[0001] The present disclosure claims priority to Chinese Patent Application No. 202410992514.3, filed on July 22, 2024, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

To address this challenge, an innovative strategy is to mix data and reference signals on the same layer on the same time-frequency resource block, which aims to effectively improve the performance of wireless communication systems without additional consumption of time-frequency resources and spatial resources.

[0036] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.

[0037] It should be understood that the embodiments described herein are merely used to explain the present disclosure, and are not used to limit the present disclosure.

[0038] In the subsequent description, the suffixes of "module", "part", or "unit" used to represent elements are merely used to facilitate the description of the present disclosure, and have no particular meaning by themselves, and thus, "module", "part", or "unit" can be mixedly used.

[0039] In the description of the present disclosure, unless otherwise stated, " / " means "or", for example, A / B can mean A or B. "And / or" herein is merely a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean: only A, A and B, and only B. In addition, "at least one" means one or more, and "multiple" means two or more. "First", "second", and the like do not limit the quantity and execution order, and "first", "second", and the like do not necessarily mean different.

[0040] Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an open, inclusive sense as "including, but not limited to." As used throughout the description and the claims, the term "one embodiment," "some embodiments," "an exemplary embodiment," "example," "specific example," or "some examples" means that a particular feature, structure, material, or characteristic is included in at least one embodiment or example of the disclosure, but not necessarily all embodiments or examples. The appearance of the phrases "in one embodiment" or "in some embodiments" in various places in the specification are not necessarily all referring to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0041] The terms "first", "second", etc. are used only to describe the purpose and are not to be construed as indicating or implying relative importance or a specific number of the technical features indicated. Thus, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the disclosure, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0042] In the embodiments of the disclosure, the expressions such as "exemplarily" or "for example" are used to represent as an example, illustration or description. Any embodiment or design scheme described as "exemplarily" or "for example" in the embodiments of the disclosure should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the expressions such as "exemplarily" or "for example" are intended to present the relevant concept in a detailed manner.

[0043] In addition, the use of "based on" means open and inclusive, because the process, step, calculation or other action "based on" one or more stated conditions or values can be based on additional conditions or beyond the stated values in practice.

[0044] Multi-antenna technology, as a key means to improve the spectrum efficiency of wireless communication, 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 release the potential of multi-antenna technology and ensure that the communication node can efficiently utilize these antenna resources, it is particularly important to obtain relatively accurate channel information. Through accurate channel estimation, the communication node can more intelligently adjust the transmission parameters, optimize the signal transmission path, and thus improve the overall transmission efficiency, coverage and reliability of the system.

[0045] With the increasing demand for transmission rate of mobile communication systems, it is highly likely that larger-scale antenna arrays will be deployed in the future. The deployment of larger-scale antenna arrays not only greatly expands the spatial degrees of freedom, but also enables the system to multiplex more layers of data for efficient transmission. However, the increase in the number of multiplexed layers also exacerbates the overhead problem of reference signals (such as DMRS). To address this challenge, an innovative strategy is to mix the data and reference signals on the same layer of the same time-frequency resource block, which aims to effectively improve the performance of the wireless communication system without additional consumption of time-frequency resources and spatial resources.

[0046] However, it is worth noting that multiplexing multiple layers of data and reference signals on the same time-frequency resource 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 the transmission resources of different layers of data and different ports to minimize the mutual interference between data and reference signals has become a problem to be solved.

[0047] In view of this, the present disclosure provides a signaling transmission method, which generates signaling, the signaling including first information, the first information being used to indicate the relationship between a first transmission resource and a second transmission resource; the first transmission resource being used at least for transmitting data, the second transmission resource being used at least for transmitting reference signals and data, the second transmission resource being a subset of the first transmission resource; and sending the signaling. In this way, in the case of mixed transmission of data and reference signals 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 reference signals and data is indicated by the first information, and different relationships between the first transmission resource and the second transmission resource are determined according to different channel state information, so that the receiving end can more accurately process the signals on these transmission resources, thereby reducing the mutual interference between data and reference signals and improving the reception quality of the reference signals. Here, the signals on the transmission resources include data and / or reference signals of at least one layer, which will not be described again in the embodiments of the present disclosure.

[0048] The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, a new radio (NR) mobile communication network using 5G, a future mobile communication network, for example, a 6th-generation mobile communication technology (6G), or a multi-communication convergence system, etc., and the embodiments of the present disclosure are not limited thereto.

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, in device-to-device communication, 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.

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.

[0108] In some examples, the resource unit of the second transmission resource relative to the first transmission resource is indicated as a starting symbol index and / or a number of symbols of the second transmission resource relative to the first transmission resource. For example, in one example, a starting symbol index L1, the communication node determines the second transmission resource occupying the L1th to L1+L2-1th symbols of the first 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 of the second transmission resource and the first transmission resource, such as determined according to the number of symbols of the first transmission resource and the ratio of the number of symbols of the second transmission resource to the number of symbols of the first transmission resource. In other examples, the symbol here can be replaced by subcarrier or RE.

[0109] In some examples, the resource unit indication of the second transmission resource relative to the first transmission resource is a starting symbol index and / or a symbol interval of the second transmission resource relative to the first transmission resource. For example, in one example, the starting symbol index L1, the communication node determines the second transmission resource occupying the L1+(i-1)*Kth symbol of the first transmission resource according to the starting symbol index L1 and the symbol interval K, i=1, 2, …, C, C being the number of symbols corresponding to the second transmission resource, and L1+i*K being 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 symbol herein can be replaced by subcarrier or RE. The symbol index can be replaced by subcarrier index or RE index, and the embodiments of the present disclosure will not be repeated.

[0110] 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 relative to the first transmission resource. The symbol index set includes one or more symbol indexes. The one or more symbol indexes can be based on the starting symbol index of the frame structure, for example, one time slot includes L symbols, and the second transmission resource occupies I1, I2, …, I C , C being the number of symbols corresponding to the second transmission resource. I1, I2, …, I C are mutually different positive integers and less than or equal to L. In one example, the symbol index herein is a symbol index relative to the first transmission resource. For example, the starting symbol index of the first transmission resource is I0, then the symbol index of the second transmission resource is I0+I i , i=1, 2, …, C. In other examples, the symbol herein can be replaced by subcarrier or RE. The symbol index can be replaced by subcarrier index or RE index, and the embodiments of the present disclosure will not be repeated.

[0111] 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 relative to the first transmission resource, and the symbol bitmap is an array with a length of L, the ith bit in the array taking a first value when the ith symbol belongs to the second transmission resource, and the ith bit in the array taking a second value when the ith symbol does not belong to the second transmission resource, i=1, …, L. In other examples, the symbol herein can be replaced by subcarrier or RE. The symbol index can be replaced by subcarrier index or RE index, and the embodiments of the present disclosure will not be repeated.

[0112] In some embodiments, the relationship between the first transmission resource and the second transmission resource is determined based on channel state information, and the channel state information includes at least one of the following:

[0113] a number of ports of the reference signal;

[0114] a modulation of the reference signal;

[0115] a modulation of the data;

[0116] a channel rank.

[0117] In some examples, the relationship of 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 a ratio of different first transmission resource sizes and second transmission resource sizes, or different resource unit indications of the second transmission resource relative to the first transmission resource. In some embodiments, the Xth transmission resource and the Yth transmission resource can be one of the following respectively: 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, which will not be repeated here.

[0118] In one example, different reference signal port numbers correspond to different relationships of the second transmission resource and the first transmission resource, such as, when the port number is d1, the relationship R1 is corresponded, and when the port number is d2, the relationship R2 is corresponded. In other examples, the port number can be replaced by a channel rank, which will not be repeated here.

[0119] In one example, different reference signal port number groups correspond to different relationships of the first transmission resource and the second transmission resource, such as, when the port number group is d1, the relationship R1 is corresponded, and when the port number group is d2, the relationship R2 is corresponded.

[0120] In one example, different modulation sizes correspond to different relationships of the first transmission resource and the second transmission resource, such as, when the modulation size is d1, the relationship R1 is corresponded, and when the modulation size is d2, the relationship R2 is corresponded.

[0121] In one example, different modulation groups correspond to different relationships of the first transmission resource and the second transmission resource, such as, when the modulation group is d1, the relationship R1 is corresponded, and when the modulation group is d2, the relationship R2 is corresponded.

[0122] For these examples, embodiments of the present disclosure will not be repeated in detail, and, symmetrically, the relationship of the Xth transmission resource and the Yth transmission resource can be replaced by the relationship of 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, which will not be repeated here.

[0123] Thus, the relationship between the different transmission resources is flexibly configured by different channel state information. When the modulation mode or the channel rank is small, the transmission resources of the reference signals of the two ports can be fully or partially multiplexed in time-frequency resources. When the modulation mode or the channel rank is large, the transmission resources of the reference signals of the two ports have no intersection in time-frequency resources. Thus, the interference between the data and the reference signals can be better reduced, the transmission resources can be efficiently utilized, and the performance of the wireless communication system is improved. Details are not described herein again.

[0124] 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 ports of the reference signal is c, the number of symbols occupied by the second transmission resource is K*c, c and K are positive integers, and K*c is less than or equal to the number of symbols d occupied by the first transmission resource. Thus, the ratio A = K*c / d can be calculated. In one example, the number of ports of the reference signal is divided into e groups, the number of ports of each group of the e groups of reference signal ports includes at least one reference signal port, and the i-th group of reference signal ports corresponds to a ratio value Ai. If the port corresponding to the reference signal belongs to the i-th group of reference signal ports, the ratio of the second transmission resource to the first transmission resource is determined as Ai. In other examples, the number of symbols can be replaced by the number of subcarriers or the number of resource elements, and details are not described herein again. In other examples, the number of ports of the reference signal can be replaced by the channel rank, and details are not described herein again. In other examples, the relationship between the size of the second transmission resource and the size of the first transmission resource can be determined according to the number of reference signals, and details are not described herein again.

[0125] In some examples, the relationship between the second and first transmission resources is determined based on the modulation scheme of the reference signal. For instance, modulation schemes are divided into e groups, each group including at least one modulation scheme, with the i-th group corresponding to a ratio value Ai. If the modulation scheme corresponding to the reference signal belongs to the i-th group, then the ratio of the second to the first transmission resource is determined to be Ai. In other examples, the modulation scheme can be replaced by one of the following: modulation order, modulation coding scheme (MCS), or modulation scheme, which will not be elaborated further in this disclosure. For example, modulation schemes QAM, 16QAM, and 64QAM form one group, and other modulation schemes greater than 64AQM form another group. If the modulation scheme corresponding to the reference signal belongs to QAM, 16QAM, or 64QAM, the ratio value is determined to be A1 (e.g., 1 / 3, 1 / 4, etc.); otherwise, the ratio value is A2 (e.g., 1, 1 / 2, etc.). For another example, modulation orders less than 4 form one modulation scheme group with a ratio value of A1, and modulation orders greater than 4 form another modulation scheme group with a ratio value of A2. Alternatively, a modulation scheme group with an MCS less than 8 can be identified, with a ratio value of A1; and a modulation scheme group with an MCS greater than 8 can be identified, with a ratio value of A2. In other examples, the modulation scheme of the reference signal can be replaced with the modulation scheme of the data, such as the modulation scheme of the data on the first transmission resource. In other examples, relationships other than the ratio of the second transmission resource size to the first transmission resource size can be determined based on the modulation scheme of the reference signal; these will not be elaborated further in this embodiment.

[0126] In some embodiments, the signaling further includes second information, which is used to indicate the relationship between at least one third transmission resource and the second transmission resource; the third transmission resource is used to transmit reference signals and data of at least one layer (which may be a transport layer), the third transmission resource is a subset of the second transmission resources, and the reference signals of at least one layer can be replaced by reference signals on at least one port.

[0127] 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. This disclosure will not elaborate further on this aspect.

[0128] In some examples, the data transmitted on the third transport resource includes data from one or more transport layers, which will not be described further in this disclosure.

[0145] a ratio of a number of resource elements corresponding to the third transmission resource and a number of resource elements corresponding to the second transmission resource.

[0146] In some embodiments, a ratio B of a size of the third transmission resource to a 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 = al / bl, al and bl are a number of symbols of the third transmission resource and a number of symbols of the second transmission resource respectively, or al and bl are a number of subcarriers of the third transmission resource and a number of subcarriers of the second transmission resource respectively, or al and bl are a number of REs of the third transmission resource and a number of REs of the second transmission resource respectively, or al and bl are a number of PRBs of the third transmission resource and a number of PRBs of the second transmission resource respectively.

[0147] In some examples, the resource unit of the third transmission resource relative to the second transmission resource is indicated as a starting symbol index and / or a number of symbols of the third transmission resource relative to the second transmission resource. For example, in one example, a starting symbol index L1, the communication node determines the third transmission resource occupying the Si+L1 to Si+L1+L2-1 symbols of the second transmission resource according to the starting symbol index L1 and a number of symbols L2. Here, the number of symbols can be default, or the number of symbols is determined according to the relationship between the third transmission resource and the second transmission resource, such as the number of symbols is 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 second transmission resource of each reference signal, Si is the offset of the i-th third transmission resource, and is a non-negative integer. In other examples, the symbol here can be replaced by subcarrier or RE. The symbol index can be replaced by subcarrier index or RE index.

[0148] In some examples, the resource unit of the third transmission resource relative to the second transmission resource is indicated as a starting symbol index and / or a symbol interval of the third transmission resource relative to the second transmission resource. For example, in one example, a starting symbol index L1, the communication node determines the third transmission resource occupying the Si+L1+(i-1)*K symbols of the second transmission resource according to the starting symbol index L1 and a 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, and is a non-negative integer. In one example, K = 2, when L1 = 0, the third transmission resource corresponds to even symbols of the second transmission resource, and when L1 = 1, the third transmission resource corresponds to odd symbols of the second transmission resource.

[0149] In some examples, the resource element of the third transport resource relative to the second transport resource is indicated as the symbol index set of the third transport resource in the second transport resource, the symbol index set including one or more symbol indices. One or more symbol indices can be determined based on the symbol indices of a time slot; for example, a time slot includes L symbols, and the symbols occupied by the third transport resource are I1, I2, ... I... C C represents the number of symbols corresponding to the third transmission resource. I1, I2, ... I C These are distinct positive integers, less than or equal to L. In one instance, the symbol index here is the symbol index relative to the second transport resource. For example, if the starting point of the symbol index of the second transport resource is I0, then the symbol index of the third transport resource is Si + I0 + I. i , i = 1, 2, ..., C, Si is the bias of the i-th third transmission resource and is a non-negative integer.

[0150] In some examples, the resource unit indication of the third transport resource relative to the second transport resource is the symbol bitmap indication of the third transport resource in the second transport resource. The symbol bitmap is an array of length L, where the first value of the i-th bit in the array indicates that the i-th symbol in the second transport resource belongs to the third transport resource, and the second value of the i-th bit in the array indicates that the i-th symbol in the second transport resource does not belong to the third transport resource, i = 1, ..., L. In other examples, the symbol index of the i-th third transport resource also needs to be added with a time offset Si, where Si is the offset of the i-th third transport resource and is a non-negative integer.

[0151] In some embodiments, the relationship between at least one third transmission resource and a second transmission resource is determined based on channel state information, wherein the channel state information includes at least one of the following:

[0155] The modulation scheme of the data transmitted by the second transmission resource;

[0156] Channel rank.

[0157] In some examples, the relationship between the third transmission resource and the second transmission resource is determined according to a quantity of ports of the reference signal. For example, if the total quantity of ports of the reference signal is c, then the third transmission resource occupies a quantity of symbols of floor(b1 / c), where c and b1 are positive integers, and floor is a floor function. b1 is one of the following of the second transmission resource: a quantity of symbols, a quantity of subcarriers, a quantity of REs, or a quantity of PRBs.

[0158] In some embodiments, a ratio of a size of the third transmission resource to a size of the second transmission resource is greater than or equal to 1 / P; P is a quantity of ports of the reference signal or a channel rank.

[0159] In some embodiments, in a case where the quantity 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.

For example, the modulation modes are divided into f groups, each of the f groups of modulation modes includes at least one modulation mode, and the i th group of modulation modes corresponds to a ratio value Bi. If the modulation mode of 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 of the reference signal can also be replaced by a modulation mode of data, such as a modulation mode of data on the first transmission resource.

[0200] In some examples, the resource unit of the third transmission resource relative to the first transmission resource is indicated by a starting symbol index and / or a number of symbols of the third transmission resource relative to the first transmission resource. For example, in one example, a starting symbol index L1, the communication node determines the third transmission resource occupying the S1+L1 to S1+L1+L2-1 symbols of the first transmission resource according to the starting symbol index L1 and the number of symbols L2. Here, the number of symbols can be default, or the number of symbols is determined according to the relationship between the third transmission resource and the first transmission resource, such as the number of symbols is 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 of each reference signal, S1 is the offset of the i-th third transmission resource, and is a non-negative integer. In other examples, the symbol here can be replaced by subcarrier or RE. The symbol index can be replaced by subcarrier index or RE index.

[0201] In some examples, the resource unit of the third transmission resource relative to the first transmission resource is indicated by a starting symbol index and / or a symbol interval of the third transmission resource relative to the first transmission resource. For example, in one example, a starting symbol index L1, the communication node determines the third transmission resource occupying the S1+L1+(i-1)*K symbols of the first 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 S1+L1+i*K is less than the total number of symbols of the first transmission resource, S1 is the offset of the i-th third transmission resource, and 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.

[0202] In some examples, the resource unit of the third transmission resource relative to the first transmission resource is indicated by a symbol index set of the third transmission resource in the first transmission resource, and the symbol index set includes one or more symbol indexes.

I1, I2, …, I Care different positive integers, and are less than or equal to L. In an example, the symbol index here is a symbol index relative to the first transmission resource. For example, if the symbol index of the first transmission resource starts at I0, then the symbol index of the third transmission resource is Si+I0+I i , i = 1, 2, …, C, Si is a bias of the ith third transmission resource, and is a non-negative integer.

[0203] In some examples, the resource unit indication of the third transmission resource relative to the first transmission resource is indicated by a symbol bitmap of the third transmission resource in the first transmission resource, the symbol bitmap being an array of length L, and the ith bit in the array taking a first value indicating that the ith symbol in the first transmission resource belongs to the third transmission resource, and the ith bit in the array taking a second value indicating that the ith 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 ith third transmission resource also needs to be added with a time bias Si, Si being a bias of the ith third transmission resource, and being a non-negative integer.

[0204] In some embodiments, the signaling further includes fifth information, the fifth information being used to indicate code domain information of the reference signal on the second transmission resource or the third transmission resource; the code domain information including at least one of:

[0205] an orthogonal cover code (OCC) indication of at least one reference signal port;

[0206] a length of the orthogonal cover code of the at least one reference signal port, the length of the orthogonal cover code being greater than or equal to a second preset value.

[0207] For example, the length of the orthogonal cover code of the at least one reference signal port is greater than or equal to 2.

[0208] In some embodiments, the orthogonal cover code of the ith layer of reference signal and the orthogonal cover code of the ith layer of data are the same, i being a positive integer and being less than or equal to the number of ports of the reference signal or the channel rank.

[0209] In some embodiments, the orthogonal cover code of the ith layer of reference signal and the orthogonal cover code of the ith layer of data are different or orthogonal, i being a positive integer and i being less than or equal to the number of ports of the reference signal or the channel rank.

[0210] In other examples, the OCC code can be replaced by CDM, and the OCC length can be replaced by CDM length.

[0217] In some examples, the first node uses a multi-antenna system, and multiple layers are multiplexed, that is, multiple data and / or reference signal transmissions can be multiplexed at the same time. In this case, since advanced signal processing methods can be used for channel estimation, such as nonlinear signal processing methods represented by artificial intelligence. Therefore, one or more reference signals and / or data on one or more layers can be simultaneously multiplexed and transmitted on all or part of the REs of the second transmission resource.

[0218] The following takes the i-th layer and the j-th layer as an example to give the combination of reference signals and / or data of any two layers, i and j are different positive integers, and it should be noted that the transmission combination can be extended to three layers, four layers, and any number of layers.

[0219] In one 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.

[0220] In one 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.

[0223] In one example, the reference signal Pi on the i-th reference signal port and the data Dj on the j-th layer are simultaneously multiplexed and transmitted on all or part of the REs of the first transmission resource.

[0224] In one example, the reference signal Pi on the i-th reference signal port, the reference signal Pj on the j-th reference signal port are simultaneously multiplexed and transmitted on all or part of REs of the first transmission resource.

[0226] In one example, the data Di on the i-th layer and the data Dj on the j-th layer are simultaneously multiplexed and transmitted on all or part of REs of the first transmission resource.

[0227] In one example, the data Di on the i-th layer, the reference signal Pj on the j-th reference signal port are simultaneously multiplexed and transmitted on all or part of REs of the first transmission resource.

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

[0233] In some embodiments, the first node sends signaling to the second node, and accordingly, the second node receives the signaling sent by the first node.

[0234] In some embodiments, the first node periodically sends signaling to the second node.

[0235] In some embodiments, the signaling is used to transmit resource configuration information, and the first node sends the resource configuration information to the second node; accordingly, the second node receives the resource configuration information sent by the first node. The resource configuration information is used to indicate one or more of the first transmission resource, the second transmission resource, and the third transmission resource.

[0236] In some examples, the first node divides the transmission resource into three parts: the first transmission resource, the second transmission resource, and the third transmission resource. In some examples, the first node divides the transmission resource into two parts: the first transmission resource and the 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, and the mixed signal of the reference signal and the data transmitted on all transmission resources of at least one layer. In one example, the third transmission resource is a subset of the second transmission resource. In one example, the third transmission resource is the same as the second transmission resource, and the reference signal and the data on each layer occupy all the second transmission resource. Here, the transmission resource is at least one of the time domain resource, the frequency domain resource, and the code domain resource used for transmitting the reference signal and / or the data. For example, the time-frequency resource used for transmitting the reference signal and / or the data includes a set of one or more REs. Here, an RE is a time-frequency resource corresponding to one symbol and one subcarrier.

[0237] Based on this, in the case of mixed transmission of data and reference signal on the same layer of the same time-frequency resource block, the first information is used to indicate the relationship between the first transmission resource for transmitting data and the second transmission resource for transmitting the reference signal and data, and different relationships between the first transmission resource for transmitting data and the second transmission resource for transmitting the reference signal and data are determined according to different channel state information, so that the receiving end can more accurately process the signals on these transmission resources, thereby reducing the mutual interference between the data and the reference signal and improving the reception quality of the reference signal.
