[0003] open field

[0004] Various aspects of this disclosure generally relate to wireless communication, and to techniques and apparatus for polarization indication signaling. Background Technology

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0006] A wireless network may include one or more base stations that support communication for one or more user equipment (UEs). UEs may communicate with base stations via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the base station to the UE, while "uplink" (or "UL") refers to the communication link from the UE to the base station.

[0007] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is an enhancement set to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink, CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to grow.

[0045] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims.

[0046] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0047] While the aspects herein may be described using terms commonly associated with 5G or New Radio (NR) Radio Access Technology (RAT), the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0048] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE) network) network, or may include elements thereof. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), one or more user equipment (UE) 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. Base station 110 is the entity that communicates with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a B-node, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit / receive point (TRP). Each base station 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of ​​base station 110 and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0049] Base station 110 provides communication coverage to macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UE 120 with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UE 120 with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UE 120 associated with that femtocell (e.g., UE 120 in a closed subscriber group (CSG)). Base station 110 for macrocells may be referred to as a macro base station. Base station 110 for picocells may be referred to as a pico base station. Base station 110 for femtocells may be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS 110a can be a macro base station for macro cell 102a, BS 110b can be a pico base station for pico cell 102b, and BS 110c can be a femto base station (BS) for femtocell 102c. A base station may support one or more (e.g., three) cells.

[0050] In some examples, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base stations 110 may interconnect with each other and / or interconnect to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0051] Wireless network 100 may include one or more relay stations. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., base station 110 or UE 120) and transmitting those data transmissions to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 capable of relaying transmissions for other UE 120s. Figure 1 In the example shown, BS 110d (e.g., a relay base station) can communicate with BS 110a (e.g., a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. The base station 110 for relay communication may be referred to as a relay station, relay base station, relay, etc.

[0052] Wireless network 100 can be a heterogeneous network comprising different types of base stations 110 (such as macro base stations, pico base stations, femto base stations, or relay base stations, etc.). These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro base stations may have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0053] Network controller 130 can be coupled to or communicate with a group of base stations 110 and can provide coordination and control over these base stations 110. Network controller 130 can communicate with base stations 110 via backhaul communication links. Base stations 110 can communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0054] Each UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), an in-vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via a wireless medium.

[0055] Some UEs 120 may be considered Machine-Type Communication (MTC) UEs, or evolved or enhanced Machine-Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which can communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered client equipment. UE 120 may be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0056] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0057] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0058] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., according to frequency or wavelength. For example, each device in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410 MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is generally (interchangeably) referred to as the “sub-6 GHz” band in various documents and articles. Similar naming issues sometimes arise regarding FR2; although different from the Very High Frequency (EHF) band (30 GHz – 300 GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is generally (interchangeably) referred to as the “millimeter wave” band in various documents and articles.

[0059] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have identified the operating bands of these IF bands as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 into the IF band. Additionally, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating frequency bands have been identified as the frequency range designations FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0060] Considering the examples above, unless otherwise stated, it should be understood that, as used herein, the term "sub-6 GHz," etc., can broadly refer to frequencies less than 6 GHz, within FR1, or that may include intermediate frequency band frequencies. Furthermore, unless otherwise stated, it should be understood that, as used herein, the term "millimeter wave," etc., can broadly refer to frequencies that may include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0061] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0062] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to this disclosure. The base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0063] At base station 110, transmit processor 220 can receive data from data source 212 intended for UE 120 (or a group of UEs 120). Transmit processor 220 can select one or more modulation and coding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Base station 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the selected MCS(s) for UE 120, and can provide data symbols to UE 120. Transmit processor 220 can process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or higher-layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 can generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modulators) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use the corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a downlink signal. Modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0064] At UE 120, an antenna set 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110 and can provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on these received symbols where applicable, and can provide detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.

[0065] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in the core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0066] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more antenna element assemblies, and / or one or more antenna arrays, etc., or may be included therein. Antenna panels, antenna groups, antenna element assemblies, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), coplanar antenna element assemblies, non-coplanar antenna element assemblies, and / or coupled to one or more transmit and / or receive components (such as...) Figure 2 One or more antenna elements (one or more components).

[0067] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). Transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from transmit processor 264 may be pre-encoded by TX MIMO processor 266 where applicable, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, modem 254 of UE 120 may include modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modems 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., references). Figure 6 -14).

[0068] At base station 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antennas 234, modems 232, MIMO detectors 236, receiver processors 238, transmitter processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., references). Figure 6 -14).

[0069] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component may perform one or more techniques associated with polarization indication signaling, as described in more detail elsewhere herein.

For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly executed, or executed after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or base station 110 may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example...

[0070] In some aspects, a base station (e.g., base station 110) may include: means for determining polarization for a portion of a bandwidth; and / or means for transmitting a polarization indication to user equipment indicating the polarization for that portion of the bandwidth. In some aspects, such means may include a combination of Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receiver processor 238, controller / processor 240, transmitter processor 220, TX MIMO processor 230, MOD 232 and / or antenna 234.

[0072] In some aspects, a base station (e.g., base station 110) may include: means for determining a polarization relationship between a source transmission and a target transmission with respect to the base station and user equipment; and / or means for transmitting to the user equipment a quasi-co-location instance indicating the polarization relationship between the source transmission and the target transmission.

[0073] In some aspects, the UE (e.g., UE 120) may include: means for receiving from a base station a polarization indication indicating polarization for a portion of the bandwidth; and / or means for performing communication with the base station at least in part based on the polarization for that portion of the bandwidth. In some aspects, such means may include a combination of Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, and / or receive processor 258.

[0074] In some aspects, the UE (e.g., UE 120) may include: means for receiving from a base station a configuration indicating the polarization of a transmission; and / or means for processing the transmission at least in part based on the polarization of the transmission. In some aspects, such means may include a combination of Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, and / or receive processor 258.

[0075] In some aspects, the UE (e.g., UE 120) may include: means for receiving from a base station a quasi-co-location instance indicating a polarization relationship between a source transmission and a target transmission; and / or means for performing communication with the base station at least in part based on the polarization relationship. In some aspects, such means may include a combination of Figure 2One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, and / or receive processor 258.

[0076] although Figure 2 The boxes in the diagram are interpreted as different components, but the functions described above with respect to these boxes can be implemented using a single hardware component, software component, or combination of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of controller / processor 280.

[0077] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0078] Figure 3 These are illustrations illustrating Example 300 of regenerative satellite deployment and Example 310 of transparent satellite deployment in a non-terrestrial network according to this disclosure.

[0079] Example 300 illustrates a regenerative satellite deployment. In Example 300, UE 120 is served by satellite 320 via serving link 330. For example, satellite 320 may include BS 110 (e.g., BS 110a) and / or gNB. In some aspects, satellite 320 may be referred to as a non-terrestrial base station, a regenerative repeater, an onboard processing repeater, and / or a non-terrestrial network entity. In some aspects, satellite 320 may demodulate uplink radio frequency signals and may modulate baseband signals derived from uplink radio signals to generate downlink radio frequency transmissions. Satellite 320 may transmit downlink radio frequency signals over serving link 330. Satellite 320 may provide cellular coverage for UE 120.

[0080] Example 310 illustrates a transparent satellite deployment, which may also be referred to as a bend-tube satellite deployment. In Example 310, UE 120 is served by satellite 340 via serving link 330. Satellite 340 may be a transparent satellite. Satellite 340 may relay signals received from gateway 350 via feeder link 360. For example, the satellite may receive uplink RF transmissions and may transmit downlink RF transmissions without demodulating the uplink RF transmissions. In some aspects, the satellite may convert the uplink RF transmission frequency received on serving link 330 to the uplink RF transmission frequency on feeder link 360, and may amplify and / or filter the uplink RF transmissions. In some aspects, UE 120 shown in Examples 300 and 310 may be associated with Global Navigation Satellite System (GNSS) capability and / or Global Positioning System (GSP) capability, but not all UEs have such capabilities. Satellite 340 may provide cellular coverage for UE 120.

[0081] Service link 330 may include a link between satellite 340 and UE 120, and may include one or more of an uplink or a downlink. Feeder link 360 may include a link between satellite 340 and gateway 350, and may include one or more of an uplink (e.g., from UE 120 to gateway 350) or a downlink (e.g., from gateway 350 to UE 120).

[0082] Due to the movement of satellites 320 and 340, and the potential movement of UE 120, feeder link 360 and service link 330 may each experience Doppler effects. These Doppler effects may be significantly greater than those in terrestrial networks. The Doppler effects on feeder link 360 can be compensated for to some extent, but may still be associated with a certain amount of uncompensated frequency error. Furthermore, gateway 350 may be associated with residual frequency errors, and / or satellites 320 / 340 may be associated with onboard frequency errors. These sources of frequency errors may cause the downlink frequency received at UE 120 to deviate from the target downlink frequency.

[0083] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0084] Figure 4 This is a diagram illustrating example 400 of linear polarization and circular polarization according to this disclosure.

[0085] Linear polarization occurs when the tip of the electric field of an electromagnetic wave at a fixed point in space oscillates linearly with time. Circular polarization occurs when the tip of the electric field of an electromagnetic wave at a fixed point in space moves around a circle. Furthermore, electromagnetic waves can be formed by superimposing two orthogonal linearly polarized waves of equal amplitude and with a 90-degree phase difference.

[0086] As indicated above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0087] Figure 5 This is a diagram illustrating example 500 of a coverage area served by one or more polarizations according to this disclosure.

[0088] As indicated by label 502, a coverage area can be served by a single polarization to increase system capacity. When a coverage area is associated with a sparse UE constellation, a single polarization for that coverage area may be beneficial, where the UE can dynamically adjust the polarization. This polarization can be circular, such as right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP), or it can be linear, such as vertical linear polarization or horizontal linear polarization.

[0089] As indicated by label 504, a coverage area can be served by two polarizations to increase system capacity. These two polarizations can be associated with the same frequency or with different frequencies. Two polarizations may be beneficial when the coverage area is associated with a dense UE constellation. These two polarizations can be circular or linear.

[0090] As indicated above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 The example described.

[0091] Transmit polarization can refer to the polarization associated with a transmission from a base station or UE, and receive polarization can refer to the polarization associated with a reception at a base station or UE. In some cases, transmit polarization can be the same as receive polarization. However, in other cases, transmit polarization can differ from receive polarization, which can lead to polarization mismatch loss. For example, when the transmit polarization is RHCP and the receive polarization is LHCP, the polarization mismatch loss may be greater than 20 dB. When the transmit polarization is circular and the receive polarization is linear or inverse, the polarization mismatch loss may be approximately 3 dB. When the transmit polarization is horizontal linear and the receive polarization is vertical linear, the polarization mismatch loss may be greater than 20 dB.

[0092] Portable devices (such as UEs) may have varying polarizations due to mobility. Furthermore, regarding frequency reuse, linear polarization (e.g., horizontal or vertical linear polarization) may not be less reliable for portable devices. Frequency reuse can occur when a specified range of frequencies is used more than once within the same radio system, thus increasing the overall capacity of the radio system without increasing its allocated bandwidth.

[0093] A UE with polarization capability can detect polarization and / or use that polarization to transmit signals. For example, a UE capable of two circular polarization modes can detect the circular polarization associated with one of those two modes. A UE with two linearly cross-polarized antennas can use both circular polarizations to detect and transmit signals.

[0094] However, polarization detection can increase processing at the UE. For example, polarization detection for signal transmission and reception with respect to circular and / or linear polarization can increase processing at the UE. Furthermore, in some cases, the UE may be unable to determine the polarization associated with signal transmission or reception.

[0095] In various aspects of the technologies and apparatus described herein, polarization indication signaling can be configured by the base station to indicate polarization to the UE. In some aspects, polarization indication signaling can indicate polarization associated with a bandwidth portion. In some aspects, polarization indication signaling can indicate the polarization relationship between source and destination transmissions between the base station and the UE. In some aspects, polarization indication signaling can indicate polarization associated with downlink or uplink transmissions. This polarization indication signaling can avoid polarization mismatch losses at the UE, which may occur when the UE cannot detect the polarization and a mismatch occurs between transmit and receive polarizations. Even when the UE can detect the polarization, polarization indication signaling can reduce the amount of processing occurring at the UE.

[0096] In some respects, for line-of-sight signal propagation, polarization indication signaling can avoid polarization detection at the UE. In other respects, polarization indication signaling can also be useful to the UE for non-line-of-sight and near-line-of-sight signal propagation. For example, polarization indication signaling can enable the UE to determine the polarization of a first beam and a second beam, and whether the polarizations of the first and second beams are the same or different. For the downlink, the receive polarization may differ from the transmit polarization. For the uplink, assuming the downlink and uplink are reciprocal (e.g., the uplink and downlink are relatively close in frequency), the transmit polarization can correspond to the receive polarization. For both the downlink and uplink, polarization indication signaling can enable the UE to determine the transmit and receive polarizations, where the transmit and receive polarizations can be the "optimal" transmit and receive polarizations compared to other transmit and receive polarizations that may be used at the UE and / or base station.

[0097] Figure 6 This is a diagram illustrating Example 600 associated with polarization indication signaling according to this disclosure. (See diagram for example.) Figure 6 As shown, Example 600 includes communication between a base station (e.g., base station 110) and a UE (e.g., UE 120). In some aspects, the base station and the UE may be included in a wireless network (such as wireless network 100). The base station and the UE may communicate on a wireless sidelink.

[0098] As shown by reference numeral 602 in the attached figure, the base station can determine the polarization of a bandwidth portion. In some aspects, polarization can be predefined for a specific bandwidth portion. For example, for a specific bandwidth portion, the polarization can be RHCP, LHCP, vertical linear polarization, and / or horizontal linear polarization.

[0099] In some respects, the polarization of a bandwidth portion can be based at least in part on the polarization of a reference signal associated with that bandwidth portion, such as a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS). For example, the polarization of the bandwidth portion can correspond to the polarization of the SSB or the CSI-RS, or the polarization of the bandwidth portion can be orthogonal to the polarization of the SSB or the CSI-RS.

[0100] In some respects, a first polarization may be associated with a first bandwidth portion, and a second polarization may be associated with a second bandwidth portion. Switching between the first and second bandwidth portions may involve switching between the first and second polarizations. In other words, polarization switching can be part of bandwidth portion switching.

[0101] In some aspects, the polarization of a bandwidth portion can be the default polarization of multiple transmissions (e.g., all transmissions) associated with that bandwidth portion. In some aspects, when the bandwidth portion is a downlink bandwidth portion, its polarization can be the default polarization of Physical Downlink Shared Channel (PDSCH) transmissions or Physical Downlink Control Channel (PDCCH) transmissions. In some aspects, when the bandwidth portion is a downlink bandwidth portion, its polarization can be the default polarization of the control resource set. In some aspects, when the bandwidth portion is an uplink bandwidth portion, its polarization can be the default polarization of Physical Uplink Shared Channel (PUSCH) transmissions or Physical Uplink Control Channel (PUCCH) transmissions.

[0102] In some aspects, when downlink transmissions (e.g., PDCCH or PDSCH transmissions) are configured in a bandwidth portion, the polarization of the downlink transmissions can correspond to the polarization of that bandwidth portion. Similarly, in some aspects, when uplink transmissions (e.g., PUCCH or PUSCH transmissions) are configured in a bandwidth portion, the polarization of the uplink transmissions can correspond to the polarization of that bandwidth portion.

[0103] As shown by reference numeral 604 in the attached figure, the base station may transmit a polarization indication to the UE that indicates the polarization for a bandwidth portion. In some aspects, the polarization may explicitly indicate the polarization for that bandwidth portion (e.g., RHCP, LHCP). In other aspects, the polarization indication may indicate the polarization for that bandwidth portion based at least in part on the polarization of a reference signal (e.g., SSB, CSI-RS) associated with the bandwidth portion.

[0104] As shown by reference numeral 606 in the accompanying drawings, the UE may perform communication with the base station at least in part based on the polarization for that bandwidth portion (as indicated in the polarization indication). For example, the UE may receive a polarization indication indicating the polarization for that bandwidth portion, and the UE may perform transmissions in that bandwidth portion at least in part based on the polarization associated with that bandwidth portion.

[0105] As indicated above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 The example described.

[0106] Figure 7 This is a diagram illustrating Example 700 associated with polarization indication signaling according to this disclosure. (See diagram for example.) Figure 7 As shown, Example 700 includes communication between a base station (e.g., base station 110) and a UE (e.g., UE 120). In some aspects, the base station and the UE may be included in a wireless network (such as wireless network 100). The base station and the UE may communicate on a wireless sidelink.

[0107] As shown by reference numeral 702 in the attached figure, the base station can determine the polarization of a transmission (such as a downlink transmission or an uplink transmission). The polarization of a downlink or uplink transmission can be RHCP, LHCP, vertical linear polarization, and / or horizontal linear polarization. Downlink transmissions can be PDCCH transmissions and / or PDSCH transmissions. Uplink transmissions can be PUCCH transmissions and / or PUSCH transmissions. In some respects, the same polarization can be applied to multiple types of downlink or uplink transmissions (e.g., the polarization of a PDSCH transmission can correspond to the polarization of a PDCCH transmission).

[0108] As shown by reference numeral 704 in the accompanying drawings, the base station may transmit to the UE a configuration indicating the polarization of the transmission (e.g., a downlink transmission or an uplink transmission). When the transmission corresponds to a downlink transmission, the configuration may be a downlink configuration; or when the transmission corresponds to an uplink transmission, the configuration may be an uplink configuration. In some aspects, the downlink configuration may be associated with a control resource set configuration and / or a search space configuration.

[0109] In some respects, the downlink configuration may indicate the polarization relationship between downlink transmissions and reference signals (e.g., SSB or CSI-RS), and the UE may deduce the polarization of the downlink transmissions at least in part based on the polarization relationship indicated in the downlink configuration. This polarization relationship may be a parameter included in the Transport Configuration Indicator (TCI) state, which may be part of the downlink configuration transmitted from the base station to the UE.

[0110] In some respects, the downlink configuration can explicitly indicate the polarization associated with the downlink transmission. The polarization associated with the downlink transmission can correspond to the polarization associated with a reference signal (e.g., SSB or CSI-RS), or the polarization associated with the downlink transmission can be different from (e.g., orthogonal to) the polarization associated with the reference signal.

[0111] In some aspects, downlink configuration may be included in downlink control information (DCI), media access control-control element (MAC-CE), or radio resource control (RRC) messages. The downlink configuration included in a DCI, MAC-CE, or RRC message may include a defined number of bits to indicate the polarization of the downlink transmission. For example, when a bit is used to indicate the polarization of the downlink transmission, a first value of the bit (e.g., 0) may indicate a first type of polarization (e.g., LHCP), and a second value of the bit (e.g., 1) may indicate a second type of polarization (e.g., RHCP). In some aspects, the indication of the polarization of the downlink transmission may be considered as an allocation of the downlink transmission polarization.

[0112] In some respects, the uplink configuration can indicate the polarization relationship between the uplink transmission and a reference signal (such as an SSB, CSI-RS, or Probe Reference Signal (SRS)). The UE can deduce the polarization of the uplink transmission based at least in part on the polarization relationship indicated in the uplink configuration. This polarization relationship can be a parameter included in the TCI state, which can be part of the uplink configuration transmitted from the base station to the UE. The polarization associated with the uplink transmission can correspond to the polarization associated with the reference signal (e.g., SSB, CSI-RS, or SRS), or the polarization associated with the uplink transmission can be different from (e.g., orthogonal to) the polarization associated with the reference signal.

[0113] As an example, when the reference signal is an SSB associated with RHCP, the uplink configuration can indicate that the polarization of the uplink transmission is also RHCP. As another example, when the reference signal is a CSI-RS associated with LHCP, the uplink configuration can indicate that the polarization of the uplink transmission is RHCP.

[0114] In some aspects, uplink configuration can indicate the polarization relationship between uplink and downlink transmissions. The polarization of the uplink transmission can correspond to the polarization of the downlink transmission, or the polarization of the uplink transmission can be different from (e.g., orthogonal) to the polarization of the downlink transmission. In some aspects, the downlink transmission can be a PDCCH transmission configured with a polarization relationship to the uplink transmission. In other words, the polarization of the uplink transmission can correspond to the polarization of the PDCCH transmission.

[0115] In some respects, the uplink configuration can explicitly indicate the polarization of the uplink transmission. The uplink configuration can indicate that the polarization used for uplink transmission is RHCP, LHCP, vertical linear polarization, and / or horizontal linear polarization. The polarization of the uplink transmission can correspond to the reference polarization (or nominal polarization) associated with the reference signal, or the polarization of the uplink transmission can be different from the reference polarization (e.g., orthogonal).

[0116] In some aspects, uplink configuration may be included in DCI, MAC-CE, or RRC messages. Downlink configuration included in DCI, MAC-CE, or RRC messages may include a defined number of bits to indicate the polarization of uplink transmissions. For example, when a bit is used to indicate the polarization of uplink transmissions, a first value of that bit (e.g., 0) may indicate a first type of polarization (e.g., LHCP), and a second value of that bit (e.g., 1) may indicate a second type of polarization (e.g., RHCP). In some aspects, the indication of the polarization of uplink transmissions may be considered as an allocation of the polarization of uplink transmissions.

[0117] In some aspects, the uplink configuration can indicate the polarization corresponding to the polarization of the receive beam used to receive uplink transmissions. In other aspects, the uplink configuration can indicate the polarization corresponding to the expected polarization of uplink transmissions from the UE.

[0118] As shown by reference numeral 706 in the accompanying drawings, the UE may process the transmission at least in part based on the polarization of the transmission (e.g., a downlink transmission or an uplink transmission). For example, the UE may process the downlink transmission or uplink transmission at least in part based on the polarization associated with the downlink transmission or uplink transmission, as indicated by the downlink configuration or uplink configuration received from the base station.

[0119] As indicated above, Figure 7 This is provided as an example. Other examples may differ from the one provided. Figure 7 The example described.

[0120] Figure 8 This is a diagram illustrating example 800 associated with polarization indication signaling according to this disclosure. (See diagram for example.) Figure 8 As shown, Example 800 includes communication between a base station (e.g., base station 110) and a UE (e.g., UE 120). In some aspects, the base station and the UE may be included in a wireless network (such as wireless network 100).

[0121] As shown by reference numeral 802 in the attached figure, the base station can determine the polarization relationship between the source and target transmissions of the base station and the UE. The polarization relationship between the source and target transmissions can be indicated via a Quasi-Co-location (QCL) instance (or QCL type). A QCL instance can be added to the TCI state as a new QCL instance.

[0122] In some respects, the source transmission can be an SSB transmission or a CSI-RS transmission. In some respects, the destination transmission can be an SSB transmission or a CSI-RS transmission. In some respects, the destination transmission can be a transmission associated with a data channel or a control channel (e.g., a PDSCH transmission, a PDCCH transmission, a PUSCH transmission, or a PUCCH transmission).

[0123] In some aspects, the TCI state may include (e.g., QCL types A to D) to indicate the similarity between two antenna ports with respect to Doppler shift, Doppler spread, delay spread, and / or spatial receiver parameters. In some aspects, x new QCL types (e.g., QCL type E and QCL type F) may be added to the TCI state to indicate the polarization relationship between the source and target transmissions, where x is a positive integer.

[0124] In some aspects, when x equals 1, the QCL type can indicate the same polarization between the source and destination transmissions. In other words, the QCL type can indicate that the source and destination transmissions are associated with the same polarization. In some aspects, when x equals 2, a first QCL type can indicate that the source and destination transmissions are associated with the same polarization, and a second QCL type can indicate that the source and destination transmissions are associated with different (e.g., orthogonal) polarizations. In other words, the QCL type can indicate that the source and destination transmissions are associated with the same polarization or different polarizations. The polarization of the source or destination transmission can be RHCP, LHCP, vertical linear polarization, and / or horizontal linear polarization.

[0125] As an example, when the polarization of the source transmission is orthogonal to the polarization of the target transmission, the polarization of the source transmission can be LHCP and the polarization of the target transmission can be RHCP. As another example, when the polarization of the source transmission is orthogonal to the polarization of the target transmission, the polarization of the source transmission can be horizontally linear and the polarization of the target transmission can be vertically linear.

[0126] In some respects, the number of QCL instances included in the TCI state can be increased to accommodate x new QCL types indicating the polarization relationship between the source and destination transmissions. For example, the TCI state may include a first QCL instance corresponding to QCL type A, a second QCL instance corresponding to QCL type C, and a third QCL instance corresponding to QCL type E, which may indicate the polarization relationship between the source and destination transmissions (e.g., the polarization of the destination transmission is the same as the polarization of the reference signal indicated in the third QCL instance).

[0127] In some respects, existing QCL types, including those in TCI states, can be reinterpreted to indicate the polarization relationship between the source and target transmissions. For example, an existing QCL type D, which may have previously indicated space receiver parameters, can be reinterpreted to indicate the polarization relationship between the source and target transmissions.

[0128] In some respects, the polarization relationship between source and destination transmissions can be indicated at least in part based on adding new QCL types and / or QCL instances, and / or reinterpreting combinations of existing QCL types.

[0129] As shown by reference numeral 804 in the attached figure, the base station may transmit a QCL instance to the UE indicating the polarization relationship between the source transmission and the target transmission. The QCL instance may be one of multiple QCL instances included in the TCI state transmitted from the base station to the UE. In some aspects, the QCL instance may indicate that the source transmission and the target transmission are associated with the same polarization. In some aspects, the QCL instance may indicate that the source transmission and the target transmission are associated with different polarizations. In some aspects, the QCL instance may indicate that the polarization of the target transmission corresponds to the polarization of the reference signal indicated in the QCL instance.

[0130] As shown by reference numeral 806 in the attached figure, the UE can perform communication with the base station based at least in part on this polarization relationship. For example, the UE can receive a QCL instance indicating the polarization between the source transmission and the target transmission, and the UE can perform transmissions with the base station based at least in part on this polarization relationship.

[0131] As indicated above, Figure 8 This is provided as an example. Other examples may differ from the one provided. Figure 8 The example described.

[0132] Figure 9 This is a diagram illustrating an example process 900 performed by a base station according to this disclosure. Example process 900 is an example in which a base station (e.g., base station 110) performs operations associated with polarization indication signaling.
