[0107] FIG1A is a schematic diagram illustrating the architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1A , a communication system 100 includes a terminal 101 and a network device 102 .

[0110] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0115] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0116] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0117] In a communication system, such as a 5G NR system, uplink sounding reference signals (SRS) are classified according to the number of ports, and can be divided into single-port SRS or multi-port SRS.

[0118] It is understood that the SRS may be periodic, aperiodic, or semi-persistent. In some embodiments, the SRS may be narrowband or broadband.

[0119] In some embodiments, uplink SRS parameters are configured by the network device to the terminal. The configured parameters include, for example, the number of ports, frequency domain resource location, time domain resource location, sequence, sequence cycle offset, etc.

[0120] In some embodiments, the SRS may support mapping on all orthogonal frequency division multiplex (OFDM) symbols in an uplink timeslot in R17.

[0121] In some embodiments, the configuration of the SRS port may be implemented based on code division multiplexing or frequency division multiplexing.

[0122] For example, similar to the LTE system, different phase shifts of the Zadoff-Chu (ZC) sequence are used to obtain orthogonal sequences for transmitting SRS. In addition, frequency domain orthogonality is achieved by using alternate subcarrier mapping in the frequency domain, so that the SRS can be mapped to one subcarrier or every three subcarriers.

[0123] In some embodiments, the number of SRS resources supported may be configured through high-level parameters.

[0124] Exemplary includes, for example, the number of SRS ports (number of Sounding Reference Signal ports, nrofSRS-Ports).

[0125] In some embodiments, the number of ports supported by one SRS resource is N, where N can be one of {1, 2, 4, 8}, and N is based on the nrofSRS-Ports configuration.

[0126] In some embodiments, the number of OFDM symbols occupied by an SRS resource in the time domain is M, where M can be one of {1, 2, 4, 8, 10, 12, 14}, and M is configured based on nrofSRS-Ports.

[0127] For example, Figure 1B is a schematic diagram of SRS time-frequency domain distribution according to an embodiment of the present disclosure. As shown in Figure 1B, SRS resource 1 occupies 1 OFDM symbol, SRS resource 2 occupies 4 OFDM symbols, and SRS resource 3 occupies 2 OFDM symbols.

[0128] It is understood that the main benefits of an SRS resource occupying multiple OFDM symbols are as follows: improving the coverage of the SRS parameter signal and / or supporting frequency hopping within a time slot. When the SRS frequency hopping function is enabled, an SRS resource occupies an OFDM symbol within a time slot, but the corresponding frequency domain occupies different subbands.

[0129] In some embodiments, the SRS is characterized by a comb structure in the frequency domain, that is, the SRS resource is not mapped to a continuous subcarrier.

[0130] In some embodiments, the comb structure is based on comb representation, and the value of comb can be 2 or 4. When comb is equal to 2 or 4, different ports of a 4-port SRS resource in the NR system can be set on different subcarriers, that is, the subcarrier offsets of different ports can be different under the same comb parameter.

[0131] In some embodiments, R18 introduces an 8-port SRS, which can support both time division multiplexing (TDM) mapping and non-TDM mapping based on corresponding configuration parameters (including, for example, ports8tdm).

[0132] It is understood that, in the case of a non-TDM mapping mode, any of the following cyclic shift configurations may be used:

[0133] Different cyclic shift multiplexing is allocated on the same comb value of 2 (comb-2);

[0134] The different comb offset values ​​(comb offset) allocated when the comb value is 4 (ie comb-4) and the corresponding different cyclic shift multiplexing are combined;

[0135] The different comb resource offset values ​​allocated when the comb value is 8 (ie comb-8) are combined with the corresponding different cyclic shift multiplexing.

[0136] In some embodiments, in a TDM mapping manner, if a group of 8-port SRSs needs to occupy s OFDM symbols, corresponding SRS subsets are defined based on s, and different SRS port subsets occupy different symbols.

[0137] Exemplarily, it is defined that when the value of s is 2, the SRS ports corresponding to the SRS subsets are {0, 1, 4, 5} and {2, 3, 6, 7} respectively.

[0138] In some embodiments, similar to the LTE system, the SRS sequence in the NR system is also generated based on the ZC sequence. However, the difference is the sequence length. It is based on the bandwidth configured for a terminal is generated instead of the system bandwidth, as shown in Equation 1 below:

[0139] Among them, the values ​​of n and l′ can be as follows:

[0140] in, m SRS,b Determined based on the corresponding protocol table, Indicates the number of subcarriers contained in a physical resource block (PRB), the value of comb (K TC ) can be configured based on high-level signaling, including, for example, transmission comb resource signaling (transmission Comb), and the configured value includes, for example: 2, 4 or 8, and the value of δ can be based on K TC Determine, for example: δ = log2(K TC ).

[0141] In some embodiments, for the cyclic shift α i and antenna port p i The relationship is based on the following formula 2:

[0142] In some embodiments, the bandwidth configured for the terminal The value of , when the high-level parameter nrofSRS-Ports is ports8tdm, can be expressed by the following formula 3:

[0143] In addition to the case where the high-level parameter nrofSRS-Ports is ports8tdm, The value of is 1.

[0144] In some embodiments, for the SRS cyclic shift number The value of is configured by high-level signaling (including, for example, transmission Comb). For example, the specific configuration content is shown in Table 1.

[0145] Table 1

[0146] Table 1 shows the corresponding relationship between the number of combs (ie, the value of KTC) and the most supportable number of cyclic shifts.

[0147] For example, K TC =4, the maximum number of cyclic shifts supported is expressed as K TC =2, the maximum number of cyclic shifts supported is expressed as K TC =8 when the maximum number of cyclic shifts supported is expressed as

[0148] In some embodiments, the SRS port capacity supported for different configured comb numbers is different, including, for example, when the comb value is 2, the SRS port capacity supported is 16 (2*8=16), and when the comb value is 4, the SRS port capacity supported is 48 (4*12=48).

[0149] In some embodiments, for SRS resources with different numbers of ports, the number of SRS cyclic shifts on each port is The mapping relationship between the actual allocated frequency domain subcarriers under different comb configurations can be expressed based on the following formula 4:

[0150] The range of the cyclic shift number of the SRS can be as follows:

[0151] For cyclic shift The value of can be determined based on the high-level parameter (transmission Comb). The maximum value can be determined based on Table 1.

[0152] In some embodiments, since the NR system supports a physical uplink shared channel (PUSCH) with N ports, N is any one of {1, 2, 4, 8}.

[0153] However, current terminals are typically equipped with only one or two transmit (Tx) antennas. Furthermore, to enhance uplink (UL) performance, there is an increasing demand for terminals equipped with more antennas. Therefore, the Multiple Input Multiple Output (MIMO) enhancements in Release 19 propose supporting terminals with three transmit antennas.

[0154] To support a terminal with three transmit antennas, codebook-based PUSCH transmission also requires a three-port SRS. Therefore, the present disclosure proposes a resource configuration method for acquiring a three-port SRS resource based on existing SRS resources.

[0155] Figure 2 is an interactive diagram of a resource configuration method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a resource configuration method, which includes:

[0156] Step S2101: Terminal 101 determines 3-antenna port SRS resources.

[0157] In some embodiments, the network device 102 configures 3-antenna port SRS resources.

[0158] In some embodiments, 3-antenna port SRS resources are used for terminal 101 to transmit SRS resources based on 3 antenna ports.

[0159] It is understandable that the 3-antenna port SR resource can be referred to as the first SRS resource. The number of ports of the first SRS resource can be referred to as the first antenna port number, and the value of the first antenna port number is 3.

[0160] In some embodiments, the first SRS resource (i.e., 3-antenna port SRS resource) is determined based on the second SRS resource, and the second SRS resource is a plurality of SRS resources supporting the second number of antenna ports, wherein the second number of antenna ports includes at least one of 1 port, 2 ports, 4 ports, and 8 ports.

[0161] Exemplarily, the second resource is a plurality of SRS resources supporting the same number of antenna ports, for example, the second resource is two SRS resources supporting an antenna port number of 2. The second resource may also be a plurality of SRS resources supporting different numbers of antenna ports, for example, the second resource is one resource supporting an antenna port number of 2 and one resource supporting an antenna port number of 1.

[0162] In some embodiments, the terminal 101 determines based on one or more antenna port SRS resources among 1 antenna port SRS resource and 2 antenna port SRS resources.

[0163] In some embodiments, there is a mapping relationship between the antenna port corresponding to the SRS resource of each antenna port and each antenna port corresponding to the 3-antenna port SRS resource; the SRS resource of each antenna port is the SRS resource of each antenna port in the 1-antenna port SRS resource and the 2-antenna port SRS resource, or the SRS resource of each antenna port in the 2 2-antenna port resources.

[0164] In some embodiments, the terminal 101 determines the 3-antenna-port SRS resource based on one or more antenna-port SRS resources among the 1-antenna-port SRS resource and the 2-antenna-port SRS resource, including at least one of the following -A) and -B):

[0165] -A) The terminal 101 determines a 3-antenna-port SRS resource based on a 1-antenna-port SRS resource and a 2-antenna-port SRS resource.

[0166] -B) The terminal 101 determines a 3-antenna-port SRS resource based on a 2-antenna-port SRS resource.

[0167] Optionally, for -A), the terminal 101 determines a 3-antenna-port SRS resource based on one 1-antenna-port SRS resource and one 2-antenna-port SRS resource.

[0168] Optionally, for -B), the terminal 101 determines a 3-antenna-port SRS resource based on two 2-antenna-port SRS resources.

[0169] It can be understood that the terminal 101 determines the SRS resources of the 3 antenna ports based on one or more of the 1 antenna port SRS resources and the 2 antenna port SRS resources. Regardless of whether the -A) or -B) method is used to determine the SRS resources of the 3 antenna ports, the corresponding parameter configuration of the SRS resources involved is required.

[0170] In some embodiments, the SRS resources involved can be classified as follows according to their mapping relationship or collection relationship: SRS resources constituting 3-antenna port SRS resources (that is, one or more antenna port SRS resources among 1-antenna port SRS resources and 2-antenna port SRS resources), SRS resources of 3 antenna ports, and a set of SRS resources of 3 antenna ports.

[0171] Therefore, the corresponding parameter configuration of the SRS resources mentioned above can be performed from the following configuration levels:

[0172] Parameter configuration is performed based on each 1-antenna-port SRS resource and / or 2-antenna-port SRS resource, parameter configuration is performed based on 3-antenna-port SRS resources, and parameter configuration is performed based on a 3-antenna-port SRS resource set.

[0173] Exemplarily, parameter configuration is performed based on each 1-antenna port SRS resource and / or 2-antenna port SRS resource, which can be understood as performing a first parameter configuration for each SRS resource in the 1-antenna port SRS resource and the 2-antenna port SRS resource (that is, each SRS resource that constitutes the 3-antenna port SRS resource in the above-A) case), and / or performing a first parameter configuration for the SRS resources of the antenna ports in the 2 2-antenna port resources (that is, each SRS resource that constitutes the 3-antenna port SRS resource in the above-b) case).

[0174] Exemplarily, parameter configuration is performed based on a 3-antenna-port SRS resource, which can be understood as performing a second parameter configuration on the 3-antenna-port SRS resource, wherein the second parameter of the 3-antenna-port SRS resource configuration has a mapping relationship with the SRS resource of each antenna port in the 1-antenna-port SRS resource and the 2-antenna-port SRS resource (for example, a mapping relationship between one 1-antenna-port SRS resource and one 2-antenna-port SRS resource and the second parameter of one 3-antenna-port SRS resource), or the second parameter of the 3-antenna-port SRS resource configuration has a mapping relationship with the SRS resource of the antenna port in two 2-antenna-port resources (for example, a mapping relationship between two 2-antenna-port SRS resources and the second parameter of one 3-antenna-port SRS resource).

[0175] Exemplarily, parameter configuration is performed based on a set of SRS resources for three antenna ports. This can be understood as performing a third parameter configuration on the set of SRS resources for three antenna ports in a set-specific manner. It can be understood that the set of SRS resources for three antenna ports includes the SRS resources that constitute the SRS resources for the three antenna ports. For example, the set includes the SRS resources for each antenna port in the SRS resources for one antenna port and the SRS resources for two antenna ports, or includes the SRS resources for the antenna ports in two sets of the SRS resources for two antenna ports.

[0176] In some embodiments, the first parameter, the second parameter, and the third parameter may be of the same or different categories.

[0177] In some embodiments, when the first parameter, the second parameter, and the third parameter are of the same category, the corresponding parameter values ​​may be the same or different.

[0178] In some embodiments, the first parameter, the second parameter, and the third parameter include at least one of the following parameters: resource type, power control parameter, frequency hopping sequence parameter, frequency hopping parameter, sequence ID, or spatial relationship.

[0179] Optionally, the resource type includes at least one of the following: a periodic SRS resource type, an aperiodic SRS resource type, or a semi-persistent SRS resource type.

[0180] Optionally, when the resource type is a periodic SRS resource (PSRS) type or a non-periodic SRS resource (SP-SRS) type, a resource period, a start time or an SRS periodicity and offset (SRS-Periodicity And Offset) is configured for the SRS resource.

[0181] Optionally, the power control parameter includes at least one of the following: a parameter for indicating redundancy (eg, an alpha parameter), a parameter for indicating a reference power level (eg, a P0 parameter), or a physical layer reference signal (PL-RS).

[0182] Optionally, the frequency hopping sequence parameter includes at least one of the following: group hopping or sequence hopping.

[0183] Optionally, the frequency hopping parameter includes at least one of the following: frequency hopping (freqhopping), frequency domain position (freqDomainPosition), or frequency domain shift (frqeDomainShift).

[0184] Optionally, the spatial relationship, also referred to as spatial relation information (sptialRelationInfo), includes at least one of the following: transmission configuration indication state information (including, for example, SRS_TCI_State_r17), downlink or joint transmission and reception state report (SRS DL or Joint TCI State_v1730).

[0185] It is understandable that the above content describes the configuration of SRS resource related parameters that can be used in the resource configuration process. The following embodiments will specifically describe the time domain, frequency domain, and code domain constraints for the two cases -A) and -B).

[0186] In some embodiments, the 3-antenna port SRS resources determined based on -A) can be divided into at least one of the following -A1) and -A2) based on time domain division:

[0187] -A1) 3 antenna port SRS resources are used to send different SRS resources in the same time slot.

[0188] -A2) 3 antenna port SRS resources are used to send different SRS resources in different time slots.

[0189] Optionally, for -A1), SRS resources of different antenna ports in the 1-antenna-port SRS resource and the 2-antenna-port SRS resource satisfy at least one of -A1-1) to -A1-3):

[0190] -A1-1) SRS resources of different antenna ports have the same time domain position, different cyclic shifts, and the same comb resource (comb).

[0191] -A1-2) SRS resources of different antenna ports have the same time domain position, different cyclic shifts, and the same comb resource offset value (comb offset).

[0192] -A1-3) SRS resources of different antenna ports have the same time domain position, the same comb resource, and different comb resource offset values.

[0193] Optionally, for -A1-1), -A1-2) and -A1-3), the starting symbol, the number of occupied symbols and the repetition coefficient can be used to achieve that the 1-antenna port SRS resources and the 2-antenna port SRS resources occupy the same time domain resources (time domain position).

[0194] Optionally, for -A1-1, different cyclic shifts, the same comb resources, and comb resource offset values ​​can be allocated to different SRS resources through code division multiplexing. Optionally, for -A1-2), different cyclic shifts and the same comb resource offset values ​​can be allocated to different SRS resources through code division multiplexing.

[0195] Optionally, for -A1-3), the same comb resource and different comb resource offset values ​​may be allocated to different SRS resources in a frequency division multiplexing manner.

[0196] Optionally, for -A2), SRS resources of different antenna ports in the 1-antenna-port SRS resource and the 2-antenna-port SRS resource satisfy at least one of -A2-1) to -A2-4):

[0197] -A2-1) SRS resources of different antenna ports have different time domain positions, the same comb resources, the same comb resource offset value, and different cyclic shifts.

[0198] -A2-2) SRS resources of different antenna ports have different time domain positions, the same comb resources, and the same comb resource offset value.

[0199] -A2-3) SRS resources of different antenna ports have different time domain positions, the same comb resources, and different comb resource offset values.

[0200] -A2-4) There is no configuration restriction on frequency domain resources and / or code domain resources for SRS resources of different antenna ports.

[0201] It can be understood that, through the above-mentioned description of the solutions of -A1) and -A2), the constraints of the time domain, frequency domain, and code domain in the case of -A) can be achieved.

[0202] In some embodiments, with respect to -B), a 3-antenna-port SRS resource may be determined based on two 2-antenna-port SRS resources.

[0203] It can be understood that a 3-antenna-port SRS resource is determined based on two 2-antenna-port SRS resources, where one of the 2-antenna ports may have one antenna port that is not used. In order to ensure that the 3-antenna-port SRS resource can be used normally, it is necessary to remove the idle port (i.e., the unused port).

[0204] Based on this, in some embodiments, for -B), the following method is used to determine the 3-antenna port SRS resources:

[0205] Remove the SRS resource of one antenna port from the two 2-antenna-port SRS resources to obtain one 2-antenna-port SRS resource and one 2-antenna-port SRS resource from which the SRS resource is removed;

[0206] The 3-antenna-port SRS resource is determined based on the one 2-antenna-port SRS resource and the one 2-antenna-port SRS resource with the SRS resource removed.

[0207] In some embodiments, the SRS resource of one antenna port in the two 2-antenna-port SRS resources may be removed by at least one of the following methods:

[0208] Based on the default rule, remove the SRS resource of one antenna port from the two 2-antenna-port SRS resources;

[0209] Based on the configuration information of the higher-layer signaling, the SRS resource of one antenna port is removed from the two SRS resources of two antenna ports.

[0210] Based on preset parameters, the SRS resource of one antenna port among the two 2-antenna-port SRS resources is implicitly removed.

[0211] It can be understood that by removing the SRS resource of one antenna port from the two 2-antenna-port SRS resources, the resulting 2-antenna-port SRS resource without the SRS resource is equivalent to a single SRS resource with a single antenna port, which is approximately the same as case -A). Based on case -A), corresponding time domain, frequency domain, and code domain constraints are then applied to obtain SRS resources for three antenna ports.

[0212] It is understandable that -B) can also be applied to SRS resources of other types of ports: for example, when determining an SRS resource for 5 antenna ports using a 2-antenna port SRS resource and a 4-antenna port SRS resource, one antenna port of the 2-antenna port SRS resource can be removed in advance, and then the resource is equivalent to the 5-antenna port SRS resource with the 4-antenna port SRS resource. Alternatively, one antenna port of the 4-antenna port SRS resource can be removed in advance, and then the resource is equivalent to the 5-antenna port SRS resource with the 2-antenna port SRS resource. Specific combinations can be made based on the actual number of antenna ports required for the SRS resource, and will not be detailed here.

[0213] As described above, for removing the SRS resource of one antenna port from the two 2-antenna-port SRS resources, the resulting 2-antenna-port SRS resource with the SRS resource removed is equivalent to one 1-antenna-port SRS resource, which can be approximated as -A). Then -B) also has the following corresponding constraints for the time domain, frequency domain, and code domain.

[0214] In some embodiments, the 3-antenna port SRS resources determined based on -B) can be divided into at least one of the following -B1) and -B2) based on time domain division:

[0215] -B1) 3 antenna port SRS resources are used to send different SRS resources in the same time slot.

[0216] -B2) 3 antenna port SRS resources are used to send different SRS resources in different time slots.
