For a better understanding of the technical solution of the present application, the following description will be given first:

antenna polarization

The polarization of the antenna is determined by the polarization of the electromagnetic wave. The polarization direction of an electromagnetic wave is generally described in terms of the spatial orientation of its electric field vector, i.e., the trajectory that its electric field vector describes in terms of its orientation in space as seen in the propagation direction of the electromagnetic wave, at a certain position in space. If the track is a straight line, it is called linear polarization, and if it is a circle, it is called circular polarization, and it is classified into left-hand polarization and right-hand polarization. Generally, the antenna polarization direction is the direction of the electric field.

The electromagnetic field of the circularly polarized antenna is emitted into a spiral wave beam, and the circularly polarized antenna has the following characteristics:

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

(2) Circular helical beams have a multi-directional electromagnetic field with a wide range of fields, but with a lower intensity than linear polarized antennas.

The circular electromagnetic beam of the circularly polarized antenna can be transmitted in all directions simultaneously. When encountering obstacles, the electromagnetic wave beam of the circularly polarized antenna has stronger elasticity and detour capability; the broad range of circular beams also brings about a relative decrease in electromagnetic wave intensity.

Electromagnetic waves emitted by the linear polarized antenna are linear, and the electromagnetic field has stronger directivity and has the following characteristics:

(1) Wireless radio frequency energy is transmitted from an antenna in a linear fashion;

(2) The linear beam has a unidirectional electromagnetic field, which is stronger than a circularly polarized antenna, but has a narrower range.

When the circularly polarized wave passes through the rain and fog layer and the ionized layer, the loss is less, and the problem of rotation of the linearly polarized polarization plane does not exist.

The network may specify a common polarization (OSI) in other system information (other system information, OSI) than system information block 1 (system information block, sib1), informing all UEs of the type of polarization used by the network (e.g., satellite) for downlink transmission and uplink reception, 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 adjusts its transmit power using the provided uplink transmit power control commands.

The path loss estimated based on the downlink reference signal is one of the important factors for adjusting the uplink power. For example, for SRS transmission for positioning, the following manner is used to determine the transmission power of the SRS signal:

If the UE transmits SRS based on the configuration of SRS-posresource set on the active UL BWP b of carrier f of the serving cell c, the UE transmits SRS transmission power P in SRS transmission occasion i _SRS,b,f,c (i,q _s ) The method comprises the following steps:

-P _{O_SRS,b,f,c} (q _s ) And alpha _SRS,b,f,c (q _s ) Provided by p0-r16 and alpha-r16, respectively, for serving cell c on active UL BWP b of carrier f, SRS resource set q _s Indicated by SRS-PosResourceSetid in SRS-PosResourceSet, and

PL _b,f,c (q _d ) Is in case of an active DL-BWP of the serving cell c, the set q of SRS resources in the serving or non-serving cell is used by the UE _s RS resource index q of (2) _d The downlink pathloss estimate calculated is in dB. And SRS resource set q _s Associated RS resource index q _d Is provided by pathloss reference rs-Pos.

-if ssb-indixncell is provided, the reference signalpower is provided by ss-PBCH-BlockPower-r 16;

-if dl-PRS-resource id is provided, the prefercesignalpower is provided by dl-PRS-resource power;

if the UE determines that the UE cannot accurately measure PL _b,f,c (q _d ) Or the UE is not equipped with a pathloss reference RS-Pos, the UE calculates PL using RS resources obtained from an SS/PBCH block of a serving cell used by the UE to acquire the MIB _b,f,c (q _d )；

In addition to up to four pathloss estimates maintained by the UE for PUSCH/PUCCH transmissions and SRS transmissions configured by SRS-Resource for each serving cell, the UE may also indicate the capability for multiple pathloss estimates that the UE may maintain for all SRS Resource sets provided by SRS-posresource sets simultaneously.

Currently supported positioning techniques

The NG-RAN may use one or more positioning methods to determine the location of the UE.

Positioning the UE includes two main steps:

(1) Measuring signals; and

(2) A position estimate based on the measurements and an optional velocity calculation.

Signal measurements may be made by the UE or by the serving ng eNB or gNB. The basic signal measured for the terrestrial positioning method is typically LTE or NR radio transmission; however, other methods may utilize other transmissions, such as general radio navigation signals, including signals from the Global Navigation Satellite System (GNSS).

The positioning function should not be limited to a single method or measurement. That is, it should be able to utilize other standard methods and measurements, as these are available and appropriate to meet the required service requirements of the location services client. Such additional information may include readily available evolved universal mobile telecommunications system terrestrial radio access network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) or NG-RAN measurements.

The position estimate calculation may be performed by the UE or a location management function (location management function, LMF).

The standard positioning method supported by the NG-RAN access comprises the following steps:

(1) A network assisted global navigation satellite system (Global Navigation Satellite System, GNSS) method;

(2) Positioning based on observed time difference of arrival (Observed Time Difference of Arrival, OTDOA) of the LTE signals;

(3) An enhanced cell ID method based on LTE signals;

(4) Positioning a wireless local area network;

(5) Bluetooth positioning;

(6) A terrestrial beacon system (Terrestrial Beacon System, TBS) location;

(7) A sensor-based method:

(8) An air pressure sensor;

(9) A motion sensor.

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

(11) Multiple round trip time positioning (multiple RTTs based on NR signals);

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

(13) Based on the downlink time difference of arrival (DL-TDOA) of the NR signal;

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

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

Hybrid positioning using multiple methods in the above list of positioning methods is also supported.

Also supported are standalone modes (e.g., autonomous, unassisted) that use one or more of the methods in the list of positioning methods described above.

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

TABLE 2

In the standalone mode, MBS signal based sensor, WLAN, bluetooth and TBS positioning methods are also supported.

NR enhanced Unit ID method

NR enhanced cell ID (NR E CID) positioning refers to techniques that use additional UE measurements and/or gNB measurements to improve UE position estimation.

Although NR E-CID positioning may use some of the same measurements as the measurement control system in the RRC protocol, the UE typically does not make additional measurements for positioning purposes only; i. for example, the positioning procedure does not provide a measurement configuration or measurement control message, and the UE reports its available measurements, rather than being required to take additional measurement actions.

Multi Round Trip Time (RTT) positioning

The multi-RTT positioning method uses UE Rx Tx time difference measurement and DL-PRS-RSRP of downlink signals received from a plurality of TRPs measured by a UE, and gNB Rx Tx time difference measurement and UL-SRS-RSRP measured at a plurality of TRPs of uplink signals transmitted from the UE.

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

DL AoD positioning

The DL-AoD positioning method utilizes measured DL-PRS-RSRP of downlink signals received at the UE from a plurality of tps. The UE uses 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 location 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 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

UL-TDOA location methods use UL-RTOA (and optionally UL-SRS-RSRP) at multiple RPs of the uplink signal transmitted from the UE. The RPs uses assistance data received from the positioning server to measure 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 location of the UE.

UL AoA

The UL-AoA positioning method uses azimuth (A-AoA) and zenith angles (Z-AoA) measured at a plurality of RPs of an uplink signal transmitted from a UE. The RPs uses assistance data received from the positioning server to measure the A-AoA and Z-AoA of the received signals and the resulting measurements are used together with other configuration information to estimate the location of the UE.

NTN scenes are currently introduced in NR. Different polarization types can be used for the transmitting end and the receiving end of the NTN, including left circular polarization, right circular polarization and linear polarization.

If the assumed received and transmitted polarizations are different, the estimated path loss 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, the estimated RSRP may be low because the received signal may not contain the transmitted signal, which means that the estimated path loss may be close to the TX power instead of the actual path loss. For power control of uplink transmission, if UL transmission uses the same polarization as downlink reception at the gNB side and uplink reception uses the same polarization as downlink transmission in satellite, power loss due to difference in polarization of transmitting and receiving ends can be indirectly compensated using such path loss. However, due to the larger RSRP, the terminal may be forced to use maximum power, which may result in a significant terminal power loss.

On the other hand, in a positioning scenario, the reference signal is measured to estimate the distance or time between the satellite and the UE, and it is necessary to accurately estimate the 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 may be changed to other signals when different polarizations are used in its transmitter and receiver, so that the same polarization is used in the transmitter and receiver, or signals are allowed to be transceived using different polarization directions, but some polarization losses need to be compensated for by some method.

The signal polarization processing method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

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

step 201: the first equipment receives a first signal from the second equipment, wherein the first signal is sent by the second equipment according to a first preset rule and/or signaling configuration; i.e. the second device sends the first signal, the type of polarization it uses may be determined according to a first preset rule or configured by means of incoming signalling.

Step 202: the first device performs any one of:

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

(2) The first equipment performs compensation processing;

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

The above polarization types may correspond to polarizations in different directions, for example: left-hand circular polarization, linear polarization, etc.

In the embodiment of the application, the first device and the second device are devices at two ends of signal receiving and transmitting communication, specifically, the first device is a receiving device of a first signal, and the second device is a transmitting device of the first signal; the first 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, 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. The second device may be described as an example of a base station, and it is understood that the embodiment of the present application does 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 the two ends of the signal transceiving, the received signal can be changed into other signals, so that the first device and the second device reasonably adjust the polarization types or compensate some polarization losses, thereby achieving the purpose of allowing the signals transceiving with different polarizations to be used and avoiding detection deviation caused by different polarizations. For example, under the condition of determining the terminal transmitting power according to the estimated path loss, the scheme of the application can prevent the path loss estimation deviation caused by different polarizations used by the received and transmitted signals, and can make the path loss estimation accurate, thereby determining more accurate terminal power consumption; for example, under the condition of positioning detection, the scheme of the application can prevent detection deviation caused by different polarizations used by the received and transmitted signals, so that the positioning detection is more accurate.

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

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

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

In the embodiment of the application, the polarization type used by the transmitting device, namely the second device when transmitting the signal is set in advance. For example: the base station indicates a polarization type via a system message (SIB 1 and/or OSI), and then specifies that the base station should use the same polarization type as indicated in the system message when transmitting the first signal; alternatively, it is provided that the base station should use the same type of polarization as the second device when transmitting the system message when transmitting the first signal.

Thus, the first device can know the polarization type used when the second device transmits the first signal based on the polarization type indicated in the system message or the polarization type used when the system message is transmitted by the first device, so that the same polarization type is used for signal reception, and deviation in the signal receiving and detecting processes is avoided.

In one possible embodiment, the method further comprises:

the first device receives first signaling from the second device, the first signaling indicating a type of polarization used by the second device when transmitting the first signal.

In the embodiment of the application, when the second device sends the first signal, the polarization type used by the second device can be configured through the introduced signaling (namely the first signaling), and accordingly, the second device sends the first signaling to the first device, and the first device can know the polarization type used when the second device sends the first signal based on the indication of the first signaling.

In one possible implementation manner, the first signaling indicates the resource set where the resources used by the first signal are located in a unified manner, that is, the first signaling may specifically indicate the whole resource set, and indicates the polarization type of the first signal on all the resources of the resource set in a unified manner; or, the first signaling indicates each resource in the resource set where the resource used by the first signal is located independently, that is, the first signaling specifically may indicate the polarization type of the first signal on each resource in the whole resource set separately, so that the polarization types of the first signals on each resource may be the same or different.

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

the first device adjusts the type of polarization used when transmitting the second signal to be the same as the type of polarization used when the first device receives the first signal.

In the embodiment of the 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, so that when the path loss (path) is required to be estimated according to the first signal, the estimated path is increased due to the polarization loss under the condition that the receiving and transmitting polarization types are different, and the polarization loss is indirectly compensated on uplink transmission power.

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

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

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

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

(1) Pre-determining;

(2) Preset scenes, such as a geostationary Orbit (The Geostationary Orbit, GEO) scene and a Low Earth Orbit (LEO) scene, may be different;

(3) A combination of a polarization type used when the first device receives the signal and a polarization type used when the first device transmits the signal;

(4) A combination of the type of polarization used when the first device receives the signal and the type of polarization used when the second device transmits the signal.

In one possible embodiment, the preset condition met by the third signal includes one or more of the following:

(1) The measurement metric obtained by measuring the third signal is larger than or equal to a preset threshold value; the measurement metric may be a reference signal received power (Reference Signal Receiving Power, RSRP), a reference signal received quality (Reference Signal Receiving Quality, RSRQ), etc., e.g., the preset condition is that the RSRP resulting from measuring the third signal is greater than or equal to a preset threshold.

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

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

And under the condition that the polarization type used when the second device sends 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 meeting the preset condition from the second device.

In one possible embodiment, the method further comprises:

the first device performs one or more of the following in accordance with the third signal:

(1) Determining the power of the second signal;

(2) Determining the path loss;

(3) Determining positioning related information;

(4) And (5) positioning and determining.

In one possible embodiment, the method further comprises:

the first device uses a pre-configured or predefined transmit power or path loss of the second signal. For example, the first device directly transmits using the maximum power allowed.

In one possible implementation, the first device uses a pre-configured or predefined transmit power or path loss of the second signal, including:

in case the type of polarization used when the second device transmits the first signal is different from the type of polarization used when the first device receives the first signal, the first device uses a pre-configured or predefined transmission power or path loss of the second signal.

In one possible implementation, the first signal is used to estimate a path loss, which is used to determine the transmit power of the second signal.

In one possible implementation, the first signal and the second signal comprise one or more of the following:

(1) Sounding reference signals (Sounding Reference Signal, SRS);

(2) Synchronization signals and physical broadcast channel blocks (Synchronization Signal and PBCH block, SSB);

(3) Positioning reference signals (Positioning Reference Signal, PRS);

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

The following describes the technical scheme of the application with reference to specific application examples:

example one: signal polarization determination

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

In this case, after the UE acquires the polarization information for the satellite from the system message, the polarization type of the received downlink signal and the transmitted uplink signal may be adjusted.

For example, provision may be made for: the UE does not expect to receive the SSB in a different polarization direction than 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 capable of receiving LHCP (left hand circularly polarized) SSB, correspondingly received SIB1 and/or subsequent OSI, are transmitted using LHCP; UE capable of receiving RHCP SSB, corresponding received SIB1 and or subsequent OSI, are transmitted by RHCP

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

For example, for SRS resource set for positioning, an ntn polarization parameter may be introduced for determining the type of polarization used for its transmission, for example:

alternatively, for each SRS resource for positioning, an ntn polarization parameter may be introduced for determining the type of polarization used for its transmission, for example:

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

(1) Reselecting a downstream signal for path estimation, where the downstream signal is required to satisfy at least one of the following conditions

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

(1.2) having the same polarization as the System message

(2) The uplink transmission uses the same polarization as the reception of the downlink signal for estimating pathloss (SSB/CSI-RS).

In some embodiments, the transmitting and receiving ends are allowed to use different polarization and introduce power compensation or positioning information metric compensation, which may depend on one or more of the following factors and methods:

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

(2) Pre-determining;

(3) Depending on the different scenarios, such as GEO and LEO cases may be different;

(4) Depending on the different { TX polarization, RX polarization } combinations;

for example, for LEO scenarios, the following Table 3 is defined to predetermine pathloss compensation;

TABLE 3 Table 3

Note that in the above example, the case where 9dB square corresponds may also be regarded as a case where the UE does not expect to occur, because at this time, any signal may not be received, and the method of the previous embodiment may be used.

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

(1) TX power using predefined or network configuration

(2) Pathloss using predefined or network configuration

For example, in this case, the terminal directly transmits using the maximum power PCmax allowed by the UE.

Example two: polarization determination of signal before transmission of system message indicating polarization information

The signal before transmission of the system message indicating the polarization information, which is referred to as the first target signal, may be a PRACH signal or other signal earlier than the OSI message carrying polarization.

In some embodiments, the configuration of the polization of the per SSB/CSI-RS in SIB1 or MIB ensures that the polization of the transmitted first signal may be the same as the polization of the SSB/CSI-RS associated with the first target signal.

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

Example three: compensating for polarization losses indirectly through pathloss

In some embodiments, the polarization specified to transmit the upstream is the same as the polarization used to receive the downstream signal for measuring path loss.

The estimated pathloss becomes larger by polarization loss when the transmit/receive polarization is different, so that the polarization loss is indirectly compensated for the uplink transmit power.
