Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] In order to realize the blind user distinction described in the present invention when the code channel allocation information of each user is unknown, a precondition is to accurately detect all code channels actually occupied by all current users. The receiver can detect all the code channels actually occupied by all current users by using the existing code channel detection method, in addition to using a code channel detection method based on multiple basic training sequence codes (Midamble), according to this With the method, the receiving end can accurately detect the code channels actually occupied by all users when the code channel allocation information of each user is unknown.

[0031] After the receiving end confirms the code channels actually o...

Abstract

The invention discloses a blind user distinguishing method based on transferring format combined indication detection. It includes the following steps: receiving end taking transferring format combining indication detection to the all of the channel user occupied to determine channel quantity and channel number; according to the channel quantity and channel number determining different user from the channel. The invention could detect actual the channel occupied by transferring format combining indication information and gain the actual channel quantity and channel number of every user to achieve the distinguishing of blind user.

Description

technical field [0001] The present invention relates to the multi-user data receiving method of Time Division Duplex-Code Division Multiple Access (TDD-CDMA) system, in particular to a kind of blind user discrimination based on Transport Format Combination Indicator (TFCI) detection in TDD-CDMA system method. Background technique [0002] In the third-generation mobile communication system, the data carried on each transmission channel is a data transmission block or data transmission block set that occurs periodically in the transmission time interval (TTI), in order to represent the data transmission block or data transmission block carried by the transmission channel The set information defines the concept of a transport format (TF, Transport Format). Each TF can represent the number of data transmission blocks carried by a transport channel in one TTI and the number of information bits contained in each data transmission block. When multiple transport channels are multi...
