Usually, the reference signal and the data channel are transmitted on different resource elements (REs) to avoid interference between the reference signal and the data channel.

[0003] However, as the number of antenna ports in a multiple-input-multiple-output (MIMO) system increases, the overhead of reference signals will increase and the spectrum efficiency of the system will decrease.

[0034] The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0037] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0038] In a MIMO wireless communication system, in order to further reduce the reference signal overhead, the reference signal and the data channel can be transmitted simultaneously on the same transmission resource, but this will also cause interference between the reference signal and the data channel received by the receiving end, causing the detection performance of the traditional detection algorithm to deteriorate.

[0039] Currently, the receiving end can use some nonlinear detection algorithm technologies to improve signal detection performance.

[0040] However, although the nonlinear detection algorithm can improve the signal detection performance of the receiving end, there is still interference between the reference signal and the data channel transmitted simultaneously on the same transmission resource in the MIMO wireless communication system, which will still affect the detection performance of the receiving end.

[0041] Therefore, how to transmit the reference signal and the data channel simultaneously on the same transmission resource to reduce the reference signal overhead has become a technical problem that needs to be solved urgently.

[0042] Based on this, in order to solve the above technical problems, the embodiment of the present disclosure provides a communication method, which is applied to the transmission scenario of the reference signal and the data channel of the MIMO wireless communication system. The transceiver node can transmit the reference signal and the data channel simultaneously on the same transmission resource according to the predetermined correlation relationship between the transmission power of the reference signal and the data channel. In this way, by obtaining the correlation relationship between the transmission power of the reference signal and the data channel, the receiving node can better design the receiving algorithm and reduce the interference between the reference signal and the data channel, so as to realize the simultaneous transmission of the reference signal and the data channel on the same transmission resource, thereby reducing the reference signal overhead.

[0043] The network architecture of the mobile communication network (including but not limited to 2G, 3G, 4G, 5G and future mobile communication networks (such as the future evolution of the fifth generation mobile communication technology (5th generation mobile communication technology advanced, 5G-A), the sixth generation mobile communication technology (6th generation mobile communication technology, 6G) and the seventh generation mobile communication technology (7th generation mobile communication technology, 7G))) in the embodiments of the present disclosure may include at least a first communication node and a second communication node, and the first communication node and the second communication node may be referred to as the first node and the second node, respectively.

[0044] For example, Figure 1 As shown, it is a schematic diagram of a communication system provided by an embodiment of the present disclosure, and the communication system may include: a first node 101 and a second node 102.

[0045] The second node 102 may predefine the association relationship between the transmission power of the reference signal and the data channel on the same time-frequency resource, and notify the first node 101 of the association relationship. Afterwards, the second node 102 may send the reference signal and the data channel to the first node 101 on the same transmission resource according to the association relationship.

[0046] The first node 101 can receive in advance the association relationship between the transmission power of the reference signal and the data channel on the same time-frequency resources defined by the second node 102, and receive the reference signal and data channel sent by the second node 102 on the same transmission resource according to the association relationship, and perform signal detection on the reference signal and the data channel in combination with the detection algorithm.

[0047] That is, the sending node defines the transmission mechanism of the reference signal and the data channel on the same time-frequency resources (i.e., the above-mentioned correlation relationship of the transmission power), and notifies the receiving node of this transmission mechanism. When the sending node sends the reference signal and the data channel on the same transmission resource according to this transmission mechanism, the receiving node can better cooperate with the detection algorithm after receiving this transmission mechanism, thereby improving the signal detection performance.

[0048] It should be noted that in the embodiments of the present disclosure, the data channel may be a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The reference signal may be a demodulation reference signal (DMRS) or a sounding reference signal (SRS) or other reference signals suitable for demodulating a data channel.

[0049] In addition, in the embodiment of the present disclosure, the first node 101 may be a receiving node, such as a passive IoT device, a tag, or a terminal, etc. The second node 102 may be a sending node, such as a base station, an auxiliary node, an intermediate node, etc.

[0050] Among them, the base station (BS) can be a base station or evolutionary node B (eNB or eNodeB) in LTE, long term evolution advanced (LTEA), a base station device (gNB) in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remotes, reconfigurable intelligent surfaces (RISs), routers, relay stations, transmission and reception points (TRP), receivers, access points, wireless fidelity (WIFI) devices and other network-side devices. The base station is sometimes also called a reader or reader used to communicate with the terminal.

[0051] The terminal can be a device with wireless transceiver function. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal can sometimes also be called a user, user equipment (UE), A-IoT device, access terminal, UE unit, UE station, mobile station, mobile station, remote station, transmitter, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent or UE device, etc., and the embodiments of the present disclosure do not limit this.

[0052] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of devices included in the Figure 1 In addition to the devices shown, the communication system may also include other devices, such as core network devices.

[0053] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0054] Figure 2 A flow chart of a communication method is shown, Figure 2 As shown, the communication method is applied to a first node, comprising:

[0055] S201. Receive power information sent by a second node.

[0056] The power information is used to indicate the correlation between the transmission power of the reference signal and the transmission power of the data channel.

[0057] As a possible implementation manner, the power information may include a power information value, and the power information value may satisfy any one of the following 1.1-1.4:

[0058] 1.1. The power information value is the transmission power of the reference signal, and the transmission power of the data channel is the difference between the power information value and the preset threshold;

[0059] 1.2. The power information value is the transmission power of the data channel, and the transmission power of the reference signal is the difference between the power information value and the preset threshold;

[0060] 1.3. The power information value is the ratio of the transmission power of the reference signal to the transmission power of the data channel;

[0061] 1.4. The power information value is the ratio of the transmission power of the data channel to the transmission power of the reference signal.

[0062] It should be noted that in the embodiments of the present disclosure, the transmission power of the reference signal and the transmission power of the data channel may be standardized values. For example, the value interval of the transmission power of the reference signal and the data channel is [0, 1], and the sum of the transmission power of the reference signal and the data channel is 1, then the preset threshold is 1.

[0063] For example, the standardized value interval is [0,1]:

[0064] When the power information value α is the power value of the reference signal r(m) on each RE, the power value of the data channel d(m) is 1-α, then the transmitted signal on each RE is

[0065] When the power information value α is the power value of the data channel d(m) on each RE, the power value of the reference signal r(m) is 1-α, then the transmission signal on each RE is

[0066] The power information value α is the power ratio between the reference signal r(m) and the data channel d(m) on each RE In the case of , the transmitted signal on each RE is

[0067] The power information value α is the power ratio between the data channel d(m) and the reference signal r(m) on each RE In the case of , the transmitted signal on each RE is

[0068] S202. Receive a reference signal and a data channel on the same target transmission resource according to the power information.

[0069] The reference signal and the data channel may be sent by the second node to the first node, or may be sent by a node other than the second node to the first node.

[0070] In the embodiments of the present disclosure, the target transmission resources may include: time domain resources (such as transmission symbols), frequency domain resources (such as subcarriers) and space domain resources (such as transmission layers).

[0071] That is, the reference signal and the data channel may be superimposed and transmitted on at least one of the subcarriers, transmission symbols, and transmission layers specified on the transmission bandwidth of the current data channel.

[0072] As a possible implementation manner, the power information value in the power information may include at least one of the following: a first information value in the frequency domain dimension, a second information value in the time domain dimension, and a third information value in the spatial domain dimension.

[0073] Wherein, when the power information value in the power information includes the first information value, the power values ​​of all subcarriers on the transmission bandwidth of the current data channel are the first information value;

[0074] In the case where the power information value in the power information includes the second information value, the power values ​​of all transmission symbols on the transmission bandwidth of the current data channel are the second information value;

[0075] In the case where the power information value in the power information includes the third information value, the power values ​​of all transmission layers on the transmission bandwidth of the current data channel are the third information values.

[0076] It should be noted that for the introduction of the power values ​​of the reference signal and the data channel on the transmission layer, please refer to the above description of the power values ​​of the reference signal and the data channel on the RE in the time-frequency dimension, which will not be repeated here.

[0077] It is understandable that the transceiver node can transmit the reference signal and the data channel simultaneously on the same transmission resource according to the predetermined correlation relationship between the transmission power of the reference signal and the data channel. In this way, by obtaining the correlation relationship between the transmission power of the reference signal and the data channel, the receiving node can better design the receiving algorithm and reduce the interference between the reference signal and the data channel, so as to realize the simultaneous transmission of the reference signal and the data channel on the same transmission resource, thereby reducing the reference signal overhead.

[0078] It should be noted that the transmission power of the reference signal and the transmission power of the data channel may be differentiated on different transmission resources.

[0079] For example, the transmission power of the reference signal and the transmission power of the data channel may be differentiated on subcarriers of different indexes.

[0080] For another example, the transmission power of the reference signal and the transmission power of the data channel may be distinguished on transmission symbols of different indexes.

[0081] For another example, the transmission power of the reference signal and the transmission power of the data channel may be differentiated on transmission layers of different indexes.

[0082] In some embodiments, the power information may include a reference power information value and at least one power information offset value.

[0083] The at least one power information bias value may include at least one of the following 2.1-2.3:

[0084] 2.1. At least one first power information offset value in the frequency domain dimension;

[0085] 2.2. at least one second power information offset value in the time domain dimension;

[0086] 2.3. At least one third power information offset value in the spatial dimension.

[0087] It should be noted that each first power information offset value may be an integer multiple of the first preset offset value. Alternatively, all first power information offset values ​​may be a first offset value set arranged in a random order (eg, {1, 5, 3, 6, 4, 7}).

[0088] Similarly, each second power information offset value may be an integer multiple of the second preset offset value. Alternatively, all second power information offset values ​​may be a second offset value set arranged in a random order.

[0089] Each third power information offset value may be an integer multiple of the third preset offset value. Alternatively, all third power information offset values ​​may be a third offset value set arranged in a random order.

[0090] In addition, the reference power information value may include at least one of the following: a first reference information value in the frequency domain dimension, a second reference information value in the time domain dimension, and a third reference information value in the spatial domain dimension.

[0091] As a possible implementation method, when the power information includes a first reference information value and at least one first power information bias value, there may be a group of subcarriers in the target transmission resource whose corresponding power value is equal to the first reference information value, and the power values ​​corresponding to other groups of subcarriers in the multiple groups of subcarriers are determined based on the first reference information value and at least one first power information bias value (such as determined by a combination of addition and subtraction operations).

[0092] The multiple groups of subcarriers may satisfy any of the following conditions:

[0093] The multiple groups of subcarriers are all subcarriers on the transmission bandwidth of the data channel;

[0094] The plurality of groups of subcarriers are part of subcarriers continuously distributed on the transmission bandwidth of the data channel;

[0095] The multiple groups of subcarriers are partial subcarriers discretely distributed on the transmission bandwidth of the data channel;

[0096] The plurality of groups of subcarriers are odd-indexed subcarriers on a transmission bandwidth of the data channel;

[0097] The multiple groups of subcarriers are even-indexed subcarriers on the transmission bandwidth of the data channel.

[0098] Exemplarily, the first power information offset value is used as the first preset offset value. As an example, an integer multiple of

[0099] If the multiple groups of subcarriers include a first group of subcarriers and a second group of subcarriers, the power value corresponding to the first group of subcarriers is equal to the first reference information value α 1 , the power value corresponding to the second group of subcarriers is equal to

[0100] If the multiple groups of subcarriers include a first group of subcarriers, a second group of subcarriers, and a third group of subcarriers, the power value corresponding to the first group of subcarriers is equal to the first reference information value α 1 , the power value corresponding to the second group of subcarriers is equal to The power value corresponding to the third group of subcarriers is equal to

[0101] If the multiple groups of subcarriers include a first group of subcarriers, a second group of subcarriers, a third group of subcarriers, and a fourth group of subcarriers, the power value corresponding to the first group of subcarriers is equal to the first reference information value α 1 , the power value corresponding to the second group of subcarriers is equal to The power value corresponding to the third group of subcarriers is equal to The power value corresponding to the fourth group of subcarriers is equal to

[0102] If the multiple groups of subcarriers include N+1 groups of subcarriers, then the power value corresponding to one group of subcarriers is equal to the first reference information value α 1 , the power values ​​corresponding to the other N groups of subcarriers are the same as the set The values ​​in correspond one to one.

[0103] Alternatively, all first power information offset values ​​are a first offset value set arranged in a random order. For example, if the multiple groups of subcarriers are N+1 groups of subcarriers, the power value corresponding to one group of subcarriers is equal to the first reference information value α 1 , the power values ​​corresponding to the other N groups of subcarriers are the same as the set There is a one-to-one correspondence between any N different values ​​in .

[0104] It should be noted that, in the case where the first reference information value in the reference power information value is the transmission power of the reference signal (that is, the first reference information value satisfies the above 1.1), or the power information value is the ratio of the transmission power of the reference signal to the transmission power of the data channel (that is, the first reference information value satisfies the above 1.3), as the subcarrier index number increases, the power values ​​corresponding to all subcarriers in the multiple groups of subcarriers of the target transmission resource tend to decrease first and then increase;

[0105] Similarly, when the first benchmark information value in the benchmark power information value is the transmission power of the data channel (i.e., the first benchmark information value satisfies the above 1.2), or the power information value is the ratio of the transmission power of the data channel to the transmission power of the reference signal (i.e., the first benchmark information value satisfies the above 1.4), as the subcarrier index number increases, the power values ​​corresponding to all subcarriers in multiple groups of subcarriers of the target transmission resource show a trend of first increasing and then decreasing.

[0106] Exemplarily, a group of subcarriers corresponding to the first reference information value in multiple groups of subcarriers is divided into two parts and is respectively located at the starting position and the ending position of the multiple groups of subcarriers, while each group of subcarriers in other groups of subcarriers is divided into two parts and is symmetrically distributed on both sides of the middle position of the multiple groups of subcarriers in order from large to small according to the corresponding first power information bias value.

[0107] The following takes multiple groups of subcarriers as all subcarriers on the transmission bandwidth of a data channel as an example, and introduces the change trend of the power values ​​corresponding to all subcarriers in combination with specific examples.

[0108] For example, the transmission bandwidth of the data channel may be N re , all subcarriers are N re subcarriers, and N re ={0,1,…,N re -1}.

[0109] like Figure 3 As shown, N re The subcarrier index value gradually increases with the arrow direction (from low frequency to high frequency), and N re The subcarriers are divided into 2 groups (each group corresponds to a power value), where the first group of subcarriers consists of 2K at both ends of the frequency domain. 1 subcarriers, the second group of subcarriers is the remaining middle (N re -2K 1) subcarriers, and the power values ​​corresponding to these two groups of subcarriers have two values:

[0110] For the first benchmark information value that satisfies 1.1 or 1.3 above, these two values ​​are and In this way, as the subcarrier index value increases, the power values ​​on all subcarriers in the transmission bandwidth show a trend of gradually decreasing and then gradually increasing, and show a symmetrical trend at the center of the transmission bandwidth.

[0111] For the first benchmark information value that satisfies 1.2 or 1.4 above, these two values ​​are and In this way, as the subcarrier index value increases, the power values ​​on all subcarriers in the transmission bandwidth show a trend of gradually increasing and then gradually decreasing, and show a symmetrical trend at the center of the transmission bandwidth.

[0112] It should be noted that K 1 is an integer and satisfies 1≤K 1 <(N re -2K 1 ).

[0113] like Figure 4 As shown, N re The subcarrier index value gradually increases with the arrow direction (from low frequency to high frequency), and N re The subcarriers are divided into 3 groups (each group corresponds to a power value), where the first group of subcarriers consists of 2K 1 subcarriers, the second group of subcarriers is 2K adjacent to the first group of subcarriers 2 subcarriers, and the third group of subcarriers is the remaining middle (N re -2K 1 -2K 2 ) subcarriers, and the power values ​​corresponding to these three groups of subcarriers have three values:

[0114] For the first benchmark information value that satisfies 1.1 or 1.3 above, these three values ​​are and In this way, as the subcarrier index value increases, the power values ​​on all subcarriers in the transmission bandwidth show a trend of gradually decreasing and then gradually increasing, and show a symmetrical trend at the center of the transmission bandwidth.

[0115] For the first benchmark information value that satisfies 1.2 or 1.4 above, these three values ​​are and In this way, as the subcarrier index value increases, the power values ​​on all subcarriers in the transmission bandwidth show a trend of gradually increasing and then gradually decreasing, and show a symmetrical trend around the center of the transmission bandwidth.

[0116] It should be noted that K 1 and K 2 is an integer and satisfies any of the following 3.1-3.3:

[0117] 3.1 K 1 =K 2 ,like

[0118] 3.2 K 1 >K 2 ,like

[0119] 3.3 K 1 <K 2 ,like

[0120] like Figure 5 As shown, N re The subcarrier index value gradually increases with the arrow direction (from low frequency to high frequency), and N re The subcarriers are divided into 4 groups (each group corresponds to a power value), where the first group of subcarriers consists of 2K at both ends of the frequency domain. 1 subcarriers, the second group of subcarriers is 2K adjacent to the first group of subcarriers 2 The third group of subcarriers is composed of 2K subcarriers adjacent to the second group of subcarriers. 3 subcarriers, the fourth group of subcarriers is the remaining middle (N re -2K 1 -2K 2 -2K 3 ) subcarriers, and the power values ​​corresponding to these four groups of subcarriers have four values:

[0121] For the first benchmark information value that satisfies 1.1 or 1.3 above, these four values ​​are and In this way, as the subcarrier index value increases, the power values ​​on all subcarriers in the transmission bandwidth show a trend of gradually decreasing and then gradually increasing, and show a symmetrical trend at the center of the transmission bandwidth.

[0122] For the first benchmark information value that satisfies 1.2 or 1.4 above, these four values ​​are and In this way, as the subcarrier index value increases, the power values ​​on all subcarriers in the transmission bandwidth show a trend of gradually increasing and then gradually decreasing, and show a symmetrical trend at the center of the transmission bandwidth.

[0123] It should be noted that K 1 , K 2 and K 3 is an integer and satisfies any of the following 4.1-4.4:

[0124] 4.1 K 1 =K 2 =K 32 ,like

[0125] 4.2 K 1 >K 2 >K 3 ,like

[0126] 4.3 K 1 <K 2 <K 3 ,like

[0127] 4.4 K 1 , K 2 and K 3 They are not equal to each other and have no descending or ascending order, such as

[0128] As a possible implementation method, when the power information includes a second reference information value and at least one second power information bias value, there may be a group of transmission symbols among the multiple groups of transmission symbols in the target transmission resource whose corresponding power value is equal to the second reference information value, and the power values ​​corresponding to other groups of transmission symbols in the multiple groups of transmission symbols are determined based on the second reference information value and at least one second power information bias value (such as determined by a combination of addition and subtraction operations).

[0129] Among them, the multiple groups of transmission symbols can satisfy any of the following:

[0130] The multiple groups of transmission symbols are all transmission symbols on the transmission bandwidth of the data channel;

[0131] The multiple groups of transmission symbols are part of the transmission symbols continuously distributed on the transmission bandwidth of the data channel;

[0132] The multiple groups of transmission symbols are partial transmission symbols discretely distributed on the transmission bandwidth of the data channel;

[0133] The multiple groups of transmission symbols are transmission symbols with odd indexes on the transmission bandwidth of the data channel;

[0134] The multiple groups of transmission symbols are transmission symbols with even indexes on the transmission bandwidth of the data channel.

[0135] Exemplarily, the second power information offset value is used as the second preset offset value. As an example, an integer multiple of

[0136] If the multiple groups of transmission symbols include a first group of transmission symbols and a second group of transmission symbols, the power value corresponding to the first group of transmission symbols is equal to the second reference information value α 2 , the power value corresponding to the second group of transmission symbols is equal to

[0137] If the multiple groups of transmission symbols include a first group of transmission symbols, a second group of transmission symbols, and a third group of transmission symbols, the power value corresponding to the first group of transmission symbols is equal to the second reference information value α 2 , the power value corresponding to the second group of transmission symbols is equal to The power value corresponding to the third group of transmission symbols is equal to

[0138] If the multiple groups of transmission symbols include a first group of transmission symbols, a second group of transmission symbols, a third group of transmission symbols, and a fourth group of transmission symbols, the power value corresponding to the first group of transmission symbols is equal to the second reference information value α 2 , the power value corresponding to the second group of transmission symbols is equal to The power value corresponding to the third group of transmission symbols is equal to The power value corresponding to the fourth group of transmission symbols is equal to

[0139] If the multiple groups of transmission symbols include N+1 groups of transmission symbols, then the power value corresponding to one group of transmission symbols is equal to the second reference information value α 2 , the power values ​​corresponding to the other N groups of transmission symbols are the same as the set The values ​​in correspond one to one.

[0140] Alternatively, all second power information offset values ​​are a second offset value set arranged in a random order. For example, if the multiple groups of transmission symbols are N+1 groups of transmission symbols, then the power value corresponding to one group of transmission symbols is equal to the second reference information value α 2 , the power values ​​corresponding to the other N groups of transmission symbols are the same as the set There is a one-to-one correspondence between any N different values ​​in .

[0141] It should be noted that, in the case where the second reference information value in the reference power information value is the transmission power of the reference signal (i.e., the second reference information value satisfies the above 1.1), or the power information value is the ratio of the transmission power of the reference signal to the transmission power of the data channel (i.e., the second reference information value satisfies the above 1.3), as the transmission symbol index number increases, the power values ​​corresponding to all transmission symbols in the multiple groups of transmission symbols of the target transmission resource tend to decrease first and then increase;

[0142] Similarly, when the second benchmark information value in the benchmark power information value is the transmission power of the data channel (i.e., the second benchmark information value satisfies the above 1.2), or the power information value is the ratio of the transmission power of the data channel to the transmission power of the reference signal (i.e., the second benchmark information value satisfies the above 1.4), as the transmission symbol index number increases, the power values ​​corresponding to all transmission symbols in multiple groups of transmission symbols of the target transmission resource show a trend of first increasing and then decreasing.

[0143] Exemplarily, a group of transmission symbols corresponding to the second reference information value in multiple groups of transmission symbols is divided into two parts and located at the starting position and the ending position of the multiple groups of transmission symbols respectively, while each group of transmission symbols in other groups of transmission symbols is divided into two parts and are symmetrically distributed on both sides of the middle position of the multiple groups of transmission symbols in order from large to small according to the corresponding second power information bias value.

[0144] The following takes multiple groups of transmission symbols as all transmission symbols on the transmission bandwidth of a data channel as an example, and introduces the change trend of the power values ​​corresponding to all transmission symbols in combination with specific examples.

[0145] For example, the transmission bandwidth of the data channel may be N sym , all transmitted symbols are N sym transmission symbols, and N sym ={0,1,…,N sym -1}.

[0146] like Figure 6 As shown, N sym The transmission symbol index value increases gradually along the arrow direction, and N sym The transmission symbols are divided into 2 groups (each group corresponds to a power value), where the first group of transmission symbols consists of 2S at both ends of the frequency domain. 1 transmission symbols, and the second group of transmission symbols is the remaining middle (N sym -2S 1 ) transmission symbols, and the power values ​​corresponding to these two groups of transmission symbols have two values:

[0147] For the second reference information value that satisfies 1.1 or 1.3 above, these two values ​​are and In this way, as the transmission symbol index value increases, the power values ​​on all transmission symbols in the transmission bandwidth show a trend of gradually increasing and then gradually decreasing, and show a symmetrical trend around the center position of the transmission symbol.

[0148] For the second reference information value that satisfies 1.2 or 1.4 above, these two values ​​are and In this way, as the transmission symbol index value increases, the power values ​​on all transmission symbols in the transmission bandwidth show a trend of gradually decreasing and then gradually increasing, and show a symmetrical trend around the center position of the transmission symbol.

[0149] It should be noted that S 1 is an integer and satisfies

[0150] like Figure 7 As shown, N sym The transmission symbol index value increases gradually along the arrow direction, and N sym The transmission symbols are divided into 3 groups (each group corresponds to a power value), where the first group of transmission symbols consists of 2S at both ends of the frequency domain. 1 transmission symbols, the second group of transmission symbols is 2S adjacent to the first group of transmission symbols 2 transmission symbols, and the third group of transmission symbols is the remaining middle (N sym -2S 1 -2S 2 ) transmission symbols, and the power values ​​corresponding to these three groups of transmission symbols have three values:

[0151] For the second reference information value that satisfies 1.1 or 1.3 above, these three values ​​are and In this way, as the transmission symbol index value increases, the power values ​​on all transmission symbols in the transmission bandwidth show a trend of gradually increasing and then gradually decreasing, and show a symmetrical trend around the center position of the transmission symbol.

[0152] For the second reference information value that satisfies 1.2 or 1.4 above, these three values ​​are and In this way, as the transmission symbol index value increases, the power values ​​on all transmission symbols in the transmission bandwidth show a trend of gradually decreasing and then gradually increasing, and show a symmetrical trend around the center position of the transmission symbol.

[0153] It should be noted that S 1 and S 2 is an integer and satisfies any of the following 5.1-5.3:

[0154] 5.1 S 1 =S 2 , such as N sym =14, then S 1 =S 2 =2;

[0155] 5.2 S 1 >S 2 , such as N sym =12, S 1 =2, S 2 =1;

[0156] 5.3 S 1 2 , such as N sym =12, S 1 =1, S 2 =3.

[0157] As a possible implementation method, when the power information includes a third reference information value and at least one third power information bias value, there may be a group of transmission layers in the target transmission resources (i.e., multiple groups of transmission layers on the transmission bandwidth of the data channel) whose corresponding power value is equal to the third reference information value, and the power values ​​corresponding to other groups of transmission layers in the multiple groups of transmission layers are determined based on the third reference information value and at least one third power information bias value (such as determined by a combination of addition and subtraction operations).

[0158] Exemplarily, the third power information offset value is the third preset offset value. As an example, an integer multiple of

[0159] If each group of transmission layers includes only one transmission layer, the power values ​​corresponding to all transmission layers in the multiple groups of transmission layers are equal to the set The values ​​in correspond to each other, and the power value corresponding to the first group of transmission layers in the multiple groups of transmission layers is equal to the third reference information value α 3 ,In this way, as the transmission layer index number increases, the power values ​​corresponding to all transmission layers in the multiple groups of transmission layers show a decreasing or increasing trend.

[0160] If each group of transmission layers includes at least two adjacent transmission layers, the power values ​​corresponding to all transmission layers in the multiple groups of transmission layers are equal to the set The values ​​in correspond to each other, and the power value corresponding to the first group of transmission layers in the multiple groups of transmission layers is equal to the third reference information value α 3 Thus, as the transmission layer index number increases, the power values ​​corresponding to all transmission layers in the multiple groups of transmission layers show a decreasing or increasing trend (ie, there is a gradually decreasing or increasing trend between groups).

[0161] Alternatively, all the third power information offset values ​​are a third offset value set arranged in a random order. ​For example, if the multiple transmission layers are N+1 transmission layers, then the power values ​​corresponding to all transmission layers in the multiple transmission layers are equal to the set There is a one-to-one correspondence between any N different values ​​in the transmission layer, and as the transmission layer index number increases, the power values ​​corresponding to all transmission layers in the multiple groups of transmission layers show a disordered trend (ie, there is no ascending or descending arrangement).

[0162] The following takes all transmission layers on the transmission bandwidth of a data channel as an example, and introduces the change trend of the power values ​​corresponding to all transmission layers in combination with specific examples.

[0163] For example, the transmission bandwidth of the data channel may be N L , all transport layers are N L transport layers, and N L ={0,1,…,N L -1}.

[0164] If the power values ​​corresponding to all transmission layers in multiple groups of transmission layers increase with the increase of transmission layer index numbers, then N L The power values ​​corresponding to the transmission layers are N L A value, the value is Or the value is in and

[0165] If the power values ​​corresponding to all transmission layers in multiple groups of transmission layers decrease as the transmission layer index increases, then N L The power values ​​corresponding to the transmission layers are N L A value, the value is Or the value is in and

[0166] If the power values ​​corresponding to all transmission layers in multiple groups of transmission layers show a disordered trend as the transmission layer index number increases, then N L The power values ​​corresponding to the transmission layers are N L A value, the value is in

[0167] If N L In the transmission layers, two transmission layers form a group, and each group is an adjacent transmission layer. The third basic information value corresponding to each group is the same, but the power value between the groups shows a gradually increasing trend, then N L The power value on the transmission layer is A value, the value is Or the value is in and

[0168] If N L In the transmission layers, two transmission layers form a group, and each group is an adjacent transmission layer. The third basic information value corresponding to each group is the same, but the power value between the groups shows a gradually decreasing trend. Then N L The power value on the transmission layer is A value, the value is Or the value is in and

[0169] In some embodiments, the power information may simultaneously include a first reference information value, a second reference information value, at least one first power information bias value and at least one second power information bias value. In this case, the power value of one group of time-frequency resources among multiple groups of time-frequency resources of the target transmission resources is the reference power information value, and the power values ​​of other groups of time-frequency resources are determined based on the reference power information value, at least one first power information bias value and at least one second power bias information value; the time-frequency resources include at least one subcarrier in the frequency domain and at least one transmission symbol in the time domain.

[0170] That is to say, the reference signal and the data channel can be superimposed and transmitted in the designated time-frequency resources, and the power value of the subcarriers in one group of time-frequency resources is the first reference information value, the power value of the transmission symbol in one group of time-frequency resources is the second reference information value, the power value of the subcarriers in other groups of time-frequency resources is determined based on the first reference information value and at least one first power information bias value, and the power value of the transmission symbol in other groups of time-frequency resources is determined based on the second reference information value and at least one second power information bias value.

[0171] It should be noted that, for the values ​​and changing trends of the power values ​​on the subcarriers and transmission symbols, reference may be made to the introduction of the above embodiments, which will not be described in detail here.

[0172] In some embodiments, the power information may simultaneously include a first reference information value, a third reference information value, at least one first power information offset value and at least one third power information offset value. At this time, the power value of one group of frequency-space resources among multiple groups of frequency-space resources of the target transmission resources is the reference power information value, and the power values ​​of other groups of frequency-space resources are determined based on the reference power information value, at least one first power information offset value and at least one third power offset information value; the frequency-space resources include at least one subcarrier in the frequency domain and at least one transmission layer in the spatial domain.

[0173] That is to say, the reference signal and the data channel can be superimposed and transmitted in the designated frequency and space resources, and the power value of the subcarriers in one group of frequency and space resources is the first reference information value, the power value of the transmission layer in one group of frequency and space resources is the third reference information value, the power value of the subcarriers in other groups of frequency and space resources is determined based on the first reference information value and at least one first power information bias value, and the power value of the transmission layer in other groups of frequency and space resources is determined based on the third reference information value and at least one third power information bias value.

[0174] It should be noted that for the values ​​and changing trends of the power values ​​on the subcarrier and the transmission layer, reference may be made to the introduction of the above embodiments, which will not be elaborated here.

[0175] In some embodiments, the power information may simultaneously include a second reference information value, a third reference information value, at least one second power information bias value and at least one third power information bias value. In this case, the power value of one group of space-time resources among multiple groups of space-time resources of the target transmission resources is the reference power information value, and the power values ​​of other groups of space-time resources are determined based on the reference power information value, at least one second power information bias value and at least one third power bias information value; the space-time resources include at least one transmission symbol in the time domain and at least one transmission layer in the spatial domain.

[0176] That is to say, the reference signal and the data channel can be superimposed and transmitted in the designated space-time resources, and the power value of the transmission symbol in one group of space-time resources is the second reference information value, the power value of the transmission layer in one group of space-time resources is the third reference information value, the power value of the transmission symbol in other groups of space-time resources is determined based on the second reference information value and at least one second power information bias value, and the power value of the transmission layer in other groups of space-time resources is determined based on the third reference information value and at least one third power information bias value.

[0177] It should be noted that for the values ​​and changing trends of the power values ​​on the transmission symbols and transmission layers, reference may be made to the introduction of the above embodiments, which will not be elaborated here.

[0178] In some embodiments, the power information may simultaneously include a first reference information value, a second reference information value, a third reference information value, at least one first power information bias value, at least one second power information bias value and at least one third power information bias value. At this time, the power value of one group of time-frequency-space resources among multiple groups of time-frequency-space resources of the target transmission resources is the reference power information value, and the power values ​​of other groups of time-frequency-space resources are determined based on the reference power information value, at least one first power information bias value, at least one second power information bias value and at least one third power bias information value; the time-frequency-space resources include at least one transmission symbol in the time domain, at least one subcarrier in the frequency domain, and at least one transmission layer in the spatial domain.

[0179] That is to say, the reference signal and the data channel can be superimposed and transmitted in the designated time-frequency-space resources, and the power value of the subcarriers in one group of time-frequency-space resources is the first reference information value, the power value of the transmission symbol in one group of time-frequency-space resources is the second reference information value, the power value of the transmission layer in one group of time-frequency-space resources is the third reference information value, the power value of the subcarriers in other groups of time-frequency-space resources is determined based on the first reference information value and at least one first power information bias value, the power value of the transmission symbol in other groups of time-frequency-space resources is determined based on the second reference information value and at least one second power information bias value, and the power value of the transmission layer in other groups of time-frequency-space resources is determined based on the third reference information value and at least one third power information bias value.

[0180] It should be noted that for the values ​​and changing trends of the power values ​​on the subcarrier, transmission symbol, and transmission layer, reference can be made to the introduction of the above embodiments, which will not be repeated here.

[0181] In some embodiments, the granularity of the power information indication varies, that is, the power information may be applicable to any of the following 6.1-6.3:

[0182] 6.1、Transmission bandwidth of data channel;

[0183] 6.2. A subband in the transmission bandwidth of a data channel;

[0184] 6.3. The bandwidth in which the data channel is transmitted.

[0185] A subband in the transmission bandwidth of the data channel is a part of the entire transmission bandwidth of the data channel, and the bandwidth where the data channel is transmitted is a bandwidth part (BWP).

[0186] It should be noted that the above embodiments are all introduced at the granularity of the transmission bandwidth of the data channel applicable to the power information. The following introduces two applicable situations 6.2 and 6.3 in combination with the embodiments.

[0187] As a possible implementation manner, taking a subband in the transmission bandwidth of a data channel in which power information is applicable as an example, power information of other subbands in the transmission bandwidth of the data channel is determined with reference to the power information of the indicated subband.

[0188] For example, the power information of other subbands in the transmission bandwidth of the data channel is the same as the power information of the indicated subband (that is, the power information of all subbands is the same). For another example, the power information of at least one of the other subbands in the transmission bandwidth of the data channel differs from the power information of the indicated subband by a preset information value (that is, the power information of at least two subbands in all subbands is different).

[0189] For example, taking the subcarriers in the transmission bandwidth of the data channel (ie, the target transmission resource is the subcarrier) as an example, if the transmission bandwidth of the current data channel includes N re subcarriers, where N re The subcarriers can be divided into N subband sub-bandwidths, each of which contains M re subcarriers, and N re Can be N re Divisible.

[0190] That is to say, compared with indicating power information at the granularity of the transmission bandwidth of the entire data channel, the subband changes from the total number of subcarriers in the transmission bandwidth to the total number of subcarriers in the subband in the frequency domain dimension.

[0191] Combined with the above Figure 4 ,like Figure 8 As shown, it shows the power value of the subcarrier of each subband in the transmission bandwidth of the data channel and the change trend of the power value. re Each subbandwidth of the subcarriers contains M re subcarriers.

[0192] It should be noted that the width of the subband may be equal to a channel state information (CSI) subband width configuration or a subband width configuration in a subband full-duplex system, or may be equal to one resource block (RB).

[0193] In this way, the current protocol configuration can be better compatible and the complexity of the receiving node detecting the signal using the nonlinear detection algorithm can be reduced.

[0194] It should be noted that, for the value and change trend of the power value on the time-frequency-space resources of the sub-band, reference can be made to the introduction of the above embodiment, which will not be elaborated here.

[0195] Similarly, taking the bandwidth (ie, BWP) where the power information is applicable to the data channel transmission as an example, the transmission bandwidth of the data channel can be located at any bandwidth position in the BWP.

[0196] Among them, compared with the indication of power information at the granularity of the transmission bandwidth of the entire data channel, the BWP where the data channel is transmitted is changed from the total number of subcarriers in the transmission bandwidth to the total number of subcarriers in the BWP in the frequency domain dimension, and from the number of transmission symbols in the transmission bandwidth to the maximum number of symbols of the BWP 14 in the time domain dimension, and from the number of transmission layers of the current data channel to the maximum number of transmission layers that the BWP can support in the transmission layer dimension (i.e., the spatial domain dimension).

[0197] In addition, when the data channel and the reference signal are transmitted simultaneously and superimposed, the power information on the current transmission bandwidth is obtained based on the time-frequency resource position and the number of transmission layers of the BWP occupied by the current transmission bandwidth and the power information on the BWP.

[0198] It should be noted that the transmission resources corresponding to the bandwidth position of the transmission bandwidth of the data channel in the BWP may be located within a group of transmission resources of the same power value. Alternatively, the transmission resources corresponding to the bandwidth position of the transmission bandwidth of the data channel in the BWP may span multiple groups of transmission resources of at least two different power values.

[0199] As a possible implementation method, taking the transmission resource as a subcarrier as an example, when the power information is applicable to the bandwidth where the data channel is transmitted, and the transmission bandwidth of the data channel is located in any group of subcarriers in the bandwidth (that is, the transmission resource corresponding to the bandwidth position of the transmission bandwidth of the data channel in the BWP can be located in a group of transmission resources with the same power value), the power values ​​of all subcarriers in the transmission bandwidth of the data channel are the same as the power value of any group of subcarriers.

[0200] For example, if the bandwidth of the data channel transmission includes N re subcarriers, the transmission bandwidth of the current data channel includes C rg subcarriers, and the starting subcarrier is Then, in the frequency domain dimension, calculate which power value area of ​​the BWP the transmission bandwidth of the data channel falls into, and then take the corresponding value and assign it to the subcarrier of the transmission bandwidth of the data channel.

[0201] Combined with the above Figure 4 ,like Fig. 9 As shown, all subcarriers on the BWP are divided into 3 groups, and the 3 groups of subcarriers correspond to 3 power values, such as If the transmission bandwidth of the data channel falls within the BWP The power value of all subcarriers in the transmission bandwidth of the data channel is

[0202] Alternatively, when the transmission bandwidth of the data channel is located in at least two groups of subcarriers with different power values ​​in the bandwidth where the data channel transmission is located (that is, the transmission resources corresponding to the bandwidth position of the transmission bandwidth of the data channel in the BWP can span multiple groups of transmission resources with at least two different power values), the power value of the subcarrier in the transmission bandwidth of the data channel can meet any of the following 7.1-7.5:

[0203] 7.1. The power value of each subcarrier in the transmission bandwidth of the data channel is the same as the power value of the subcarriers at the same position in at least two groups of subcarriers with different power values;

[0204] 7.2. The power value of the subcarrier in the transmission bandwidth of the data channel is the average of the power values ​​of all subcarriers in at least two groups of subcarriers with different power values;

[0205] 7.3. The power value of all subcarriers in the transmission bandwidth of the data channel is the maximum value of the power value of all subcarriers in at least two groups of subcarriers with different power values;

[0206] 7.4. The power value of all subcarriers in the transmission bandwidth of the data channel is the minimum value of the power value of all subcarriers in at least two groups of subcarriers with different power values;

[0207] 7.5. The power values ​​of all subcarriers in the transmission bandwidth of the data channel are the weighted average of the power values ​​of all subcarriers in at least two groups of subcarriers with different power values.

[0208] For example, in combination with the above Fig. 9 ,like Fig.10 As shown, the transmission bandwidth of the data channel is located on BWP Take the value range as an example:

[0209] If the power value of the subcarrier in the transmission bandwidth of the data channel meets the above 7.1, the transmission bandwidth of the data channel falls into The power value of the subcarrier in the value range is fall into The power value of the subcarrier in the value range is

[0210] If the power value of the subcarrier in the transmission bandwidth of the data channel meets the above 7.2 or 7.5, the power value of all subcarriers in the transmission bandwidth of the data channel is The mean or weighted average of (or weighted average according to the proportion of subcarriers falling in each area);

[0211] If the power value of the subcarrier in the transmission bandwidth of the data channel meets the above 7.3 or 7.4, the power value of all subcarriers in the transmission bandwidth of the data channel is The maximum or minimum value in .

[0212] As a possible implementation method, taking the transmission resource as a transmission symbol as an example, when the power information is applicable to the bandwidth where the data channel transmission is located, and the transmission bandwidth of the data channel is located in any group of transmission symbols in the bandwidth (that is, the transmission resource corresponding to the bandwidth position of the transmission bandwidth of the data channel in the BWP can be located in a group of transmission resources with the same power value), the power values ​​of all transmission symbols in the transmission bandwidth of the data channel are the same as the power value of any group of transmission symbols.

[0213] For example, if the bandwidth of the data channel transmission includes N sym(eg, 14) transmission symbols, the transmission bandwidth of the current data channel includes N' sym transmission symbols, and the starting transmission symbol is Then, in the time domain dimension, calculate which power value area of ​​the BWP the transmission bandwidth of the data channel falls into, and then take the corresponding value and assign it to the transmission symbol of the transmission bandwidth of the data channel.

[0214] Combined with the above Figure 6 ,like Fig.11 As shown, all transmission symbols on the BWP are divided into 2 groups, and the 2 groups of transmission symbols correspond to 2 power values, such as If the transmission bandwidth of the data channel falls within the BWP The value range of the data channel transmission bandwidth is

[0215] Alternatively, when the transmission bandwidth of the data channel is located in at least two groups of transmission symbols of different power values ​​in the bandwidth where the data channel transmission is located (that is, the transmission resources corresponding to the bandwidth position of the transmission bandwidth of the data channel in the BWP can span multiple groups of transmission resources of at least two different power values), the power value of the transmission symbol in the transmission bandwidth of the data channel can meet any of the following 8.1-8.5:

[0216] 8.1. The power value of each transmission symbol in the transmission bandwidth of the data channel is the same as the power value of the transmission symbols at the same position in at least two groups of transmission symbols with different power values;

[0217] 8.2. The power value of a transmission symbol in the transmission bandwidth of the data channel is the average of the power values ​​of all transmission symbols in at least two groups of transmission symbols with different power values;

[0218] 8.3. The power values ​​of all transmission symbols in the transmission bandwidth of the data channel are the maximum values ​​of the power values ​​of all transmission symbols in at least two groups of transmission symbols with different power values;

[0219] 8.4. The power values ​​of all transmission symbols in the transmission bandwidth of the data channel are the minimum values ​​of the power values ​​of all transmission symbols in at least two groups of transmission symbols with different power values;

[0220] 8.5. The power values ​​of all transmission symbols in the transmission bandwidth of the data channel are the weighted average values ​​of the power values ​​of all transmission symbols in at least two groups of transmission symbols with different power values.

[0221] For example, in combination with the above Fig.11 ,like Fig.12 As shown, the transmission bandwidth of the data channel is located on BWP Take the value range as an example:

[0222] If the power value of the transmitted symbol in the transmission bandwidth of the data channel satisfies the above 8.1, then the transmission bandwidth of the data channel falls within The power value of the transmission symbol in the value range is fall into The power value of the transmission symbol in the value range is

[0223] If the power value of the transmission symbol in the transmission bandwidth of the data channel satisfies the above 8.2 or 8.5, then the power value of all transmission symbols in the transmission bandwidth of the data channel is The mean or weighted average of (or weighted average according to the proportion of transmission symbols falling in each area);

[0224] If the power value of the transmission symbol in the transmission bandwidth of the data channel satisfies the above 8.3 or 8.4, then the power value of all transmission symbols in the transmission bandwidth of the data channel is The maximum or minimum value in .

[0225] In some embodiments, when the power information is applicable to the bandwidth where the data channel is transmitted and the number of transmission layers of the data channel is N, the power values ​​corresponding to the N transmission layers of the data channel are the power values ​​of the first N transmission layers of all transmission layers on the bandwidth where the data channel is transmitted.

[0226] For example, Fig.13 As shown, if the bandwidth of the data channel transmission includes N maxL If there are 8 (e.g. 8) transmission layers (i.e. the maximum number of transmission layers that can be supported by the downlink or uplink), and the transmission bandwidth of the current data channel includes N (e.g. 4) transmission layers, then the power value corresponding to the 4 transmission layers is Fig.13 The power values ​​corresponding to the first 4 transmission layers among the 8 transmission layers shown.

[0227] The present disclosure also provides a communication method, which is applied to a second node, such as Fig.14 As shown, the communication method may include:

[0228] S1401. Send power information to the first node.

[0229] The second node sends power information to the first node, so that the first node can receive the reference signal and the data channel on the same target transmission resource according to the power information.

[0230] In some embodiments, after sending the power information to the first node, the second node may send a reference signal and a data channel to the first node on the same target transmission resource according to the power information.

[0231] It should be noted that, for the introduction of power information, reference may be made to the introduction in the above embodiment, which will not be repeated here.

[0232] The following takes the interaction between the first node and the second node as an example to introduce the communication method provided in the above embodiment. Fig.15 As shown, including:

[0233] S1501. The second node sends power information to the first node.

[0234] S1502: The first node receives power information sent by the second node.

[0235] S1503. The second node sends a reference signal and a data channel on the same target transmission resource according to the power information.

[0236] S1504. The first node receives a reference signal and a data channel on the same target transmission resource according to the power information.

[0237] It is understandable that, in order to implement the above functions, the communication device includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments of the present disclosure, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software.
