[0024] In an embodiment of the present disclosure, a method for sending information is provided. FIG2 is a flow chart of the method for sending information according to an embodiment of the present disclosure. As shown in FIG2 , the flow chart includes the following steps:

[0025] Step S202: When the terminal is configured with a discontinuous reception CDRX function in a connected state and is configured to report a channel state information CSI measurement report or send a channel sounding reference signal SRS in a sleep state, the terminal reports the CSI measurement report or sends the SRS in the sleep state.

[0026] In step S202 of this embodiment, the terminal is configured with the CDRX function, and is configured to report the CSI measurement report or send the SRS in the sleep state, including: the terminal is configured with the CDRX function through the radio resource control protocol RRC signaling configuration, and is configured to report the CSI measurement report or send the SRS in the sleep state.

[0027] In step S202 of this embodiment, the terminal is configured to report the CSI measurement report or send the SRS in the sleep state, including: the terminal receives the main service cell group configuration of the multiple access channel, wherein the optional configuration field of the main service cell group configuration of the multiple access channel carries an indication of whether to allow reporting the CSI measurement report or sending the SRS in the sleep state.

[0028] If no indication of whether to allow reporting of the CSI measurement report or sending of the SRS in the sleep state is received in the optional configuration field of the primary serving cell group configuration of the multiple access channel, the historical indication is inherited.

[0029] In step S202 of this embodiment, the terminal reports the CSI measurement report or sends the SRS in the sleep state, including: when the moment of reporting the CSI measurement report or sending the SRS arrives, the terminal judges the state of the terminal and whether it is configured to report the CSI measurement report or send the SRS in the sleep state; if the terminal is in the sleep state and is configured to report the CSI measurement report or send the SRS in the sleep state, the terminal reports the CSI measurement report or sends the SRS; or, when the moment of reporting the CSI measurement report or sending the SRS arrives, the terminal reports the CSI measurement report or sends the SRS.

[0030] Among them, when the time comes to report the CSI measurement report or send the SRS, the terminal judges the status of the terminal and whether it is configured to report the CSI measurement report or send the SRS in the sleep state, or the terminal does not judge the status of the terminal and directly reports the CSI measurement report or sends the SRS.

[0031] The time for reporting the CSI measurement report or sending the SRS includes a periodic reporting time and an aperiodic reporting time.

[0032] By judging the status and configuration of the terminal, the CSI measurement report can be reported or the SRS can be sent accurately and reliably; without judging the status and configuration of the terminal, the CSI measurement report can be reported or the SRS can be sent directly, which can achieve low latency in reporting the terminal CSI measurement report or sending the SRS.

[0033] An information receiving method is provided in an embodiment of the present disclosure. FIG3 is a flow chart of the information receiving method according to an embodiment of the present disclosure. As shown in FIG3 , the flow chart includes the following steps:

[0034] Step S302: The base station sends a signaling to the terminal for configuring a discontinuous reception (CDRX) function in a connected state, and sends a signaling to the terminal for configuring a channel state information (CSI) measurement report or a channel sounding reference signal (SRS) function in a sleep state.

[0035] In step S302 of this embodiment, the base station sends a radio resource control protocol RRC signaling to the terminal for configuring the CDRX function, and sends the RRC signaling to the terminal for configuring the CSI measurement report or sending the SRS function in the sleep state.

[0036] In step S302 of this embodiment, the base station configures the terminal to report the CSI measurement report or send the SRS function in the sleep state, including: the base station sends the main service cell group configuration of the multiple access channel to the terminal, wherein the optional configuration field of the main service cell group configuration of the multiple access channel carries an indication of whether to allow reporting the CSI measurement report or sending the SRS in the sleep state.

[0037] Step S304: The base station receives the CSI measurement report or the SRS sent by the terminal.

[0038] In step S304 of this embodiment, the base station receives the CSI measurement report or the SRS sent by the terminal, including: when the moment for the terminal to report the CSI measurement report or send the SRS arrives, the base station judges the state of the terminal and whether it is configured to report the CSI measurement report or send the SRS in the sleep state; if the terminal is in the sleep state and the terminal is configured to report the CSI measurement report or send the SRS in the sleep state, the base station receives the CSI measurement report reported by the terminal or the SRS sent by the terminal; or, when the moment for the terminal to report the CSI measurement report or send the SRS arrives, the base station receives the CSI measurement report reported by the terminal or the SRS sent by the terminal.

[0039] When the time comes for the terminal to report the CSI measurement report or send the SRS, the base station can judge the status of the terminal and whether it is configured to report the CSI measurement report or send the SRS in the sleep state. Since the base station reads the main service cell group configuration of the multiple access channel sent to the terminal, the base station judges whether the terminal is allowed to report the CSI measurement report or send the SRS in the sleep state based on the indication carried in the configuration; it is also possible not to judge the status of the terminal and whether it is configured to report the CSI measurement report or send the SRS in the sleep state, and directly receive the CSI measurement report reported by the terminal or the SRS sent by the terminal.

[0040] After step S304 in this embodiment, the method further includes: the base station estimating the downlink service channel quality of the terminal according to the CSI measurement report.

[0041] After step S304 in this embodiment, the method further includes: the base station estimating the uplink and downlink service channel quality of the terminal according to the SRS.

[0042] Since the base station accurately estimates the channel quality of the terminal based on the obtained continuous measurement information of the terminal, the reliability of the base station in scheduling the UE is increased.

[0043] Through the embodiments of the present disclosure, since the terminal is configured with the CDRX function and is configured to report CSI measurement reports or send SRS in the sleep state, the terminal can still report CSI measurement reports or send SRS in the sleep state, which can solve the problem that the terminal cannot provide continuous channel quality information of the terminal in the sleep state when the CDRX function is configured, thereby achieving the effect of ensuring the reliability of the terminal in the CDRX state.

[0044] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present disclosure, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as a read-only memory / random access memory (ROM / RAM), a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in the various embodiments of the present disclosure.

[0055] Step S604: When the CSI-RS reporting or SRS sending time arrives, the terminal reports a CSI measurement report or sends an SRS;

[0056] Specifically, when the terminal reaches the periodic CSI-RS (Channel State Information-Reference Signal) measurement period or the periodic SRS transmission time, it does not need to determine whether the terminal is in the sleep state or the active state, and directly reports the CSI measurement report or sends the periodic SRS signal.

[0057] Step S606: The base station receives a CSI measurement report or performs SRS channel measurement;

[0058] Specifically, the base station does not determine whether the terminal is in the sleep state or the active state, receive the CSI measurement report, or perform SRS channel measurement.

[0059] Step S608: The base station estimates the uplink and downlink service channel quality of the terminal based on the CSI measurement report or the SRS channel measurement value reported by the terminal.
