Before describing the communication method of the present application, the concepts related to the present application will be described:

1. positioning reference signal (Positioning REFERENCE SIGNAL, PRS) resource

And the terminal equipment performs timing measurement of the downlink reference signals on the PRS of each base station and sends the measurement result to the position server for positioning of the terminal equipment.

The PRS bearing resources are understood as PRS resources. As shown in fig. 1b, a PRS configuration schematic diagram provided in an embodiment of the present application, where a parameter structure of PRS configuration includes positioning frequency layer (positioning frequency layer) - > transmission and reception node identifier (Transmission Reception Point, TRP) ID- > PRS resource set- > PRS resource, that is, one positioning frequency layer may deploy multiple TRPs, one TRP may correspond to multiple PRS resource sets, and one PRS resource set may include multiple PRS resources.

Some parameters are configured for the frequency layer, i.e. the parameter scope is all PRS resources contained in this frequency layer. Parameters configured for the frequency layer may include: the frequency domain resource reference position of the PRS, the subcarrier spacing of the PRS, the CP type of the PRS, the resource pattern of the PRS, the starting RB of the PRS, the bandwidth of the PRS, etc.

Some parameters are configured for a set of PRS resources, with the scope being all PRS resources within the set of PRS resources. The parameters configured for the PRS resource set may include: the period of PRS resources (period is T as shown in fig. 1 c), the starting slot of the PRS resource set, the repetition factor of PRS resources (repetition factor is 2 as shown in fig. 1c, i.e. the number of repetitions of PRS resources in the same period), the repetition interval between PRS resources (i.e. the interval between two PRS resources repeated in the same period), and the muting pattern of PRS transmissions, etc.

Some parameters are configured for PRS resources, the scope of action being the PRS resources. The parameters for PRS resource configuration may include: the PRS resource occupies the starting RE position of the first symbol, and the RE position interval relative to the first symbol, the interval (in slots) of the PRS relative to the first slot of the PRS resource set, the PRS starting symbol position, and the number of symbols occupied.

2. PRS resource repetition

PRS resource repetition may be understood as a repetition of PRS resources with the same PRS resource identity, where the size of time domain resources occupied by the repeated PRS resources in the time domain and the size of frequency domain resources occupied in the frequency domain are the same, but repeated in the time domain. In some embodiments, repetition of a PRS resource may be understood as a repetition within one PRS resource period, as shown in fig. 1c, where resource 1 is repeated twice at a repetition interval within the same period T with a repetition factor of 2. It will be appreciated that one PRS resource in the PRS set is taken as an example in fig. 1 c.

In some scenarios, PRS resource repetition may also be understood as, or replaced with, repetition of PRS.

In the field, the initial RB of PRS and the bandwidth of PRS are generally configured for the frequency layer, that is, all PRS resources in the frequency layer are the same initial RB and the occupied PRS bandwidth, and in the scenario that the terminal device limits the bandwidth, the channel bandwidth is smaller, which causes a problem of reduced measurement accuracy. According to the signal measurement method provided by the application, the PRS can be transmitted in a frequency hopping mode, or the frequency domain positions of PRS resources occupied by the PRS are different, so that the bandwidth of a channel is indirectly widened, and the positioning precision of terminal equipment is improved.

As shown in fig. 2, a flow chart of an embodiment of a signal measurement method provided by the present application, as shown in fig. 2, may include, but is not limited to, the following steps:

101, the network device sends resource configuration information of the positioning reference signal to the terminal device. Correspondingly, the terminal equipment receives the resource configuration information of the positioning reference signal.

102, The terminal equipment measures the positioning reference signal according to the resource allocation information of the positioning reference signal.

In a first implementation, the resource configuration information is used to configure a frequency hopping pattern of the positioning reference signal.

Wherein the frequency hopping pattern is determined by at least one of the following parameters:

1. the frequency hopping times of the positioning reference signal; as shown in fig. 3a, taking the positioning reference signal as PRS as an example, the number of hops of PRS is 3.

2. Positioning a frequency domain starting position of the first frequency hopping of the reference signal; in some scenarios, the frequency domain starting position of the first frequency hopping may be a frequency domain starting position of a positioning reference signal resource configured by the network device. As shown in fig. 3a, taking the positioning reference signal as an example of PRS, the frequency domain starting position of the first frequency hopping is the frequency domain starting position of the resource where the first PRS is transmitted.

3. A frequency hopping bandwidth of the positioning reference signal; as shown in fig. 3a, the frequency hopping bandwidth of the positioning reference signal may be understood as the frequency domain size of the Resource where the positioning reference signal is transmitted at one time, for example, the frequency hopping bandwidth may be 50 (Resource Block, RB).

4. Positioning the frequency domain interval of the reference signal between two adjacent frequency hopping; the frequency domain interval between two adjacent frequency hops may be the difference between the frequency domain starting positions or the frequency domain ending positions of the resources corresponding to the two adjacent frequency hops. The measurement unit of the frequency domain interval may be RB or MHz, which is not limited by the present application. As shown in fig. 3a, the frequency domain interval is the difference between the frequency domain starting positions of the resources corresponding to the adjacent frequency hopping, for example, the frequency domain interval may be 40 RBs.

5. Positioning a time interval between two adjacent frequency hopping of the reference signal; the time domain interval between two adjacent frequency hopping can be the difference between the time domain starting positions of the resources corresponding to the two adjacent frequency hopping or the difference between the time domain ending positions. As shown in fig. 3a, the time interval is the difference between the time domain starting positions of the resources corresponding to the adjacent two frequency hops. Optionally, in some embodiments, the positioning reference signal includes N repetitions of the positioning reference signal between two adjacent hops, where N is an integer greater than or equal to 1, and a repetition interval of the N repetitions may be configured by the network device. As shown in fig. 3b, two repetitions of PRS are included between two adjacent hops. The value of N may be configured by the network device, for example, the value of N may be a repetition factor of the network device configuration. It is understood that the unit of measure of the time interval may be a time slot, a millisecond, a repetition number of the positioning reference signal, etc., and the present application is not limited thereto.

6. The number of repetitions of the positioning reference signal may be, for example, the product of the number of hops and N. As shown in fig. 3b, the number of repetitions is 6.

The frequency hopping pattern can be determined by at least one of the above parameters 1-6, as shown in fig. 3a, which is an example of a frequency hopping pattern. Illustratively, the frequency hopping pattern may be repeated M times, M being an integer greater than or equal to 1. It will be appreciated that the starting time-domain positions of the M frequency hopping patterns are different, as shown in fig. 3b, and that fig. 3b can be understood to include two repetitions of the frequency hopping pattern, i.e. m=2. For example, the time interval of two adjacent hopping patterns in the time domain may be a repetition interval of the network device configuration.

In some embodiments, the network device may mute one or more of the M repeated frequency hopping patterns, where mute may be understood as that the network device does not transmit the positioning reference signal on the resource corresponding to the frequency hopping pattern, and the terminal device does not measure the positioning reference signal on the resource corresponding to the frequency hopping pattern.

For example, the network device may send indication information to the terminal device, where the indication information may include M bits, one bit corresponding to one of M repeated frequency hopping patterns, and the bit is used to indicate whether the corresponding frequency hopping pattern is muted. As shown in fig. 3b, the hopping pattern is repeated twice, so that the indication information includes two bits, the first bit corresponding to the shaded hopping pattern and the second bit corresponding to the unshaded hopping pattern. If the bit value 0 indicates that the hopping pattern is muted, if the indication information includes 01, the network device is instructed not to transmit the positioning reference signal on the resource corresponding to the hopping pattern that is not shaded, and only transmit the positioning reference signal on the resource corresponding to the hopping pattern that is not shaded, and therefore, the terminal device also measures the positioning reference signal only on the resource corresponding to the hopping pattern that is not shaded.

In some embodiments, the above-mentioned frequency hopping pattern may be configured for a frequency layer by the network device, that is, the frequency hopping pattern is applicable to the positioning reference signal resources of the frequency layer, in other words, all positioning reference signal resources of the frequency layer are repeated with the frequency hopping pattern. It is to be appreciated that the frequency hopping pattern can also be configured for a set of positioning reference signal resources by the network device, i.e., the frequency hopping pattern applies to positioning reference signal resources in the set of positioning reference signal resources, in other words, all positioning reference signal resources in the set of positioning reference signal resources are repeated in the frequency hopping pattern. It is to be appreciated that the frequency hopping pattern can also be configured by the network device for positioning reference signal resources, in other words, the positioning reference signal resources are repeated in the frequency hopping pattern.

It should be noted that, the repetition of the positioning reference signal resource in the frequency hopping pattern is understood that the repetition of the positioning reference signal resource in the frequency hopping pattern is performed within a period, and the repetition number is M, and the period may be the period of the positioning reference signal resource. As shown in fig. 3c, T is a period, and resource 1 is a positioning reference signal resource, and the resource 1 is repeated twice in the period T.

The terminal equipment can periodically measure the positioning reference signal with a certain measurement gap, and the measurement gap patterns of the terminal equipment can be various because the positioning reference signal is transmitted in a frequency hopping manner. For example, one measurement gap pattern may be determined by a measurement start time and a measurement period, and different measurement gap patterns may refer to different measurement start times and/or measurement periods. As shown in fig. 3b, the terminal device may measure the positioning reference signal carried on the resource coated with the shadow portion, or may measure the positioning reference signal carried on the resource not coated with the shadow portion, where the measurement gap patterns corresponding to the two measurement manners are different. In the positioning reference signal frequency hopping transmission, the network device may configure the number of measurement gap patterns and/or the identification information of the measurement gap patterns associated with one frequency layer or one positioning reference signal resource set, so that the terminal device is convenient to determine multiple measurement gap patterns, and the terminal device may use at least one measurement gap pattern in the multiple measurement gap patterns to perform positioning reference signal measurement. In some implementations, the number of measurement gap patterns associated with one frequency layer or one set of positioning reference signal resources is the number of hops of the positioning reference signal.

In some embodiments, the terminal device may also determine a measurement delay according to the frequency hopping number of the positioning reference signal, and in some scenarios, the measurement delay may also be referred to as a measurement period, and the terminal device needs to complete measurement of the positioning reference signal within the measurement delay. The measurement delay may be, for example, a time required to limit the terminal device to complete the positioning reference signal measurement within one period. The following formula shows an acquisition mode for measuring the time delay T _RSTD,i:

Wherein K is the frequency hopping times, CSSF _PRS,i is the scaling factor of the carrier level of the frequency layer i based on PRS positioning measurement, ceil (K _p,PRS,i) is the scaling factor of the frequency layer i, N _RxBeam,i is the receiving beam polling factor of the terminal equipment, For the number of PRS resources of the frequency layer i in one slot, N' is the PRS measurement time for which L _{available_PRS,i} is the frequency i valid, N is the time occupied by the PRS symbol, N _sample is the number of measurement samples measured once, T _effect,i is the period for PRS measurement of the frequency layer i, and T _last,i is the duration of the last measurement sample.

In a first implementation manner, the positioning reference signal is subjected to frequency hopping transmission by configuring the frequency hopping pattern of the positioning reference signal, and in a scene of limited bandwidth of the terminal equipment, the terminal equipment can realize the measurement of the positioning reference signal under a larger bandwidth by frequency hopping for a plurality of times, so that the positioning precision of the terminal equipment is improved.

In a second implementation, the resource configuration information is used to configure frequency domain positions of a plurality of positioning reference signal resource sets of the positioning reference signals or to configure frequency domain positions of a plurality of positioning reference signal resources of the positioning reference signals.

In one possible design, the network device may configure frequency domain locations for multiple sets of positioning reference signal resources of the positioning reference signal, respectively. The frequency domain positions configured by the network device for different positioning reference signal resource sets may be the same or different, and the application is not limited. For example, the network device configures the frequency domain position 1 for the positioning reference signal resource set 1, configures the frequency domain position 2 for the positioning reference signal resource set 2, configures the frequency domain position 3 for the positioning reference signal resource set 3, and the frequency domain position 1 may be the same as the frequency domain position 2 and different from the frequency domain position 3, and it is understood that the frequency domain position 1, the frequency domain position 2, and the frequency domain position 3 may also be different from each other. The frequency domain location may include a frequency domain start location and/or a bandwidth. For example, the bandwidths of the respective sets of positioning reference signal resources may be the same, and the frequency domain starting positions of the respective sets of positioning reference signal resources may be different. As shown in fig. 5, the frequency domain starting positions of the reference signal resource set 1, the positioning reference signal resource set 2 and the positioning reference signal resource set 3 are respectively configured, and the 3 frequency domain starting positions are different.

The terminal equipment measures the positioning reference signals carried on the positioning reference signal resources of the positioning reference signal resource sets, and the frequency domain positions of the positioning reference signal resource sets are different, so that the channel bandwidth of the terminal equipment can be indirectly increased, and the positioning accuracy of the terminal equipment is improved.

In another possible design, the network device may also configure the frequency domain locations for each of the positioning reference signal resources in the same set of positioning reference signal resources, respectively. The frequency domain positions of the network devices configured for different positioning reference signal resources in the same positioning reference signal resource set may be the same or different, and the application is not limited.
