[0003] DISCLOSURE
[0004] Aspects of the present disclosure generally relate to wireless communication, and to techniques and apparatuses for transmitting and receiving beam-dependent system information.
[0005] BACKGROUND
[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting 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 (3 GPP).
[0007] A wireless network can include one or more base stations that support communication for one or more user equipment (UEs). A UE can communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to
[0008] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is an enhancement set to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink, and CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to grow.

[0040] Detailed description
[0041] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice.

It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims.
[0042] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0043] While the aspects herein may be described using terms commonly associated with 5G or New Radio (NR) Radio Access Technology (RAT), the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).
[0044] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include a 5G (e.g., NR) network and / or a 4G (e.g., LTE) network, etc. Wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. Base station 110 is the entity that communicates with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit / receive point (TRP). Each base station 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of base station 110 and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.
[0045] Base station 110 provides communication coverage to macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UE 120 with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UE 120 with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UE 120 associated with that femtocell (e.g., UE 120 in a closed subscriber group (CSG)). Base station 110 for macrocells may be referred to as a macro base station. Base station 110 for picocells may be referred to as a pico base station. Base station 110 for femtocells may be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS 110a can be a macro base station for macro cell 102a, BS 110b can be a pico base station for pico cell 102b, and BS 110c can be a femto base station (BS) for femtocell 102c. A base station may support one or more (e.g., three) cells.
[0046] In some examples, the cell may not necessarily be stationary, and the geographical area of the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base stations 110 may interconnect with each other and / or interconnect to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces (such as direct physical connections or virtual networks).
[0047] Wireless network 100 may include one or more relay stations. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., base station 110 or UE 120) and transmitting those data transmissions to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 capable of relaying transmissions for other UE 120s. Figure 1 In the example shown, BS 110d (e.g., a relay base station) can communicate with BS 110a (e.g., a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. The base station 110 for relay communication may be referred to as a relay station, relay base station, relay, etc.
[0048] Wireless network 100 can be a heterogeneous network comprising different types of base stations 110 (such as macro base stations, pico base stations, femto base stations, or relay base stations, etc.). These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro base stations may have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts).
[0049] Network controller 130 can be coupled to or communicate with a group of base stations 110 and can provide coordination and control over these base stations 110. Network controller 130 can communicate with base stations 110 via backhaul communication links. Base stations 110 can communicate with each other directly or indirectly via wireless or wired backhaul communication links.
[0050] Each UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), an in-vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via a wireless medium.
[0051] Some UEs 120 may be considered Machine-Type Communication (MTC) UEs, or evolved or enhanced Machine-Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered client equipment. UE 120 may be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0052] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.
[0053] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, 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), vehicle-to-infrastructure (V2I), or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.
[0054] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., according to frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is generally (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes arise regarding FR2; although different from the Extremely High Frequency (EHF) band (30GHz–300GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is generally (interchangeably) referred to as “millimeter wave” or “mmW” in various documents and articles.
[0055] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands of these IF bands as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 into the IF band. Additionally, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating frequency bands have been designated as the frequency range designations FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.
[0056] Considering the examples above, unless otherwise stated, it should be understood that, as used herein, the terms "sub-6GHz," etc., can broadly refer to frequencies less than 6GHz, within FR1, or that may include intermediate frequency band frequencies. Furthermore, unless otherwise stated, it should be understood that, as used herein, the terms "millimeter wave," etc., can broadly refer to frequencies that may include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is conceivable that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0057] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.
[0058] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to this disclosure. The base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).
[0059] At base station 110, transmit processor 220 can receive data from data source 212 intended for UE 120 (or a group of UEs 120). Transmit processor 220 can select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Base station 110 can process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS(s) selected for UE 120 and can provide data symbols to UE 120. Transmit processor 220 can process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or higher-layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 can generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modulators) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a downlink signal. Modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).
[0060] At UE 120, an array of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110 and can provide a set of received signals (e.g., R received signals) to an array of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on these received symbols where applicable, and can provide detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.
[0061] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in the core network. Network controller 130 may communicate with base station 110 via communication unit 294.
[0062] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more antenna element assemblies, and / or one or more antenna arrays, etc., or may be included therein. Antenna panels, antenna groups, antenna element assemblies, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), coplanar antenna element assemblies, non-coplanar antenna element assemblies, and / or coupled to one or more transmit and / or receive components (such as...) Figure 2 One or more antenna elements (one or more components).
[0063] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). Transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from transmit processor 264 may be pre-encoded by TX MIMO processor 266 where applicable, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, modem 254 of UE 120 may include modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modems 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., references). Figures 7-14 ).
[0064] At base station 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antennas 234, modems 232, MIMO detectors 236, receiver processors 238, transmitter processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., references). Figures 7-14 ).
[0065] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2Any other component may perform one or more techniques associated with transmitting and receiving beam-related system information, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component may execute or direct, for example Figure 9 The process 900 Figure 10 Process 1000 Figure 11 Process 1100 Figure 12 The operation of process 1200 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for base station 110 and UE 120, respectively. In some examples, 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, when executed by one or more processors of base station 110 and / or UE 120 (e.g., direct execution, or execution after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or base station 110 may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 9 The process 900 Figure 10 Process 1000 Figure 11 Process 1100 Figure 12 The operation of process 1200 and / or other processes described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions, and / or interpret instructions, etc.
[0066] In some respects, UEs (e.g., UE 120 and / or Figure 13 The apparatus 1300 may include: for receiving signals from a base station (e.g., base station 110 and / or...) Figure 14The apparatus 1400 includes means for receiving a first synchronization signal associated with a first beam; means for receiving scheduling information from the base station based at least in part on the first synchronization signal; and / or means for receiving first system information associated with the first beam from the base station based at least in part on the scheduling information, wherein the first system information is different from second system information associated with a second beam. Means for the UE to perform the operations described herein may include, for example, one or more of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282. Additionally or alternatively, the UE may include means for receiving first system information associated with the first beam from the base station based at least in part on scheduling information, wherein the first system information is received using one or more first receive parameters, which are different from one or more second receive parameters used for second system information associated with a second beam.
[0067] In some aspects, base stations (e.g., base station 110 and / or Figure 14 The device 1400 may include: for sending signals to the UE (e.g., UE 120 and / or Figure 13 The apparatus 1300 includes means for transmitting a first synchronization signal associated with a first beam; means for transmitting scheduling information to the UE based at least in part on the first synchronization signal; and / or means for transmitting first system information associated with the first beam to the UE based at least in part on the scheduling information, wherein the first system information is different from second system information associated with a second beam. The means for the base station to perform the operations described herein may include, for example, one or more of a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246. Additionally or alternatively, the base station may include means for transmitting first system information associated with the first beam to the UE based at least in part on scheduling information, wherein the first system information is transmitted using one or more first receive parameters, which are different from one or more second receive parameters used for second system information associated with a second beam.
[0068] although Figure 2The boxes in the diagram are interpreted as different components, but the functions described above with respect to these boxes can be implemented by a single hardware component, software component, or combination of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of controller / processor 280.
[0069] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.
[0070] Figure 3 This is a diagram illustrating an example beamforming architecture 300 supporting beamforming for mmW communication according to this disclosure. In some aspects, architecture 300 can implement various aspects of wireless network 100. In some aspects, 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.
[0071] Broadly speaking, Figure 3 This is a diagram illustrating example hardware components of a wireless communication device according to certain aspects of this disclosure. The illustrated components may include those that can be used for antenna element selection and / or beamforming for wireless signal transmission. Numerous architectures exist for antenna element selection and phase shifting; only one example 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. In some examples, the modem 302 may be a combination of... Figure 2 One or more of the described modem 232 or modem 254.
[0072] Transmission lines or other waveguides, wires, and / or traces are shown as connecting various components to illustrate how the signals to be transmitted can travel between the components. Reference numerals 322, 324, 326, and 328 indicate areas in 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 controller / processor 334. In some aspects, the processor / processor 334 corresponds to the above combination. Figure 2 The described base station's processor / processor 240 and / or more combined Figure 2 The controller / processor 280 of the described UE.
[0073] 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 cross-polarized with a second sub-element, which can be used independently to transmit cross-polarized signals. 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 transmitted separately by the antenna elements 320 to interact or interfere (e.g., to form a desired beam). For example, given a desired range of wavelengths or frequencies, the spacing may provide a quarter wavelength, half a wavelength, or other fraction of the wavelength between adjacent antenna elements 320 to allow interaction or interference of signals transmitted by individual antenna elements 320 within that desired range.
[0074] Modem 302 processes and generates digital baseband signals and can also control the operation of DAC 304, first and second mixers 306 and 308, splitter 310, first amplifier 312, phase shifter 314, and / or second amplifier 316 to transmit signals via one or more antennas in antenna element 320. Modem 302 can process signals and control operations according to communication standards, such as wireless standards discussed herein. DAC 304 can convert digital baseband signals received from modem 302 (and to be transmitted) into analog baseband signals. First mixer 306 uses local oscillator A 330 to upconvert the analog baseband signal to an analog IF signal within the IF. For example, first mixer 306 can mix the signal with an oscillation signal generated by local oscillator A 330 to “shift” the baseband analog signal to the IF. In some cases, some processing or filtering (not shown) can be performed at the IF. The second mixer 308 uses a local oscillator B 332 to upconvert 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 the local oscillator B 332 to "move" the IF analog signal to the RF frequency, or the frequency at which the signal will be transmitted or received. The modem 302 and / or the controller / processor 334 can adjust the frequencies of the local oscillator A 330 and / or the local oscillator B 332 such that the desired IF and / or RF frequencies are generated and used to facilitate the processing and transmission of signals within the desired bandwidth.
[0075] In the illustrated architecture 300, the signal up-converted by the second mixer 308 is split or duplicated into multiple signals by the splitter 310. The splitter 310 in architecture 300 splits the RF signal into multiple identical or nearly identical RF signals. In other examples, any type of signal (including baseband digital signals, baseband analog signals, or IF analog signals) can be split. Each of these signals may correspond to an antenna element 320, and the signal travels through or is processed by amplifiers 312 and 316, phase shifter 314, and / or other elements corresponding to the respective antenna element 320 for transmission to the corresponding antenna element 320 in the antenna array 318. In one example, the splitter 310 may be an active splitter connected to a power supply and providing some gain such 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, splitter 310 is a passive splitter not connected to a power source, and the RF signal leaving splitter 310 may be at a lower power level than the RF signal entering splitter 310.
[0076] 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 and 316 are illustrated with dashed lines because in some respects, one or both may not be necessary. In some respects, both first amplifier 312 and second amplifier 316 are present. In some respects, neither first amplifier 312 nor second amplifier 316 is present. In some respects, one of the two amplifiers 312 and 316 is present, but the other is absent. As an example, if splitter 310 is an active splitter, first amplifier 312 may not be used. As a further example, if phase shifter 314 is an active phase shifter that provides gain, second amplifier 316 may not be used.
[0077] Amplifiers 312 and 316 can provide a desired level of positive or negative gain. Positive gain (positive dB) can be used to increase the amplitude of the signal radiated by a particular antenna element 320. Negative gain (negative dB) can be used to decrease the amplitude of the signal radiated by a particular antenna element and / or suppress its radiation. Each of amplifiers 312 and 316 can be independently controlled (e.g., by modem 302 or controller / processor 334) to provide independent control of the gain for each antenna element 320. For example, modem 302 and / or controller / processor 334 may have at least one control line connected to each of splitter 310, first amplifier 312, phase shifter 314, and / or second amplifier 316, which can be used to configure the gain to provide the desired amount of gain for each component and therefore each antenna element 320.
[0078] Phase shifter 314 can provide a configurable phase shift or phase offset to the corresponding RF signal to be transmitted. Phase shifter 314 can be a passive phase shifter that is not directly connected to a power supply. Passive phase shifters may introduce some insertion loss. Second amplifier 316 can boost the signal to compensate for the insertion loss. Phase shifter 314 can also be an active phase shifter connected to a power supply, such that the active phase shifter provides a certain amount of gain or prevents insertion loss. The settings of each phase shifter 314 are independent, meaning that each phase shifter can be independently configured to provide the desired amount of phase shift, the same amount of phase shift, or some other configuration. Modem 302 and / or controller / processor 334 may have at least one control line connected to each phase shifter 314, and this at least one control line can be used to configure the phase shifter 314 to provide the desired amount of phase shift or phase offset between the respective antenna elements 320.
[0079] 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 amplifiers 356 may be connected to the same antenna array 318 (e.g., for time division duplex (TDD) operation). The first amplifiers 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 shifters 354 may be active or passive phase shifters. The settings of each phase shifter 354 are independent, meaning that each phase shifter can be independently configured to provide the desired amount of phase shift, the same amount of phase shift, or some other configuration. The modem 302 and / or controller / processor 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 amount of phase shift or phase offset between each antenna element 320 to achieve reception via one or more Rx beams.
[0080] The output of phase shifter 354 can be input to one or more second amplifiers 352 for signal amplification of the phase-shifted received RF signal. Second amplifiers 352 can be individually configured to provide a configured gain amount. Second amplifiers 352 can be individually configured to provide a gain amount to ensure that signals input to combiner 350 have the same amplitude. Amplifiers 352 and / or 356 are illustrated with dashed lines because they may not be necessary in some respects. In some respects, both amplifiers 352 and 356 are present. In other respects, neither amplifiers 352 nor 356 are present. In still other respects, one of amplifiers 352 and 356 is present, but the other is absent.
[0081] In the described architecture 300, the signal output from phase shifter 354 (via amplifier 352 when present) is combined in combiner 350. Combiner 350 in architecture 300 combines this RF signal into a single signal. Combiner 350 can be a passive combiner (e.g., not connected to a power supply), which may result in some insertion loss. Combiner 350 can be an active combiner (e.g., connected to a power supply), which may result in some signal gain. When combiner 350 is an active combiner, it can provide different (e.g., configurable) amounts of gain for each input signal so that the input signals have the same amplitude when combined. When combiner 350 is an active combiner, combiner 350 may not require a second amplifier 352 because the active combiner can provide signal amplification.
[0082] The output of combiner 350 is input to mixers 348 and 346. Mixers 348 and 346 typically use inputs from local oscillators 372 and 370, respectively, to down-convert the received RF signal to produce an intermediate or baseband signal carrying encoded and modulated information. The outputs of mixers 348 and 346 are input to an analog-to-digital converter (ADC) 344 for conversion to an analog signal. The analog signal output from ADC 344 is input to modem 302 for baseband processing, such as decoding, deinterleaving, or similar operations.
[0083] Architecture 300 is shown by way of example only to illustrate an architecture for transmitting and / or receiving signals. In some cases, architecture 300 and / or each part of architecture 300 may be repeated multiple times within the architecture to accommodate or provide any number of RF chains, antenna elements, and / or antenna panels. Furthermore, numerous alternative 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 having its own corresponding amplifier, phase shifter, splitter, mixer, DAC, ADC, and / or modem, one or more of these. 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.
[0084] Furthermore, mixers, splitters, amplifiers, phase shifters, and other components can be located in different signal type regions within different implementation architectures (e.g., indicated by different reference numerals in figures 322, 324, 326, and 328). 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, amplifiers 312 and 316, or phase shifter 314 can be located between DAC 304 and the first mixer 306 or between the first mixer 306 and the second mixer 308. In one example, the functionality of one or more components can be combined into a single component. For example, phase shifter 314 can perform amplification to include or replace the first amplifier 312 and / or the second amplifier 316. As another example, phase shifting can be implemented by the second mixer 308 to eliminate the need for a 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 different phase shifts) to each IF-to-RF mixer.
[0085] Modem 302 and / or controller / processor 334 can control one or more of other components 304 to 372 to select one or more antenna elements 320 and / or form a beam for transmitting one or more signals. For example, antenna elements 320 can be individually selected for signal (or individual signals) transmission or deselected by controlling the amplitude of one or more corresponding amplifiers (such as first amplifier 312 and / or second amplifier 316). Beamforming involves generating a beam using multiple signals on different antenna elements, wherein one or more or all of these signals are phase-shifted relative to each other. The formed beam can carry physical or higher-level reference signals or information. As each of these multiple signals radiates from the corresponding antenna element 320, the radiated signals interact, interfere (constructive interference and destructive interference), and amplify each other to form the resulting beam. Shape (such as the amplitude, width, and / or presence of sidelobes) and orientation (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 and 316 relative to each other. The controller / processor 334 may be partially or wholly located within one or more other components of the architecture 300. For example, in some aspects, the controller / processor 334 may be located within the modem 302.
[0086] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.
[0087] Figure 4 This is a diagram illustrating example 400 of the search space for RMSI scheduling according to this disclosure. (See diagram for example 400 400 400 5 ... Figure 4 As shown, a base station (e.g., base station 110) can broadcast a synchronization signal block (SSB) 405. SSB 405 may include a PSS and SSS centralized within the Physical Broadcast Channel (PBCH). Accordingly, as Figure 4 As shown, SSB 405 can also be referred to as SS / PBCH block 405.
[0088] One or more UEs (e.g., UE 120a and / or UE 120b) may receive SSB 405 to perform initial cell search, radio resource measurement (RRM), radio link monitoring (RLM), and / or beam identification. For example, in beam identification, UE 120a and UE 120b may use different SSBs broadcast by base station 110 to identify different beams used by base station 110 (e.g., as combined with...). Figure 3 (The land described was formed).
[0089] In some aspects, UE 120a and UE 120b can detect the PSS and / or SSS to determine the physical cell identifier associated with base station 110 and the timing associated with the PBCH. Accordingly, UE 120a and UE 120b can decode the PBCH to obtain the Master Information Block (MIB). The MIB may include frequency and timing information that allows UE 120a and UE 120b to connect to the cell including base station 110, as well as information for scheduling the reception of Residual Minimum System Information (RMSI) by UE 120a and UE 120b. For example, the MIB may include a pdcch-ConfigSIB1 data structure (e.g., as defined in 3GPP specifications and / or another standard) or another similar data structure defining a search space (e.g., in the Physical Downlink Control Channel (PDCCH)), where UE 120a and UE 120b can receive scheduling information for the RMSI. This search space can be referred to as the Type0-PDCCH Shared Search Space (CSS).
[0090] In some aspects, the MIB may include information for defining the configuration of a control resource set (CORESET) for monitoring physical resources (e.g., one or more frequencies, one or more time slots, etc.) used to monitor Type 0-PDCCH CSS. Accordingly, such as Figure 4 As shown, CORESET 410 may be referred to as Type0 PDCCH CORESET 410 (Type 0PDCCH CORESET 410). CORESET 410 may include components from the initial physical resource block (PRB) (e.g., Figure 4 Starting with PRB 415) Resource Block (RB). In some respects, the MIB can indicate the overlapping PRB 420 from SSB 405 and Type0-PDCCH CORESET 410 to the lowest PRB used for Type0-PDCCH CORESET 410 (e.g., Figure 4 The offset of PRB 415 in the MIB. Additionally, the MIB can indicate the offset k. SSB (For example, ssb-SubcarrierOffset (ssb-subcarrier offset) and / or another similar variable as defined in the 3GPP specification), the offset k SSB Indicates the number of frequency modulations of the lowest subcarrier from Type0-PDCCH CORESET 410 and SSB 405 so that UE 120a and UE 120b can determine the PRB grating used by base station 110 to transmit control information and data.
[0091] As indicated above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.
[0092] Figure 5A and 5B This explains separately the monitoring opportunities used for RMSI scheduling according to this disclosure (e.g., as in conjunction with...). Figure 4 The monitoring timing described in the Type0-PDCCH CSS) is used to multiplex synchronization signals (e.g., as combined with... Figure 4 Illustrations of examples 500 and 550 of the described SSB. One or more UEs (e.g., UE 120a and / or UE 120b) may receive (e.g., from base station 110) scheduling information (e.g., on the PDCCH) including a System Information Block (SIB) comprising the RMSI during monitoring. In example 500, the SSB is time-multiplexed with the Type 0-PDCCH CSS. In example 550, the SSB is frequency-multiplexed with the Type 0-PDCCH CSS.
[0093] like Figure 5A As shown, the Type0-PDCCH CSS can be defined within one or more radio frames in a set of radio frames 501 (e.g., each frame is 10 ms long). In some aspects, the Type0-PDCCH CSS can be configured for the first frame and every other frame thereafter (e.g., when the system frame number (SFN) mod 2 = 0). Alternatively, the Type0-PDCCH CSS can be configured for the second frame and every other frame thereafter (e.g., when SFN mod 2 = 1). Figure 5A As further shown, each frame may include multiple time slots 503 (e.g., 10 time slots per frame, 20 time slots per frame, etc.).
[0094] In some aspects, such as Figure 5A As shown, UE 120a and UE 120b can monitor two time slots 505 corresponding to the selected SSB to look for RMSI scheduling information. Figure 5A As further shown, these two time slots 505 can follow the offset O defined in the MIB (e.g., as combined with...). Figure 4 (As described). In Example 500, the offset O for FR1 can be selected from 0, 2, 5, or 7 ms. Although the description herein focuses on these values of offset O for FR1, the description similarly applies to other values of offset O. For example, as... Figure 5A As shown, the offset O for FR2 can be selected from 0, 2.5, 5, or 7.5 ms.
[0095] The selected SSB may have an associated index i. Accordingly, in some respects, UE 120a and UE 120b may determine the index used for monitoring timing associated with the selected SSB. For example, UE 120a and UE 120b may determine these indices at least in part based on expressions of a similar form:
[0096]
[0097] Where n0 represents the index of the first time slot of the two time slots, O represents the offset (e.g., as described above), μ represents the index based on the number of time slots per frame, i represents the index of the selected SSB, and M represents the step index defined in the MIB (e.g., as combined with...). Figure 4 (as described), and This indicates the number of time slots per frame. In some respects, the index of the second time slot in a two-slot configuration can correspond to n0+1.
[0098] As an alternative, and as Figure 5B As shown, Type0-PDCCH CSS can be defined in time slots (e.g., time slot n, time slot n+1, etc.). Figure 5B Within one or more symbols (as shown in Example 550). In Example 550, Type0-PDCCHCSS may include symbol 0 (in time slot n), symbol 1 (in time slot n), symbol 2 (in time slot n), symbol 3 (in time slot n), symbol 12 (in time slot n), symbol 13 (in time slot n), symbol 0 (in time slot n+1), or symbol 1 (in time slot n+1) for SSB indices 8k, 8k+1, 8k+2, 8k+3, 8k+4, 8k+5, 8k+6, and 8k+7, respectively, where k represents a natural number. As further shown in Example 550, when the SSB is transmitted in one or more of symbols 4-11 in the same time slot n, Type0-PDCCHCSS may include symbols 0, 1, 2, and / or 3 in time slot n. Similarly, when the SSB is transmitted in one or more of symbols 2-9 in the same time slot n+1, the Type0-PDCCH CSS may include symbols 0 and / or 1 in time slot n+1. Alternatively, when the SSB is transmitted in one or more symbols in the next time slot n+1, the Type0-PDCCH CSS may include symbols 12 and / or 13 in time slot n.
[0099] Although the description uses symbol 0 (in time slot n), symbol 1 (in time slot n), symbol 2 (in time slot n), symbol 3 (in time slot n), symbol 12 (in time slot n), symbol 13 (in time slot n), symbol 0 (in time slot n+1), or symbol 1 (in time slot n+1) for SSB indices 8k, 8k+1, 8k+2, 8k+3, 8k+4, 8k+5, 8k+6, and 8k+7 respectively, this description similarly applies to other symbols used for other SSB indices. For example, when an SSB is transmitted in symbol 0 and / or 1 in the same time slot n, the Type0-PDCCH CSS may include symbol 2 and / or 3 in time slot n. As another example, Type0-PDCCHCSS may include symbols 0, 1, 6, and / or 7 in time slot n for SSB indices 4k, 4k+1, 4k+2, and 4k+3, respectively, where k is a natural number. Accordingly, when the SSB is transmitted in one or more of symbols 2-5 in the same time slot n, Type0 PDCCH CSS may include symbols 0 and / or 1 in time slot n, and when the SSB is transmitted in one or more of symbols 8-11 in the same time slot n, Type0-PDCCH CSS may include symbols 6 and / or 7 in time slot n.
[0100] In some respects, UE 120a and UE 120b can measure different SSBs transmitted by base station 110 and use the SSB associated with the strongest signal strength to obtain RMSI. When base station 110 uses beamforming (e.g., as in combination with...), Figure 3 As described, the selection of SSB by UE 120a and UE 120b can also constitute the selection of the beam corresponding to that SSB.
[0101] As indicated above, Figure 5A and 5B This is provided as an example. Other examples may differ from the one provided. Figure 5A and Figure 5B The example described.
[0102] Figure 6 This is a diagram illustrating an example 600 of a search space for OSI scheduling according to this disclosure. One or more UEs (e.g., UE 120a and / or UE 120b) can receive (e.g., from base station 110) scheduling information (e.g., on the PDCCH) including one or more SIBs of OSI within the search space. This search space may be referred to as Type 0A-PDCCH CSS. The Type 0A-PDCCH CSS can use a corresponding SSB (e.g., as combined with...) Figure 4(as described) and / or corresponding RMSI (e.g., as in combination) Figure 5A and 5B Defined by the description.
[0103] In some respects, base station 110 can be configured between the SSB and the Type 0A-PDCCH CSS with the same multiplexing mode as that configured between the SSB and the Type 0-PDCCH CSS (e.g., as combined). Figure 5A and 5B (As described). For example, base station 110 may set the searchSpaceOtherSystemInformation field (e.g., as defined in 3GPP specifications and / or another standard) or another similar field included in the RMSI to zero to indicate that UE 120a and UE 120b may use the same CSS and CORESET as UE 120a and UE 120b for receiving scheduling information for the RMSI. Accordingly, base station 110 may time-multiplex the OSI and the RMSI.
[0104] As an alternative, and as Figure 6 As shown, base station 110 can be configured with a new multiplexing mode between SSB and Type 0A-PDCCH CSS. As shown in Example 600, the transmitted SSB (e.g., as...) Figure 6 As shown, SSBs with indices 0, 2, and 3 can be mapped to one or more monitoring times (e.g., two monitoring times in Example 600) that base station 110 can use to transmit (e.g., on the PDCCH) scheduling information for OSI. These one or more monitoring times can be in one or more downlink time slots in which UE 120a and UE 120b can receive OSI. Additionally, in some aspects, these one or more downlink time slots can differ from the one or more uplink time slots used by UE 120a and UE 120b to transmit to base station 110.
[0105] As an alternative, base station 110 can use RMSI to configure a random access channel (RACH) and / or another channel so that UE 120a and UE 120b can transmit system information request messages and receive OSI in response to those request messages. For example, base station 110 can transmit scheduling information on the RACH for UE 120a and UE 120b to receive OSI on that RACH.
[0106] As indicated above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 The example described.
[0107] Generally, a base station transmits the same RMSI for each SSB used for base station broadcasting. Similarly, a base station generally uses the RMSI to transmit the same OSI for each SSB used for that base station broadcasting. However, in some cases, a base station can form different beams that benefit from coverage enhancements (such as different random access procedure configurations and / or different paging configurations, etc.). The techniques and apparatus described herein enable a base station (e.g., base station 110) to transmit system information differently for different synchronization signals (e.g., SSBs) and thus for different beams (e.g., as combined with...). Figure 6 As a result, base station 110 can configure different UEs (e.g., UE 120a and / or UE 120b) (which select different SSBs to use with base station 110) to have different random access procedure configurations and / or different paging configurations using different OSIs. Accordingly, base station 110 and UEs 120A and 120b experience increased communication reliability and / or quality.
[0108] Figure 7 This is a diagram illustrating example 700 associated with beam-related system information according to this disclosure. For example... Figure 7 As shown, Example 700 includes communication between base station 110, UE 120a, and UE 120b. In some aspects, base station 110, UE 120a, and UE 120b may be included in a wireless network (such as wireless network 100). Base station 110 and UE 120a may communicate on a radio access link, which may include an uplink and a downlink. Similarly, base station 110 and UE 120b may communicate on a radio access link, which may include an uplink and a downlink.
[0109] like Figure 7 As further shown, base station 110 can use multiple beams on wireless network 100 (e.g., as combined) Figure 3 (As described in the example 700). In example 700, base station 110 may use a first beam 705a with UE 120a and a second beam 705b with UE 120b. For example, UE 120a may measure a first synchronization signal associated with the first beam 705a (e.g., as combined with...). Figure 4 The described SSB) and the second synchronization signal associated with the second beam 705b (e.g., as combined with Figure 4The UE120b can measure a first synchronization signal associated with the first beam 705a and a second synchronization signal associated with the second beam 705b, and determine whether to use the second beam 705b based at least in part on these measurements. Although the description herein focuses on two beams, the description is similarly applicable to additional beams (e.g., three beams, four beams, etc.). Figure 8 (as described herein). Additionally or alternatively, although the description herein focuses on two-dimensional beams, the description is similarly applicable to three-dimensional beams (e.g., as combined with...). Figure 8 (As described).
[0110] As described above, base station 110 can transmit and UE 120a can receive a first synchronization signal associated with the first beam 705a. For example, UE 120a can receive an SSB associated with the first beam 705a (e.g., as combined with...). Figure 4 (As described). Accordingly, in some aspects, UE 120a can decode the SSB to obtain the MIB and the CORSET for receiving scheduling information for the RMSI (e.g., as combined with...). Figure 4 (As described).
[0111] Similarly, as described above, base station 110 can transmit and UE 120b can receive a second synchronization signal associated with the second beam 705b. For example, UE 120b can receive an SSB associated with the second beam 705b (e.g., as combined with...). Figure 4 (As described). Accordingly, in some aspects, UE 120b can decode the SSB to obtain the MIB and the CORSET for receiving scheduling information for the RMSI (e.g., as combined with...). Figure 4 (As described).
[0112] In some respects, base station 110 can transmit scheduling information at least partially based on the first synchronization signal, and UE 120a can receive scheduling information at least partially based on the first synchronization signal. For example, UE 120a can decode the SSB associated with the first beam 705a (e.g., as combined with...). Figure 5A and 5B (as described) to obtain scheduling information (e.g., RMSI). In some aspects, the scheduling information may indicate the CORESET for receiving OSI.
[0113] Similarly, base station 110 can transmit scheduling information at least partially based on the second synchronization signal, and UE 120b can receive scheduling information at least partially based on the second synchronization signal. For example, UE 120b can decode the SSB associated with the second beam 705b (e.g., as combined with...). Figure 5A and 5B (as described) to obtain scheduling information (e.g., RMSI). In some aspects, the scheduling information may indicate the CORESET for receiving OSI.
[0114] In some respects, scheduling information can be associated with both the first and second beams. For example, RMSI can be shared for both the first and second beams.
[0115] Base station 110 can transmit first system information associated with first beam 705a based at least in part on scheduling information, and UE 120a can receive the first system information associated with first beam 705a based at least in part on scheduling information. For example, the first system information may include the OSI associated with first beam 705a (e.g., as combined with...). Figure 6 (As described).
[0116] Similarly, base station 110 can transmit second system information associated with second beam 705b at least in part based on scheduling information, and UE 120b can receive second system information associated with second beam 705b at least in part based on scheduling information. For example, the second system information may include the OSI associated with second beam 705b (e.g., as combined with...). Figure 6 (As described).
[0117] In some respects, the first system information and the second system information can be different. Accordingly, the content of the first system information can differ from the content of the second system information.
[0118] For example, the first system information may indicate at least one first parameter associated with a random access procedure, which is different from at least one second parameter indicated by the second system information. The at least one first parameter may include random access repeats for the random access preamble, random access repeats for the random access response (RAR), the length of the RAR window, and / or the number of segments for the RAR window, etc. Accordingly, the first system information may indicate more repeats, a longer RAR window, and / or additional segments for the RAR, etc., so that the coverage of random access transmission using the first beam 705a is improved compared to the coverage of random access transmission using the second beam 705b. Additionally or alternatively, the first system information may include at least one first parameter associated with a paging procedure, which is different from at least one second parameter indicated by the second system information. The at least one first parameter may include a time period associated with the paging procedure and / or repeats associated with the paging procedure, etc. Accordingly, the first system information may indicate shorter time periods and / or more repetitions, etc., so that the coverage of paging transmission using the first beam 705a is improved compared to the coverage of paging transmission using the second beam 705b.
[0119] Alternatively, UE 120a may use one or more first receiving parameters to receive first system information, which are different from one or more second receiving parameters used by UE 120b to receive second system information. Accordingly, the method of transmitting the first system information may differ from the method of transmitting the second system information.
[0120] For example, one or more first reception parameters may include repetitions associated with the first system information and / or time periods associated with the first system information, etc. Accordingly, base station 110 may transmit the first system information with more repetitions and / or shorter time periods, etc., so that the coverage of the first system information transmitted using the first beam 705a is improved compared to the coverage of the second system information transmitted using the second beam 705b.
[0121] By using, such as combination Figure 7 According to the described technology, base station 110 can transmit system information (e.g., OSI) with different content and / or different transmission methods for different beams. As a result, base station 110 can configure different UEs (e.g., UE120a and / or UE120b) with different random access protocol configurations and / or different paging configurations to increase the reliability and / or quality of communication between base station 110 and these different UEs.
[0122] As indicated above, Figure 7This is provided as an example. Other examples may differ from the one provided. Figure 7 The example described.
[0123] Figure 8 This is a diagram illustrating example 800 associated with beam-related system information according to this disclosure. For example... Figure 8 As shown, Example 800 includes communication between base station 110, UE 120a, UE 120b, UE 120c, and UE 120d. In some aspects, base station 110, UE 120a, UE 120b, UE 120c, and UE 120d may be included in a wireless network (such as wireless network 100). Base station 110 and UE 120a may communicate on a radio access link, which may include an uplink and a downlink. Similarly, base station 110 and UE 120b may communicate on a radio access link, base station 110 and UE 120c may communicate on a radio access link, and base station 110 and UE 120d may communicate on a radio access link.
[0124] like Figure 8 As further shown, base station 110 can use multiple beams on wireless network 100 (e.g., as combined) Figure 3 (As described in the example 800). In example 800, base station 110 can use a first beam 805a with UE 120a, a second beam 805b with UE 120b, a third beam 805c with UE 120c, and a fourth beam 805d with UE 120d. For example, UE 120a can measure a first synchronization signal associated with the first beam 805a (e.g., as combined with...). Figure 4 The described SSB), and the second synchronization signal associated with the second beam 805b (e.g., as combined with Figure 4 The described SSB), and the third synchronization signal associated with the third beam 805c (e.g., as combined with Figure 4 The described SSB) and the fourth synchronization signal associated with the fourth beam 805d (e.g., as combined with Figure 4 The first beam 805a is determined to be used based at least in part on these measurements (as described in the SSB description). UE 120b, UE 120c, and UE 120d can perform similar procedures to select the second beam 805b, the third beam 805c, and the fourth beam 805d, respectively. Although the description herein focuses on four beams, it is similarly applicable to fewer beams (e.g., three or two beams) and / or additional beams (e.g., five, six, etc.). Additionally or alternatively, although the description herein focuses on three-dimensional beams, it is similarly applicable to two-dimensional beams (e.g., as combined with...). Figure 7 (As described).
[0125] As described above, base station 110 can transmit and UE 120a can receive a first synchronization signal associated with the first beam 805a. For example, UE 120a can receive an SSB associated with the first beam 805a (e.g., as combined with...). Figure 4 (As described). Accordingly, in some aspects, UE 120a can decode the SSB to obtain the MIB and CORSET for receiving scheduling information for RMSI (e.g., as combined with... Figure 4 (As described).
[0126] Similarly, as described above, base station 110 can transmit and UE 120b can receive a second synchronization signal associated with the second beam 805b. Additionally, base station 110 can transmit and UE 120c can receive a third synchronization signal associated with the third beam 805c. Additionally, base station 110 can transmit and UE 120d can receive a fourth synchronization signal associated with the fourth beam 805d.
[0127] In some respects, base station 110 can transmit scheduling information at least partially based on the first synchronization signal, and UE 120a can receive scheduling information at least partially based on the first synchronization signal. For example, UE 120a can decode the SSB associated with the first beam 705a (e.g., as combined with...). Figure 5A and 5B (as described) to obtain scheduling information (e.g., RMSI). In some aspects, the scheduling information may indicate the CORESET for receiving OSI.
[0128] Similarly, base station 110 may transmit scheduling information at least partially based on the second synchronization signal, and UE 120b may receive scheduling information at least partially based on the second synchronization signal. Base station 110 may further transmit scheduling information at least partially based on a third synchronization signal, and UE 120c may receive scheduling information at least partially based on the third synchronization signal. Additionally, base station 110 may transmit scheduling information at least partially based on a fourth synchronization signal, and UE 120d may receive scheduling information at least partially based on the fourth synchronization signal.
[0129] In some respects, scheduling information can be associated with the first, second, third, and fourth beams. For example, RMSI can be shared across the first, second, third, and fourth beams.
[0130] Base station 110 can transmit first system information associated with first beam 805a based at least in part on scheduling information, and UE 120a can receive the first system information associated with first beam 805a based at least in part on scheduling information. For example, the first system information may include the OSI associated with first beam 805a (e.g., as combined with...). Figure 6 (As described).
[0131] Similarly, base station 110 can transmit second system information associated with second beam 805b at least partially based on scheduling information, and UE 120b can receive the second system information associated with second beam 805b at least partially based on scheduling information. Additionally, base station 110 can transmit third system information associated with third beam 805c at least partially based on scheduling information, and UE 120c can receive the third system information associated with third beam 805c at least partially based on scheduling information. Additionally, base station 110 can transmit fourth system information associated with fourth beam 805d at least partially based on scheduling information, and UE 120d can receive the fourth system information associated with fourth beam 805d at least partially based on scheduling information.
[0132] In some respects, the information in the first system may differ from the information in the second, third, and fourth systems. Accordingly, the content of the information in the first system may differ from the content of the information in the second, third, and fourth systems.
[0133] For example, the first system information may indicate at least one first parameter associated with a random access procedure, which is different from at least one second parameter indicated by the second system information, at least one third parameter indicated by the third system information, and at least one fourth parameter indicated by the fourth system information. The at least one first parameter may include random access repeats for the random access preamble, random access repeats for the RAR, the length of the RAR window, and / or the number of segments for the RAR window, etc. Accordingly, the first system information may indicate more repeats, a longer RAR window, and / or additional segments for the RAR, etc., so that the coverage of random access transmission using the first beam 805a is improved compared to the coverage of random access transmission using the second beam 805b, the third beam 805c, and / or the fourth beam 805d. Additionally or alternatively, the first system information may indicate at least one first parameter associated with a paging procedure, which is different from at least one second parameter indicated by the second system information, at least one third parameter indicated by the third system information, and at least one fourth parameter indicated by the fourth system information. The at least one first parameter may include the time period associated with the paging procedure and / or the repetition associated with the paging procedure, etc. Accordingly, the first system information may indicate shorter time periods and / or more repetitions, etc., so that the coverage of paging transmission using the first beam 805a is improved compared to the coverage of paging transmission using the second beam 805b, the third beam 805c and / or the fourth beam 805d.
[0134] Additionally or alternatively, UE 120a may use one or more first receiving parameters to receive first system information, which are different from one or more second receiving parameters used by UE 120b to receive second system information, one or more third receiving parameters used by UE 120c to receive third system information, and one or more fourth receiving parameters used by UE 120d to receive fourth system information. Accordingly, the method of transmitting the first system information may differ from the method of transmitting the second, third, and fourth system information.
[0135] For example, one or more first reception parameters may include repetitions associated with the first system information and / or time periods associated with the first system information, etc. Accordingly, base station 110 may transmit the first system information with more repetitions and / or shorter time periods, etc., so that the coverage of the first system information transmitted using the first beam 805a is improved compared with the coverage of the second system information transmitted using the second beam 805b, the coverage of the third system information transmitted using the third beam 805c, and / or the coverage of the fourth system information transmitted using the fourth beam 805d.
[0136] In some respects, the content of the second system information may be further different from the content of the third system information and / or the content of the fourth system information. Additionally, in some respects, the content of the third system information may be further different from the content of the fourth system information. Additionally or alternatively, two or more of the content of the second system information, the content of the third system information, and the content of the fourth system information may be the same.
[0137] Additionally or alternatively, in some aspects, the method for transmitting the second system information may be further different from the method for transmitting the third system information and / or the method for transmitting the fourth system information. Additionally or alternatively, two or more of the methods for transmitting the second, third, and fourth system information may be the same.
[0138] By using, such as combination Figure 8 According to the described technology, base station 110 can transmit system information (e.g., OSI) with different content and / or different transmission methods for different beams. As a result, base station 110 can configure different UEs (e.g., UE120a, UE120b, UE120c, and UE120d) with different random access protocol configurations and / or different paging configurations to increase the reliability and / or quality of communication between base station 110 and different UEs.

Figure 13 An example of the device 1300 performing operations associated with system information related to the received beam.
[0141] like Figure 9 As shown, in some aspects, process 900 may include data from a base station (e.g., base station 110 and / or...). Figure 14 The device 1400) receives a first synchronization signal associated with the first beam (block 910). For example, the UE (e.g., using...) Figure 13 The receiving component 1302 described herein can receive a first synchronization signal associated with the first beam from the base station, as described herein.
[0142] like Figure 9As shown, in some aspects, process 900 may include receiving scheduling information from a base station based at least in part on a first synchronization signal (block 920). For example, a UE (e.g., using receiving component 1302) may receive scheduling information from a base station based at least in part on the first synchronization signal, as described herein.
[0143] like Figure 9 As further shown, in some aspects, process 900 may include receiving first system information associated with a first beam from a base station based at least in part on scheduling information (block 930). For example, a UE (e.g., using receiving component 1302) may receive the first system information associated with the first beam from a base station based at least in part on scheduling information, as described herein. In some aspects, this first system information differs from second system information associated with a second beam.
[0144] Process 900 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0147] In a third aspect, either alone or in combination with one or more of the first and second aspects, the first system information indicates at least one first parameter associated with the random access procedure, which is different from at least one second parameter indicated by the second system information.
[0148] In the fourth aspect, alone or in combination with one or more of the first to third aspects, the at least one first parameter includes random access repeat for the random access preamble, random access repeat for the RAR, the length of the RAR window, the number of segments for the RAR window, or a combination thereof.

[0152] Figure 10 This is a diagram illustrating an example process 1000 performed by a base station according to this disclosure. Example process 1000 is wherein a base station (e.g., base station 110 and / or...) Figure 14 An example of the device 1400 performing operations associated with transmission beam-related system information.
[0153] like Figure 10 As shown, in some aspects, process 1000 may include sending data to the UE (e.g., UE 120 and / or...). Figure 13 The device 1300 transmits a first synchronization signal associated with the first beam (block 1010). For example, a base station (e.g., using...) Figure 14 The transmission component 1404 described herein can transmit a first synchronization signal associated with the first beam to the UE, as described herein.

For example, a base station (e.g., using transmission component 1404) may transmit scheduling information to the UE based at least in part on the first synchronization signal, as described herein.
[0155] like Figure 10 As further shown, in some aspects, process 1000 may include transmitting first system information associated with a first beam to the UE based at least in part on scheduling information (block 1030). For example, a base station (e.g., using transmission component 1404) may transmit the first system information associated with the first beam to the UE based at least in part on scheduling information, as described herein.
