Embodiment Construction

[0038]The basic concept of the present invention is: when the network side constructs the same-frequency neighbor cell list, if it is judged that a certain neighbor cell is the main carrier frequency same-frequency neighbor cell of the UE, then fill in the PCCPCH transmit power information of the neighbor cell into the measurement control command Otherwise, do not fill it in; after receiving the measurement control command, the UE judges whether the adjacent cell is the main carrier frequency of the UE by judging whether the corresponding cell information in the same-frequency adjacent cell list contains PCCPCH transmit power information The same-frequency neighbor cell, and then decide whether to initiate PCCPCH measurement for the neighbor cell. If the cell information contains PCCPCH transmission power information, the UE considers that the same-frequency neighbor cell is the same-frequency primary carrier, and needs to perform PCCPCH measurement on it; otherwise, the UE con...

Abstract

The invention relates to a method for a terminal to obtain attribute of a neighboring region with the same frequency in a multi-carrier frequency TD-SCDMA system and a measuring method. The method comprises the following steps: during construction of a neighboring region list with the same frequency, a network side fills the basic common control physical channel (PCCPCH) emission power information of the neighboring region into the region information of the neighboring region list with the same frequency if a neighboring region is determined to be the neighboring region in the same frequency of the primary carrier frequency of the current terminal UE, otherwise the network side does not fill the PCCPCH emission power information of the neighboring region into the region information of the neighboring region list with the seam frequency ; the neighboring region list with the same frequency is transmitted to the UE via a measurement control command after judging the attribute of all neighboring regions; after receiving the list, the UE judges whether the corresponding region is a primary carrier frequency neighboring region with the same frequency or an auxiliary carrier frequency neighboring region with the same frequency by judging whether each region information in the neighboring list with the same frequency contains the PCCPCH emission power information, if so, PCCPCH measurement is initiated to the corresponding region, and otherwise, the PCCPCH measurement is not initiated. By adopting the invention, the problem of protocol compatibility is avoided based on the presence or absence of the PCCPCH emission power.

Description

technical field [0001] The invention relates to the field of wireless communication, and mainly provides a method for a terminal in a multi-carrier frequency TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system to acquire attributes of co-frequency adjacent cells and a method for measuring it. Background technique [0002] The terminal of the TD-SCDMA system can remove the same-frequency interference of adjacent cells through the method of joint detection. At present, the terminal can obtain the information of the interfering cell by reading the same-frequency neighbor cell list in the measurement control command. Otherwise, the terminal (UE) needs to traverse all the possible parameters configured at this frequency point to search for possible interfering cells, and such computation is basically impossible for the terminal. Therefore, the most effective way is for the terminal to obtain a list of all possible interfering cells from the network side. ...
