[0150] In the relevant 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. When SRS frequency hopping occurs, the random phase between the two hops cannot be consistent. Therefore, it is necessary to estimate the phase offset through the overlapping resource blocks (overlapping RB) between the two hops. However, when the number of overlapping resource blocks is too large, it will affect the total positioning bandwidth and the positioning accuracy. Therefore, for the estimation of overlapping resource blocks, it is necessary to make a reasonable value between the evaluation accuracy of the phase offset and the actual total bandwidth of the positioning signal. The final agreement sets the overlapping resource blocks to {0, 1, 2, 4}.

[0151] Among them, for the case where the value is "0", some companies have proposed that the performance gain provided by overlapping resource blocks only exists when the phase offset is large. When the phase offset is relatively small, the performance improvement of overlapping resource blocks can be ignored. The phase offset may be related to the stability performance of the terminal radio frequency (RF). Therefore, when the terminal reports the UE capability, it can first report the capabilities related to the phase offset. The gNB / LMF can determine the value of the overlapping resource block based on the UE capability report, for example, it can be 0.

[0152] Therefore, in the RECAP PRS / SRS frequency hopping of the PRS / SRS positioning reference signal of the reduced capability terminal, the terminal first reports the UE capability related to the overlapping resource blocks. The gNB / LMF performs the actual configuration of the overlapping resource blocks for the UE based on the reported parameters.

[0153] Optionally, the frequency hopping (R18 REDCAP PRS / SRS positioning frequency hopping) mechanism of the above-mentioned positioning reference signal can be introduced to the enhanced mobile broadband (eMBB) terminal that does not support uplink intra-band carrier aggregation (intra-band CA). After the introduction of this mechanism, the positioning accuracy of the eMBB UE that does not support intra-band CA can be enhanced, and the eMBB terminal can perform SRS / PRS frequency hopping between different carrier units (Component Carrier, CC) of intra-band CA to enhance its transmission bandwidth.

[0154] When an eMBB UE performs frequency hopping between intra-band CCs, one issue that needs 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, thereby avoiding inter-band interference to data transmission of other terminals.

[0155] In response to the above problems, the present disclosure proposes a communication method, which can determine the frequency domain position of a terminal that does not support in-band carrier aggregation when performing frequency hopping transmission. The specific content of the method is as follows.

[0156] Figure 2 FIG. 1 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. Figure 2 As shown, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The communication system 100 may include a terminal 101 and a network device 102. The method includes:

[0157] Step 2101: The terminal sends second information to the network device.

[0158] In some embodiments, the terminal may send second information to the network device, where the second information is used to indicate at least one of the following capabilities:

[0159] Whether the terminal supports sending 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 each two frequency hopping domain resources to be a negative value; whether the terminal supports the value of the frequency domain offset corresponding to each frequency hopping domain resource to be a positive value, and / or the value of the frequency domain offset is greater than or equal to the value of the protection band; the value of the frequency domain offset corresponding to each two frequency hopping domain resources supported by the terminal; the value of the overlapping frequency domain resources between each two frequency hopping domain resources supported by the terminal, which may be a negative value; the terminal supports sending the first reference signal and / or receiving the second reference signal in a frequency hopping manner using intra-band carrier aggregation intra-band CA; the terminal supports sending the first reference signal and / or receiving the second reference signal in a first frequency hopping manner using intra-band carrier aggregation intra-band CA, wherein, when the value of the second information is empty, it is assumed that the terminal supports sending the first reference signal and / or receiving the second reference signal in a second frequency hopping manner using intra-band carrier aggregation intra-band CA; the terminal supports sending the first reference signal and / or receiving the second reference signal in a frequency hopping manner using intra-band carrier aggregation intra-band The first mode and / or the second mode of CA frequency hopping sends a first reference signal and / or receives a second reference signal.

[0160] In other words, the terminal can report the terminal capabilities, for example, the terminal can report whether the terminal supports sending 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 capabilities reported by the terminal and configure relevant parameters for the terminal according to the capability information reported by the terminal. For example, when the terminal supports sending 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 configure parameters such as the bandwidth and frequency domain position of each hop when frequency hopping for the terminal.

[0161] In some embodiments, the terminal is a terminal that does not support intra-band carrier aggregation (ICA), wherein the ICA is continuous ICA.

[0162] In other words, the terminal may be a terminal that does not support continuous intra-band carrier aggregation. At this time, by determining the frequency domain position of each hop of the terminal during frequency hopping, it is possible to introduce a frequency hopping mechanism for the terminal that does not support continuous intra-band carrier aggregation. By adopting the frequency hopping mechanism to transmit the reference signal, the interference of the transmission signal during transmission can be reduced, thereby improving the accuracy of positioning based on the reference signal.

[0163] Step 2102a: the terminal determines the first information.

[0164] In some embodiments, the first information is used to indicate frequency domain resources for sending the first reference signal and / or receiving the second reference signal in a frequency hopping manner.

[0165] In some embodiments, after the terminal determines the first information, it can send 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 resources when frequency hopping is adopted, that is, the first information can indicate the terminal’s related parameters when sending the first reference signal and / or receiving the second reference signal in a frequency hopping manner, for example, the first information can indicate the frequency domain position and bandwidth of each hop, etc.

[0166] In some embodiments, optionally, the first reference signal may be an uplink reference signal, for example, a sounding reference signal SRS, which may be used for uplink positioning. When the first reference signal is a sounding reference signal SRS, the terminal may send the first reference signal to the network device.

[0167] In some embodiments, optionally, the second reference signal may be a downlink reference signal, for example, a positioning reference signal PRS, which may be used for downlink positioning. When the second reference signal is a positioning reference signal PRS, the network device may send the second reference signal to the terminal.

[0168] In some embodiments, the terminal can determine the first information based on the instructions of the network device or the protocol agreement, wherein the first information includes: the frequency domain offset corresponding to each frequency hopping domain resource when sending the first reference signal and / or receiving the second reference signal between multiple carrier units in the first frequency band.

[0169] In other words, the terminal can send the first reference signal and / or receive the second reference signal between multiple carrier units in the first frequency band, that is, the terminal can send the first reference signal and / or receive the second reference signal in the first frequency band by frequency hopping. Optionally, the terminal can receive the first information indicated by the network device, or can determine the first information according to the protocol agreement. At this time, the first information can be the frequency domain offset corresponding to each hop frequency domain resource. For example, the frequency domain offset corresponding to each hop frequency domain resource can be the frequency domain offset value of the N+1th hop relative to the Nth hop, that is, the frequency domain offset value between the two hops, or can be the frequency domain offset value of the N+1th hop relative to the reference point, that is, the frequency domain offset value of each hop relative to the reference point, etc. Optionally, according to the indication of the network device or the protocol agreement, the method for determining the first information can be any of the following.

[0170] Direction 1

[0171] Method 1

[0172] In some embodiments, determining the first information includes: determining the frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource based on first indication information of the network device, wherein the first indication information is used to indicate the value of the overlapping resource block between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource, the value of the overlapping resource block is a negative number, and N is a positive integer.

[0173] In some embodiments, the network device can indicate the frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource through the first indication information, where the value of the overlapping resource block can be the number of overlapping resource blocks, that is, the frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource, which can be an integer multiple of the overlapping resource block bandwidth.

[0174] In other words, the frequency domain offset between the two hops can be determined by configuring the number of overlapping resource blocks between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource, so as to determine the first information. At this time, the frequency domain offset corresponding to the two frequency hopping domain resources can be the frequency domain offset value of the N+1th hop relative to the Nth hop.

[0175] Optionally, the number of overlapping resource blocks can be configured as a negative number. In this case, there is no overlap between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource, and there is a gap between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource, that is, there is a frequency domain deviation, wherein the frequency domain deviation is an integer multiple of the bandwidth of the overlapping resource block. For example, when the number of overlapping resource blocks between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource is -2, the frequency domain deviation between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource is the length of two resource blocks.

[0176] In some embodiments, for example, the frequency domain deviation between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource needs to be greater than or equal to the bandwidth length of the guard band, so as to avoid transmitting the reference signal on the guard band. Specifically, the value of the overlapping resource block can be determined according to the length of the guard band, where the bandwidth of the guard band can be determined according to the following Table 1.

[0177] Table 1

[0178]

[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 the total bandwidth and the current subcarrier spacing.

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

[0181] In other words, the frequency domain deviation between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource must simultaneously satisfy two conditions: being greater than the protection band width, and being an integer multiple of the bandwidth of the overlapping resource block. That is, the frequency domain deviation between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource can be a bandwidth of an integer number of overlapping resource blocks that is greater than and closest to the protection band bandwidth. That is, the protection band bandwidth can be determined first, and then the number of overlapping resource blocks can be determined based on the bandwidth of the overlapping resource blocks. For example, when the bandwidth of 3 overlapping resource blocks is smaller than the bandwidth of the protection band, but the bandwidth of 4 overlapping resource blocks is larger than the bandwidth of the protection band, it can be determined that the value of the overlapping resource blocks is -4.

[0182] Method 2

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

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

[0185] In other words, the terminal can determine the frequency domain offset based on the value of the guard band between the first frequency hopping domain resource and the N+1th frequency hopping domain resource. For example, the value of the guard band between the first frequency hopping domain resource and the N+1th frequency hopping domain resource can be indicated by the network device or can be predefined by the protocol, and the present disclosure is not limited to this.

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

[0187] In some embodiments, the bandwidth occupied by the frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource is greater than or equal to the bandwidth occupied by the protection band between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource; or, the number of resource blocks RBs included in the frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource is greater than or equal to the number of RBs included in the protection band between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource; or, the number of RBs included in the frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource is greater than or equal to the number of RBs included in the maximum protection 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 protection band. For example, it can be determined that the above frequency domain offset is greater than or equal to the bandwidth of the protection band; or, the protection band can be determined according to the above Table 1 in the same way as the above method 1, and the number of overlapping resource blocks that are greater than and closest to the bandwidth of the protection band can be determined. The above frequency domain offset is determined according to the number of overlapping resource blocks. For example, when the number of overlapping resource blocks included in the protection band is greater than 3 and less than 4, it can be determined that the number of overlapping resource blocks that are greater than and closest to the bandwidth of the protection band is 4. At this time, the frequency domain offset can be the bandwidth of 4 overlapping resource blocks. ; Or, the frequency domain offset can also be determined as the bandwidth of an integer number of overlapping resource blocks, but the number of overlapping resource blocks can be greater than the number of overlapping resource blocks included in the maximum guard band. For example, the value of the maximum guard band can be determined according to Table 1, and the value of the maximum guard band is determined to be the bandwidth of how many overlapping resource blocks, and the frequency domain offset is determined according to the number of overlapping resource blocks included in the guard bandwidth. For example, when the number of overlapping resource blocks included in the maximum guard band is greater than 5 and less than 6, the number of overlapping resource blocks greater than and closest to the guard band bandwidth can be determined to be 6, and the frequency domain offset can be the bandwidth of 6 overlapping resource blocks.

[0189] Method 3

[0190] In some embodiments, determining the first information includes: 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 the offset of the starting point corresponding to each frequency hopping domain resource relative to a common frequency domain reference point; wherein, among every two frequency hopping domain resources, 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+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 hop domain resource. At this time, the frequency domain offset of each hop is the offset from the starting point to the common frequency domain reference point. Optionally, the corresponding starting point of each frequency hop domain resource configuration can be configured according to the number of overlapping resource blocks. Specifically, the starting point of the N-1th frequency hop domain resource can be determined according to the starting point of the N-1th hop, the bandwidth of the N-1 hop, and the number of overlapping resource blocks. For example, the number of overlapping resource blocks can be determined to be 2, and the end point of the N-1th frequency hop domain resource can be determined according to the starting point of the N-1th hop and the bandwidth of the N-1 hop. The frequency domain resource position of the terminal plus the frequency domain resource position after the bandwidth of 2 overlapping resource blocks can be determined as the starting point of the N-1th frequency hop 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+1th frequency hopping domain resource, that is, there is no overlap between the two frequency hopping domain resources.

[0194] In the above embodiments, the common frequency domain reference point may be predefined by the protocol, or may be configured for the terminal by the network device through a system message or a broadcast message, or may be configured for the terminal by the network device through Radio Resource Control (RRC) signaling, which is not limited in the present disclosure.

[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 a reference point corresponding to each frequency hopping domain resource in the first frequency band and a 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 a starting point corresponding to each frequency hopping domain resource and a 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 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 in the above method 3, the starting point corresponding to each frequency hopping domain resource configuration 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+1th 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 may be predefined by the protocol, or may be configured for the terminal by the network device through a system message or a broadcast message, or may be configured for the terminal by the network device through RRC signaling, which is not limited in the present disclosure.

[0200] Direction 2

[0201] Method 5

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

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

[0204] In other words, the first information may indicate a first frequency domain part on which the first reference signal is not sent and / or the second reference signal is not received, i.e., the first frequency domain part may be greater than or equal to the bandwidth of the protection band, thereby avoiding transmission of the reference signal on the protection band.

[0205] For example, there may be overlapping resource blocks between two frequency hopping domain resources of the method, for example, the Nth frequency hopping domain resource includes resource block 1, resource block 2 and resource block 3, and the N+1th frequency hopping domain resource includes resource block 3, resource block 4 and resource block 5, then the number of overlapping resource blocks between the Nth hop and the N+1th hop is 1. Optionally, at least one frequency hopping domain resource includes a first frequency domain part, and the first reference signal is not sent and / or the second reference signal is not received on the first frequency domain part, that is, the sending or receiving of the reference signal in one hop of the method may be discontinuous. For example, in the above example, the N+1th frequency hopping domain resource may include the first frequency domain part, that is, when the reference signal is sent or received in the N+1th hop, the reference signal is sent or received on other resources except the first frequency domain part, and the reference signal is not sent or received in the first frequency domain part.

[0206] In the above embodiment, the first frequency domain part can be determined according to the indication of the network device or the protocol agreement, wherein the first frequency domain part satisfies at least one of the following items: the number of RBs contained 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 upon by the protocol; the position of the first frequency domain part is determined according to the starting position of the Nth frequency hopping domain resource and the overlapping resource blocks between every two frequency hopping domain 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; the position of the first frequency domain part is determined according to the starting position or the ending position of the current frequency hopping domain 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 hop is the same, and for example, the bandwidth of each hop may include the first frequency domain part, or may not include the first frequency domain part. For example, the Nth frequency hopping domain resource does not include the first frequency domain part, and the bandwidth of the Nth frequency hopping domain resource is 20MHz, and the N+1th frequency hopping domain resource includes the first frequency domain part, that is, the resource bandwidth for sending and / or receiving the reference signal of the N+1th hop plus the bandwidth of the first frequency domain part may be equal to 20MHz, or the resource bandwidth for sending and / or receiving the reference signal of the N+1th hop is 20MHz.

[0208] In some embodiments, when the terminal reports that it supports sending a first reference signal and / or receiving a 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 above-mentioned method 5 can be used to determine the first information, and send the first reference signal and / or receive the second reference signal 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-mentioned methods 1 to 5, and the first reference signal can be sent and / or the second reference signal can be received in a frequency hopping manner based on the first information.

[0209] Alternatively, the terminal may directly report whether the terminal supports the overlapping resource blocks between each two frequency hopping domain resources to take a negative value. When the terminal supports the overlapping resource blocks between each two frequency hopping domain resources to take a negative value, the method of the above-mentioned method 1 may be used to determine the first information, and send the first reference signal and / or receive the second reference signal in a frequency hopping manner based on the first information; alternatively, the terminal may report whether the terminal supports the frequency domain offset corresponding to each frequency hopping domain resource to take a positive value, and / or the value of the frequency domain offset is greater than or equal to the value of the protection band. If the terminal supports this capability, the network device may configure the corresponding frequency domain offset for the terminal according to the capability of the terminal, and the terminal may configure the corresponding frequency domain offset for the terminal according to the frequency domain offset configured by the network device. The terminal may determine the first information by the shift amount, and send the first reference signal and / or receive the second reference signal in a frequency hopping manner based on the first information; or, the terminal may report the value of the frequency domain offset corresponding to each two frequency hopping domain resources supported by the terminal, and the network device may configure the frequency domain offset for the terminal according to the value of the frequency domain offset supported by the terminal; or, the terminal may report the value of the overlapping frequency domain resources between each two frequency hopping domain resources supported by the terminal, which may be a negative value, and the network device may configure the value of the overlapping frequency domain resources for the terminal according to the value of the overlapping frequency domain resources between each two frequency hopping domain resources supported by the terminal; or, the terminal may report that the terminal supports intra-band carrier aggregation. The first reference signal and / or the second reference signal are sent in a CA frequency hopping manner. At this time, the network device can configure the corresponding frequency hopping parameters for the terminal according to the capability of the terminal, so that the terminal can send the first reference signal and / or receive the second reference signal in a frequency hopping manner based on the frequency hopping parameters; or, the terminal can report that the terminal supports the first manner of sending the first reference signal and / or receiving the second reference signal in intra-band CA frequency hopping, wherein when the value of the second information is empty, it is assumed that the terminal supports the second manner of sending the first reference signal and / or receiving the second reference signal in intra-band CA frequency hopping, that is, the second information can indicate that the terminal supports the method in the first manner or the method in the second manner; or, the terminal can report that the terminal supports the first manner and / or the second manner of sending the first reference signal and / or receiving the second reference signal in intra-band CA frequency hopping, that is, the terminal can report that the terminal supports both the method in the first manner and the method in the second manner.

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

[0211] Step 2102b: The network device determines the first information.

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

[0213] Optionally, the network device may configure the first information for the terminal according to the capability of the terminal. For example, when the terminal reports its own capability to support sending the first reference signal and / or receiving the second reference signal in a frequency hopping manner using intra-band carrier aggregation (CA), and the terminal supports allowing discontinuous sending or receiving of reference signals on at least one frequency domain resource (second mode), the network device may configure the value of the first frequency domain part on the frequency domain resource for the terminal, and the terminal does not send the first reference signal and / or does not receive the second reference signal on the first frequency domain part.

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

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

[0216] In some embodiments, the network device may 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 domain resource when sending a first reference signal and / or receiving a second reference signal between multiple carrier units in a first frequency band.

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

[0218] In some embodiments, the method also includes: configuring overlapping resource blocks between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource for the terminal, wherein the first information is a frequency domain offset between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource, and the frequency domain offset is determined based on the overlapping resource blocks between the Nth frequency hopping domain resource and the N+1th frequency hopping domain resource.

[0219] In other words, the network device can be predetermined to determine the first information according to the protocol and configure the first information for the terminal, or the network device can configure parameters related to the first information for the terminal. For example, the network device can determine the overlapping resource blocks between the Nth frequency hopping domain resources and the N+1th frequency hopping domain resources, and configure the overlapping resource blocks between the Nth frequency hopping domain resources and the N+1th frequency hopping domain resources for the terminal. The terminal can determine the frequency domain offset between the Nth frequency hopping domain resources and the N+1th frequency hopping domain resources based on the overlapping resource blocks between the Nth frequency hopping domain resources and the N+1th frequency hopping domain resources, that is, the terminal can determine the first information according to the parameters configured by the network device.

[0220] In some embodiments, the specific method for the network device to determine the first information is the same as the method for the terminal to determine the first information. For example, refer to method 1 to method 5 in step 2102a. The network device can configure relevant parameters for the terminal according to any of the above methods to facilitate the terminal to determine the first information, or the network device can determine the first information based on relevant parameters, etc., which will not be repeated here.

[0221] Step 2103: The terminal sends 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 sending or receiving the reference signal based on the first information, and the terminal and / or the network device can receive and / or send the reference signal in a frequency hopping manner at the frequency domain position indicated by the first information.

[0223] In some embodiments, optionally, the reference signal may be a first reference signal. When the reference signal is the first reference signal, for example, when the reference signal is a sounding reference signal SRS, the sounding reference signal SRS is used for uplink positioning, and the terminal may send 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 a second reference signal, the terminal may receive the second reference signal in a frequency hopping manner. In this case, this step is optional.

[0225] Step 2104: The network device sends a 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 for sending or receiving the reference signal based on the first information, and the terminal and / or the network device can receive and / or send the reference signal in a frequency hopping manner at the frequency domain position indicated by the first information.

[0227] In some embodiments, optionally, the reference signal may be a second reference signal. When the reference signal is the second reference signal, for example, when the reference signal is a positioning reference signal PRS, the positioning reference signal PRS is used for downlink positioning, and the network device may send 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 a first reference signal, the network device may receive the first reference signal in a frequency hopping manner. In this case, this step is optional.

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

[0271] The method shown in the embodiment of the present disclosure proposes a method for determining the bandwidth occupied by each hop when an eMBBUE that does not support intra-band carrier aggregation (intra-band CA) performs frequency hopping within the aggregated bandwidth occupied by intra-band carrier aggregation, so as to avoid data transmission on the protection band as much as possible to avoid inter-band interference. The complete content of the method is as follows.

[0272] Solution 1: For eMBB terminals that do not support intra-band CA, when performing SRS / PRS frequency hopping between multiple carrier elements in the same band, a certain frequency offset is allowed between each two hops. A possible example is that the time-frequency domain resources occupied by the two hops are as follows: Figure 6 shown.

[0273] Point 1: To achieve Figure 6 The SRS / PRS frequency hopping method shown considers at least one of the following methods:

[0274] Method 1: The resource block offset (RB offset) between two hops is configured through overlapping RB. For example, the overlapping RB value may be a negative value, and a possible value in the FR1 frequency 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 that is greater than and closest to the values ​​under the configurations in the above Table 1. In the following table, the value of the protection band is determined based on the maximum value of the bandwidth of the lowest frequency point and the bandwidth of the highest frequency point, or the value of the protection band is determined based on the maximum value of the entire bandwidth and the current subcarrier spacing.

[0276] Method 2: Configure a frequency domain offset (FDO), where the frequency domain offset is a 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, FDO is an integer number of RBs greater than and closest to the values ​​under each configuration in the above table; alternatively, the RB value is 0, that is, the FDO value is the value of 0 RBs, that is, the FDO value is 0; alternatively, the FDO value may be the FDO value preset in the protocol, in which case the FDO value is greater than or equal to the maximum value in the above table (optionally, it may be an integer number of RBs).

[0279] Method 3: Each frequency band defines a common reference point in the frequency domain, and the gNB / LMF configures the corresponding starting point for each hop. Optionally, the offset value of the starting frequency of each hop relative to the common reference point can be configured, and the starting frequency of each hop is determined according to the offset value.

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

[0281] Method 4: Multiple reference frequency points are defined in a band, where each hop corresponds to a reference frequency 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 frequency point of the hop.

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

[0283] Solution 2: For eMBB terminals that do not support intra-band CA, when SRS / PRS frequency hopping is performed between multiple carrier units in the same frequency band, the overlapping resource blocks between each two hops are reused to reduce the value of the overlapping resource blocks in the SRS / PRS frequency hopping of the terminal. The transmission of SRS or PRS on at least one hop in all the frequency hopping may have discontinuous frequency domain resource allocation. A possible example takes two hops as an example. The time-frequency domain resources occupied by the two hops are shown in the following figure.

[0284] Point 1: To achieve Figure 7 The SRS / PRS frequency hopping method shown in the figure considers the following methods:

[0285] The gNB / LMF configures an omitting resource for each hop, where the omitting resource is as follows: Figure 7 The skipping part, that is, when the reference signal is transmitted in this hop, the omitted resource part needs to be skipped, and the reference signal is not transmitted in the omitted resource part. The omitted resources mentioned above may be non-integer multiples of RBs, and / or the omitted resources may be 0 values. The frequency domain resource position of each hop is determined based on the omitted resources configured / indicated by the gNB / LMF, and / or the terminal determines the frequency domain resource position of each hop according to the RRC parameter configuration such as the starting resource block position (start RB of thefirst hop) overlapping resource blocks and the protocol preset rules. The omitted resources can be determined based on the common frequency resources reference point and the offset value relative to the common frequency resources reference point. The above common reference frequency point can be preset by the protocol, or indicated by the gNB / LMF. Each frequency band has a common reference frequency point, and all omitted resources are based on the reference frequency point. Alternatively, the omitted resources are offset values ​​relative to the starting resource block of the current hop (the starting resource block is a resource block on the current hop that includes overlapping resource blocks with other hops (the omitted resources may be a negative value) or does not include resource blocks overlapping with other hops) or the ending resource block (ending RB) (the ending RB is a resource block on the current hop that includes overlapping resource blocks with other hops or does not include resource blocks overlapping with other hops), and the specific method is preset by the protocol.

[0286] Specifically, the terminal does not send the SRS or receive the PRS on the determined omitted resources.

[0287] In some embodiments, the bandwidth of each hop is configured by RRC, wherein the bandwidth of each hop remains the same. Optionally, the total bandwidth of each hop (including omitted resources) remains the same, or the number of available resources of each hop remains the same (excluding omitted resources). Optionally, the LMF / gNB can indicate the effective bandwidth of each hop based on high-layer signaling, or indicate the total bandwidth of each hop (including omitted resources).

[0288] Point 2: Optionally, the terminal's support for Scheme 1 and Scheme 2 depends on the terminal's capabilities. One possible approach is that Scheme 2 can be used as the default capability for Scheme 1, that is, when a terminal that does not support intra-band CA reports support for frequency hopping of SRS / PRS of an intra-band carrier unit (intra-band CC), if the terminal does not simultaneously report support for the frequency hopping frequency domain resource determination mechanism shown in Scheme 1, it indicates that the terminal only supports frequency hopping of SRS / PRS reference signals based on Scheme 2. Accordingly, the gNB / LMF configures parameters related to frequency hopping frequency domain resource determination based on Scheme 2.

[0289] Point 3: Optionally, for Solution 1 and Solution 2, intra-band CA may be continuous intra-band CA.

[0290] In summary, the above embodiments of the present solution propose a method for determining the bandwidth occupied by each hop when an eMBB terminal that does not support intra-band CA performs frequency hopping within the aggregated bandwidth occupied by intra-band CA, so as to avoid data transmission on the protection band as much as possible to avoid inter-band interference.
