In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following further describes the embodiments of the present disclosure in detail with reference to the accompanying drawings.

In the NR Rel-16 system, reference signals for positioning are newly defined, including the downlink positioning reference signal PRS and the uplink sounding reference signal SRS for positioning. Among them, PRS mainly supports periodic transmission of PRS, and can support repeated transmission of PRS resources within a transmission period. However, for repeated transmission of PRS resources, it is necessary to configure the number of repeated transmissions and the time between two adjacent transmissions. The interval, and the time interval between two adjacent transmissions is in units of time slots, the time interval is N slots (time slots), and N is a natural number. In other words, the current PRS can only be sent once in a slot. Moreover, each PRS can occupy consecutive 2 or 4 or 6 or 12 symbols in a slot, and the starting symbol position can be any one of the 1st to 13th symbols in a slot.

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

The accuracy of the existing positioning scheme can only reach 10m (meters) and the delay can only reach 1s (seconds). However, in the upcoming NR Rel-17, because scenarios such as the industrial Internet of Things need to be considered, the positioning The accuracy and delay requirements are higher, for example, the accuracy is less than 1m (meter), and the delay is less than 100ms or even 10ms.

In a possible implementation, the positioning reference signal is a reference signal that can be used to determine the spatial position of the terminal. For example, the positioning reference signal includes, but is not limited to: a positioning reference signal PRS for positioning sent in the downlink direction, and As the downlink positioning reference signal; and the sounding reference signal SRS sent in the uplink direction for positioning, it is recorded as the uplink positioning reference signal. That is, the positioning reference signal may be a downlink positioning reference signal or an uplink positioning reference signal.

In an optional implementation manner, when the first network device and the second network device are the same, the above step S110 and step S120 can be expressed as: step S110, receiving a transmission from the first network device (or the second network device) The configuration information of the positioning reference signal, step S120, the user equipment performs the first number of transmissions of the positioning reference signal with the first network device (or the second network device) in a time slot according to the configuration information, and the first The degree is an integer greater than 1.

Among them, the configuration information of the positioning reference signal is based on the mini-slot configuration. For example, the configuration of the positioning reference signal can be transmitted multiple times in a time slot, that is, the transmission of the positioning reference signal is based on the mini-slot The transmission of the positioning reference signal, that is, the user equipment transmits the positioning reference signal with the second network device according to the configuration information. In fact, it performs the first number of positioning reference signals with the second network device in a time slot For transmission, the first number of times is an integer greater than 1.

The reference signal transmission method provided by the embodiments of the present disclosure transmits the positioning reference signal for the first time in one time slot according to the configuration information of the positioning reference signal, so that multiple positioning reference signals can be sent in one time slot , Realizes the transmission of reference signals for positioning purposes based on mini-slots, thereby improving positioning accuracy, reducing positioning delay, and meeting the requirements of the NR system for positioning technology.

The following specifically introduces the reference signal transmission method of the embodiment of the present disclosure:

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

The network device may be an LMF (Location Management Function, location management function entity), a base station, or a vehicle-mounted terminal device, of course, it may also be other network-side devices, which are not limited in the embodiments of the present disclosure. In an example, the network device may also refer to different transmitting and receiving 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, and access points. Types of user equipment include mobile phones, vehicle user terminals, tablet computers, laptop computers, personal digital assistants, mobile Internet devices, wearable devices, etc. The types of user equipment also include vehicle-mounted equipment terminals, IoT equipment terminals, and industrial IoT equipment terminals. In one example, in the vehicle networking communication, both the network device and the user equipment may be vehicle-mounted terminal devices.

In an optional manner, 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-mounted terminal device.

When the first network device is the LMF and the second network device is the base station, it is equivalent to that the user equipment receives the configuration information of the positioning reference signal sent by the LMF. Then, the user equipment performs the first time with the base station in a time slot according to the configuration information. One-time transmission of reference signals for positioning purposes.

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. Then, the user equipment performs the first time with the base station in a time slot according to the configuration information. One-time transmission of reference signals for positioning purposes.

The first network device may be a base station where the serving cell is located, and the second network device may be a base station where the serving cell is located, or a base station where a neighboring cell is located. The second network device may also be multiple different cells, different Transmission Reception Points (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, it is equivalent to that the user equipment receives the configuration information of the positioning reference signal sent by the LMF. Then, the user equipment communicates with the vehicle in a time slot according to the configuration information. The terminal device transmits the positioning reference signal for the first number of times.

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 equipment receives the configuration information of the positioning reference signal sent by the base station. Then, the user equipment communicates with the vehicle in a time slot according to the configuration information. The terminal device transmits the positioning reference signal for the first number of times.

In a possible implementation manner of the embodiment of the present disclosure, the reference signal identifiers of the positioning reference signals of the first number of transmissions in a time slot are all the same; or, the first number of transmissions in a time slot The reference signal identification of the reference signal for positioning purposes is different.

The positioning reference signal can be transmitted for the first number of times in one time slot, for example, M positioning reference signals are transmitted in one time slot, and M is an integer greater than 1.

On the one hand, the M positioning-purpose reference signals transmitted in one time slot may be repeated transmissions of the same positioning-purpose reference signal, that is, the reference signal identifiers of the positioning-purpose reference signals transmitted each time are the same. If the value of M is 3 and 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 identifiers of the M positioning reference signals transmitted in one time slot are different. In one case, the M positioning reference signals transmitted in a time slot include both X repetitive transmissions of the same positioning reference signal, and Y transmissions of different positioning reference signals, that is, X transmissions The reference signal identifiers of the positioning reference signals are the same, and the reference signal identifiers of the positioning reference signals transmitted in Y times are different, where X+Y=M. In another case, the reference signal identifiers of the M positioning reference signals transmitted in one time slot are different, that is, M different positioning reference signals are transmitted in one time slot, such as The first transmission is the downlink positioning reference signal PRS_1, the second transmission is the downlink positioning reference signal PRS_2, and so on, the Mth transmission is the downlink positioning reference signal PRS_M.

In a possible implementation manner of an embodiment of the present disclosure, the configuration information includes first configuration information, and the first configuration information is used to indicate that the transmission period of the positioning reference signal 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, may also be radio resource control RRC information, or may also be LPP information and RRC information. For example, the first network device configures the transmission period of the positioning reference signal through LPP signaling and/or RRC signaling. The transmission period may be less than one time 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 reference signal is the first number of symbols through the LPP information and/or the RRC information, for example, the transmission period is N symbols.

In addition to indicating that the transmission period of the positioning reference signal is the first number of symbols, the first configuration information may also indicate the position of the start symbol of the first transmission of the positioning reference signal and the number of symbols occupied by each transmission of the positioning reference signal. The number of symbols occupied by the reference signal for positioning purposes can be 1 symbol, 2 symbols, 4 symbols, 7 symbols, etc. per transmission. Since the transmission period of the positioning reference signal is the first number of symbols, when the first number is less than 14, it is possible to repeatedly transmit the positioning reference signal multiple times in one time slot.

For the downlink positioning reference signal PRS, the number of symbols occupied by the PRS can be one or two or four or six or twelve. In the first case, for a PRS that occupies 1 or 2 or 4 or 6 symbols, the transmission period can be half a slot. When a slot contains 12 symbols, the half 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, that is, the transmission period is 7 symbols. Then the number of transmissions in a time slot is 2 times.

In the second case, for a PRS that occupies 2 symbols, when the transmission period is 2 symbols, a slot can be transmitted 6 times (in this case, a slot includes 12 symbols) PRS or 7 times (in this case, one The time slot includes 14 symbols) PRS, that is, the number of transmissions in a time slot is 6 or 7 times; when the transmission period is 4 symbols, the PRS can be transmitted 3 times in a time slot, that is, the number of transmissions in a time slot It is 3 times; when the transmission period is 6 symbols, the PRS can be transmitted twice in a time slot, that is, the number of transmissions in a time slot is 2 times.

In the third case, for a PRS that occupies 4 symbols, when the transmission period is 4 symbols, the PRS can be transmitted 3 times in a slot, that is, the number of transmissions in a slot is 3; when the transmission period is With 6 symbols, the PRS can be transmitted twice in one time slot, that is, the number of transmissions in one time slot is 2 times.

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

In the second case, for an SRS that occupies 1 symbol, when the transmission period is 1 symbol, a slot can send 12 times (when a slot is 12 symbols) or 14 times (a slot is 14 symbols) Time) SRS, that is, the number of transmissions in a slot is 12 or 14; when the transmission period is 2 symbols, it can be sent 6 times in a slot (when a slot is 12 symbols) SRS or 7 times (one When the time slot is 14 symbols) SRS, that is, the number of transmissions in one time slot is 6 or 7 times; when the transmission period is 3 symbols, SRS can be sent 4 times in one time slot, that is, the transmission in one time slot The number of times is 4; when the transmission period is 4 symbols, SRS can be transmitted 3 times in one time slot, that is, the number of transmissions in one time slot is 3 times.

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

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

Wherein, the first configuration information indicates that the transmission period of the positioning reference signal is the second number of time slots, and can also indicate the number of repeated transmissions of the positioning reference signal and the time interval between two adjacent transmissions. Here, the positioning The number of repeated transmissions of the use reference signal may also be the repetition factor of the positioning use reference signal resource, and the time interval between two adjacent transmissions may also be the time interval between two adjacent repeated positioning use reference signal resources. The time interval is the third number of symbols, and the third number is a positive integer. For example, the first configuration information indicates that the time interval between two adjacent transmissions of the positioning reference signal is 0 symbol, 1 symbol, 2 symbols, 3 symbols, 4 symbols, 5 symbols, 6 symbols, and 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 also indicate the start symbol position of the first transmission of the positioning reference signal and the number of symbols occupied by each transmission of the positioning reference signal. For example, the start symbol position of the first transmission of the positioning reference signal can be the first symbol, the third symbol, and the fourth symbol of a time slot. For example, the number of symbols occupied by each transmission of the positioning reference signal is 1 Symbol, 2 symbols, 4 symbols, 7 symbols, etc.

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

In one embodiment, the symbol interval value is applicable within one time slot, but not between time slots. For example, for a PRS that occupies 4 symbols, if the time interval between two adjacent transmissions of the PRS is 0 symbols, for a time slot including 12 symbols, the PRS can be transmitted three times in a time slot, such as The symbols occupied by the three transmissions in the first time slot are the occupied symbols #0～#3 for the first transmission, the occupied symbols #4～#7 for the second transmission, and the occupied symbols #8～#11 for the third transmission. Then, in each subsequent time slot, the occupied symbols #0～#3 are sent for the first time, occupied symbols #4～#7 are sent for the second time, and occupied symbols #8～#11 are sent for the third time.

In another embodiment, the symbol interval value is applicable within a time slot and also between time slots. For example, for a PRS that occupies 4 symbols, if the time interval between two adjacent transmissions of the PRS is 0 symbols, for a time slot including 12 symbols, the PRS can be transmitted three times in a time slot, such as The symbols occupied by three transmissions in the first time slot slot#0 are the first transmission occupying slot#0 symbols #0～#3, the second transmission occupying slot#0 symbols #4～#7, and the third transmission. Sending occupies slot#0 symbols #8～#11. Then the fourth transmission occupies slot#0's symbol #12, symbol #13 and slot#1's symbol #0 and symbol #1, the second transmission occupies slot#1 symbol #2～#5, the third transmission Occupy slot#1, symbols #6～#19,..., and so on.

In one case, for a PRS that occupies 2 symbols, if the time interval between two adjacent transmissions of the PRS is 6 symbols, for a time slot including 12 symbols, it can be transmitted in one time slot Two PRS: If the time interval between two adjacent transmissions of the PRS is 7 symbols, for a time slot including 14 symbols, the PRS can be transmitted twice in one time slot.
