[0034] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The embodiment of the present application can be applied to a sudden interference system. For example, the sudden interference system 100 applied in the embodiment of the present application is as follows: Figure 1 The sudden interference system 100 may include a control device 110 (or referred to as a control node), which may be a device that communicates with a controlled device 120 (or referred to as a controlled terminal). The control device 110 may provide communication coverage for a specific geographical area, and may communicate with controlled devices located in the coverage area.

[0036] Figure 1 One control device and two controlled devices are exemplarily shown. Optionally, the sudden interference system 100 may include multiple control devices and each control device may include other number of controlled devices within its coverage area, which is not limited in the embodiments of the present application.

[0037] Optionally, the burst interference system 100 may further include other network entities, which is not limited in the embodiment of the present application.

[0038] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the shown sudden interference system 100 as an example, the communication device may include a control device 110 and a controlled device 120 with communication functions. The control device 110 and the controlled device 120 may be the specific devices described above and will not be repeated here; the communication device may also include other devices in the sudden interference system 100, which is not limited in the embodiments of the present application.

[0039] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0040] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0041] Optionally, the indication information in the embodiment of the present application includes at least one of physical layer signaling such as downlink control information (Downlink Control Information, DCI), radio resource control (Radio Resource Control, RRC) signaling and media access control element (Media Access Control Control Element, MAC CE).

[0042] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0043] The controlled device in the embodiment of the present application can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self driving, a wireless terminal device in remote medical, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0044] As an example but not limitation, in the embodiment of the present application, the controlled device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0045] In a burst interference system, similar to the current cellular network communication system, the function of the control device is similar to that of a base station in a cellular network, responsible for sending synchronization signals, sending broadcast information, access control, data sending and receiving, sending high-level information, etc.; while the controlled device is responsible for detecting synchronization signals, receiving broadcast messages, sending and receiving data according to the scheduling of the control device, receiving high-level information, etc.

[0046] In the embodiment of the present application, for the convenience of description, the transmission from the control device to the controlled device is called downlink, and the transmission from the controlled device to the control device is called uplink.

[0047] In traditional cellular communication systems, control channels and data channels can use different coding methods based on pre-configured information. For example, in the New Radio (NR) system, when the number of information bits sent by the control channel is less than 11, block coding is used. Otherwise, the control channel uses polarization coding (Polar Code) and the data channel uses low-density parity-check codes (LDPC) coding. For the receiving end, it can receive and decode according to the channel type and the number of bits sent by the channel (known to the receiving end).

[0048] In the burst interference system involved in the present application, due to the existence of certain burst interference sources, there is a need to use different coding methods according to the interference situation, and this coding selection method is not supported in the traditional cellular communication system. In addition, the traditional cellular communication system does not support the selection of different coding methods according to different channel environments, where the channel environment can be a real channel interference environment or a predicted interference environment that may occur.

[0049] From the above analysis, it can be seen that in the solution provided in the present application, for a specific semi-static scheduling configuration, a transmission block within a specific size range, or for a specific channel, the controlled node can dynamically or semi-statically select the encoding method based on one or more of the current time, geographic location, channel interference conditions and other information, thereby improving the system's anti-interference ability by adjusting the encoding method.

[0050] The technical solution of the present application is described in detail below through specific embodiments.

[0051] Figure 2 is a schematic flow chart of a channel coding method 200 according to an embodiment of the present application, such as Figure 2 As shown, the channel coding method 200 may include but is not limited to the following contents:

[0052] S210, the control device sends configuration information to the controlled device.

[0053] The configuration information is used to configure one of the following:

[0054] a channel coding mode corresponding to at least one semi-static scheduling configuration;

[0055] a channel coding mode corresponding to the first transport block, and the number of bits of the first transport block is less than the first threshold and greater than the second threshold;

[0056] A channel coding mode corresponding to the first downlink control channel;

[0057] S220: The controlled device receives the configuration information sent by the control device.

[0058] The embodiments of the present application can be applied to Figure 1 A burst interference system 100 is shown.

[0059] In the embodiment of the present application, uplink refers to a link in which the controlled device is the transmitting end and the controlling device is the receiving end; downlink refers to a link in which the controlled device is the receiving end and the controlling device is the transmitting end.

[0060] In the embodiment of the present application, further, the controlled device can determine the corresponding channel coding method based on the configuration information.

[0061] Optionally, in the embodiment of the present application, the channel coding method includes at least one of the following:

[0062] Polar coding, LDPC coding, Reed-Solomon (RS) coding.

[0063] Optionally, in an embodiment of the present application, the first threshold and the second threshold are preconfigured or agreed upon by protocol, or the first threshold and the second threshold are determined by the control device.

[0064] For example, the number of bits of the first transmission block is 32.

[0065] In an embodiment of the present application, the at least one semi-static scheduling configuration may be part or all of the semi-static scheduling configuration configured by the control device to the controlled device. The first transmission block may be a transmission block on an uplink data channel, or the first transmission block may be a transmission block on a downlink data channel.

[0066] In an embodiment of the present application, a semi-static scheduling configuration is used to configure semi-static scheduling resources. The transmitting device can encode the physical channel sent on the semi-static scheduling resources based on the channel coding method corresponding to the semi-static scheduling configuration, and the receiving device can decode the physical channel received on the semi-static scheduling resources based on the channel coding method corresponding to the semi-static scheduling configuration.

[0067] For example, the control device configures the first semi-static scheduling configuration to correspond to the first encoding mode, and configures the second semi-static scheduling configuration to correspond to the second encoding mode. If the semi-static configuration signaling does not include the encoding mode configuration, it means that the current semi-static scheduling configuration corresponds to the default encoding mode or the default encoding mode.

[0068] Optionally, in an embodiment of the present application, the control device determines the configuration information based on the first information, or the configuration information is determined based on the first information.

[0069] Optionally, in an embodiment of the present application, the control device may further determine the configuration information based on the first information and the first corresponding relationship, or, further, the configuration information may be determined based on the first information and the first corresponding relationship.

[0070] The first information includes at least one of the following:

[0071] The current time, the geographical location of the controlling device, the geographical location of the controlled device, and the channel interference situation.

[0072] It should be noted that the current time may be the time when the control device determines the configuration information.

[0073] Optionally, the channel interference situation is obtained by detecting the receiving power on at least one subcarrier.

[0074] For example, the control device obtains the channel interference situation by detecting the receiving power on at least one subcarrier.

[0075] For another example, the controlled device obtains the channel interference condition by detecting the receiving power on at least one subcarrier.

[0076] Optionally, the at least one subcarrier is selected by the control device or the controlled device according to its own implementation mode, or is randomly selected by the control device or the controlled device.

[0077] The first corresponding relationship includes at least one of the following:

[0078] The correspondence between time information and channel coding method, the correspondence between the geographical location of the control device and the channel coding method, the relationship between time information and the geographical location of the control device and the channel coding method, the correspondence between the geographical location of the controlled device and the channel coding method, and the correspondence between the channel interference situation and the channel coding method.

[0079] Optionally, the first corresponding relationship is determined based on pre-configuration information. For example, the control device determines the first corresponding relationship according to the pre-configuration information.

[0080] Optionally, the control device determines or updates the first corresponding relationship according to a channel interference situation. Alternatively, the first corresponding relationship is determined or updated based on the channel interference situation.

[0081] For example, the control device determines based on the pre-configuration information that all geographical areas where the control device is located use polarization coding. If the control device detects in a certain geographical area that the received power on one or several subcarriers is higher than the received power X1 of the subcarrier where the uplink reference signal is located, the control device updates the coding method corresponding to the geographical area to RS coding.

[0082] Optionally, in an embodiment of the present application, when the first information changes, the control device sends a dynamic signaling to the controlled device, where the dynamic signaling is used to instruct the controlled device to change the channel coding mode configured by the configuration information.

[0083] Correspondingly, the controlled device receives the dynamic signaling sent by the control device when the first information changes, and the dynamic signaling is used to instruct the controlled device to change the channel coding mode configured by the configuration information.

[0084] Optionally, the dynamic signaling is also used to schedule downlink transmission or uplink transmission, and the changed channel coding mode indicated by the dynamic signaling is only valid for the downlink transmission or uplink transmission scheduled by the dynamic signaling.

[0085] Optionally, the changed channel coding mode indicated by the dynamic signaling is only valid for a downlink control channel sent within a radio frame.

[0086] Optionally, the dynamic signaling is carried in a downlink control channel, or the dynamic signaling is carried in a broadcast channel.

[0087] It should be noted that in the embodiment of the present application, the uplink data channel is similar to the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) in a cellular network, the uplink control channel is similar to the physical uplink control channel (Physical Uplink Control Channel, PUCCH) in a cellular network, the downlink data channel is similar to the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) in a cellular network, the downlink control channel is similar to the physical downlink control channel (Physical Downlink Control Channel, PDCCH) in a cellular network, and the broadcast channel is similar to the physical layer broadcast channel (Physical Broadcast Channel, PBCH) in a cellular network.

[0088] The channel coding scheme of the present application is described in detail below through Examples 1 to 3.

[0089] In embodiment 1, the configuration information is used to configure a channel coding method corresponding to the at least one semi-static scheduling configuration.

[0090] In Embodiment 1, the configuration information is semi-static configuration information. For example, the control device configures one or more semi-static scheduling configurations for the controlled node through Radio Resource Control (RRC) signaling, and the control device can configure the coding method used for the semi-static scheduling resources configured by the one or more semi-static scheduling configurations.

[0091] In Embodiment 1, the semi-static scheduling configuration without configuring a channel coding mode corresponds to a default coding mode or a default coding mode.

[0092] Optionally, in Example 1,

[0093] For a device that transmits according to the semi-persistent scheduling configuration in the at least one semi-persistent scheduling configuration, encoding a physical channel to be transmitted using a corresponding encoding method; and / or,

[0094] For a device that receives according to the semi-persistent scheduling configuration in the at least one semi-persistent scheduling configuration, a corresponding encoding method is used to decode the received physical channel.

[0095] Optionally, the physical channel is an uplink data channel or a downlink data channel.

[0096] Optionally, in Embodiment 1, the control device may determine the encoding method to be used according to its current geographical location, and adjust the encoding method as the geographical location changes. For example, if the current location of the control device is a first geographical area, the control device configures the encoding method corresponding to a semi-static scheduling configuration as a first encoding method, and when the control device enters a second geographical area, the encoding method corresponding to the semi-static scheduling configuration is configured as a second encoding method through RRC signaling.

[0097] Optionally, in Embodiment 1, the control device may determine the encoding method to be used according to its current time, and adjust the encoding method over time. For example, if the current time is a first time period, the control device configures the encoding method corresponding to a semi-static scheduling configuration as a first encoding method, and after exceeding the first time period, configures the encoding method corresponding to the semi-static scheduling configuration as a second encoding method through RRC signaling.

[0098] Optionally, in Embodiment 1, the control device may determine the encoding method to be used according to its current time and current location, and adjust the encoding method as time passes or the location changes. For example, if the current time is a first time period and the current location is a first geographical area, the control device configures the encoding method corresponding to a semi-static scheduling configuration as a first encoding method, and conversely, configures the encoding method corresponding to the semi-static scheduling configuration as a second encoding method through RRC signaling.

[0099] Optionally, in Embodiment 1, the control device may change the encoding method adopted by the semi-static scheduling configuration through dynamic signaling, such as dynamic signaling carried by a downlink control channel. For example, the control device may configure the encoding method corresponding to a semi-static scheduling configuration as a first encoding method, and when certain conditions are met, indicate the corresponding encoding method as a second encoding method through a downlink control channel. In this case, if the semi-static resources configured by the semi-static scheduling configuration are used for downlink data transmission, the control device adopts the second encoding method to send the downlink data channel, and for the controlled device, the downlink channel should be received and decoded according to the second encoding method; if the semi-static scheduling configuration configured by the semi-static scheduling configuration is used for uplink data transmission, the controlled device should adopt the second encoding method to send the uplink data channel, and the control device receives the uplink channel according to the second encoding method and decodes it.

[0100] Optionally, in Example 1, the coding method changed by dynamic signaling is only valid for the downlink transmission or uplink transmission indicated by the dynamic signaling. In the absence of dynamic signaling indication, the uplink or downlink transmission adopts the coding method corresponding to the semi-static scheduling configuration.

[0101] Optionally, in Example 1, the control device may also select a coding method to be used according to the currently measured channel interference situation. For example, when the control device detects that the received power on one or several subcarriers is higher than the received power X1 of the subcarrier where the uplink reference signal is located, the control device reconfigures the coding method corresponding to a semi-static scheduling configuration using the first coding method to a second coding method. The first coding method may be a polarization code, and the second coding method may be an RS code.

[0102] In embodiment 2, the configuration information is used to configure a channel coding method corresponding to the first transmission block.

[0103] In embodiment 2, the configuration information is semi-static configuration information, or the configuration information is dynamic configuration information.

[0104] Optionally, in Embodiment 2, for the device that sends the first transmission block, the first transmission block is encoded using the encoding method corresponding to the first transmission block; and / or, for the device that receives the first transmission block, the first transmission block is decoded using the encoding method corresponding to the first transmission block.

[0105] Optionally, in Embodiment 2, for dynamically scheduled downlink or uplink transmission, i.e., the first transmission block, if the number of bits of the first transmission block is less than the first threshold and greater than the second threshold, the dynamic scheduling signaling carries a specific information field indicating the encoding method corresponding to the first transmission block. Alternatively, the control device indicates the encoding method corresponding to the first transmission block through semi-static signaling, such as RRC signaling. Preferably, in Embodiment 2, the control device selects or determines the encoding method corresponding to the first transmission block according to the currently measured channel interference situation. For example, when the control device detects that the received power on one or several subcarriers is higher than the received power X2 of the subcarrier where the uplink reference signal is located, the control device indicates the encoding method corresponding to the first transmission block as the first encoding method (e.g., RS code) through dynamic signaling or semi-static signaling. Otherwise, the control device indicates the encoding method corresponding to the first transmission block as the second encoding method (e.g., polarization code) through dynamic signaling or semi-static signaling. The control device may also determine the encoding method to be used according to its current geographical location, and adjust the encoding method as the geographical location changes. For example, if the control device is currently located in the first geographical area, the control device indicates the encoding method corresponding to the first transmission block as the first encoding method, and when the control device enters the second geographical area, the encoding method corresponding to the first transmission block is indicated as the second encoding method. The control device can also determine the encoding method to be used according to its current time and current location, and adjust the encoding method as time passes or the location changes.

[0106] Optionally, in Embodiment 2, the control device indicates the coding mode corresponding to the first transmission block through semi-static signaling, such as RRC signaling, and when certain conditions are met, the coding mode corresponding to the first transmission block can be changed by dynamic signaling. For example, the control device can configure the coding mode corresponding to the first transmission block as the first coding mode through semi-static signaling, and when certain conditions are met, indicate the coding mode corresponding to the first transmission block as the second coding mode through the downlink control channel. Preferably, the control device selects or determines the coding mode corresponding to the first transmission block according to the currently measured channel interference situation. For example, the control device can configure the coding mode corresponding to the first transmission block as the first coding mode through semi-static signaling. When the control device detects that the received power on one or several subcarriers is higher than the received power X2 of the subcarrier where the uplink reference signal is located, the control device reconfigures the coding mode corresponding to the first transmission block to the second coding mode, wherein the first coding mode may be a polarization code, and the second coding mode may be an RS code. In this case, the transmitting end uses the second coding mode to send the data channel, and the receiving end should receive and decode the downlink channel according to the second coding mode.

[0107] Optionally, in Embodiment 2, the coding method changed by dynamic signaling is only valid for downlink transmission or uplink transmission indicated by the dynamic signaling. In the absence of dynamic signaling indication, uplink or downlink transmission adopts the coding method indicated by semi-static signaling.

[0108] In embodiment 3, the configuration information is used to configure a channel coding method corresponding to the first downlink control channel.

[0109] In embodiment 3, the configuration information is semi-static configuration information, or the configuration information is dynamic configuration information.

[0110] Optionally, in Embodiment 3, when the configuration information is semi-static configuration information, the configuration information is used to configure a coding method corresponding to the first downlink control channel, for example, only polarization coding, RS coding, or LDPC coding is used.

[0111] Optionally, in Embodiment 3, when the configuration information is dynamic configuration information, the configuration information is used to configure multiple channel coding modes corresponding to the first downlink control channel.

[0112] Optionally, in Example 3, for the device that sends the first downlink control channel, the first downlink control channel is encoded using one of the multiple channel coding methods; and / or, for the device that receives the first downlink control channel, the multiple channel coding methods are used to blindly detect the first downlink control channel.

[0113] Optionally, in Embodiment 3, when the configuration information is used to configure multiple channel coding modes corresponding to the first downlink control channel, the control device indicates the multiple channel coding modes corresponding to the first downlink control channel through a system message, and the sending resources and sending modes of the broadcast channel do not need to be indicated through the downlink control channel. For example, the control device may indicate the channel coding mode corresponding to the first downlink control channel as a polarization code or an RS code, or the control device may indicate the channel coding mode corresponding to the first downlink control channel as a polarization code or an RS code through the broadcast message according to its geographical location, and after the geographical location changes, the channel coding mode corresponding to the first downlink control channel is converted to an RS code or a polarization code.

[0114] Optionally, in Embodiment 3, when the configuration information is used to configure multiple channel coding modes corresponding to the first downlink control channel, the receiving end assumes blind detection of the first downlink control channel according to different channel coding modes. For example, the first downlink control channel may use polarization codes and RS codes, and the control device indicates the channel coding mode corresponding to the first downlink control channel to the controlled device through a system message, and the sending resources and sending mode of the broadcast channel do not need to be indicated through the downlink control channel. For example, the control device may indicate the channel coding mode corresponding to the first downlink control channel as a polarization code or an RS code, and the control device selects the polarization code or the RS code to send the first downlink control channel according to the channel interference situation, and the receiving end decodes the first downlink control channel based on two different codes.

[0115] Optionally, in Example 3, preferably, within one wireless frame, the control device uses only one channel coding method to send the first downlink control channel. When the control device detects that the received power on one or several subcarriers is higher than the received power X3 of the subcarrier where the uplink reference signal is located, the control device uses RS coding to send the first downlink control channel, otherwise it uses polarization coding to send the first downlink control channel.

[0116] Optionally, in Embodiment 3, preferably, the controlled node first decodes the downlink control channel based on coding mode A. If at least one downlink control channel is successfully detected, the controlled terminal detects other possible downlink control channels only based on coding mode A. Otherwise, the controlled terminal re-detects the downlink control channel based on coding mode B. Coding mode A and coding mode B may be configured by a system message or defined by a standard. For example, the standard defines coding mode A as a polar code and defines coding mode B as an RS code.

[0117] Therefore, in an embodiment of the present application, the control device may configure a channel coding method corresponding to at least one semi-static scheduling configuration; or, the control device may configure a channel coding method corresponding to a first transmission block, and the number of bits of the first transmission block is less than a first threshold value and greater than a second threshold value; or, the control device may configure a channel coding method corresponding to a first downlink control channel. Thus, channel coding in a burst interference system can be achieved.
