[0157] 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 .

[0158] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0160] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

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.

[0165] 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 .

[0166] 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).

[0167] 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.

[0168] It is understood that the SRS may be periodic, aperiodic, or semi-persistent. In some embodiments, the SRS may be narrowband or broadband.

[0169] 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.

[0170] In some embodiments, the SRS may support mapping on all orthogonal frequency division multiplex (OFDM) symbols in an uplink timeslot in R17.

[0171] In some embodiments, the configuration of the SRS port may be implemented based on code division multiplexing or frequency division multiplexing.

[0172] 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.

[0173] In some embodiments, the number of SRS resources supported may be configured through high-level parameters.

[0174] Exemplary includes, for example, the number of SRS ports (number of Sounding Reference Signal ports, nrofSRS-Ports).

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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).

[0182] It is understood that, in the case of a non-TDM mapping mode, any of the following cyclic shift configurations may be used:

[0183] Different cyclic shift multiplexing is allocated on the same comb value of 2 (comb-2);

[0184] 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;

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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:

[0189] Among them, the values ​​of n and l′ can be as follows:

[0190] 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 ).

[0191] In some embodiments, for the cyclic shift α i and antenna port p i The relationship is based on the following formula 2:

[0192] 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:

[0193] In addition to the case where the high-level parameter nrofSRS-Ports is ports8tdm, The value of is 1.

[0194] 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.

[0195] Table 1

[0196] Table 1 shows the corresponding relationship between the number of combs (ie, the value of KTC) and the most supportable number of cyclic shifts.

[0197] 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

[0198] In some embodiments, different configured comb numbers support different SRS port capacities, including, for example, when the comb value is 2, the supported SRS port capacity is 16 (2*8=16), and when the comb value is 4, the supported SRS port capacity is 48 (4*12=48).

[0199] 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:

[0200] The range of the cyclic shift number of the SRS can be as follows:

[0201] 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.

[0202] 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}.

[0203] 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.

[0204] 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 determining SRS resources for the number of ports newly supported by the terminal based on the SRS resources corresponding to the number of ports already supported by the terminal.

[0205] In the embodiment of the present disclosure, the number of ports newly supported by the terminal is referred to as the first antenna port number, or 3 antenna ports.

[0206] In one example, the number of first antenna ports is 3.

[0207] In the following embodiments of the present disclosure, configuring SRS resources for antenna ports with a first number of antenna ports is referred to as configuring first SRS resources, which is also referred to as 3-antenna port SRS resources.

[0208] It should be noted that, for ease of description and understanding, in the following embodiments, "first SRS resource" can be understood as "SRS resource of 3 antenna ports", and "first SRS resource" and "SRS resource of 3 antenna ports" can be replaced with each other.

[0209] In some embodiments, the SRS resources for three antenna ports are determined based on other SRS resources different from the first SRS resources. The other SRS resources may be referred to as second SRS resources. The second SRS resources are SRS resources with a second number of antenna ports.

[0210] In one example, the number of the first antenna ports is different from the number of the second antenna ports, and the number of the second antenna ports is any one of the following: 1 port, 2 ports, 4 ports, and 8 ports.

[0211] Exemplarily, the number of the first antenna ports is 3 ports, and the number of the second antenna ports is any one of 1 port, 2 ports, 4 ports, and 8 ports.

[0212] In some embodiments, the SRS resources of three antenna ports are determined based on the SRS resources of a single port (ie, the number of antenna ports is one port).

[0213] In the following embodiments, the “second SRS resource” and the “single-port SRS resource” may be interchangeable.

[0214] 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:

[0215] Step S2101: Terminal 101 determines 3-antenna port SRS resources.

[0216] In some embodiments, the network device 102 configures 3-antenna port SRS resources.

[0217] In some embodiments, 3-antenna port SRS resources are used by terminal 101 to perform codebook-based SRS resource transmission based on the number of 3 antenna ports.

[0218] The terminal 101 performing codebook-based SRS resource transmission based on the first number of antenna ports can be understood as the terminal sending the codebook-based SRS resource to the network device based on the three-antenna port SRS resources.

[0219] In some embodiments, codebook-based SRS resources are used to determine uplink channel state information.

[0220] In some embodiments, a first capability is configured for the terminal 101 based on high-layer signaling, wherein the first capability is a capability of supporting transmission using 3-antenna port SRS resources.

[0221] Optionally, the high-layer signaling includes, for example, signaling related to the number of SRS ports (number of Sounding Reference Signal ports, nrofSRS-Ports).

[0222] In some embodiments, the 3-antenna-port SRS resources for resource transmission by the 3 antenna ports are determined based on the 3 single-port SRS resources. Alternatively, it can be considered that the 3 single-port SRS resources are equivalent to 1 3-antenna-port SRS resource.

[0223] In some embodiments, "SRS resources supporting 1-port resource transmission" and "single-port SRS resources" may be used interchangeably.

[0224] In some embodiments, the 3-antenna port SRS resources are configured based on the 3 single-port SRS resources in at least one of the following ways:

[0225] -A) Perform first parameter configuration on each of the three single-port SRS resources.

[0226] -B) performing a second parameter configuration on the 3-antenna-port SRS resource, where a mapping relationship exists between the second parameter configured for the 3-antenna-port SRS resource and the 3 single-port SRS resources.

[0227] -C) performing a second parameter configuration on the 3-antenna-port SRS resource, where a mapping relationship exists between the second parameter of the 3-antenna-port SRS resource configuration and the 3 single-port SRS resources.

[0228] For example, following the above embodiment, the method A) can be understood as performing corresponding parameter configuration for each of the three single-port SRS resources.

[0229] The -B) method can be understood as directly configuring parameters for the 3-antenna-port SRS resources, where the 3-antenna-port SRS resources are determined by 3 single-port SRS resources.

[0230] Method -C) can be understood as performing parameter configuration for a resource set that includes three single-port SRS resources. For example, if a resource set (the resource set is labeled to indicate that three single-port SRS resources are equivalent to one three-antenna-port SRS resource) includes three single-port SRS resources, parameter configuration is performed for this resource set.

[0231] In some embodiments, the network device configures the SRS resource set as 3 ports, and configures 3 single-port SRS resources in the SRS resource set.

[0232] In some embodiments, the parameters involved in the parameter configuration in the above example include at least one of the following: resource type, power control parameter, frequency hopping sequence parameter, frequency hopping parameter, sequence ID, and spatial relationship.

[0233] 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.

[0234] 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.

[0235] 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).

[0236] Optionally, the frequency hopping sequence parameter includes at least one of the following: group hopping or sequence hopping.

[0237] Optionally, the frequency hopping parameter includes at least one of the following: frequency hopping (freqhopping), frequency domain position (freqDomainPosition), or frequency domain shift (frqeDomainShift).

[0238] 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).

[0239] In some embodiments, each of the three single-port SRS resources has the same parameters, and the same parameters at least include the same resource type or the same spatial relationship.

[0240] In some embodiments, the restrictions on the time domain positions of different single-port SRS resources among the three single-port SRS resources include any one of the following:

[0241] -a) Different single-port SRS resources among the three single-port SRS resources have the same time domain position.

[0242] -b) Different single-port SRS resources among the three single-port SRS resources have different time domain positions.

[0243] In some embodiments, for case -a), configuration implementation can be performed for the following parameters: starting symbol, number of occupied symbols, or repetition coefficient.

[0244] In some embodiments, for case -a), for the second SRS resources of the first number of antenna ports, frequency domain resources and / or code domain resources are configured based on the following manner:

[0245] -a1) For each of the three single-port SRS resources, the same frequency domain resources are configured, and different code domain resources are configured based on a code division multiplexing manner.

[0246] -a2) For each of the three single-port SRS resources, the same or different code domain resources are configured, and different frequency domain resources are configured based on a frequency division multiplexing manner.

[0247] -a3) For each of the three single-port SRS resources, frequency domain resources and / or code domain resources are configured based on code division multiplexing and frequency division multiplexing.

[0248] In some embodiments, for method -a1), each of the three single-port SRS resources is configured with the same comb resource (comb), time domain resource (such as the number of symbols), comb resource offset value (comb offset), and different cyclic shift (cs).

[0249] Optionally, the cyclic shift can be configured in any of the following ways:

[0250] 1) Based on the initial cyclic shift and the first condition configuration, wherein the initial cyclic shift is the cyclic shift corresponding to the first single-port SRS resource determined by the single-port SRS resource index, the first condition is that the cyclic shifts corresponding to other SRS resources meet the same interval, and the other SRS resources are the single-port SRS resources other than the first single-port SRS resource among the three single-port SRS resources.

[0251] 2) Based on the initial cyclic shift and the second condition configuration, wherein the initial cyclic shift is the cyclic shift corresponding to the first single-port SRS resource determined by the single-port SRS resource index, the second condition is that the cyclic shifts corresponding to other SRS resources satisfy a uniform distribution, and the other SRS resources are the single-port SRS resources among the three single-port SRS resources except the first single-port SRS resource.

[0252] 3) Perform random configuration cyclic shift on each single-port SRS resource.

[0253] For example, for method 1), it can be understood that the same cyclic shift interval is used for different single-port SRS resources. For example, when the comb value is 8 and the corresponding cyclic shift interval is 1, if the first cyclic shift value determined based on the single-port SRS resource index order is 0 (i.e., cs1=0), then the second cyclic shift value is 1 (i.e., cs2=1), and the third cyclic shift value is 2 (i.e., cs3=2).

[0254] For example, with respect to method 2), it can be understood that the cyclic shifts for each single-port SRS resource configuration are uniformly distributed starting from the first cyclic shift according to the order of the single-port SRS resource index. For example, if the value of comb is 8, then if the first cyclic shift value determined based on the single-port SRS resource index order is 0 (i.e., cs1=0), then the second cyclic shift value is 1 (i.e., cs2=2), then the third cyclic shift value is 4 (i.e., cs3=4).

[0255] For example, with respect to method 3), it can be understood as other configuration methods that do not follow method 1) and / or method 2).

[0256] In some embodiments, for the -a2) method, the method includes configuring the same comb and time domain resources (such as the number of symbols) and different comb offsets for each second SRS resource of the first number of antenna ports.

[0257] Optionally, the value of comb includes 4 or 8.

[0258] In some embodiments, the comb offset is configured in any of the following ways:

[0259] -1) Configure comb offset continuous allocation.

[0260] -2) Configure the maximum comb offset distance.

[0261] -3) Evenly configure comb offset.

[0262] -4) Randomly configure comb offset.

[0263] Exemplarily, method -1) can be understood as configuring the comb offset value based on two adjacent second SRS resources respectively. For example, there are three single-port SRS resources, namely: a single-port SRS resource identified as #1, a single-port SRS resource identified as #2, and a single-port SRS resource identified as #3. The index order of the single-port SRS resources is: #1, #2, and #3. Then method -1) can be understood as configuring the comb offset value between the single-port SRS resource #1 and the single-port SRS resource #2, and configuring the comb offset value between the single-port SRS resource #2 and the single-port SRS resource #3. Here, for example, if the comb value corresponding to the single-port SRS resource #1 is 0, then the comb offsets corresponding to the three SRS resources are allocated to be 0, 1, and 2 respectively.

[0264] Exemplarily, method -2) can be understood as configuring the comb offset value for two adjacent single-port SRS resources to maximize the comb offset. For example, following the embodiment of method -1), the comb value is 8, the comb value corresponding to the single-port SRS resource #1 is 0, and the comb offset value between the single-port SRS resource #1 and the single-port SRS resource #2 is required to be the largest (i.e., greater than the comb offset value between the single-port SRS resource #2 and the single-port SRS resource #3). In this case, the comb offset value between the single-port SRS resource #1 and the single-port SRS resource #2 can be configured to 5. The corresponding comb values ​​for the three are: 0, 4, and 7, respectively.

[0265] For example, approach 3) can be understood as uniformly configuring the comb offset values ​​corresponding to all three single-port SRS resources. Continuing with approach 1), the comb value is 8, the comb value corresponding to single-port SRS resource #1 is 0, and the comb offset values ​​between the second SRS resource #1, the single-port SRS resource #2, and the single-port SRS resource #3 are required to be uniformly configured. Then, the corresponding comb values ​​for the three can be: 0, 3, and 6, respectively.

[0266] Exemplarily, mode-4) may be understood as other comb offset configuration modes in addition to mode-1), mode-2) and mode-3).

[0267] In some embodiments, the method -a3) includes any one of the following:

[0268] -1) Configuring the same designated parameters for a first number of single-port SRS resources, and configuring designated parameters for a second number of second SRS resources.

[0269] -2) Different designated parameters are configured for the three single-port SRS resources.

[0270] Optionally, the designated parameters include: a comb resource offset value, the value of the designated parameter corresponding to the first number of single-port SRS resources is different from the value of the third parameter and the value of the designated parameter corresponding to the second number of second SRS resources, and the sum of the first number and the second number is the first antenna port number.

[0271] For example, the first number is 2 and the second number is . For method 1), it can be understood that: the same comb resource offset value is configured for two of the three single-port SRS resources, and the comb resource offset value is configured for the remaining single-port SRS resource, but the two values ​​are different. For method 2), it can also be understood that all three single-port SRS resources are configured with comb offset values ​​that are different from each other.

[0272] Optionally, for each of the three single-port SRS resources, frequency domain resources and / or code domain resources are configured based on code division multiplexing and frequency division multiplexing, including: configuring the same first comb resource offset value for two of the three single-port SRS resources, and configuring a second comb resource offset value for one of the three single-port SRS resources, the first comb resource offset value and the second comb resource offset value being different; or configuring different comb resource offset values ​​for the three single-port SRS resources.

[0273] In summary, it is possible to implement constraints on corresponding parameters for each single-port SRS resource configuration in the code domain and the frequency domain when the single-port SRS resources are in the same time domain position.

[0274] In some embodiments, for case -b), at least one of the following is satisfied:

[0275] Different single-port SRS resource configurations have the same comb resource, the same number of symbols, the same comb resource offset value, the same cyclic offset value or different cyclic offset values;

[0276] Different single-port SRS resource configurations have the same comb resources and number of symbols, the same comb resource offset value or different comb resource offset values.

[0277] Optionally, the comb configuration value includes: 4 or 8.

[0278] Optionally, different single-port SRS resources among the three single-port SRS resources have different time domain positions and have the same comb resource and / or have no restrictions on comb resource offset values ​​and cyclic offset values.

[0279] In some embodiments, in case -b), each symbol is configured with an independent second SRS resource, without configuration restriction.

[0280] In summary, it is possible to implement constraints on corresponding parameters for each single-port SRS resource configuration from the code domain and the frequency domain when each single-port SRS resource is at a different time domain position.

[0281] In some embodiments, there is a mapping relationship between the antenna port corresponding to each single-port SRS resource and each antenna port corresponding to the 3-antenna-port SRS resource.

[0282] In some embodiments, the 3-antenna port SRS resource may also be obtained by expanding one single-port SRS resource, where the one single-port SRS resource is configured by the network device 102 .

[0283] Exemplarily, the network device configures 3 ports to an SRS resource or resource set, and then the resource set actually configures a single-port SRS resource, and then the terminal generates and sends a 3-port SRS resource by expanding a single port into a 3-port SRS.

[0284] For example, following the above embodiment, one single-port SRS resource configured by the network device 102 is expanded to three single-port SRS resources, and then one three-antenna-port SRS resource is determined based on the three single-port SRS resources.

[0285] In some embodiments, for resources pre-configured based on the network device 102, one single-port SRS resource is extended, including at least one of the following: based on the first step length, one single-port SRS resource is extended in the frequency domain; based on the single-port SRS resource, a time domain extension is performed by repeatedly processing continuous time domain resources; based on the continuously allocated cyclic shift or the cyclic shift allocated by the second step length, one single-port SRS resource is extended in the code domain.

[0286] For example, the network device configures 3 ports for an SRS resource or an SRS resource set, and then actually configures a single-port SRS resource for the 3-port configured SRS resource or SRS resource set. The terminal expands the single-port SRS resource into a 3-port SRS resource.

[0287] In some embodiments, there is a mapping relationship between the antenna port corresponding to each single-port SRS resource and each antenna port corresponding to the 3-antenna-port SRS resource.

[0291] In step S2102 , the terminal 101 sends codebook-based SRS resources to the network device 102 based on the 3-antenna port SRS resources.

[0292] In some embodiments, the terminal sends a codebook-based SRS resource to a network device, and the network device receives the codebook-based SRS resource, demodulates the codebook-based SRS resource, and obtains uplink channel state information, such as RANK value, CQI, TPMI, etc.
