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

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

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

The embodiment of the disclosure provides a reference signal transmission method, user equipment, network equipment and electronic equipment, and aims to solve the above technical problems in the prior art.

The following describes in detail the technical solutions of the embodiments of the present disclosure and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present disclosure will be described below with reference to the accompanying drawings.

An embodiment of the present disclosure provides a reference signal transmission method, which is performed by a user equipment UE, and as shown in fig. 1, the method 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, performing a first number of transmissions of the positioning purpose reference signal with the second network device in a time slot, where the first number is an integer greater than 1.

In one possible implementation, the positioning-purpose reference signals are reference signals that may be used to determine the spatial position of the terminal, for example, the positioning-purpose reference signals include, but are not limited to: positioning reference signals PRS which are sent in a downlink direction and are used for positioning are recorded as downlink positioning reference signals; and a Sounding Reference Signal (SRS) for positioning transmitted in the uplink direction, and is referred to 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 a positioning purpose reference signal for the user equipment, so that the user equipment performs transmission of the positioning purpose reference signal with the second network device according to the configuration information. Correspondingly, the user equipment receives the configuration information of the positioning reference signal sent by the first network equipment, and then, the user equipment transmits the positioning 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 respectively expressed as: step S110, receiving configuration information of a positioning purpose reference signal sent by a first network device (or a second network device), and step S120, the user equipment performs a first number of transmissions of the positioning purpose reference signal with the first network device (or the second network device) in a time slot according to the configuration information, where the first number is an integer greater than 1.

The configuration information of the positioning-purpose reference signal is configured based on a micro slot (mini-slot), for example, the positioning-purpose reference signal may be configured to be transmitted multiple times in one slot, that is, the transmission of the positioning-purpose reference signal is based on the transmission of the positioning-purpose reference signal of the micro slot, that is, the user equipment performs the transmission of the positioning-purpose reference signal with the second network device according to the configuration information, which is to perform the transmission of the positioning-purpose reference signal with the second network device for a first number of times in one slot, where the first number of times 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 is transmitted for the first time 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, and the positioning purpose reference signal based on the micro time slot is transmitted, thereby improving the positioning precision, reducing the positioning time delay, and meeting the requirement of an NR system on the positioning technology.

The following specifically introduces a reference signal transmission method according to an embodiment of the present disclosure:

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

The network device may be an LMF (Location Management Function), a base station, a vehicle-mounted terminal device, or other network-side devices, which is not limited in the embodiments of the present disclosure. In one example, the network devices may also refer to different transmit and receive points of the same base station, or different antenna panels of the same base station. 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, laptop computers, personal digital assistants, mobile web appliances, wearable devices, and the like. The types of the user equipment also comprise a vehicle-mounted equipment terminal, an Internet of things equipment terminal, an industrial Internet of things equipment terminal and the like. In one example, in vehicle networking communications, the network device and the user device may both be in-vehicle terminal devices.

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

When the first network device is an LMF and the second network device is a base station, it is equivalent to that the user equipment receives the configuration information of the positioning purpose reference signal sent by the LMF, and then the user equipment performs the first number of transmissions of the positioning purpose reference signal 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, it is equivalent to that the user equipment receives the configuration information of the positioning reference signal sent by the base station, and then the user equipment performs the first transmission of the positioning 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 the 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 Reception Points (TRPs), 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, it is equivalent to that the user equipment receives configuration information of the positioning purpose reference signal sent by the LMF, and then the user equipment performs a first number of transmissions of the positioning purpose reference signal 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, it is equivalent to that the user device receives the configuration information of the positioning purpose reference signal sent by the base station, and then the user device performs the first number of times of transmission of the positioning purpose reference signal with the vehicle-mounted terminal device in one time slot according to the configuration information.

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

A first number of positioning-purpose reference signals may be transmitted in a slot, such as M times of positioning-purpose reference signals in a slot, where M is an integer greater than 1.

In one aspect, the M positioning-use reference signals transmitted in one time slot may be repeated transmissions of the same positioning-use reference signal, i.e., the reference signal identifier of each positioning-use reference signal transmitted is the same. If the value of M is 3, the downlink positioning reference signal transmitted for the first time is PRS _1, the downlink positioning reference signal transmitted for the second time is also PRS _1, and the downlink positioning reference signal transmitted for the third time is also PRS _ 1.

On the other hand, the reference signal identifications 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 time slot include both X times of repeated transmission of the same positioning-use reference signal and Y times of transmission of different positioning-use reference signals, that is, the reference signal identifiers of the positioning-use reference signals transmitted X times are the same, and the reference signal identifiers of the positioning-use reference signals transmitted Y times are different from each other, where X + Y is M. In another case, the reference signal identities of M positioning-purpose reference signals transmitted in one slot are different, that is, M different positioning-purpose reference signals are transmitted in one slot, for example, a first time is a downlink positioning reference signal PRS _1, a second time is a downlink positioning reference signal PRS _2, and so on, and an mth time is a downlink positioning reference signal PRS _ M.

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

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

The first configuration information may indicate, in addition to indicating that a transmission period of the positioning-purpose reference signal is a first number of symbols, a starting symbol position at which the positioning-purpose reference signal is transmitted for the first time, and a number of symbols occupied by each transmission of the positioning-purpose reference signal. The number of symbols occupied by the positioning-purpose reference signal per transmission may be 1 symbol, 2 symbols, 4 symbols, 7 symbols, or the like. Since the transmission period of the positioning reference signal is the first number of symbols, when the first number is less than 14, the positioning reference signal can be repeatedly transmitted in one slot for multiple times.

For downlink positioning reference signals PRS, the number of symbols occupied by the 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 a slot, and when a slot contains 12 symbols, half a slot is 6 symbols, that is, the transmission period is 6 symbols, then the number of transmissions in a 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 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 (when a slot includes 12 symbols) or 7 times (when a slot includes 14 symbols) within a slot, i.e., the number of transmissions within a slot is 6 times or 7 times; when the transmission period is 4 symbols, 3 PRS (pseudo random access channels) can be transmitted in one slot, that is, the number of transmissions in one slot is 3; when the transmission period is 6 symbols, 2 PRS (primary standard symbols) can be transmitted in one slot, that is, 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 times of PRS can be transmitted in one slot, that is, the number of transmissions in one slot is 3; when the transmission period is 6 symbols, 2 PRS (primary standard symbols) can be transmitted in one slot, that is, 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 an SRS occupying 2 symbols, when a transmission period is 2 symbols, 6 times (when one slot is 12 symbols) or 7 times (when one slot is 14 symbols) of the 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 a half slot (i.e. 6 symbols or 7 symbols), the SRS may be transmitted 2 times in one slot, that is, the number of transmissions in one slot is 2 times; when the transmission period is 4 symbols, 3 SRS transmissions may be performed in one slot, that is, the number of SRS transmissions in one slot is 3.

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

In a possible implementation manner of the embodiment of the present disclosure, the configuration information includes first configuration information, where the first configuration information is used to indicate that a transmission cycle of the reference signal for positioning purpose is a second number of slots, and the second number is a positive integer.

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

The first configuration information may indicate, in addition to the transmission cycle of the positioning reference signal being the second number of time slots, the number of times of repeated transmission of the positioning reference signal and a time interval between two adjacent transmissions, where the number of times of repeated transmission of the positioning reference signal may also be a repetition factor of the positioning reference signal resource, and the time interval between two adjacent transmissions may also 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-purpose reference signal is 0 symbol, 1 symbol, 2 symbols, 3 symbols, 4 symbols, 5 symbols, 6 symbols, and 7 symbols. 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 at which the positioning-purpose reference signal is transmitted for the first time and the number of symbols occupied by the positioning-purpose reference signal transmitted each time. For example, the starting symbol position of the first transmission of the positioning reference signal may be the 1 st symbol, the 3 rd symbol, the 4 th symbol, and the like of a slot, and for example, the number of symbols occupied by each transmission of the positioning reference signal is 1 symbol, 2 symbols, 4 symbols, 7 symbols, and the like.

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

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

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

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

Likewise, the time interval between two adjacent transmissions of the positioning purpose reference signal may also be a 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 here may be the same as or different from the third number.

In a possible implementation manner 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-purpose reference signal, and the configuration information further includes second configuration information, where the second configuration information is used to indicate 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, by the first configuration information, a set of time intervals between two adjacent transmissions of the positioning purpose reference signal, in addition to indicating, by the first configuration information, that the transmission period of the positioning purpose reference signal is the second number of time slots, i.e. the first configuration information gives a plurality of available time intervals. When a plurality of available time intervals (i.e., a set of time intervals) between two adjacent transmissions of the positioning-purpose reference signal are indicated by the first configuration information, one of the set of time intervals may be indicated by the second configuration information as a target time interval, so that the user equipment transmits the positioning-purpose reference signal with the second network device multiple 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 positioning purpose reference signals indicated by the first configuration information includes 4 time intervals, i.e., the first configuration information gives 4 available time intervals, T1, T2, T3 and T4, respectively, at this time, one of the set of time intervals may be indicated as a target time interval by the second configuration information, such as the second configuration information indicating time interval T1 as the target time interval, and accordingly, the user equipment may select the target time interval according to the time interval T1, the ue transmits the positioning-purpose reference signal with the second network device multiple times in one transmission period, for example, the second configuration information indicates the time interval T3 as the target time interval, and accordingly, the ue transmits the positioning-purpose reference signal with the second network device multiple times in one transmission period according to the time interval T3.

In an optional 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 as a target time interval through MAC signaling, or may indicate one time interval in the time interval set as a target time interval through DCI signaling.

In an alternative, the time intervals in the time interval set indicated by the first configuration information may be at a symbol level, that is, the time intervals in the time interval set include a fifth number of symbols, the fifth number is a positive integer, for example, a certain time interval is 2 symbols, a certain time interval is 4 symbols, a certain time interval is 7 symbols, a certain time interval is 14 symbols, a certain time interval is 28 symbols, and so on.

In an alternative, the time intervals in the time interval set indicated by the first configuration information may be at a time slot level, that is, the time intervals in the time interval set include a sixth number of time slots, for example, 1/4 time slots, 1/2 time slots, 1 time slot, 2 time slots, 4 time slots, and so on.

In an alternative, the time intervals in the time interval set indicated by the first configuration information may be slot-level and symbol-level, for example, there may be 2 symbols in the time interval, 7 symbols in the time interval, 1 slot in the time interval, 2 slots in the time interval, 4 slots in the time interval, and so on.

In a possible implementation manner 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-use reference signal, and the configuration information further includes second configuration information, where the second configuration information includes MAC information and DCI information, where the MAC information is used to indicate a candidate set of time intervals in the set of time intervals, and the DCI information is used to indicate one time interval in the candidate set of time intervals.

When the first network device indicates a plurality of available time intervals (i.e., time interval sets) between two adjacent transmissions of the positioning-purpose reference signal through the first configuration information, one time interval in the time interval set may be indicated as a target time interval through the second configuration information, so that the user equipment transmits the positioning-purpose 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 set of time intervals is indicated as the target time interval by the second configuration information, a candidate set of time intervals of the set of time intervals may be indicated by the MAC information, and one of the candidate set of time intervals is indicated as the target time interval by the DCI information.

In an example, if the set of time intervals between two adjacent transmissions of the positioning use reference signal indicated by the first configuration information includes 4 time intervals, that is, the first configuration information provides 4 available time intervals, which are T1, T2, T3 and T4, then the MAC information may indicate a candidate set of time intervals in the set of time intervals, for example, the candidate set of time intervals is T1, T2 and T3, for example, the candidate set of time intervals is T1, T2 and T4, and further for example, the candidate set of time intervals is T2 and T3.

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

In an alternative, the positioning-purpose reference signals include downlink positioning reference signals PRS used for positioning and uplink sounding reference signals SRS used for positioning (i.e., uplink sounding reference signals SRS for positioning). Based on this, in the process that the ue transmits the first number of positioning purpose reference signals with the second network device in one time slot according to the configuration information, the ue may send the first number of positioning purpose uplink sounding reference signals SRS to the second network device in one time slot according to the configuration information, for example, the ue sends the M number of positioning purpose uplink sounding reference signals SRS to the network device in one time slot according to the configuration information, where M is an integer greater than 1; the ue may also receive, according to the configuration information, a first number of downlink positioning reference signals PRS sent by the second network device in one timeslot, for example, receive M number of downlink positioning reference signals PRS sent by the network device in one timeslot.

In an optional manner, after receiving M times of downlink positioning reference signals PRS transmitted by the second network device in a timeslot, the user equipment may perform corresponding measurement according to the M times of downlink positioning reference signals PRS, and may feed back a measurement result to the network device after the measurement is completed.

It should be noted that, for the method that requires the second configuration information, if the transmission period given in the first configuration information may be infinite, in a limit case, this first configuration information may be omitted, and then only the second configuration information may be finally required to indicate, where the second configuration information may be any one or combination of multiple ones of the above-mentioned RRC information, MAC information, and DCI information.
