Embodiment Construction

[0047] A wireless communication system, such as a user equipment (UE) or a base station Node B, is used in a code division multiple access (CDMA) communication system. Each communication station has a receiver configured to receive selectively formatted, coded time division duplex (TDD) wireless communication signals. Preferably, each frame length of a system frame format is 10 ms, and each frame has fifteen time slots, wherein, the time slots are used for uplink transmission within a given period of time, and are used by user equipment (UE) to Node B, or for downlink transmission, from Node B to User Equipment (UE).

[0048]As mentioned earlier, the transport channel (TrCH) is used for transmission of user data and signaling between user equipment (UE) and Node B. Multiple Transport Channels (TrCHs) are multiplexed into a single Coded Composite Transport Channel (CCTrCH). The Coded Composite Transport Channel (CCTrCH) data stream is mapped to one or more physical channel da...

Abstract

In a communication station (such as: a User Equipment (UE) or Node B of a 3rd Generation Partnership Project (3GPP) system), wherein the channel-coded signal is within a time slot of a system frame with at least Reception is performed on the physical channel of a coded composite transport channel (CCTrCH) to determine the actual number of transport channel codes of the coded composite transport channel (CCTrCH) in a system frame. Then, a channel code identification algorithm is executed according to the determined number, so as to identify the channel code.

Description

technical field [0001] The present invention relates to a receiving station for a Code Division Multiple Access (CDMA) wireless communication system. More particularly, the present invention relates to a system for wireless data transmission that utilizes channel coding settings to associate data block transmissions of selectable sizes. Background technique [0002] Wireless communication systems are well known in the art. Generally, this type of system has a plurality of communication stations, so as to transmit and receive wireless communication signals between each communication station. Generally, a base station is capable of wireless simultaneous communication with multiple subscriber stations. In the Code Division Multiple Access (CDMA) system specified by the Third Generation Partnership Project (3GPP), the base station is called Node B, the user station is called User Equipment (UE), and Node B and User Equipment (UE) ) The wireless interface between is called Uu ...
