[0003] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may use technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication for multiple communication devices (which may be further referred to as user equipment (UE)).

[0153] In some wireless communication environments, such as in non-terrestrial networks (e.g., satellite-supported networks), beam switching may occur frequently relative to other environments (e.g., terrestrial networks). This may be due to the relatively small beam coverage when the satellite may be moving at a relatively high rate. The network may configure the user equipment (UE) with each beam supported by the satellite and the initial resources (e.g., bandwidth portions) for each beam. When the beam coverage area moves (or when the UE moves), the network may signal the UE about which bandwidth portion to utilize. In some cases, the wireless communication system may limit the number of bandwidth portions configured at the UE. This may be due to the size of the field used to signal the bandwidth portion. Since the UE and the network may be mobile, the limitation of the bandwidth portion may affect the ability of the UE to efficiently switch between beams.

[0154] The technology described herein provides efficient signaling of bandwidth parts and beams by network entities (such as satellites). It should be understood that the described implementations can be applicable to non-terrestrial as well as terrestrial networks. Therefore, the network entity can be an example of a satellite, such as a low earth orbit (LEO) satellite, a base station, etc. According to one implementation, the network entity can use MAC-CE (MAC-CE) messaging to signal the mapping between the index value set and the bandwidth part identifier and the corresponding beam identifier. In some cases, the beam identifier corresponds to a beam supported by a satellite or other type of network entity (such as a base station). The index value set signaled via MAC-CE can be a possible index value, one of which can be indicated by a specific field in a control message (such as a DCI (DCI) message). For example, a DCI message may include a field indicating a bandwidth part (e.g., bwp-id). The field can be limited to a specific number of bits, such as two bits. In such a case, the field may be able to indicate 4 different index values. Therefore, MAC-CE messaging can map each of the four index values ​​to a bandwidth part identifier and a beam identifier. Thereafter, DCI messaging may be used to signal one of the indexes, enabling the UE to switch to a bandwidth part and / or beam based on the DCI indication. Thus, as the UE moves between coverage areas of network entities (or as a network entity such as a satellite moves relative to the UE), MAC-CE messaging may update the mapping and the DCI may indicate the bandwidth part and beam to be used by the UE. This process may support efficient bandwidth part and beam switching in a mobile environment.

[0155] According to other examples, the network entity may use MAC-CE messaging to indicate a mapping of a transmission configuration indicator (TCI) state to a set of TCI code points. These TCI states may be examples of TCI states including indications of beams such as satellite beams. DCI messaging may include an indication of TCI code points. Therefore, based on DCI messaging, the UE may identify the TCI state and the corresponding beam to be used for communication with the network entity. The DCI messaging may also include an indication of a bandwidth part (e.g., a bwp-id field). Therefore, using MAC-CE messaging to map TCI code points to TCI states with beam identifiers, and using DCI messaging to signal TCI code points and bandwidth part identifiers, the UE can efficiently switch between bandwidth parts and beams. In some examples, a TCI state including a beam identifier (e.g., a satellite beam identifier) ​​may be preconfigured at the UE via RRC (RRC) signaling (e.g., a radio resource control message). The TCI state may include parameters for configuring a quasi co-location (QCL) relationship between one or two downlink reference signals and a downlink shared channel, a demodulation reference signal (DMRS) port of a downlink control channel, or a CSI-RS port of a channel state information reference signal (CSI-RS) resource. The TCI state may signal to the UE which beam(s) are to be used for communication with a network entity. The TCI code point may be an example of a table having a finite size.

[0156] According to other examples, the network entity may use RRC signaling to configure the TCI state with a beam identifier (e.g., a satellite beam identifier). MAC-CE messaging may be used to signal the TCI state via a TCI state identifier. In some cases, the TCI state signaled via MAC-CE includes an indication of a set of sub-TCI states. Thus, MAC-CE signaling may indicate a TCI state and a sub-TCI state. This technique may avoid utilizing a set of TCI state identifiers that may be used for other types of TCI states.

[0157] Certain aspects of the subject matter described herein may be implemented to support a bandwidth fraction and beam signaling framework. For example, the various TCI state, bandwidth fraction, and beam identifier signaling techniques described herein may support bandwidth fraction and beam switching in scenarios where the number of bandwidth fractions or beams that may be configured at a device such as a UE may be limited. Additionally, these techniques may support efficient bandwidth fraction and beam switching in environments where bandwidth fraction and beam switching is frequent. Thus, the supported techniques may include improved network operation and, in some examples, may improve network efficiency.

[0158] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are further described with reference to wireless communication systems and process flow diagrams. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams involving bandwidth portion switching through activation and signaling.

[0159] Figure 1 An example of a wireless communication system 100 that supports bandwidth fraction switching by activation and signaling according to one or more aspects of the present disclosure is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE network, an improved LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, or communications with low-cost and low-complexity devices, or any combination thereof.

[0160] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100, and may be devices of different forms or with different capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which UEs 115 and base stations 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support transmission of signals according to one or more radio access technologies.

[0161] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. UEs 115 may be devices of different forms or with different capabilities. Figure 1 Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 as shown in .

[0162] The base stations 105 may communicate with the core network 130, or communicate with each other, or perform both of the above operations. For example, the base station 105 may be connected to the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3 or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105) on the backhaul link 120 (e.g., via X2, Xn or another interface), or communicate with each other indirectly (e.g., via the core network 130), or perform both of the above operations. In some examples, the backhaul link 120 may be or include one or more wireless links. The UE 115 may communicate with the core network 130 via a communication link 155.

[0163] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home Evolved Node B, or other appropriate terminology.

[0164] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other appropriate terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various items such as appliances, or vehicles, meters, and among other examples.

[0165] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, such as Figure 1 as shown in .

[0166] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating operations for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0167] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate operations for other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be placed according to a channel grid to be discovered by a UE 115. A carrier may operate in a standalone mode, where a UE 115 may perform initial acquisition and connection via a carrier, or a carrier may operate in a non-standalone mode, where a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0168] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0169] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, a carrier bandwidth may be referred to as a "system bandwidth" of a carrier or wireless communication system 100. For example, a carrier bandwidth may be one of a number of determined bandwidths for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). A device of the wireless communication system 100 (e.g., a base station 105, a UE 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0170] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, wherein the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate for the UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communication with the UE 115.

[0171] One or more numerologies for a carrier may be supported, where the numerologies may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs.

[0172] The basic time unit (which may be referred to as T s =1 / (Δf max ·N f ) seconds sampling period, where Δf maxIt can represent the maximum supported subcarrier spacing, and N f The time intervals for the base station 105 or the UE 115 may be expressed as multiples of a maximum supported discrete Fourier transform (DFT) size). The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0173] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of a cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0174] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in the form of bursts of shortened TTIs (sTTIs)).

[0175] Physical channels may be multiplexed on a carrier according to various techniques. For example, one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique may be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by the number of symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0176] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots or other types of cells, or any combination thereof). The term "cell" can refer to a logical communication entity used to communicate with the base station 105 (e.g., on a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID) or other identifier) ​​for distinguishing adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of the base station 105), the range of such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping geographic coverage areas 110, as well as other examples.

[0177] A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 115 with a service subscription to a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 than a macro cell, and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to a UE 115 with a service subscription to a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user in a residence or office). A base station 105 may support one or more cells, and may also support the use of one or more component carriers to communicate on one or more cells.

[0178] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0179] In some examples, base stations 105 may be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for respective geographic coverage areas 110 using the same or different radio access technologies.

[0180] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operation.

[0181] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a human interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service billing.

[0182] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0183] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication, and can be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably in this article.

[0184] In some examples, UE 115 may also be able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0185] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicle can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicle can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, the vehicle in the V2X system can communicate with roadside infrastructure (such as a roadside unit), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or communicate with both.

[0186] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connection, and other access, routing or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets to an external network or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the core network 130. User IP packets may be transmitted through a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0187] Some of the network devices, such as the base station 105, may include subcomponents such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).

[0188] The wireless communication system 100 may operate using one or more frequency bands in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The region from 300 MHz to 3 GHz may be referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be sufficient to penetrate structures for macro cells to provide services to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmission using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0189] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as a centimeter band) or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antennas of the corresponding devices may be smaller and more closely spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer from even greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The technology disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may differ according to countries or regulatory agencies.

[0190] The electromagnetic spectrum is often subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified with the frequency range names 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 often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. Similar naming issues sometimes arise with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz), and the EHF band is identified as a "millimeter wave" band by the International Telecommunication Union (ITU).

[0191] Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as the frequency range name FR3 (7.125GHz–24.25GHz). The frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the characteristics of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations above 52.6GHz. For example, three higher operating bands have been identified as the frequency range names FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0192] In view of the above, unless otherwise specifically stated, it should be understood that the term "sub-6 GHz" and the like, if used herein, can broadly refer to frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like, if used herein, can broadly refer to frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band.

[0193] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) can employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band can be based on a carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating in a licensed band. Operations in an unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, as well as other examples.

[0194] The base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operations or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having antenna ports of a number of rows and columns that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.

[0195] The base station 105 or UE 115 can use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technology may be referred to as spatial multiplexing. For example, a transmitting device may send multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

[0196] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to form or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating at a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0197] As part of the beamforming operation, the base station 105 or the UE 115 may use beam scanning techniques. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communications with the UE 115. The base station 105 may send some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 may send signals based on different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or by a receiving device (such as the UE 115)) to identify a beam direction for subsequent transmission or reception by the base station 105.

[0198] Base station 105 may transmit some signals (such as data signals associated with a particular receiving device, such as UE 115) in a single beam direction (e.g., a direction associated with the receiving device). In some examples, the beam direction associated with transmission along the single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 having the highest signal quality or otherwise acceptable signal quality.

[0199] In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may generate a combined beam for transmission (e.g., from the base station 105 to the UE 115) using a combination of digital precoding or radio frequency beamforming. The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may send reference signals (e.g., cell-specific reference signals (CRS), CSI-RS) that may or may not be precoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type of codebook, a linear combination type of codebook, a port selection type of codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques to send signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to send signals in a single direction (e.g., to send data to a receiving device).

[0200] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, the receiving device (e.g., UE 115) can try multiple reception configurations (e.g., directional listening). For example, the receiving device can try multiple reception directions by receiving via different antenna subarrays, by processing signals received according to different antenna subarrays, by receiving according to different reception beamforming weight sets applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets), or by processing received signals according to different reception beamforming weight sets applied to signals received at multiple antenna elements of the antenna array (any of the above operations may be referred to as "listening" according to different reception configurations or reception directions). In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0201] The wireless communication system 100 can be a packet-based network operated according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer can be based on IP. The radio link control (RLC) layer can perform packet segmentation and reorganization to transmit on a logical channel. The medium access control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the RRC RRC protocol layer can provide the establishment, configuration and maintenance of the RRC connection (which supports radio bearers for user plane data) between the UE115 and the base station 105 or the core network 130. At the physical layer, the transport channel can be mapped to the physical channel.

[0202] UE 115 and base station 105 can support retransmission of data to increase the possibility that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technology for increasing the possibility that data is correctly received on communication link 125. HARQ can include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC) and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support the same time slot HARQ feedback, wherein the device can provide HARQ feedback for data received in the previous symbol in the time slot in a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0203] The wireless communication system 100 may also include one or more satellites 160. The satellite 160 may communicate with the base station 105 (also referred to as a gateway in the NTN) and the UE 115 (or other high altitude or ground communication equipment). The satellite 160 may be any suitable type of communication satellite configured to relay communications between different end nodes in the wireless communication system. The satellite 160 may be an example of a space satellite, a balloon, a spacecraft, an airplane, a drone, an unmanned aerial vehicle, etc. In some examples, the satellite 160 may be in a geosynchronous or geostationary orbit, a LEO or a medium earth orbit (MEO), and may support a global navigation satellite system (GNSS). The satellite 160 may be a multi-beam satellite configured to provide services for multiple service beam coverage areas in a predefined geographic service area. The satellite 160 may be at any distance from the surface of the earth.

[0204] In some cases, the cell can be provided or established by satellite 160 as part of a non-terrestrial network. In some cases, satellite 160 can perform the functions of base station 105, act as a bent pipe satellite, or can act as a regenerative satellite, or a combination thereof. In other cases, satellite 160 can be an example of an intelligent satellite or a satellite with intelligence. For example, an intelligent satellite can be configured to perform more functions than a regenerative satellite (e.g., can be configured to perform a specific algorithm outside the algorithm used in the regenerative satellite, be reprogrammed, etc.). A bent pipe transponder or satellite can be configured to receive signals from a ground station and send these signals to different ground stations. In some cases, a bent pipe transponder or satellite can amplify a signal or move from an uplink frequency to a downlink frequency. A regenerative transponder or satellite can be configured to relay signals like a bent pipe transponder or satellite, but other functions can also be performed using onboard processing. Examples of these other functions can include: demodulating a received signal, decoding a received signal, recoding a signal to be sent, or modulating a signal to be sent, or a combination thereof. For example, a bent-pipe satellite (e.g., satellite 160) can receive a signal from a base station 105 and can relay the signal to a UE 115 or base station 105, or vice versa. A UE 115 can communicate with a cell provided or established by a satellite 160 (e.g., via a base station 105 or a satellite 160 performing the functions of a base station 105).

[0205] In some environments, UE 115 may perform multiple beam switching in a short period of time, and each beam may be associated with one or more resources (such as bandwidth parts). UE 115 may also be limited in the number of bandwidth parts that it can use at a specific time. This number limitation may inhibit the ability of UE 115 to switch efficiently between beams. For example, in a LEO system, satellite 160 may support a beam coverage area that is smaller than the orbital velocity of satellite 160. Therefore, UE 115 may frequently switch between beams supported by different satellites 160. The limitation of the number of bandwidth parts may limit the ability of UE 115 to communicate efficiently in such environments. This frequent beam switching may occur in other systems different from LEO systems, such as MEO systems, GNSS and other non-ground and ground systems. Therefore, the solution described herein may be applicable to various different systems.

[0206] Various aspects of the present disclosure described herein provide various signaling techniques that can be used to signal bandwidth parts and beams. In one example, MAC-CE signaling (e.g., via a communication manager 101 of a network entity such as a base station 105 or a satellite 160) can be used to indicate a mapping between a set of indices and beam identifiers and bandwidth part identifiers. The beam identifier and bandwidth part identifier can be examples of tuples that are mapped to specific indexes via a MAC-CE message. A DCI message (e.g., a downlink control information message) from the communication manager 101 can include an indication of one of the indexes. Thus, when the DCI is sent to the UE 115, the communication manager 102 of the UE 115 can identify the bandwidth part and beam used to communicate with the network entity (such as a base station 105 or a satellite). When the UE 115 moves (or the satellite moves), MAC-CE messaging can be used to update the mapping. Thus, using a combination of MAC-CE messaging and DCI messaging, the network can signal the UE 115 about which beams and bandwidth parts to use for communication.

[0207] Another example described herein utilizes MAC-CE messaging to map TCI states to TCI code points that can be signaled via DCI. These TCI states may include an indication of a beam identifier (such as a satellite beam identifier). Thus, the DCI message may indicate the bandwidth portion (e.g., bwp-id field) and the TCI code point to the UE 115. Based on these DCI indications, the UE 115 may identify the beam and bandwidth portion to be used for network communications. In some cases, the TCI states may be configured via RRC signaling. Another example uses these TCI states, but the MAC-CE messaging may include an indication of the TCI state that the UE 115 will use for network communications. These and other implementations will be further described with reference to the following figures.

[0208] Figure 2 An example of a wireless network 200 that supports bandwidth portion switching through activation and signaling according to one or more aspects of the present disclosure is shown. In some examples, the wireless network 200 can implement aspects of the wireless communication system 100. The wireless network 200 includes a network entity 205 and a UE 115-a, which can be as described with respect to Figure 1 An example of a UE 115 is described. The network entity 205 is shown as a satellite (e.g., Figure 1 Satellite 160), but the network entity can be as Figure 1 1. The depicted example is an example of a base station 105. The network entity may also be an example of a satellite 160 (eg, a LEO satellite). Thus, wireless network 200 may be an example of a non-terrestrial network, a terrestrial network, or a combination of non-terrestrial and terrestrial networks.

[0209] In some wireless communication environments, beam switching may be frequent compared to other environments. Figure 2 As shown in , beam coverage area 220 (e.g., the coverage area of ​​a beam) may be small relative to the speed of network entity 205. In other examples, the frequency of beam switching may depend on the mobility of UE 115, and / or the mobility of UE 115 combined with the movement of base station 105. The network may configure each beam from a satellite as a cell with an initial bandwidth portion of each beam. Figure 2 Each pattern of beam coverage areas 220 in the figure may represent a different bandwidth portion, and each beam coverage area 220 may correspond to a specific beam identified within the coverage area and transmitted by a network entity. For illustrative purposes, the beam coverage area 220 is indicated as a hexagon, but the coverage area may be associated with a variety of shapes, such as a circle, an ellipse, a hexagon, etc. The shape and size of the beam coverage area 220 may depend on the distance of the transmitting device (e.g., the network entity 205) from the earth's surface, the transmission angle, the power level associated with the beam, the shape and structure of the antenna, etc. In addition, adjacent beam coverage areas 220 may have different shapes and sizes, depending on the transmission angle and distance of the transmitting device, the structure of the antenna, etc. In some cases, the beam coverage areas 220 may overlap. The network (e.g., the network entity 205) may signal to the UE 115-a which bandwidth portion to utilize when the beam coverage area 220 moves or the UE 115-a moves. In some cases, the network may support a limited number of bandwidth portions that each UE 115 may configure. For example, UE 115-a may be configured with four bandwidth parts at a particular instance in time. This bandwidth part restriction may not be sufficient because in some environments, such as non-terrestrial networks, the number of bandwidth parts that UE 115 may switch to may be greater than four in a short period of time. Figure 2 As shown in , UE 115 - a can switch between seven bandwidth portions along path 225 , as shown by the various patterns of beam coverage areas 220 .

[0210] Each beam may be associated with a specific bandwidth portion. For example, one or more bandwidth portions may be configured for a beam (e.g., a satellite beam) of each UE 115. Each satellite beam may be configured with an initial uplink bandwidth portion and an initial downlink bandwidth portion. Each satellite beam may also be configured with a default uplink bandwidth portion and a default downlink bandwidth portion for the UE 115. If the default uplink / downlink bandwidth portion is not configured, the default uplink bandwidth portion may be configured as the initial uplink bandwidth portion, and the default downlink portion may be configured as the initial downlink bandwidth portion. Each satellite beam may be configured with an additional bandwidth portion. As described herein, the network may configure the bandwidth portion in the satellite beam for the UE 115, and the configuration may be transmitted to the UE 115 via a system information block (SIB) message or an RRC message. For example, if the bandwidth portion is an initial bandwidth portion, the SIB may be used. Otherwise, the RRC message may be used for transmission. There may be two types of bandwidth portion switching. In inter-beam switching, the UE 115 switches from a bandwidth portion in one satellite beam to a bandwidth portion in a second satellite beam. In intra-beam bandwidth part switching, UE 115 switches from a first bandwidth part to a second bandwidth part in the same satellite beam.

[0211] The parameter switchTime may indicate the time required for the UE 115 to adjust the antenna pointing direction to change from one network entity 205 to another network entity 205 (e.g., from satellite to satellite), and may take into account the time required for the UE 115 to change frequency precompensation. The switchTime parameter may include a value that depends on the antenna type (e.g., a very small aperture terminal (VSAT) antenna or an active electronically scanned array (AESA) antenna). T1 may be indicated for a motor-steered antenna, and T2 may be indicated for an AESA antenna, where T1 is greater than or equal to T2.

[0212] To support efficient beam and bandwidth portion exchange, various signaling techniques may be used as described herein. In one implementation, a first control message 210 (which may be an example of a MAC-CE message) may indicate a mapping of a bandwidth portion identifier and a beam identifier (e.g., a satellite beam identifier) ​​to an index. That is, the network may jointly encode the bandwidth portion identifier and the beam identifier. For example, a tuple (bandwidth portion identifier, beam identifier) ​​may be assigned or mapped to a unique identifier, such as an index value. The satellite beam identifier may be an example of a cell identifier (e.g., each satellite beam is configured as a separate cell), a synchronization signal block (SSB) index, or a general satellite beam identifier. The satellite beam identifier may indicate a satellite beam that the UE 115 may enter within a specific time interval due to mobility such as satellite mobility. In some cases, the encoding may be signaled by the SIB or RRC.

[0213] According to the technique, the network may select n tuples or associations of bandwidth part identifiers and satellite beam identifiers and map these associations to unique indices of ceil(log2n) bits and thus activate these associations. These indices may be signaled to UE 115-a via MAC-CE. The mapping may follow rules agreed upon between the network and UE 115-a. For example, where the indexes may be signaled via two bits (e.g., using the bwp-id field of the DCI), the ordering of the bandwidth part identifiers and satellite beam identifier associations as signals may inform the index mapping. That is, the first association may be mapped to 00, the second association may be mapped to 01, the third association may be mapped to 10, and the fourth association may be mapped to 11. In some cases, the bandwidth parts in the association may be all uplink bandwidth parts or all downlink bandwidth parts.

[0214] Thus, the bwp-id field (or a different field) in the DCI may be used to indicate an association between a bandwidth part identifier and a beam identifier. When the UE 115-a receives the second control message 215 (e.g., DCI), the UE 115-a may demap the bwp-id field to a bandwidth part identifier and a satellite beam identifier, and switch to the associated bandwidth part and beam (if the beam is different from the current beam). In addition, if the indicated beam is different from the current serving beam, the UE 115-a may reset the default bandwidth part to the bandwidth part associated with the indicated satellite beam. Switching to a new beam may also include adjusting beam-specific frequency compensation, timing parameters, and the like. In some cases, the association between a bandwidth part identifier and a beam is indicated via a specific bandwidth part. For example, a bandwidth part may include multiple parameters, and the parameters may indicate a beam associated with the bandwidth part. Thus, the bwp-id field of the DCI may indicate a bandwidth part including an indication of the beam that the UE 115-a will use for communication.

[0215] As discussed, the first control message 210 can be an example of a MAC-CE message, and the second control message 215 can be an example of a DCI message. Thus, the first control message 210 can be an example of a MAC layer message, and the second message can be an example of a physical layer message. Since MAC layer messaging can be a slower or less efficient form of messaging than physical layer messaging, in some examples, MAC layer messaging can be used less frequently than physical layer messaging. Thus, using the techniques described herein, MAC layer messaging can be used to provide mappings (e.g., bandwidth portion identifiers and beam identifiers to index mappings or TCI states to index mappings), and physical layer messaging can be used to switch between beams and / or bandwidth portions more frequently based on the mappings. Other messaging layers are contemplated within the scope of the present disclosure.

[0216] According to another technique, the network may use a TCI state to indicate a beam, such as a satellite beam. For example, a new TCI state type may be used to indicate a satellite beam identifier, which may be an example of a cell identifier, an SSB index, or a more general satellite beam identifier. According to this technique, RRC signaling may configure a set of TCI states, where each of these states includes a TCI state identifier (e.g., a transmission configuration indicator state identifier), a TCI type (e.g., a "satellite beam index type"), and a beam identifier (e.g., a satellite beam identifier). That is, RRC signaling may configure the UE with a set of transmission configuration indicator states, each TCI state including a corresponding transmission configuration indicator state identifier, a corresponding satellite beam identifier, and a transmission configuration indicator state type (e.g., a transmission configuration indicator state type of a satellite beam index type). MAC-CE messaging (e.g., a first control message 210) may be used to map a subset of these configured TCI states to an index, as described with respect to the first technique. In some examples, the MAC-CE message may include a bitmap, where each value activates / deactivates a corresponding TCI state (e.g., a corresponding transmission configuration indicator state). The bitmap may be used to map active TCI states to TCI code points. The first activated TCI state is mapped to a code point with a value of 0, the second activated TCI state is mapped to a code point with a value of 1, and so on. The TCI state subset may include an indication of a beam identifier corresponding to a beam that the UE 115-a may enter in a time interval. Thus, the subset may be updated over time via MAC-CE messaging. To signal the UE 115-a to switch to downlink bandwidth portion w and satellite beam b, the network may send a DCI message (e.g., a second control message 215) with the bwp-id field set to w and the TCI field set to a TCI code point of a TCI state having a "satellite beam index type" and indicating a satellite beam identifier b.

[0217] UE 115-a may behave based on whether the DCI (e.g., second control message 215) indicates a different beam than the current beam, a different bandwidth portion, or both. For example, if the TCI state indicated by the TCI field has a "satellite beam index type" and the satellite beam identifier is equal to b and b is different from the identifier of the current serving satellite beam, then UE 115-a may switch satellite beam b in switchTime. The bwp-id field of the DCI may indicate a downlink bandwidth portion in a new satellite beam for UE 115-a to utilize. UE 115-a may reset a default downlink bandwidth portion configured for the UE in the satellite beam indicated in the TCI state. Switching to a new satellite beam may include adjusting beam-specific frequency compensation, timing parameters, etc. In some cases, if a downlink bandwidth portion switch occurs, the network may configure (e.g., via RRC) whether the corresponding uplink bandwidth portion is to be switched. That is, if the DCI indicates a new downlink bandwidth portion, the network entity 205 may signal, via RRC, that the UE 115-a will switch uplink bandwidth portions.

[0218] If b is the same as the identifier of the currently serving satellite beam, the UE 115-a may not switch satellite beams. If the bandwidth part identifier is different from the identifier of the active bandwidth part, the UE may switch to the indicated bandwidth part to communicate with the network entity 205. Otherwise (e.g., the bandwidth part identifier is the same as the active bandwidth part), the UE 115-a may not switch to another bandwidth part.

[0219] According to another technique, a TCI state configuration as described above may be used in conjunction with MAC-CE signaling. That is, new TCI states with a beam identifier (e.g., a satellite beam identifier), a “satellite beam index type,” and the like may be used. In addition, these TCI states may be configured using RRC. In order for the UE to switch to satellite beam b, the network (e.g., the network entity 205) may send a MAC-CE message indicating a TCI state identifier with the type “satellite beam index type” and the satellite beam identifier b. In some cases, the TCI state may indicate a serving cell identifier and a control resource set (CORESET) identifier. The behavior of the UE 115-a may depend on whether the beam and / or bandwidth portion is switched by a MAC-CE (e.g., a first control message 210) and a DCI message (e.g., a second control message 215).

[0220] Upon receiving the MAC-CE, the UE 115-a may identify the TCI state indicated by the TCI state identifier field of the MAC-CE. If the TCI state has the type "satellite beam index type", the UE 115-a may switch to satellite beam b (indicated by the TCI state) and the corresponding default downlink bandwidth portion or initial downlink bandwidth portion for the duration switchTime. In addition, the UE 115-a may switch to the default uplink bandwidth portion or initial uplink bandwidth portion in satellite beam b (e.g., based on RRC configuration, as described herein). If the indicated TCI state has other types (e.g., QCL type A), the UE 115-a may interpret the MAC-CE as applying the TCI state to the CORESET identified by the CORESET ID and may take action accordingly. If the DCI indicates that the UE 115-a will switch downlink bandwidth portions, the CORESET may change. For each CORESET, the associated TCI states including the activated TCI state may also change. Thus, if the active state has the type "satellite beam index type" as described herein, UE 115-b can perform beam switching based on the beam identified in the TCI state. Thus, UE 115-a can also switch to the default uplink bandwidth portion or the initial uplink bandwidth portion in the satellite beam indicated by the TCI state. Figure 3A An example of a configuration 300-a of a new TCI state according to one or more aspects of the present disclosure is shown, which can be used in the example implementation or implementation using TCI states and DCI signaling. Configuration 300-a includes a TCI state 305, which includes fields for a serving cell identifier, a CORESET identifier, and a TCI state identifier. The TCI state identifier can correspond to a TCI state type of a satellite beam index type. In addition, the serving cell identifier can correspond to a satellite beam identifier.

[0221] In some cases, an additional new TCI status type of "Satellite Beam Index Type" may be defined. This TCI type may include a TCI status identifier and up to 2 n The sub-TCI state type may include an n-bit sub-TCI state identifier, a satellite beam identifier, and a satellite identifier. The network entity 205 may configure (e.g., using RRC signaling) a TCI state of type “satellite beam index type” and configure up to 2 nThe network may also configure other types of TCI states. In order to signal UE 115-b to switch to satellite beam b, the network may configure and signal a MAC-CE that carries a TCI state identifier of a TCI state of type “satellite beam index type” and a sub-TCI state ID of a sub-TCI state with satellite beam identifier b.

[0222] In such a case, UE 115-a may act based on signaling. Upon receiving the MAC-CE, UE 115-a may identify the TCI state indicated by the TCI state identifier of the MAC-CE. If the TCI state has the type "satellite beam index type", the n-bit field indicates the sub-TCI state ID. Based on the n-bit field, UE 115-a may identify the sub-TCI state and obtain the satellite beam identifier from the sub-TCI state. UE 115-a may switch to the default downlink bandwidth portion or initial downlink bandwidth in the satellite beam indicated in the sub-TCI state. UE 115-a may also switch to the downlink bandwidth portion or initial uplink bandwidth in satellite beam b. If the TCI state has other types (e.g., QCL type A), UE 115-a may interpret the MAC-CE as applying the TCI state to the CORESET identified by the CORESET identifier and take action accordingly. Figure 3B An example of a configuration 300-b (e.g., a TCI state configuration) using TCI states and sub-TCI states according to one or more aspects of the present disclosure is shown. Configuration 300-b includes TCI state 310 and TCI state 315. TCI state 310 (e.g., a transmission configuration indicator state) includes a serving cell identifier, a sub-TCI state identifier, and a TCI state identifier. The TCI state identifier may correspond to a TCI state type of a satellite beam index type (e.g., a transmission configuration indicator state type), and the sub-TCI state identifier may indicate an identifier of the TCI state 315, etc. The TCI state 315 includes a serving cell identifier, a CORESET identifier, and a TCI state identifier. The serving cell identifier of the TCI state 315 may include an indication of a beam (e.g., a satellite beam identifier).

[0223] Figure 4 An example of a mapping configuration 400 that supports bandwidth portion switching through activation and signaling according to one or more aspects of the present disclosure is shown. In some examples, the mapping configuration 400 can implement aspects of the wireless communication system 100. The mapping configuration can be configured as described in relation to Figure 2 The network entity 205 and UE 115-b described above are implemented, and UE 115-b can be as described in Figure 1 and2 An example of UE 115 is described.

[0224] The mapping configuration may be signaled to the UE via MAC-CE messaging (e.g., a first control message), and the bandwidth part and satellite beam identifier may be signaled to the UE 115-b using a DCI message (e.g., a second control message). The network entity may select a subset of the set of associations between bandwidth part identifiers and beam identifiers 405 and map these associations to a set of indices that may be signaled via DCI messaging. Figure 4 As shown in , association (0,3) is mapped to index 00, association (1,3) is mapped to 01, association (0,4) is mapped to 10, and association (0,0) is mapped to 11. The mapping may be indicated based on the order in the MAC-CE message transmission. That is, the MAC-CE message transmission may indicate (0,3), (1,3), (0,4), and then (0,0), which may imply an ordered mapping to 00, 01, 10, 11, and the UE-specific bandwidth portion 410. It should be understood that other types of mapping rules may be used.

[0225] Based on the mapping, the bwp-id field of the DCI (or another field of the DCI) may signal one of the indices. For example, the DCI may indicate 00, which indicates that the UE 115-b is to communicate with the network entity using a UE-specific bandwidth portion corresponding to bandwidth portion identifier 0 and a satellite beam corresponding to satellite beam identifier 3. It should be appreciated that these mappings may be used with other network entities, such as a base station 105 in a terrestrial network.

[0226] Figure 5 An example of a process flow diagram 500 for supporting bandwidth portion switching through activation and signaling according to one or more aspects of the present disclosure is shown. In some examples, the process flow diagram 500 can implement aspects of the wireless communication system 100. The process flow diagram 500 includes a UE 115-c and a network entity 505, which can be as described with respect to Figure 1 Examples of corresponding devices described in 3.

[0227] According to one implementation, at 510, the UE 115-c may receive a first control message from the network entity 505 indicating a mapping of each index in the set of indexes to a bandwidth part identifier and a corresponding beam identifier. In some cases, the first control message is an example of a MAC layer message, such as a MAC-CE message. The index may correspond to a field that may be included in a DCI message transmission.

[0228] At 515, the UE 115-c may receive a second control message including an indication of an index in the set of indexes from the network entity 505. The second control message may be an example of a physical layer message, such as a DCI message. In some cases, the index may be indicated by a bwp-id field of the DCI.

[0229] At 520, the UE 115-c may identify the bandwidth part and the beam based on the index included in the second control message. For example, the UE 115-c may demap the indicated index based on the mapping indicated via the first control message. Thus, the bandwidth part identifier and the beam identifier (e.g., the satellite beam identifier) ​​may be identified based on the mapping.

[0230] At 525, the UE 115-c may communicate with the network entity 505 on the bandwidth portion in the beam mapped to the index indicated by the first control message. In some cases, this may include switching to a new bandwidth portion, performing beam switching, and so on.

[0231] According to another implementation, at 510, the UE 115-c may receive a first control message from the network entity 505, the first control message including an indication of a mapping of each TCI state 545 in the TCI state subset to a corresponding TCI code point 550. The TCI state 545 may include parameters for configuring a QCL relationship between one or two downlink reference signals and a downlink shared channel (e.g., PDSCH), a DMRS port of a downlink control channel (e.g., PDCCH), or a CSI-RS port of a CSI-RS resource. The TCI state 545 may signal the UE 115-d about which beam(s) to use to communicate with the network entity 505. The TCI code point 550 may be an example table (with a set of TCI states 545) of a finite size. The first control message may be an example of a MAC-CE message. The TCI state subset (e.g., a transmission configuration indicator state subset) may be an example of a TCI state including an indication of a beam identifier (e.g., a satellite beam identifier). The TCI state may have a type of "satellite beam index type", as described herein. These TCI states may be configured via RRC signaling.

[0232] At 515, the UE 115-c may receive a second control message including a TCI code point (e.g., an index to a code point / table) and an indication of a bandwidth portion identifier from the network entity 505. The second control message may be an example of a DCI message. The DCI message (e.g., the second control message) including the indication of the TCI code point and the bandwidth portion identifier may be included in a single transmission from the network entity 505 to the UE 115-c. Thus, upon receiving the second control message, the UE 115-c may identify the TCI state indicated by the TCI code point and identify the beam identified by the TCI state.

[0233] At 520, the UE 115-c may communicate with the network entity 505 on the bandwidth part corresponding to the indicated bandwidth part identifier and in the beam identified by the TCI state mapped to the transmission configuration indicator code point indicated by the first control message. In some cases, the communication may include switching to a new bandwidth part, performing beam switching, and the like.

[0234] Figure 6 An example of a process flow diagram 600 for supporting bandwidth portion switching through activation and signaling according to one or more aspects of the present disclosure is shown. In some examples, the process flow diagram 600 can implement aspects of the wireless communication system 100. The process flow diagram 600 includes a UE 115-d and a network entity 605, which can be as described with respect to Figures 1 to 4 Examples of corresponding devices described.

[0235] At 610, the UE 115-d may receive a control message including an indication of a TCI state identifier from the network entity 605. The control message may be an example of a MAC layer message (such as a MAC-CE message). The TCI state set may be configured at the UE 115-d using RRC messaging. The MAC-CE messaging may indicate a TCI state identifier of one of the configured TCI states (e.g., a transport configuration indicator state identifier).

[0236] At 615, the UE 115-d may determine that the TCI state corresponding to the TCI state identifier includes an indication of the satellite beam identifier. That is, the UE 115-d may identify the TCI state corresponding to the TCI state identifier and determine that the TCI state includes an indication of the satellite beam identifier. In some cases, this may include determining that the TCI state has a TCI state type of a satellite beam index type.

[0237] At 620, the UE 115-d may communicate with the network entity 605 using the satellite beam corresponding to the satellite beam identifier. In some cases, this may include performing beam switching. The UE 115-d may receive a DCI message indicating a bandwidth portion, and the UE 115-d may communicate with the network entity 605 using the bandwidth portion identified via the DCI message.
