DETAILED DESCRIPTION

To enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings 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 of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

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 meaning "openly comprising", 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 the particular 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 representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

The terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature qualified by the terms "first," "second," and the like may explicitly or implicitly include one or more of such features. Throughout this disclosure, unless otherwise specified, "plurality" means two or more.

In the embodiments of the present disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

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.

Multi-antenna technology can improve the performance of wireless communication systems and 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), and high-frequency beamforming.

As mobile communication systems place increasingly higher demands on transmission rates, arrays with larger numbers of antennas may appear in the future, such as 64 antennas, 128 antennas, or even 256 antennas. More antennas will bring greater spatial freedom, allowing more layers of data to be multiplexed and transmitted simultaneously. As the number of multiplexing layers increases, the overhead of the reference signal also increases. For example, taking the demodulation reference signal (DMRS) as an example, the current DMRS and data transmission resources (transmission resources include at least one or more resources in the time domain, frequency domain, code domain, and spatial domain) are orthogonal, that is, they do not overlap, resulting in a large overhead for transmitting DMRS. How to reduce the overhead of reference signal The transmission resource overhead of the signal is an urgent problem to be solved.

Based on this, the embodiments of the present disclosure provide a method for sending and receiving transmission resource configuration information, a communication device and a storage medium. The first node determines the transmission resource configuration information, and the transmission resource configuration information is used to indicate a first transmission resource. The first transmission resource is used to transmit the reference signal of at least one port and the data of at least one layer. That is, the reference signal of at least one port and the data of at least one layer can be multiplexed and transmitted on the first transmission resource, reducing the transmission resource overhead of the reference signal.

The following describes the solutions of the embodiments of the present disclosure in conjunction with the accompanying drawings.

It should be understood that the specific implementations described herein are only used to illustrate the present disclosure, and are not intended to limit the present disclosure.

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

The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, new radio (NR) mobile communication networks using 5G, future mobile communication networks, such as the sixth-generation mobile communication technology (6G), or multiple communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

It should be understood that FIG1 is an exemplary structural diagram, and the number of devices included in the communication system shown in FIG1 is not limited. For example, the number of first nodes and second nodes is not limited. Furthermore, in addition to the devices shown in FIG1 , the communication system shown in FIG1 may also include other devices, which is not limited.

Next, as shown in FIG2 , an embodiment of the present disclosure provides a method for sending transmission resource configuration information. The method is applied to a first node, which may be the first node 110 shown in FIG1 . The method includes the following S101 - S102 .

S101: Determine transmission resource configuration information.

In some embodiments, in order to reduce the transmission resource overhead of the reference signal, the first node generates transmission resource configuration information, that is, determines the transmission resource configuration information.

In some examples, in order to generate transmission resource configuration information, 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, in order to generate transmission resource configuration information, the first node divides the transmission resources into two parts: a first transmission resource and a second transmission resource. The transmission resource is at least one of a time domain resource, a frequency domain resource, a code domain resource, and a spatial domain resource for transmitting a reference signal and/or data. For example, a time-frequency resource for transmitting a reference signal and/or data may include a set of one or more resource elements (REs). An RE is a time-frequency resource corresponding to one symbol and one subcarrier.

In some examples, the first node divides the transmission resources into two parts: a first transmission resource and a second transmission resource. In this case, the first transmission resource is used to transmit at least one reference signal and at least one data, and the second transmission resource is used to transmit at least one reference signal or at least one data. In some examples, the first node divides the transmission resources into two parts: a first transmission resource and a second transmission resource. In this case, the at least one reference signal of the third transmission resource can be replaced with at least one reference signal of the second transmission resource, and the reference signal of the third transmission resource can be replaced with the reference signal of the second transmission resource.

In one example, the first transmission resource is used to transmit N reference signals and M data, where N and M are positive integers. In one example, N + M > 2. In one example, N + M = 2, and the reference signals and data are transmitted on different layers, i.e., via different spatial resources.

In some embodiments, the described data may also be replaced by one of a data channel, a data stream, a layer of data, a data layer, etc.

In some embodiments, the transmission resource configuration information is used to indicate a first transmission resource, where the first transmission resource is used to transmit at least one reference signal and at least one data. As an example, a reference signal is one of the following K reference signals on ports: reference signal P ₁ , ..., reference signal _PK ; a data is one of the following K layers of data: data D ₁ , ..., data D _K , where K is an integer greater than 1. Reference signal P _i is the reference signal of the i-th port, and data D _i is the data on the i-th layer, where i = 1, ..., K. In some examples, a reference signal on a port corresponds to a reference signal resource, which typically includes multiple sets of time-frequency resource elements. The reference signal is transmitted on the reference signal resource. In some examples, data on a layer is data on a layer transmitted on a set of time-frequency resource elements.

For the description of the reference signal, reference may be made to the description of the reference signal in the above example, which will not be repeated here.

In some embodiments, the transmission resource configuration information is further used to indicate a second transmission resource, wherein the second transmission resource is used to transmit at least one data.

In some embodiments, the transmission resource configuration information is further used to indicate a second transmission resource, where the second transmission resource is used to transmit at least one data or a reference signal.

In some embodiments, the transmission resource configuration information is further used to indicate a third transmission resource, where the third transmission resource is used to transmit at least one reference signal.

In some embodiments, the first node uses a multi-antenna system and multiplexes multiple layers, that is, multiple data or reference signals can be transmitted simultaneously. In this case, because 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 multiplexed and transmitted simultaneously on all or part of the REs of the first transmission resource.

Taking the i-th layer and the j-th layer on the first transmission resource as an example, a combination of any two layers of reference signals and/or data is given, 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 and four layers.

In some embodiments, the reference signal P _i on the i-th port is transmitted on all or part of the REs of the first transmission resource.

In some embodiments, the reference signal P _j on the j-th port is transmitted on all or part of the REs of the first transmission resource.

In some embodiments, data D _i on the i-th layer is transmitted on all or part of the REs of the first transmission resource.

In some embodiments, data D _j on the j-th layer is transmitted on all or part of the REs of the first transmission resource.

In some embodiments, the reference signal P _i on the i-th port and the data D _j on the j-th layer are transmitted simultaneously in multiplexed form on all or part of the REs of the first transmission resource.

In some embodiments, the reference signal P _i on the i-th port and the reference signal P _j on the j-th port are transmitted simultaneously in multiplexed form on all or part of the REs of the first transmission resource.

In some embodiments, the reference signal P _i on the i-th port, the reference signal P _j on the j-th port, and the data D _j on the j-th layer are transmitted simultaneously in multiplexed form on all or part of the REs of the first transmission resource.

In some embodiments, data D _i on the i-th layer and data D _j on the j-th layer are transmitted simultaneously in a multiplexed manner on all or part of the REs of the first transmission resource.

In some embodiments, data D _i on the i-th layer and a reference signal P _j on the j-th port are transmitted simultaneously in a multiplexed manner on all or part of the REs of the first transmission resource.

In some embodiments, data D _i on the i-th layer, a reference signal P _j on the j-th port, and data D _j on the j-th layer are transmitted simultaneously in multiplexed form on all or part of the REs of the first transmission resource.

In some embodiments, the reference signal P _i on the i-th port and the data D _i on the i-th layer and the data D _j on the j-th layer are transmitted simultaneously in multiplexed form on all or part of the REs of the first transmission resource.

In some embodiments, the reference signal P _i on the i-th port, the data D _i on the i-th layer, and the reference signal P _j on the j-th port are transmitted simultaneously in multiplexed form on all or part of the REs of the first transmission resource.

In some embodiments, the reference signal P _i on the i-th port and the data D i on the i-th layer, the reference signal P _j on the j-th port and the data D _j on the j-th layer are simultaneously _multiplexed and transmitted on all or part of the REs of the first transmission resource.

In some embodiments, the configuration parameters of a reference signal for one port transmitted on a transmission resource may be different from the configuration parameters of a reference signal for another port transmitted on the same transmission resource. The configuration parameters include at least one of the following: reference signal sequence length, transmit power, modulation scheme, number of time-domain symbols, number of frequency-domain subcarriers, number of resource elements, sequence generation method, and sequence type.

As an example, the reference signal sequence length corresponding to the reference signal P _i transmitted on the Xth transmission resource is greater than or equal to the reference signal sequence length corresponding to the reference signal P _j transmitted on the Xth transmission resource, where i and j are positive integers less than or equal to K, and i is not equal to j. The Xth transmission resource can be the first transmission resource or the third transmission resource.

As an example, the transmit power of the reference signal P _i transmitted on the Xth transmission resource is greater than or equal to the transmit power of the reference signal P _j transmitted on the Xth transmission resource, where i and j are positive integers less than or equal to K, and i is not equal to j. The Xth transmission resource can be the first transmission resource or the third transmission resource.

As an example, the modulation mode of the reference signal P _i transmitted on the Xth transmission resource is greater than or equal to the modulation mode of the reference signal P _j transmitted on the Xth transmission resource; wherein i and j are positive integers less than or equal to K, and i is not equal to j, and the Xth transmission resource can be the first transmission resource or the third transmission resource.

As an example, the number of time-domain symbols used to transmit reference signal P _i on the Xth transmission resource is greater than or equal to the number of time-domain symbols used to transmit reference signal P _j on the Xth transmission resource, where i and j are positive integers less than or equal to K, and i is not equal to j. The Xth transmission resource may be the first transmission resource or the third transmission resource. That is, the number of time-domain symbols occupied by reference signal resources of different ports on the Xth transmission resource may be different.

As an example, the number of frequency-domain subcarriers for transmitting reference signal P _i on the Xth transmission resource is greater than or equal to the number of frequency-domain subcarriers for transmitting reference signal P _j on the Xth transmission resource, where i and j are positive integers less than or equal to K, and i is not equal to j. The Xth transmission resource may be the first transmission resource or the third transmission resource. That is, the number of frequency-domain subcarriers occupied by reference signal resources of different ports on the Xth transmission resource may be different.

As an example, the number of resource elements used to transmit reference signal P _i on the Xth transmission resource is greater than or equal to the number of resource elements used to transmit reference signal P _j on the Xth transmission resource, where i and j are positive integers less than or equal to K, and i is not equal to j. The Xth transmission resource may be the first transmission resource or the third transmission resource.
