Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the invention more clear, the invention will be described in further detail below with reference to the accompanying drawings and examples.

[0031] In order to realize the blind user discrimination of the present invention when the code channel allocation information of each user is unknown, a precondition is to accurately detect all the code channels actually occupied by all current users. The above-mentioned receiving end detects that all the code channels actually occupied by all the current users can adopt the existing code channel detection method, and in addition can also adopt the code channel detection method based on a plurality of basic training sequence codes (Midamble), according to this According to 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.

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 a multi-user data receiving method in a time division duplex-code division multiple access (TDD-CDMA) system, in particular to a blind user discrimination based on transmission format combination indicator (TFCI) detection in the 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 appears periodically in the transmission time interval (TTI). Set information defines the concept of transport format (TF, Transport Format). Each TF can represent the number of data transport blocks carried by a transport channel in one TTI and the number of information bits contained in each data transport block. When multiple transport channels are multiplexed into a Coded Combined Transport Channel (CCTrCH), the TFs of all these transport channels are combined together to for...
