

摘要:
The data transmission rate on the reverse link in a mobile communications system is controlled by determining an interference level at a base station due to signals from all mobile stations served by the base station, and determining a transmission energy level required for each mobile station. The interference level is compared with the transmission energy level to obtain a comparison result for each mobile station, and each mobile adjusts its data transmission rate based upon the comparison result, which is sent via a common channel on a forward link to each mobile station in a dedicated manner. Thereafter, packet data is transmitted on the reverse link in accordance with the adjusting so that data throughput can be maximized.

摘要:
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.
