Problems solved by technology
[0005] The time-frequency resource block used to transmit the pilot measurement information may also transmit communication data, and the UE cannot determine whether the transmission in the time-frequency resource block is pilot measurement information, because the communication data and the pilot measurement information use If the power is different, if the information transmitted by the time-frequency resource block used to transmit the pilot measurement information is communication data, the signal quality detection result obtained by the UE according to the communication data will be inaccurate, which will cause the signal quality of the entire adjacent cell to be incorrect. Inaccurate quality test results

Embodiment Construction
[0026] In order to solve the problem that the user terminal cannot determine whether the information transmitted in the time-frequency resource block is pilot measurement information, which causes the user terminal to inaccurately detect the signal quality of adjacent cells, the embodiment of the present invention provides a method for information transmission and acquisition , devices and systems.
[0027] Such as figure 1 As shown, the method for sending information provided by the embodiment of the present invention includes:
[0028] Step 101, obtaining antenna configuration information of adjacent cells;
[0029] Step 102, sending a message carrying the antenna configuration information of the adjacent cell to the user terminal.
[0030] The information sending method provided by the embodiment of the present invention can send the antenna configuration information of the adjacent cell to the user terminal, so that the user terminal can accurately know the number of ant...

An embodiment of the invention discloses an information sending and obtaining method, an apparatus thereof and a system thereof, relates to the communication field, and is aimed at solving a problem that since a user terminal can not determine whether information transmitted in a time frequency resource block is pilot frequency measurement information, detection of signal quality of an adjacent cell by the user terminal is not accurate. A technical scheme provided in the invention is as follows: acquiring antenna configuration information of the adjacent cell; sending a message carrying the antenna configuration information of the adjacent cell to the user terminal. The embodiment of the invention can be applied to a wireless communication network.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for sending and acquiring information. Background technique [0002] When cell reselection or handover is required, the user terminal (User Equipment, UE) needs to detect the signal quality of the adjacent cell, and send the detection result to the base station of the current cell, and the base station will check the signal quality of the adjacent cell according to the detection result. The UE performs operations such as cell handover or reselection. [0003] In a wireless communication system, a cell may have multiple transmit antennas, and the coverage of each transmit antenna may be different. In order to ensure the accuracy of cell signal quality detection, the UE needs to monitor multiple or all transmit antennas in adjacent cells. Signal quality testing is performed. In the prior art, the base station of an adjacent cell can send pilot measure...
