Technical Field

[0004] Aspects of the present disclosure relate generally to wireless communications and, more particularly, to techniques and apparatus for improved beam management. Background Art

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0006] A wireless network may include several base stations (BSs) that can support communications for several user equipments (UEs). The UE may communicate with the BS via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receiving Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0007] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global level. NR (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR and other radio access technologies are still useful. Summary of the invention

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

[0078] It should be noted that while various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).

[0079] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, a B node, an e B node (eNB), a gNB, a 5G B node (NB), an access point, a transmission reception point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0080] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0081] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0082] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.

[0083] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0084] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0085] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0086] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network) via, for example, a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0087] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0088] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0089] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) and / or may communicate using an operating band having a second frequency range (FR2), the first frequency range (FR1) may span 410 MHz to 7.125 GHz, and the second frequency range (FR2) may span 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz band". Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise specifically stated, it should be understood that the term sub-"6 GHz," etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the term "millimeter wave," etc., if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0090] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described herein. Figure 1 Examples described.

[0091] Figure 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0092] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0093] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0094] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0095] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmission and / or reception components (such as Figure 2 One or more antenna elements of one or more components).

[0096] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, where applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0097] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0098] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the base station 110 may perform one or more techniques associated with improved beam management, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 8 800 and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include: a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example Figure 8 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions.

[0099] In some aspects, UE 120 may include: means for measuring a beam according to a measurement configuration to determine a channel condition value for the beam; means for modifying the channel condition value based at least in part on at least one of one or more beam characteristics, a derivation of a beamforming gain value, or an estimate of the beamforming gain value; means for transmitting a measurement report indicating the modified channel condition value to a base station; and the like. In some aspects, such means may include in conjunction with Figure 2 One or more components of the UE 120 are depicted, such as the controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0100] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described herein. Figure 2 Examples described.

[0101] Figure 3 3 is a diagram illustrating an example beamforming architecture 300 that supports beamforming for millimeter wave communications in accordance with the present disclosure. In some aspects, the architecture 300 can implement aspects of the wireless network 100. In some aspects, the architecture 300 can be implemented in a transmitting device (e.g., a first wireless communication device, UE, or base station) and / or a receiving device (e.g., a second wireless communication device, UE, or base station), as described herein.

[0102] Broadly, Figure 3 300 is a diagram illustrating example hardware components of a wireless communication device according to certain aspects of the present disclosure. The illustrated components may include those components that can be used for antenna element selection and / or beamforming for wireless signal transmission. There are many architectures for antenna element selection and phase shifting, only one example of which is illustrated here. Architecture 300 includes a modem (modulator / demodulator) 302, a digital-to-analog converter (DAC) 304, a first mixer 306, a second mixer 308, and a splitter 310. Architecture 300 also includes a plurality of first amplifiers 312, a plurality of phase shifters 314, a plurality of second amplifiers 316, and an antenna array 318 including a plurality of antenna elements 320.

[0103] Transmission lines or other waveguides, wires, traces, etc. are shown connecting the various components to illustrate how signals to be transmitted can travel between the components. Reference numerals 322, 324, 326, and 328 indicate areas in the architecture 300 where different types of signals travel or are processed. Specifically, reference numeral 322 indicates an area where digital baseband signals travel or are processed, reference numeral 324 indicates an area where analog baseband signals travel or are processed, reference numeral 326 indicates an area where analog intermediate frequency (IF) signals travel or are processed, and reference numeral 328 indicates an area where analog radio frequency (RF) signals travel or are processed. The architecture also includes a local oscillator A 330, a local oscillator B 332, and a beamforming manager 334.

[0104] Each of the antenna elements 320 may include one or more sub-elements for radiating or receiving RF signals. For example, a single antenna element 320 may include a first sub-element that is cross-polarized with a second sub-element, which may be used to independently transmit a cross-polarized signal. The antenna elements 320 may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or other patterns. The spacing between the antenna elements 320 may allow signals with desired wavelengths that are separately transmitted by the antenna elements 320 to interact or interfere (e.g., to form a desired beam). For example, given an expected range of wavelengths or frequencies, the spacing may provide a quarter wavelength, half a wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements 320 to allow interaction or interference of signals transmitted by separate antenna elements 320 within the expected range.

[0105] The modem 302 processes and generates a digital baseband signal, and may also control the operation of the DAC 304, the first and second mixers 306, 308, the splitter 310, the first amplifier 312, the phase shifter 314, and / or the second amplifier 316 to transmit the signal via one or more or all of the antenna elements 320. The modem 302 may process the signal and control the operation according to a communication standard (such as the wireless standard discussed herein). The DAC 304 may convert the digital baseband signal received from the modem 302 (and to be transmitted) into an analog baseband signal. The first mixer 306 uses the local oscillator A 330 to up-convert the analog baseband signal into an analog IF signal within the IF. For example, the first mixer 306 may mix the signal with an oscillating signal generated by the local oscillator A 330 to "move" the baseband analog signal to the IF. In some cases, some processing or filtering (not shown) may be performed at the IF. The second mixer 308 uses local oscillator B 332 to up-convert the analog IF signal to an analog RF signal. Similar to the first mixer, the second mixer 308 can mix the signal with an oscillating signal generated by local oscillator B 332 to "move" the IF analog signal to RF, or the frequency at which its signal is to be transmitted or received. The modem 302 and / or the beamforming manager 334 can adjust the frequency of local oscillator A 330 and / or local oscillator B 332 so that the desired IF and / or RF frequencies are generated and used to facilitate the processing and transmission of signals within the desired bandwidth.

[0106] In the illustrated architecture 300, the signal up-converted by the second mixer 308 is split or copied into multiple signals by the splitter 310. The splitter 310 in the architecture 300 splits the RF signal into multiple identical or almost identical RF signals. In other examples, any type of signal (including baseband digital signal, baseband analog signal or IF analog signal) can be split. Each of these signals can correspond to an antenna element 320, and the signal passes through an amplifier 312, 316, a phase shifter 314 and / or other elements corresponding to the corresponding antenna element 320 or is processed by these elements to be provided to the corresponding antenna element 320 of the antenna array 318 or transmitted by the corresponding antenna element 320 of the antenna array 318. In one example, the splitter 310 can be an active splitter, which is connected to a power supply and provides some gain so that the RF signal leaving the splitter 310 is at a power level equal to or greater than the signal entering the splitter 310. In another example, the splitter 310 is a passive splitter that is not connected to a power source, and the RF signal exiting the splitter 310 may be at a lower power level than the RF signal entering the splitter 310 .

[0107] After being split by splitter 310, the resulting RF signal can enter an amplifier (such as, first amplifier 312) or phase shifter 314 corresponding to antenna element 320. The first and second amplifiers 312, 316 are illustrated with dotted lines because in some aspects, one or both of them may not be necessary. In some aspects, both the first amplifier 312 and the second amplifier 316 exist. In some aspects, both the first amplifier 312 and the second amplifier 316 do not exist. In some aspects, one of the two amplifiers 312, 316 exists, but the other does not exist. As an example, if splitter 310 is an active splitter, the first amplifier 312 may not be used. As a further example, if phase shifter 314 is an active phase shifter that can provide gain, the second amplifier 316 may not be used.

[0108] The amplifiers 312, 316 can provide a desired level of positive gain or negative gain. Positive gain (positive dB) can be used to increase the amplitude of a signal radiated by a particular antenna element 320. Negative gain (negative dB) can be used to reduce the amplitude of a signal radiated by a particular antenna element 320 and / or suppress its radiation. Each of the amplifiers 312, 316 can be independently controlled (e.g., by the modem 302 or the beamforming manager 334) to provide independent control of the gain for each antenna element 320. For example, the modem 302 and / or the beamforming manager 334 can have at least one control line connected to each of the splitter 310, the first amplifier 312, the phase shifter 314, and / or the second amplifier 316, which can be used to configure the gain to provide a desired amount of gain for each component and therefore each antenna element 320.

[0109] The phase shifter 314 may provide a configurable phase shift or phase offset to the corresponding RF signal to be transmitted. The phase shifter 314 may be a passive phase shifter that is not directly connected to a power source. A passive phase shifter may introduce some insertion loss. The second amplifier 316 may enhance the signal to compensate for the insertion loss. The phase shifter 314 may be an active phase shifter connected to a power source so that the active phase shifter provides a certain amount of gain or prevents insertion loss. The setting of each phase shifter 314 is independent, which means that each phase shifter can be independently set to provide a desired phase shift amount or the same phase shift amount or some other configuration. The modem 302 and / or the beamforming manager 334 may have at least one control line connected to each phase shifter 314, and the at least one control line may be used to configure the phase shifter 314 to provide a desired phase shift amount or phase offset amount between each antenna element 320.

[0110] In the illustrated architecture 300, the RF signal received by the antenna element 320 is provided to one or more first amplifiers 356 to enhance the signal strength. The first amplifier 356 may be connected to the same antenna array 318 (e.g., for time division duplex (TDD) operation). The first amplifier 356 may be connected to different antenna arrays 318. The enhanced RF signal is input to one or more phase shifters 354 to provide a configurable phase shift or phase offset for the corresponding received RF signal to achieve reception via one or more Rx beams. The phase shifter 354 may be an active phase shifter or a passive phase shifter. The settings of each phase shifter 354 are independent, which means that each phase shifter can be independently set to provide a desired phase shift amount or the same phase shift amount or some other configuration. The modem 302 and / or the beamforming manager 334 may have at least one control line connected to each phase shifter 354, and the at least one control line may be used to configure the phase shifter 354 to provide a desired phase shift or phase offset between the antenna elements 320 to enable reception via one or more Rx beams.

[0111] The output of phase shifter 354 may be input to one or more second amplifiers 352 for signal amplification of the phase-shifted received RF signal. Second amplifier 352 may be individually configured to provide a configured gain amount. Second amplifier 352 may be individually configured to provide a gain amount to ensure that the signals input to combiner 350 have the same amplitude. Amplifiers 352 and / or 356 are illustrated with dotted lines because they may not be necessary in some aspects. In some aspects, both amplifier 352 and amplifier 356 exist. On the other hand, both amplifier 352 and amplifier 356 do not exist. In other aspects, one of amplifiers 352, 356 exists, but the other does not exist.

[0112] In the illustrated architecture 300, the signals output by the phase shifter 354 (via the amplifier 352 when there is an amplifier 352) are combined in the combiner 350. The combiner 350 in the architecture 300 combines the RF signals into one signal. The combiner 350 can be a passive combiner (e.g., not connected to a power supply), which may result in some insertion loss. The combiner 350 can be an active combiner (e.g., connected to a power supply), which may result in some signal gain. When the combiner 350 is an active combiner, it can provide different (e.g., configurable) gain amounts for each input signal so that the input signals have the same amplitude when combined. When the combiner 350 is an active combiner, the combiner 350 may not need a second amplifier 352 because the active combiner can provide signal amplification.

[0113] The output of combiner 350 is input to mixers 348 and 346. Mixers 348 and 346 typically down-convert received RF signals using inputs from local oscillators 372 and 370, respectively, to produce intermediate or baseband signals carrying coded and modulated information. The outputs of mixers 348 and 346 are input to analog-to-digital converter (ADC) 344 for conversion to digital signals. The digital signals output from ADC 344 are input to modem 302 for baseband processing, such as decoding, deinterleaving, etc.

[0114] The architecture 300 is provided only by way of example to illustrate an architecture for transmitting and / or receiving signals. In some cases, the architecture 300 and / or each part of the architecture 300 can be repeated multiple times within the architecture to accommodate or provide any number of RF chains, antenna elements and / or antenna panels. In addition, numerous replacement architectures are possible and contemplated. For example, although only a single antenna array 318 is shown, two, three or more antenna arrays may be included, each with its own corresponding amplifier, phase shifter, splitter, mixer, DAC, ADC and / or modem. One or more. For example, a single UE may include two, four or more antenna arrays for transmitting or receiving signals at different physical locations on the UE or in different directions.

[0115] In addition, mixers, splitters, amplifiers, phase shifters and other components can be located in different signal type areas (e.g., represented by different reference numerals in reference numerals 322, 324, 326, 328) in different implementation architectures. For example, in different examples, splitting the signal to be transmitted into multiple signals can occur at analog RF, analog IF, analog baseband or digital baseband frequencies. Similarly, amplification and / or phase shifting can also occur at different frequencies. For example, in some aspects, one or more of splitter 310, amplifier 312, 316 or phase shifter 314 can be located between DAC 304 and first mixer 306, or between first mixer 306 and second mixer 308. In one example, the functions of one or more components can be combined into one component. For example, phase shifter 314 can perform amplification to include or replace first amplifier 312 and / or second amplifier 316. As another example, phase shifting can be implemented by second mixer 308 to eliminate the need for separate phase shifter 314. This technique is sometimes referred to as local oscillator (LO) phase shifting. In some aspects of this configuration, there may be multiple IF to RF mixers within the second mixer 308 (e.g., for each antenna element chain), and the local oscillator B 332 may provide a different local oscillator signal (with a different phase offset) to each IF to RF mixer.

[0116] The modem 302 and / or the beamforming manager 334 can control one or more of the other components 304 to 372 to select one or more antenna elements 320 and / or to form a beam for transmitting one or more signals. For example, the antenna elements 320 can be individually selected for transmission of a signal (or signals) or deselected by controlling the amplitude of one or more corresponding amplifiers (such as the first amplifier 312 and / or the second amplifier 316). Beamforming includes generating beams using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are phase-shifted relative to each other. The formed beams may carry physical or higher layer reference signals or information. When each of the multiple signals is radiated from the corresponding antenna element 320, the radiated signals interact, interfere (constructively and destructively) and amplify each other to form the resulting beam. The shape (such as the amplitude, width, and / or presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array 318) can be dynamically controlled by modifying the phase shift or phase offset imparted by the phase shifter 314 and the amplitude imparted by the amplifiers 312, 316 of the multiple signals relative to each other. The beamforming manager 334 can be partially or fully located within one or more other components of the architecture 300. For example, in some aspects, the beamforming manager 334 can be located within the modem 302.

[0117] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described herein. Figure 3 Examples described.

[0118] Figure 4 4 is a diagram illustrating an example 400 of a synchronization signal (SS) hierarchy according to the present disclosure. Figure 4 As shown in , the SS hierarchy may include an SS burst set 405, which may include multiple SS bursts 410 (shown as SS Burst 0 through SS Burst N-1, where N is the maximum number of repetitions of the SS burst 410 that may be transmitted by the base station). As further shown, each SS burst 410 may include one or more SS blocks (SSBs) 415 (shown as SSB 0 through SSB M-1), where M is the maximum number of SSBs 415 that may be carried by the SS burst 410. In some aspects, different SSBs 415 may be beamformed differently (e.g., transmitted using different beams) and may be used for beam management, beam selection, etc. (e.g., as part of an initial network access procedure). The SS burst set 405 may be transmitted by a wireless node (e.g., base station 110) periodically, such as every X milliseconds, as shown. Figure 4 In some aspects, SS burst set 405 may have a fixed or dynamic length. Figure 4In some cases, SS burst set 405 or SS burst 410 may be referred to as a discovery reference signal (DRS) transmission window, an SSB measurement time configuration (SMTC) window, or the like.

[0119] In some aspects, the SSB 415 may include resources that carry a primary synchronization signal (PSS) 420, a secondary synchronization signal (SSS) 425, a physical broadcast channel (PBCH) 430, and the like. In some aspects, multiple SSBs 415 are included in an SS burst 410 (e.g., transmissions on different beams), and the PSS 420, SSS 425, and / or PBCH 430 may be the same across each SSB 415 of an SS burst 410. In some aspects, a single SSB 415 may be included in an SS burst 410. In some aspects, the SSB 415 may be at least four symbols (e.g., OFDM symbols) in length, with each symbol carrying one or more of the PSS 420 (e.g., occupying one symbol), the SSS 425 (e.g., occupying one symbol), and / or the PBCH 430 (e.g., occupying two symbols). In some aspects, the SSB 415 may be referred to as an SS / PBCH block.

[0120] In some aspects, the symbols of SSB 415 are consecutive, such as Figure 4 . In some aspects, the symbols of the SSB 415 are non-consecutive. Similarly, in some aspects, one or more SSBs 415 of the SS burst 410 may be transmitted in contiguous radio resources (e.g., contiguous symbols) during one or more time slots. Additionally or alternatively, one or more SSBs 415 of the SS burst 410 may be transmitted in non-consecutive radio resources.

[0121] In some aspects, the SS burst 410 may have a burst periodicity, and the SSBs 415 of the SS burst 410 may be transmitted by a wireless node (e.g., base station 110) according to the burst periodicity. In this case, the SSBs 415 may be repeated during each SS burst 410. In some aspects, the SS burst set 405 may have a burst set periodicity, whereby each SS burst 410 of the SS burst set 405 is transmitted by the wireless node according to a fixed burst set periodicity. In other words, the SS burst 410 may be repeated during each SS burst set 405.

[0122] In some aspects, the SSB 415 may include an SSB index, which may correspond to a beam for carrying the SSB 415. The UE 120 may monitor and / or measure the SSB 415 using different receive (Rx) beams during an initial network access procedure. Based at least in part on the monitoring and / or measurement, the UE 120 may indicate to the base station 110 one or more SSBs 415 having the best signal parameters (e.g., reference signal received power (RSRP) parameters, etc.). The base station 110 and the UE 120 may use the indicated one or more SSBs 415 to select one or more beams for communication between the base station 110 and the UE 120 (e.g., for random access channel (RACH) procedures, etc.). Additionally or alternatively, the UE 120 may use the SSB 415 and / or the SSB index to determine the cell timing of a cell (e.g., a serving cell) via which the SSB 415 is received.

[0123] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.

[0124] Figure 5 is a diagram illustrating an example 500 of an NR non-standalone (NSA) architecture according to the present disclosure.

[0125] like Figure 5 As shown in , in NR or 5G NSA mode, UE 120 can communicate with both eNB (e.g., 4G base station 110) and gNB (e.g., 5G base station 110), and eNB and gNB can communicate with 4G / LTE core network (shown as Evolved Packet Core (EPC) including Mobility Management Entity (MME), Packet Data Network Gateway (PGW), Serving Gateway (SGW), etc.) (e.g., directly or indirectly). Figure 5 In the present invention, PGW and SGW are collectively referred to as P / SGW. In some aspects, the eNB and gNB may be co-located at the same base station 110. In some aspects, the eNB and gNB may be included in different base stations 110 (eg, may not be co-located).

[0126] like Figure 5As further shown in , in some aspects, a wireless network that permits operation in 5G NSA mode may permit such operation by using a primary cell group (MCG) for a first RAT (e.g., LTE RAT, 4G RAT, etc.) and a secondary cell group (SCG) for a second RAT (e.g., NR RAT, 5G RAT, etc.). In this case, the UE 120 may communicate with the eNB via the MCG and may communicate with the gNB via the SCG. In some aspects, the MCG may anchor the network connection between the UE 120 and the 4G / LTE core network (e.g., for mobility, coverage, control plane information, etc.), and the SCG may be added as an additional bearer to increase throughput (e.g., for data traffic, user plane information, etc.). In some aspects, the gNB and the eNB may not communicate user plane information between each other.

[0127] In some aspects, the 5G NSA mode may be an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA)-NR dual connectivity (ENDC) mode or an NR-E-UTRA dual connectivity (NEDC) mode. In some aspects, a UE 120 operating in ENDC mode or NEDC mode may have dual connectivity with an LTE base station 110 (e.g., an eNB) and an NR base station 110 (e.g., a gNB).

[0128] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described herein. Figure 5 Examples described.

[0129] In some wireless networks, the base station may configure the UE to measure and report channel condition values ​​for different beams so that the base station can perform one or more beam management procedures. For example, the UE may measure the beam of the serving cell according to the measurement configuration and may report the measurements to the base station. Similarly, the UE may measure the beams of one or more neighbor cells (e.g., of the same RAT or different RATs) according to the measurement configuration and may report the measurements to the base station. The base station 110 may receive the reported measurements from the UE and perform one or more beam management procedures. For example, the base station 110 may select cells of different RATs to add as SCGs (e.g., in dual connectivity NSA mode), may determine the best beam pair for communicating with the UE (e.g., the best base station transmit beam and / or the best UE receive beam), may select a target cell for a switching procedure, and so on.

[0130] However, some measurement configurations may result in poor beam management. For example, a UE connected to a cell of a first RAT may be configured with a measurement configuration for an inter-RAT (IRAT) cell selection procedure. The IRAT cell selection procedure may be configured with a measurement event (e.g., a B1 measurement event) for reporting a measurement value of a second RAT to a base station of the first RAT. In some aspects, the UE may detect and measure a beam of a second RAT using a wide beam (e.g., a beam that has not been refined and / or a beam associated with a small beamforming gain). The UE may (e.g., using a wide beam) determine a channel condition value of a beam of the second RAT to determine whether the channel condition value of the beam of the second RAT satisfies or triggers a measurement event for reporting the measurement value of the second RAT to the base station of the first RAT. However, the wide beam may not provide sufficient beamforming gain for the channel condition value of the beam of the second RAT to satisfy or trigger a measurement event for reporting the measurement value of the second RAT to the base station of the first RAT. For example, a UE with poor antenna coverage and / or a UE that is a client equipment (CPE), etc., may not be able to use a wide beam to achieve sufficient beamforming gain when measuring a beam of the second RAT to satisfy or trigger a measurement event for reporting the measurement value of the second RAT to the base station of the first RAT. For example, near the cell edge of a cell of the second RAT, the UE may use a wide beam to determine a poor (or lower) channel condition value for the beam of the second RAT compared to the case where the UE uses a narrow beam to measure the beam of the second RAT. As a result, the UE may not report the channel condition value of the beam of the second RAT to the base station of the first RAT.

[0131] Thus, the base station of the first RAT may not add the cell of the second RAT as an SCG, even though measurements of the beam of the second RAT by the UE using a more refined or narrower beam would have resulted in a channel condition value that would have satisfied or triggered a measurement event for reporting the measurement value of the second RAT to the base station of the first RAT. Thus, the IRAT measurement configuration may result in poor beam management because not adding the cell of the second RAT as an SCG (e.g., because the channel condition value of the beam of the second RAT is not reported as a value determined by the UE using a wide beam) may degrade network performance (e.g., throughput may be reduced compared to a case where the cell of the second RAT is added as an SCG, etc.).

[0132] In addition, the UE may be configured with a layer 1 (L1) reference signal received power (L1-RSRP) measurement configuration. The L1-RSRP measurement configuration may configure the UE to measure the RSRP values ​​of one or more SSBs transmitted by the base station. The base station 110 may receive a report indicating the RSRP values ​​of the one or more SSBs and select the SSB associated with the highest RSRP value to become the serving SSB. However, in some scenarios, two or more SSBs may have similar RSRP values. The RSRP values ​​of two or more SSBs may fluctuate (e.g., due to fading, measurement errors, etc.) so that the SSB with the best RSRP value between two or more SSBs changes frequently. As a result, the base station 110 may frequently trigger SSB switching (e.g., switching the serving SSB from one SSB to another SSB). Due to frequent switching between beams, frequent SSB switching may result in poor network performance. Additionally, frequent SSB switching may increase the signaling overhead associated with the UE reporting the new best SSB and the base station 110 signaling the SSB switching to the UE.

[0133] Some techniques and apparatus described herein implement improved beam management. For example, a UE may be enabled to measure a beam according to a measurement configuration to determine a channel state value for the beam. The UE may modify the channel state value and transmit a measurement report indicating the modified channel state value to a base station. As a result, the base station may be enabled to perform improved beam management based on the measurement report indicating the modified channel state value. The improved beam management results in improved network performance (e.g., due to increased throughput achieved through beam management, due to a reduction in beam switching, etc.). Additionally, the improved beam management reduces the signaling overhead that would otherwise exist when transmitting a measurement report indicating an original (e.g., unmodified) channel state value.

[0134] Figure 6 6 is a diagram illustrating an example 600 associated with improved beam management according to the present disclosure. Figure 6As shown in , UE 120 can establish a communication connection with a first cell (e.g., a primary cell (PCell)) associated with a first base station 110 in a first cell group (e.g., MCG). In some aspects, a second cell associated with a second base station 110 can be a candidate cell for dual connectivity with the first cell (e.g., can be a candidate for a primary secondary cell (PSCell) to be used as a second cell group (e.g., SCG)). In some aspects, the first cell can be associated with a first RAT (e.g., LTE RAT, 4G RAT, etc.). The second cell can be associated with a first RAT or a second RAT (e.g., NRRAT, 5G RAT, etc.). In some aspects, there may be multiple second cells, which can be candidates for dual connectivity with the first cell in a manner similar to that described herein.

[0135] As indicated by reference numeral 610, the UE 120 may receive a measurement configuration from a first base station 110 of a first cell. The measurement configuration may indicate a measurement event for reporting a measurement value of a cell associated with a second RAT to the first base station 110 (e.g., associated with a first RAT). The measurement event may be a B1 measurement event (e.g., for reporting an IRAT neighbor cell). The measurement event may be associated with an IRAT cell selection procedure. For example, the measurement event may be associated with a cell selection procedure for selecting a cell associated with a second RAT for dual connectivity with a first cell.

[0136] The measurement event may indicate a reporting threshold for reporting a measurement value associated with a cell of the second RAT. In some aspects, the reporting threshold may indicate a channel condition value (e.g., an RSRP value, a signal-to-noise ratio (SNR) value, etc.) that serves as a threshold channel condition value for reporting a channel condition value associated with a cell of the second RAT. That is, if the UE 120 measures a beam associated with the second RAT and determines that the channel condition value of the beam associated with the second RAT satisfies the reporting threshold, the UE 120 may report the channel condition value of the beam associated with the second RAT to the first base station 110 associated with the first RAT.

[0137] As indicated by reference numeral 620, UE 120 may measure beams of a second cell according to the measurement configuration received from the first cell. In some aspects, UE 120 may measure one or more beams of the second cell. In some aspects, UE 120 may measure beams from one or more other cells associated with the second RAT. UE 120 may determine a channel condition value (e.g., an RSRP value, an SNR value, etc.) for the beams of the second cell. The measurement of the beams of the second cell may be a layer 3 (L3) measurement.

[0138] In some aspects, the UE 120 may use a wide beam to measure the beam of the second cell. A wide beam may be a beam having large coverage or beamwidth relative to a refined beam having lower coverage or beamwidth (e.g., a wide beam may cover 90 degrees, etc.). In some aspects, the wide beam may be an unrefined beam. The UE 120 may use a wide beam to measure the beam of the second cell to reduce the amount of time associated with measuring the beam of the second RAT (e.g., using a refined or narrow beam to measure the beam of the second cell may require a beam sweeping procedure, which may increase the amount of time associated with measuring the beam of the second RAT).

[0139] As indicated by reference numeral 630, the UE 120 may determine or detect a modification trigger event based at least in part on a measurement of a beam of the second cell. The modification trigger event may indicate that the UE 120 should modify the channel condition value of the beam of the second cell. In some aspects, the modification trigger event may be based at least in part on a measurement event indicated by the measurement configuration. For example, the modification trigger event may be based at least in part on a reporting threshold for reporting the channel condition value of the second RAT (e.g., configured in the measurement configuration received from the first base station 110 of the first cell). The modification trigger event may be based at least in part on the difference between the channel condition value of the beam of the second cell and the reporting threshold for reporting the channel condition value of the second RAT satisfying a threshold. In some aspects, the threshold may be based at least in part on a beamforming gain value determined by the UE 120. In some aspects, the threshold may be 6 dB, etc. (e.g., if the channel condition value of the beam of the second cell is within 6 dB of the reporting threshold for reporting the channel condition value of the second RAT, the UE 120 may determine that the modification trigger event has been detected).

[0140] In some aspects, the modification trigger event may indicate that the beam of the second cell is near a cell edge of the second cell based at least in part on a channel condition value of the beam of the second cell. For example, if the channel condition value of the beam of the second cell satisfies a cell edge threshold, the UE 120 may determine that the modification trigger event has been detected. In some aspects, if the channel condition value of the beam of the second cell is less than a cell edge threshold, the UE 120 may determine that the modification trigger event has been detected. The cell edge threshold may be preconfigured or stored in the UE 120 or indicated by the first base station 110 of the first cell. In some aspects, the cell edge threshold may be -95 dBm, etc.

[0141] As indicated by reference numeral 640, UE 120 may modify the channel condition value of the beam of the second cell. UE 120 may modify the channel condition value of the beam of the second cell based at least in part on determining the modification triggering event. In some aspects, UE 120 may modify the channel condition value of the beam of the second cell by a beamforming gain value. The beamforming gain value may be a nominal value to indicate a beamforming gain that may be achieved by beamforming or refining a wide beam used by UE 120 to measure the beam of the second cell and determine the channel condition value of the beam of the second cell, as described above.

[0142] The beamforming gain value may be based at least in part on an antenna module associated with a wide beam used to determine a channel condition value for a beam of the second cell, a wide beam used to determine a channel condition value for a beam of the second cell, and / or determining an availability of a beam level of an antenna module associated with a wide beam used to determine a channel condition value for a beam of the second cell, etc. The beamforming gain value may be based at least in part on one or more beam characteristics (e.g., an angle of the beam of the second cell, a codebook associated with the wide beam, phase information associated with the wide beam, and / or amplitude information associated with the wide beam), a derivation of a beamforming gain value, and / or an estimation of a beamforming gain value.

[0143] For example, the nominal beamforming gain value may be applied to all wide beams associated with an antenna module of UE 120 (e.g., the nominal beamforming gain value may be antenna module specific). The nominal beamforming gain value may be an average beamforming gain value that may be expected when performing beamforming or beam refinement using the antenna module. In some aspects, the nominal beamforming gain value may be based at least in part on a wide beam used to measure a beam of a second cell (e.g., the nominal beamforming gain value may be antenna module specific). The nominal beamforming gain value may be an average beamforming gain value that may be expected when performing beamforming or beam refinement of a wide beam.

[0144] In some aspects, the nominal beamforming gain value may be based at least in part on the beam level. For example, a codebook associated with a wide beam (or associated with an antenna module associated with a wide beam) may indicate beams associated with multiple levels. The level of a beam (e.g., a beam level) may be associated with a specific beam width and a specific beam gain. As the level changes, the beam width and beam gain may change. As an example, when the beam level increases, the beam width may decrease and the beam gain may increase. The codebook may include multiple levels, such as two levels, three levels, or different numbers of levels. The use of beam levels may improve the efficiency of the beam refinement operation of UE 120. For example, the use of three beam levels may provide a desired balance between beam width and beamforming gain, because a wide beam (level), an intermediate beam (level), and a narrow beam (level) may be formed using a three-level codebook approach. In another example, multiple beam levels may include a wide beam level and one or more refined beam levels. The wide beam level may be associated with one or more beams having a different direction (e.g., a different spatial direction) of a beamwidth that is wider than a beam having the one or more refined beam levels. In other words, the width of the beam having the one or more refined beam levels may be narrower than the beamwidth associated with the wide beam level.

[0145] In some aspects, the codebook may indicate a parent-child relationship of two or more beams. The parent beam may be a beam associated with a lower level (e.g., a larger beam width and a lower beam gain) and the child beam may be a beam associated with a higher level. The UE 120 may move from the parent beam to the corresponding child beam as part of a beam refinement procedure. For example, the UE 120 may perform measurements on a child beam corresponding to a parent beam or on a parent beam corresponding to a child beam as part of a beam refinement procedure.

[0146] In some aspects, the UE 120 may determine the highest available level associated with the widest beam width to determine the beamforming gain. The available beam level may be a beam level in which all beams included in the level are available. The availability of the beams included in the beam level may be based at least in part on an operating condition of the UE 120 (e.g., a thermal condition, a power usage condition, a battery condition, a maximum permitted exposure (MPE) condition, a dynamic selection of the number of antennas from a set of antenna modules supported by the UE 120, a preferred subarray type supported by the UE 120, a use case (e.g., a data rate use case and / or a latency use case), or another type of operating condition). For example, the UE 120 may determine that one or more beams included in the level are unavailable or disqualified based at least in part on the operating condition. As a result, the UE 120 may not use the beamforming gain value associated with the level when modifying the channel condition value of the beam of the second cell.

[0147] In some aspects, UE 120 may determine available levels starting from a highest beam level (e.g., a beam level associated with a minimum beam width and / or a maximum beamforming gain value). If UE 120 determines that the highest level is available, UE 120 may determine that the beamforming gain value is the beamforming gain value associated with the highest level. If UE 120 determines that the highest level is not available, UE 120 may determine whether a second highest beam level is available. UE 120 may repeat the process until UE 120 determines the highest available beam level. UE 120 may determine that the beamforming gain value is the beamforming gain value associated with the highest available beam level.

[0148] UE 120 may modify the channel condition value of the beam of the second cell by the beamforming gain value. For example, UE 120 may add the beamforming gain value to the channel condition value of the beam of the second cell. As a result, UE 120 may determine whether to use the modified channel condition value to report the channel condition value of the beam of the second cell. The modified channel condition value may enable UE 120 to use a more accurate channel condition value of the beam of the second cell (e.g., the channel condition value of the beam of the second cell after performing a beam refinement procedure) while also saving resources (e.g., time resources and / or power resources) by measuring the beam of the second cell using a wide beam (e.g., rather than one or more narrow beams or one or more refined beams).

[0149] As indicated by reference numeral 650, UE 120 may transmit a measurement report indicating a modified channel condition value for a beam of a second cell to first base station 110 of the first cell. For example, UE 120 may determine that the modified channel condition value for the beam of the second cell satisfies a reporting threshold for reporting channel condition values ​​for a second RAT. UE 120 may transmit a measurement report indicating a modified channel condition value for the beam of the second cell based at least in part on determining that the modified channel condition value for the beam of the second cell satisfies the reporting threshold for reporting channel condition values ​​for the second RAT (e.g., if the modified channel condition value for the beam of the second cell does not satisfy the reporting threshold for reporting channel condition values ​​for the second RAT, UE 120 may not transmit the measurement report).

[0150] The first base station 110 of the first cell may receive a measurement report indicating a modified channel condition value of a beam of the second cell. The first base station 110 may transmit to the UE 120 an indication that the second cell is to be added as a PSCell for dual connectivity with the first cell. The UE 120 may perform a beam refinement procedure in association with adding the second cell as a PSCell. As a result, when the second cell is added as a PSCell, the UE 120 may achieve a beamforming gain value by performing a beam refinement procedure. Thus, after adding the second cell as a PSCell, the UE 120 may operate in a dual connectivity mode with the first cell as a PCell of the MCG and the second cell as a PSCell of the SCG. The dual connectivity mode may improve network performance and increase throughput of the UE 120.

[0151] As a result, UE 120 improves beam management by modifying the channel condition value of the beam of the second cell by the expected beamforming gain value. The modified channel condition value of the beam of the second cell enables UE 120 to report the second cell to the first cell while also maintaining resources saved by measuring the beam of the second cell using a wide beam. Reporting the modified channel condition value improves beam management by enabling the first cell to add the second cell as a PSCell of the SCG, thereby improving network performance associated with UE 120 operating in dual connectivity mode.

[0152] As indicated above, Figure 6 are provided as examples. Other examples may differ from those described herein. Figure 6 Examples described.

[0153] Figure 7 is a diagram illustrating an example 700 associated with improved beam management according to the present disclosure. Figure 7As shown in FIG. 1 , base station 110 and UE 120 may communicate with each other in a wireless network (eg, wireless network 100 ).

[0154] As indicated by reference numeral 710, base station 110 may transmit a measurement configuration to UE 120. The measurement configuration may indicate conditions for reporting channel condition values ​​(e.g., RSRP values, SNR values, etc.) of different beams to base station 110. Base station 110 may use the reported channel condition values ​​for beam management.

[0155] The measurement configuration may indicate a measurement event associated with a beam switching procedure. In some aspects, the measurement event may be associated with an L1-RSRP measurement report. For example, the measurement event may indicate that UE 120 is to measure one or more SSBs transmitted by base station 110 and report one or more highest RSRP values ​​of the one or more SSBs to base station 110. Base station 110 may use the L1-RSRP measurement report to select the best SSB to become the serving SSB for UE 120.

[0156] As indicated by reference numeral 720, UE 120 may measure one or more SSBs transmitted by base station 110 according to the measurement configuration. The one or more SSBs may be transmitted on one or more transmit beams of base station 110. UE 120 may measure the one or more SSBs using a receive beam of UE 120. UE 120 may determine channel condition values ​​for the one or more SSBs based at least in part on the measurement of the one or more SSBs. The measurement of the one or more SSBs may be an L1 measurement.

[0157] As indicated by reference numeral 730, UE 120 may determine a modification triggering event. The modification triggering event may be based at least in part on one or more measurements of the one or more SSBs. The modification triggering event may be an event indicating that UE 120 should modify the RSRP value of the serving SSB when transmitting the L1-RSRP measurement report. In some aspects, the modification triggering event may be based at least in part on the channel condition value of the serving SSB. For example, based at least in part on the previous L1-RSRP measurement report, base station 110 may configure or indicate the serving SSB for UE 120 (e.g., using media access control (MAC) control element (MAC-CE) signaling). The serving SSB may be the SSB associated with the highest RSRP value in the previous L1-RSRP measurement report.

[0158] UE 120 may determine the modification trigger event based at least in part on determining that the serving SSB does not have the highest RSRP value among the one or more SSBs. For example, UE 120 may determine that another SSB has a higher RSRP value than the RSRP value of the serving SSB. UE 120 may determine the modification trigger event based at least in part on determining that a difference between the highest RSRP value (e.g., of another SSB) and the RSRP value of the serving SSB satisfies an RSRP threshold. For example, UE 120 may determine that the RSRP value of the serving SSB is within a threshold of the highest RSRP.

[0159] In some aspects, UE 120 may determine the modification trigger event based at least in part on the amount of time since the last SSB switch (e.g., the amount of time since base station 110 indicated a switch from a previous serving SSB to a current serving SSB). UE 120 may determine the modification trigger event based at least in part on determining that the amount of time since the last SSB switch satisfies a time threshold. The time threshold may be 1 second, 2 seconds, and / or 4 seconds, etc. In some aspects, if UE 120 determines that the amount of time since the last SSB switch does not satisfy the time threshold (e.g., is greater than or equal to the time threshold), UE 120 may determine that the modification trigger event has not been met (e.g., even if the difference between the highest RSRP value and the RSRP value of the serving SSB satisfies the RSRP threshold).

[0160] In some aspects, the UE 120 may determine the modification triggering event based at least in part on the channel condition value of the serving SSB. For example, if the channel condition value of the serving SSB is bad, the UE 120 may not determine that the modification triggering event is detected or satisfied so that the channel condition value of the serving SSB is not modified (e.g., so that the base station 110 switches from the serving SSB with the bad channel condition value). In some aspects, the UE 120 may determine or detect the modification triggering event based at least in part on determining that the RSRP value of the serving SSB satisfies the serving RSRP threshold. In some aspects, the UE 120 may determine or detect the modification triggering event based at least in part on determining that the SNR of the serving SSB satisfies the serving SNR threshold. For example, if the RSRP value of the serving SSB does not satisfy the serving RSRP threshold and / or the SNR value of the serving SSB does not satisfy the serving SNR threshold, the UE 120 may determine that the modification triggering event has not been satisfied (e.g., even if the difference between the highest RSRP value and the RSRP value of the serving SSB satisfies the RSRP threshold and / or the amount of time since the last SSB switch satisfies the time threshold).

[0161] In some aspects, UE 120 may determine or detect the modification triggering event based at least in part on determining that a difference between a highest RSRP value and an RSRP value of a serving SSB satisfies an RSRP threshold, determining that an amount of time since a last SSB switch satisfies a time threshold, and / or determining that an RSRP value of a serving SSB satisfies a serving RSRP threshold (and / or an SNR value of a serving SSB satisfies a serving SNR threshold). In some aspects, the thresholds (e.g., RSRP thresholds, time thresholds, serving RSRP thresholds, serving SNR thresholds, etc.) may be preconfigured or stored by UE 120. In some aspects, the thresholds may be indicated or configured by base station 110.

[0162] As indicated by reference numeral 740, UE 120 may modify the channel condition value of the serving SSB. For example, UE 120 may modify the RSRP value (e.g., the measured RSRP value) of the serving SSB. In some aspects, UE 120 may modify the channel condition value of the serving SSB based at least in part on determining the modification triggering event. UE 120 may modify the RSRP value of the serving SSB by an RSRP modification value. The RSRP modification value may be based at least in part on a value associated with an RSRP threshold. For example, if the RSRP threshold indicates that the RSRP value of the serving SSB must be within 1 dB of the highest RSRP, the RSRP modification value may be 1 dB or greater. In this way, the RSRP value of the serving SSB may be modified to be the highest RSRP value.

[0163] The modification of the RSRP value of the serving SSB may introduce hysteresis into the reporting of the L1-RSRP measurement report. For example, the modification of the RSRP value of the serving SSB may ensure that, within a limited time period (e.g., based at least in part on a time threshold), the base station 110 does not switch the serving SSB due to slight fluctuations in the RSRP value of the one or more SSBs.

[0164] As indicated by reference numeral 750, UE 120 may transmit an L1-RSRP measurement report indicating a modified channel condition value (e.g., a modified RSRP value) of the serving SSB to base station 110. Base station 110 may receive the L1-RSRP measurement report and determine that the modified RSRP of the serving SSB is the highest RSRP value. As a result, base station 110 may not switch the serving SSB to another SSB even if the other SSB has a higher RSRP, as measured by UE 120.

[0165] As a result, frequent switching between SSBs as serving SSBs due to slight fluctuations in the RSRP values ​​of the SSBs can be avoided by transmitting an L1-RSRP measurement report indicating a modified RSRP value of the serving SSB. Transmitting an L1-RSRP measurement report indicating a modified RSRP value of the serving SSB improves beam management by improving network performance because the UE 120 and the base station 110 can reduce the number of beam switches of different SSBs. Additionally, transmitting an L1-RSRP measurement report indicating a modified RSRP value of the serving SSB improves beam management by reducing signaling overhead associated with frequent switching between SSBs as serving SSBs.
