[0033] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.

[0034] Unless otherwise required by context, as used herein and throughout this specification, the term "comprise" and variations of the term, such as "comprises" and "comprising," will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. In describing the disclosure, specific terminology will be used to describe particular features, structures, materials or characteristics. It is to be understood that the terminology is used only in a descriptive sense and not for the purpose of limiting the disclosure. Unless otherwise required by context, the use herein and throughout this specification of the singular includes the plural. The use herein and throughout this specification of "or" means "and / or" unless otherwise stated.

[0035] The terms "first", "second", and the like, are used only to describe a particular aspect and do not imply either a relative importance or a specific order. Thus, a feature defined by "first", "second", and the like, can include one or more of the features implicitly or explicitly. In the description of the disclosure, the meaning of "a plurality of" is two or more unless otherwise stated.

[0036] In the embodiments of the present disclosure, the words "exemplary" and "for example" are used to describe examples, embodiments or implementations. Any embodiment or design scheme described by "exemplary" and "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or having more advantages than other embodiments or design schemes. Rather, the use of "exemplary" and "for example" is intended to present the relevant concept in a specific manner.

[0037] In addition, the use of "based on" means open and inclusive, as the process, step, calculation or other action based on one or more stated conditions or values can be based on additional conditions or values beyond those stated in practice.

[0038] Taking channel state information transmission as an example, in a mobile communication system, a base station informs a terminal through downlink control information carried by a physical downlink control channel that the terminal needs to send channel state information to the base station. The terminal obtains channel state information based on measurement and processing of channel state information reference signals, and sends the channel state information to the base station using resources allocated in the downlink control information. At this time, the channel state information and the terminal's uplink data can be sent to the base station by multiplexing.

[0039] In the related art, the terminal transmits channel state information to the base station in a relatively conservative fixed modulation and coding mode. The amount of information carried by the channel state information does not change with the change of the uplink channel between the terminal and the base station, and the flexibility is poor. For example, in the related art, regardless of the quality of the uplink channel, assuming that the rank of the terminal is 1, the number of bits of the channel state information transmission is fixed as X bits, and even if the quality of the uplink channel is very good, more accurate channel state information cannot be transmitted to the base station through more bits, and the flexibility is very poor. Therefore, how to improve the flexibility of information transmission is a problem to be solved.

[0040] Based on this, the embodiments of the present disclosure provide an information sending and receiving method, device, storage medium and program product. A first node processes first information based on at least one of a first field, a first adjustment field and a first input quantity to obtain second information, so that the amount of information carried by the second information can match the current channel capacity, and then sends the second information to a second node. Compared with the fixed coding and modulation mode for transmitting information to the second node in the related art, the flexibility of information transmission is improved.

[0041] The scheme of the embodiments of the present disclosure will be described below with reference to the drawings.

[0042] The technical scheme provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, NR (new radio) mobile communication networks using the 5th generation mobile communication technology (5th generation mobile networks, 5G), future mobile communication networks (for example, 6G wireless communication system) or various communication fusion systems, etc. The embodiments of the present disclosure do not limit this.

[0043] In the embodiments of the present disclosure, the mobile communication network (including but not limited to the third generation 3G, the fourth generation 4G, the fifth generation 5G and the future mobile communication network, such as the sixth generation mobile communication network 6G) can include a network side device (for example, including but not limited to a base station) and a receiving side device (for example, including but not limited to a terminal). And it should be understood that in the present example, such as in the downlink, the first communication node (also can be called first communication node device, first node) can be a base station side device, and the second communication node (also can be called second communication node device, second node) can be a terminal side device. In some examples, such as in the uplink, the first communication node can also be a terminal side device, and the second communication node can also be a base station side device. In some examples, such as in device-to-device communication between two communication nodes, the first communication node and the second communication node can both be base stations or terminals. Therefore, whether the first node and the second node are base stations or terminals needs to be determined according to the context.

[0049] It should be understood that FIG. 1 is an exemplary structural diagram, and the number of devices included in the communication system shown in FIG. 1 is not limited, for example, the number of first nodes and the number of second nodes are not limited. In addition, the communication system shown in FIG. 1 can include other devices in addition to the devices shown in FIG. 2, which is not limited.

[0050] Next, as shown in FIG. 2, the embodiment of the disclosure provides an information sending method, applied to a first node, which can be the first node 110 shown in FIG. 1. The information sending method can include the following: S101-S103.

[0051] In S101, first information is acquired.

[0052] The first information is information related to a channel state. For example, the first information is channel state information.

[0053] Taking the first information as the channel state information for example, the first node acquires the first information, which can be that the first node receives a channel state information reference signal and then measures the channel state information reference signal to obtain the first information. For example, as shown in FIG. 3, it is an information processing flow diagram according to the embodiment of the disclosure. Referring to FIG. 3, the first node can perform linear processing (for example, matrix related operation) or nonlinear processing (for example, neural network, which can be an encoder in an autoencoder) on the channel measurement result obtained by measuring the channel state information reference signal to obtain the first information.

[0054] For ease of description, the following embodiments take the first node as a terminal and the second node as a base station for example. The second node can be the second node 120 in the communication system shown in FIG. 1.

[0055] In S102, the first information is processed based on at least one of the first field, the first adjustment field, and the first input quantity to obtain second information.

[0056] In some embodiments, the first field is used to indicate an index value of a modulation and coding scheme (MCS). The first field is used to indicate an adjustment value, which is used to adjust the index value of the modulation and coding scheme indicated by the first field. The first input quantity is used to represent channel transmission quality, which is the channel transmission quality of the channel between the first node and the second node.

[0057] In some embodiments, the number of elements contained in the second information is determined by at least one of the first field, the first adjustment field, and the first input quantity. For example, the number of elements contained in the second information is determined by the first field and the first adjustment field, or is determined by the first input quantity.

[0058] In some embodiments, the first input quantity is obtained by the first node predicting uplink reception quality, or the first input quantity is obtained by the first node processing the uplink reception quality information provided by the second node to the first node and the relevant information collected by the first node.

[0059] As an example, taking processing the first information based on the first field and the first adjustment field to obtain the second information as an example, the first field indicated modulation coding scheme index value and the first adjustment field indicated adjustment value can be processed to obtain the processed index value, and then the first information is processed based on the processed index value to obtain the second information. That is, the first field indicated modulation coding scheme index value is adjusted based on the first adjustment field indicated adjustment value to obtain the processed modulation coding scheme index value, and then the first information is processed based on the processed modulation coding scheme index value to obtain the second information.

[0060] It should be understood that, compared with the related art that transmits information with a fixed modulation coding scheme, the amount of transmitted information cannot be matched with the current channel capacity, and the embodiment of the present disclosure proposes processing the first field indicated modulation coding scheme index value and the first adjustment field indicated adjustment value to obtain the processed index value, and then processing the first information based on the processed index value to obtain the second information, that is, introducing the first adjustment field to adjust the first field indicated modulation coding scheme index value, so that the adjusted modulation coding scheme index value can be matched with the current channel transmission quality. The channel transmission quality is related to the channel capacity, that is, the second information obtained by processing the first information based on the first field and the first adjustment field can be matched with the current channel capacity. In this way, compared with the related art that transmits information with a fixed modulation coding scheme, the index value of the modulation coding scheme can be flexibly adjusted based on the first adjustment field, thereby improving the flexibility of information transmission.

[0061] Processing the first field indicated modulation coding scheme index value and the first adjustment field indicated adjustment value can be arithmetic processing of the first field indicated modulation coding scheme index value and the first adjustment field indicated adjustment value. The arithmetic processing includes addition processing, subtraction processing, multiplication processing, division processing, etc. For example, the first field indicated modulation coding scheme index value and the first adjustment field indicated adjustment value are added or subtracted to obtain the index value after addition or subtraction processing, and then the first information is processed based on the index value after addition or subtraction processing to obtain the second information.

[0062] In some embodiments, the processed index value is used to represent the uplink channel transmission quality value. As an example, as shown in FIG. 4, another information processing flow diagram according to an embodiment of the present disclosure is shown. Referring to FIG. 4, the first node takes the uplink channel transmission quality value as one of the inputs of the processing algorithm to process the first information to obtain the second information.

[0063] In some embodiments, the first field is used to describe a modulation and coding scheme, and the first adjustment field is used to indicate an adjustment value.

[0064] As another example, taking processing the first information based on the first field and the first adjustment field to obtain the second information as an example, the modulation and coding scheme described by the first field and the adjustment value indicated by the first adjustment field can be taken as input parameters of artificial intelligence (AI) and input into the AI, and then the first information is processed based on the AI to obtain the second information. That is, the modulation and coding scheme described by the first field, the adjustment value indicated by the first adjustment field, and the first information are input into the AI to obtain the second information. For how to input the modulation and coding scheme described by the first field, the adjustment value indicated by the first adjustment field, and the first information into the AI to obtain the second information, reference can be made to the description in the related art, and the embodiments of the present disclosure are not limited thereto.

[0065] In some embodiments, the first field and the first adjustment field are contained in the same signaling, or are contained in different signaling. For example, the first field and the first adjustment field are contained in the first signaling, or the first field is contained in the first signaling and the first adjustment field is contained in the second signaling.

[0066] Taking the first field and the first adjustment field being contained in the first signaling as an example, processing the index value of the modulation and coding scheme indicated by the first field and the adjustment value indicated by the first adjustment field to obtain a processed value can be processing the index value of the modulation and coding scheme indicated by the first field in the first signaling and the adjustment value indicated by the first adjustment field in the first signaling to obtain the processed value.

[0067] Taking the first field being contained in the first signaling and the first adjustment field being contained in the second signaling as an example, processing the index value of the modulation and coding scheme indicated by the first field and the adjustment value indicated by the first adjustment field to obtain a processed value can be processing the index value of the modulation and coding scheme indicated by the first field in the first signaling and the adjustment value indicated by the first adjustment field in the second signaling to obtain the processed value.

[0068] In some embodiments, the first signaling is downlink control information carried by a physical downlink control channel, and the second signaling is medium access control signaling or radio resource control signaling carried by a physical downlink data channel. The first signaling and the second signaling can be transmitted by the second node and received by the first node before the first node obtains the first information.

[0069] As another example, taking the example of processing the first information based on the first input quantity to obtain the second information, the first information can be processed based on the first field to obtain the second information in the case that the physical data channel configured by the first signaling does not need to transmit data services. The first signaling is signaling containing the first field, and the physical data channel includes a physical uplink data channel.

[0070] Exemplarily, the first signaling carries a specific field, and the specific field is used to indicate that the physical data channel configured by the first signaling does not need to transmit uplink service data.

[0071] It should be understood that, in the related art, information is transmitted by using a fixed modulation and coding scheme, and the amount of transmitted information cannot be matched with the current channel capacity. The embodiment of the present disclosure proposes processing the first information based on the first input quantity to obtain the second information. Since the first input quantity is obtained by the first node based on the uplink reception quality, the amount of information carried by the second information obtained by processing the first information based on the first input quantity can be matched with the current channel transmission quality. The channel transmission quality is related to the channel capacity, that is, the amount of information carried by the second information is matched with the current channel capacity, so that the amount of information carried by the second information can change due to the change of the channel between the first node and the second node, thereby improving the flexibility of information transmission.

[0072] In some embodiments, processing the first information includes linear processing or nonlinear processing of the first information, that is, the processing includes linear processing or nonlinear processing.

[0073] For example, referring to FIG. 5, which is another information processing flow diagram according to an embodiment of the present disclosure, the first information and the uplink channel transmission quality value can be linearly processed (for example, matrix-related operation) or nonlinearly processed (for example, neural network, which can be an encoder in an autoencoder) to obtain the second information. The second information can be a bit sequence, or a set of real numbers, or a set of complex numbers.

[0074] It should be noted that the length of the bit sequence, the number of the set of real numbers, and the number of the set of complex numbers can be pre-negotiated by the first node and the second node, or determined by the first node based on at least the content of the first field and / or the content of the first adjustment field, for example, when the uplink channel quality is good, the length of the bit sequence, the number of the set of real numbers, and the number of the set of complex numbers can be larger; when the channel quality is poor, the length of the bit sequence, the number of the set of real numbers, and the number of the set of complex numbers can be smaller.

[0075] For another example, referring to FIG. 6, which is a schematic diagram of another information processing flow according to an embodiment of the present disclosure, the first input quantity and the first information can be processed linearly (for example, a matrix operation) or nonlinearly (for example, a neural network, which can be an encoder in an autoencoder) to obtain the second information.

[0076] In some embodiments, the number of bits of the first adjustment field and / or the adjustment value indicated by the first adjustment field is pre-negotiated or configured by default between the first node and the second node. For example, the first adjustment field is 2 bits, representing four indexes, and the bit sequence 00 / 01 / 10 / 11 can be configured to correspond to four adjustment values 1 / 3 / 5 / 7 or 2 / 4 / 6 / 8, respectively. The second node can negotiate the adjustment values corresponding to the bit sequence with the first node according to the actual situation of the uplink of the entire communication system.

[0077] In some embodiments, the first signaling containing the first field further contains a field for indicating whether the second information is transmitted, or the first adjustment field is further used for indicating whether the second information is transmitted. As an example, a specific value of the first adjustment field is used to indicate that the second information is not transmitted, for example, the bit 00 in the first adjustment field represents that the second information does not need to be transmitted. At this time, the first node can not measure the channel state information reference signal, and does not need to obtain the first information or process the first information to obtain the second information.

[0078] In some embodiments, the first field is used to indicate a modulation and coding scheme of a physical data channel configured by the first signaling containing the first field.

[0079] In some embodiments, the value of the first adjustment field is determined based on the value of the first field. That is, the value of the first field determines the value of the first adjustment field. For example, the value of the first adjustment field is 01, and when the value of the first field is 0111, corresponding to the 8th level of the MCS, the value 01 of the first adjustment field means 3 levels, and one of the input quantities of the algorithm for generating the second information is (8-3) = 5, which is used to describe the channel quality of the transmission channel state information. For another example, the value of the first adjustment field is still 01, and when the value of the first field is 1110, corresponding to the 15th level of the MCS, the value 01 of the first adjustment field means 1 level, and one of the input quantities of the algorithm for generating the second information is (15-1) = 14, which is used to describe the channel quality of the transmission channel state information. The association relationship can be realized in the form of a table.

[0080] In S103, the second information is transmitted to the second node.

[0081] Based on the embodiment shown in FIG. 2, compared with transmitting information in a fixed modulation coding scheme in the related art, the embodiment of the present disclosure proposes processing the first information based on at least one of the first field, the first adjustment field, and the first input quantity to obtain second information, so that the information quantity carried by the second information can be matched with the current channel capacity, that is, the information quantity carried by the second information can change due to the change of the channel between the first node and the second node, and then the second information is transmitted to the second node, thereby improving the flexibility of information transmission and helping to improve the efficiency of information transmission.

[0082] In some embodiments, after the first node transmits the second information to the second node, the first node can process the second information to obtain third information, and then transmit the third information to the second node. The third information is used by the second node to determine the reception quality of the second information.

[0083] As an example, the first node processes all or part of the content in the second information according to a scheme pre-negotiated by the first node and the second node or a default configuration to obtain third information, and transmits the third information to the second node. In this way, when the second node cannot determine the reception quality of the second information, the reception quality of the second information can be determined through the reception quality of the third information.

[0084] In some embodiments, the third information includes a check bit. The check bit is used by the second node to determine the reception of the third information through the check bit.

[0085] In some embodiments, in the case where the first node processes the first information based on the first output quantity to obtain the second information, the first node transmits the first input quantity to the second node, so that the second node can reconstruct the second information based on the first input quantity after receiving the second information.

[0086] In some embodiments, as shown in FIG. 7, the embodiment of the present disclosure provides an information receiving method, which is applied to a second node. The information receiving method can include the following: S201, receiving second information transmitted by a first node.

[0087] The second information is obtained by processing the first information based on at least one of the first field, the first adjustment field, and the first input quantity. For the description of the first field, the first adjustment field, and the first input quantity, reference can be made to the corresponding description in the above-described embodiment shown in FIG. 2, which will not be repeated here.

[0088] In some embodiments, the first field is used to indicate an index value of a modulation and coding scheme, and the first adjustment field is used to indicate an adjustment value, which is used to adjust the index value of the modulation and coding scheme indicated by the first field. The second information is obtained by processing the first information based on a processed index value, which is obtained by processing the index value of the modulation and coding scheme indicated by the first field and the adjustment value indicated by the first adjustment field.

[0089] In some embodiments, the first field is used to describe a modulation and coding scheme, and the first adjustment field is used to indicate an adjustment value, which is used to adjust the modulation and coding scheme described by the first field to obtain an adjustment result. The second information is obtained by processing the first information based on the adjustment result, and the processed index value is obtained by processing the index value of the modulation and coding scheme indicated by the first field and the adjustment value indicated by the first adjustment field.

[0090] In some embodiments, the second information is obtained by processing the first information based on the first field without transmitting data service on the physical data channel configured by the first signaling. The first signaling is a signaling containing the first field.

[0091] In some embodiments, the number of bits of the first adjustment field and / or the adjustment value indicated by the first adjustment field is pre-negotiated or default-configured by the first node and the second node.

[0092] In some embodiments, the first signaling containing the first field further contains a field used to indicate whether the second information is transmitted, or the first adjustment field is further used to indicate whether the second information is transmitted.

[0093] In some embodiments, the processing includes linear processing or non-linear processing.

[0094] In some embodiments, the first field is used to indicate a modulation and coding scheme of a physical data channel configured by the first signaling containing the first field.

[0095] In some embodiments, the first field and the first adjustment field are contained in the first signaling, or the first field is contained in the first signaling and the first adjustment field is contained in the second signaling. The first signaling is downlink control information carried by a physical downlink control channel, and the second signaling is medium access control signaling or radio resource control signaling carried by a physical downlink data channel.

[0096] In some embodiments, the second node receives third information transmitted by the first node, the third information is obtained by processing the second information, and the third information is used by the second node to determine the reception quality of the second information.

[0097] In some embodiments, the third information comprises a check bit, and the check bit is used by the second node to determine the reception of the third information.

[0098] In some embodiments, the value of the first adjustment field is determined based on the value of the first field.

[0099] In some embodiments, the first information is information related to a channel state.

[0100] In some embodiments, the second node receives a first input quantity transmitted by the first node. The first input quantity is used to reconstruct the channel.

[0101] As shown in FIG. 8, it is a schematic diagram of information reconstruction according to an embodiment of the present disclosure. After the second node receives the first input quantity, the second node needs to use the first input quantity as the input of the reconstruction algorithm when reconstructing the channel using the second information. The reconstruction algorithm includes linear processing or nonlinear processing (for example, a neural network).

[0102] The channel is dynamically changing, and therefore, the mobile communication system needs to adjust the transmission power of the information according to the dynamically changing channel. However, in the related art, a relatively fixed transmission power is used to transmit the information, which causes the transmission power of the information to be unable to match the current channel environment, resulting in a high energy consumption of the information transmission. How to reduce the energy consumption of the information transmission is a problem to be solved. Based on this, as shown in FIG. 9, an embodiment of the present disclosure provides an information transmission method applied to a first node. The first node can be the first node 110 in the communication system shown in FIG. 1. The information transmission method can comprise the following S301 to S303.

[0103] In S301, fourth information is obtained.

[0104] The fourth information is information related to a channel state. For example, the fourth information is channel state information.

[0105] Taking the fourth information as the channel state information as an example, the first node obtaining the fourth information can be that the first node receives a channel state information reference signal and then measures the channel state information reference signal to obtain the fourth information.

[0106] In S302, the transmission power of the fourth information is determined based on a transmission power control field and a second adjustment field.

[0107] In some embodiments, the transmission power control field is used to indicate a power control adjustment amount, and the second adjustment field is used to indicate an adjustment value. The adjustment value is used to adjust the power control adjustment amount indicated by the transmission power control field.

[0108] As an example, determining the transmission power of the fourth information based on the transmission power control field and the second adjustment field can be processing the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field to obtain a processed power control adjustment amount, and then determining the transmission power of the fourth information according to the processed power control adjustment amount.

[0109] As another example, determining the transmission power of the fourth information based on the transmission power control field and the second adjustment field can be determining the transmission power of the fourth information according to the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field. For example, taking the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field as input parameters of the AI to obtain the transmission power of the fourth information. That is, inputting the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field into the AI to obtain the transmission power of the fourth information. For how to input the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field into the AI to obtain the transmission power of the fourth information, descriptions can be referred to in the related art, and the embodiments of the present disclosure are not limited thereto.

[0110] Processing the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field can be performing arithmetic processing on the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field. The arithmetic processing includes addition processing, subtraction processing, multiplication processing, division processing, etc. For example, performing addition processing or subtraction processing on the power control adjustment amount indicated by the transmission power control field and the adjustment value indicated by the second adjustment field to obtain a power control adjustment amount after addition processing or subtraction processing, and then determining the transmission power of the fourth information based on the power control adjustment amount after addition processing or subtraction processing.

[0111] In some embodiments, the processed power control adjustment amount can be used in a power control formula, or a result obtained by jointly calculating the processed power control adjustment amount and a power adjustment step size is used in the power control formula to obtain the transmission power of the fourth information. For how to obtain the transmission power of the fourth information based on the power control formula and the processed power control adjustment amount, descriptions can be referred to in the related art, and will not be repeated here.

[0112] In some embodiments, the transmission power control field and the second adjustment field are obtained by the first node from the second node before obtaining the fourth information.

[0113] In some embodiments, the number of bits of the second adjustment field and / or the adjustment value indicated by the second adjustment field is pre-negotiated or configured by default between the first node and the second node.

[0114] For example, the second adjustment field is 2 bits, indicating four indexes. The bit sequence of 00 / 01 / 10 / 11 can be configured to correspond to four adjustment values of 1 / 3 / 5 / 7 or 2 / 4 / 6 / 8 respectively. The second node can negotiate with the first node the adjustment values corresponding to the bit sequence according to the actual situation of the uplink of the entire communication system.

[0115] In some embodiments, the transmission power control field is also used to determine the transmission power of the physical data channel configured by the third signaling containing the transmission power control field.

[0116] In some embodiments, the transmission power control field and the second adjustment field are contained in the third signaling, or the transmission power control field is contained in the third signaling and the second adjustment field is contained in the fourth signaling. The third signaling is the downlink control information carried by the physical downlink control channel, and the fourth signaling is the medium access control signaling or the radio resource control signaling carried by the physical downlink data channel.

[0117] For example, the transmission power control field and the second adjustment field are contained in the third signaling. The transmission power of the fourth information determined based on the transmission power control field and the second adjustment field can be determined based on the transmission power control field and the second adjustment field in the third signaling.

[0118] For example, the transmission power control field is contained in the second signaling and the second adjustment field is contained in the fourth signaling. The transmission power of the fourth information determined based on the transmission power control field and the second adjustment field can be determined based on the transmission power control field in the third signaling and the second adjustment field in the fourth signaling.

[0119] In some embodiments, the value of the second adjustment field is determined based on the value of the transmission power control field. That is, the value of the transmission power control field determines the value of the second adjustment field.

[0120] For example, when the second adjustment field takes the value of 01, and the transmission power control field takes the value of 0111, corresponding to the 8th level of power adjustment, the meaning of the second adjustment field taking the value of 01 is 3 levels, and one of the input quantities of the transmission power of the fourth information is determined as (8+3)=11, which is used to describe the transmission power adjustment quantity of the first information (the adjustment quantity can correspond to one or more variables in the power control formula). For another example, when the second adjustment field still takes the value of 01, and the transmission power control field takes the value of 1110, corresponding to the 15th level of power adjustment, the meaning of the second adjustment field taking the value of 01 is 1 level, and one of the input quantities of the transmission power of the fourth information is determined as (15+1)=16, which is used to describe the transmission power adjustment quantity of the fourth information.

[0121] In S303, the fourth information is sent to the second node based on the transmission power of the fourth information.

[0122] In some embodiments, after determining the transmission power of the fourth information, the first node sends the fourth information to the second node based on the transmission power of the fourth information.

[0123] Based on the embodiment shown in FIG. 9, compared with the related art in which information is transmitted at a relatively fixed transmission power, the embodiment of the present disclosure proposes to determine the transmission power of the fourth information based on the transmission power control field and the second adjustment field, that is, to adjust the transmission power adjustment quantity indicated by the transmission power control field based on the second adjustment field, and then to obtain the transmission power of the fourth information based on the adjusted transmission power adjustment quantity, and then to transmit the fourth information based on the transmission power of the fourth information. In this way, appropriate transmission power can be configured for the transmission of the fourth information, and the waste of energy can be avoided.

[0124] In some embodiments, as shown in FIG. 10, the embodiment of the present disclosure provides another information receiving method, which is applied to a second node. The second node can be the second node 120 in the communication system shown in FIG. 1.

[0125] The transmission power of the fourth information is determined based on the transmission power control field and the second adjustment field. For detailed description of the transmission power control field and the second adjustment field, reference can be made to the corresponding description in the embodiment shown in FIG. 9, which is not repeated here.

[0127] In some embodiments, the transmission power control field is used to indicate a power control adjustment amount, and the second adjustment field is used to indicate an adjustment value, and the adjustment value is used to adjust the power control adjustment amount indicated by the transmission power control field.
