The invention discloses a joint detection method and detection system of multiple sub-districts with the same frequency. Among them, the same-frequency multi-cell joint detection method includes: according to the size of the spreading factor used by the services carried by different frequency points or time slots, the RNC notifies the baseband unit of the base station or the baseband unit automatically detects to obtain the same-frequency adjacent cell user information . The same-frequency multi-cell joint detection method and detection system of the present invention, according to the situation of configuring the spreading factor used by the service, on the one hand, it is used to select the baseband unit of the base station notified by the RNC or automatically detected by the baseband unit of the base station to obtain the same-frequency neighbors. Cell user information, which avoids the huge pressure on Iub interface information transmission due to the RNC notifying too many configuration information of co-frequency adjacent cells, and also reduces the probability of false detection during automatic detection of baseband units, and improves the performance of data detection .
Description
technical field [0001] The invention relates to a wireless technology, in particular to a joint detection method and detection system of multiple cells of the same frequency. Background technique [0002] The same-frequency multi-cell joint detection algorithm includes the steps of multi-cell channel estimation, same-frequency adjacent cell information acquisition, and multi-cell joint detection. In the prior art, there are many different implementation schemes for obtaining user information in the same-frequency adjacent cell and for joint detection of multiple cells. [0003] The purpose of obtaining user information in the same frequency adjacent cell is to obtain the channelization code information used by the users in the same frequency adjacent cell, so as to construct the system matrix of multi-cell and multi-user participating in joint detection. There are two ways to obtain, one is through the Iub interface, the code channel allocation and occupancy information of ...
