However, in current communication systems, the configuration of the demodulation reference signal corresponding to different antenna ports may be consistent, which reduces flexibility and affects the spectral efficiency of the communication system.

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0037] In the description of this application, 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 can 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 "a plurality" means two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not limit them to be necessarily different.
[0038] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.
[0039] In mobile communication systems, an antenna port is a logical transmission channel defined by a reference signal. For the receiver, an antenna port is an independent antenna channel. The transmitter sends a demodulation reference signal on the antenna port, and the receiver uses the demodulation reference signal to demodulate downlink or uplink data during transmission on the control channel or data channel. However, in general, the demodulation reference signal configuration used by different antenna ports is basically the same, such as the same number of time domain symbols, the same number of frequency domain subcarriers, and the channel processing method based on the demodulation reference signal measurement is transparent to the transmitter. This results in poor flexibility, high overhead, and the inability to adapt flexibly to the actual wireless channel environment, thus affecting the system's spectrum efficiency.
[0040] Based on this, the present disclosure provides a reference signal configuration method, comprising: generating reference signal configuration information, the reference signal configuration information including description information for each of M ports or each of M port groups, where M is a positive integer; and transmitting the reference signal configuration information. This allows each port or port group to have its own reference information configuration, enabling adaptive adjustment based on the actual wireless channel environment to meet transmission requirements in different service scenarios.
[0041] The method provided by the embodiment of the present disclosure can be applied to various communication systems. For example, the communication system can be a long term evolution (LTE) system, a fifth generation (5G) communication system, a Wi-Fi system, a communication system related to the third generation partnership project (3GPP), a future evolutionary communication system (such as a sixth generation (6G) communication system, etc.), or a system integrating multiple systems, etc., without limitation. The following describes the method provided by the embodiment of the present disclosure by taking the communication system 100 shown in Figure 1 as an example. Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided by the present disclosure.
[0042] FIG1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. As shown in FIG1 , the communication system 100 may include one or more network devices 11 and one or more terminal devices 12. The terminal device 12 may be communicatively connected to the one or more network devices 11.
[0043] In some embodiments, the network device 11 can be used to implement functions such as resource scheduling, wireless resource management, and wireless access control of terminal devices. For example, it can be an evolution nodeB (eNB), a next-generation base station (gNB), a transmission receive point (TRP), a transmission point (TP), and some other access nodes. Depending on the size of the service coverage area provided, the base station can be divided into a macro base station for providing macro cells (Macro cells), a micro base station for providing micro cells (Pico cells), and a femto base station for providing femto cells (Femto cells). With the continuous evolution of wireless communication technology, future base stations may also adopt other names.
[0044] The terminal device 12 may also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, etc. For example, the terminal device 12 may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality terminal, an augmented reality terminal, a wireless terminal used in industrial control, a wireless terminal used in unmanned driving, a wireless terminal used in remote surgery, a wireless terminal used in transportation safety, a wireless terminal used in smart cities, a wireless terminal used in smart homes, etc. The embodiments of the present disclosure do not limit the specific device form used by the terminal.
[0045] In some embodiments, during a communication process, a network device sends data to a terminal device, and the terminal device receives the data sent by the network device. Thus, the network device can be referred to as a transmitter. Accordingly, the terminal device can be referred to as a receiver. Alternatively, when a terminal device sends data to a network device, the network device can be referred to as a receiver. Accordingly, the terminal device can be referred to as a transmitter.
[0046] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices or nodes included in Figure 1 and the names of each device are not restricted. In addition to the functional nodes shown in Figure 1, the communication system may also include other nodes or devices, such as core network devices.
[0047] The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. A person skilled in the art will appreciate that, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.
[0048] The embodiments provided by the present disclosure are described in detail below with reference to the accompanying drawings.
[0049] As shown in FIG2 , an embodiment of the present disclosure provides a method for configuring a reference signal, which is applied to a transmitting device and includes the following steps:
[0050] S101: Generate reference signal configuration information, where the reference signal configuration information includes description information of each of M ports or description information of each of M port groups.
[0051] Wherein, M is a positive integer. Exemplarily, during a communication process, a transmitting device, such as the network device 11 shown in FIG1 , may generate reference signal configuration information and send the reference signal configuration information to a receiving device, such as the terminal device 12 shown in FIG1 .
[0052] In addition, the reference signals provided in the present disclosure include multiple types of reference signals, such as a channel state information reference signal (CSI-RS), a demodulation reference signal (Demodulation reference signal), a phase tracking reference signal (PTRS), a paging reference signal (SRS), etc.
[0053] In some embodiments, the reference signal configuration information further includes port number information N, where N is a positive integer greater than or equal to M.
[0054] In one example, the transmitting end device may determine the M ports from the N ports, which are antenna ports.
[0055] For example, the value of N is 32, and the value of M is 8. As shown in FIG3 , the transmitting end device may select 8 ports from the 32 ports, and then generate description information corresponding to each of the 8 ports, that is, generate the reference signal configuration information.
[0056] In addition, the other 24 ports among the 32 ports that are not selected, i.e., for which no description information is sent, may have corresponding default values. The reference signal configuration information may also include the default values corresponding to the 24 ports, or other signaling may be used to carry or indicate that the 24 ports are not selected or for which no description information is sent.
[0057] In another example, the transmitting end device may determine the M port groups from N ports, which are antenna ports.
[0058] For example, N is 32 and M is 8. As shown in FIG4 , the transmitting end device can divide all or part of the 32 ports into 8 groups, such as port group 0, port group 1, port group 2, port group 3, port group 4, port group 5, port group 6, and port group 7, each of which includes 4 ports. Then, description information corresponding to each of the 8 groups of ports is generated, i.e., the reference signal configuration information is generated. The number of ports included in each group can be the same or different. Furthermore, at least one port differs from another port group.
[0059] In some embodiments, the description information includes at least one of the following: resource information, sequence information, power information, transmission configuration indication information, waveform information, and processing mode indication information.
[0060] (1) Resource information
[0061] The resource information may include resource locations used to describe the reference signals transmitted by the M ports or M port groups. For example, in a 5G communication system, the resource locations may be determined by time slot locations, orthogonal frequency-division multiplexing (OFDM) symbol locations, or subcarrier locations.
[0062] In some embodiments, the resources occupied by different antenna ports may be different.
[0063] In one possible implementation, the M ports include at least a first port and a second port, and the resources occupied by the reference signal transmitted on the first port are greater than or equal to the resources occupied by the reference signal transmitted on the second port. That is, the resources used by the reference signals transmitted on some ports are greater than or equal to the resources used by the reference signals transmitted on other ports. The reference signals provided in this disclosure include various types of reference signals, such as channel state information reference signals, demodulation reference signals, phase tracking reference signals, and paging reference signals.
[0064] Exemplarily, the value of N is 32, and the value of M is 2. The transmitting end device can select two ports from the 32 ports, as shown in FIG5 . One of the two ports, namely port 51, occupies all or part of the subcarriers in one OFDM symbol to send a reference signal, and the other port, namely the first port 52, occupies all or part of the subcarriers in two OFDM symbols to send a reference signal. In addition, the resources occupied by the reference signal transmitted on the first port are greater than or equal to the resources occupied by the reference signal transmitted on the second port. Among them, the ports can occupy resources through time division, frequency division, or code division, and the resources occupied by different ports can be different depending on the wireless channel conditions and system load conditions.
[0065] In some embodiments, the resources occupied by the reference signal transmitted on the first port are greater than or equal to the resources occupied by the reference signal transmitted on the second port, including at least one of the following: the number of time domain symbols occupied by the reference signal transmitted on the first port is greater than or equal to the number of time domain symbols occupied by the reference signal transmitted on the second port; and the number of subcarriers occupied by the reference signal transmitted on the first port is greater than or equal to the number of subcarriers occupied by the reference signal transmitted on the second port.
[0066] That is, the number of time domain symbols occupied by some ports is greater than or equal to the number of time domain symbols occupied by other ports. The number of frequency domain subcarriers occupied by some antenna ports is greater than or equal to the number of frequency domain subcarriers occupied by other antenna ports.
[0067] In another possible implementation, the M port groups include at least a first port group and a second port group, and the resources occupied by the reference signals transmitted on the first port group are greater than or equal to the resources occupied by the reference signals transmitted on the second port group. That is, the resources used by the reference signals transmitted on some port groups are greater than or equal to the resources used by the reference signals transmitted on other port groups. The reference signals provided in the present disclosure include multiple types of reference signals, such as channel state information reference signals, demodulation reference signals, phase tracking reference signals, and paging reference signals.
[0068] Exemplarily, the value of N is 32, and the value of M is 2. The transmitting end device can divide all or part of the 32 ports into two port groups, for example, divide all the subports of the 32 ports into two port groups, each group including 16 antenna ports. As shown in Figure 5, one of the two port groups, namely port group 51, occupies all or part of the subcarriers in one OFDM symbol to send a reference signal, and the other port group, namely port group 52, occupies all or part of the subcarriers in two OFDM symbols to send a reference signal. In addition, the resources occupied by the reference signal transmitted on the first port group are greater than or equal to the resources occupied by the reference signal transmitted on the second port group. Among them, the resources can be occupied by each port group through time division, frequency division, or code division, and the resources occupied by different port groups may be different according to the wireless channel conditions and system load conditions.
[0069] In some embodiments, the resources occupied by the reference signal transmitted on the first port group are greater than or equal to the resources occupied by the reference signal transmitted on the second port group, including at least one of the following: the number of time domain symbols occupied by the reference signal transmitted on the first port group is greater than or equal to the number of time domain symbols occupied by the reference signal transmitted on the second port group, and the number of subcarriers occupied by the reference signal transmitted on the first port group is greater than or equal to the number of subcarriers occupied by the reference signal transmitted on the second port group.
[0070] That is, the number of time domain symbols occupied by some port groups is greater than or equal to the number of time domain symbols occupied by other port groups. The number of frequency domain subcarriers occupied by some antenna port groups is greater than or equal to the number of frequency domain subcarriers occupied by other antenna port groups.
[0071] In some embodiments, a port or a port group occupies multiple time domain symbols, and a bandwidth occupied by a first time domain symbol among the multiple time domain symbols is greater than or equal to a bandwidth occupied by a second time domain symbol.
[0072] For example, as shown in FIG6 , the same port or port group, i.e., port (group) 61, occupies two OFDM symbols, and the bandwidth occupied by the first OFDM symbol is greater than or equal to the bandwidth occupied by the second OFDM symbol. The number or position of subcarriers occupied in each OFDM symbol may be different.
[0073] In some embodiments, the M ports include at least a first port and a second port, and the frequency hopping step length of the first port is greater than or equal to the frequency hopping step length of the second port. That is, the frequency hopping step lengths of some of the M ports are greater than or equal to the frequency hopping step lengths of other ports.
[0074] In some embodiments, the M port groups include at least a first port group and a second port group, and the frequency hopping step size of the first port group is greater than or equal to the frequency hopping step size of the second port group. That is, the frequency hopping step sizes of some of the M port groups are greater than or equal to the frequency hopping step sizes of other port groups.
[0075] Exemplarily, as shown in FIG7 , port or port group 71 occupies all or part of the subcarriers of 2 OFDM symbols, and uses frequency hopping between different symbols to determine the subcarrier position, and its frequency hopping step is greater than or equal to port or port group 72 .
[0076] (2) Sequence information
[0077] The sequence information of the reference signal transmitted on each port or port group may include the sequence generation method, sequence length, sequence content, etc. The reference signals provided in the present disclosure include various types of reference signals, such as channel state information reference signals, demodulation reference signals, phase tracking reference signals, and paging reference signals.
[0078] Sequence generation methods include maximum length linear feedback shift register sequence (also known as m-sequence), Gold Codes (also known as Gold sequence), CHU sequence (Chu sequence), Zadoff-Chu sequence (also known as ZC sequence), chirped pulse sequence (also known as CHIRP sequence), methods calculated and searched according to specific criteria, methods that obtain output through linear or nonlinear processing of specific inputs, methods based on processing of some useful data bits, and other possible methods.
[0079] In one example, the number of subcarriers occupied by a port or a port group in an OFDM symbol is 512, and the reference signal transmitted on the port or the port group corresponds to sequence information of a signal sequence with a sequence length of 512.
[0080] In another example, the number of subcarriers occupied by a port or a port group in an OFDM symbol is 512. The reference signal transmitted on the port or the port group may correspond to sequence information of four signal sequences with a total sequence length of 512. The length of each sequence in the four reference signal sequence information may be the same or different. For example, the four reference signal sequence information may be sequence information of four sequences with a length of 128.
[0081] In another example, as shown in Figure 8, a port or port group occupies all or part of the subcarriers on two OFDM symbols, and the sequence information in each OFDM symbol can be different. For example, the sequence generation method is different, such as using an m-sequence in the first OFDM symbol and a CHU sequence in the second OFDM symbol.
[0082] In another example, a port or a port group occupies all or part of the subcarriers on two OFDM symbols, and the sequence length on each OFDM symbol can be different, for example, the sequence length on the first OFDM symbol is 512, and the sequence length on the second OFDM symbol is 256.
[0083] In some embodiments, the M ports include at least a first port and a second port, and the length of a sequence used by a reference signal transmitted on the first port is greater than or equal to the length of a sequence used by a reference signal transmitted on the second port. That is, the length of a sequence used by a reference signal transmitted on some of the M ports is greater than or equal to the length of a sequence used by a reference signal transmitted on other ports.
[0084] In some embodiments, the M port groups include at least a first port group and a second port group, and the length of the sequence used by the reference signal transmitted on the first port group is greater than or equal to the length of the sequence used by the reference signal transmitted on the second port group. That is, the length of the sequence used by the reference signal transmitted on some of the M port groups is greater than or equal to the length of the sequence used by the reference signal transmitted on other port groups. The reference signals provided in the present disclosure include multiple types of reference signals, such as channel state information reference signals, demodulation reference signals, phase tracking reference signals, paging reference signals, etc.
[0085] Exemplarily, reference signals transmitted on different port groups may use different sequences, and the sequence lengths corresponding to different port groups may be different. As shown in Figure 9, the sequence of the reference signal transmitted on port or port group 91 includes an m-sequence and a CHU sequence, and the sequence of the reference signal transmitted on port or port group 92 is a Gold sequence. Furthermore, the length of the sequence used by the reference signal transmitted on port or port group 91 is greater than or equal to the length of the sequence used by the reference signal transmitted on port or port group 92.
[0086] (3) Power information
[0087] The power information includes a description of the M ports or M port groups sending reference signals on the used resources. The reference signals provided in the present disclosure include various types of reference signals, such as channel state information reference signals, demodulation reference signals, phase tracking reference signals, and paging reference signals.
[0088] In one possible implementation, the M ports include at least a first port and a second port, and the power of a reference signal transmitted on the first port is greater than or equal to the power of a reference signal transmitted on the second port. That is, the power used for reference signals transmitted on some of the M ports is greater than or equal to the power used for reference signals transmitted on other ports.
[0089] Exemplarily, the M ports include at least port A and port B, and the power of the reference signal transmitted on port A is greater than or equal to the power of the reference signal transmitted on port B. Alternatively, a power adjustment amount of the reference signal transmitted on port A is greater than or equal to the power adjustment amount of the reference signal transmitted on port B.
[0090] In some embodiments, the reference signal for measuring path loss of the reference signal transmitted on the first port is different from the reference signal for measuring path loss of the reference signal transmitted on the second port. Exemplarily, the M ports include at least port A and port B, the reference signal for measuring path loss of the reference signal transmitted on port A is reference signal R1, and the reference signal for measuring path loss of the reference signal transmitted on port B is reference signal R2.
[0091] In another possible implementation, the M port groups include at least a first port group and a second port group, and the power of the reference signal transmitted on the first port group is greater than or equal to the power of the reference signal transmitted on the second port group. That is, the power used for the reference signals transmitted on some of the M port groups is greater than or equal to the power used for the reference signals transmitted on other port groups.
[0092] Exemplarily, the M port groups include at least port group GA and port group GB, and the power of the reference signal transmitted on port group GA is greater than or equal to the power of the reference signal transmitted on port group GB. Alternatively, the power adjustment amount of the reference signal transmitted on port group GA is greater than or equal to the power adjustment amount of the reference signal transmitted on port group GB.
[0093] In some embodiments, the reference signal for measuring the path loss of the reference signal transmitted on the first port group is different from the reference signal for measuring the path loss of the reference signal transmitted on the second port group. Exemplarily, the M port groups include at least port group GA and port group GB. The reference signal for measuring the path loss of the reference signal transmitted on port group GA is reference signal R1, and the reference signal for measuring the path loss of the reference signal transmitted on port group GB is reference signal R2.
[0094] In some embodiments, a port or a port group occupies multiple time domain symbols, and the transmission power or power adjustment amount on a first time domain symbol among the multiple time domain symbols is greater than or equal to the transmission power or power adjustment amount on a second time domain symbol.
[0095] In one example, a port or a port group occupies at least two OFDM symbols, and in the two OFDM symbols, the transmission power or the power adjustment amount on one OFDM symbol is greater than or equal to the transmission power or the power adjustment amount on the other OFDM symbol.
[0096] In some embodiments, a port or a port group occupies multiple subcarriers, and the transmission power or power adjustment amount on a first subcarrier among the multiple subcarriers is greater than or equal to the transmission power or power adjustment amount on a second subcarrier.
[0097] (4) Transmission configuration instruction information
[0098] The transmission configuration indication information may be used to indicate channel-related parameters corresponding to each port or port group, such as delay, frequency deviation, Doppler shift, angle, moving speed, spatial filtering, beamforming, etc. Thus, when a transmitting device sends the transmission configuration indication information to a receiving device, the receiving device may determine channel-related parameters such as delay, frequency deviation, Doppler shift, angle, moving speed, spatial filtering, and beamforming based on the transmission configuration indication information.
[0099] In some embodiments, a port or a port group corresponds to at least one transmission configuration indication information, and each transmission configuration indication information acts on a preset or specific resource area.
[0100] In one example, each of the M ports corresponds to one or more transmission configuration indications. Alternatively, each of the M port groups corresponds to one or more transmission configuration indications. As shown in FIG10 , port or port group 101 corresponds to indications for transmission configurations A and B, and port or port group 102 corresponds to indications for transmission configuration C.
[0101] In another example, for any port among the M ports, such as port A, the transmitting end device may divide the resources occupied by port A into T parts, wherein each resource or a combination of multiple resources corresponds to one or more transmission configuration indication information. Alternatively, for any port group among the M port groups, such as port group GA, the transmitting end device may divide the resources occupied by port group GA into T parts, wherein each resource or a combination of multiple resources corresponds to one or more transmission configuration indication information, where T is a positive integer. As shown in FIG11 , the port or port group 111 is divided into two parts, and each resource corresponds to the indication information of transmission configuration A and transmission configuration B.
[0102] In some embodiments, the reference signal configuration information is carried in at least one control message.
[0103] Exemplarily, the reference signal configuration information can be carried by Y data control information (DCI), where Y is an integer greater than or equal to 1, and its value can be a default configuration or determined by negotiation between the sender and the receiver, for example, sent by DCI carried by two physical downlink control channels (PDCCH).
[0104] (5) Waveform information
[0105] Among them, the waveform information of the reference signal transmitted on each port or port group may include information for indicating waveform generation methods such as OFDM, discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM), orthogonal time frequency space (OTFS) modulation, code division multiple access (CDMA), and single carrier.
