[0075] In some embodiments, data, information, etc., may be obtained with the user's consent.

[0076] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0077] During communication, the terminal can determine the location of the resource element (RE) corresponding to the reference signal resource. Alternatively, the terminal can determine the location of the RE corresponding to the port.

[0078] In some embodiments, when a base station configures Channel State Information-Reference Signal (CSI-RS) resources, the Radio Resource Control (RRC) signaling includes the following information:

[0079] Frequency domain resource allocation information;

[0080] Number of ports;

[0081] Starting symbol position;

[0082] Code Division Multiplexing (CDM) type;

[0083] density;

[0084] Frequency domain start position and bandwidth.

[0085] In some embodiments, frequency domain resource allocation information can be used to indicate which subcarriers each port of the CSI-RS occupies.

[0086] In some embodiments, the CDM type includes at least one of the following:

[0087] No CDM;

[0088] Frequency Division (FD)-CDM2: Two ports occupy the same two subcarriers, and the two subcarriers are on the same symbol. Figure 1a is a schematic diagram of a CDM type. As shown in Figure 1a, RE represents one subcarrier on a symbol. RE#1 and RE#2 in Figure 1a are two subcarriers on the same symbol. RE#1 and RE#2 can be used for the transmission of reference signals for both ports. Each port corresponds to two subcarriers, but the codes corresponding to the two ports are different, i.e., code division.

[0089] CDM4-FD2-Time Division (TD) 2: Four ports occupy the same four REs, which are allocated across two symbols. Figure 1b is a schematic diagram of a CDM type. As shown in Figure 1b, an RE represents one subcarrier on one symbol. RE#1 and RE#2 are two subcarriers on the same symbol, and RE#3 and RE#4 are two subcarriers on another symbol. The four ports can occupy the four REs in Figure 1b, namely RE#1, RE#2, RE#3, and RE#4, but correspond to different codes.

[0090] CDM8-FD2-TD4: As shown in Figure 1c, Figure 1c is a schematic diagram of a CDM type.

[0091] In some embodiments, density refers to determining the frequency domain density of the subcarriers occupied by the reference signal after determining the subcarriers based on the frequency domain resource location. For example, if the density is 3, then the subcarriers are repeated 3 times at equal intervals within a resource block (RB). For instance, if the frequency domain resource location determines that 2 of the 1-12 subcarriers are occupied, and the density is 3, then the subcarriers occupied in an RB are 2, 6, and 10, and each RB occupies these 3 subcarriers. If the density is 1, then the subcarriers are repeated once per RB. For instance, if the frequency domain resource location determines that 2 of the 1-12 subcarriers are occupied, and the density is 1, then the subcarriers occupied in an RB are 2, and each RB occupies this 1 subcarrier.

[0092] In some embodiments, the frequency domain start position and bandwidth can be understood as the starting RB position occupied by the reference signal and the number of RBs occupied.

[0093] In some embodiments, the terminal can determine the location of the RE corresponding to the reference signal resource based on the above RRC information, and can also determine the location of the RE corresponding to each port.

[0094] In some embodiments, for each reference signal resource, the base station sends RRC signaling to configure the above information, so that the terminal can obtain the RE resource corresponding to each reference signal resource and receive the measurement reference signal. However, the RE resources corresponding to different reference signal resource identifiers need to be configured separately. Furthermore, for different terminals, the base station aims to send the same reference signal resource for measurements by multiple terminals, thereby reducing the overhead of reference signal resources.

[0095] In some embodiments, under a very large MIMO scenario, as shown in Figure 1d, near-field effects and spatial non-stationarity cause significant differences in signal strength when signals transmitted from different ports on the base station reach the terminal. Figure 1d is a schematic diagram of different UEs transmitting signals to each other via different ports of the base station. For example, when UE1 and UE3 transmit signals to each other via port 0, since UE1 is closer to port 0 and UE3 is farther away, the signal strength of the signal transmitted between UE1 and port 0 is greater than that between UE3 and port 0, and the difference in signal strength is significant. In this embodiment, the base station can use different ports to transmit reference signals for different terminals. For example, still using Figure 1d, UE1 can transmit signals to each other via port 0, and UE3 can transmit signals to each other via port 15, thereby reducing the difference in signal strength. However, different reference signal resources need to be configured separately for different terminals. For example, the reference signal resources corresponding to port 0 are configured for UE1, and the reference signal resources corresponding to port 15 are configured for UE3, resulting in a large reference signal resource overhead.

[0096] Therefore, this disclosure provides a communication method in which a terminal receives first information, which can be used to determine a second port from a first port. The first port is determined based on the second information, and the second port is used to receive a reference signal. In other words, the second information can first determine the first port, and then the terminal can determine the second port from the first port based on the first information. Thus, different terminals can determine their respective second ports, thereby enabling the configuration of the same reference signal resource for different terminals, thereby reducing reference signal resource overhead and saving resources.

[0097] Figure 1e is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.

[0103] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0108] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0109] In step S2101, network device 102 sends second information to terminal 101.

[0110] In some embodiments, terminal 101 receives second information sent by network device.

[0111] In some embodiments, the second information is information about reference signal resources. The terminal can determine the information about the reference signal resources based on the second information.

[0112] It is understood that the terminal can determine the information of the reference signal resource based on the second information sent by the network device, or it can determine the information of the reference signal resource based on a predefined method of the protocol. That is to say, step S2101 is optional.

[0113] In some embodiments, step 2101 can be omitted, and the terminal can determine the information of the reference signal resource based on a protocol-predefined method. That is, the protocol can predefine the information of the reference signal resource, and the terminal can determine the information of the reference signal resource from the protocol.

For example, the reference signal resource may be a single-port reference signal resource, and the frequency domain resource allocation information may be used to indicate the frequency domain location corresponding to the reference signal resource, such as indicating which subcarriers the reference signal resource occupies. As another example, the reference signal resource may be a multi-port reference signal resource, and the frequency domain resource allocation information may be used to indicate the frequency domain location corresponding to each port of the reference signal resource, such as indicating which subcarriers each port of the reference signal resource occupies. Taking the reference signal resource as a CSI-RS resource as an example, the frequency domain resource allocation information may be used to indicate which subcarriers each port of the CSI-RS occupies.

[0116] Optionally, the information about the reference signal resource may include the number of ports. For example, if the reference signal resource is a single-port reference signal resource, the number of ports can be 1. Or, if the reference signal resource is a multi-port reference signal resource, the number of ports can be greater than 1.

[0117] Optionally, the information of the reference signal resource may include the start symbol position. For example, the terminal may begin receiving the reference signal on the reference signal resource at the start symbol position. The information of the reference signal resource may also include other time-domain information, such as the end symbol position or the number of symbols, etc., which are not limited in this disclosure.

[0118] Optionally, the information of the reference signal resource may include the CDM type. For example, the CDM type may be as shown in the above embodiments, and reference may be made to the CDM types shown in Figures 1a to 1c, but this disclosure is not limited thereto.

[0119] Optionally, the information about the reference signal resource may include the density of the subcarriers occupied by the reference signal resource within the frequency domain resource. For example, if the density is 3, it can be repeated 3 times at equal intervals within a RB. For instance, if the location of the occupied subcarriers is determined based on the frequency domain resource location (e.g., 2 out of 12), and the density is 3, then the occupied subcarriers in a RB are 2, 6, and 10, and these 3 subcarriers are occupied in each RB. If the density is 1, it is repeated once per RB. For instance, if the location of the occupied subcarriers is determined based on the frequency domain resource location (e.g., 2 out of 12), and the density is 1, then the occupied subcarriers in a RB are 2, and this 1 subcarrier is occupied in each RB.

[0120] It is understood that the specific values ​​mentioned above are merely illustrative and are not intended to be limiting.

[0121] Optionally, the information about the reference signal resource may include the start position of the resource block. For example, the terminal may begin receiving reference signals on the reference signal resource at the start position of the resource block.

[0122] Optionally, the information about the reference signal resource may include the resource block bandwidth. For example, the terminal may receive a reference signal on the reference signal resource on the resource block based on the start position of the resource block and the bandwidth of the resource block.

[0123] In some embodiments, the terminal can determine a first port based on second information. The terminal can then determine a second port from the first port for receiving a reference signal. For example, different terminals can receive the same second information and determine the same first port, but each terminal can determine a different second port from the first port. That is, different terminals can configure the same reference signal resource, but by determining different second ports, conflicts when receiving the reference signal can be avoided, thereby saving resources and reducing the overhead of the reference signal resource.

[0124] In some embodiments, the second information may be an RRC, or in other words, the second information may be carried by an RRC, and this disclosure does not limit this.

[0125] In some embodiments, the name of the second information is not limited; for example, the second information may be "configuration information" or the like.

[0126] In step S2102, network device 102 sends first information to terminal 101.

[0127] In some embodiments, terminal 101 receives first information sent by network device 102.

[0128] In some embodiments, the first information is used to determine the second port from the first port.

[0129] In some embodiments, the first information can be used to indicate the number of second ports. That is, the first information can indicate the number of second ports so that the terminal can determine the second ports from the first ports based on the number of second ports.

[0130] For example, assuming the number of first ports is N and the number of second ports is M, the terminal can default the first M ports out of the N first ports to the M second ports. Here, M and N are positive integers, and M is less than or equal to N. The N first ports can be sorted from low frequency to high frequency, so the first M first ports can be the first ports with relatively lower frequencies. As another example, the N first ports can be sorted from low sign position to high sign position, so the first M first ports can be the first ports with relatively low sign positions. It is understood that the N first ports can also be sorted from high frequency to low frequency, or from high sign position to low sign position, or from high to low or low to high according to other parameters; this disclosure does not limit this.

[0131] In some embodiments, if the first information indicates the number of second ports, assuming the number of first ports is N, and M can take values ​​from 1 to N, the number of bits in the first information can be log2(N) rounded up. For example, if N is 48, then the first information requires 6 bits.

[0132] In some embodiments, if the first information indicates the number of the second ports, assuming the number of the first ports is N, and the possible values ​​of M are not 1 to N, assuming N is 48, the value of M can be 1, 2, 4, 8, 16, 24, 32, a total of 7 optional values, then the number of bits required for the first information can be log2(7) rounded up, then the first information requires 3 bits.

[0133] In some embodiments, the first information may also be used to indicate the number of the first second port in the first port.

[0134] For example, assuming each first port corresponds to a number, if the number of first ports N is 48, then the first port numbers can be #1 to #48, or #0 to #47. Taking the first port numbers #1 to #48 as an example, if the first information indicates that the first second port's number among the first ports is #1, and the number of second ports is 3, then the second ports can be first port #1, first port #2, and first port #3 respectively. That is, first port #1, first port #2, and first port #3 can be identified as second ports.

[0135] For example, if the first information indicates that the number of the first second port in the first port is #1, and the number of second ports is 3, then the second ports can be the first port #1, the first port #3, and the first port #5. That is to say, the first port #1, the first port #3, and the first port #5 can be identified as the second ports.

[0136] In other words, the second port can be multiple consecutive ports from the first port, or it can be multiple non-consecutive ports.

[0137] In some embodiments, the first information may also be used to indicate the interval between different second ports, for example, to indicate the number of first ports that exist between different second ports.

[0138] For example, if the first information indicates that the number of second ports is 3, the number of the first second port in the first port is #2, and the interval between different second ports is 1 first port, then the second ports can be first port #2, first port #4, and first port #6.

[0139] For example, if the first information indicates that the number of the first second port in the second port is #3, and the interval between different second ports is 3 first ports, assuming there are a total of 48 first ports, then the second ports can be: first port #3, first port #7, first port #11, ..., first port #43, first port #47. That is to say, the first information does not necessarily indicate the number of first ports; based on the interval between different first ports, multiple second ports can be determined from the first ports.

[0140] For example, the first information can indicate the number of second ports and the interval between different second ports, while the number of the first second port in the first port can be determined based on the protocol specifications or by default rules. For example, the first second port can be defaulted to number #1 in the first port, that is, the first first port can be determined as the first second port.

[0141] In some embodiments, the number of the first port may be configured by the network device, or may be specified in the protocol, or may be obtained by the terminal sorting from low frequency to high frequency, or from low symbol position to high symbol position. This disclosure does not limit this.

[0142] In some embodiments, the first information is used to indicate the number of the second port in the first port. That is, the first information can indicate the number of the second port in the first port so that the terminal can determine the second port based on the number of the second port in the first port.

[0143] For example, assuming the number of first ports is N, the first information can include N bits, with each bit corresponding to one first port. If a bit takes the first value, it means that the first port corresponding to that bit can be identified as a second port. If a bit takes the second value, it means that the first port corresponding to that bit can not be identified as a second port. The number of the first port corresponding to the bit with the first value in the first port is the same as the number of the second port in the first port.

[0144] In some embodiments, the first information includes at least one of the following: RRC; Media Access Control-Control Element (MAC CE); Downlink Control Information (DCI).

[0145] Optionally, the first information may include RRC. For example, for a periodic reference signal resource, the first information may include RRC, but is not limited to this.

[0146] Optionally, the first information may include MAC CE. For example, for a semi-persistent reference signal resource, the first information may include MAC CE, but is not limited thereto.

[0147] Optionally, the first information may include DCI. For example, for aperiodic reference signal resources,

[0148] The first information may include, but is not limited to, DCI.

[0149] Optionally, before the DCI, there may be an RRC or MAC CE that provides several possible configurations for the second port, while the DCI only indicates one of the possible configurations, which can also reduce the number of bits of the second information.

[0150] In some embodiments, the second port includes at least one set of second ports, and the first information is used to determine at least one set of second ports from the first port. For example, one set of second ports has 4 ports, another set has 8 ports, and yet another set has 16 ports, etc., to name a few.

[0151] In some embodiments, the name of the first information is not limited, and it may be, for example, "configuration information".

[0152] In step S2103, terminal 101 sends the measurement value corresponding to the second port to network device 102.

[0153] In some embodiments, the terminal determines a second port and a corresponding measurement value, thereby enabling it to send the measurement value to the network device. For example, the terminal can receive and measure a reference signal at the second port to obtain the measurement value corresponding to the second port.

[0154] In some embodiments, the second port may include at least one set of second ports, and the terminal may send measurement values ​​corresponding to at least one set of second ports. For example, the terminal may send measurement values ​​corresponding to one set of second ports. As another example, the terminal may send multiple sets of measurement values ​​corresponding to different second ports; this disclosure does not limit this.

[0155] Optionally, the measurement value corresponding to the second port can be obtained by actually measuring the second port, or by actually measuring some ports in the second port and then using some algorithms to obtain the measurement values ​​corresponding to all ports in the second port. These algorithms can be interpolation algorithms, artificial intelligence (AI) / machine learning (ML) algorithms, etc., and this disclosure does not limit them.

[0156] In some embodiments, network device 102 receives the measurement value corresponding to the second port sent by terminal 101.

[0157] In some embodiments, the second port may include at least one set of second ports, and the network device may receive measurement values ​​corresponding to at least one set of second ports. For example, the network device may receive measurement values ​​corresponding to one set of second ports. As another example, the network device may receive measurement values ​​corresponding to multiple sets of second ports, each respectively.

[0158] Optionally, after receiving the measurement values ​​corresponding to multiple sets of second ports, the network device can select any set of second ports and perform uplink and downlink transmissions to the terminal based on the measurement values ​​of that set of second ports, and indicate the selected second port to the terminal.

[0159] In some embodiments, the measured values ​​include at least one of the following: Layer 1 reference signal received power (L1-RSRP); Layer 1 signal to interference plus noise ratio (L1-SINR); Layer 3 reference signal received power (L3-RSRP); Layer 3 signal to interference plus noise ratio (L3-SINR); Layer 3 Reference Signal Received Quality (L3-RSRQ); Channel State Information (CSI); Channel Quality Indicator (CQI); Precoding Matrix Indicator (PMI); RANK Indicator (RI).

[0160] In some embodiments, L1-RSRP and L1-SINR can correspond to beam measurement.

[0161] In some embodiments, L3-RSRP, L3-SINR, and L3-RSRQ can correspond to RRM radio resource management measurements, such as those used for mobility management.

[0162] In some embodiments, PMI, CQI, and RI can correspond to CSI measurements.

[0163] In some embodiments, PMI may include at least one of the following: a spatial (SD) basis; a frequency (FD) basis; an amplitude coefficient; a phase coefficient; and the location of the strongest amplitude coefficient.

[0164] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. The order of implementation is not limited. For example, step S2101 may be implemented as a standalone embodiment, but is not limited thereto. For example, the network device may send the first information first and then the second information, or it may send the second information first and then the first information, or it may send the first information and the second information simultaneously. That is, step S2101 may be implemented before step S2102, after step S2102, or together, but is not limited thereto.

[0165] In some embodiments, steps S2102 to S2103 are optional and may be omitted or substituted in different embodiments.

[0202] Figure 5 is a schematic diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5, this embodiment of the present disclosure relates to a communication method, which includes:

[0203] In step S5101, network device 102 sends first information to terminal 101.

[0204] In some embodiments, the above methods may include the methods of the embodiments related to the communication system 100, terminal 101, and network device 102, which will not be described again here.

[0205] This disclosure provides a method for configuring reference signal resources, as follows:

[0206] In some embodiments, the terminal receives second information sent by the base station, the second information being configuration reference signal resource information, and the second information including at least one of the following:

[0207] a) Frequency domain resource allocation: used to indicate which subcarriers each port of the reference signal (CSI-RS) occupies;

[0208] b) Number of ports;

[0209] c) Position of the starting symbol;

[0210] d) CDM type;

[0211] e) Density;

[0212] f) RB start position and bandwidth;

[0213] In some embodiments, first information is received, which is used to indicate second port information, and the second port information is used to indicate at least a portion of the first ports determined by the terminal based on the second information.

[0214] In some embodiments, the terminal determines the number of the first ports as N based on the second information, whereby the first information is used to indicate the number of ports corresponding to the second ports.

[0215] For example, if the number of first ports is N and the number of second ports is M, the number of bits required for the first information is log2(N) rounded up. For example, if N is 48, the number of bits required for the first information is 6 bits. Since the first information only indicates the number of second ports, which ports in the first set correspond to the second ports needs to be determined by default, such as the first M ports. The terminal has already determined the RE and code corresponding to each port based on the second information, and the port numbers are from low frequency to high frequency, and from low sign position to high sign position. Of course, the first information can also indicate the port number of the first port, i.e., the M consecutive ports starting from the first port.

[0216] Furthermore, in order to reduce the number of bits in the first information, the number of ports corresponding to the second port can be restricted from being 1 to N. For example, if N is 48, the value of M can be 1, 2, 4, 8, 16, 24, 32, etc. In this way, the number of bits in the first information only needs to indicate the possible values ​​of M.

[0217] In some embodiments, the terminal determines the number of the first ports as N based on the second information, whereby the first information is used to indicate the port number corresponding to the second port.

[0218] For example, if the number of ports is N, the number of bits required for the first piece of information is also N. For example, if N is 48, the number of bits required for the first piece of information is 48 bits. A '1' indicates that the port is included; otherwise, it indicates that the port is not included.

[0219] In some embodiments, the terminal obtains at least one of the following based on reference signal resources: L1 / 3-RSRP, L1 / 3-SINR, PMI, CQI, RI.

[0220] In some embodiments, L1-RSRP and L1-SINR correspond to beam measurements.

[0221] In some embodiments, L3-RSRP and L3-SINR correspond to RRM radio resource management measurements, such as those used for mobility management.

[0222] In some embodiments, PMI, CQI, and RI correspond to CSI measurements.

[0223] In some embodiments, the first information is at least one of RRC, MAC CE, and DCI.

[0224] In some embodiments, the second information is RRC.

[0225] In some embodiments, the first information may be RRC, i.e., reference signal resource for periodic.

[0226] In some embodiments, the first information may be MAC CE, i.e., a reference signal resource for semi-persistent signals.

[0227] In some embodiments, the first information may be DCI, i.e., reference signal resources for aperiodic.

[0228] In some embodiments, prior to the DCI, there may be an RRC or MAC CE providing several possible configurations for the second port, while the DCI only indicates one of these possible configurations, which can also reduce the number of bits in the first information.

[0229] In some embodiments, the first information indicates information about one or more second ports.

[0230] For example, one second port has 4 bytes, another has 8 bytes, and yet another has 16 bytes...

[0231] In some embodiments, the terminal feeds back at least one channel state information (CSI) corresponding to the second port information based on the second port information.

[0232] In some embodiments, CSI includes at least one of the following: PMI, RI, CQI.

[0233] In some embodiments, the PMI includes at least one of the following:

[0234] SD basis;

[0235] FD basis;

[0236] Amplitude coefficient;

[0237] Phase coefficient;

[0238] The position of the strongest amplitude coefficient.

[0239] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0240] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0241] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
