Description

TECHNICAL FIELD

[0001] The present application relates to the communication technology field, and particularly relates to a communication method, device, system and storage medium. BACKGROUND

[0002] At present, in the process of formulating the latest NR (New Radio, for short) standard (Release-17), one important topic is to extend the existing 5G new air interface frequency band to 52GHz-71GHz. According to different countries and regions, some sub-bands in this frequency band belong to unlicensed bands. Therefore, the coexistence problem of the NR system and the existing wireless access technology, such as wireless local area network (for example, IEEE 802.11 series wireless local area network), must be considered. Therefore, the channel access method suitable for the NR system is an urgent problem to be solved.

[0003] In the existing 802.11ad standard, the channel access method includes that the base station sends a ready to send (RTS) message to the terminal, the terminal receives the RTS message, and then sends a clear to send (CTS) message to the base station according to the interference detection structure, and the base station receives the CTS message and then sends data to the terminal.

[0004] In the above-mentioned 802.11ad standard, before the base station sends data to the terminal, the RTS message and the CTS message are used to realize the communication handshake, which will cause a large signaling overhead, especially in the NR system based on beam transmission, this method will reduce the throughput of the communication system.

[0087] It should be noted that in this article, step codes such as S401 and S402 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the order. When implementing the step, those skilled in the art may execute S402 first and then S401, etc., but these should all be within the scope of protection of this application.

[0088] First, let’s explain the terms involved in this application:

[0089] High-frequency communication system: refers to a communication system with a communication frequency between 52GHz and 71GHz.

[0090] The communication method provided by this application can be applied to Figure 1The communication system architecture diagram shown in FIG. Figure 1 This is a schematic diagram of the communication system architecture provided by this application. Figure 1 As shown, the communication system includes: multiple first devices and multiple second devices. Assume that the first device includes Figure 1 As shown in TX1 and TX2, it is assumed that the second device includes Figure 1 RX1, RX2 and RX3 shown in the figure. Figure 1 The communication system shown can be applicable to different network standards, for example, Global System of Mobile communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), and 5G network standards. Optionally, the above communication system can be a system in a scenario of ultra-reliable and low latency communications (URLLC) transmission in a 5G communication system.

[0091] Therefore, optionally, the above-mentioned first device can be a base station (Base Transceiver Station, referred to as BTS) and / or a base station controller in GSM or CDMA, or a base station (NodeB, referred to as NB) and / or a radio network controller (Radio Network Controller, referred to as RNC) in WCDMA, or an evolved base station (Evolutional Node B, referred to as eNB or eNodeB) in LTE, or a relay station or access point, or a base station (gNB) in a future 5G network, etc., and this application is not limited here.

[0092] When the first device is a BTS, a base station controller, an NB, an RNC, an eNB, a relay station, an access point, or a gNB, the second device can be a wireless terminal or a wired terminal. The wireless terminal can be a device that provides voice and / or other data connectivity to a user by connecting to a wireless network, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. The wireless terminal can communicate with one or more core network devices via a Radio Access Network (RAN), and can be a mobile terminal, such as a mobile telephone (or "cell" phone) or a computer with a mobile termination that interfaces to a wireless modem. The wireless terminal can be a Personal Communication Service (PCS) telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or other device that can connect to a wireless network. The wireless terminal can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or user equipment, and is not limited to a particular device.

[0093] Optionally, the first device can be a wireless terminal or a wired terminal. When the first device is a wireless terminal or a wired terminal, the second device can be a BTS, a base station controller, an NB, an RNC, an eNB, a relay station, an access point, or a gNB.

[0094] In the NR high frequency communication system, first in the high frequency narrow beam case, the transmitting end (for example, the first device in Figure 1 and the receiving end (for example, the second device in Figure 1 can form a narrow transmitting and receiving beam, so the case of forming interference is rare, only in the following Figure 2 or Figure 3 Interference exists only in the case shown.

[0095] Figure 2 A possible scenario provided for the present application is shown. As shown, it includes TX1, TX2, RX1 and RX2, TX1, TX2, RX1 and RX2 are on a straight line, and RX1 and RX2 have the same receiving direction. Figure 2

[0096] Another possible scenario provided for the present application is shown. As shown, it includes multiple access points and a mobile terminal, assuming that the multiple access points include Figure 3 As shown, AP1 and AP2, and assuming that the mobile terminal includes Figure 3 As shown, UE1, wherein AP1 and AP2 can both be in communication connection with UE1, when the communication frequency bands of AP1 and AP2 coincide, UE1 cannot eliminate the interference signal generated by AP1 through a filter to obtain the useful signal generated by AP2, or eliminate the interference signal generated by AP2 to obtain the useful signal generated by AP1. Figure 3 Figure 3 In the above and

[0097] Scenarios, the probability of occurrence in actual application is relatively small, if the RTS / CTS communication handshake method is still used, it will lead to a large signaling overhead, and further reduce the throughput of the communication system. Figure 2 Figure 3 In view of the above technical problems, the present application provides a communication method for reducing the signaling overhead, and further improving the throughput of the communication system.

[0098] In view of the above technical problems, the present application provides a communication method for reducing the signaling overhead, and further improving the throughput of the communication system.

[0099] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0100] Figure 4 The flow of the communication method provided for the present application is shown in Figure 1 . As shown, the communication method includes: Figure 4

[0101] S401: The first device receives a first reference signal.

[0102] Optionally, the first reference signal is a signal carried on the optimal beam of multiple beams transmitted by other devices capable of communicating with the first device.

[0103] In application, the first device can measure multiple beams to determine the optimal beam.​​

[0104] In a possible design, the first reference signal is any one or more of a Channel State Information - Reference Signal (CSI-RS), a demodulation reference signal (DM-RS), a Synchronization Signal and PBCH block (SSB), and a Sounding Reference Signal (SRS). The CSI-RS, the DM-RS, and the SSB can be used for downlink communication, and the CSI-RS, the DM-RS, and the SRS can be used for uplink communication.

[0105] For example, when the first device is a BTS, a base station controller, an NB, an RNC, an eNB, a relay station, an access point, or a gNB, the first reference signal can be any one or more of a CSI-RS, a DM-RS, and a SRS. For example, when the first device is a wireless terminal or a wired terminal, the first reference signal can be any one or more of a CSI-RS, a DM-RS, and an SSB.

[0106] S402: The first device determines an interference value of a transmission channel according to the first reference signal.

[0107] The transmission channel is a communication channel between the first device and the other device.

[0108] Specifically, a Clear Channel Assessment (CCA) is performed on the first reference signal to obtain the interference value of the transmission channel.

[0109] S403: If the interference value is greater than or equal to a first threshold, the first device sends a first instruction.

[0110] Optionally, the first threshold is a preset value pre-stored in the first device. For example, the first threshold can be a threshold 10 dB higher than a noise floor, and the application does not limit this.

[0111] Optionally, the first instruction includes a first identifier, where the first identifier is used to indicate that there is interference on the transmission channel. Specifically, the first instruction is a channel occupy indicator (COI).

[0112] It should be noted that when the other device receives the first instruction, and then determines that the transmission channel has interference according to the first identifier, the other device stops sending the pending data to the first device.

[0113] In a possible design, the first instruction is sent in the following at least one manner:

[0114] by sending through a preset added field in a control channel;

[0115] by sending through a dedicated channel;

[0116] by sending through a control channel having a preset format.

[0117] The communication method provided in this application includes: a first device receiving a first reference signal; the first device determining an interference value of a transmission channel according to the first reference signal; and the first device sending a first instruction if the interference value is greater than or equal to a first threshold. In the above method, the first instruction is sent after the first device determines that the interference value is greater than or equal to the first threshold, which can reduce the signaling overhead of the first device and other devices when performing LBT, avoid the other devices implementing communication handshake through RTS messages and CTS messages before sending pending data to the first device, and improve the throughput of a communication system including the first device and the other devices.

[0118] On the basis of the above embodiments, the communication method provided in this application is described in detail below by taking a second device as an example of the other device in combination with Embodiment 5. For details, please refer to Figure 5 Embodiment.

[0119] Figure 5 The flow of the communication method provided in this application is shown in Figure 2 . As shown in the figure, the communication method includes: Figure 5

[0120] S501: The second device sends a first reference signal to the first device.

[0121] Wherein, the explanation of the second device can be referred to the figure, and will not be repeated here. Figure 1

[0122] S502: The first device determines an interference value of a transmission channel according to the first reference signal.

[0123] S503: The first device sends a first instruction to the second device after determining that the interference value is greater than or equal to a first threshold.

[0124] S504: The second device determines whether the first instruction is received, and the first instruction includes a first identifier, which is used to indicate that the transmission channel has interference.

[0125] ​​If yes, S505 is performed.

[0126] If no, S506 is performed.

[0127] Optionally, the second device determines whether the first instruction is received within a first time period, if the first instruction is received within the first time period, S505 is performed, and if the first instruction is not received within the first time period, S506 is performed.

[0128] Optionally, the first identifier is a pre-set identifier and is used for indicating that the transmission channel between the second device and the first device is interfered.

[0129] S505: The second device determines, according to the first instruction, that the transmission channel is interfered, suspends sending any signal, and re-sends the first reference signal to the first device after the first time period.

[0130] In a possible design, the first time period is a pre-set time slot, sub-frame, or radio frame.

[0131] For example, the first time period can be 30 ms, 100 ms, etc.

[0132] S506: If the second device determines that there is data to be sent, the second device sends the first pending data or the second pending data to the first device, wherein the first pending data is old data that has been sent, and the second pending data is new data that has not been sent.

[0133] Optionally, whether the second device has data to be sent can be determined according to whether there is data in an internal memory data buffer.

[0134] The old data can be obtained by using a last same redundancy version, and the new data can be obtained by using a new redundancy version.

[0135] The communication method comprises the following steps: the second device sends a first reference signal to the first device; the first device determines an interference value of a transmission channel according to the first reference signal; the first device sends a first instruction to the second device if the interference value is greater than a first threshold; the second device determines whether the first instruction is received, the first instruction comprising a first identifier, the first identifier being used to indicate that the transmission channel between the second device and the first device is interfered; if yes, the second device determines that the transmission channel is interfered according to the first instruction, suspends sending any signal, and re-sends the first reference signal to the first device after a first time period; if no, the second device determines that there is data to be sent, and sends first pending data or second pending data to the first device, wherein the first pending data is old data that has been sent, and the second pending data is new data that has not been sent. In the above method, the first device sends the first instruction to the second device after determining that the interference value is greater than the first threshold, so that the second device can avoid implementing the communication handshake through the RTS message and the CTS message before sending the first pending data or the second pending data to the first device, the signaling overhead is reduced, and the throughput of the communication system comprising the first device and the second device is improved.

[0136] On the basis of the above embodiment, the following will be described in combination with Figure 6 The communication method provided in the present application will be further described in detail, and the specific description can be made by referring to Figure 6 the embodiment.

[0137] Figure 6 The flowchart of the communication method provided in the present application is shown in Figure 3 . As shown in the figure, the communication method comprises the following steps: Figure 6

[0138] S601: The second device sends a first reference signal to the first device.

[0139] S602: The first device determines an interference value of a transmission channel according to the first reference signal.

[0140] S603: The first device determines whether the interference value is greater than or equal to a first threshold.

[0141] If yes, S604-S610 are executed.

[0142] If no, S608-S610 are executed.

[0143] S604: The first device sends a first instruction to the second device, the first instruction comprising a group of second identifiers, the second identifier comprising a device identifier of the second device and a sending interval duration, the sending interval duration being used to indicate a time period in which the second device does not send a signal, and the device identifier being used to indicate a device of the second device that executes the sending interval duration.

[0144] ​It should be noted that the first instruction can further include a plurality of second identifiers, each of the second identifiers including a device identifier and a transmission interval duration, the transmission interval duration being used to indicate a time period during which the device does not transmit signals, and the device identifier being used to indicate the device performing the transmission interval duration.

[0145] For example, when there are a plurality of second devices (e.g., each of the second devices is an access point device), each of the second devices has a respective corresponding device identifier, the first instruction includes a plurality of second identifiers, and the device identifier and the transmission interval duration in each of the second identifiers are different.

[0146] Specifically, when each of the second devices can perform the method performed by the second device in this embodiment, the first device can receive the first to-be-transmitted data or the second to-be-transmitted data transmitted by each of the second devices.

[0147] S605: The second device determines whether the first instruction is received within the first time period.

[0148] If yes, S606 is performed.

[0149] If no, S608-S610 are performed.

[0150] In a possible design, the first time period is the transmission interval duration of the second device. For example, the transmission interval duration is a preset time slot, a preset subframe, or a preset radio frame.

[0151] S606: The second device determines, according to the device identifier, that the transmission channel has interference, and retransmits the first reference signal to the first device after the transmission interval duration.

[0152] Specifically, if the second device determines that the device identifier in the first instruction is the same as or corresponds to the pre-stored device identifier, it can be determined that the transmission channel has interference.

[0153] S608: When the second device has data to be transmitted, the second device determines whether there is the first instruction within a preset time period before the current time.

[0154] If yes, S609 is performed.

[0155] If no, S610 is performed.

[0156] The preset time period can be 1 millisecond, 3 milliseconds, etc. Specifically, the present application does not limit the preset time period.

[0157] S609: The first to-be-transmitted data is transmitted, and the first to-be-transmitted data is old data that has been transmitted.

[0158] S610: The second to-be-transmitted data is transmitted, and the second to-be-transmitted data is new data that has not been transmitted.

[0159] It should be noted that when the first device determines that the interference value is less than the first threshold, the first device does not send the first instruction to the second device, and the second device does not receive the first instruction within the preset time length, and then S608-S610 can be executed.

[0160] The preset time length can be 1 millisecond, 3 milliseconds, etc., and the present application does not limit this.

[0161] The communication method includes: the second device sends a first reference signal to the first device; the first device determines an interference value of a transmission channel according to the first reference signal; the first device determines whether the interference value is greater than or equal to a first threshold; if yes, the first device sends a first instruction to the second device, the first instruction including a set of second identifiers, the second identifier including a device identifier of the second device and a transmission interval time length, the transmission interval time length being used to indicate a time period in which the second device does not send a signal, and the device identifier being used to indicate a device of the second device that executes the transmission interval time length; the second device determines whether the first instruction is received within a first time period; if yes, the second device determines that there is interference in the transmission channel according to the device identifier, and the second device retransmits the first reference signal to the first device after the transmission interval time length; if no, when the second device has data to be sent, the second device determines whether there is a first instruction within a preset time period before the current time, if yes, the second device sends first pending data, the first pending data being old data that has been sent, and if no, the second device sends second pending data, the second pending data being new data that has not been sent. In the above method, the first device sends the first instruction to the second device after determining that the interference value is greater than or equal to the first threshold, so that the second device sends the first pending data or the second pending data to the first device according to the first instruction, avoiding the second device from implementing communication handshake through the RTS message and the CTS message before sending the first pending data or the second pending data to the first device, thereby reducing signaling overhead and improving the throughput of a communication system including the first device and the second device.
