Embodiment 1

[0073] Embodiment 1 of the present invention provides a method for determining the channel quality of a communication system, such as figure 1 Shown is the schematic flow chart of this method, specifically comprises the following steps:

[0074] Step 101, the network side sends measurement configuration information to the terminal.

[0075] When the network side needs to measure the channel quality of a certain communication system to determine whether to perform cell handover or other related operations, it sends measurement configuration information to the terminal, instructing the terminal to measure the channel quality of the corresponding communication system according to the measurement configuration information and report.

[0076] In this embodiment and the following embodiments, the interaction between the network side and the terminal may be implemented through the interaction between the network side device and the terminal.

[0077] Before step 102, the method al...

Embodiment 2

[0100] Embodiment 2 of the present invention provides a method for determining the channel quality of a communication system, such as figure 2 Shown is the schematic flow chart of this method, specifically comprises the following steps:

[0101] Step 201, the network side sends measurement configuration information to the terminal.

[0102] Similar to Embodiment 1, when the network side needs to determine whether to perform cell handover or other related operations by determining the channel quality of a certain communication system, it sends measurement configuration information to the terminal, instructing the terminal to perform corresponding communication based on the measurement configuration information. The channel quality of the system is measured and reported.

[0103] Similar to Embodiment 1, before step 202, step 201' may be included: the network side sends time division multiplexing mode indication information to the terminal, and the terminal allocates each comm...

Embodiment 3

[0116] Such as image 3 As shown, Embodiment 3 of the present invention provides a network side device, the network side device includes a receiving module 11 and a channel quality determination module 12, wherein:

[0117] The receiving module 11 is used to receive the measurement result of the channel quality in the specified time slot reported by the terminal, and the specified time slot is a time slot specified by the network side and the terminal in advance or by sending instruction information to the terminal; the channel quality determination module 12 is used for According to the received measurement results, the channel quality of the communication system to be measured is determined.

[0118] The network side device sends indication information to the terminal based on the radio resource control RRC signaling through its own sending module 13 .

[0119] The sending module 13 is also used to send time-division multiplexing mode indication information to the terminal,...

Abstract

The embodiment of the invention provides a method, a system and a device for determining the channel quality of a communication system. The method particularly comprises the following steps that a network side assigns the way of a time slot through previously appointing or sending indication information, requires a terminal to report the measurement result of the channel quality in the assigned time slot, and determines the channel quality of the communication system according to the measurement result; or, the terminal reports time slot measurement information corresponding to the measurement result of the channel quality while reporting the measurement result of the channel quality, and the network side selects the measurement result of the relevant time slot of the communication system from the measurement result reported by the terminal as required to determine the channel quality of the communication system. Therefore, the problem in the prior art that the measurement results of the channel quality belonging to different time slots cannot be distinguished to cause that the channel quality of the communication system cannot be determined accurately is solved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, system and device for determining channel quality of a communication system. Background technique [0002] In a mobile communication system, in order to ensure that a terminal can obtain consistent services in a mobile state, it is necessary to constantly change the cell serving the terminal. In the long-term evolution (LTE, long term evolution) system, if the terminal is in the idle (standby) state when the cell is changed, this cell change is called cell reselection; if the cell is changed, the terminal is in the connected (communication) state, This cell change is called cell handover. Regardless of cell reselection or cell handover, the criterion for triggering this process is the strength of the network signal of the communication system in the cell (the quality of the channel), and the strength of the network signal of the communication system in the cell is...
