In a terahertz frequency band, the carrier bandwidth of a wireless signal can reach more than dozens of GHz. Due to the fact that frequency differences of different subcarriers in a bandwidth are large, when a base station sends a large-bandwidth signal in a beam forming mode, beam directions of the signal can deviate on the different subcarriers, and therefore when a beam splitting phenomenon occurs and downlink AoD positioning measurement is conducted in a terahertz frequency band, if the bandwidth occupied by PRS (positioning reference signal) resources is large, each PRS resource corresponds to one downlink AoD range.

For example, the number of access point devices, the number of terminals, the number of access network devices, the number of core network devices, and the like in the communication system are not limited in the embodiments of the present application.

A terminal in the embodiments of the present application may refer to various forms of UE, access terminal, subscriber unit, subscriber station, mobile station, MS (mobile station), remote station, remote terminal, mobile device, user terminal, terminal device (terminal equipment), wireless communication device, user agent, or user equipment.

The access network device in the embodiment of the present application may be a device that provides an interface for a terminal or an access point device to access a communication network. For example, the access network device may be a base station, such as a 5G base station, a gnb (generation nodeb), or a base station in a next generation wireless communication system, which is not limited herein.

An example access point device may be an AP (access point), a TRP (transmission reception point), for example, a 5G AP, h (e) NB, TRP, etc.

In a wireless communication system, there are many common positioning methods, such as TDOA and RTT positioning based on timing measurement, AoD and AoA positioning based on angle measurement, and the like. The positioning method based on the downlink AoD measures and feeds back downlink AoD information of a plurality of TRPs to the target UE through the target UE, and the position of the target UE can be uniquely determined by combining the position coordinates of the TRPs.

In an NR system, a network side configures at least one PRS resource sent by a TRP to a target UE, each PRS resource is sent in a beam forming mode, and at the moment, each PRS (positioning reference signal) resource corresponds to one downlink AoD; the target UE measures PRS resources and reports a PRS resource index with the maximum RSRP and an RSRP value thereof to a network side; and the network side maps the reported PRS resource index to obtain the downlink AoD between each TRP and the target UE. In a terahertz frequency band, the carrier bandwidth of a wireless signal can reach more than dozens of GHz. Because the frequency difference of different subcarriers in the bandwidth is large, when the base station adopts a beamforming mode to send a large-bandwidth signal, the beam direction of the signal can deviate on different subcarriers, so that the phenomenon of beam splitting occurs.

When downlink AoD positioning measurement is carried out in a terahertz frequency band, if the occupied bandwidth of PRS resources is large, each PRS resource corresponds to one downlink AoD range. Therefore, if the target UE still reports the PRS resource index and its RSRP value, the network side cannot determine the unique downlink AoD.

In order to solve the problem that the network side cannot determine the unique downlink AoD, the present application provides a method for measuring the downlink AoD in the terahertz frequency band, where the method may be implemented in a communication framework as shown in fig. 1, and for convenience of description, the present application refers to a terminal as UE, and refers to access point equipment and access network equipment as network equipment, and the method includes the following steps as shown in fig. 2:

step S200, a network device sends configuration information to UE, wherein the configuration information is used for configuring PRS resources sent by at least one TRP, and the PRS resources are resources sent under a terahertz frequency band;

the configuration information may be preset configuration information, and certainly in practical applications, the configuration information may also be configured through Control signaling, for example, RRC (Radio Resource Control) signaling and the like.

Step S201, the UE receives the configuration information, measures PRS resources sent by at least one TRP, and reports the index of the PRS resources sent by at least one TRP and the associated information of the PRS resources to the network equipment;

in an optional scheme, the association information includes: frequency position information and/or RSRP (Reference Signal Receiving Power) information corresponding to the indexes of the PRS resources.

The association information may specifically include: frequency location information or RSRP information corresponding to the index of the PRS resource, and of course, in practical application, the association information may further include: and frequency position information and RSRP information corresponding to the indexes of the PRS resources. For an accurate description of the information it contains in particular, reference may be made to the description of the following examples.

In an example one, the association information of the PRS resource specifically includes: the index of the sub-band corresponding to the RSRP maximum value in the sub-band occupied by the PRS resource and the RSRP maximum value;

in example two, the association information of the PRS resource specifically includes: and the subband index occupied by the PRS resource by the subband corresponding to the maximum RSRP value.

In example three, the association information of the PRS resource includes: an RSRP value of each of the sub-bands occupied by the PRS resource.

In an example four, the association information of the PRS resource specifically includes: and the RSRP value of a preset sub-band in the sub-band occupied by the PRS resource and the difference value of the RSRP value of other sub-bands relative to the preset sub-band.

In an example five, the association information of the PRS resources includes: n bits and/or RSRP values of the whole bandwidth occupied by the PRS resources, wherein each code point of the N bits is mapped to 2^ N continuous frequency ranges occupied by the PRS resources. Wherein "^" represents the power.

Each of the N-bit code points may be mapped to a midpoint frequency location of 2^ N consecutive frequency ranges occupied by PRS resources, but may be any other location, such as 1/4 frequency locations, for example, 3/4 frequency locations.

Step S202, the network equipment determines the downlink AoD according to the index of the PRS resource and the associated information of the PRS resource.

There may be various methods for implementing the step S202.

For example, in the above example one, the network device may determine, according to an index in the PRS resource occupancy subband, an AoD corresponding to the subband index from a mapping relationship between a preset subband index and the AoD.

The preset mapping relationship between the subband index and the AoD may be obtained by determining the AoD corresponding to each subband index in a laboratory in advance, traversing the indexes of all subbands corresponding to all PRS resources to obtain all aods, and configuring the mapping relationship in the network device after establishing the corresponding mapping relationship.

For example, in the second example, the network device may determine, according to a subband index occupied by the PRS resource and corresponding to the subband corresponding to the maximum RSRP value, the AoD corresponding to the subband index from a mapping relationship (which may be a preset mapping relationship, and a specific implementation manner may refer to the description of the first example).

For example, in the third example, the network device may extract a sub-band identifier corresponding to the maximum RSRP value in the sub-bands occupied by the PRS resource, and query the AoD corresponding to the sub-band identifier from a preset mapping relationship between the sub-band and the AoD according to the sub-band identifier.

For example, in the fourth example, the network device may determine, by using the RSRP value of the preset subband and the difference between the RSRP value of the other subbands and the RSRP value of the preset subband, the subband identifier corresponding to the maximum RSRP value, and then determine the AoD according to the subband identifier (see the description in the third example specifically, which is not repeated here).

For example, the predetermined subband may be subband 0, and if the corresponding RSRP value is RSRP 0, if there are 6 subbands in total, 5 differences between the RSRP values of the other 5 subbands and RSRP 0 are calculated, and if the 5 differences are negative values, RSRP 0 is determined as the maximum RSRP value, and the subband identifier is subband 0.

For example, in the fifth example, the network device may determine, from the code points in the N bits, a frequency range corresponding to the code point with the largest RSRP value, and determine, according to the frequency range, an AoD corresponding to the frequency range from a preset mapping relationship between a frequency and the AoD.

According to the technical scheme provided by the application, network equipment sends configuration information to UE, wherein the configuration information is used for configuring PRS resources sent by at least one TRP, and the PRS resources are resources sent under a terahertz frequency band; the UE receives the configuration information, measures the PRS resource sent by at least one TRP, and reports the index of the PRS resource sent by at least one TRP and the association information of the PRS resource to the network equipment; the network equipment determines the downlink AoD according to the indexes of the PRS resources and the associated information of the PRS resources, so that the determination of the AoD can be realized under the terahertz frequency band, the UE can be positioned through the AoD under the terahertz frequency band, and the positioning precision is improved.

additionally configuring at least one frequency domain sub-band occupied by each PRS resource to a target UE by a network side, reporting an index of the PRS resource sent by at least one TRP by the target UE, and reporting the index of the PRS resource occupied by the PRS resource in the sub-band occupied by the PRS resource:

the sub-band index with the maximum RSRP and the RSRP value of the sub-band thereof;

or RSRP values per subband;

or the RSRP value of the sub-band with the lowest index (i.e. the preset sub-band), and the differential RSRP values of other sub-bands relative to the sub-band with the lowest index;

in another optional scheme, when the index of the PRS resource sent by at least one TRP is reported by predefined or configured by a network side, the frequency domain position information is reported by using N bits;

wherein each code point (codepoint) of N bits is uniformly mapped into the bandwidth occupied by the PRS resource.

Step S303, the network side obtains the indexes, frequency positions and RSRP information of the PRS resources reported by the target UE to obtain the downlink AoD of the target UE and each reported TRP.
