In order to better understand the technical solution of this application, the following content is first introduced:

Antenna polarization

The polarization of the antenna is determined by the polarization of electromagnetic waves. The polarization direction of electromagnetic waves is usually described by the spatial direction of its electric field vector, that is, at a certain position in space, looking along the propagation direction of the electromagnetic wave, the trajectory of its electric field vector in space changes with time. If this trajectory is a straight line, it is called linear polarization. If it is a circle, it is called circular polarization. It is also divided into left-hand polarization and right-hand polarization. Generally speaking, the polarization direction of the antenna is the direction of the electric field.

The electromagnetic field emitted by a circularly polarized antenna is a spiral beam, which has the following characteristics:

(1) Antenna radio frequency energy is emitted by a circular spiral antenna;

(2) The circular spiral beam has a multi-directional electromagnetic field and a wide range of electromagnetic fields, but its intensity is smaller than that of linearly polarized antennas.

The circular electromagnetic beam of a circularly polarized antenna can be sent in all directions simultaneously. When encountering obstacles, the electromagnetic beam of a circularly polarized antenna has strong elasticity and detour ability; however, the breadth of the circular beam also brings about relative differences in electromagnetic wave intensity. to lower.

The electromagnetic waves emitted by linearly polarized antennas are linear, and their electromagnetic fields have strong directionality and have the following characteristics:

(1) Radio frequency energy is emitted from the antenna in a linear manner;

(2) The linear beam has a unidirectional electromagnetic field. Compared with the circularly polarized antenna, the electromagnetic field is stronger, but the range is narrower and longer.

When circularly polarized waves pass through the rain and fog layer and ionosphere, there is little loss, and there is no problem of linearly polarized polarization plane rotation.

The network can specify a common polarization (polarization) in other system information (OSI) of non-system information block 1 (SIB1) to notify all UE networks (such as satellites) in The polarization type used for downlink transmission and uplink reception is as shown in Table 1 below;

Table 1

Uplink power control

In NR, the gNB determines the desired uplink transmit power and provides uplink transmit power control commands to the UE. The UE uses the provided uplink transmit power control command to adjust its transmit power.

The path loss estimated based on the downlink reference signal is one of the important factors in adjusting the uplink power. For example, for the Sounding Reference Signal (SRS) transmission used for positioning, the following method is used to determine the transmission power of the SRS:

If the UE transmits the SRS based on the configuration of the SRS-PosResourceSet set on the active UL BWP b of the carrier f of the serving cell c, the UE will use the SRS transmission power P _SRS,b,f,c (i, q _s ) is determined as:

-P _{O_SRS,b,f,c} (q _s ) and α _SRS,b,f,c (q _s ) are provided by p0-r16 and alpha-r16 respectively for activation of carrier f serving cell c UL BWP b above, the SRS resource set q _s is indicated by the SRS-PosResourceSetId in SRS-PosResourceSet, and

PL _{b, f, c} (q _d ) is the case where the DL-partial bandwidth (Bandwidth Part, BWP) of serving cell c is activated, Downlink path loss estimate, in dB, calculated by the UE using the RS resource index _qd for the SRS resource set _qs in the serving or non-serving cell. The configuration of the RS resource index q _d associated with the SRS resource set q _s is provided by pathlossReferenceRS-Pos.

- If ssb-IndexNcell is provided, referenceSignalPower is provided by ss-PBCH-BlockPower-r16;

- If dl-PRS-ResourceId is provided, referenceSignalPower is provided by dl-PRS-ResourcePower;

If the UE determines that the UE cannot accurately measure PL _{b, f, c} (q _d ), or the UE is not equipped with pathlossReferenceRS-Pos, the UE uses the synchronization from the serving cell used by the UE to obtain the Management Information Base (Management Information Base, MIB). Calculate PL _{b, f, c} (q _d ) using the RS resources obtained from the Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block;

In addition to the up to four paths that the UE maintains for each serving cell for Physical Uplink Shared Channel (PUSCH)/Physical Uplink Control Channel (PUCCH) transmission and SRS transmission configured by SRS-Resource In addition to loss estimates, the UE may also indicate the capability for multiple path loss estimates that the UE may simultaneously maintain for all SRS resource sets provided by the SRS-PosResourceSet.

Currently supported positioning technologies

The NG Radio Access Network (NG-RAN) can use one or more positioning methods to determine the location of the UE.

Locating a UE involves two main steps:

(1) Signal measurement; and

(2) Measurement-based position estimation and optional speed calculation.

Signal measurements may be performed by the UE or by the serving ng eNB or gNB. The basic signals measured for terrestrial positioning methods are usually LTE or NR radio transmissions; however, other methods can utilize other transmissions, such as universal radio navigation signals, including those from the Global Navigation Satellite System (GNSS).

Positioning capabilities should not be limited to a single method or measurement. That is, it should be able to utilize other standard methods and measurements as they are available and appropriate to meet the required service needs of location service customers. This additional information may include readily available Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) or NG-RAN measurements.

The location estimation calculation can be performed by the UE or location management function (LMF).

The standard positioning methods supported by NG-RAN access are:

(1) Network-assisted Global Navigation Satellite System (GNSS) method;

(2) Observed Time Difference of Arrival (OTDOA) positioning based on LTE signal;

(3) Enhanced cell ID method based on LTE signals;

(4) Wireless LAN positioning;

(5)Bluetooth positioning;

(6) Terrestrial Beacon System (TBS) positioning;

(7) Sensor-based method:

(8) Air pressure sensor;

(9)Motion sensor.

(10) NR enhanced cell ID method (NR E-CID) based on NR signals;

(11) Multiple round-trip time positioning (multi-RTT based on NR signals);

(12) Downlink deviation angle (DL AoD) based on NR signal;

(13) Downlink time difference of arrival (DL-TDOA) based on NR signals;

(14) Uplink time difference of arrival (UL-TDOA) based on NR signals;

(15) Uplink angle of arrival (UL AoA), including A-AoA and Z-AoA based on NR signals.

Hybrid targeting using multiple methods from the list of targeting methods above is also supported.

Standalone mode (e.g. autonomous, no network assistance) using one or more methods from the above list of positioning methods is also supported.

The supported UE positioning method versions are shown in Table 2:

Table 2

In standalone mode, sensor, WLAN, Bluetooth and TBS positioning methods based on MBS signals are also supported.

NR enhanced unit ID method

NR Enhanced Cell ID (NR E CID) positioning refers to a technique that uses additional UE measurements and/or gNB measurements to improve UE location estimation.

Although NR E-CID positioning can use some of the same measurements as the measurement control system in the RRC protocol, the UE generally does not perform additional measurements only for positioning purposes; i. For example, the positioning process does not provide measurement configuration or measurement control messages, and The UE reports its available measurements rather than being required to take additional measurement actions.

Multiple Round Trip Time (RTT) positioning

The multi-RTT positioning method utilizes UE Rx Tx time difference measurements and DL-PRS-RSRP for downlink signals received from multiple TRPs measured by the UE, and gNB measured at multiple TRPs for uplink signals sent from the UE. Rx Tx time difference measurement value and UL-SRS-RSRP.

The UE measures the UE Rx Tx time difference measurement (and optionally the DL-PRS-RSRP of the received signal) using the assistance data received from the positioning server, and the TRP measures the gNB Rx Tx time difference measurement (and the optional DL-PRS-RSRP of the received signal) using the assistance data received from the positioning server. UL-SRS-RSRP of the received signal). The measurements are used to determine the RTT at the positioning server, which is used to estimate the UE's location.

DL AoD positioning

The DL-AoD positioning method utilizes the measurement DL-PRS-RSRP of downlink signals received at the UE from multiple TPs. The UE uses the assistance data received from the positioning server to measure the DL-PRS-RSRP of the received signal, and the resulting measurements are used with other configuration information to position the UE relative to neighboring TPs.

DL-TDOA positioning

The DL-TDOA positioning method utilizes DL-RSTD (and optionally DL-PRS-RSRP) of downlink signals received at the UE from multiple TPs. The UE uses the assistance data received from the positioning server to measure the DL-RSTD (and optionally DL-PRS-RSRP) of the received signal, and the resulting measurements are used with other configuration information to position the UE relative to neighboring TPs.

UL-TDOA positioning

The UL-TDOA positioning method uses UL-RTOA (and optionally UL-SRS-RSRP) at multiple RPs of the uplink signal sent from the UE. RPs use assistance data received from the positioning server to measure the UL-RTOA (and optionally UL-SRS-RSRP) of the received signal, and the resulting measurements are used together with other configuration information to estimate the UE's location.

UL AoA

The UL-AoA positioning method utilizes the azimuth angle (A-AoA) and zenith angle (Z-AoA) measured at multiple RPs of the uplink signal transmitted from the UE. RPs use the assistance data received from the positioning server to measure the A-AoA and Z-AoA of the received signal, and the resulting measurements are used together with other configuration information to estimate the UE's location.

NTN scenarios are currently introduced in NR. The transmitter and receiver of NTN can use different polarization types, including left circular polarization, right circular polarization and linear polarization.

If the assumed receive polarization and transmit polarization are different, the path loss estimated at the receiving end may be inaccurate, for example, when the transmitter of the reference signal uses left circular polarization and the receiver side uses right circular polarization, due to the The signal may not contain the transmit signal and the estimated RSRP may be low, which means the estimated path loss may be closer to the TX power than the actual path loss. For power control of uplink transmission, if the UL transmission uses the same polarization as the downlink reception on the gNB side, and the uplink reception uses the same polarization as the downlink transmission in the satellite, then such a path is used The loss can indirectly compensate for the power loss caused by the difference in polarization between the transmitter and the receiver. However, due to the large RSRP, the terminal may be forced to use the maximum power, which will cause the terminal power loss to be large.

On the other hand, in positioning scenarios, measuring reference signals to estimate the distance or time between satellites and UEs requires accurate estimation of actual path loss and path delay without loss due to polarization differences.

According to the above, the RS used for path loss estimation or positioning measurement, when different polarizations are used in its transmitter and receiver, can be changed to other signals so that the same polarization is used in the transmitter and receiver, or It is allowed to send and receive signals using different polarization directions, but some method needs to be used to compensate for some polarization losses.

The signal polarization processing method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

Referring to Figure 2, an embodiment of the present application provides a signal polarization processing method, including:

Step 201: The first device receives the first signal from the second device. The first signal is sent by the second device according to the first preset rule and/or signaling configuration; that is, when the second device sends the first signal, it uses The polarization type can be determined according to the first preset rule, or configured through introduced signaling.

Step 202: The first device performs any of the following:

(1) The first device adjusts the polarization type used when sending the second signal to the second device according to the second preset rule;

(2) The first equipment performs compensation processing;

(3) The first device receives a third signal from the second device that meets the preset conditions;

The first preset rule is used by the second device to determine the polarization type used when sending the first signal, and the second preset rule is used by the first device to determine the polarization type used when sending the second signal.

The above polarization types can correspond to polarization in different directions, such as left-handed circular polarization, left-handed circular polarization, and linear polarization. wait.

In this embodiment of the present application, the first device and the second device are devices at both ends of signal transceiver communication. Specifically, the first device is a receiving device of the first signal, and the second device is a sending device of the first signal; the first device The device and the second device may specifically be a terminal or a network-side device. For example, the first device may be the terminal 11 and the second device may be a network-side device, or the first device may be a network-side device and the second device may be a terminal. , in the process of describing the embodiments in detail later, for the convenience of description, it is generally assumed that the first device may be a terminal. The second device may be a base station for description. It can be understood that the embodiments of the present application do not limit the specific types of the first device and the second device.

When different polarizations are used in the first device and the second device at both ends of the signal transmission and reception, the received signal can be changed to other signals so that the first device and the second device can reasonably adjust the polarization type, or compensate for some polarization losses, This allows signals with different polarizations to be sent and received, and avoids detection deviations caused by different polarizations. For example, when the terminal transmission power is determined based on the estimated path loss, the solution of this application can prevent the path loss estimation deviation caused by the different polarizations used in the transmitted and received signals, and can make the path loss estimation accurate, thereby determining a more accurate path loss. Accurate terminal power consumption; for example, in the case of positioning detection, the solution of this application can be used to prevent detection deviations caused by different polarizations of signals sent and received, making positioning detection more accurate.

In a possible implementation, the first preset rule includes any of the following:

(1) The polarization type used by the second device when sending the first signal is the same as the polarization type indicated in the system message sent by the second device;

(2) The polarization type used by the second device when sending the first signal is the same as the polarization type used by the second device when sending the system message.

In this embodiment of the present application, pre-rules are set for the polarization type used by the sending device, that is, the second device when sending signals. For example: the base station will indicate a polarization type through the system message (SIB1 and/or OSI), then it is specified that when the base station sends the first signal, the polarization type used should be the same as the polarization type indicated in the system message; or , stipulates that when the base station sends the first signal, the polarization type used by the base station should be the same as the polarization type used by the second device when sending the system message.

In this way, with the predetermined polarization type of the second device, the first device can learn the polarization type used by the second device when sending the first signal based on the polarization type indicated in the system message or the polarization type used when sending the system message. Polarization type, so as to use the same polarization type for signal reception to avoid deviations in the signal reception and detection process.

In a possible implementation, the method further includes:

The first device receives first signaling from the second device, and the first signaling is used to indicate the polarization type used by the second device when sending the first signal.

In this embodiment of the present application, when the second device sends the first signal, the polarization type it uses can be configured through the introduced signaling (ie, the first signaling). Then accordingly, the second device sends the first signaling Sent to the first device, the first device can learn the polarization type used by the second device when sending the first signal based on the indication of the first signaling.

In a possible implementation, the first signaling uniformly indicates the resource set in which the resources used by the first signal are located. That is, the first signaling may specifically indicate the entire resource set. For all resources in the resource set, First The polarization type of a signal makes a unified indication; or the first signaling independently indicates each resource in the resource set where the resource used by the first signal is located, that is, the first signaling can specifically indicate the entire resource set. The polarization type of the first signal on each resource is separately indicated, so that the polarization type of the first signal on each resource can be the same or different.

In a possible implementation, the first device adjusts the polarization type used when sending the second signal to the second device according to the second preset rule, including:

The first device adjusts the polarization type used when sending the second signal to be the same as the polarization type used by the first device when receiving the first signal.

In this embodiment of the present application, the first device adjusts the polarization type used for uplink transmission and the polarization type used for receiving downlink signals to be the same. In this way, for situations where path loss needs to be estimated based on the first signal, the estimated The pathloss will become larger due to the polarization loss when the transmitting and receiving polarization types are different, thus indirectly causing the polarization loss to be compensated in the uplink transmit power.

In a possible implementation, the first device performs compensation processing, including:

After receiving and/or measuring the first signal, the first device performs compensation processing according to the preset compensation.

In this embodiment of the present application, the sending end and the receiving end are allowed to use different polarizations, and preset compensation (such as power compensation or positioning information metric compensation) is introduced.

In a possible implementation, the preset compensation is determined by one or more of the following:

(1) Determined in advance;

(2) The preset scenes, such as the geostationary orbit (The Geostationary Orbit, GEO) scene and the low earth orbit (Low Earth Orbit, LEO) scene, can be different;

(3) A combination of the polarization type used by the first device when receiving signals and the polarization type used by the first device when sending signals;

(4) A combination of the polarization type used by the first device when receiving signals and the polarization type used by the second device when transmitting signals.

In a possible implementation, the preset conditions satisfied by the third signal include one or more of the following:

(1) The measurement metric obtained by measuring the third signal is greater than or equal to the preset threshold; the measurement metric can be Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), etc., For example, the preset condition is that the RSRP obtained by measuring the third signal is greater than or equal to the preset threshold.

(2) The polarization type used by the second device when sending the first signal is the same as the polarization type indicated in the system message sent by the second device.

In a possible implementation, the first device receives a third signal from the second device that meets preset conditions, including:

When the polarization type used by the second device when sending the first signal is different from the polarization type indicated in the system message sent by the second device, the first device receives a third signal from the second device that satisfies the preset condition. .

(1) The power of the second signal is determined;

(2) Road damage is determined;

(3) Determine positioning-related information;

(4) Positioning determined.

In a possible implementation, the method further includes:

The first device uses preconfigured or predefined transmission power or path loss of the second signal. For example, the first device directly uses the maximum power allowed to send the signal.

In a possible implementation, the first device uses preconfigured or predefined transmission power or path loss of the second signal, including:

In the case where the polarization type used by the second device when transmitting the first signal is different from the polarization type used by the first device when receiving the first signal, the first device uses a preconfigured or predefined transmission power of the second signal or Road damage.

(1) Sounding Reference Signal (SRS);

(2) Synchronization Signal and PBCH block (SSB);

(3) Positioning Reference Signal (PRS);

(4) Channel State Information-Reference Signal (CSI-RS).

The technical solutions implemented in this application are described below in conjunction with specific application examples:

Example 1: Signal polarization determination

In some embodiments, the polarization type of the signal used for measurement, such as SSB/CSI-RS/SRS/PRS, is the same as the polarization indicated in the system message.

In this case, after the UE obtains the polarization information used by the satellite from the system message, it can adjust the polarization type for receiving downlink signals and sending uplink signals.

For example, it can be specified that the UE does not expect to receive a polarization direction of the SSB that is different from the polarization direction indicated in the corresponding SIB.

In some embodiments, the polarization direction of the SSB has the same transmit polarization direction as the corresponding SIB1 and or OSI.

For example, a UE that can receive LHCP (left-hand circular polarization) SSB will receive the corresponding SIB1 and/or subsequent OSI, which are sent using LHCP; a UE that can receive RHCP SSB will receive the corresponding SIB1 and or subsequent OSI, are sent using RHCP

In some embodiments, for NTN scenarios, signaling configuration polarization information per SSB/CSI-RS/SRS can be introduced.

For example, for an SRS resource set used for positioning, the ntnPolarization parameter can be introduced to determine the polarization type used for sending it, for example:

Alternatively, for each SRS resource used for positioning, the ntnPolarization parameter can be introduced to determine the polarization type used for sending it, for example:

In some embodiments, if the polarization type used for the downlink signal (such as SSB or CSI-RS) used to estimate pathloss is different from the polarization type specified in the system message, one or more of the following methods can be used:

(1) Re-select a downlink signal for pathloss estimation. The downlink signal here needs to meet at least one of the following conditions:

(1.1) Its measured RSRP value is greater than a certain threshold

(1.2) Has the same polarization as system messages

(2) The polarization used for uplink transmission is the same as the polarization used for receiving downlink signals to estimate pathloss (SSB/CSI-RS).

In some embodiments, the transmitter and receiver are allowed to use different polarizations and introduce power compensation or positioning information metric compensation. The compensation may depend on one or more of the following factors and methods:

(1) Compensation is configured by the network and can be cell/UE/channel/signal specific;

(2) Determined in advance;

(3) It depends on different scenarios, such as GEO and LEO cases can be different;

(4) Depends on different {send (transport, TX) polarization, receive (receive, RX) polarization} combination;

For example, for the LEO scenario, the path loss (pathloss) compensation is predetermined as defined in Table 3 below;

table 3

Note that in the above example, the situation corresponding to the 9dB square can also be considered as a situation that the UE does not expect, because it may not receive any signal at this time, and the method in the previous embodiment can be used.

In some embodiments, the sender and receiver are allowed to use different polarization, in which case one or more of the following rules are used:

(1) Use predefined or network configured TX power

(2) Use predefined or network configured pathloss

For example, in this case, the terminal directly uses the maximum power PCmax allowed by the UE to send.

Example 2: Determining the polarization of the signal before sending the system message indicating polarization information

The signal before the system message indicating polarization information is sent is called the first target signal, which can be the PRACH signal, or other signals earlier than the OSI message carrying polarization.

In some embodiments, polarization is configured per SSB/CSI-RS in SIB1 or MIB, thus ensuring that the polarization of sending the first signal can be the same as the polarization of the SSB/CSI-RS associated with the first target signal.

In some embodiments, common polarization is configured in SIB1 or MIB, and polarization of SSB/CSI-RS is the same.

Example 3: Compensating polarization loss indirectly through pathloss

In some embodiments, it is specified that the polarization used to send the uplink is the same as the polarization used to receive the downlink signal used to measure the path loss.

The pathloss estimated in this way will become larger due to the polarization loss when the transmitting and receiving polarization is different, thus indirectly causing the polarization loss to be compensated in the uplink transmit power.
