Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a signaling transmission method, device, storage medium and program product. Background Art

[0002] As the demand for transmission rates in wireless communication systems continues to grow, the future is likely to witness the deployment of larger antenna arrays. These larger antenna arrays not only greatly expand the spatial degrees of freedom, but also enable wireless communication systems to reuse more layers of data for efficient transmission. However, the increase in the number of multiplexed layers also correspondingly exacerbates the reference signal overhead problem. For example, the overhead of the demodulation reference signal (DMRS) will occupy more transmission resources. To meet this challenge, an innovative strategy is to mix data and reference signals on the same layer on the same time-frequency resource block. This aims to effectively improve the performance of wireless communication systems without consuming additional time-frequency resources and spatial resources.

[0003] However, it is worth noting that multiplexing multiple layers of data and reference signals on the same time-frequency resources may cause mutual interference between data and reference signals, which may reduce the performance of the wireless communication system.

[0038] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of 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 making creative work are within the scope of protection of the present disclosure.

[0039] It should be understood that the specific implementations described herein are only used to explain the present disclosure, and are not used to limit the present disclosure.

[0040] In the subsequent description, suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present disclosure and have no specific meanings themselves. Therefore, "module", "component" or "unit" may be used interchangeably.

[0041] 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 merely a description of the association relationship of associated objects, indicating that three relationships may exist. 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 "plurality" means two or more. The words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not limit them to be different.

[0042] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open, inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0043] The terms "first" and "second" are used for descriptive purposes only and should not 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. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0044] In the embodiments of 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 embodiments of 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.

[0045] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0046] Multi-antenna technology, as a key means to improve the spectrum efficiency of wireless communications, is widely used in various wireless communication systems. Multi-antenna technology includes but is not limited to multiple-input-multiple-output (MIMO), joint transmission (JT), high-frequency beamforming, etc. In order to fully unleash the potential of multi-antenna technology and ensure that communication nodes can efficiently utilize these antenna resources, it is particularly important to obtain relatively accurate channel information. Through accurate channel estimation, communication nodes can more intelligently adjust transmission parameters and optimize signal transmission paths, thereby improving the overall transmission efficiency, coverage, and reliability of the system.

[0047] With the increasing demand for transmission rates in mobile communication systems, the future is likely to witness the deployment of larger antenna arrays. The deployment of larger antenna arrays not only greatly expands the spatial freedom, but also enables the system to reuse more layers of data for efficient transmission. However, the increase in the number of multiplexed layers also correspondingly exacerbates the overhead problem of reference signals (such as DMRS). To meet this challenge, an innovative strategy is to mix data and reference signals on the same layer of the same time-frequency resource block. This aims to effectively improve the performance of wireless communication systems without consuming additional time-frequency resources and spatial resources.

[0048] However, it is worth noting that multiplexing multiple layers of data and reference signals on the same time-frequency resources may cause mutual interference between data and reference signals, which may reduce the performance of the wireless communication system. How to reasonably design the relationship between data of different layers and transmission resources between different ports to minimize the mutual interference between data and reference signals has become an urgent problem to be solved.

[0049] In view of this, the present disclosure provides a signaling transmission method, by generating signaling, the signaling includes first information, the first information is used to indicate the relationship between a first transmission resource and a second transmission resource; wherein the first transmission resource is at least used to transmit data, the second transmission resource is at least used to transmit a reference signal and data, and the second transmission resource is a subset of the first transmission resource; and sending signaling. In this way, in the case where data and reference signals are mixedly transmitted on the same layer of the same time-frequency resource block, the relationship between the first transmission resource for transmitting data and the second transmission resource for transmitting the reference signal and data is indicated by the first information, and the relationship between different first transmission resources and the second transmission resource for transmitting the reference signal and data is determined according to different channel state information. The receiving end can process the signals on these transmission resources more accurately, thereby reducing mutual interference between data and reference signals and improving the reception quality of reference signals. Here, the signal on the transmission resource includes at least one layer of data and / or reference signals, which will not be described one by one below.

In some examples, for example, 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, for example, when two communication nodes are device-to-device communications, 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.

[0084] In some examples, the second transmission resource is a subset of the first transmission resource, including the concept of a full subset, that is, the first transmission resource and the second transmission resource are the same, which will not be described in detail below.

[0085] In some embodiments, the resource unit of the transmission resource is also called a resource unit. Each resource unit corresponds to a symbol of the transmission resource, or a subcarrier of the transmission resource, or a resource element (RE) of the transmission resource, which will not be described in detail below.

[0086] It is understandable that each RE of the first transmission resource can be used to transmit data on at least one layer. A portion of REs on the first transmission resource is used to transmit a mixed signal of a reference signal and data, and this portion of the transmission resource is called a second transmission resource. The transmission resources include but are not limited to at least one or more resources in the time domain resources, frequency domain resources, code domain resources, and space domain resources.

[0087] In the present disclosure, data on at least one layer can also be understood as data on at least one port, that is, data is transmitted on a transmission resource corresponding to a layer or a port. A reference signal on at least one layer can also be understood as a reference signal on at least one port, that is, a reference signal is transmitted on a transmission resource corresponding to a layer or a port, which will not be described in detail below.

[0088] In some examples, the data transmitted on the first transmission resource and the second transmission resource may include data on one or more transmission layers, which will not be described in detail below.

[0089] In some examples, the reference signal transmitted on the second transmission resource may include reference signals on one or more ports, which will not be described in detail below.

[0090] In some embodiments, the relationship between the first transmission resource and the second transmission resource includes at least one of the following:

[0091] a resource unit indication of the second transmission resource relative to the first transmission resource;

[0092] a ratio of the size of the second transmission resource to the size of the first transmission resource;

[0093] The resource unit indication of the second transmission resource relative to the first transmission resource includes one of the following:

[0094] A starting symbol index and / or number of symbols of the second transmission resource relative to the first transmission resource;

[0095] A starting symbol index and / or symbol interval of the second transmission resource relative to the first transmission resource;

[0096] The second transmission resource is indicated by a symbol index set or a symbol bitmap of the first transmission resource;

[0097] A starting subcarrier index and / or number of subcarriers of the second transmission resource relative to the first transmission resource;

[0098] a starting subcarrier index and / or subcarrier spacing of the second transmission resource relative to the first transmission resource;

[0099] The second transmission resource is indicated by a subcarrier index set or a subcarrier bitmap of the first transmission resource;

[0100] A starting resource element index and / or a number of resource elements of the second transmission resource relative to the first transmission resource;

[0101] a starting resource element index and / or resource element spacing of the second transmission resource relative to the first transmission resource;

[0102] The second transmission resource is indicated by a resource element index set or a resource element bitmap of the first transmission resource.

[0103] In some embodiments, the ratio of the size of the second transmission resource to the size of the first transmission resource includes at least one of the following:

[0104] a ratio of the number of symbols corresponding to the second transmission resource to the number of symbols corresponding to the first transmission resource;

[0105] a ratio of the number of subcarriers corresponding to the second transmission resource to the number of subcarriers corresponding to the first transmission resource;

[0106] a ratio of the number of resource elements corresponding to the second transmission resource to the number of resource elements corresponding to the first transmission resource;

[0107] The ratio of the size of the second transmission resource to the size of the first transmission resource is a non-negative number that is less than or equal to a first preset value.

[0108] In some examples, the relationship between the first transmission resource and the second transmission resource includes a ratio A of the size of the second transmission resource to the size of the first transmission resource, wherein the ratio A is a real number greater than or equal to 0 and less than or equal to 1. In one example, the ratio A includes but is not limited to one of the following: 1, 1 / 2, 1 / 3, 1 / 4, 1 / 5. In some examples, the ratio A is a positive real number a / b less than or equal to 1, a and b are positive integers, and a is less than or equal to b, a and b are the number of symbols of the second transmission resource and the number of symbols of the first transmission resource, respectively, or a and b are the number of subcarriers of the second transmission resource and the number of subcarriers of the first transmission resource, respectively, or a and b are the number of REs of the second transmission resource and the number of REs of the first transmission resource, respectively, or a and b are the number of PRBs of the second transmission resource and the number of PRBs of the first transmission resource, respectively.

[0109] For example, Figure 3 As shown, the first transmission resource includes multiple physical resource blocks (PRBs), each PRB includes 12 subcarriers and 14 symbols, and the ratio of the size of the second transmission resource to the size of the first transmission resource is 1 / 2. In other examples, the number of symbols of the PRB can also be other positive integers other than 14, and the subcarrier can also be a positive integer other than 12. The ratio of the size of the second transmission resource to the size of the first transmission resource can also be other real numbers between 0 and 1. It will not be repeated one by one below.

[0110] In some examples, the resource unit indication of the second transmission resource relative to the first transmission resource is the starting symbol index and / or the number of symbols of the second transmission resource relative to the first transmission resource. For example, in one example, the starting symbol index is L1, and the communication node determines the L1th to L1+L2-1th symbols of the first transmission resource occupied by the second transmission resource according to the starting symbol index L1 and the number of symbols L2. Here, the number of symbols can be default, or determined according to the relationship between the second transmission resource and the first transmission resource, such as determined according to the ratio of the number of symbols of the first transmission resource to the number of symbols of the second transmission resource and the number of symbols of the first transmission resource. In other examples, the symbols here can be replaced by subcarriers or REs. The symbol index can be replaced by a subcarrier index or an RE index, the number of symbols can be replaced by the number of subcarriers or the number of REs, and the symbol interval can be replaced by a subcarrier interval or an RE interval, which will not be described one by one below.

[0111] In some examples, the resource unit indication of the second transmission resource relative to the first transmission resource is the starting symbol index and / or symbol interval of the second transmission resource relative to the first transmission resource. For example, in one example, the starting symbol index is L1, and the communication node determines the L1+(i-1)*Kth symbol of the first transmission resource occupied by the second transmission resource based on the starting symbol index L1 and the symbol interval K, i=1, 2,..., C, C is the number of symbols corresponding to the second transmission resource, and L1+i*K is less than the total number of symbols of the first transmission resource. In one example, K=2, when L1=0, the second transmission resource corresponds to the transmission resource on the even symbols of the first transmission resource, and when L1=1, the second transmission resource corresponds to the transmission resource on the odd symbols of the first transmission resource. In other examples, the symbols here can be replaced by subcarriers or REs. The symbol index can be replaced by the subcarrier index or the RE index, which will not be described one by one later.

[0112] In some examples, the resource unit indication of the second transmission resource relative to the first transmission resource is a symbol index set of the second transmission resource in the first transmission resource. The symbol index set includes one or more symbol indices. Most of the one or more symbol indices can be based on the starting symbol index of the frame structure, for example, a time slot includes L symbols, and the symbol occupied by the second transmission resource is I. 1 , I 2 ,…I C , C is the number of symbols corresponding to the second transmission resource. 1 , I 2 ,…I C are different positive integers and are less than or equal to L. In one example, the symbol index here is the symbol index relative to the first transmission resource. For example, the symbol index starting point of the first transmission resource is I 0 , then the symbol index of the second transmission resource is I 0 +I i , i=i=1, 2, ..., C. In other examples, the symbol here can be replaced by a subcarrier or RE. The symbol index can be replaced by a subcarrier index or a RE index, which will not be described in detail below.

[0113] In some examples, the resource unit indication of the second transmission resource relative to the first transmission resource is a symbol bitmap indication of the second transmission resource in the first transmission resource, the symbol bitmap is an array of length L, when the i-th bit in the array takes the first value, it indicates that the i-th symbol belongs to the second transmission resource, and when the i-th bit in the array takes the second value, it indicates that the i-th symbol does not belong to the second transmission resource, i=1, ..., L. In other examples, the symbol here can be replaced by a subcarrier or RE. The symbol index can be replaced by a subcarrier index or an RE index, which will not be described one by one below.

[0114] In some embodiments, the relationship between the first transmission resource and the second transmission resource is determined based on channel state information, wherein the channel state information includes at least one of the following:

[0115] The number of ports for the reference signal;

[0116] Modulation method of the reference signal;

[0117] The modulation method of the data;

[0118] Channel rank.

[0119] In some examples, the relationship between the Xth transmission resource and the Yth transmission resource includes at least two relationships R1 and R2. Here, the relationships R1 and R2 can be ratios of different sizes of the first transmission resource and the second transmission resource, or resource unit indications of different second transmission resources relative to the first transmission resource. In some embodiments, the Xth transmission resource and the Yth transmission resource can be one of the following: the second transmission resource and the first transmission resource; the third transmission resource and the first transmission resource; the third transmission resource and the second transmission resource. They will not be described one by one below.

[0120] In one example, different reference signal port numbers correspond to different relationships between the second transmission resource and the first transmission resource, for example, when the port number is d1, the corresponding relationship is R1, and when the port number is d2, the corresponding relationship is R2. In other examples, the port number can be replaced by the channel rank, which will not be described one by one below.

[0121] In an example, different reference signal port number groups correspond to different relationships between the first transmission resource and the second transmission resource. For example, when the port number group is d1, the corresponding relationship is R1, and when the port number group is d2, the corresponding relationship is R2.

[0122] In an example, different modulation sizes correspond to different relationships between the first transmission resource and the second transmission resource. For example, when the modulation size is d1, the corresponding relationship is R1, and when the modulation size is d2, the corresponding relationship is R2.

[0123] In an example, different modulation mode groups correspond to different relationships between the first transmission resource and the second transmission resource. For example, when the modulation mode group is d1, the corresponding relationship is R1, and when the modulation mode group is d2, the corresponding relationship is R2.

[0124] These embodiments will not be described in detail below, and symmetrically, the relationship between the Xth transmission resource and the Yth transmission resource can be similarly replaced with the relationship between the Yth transmission resource and the Xth transmission resource, such as the first transmission resource and the second transmission resource; the first transmission resource and the third transmission resource; the second transmission resource and the third transmission resource. They will not be described one by one below.

[0125] In this way, by flexibly configuring the relationship between different transmission resources through different channel state information, when the modulation mode or channel rank is relatively small, the transmission resources of the reference signals of the two ports can be fully or partially multiplexed on the time-frequency resources, and when the modulation mode or channel rank is relatively large, the transmission resources of the reference signals of the two ports have no intersection on the time-frequency resources, thereby better reducing the interference between data and reference signals. This ensures that the transmission resources are efficiently utilized and improves the performance of the wireless communication system, which will not be described in detail later.

[0126] In some examples, the relationship between the second transmission resource and the first transmission resource is determined according to the number of ports of the reference signal. In one example, the number of reference signal ports is c, then the number of symbols occupied by the second transmission resource is K*c, where c and K are positive integers, and K*c is less than or equal to the number of symbols occupied by the first transmission resource d. Thus, the ratio A=K*c / d can be calculated. In one example, the number of reference signal ports is divided into e groups, each group of reference signal ports includes at least one reference signal port, and the i-th group of reference signal ports corresponds to the ratio value Ai. If the port corresponding to the reference signal belongs to the i-th group of reference signal ports, then the ratio of the second transmission resource to the first transmission resource is determined to be Ai. In other examples, the number of symbols can be replaced by the number of subcarriers or the number of resource elements, etc., which will not be repeated here. In other examples, the number of reference signal ports can also be changed to the channel rank, which will not be repeated here. In other examples, other relationships other than the ratio of the second transmission resource size to the first transmission resource size can be determined according to the number of reference signals, which will not be repeated here.

[0127] In some examples, the relationship between the second transmission resource and the first transmission resource is determined according to the modulation mode of the reference signal. For example, the modulation modes are divided into e groups, each modulation mode group includes at least one modulation mode, and the modulation mode of the i-th group corresponds to the ratio value Ai. If the modulation mode corresponding to the reference signal belongs to the i-th group of modulation modes, then the ratio of the second transmission resource to the first transmission resource is determined to be Ai. In other examples, the modulation mode here can be replaced by one of the following: modulation order, modulation coding scheme MCS, modulation scheme. They will not be described one by one later. For example, the modulation schemes QAM, 16QAM, and 64QAM are one group, and other modulation schemes greater than 64AQM are another group. When the modulation scheme corresponding to the reference signal belongs to QAM, 16QAM, and 64QAM, the ratio value is determined to be A1 (such as 1 / 3, 1 / 4, etc.), otherwise, the ratio is A2 (such as 1,

[0128] 1 / 2, etc.). For another example, the modulation order is less than 4 for one modulation mode group, and the ratio is determined to be A1, and the modulation order is greater than 4 for one modulation mode group, and the ratio is determined to be A2. Or the MCS is less than 8 for one modulation mode group, and the ratio is determined to be A1, and the MCS is greater than 8 for another modulation mode group, and the ratio is determined to be A2. In other examples, the modulation mode of the reference signal can also be replaced by the modulation mode of the data, such as the modulation mode of the data on the first transmission resource. In other examples, other relationships other than the ratio of the second transmission resource size to the first transmission resource size can be determined according to the modulation mode of the reference signal, which will not be repeated here.

[0129] In some embodiments, the signaling also includes second information, and the second information is used to indicate the relationship between at least one third transmission resource and the second transmission resource; wherein the third transmission resource is used to transmit the reference signal and data of at least one layer (which can be a transmission layer), and the third transmission resource is a subset of the second transmission resource, wherein the reference signal of at least one layer can be replaced by a reference signal on at least one port.

[0130] In some examples, the third transmission resource transmits reference signals on r1 ports, and the total number of reference signals to be transmitted is r2, then r1 is less than or equal to r2, and r1 and r2 are positive integers.

[0131] In some examples, the data transmitted on the third transmission resource includes data on one or more transmission layers, which will not be described in detail below.

[0132] In some embodiments, the relationship between the third transmission resource and the second transmission resource includes at least one of the following:

[0133] a resource unit indication of the third transmission resource relative to the second transmission resource;

[0134] a ratio of the size of the third transmission resource to the size of the second transmission resource;

[0135] The resource unit indication of the third transmission resource relative to the second transmission resource includes one of the following:

[0136] A starting symbol index and / or number of symbols of the third transmission resource relative to the second transmission resource;

[0143] a starting resource element index and / or resource element spacing of the third transmission resource relative to the second transmission resource;

[0144] The third transmission resource is indicated by a resource element index set or a resource element bitmap of the second transmission resource.

[0145] In some examples, the ratio of the size of the third transmission resource to the size of the second transmission resource includes at least one of the following:

[0146] A ratio of the number of symbols corresponding to the third transmission resource to the number of symbols corresponding to the second transmission resource;

[0147] A ratio of the number of subcarriers corresponding to the third transmission resource to the number of subcarriers corresponding to the second transmission resource;

[0148] The ratio of the number of resource elements corresponding to the third transmission resource to the number of resource elements corresponding to the second transmission resource.

[0149] In some embodiments, the ratio B of the size of the third transmission resource to the size of the second transmission resource is a real number greater than or equal to 0 and less than or equal to 1. In one example, the ratio B includes but is not limited to one of the following: 1, 1 / 2, 1 / 3, 1 / 4, 1 / 5. In some examples, B = a1 / b1, wherein a1 and b1 are the number of symbols of the third transmission resource and the number of symbols of the second transmission resource, respectively, or a1 and b1 are the number of subcarriers of the third transmission resource and the number of subcarriers of the second transmission resource, respectively, or a1 and b1 are the number of REs of the third transmission resource and the number of REs of the second transmission resource, respectively, or a1 and b1 are the number of PRBs of the third transmission resource and the number of PRBs of the second transmission resource, respectively.

[0150] In some examples, the resource unit indication of the third transmission resource relative to the second transmission resource is the starting symbol index and / or the number of symbols of the third transmission resource relative to the second transmission resource. For example, in one example, the starting symbol index is L1, and the communication node determines the Si+L1 to Si+L1+L2-1 symbols occupied by the third transmission resource according to the starting symbol index L1 and the number of symbols L2. Here, the number of symbols can be default, or determined according to the relationship between the third transmission resource and the second transmission resource, such as determined by the number of reference signals multiplied by the ratio of the number of symbols corresponding to the third transmission resource of each reference signal and the number of symbols corresponding to the second transmission resource, Si is the offset of the i-th third transmission resource, which is a non-negative integer. In other examples, the symbols here can be replaced by subcarriers or REs. The symbol index can be replaced by a subcarrier index or a RE index.

[0151] In some examples, the resource unit indication of the third transmission resource relative to the second transmission resource is the starting symbol index and / or symbol interval of the third transmission resource relative to the second transmission resource. For example, in one example, the starting symbol index is L1, and the communication node determines the Si+L1+(i-1)*Kth symbol of the second transmission resource occupied by the third transmission resource according to the starting symbol index L1 and the symbol interval K, i=1, 2, ..., C, C is the number of symbols corresponding to the third transmission resource, and Si+L1+i*K is less than the total number of symbols of the second transmission resource, Si is the offset of the i-th third transmission resource, which is a non-negative integer. In one example, K=2, when L1=0, the third transmission resource corresponds to the even symbols of the second transmission resource, and when L1=1, the third transmission resource corresponds to the odd symbols of the second transmission resource.

[0152] In some examples, the resource unit indication of the third transmission resource relative to the second transmission resource is a symbol index set of the third transmission resource in the second transmission resource, and the symbol index set includes one or more symbol indices. Most of the one or more symbol indices can be based on the symbol index of the time slot, for example, a time slot includes L symbols, and the symbol occupied by the third transmission resource is I. 1 , I 2 ,…I C , C is the number of symbols corresponding to the third transmission resource. 1 , I 2 ,…I C are mutually different positive integers and are less than or equal to L. In one example, the symbol index here is a symbol index relative to the second transmission resource. For example, the symbol index starting point of the second transmission resource is I 0 , then the symbol index of the third transmission resource is Si+I 0 +I i, i=i=1,2,…,C,Si is the offset of the i-th third transmission resource, which is a non-negative integer.

[0153] In some examples, the resource unit indication of the third transmission resource relative to the second transmission resource is a symbol bitmap indication of the third transmission resource in the second transmission resource, the symbol bitmap is an array of length L, when the i-th bit in the array takes the first value, it indicates that the i-th symbol in the second transmission resource belongs to the third transmission resource, and when the i-th bit in the array takes the second value, it indicates that the i-th symbol in the second transmission resource does not belong to the third transmission resource, i=1, ..., L. In other examples, the symbol index of the i-th third transmission resource also needs to be added with a time offset Si, Si is the offset of the i-th third transmission resource, and is a non-negative integer.

[0154] In some embodiments, a relationship between at least one third transmission resource and the second transmission resource is determined based on channel state information, wherein the channel state information includes at least one of the following:

[0155] the number of ports of the reference signal transmitted by the third transmission resource;

[0156] a modulation mode of a reference signal transmitted by a third transmission resource;

[0157] a modulation mode of data transmitted by the third transmission resource;

[0158] a modulation mode of data transmitted by the second transmission resource;

[0159] Channel rank.

[0160] In some examples, the relationship between the third transmission resource and the second transmission resource is determined according to the number of reference signal ports. For example, if the total number of reference signal ports is c, the number of symbols occupied by each third transmission resource is floor(b1 / c), where c and b1 are positive integers and floor is a floor function. b1 is one of the following for the second transmission resource: the number of symbols, the number of subcarriers, the number of REs, or the number of PRBs.

[0161] In some embodiments, the ratio of the size of the third transmission resource to the size of the second transmission resource is greater than or equal to 1 / P; P is the number of ports or channel rank of the reference signal.

[0162] In some embodiments, when the number of ports of the reference signal is a, the ratio of the size of the third transmission resource to the size of the second transmission resource is 1 / b, where b is 1 or a real number less than or equal to a.

[0163] For example, when the number of ports of the reference signal is 2, the ratio of the size of the third transmission resource to the size of the second transmission resource includes at least but is not limited to one of the following: 1, 1 / 2; when the number of ports of the reference signal is 4, the ratio of the size of the third transmission resource to the size of the second transmission resource includes at least but is not limited to one of the following: 1, 1 / 2, 1 / 4; when the number of ports of the reference signal is 8, the ratio of the size of the third transmission resource to the size of the second transmission resource includes at least but is not limited to one of the following: 1, 1 / 2, 1 / 4, 1 / 8. By analogy, the ratios under other numbers of ports will not be repeated here.

[0164] In some examples, the relationship between the third transmission resource and the second transmission resource is determined according to the modulation mode of the reference signal. For example, the modulation modes are divided into f groups, each modulation mode group includes at least one modulation mode, and the i-th group of modulation modes corresponds to the ratio value Bi. If the modulation mode corresponding to the reference signal belongs to the i-th group of modulation modes, then the ratio of the size of the third transmission resource to the size of the second transmission resource is determined to be Bi. In other examples, the modulation mode here can be replaced by one of the following: modulation order, modulation coding scheme MCS, modulation scheme. They will not be described one by one below. In other examples, the modulation mode of the reference signal can also be replaced by the modulation mode of the data, such as the modulation mode of the data on the first transmission resource.

[0165] In some embodiments, the signaling further includes third information, where the third information is used to indicate a power relationship between the reference signal and the data; wherein the power relationship between the reference signal and the data includes at least one of the following:

[0166] A ratio of a reference signal transmission power on an Xth transmission resource to a data transmission power on a Yth transmission resource;

[0170] Among them, the Xth transmission resource is the second transmission resource or the third transmission resource, the Yth transmission resource is one of the following: the first transmission resource, the second transmission resource, the third transmission resource, and the fourth transmission resource. The third transmission resource is used to transmit the reference signal and data of at least one layer, and the fourth transmission resource is the other transmission resource in the first transmission resource except the second transmission resource. The Xth transmission resource and the Yth transmission resource are different transmission resources, which will not be described one by one later.

[0171] In some examples, the reference signal transmission power on the Xth transmission resource refers to the sum of the transmission powers of the reference signals on all layers or specified layers on the Xth transmission resource, or refers to the sum of the transmission powers of the reference signals on all layers or specified layers on a resource unit on the Xth transmission resource. This will not be described in detail later.

[0172] In some examples, the data transmission power on the Yth transmission resource refers to the sum of the transmission powers of data on all layers or specified layers on the Xth transmission resource, or refers to the sum of the transmission powers of data on all layers or specified layers on a resource unit on the Xth transmission resource, which will not be repeated hereafter.

The Yth transmission resource here can be the first transmission resource, the second transmission resource, or the fourth transmission resource.

[0177] In some examples, the second transmission resource is used to transmit a reference signal and data, and the first transmission resource may have two parts, the first part is the second transmission resource part, and the second part is other transmission resources except the second transmission resource, such as the fourth transmission resource, and the fourth transmission resource is only used to transmit data.

[0178] In one example, the second transmission resource transmits a reference signal on at least one port and data on at least one layer. In a specific example, the reference signal on at least one port includes at least one of the following: the reference signal P 1 , ..., reference signal P K Among them, the reference signal P i is the reference signal on the i-th reference signal port, i=1, ..., K, K is a positive integer.

[0188] In some embodiments, the relationship between the third transmission resource and the first transmission resource includes at least one of the following:

[0189] a resource unit indication of the third transmission resource relative to the first transmission resource;

[0190] a ratio of a size of the third transmission resource to a size of the first transmission resource;

[0191] The resource unit indication of the third transmission resource relative to the first transmission resource includes one of the following:

[0192] A starting symbol index and / or number of symbols of the third transmission resource relative to the first transmission resource;

[0193] A starting symbol index and / or symbol interval of the third transmission resource relative to the first transmission resource;

[0194] The third transmission resource is indicated by a symbol index set or a symbol bitmap of the first transmission resource;

[0195] A starting subcarrier index and / or number of subcarriers of the third transmission resource relative to the first transmission resource;

[0196] a starting subcarrier index and / or subcarrier spacing of the third transmission resource relative to the first transmission resource;

[0197] The third transmission resource is indicated by a subcarrier index set or a subcarrier bitmap of the first transmission resource;

[0198] a starting resource element index and / or a number of resource elements of the third transmission resource relative to the first transmission resource.

[0199] The ratio of the size of the third transmission resource to the size of the first transmission resource includes at least one of the following:

[0200] a ratio of the number of symbols corresponding to the third transmission resource to the number of symbols corresponding to the first transmission resource;

[0201] a ratio of the number of subcarriers corresponding to the third transmission resource to the number of subcarriers corresponding to the first transmission resource;

[0202] The ratio of the number of resource elements corresponding to the third transmission resource to the number of resource elements corresponding to the first transmission resource.

[0203] In some examples, the resource unit indication of the third transmission resource relative to the first transmission resource is the starting symbol index and / or the number of symbols of the third transmission resource relative to the first transmission resource. For example, in one example, the starting symbol index is L1, and the communication node determines the Si+L1 to Si+L1+L2-1 symbols of the first transmission resource occupied by the third transmission resource according to the starting symbol index L1 and the number of symbols L2. Here, the number of symbols can be default, or determined according to the relationship between the third transmission resource and the first transmission resource, such as determined according to the number of reference signals multiplied by the ratio of the number of symbols corresponding to the third transmission resource and the number of symbols corresponding to the first transmission resource for each reference signal, Si is the offset of the i-th third transmission resource, which is a non-negative integer. In other examples, the symbols here can be replaced by subcarriers or REs. The symbol index can be replaced by a subcarrier index or a RE index.

[0204] In some examples, the resource unit indication of the third transmission resource relative to the first transmission resource is the starting symbol index and / or symbol interval of the third transmission resource relative to the first transmission resource. For example, in one example, the starting symbol index is L1, and the communication node determines the Si+L1+(i-1)*Kth symbol of the first transmission resource occupied by the third transmission resource according to the starting symbol index L1 and the symbol interval K, i=1, 2, ..., C, C is the number of symbols corresponding to the third transmission resource, and Si+L1+i*K is less than the total number of symbols of the first transmission resource, Si is the offset of the i-th third transmission resource, which is a non-negative integer. In one example, K=2, when L1=0, the third transmission resource corresponds to the even symbols of the first transmission resource, and when L1=1, the third transmission resource corresponds to the odd symbols of the first transmission resource.

[0205] In some examples, the resource unit indication of the third transmission resource relative to the first transmission resource is a symbol index set of the third transmission resource in the first transmission resource, and the symbol index set includes one or more symbol indices. Most of the one or more symbol indices can be based on the symbol index of the time slot, for example, a time slot includes L symbols, and the symbol occupied by the third transmission resource is I. 1 , I 2 ,…I C , C is the number of symbols corresponding to the third transmission resource. 1 , I 2 ,…I C are different positive integers and are less than or equal to L. In one example, the symbol index here is the symbol index relative to the first transmission resource. For example, the symbol index starting point of the first transmission resource is I 0 , then the symbol index of the third transmission resource is Si+I 0 +I i, i=i=1,2,…,C,Si is the offset of the i-th third transmission resource, which is a non-negative integer.

[0206] In some examples, the resource unit indication of the third transmission resource relative to the first transmission resource is a symbol bitmap indication of the third transmission resource in the first transmission resource, the symbol bitmap is an array of length L, when the i-th bit in the array takes the first value, it indicates that the i-th symbol in the first transmission resource belongs to the third transmission resource, when the i-th bit in the array takes the second value, it indicates that the i-th symbol in the first transmission resource does not belong to the third transmission resource, i=1, ..., L. In other examples, the symbol index of the i-th third transmission resource also needs to be added with a time offset Si, Si is the offset of the i-th third transmission resource, and is a non-negative integer.

[0207] In some embodiments, the signaling further includes fifth information, where the fifth information is used to indicate code domain information of a reference signal on the second transmission resource or the third transmission resource; wherein the code domain information includes at least one of the following:

[0208] an orthogonal cover (OCC) code indication for at least one reference signal port;

[0209] The length of the orthogonal cover code of at least one reference signal port, wherein the length of the orthogonal cover code is greater than or equal to a second preset value.

[0210] For example, the length of the orthogonal cover code of at least one reference signal port is greater than or equal to 2.

[0211] In some embodiments, the orthogonal cover code of the i-th layer reference signal is the same as the orthogonal cover code of the i-th layer data, i is a positive integer and is less than or equal to the number of ports or channel rank of the reference signal.

[0212] In some embodiments, the orthogonal cover code of the i-th layer reference signal is different from or orthogonal to the orthogonal cover code of the i-th layer data, and i is a positive integer and is less than or equal to the number of ports or channel rank of the reference signal.

[0213] In some other examples, the OCC code may be replaced by CDM, and the OCC length may be replaced by the CDM length.

[0214] In some embodiments, the at least one information included in the signaling corresponds to at least one of the following:

[0215] Physical layer signaling;

In one example, each information is a physical layer signaling. In one example, each information is a high-layer signaling. In one example, one or more information corresponds to different fields of the same physical layer signaling. In one example, one or more information corresponds to different fields of the same high-layer signaling. Among them, the content contained in the first information, the second information, the third information, the fourth information, and the fifth information can be specifically referred to the introduction in the above embodiment, and will not be repeated here.

[0220] In some examples, the first node uses a multi-antenna system and multiplexes multiple layers, that is, multiple data and / or reference signals can be transmitted simultaneously. In this case, since advanced signal processing methods can be used for channel estimation, such as nonlinear signal processing methods represented by artificial intelligence, one or more reference signals and / or data on one or more layers can be transmitted simultaneously multiplexed on all or part of the REs of the second transmission resource.

[0221] Taking the i-th layer and the j-th layer as an example, a combination of any two layers of reference signals and / or data is given below, where i and j are different positive integers. It should be noted that the transmission combination can be extended to any number of layers, such as three layers or four layers.

[0222] In a specific example, the reference signal Pi on the i-th reference signal port is transmitted on all or part of the REs of the first transmission resource.

[0223] In a specific example, the reference signal Pj on the j-th reference signal port is transmitted on all or part of the REs of the first transmission resource.

[0224] In a specific example, data Di on the i-th layer is transmitted on all or part of REs of the first transmission resource.

[0225] In a specific example, data Dj on the j-th layer is transmitted on all or part of the REs of the first transmission resource.

[0226] In a specific example, the reference signal Pi on the i-th reference signal port and the data Dj on the j-th layer are transmitted simultaneously in multiplexed manner on all or part of the REs of the first transmission resource.

[0227] In a specific example, a reference signal Pi on the i-th reference signal port and a reference signal Pj on the j-th reference signal port are transmitted simultaneously in multiplexed manner on all or part of the REs of the first transmission resource.

[0228] In a specific example, a reference signal Pi on the i-th reference signal port, a reference signal Pj on the j-th reference signal port, and data Dj on the j-th layer are simultaneously multiplexed and transmitted on all or part of the REs of the first transmission resource.

[0229] In a specific example, data Di on the i-th layer and data Dj on the j-th layer are transmitted simultaneously in multiplexed manner on all or part of the REs of the first transmission resource.

[0230] In a specific example, data Di on the i-th layer and a reference signal Pj on the j-th reference signal port are transmitted simultaneously in multiplexed manner on all or part of the REs of the first transmission resource.

[0231] In a specific example, data Di on the i-th layer, a reference signal Pj on the j-th reference signal port, and data Dj on the j-th layer are transmitted simultaneously and multiplexed on all or part of the REs of the first transmission resource.

[0235] S102: Send signaling to the second node.

[0236] In some embodiments, the first node sends a signaling to the second node, and correspondingly, the second node receives the signaling sent by the first node.

[0237] In some embodiments, the first node periodically sends signaling to the second node.

[0238] In some embodiments, the signaling is used for transmission resource configuration information, and the first node sends the transmission resource configuration information to the second node; correspondingly, the second node receives the transmission resource configuration information sent by the first node. The transmission resource configuration information is used to indicate one or more of the first transmission resource, the second transmission resource, and the third transmission resource.

[0239] In some examples, the first node divides the transmission resources into three parts: a first transmission resource, a second transmission resource, and a third transmission resource. In some examples, the first node divides the transmission resources into two parts: a first transmission resource and a second transmission resource. In one example, the second transmission resource is a subset of the first transmission resource. In some examples, the second transmission resource is the same as the first transmission resource. In this case, the reference signal and data transmitted on all transmission resources on at least one layer are mixed signals. In one example, a third transmission resource is a subset of the second transmission resource. In one example, a third transmission resource is the same as the second transmission resource. In this case, the reference signal and data on each layer occupy all the second transmission resources. Here, the transmission resource is at least one of the time domain resources, frequency domain resources, and code domain resources used to transmit reference signals and / or data. For example, the time-frequency resource used to transmit reference signals and / or data includes a set of one or more REs. Here, an RE is a time-frequency resource corresponding to a symbol and a subcarrier.

[0240] Based on this, in the case where data and reference signals are mixedly transmitted on the same layer of the same time-frequency resource block, the relationship between the first transmission resource for transmitting data and the second transmission resource for transmitting the reference signal and data is indicated by the first information, and based on different channel state information, the relationship between different first transmission resources and second transmission resources for transmitting the reference signal and data is determined. The receiving end can process the signals on these transmission resources more accurately, thereby reducing mutual interference between data and reference signals and improving the reception quality of reference signals.
