[0148] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0149] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than those in FIG. 1. The number and form of each subject is arbitrary, and the connection relationship between the subjects is exemplary. The subjects can not be connected or can be connected, and the connection can be in any manner, can be direct connection or indirect connection, and can be wired connection or wireless connection.

[0150] 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 (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0151] In the related standards, the frequency hopping design of PRS and SRS positioning reference signals is introduced for reduced capability (RedCap) terminals to enhance the positioning bandwidth and improve the positioning accuracy. Since the random phase between two hops cannot be kept consistent when SRS frequency hopping occurs, phase offset estimation needs to be performed through the overlapping RBs between the two hops. However, when the number of overlapping RBs is too large, it will affect the total positioning bandwidth and the positioning accuracy. Therefore, for the estimation of overlapping RBs, a reasonable value needs to be selected between the evaluation accuracy of the phase offset and the actual total bandwidth of the positioning signal. Finally, the protocol sets the overlapping RBs to {0, 1, 2, 4}.

[0152] For the case where the value is "0", some companies propose that the performance gain provided by the overlapping RBs only exists when the phase offset is large. When the phase offset is small, the performance improvement of the overlapping RBs can be ignored. The phase offset may be related to the stability of the terminal radio frequency (RF). Therefore, the terminal can first report the capability related to the phase offset when reporting the UE capability. The gNB / LMF can determine the value of the overlapping RBs based on the UE capability report, for example, the value can be 0.

[0153] Therefore, in the frequency hopping of PRS / SRS positioning reference signals for reduced capability terminals (RECAP PRS / SRS frequency hopping), the terminal first performs UE capability reporting related to the overlapping RBs. The gNB / LMF configures the actual overlapping RBs for the UE based on the reporting parameter.

[0154] Optionally, the above-mentioned frequency hopping mechanism of the positioning reference signals (R18 REDCAP PRS / SRS positioning frequency hopping) can be introduced for use by enhanced mobile broadband (eMBB) terminals that do not support uplink intra-band carrier aggregation (intra-band CA). After the introduction of this mechanism, the positioning accuracy of eMBB UEs that do not support intra-band CA can be enhanced, and the eMBB terminal can perform SRS / PRS frequency hopping between different component carriers (CCs) of the intra-band CA to enhance its transmission bandwidth.

[0155] For the eMBB UE to hop between intra-band CCs, one issue to be considered is how to determine the bandwidth occupied by each hop to avoid data transmission on the guard band as much as possible and avoid inter-band interference to data transmission of other terminals.

[0156] To solve the above problem, the present disclosure provides a communication method which can determine the frequency domain position of a terminal not supporting intra-band carrier aggregation when performing frequency hopping transmission. The specific content of the method is as follows.

[0157] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the present embodiment relates to a communication method for a communication system 100 which can include a terminal 101 and a network device 102, and the above method includes:

[0158] In step 2101, the terminal sends second information to the network device.

[0159] In some embodiments, the terminal can send the second information to the network device, wherein the second information is used to indicate at least one of the following capabilities:

[0160] whether the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a frequency hopping manner based on the first information; whether the terminal supports the value of the overlapping resource block between every two frequency domain resources being negative; whether the terminal supports the value of the frequency domain offset corresponding to each frequency domain resource being positive, and / or the value of the frequency domain offset being greater than or equal to the value of the guard band; the value of the frequency domain offset corresponding to each frequency domain resource supported by the terminal; the value of the overlapping frequency domain resource between every two frequency domain resources supported by the terminal, which can be negative; whether the terminal supports transmitting the first reference signal and / or receiving the second reference signal in an intra-band CA frequency hopping manner; whether the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a first intra-band CA frequency hopping manner; when the value of the second information is empty, by default, the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a second intra-band CA frequency hopping manner; whether the terminal supports transmitting the first reference signal and / or receiving the second reference signal in the first and / or second intra-band CA frequency hopping manner.

[0161] In other words, the terminal can report the terminal capability, for example, the terminal can report whether the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a frequency hopping manner based on the first information, the network device can receive the terminal reported capability, and configure relevant parameters for the terminal according to the terminal reported capability information, for example, the network device can configure the frequency hopping time, the bandwidth and the frequency domain location of each hop and the like for the terminal when the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a frequency hopping manner based on the first information.

[0162] In some embodiments, the terminal is a terminal that does not support intra-band carrier aggregation, where the intra-band carrier aggregation is continuous intra-band carrier aggregation.

[0163] In other words, the terminal can be a terminal that does not support continuous intra-band carrier aggregation, at this time, by determining the frequency domain location of each hop when the terminal frequency hops, the frequency hopping mechanism can be introduced for the terminal that does not support continuous intra-band carrier aggregation, and when the reference signal transmission is performed by using the frequency hopping mechanism, the interference of the transmitted signal during transmission can be reduced, and the accuracy during positioning based on the reference signal can be improved.

[0164] Step 2102a, the terminal determines the first information.

[0165] In some embodiments, the first information is used to indicate the frequency domain resource for transmitting the first reference signal and / or receiving the second reference signal in a frequency hopping manner.

[0166] In some embodiments, after the terminal determines the first information, the terminal can transmit the first reference signal and / or receive the second reference signal in a frequency hopping manner according to the indication of the first information, in other words, the first information can be used to determine the corresponding frequency domain resource when frequency hopping is used, that is, the first information can indicate the relevant parameters when the terminal transmits the first reference signal and / or receives the second reference signal in a frequency hopping manner, for example, the first information can indicate the frequency domain location and the bandwidth of each hop and the like.

[0167] In some embodiments, optionally, the first reference signal can be an uplink reference signal, for example, it can be a sounding reference signal SRS, the sounding reference signal SRS can be used for uplink positioning, when the first reference signal is the sounding reference signal SRS, the terminal can transmit the first reference signal to the network device.

[0168] In some embodiments, optionally, the second reference signal can be a downlink reference signal, for example, it can be a positioning reference signal PRS, the positioning reference signal PRS can be used for downlink positioning, when the second reference signal is the positioning reference signal PRS, the network device can transmit the second reference signal to the terminal.

[0169] In some embodiments, the terminal can determine the first information based on an indication of the network device or a protocol agreement, wherein the first information comprises a frequency domain offset corresponding to each frequency hopping domain resource when transmitting the first reference signal and / or receiving the second reference signal between the multiple carrier units in the first frequency band.

[0170] In other words, the terminal can transmit the first reference signal and / or receive the second reference signal between the multiple carrier units in the first frequency band, i.e., the terminal can transmit the first reference signal and / or receive the second reference signal in the first frequency band in a frequency hopping manner. Optionally, the terminal can receive the first information indicated by the network device or can determine the first information according to a protocol agreement. At this time, the first information can be a frequency domain offset corresponding to each frequency hopping domain resource. For example, the frequency domain offset corresponding to each frequency hopping domain resource can be a frequency domain offset value of the N+1th hop relative to the Nth hop, i.e., a frequency domain offset value between two hops, or a frequency domain offset value of the N+1th hop relative to a reference point, i.e., a frequency domain offset value of each hop relative to a reference point, etc. Optionally, the method of determining the first information according to the indication of the network device or the protocol agreement can be any of the following.

[0171] First method (Direction 1)

[0172] Method 1

[0173] In some embodiments, determining the first information comprises determining a frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource based on first indication information of the network device, wherein the first indication information is used to indicate a value of an overlapping resource block between the Nth frequency domain resource and the N+1th frequency domain resource, the value of the overlapping resource block is a negative number, and N is a positive integer.

[0174] In some embodiments, the network device can indicate the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource through the first indication information, wherein the value of the overlapping resource block can be the number of overlapping resource blocks, i.e., the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource can be an integer multiple of the bandwidth of the overlapping resource block.

[0175] In other words, the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource can be configured to determine the frequency domain offset between the two hops, thereby determining the first information. At this time, the frequency domain offset corresponding to the two frequency domain resources can be a frequency domain offset value of the N+1th hop relative to the Nth hop.

[0176] Optionally, the number of overlapping resource blocks can be configured as a negative number, in which case the Nth frequency domain resource and the N+1th frequency domain resource do not overlap, and there is an interval between the Nth frequency domain resource and the N+1th frequency domain resource, i.e., there is a frequency domain offset amount, wherein the frequency domain offset amount is an integer multiple of the bandwidth of the overlapping resource blocks. For example, when the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource is -2, the frequency domain offset amount between the Nth frequency domain resource and the N+1th frequency domain resource is the length of two resource blocks.

[0177] In some embodiments, for example, the frequency domain offset amount between the Nth frequency domain resource and the N+1th frequency domain resource needs to be greater than or equal to the bandwidth length of the guard band, which can avoid transmitting a reference signal on the guard band. Specifically, the value of the overlapping resource blocks can be determined according to the length of the guard band, wherein the bandwidth of the guard band can be determined according to Table 1 below.

[0178] Table 1

[0179] In some embodiments, the value of the guard band in the above table can be determined according to the maximum value of the bandwidth of the lowest frequency point and the bandwidth of the highest frequency point in the following table; or the value of the guard band can be determined according to the maximum value of all bandwidths and the current subcarrier spacing.

[0180] In some embodiments, the bandwidth occupied by the overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource is greater than or equal to the bandwidth occupied by the guard band between the Nth frequency domain resource and the N+1th frequency domain resource.

[0181] In other words, the frequency domain offset amount between the Nth frequency domain resource and the N+1th frequency domain resource needs to satisfy both conditions of being greater than the guard band width and being an integer multiple of the bandwidth of the overlapping resource blocks, i.e., the frequency domain offset amount between the Nth frequency domain resource and the N+1th frequency domain resource can be an integer number of overlapping resource blocks that is greater than and closest to the guard band bandwidth, i.e., the guard band bandwidth can be determined first, and then the number of overlapping resource blocks can be determined according to the bandwidth of the overlapping resource blocks. For example, when the bandwidth of 3 overlapping resource blocks is less than the bandwidth of the guard band, but the bandwidth of 4 overlapping resource blocks is greater than the bandwidth of the guard band, the value of the overlapping resource blocks can be determined as -4.

[0182] Method 2

[0183] In some embodiments, determining the first information includes determining a frequency domain offset amount between the Nth frequency domain resource and the N+1th frequency domain resource based on a guard band between the Nth frequency domain resource and the N+1th frequency domain resource.

[0184] In some embodiments, determining the first information comprises: determining a frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource based on second indication information of the network device, wherein the second indication information is used to indicate a value of a guard band between the Nth frequency domain resource and the N+1th frequency domain resource.

[0185] In other words, the terminal can determine the frequency domain offset according to the value of the guard band between the Nth frequency domain resource and the N+1th frequency domain resource. For example, the value of the guard band between the Nth frequency domain resource and the N+1th frequency domain resource can be indicated by the network device or can be predefined by a protocol, and the disclosure does not limit this.

[0186] Specifically, the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource can be directly determined according to the guard band between the Nth frequency domain resource and the N+1th frequency domain resource. At this time, the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource can not be an integer number of overlapping resource blocks. At this time, the frequency domain offset corresponding to the two frequency domain resources can be a frequency domain offset value of the N+1th frequency domain resource relative to the Nth frequency domain resource.

[0187] In some embodiments, the bandwidth occupied by the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource is greater than or equal to the bandwidth occupied by the guard band between the Nth frequency domain resource and the N+1th frequency domain resource. Alternatively, the number of resource blocks RB included in the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource is greater than or equal to the number of RBs included in the guard band between the Nth frequency domain resource and the N+1th frequency domain resource. Alternatively, the number of RBs included in the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource is greater than or equal to the number of RBs included in the maximum guard band.

[0188] In other words, the frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource can be determined according to the bandwidth of the guard band, for example, the frequency domain offset can be determined to be greater than or equal to the bandwidth of the guard band; or, the number of overlapping resource blocks closest to and greater than the bandwidth of the guard band can be determined according to the guard band determined by the above method 1 according to the above table 1, and the frequency domain offset can be determined according to the number of overlapping resource blocks, for example, when the number of overlapping resource blocks contained by the guard band is greater than 3 and less than 4, the number of overlapping resource blocks closest to and greater than the bandwidth of the guard band can be determined to be 4, and the frequency domain offset can be the bandwidth of 4 overlapping resource blocks at this time; or, the frequency domain offset can also be determined to be the bandwidth of an integer number of overlapping resource blocks, but at this time the number of overlapping resource blocks can be greater than the number of overlapping resource blocks contained by the maximum guard band, for example, the value of the maximum guard band can be determined according to the above table 1, and the value of the maximum guard band can be determined to be the bandwidth of how many overlapping resource blocks, and the frequency domain offset can be determined according to the number of overlapping resource blocks contained by the guard band, for example, when the number of overlapping resource blocks contained by the maximum guard band is greater than 5 and less than 6, the number of overlapping resource blocks closest to and greater than the bandwidth of the guard band can be determined to be 6, and the frequency domain offset can be the bandwidth of 6 overlapping resource blocks at this time.

[0189] Method 3

[0190] In some embodiments, determining the first information comprises: determining a frequency domain offset corresponding to each frequency hopping domain resource based on a common frequency domain reference point corresponding to the first frequency band and a starting point corresponding to each frequency hopping domain resource.

[0191] In some embodiments, the frequency domain offset corresponding to each frequency hopping domain resource is an offset of the starting point corresponding to each frequency hopping domain resource relative to the common frequency domain reference point; and wherein, in each two frequency hopping domain resources, a sum of a starting point corresponding to an Nth frequency hopping domain resource and a bandwidth of the Nth frequency hopping domain resource is less than or equal to a starting point corresponding to an N+1th frequency hopping domain resource.

[0192] In other words, a common frequency domain reference point can be set for the first frequency band, and a corresponding starting point can be configured for each frequency hopping domain resource, at this time the frequency domain offset of each frequency hopping is the offset of the starting point to the common frequency domain reference point. Optionally, the corresponding starting point of each frequency hopping domain resource can be configured according to the number of overlapping resource blocks, specifically, the starting point of the Nth frequency hopping domain resource can be determined according to the starting point of the N-1th frequency hopping, the bandwidth of the N-1th frequency hopping, and the number of overlapping resource blocks, for example, the number of overlapping resource blocks can be determined to be 2, the end point of the N-1th frequency hopping domain resource can be determined according to the starting point of the N-1th frequency hopping and the bandwidth of the N-1th frequency hopping, and the frequency domain resource position obtained by adding the bandwidth of 2 overlapping resource blocks to the end point can be determined as the starting point of the Nth frequency hopping domain resource.

[0193] In the above embodiment, the sum of the starting point corresponding to the Nth frequency hopping domain resource and the bandwidth of the Nth frequency hopping domain resource is less than or equal to the starting point corresponding to the (N+1)th frequency hopping domain resource, that is, there is no overlapping part between the two frequency hopping domain resources.

[0194] In the above embodiment, the common frequency domain reference point can be predefined by a protocol, or can be configured for the terminal by a network device through a system message or a broadcast message, or can be configured for the terminal by the network device through Radio Resource Control (RRC) signaling, and the disclosure does not limit this.

[0195] Method 4

[0196] In some embodiments, determining the first information includes: determining a frequency domain offset corresponding to each frequency hopping domain resource based on the reference point corresponding to each frequency hopping domain resource in the first frequency band and the starting point corresponding to each frequency hopping domain resource.

[0197] In some embodiments, the frequency domain offset corresponding to each frequency hopping domain resource is an offset between the starting point corresponding to each frequency hopping domain resource and the reference point corresponding to each frequency hopping domain resource.

[0198] In other words, different reference points and starting points can be configured for each hop, and at this time the frequency domain offset of each hop is the offset between the reference point of each hop and the starting point of each hop. As described above in method 3, the starting point corresponding to each frequency hopping domain resource can be configured according to the number of overlapping resource blocks; and the sum of the starting point corresponding to the Nth frequency hopping domain resource and the bandwidth of the Nth frequency hopping domain resource is less than or equal to the starting point corresponding to the (N+1)th frequency hopping domain resource, that is, there is no overlapping part between the two frequency hopping domain resources, which will not be repeated here.

[0199] In the above embodiment, the reference point of each hop can be predefined by a protocol, or can be configured for the terminal by a network device through a system message or a broadcast message, or can be configured for the terminal by the network device through RRC signaling, and the disclosure does not limit this.

[0200] Second way (Direction 2)

[0201] Method 5

[0202] In some embodiments, the method further includes: determining the first information based on an indication of the network device or a protocol agreement, wherein the first information includes: when the first reference signal is transmitted and / or the second reference signal is received between the multiple carrier units in the first frequency band, the first frequency domain part included in at least one frequency hopping domain resource, and the first frequency domain part is not transmitted with the first reference signal and / or not received with the second reference signal.

[0203] In some embodiments, there are overlapping resource blocks between every two frequency hopping resources, and the number of overlapping resource blocks is zero or positive.

[0204] In other words, the first information can indicate a first frequency domain part on which the first reference signal is not transmitted and / or the second reference signal is not received, i.e., the first frequency domain part can be greater than or equal to the bandwidth of the guard band, which can avoid transmitting the reference signal on the guard band.

[0205] For example, there can be overlapping resource blocks between every two frequency hopping resources of the method, e.g., the Nth frequency hopping resource includes resource block 1, resource block 2, and resource block 3, and the N+1th frequency hopping resource includes resource block 3, resource block 4, and resource block 5, so there is one overlapping resource block between the Nth frequency hopping resource and the N+1th frequency hopping resource. Optionally, at least one frequency hopping resource includes a first frequency domain part on which the first reference signal is not transmitted and / or the second reference signal is not received, i.e., the transmission or reception of the reference signal in one frequency hopping resource of the method can be discontinuous. For example, in the above example, the N+1th frequency hopping resource can include the first frequency domain part, i.e., when the transmission or reception of the reference signal is performed in the N+1th frequency hopping resource, the transmission or reception of the reference signal is performed on resources other than the first frequency domain part, and no transmission or reception of the reference signal is performed in the first frequency domain part.

[0206] In the above embodiments, the first frequency domain part can be determined according to the indication of the network device or the protocol agreement, and the first frequency domain part satisfies at least one of the following: the number of RBs included in the first frequency domain part is 0, a positive integer, or a non-integer; the position of the first frequency domain part is configured by the network device or agreed by the protocol; the position of the first frequency domain part is determined according to the starting position of the Nth frequency hopping resource, and the overlapping resource blocks between every two frequency hopping resources; the position of the first frequency domain part is determined according to the common reference point of the first frequency band and the offset value of the first frequency domain part relative to the common reference point; and the position of the first frequency domain part is determined according to the starting position or the ending position of the current frequency hopping resource and the offset value of the first frequency domain part relative to the starting position or the ending position.

[0207] In some embodiments, optionally, the bandwidth of each frequency hopping resource is the same, and for example, the bandwidth of each frequency hopping resource can or can not include the first frequency domain part. For example, the Nth frequency hopping resource does not include the first frequency domain part, and the bandwidth of the Nth frequency hopping resource is 20 MHz, and the N+1th frequency hopping resource includes the first frequency domain part, i.e., the resource bandwidth on which the reference signal is transmitted and / or received in the N+1th frequency hopping resource plus the bandwidth of the first frequency domain part can be equal to 20 MHz, or the resource bandwidth on which the reference signal is transmitted and / or received in the N+1th frequency hopping resource is 20 MHz.

[0208] In some embodiments, when the terminal reports that the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a frequency hopping manner based on the first information, but does not report support for the frequency domain offset mechanism, the first information can be determined using the above-described method 5, and the first reference signal can be transmitted and / or the second reference signal can be received in a frequency hopping manner based on the first information. When the terminal reports support for the frequency domain offset mechanism, the first information can be determined according to any one of the above-described methods 1-5, and the first reference signal can be transmitted and / or the second reference signal can be received in a frequency hopping manner based on the first information.

[0209] Alternatively, the terminal can directly report whether the terminal supports the value of the overlapping resource block between every two frequency domain resources as negative, when the terminal supports the value of the overlapping resource block between every two frequency domain resources as negative, the terminal can determine the first information by using the method of the above method 1, and transmit the first reference signal and / or receive the second reference signal in a frequency hopping manner based on the first information; or the terminal can report whether the terminal supports the value of the frequency domain offset corresponding to each frequency domain resource as positive, and / or the value of the frequency domain offset is greater than or equal to the value of the guard band, and when the terminal supports this capability, the network device can configure the terminal with the corresponding frequency domain offset according to the capability of the terminal, and the terminal can determine the first information according to the frequency domain offset configured by the network device, and transmit the first reference signal and / or receive the second reference signal in a frequency hopping manner based on the first information; or the terminal can report the value of the frequency domain offset supported by the terminal corresponding to every two frequency domain resources, at this time the network device can configure the terminal with the frequency domain offset according to the value of the frequency domain offset supported by the terminal; or the terminal can report the value of the overlapping frequency domain resource between every two frequency domain resources supported by the terminal, which can be negative, at this time the network device can configure the terminal with the value of the overlapping frequency domain resource according to the value of the overlapping frequency domain resource between every two frequency domain resources supported by the terminal; or the terminal can report that the terminal supports transmitting the first reference signal and / or receiving the second reference signal in an intra-band CA frequency hopping manner, at this time the network device can configure the terminal with the corresponding frequency hopping parameter according to the capability of the terminal, so that the terminal transmits the first reference signal and / or receives the second reference signal in a frequency hopping manner based on the frequency hopping parameter; or the terminal can report that the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a first manner of intra-band CA frequency hopping, wherein when the value of the second information is empty, it is defaulted that the terminal supports transmitting the first reference signal and / or receiving the second reference signal in a second manner of intra-band CA frequency hopping, that is, the second information can indicate that the terminal supports the method in the first manner or supports the method in the second manner; or the terminal can report that the terminal supports transmitting the first reference signal and / or receiving the second reference signal in the first manner and / or the second manner of intra-band CA frequency hopping, that is, the terminal can report that the terminal supports the method in the first manner and the method in the second manner at the same time.

[0210] It should be understood that the "first mode" described in the present disclosure refers to allowing a certain frequency domain offset value between each two hops when the SRS / PRS frequency hopping is performed between multiple CCs in the same band for an eMBB terminal that does not support intra-band CA. The "second mode" described in the present disclosure refers to reusing the value of the overlapping RB in the REDCAP UE SRS / PRS frequency hopping when the SRS / PRS frequency hopping is performed between multiple CCs in the same band for an eMBB terminal that does not support intra-band CA, and the transmission of the SRS or the PRS on at least one hop in all hops can have discontinuous frequency domain resource allocation.

[0211] At step 2102b, the network device determines the first information.

[0212] In some embodiments, the network device and the terminal can each determine the first information according to a protocol agreement, or the network device can determine the first information according to a communication requirement and configure the terminal.

[0213] Optionally, the network device can configure the first information for the terminal according to the capability of the terminal. For example, when the terminal reports its capability as supporting the first reference signal transmission and / or the second reference signal reception in the intra-band CA frequency hopping manner, and the terminal supports discontinuous transmission or reception of the reference signal on at least one frequency domain resource (second mode), the network device can configure the value of the first frequency domain part on the frequency domain resource for the terminal, and the terminal does not transmit the first reference signal and / or receive the second reference signal on the first frequency domain part.

[0214] Optionally, the network device can refer to the capability of the terminal and configure the first information for the terminal according to a specific communication condition. For example, the terminal supports the first mode and / or the second mode, and the network device can configure the terminal to perform SRS / PRS frequency hopping in the first mode.

[0215] For example, the network device can configure the frequency hopping related parameters such as the number of overlapping resource blocks, the starting position of the Nth frequency domain resource, the bandwidth of each hop, and the like for the terminal through RRC signaling.

[0216] In some embodiments, the network device can determine the first information based on a protocol agreement, or configure the first information for the terminal, wherein the first information includes a frequency domain offset corresponding to each frequency hopping frequency domain resource when the first reference signal is transmitted and / or the second reference signal is received between multiple carrier units in the first frequency band.

[0217] In some embodiments, determining the first information comprises determining a frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource based on the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource, wherein the number of overlapping resource blocks is a negative number.

[0218] In some embodiments, the method further comprises configuring the terminal with the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource, wherein the first information is a frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource, and the frequency domain offset is determined based on the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource.

[0219] In other words, the network device can determine the first information according to the protocol, and configure the terminal with the first information, or the network device can configure the terminal with parameters related to the first information, for example, the network device can determine the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource, and configure the terminal with the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource, and the terminal can determine the frequency domain offset between the Nth frequency domain resource and the N+1th frequency domain resource based on the number of overlapping resource blocks between the Nth frequency domain resource and the N+1th frequency domain resource, i.e., the terminal can determine the first information according to the parameters configured by the network device.

[0220] In some embodiments, the network device determines the first information in the same way as the terminal, for example, refer to the methods 1 to 5 in step 2102a, the network device can configure the terminal with the related parameters according to any of the above methods, so that the terminal determines the first information, or the network device can determine the first information according to the related parameters, and the like, which will not be described here.

[0221] In step 2103, the terminal transmits a first reference signal to the network device in a frequency hopping manner based on the first information.

[0222] In some embodiments, the terminal and the network device can determine the frequency domain position for transmitting or receiving the reference signal based on the first information, and the terminal and / or the network device can receive and / or transmit the reference signal in a frequency hopping manner at the frequency domain position indicated by the first information.

[0223] In some embodiments, the reference signal can be the first reference signal, when the reference signal is the first reference signal, for example, the reference signal is a sounding reference signal SRS, the sounding reference signal SRS is used for uplink positioning, and the terminal can transmit the first reference signal to the network device in a frequency hopping manner.

[0224] In some embodiments, this step is optional when the reference signal is the second reference signal, and the terminal can receive the second reference signal in a frequency hopping manner, and this step is optional at this time.

[0225] At step 2104, the network device transmits the second reference signal to the terminal in a frequency hopping manner based on the first information.

[0226] In some embodiments, the terminal and the network device can determine the frequency domain position of transmitting or receiving the reference signal according to the first information, and the terminal and / or the network device can receive and / or transmit the reference signal in the frequency domain position indicated by the first information in a frequency hopping manner.

[0227] In some embodiments, the reference signal can be the second reference signal, and when the reference signal is the second reference signal, for example, the reference signal is a positioning reference signal PRS, the positioning reference signal PRS is used for downlink positioning, and the network device can transmit the second reference signal to the terminal in a frequency hopping manner.

[0228] In some embodiments, this step is optional when the reference signal is the first reference signal, and the network device can receive the first reference signal in a frequency hopping manner, and this step is optional at this time.

[0270] The following is an exemplary introduction to the above method.

[0271] The method according to the embodiments of the present disclosure proposes a determination method for an eMBB UE not supporting intra-band CA to hop within the aggregated bandwidth occupied by intra-band CA, so as to avoid data transmission on the guard band and avoid inter-band interference. The complete content of the method is as follows.

[0272] Solution one: for an eMBB terminal not supporting intra-band CA, when hopping SRS / PRS between multiple carrier units of the same band, a certain frequency offset is allowed between every two hops. A possible example is that the time-frequency domain resources occupied by two hops are as shown in FIG. 6.

[0273] Point 1: to realize the SRS / PRS hopping mode as shown in FIG. 6, at least one of the following modes is considered:

[0274] Option 1: Configuration of resource block offset (RB offset) between two hops via overlapping RB. For example, the value of overlapping RB can be negative, and one possible value in FR1 band is shown in the following table (each value is a candidate value).

[0275] Optionally, the value of overlapping RB can be an integer number of RBs greater than and closest to the value under each configuration in Table 1 above. In the following table, the value of the guard band is determined according to the maximum value of the bandwidth of the lowest frequency point and the bandwidth of the highest frequency point, or the value of the guard band is determined according to the maximum value of the total bandwidth and the current subcarrier spacing.

[0276] Option 2: Configuration of frequency domain offset (FDO), which is the frequency domain offset value of the N+1th hop relative to the Nth hop.

[0277] Regarding the value of the frequency domain offset, one possible way is that the value of the frequency domain offset is shown in Table 1.

[0278] Alternatively, the FDO is an integer number of RBs greater than and closest to the value under each configuration in the above table, or the RB value is 0, i.e. the value of the FDO is 0 RB, i.e. the value of the FDO is 0, or the value of the FDO can be the value of the FDO preset in the protocol, and at this time, the value of the FDO is greater than or equal to the maximum value in the above table (optionally, it can be an integer number of RBs).

[0279] Option 3: Define a common reference point in the frequency domain for each band, and configure the starting point of each hop by gNB / LMF. Optionally, the offset value of the starting point of each hop relative to the common reference point can be configured, and the starting point of each hop can be determined according to the offset value.

[0280] Among them, the following relationship is satisfied between two hops: the starting point of the n-1th hop + the bandwidth of the n-1th hop is less than or equal to the starting point of the nth hop (starting point of hop#n-1+BW of hop#n-1≤starting point of hop#n). Optionally, the value of the starting point can be an integer number of RBs.

[0281] Way four: define multiple reference points in one band, where each hop corresponds to a reference point. At the same time, the gNB / LMF configures the corresponding starting frequency point for each hop. The starting frequency point of each hop is the offset value of the corresponding reference point of the hop.

[0282] Point 2: Optionally, for SRS / PRS frequency hopping, the RB offset between two hops can be reported by the terminal. The gNB / LMF / LMF configures the relevant parameters according to the terminal capability based on point 1 to achieve the frequency hopping mode as shown in Figure 6.

[0283] Scheme two: for eMBB terminals that do not support intra-band CA, when performing SRS / PRS frequency hopping between multiple carrier units in the same frequency band, the overlapping resource block value between each two hops reuses the overlapping resource block value of the SRS / PRS frequency hopping of the terminal with reduced capability. The transmission of SRS or PRS on at least one of all hops may have discontinuous frequency domain resource allocation. A possible example is shown in the following figure with two hops occupying time-frequency domain resources.

[0284] Point 1: To achieve the SRS / PRS frequency hopping mode as shown in Figure 7, the following ways are considered:

[0285] The gNB / LMF configures an omitting resource for each hop, where the omitting resource is as the skipping part in FIG. 7, i.e., the reference signal is not transmitted in the omitting resource part when the reference signal is transmitted in the hop. The above omitting resource can be a non-integer RB, and / or the omitting resource can be a 0 value. Based on the omitting resource configured / indicated by the gNB / LMF, and / or the terminal determines the frequency domain resource location of each hop according to the RRC parameters configuration and the protocol preset rule of the start RB of the first hop, and the overlapping resource block. The omitting resource can be determined according to a common frequency resource reference point and an offset value relative to the common frequency resource reference point. The above common reference point can be preset by the protocol or indicated by the gNB / LMF. Each frequency band has a common reference point, and all omitting resources are based on the reference point for value. Alternatively, the omitting resource is an offset value relative to the start RB (the start RB is the current hop containing the overlapping resource block (the omitting resource can be a negative value) with other hops or not containing the resource block overlapping with other hops) or the ending RB (the ending RB is the current hop containing the resource block overlapping with other hops or not containing the resource block overlapping with other hops) of the current hop. The specific method is preset by the protocol.

[0286] Specifically, the terminal does not perform the transmission of the SRS or the reception of the PRS on the determined omitting resource.

[0287] In some embodiments, the bandwidth of each hop is configured by RRC, where the bandwidth of each hop remains the same. Alternatively, the total bandwidth (including the omitting resource) of each hop remains the same, or the number of available resources of each hop remains the same (excluding the omitting resource). Alternatively, the LMF / gNB can perform the indication of the effective bandwidth of each hop or the indication of the total bandwidth (including the omitting resource) of each hop based on the higher layer signaling.

[0288] Point 2: The support of the terminal for scheme one and scheme two depends on the terminal capability. One possible way is that scheme two can be the default capability of scheme one, that is, when the terminal does not support intra-band CA, the terminal reports the support of the intra-band CC of the SRS / PRS frequency hopping, and if the terminal does not report the support of the frequency hopping frequency domain resource determination mechanism shown in scheme one at the same time, it means that the terminal only supports the execution of the SRS / PRS reference signal frequency hopping based on scheme two. Accordingly, the gNB / LMF performs the parameter configuration related to the determination of the frequency hopping frequency domain resource based on scheme two.

[0289] Point 3: Optionally, for the first and second schemes, the intra-band CA can be continuous intra-band CA.

[0290] To sum up, the above embodiments of the present scheme propose a method for determining the bandwidth occupied by each hop when an eMBB terminal not supporting intra-band CA performs frequency hopping within the aggregated bandwidth occupied by the intra-band CA, so as to avoid data transmission on the guard band as much as possible and avoid causing inter-band interference.
