Beam measurement report

Abstract

Methods, systems, and devices are described for wireless communication. In certain networks, a user equipment (UE) can switch between serving beams of a transmitting device that are associated with different bandwidth parts of a radio frequency spectrum. To improve aspects of beam measurement and selection, the UE can be configured to support various techniques for beam measurement according to the different bandwidth parts. For example, the UE can receive a beam measurement configuration associated with one or more beams and can monitor for reference signals associated with the beams using different bandwidth parts. The UE can determine channel quality for one or more of the beams based on the monitoring and transmit a beam measurement report to the network according to the beam measurement configuration. In certain examples, such a report can be transmitted based on the UE determining that an event condition is satisfied.

Technical Field

[0003] The following text pertains to wireless communications, including beam measurement reports. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can 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), LTE-A, or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ 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 Extended 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 supporting communication for multiple communication devices simultaneously, which may be referred to as User Equipment (UE).

[0005] In some systems, the UE can monitor reference signals to perform channel measurements, which can support the assessment of channel quality. In other cases, when monitoring reference signals that use different communication resources, the UE can identify degraded channel quality. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting beam measurement reporting, such as beam transmitters that may include satellites or other non-terrestrial equipment. In some networks, different beams may be associated with different bandwidth portions (e.g., to reduce interference between adjacent beams), and user equipment (UE) may perform beam handover accompanied by bandwidth portion handover based on various network factors. In some techniques, the UE may be configured to send status reports to the network to report the quality of a cell (e.g., serving cell) or cell pair (e.g., serving cell and neighboring cells) to reduce the likelihood of communication degradation for the UE. However, some techniques applied to cell measurement and handover may be associated with relatively high signaling overhead or power consumption, or may lack details of beam granularity within the cell. Therefore, to improve communication performance and reduce overhead, the UE may be configured by the network to support techniques for beam measurement reporting according to the examples disclosed herein.

[0007] In some examples, the UE may (e.g., from a network device) receive a beam measurement configuration associated with one or more beams, and each beam may be associated with a corresponding bandwidth portion of the radio frequency spectrum according to a beam frequency mapping. The UE may monitor one or more reference signals within the corresponding bandwidth portion according to the beam measurement configuration and send a beam measurement report based on a channel quality assessment of the monitored reference signals. In some examples, the beam measurement configuration may include indications of one or more event conditions, and the UE may send a beam measurement report based on determining that the event conditions are met (e.g., in a UE-initiated beam measurement report configuration). In some events, the UE may be prompted to generate a beam report based on determining that one or more beams meet a threshold beam quality. In some events, the UE may be prompted to generate a beam report based on a quality comparison between beams. In some events, the UE may be prompted to generate a beam report based on a block error rate associated with communication on the beam exceeding a threshold.

[0008] By configuring beam measurement reports for beams associated with different bandwidth portions (such as beams that can be adopted by network transmitters in a non-terrestrial network (NTN)), wireless communication systems can support improved flexibility and responsiveness for maintaining communication links using different beams associated with different frequency intervals. For example, the techniques described herein can achieve faster, more efficient, or more flexible beam selection, among other benefits, compared to techniques that do not consider adjacent beams configured according to different frequency intervals. Furthermore, the described techniques can be combined with event-based initiation of measurement reports by the UE, allowing the UE to proactively identify and generate beam measurement reports based on observed events associated with degraded beam quality. This can reduce power consumption or processing at the UE compared to other beam measurement techniques that do not involve UE-based measurement report initiation. These and other related improvements can be particularly beneficial in high-mobility scenarios such as NTNs, where movement of transmitting devices (e.g., satellites), receiving devices (e.g., UEs), or both can involve relatively frequent reselection of beams and corresponding bandwidth portions to maintain communication links.

[0065] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting beam measurement reporting, such as beam transmitters that may include satellites or other non-terrestrial equipment. In some networks, different beams may be associated with different bandwidth portions (e.g., to reduce interference between adjacent beams), and user equipment (UE) may perform beam handover accompanied by bandwidth portion handover based on various network factors. In some techniques, the UE may be configured to send status reports to the network to report the quality of a cell (e.g., serving cell) or cell pair (e.g., serving cell and neighboring cells) to reduce the likelihood of communication degradation for the UE. However, some techniques applied to cell measurement and handover may be associated with relatively high signaling overhead or power consumption, or may lack details of beam granularity within the cell. Therefore, to improve communication performance and reduce overhead, the UE may be configured by the network to support techniques for beam measurement reporting according to the examples disclosed herein.

[0066] In some examples, the UE may (e.g., from a network device) receive a beam measurement configuration associated with one or more beams, and each beam may be associated with a corresponding bandwidth portion of the radio frequency spectrum according to a beam frequency mapping. The UE may monitor one or more reference signals within the corresponding bandwidth portion according to the beam measurement configuration and may send a beam measurement report based on a channel quality assessment of the monitored reference signals. In some examples, the beam measurement configuration may include indications of one or more event conditions, and the UE may send a beam measurement report based on determining that the event conditions are met (e.g., in a UE-initiated beam measurement report configuration). In some events, the UE may be prompted to generate a beam report based on determining that one or more beams meet a threshold beam quality. In some events, the UE may be prompted to generate a beam report based on a quality comparison between beams. In some events, the UE may be prompted to generate a beam report based on a block error rate (BLER) associated with communication on the beam exceeding a threshold.

[0067] By configuring beam measurement reports for beams associated with different bandwidth portions (such as beams that can be adopted by network transmitters in a non-terrestrial network (NTN)), wireless communication systems can support improved flexibility and responsiveness for maintaining communication links using different beams associated with different frequency intervals. For example, the techniques described herein can achieve faster, more efficient, or more flexible beam selection, among other benefits, compared to techniques that do not consider adjacent beams configured according to different frequency intervals. Furthermore, the described techniques can be combined with event-based initiation of measurement reports by the UE, where the UE can proactively identify and generate beam measurement reports based on observed events associated with degraded beam quality. This can reduce power consumption or processing at the UE compared to other beam measurement techniques that do not involve UE-based measurement report initiation. These and other related improvements can be particularly beneficial in high-mobility scenarios such as NTNs, where the movement of transmitting devices (e.g., satellites), receiving devices (e.g., UEs), or both can involve relatively frequent reselection of beams and corresponding bandwidth portions to maintain communication links.

[0068] The aspects of this disclosure are initially described in the context of wireless communication systems and associated signaling and operation. These aspects are further illustrated and described by way of and reference to apparatus diagrams, system diagrams, and flowcharts relating to beam measurement reporting.

[0069] Figure 1 The figure illustrates an example of a wireless communication system 100 supporting beam measurement reporting according to aspects of this disclosure. 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 a Long Term Evolution (LTE) network, an LTE-Advanced (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 communication, ultra-reliable (e.g., mission-critical) communication, low latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0070] Base stations 105 can be distributed throughout a geographic area to form a wireless communication system 100 and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. The coverage area 110 can be an example of a geographic area on which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0071] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Some example UE 115s are... Figure 1 It is shown in the middle. For example... Figure 1 As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment).

[0072] Base station 105 may communicate with core network 130 or with each other, or both. For example, base station 105 may interface with core network 130 via one or more backhaul links 155 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) (or both) via backhaul links 155 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 155 may be or include one or more radio links.

[0073] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base transceiver station, radio base station, access point, radio transceiver, Node (node) B, eNodeB (eNB), next-generation NodeB or gigabit-NodeB (any of which may be referred to as gNB), home NodeB, home eNodeB or other suitable terms.

[0074] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, instruments, etc.

[0075] like Figure 1As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s that can sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0076] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 and one or more carriers. The term "carrier" can refer to a collection of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion (e.g., a bandwidth portion (BWP)) of a radio frequency spectrum band operating 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 coordinating the operation of the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0077] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0078] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of several defined bandwidths of a carrier used for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105 or UE 115, or both) may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base station 105 and / or UE 115 supporting 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, BWP) or all of the carrier bandwidth.

[0079] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are negatively correlated. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both). Therefore, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate that can be used for the UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity used for communication with the UE 115.

[0080] One or more parameter sets for a carrier can be supported, where the parameter sets may include subcarrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0081] The time interval used for base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, while N... f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resource can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0082] Each frame may include multiple 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 (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f Sampling period. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0083] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0084] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region (e.g., a control resource set (CORESET)) of the physical control channel can be defined by multiple symbol periods and can extend across the system bandwidth or a subset of the carrier's system bandwidth. One or more control regions (e.g., CORESET) can be configured for use by a set of UEs 115. For example, one or more UEs 115 can monitor or search control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner in one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set may include a common search space set configured to issue control information to multiple UEs 115 and a UE-specific search space set configured to issue control information to a specific UE 115.

[0085] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., via a carrier) and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), etc.). In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of geographic coverage area 110 on which a logical communication entity operates. The extent of such cells can range from small areas (e.g., structures, subsets of structures) to large areas, depending on various factors such as the capabilities of base station 105. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, etc.

[0086] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access to UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed or unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or limited access to UE 115 associated with the small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a home or office). Base station 105 can support one or more cells and can also support communication using one or more component carriers on one or more cells.

[0087] In some examples, base station 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0088] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical keypad calling (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0089] In some examples, UE 115 may also be able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without the involvement of base station 105.

[0090] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a Mobility Management Entity (MME), 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), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) for routing packets or interconnecting to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Operator IP service 150 can include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0091] Some network devices (such as base station 105) may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transmitting 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 headends and ANCs) or combined into a single network device (e.g., base station 105).

[0092] Wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is generally referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is from approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficiently to enable macrocells to serve UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0093] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region (also known as the centimeter-wave band) using a frequency band from 3 GHz to 30 GHz or in the extremely high frequency (EHF) region (e.g., from 30 GHz to 300 GHz) (also known as the millimeter-wave band) using a spectrum. In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, compared to SHF or UHF transmission, EHF transmission may suffer greater atmospheric attenuation and shorter distances during propagation. Transmissions can be made across one or more different frequency regions using the techniques disclosed herein, and the designated use of wavebands across these frequency regions may vary by country or regulatory body.

[0094] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on carrier aggregation configurations (e.g., LAA) that combine component carriers operating in licensed bands. Among other examples, operation in unlicensed spectrum can include downlink transmission, uplink transmission, P2P transmission, or D2D transmission.

[0095] Base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna accessory (such as an antenna tower). In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0096] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. This technique can be referred to as spatial multiplexing. For example, multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which multiple spatial layers are sent to the same receiving device, and multi-user MIMO (MU-MIMO) in which multiple spatial layers are sent to multiple devices.

[0097] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals communicating via antenna elements of an antenna array such that some signals propagating with respect to a specific orientation of the antenna array experience constructive interference while others experience destructive interference. Adjustments to the signals communicating via the antenna elements can include the transmitting or receiving device applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements can be defined by a beamforming weight set associated with a specific orientation (e.g., the antenna array relative to the transmitting or receiving device, or relative to some other orientation).

[0098] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Certain signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by transmitting devices, such as base station 105, or receiving devices, such as UE 115) the beam directions for subsequent transmissions or receptions by base station 105.

[0099] Certain signals, such as data signals associated with a specific receiving device, may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a 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 signals transmitted by base station 105 in different directions and may report to base station 105 an indication that UE 115 received a signal with the highest signal quality or with other acceptable signal quality.

[0100] In some examples, multiple beam directions can be used to perform transmission by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to the number of beams configured across the system bandwidth or one or more subbands. Base station 105 can transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which can be precoded or unprecoded. UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmission or reception by UE 115), or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0101] A receiving device (e.g., UE 115) may attempt multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may attempt multiple receiving directions by: receiving via different antenna subarrays; processing the received signal according to different antenna subarrays; receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets); or processing the received signal according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array, any of which can be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). The single receiving configuration may be aligned to a beam direction determined based on listening according to different receiving configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0102] Wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication over logical channels. The Medium Access Control (MAC) layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide support for the establishment, configuration, and maintenance of RRC connections between UE 115 and base station 105 or core network 130 for radio bearers supporting user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0103] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of data being correctly received through 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 MAC layer throughput under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in a previous symbol within that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0104] The wireless communication system 100 may also include one or more satellites 120 (e.g., in an NTN configuration) that can communicate with base station 105 or core network 130 via a gateway (e.g., a terrestrial terminal, an NTN gateway). Satellite 120 may also communicate with UE 115, which may include other high-altitude or terrestrial communication equipment. In various examples, satellite 120 itself may be an example of base station 105 (e.g., a payload supporting gNB processing), or satellite 120 may provide signal relay between base station 105 and UE 115 (e.g., in a transparent satellite configuration, where satellite 120 and a gateway may be configured together as a remote radio unit). Satellite 120 may be any suitable type of communication satellite configured to relay or otherwise support communication between different devices in the wireless communication system 100. Examples of satellite 120 include: space satellites, balloons, spacecraft, aircraft, drones, unmanned aerial vehicles, or other vehicles that can support communication from generally non-terrestrial, aerial, or elevated locations. In some examples, satellite 120 may be in geosynchronous or geostationary Earth orbit, low Earth orbit, or medium Earth orbit. Satellite 120 may be a multi-beam satellite configured to provide service for multiple service beam coverage areas within a configured geographic service area. Satellite 120 may be at any distance from the Earth's surface or other reference surface.

[0105] In some examples, the cell can be provided or established by satellite 120 as part of the NTN. In some cases, satellite 120 can perform the functions of base station 105, act as a bend-through satellite, or act as a regeneration satellite, or a combination thereof. In some examples, satellite 120 can be an example of a smart satellite or a satellite with intelligent or other communication processing capabilities. For example, a smart satellite can be configured to perform more functions than a regeneration satellite (e.g., it can be configured to perform a specific algorithm that is reprogrammed beyond the algorithm used in a regeneration satellite). In a bend-through transponder configuration, satellite 120 can be configured to receive signals from ground stations (e.g., gateway, base station 105, core network 130) and transmit those signals to different ground stations or terminals (e.g., UE 115, base station 105). In some cases, satellite 120 supporting bend-through transponder configuration can amplify signals or shift from uplink frequencies to downlink frequencies. In some examples, satellite 120 supporting regeneration transponder configuration can relay signals as in a bend-through transponder configuration, but can also use on-board processing to perform other functions. Examples of these other functions may include demodulating received signals, decoding received signals, recoding signals to be transmitted, or modulating signals to be transmitted, or combinations thereof. In some examples, satellite 120, which supports a bend transponder configuration or a regenerator transponder configuration, can receive signals from base station 105 and can relay those signals to UE 115 or base station 105, and vice versa.

[0106] According to the examples disclosed herein, wireless communication system 100 can be configured (e.g., via base station 105, via satellite 120) to provide UE 115 with a beam measurement configuration indicating parameters for monitoring reference signals of transmitted beams (e.g., different beams of a transmitting device), each transmitted beam being associated with a corresponding bandwidth portion. UE 115 can monitor one or more reference signals in the corresponding bandwidth portion according to the beam measurement configuration and send beam measurement reports (e.g., to base station 105, to satellite 120, to the network) based on a channel quality assessment of the monitored reference signals. In some examples, the beam measurement configuration may include indications of one or more event conditions, and UE 115 may send beam measurement reports based on determining that the event conditions are met (e.g., in a UE-initiated beam measurement report configuration). In some events, UE 115 may be prompted to generate a beam report based on determining that one or more beams meet a threshold beam quality. In some events, UE 115 may be prompted to generate a beam report based on a quality comparison between beams. In certain events, UE 115 may be prompted to generate a beam report based on a block error rate associated with communication on the beam exceeding a threshold.

[0107] By configuring beam measurement reports for beams associated with different bandwidth portions (such as beams that can be adopted by network transmitters in an NTN), the wireless communication system 100 can support improved flexibility and responsiveness for maintaining communication links using different beams associated with different frequency intervals. For example, the techniques described herein can achieve faster, more efficient, or more flexible beam selection, among other benefits, compared to techniques that do not consider adjacent beams configured according to different frequency intervals. Furthermore, the described techniques can be combined with event-based initiation of measurement reports by the UE 115, whereby the UE 115 can proactively identify and generate beam measurement reports based on observed events associated with degraded beam quality. This can reduce power consumption or processing at the UE 115 compared to other beam measurement techniques that do not involve UE-based measurement report initiation. These and other related improvements can be particularly beneficial in high-mobility scenarios (such as in NTN), where the movement of transmitting equipment (e.g., satellite 120), receiving equipment (e.g., UE 115), or both can involve relatively frequent reselection of beams and corresponding bandwidth portions to maintain communication links.

[0108] Figure 2 The figure illustrates an example of a wireless communication system 200 supporting beam measurement reporting for an NTN according to aspects of this disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a UE 115-a and a satellite 120-a. In some examples, the wireless communication system 200 may also include a gateway 210 or a base station 105-a or both. In various examples, one or more of the satellite 120-a, gateway 210, or base station 105-a, or various combinations thereof, may be connected to a network (such as a reference network). Figure 1 The core network 130 is described as a connection.

[0109] Satellite 120-a can be configured to support communications over geographic coverage area 110-a. Geographic coverage area 110-a can be located in a relatively fixed position (e.g., when satellite 120-a is in geostationary orbit or otherwise in a substantially fixed position in the air), or it can move or scan across locations (e.g., as a moving geographic coverage area, such as when satellite 120-a is in low Earth orbit or medium Earth orbit or otherwise moving in the air).

[0110] In some examples, satellite 120-a may be an example of a smart satellite or be configured to operate as a smart satellite, wherein satellite 120-a supports the ability to handle communications associated with coverage area 110-a (e.g., uplink communications, downlink communications, or both). In examples where satellite 120-a is configured to operate as a smart satellite, satellite 120-a may be an example of base station 105 as described herein (e.g., wherein satellite 120-a operates as a gNB or other type of base station), and satellite 120-a may or may not communicate with core network 130 via gateway 210 (e.g., via gateway communication link 215).

[0111] In some examples, satellite 120-a may be an example of a bend repeater or a regenerator repeater, or may be configured to operate as a bend repeater or a regenerator repeater, wherein satellite 120-a may operate as a relay between gateway 210 and one or more devices within geographic coverage area 110-a (e.g., relaying signals received from geographic coverage area 110-a via gateway communication link 215, relaying signals received from gateway 210 via gateway communication link 215 for transmission to devices in geographic coverage area 110-a). In examples where satellite 120-a is configured to operate as a bend repeater or a regenerator repeater, gateway 210, or a combination of gateway 210 and satellite 120-a, may be an example of base station 105 as described herein (e.g., wherein gateway 210 operates as a gNB or other type of base station, and a combination of satellite 120-a and gateway 210 operates as a gNB or other type of base station). In some examples, gateway 210 can communicate with base station 105 (e.g., base station 105-a, via communication link 220), and the combination of gateway 210 and satellite 120-a can be configured together as a remote radio unit of base station 105. In some examples, gateway 210 itself can be configured to operate as base station 105 (e.g., in a base station entity included in or otherwise co-located with gateway 210).

[0112] Satellite 120-a can be configured to support communications using multiple transmit or receive beams, where a beam can refer to a space or directional communication resource formed by or otherwise supported by the antenna array of satellite 120-a according to various beamforming techniques. For example, satellite 120-a can be configured to support multiple beams 230, which can refer to downlink beams (e.g., downlink transmit beams) supporting downlink communications 240 over geographic coverage area 110-a. Each beam 230 can be associated with a corresponding beam coverage area 235 (e.g., beam coverage area 235-a corresponds to beam 230-a, etc.), and multiple beams 230 or beam coverage areas 235 (e.g., beam coverage areas 235-a to 235-l) can be distributed across geographic coverage area 110-a. In some examples, beam 230 can support both downlink and uplink communications. In some examples, a first set of beams 230 (e.g., transmit beams) can support downlink communication, and a second set of beams 230 (e.g., receive beams, beams from different antenna arrays, beams associated with different directions or different beam coverage areas 235) can support uplink communication. In various examples, each of the beams 230 can be configured to operate as a different cell, or one or more cells can be configured according to a set of two or more beams 230, or all beams 230 can be configured to operate as a single cell.

[0113] Although the beam coverage area 235 is shown as nested hexagonal regions for illustrative purposes, the beams 230 may have some degree of overlap. For example, the transmitted signal energy from one beam 230 may be incident on one or more beam coverage areas 235 adjacent to the beam coverage area 235 corresponding to the transmitted beam 230 (e.g., the transmission of beam 230 associated with beam coverage area 235-e may be incident on one or more of beam coverage areas 235-a, 235-b, 235-d, 235-f, 235-g, or 235-h, and the transmission of beam 230 associated with beam coverage areas 235-a, 235-b, 235-d, 235-f, 235-g, or 235-h may be incident on beam coverage area 235-e, etc.). To reduce interference between adjacent or neighboring beams 230, each of the beams 230 can be configured with a corresponding bandwidth portion, such that neighboring beams 230 are configured for communication on different bandwidth portions. In one example, such frequency separation can be provided in the form of four bandwidth portions, each spanning a different range of the radio frequency spectrum (e.g., beams 1, 3, 7, and 9 are associated with BWP1, beams 2 and 8 with BWP2, beams 4, 6, 10, and 12 with BWP3, and beams 5 and 11 with BWP4).

[0114] In some examples, when UE 115-a is located within geographic coverage area 110-a, UE 115-a can establish a communication link with or via satellite 120-a. To maintain such a communication link, UE 115-a can switch between beams 230 relatively frequently due to the mobility of UE 115-a (e.g., where UE 115-a moves from one beam coverage area 235 to another), the mobility of satellite 120-a (e.g., where geographic coverage area 110-a or one or more beam coverage areas 235 move relative to UE 115-a), or various combinations thereof. In some examples, to support such beam switching or selection, UE 115-a can perform beam measurement operations to evaluate channel quality for communication via one or more beams 230. For example, UE 115-a can monitor or measure a reference signal 245 included in downlink communication 240 for a corresponding beam 230, which may include a beam identifier carried in or otherwise associated with the downlink communication 240.

[0115] In an NTN (such as a wireless communication system 200 supported by transmitting satellite 120-a), UE 115-a may perform beam switching relatively frequently based on factors such as: movement of the satellite beam coverage area 235 (e.g., 7 km / s for some low Earth orbit (LEO) satellites), the Doppler effect associated with the movement of satellite 120-a, the size of the beam coverage area 235 (e.g., 70 km by 300 km, which, combined with the movement rate of the beam coverage area 235, can be relatively small), or any combination thereof. In some examples, such beam switching may be performed more frequently or faster than cell handover in a terrestrial network. Furthermore, while the beam footprint may be relatively predictable for line-of-sight communications, it may be difficult to predict in non-line-of-sight communications (which may apply to communications between satellite 120-a and devices in geographic coverage area 110-a) (e.g., due to obstacles or reflection features such as buildings, canyons, mountains, or other signal blocking or signal alteration features), making beam measurement more important for the evaluation of beam 230 and the switching between beams 230.

[0116] According to certain techniques, UE 115 can be configured to send status reports to the network to report the quality of a cell (e.g., serving cell) or cell pair (e.g., serving cell and neighboring cells) to reduce the likelihood of communication degradation for UE 115. For example, UE 115 can be configured to perform measurements and reports for various cells based on reference signals. In some such techniques, UE 115 can periodically report Reference Signal Received Power (RSRP) based on Channel State Information Reference Signal (CSI-RS) or Synchronization Signal Block (SSB). In various examples, such reports can be sent periodically, semi-persistently, or aperiodically. Additionally or alternatively, Radio Resource Management (RRM) reports can be performed based on one or more cell-level measurements. In some examples, such techniques can be triggered based on various events indicating a change in the quality of the serving cell or one or more neighboring cells. However, such cell-level reporting can include the merging of beam statistics, so statistics for individual beams 230 may not be reported. In each example of a single cell associated with a beam coverage area 235, certain techniques used for cell-level measurements may therefore not report changes in channel quality using different beams 230 in the same cell, and may accordingly not be applicable to certain aspects of the network (such as NTN).

[0117] According to the examples disclosed herein, the wireless communication system 200 can be configured to support beam-level or beam-granular measurement reporting by the UE 115-a. This can be applied to scenarios such as NTN, where different beams 230 are associated with different bandwidth portions based on beam frequency mapping. For example, the wireless communication system 200 can implement various aspects of beam measurement configuration, which can configure channel state information (CSI) or other reference signal resources, beam measurement parameters, and beam reporting parameters for the UE 115-a. Such reporting can be periodic (e.g., configured via RRC signaling), semi-persistent (e.g., configured via RRC signaling and activated or deactivated via MAC signaling), non-periodic (e.g., network-initiated), or event-triggered (e.g., UE-initiated).

[0118] In some examples, the beam measurement configuration may include indications of various resources (e.g., CSI resources) on beam 230 or bandwidth portions, such as frequency resources or timing opportunities for monitoring CSI-RS, SBS, or other reference signals 245. In some examples, the beam measurement configuration may include conditions for initiating measurements of candidate beam 230, such as configuring UE115-a to begin measuring candidate or adjacent beam 230 if the channel quality measurement on the current beam 230 (e.g., the beam used or recently used to communicate with UE 115-a) is worse than (e.g., less than) a threshold. In some examples, the beam measurement configuration may include indications of which of one or more event conditions UE 115-a should use to initiate the generation or transmission of a beam measurement report, measurement-related parameters (such as which beams 230 to measure), or various parameters related to triggering conditions (such as hysteresis, offset, trigger time, filter coefficients, or any combination thereof). In some examples, beam measurement configuration may include an indication of which measurements should be included in the beam measurement report, such as RSRP, Reference Signal Received Quality (RSRQ), Signal-to-Interference-Noise Ratio (SINR), SNR, or certain other quantities or combinations thereof.

[0119] In the example of wireless communication system 200, UE 115-a can perform various measurements and reports according to such received beam measurement configurations. To perform measurements on different beams 230, UE 115-a can tune its radio to listen for or otherwise receive such reference signals 245. For example, to monitor the reference signal of beam 230 corresponding to beam coverage area 235-e (e.g., the current beam, the beam used for communication between satellite 120-a and UE 115-a), the radio can be tuned to BWP4. For the assessment of channel quality of adjacent beams, in order to monitor the reference signal of beam 230 associated with beam coverage area 235-a or 235-g, the radio of UE 115-a can be tuned to BWP 1; in order to monitor the reference signal of beam 230 associated with beam coverage area 235-b or 235-h, the radio of UE 115-a can be tuned to BWP 2; and in order to monitor the reference signal of beam 230 associated with beam coverage area 235-d or 235-f, the radio of UE 115-a can be tuned to BWP 3.

[0120] In some examples, UE 115-a may send channel quality reports to or via the same device or system transmitting beam 230 (e.g., satellite 120-a) or via the same device or system transmitting beam 230 (e.g., satellite 120-a). This may include transmissions to satellite 120-a (when satellite 120-a is used as base station 105 (e.g., in a payload configuration processed by gNB)), or transmissions via or through satellite 120-a to gateway 210 (via communication link 215) or to base station 105 (e.g., base station 105-a, via communication link 220) (in a transparent satellite configuration (e.g., when satellite 120-a operates as a bend or regenerator transponder)).

[0121] Figure 3 The figure illustrates an example of a process flow 300 supporting beam measurement reporting according to aspects of this disclosure. In some examples, process flow 300 may implement aspects of wireless communication systems 100 or 200. For example, process flow 300 may include network device 305, as referenced. Figure 1 and 2 The description may refer to satellite 120, a combination of satellite 120 and gateway 210, or base station 105. Process flow 300 may also include UE 310, which may be a reference... Figure 1 and 2 Example of UE 115 described.

[0122] At 315, network device 305 can transmit and UE 310 can receive with one or more beams (e.g., as referenced). Figure 2 The beam measurement configuration associated with the described beam 230. In some examples, each beam can be associated with a corresponding bandwidth portion of the radio frequency spectrum according to the beam frequency mapping (e.g., adjacent beams can be assigned to different bandwidth portions).

[0123] In various examples, beam measurement configurations can configure UE 310 to send beam measurement reports to network device 305 periodically (e.g., via RRC signaling), semi-persistently (e.g., via RRC signaling and activated or deactivated via MAC signaling), non-periodically (e.g., network-initiated), or event-triggered (e.g., UE-initiated). In some examples, the beam measurement configuration of 315 may include indications of CSI resources on various beam or bandwidth portions, such as those used for monitoring CSI-RS, SBS, or other reference signals (e.g., reference...). Figure 2The frequency resources or timing of the reference signal 245 described. In some examples, the beam measurement configuration of 315 may include conditions for starting to measure candidate beams, such as configuring UE310 to start measuring candidate or adjacent beams if the measurement on the current beam (e.g., the beam used or recently used to communicate with UE310) is worse than a threshold.

[0124] In some examples, the beam measurement configuration of 315 may include which of one or more event conditions the UE 310 should use to initiate the generation or transmission of a beam measurement report, measurement-related parameters (such as which beams to measure), or various parameters related to triggering conditions (such as hysteresis, offset, trigger time, filter coefficients, or any combination thereof). In some examples, the beam measurement configuration of 315 may include indications of which measurements should be included in the beam measurement report, such as RSRP, RSRQ, SINR, SNR, or certain other quantities or combinations thereof.

[0125] In some examples, the beam measurement configuration of UE 315 may utilize another RRM configuration with additional indications that indicate the configuration is used for beam-based measurements (e.g., a first indication of the radio resource management configuration and a second indication that the radio resource management configuration will be applied to measure one or more beams). In some examples, such additional indications may be included within each measurement object. In some examples, the beam measurement configuration of UE 315 may be indicated by a configuration field in an RRC reconfiguration message that configures UE 310 for beam-based measurements.

[0126] In some examples, the beam measurement configuration of 315 can configure UE 310 with a single trigger quantity (e.g., RSRP only), or UE 310 can be configured with multiple trigger quantities (e.g., RSRP and SINR) for beam measurement. In some examples, the beam measurement configuration of 315 can configure UE 310 with a single trigger event (e.g., an event condition), or UE 310 can be configured with multiple trigger events (e.g., a set of two or more event conditions) for beam measurement or for generating or sending measurement reports.

[0127] At 325, UE 310 may monitor (e.g., based on received beam measurement configuration) one or more reference signals associated with one or more beams, which may be associated with monitoring using one or more bandwidth portions associated with one or more beams according to beam frequency mapping. In some examples, UE 310 may monitor a first reference signal in a first bandwidth portion associated with the current beam (e.g., the active beam). In some examples, monitoring may include monitoring CSI-RS, SSB, or certain other reference signals, or a combination of reference signals.

[0128] At 330, UE 310 can determine the beam channel quality for one or more beams based on the monitoring at 325 (e.g., based on a measured reference signal). In some examples, UE 310 can determine the channel quality of a first beam based on monitoring a first bandwidth portion corresponding to a first reference signal for the first beam. UE 310 can use various beam quality metrics (e.g., related to the measurement of the reference signal) to determine the channel quality. For example, UE 310 can determine the channel quality for the first beam as a value of RSRP, RSRQ, SINR, or any combination thereof.

[0129] In some examples, UE 310 can be triggered to monitor or measure one or more beams, such as candidate beams or adjacent beams. For example, if the channel quality of the first beam meets a threshold channel quality (e.g., is worse than a threshold), UE 310 can measure the secondary (e.g., adjacent) beams and determine the corresponding channel quality metric.

[0130] In some examples (e.g., to support an example of event-triggered beam measurement reporting), at 335, UE 310 may determine that an event condition has been met based on determining the channel quality of one or more beams. For example, UE 310 may identify various events based on the channel quality of one or more beams, which may trigger the generation of a beam measurement report at UE 310, which can then be sent to network device 305.

[0131] In some examples (e.g., X1 event conditions), UE 310 may generate or send a beam measurement report based on determining that the channel quality for a first beam (e.g., the beam that UE 310 is currently monitoring) exceeds a threshold beam quality. For example, UE 310 may generate or send a beam measurement report based on determining the measured beam quality (Meas). c Subtracting the hysteresis value (Hyst) from the beam quality determines whether the event condition for X1 is met (e.g., if Meas...). c –If Hyst > threshold, then X1 is triggered). In some examples, if Meas c If +Hyst < threshold, then UE 310 can determine that the X1 event was canceled. In various examples, Meas c This can be a measurement of RSRP (e.g., in dBm), RSRQ, or SINR (e.g., in dB). In various examples, the hysteresis value can be configured as a value between 0 and x dB, where x > 0. In some examples, the trigger time can indicate a time period (e.g., a set of time periods) during or after which UE 310 can identify event X1, for example, if UE 310 determines conditional Meas. cIf the threshold value is true for the trigger time period, then UE 310 can trigger event X1.

[0132] In some examples (e.g., X2 event conditions), UE 310 may generate or transmit a beam measurement report based on determining that the channel quality for a first beam (e.g., the beam that UE 310 is currently monitoring) is less than a threshold beam quality or that the beam channel quality is worse than a threshold beam quality. For example, UE 310 may generate or transmit a beam measurement report based on determining the measured beam quality (Meas). c The beam quality is determined by adding a hysteresis value (Hyst) less than a threshold to determine if the event condition for X2 is met. (For example, if Meas...) c +Hyst < threshold, then X2 is triggered). In some examples, if Meas c If -Hyst > threshold, then UE 310 can determine that the X2 event was canceled. In various examples, Meas c This can be a measurement of RSRP (e.g., in dBm), RSRQ, or SINR (e.g., in dB). In various examples, the hysteresis value can be configured as a value between 0 and x dB, where x > 0. In some examples, the trigger time can indicate a time period (e.g., a set of time periods) during or after which the UE 310 can identify event X2, for example, if the UE 310 determines conditional Meas. c If +Hyst<threshold is true for the trigger time period, then UE 310 can trigger event X2.

[0133] In some examples (e.g., X3 event conditions), UE 310 may generate or send a beam measurement report based on determining that the channel quality for the second beam (e.g., an adjacent beam, or a beam different from the beam currently being monitored by UE 310) is greater than that for the first beam (e.g., the beam currently being monitored by UE 310). For example, UE 310 may generate or send a beam measurement report based on determining the measured beam quality (Meas) of an adjacent beam. n ) plus the reference signal specific offset of adjacent beams (O fn ) plus the beam-specific offset of adjacent beams (O bn Subtracting the hysteresis value (Hyst) from the beam quality (Meas) measured for the current beam is greater than the measured value for the current beam. c ) plus the reference signal specific offset of the current beam (O) fc ) plus the beam-specific offset of the current beam (O) bc Add an offset value to determine if the event condition for X3 is met. (For example, if Meas) n +O fn +O bn -Hyst>Meas c +O fc+O bc + offset, then X3 is triggered). In some examples, if Meas n +O fn +O bn +Hyst <Meas c +Of n +O bn + offset, then UE 310 can determine that the X3 event was canceled. In various examples, Meas n and Meas c This can be a measurement of RSRP (e.g., in dBm), RSRQ, or SINR (e.g., in dB). In some examples, the hysteresis value can be configured as a value between 0 and x dB, where x > 0. fn and O fc These can be offsets specific to reference signals associated with adjacent beams and the current beam, respectively, and can take into account differences in transmit power. bn and O bc These can be beam-specific offsets associated with adjacent beams and the current beam, respectively, and can take into account beam preferences within the network. In some examples, if UE 310 determines the conditional Meas... n +O fn +O bn -Hyst>Meas c +O fc +O bc If the +offset condition is true for the trigger time period, then UE 310 can trigger event X3.

[0134] In some examples (e.g., X4 event conditions), UE 310 may generate or send a beam measurement report based on determining that the channel quality for a second beam (e.g., an adjacent beam, or a beam different from the beam currently being monitored by UE 310) is greater than or better than a threshold beam quality. For example, UE 310 may generate or send a beam measurement report based on determining the measured beam quality (Meas) of an adjacent beam. n ) plus the reference signal specific offset of adjacent beams (O fn ) plus the beam-specific offset of adjacent beams (O bn Subtracting the hysteresis value (Hyst) from the threshold determines whether the event condition for X4 is met. (For example, if Meas...) n +O fn +O bn -Hyst>threshold, then X4 is triggered). In some examples, if Meas n +O fn +O bn If +Hyst < threshold, then UE 310 can determine that the X4 event was canceled. In various examples, Measn and Meas c This can be a measurement of RSRP (e.g., in dBm), RSRQ, or SINR (e.g., in dB). In some examples, the hysteresis value can be configured as a value between 0 and x dB, where x > 0. fn and O fc These can be offsets specific to reference signals associated with adjacent beams and the current beam, respectively, and can take into account differences in transmit power. bn and O bc These can be beam-specific offsets associated with adjacent beams and the current beam, respectively, and can take into account beam preferences within the network. In some examples, if UE 310 determines the conditional Meas... n +O fn +O bn If the threshold value is true for the trigger time period, then UE 310 can trigger event X4.

[0135] In some examples (e.g., X5 event conditions), UE 310 may generate or send a beam measurement report based on determining that the channel quality associated with a first beam (e.g., the beam UE 310 is currently monitoring) is worse than (e.g., less than) a first threshold, and the channel quality associated with a second beam (e.g., an adjacent beam, or a beam different from the beam UE 310 is currently monitoring) is better than (e.g., greater than) a second threshold. For example, UE 310 may determine the measured beam quality (Meas) of the current beam based on... c Adding the hysteresis value to the measured beam quality (Meas) of adjacent beams, which is less than the first threshold (threshold 1). n ) plus the reference signal specific offset of adjacent beams (O fn ) plus the beam-specific offset of adjacent beams (O bn Subtracting the hysteresis value (Hyst) from the value is greater than a second threshold to determine if the event condition for X5 is met. (For example, if Meas...) n +Hyst < threshold 1 and Meas n +O fn +O bn -If Hyst > threshold 2, then X5 is triggered. In some examples, if Meas n -Hyst>threshold 1 or Meas n +O fn +O bn If +Hyst < threshold 2, then UE 310 can determine that the X5 event was canceled. In various examples, Meas n and Meas cThis can be a measurement of RSRP (e.g., in dBm), RSRQ, or SINR (e.g., in dB). In some examples, the hysteresis value can be configured as a value between 0 and x dB, where x > 0. fn and O fc These can be offsets specific to reference signals associated with adjacent beams and the current beam, respectively, and can take into account differences in transmit power. bn and O bc These can be beam-specific offsets associated with adjacent beams and the current beam, respectively, and can take into account beam preferences within the network. In some examples, if UE 310 determines the conditional Meas... n +Hyst < threshold 1 and Meas n +O fn +O bn If threshold 2 is true for the trigger time period, then UE 310 can trigger event X5.

[0136] In some examples (e.g., X6 event conditions), UE 310 may generate or send a beam measurement report based on determining that the best subset (e.g., N beams) of a list of neighboring beams (e.g., M beams) becomes superior to the current beam by a threshold. For example, UE 310 may be located at the intersection or overlap of multiple beams or beam coverage areas (e.g., three beams). In some examples, UE 310 may receive signaling from network device 305 indicating a set of M neighboring beams. In some examples, UE 310 may base its report on the channel quality (Measuring Ability) of each beam within a subset of the N beams. 最佳 ) plus the reference signal specific offset of the best beam in the subset of N beams (O f,最佳 ) plus the beam-specific offset of the best beam in a subset of N beams (O b,最佳 Subtract the channel quality (Meas) whose hysteresis value is greater than the current beam's. c Add the reference signal specific offset of the current beam (Of) c ) plus the specific beam offset of the current beam (O) b,c Adding an offset determines whether the event condition for X6 is met (e.g., for each beam in a subset of N beams, if Meas 最佳 +O f,最佳 +O b,最佳 -Hyst>Meas c +O fc +O bc + offset, then X6 is triggered). In some examples, for M-N+1 beams, if Meas 最佳 +O f,最佳 +Ob 最佳+Hyst <Meas c +O fn +O bn + offset, then UE310 can determine that the X6 event was canceled. In various examples, Meas c and Meas 最佳 This can be a measurement of RSRP (e.g., in dBm), RSRQ, or SINR (e.g., in dB). In some examples, the hysteresis value can be configured as a value between 0 and x dB, where x > 0. f,最佳 and O b,最佳 It can be the corresponding reference signal-specific offset and beam-specific offset of the best beam in a subset of N adjacent beams. fc and O bc It can be O f,最佳 and O b,最佳 The current beam counterpart. In some examples, if UE 310 determines the conditional Meas for each beam in a subset of N beams. 最佳 +O f,最佳 +O b,最佳 -Hyst>Meas c +O fc +O bc If the offset is true for the trigger time period, then UE 310 can trigger event X6. In some examples where a subset of N beams equals the set of M beams, event condition X6 can be simplified to event condition X4 (e.g., UE 310 can generate a beam measurement report based on determining that the channel quality for an adjacent beam is greater than that for the current beam).

[0137] In some examples (e.g., X7 event conditions), UE 310 can generate or transmit beam measurement reports, beam failure instance (BFI) reports, out-of-sync reports, or any combination thereof, based on a block error rate (BLER) configuration. For example, UE 310 can determine the BLER value associated with communication on a first beam (e.g., the current beam) and can base its decision on whether the BLER associated with communication on the first beam is greater than a threshold BLER (e.g., BLER...). midThe BLER threshold is used to determine if the event condition for X7 is met. In some examples, the BLER threshold can be lower than the BLER threshold associated with determining a radio link failure. For example, in one configuration, the BLER threshold for synchronization reporting could be 2%, while the BLER threshold for asynchronous reporting (e.g., for determining a radio link failure) could be 10%, and the BLER threshold for meeting the X7 event condition could be 5%, where synchronization and asynchronous reports can be destined only for the RRC layer of UE 310 and not for network device 305 (e.g., not for gNB). In various examples, the BLER threshold can be adjusted to take into account HARQ feedback configurations, such as reducing the corresponding BLER threshold by a factor of 10 in a HARQ-enabled configuration or by a factor of 100 in a HARQ-free configuration. If UE 310 determines that the BLER for the measurement of the current beam exceeds the threshold BLER, UE 310 can determine that the event condition for X7 is met, and UE 310 can generate a beam measurement report.

[0138] At 350, UE 310 may send a beam measurement report to network device 305 (e.g., based on determining the channel quality of one or more beams at 330, and based on determining that one or more event conditions are met at 335). UE 310 may send the beam measurement report via RRC messages, MAC CE, or other uplink control information (UCI) (e.g., multiplexed with other information on PUSCH on PUCCH). In some examples, the report may include a beam ID (e.g., CSI Reference Signal Resource Indicator (CRI), Synchronization Signal Block (SSB) index, satellite beam ID). In some examples, the report may include a reporting quantity associated with the beam ID (e.g., L1-RSRP). In some examples, the report may include a list of beams sorted according to beam quality. In some examples, the report may include a configured beam measurement ID associated with a configured trigger event (e.g., one of events X1 to X7). In some cases, UE 310 can be configured with a single trigger event (e.g., one of X1–X7), in which case UE 310 can avoid reporting the trigger event ID or measurement ID. In other cases, UE 310 can be configured with multiple trigger events, multiple measurement objects, or both, and UE 310 can report the measurement ID.

[0139] In some examples, in order to send beam measurement reports, UE 310 may identify pre-configured resources, semi-persistently configured resources (e.g., resources whose activation may be based on UE 310's location within the beam coverage area), or dynamically allocated resources that UE 310 can use to send beam measurement reports. For example, UE 310 may receive a permission or configuration message from network device 305 indicating resources that UE 310 can use to send beam measurement reports at 350. In some examples, UE 310 may prioritize the transmission of beam status reports (e.g., via logical channel priority).

[0140] In the example where UE 310 sends a beam measurement report in an RRC message, UE 310 can reconfigure an existing RRC message or UE 310 can generate a new RRC message. In some examples, an existing RRC message for RRM (e.g., Layer 3) measurement reporting can be extended to include a beam measurement report. In some examples, key extensions to an existing RRC message can be defined for beam measurement reporting.

[0141] In some examples, at 350, UE 310 can use MAC CE to transmit beam measurement reports. For example, UE 310 can prioritize report transmissions (e.g., via logical channel priority), and MAC CE-based reports can have higher priority than other signaling (such as uplink data). In some examples, MAC CE can report beam measurement statistics for a variable number of beams (e.g., from 0 to N beams), which may include reporting smaller reports (e.g., a first part) and a full report using a variable MAC-CE format or using multiple fixed-size MAC CE formats. In some examples, if no uplink resources (e.g., UL SCH resources) are available for new transmissions or retransmissions, the beam measurement report MAC CE can trigger a scheduling request.

[0142] In some examples, at 350, UE 310 can use a bitmap report to send beam measurement reports. For example, RRC, MAC CE, or UCI reports can include bitmap reports for 0 to N beams. In some examples, the beam indexes can be the same order configured by the network for the list of beams to be measured. In some examples, a value "1" can indicate that a beam meets a configured criterion (e.g., RSRP for the beam is greater than a threshold), and a value "0" can indicate that a beam does not meet a configured criterion. In some examples, UE 310 can be configured with multiple trigger events or multiple measurement objects, and UE 310 can report a given measurement ID.

[0143] In some examples, depending on the resources available for sending beam measurement reports, UE 310 can be configured to support variable support sizes, and therefore variable details or content. For example, reports can be divided into multiple parts based on importance. In some examples, the first part may include the type of event, while the second part may include the amount of the report. The first part may involve a smaller number of bits but may be associated with a higher priority than the second part. Therefore, if the available resources are insufficient to send the complete report, or only sufficient to send the first part, UE 310 may only report the first part. In some examples, faster resources can be used to send more important parts of the beam measurement report. For example, UCI can be used to send the higher priority parts of the beam measurement information, while MAC CE or RRC messages can be used to send the lower priority parts of the beam measurement information. In some examples, UE 310 may multiplex beam measurement reports with RRC or MAC CE services as appropriate. In some examples, MAC CE can report statistics for a variable number of beams (e.g., from 0 to N beams), and the MAC CE format can be the same.

[0144] In some examples, network device 305 and UE 310 can be configured to support two-level reporting of beam measurements. For example, at 340, UE 310 can send an indication to network device 305 that an event condition has been met (e.g., in the first level of beam measurement reporting), and at 345, network device 305 can send, and UE 310 can receive, permission for resources to be used for sending the second level of beam measurement reporting. In some examples, the first level of two-level reporting can indicate the event type that triggers the event-based reporting (e.g., X1–X7). Based on the received indication that an event condition has been met at UE 310 (e.g., at 340), network device 305 can be prompted to prioritize the configuration of uplink resources for the second part of the beam measurement report. For example, network device 305 can send permission for resources that UE 310 can use to send measurements in the portion of the beam measurement report sent at 350 (e.g., at 345).

The information may be transmitted to other components of device 405. Receiver 410 may utilize a single antenna or a collection of antennas.

[0147] Transmitter 415 may provide components for transmitting signals generated by other components of device 405. In some examples, transmitter 415 may co-occur with receiver 410 in a transceiver module. Transmitter 415 may utilize a single antenna or a collection of antennas.

The circuitry may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described in this disclosure.

[0150] Additionally or alternatively, in some examples, the communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or various components thereof, may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or various components thereof, may be performed by a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or other programmable logic device.

[0151] In some examples, the communication manager 420 may be configured to use the receiver 410, the transmitter 415, or both, or otherwise cooperate with them to perform various operations (e.g., receiving, monitoring, sending).

[0153] By including or configuring the communication manager 420 according to the examples disclosed herein, the device 405 can support improved techniques for beam measurement and mobility in wireless communication systems. For example, by configuring beam measurement reports for beams associated with different bandwidth portions (such as beams that can be adopted by network transmitters in an NTN), the communication manager 420 can support improved flexibility and responsiveness for maintaining communication links using different beams associated with different frequency intervals. For example, the techniques described herein can achieve faster, more efficient, or more flexible beam selection, among other benefits, compared to techniques that do not take into account adjacent beams configured according to different frequency intervals. Furthermore, the described techniques can be combined with event-based initiation of measurement reports by the device 405, where the device 405 can autonomously identify and generate beam measurement reports based on observed events associated with degraded beam quality, which can reduce power consumption or processing at the device 405 compared to other beam measurement techniques that do not involve UE-based measurement report initiation. These and other related improvements can be particularly beneficial in high-mobility scenarios such as NTN, where the movement of transmitting equipment (e.g., satellite 120), receiving equipment (e.g., device 405), or both can involve relatively frequent reselection of beams and corresponding bandwidth portions to maintain communication links.

[0223] Figure 11A diagram illustrates a system 1100 including a device 1105 supporting beam measurement reporting according to aspects of this disclosure. Device 1105 may be a network device as described herein, device 805, device 905, satellite 120, gateway 210, a combination of satellite 120 and gateway 210, or an example of base station 105, or include components thereof. Device 1105 may wirelessly communicate with one or more base stations 105, UE 115, or any combination thereof. Device 1105 may include components for bidirectional voice and data communication, including components for transmitting and receiving communications, including a communication manager 1110, a network communication manager 1115, a transceiver 1120, an antenna 1125, a memory 1130, code 1135, a processor 1140, and an inter-station communication manager 1145. These components may communicate electronically or be otherwise coupled (e.g., operatively coupled, communicatively coupled, functionally coupled, electronically coupled, electrically coupled) via one or more buses (e.g., bus 1150).

[0224] The network communication manager 1115 can manage communication with the core network (e.g., via one or more wired backhaul links). For example, the network communication manager 1115 can manage the delivery of data communication for client devices (such as one or more UEs 115).

[0225] In some cases, device 1105 may include a single antenna 1125. However, in other cases, the device may have more than one antenna 1125, which may be able to transmit or receive multiple wireless transmissions simultaneously. Transceiver 1120 may communicate bidirectionally via one or more antennas 1125 as described herein, a wired or wireless link. For example, transceiver 1120 may represent a wireless transceiver and may communicate bidirectionally with another wireless transceiver. Transceiver 1120 may also include a modem to modulate packets and provide modulated packets to one or more antennas 1125 for transmission, and to demodulate packets received from one or more antennas 1125. Transceiver 1120, or transceiver 1120 and one or more antennas 1125, may be an example of transmitter 815, transmitter 915, receiver 810, receiver 910, or any combination thereof or components thereof as described herein.

[0226] Memory 1130 may include random access memory (RAM) and read-only memory (ROM). Memory 1130 may store computer-readable, computer-executable code 1135, including instructions that, when executed by processor 1140, cause device 1105 to perform the various functions described herein. Code 1135 may be stored in a non-transitory computer-readable medium, such as system memory or other types of memory. In some cases, code 1135 may not be directly executable by processor 1140, but may cause the computer (e.g., when compiled and executed) to perform the functions described herein. In some cases, memory 1130 may contain a BIOS, which controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0227] Processor 1140 may include intelligent hardware devices (e.g., general-purpose processors, DSPs, central processing units (CPUs), microcontrollers, ASICs, FPGAs, programmable logic devices, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some cases, processor 1140 may be configured to use a memory controller to operate a memory array. In other cases, the memory controller may be integrated into processor 1140. Processor 1140 may be configured to execute computer-readable instructions stored in memory (e.g., memory 1130) to cause device 1105 to perform various functions (e.g., functions or tasks supporting beam measurement reporting).

[0228] Inter-site communication manager 1145 can manage communication with other base stations 105 and may include a controller or scheduler for controlling communication with UEs 115 that cooperate with other base stations 105. For example, inter-site communication manager 1145 can coordinate the scheduling of transmissions to UEs 115 for various interference mitigation techniques, such as beamforming or joint transmission. In some examples, inter-site communication manager 1145 may provide an X2 interface within LTE / LTE-A wireless communication network technology to provide communication between base stations 105.

[0229] According to the examples disclosed herein, the communication manager 1110 may support wireless communication at a network device. For example, the communication manager 1110 may be configured to provide or support components for transmitting beam measurement configurations associated with one or more beams of the network device, wherein each of the one or more beams is associated with a corresponding bandwidth portion of one or more bandwidth portions of a radio frequency spectrum according to a beam frequency mapping. The communication manager 1110 may be configured to provide or support components for transmitting reference signals using one or more beams, wherein transmitting the reference signals includes transmitting a corresponding reference signal for each of the one or more beams using a corresponding bandwidth portion associated with the beam according to a beam frequency mapping. The communication manager 1110 may be configured to provide or support components for receiving beam measurement reports based on beam measurement configurations from a UE based on transmitting reference signals using one or more beams.

[0230] By including or configuring the communication manager 1110 according to the examples disclosed herein, the device 1105 can support improved techniques for beam measurement and mobility in wireless communication systems. For example, by configuring the UE 115 for beam measurement reporting for beams associated with different bandwidth portions (such as beams that can be adopted by network transmitters in an NTN), the communication manager 1110 can support improved flexibility and responsiveness for maintaining a communication link with the UE 115 using different beams associated with different frequency intervals. For example, the techniques described herein can achieve faster, more efficient, or more flexible beam selection, among other benefits, compared to techniques that do not consider adjacent beams configured according to different frequency intervals. Furthermore, the described techniques can be combined with event-based initiation of measurement reports by the UE 115, whereby the UE 115 can proactively identify and generate beam measurement reports based on observed events associated with degraded beam quality. This can reduce power consumption or processing at the UE 115 compared to other beam measurement techniques that do not involve UE-based measurement report initiation. These and other related improvements can be particularly beneficial in high-mobility scenarios such as NTN, where the movement of the transmitting device (e.g., device 1105), the receiving device (e.g., UE 115), or both can involve relatively frequent reselection of beams and corresponding bandwidth portions to maintain the communication link. Accordingly, by supporting more reliable, flexible, or diverse technologies for maintaining the communication link, including the communication manager 1110, the user experience associated with UE 115 can be improved.

[0231] In some examples, the communication manager 1110 may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise cooperating with the transceiver 1120, one or more antennas 1125, or any combination thereof. Although the communication manager 1110 is illustrated as a separate component, in some examples, one or more functions described with reference to the communication manager 1110 may be supported or performed by the processor 1140, memory 1130, code 1135, or any combination thereof. For example, code 1135 may include instructions that can be executed by the processor 1140 to cause the device 1105 to perform various aspects of beam measurement reporting as described herein, or the processor 1140 and memory 1130 may be otherwise configured to perform or support such operations.
