For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

In the NR Rel-16 system, the newly defined positioning use reference signals include a downlink positioning reference signal PRS and an uplink sounding reference signal SRS for positioning. The PRS is mainly PRS supporting periodic transmission, and may support repeated transmission of PRS resources in one transmission period, but for repeated transmission of PRS resources, the number of repeated transmissions and a time interval between two adjacent transmissions need to be configured, and the time interval between two adjacent transmissions is in units of slots, where the time interval is N slots, and N is a natural number. In other words, current PRSs can only be transmitted once within a slot. Moreover, each PRS may occupy 2 or 4 or 6 or 12 consecutive symbols in a slot, and the starting symbol position may be any one of the 1 st to 13 th symbols in a slot.

Regarding the configuration of the uplink SRS for positioning, it may support periodic, semi-persistent, and aperiodic SRS transmission. Each SRS may occupy 1 or 2 or 4 or 8 or 12 symbols in succession in one slot, and the starting symbol position may be any one of the 1 st to 14 th symbols in one slot.

The accuracy of the existing positioning scheme can only reach 10m (meters) and the time delay can only reach 1s (seconds), however, in NR Rel-17 to be discussed, because of the scenes such as industrial internet of things and the like, the accuracy and the time delay of the positioning are required to be higher, for example, the accuracy is less than 1m (meters), and the time delay is less than 100ms or even 10ms.

The reference signal transmission method, the user equipment, the network equipment and the electronic equipment provided by the embodiment of the disclosure aim to solve the technical problems in the prior art.

The following describes in detail, with specific embodiments, a technical solution of an embodiment of the present disclosure and how the technical solution of the embodiment of the present disclosure solves the foregoing technical problems. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present disclosure will be described below with reference to the accompanying drawings.

One embodiment of the present disclosure provides a reference signal transmission method, which is performed by a user equipment UE, as shown in fig. 1, and includes:

step S110, receiving configuration information of a positioning purpose reference signal sent by a first network device; step S120, according to the configuration information, the first time of transmission of the reference signal for positioning use is performed with the second network device in one time slot, where the first time is an integer greater than 1.

In one possible implementation, the positioning-purpose reference signal is a reference signal that may be used to determine the spatial location of the terminal, e.g., positioning-purpose reference signals include, but are not limited to: a positioning reference signal PRS for positioning transmitted in a downlink direction is recorded as a downlink positioning reference signal; and a sounding reference signal SRS for positioning, which is sent in the uplink direction, is denoted as an uplink positioning reference signal. That is, the positioning reference signal may be a downlink positioning reference signal or an uplink positioning reference signal.

In one possible implementation, the first network device configures configuration information of the positioning usage reference signal for the user device, so that the user device performs transmission of the positioning usage reference signal with the second network device according to the configuration information. Correspondingly, the user equipment receives the configuration information of the positioning purpose reference signal sent by the first network equipment, and then the user equipment transmits the positioning purpose reference signal with the second network equipment according to the configuration information.

The first network device and the second network device may be the same or different. In an alternative embodiment, when the first network device is the same as the second network device, the above steps S110 and S120 may be expressed as: step S110, receiving configuration information of a positioning usage reference signal sent by a first network device (or a second network device), step S120, where the user device performs transmission of the positioning usage reference signal with the first network device (or the second network device) for a first time in a time slot according to the configuration information, where the first time is an integer greater than 1.

The configuration information of the positioning usage reference signal is configured based on micro time slots (mini-slots), for example, the positioning usage reference signal is configured to be transmitted multiple times in one time slot, that is, the transmission of the positioning usage reference signal is based on the transmission of the positioning usage reference signal of the micro time slot, that is, the user equipment performs the transmission of the positioning usage reference signal with the second network equipment according to the configuration information, that is, performs the transmission of the positioning usage reference signal with the second network equipment for a first time in one time slot, and the first time is an integer greater than 1.

According to the reference signal transmission method provided by the embodiment of the disclosure, the positioning purpose reference signal of the first time is transmitted in one time slot according to the configuration information of the positioning purpose reference signal, so that the positioning purpose reference signal can be transmitted for multiple times in one time slot, the transmission of the positioning purpose reference signal based on the micro time slot is realized, the positioning precision is improved, the positioning time delay is reduced, and the requirements of an NR system on the positioning technology are met.

The reference signal transmission method in the embodiment of the present disclosure is specifically described below:

in one possible implementation of the embodiments of the present disclosure, the first network device includes at least one of: the positioning management function entity LMF, the base station and the vehicle-mounted terminal equipment.

The network device may be an LMF (Location Management Function, location management function entity), a base station, or an in-vehicle terminal device, or of course, may be other network side devices, which is not limited by the embodiments of the present disclosure. In one example, the network device may also refer to different transmission and reception points of the same base station, or different antenna panels of the same base station. The types of base stations include various forms of macro base stations, micro base stations, relay stations, access points, and the like. Types of user equipment include cell phones, vehicle user terminals, tablet computers, laptops, personal digital assistants, mobile internet appliances, wearable devices, and the like. The types of the user equipment also comprise vehicle-mounted equipment terminals, internet of things equipment terminals, industrial internet of things equipment terminals and the like. In one example, in the in-vehicle networking communication, both the network device and the user device may be in-vehicle terminal devices.

In an alternative way, the first network device may be an LMF and/or a base station, and the second network device may be a base station or an in-vehicle terminal device.

When the first network device is an LMF and the second network device is a base station, the user equipment receives configuration information of the positioning use reference signal sent by the LMF, and then, the user equipment performs transmission of the positioning use reference signal of the first number with the base station in one time slot according to the configuration information.

When the first network device is a base station and the second network device is a base station, the user equipment receives configuration information of the positioning usage reference signal sent by the base station, and then, the user equipment performs first-time transmission of the positioning usage reference signal with the base station in one time slot according to the configuration information.

The first network device may be a base station where a serving cell is located, and the second network device may be a base station where a serving cell is located, or may be a base station where a neighbor cell is located. The second network device may also be a plurality of different cells, different transmission and reception points (Transmission Reception Point, TRP), or different network side antenna panels.

When the first network device is an LMF and the second network device is a vehicle-mounted terminal device, the user device receives configuration information of the positioning usage reference signal sent by the LMF, and then, the user device performs transmission of the positioning usage reference signal for the first time with the vehicle-mounted terminal device in one time slot according to the configuration information.

When the first network device is a base station and the second network device is a vehicle-mounted terminal device, the user device receives configuration information of the positioning purpose reference signal sent by the base station, and then, the user device performs transmission of the positioning purpose reference signal for the first time with the vehicle-mounted terminal device in one time slot according to the configuration information.

In one possible implementation manner of the embodiment of the present disclosure, the reference signal identifiers of the positioning usage reference signals transmitted in one time slot for the first time are all the same; alternatively, the reference signal identities of the first number of positioning use reference signals transmitted within one slot are different.

A first number of positioning use reference signals may be transmitted in one slot, such as M positioning use reference signals in one slot, M being an integer greater than 1.

In one aspect, the M positioning use reference signals transmitted in one slot may be repeated transmissions of the same positioning use reference signal, i.e. the reference signal identities of the positioning use reference signals transmitted each time are the same. If the value of M is 3, the downlink positioning reference signal transmitted for the first time is prs_1, and the downlink positioning reference signal transmitted for the second time is prs_1, and the downlink positioning reference signal transmitted for the third time is prs_1.

On the other hand, the reference signal identities of the M positioning use reference signals transmitted in one slot are different. In one case, the M positioning use reference signals transmitted in one slot include both X repeated transmissions of the same positioning use reference signal and Y transmissions of different positioning use reference signals, i.e. the reference signal identities of the positioning use reference signals of the X transmissions are the same, and the reference signal identities of the positioning use reference signals of the Y transmissions are different, where x+y=m. In another case, the reference signal identities of the M positioning reference signals transmitted in one slot are different, i.e. M different positioning reference signals are transmitted in one slot, such as the first transmission of the downlink positioning reference signal prs_1, the second transmission of the downlink positioning reference signal prs_2, and so on, the mth transmission of the downlink positioning reference signal prs_m.

In one possible implementation of the embodiment of the disclosure, the configuration information includes first configuration information, where the first configuration information is used to indicate that a transmission period of the positioning usage reference signal is a first number of symbols, and the first number is a positive integer.

In an alternative manner, the first configuration information may be LTE positioning protocol LPP information, radio resource control RRC information, LPP information, and RRC information. For example, the first network device configures a transmission period of the positioning usage reference signal through LPP signaling and/or RRC signaling, and the transmission period may be less than one slot, for example, the transmission period may be N symbols. In other words, the first network device may indicate to the user equipment that the transmission period of the positioning usage reference signal is a first number of symbols, such as the transmission period is N symbols, through the LPP information and/or the RRC information.

The first configuration information may indicate, in addition to the first number of symbols in the transmission period of the positioning use reference signal, a starting symbol position of the positioning use reference signal transmitted for the first time and the number of symbols occupied by the positioning use reference signal transmitted each time. The number of symbols occupied by the reference signal for positioning use per transmission may be 1 symbol, 2 symbols, 4 symbols, 7 symbols, etc. Since the transmission period of the positioning use reference signal is a first number of symbols, when the first number is less than 14, it is possible to implement repeating transmission of the positioning use reference signal multiple times in one slot.

For the downlink positioning reference signals PRS, the number of symbols occupied by PRS may be 1 or 2 or 4 or 6 or 12. In the first case, for PRS occupying 1 or 2 or 4 or 6 symbols, the transmission period may be half slot, and when one slot contains 12 symbols, the half slot is 6 symbols, i.e. the transmission period is 6 symbols, and then the number of transmissions in one slot is 2; when a slot contains 14 symbols, half of the slot is 7 symbols, i.e. the transmission period is 7 symbols, and then the number of transmissions in a slot is 2.

In the second case, for PRS occupying 2 symbols, when the transmission period is 2 symbols, PRS may be transmitted 6 times (where one slot includes 12 symbols) or 7 times (where one slot includes 14 symbols) within one slot, i.e., the number of transmissions within one slot is 6 times or 7 times; when the transmission period is 4 symbols, 3 PRSs can be transmitted in one time slot, i.e. the number of transmissions in one time slot is 3; when the transmission period is 6 symbols, PRS may be transmitted 2 times in one slot, i.e., the number of transmissions in one slot is 2.

In the third case, for PRS occupying 4 symbols, when the transmission period is 4 symbols, 3 PRS may be transmitted in one slot, i.e., the number of transmissions in one slot is 3; when the transmission period is 6 symbols, PRS may be transmitted 2 times in one slot, i.e., the number of transmissions in one slot is 2.

For the uplink positioning reference signal SRS, the number of symbols occupied by the SRS may be 1 or 2 or 4 or 8 or 12. In the first case, for SRS occupying 2 symbols, when the transmission period is 2 symbols, SRS may be transmitted 6 times (when one slot is 12 symbols) or 7 times (when one slot is 14 symbols) in one slot, that is, the number of transmissions in one slot is 6 times or 7 times; when the transmission period is half a slot (i.e., 6 symbols or 7 symbols), 2 SRS may be transmitted in one slot, i.e., the number of transmissions in one slot is 2; when the transmission period is 4 symbols, 3 SRS may be transmitted in one slot, i.e., the number of transmissions in one slot is 3.

In the second case, for SRS occupying 1 symbol, when the transmission period is 1 symbol, SRS may be transmitted 12 times (when one slot is 12 symbols) or 14 times (when one slot is 14 symbols) in one slot, that is, the number of transmissions in one slot is 12 or 14 times; when the transmission period is 2 symbols, 6 (when one slot is 12 symbols) SRS or 7 (when one slot is 14 symbols) SRS may be transmitted in one slot, that is, the number of transmissions in one slot is 6 or 7; when the transmission period is 3 symbols, 4 SRS can be transmitted in one time slot, that is, the number of transmissions in one time slot is 4; when the transmission period is 4 symbols, 3 SRS may be transmitted in one slot, i.e., the number of transmissions in one slot is 3.

In one possible implementation of the embodiment of the disclosure, the configuration information includes first configuration information, where the first configuration information is used to indicate that a transmission period of the positioning usage reference signal is a second number of slots, and the second number is a positive integer.

In an alternative manner, the first configuration information may be LPP information, or RRC information, or LPP information and RRC information. For example, the network device configures the transmission period of the positioning usage reference signal through LPP signaling and/or RRC signaling, and the transmission period may be on a slot level, for example, the transmission period may be 1 slot, 2 slots, 4 slots, etc. In other words, the first network device may indicate to the user equipment that the transmission period of the positioning usage reference signal is the second number of time slots, such as the transmission period is 1 time slot, 2 time slots, 4 time slots, etc., through the LPP information and/or the RRC information.

The first configuration information may indicate, in addition to the transmission period of the positioning reference signal being the second number of timeslots, the number of repeated transmissions of the positioning reference signal and a time interval between two adjacent transmissions, where the number of repeated transmissions of the positioning reference signal may be a repetition factor of the positioning reference signal resource and the time interval between two adjacent transmissions may be a time interval between two adjacent repeated positioning reference signal resources. The time interval is a third number of symbols, the third number being a positive integer. For example, the first configuration information indicates that the time interval between two adjacent transmissions of the positioning use reference signal is 0 symbols, 1 symbol, 2 symbols, 3 symbols, 4 symbols, 5 symbols, 6 symbols, 7 symbols, etc. The time interval refers to the interval between the last symbol occupied by the first transmission and the first symbol occupied by the second transmission.

In addition, the first configuration information may further indicate a starting symbol position of the reference signal for positioning use transmitted for the first time, and the number of symbols occupied by the reference signal for positioning use transmitted each time. For example, the initial symbol position of the first transmission positioning reference signal may be the 1 st symbol, the 3 rd symbol, the 4 th symbol, etc. of one slot, and for example, the number of symbols occupied by the positioning reference signal transmitted each time is 1 symbol, 2 symbols, 4 symbols, 7 symbols, etc.

Typically, the time interval between two adjacent transmissions of the positioning usage reference signal configured by the first network device through LPP signaling and/or RRC signaling is smaller than one slot, such as the time interval of 3 symbols, 6 symbols, 7 symbols, etc., so that the positioning usage reference signal can be transmitted multiple times in one slot.

In one embodiment, the symbol interval value is applicable within one slot and is not applicable between slots. For example, for PRS occupying 4 symbols, if the time interval between two adjacent transmissions of PRS is 0 symbols, for a slot including 12 symbols, three PRS may be transmitted in one slot, e.g., symbols occupied by three transmissions in the first slot are first transmission occupied symbols #0 to #3, second transmission occupied symbols #4 to #7, and third transmission occupied symbols #8 to #11, respectively. Then the transmission in each subsequent slot is the first transmission occupied symbols #0 to #3, the second transmission occupied symbols #4 to #7, and the third transmission occupied symbols #8 to #11.

In another embodiment, the symbol interval value is applied within one slot, as well as between slots. For example, for PRS occupying 4 symbols, if the time interval between two adjacent transmissions of PRS is 0 symbols, for a slot including 12 symbols, three PRS may be transmitted in one slot, for example, symbols occupied by three transmissions in the first slot #0 are first transmission occupied slot #0 to #3, second transmission occupied slot #0 symbols #4 to #7, and third transmission occupied slot #0 symbols #8 to #11, respectively. Then the fourth transmission occupies the symbols #12, #13, and #0 and #1 of slot #0, the second transmission occupies the symbols #2 to #5 of slot #1, the third transmission occupies the symbols #6 to #19, … … of slot #1, and so on.

In one case, for PRSs occupying 2 symbols, if the time interval between two adjacent transmissions of PRSs is 6 symbols, for one slot including 12 symbols, two PRSs may be transmitted within one slot; if the time interval between two adjacent transmissions of PRS is 7 symbols, for one slot comprising 14 symbols, two PRSs may be transmitted within one slot.

In yet another case, for PRSs occupying 4 symbols, if the time interval between two adjacent transmissions of PRSs is 0 symbols, three PRSs may be transmitted within one slot for one slot including 12 symbols; if the time interval between two adjacent transmissions of PRS is 2 symbols, for one slot comprising 12 symbols, two PRSs may be transmitted in one slot.

In yet another case, for PRSs occupying 6 symbols, if the time interval between two adjacent transmissions of PRSs is 0 symbols, two PRSs may be transmitted within one slot for one slot including 12 symbols.

The determining process of the time interval between two adjacent transmissions and the number of transmissions in one slot is similar to the determining process of the time interval between two transmissions of the PRS and the number of transmissions in one slot for the SRS occupying 1 or 2 or 4 or 8 or 12 symbols, and is not described herein.

In a possible implementation manner of the embodiment of the present disclosure, the configuration information further includes second configuration information, where the second configuration information is used to indicate a time interval between two adjacent transmissions of the positioning usage reference signal, and the time interval is a fourth number of symbols, and the fourth number is a positive integer.

The configuration information of the positioning usage reference signal configured by the first network device for the user device includes, in addition to the first configuration information for indicating that the transmission period of the positioning usage reference signal is the second number of time slots, second configuration information for indicating a time interval between two adjacent transmissions of the positioning usage reference signal, that is, the network device indicates that the transmission period of the positioning usage reference signal is the second number of time slots through the first configuration information, and indicates the time interval between two adjacent transmissions of the positioning usage reference signal through the second configuration information. Likewise, the time interval between two adjacent transmissions of the positioning-purpose reference signal may also be the time interval between two adjacent repetitions of the positioning-purpose reference signal resource, the time interval being a fourth number of symbols. The fourth number may be the same as or different from the third number.

In one possible implementation of the embodiment of the disclosure, the first configuration information is further used for indicating a set of time intervals between two adjacent transmissions of the positioning usage reference signal, and the configuration information further includes second configuration information, where the second configuration information is used for indicating one time interval in the set of time intervals.

The second configuration information is media access control MAC information or downlink control indication DCI information.

The first network device indicates, in addition to the transmission period of the positioning use reference signal being the second number of time slots by the first configuration information, a set of time intervals between two adjacent transmissions of the positioning use reference signal by the first configuration information, i.e. a plurality of available time intervals are given by the first configuration information. When a plurality of available time intervals (i.e., a set of time intervals) between two adjacent transmissions of the positioning use reference signal are indicated by the first configuration information, one time interval of the set of time intervals may be indicated as a target time interval by the second configuration information, so that the user equipment transmits the positioning use reference signal with the second network equipment a plurality of times within one transmission period according to the target time interval.

In one example, if the set of time intervals between two adjacent transmissions of the positioning usage reference signal indicated by the first configuration information includes 4 time intervals, i.e. the first configuration information gives 4 available time intervals, respectively T1, T2, T3 and T4, at this time, one time interval in the set of time intervals may be indicated as a target time interval by the second configuration information, e.g. the second configuration information indicates the time interval T1 as a target time interval, and the user equipment may transmit the positioning usage reference signal with the second network equipment multiple times in one transmission period according to the time interval T1, and, for example, the second configuration information indicates the time interval T3 as a target time interval, and the user equipment may transmit the positioning usage reference signal with the second network equipment multiple times in one transmission period according to the time interval T3.

In an alternative manner, the second configuration information may be media access control MAC information, or downlink control indication DCI information, that is, the network device may activate one time interval in the time interval set through MAC signaling as a target time interval, or may indicate one time interval in the time interval set through DCI signaling as a target time interval.

In an alternative, the time intervals in the set of time intervals indicated by the first configuration information may be symbol level, i.e. the time intervals in the set of time intervals comprise a fifth number of symbols, the fifth number being a positive integer, if there are 2 symbols for the time interval, if there are 4 symbols for the time interval, if there are 7 symbols for the time interval, if there are 14 symbols for the time interval, if there are 28 symbols for the time interval, etc.

In an alternative, the time intervals in the set of time intervals indicated by the first configuration information may be of a time slot level, the time intervals in the set of time intervals comprising a sixth number of time slots, e.g. 1/4 time slots, 1/2 time slots, 1 time slot, 2 time slots, 4 time slots, etc.

In an alternative, the time intervals in the set of time intervals indicated by the first configuration information are at the slot level, at the symbol level, at the time interval of 2 symbols, at the time interval of 7 symbols, at the time interval of 1 slot, at the time interval of 2 slots, at the time interval of 4 slots, etc.

In one possible implementation of the embodiment of the present disclosure, the first configuration information is further used to indicate a set of time intervals between two adjacent transmissions of the positioning usage reference signal, the configuration information further includes second configuration information, and the second configuration information includes MAC information and DCI information, where the MAC information is used to indicate a set of candidate time intervals in the set of time intervals, and the DCI information is used to indicate one time interval in the set of candidate time intervals.

When the first network device indicates a plurality of available time intervals (i.e., a set of time intervals) between two adjacent transmissions of the positioning use reference signal through the first configuration information, one time interval in the set of time intervals may be indicated as a target time interval through the second configuration information, so that the user device transmits the positioning use reference signal with the second network device multiple times within one transmission period according to the target time interval. Wherein the second configuration information includes MAC information and DCI information.

When one of the time interval sets is indicated as the target time interval by the second configuration information, the candidate time interval set of the time interval sets may be indicated by the MAC information, and one of the candidate time interval sets may be indicated as the target time interval by the DCI information.

In one example, if the set of time intervals between two adjacent transmissions of the positioning usage reference signal indicated by the first configuration information includes 4 time intervals, i.e. the first configuration information gives 4 available time intervals, i.e. T1, T2, T3 and T4, respectively, then the set of candidate time intervals in the set of time intervals, e.g. the set of candidate time intervals is T1, T2 and T3, e.g. the set of candidate time intervals is T1, T2 and T4, e.g. the set of candidate time intervals is T2 and T3, respectively, may be indicated by the MAC information.

In one example, taking the candidate time interval sets as T1, T2 and T3 as an example, one time interval in the candidate time interval sets (i.e. T1, T2 and T3) may be indicated as a target time interval by DCI information, for example, the time interval T1 is indicated as a target time interval, and accordingly, the ue transmits the positioning usage reference signal with the second network device multiple times in one transmission period according to the time interval T1; for another example, the indication time interval T3 is a target time interval, and accordingly, the ue transmits the positioning usage reference signal with the second network device multiple times in a transmission period according to the time interval T3.

Based on this, in the process that the user equipment transmits the first number of positioning use reference signals with the second network equipment in one time slot according to the configuration information, the user equipment may send the first number of uplink sounding reference signals SRS for positioning use to the second network equipment in one time slot according to the configuration information, for example, the user equipment sends the M number of uplink sounding reference signals SRS for positioning use to the network equipment in one time slot according to the configuration information, where M is an integer greater than 1; or the ue may receive, according to the configuration information, the first number of downlink positioning reference signals PRS sent by the second network device in one timeslot, for example, M downlink positioning reference signals PRS sent by the network device in one timeslot.

In an alternative manner, after receiving M downlink positioning reference signals PRS sent by the second network device in one timeslot, the user device may perform corresponding measurement according to the M downlink positioning reference signals PRS, and after completing the measurement, may feed back a measurement result to the network device.
