[0088] With the development of New Radio (NR) access technology (e.g., 5G), a wide range of use cases can be realized, including enhanced mobile broadband, massive machine type communication (MTC), critical MTC, etc. In order to expand the utilization of NR access technology, 5G connectivity via satellite and / or airborne vehicles is considered to be a promising application. Figure 5 Satellite 506, Figure 6 A network (e.g., a satellite 606 in FIG. 604 ) that performs the functions of a ground base station (in whole or in part) Figure 3 The BS 302 in the terrestrial network is called a non-terrestrial network (NTN).

[0089] In NTN, the coverage of satellites or airborne vehicles is usually achieved by multiple beams. Similar to typical terrestrial networks, resource (e.g., frequency) reuse can be adopted between beams to improve resource efficiency.

[0090] For example, Figure 1A block diagram of an example frequency reuse scheme for a region according to some embodiments of the present disclosure is shown. The frequency reuse scheme 100 divides a region into multiple non-overlapping cells so that the entire frequency range can be utilized without interference. Each cell corresponds to a unique physical layer cell identifier (PCI) (e.g., PCI0, PCI1, etc.) and is collectively associated with synchronization signal block 0 (SSB0). As shown, the frequency reuse scheme 100 applies a three-group scheme, in which a first frequency (e.g., F0) can be reused across a first group of cells (e.g., cell 0, cell 3, cell 6, and cell 9), a second frequency (e.g., F1) can be reused across a second group of cells (e.g., cell 1, cell 4, cell 7, and cell 10), and a third frequency (e.g., F2) can be reused across a third group of cells (e.g., cell 2, cell 5, cell 8, and cell 11). In some embodiments, some or all of the frequencies (e.g., F0, F1, and F2) may be different in order to reduce interference between cells. Although Figure 1 Only a selected number of frequencies are shown to be reused between a selected number of cells, but any number of frequencies may be used between any number of cells within a region.

[0091] In some embodiments, UEs with very small aperture terminal (VSAT) antennas (e.g., Figure 3 UE 304 in the wireless communication network may use circular polarization in its transmission and reception. Therefore, frequency reuse using circular polarization may be another resource reuse option.

[0092] For example, Figure 2A block diagram of an example frequency reuse scheme for a region using circular polarization according to some embodiments of the present disclosure is shown. The frequency reuse scheme 200 divides the region into multiple non-overlapping cells so that the entire frequency range can be utilized without interference. Each cell corresponds to a unique PCI (e.g., PCI0, PCI1, etc.) and is associated with SSB0 in common. As shown, the frequency reuse scheme 200 applies four groups of schemes based on the use of different frequencies and different polarization capabilities. That is, a first frequency (e.g., F0) can be reused across a first group of cells (e.g., cell 0, cell 1, cell 4, cell 5, cell 8, cell 9, cell 12, and cell 13), and a second frequency (e.g., F1) can be reused across a second group of cells (e.g., cell 2, cell 3, cell 6, cell 7, cell 10, cell 11, cell 14, and cell 15). A third group of cells (e.g., cell 0, cell 2, cell 4, cell 6, cell 8, cell 10, cell 12, and cell 14) may use left-hand circular polarization (LHCP), and a fourth group of cells (e.g., cell 1, cell 3, cell 5, cell 7, cell 9, cell 11, cell 13, and cell 15) may use right-hand circular polarization (RHCP). In some embodiments, one or two frequencies (e.g., F0 and F1) may be different to reduce interference between cells. Although Figure 2 Only a selected number of frequencies are shown to be reused across a selected number of cells using selected polarization capabilities, but any number of frequencies may be used across any number of cells within a region and using any polarization capability (e.g., LHCP, RHCP, linear polarization, cross-linear polarization, etc.).

[0093] On the one hand, the polarization information of adjacent beams can be used for beam switching. In some NTN scenarios, such as low earth orbit (LEO) and high altitude platform station (HAPS), vehicle-mounted BSs may move at high speed, which means that even fixed UEs on the ground require frequent beam switching. In this case, the known polarization of the target beam can help the UE complete its beam switching faster. On the other hand, polarization can be used as an additional diversity dimension to improve network performance. For example, polarization can be used for interference mitigation.

[0094] However, in conventional 5G NR systems, the UE does not share its polarization information and / or capabilities with the BS, and the BS is not even configured to perform resource switching based on polarization information. Therefore, resource switching in conventional 5G NR systems is usually performed in an inefficient manner.

[0095] Therefore, the systems and methods discussed herein improve resource switching efficiency by utilizing the polarization capabilities of beams in the network.

[0096] As non-limiting examples, as discussed in more detail below, embodiments described herein may include one or more of the following features:

[0097] The "first feature" involves the UE sending a signal to the BS (e.g. Figure 3 BS 302 in the UE (e.g., Figure 3 The polarization capability of the UE 304 in FIG.

[0098] The "second feature" involves the BS indicating the polarization of resources (eg, cell / target spot beam / neighboring beam / bandwidth portion) to one or more UEs.

[0099] The "third feature" relates to providing service to one or more UEs with different polarization capabilities in a time division duplex (TDD) manner with scheduling period indication.

[0100] The "fourth feature" relates to a polarization change request (eg, indication of change) from a BS to a UE with a time interval (eg, space, opening, interruption, etc.).

[0101] The systems and methods disclosed herein have advantages over conventional systems. For example, known polarization information (sometimes referred to as "polarization capability") of a target cell / SSB / beam / BWP can save UE processing time and power by avoiding blindly trying possible polarization directions. As another example, known polarization information of a neighboring cell / SSB / beam / BWP can save UE processing time and power by avoiding blindly trying possible polarization directions in beam switching. As another example, UEs with different polarization capabilities in the same area can be served by polarization switching of the BS in a TDD manner. As another example, polarization can be used as an additional diversity dimension to mitigate interference.

[0102] 1. Mobile communication technology and environment

[0103] Figure 3 An example wireless communication network and / or system 300 is shown in which the techniques disclosed herein may be implemented in accordance with an embodiment of the present disclosure. In the following discussion, the wireless communication network 300 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as "network 300." Such an example network 300 includes a base station 302 (hereinafter referred to as "BS 302"; also referred to as a wireless communication node) and a user equipment 304 (hereinafter referred to as "UE 304"; also referred to as a wireless communication device) that may communicate with each other via a communication link 310 (e.g., a wireless communication channel), and a cluster of cells 326, 330, 332, 334, 336, 338, and 340 covering a geographic area 301. In Figure 3, BS 302 and UE 304 are contained within the respective geographic boundaries of cell 326. Each of the other cells 330, 332, 334, 336, 338, and 340 may include at least one base station operating with its allocated bandwidth to provide adequate radio coverage to its intended users.

[0104] For example, BS 302 may operate with an allocated channel transmission bandwidth to provide sufficient coverage to UE 304. BS 302 and UE 304 may communicate via downlink radio frames 318 and uplink radio frames 324, respectively. Each radio frame 318 / 324 may be further divided into subframes 320 / 327, which may include data symbols 322 / 328. In the present disclosure, BS 302 and UE 304 are described herein as non-limiting examples of "communication nodes", which may generally implement the methods disclosed herein. According to various embodiments of the present solution, such communication nodes may be capable of wireless and / or wired communication.

[0105] Figure 4 A block diagram of an exemplary wireless communication system 400 for sending and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some embodiments of the present solution is shown. The system 400 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, as described above, the system 400 may be used in applications such as Figure 3 Data symbols are communicated (eg, sent and received) in a wireless communication environment of wireless communication environment 300 .

[0106] The system 400 generally includes a base station 402 (hereinafter referred to as "BS 402") and a user equipment 404 (hereinafter referred to as "UE 404"). The BS 402 includes a BS (base station) transceiver module 410, a BS antenna 412, a BS processor module 414, a BS memory module 416, and a network communication module 418, each of which is coupled to and interconnected with each other via a data communication bus 420 as needed. The UE 404 includes a UE (user equipment) transceiver module 430, a UE antenna 432, a UE memory module 434, and a UE processor module 436, each of which is coupled to and interconnected with each other via a data communication bus 440 as needed. The BS 402 communicates with the UE 404 via a communication channel 450, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0107] As will be appreciated by those skilled in the art, the system 400 may also include Figure 4Any number of modules outside the modules shown. It will be appreciated by those skilled in the art that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any actual combination thereof. In order to clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are generally described according to their functions. Whether this function is implemented as hardware, firmware, or software may depend on the specific application and design constraints imposed on the entire system. People familiar with the concepts described herein can implement this function in an appropriate manner for each specific application, but this implementation decision should not be interpreted as limiting the scope of the present disclosure.

[0108] According to some embodiments, the UE transceiver 430 may be referred to herein as an "uplink" transceiver 430, which includes a radio frequency (RF) transmitter and an RF receiver, each of which includes circuitry coupled to an antenna 432. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in a time duplex manner. Similarly, according to some embodiments, the BS transceiver 410 may be referred to herein as a "downlink" transceiver 410, which includes an RF transmitter and an RF receiver, each of which includes circuitry coupled to an antenna 412. The downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 412 in a time duplex manner. The operation of the two transceiver modules 410 and 430 may be coordinated in time so that the uplink receiver circuit is coupled to the uplink antenna 432 to receive transmissions over the wireless transmission link 450 while the downlink transmitter is coupled to the downlink antenna 412. Instead, the operation of the two transceivers 410 and 430 may be coordinated in time such that the downlink receiver coupled to the downlink antenna 412 receives transmissions over the wireless transmission link 450 at the same time as the uplink transmitter coupled to the uplink antenna 432. In some embodiments, there is tight time synchronization with minimal guard times between changes in duplex direction.

[0109] The UE transceiver 430 and the base station transceiver 410 are configured to communicate via a wireless data communication link 450 and cooperate with an appropriately configured RF antenna arrangement 412 / 432 that can support a specific wireless communication protocol and modulation scheme. In some illustrative embodiments, the UE transceiver 410 and the base station transceiver 410 are configured to support industry standards such as long-term evolution (LTE) and emerging 5G standards. However, it should be understood that the present disclosure is not necessarily limited to the application of specific standards and related protocols. On the contrary, the UE transceiver 430 and the base station transceiver 410 can be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0110] According to various embodiments, for example, BS 402 may be an evolved Node B (eNB), a serving eNB, a target eNB, a femtocell or a microcell.

[0114] 2. Overview of non-terrestrial networks

[0115] Figure 5 5 is a block diagram illustrating an example non-terrestrial network 500 based on transparent payload according to an embodiment of the present disclosure. The non-terrestrial network 500 may include a UE 304, a BS 302, and / or a satellite 506. The non-terrestrial network 500 may include a gateway 508 for connecting the non-terrestrial network 500 to a data network 510 (e.g., public or private). A feeder link 512 connects the satellite 506 to the gateway 508. A service link 514 connects the satellite 506 to the UE 504.

[0116] In some embodiments, BS 302 may be located on the earth near (e.g., close to, adjacent to) gateway 508. In some embodiments, the beam coverage area may be a cell that is larger than a cell of non-terrestrial network 500. In some embodiments, the transparent payload may include radio frequency filtering, frequency conversion, and / or amplification; thus, the waveform signal repeated by the payload may not be altered.

[0117] Figure 6 6 is a block diagram describing an example non-terrestrial network 600 based on a regenerative payload according to an embodiment of the present disclosure. The non-terrestrial network 600 may include a UE 304, a BS 302, and / or a satellite 606. The non-terrestrial network 600 may include a gateway 608 for connecting the non-terrestrial network 600 to a data network 610 (e.g., public or private). A feeder link 612 connects the satellite 606 to the gateway 608. A service link 614 connects the satellite 606 to the UE 604. In some embodiments, the BS 302 may be located on the satellite 606. An inter-satellite link (ISL) 616 connects the satellite 606 to the UE 604. In some embodiments, the BS 302 may be located on the satellite 606. In some embodiments, the beam coverage area may be a cell that is larger than a cell of the non-terrestrial network 600. In some embodiments, the regenerative payload may include RF filtering, frequency conversion, amplification; demodulation / decoding, switching and / or routing and / or coding / modulation; thus, all or part of the base station functions (e.g., Figure 3 BS 302 in ( ) can be on a satellite 606 or UAS platform. In some embodiments, non-terrestrial network 600 may include a constellation of LEO and / or MEO. In some embodiments, LEO includes an orbit around the earth with an altitude between 300 kilometers and 1500 kilometers. In some embodiments, MEO includes a region of space around the earth above LEO and below geostationary earth orbit (GEO).

[0118] Still reference Figure 5 and Figure 6 , satellite 506 and / or satellite 606 can be a geostationary (GEO) satellite or a non-GEO satellite. GEO satellites can be fed by one or more gateways (e.g., gateway 508, gateway 608), which can be deployed within the satellite's target coverage (e.g., regional or even continental coverage). In some embodiments, a UE in a cell is served by only one gateway. Non-GEO satellites can be served continuously by one or more gateways (e.g., gateway 508, gateway 608) at a time; thereby ensuring the continuity of the service link and the feed link between the continuously serving gateways, with sufficient duration for mobility anchoring and handover. In some embodiments, one or more GEO satellites and / or one or more UAS can be used to provide continental, regional and / or local services.

[0119] Satellite 506 and / or satellite 606 or UAS platform may implement transparent or regenerative (e.g., with onboard processing) payloads.

In some embodiments, the coverage area of ​​the beam may be elliptical. The field of view of satellite 506 and / or satellite 606 or UAS platform may depend on the onboard antenna pattern and / or minimum elevation angle.

[0120] In some embodiments, a constellation of LEOs and / or MEOs may be used to provide services in the northern and southern hemispheres. In some embodiments, a constellation may provide global coverage including polar regions.

[0121] 3. Overview of UE capabilities

[0122] Figure 7 700 is a flow chart of an example transmission of a UE capability report according to a conventional embodiment. Figure 7 302” in the figure). In some embodiments, BS 302 may obtain UE 304 capabilities by sending a UECapabilityEnquiry message to UE 304, which causes UE 304 to send a UECapabilityInformation message (sometimes referred to as a “UE capability report”) to BS 302. In some embodiments, the UECapabilityInformation message may include parameters of the capabilities of UE 304. In some embodiments, the UECapabilityInformation message does not include the polarizations supported by UE 304.

[0123] Figure 8 800 is a block diagram of an example environment for a 5G NR synchronization signal block (SSB) according to a conventional embodiment. As shown in environment 800, multiple SSBs may be transmitted by BS 302 on the same frequency band, using different beams, and / or at different time intervals. In some embodiments, a master information block (MIB) in each SSB may indicate a frequency-time location of a system information block 1 (SIB1). SIB1 provides information about the BWP configuration. However, in the conventional embodiment shown in environment 800, polarization information is not included in the information provided by SIB1.

[0124] 4. Using polarization information to improve resource switching efficiency

[0125] If polarization is used in the resource reuse scheme, the polarization information of adjacent beams (e.g., LHCP, RHCP, linear polarization, cross linear polarization, etc.) may be useful in beam switching. In some NTN scenarios (e.g., LEO, HAPS), vehicle-mounted BSs (e.g., Figure 3 The BS 302 in the UE may move at high speed, which means that even for fixed UEs on the ground, frequent beam switching is required. In this case, the known polarization of the target beam can help the UE (e.g., Figure 3 UE 304 in ) completes its beam switching faster.

[0126] 4.1 Case 1: Using broadcast polarization information

[0127] Impact on UE:

[0128] To facilitate beam switching without blindly trying a target beam polarization, in some embodiments, the UE 304 may monitor (eg, observe, track, manage, monitor, etc.) broadcast polarization information from the serving beam.

[0129] BS side impact:

[0130] Fig.9A A block diagram of an example frequency reuse scheme with a 1-N mapping between cells and SSBs according to some embodiments of the present disclosure is shown. As shown, the frequency reuse scheme 900A includes a cell 0 (corresponding to PCI0) mapped (e.g., linked, associated, grouped, etc.) to multiple SSBs, where each SSB corresponds to a frequency and / or polarization capability (sometimes referred to as "polarization information"). That is, a first frequency (e.g., F0) can be reused across a first group of SSBs (e.g., SSB0, SSB2, SSB4, SSB6, SSB8, SSB10, SSB12, and SSB14), and a second frequency (e.g., F1) can be reused across a second group of SSBs (e.g., SSB1, SSB3, SSB5, SSB7, SSB9, SSB11, SSB13, and SSB15). The first polarization capability (e.g., LHCP) may correspond to a third group of SSBs (e.g., SSB0, SSB1, SSB2, SSB3, SSB8, SSB9, SSB10, and SSB11), and the second polarization capability (e.g., RHCP) may correspond to a fourth group of SSBs (e.g., SSB4, SSB5, SSB6, SSB7, SSB12, SSB13, SSB14, and SSB15). In some embodiments, one or two frequencies (e.g., F0 and F1) may be different in order to reduce interference between cells. Although Fig.9AOnly the frequency reuse scheme of one cell mapped to a selected number of SSBs, frequencies, and polarization capabilities is shown, but any number of SSBs, frequencies, and polarization capabilities may be used.

[0131] Fig. 9B According to some embodiments of the present disclosure, Fig.9A Block diagram of an example environment for BWPs for each SSB in a frequency reuse scheme 900A. If a 1 to N mapping between cells and SSBs is used, beam switching may occur within the coverage of the same cell. Therefore, cell-level switching may be reduced, which is desirable from the perspective of higher layer signaling savings and resource switching efficiency.

[0132] In some embodiments, the frequency / polarization of each beam may be different in a given cell. Fig. 9B As shown, the SSB index has been marked as an example. In this example, two BWPs can be used to achieve frequency reuse. In some embodiments, the frequency resources of SSB and BWP0 / BWP1 can be different. In some embodiments, the MIB in each SSB indicates the frequency-time position of SIB1. In some embodiments, SIB1 gives information about the BWP configuration.

[0133] 4.1.1 Example 1-a: SSB resources with the same frequency and different polarizations

[0134] Still reference Fig. 9B In some embodiments, multiple SSBs may be broadcast in the same frequency resource using time domain multiplexing. In different beam coverages, in some embodiments, the same frequency resource may be reserved for SSB broadcasts. In different beam coverages, in some embodiments, transmissions other than SSBs may use different frequency resources depending on the beam deployment. In some embodiments, the polarization of the SSB transmission may be the same as other transmissions in a given beam. After successfully decoding the SSB, in some embodiments, a UE 304 on the ground (e.g., assumed stationary for simplicity) may know the polarization and / or frequency-time position of the SIB1 of the corresponding beam. As the vehicle-mounted BS 302 moves, in some embodiments, another beam will cover the UE 304. If the polarization of an adjacent beam can be notified to the UE 304, then in some embodiments, the UE 304 does not need to blindly try possible polarizations of the SSB of the future beam in its measurements. Since the beam switching caused by the mobile vehicle-mounted BS 302 affects all UEs 304 in a given geographic area, in some embodiments, the polarization of the adjacent beam may be broadcast (e.g., in SIBx). To save signaling overhead, in some embodiments, polarization may also be bundled with the SSB index (eg, grouped, linked, associated, etc.), which may be expressed using a formula known to both BS 302 and UE 304.

[0135] Fig.10 An example mapping rule table between a cell identifier / SSB index / beam index / BWP index and polarization according to an embodiment of the present disclosure is shown. In some embodiments, the mapping rule described in Table 1000 may be a configuration information element in handover signaling, MIB, and / or SIBx.

[0136] 4.1.2 Example 1-b: SSB resources with the same frequency and the same polarization

[0137] Still reference Fig. 9B In some embodiments, multiple SSBs may be broadcast in the same frequency resource using time domain multiplexing. In different beam coverages, in some embodiments, the same frequency resources are reserved for SSB broadcasts. In different beam coverages, in some embodiments, transmissions other than SSBs may use different frequency resources depending on the beam deployment. In some embodiments, the polarization of all SSBs is the same. In some embodiments, the benefit may be that the UE 304 may decode different SSBs using fixed polarization and frequency resources. As a result, in some embodiments, the polarization of a given SSB may be different from the polarization used by other transmissions in its corresponding beam. After successfully decoding the SSB, in some embodiments, the UE 304 on the ground (assuming stationary for simplicity) knows the frequency-time location of the SIB1 of the corresponding beam, but does not know the polarization of the SIB1. If the polarization of the beam can be notified to the UE 304, then in some embodiments, the UE 304 does not need to blindly try possible polarizations, and processing time and power can be saved. Since the polarization of the beam affects all UEs 304 in a given geographic area, in some embodiments, the polarization of the beam should be broadcast (e.g., in the MIB). To save signaling overhead, in some embodiments, polarization may also be bundled with the SSB index, which may be represented using a formula known to both BS 302 and UE 304.

[0138] As mentioned above, Fig.10 An example mapping rule table between a cell identifier / SSB index / beam index / BWP index and polarization according to an embodiment of the present disclosure is shown. In some embodiments, the mapping rule described in Table 1000 may be a configuration information element in handover signaling, MIB, and / or SIBx.

[0139] 4.2 Case 2: Frequency resources and / or polarization information with broadcast

[0140] Impact on UE:

[0141] To facilitate beam switching without blindly trying a target beam polarization, in some embodiments, the UE 304 may monitor (eg, observe, track, manage, monitor, etc.) broadcast polarization information from the serving beam.

[0142] BS side impact:

[0143] Fig.11 According to some embodiments of the present disclosure, Fig.9A Block diagram of an example environment for SSBs on different frequency resources in a frequency reuse scheme 900A. If a 1 to N mapping between cells and SSBs is used, beam switching may occur within the coverage of the same cell. Therefore, cell-level switching may be reduced, which is desirable from the perspective of higher layer signaling savings and resource switching efficiency.

[0144] 4.2.1 Example 2-a: SSB resource with polarization

[0145] Within a given beam coverage, in some embodiments, SSB and other transmissions can use the same frequency resources based on the beam deployment. For example, Fig.11 Two groups of SSBs are shown, where group 0 includes SSB0 / 2 / 4 / 6 and group 1 includes SSB1 / 3 / 5 / 7. Thus, in some embodiments, the SSBs are located in the same frequency resources as other transmissions in a given beam. In some embodiments, the polarization of the SSBs in a group may be the same (e.g., SSB0 / 2 / 4 / 6 use LHCP). As a result, in some embodiments, the polarization of a given SSB may be different from the polarization used by other transmissions in its corresponding beam (e.g., RHCP is used in the beam corresponding to SSB4 / 6). After successfully decoding the SSB, in some embodiments, a UE 304 on the ground (assumed stationary for simplicity) knows the frequency-time location of the SIB1 of the corresponding beam, but does not know the polarization of the SIB1. If the polarization of the beam can be notified to the UE 304, then in some embodiments, the UE 304 does not need to blindly try possible polarizations, and processing time and power can be saved. Since the polarization of a beam can affect all UEs in a given geographic area, in some embodiments, the polarization of the beam can be broadcast (e.g., in the MIB). To save signaling overhead, in some embodiments, polarization may also be bundled with the SSB index, which may be represented using a formula known to both BS 302 and UE 304.

[0146] As mentioned above, Fig.10 An example mapping rule table between a cell identifier / SSB index / beam index / BWP index and polarization according to an embodiment of the present disclosure is shown. In some embodiments, the mapping rule described in Table 1000 may be a configuration information element in handover signaling, MIB, and / or SIBx.

[0147] 4.2.2 Example 2-b: SSB group resources with different polarizations

[0148] Within a given beam coverage, in some embodiments, SSB and other transmissions can use the same frequency resources based on the beam deployment. For example, Fig.11 Two sets of SSBs are shown, with the SSBs broadcast in different frequency resources with possible time domain multiplexing. In some embodiments, the polarization of the SSB can be the same as the polarization used by other transmissions in its corresponding beam (e.g., SSB0 / 1 / 2 / 3 and other transmissions in the corresponding beam all use LHCP). After successfully decoding the SSB, in some embodiments, the UE 304 on the ground (assumed stationary for simplicity) knows the frequency-time location and polarization of SIB1 of the corresponding beam. As the vehicular BS moves, in some embodiments, another beam will cover the UE 304. If the polarization of an adjacent beam can be notified to the UE 304, then in some embodiments, the UE 304 does not need to blindly try possible polarizations of SSBs for future beams in its measurements. Since the beam switching caused by the mobile vehicular BS affects all UEs 304 in a given geographic area, in some embodiments, the polarization of the adjacent beam can be broadcast (e.g., in SIBx). To save signaling overhead, in some embodiments, polarization may also be bundled with the SSB index, which may be represented using a formula known to both BS 302 and UE 304.

[0149] As mentioned above, Fig.10 An example mapping rule table between a cell identifier / SSB index / beam index / BWP index and polarization according to an embodiment of the present disclosure is shown. In some embodiments, the mapping rule described in Table 1000 may be a configuration information element in handover signaling, MIB, and / or SIBx.

[0150] 5. Using polarization information to support UEs with limited polarization capabilities

[0151] In some embodiments, some UEs 304 may have limited polarization capabilities (e.g., only LHCP or only RHCP). To support UEs 304 with limited polarization capabilities, in some embodiments, BS 302 may use time division duplexing (TDD) to cover an area with LHCP or RHCP at a given time. In this case, in some embodiments, UE 304 may notify (e.g., inform, alert, etc.) BS 302 of its polarization capabilities. That is, UE 304 may send a message to BS 302 indicating the polarization capabilities of UE 304.

[0152] 5.1 Case 3: Supporting UE with limited polarization capability

[0153] Impact on UE:

[0154] To facilitate BS scheduling, in some embodiments, UE 304 may inform BS 302 of its polarization capabilities, which may include, for example, information indicating linear polarization, cross-linear polarization, left-hand circular polarization (LHCP) and / or right-hand circular polarization (RHCP). In addition, in some embodiments, the polarization capabilities in the transmit direction, the receive direction, or both directions may be indicated. In some embodiments, the polarization capabilities may be reported to BS 302 using a UECapabilityInformation message, i.e., the polarization capabilities (as discussed herein) are added to the UE-NR-Capability information element.

[0155] BS side impact:

[0156] If the BS 302 has information about the polarization capabilities of the UEs, it can, in some embodiments, group the UEs 302 according to their polarization capabilities. In some embodiments, time division duplexing (TDD) at the BS 302 can be used to serve UEs 302 with different polarization capabilities in a given spot beam. For example, the BS 302 can indicate additional TDD periods to LHCP-only UEs 304 to enable semi-static persistent (SSP) DL / UL grants. As another example, the BS 302 can indicate additional TDD periods to LHCP-only UEs to enable periodic interruptions in repetition-based transmissions.

[0157] 6. Using polarization information to improve network performance

[0158] If polarization is not used in the resource reuse scheme in some embodiments, it can be used as an additional diversity dimension to improve network performance. For example, polarization can be used for interference mitigation.

[0159] 6.1 Case 4: Interference Mitigation under Polarization Reuse

[0160] Impact on UE:

[0161] To facilitate interference mitigation using polarization isolation, in some embodiments, UE 304 may inform BS 302 of its polarization capabilities, which may include, for example, information indicating linear polarization, cross-linear polarization, left-hand circular polarization (LHCP), and / or right-hand circular polarization (RHCP). In addition, in some embodiments, the polarization capabilities in the transmit direction, the receive direction, or both directions may be indicated. In some embodiments, the polarization capabilities may be reported to BS 302 using a UECapabilityInformation message, i.e., the polarization capabilities (as discussed herein) are added to the UE-NR-Capability information element.

[0162] BS side impact:

[0163] If BS 302 has information about the polarization capabilities of UE 304, it can use this information to mitigate interference in some embodiments. In addition, in some embodiments, time, frequency, spatial isolation and / or polarization can be used as another isolation dimension. Therefore, in some embodiments, BS 302 can indicate the circular polarization direction used by the UE in UL / DL transmissions.

[0164] After UE 304 receives an indication to change its polarization from BS 302, in some embodiments, BS 302 may allow a time interval before the UE's polarization change takes effect. In some embodiments, the length of the time interval may be related to round-trip propagation delay and / or processing delay on the UE 304 and / or BS 302 side.

[0165] In some embodiments, the polarization capability indicates that UE 304 supports only a single polarization (RHCP only or LHCP only), which is the same polarization reported in the polarization capability that is expected to be used by UE 304 for communication between UE 304 and BS 302 (uplink and downlink).
