Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and in particular, to a method and device for sending and receiving information. Background Art

[0002] Generally speaking, after the terminal is configured with the Connect Discontinuous Reception (CDRX) function in the connected state, the technical effect of energy saving can be achieved. However, the defect of the terminal configuring the CDRX function is that when the terminal enters the sleep state in the connected state, it will not send a channel sounding reference signal (SRS) signal and report a channel state information (CSI) measurement report to the base station. Therefore, when the terminal enters the active state from the sleep state, the base station will not be able to obtain continuous measurement information of the terminal, so that the base station cannot accurately estimate the channel quality of the terminal, reducing the reliability of the base station in scheduling UE. Summary of the invention

[0003] The embodiment of the present invention provides a method and device for sending and receiving information, so as to at least solve the problem in the related art that a terminal does not report CSI and send SRS in a sleep state when a CDRX function is configured.

[0004] According to one embodiment of the present invention, there is provided an information sending method, comprising: when a 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.

[0005] In an exemplary embodiment, the terminal reports the CSI measurement report or sends the SRS in the sleep state, including: when the time for 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 time for reporting the CSI measurement report or sending the SRS arrives, the terminal reports the CSI measurement report or sends the SRS.

[0006] According to another embodiment of the present invention, there is provided an information receiving method, comprising: a base station sends a signaling for configuring a discontinuous reception CDRX function in a connected state to a terminal, and sends a signaling for configuring a channel state information CSI measurement report or a channel sounding reference signal SRS function in a sleep state to the terminal; the base station receives the CSI measurement report or the SRS sent by the terminal.

[0007] In an exemplary 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.

[0008] According to another embodiment of the present invention, there is also provided an information sending device, including: a first sending module, for 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.

[0009] According to another embodiment of the present invention, there is also provided an information receiving device, including: a second sending module, used for the base station to send a signaling for configuring a discontinuous reception CDRX function in a connected state to a terminal, and to send a signaling for configuring a channel state information CSI measurement report or a channel sounding reference signal SRS function in a sleep state to the terminal; a receiving module, used for the base station to receive the CSI measurement report or the SRS sent by the terminal.

[0010] According to yet another embodiment of the present invention, a computer-readable storage medium is provided, in which a computer program is stored, wherein the computer program is configured to execute the steps of any one of the above method embodiments when running.

[0011] According to yet another embodiment of the present invention, there is provided an electronic device, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to run the computer program to execute the steps in any one of the above method embodiments.

[0012] Through the present invention, since 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, the terminal can still report the CSI measurement report or send the 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.

The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, to implement the above-mentioned method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer terminal via a network.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0024] In an embodiment of the present invention, a method for sending information is provided. Figure 2 is a flow chart of a method for sending information according to an embodiment of the present invention. Figure 2 As shown, the process 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 is received in the optional configuration field of the primary service cell group configuration of the multiple access channel as to whether to allow reporting of the CSI measurement report or sending of the SRS in the sleep state, 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 time for 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 time for 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 for 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, or the terminal does not judge the state 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 a non-periodic 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 directly reported or the SRS can be sent, so that low latency can be achieved in reporting the terminal CSI measurement report or sending the SRS.

[0033] In an embodiment of the present invention, a method for receiving information is provided. Figure 3 is a flow chart of an information receiving method according to an embodiment of the present invention. Figure 3 As shown, the process 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 for configuring the CDRX function to the terminal, and sends the RRC signaling for configuring the CSI measurement report or sending the SRS function in the sleep state to the terminal.

[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 a CSI measurement report or send an 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 to allow the terminal 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 of this embodiment, the method further includes: the base station estimates the quality of the downlink service channel of the terminal according to the CSI measurement report.

[0041] After step S304 of this embodiment, the method further includes: the base station estimates the quality of the uplink and downlink service channels 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 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 a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, in essence 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 a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

[0044] In the present embodiment, a device for sending information and a device for receiving information are also provided, and the devices are used to implement the above-mentioned embodiments and preferred implementation modes, and those that have been described are not repeated here. As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware is also possible and conceived.

Figure 4 As shown, the information sending device 400 includes: a first sending module 10, which is used to report the CSI measurement report or send the SRS in the sleep state 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.

Figure 5 is a structural block diagram of an information receiving device according to an embodiment of the present invention. Figure 5 As shown, the information receiving device 500 includes: a second sending module 20 and a receiving module 30.

[0047] The second sending module 20 is used for the base station to send a signaling of configuring a discontinuous reception CDRX function in a connected state to the terminal, and to send a signaling of configuring a reporting channel state information CSI measurement report or a sending channel sounding reference signal SRS function in a sleep state to the terminal;

[0048] The receiving module 30 is configured for the base station to receive the CSI measurement report or the SRS sent by the terminal.

[0051] Figure 6 is a flow chart of a method for sending information according to yet another embodiment of the present invention. Figure 6 As shown, the method comprises the following steps:

[0052] Step S602, the base station sends a signaling for configuring a CDRX function to the terminal;

[0053] Specifically, the base station configures the CDRX function to the terminal by sending RRC UE configuration or reconfiguration signaling, and configures allow CSI-SRS-Tx-Sleep to TRUE (correct) in the existing MAC-CellGroupConfig (main service cell group configuration of the multiple access channel), that is, a new field is added to the existing MAC-CellGroupConfig configuration node: allowCSI-SRS-Tx-Sleep BOOLEAN OPTIONAL, where the field OPTIONGAL (optional) is indicated as an optional configuration field, not a required configuration field; for the principle of reconfiguration, it is defined as "Need M", which means that if the reconfiguration value is not received, the historical value is inherited, which is used to indicate whether the terminal can send periodic SRS or periodic CSI measurement results in the sleep state, where a value of true requires that periodic SRS or periodic CSI measurement results be sent normally in the sleep state.

[0054] Step S604: When the CSI-RS reporting or SRS sending time is reached, the terminal reports a CSI measurement report or sends an SRS;

[0055] Specifically, when the terminal reaches the measurement period of periodic CSI-RS (channel state information-reference signal) 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.

[0056] Step S606, the base station receives a CSI measurement report or performs SRS channel measurement;

[0057] Specifically, the base station does not determine whether the terminal is in the sleep state or the active state, and receives the CSI measurement report or performs SRS channel measurement.

[0058] Step S608: The base station estimates the uplink and downlink service channel quality of the terminal through the CSI measurement report reported by the terminal or the measurement value of the SRS channel.
