[0002] This patent application claims priority to the following applications: U.S. Provisional Patent Application No. 63 / 047,515, filed on July 2, 2020, entitled “BANDWIDTH PART SWITCHING”; and U.S. Non-Provisional Patent Application No. 17 / 304,955, filed on June 29, 2021, entitled “BANDWIDTH PART SWITCHING”, which are expressly incorporated herein by reference. Technical Field

[0003]

[0011] Generally speaking, aspects of the disclosure relate to wireless communications and to techniques and apparatus for bandwidth fraction switching. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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 a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that can support communications for multiple user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, and an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global level. NR (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), so as to better support mobile broadband Internet access, as well as support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to grow, it is still useful to make further improvements to LTE, NR and other radio access technologies. Summary of the invention

[0025] The following is a more complete description of various aspects of the present disclosure with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and is not to be construed as being limited to any specific structure or function presented throughout the present disclosure. More specifically, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether the aspect is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect. For example, using any number of aspects set forth herein, a device can be implemented or a method can be implemented. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0026] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms, etc. (collectively referred to as "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.

[0027] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0028] Figure 1 1 is a schematic diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0029] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example of , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” may be used interchangeably.

[0030] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0031] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in , a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0032] In some aspects, the wireless network 100 may include one or more non-terrestrial network (NTN) deployments, where non-terrestrial wireless communication devices may include BSs (interchangeably referred to herein as "non-terrestrial BSs" and "non-terrestrial base stations"), relay stations (interchangeably referred to herein as "non-terrestrial relay stations"), etc. As used herein, NTN may refer to a network whose access is facilitated by non-terrestrial BSs, non-terrestrial relay stations, etc.

[0033] The wireless network 100 may include any number of non-terrestrial wireless communication devices. The non-terrestrial wireless communication devices may include satellites, unmanned aircraft systems (UAS) platforms, etc. Satellites may include low earth orbit (LEO) satellites, medium earth orbit (MEO) satellites, geostationary orbit (GEO) satellites, high elliptical orbit (HEO) satellites, etc. The UAS platform may include a high altitude platform station (HAPS), and may include balloons, airships, airplanes, etc. The non-terrestrial wireless communication device may be part of an NTN separated from the wireless network 100. Alternatively, the NTN may be part of the wireless network 100. The satellite may communicate directly and / or indirectly with other entities in the wireless network using satellite communications. Other entities may include UEs, other satellites in one or more NTN deployments, other types of BSs (e.g., fixed or ground-based BSs), relay stations, one or more components and / or devices included in the core network of the wireless network 100, etc.

[0034] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0035] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless backhaul or a wired backhaul.

[0036] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), 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 or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio unit), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0037] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or a connection to a network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component and / or a memory component). In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0038] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0039] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly with each other using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol), and / or mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0040] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) that may span from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2) that may span from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6-GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified by the International Telecommunication Union (ITU) as a “millimeter wave” band. Therefore, unless otherwise expressly stated, it should be understood that the term "sub-6 GHz", etc., if used, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the term "millimeter wave", etc., if used, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein can be applicable to those modified frequency ranges.

[0041] As indicated above, Figure 1 is provided as an example. Other examples may differ from Figure 1 The examples described are different.

[0042] Figure 22 is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0043] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively.

[0044] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMOD) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some aspects, one or more components of UE 120 may be included in housing 284.

[0045] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0046] Antennas (such as antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as Figure 2 One or more antenna elements of one or more components).

[0047] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to Figure 5-10 as described.

[0048] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit 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, for example, as described with reference to Figure 5-10 as described.

[0049] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components in the base station 110 may perform one or more techniques associated with bandwidth part (BWP) switching, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in may perform or direct e.g. Fig. 9 The process of 900 Fig.10 1000 and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Fig. 9 The process of 900 Fig.10 The operations of process 1000 and / or other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other examples.

[0050] In some aspects, the UE 120 may include: means for receiving a BWP configuration indicating one or more BWPs associated with at least one beam; means for switching from a first BWP in the one or more BWPs as an active BWP to a second BWP in the one or more BWPs as an active BWP based at least in part on the BWP configuration; and so on. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0051] In some aspects, the base station 110 may include: means for sending a BWP configuration indicating one or more BWPs associated with at least one beam to a user equipment; means for switching from a first BWP in the one or more BWPs as an active BWP to a second BWP in the one or more BWPs as an active BWP based at least in part on the BWP configuration; and so on. In some aspects, such means may include combining Figure 2One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0052] Although Figure 2 The blocks in the 200 and 210 are shown as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0053] As noted above, Figure 2 is provided as an example. Other examples may differ from those described above. Figure 2 Examples described.

[0054] Figure 3 300 and 310 are diagrams showing examples of NTN deployment. Example 300 and / or example 310 may be, similar to, include, or be included in a wireless network, such as in Figure 1 Shown and combined Figure 1 A wireless network 100 is described.

[0055] Example 300 illustrates a conceptual description of a regenerative satellite deployment. In example 300, UE 120 is served by satellite 320 via service link 330. For example, satellite 320 may include BS 110 (e.g., BS 110a), gNB, one or more functions of BS 110 (e.g., RF filtering, frequency conversion, amplification, demodulation, decoding, switching, routing, encoding, modulation, etc.), etc. Service link 330 may include an NR-Uu interface terminated at satellite 320. In some aspects, satellite 320 may be referred to as a non-terrestrial base station, a regenerative repeater, an onboard processing repeater, etc. In some aspects, satellite 320 may demodulate uplink radio frequency signals and may modulate baseband signals derived from uplink radio signals to produce downlink radio frequency transmissions. Satellite 320 may send downlink radio frequency signals on service link 330. Satellite 320 may provide a cell covering UE 120.

[0056] Example 310 shows a transparent satellite deployment, which may also be referred to as a bent-pipe satellite deployment. In example 310, UE 120 is served by satellite 340 via service link 330. Satellite 340 may be referred to as a transparent satellite, a bent-pipe satellite, a non-terrestrial relay station, etc. Satellite 340 may relay signals received from ground BS 110 via NTN gateway 350. The satellite may repeat the NR-Uu interface via feeder link 360. NTN gateway 350 may communicatively connect satellite 340 and BS 110 using RF link 370. For example, satellite 340 may receive uplink radio frequency transmissions and may send downlink radio frequency transmissions without demodulating the uplink radio frequency transmissions. In some aspects, satellite 340 may convert the uplink radio frequency transmission frequency received on service link 330 to the frequency of the downlink radio frequency transmission on feeder link 360, and may amplify and / or filter the uplink radio frequency transmissions. In some aspects, the UE 120 shown in examples 300 and 310 may be associated with global navigation satellite system (GNSS) capabilities, global positioning system (GPS) capabilities, etc., although not all UEs have such capabilities. Satellites 340 may provide and / or facilitate cells that cover UE 120.

[0057] The service link 330 may include a link between the satellite 340 and the UE 120, and may include one or more of UL or DL. The feeder link 360 may include a link between the satellite 340 and the gateway 350, and may include one or more of an uplink (e.g., from the UE 120 to the gateway 350) or a downlink (e.g., from the gateway 350 to the UE 120).

[0058] 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 much larger than the Doppler effects in terrestrial networks. The Doppler effect on feeder link 360 can be compensated to a certain extent, but may still be associated with a certain amount of uncompensated frequency error. In addition, gateway 350 may be associated with residual frequency error, and / or satellite 320 / 340 may be associated with airborne frequency error. These frequency error sources may cause the received downlink frequency at UE 120 to drift from the target downlink frequency.

[0059] As noted above, Figure 3 is provided as an example. Other examples may differ from those described above. Figure 3 Examples described.

[0060] Figure 44 is a schematic diagram illustrating an example 400 of beam management in an NTN according to the present disclosure. As shown, a satellite 405 can serve a UE 120. The satellite 405 can be, include, be included in, or be similar to Figure 3 Satellite 320, Figure 3 Satellites 340 etc. are shown.

[0061] As shown in reference numeral 410, satellite 405 can use multiple antennas to form multiple beams (shown as "Beam 0", "Beam 1", "...", "Beam 21") that form a beam footprint on the earth. One or more different frequency intervals can be associated with each beam to mitigate interference between beams, thereby facilitating simultaneous transmission and reception capabilities. In some cases, one or more different beams can be associated with a frequency interval. The frequency interval can be or include a BWP. Within each beam, multiple BWPs can be defined to accommodate different UE capabilities, quality of service (QoS) requirements, etc. The orthogonal frequency division multiplexing (OFDM) subcarriers within a BWP are generally orthogonal with respect to each other.

[0062] As satellite 405 moves, the beam footprint moves on the ground. Therefore, as shown in reference numeral 415, different beams can interact with UE 120 as satellite 405 moves. For example, as shown, UE 120 can be located in a footprint associated with a first beam (shown as "Beam 2") at a first moment, and when satellite 405 moves, the UE can be located in a footprint associated with a second beam (shown as "Beam 3") . The movement speed of the satellite may be as high as, for example, 7 km / s or faster. Therefore, UE 120 can switch beams frequently. In order to reduce the Doppler shift generated when satellite 405 moves, satellite 405 can perform frequency precompensation. Frequency precompensation can target the center 420 of the beam footprint.

[0063] In a typical scenario, the network may configure all beams from satellite 405 as cells with an initial BWP pair (uplink and downlink) associated with each beam. Satellite 405 may signal UE 120 which BWP to switch to when the beam footprint moves relative to UE 120. However, terrestrial NR supports up to four configured BWPs for each UE 120. Therefore, the currently supported configurations may not be sufficient to support fast beam switching associated with NTN deployments. As shown in reference numeral 410, when the satellite moves in the direction of arrow 430, the number of BWPs to which UE 120 can switch may be greater than 4 (e.g., 7 in the example shown). Therefore, the connection with satellite 405 may be lost, and / or latency may be introduced if BWP reconfiguration is implemented.

[0064] According to various aspects of the techniques and apparatus described herein, a wireless communication device (which may include a non-terrestrial base station, such as a satellite, a terrestrial base station, etc.) may configure multiple BWPs associated with a beam for a particular UE, and may indicate to the UE the type of handover to which each BWP corresponds. For example, the indication may indicate whether a handover from a first BWP to a second BWP is an intra-beam handover or an inter-beam handover. In this way, various aspects may facilitate efficient BWP handover and robust configuration. Therefore, various aspects may enable more reliable communications with reduced latency and increased throughput.

[0065] As noted above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0066] Figure 5 1 is a schematic diagram illustrating an example 500 associated with BWP switching according to the present disclosure. As shown, a wireless communication device 505 and a UE 120 may communicate with each other. The wireless communication device 505 may include a base station (e.g., Figure 1 Shown and combined Figure 1 BS 110, etc. described herein), non-terrestrial base stations (e.g., Figure 3 Shown and combined Figure 3 Satellite 320 described; Figure 4 Shown and combined Figure 4 Satellite 405, etc. described herein), non-terrestrial relay stations (e.g., Figure 3 Shown and combined Figure 3 Satellite 340 described; Figure 4 Shown and combined Figure 4 Satellite 405 described; etc.) etc.

[0067] As shown by reference numeral 510, the wireless communication device 505 can send a BWP configuration, and the UE 120 can receive the BWP configuration. In some aspects, the BWP configuration can be carried in a radio resource control (RRC) message, a downlink control information (DCI), a medium access control (MAC) control element (MAC-CE), a system information block (SIB), etc. The BWP configuration can indicate one or more BWPs associated with at least one beam. For example, as shown, the BWP configuration can indicate a plurality of BWPs corresponding to the first beam 515 (shown as UL BWP 1, UL BWP 2, DL BWP 1, and DL BWP 2), a plurality of BWPs corresponding to the second beam 520 (shown as UL BWP 3, UL BWP 4, DL BWP 3, and DL BWP 4), etc.

[0068] In some aspects, a BWP in the one or more BWPs may be associated with a beam serving the wireless communication device 505 or a beam of an additional wireless communication device 505. In some aspects, as shown, the BWP configuration may indicate a first initial uplink (UL) BWP (UL BWP 1) associated with the first beam 515, a first initial downlink (DL) BWP (DL BWP 1) associated with the first beam 515, a second initial UL BWP (UL BWP 3) associated with the second beam 520, a second initial DL BWP (DL BWP 3) associated with the second beam 520, and the like.

[0069] In some aspects, the BWP configuration may indicate a first default UL BWP (UL BWP 2) associated with the first beam 515, a first default DL BWP (DL BWP 2) associated with the first beam 515, a second default UL BWP (UL BWP 4) associated with the second beam 520, a second default DL BWP (DL BWP 4) associated with the second beam 520, etc. In some aspects, the BWP configuration may not include a configuration of at least one default BWP associated with at least one beam. In some such cases, the initial BWP of at least one configuration associated with at least one beam may be the at least one default BWP.

[0070] In some aspects, the BWP configuration indicates a maximum number of BWPs. In some aspects, the maximum number of BWPs may be greater than four (e.g., five, six, seven, eight, etc.). In some aspects, the maximum number of BWPs may include a maximum number of intra-beam BWPs, a maximum number of inter-beam BWPs, etc.

[0071] In some aspects, the BWP configuration may indicate an inter-beam BWP switching procedure, as indicated by reference numeral 525. The BWP configuration may indicate a first BWP (e.g., UL BWP 1), an association between the first BWP and the first beam 515, a second BWP (e.g., UL BWP 3), an association between the second BWP (UL BWP 3) and the second beam 520, etc.

[0072] In some aspects, the inter-beam BWP switching process may be configured using RRC messages, SIBs, and the like. In some aspects, the BWP configuration may be carried in an RRC message indicating a second BWP (UL BWP 3) as a target BWP for switching. In some aspects, the second BWP may include an active UL BWP or an active DL BWP. In some aspects, the RRC message may include a setup message (e.g., an RRCSetup message), a reconfiguration message (e.g., an RRCReconfiguration message), and the like.

[0073] As indicated by reference numeral 530, the BWP configuration may indicate an intra-beam BWP switching procedure, a first BWP (UL BWP 1), an association between the first BWP (UL BWP 2) and the first beam 515, a second BWP (UL BWP 2), an association between the second BWP (UL BWP2) and the first beam 515, etc. In some aspects, the intra-beam BWP switching procedure may be configured using an RRC message.

[0074] As indicated by reference numeral 535, the wireless communication device 505 may send, and the UE 120 may receive, an indication of one or more beam parameters associated with at least one beam. In some aspects, the wireless communication device 505 may broadcast the indication. In some aspects, the one or more beam parameters may indicate a Doppler frequency precompensation value associated with the at least one beam, a target location within a beam footprint associated with the at least one beam, a timing adjustment parameter associated with the at least one beam, and the like. In some aspects, the target location may include a center location of the beam footprint. In some aspects, the timing adjustment parameter may include an offset parameter corresponding to a delay component between the wireless communication device 505 and the user equipment 120 within the beam footprint.

[0075] As indicated by reference numeral 540, the UE 120 may send and the wireless communication device 505 may receive an indication of a maximum beam switching time associated with the UE 120 or an indication of an antenna type associated with the UE 120. The maximum beam switching time may indicate a maximum amount of time required for the UE 120 to switch from one beam to another beam. The wireless communication device 505 may determine the beam switching time based at least in part on the maximum beam switching time or the antenna type. In some aspects, the antenna type may include a motor-controlled antenna type, an active electronically scanned array type, etc.

[0076] As indicated by reference numeral 545, the wireless communication device 505 may send and the UE 120 may receive a beam switching time configuration. The beam switching time configuration may indicate a beam switching time associated with the UE 120 switching from a first beam to a second beam as an active beam. In some aspects, the wireless communication device 505 may send and the UE 120 may receive a precompensation switching time configuration. In some aspects, the precompensation switching time configuration may indicate a precompensation switching time associated with the UE 120 switching from a first frequency precompensation to a second frequency precompensation as an active precompensation.

[0077] As indicated by reference numeral 550, the UE 120 may perform a BWP switching procedure to switch from a first BWP to a second BWP as an active BWP based at least in part on the BWP configuration. In some aspects, the BWP switching procedure may include an inter-beam BWP switching procedure, wherein the first BWP and the second BWP are associated with different beams. In some aspects, the BWP switching procedure may include an intra-beam BWP switching procedure, wherein the first BWP and the second BWP are associated with the same beam. In some aspects, the UE 120 may switch from the first BWP as the active BWP to the second BWP as the active BWP within a configured switching time delay, and switch from the serving beam to a target beam associated with the second BWP. In some aspects, the BWP switching may occur within a configured switching time delay based at least in part on the target beam being different from the serving beam.

[0078] As noted above, Figure 5 is provided as an example. Other examples may differ from those described above. Figure 5 Examples described.

[0079] Figure 6 6 is a schematic diagram illustrating an example 600 associated with BWP switching according to the present disclosure. As shown, a wireless communication device 605 and a UE 120 can communicate with each other. The wireless communication device 605 can be or be similar to the Figure 5 Shown and combined Figure 5 A wireless communication device 505 is described.

[0080] As shown in reference numeral 610, the wireless communication device 605 may send and the UE 120 may receive one or more RRC messages including a BWP configuration. The BWP configuration may indicate an intra-beam BWP. In some aspects, the intra-beam BWP may be a BWP associated with a current serving beam (e.g., a beam used to carry an RRC message). As shown in reference numeral 615, the wireless communication device 605 may send and the UE 120 may receive a configuration of an inter-beam BWP. An inter-beam BWP may include a BWP associated with a beam other than a serving beam. In some aspects, the intra-beam BWP and the inter-beam BWP may be indexed separately. An inter-beam BWP may be carried using an RRC message, a SIB, or the like.

[0081] In some aspects, the inter-beam BWP may include an initial BWP associated with other beams, a default BWP associated with other beams, etc. For example, in some aspects, the inter-beam BWP may include an initial BWP for a target beam, and after the UE 120 switches to the initial BWP and the corresponding target beam, the wireless communication device 605 may send an additional BWP configuration indicating an intra-beam BWP associated with the target beam (which will now become the new serving beam).

[0082] As shown by reference numeral 620, the wireless communication device 605 can send and the UE 120 can receive a BWP configuration indicating a target BWP and a BWP type associated with the target BWP. In some aspects, the BWP configuration can be referred to as a BWP switching trigger, a BWP switching message, etc. In some aspects, the BWP configuration shown by reference numeral 620 can be carried in the DCI. In some aspects, the BWP type indicator can be carried in the encoded communication including the DCI. The UE 120 can directly decode the physical downlink control channel (PDCCH) payload containing the encoded communication to extract the BWP type indicator.

[0083] The DCI may include a first set of indices associated with an intra-beam BWP and a second set of indices associated with an inter-beam BWP. In some aspects, the BWP configuration may be carried in the DCI with a BWP identification (ID) field having a maximum number of bits greater than 2. In this manner, the BWP ID field may be able to accommodate more than four configured BWPs to enable greater flexibility in BWP configuration.

[0084] As indicated by reference numeral 625, the UE 120 may determine the BWP type of the target BWP, and as indicated by reference numeral 630, the user equipment 120 may switch to the target BWP. In some examples, the UE 120 may determine the BWP type using a process based at least in part on how the BWP type is indicated using the DCI. In some aspects, the DCI may indicate the BWP type using a BWP type field having at least one bit, and the UE 120 may directly decode the PDCCH payload containing the DCI to extract the at least one bit. For example, the DCI may include DCI format 0_1 ​​or DCI format 1_1, and a bit may be added to indicate the BWP type (e.g., where "0" may indicate an intra-beam BWP and "1" may indicate an inter-beam BWP, or vice versa).

[0085] In some aspects, the DCI may indicate the BWP type using a scrambling sequence applied to the output of a rate matching channel encoder. The first scrambling sequence may indicate the first BWP type, and the second scrambling sequence may indicate the second BWP type. In some aspects, the UE 120 may blindly decode the PDCCH payload containing the DCI using the first scrambling sequence and the second scrambling sequence to determine the BWP type.

[0086] In some aspects, the DCI may use a radio network temporary identifier (RNTI) to indicate the BWP type. In some aspects, a first RNTI of a first subtype may indicate a first BWP type, and a second RNTI of a second subtype may indicate a second BWP type. The RNTI may include a cell RNTI (C-RNTI), a configured scheduling RNTI (CS-RNTI), a modulation and coding scheme cell RNTI (MCS-C-RNTI), etc. For example, in some aspects, C-RNTI subtype 0 may indicate an intra-beam BWP, C-RNTI subtype 1 may indicate an inter-beam BWP, and so on. In some aspects, the UE 120 may use the first RNTI subtype and the second RNTI type to blindly decode the PDCCH payload containing the DCI to determine the BWP type.

[0087] In some aspects, the DCI may use a DMRS sequence to indicate a BWP type. In some aspects, a first DMRS sequence may indicate a first BWP type, and a second DMRS sequence may indicate a second BWP type. The UE 120 may determine the BWP type by examining two DMRS sequences and determining which DMRS sequence results in a correct cyclic redundancy check (CRC). A correct CRC may include a CRC that generates no errors or generates multiple errors that meet a specific error threshold.

[0088] As noted above, Figure 6 is provided as an example. Other examples may differ from those described above. Figure 6 Examples described.

[0089] Figure 7 1 is a schematic diagram illustrating an example 700 associated with BWP switching according to the present disclosure. As shown, a wireless communication device 705 and a UE 120 can communicate with each other. The wireless communication device 705 can be or be similar to the example 700 in FIG. Figure 5 Shown and combined Figure 5 The wireless communication device 505 described in Figure 6 Shown and combined Figure 6 Wireless communication device 605 described; and so on.

[0090] As indicated by reference numeral 710, the wireless communication device 705 may send and the UE 120 may receive an RRC message including a BWP configuration. In some aspects, the BWP configuration may configure a BWP ID field to include a tuple with a unique tuple ID. In some aspects, the tuple ID may indicate a BWP ID and a beam ID. In some aspects, the beam ID may include a cell ID, a synchronization signal block (SSB) index, a dedicated beam ID, etc.

[0091] In some aspects, the beam ID may indicate the target beam. As shown in reference numeral 715, the wireless communication device 705 may send and the UE 120 may receive a DCI indicating a tuple indicating the target BWP and the corresponding target beam. In some aspects, the DCI may include the tuple in the BWP ID field. In some aspects, the number of bits in the BWP ID field may be greater than 2.

[0092] The wireless communication device 705 and / or UE 120 may identify the target beam based at least in part on a determination that the UE 120 is likely to intercept the beam (e.g., interact with the beam, co-locate with the beam, pass through the beam, etc.). In some aspects, the wireless communication device 705 and / or UE 120 may determine that the UE 120 is likely to intercept a particular beam based at least in part on a mobility state of the beam, a mobility state of the UE 120, etc. For example, in some aspects, the wireless communication device 705 may determine that the UE 120 is likely to intercept a particular beam by determining that a probability that the UE 120 and the beam interact within a specified amount of time satisfies a specified probability threshold based on the trajectory, velocity, acceleration, etc. of the beam (and / or the wireless communication device 705 generating the beam).

[0093] As indicated by reference numeral 720, UE 120 may determine a target BWP and a target beam. UE 120 may determine the target BWP and the target beam based at least in part on the tuple ID. As indicated by reference numeral 725, UE 120 may perform a BWP switching procedure based at least in part on the target BWP and the target beam. In some aspects, UE 120 may reset a default BWP associated with UE 120 to a default BWP associated with a target beam associated with a second BWP.

[0094] As noted above, Figure 7 is provided as an example. Other examples may differ from those described above. Figure 7 Examples described.

[0095] Figure 88 is a schematic diagram illustrating an example 800 associated with BWP switching according to the present disclosure. As shown, a wireless communication device 805 and a UE 120 can communicate with each other. The wireless communication device 805 can be or be similar to the Figure 5 Shown and combined Figure 5 The wireless communication device 505 described in Figure 6 Shown and combined Figure 6 The wireless communication device 605 described in Figure 7 Shown and combined Figure 7 Wireless communication device 705 described; and so on.

[0096] As indicated by reference numeral 810, the wireless communication device 805 may send and the UE 120 may receive the intra-beam BWP PID. As indicated by reference numeral 815, the wireless communication device 805 may send and the UE 120 may receive the inter-beam BWP ID. In some examples, the intra-beam BWP ID and the inter-beam BWP PID may be signaled separately in a manner that reduces signaling overhead. For example, in some aspects, the intra-beam BWP ID may be carried in the DCI and the inter-beam BWP ID may be carried in the MAC-CE. In some aspects, the intra-beam BWP ID may be carried in the DCI and the inter-beam BWP ID may be carried in the RRC message. In some aspects, the intra-beam BWP ID may be carried in the MAC-CE or RRC message and the inter-beam BWP ID may be carried in the DCI.

[0097] In some aspects, the inter-beam BWP ID may be carried in a dedicated DCI format. In some aspects, the dedicated DCI format may include a set of resource elements indicating the inter-beam BWP ID, the wireless communication device ID, the beam ID, etc. In some aspects, the inter-beam BWP ID may indicate an initial UL BWP, an initial DL BWP, a default UL BWP, a default DL BWP, etc. In some aspects, the beam ID may include a cell ID, an SSB index, a dedicated beam ID, etc.

[0098] In some aspects, the wireless communication device 805 can indicate a dedicated DCI format to the UE 120. In some aspects, the indication can include an RRC configured search space, a C-RNTI used to address the UE 120 and a format ID field in the DCI, an inter-beam BWP switching RNTI used to address the UE 120, a specified scrambling sequence applied to the rate matching channel encoder output, a specified DMRS sequence, a dedicated DCI format ID encoded into an encoded message including the DCI, and the like.

[0099] As shown in reference numeral 820, the UE 120 may send a feedback message, and the wireless communication device 805 may receive the feedback message. In some aspects, the feedback message may confirm the receipt of the DCI. As shown in reference numeral 825, the UE 120 may perform a BWP switching process to switch to the indicated target BWP. As shown in reference numeral 830, the wireless communication device 805 may send a resource allocation, and the UE 120 may receive the resource allocation. In some aspects, the wireless communication device 805 may send the resource allocation based at least in part on receiving the feedback message. In some aspects, the resource allocation may include uplink resources, and the UE 120 may use the uplink resources and the target BWP to send a scheduling request.

[0100] As noted above, Figure 8 is provided as an example. Other examples may differ from those described above. Figure 8 Examples described.

[0101] Fig. 9 9 is a diagram illustrating an example process 900 performed, for example, by a UE according to the present disclosure. Example process 900 is an example in which a UE (eg, UE 120, etc.) performs operations associated with a BWP switch.

[0102] like Fig. 9 As shown, in some aspects, process 900 may include receiving a BWP configuration indicating one or more BWPs associated with at least one beam (block 910). For example, the UE (e.g., using receive processor 258, controller / processor 280, memory 282, etc.) may receive a BWP configuration indicating one or more BWPs associated with at least one beam, as described above.

[0103] like Fig. 9 As further shown, in some aspects, process 900 may include: switching from a first BWP in one or more BWPs as an active BWP to a second BWP in one or more BWPs as an active BWP based at least in part on the BWP configuration (block 920). For example, the UE (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, etc.) may switch from a first BWP in one or more BWPs as an active BWP based at least in part on the BWP configuration, as described above.

[0104] Process 900 may include additional aspects, such as any single aspect or any combination of the aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0105]

[0096] With respect to process 900, in some aspects, the BWP configuration is carried in at least one of an RRC message, a DCI, a MAC-CE, a SIB, or a combination thereof.

[0106]

[0097] With respect to process 900, in some aspects at least one beam is associated with a non-terrestrial wireless communication device.
