It should be noted that the embodiment shown in fig. 3 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, terminals may communicate via frequency hopping (Frequency Hopping, FH), e.g., the Redcap terminals described above may communicate based on frequency hopping, thereby enabling communication over a larger bandwidth if a smaller bandwidth is supported.

In some embodiments, the terminal may measure the positioning reference signal by frequency hopping when measuring the positioning reference signal.

The positioning reference signal resources include a plurality of positioning reference signal frequency hopping resources within a bandwidth range. The bandwidth ranges corresponding to the frequency hopping resources in the frequency domain may be the same or different, and the bandwidth range corresponding to each frequency hopping resource in the frequency domain is less than or equal to the maximum bandwidth supported by the terminal. The different frequency hopping resources may or may not overlap in the frequency domain. The different frequency hopping resources may have time intervals in the time domain, e.g., referred to as time gap, which may be set as desired, which is not limiting to the present disclosure.

Since the bandwidth range corresponding to each frequency hopping resource in the frequency domain is smaller than or equal to the maximum bandwidth supported by the terminal, the terminal can respectively measure the positioning reference signals on a plurality of positioning reference signal frequency hopping resources.

In some embodiments, the request information may explicitly instruct the terminal to transmit location information determined by measuring the positioning reference signal in a frequency hopping manner to the network device. After receiving the request information, the terminal can determine that the positioning reference signal needs to be measured in a frequency hopping mode according to the request information, and send the obtained position information to the network equipment.

In some embodiments, the request information may not explicitly instruct the terminal to transmit location information determined by measuring the positioning reference signal in a frequency hopping manner to the network device. For example, in the case that the terminal has received the frequency hopping configuration (may also be referred to as frequency hopping information) of the positioning reference signal, when the request information is received again, the positioning reference signal may be measured by default in a frequency hopping manner, and the resulting location information may be transmitted to the network device. In some embodiments, the network device carries a frequency hopping configuration that can carry positioning reference signals in positioning assistance information to the terminal.

As shown in fig. 4, the bandwidth range of the positioning reference signal resources includes 3 positioning reference signal frequency hopping resources, which are PRS fh#1, PRS fh#2, and PRS fh#3, and the bandwidth ranges corresponding to PRS fh#1, PRS fh#2, and PRS fh#3 in the frequency domain are mainly the same.

For example, the BandWidth (BandWidth) supported by the terminal is bw#1, the corresponding BandWidth ranges of PRS fh#1, PRS fh#2, PRS fh#3 in the frequency domain are equal to bw#1, and the terminal can measure PRS fh#1, PRS fh#2, and PRS fh#3 in a frequency hopping manner, thereby obtaining the location information.

It can be seen that, in the embodiment of the present disclosure, the terminal may measure PRS in a larger bandwidth range, which is beneficial to ensuring accuracy of location information, and thus, accuracy of determining a location of the terminal by the network device according to the location information, relative to the terminal that measures PRS only on bw#1.

In some embodiments, the request information sent by the network device to the terminal for requesting the terminal to send the location information may also be used to request the terminal to send frequency hopping information used in determining the location information.

In this embodiment, the request information may be used for requesting the terminal to transmit the location information, and for requesting the terminal to transmit frequency hopping information used when determining the location information. After receiving the request information, the terminal may send location information determined by measuring the positioning reference signal in a frequency hopping manner to the network device, and send frequency hopping information used when determining the location information to the network device.

In some embodiments, the network may send request information to the terminal requesting the terminal to send frequency hopping information used in determining location information.

This embodiment may be implemented independently of the embodiment shown in fig. 3, i.e. the request information is only used for requesting the terminal to send the frequency hopping information used when determining the location information, and is not used for requesting the terminal to measure the positioning reference signal by frequency hopping. After receiving the request information, the terminal may send frequency hopping information used in determining the location information to the network device.

In the above-described embodiment, although the network device may transmit the first frequency hopping information used in determining the location information to the terminal, the second frequency hopping information used in subsequently determining the location information by the terminal may be the same as or different from the first frequency hopping information.

For example, the first frequency hopping information sent by the network device to the terminal is used to instruct the terminal to measure the positioning reference signals sent by the plurality of transmitting and receiving points (Transmission and Receiving Point, TRP) in a frequency hopping manner, but the terminal can only actually measure the positioning reference signals sent by part of the TRPs in the frequency hopping manner, so that the second frequency hopping information used by the terminal in determining the positioning information is different from the first frequency hopping information.

Therefore, the request information sent by the network device to the terminal can be used for requesting the terminal to send the frequency hopping information used when determining the position information to the network device, so that the network device can accurately determine the frequency hopping information used when determining the position information by the terminal. For example, after the network device receives the position information determined by the terminal by measuring the positioning reference signal in the frequency hopping manner, the network device can more accurately determine the meaning of the position information according to the frequency hopping information used when the terminal is to determine the position information, and further accurately determine the position of the terminal according to the position information.

For example, the first frequency hopping information sent by the network device to the terminal is used to instruct the terminal to measure the positioning reference signals sent by tpr#1, tpr#2, tpr#3, tpr#4 in a frequency hopping manner, but the terminal can actually measure the positioning reference signals sent by tpr#1, tpr#2, tpr#3 only in a frequency hopping manner. The network device requests the terminal to send the frequency hopping information used when determining the position information to the network device through the request information, so that the position information can be accurately determined by the terminal measuring the positioning reference signals sent by the TPR#1, the TPR#2 and the TPR#3 through a frequency hopping mode, but not by the terminal measuring the positioning reference signals sent by the TPR#1, the TPR#2, the TPR#3 and the TPR#4 through the frequency hopping mode.

In some embodiments, the frequency hopping information includes at least one of:

the method comprises the steps that a transmitting and receiving point with the allocated positioning reference signal frequency hopping resource is used for indicating a terminal to determine the transmitting and receiving point with the allocated positioning reference signal frequency hopping resource used by the position information in a frequency hopping mode;

the positioning reference signal resource set identifier is used for indicating a terminal to determine a positioning reference signal resource set to which positioning reference signal frequency hopping resources used for position information belong in a frequency hopping mode;

the positioning reference signal resource identifier is used for indicating the positioning reference signal frequency hopping resource used by the terminal for determining the position information in a frequency hopping mode;

the frequency hopping mode information is used for indicating a frequency hopping mode used by the terminal for determining the position information through the frequency hopping mode, for example, the frequency hopping mode information is used for indicating the determined position information obtained by measuring the positioning reference signal through a single frequency hopping mode or the determined position information obtained by indicating the positioning reference signal through a multi-frequency hopping mode.

In some embodiments, the request information includes first indication information for indicating at least one of:

For example, the positioning reference signal resources shown in fig. 4 are taken as an example, and include 3 positioning reference signal frequency hopping resources.

When the first indication information in the request information indicates the terminal to measure the positioning reference signal on a plurality of positioning reference signal hopping resources, the terminal can measure the positioning reference signal on any 2 hopping resources in the 3 hopping resources according to the first indication information.

When the first indication information in the request information indicates the terminal to measure the positioning reference signal on the first positioning reference signal frequency hopping resource, the terminal can measure the positioning reference signal on any 1 frequency hopping resource in the 3 frequency hopping resources according to the first indication information.

When the first indication information in the request information indicates the terminal to measure the positioning reference signal on each positioning reference signal hopping resource, the terminal can measure the positioning reference signal on each of the 3 hopping resources according to the first indication information.

In some embodiments, the first indication information includes at least one of:

transmitting a receiving point identification (TRP ID);

positioning reference signal identification (PRS ID);

cell identity, e.g. physical cell identity (Physical Cell Identifier, PCI), cell global identity (cell global ID);

Frequency domain identification, such as absolute radio channel number (Absolute Radio Frequency Channel Number, ARFCN);

a positioning reference signal resource set identification (PRS resource set ID);

positioning reference signal resource identification (PRS resource ID);

a frequency hopping identifier (for example, a positioning reference signal frequency hopping index (PRS frequency hopping index)) for instructing the terminal to measure the positioning reference signal on a positioning reference signal frequency hopping resource corresponding to the frequency hopping identifier;

the multi-hop identifier is used for indicating the terminal to measure the positioning reference signal on each positioning reference signal frequency hopping resource;

and the single-hop identifier is used for indicating the terminal to measure the positioning reference signal on one positioning reference signal frequency hopping resource.

For example, the first indication information may indicate a TRP ID, and the terminal may measure PRS transmitted by a TRP corresponding to the TRP ID in a frequency hopping manner to obtain location information.

For example, the first indication information may indicate a PRS ID, and the terminal may measure PRS corresponding to the PRS ID in a frequency hopping manner to obtain location information. In some embodiments, the PRS ID may also be used to determine a TRP, in which case, the terminal may measure PRS transmitted by the TRP corresponding to the PRS ID in a frequency hopping manner to obtain location information.

For example, the first indication information may indicate a cell identifier, and the terminal may measure PRS in a cell corresponding to the cell identifier by using a frequency hopping manner to obtain location information.

For example, the first indication information may indicate a frequency domain identifier, and the terminal may measure PRS in a frequency domain range corresponding to the frequency domain identifier by using a frequency hopping manner to obtain location information.

For example, the first indication information may indicate PRS resource set ID, and the terminal may measure PRS on PRS resources included in PRS resource set corresponding to PRS resource set ID in a frequency hopping manner to obtain location information.

For example, the first indication information may indicate a PRS resource ID, and the terminal may measure PRS on a PRS resource corresponding to the PRS resource ID in a frequency hopping manner to obtain location information.

For example, the first indication information may indicate a frequency hopping identifier, and the terminal may measure the positioning reference signal on a positioning reference signal frequency hopping resource indicated by the frequency hopping identifier among a plurality of positioning reference signal frequency hopping resources within a bandwidth range of the positioning reference signal resource, so as to obtain the location information.

For example, the first indication information may indicate a multi-hop identity, and the terminal may measure the positioning reference signal on each positioning reference signal hopping resource among a plurality of positioning reference signal hopping resources within a bandwidth range of the positioning reference signal resource to obtain the location information.

For example, the first indication information may indicate a single hop identifier, and the terminal may measure the positioning reference signal on one positioning reference signal hopping resource among a plurality of positioning reference signal hopping resources within a bandwidth range of the positioning reference signal resource, so as to obtain the location information.

In some embodiments, the location information includes at least one of: measuring results of positioning reference signals; information of the terminal position.

The measurement result of the positioning reference signal is an intermediate result for determining the position of the terminal, and can be sent to the network device by the terminal, and the network device determines the position of the terminal according to the measurement result of the positioning reference signal.

For example, the measurement results of the positioning reference signals include at least one of: reference signal received power (Reference Signal Received Power, RSRP) Of the positioning reference signal, reference signal path received power (Reference Signal Received Path Power, RSRPP) Of the positioning reference signal, terminal receive transmit Time difference (UE Rx-Tx Time difference), reference signal Time difference (Reference Signal Time Difference, RSTD), time Of Arrival (TOA).

For example, the location information may include measurement results of the positioning reference signals, and the terminal may transmit the measurement results of the positioning reference signals to the network device, which determines the location of the terminal based on the measurement results of the positioning reference signals. For example, the location information may include information of a location of the terminal, and the terminal may determine the location of the terminal according to a measurement result of the positioning reference signal, and then transmit the information of the location of the terminal to the network device, so that the network device learns the location of the terminal.

In some embodiments, the request information requests that the location information sent by the terminal include a measurement result of the first type, and the request information is further used to instruct the terminal to measure the positioning reference signal using a frequency hopping manner corresponding to the measurement result of the first type.

The request information sent by the network device to the terminal may be used to request the terminal to send a first type of measurement result to the network device, e.g. the network device may determine the location of the terminal by determining a time difference of arrival (DL-TDOA (Time Difference of Arrival)), e.g. the type of measurement result comprises at least one of the following: RSRP, RSRPP, RSTD.

The request information may also be used to request the terminal to measure the positioning reference signal using a frequency hopping pattern corresponding to the first type of measurement result. It should be noted that, the first type may be one type or multiple types, and when the first type is one type, the request may be used to request the terminal to measure the positioning reference signal using the frequency hopping manner corresponding to the measurement result of the type; when the first type is a plurality of types, then the request may be used to request the terminal to measure the positioning reference signal using the frequency hopping manner respectively corresponding to the plurality of types of measurement results.

For example, the frequency hopping scheme corresponding to RSRP is single-hop, and the frequency hopping scheme corresponding to RSTD is multi-hop.

When the request information is used for requesting the terminal to send the RSRP measurement result to the network device, the request information may also be used for instructing the terminal to measure the positioning reference signal using a frequency hopping manner corresponding to the RSRP, that is, a single frequency hopping manner, and then the terminal may measure the positioning reference signal using the single frequency hopping manner, for example, measure the positioning reference signal on one positioning reference signal frequency hopping resource within a bandwidth range of the positioning reference signal resource, and send the obtained RSRP to the network device.

When the request information is used to request the terminal to send the RSTD measurement result to the network device, the request information may also be used to instruct the terminal to measure the positioning reference signal using the frequency hopping mode corresponding to the RSTD, that is, the multi-frequency hopping mode, and then the terminal may measure the positioning reference signal using the multi-frequency hopping mode, for example, measure the positioning reference signal on each positioning reference signal frequency hopping resource within the bandwidth range of the positioning reference signal resource, and send the obtained RSTD to the network device.

It should be noted that, in some embodiments, the correspondence between the type of the measurement result and the frequency hopping manner may be indicated to the terminal in advance by the network device, so that the request information only needs to request the location information sent by the terminal to include the measurement result of the first type, and the terminal can determine that the positioning reference signal needs to be measured by using the frequency hopping manner corresponding to the measurement result of the first type; or, the corresponding relation between the type of the measurement result and the frequency hopping mode is not indicated to the terminal, so that when the network equipment needs to request that the position information sent by the terminal includes the measurement result of the first type, the frequency hopping mode corresponding to the measurement result of the first type can be determined, and further the request information is set to be further used for indicating the terminal to measure the positioning reference signal by using the frequency hopping mode corresponding to the measurement result of the first type.

In some embodiments, the location information includes a measurement result of the positioning reference signal, and the information transmission method further includes: and receiving a measurement result and second indication information sent by the terminal, wherein the second indication information is used for indicating frequency hopping information used for determining the measurement result.

In some embodiments, in the case where the location information includes a measurement result of the positioning reference signal, for example, when the request information is used to request that the location information transmitted by the terminal includes a measurement result of the positioning reference signal, since the measurement result is associated with information of TRP, when the network device receives the measurement result, it may be determined which one or more TRP is/are measured by the received measurement result, and it may also be determined which one or more TRP is/are configured by the frequency hopping information used by the terminal to determine the measurement result.

Accordingly, the network device may not necessarily indicate the TRP in which the frequency hopping information is configured when transmitting the frequency hopping information used to determine the measurement result to the network device. For example, the terminal may send second indication information to the network device, where the second indication information may indicate the network device, and the terminal determines frequency hopping information used by the measurement result.

In some embodiments, the location information includes information of a location of the terminal, and the information transmission method further includes: receiving information of a terminal position and third indication information sent by a terminal, wherein the third indication information is used for indicating at least one of the following: and determining the frequency hopping information used by the position information of the terminal and the transmitting and receiving point where the frequency hopping information is configured.

In some embodiments, in the case where the location information includes information of the location of the terminal, for example, when the request information is used to request that the location information transmitted by the terminal includes information of the location of the terminal, since the information of the location of the terminal does not correlate with information of TRP, when the network device receives the measurement result, it cannot be determined which one or more TRP transmitted measurement positioning reference signals are measured by the received measurement result, nor can it be determined which one or more TRP the frequency hopping information used by the terminal to determine the measurement result is configured on.

Accordingly, the network device may indicate the TRP in which the frequency hopping information is configured when transmitting the frequency hopping information used to determine the measurement result to the network device. For example, the terminal may send third indication information to the network device, where the second indication information may indicate the network device, the terminal determines frequency hopping information used by the measurement result, and may also indicate a TRP where the frequency hopping information is configured. Thereby enabling the network device to determine which one or more TRPs the received measurement result was obtained by measuring the measurement positioning reference signal transmitted by and to determine which one or more TRPs the terminal is configured with the frequency hopping information used to determine the measurement result.

In a second aspect, embodiments of the present disclosure provide an information receiving method. Fig. 5 is a schematic flow chart diagram illustrating an information receiving method according to an embodiment of the present disclosure. The information receiving method shown in the present embodiment may be performed by a terminal.

As shown in fig. 5, the information receiving method may include the steps of:

in step S501, request information sent by a network device is received, where the request information is used to request a terminal to send location information, and the location information is determined by measuring a positioning reference signal in a frequency hopping manner.

It should be noted that the embodiment shown in fig. 5 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, terminals may communicate via Frequency Hopping (FH), e.g., the Redcap terminals described above may communicate based on frequency hopping, thereby enabling communication over a larger bandwidth if a smaller bandwidth is supported.

According to the embodiment of the disclosure, the terminal can receive the request information sent by the network equipment, so as to determine the position information according to the request information in a frequency hopping mode and send the position information to the network equipment. The terminal obtains the position information by measuring the positioning reference signal in a frequency hopping mode, so that the positioning reference signal can be measured in a larger frequency domain range to determine the position information, the accuracy of the position information is guaranteed, and the network equipment is guaranteed to determine the position accuracy of the terminal according to the position information.

This embodiment may be implemented independently of the embodiment shown in fig. 5, i.e. the request information is only used for requesting the terminal to send the frequency hopping information used when determining the location information, and is not used for requesting the terminal to measure the positioning reference signal by frequency hopping. After receiving the request information, the terminal may send frequency hopping information used in determining the location information to the network device.

For example, the network device sends first frequency hopping information to the terminal, which is used to instruct the terminal to measure the positioning reference signals sent by the plurality of Transmission Receiving Points (TRPs) in a frequency hopping manner, but the terminal can only actually measure the positioning reference signals sent by part of the TRPs in the frequency hopping manner, so that the second frequency hopping information used when the terminal determines the positioning information is different from the first frequency hopping information.

the frequency hopping mode information is used for indicating a frequency hopping mode used by the terminal for determining the position information through the frequency hopping mode, for example, indicating the determined position information obtained by measuring the positioning reference signal through a single frequency hopping mode or indicating the determined position information obtained by measuring the positioning reference signal through a multi-frequency hopping mode.

In some embodiments, the first indication information includes at least one of:

transmitting a receiving point identifier;

positioning reference signal identification;

cell identification;

frequency domain identification;

positioning a reference signal resource set identifier;

positioning a reference signal resource identifier;

the frequency hopping identifier is used for indicating the terminal to measure the positioning reference signal on the positioning reference signal frequency hopping resource corresponding to the frequency hopping identifier;

For example, the first indication information may indicate a frequency hopping identity, and the terminal may measure a positioning reference signal on a positioning reference signal frequency hopping resource indicated by the frequency hopping identity to obtain the location information.

For example, the first indication information may indicate a multi-hop identity, and the terminal may measure the positioning reference signal on each positioning reference signal hopping resource within a bandwidth range of the positioning reference signal resource to obtain the location information.

For example, the first indication information may indicate a single hop identity, and the terminal may measure the positioning reference signal on one positioning reference signal hopping resource within a bandwidth range of the positioning reference signal resource to obtain the location information.

For example, the measurement results of the positioning reference signals include at least one of: reference Signal Received Power (RSRP) of a positioning reference signal, reference signal path received power RSRPP of a positioning reference signal, terminal reception transmit time difference (UE Rx-Tx time difference), reference Signal Time Difference (RSTD), time of arrival (TOA).

The device, e.g. the network device, may determine the terminal location by means of a defined time difference of arrival (DL-TDOA (Time Difference of Arrival)), e.g. the type of measurement comprises at least one of the following: RSRP, RSRPP, RSTD.

In some embodiments, the location information comprises measurement results of positioning reference signals, and the information transmitting further comprises: and sending the measurement result and second indication information to the network equipment, wherein the second indication information is used for indicating frequency hopping information used for determining the measurement result.

In some embodiments, the location information includes information of a location of the terminal, and the information transmission method further includes: transmitting information of the terminal position and third indication information to the network equipment, wherein the third indication information is used for indicating at least one of the following: and determining the frequency hopping information used by the position information of the terminal and the transmitting and receiving point where the frequency hopping information is configured.

In some embodiments, the information sending method further includes: and determining a first transmitting and receiving point which is not configured with the positioning reference signal frequency hopping resource, and not measuring the positioning reference signal sent by the first transmitting and receiving point.

The terminal may determine which TRPs are configured with positioning reference signal hopping resources, wherein for a first TRP not configured with positioning reference signal hopping resources, the terminal may not measure the positioning reference signal sent by the first TPR. Because the first TPR is not configured with the positioning reference signal frequency hopping resource, when the maximum bandwidth supported by the terminal is relatively smaller, PRS can only be measured in a relatively smaller bandwidth range on the first TPR, and the accuracy of the obtained measurement result is lower, so that the network device is easy to determine the accuracy of the terminal position according to the measurement result, and therefore, the positioning reference signal sent by the first TPR can not be measured, which is beneficial to avoiding the technical problem.

In some embodiments, the terminal may determine a second transmission receiving point configured with a positioning reference signal frequency hopping domain resource, and measure the positioning reference signal sent by the second transmission receiving point in a frequency hopping manner. That is, the terminal only measures the positioning reference signal sent by the second TRP configured with the positioning reference signal frequency hopping domain resource, and when the maximum bandwidth supported by the terminal is relatively smaller, the PRS can be measured in a relatively larger bandwidth range on the second TPR by the frequency hopping mode, which is beneficial to ensuring the accuracy of the obtained measurement result and further to ensuring the accuracy of the network equipment to determine the position of the terminal according to the measurement result.
