Description

Information sending and receiving method, device and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information sending method, an information receiving method, an information sending device, an information receiving device, and an information receiving apparatus.

Background

Among the conventional Positioning methods, a Multiple-Round Trip Time (Multiple-Round Trip Time) Positioning method is an important Positioning method, and the measurement quantities adopted by the Multiple-Round Trip Time Positioning method are the DL-PRS (Downlink Positioning Reference Signal) arrival Time from each TRP (Transmit and Receive Point) measured by a UE (User Equipment or terminal), the Time difference (referred to as UE Transmit/Receive Time difference) between the UE sending SRS-Pos (Sounding Reference Signal for Positioning) and the Time difference (referred to as gNB Transmit/Receive Time difference) between the UE sending SRS-Pos arrival Time from the UE and the TRP sending DL-PRS (referred to as gNB Transmit/Receive Time difference) measured by each TRP.

The working principle of the Multi-RTT positioning method is as follows: the UE reports the acquired UE transceiving time difference to an LMF (Location Management Function), each TRP also provides the acquired gNB transceiving time difference to the LMF, and the LMF obtains the distance between the UE and each TRP by using the UE transceiving time difference and the gNB transceiving time difference. Then, other known information (e.g., the geographical coordinates of the TRP) is added to calculate the location of the UE.

As described above, for the Multi-RTT positioning method, in order to complete the measurement of the UE transmit/receive time difference or the gNB transmit/receive time difference, the TRP needs to transmit DL-PRS and the UE needs to transmit SRS-Pos, and then the UE or the gNB can complete the measurement of the related measurement quantity based on the DL-PRS and the SRS-Pos.

In the existing protocol, a pair of DL-PRS and SRS-Pos for calculating UE transceiving time difference measurement or gNB transceiving difference measurement may be transmitted in different frequency bands.

Taking the UE transceiving time difference as an example, if the TRP transmits DL-PRS in the first frequency band (band 1) and the UE transmits SRS-Pos in the second frequency band (band 2), the UE will pair the DL-PRS in the first frequency band with the SRS-Pos in the second frequency band to calculate the UE transceiving time difference, so that the DL-PRS in the first frequency band and the SRS-Pos in the second frequency band adjust the transmission time based on different Timing Advance Groups (TAGs) because the first frequency band and the second frequency band belong to different TAG, and the finally calculated UE transceiving time difference will be inaccurate, thereby affecting the final positioning accuracy.

As shown in fig. 1, an embodiment of the present invention provides an information sending method, which is applied to a communication device, where the communication device may be a terminal (UE) or a gNB (base station), and the method includes:

step 11, reporting first information associated with the first reference signal and the second reference signal in the related reporting information of the first measurement quantity; wherein the first reference signal and the second reference signal are used to measure a first measurement quantity; the first information includes at least one of first indication information indicating whether frequency bands of the first reference signal and the second reference signal are the same, frequency band index numbers of the first reference signal and the second reference signal, member carrier index numbers of the first reference signal and the second reference signal, serving cell index numbers of the first reference signal and the second reference signal, second indication information indicating whether timing advance group TAGs associated with the first reference signal and the second reference signal are the same, and TAG index numbers associated with the first reference signal and the second reference signal.

In this embodiment, first information associated with a first reference signal and a second reference signal is reported in report information related to the first measurement quantity, where the first measurement quantity may be a UE transmit-receive time difference measurement quantity or a gNB transmit-receive time difference measurement quantity, and the first reference signal includes at least one of a downlink positioning reference signal DL-PRS, a channel state information reference signal CSI-RS, and a synchronization signal block SSB; the second reference signal comprises at least one of sounding reference signal SRS-Pos for positioning, sounding reference signal SRS and physical random access channel PRACH.

Therefore, a Location Management Function (LMF) can judge whether the first measurement quantity belongs to the effective measurement quantity according to the first information, so that the LMF can decide to use the first measurement quantity or discard the first measurement quantity when calculating the RTT, the influence of the invalid measurement quantity on the RTT calculation accuracy is avoided, and the system location precision is improved.

In addition, in this embodiment, the timing advance group TAG associated with the first reference signal refers to a TAG to which one entity of a frequency band, a member carrier and a serving cell where the first reference signal is located belongs;

The TAG index number associated with the first reference signal refers to a TAG index number to which one entity belongs in a frequency band, a member carrier and a serving cell where the first reference signal is located;

In a first alternative embodiment of the present invention, the step 11 may include:

when the first measurement quantity is a UE transceiving time difference measurement quantity, reporting first information associated with the first reference signal and the second reference signal in related reporting information of the first measurement quantity. Further, according to the capability of the terminal, first information associated with the first reference signal and the second reference signal is reported in the related report information of the first measurement quantity.

Optionally, the first information includes: first association information associated with the first reference signal and second association information associated with the second reference signal; or the first information comprises: third association information associated with the first reference signal and the second reference signal at the same time.

In this embodiment, the UE reports the first information: in the report information related to the first measurement quantity, the UE reports first information associated with the first reference signal and the second reference signal.

The first measurement quantity refers to UE transceiving time difference measurement quantity, and the first reference signal refers to a downlink positioning reference signal for measuring the first measurement quantity; the second reference signal is an uplink positioning reference signal used for measuring the first measurement quantity; the first information may be a serving cell index number.

The first reference signal is a DL-PRS and the second reference signal is an SRS for positioning (SRS-Pos).

When the first measurement quantity is a UE transceiving time difference measurement quantity, for each first measurement quantity, the UE can report first information associated with the first reference signal and the second reference signal according to the UE capability;

if the first reference signal and the second reference signal are both measured on the same first entity, the UE does not report the first information. Wherein the first entity refers to a serving cell.

The first information associated with the first reference signal and the second reference signal refers to: one first information associated with the first reference signal and another first information associated with the second reference signal.

As shown in fig. 2, in order for the terminal UE1 to report the first measurement quantity (UE transceiving time difference measurement quantity), the UE1 needs to receive the first reference signal DL-PRS1 on the serving cell with the serving cell index 1 and the first reference signal DL-PRS2 on the serving cell with the serving cell index 2, and send the second reference signal SRS-Pos1 on the serving cell with the serving cell index 1 and the second reference signal SRS-Pos2 on the serving cell with the serving cell index 2, respectively. Then, according to the present invention, for each first measurement, the UE may report first information associated with the first reference signal and the second reference signal according to the UE capability. The "first information associated with the first reference signal and the second reference signal" as used herein refers to: one first information associated with the first reference signal and another first information associated with the second reference signal, namely: serving cell index 1 associated with DL-PRS1, serving cell index 2 associated with DL-PRS, serving cell index 1 associated with SRS-Pos1, serving cell index 2 associated with SRS-Pos 2.

Optionally, if the first reference signal and the second reference signal are both measured on the same first entity, the UE does not report the first information, where the first entity refers to at least one of a frequency band, a component carrier, a serving cell, and a TAG.

As shown in fig. 3, all of the first reference signals DL-PRS1 and DL-PRS2, and all of the second reference signals SRS-Pos1 and SRS-Pos2, are measured on the same first entity, namely: all measured on the same serving cell (serving cell index 1), the UE does not report the first information. This is because since all reference signals are on the same first entity, there is no need to report the first information. If the first information is not reported, the LMF defaults that all the first reference signals and the second reference signals for measuring the first measurement quantity are located on the same first entity.

By adopting the method in the embodiment, the LMF can be assisted to judge whether the receiving and sending time difference measurement quantity belongs to the effective measurement quantity by indicating the frequency band information associated with the downlink positioning reference signal and the uplink positioning reference signal, so that the influence of the invalid measurement quantity on the RTT calculation accuracy is avoided, and the system positioning precision is improved.

In a second alternative embodiment of the present invention, the step 11 may include:

In this embodiment, the gNB reports the first information: in the first measurement reporting information, the gNB reports first information associated with the first reference signal and the second reference signal.

When the first measurement quantity is a gNB transmit-receive time difference measurement quantity, for each first measurement quantity, the gNB may report first information associated with the first reference signal and the second reference signal;

if the first reference signal and the second reference signal are both measured on the same first entity, the gNB does not report the first information. Wherein the first entity refers to a serving cell.

As shown in fig. 2 again, in order for the base station gNB1 to report the first measurement quantity (gNB transmit-receive time difference measurement quantity), the gNB1 needs to respectively transmit a first reference signal DL-PRS1 on the serving cell with the serving cell index 1 and a first reference signal DL-PRS2 on the serving cell with the serving cell index 2, and receive a second reference signal SRS-Pos1 on the serving cell with the serving cell index 1 and a second reference signal SRS-Pos2 on the serving cell with the serving cell index 2. Then, according to this embodiment of the present invention, for each first measurement, the gNB may report first information associated with the first reference signal and the second reference signal. The "first information associated with the first reference signal and the second reference signal" as used herein refers to: one first information associated with the first reference signal and another first information associated with the second reference signal, namely: serving cell index 1 associated with DL-PRS1, serving cell index 2 associated with DL-PRS, serving cell index 1 associated with SRS-Pos1, serving cell index 2 associated with SRS-Pos 2.

Optionally, if the first reference signal and the second reference signal are both measured on the same first entity, the gNB does not report the first information, where the first entity refers to at least one of a frequency band, a component carrier, a serving cell, and a TAG.

As further shown in fig. 3, all of the first reference signals DL-PRS1 and DL-PRS2, and all of the second reference signals SRS-Pos1 and SRS-Pos2, are measured on the same first entity, namely: are all measured on the same serving cell (cell index 1), and the gNB does not report the first information. This is because since all reference signals are on the same first entity, there is no need to report the first information. If the first information is not reported, the LMF defaults that all the first reference signals and the second reference signals for measuring the first measurement quantity are located on the same first entity.

In a third optional embodiment of the present invention, the first information includes first indication information whether frequency bands of the first reference signal and the second reference signal are the same, where the first indication information uses 1-bit indication.

In a fourth optional embodiment of the present invention, the band index number includes: a physical band index number or a logical band index number;

Optionally, the index numbers of the physical frequency bands are expressed by 10 bits, and each index number represents an index number of a frequency band in which the first reference signal or the second reference signal is located.
