Description

Technical Field

[0001] Aspects of the present disclosure generally relate to wireless communication.

Background Art

[0002] In wireless communication networks such as LTE (Long Term Evolution) networks, antennas are used to transmit and receive signals between devices such as base stations and UEs (user equipment). In LTE sub-6 GHz and mmWave systems, the UE needs to quickly respond to changing conditions (such as UE movement and rotation) through beam switching by rapidly directing the directional beam of the antenna towards other devices such as the base station. Beam switching is used in both LTE's connected mode discontinuous reception (CDRX) and non-CDRX modes. However, the performance of beam switching is limited by the antenna resolution when tracking the direction of the UE, and in the CDRX mode, the UE's modem may need to wake up frequently to accurately track the direction of the UE and adjust the antenna gain to improve performance. Such an increase in the wake-up frequency of the modem may increase the power consumption of the UE. In the non-CDRX mode, the UE's modem samples the received signal at a higher rate to maintain performance at the expense of increased power consumption, but such increased signal sampling may not improve the detection of the correct beam during beam switching that occurs during UE rotation or movement.

Alternative embodiments may be devised without departing from the scope of this disclosure. In addition, well-known elements of this disclosure are not described in detail or are omitted so as not to obscure the relevant details of this disclosure.

[0012] The terms “exemplary” and / or “example” are used herein to mean “acting as an example, case, or illustration.” Any aspect described herein as “exemplary” and / or “example” should not necessarily be construed as being preferable or advantageous to any other aspect. Similarly, the term “aspects of the disclosure” does not require that all aspects of the disclosure include the features, advantages, or modes of operation described herein.

[0013] Those skilled in the art will understand that the information and signals described below may be represented using any of a variety of different techniques and methods. For example, the data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the following description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or optical particles, or any combination thereof, depending in part with the specific application, in part with the desired design, in part with the corresponding technique.

It will be recognized that the various actions described herein may be performed by a particular circuit (e.g., an application-specific integrated circuit (ASIC)) by program instructions being executed by one or more processors, or a combination of both. In addition, sequences of actions described herein may be considered to be fully embodied in any form of non-temporary computer-readable storage medium storing a corresponding set of computer instructions that, at runtime, will cause or instruct the relevant processors of the device to perform the functionality described herein.

In addition, for each of the embodiments described herein, any corresponding form of such embodiment may be described herein, for example, as “logic configured to perform” the actions described.

[0015] As used herein, the terms “User Equipment” (UE) and “Base Station” are not intended to be specific to, or otherwise limited to, any particular Radio Access Technology (RAT), unless otherwise noted. Generally, a UE may be any wireless communication device used by a user to communicate over a wireless communication network (e.g., a mobile phone, router, tablet computer, laptop computer, consumer asset tracking device, wearable (e.g., smartwatch, smart glasses, augmented reality (AR) / virtual reality (VR) headset, etc.), vehicle (e.g., car, motorcycle, bicycle, etc.), Internet of Things (IoT) device, etc.). A UE may be mobile or (e.g., stationary for some time) and may communicate with a Radio Access Network (RAN). As used herein, the terms “UE” may be interchangeably referred to as “Access Terminal” or “AT,” “Client Device,” “Wireless Device,” “Subscriber Device,” “Subscriber Terminal,” “Subscriber Station,” “User Terminal” or “UT,” “Mobile Device,” “Mobile Terminal,” “Mobile Station,” or variations thereof. Generally, UEs can communicate with the core network via the RAN, and through the core network, UEs can connect to external networks such as the Internet and other UEs. Of course, other mechanisms for connecting to the core network and / or the Internet are also possible for UEs, such as via wired access networks, wireless local area network (WLAN) networks (for example, based on the IEEE 802.11 specification), etc.

[0016] A base station may operate according to one of several RATs (Network Address Terminals) through which it communicates with a UE, depending on the network in which the UE is deployed. These RATs may also be called access points (APs), network nodes, node Bs, advanced node Bs (eNBs), next-generation eNBs (ng-eNBs), or New Radio (NR) node Bs (also known as gNBs or g-node Bs). Base stations may be primarily used to support wireless access by UEs, including supporting data connectivity, voice connectivity, and / or signaling connectivity for supported UEs. In some systems, base stations may provide purely edge node signaling functionality, while in others, they may provide additional control and / or network management functionality. A communication link through which a UE can send signals to a base station is called an uplink (UL) channel (e.g., reverse traffic channel, reverse control channel, access channel, etc.). A communication link through which a base station can send signals to a UE is called a downlink (DL) channel or forward link channel (e.g., paging channel, control channel, broadcast channel, forward traffic channel, etc.). As used herein, the term Traffic Channel (TCH) may refer to either an uplink / reverse traffic channel or a downlink / forward traffic channel.

[0017] The term “base station” can refer to a single physical transmit / receive point (TRP), or to multiple physical TRPs, which may or may not be colocated. For example, if the term “base station” refers to a single physical TRP, that physical TRP may be the base station’s antennas corresponding to a cell (or several cell sectors) of the base station. If the term “base station” refers to multiple colocated physical TRPs, those physical TRPs may be an array of antennas of the base station (for example, in a multi-input multiple-output (MIMO) system, or if the base station employs beamforming). If the term “base station” refers to multiple uncolocated physical TRPs, those physical TRPs may be a distributed antenna system (DAS) (a network of spatially separated antennas connected to a common source via a transport medium), or a remote radio head (RRH) (a remote base station connected to a serving base station). Alternatively, an uncolocated physical TRP may be a UE and a serving base station receiving measurement reports from an adjacent base station where the UE is measuring its reference RF signal. Since a TRP is the point from which a base station transmits and receives wireless signals, when used herein, references to transmission from a base station or reception at a base station should be understood as referring to a specific TRP of the base station.

[0018] In some implementations that support UE positioning, a base station may not support wireless access by the UE (for example, it may not support data, voice, and / or signaling connections for the UE), but instead may transmit a reference signal to the UE to be measured by the UE, and / or receive and measure signals transmitted by the UE. Such a base station may be called a positioning beacon (for example, when transmitting a signal to the UE) and / or a location measurement unit (for example, when receiving and measuring signals from the UE).

[0019] An "RF signal" comprises an electromagnetic wave of a given frequency that transports information through the space between a transmitter and a receiver. A transmitter used herein may transmit a single "RF signal" or multiple "RF signals" to a receiver. However, due to the propagation characteristics of RF signals through multipath channels, the receiver may receive multiple "RF signals" corresponding to each transmitted RF signal. The same RF signal transmitted along different paths between the transmitter and receiver is sometimes referred to as a "multipath" RF signal.

[0020] Figure 1 shows an exemplary wireless communication system 100. The wireless communication system 100 (sometimes called a wireless wide area network (WWAN)) may include various base stations 102 and various UEs 104. The base stations 102 may include macrocell base stations (high-power cellular base stations) and / or small cell base stations (low-power cellular base stations). In one embodiment, the macrocell base station may include an eNB and / or ng-eNB where the wireless communication system 100 corresponds to an LTE network, or a gNB where the wireless communication system 100 corresponds to an NR network, or a combination of both, and the small cell base station may include femtocells, picocells, microcells, etc.

[0021] The base station 102 may collectively form a RAN and interface with the core network 170 (e.g., an advanced packet core (EPC) or a 5G core (5GC)) via a backhaul link 122, and with one or more location servers 172 (which may be part of the core network 170 or outside the core network 170) via the core network 170. In addition to other functions, the base station 102 may perform functions related to the transfer of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, delivery for non-access stratum (NAS) messages, NAS node selection, synchronization, RAN sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracing, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 can communicate with each other directly or indirectly (for example, via EPC / 5GC) via a backhaul link 134, which may be wired or wireless.

[0022] Base station 102 can wirelessly communicate with UE 104. Each of the base stations 102 can provide communication coverage to its respective geographic coverage area 110. In one aspect, one or more cells can be supported by the base stations 102 within each geographic coverage area 110. A "cell" is a logical communication entity used for communication with a base station (e.g., via several frequency resources, such as those called carrier frequency, component carrier, carrier, band, etc.), and can be associated with an identifier (e.g., Physical Cell Identifier (PCI), Virtual Cell Identifier (VCI), Cell Global Identifier (CGI)) for distinguishing cells operating via the same or different carrier frequencies. In some cases, different cells can be configured according to different protocol types (e.g., Machine Type Communication (MTC), Narrowband IoT (NB-IoT), Extended Mobile Broadband (eMBB), or others) that provide access to different types of UEs. Since a cell is supported by a particular base station, the term "cell" can, depending on the context, refer to one or both of the logical communication entity and the base station that supports it. In some cases, the term "cell" can also refer to the geographic coverage area of a base station (e.g., a sector) as long as carrier frequencies can be detected and used for communication within some parts of the geographic coverage area 110.

[0023] The geographical coverage areas 110 of adjacent macro cell base stations 102 may partially overlap (e.g., within a handover region), and some of the geographical coverage areas 110 may be significantly overlapped by a larger geographical coverage area 110. For example, a small cell (SC) base station 102' may have a geographical coverage area 110' that significantly overlaps with the geographical coverage areas 110 of one or more macro cell base stations 102. A network that includes both small cell base stations and macro cell base stations may be referred to as a heterogeneous network. The heterogeneous network may also include a home eNB (HeNB) that can provide services to a restricted group, also referred to as a closed subscriber group (CSG).

[0024] The communication link 120 between the base station 102 and the UE 104 may include uplink (also referred to as reverse link) transmission from the UE 104 to the base station 102 and / or downlink (also referred to as forward link) transmission from the base station 102 to the UE 104. The communication link 120 may use MIMO antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link 120 may be through one or more carrier frequencies. The carrier allocation may be asymmetric for the downlink and uplink (e.g., more or fewer carriers may be allocated for the downlink than for the uplink).

[0025] The wireless communication system 100 may further include a WLAN access point (AP) 150 that communicates with a WLAN station (STA) 152 via a communication link 154 within an unlicensed frequency spectrum (e.g., 5 GHz). When communicating within the unlicensed frequency spectrum, the WLAN STA 152 and / or the WLAN AP 150 may perform a clear channel assessment (CCA) or listen before talk (LBT) procedure before communicating to determine whether the channel is available.

[0026] Small cell base station 102' may operate in licensed frequency spectrum and / or unlicensed frequency spectrum. When operating in unlicensed frequency spectrum, small cell base station 102' may employ LTE or NR technology and may use the same 5GHz unlicensed frequency spectrum used by WLAN AP150. Small cell base station 102' employing LTE / 5G in unlicensed frequency spectrum may expand coverage to the access network and / or increase the capacity of the access network. NR in unlicensed spectrum is sometimes referred to as NR-U. LTE in unlicensed spectrum is sometimes referred to as LTE-U, licensed assisted access (LAA), or MulteFire.

[0027] The wireless communication system 100 communicates with UE 182 and may further include a mmW base station 180 that can operate in millimeter-wave (mmW) frequencies and / or quasi-mmW frequencies. Extremely high frequency (EHF) is the RF portion of the electromagnetic spectrum. EHF ranges from 30 GHz to 300 GHz and has wavelengths between 1 millimeter and 10 millimeters. Radio waves in this band are sometimes called millimeter waves. Quasi-mmW may extend down to frequencies up to 3 GHz with a wavelength of 100 millimeters. The very high frequency (SHF) band, also called centimeter waves, extends between 3 GHz and 30 GHz. Communication using the mmW / quasi-mmW radio frequency bands has high path loss and relatively short distances. The mmW base station 180 and UE 182 may utilize beamforming (transmit and / or receive) via the mmW communication link 184 to compensate for the extremely high path loss and short distances. Furthermore, in alternative configurations, it will be understood that one or more base stations 102 may also transmit using mmW or quasi-mmW and beamforming. Therefore, it should be understood that the above examples are merely illustrative and should not be interpreted as limiting the various embodiments disclosed herein.

[0028] Transmit beamforming is a technique for focusing RF signals in a specific direction. Traditionally, when a network node (e.g., a base station) broadcasts an RF signal, it broadcasts the signal in all directions (omnidirectionally). With transmit beamforming, the network node determines where a given target device (e.g., a UE) is located (relative to the transmitting network node) and projects a stronger downlink RF signal in that specific direction, thereby bringing a faster and more powerful RF signal (in terms of data rate) to the receiving device. To change the directivity of an RF signal when transmitting, the network node can control the phase and relative amplitude of the RF signal in each of one or more transmitters broadcasting the RF signal. For example, the network node may use an array of antennas (called a "phased array" or "antenna array") that can create beams of RF waves that can be "steered" to points in different directions without actually moving the antennas. In detail, RF currents from the transmitters are fed to individual antennas with appropriate phase relationships so that radio waves from separate antennas are added together to increase radiation in the desired direction, while radiation in undesirable directions is suppressed and removed.

[0029] A transmit beam can be quasi-co-located, meaning that to a receiver (e.g., a UE), the transmit beam appears to have the same parameters regardless of whether the transmit antenna of the network node itself is physically co-located. In NR, there are four types of quasi-co-location (QCL) relationships. In detail, a given type of QCL relationship means that several parameters of a target reference RF signal on the target beam can be derived from information about a source reference RF signal on the source beam. If the source reference RF signal is QCL type A, the receiver can use the source reference RF signal to estimate the Doppler shift, Doppler spread, mean delay, and delay spread of the target reference RF signal transmitted on the same channel. If the source reference RF signal is QCL type B, the receiver can use the source reference RF signal to estimate the Doppler shift and Doppler spread of the target reference RF signal transmitted on the same channel. If the source reference RF signal is QCL type C, the receiver can use the source reference RF signal to estimate the Doppler shift and mean delay of the target reference RF signal transmitted on the same channel. If the source reference RF signal is QCL type D, the receiver can use the source reference RF signal to estimate the spatial reception parameters of the target reference RF signal transmitted on the same channel.

[0030] In receive beamforming, a receiver uses a received beam to amplify an RF signal detected on a given channel. For example, a receiver can increase the gain setting and / or adjust the phase setting of an antenna array in a particular direction to amplify an RF signal received from that direction (for example, to increase the gain level of such an RF signal). Therefore, when a receiver is said to beamform in a certain direction, it means that the beam gain in that direction is greater than the beam gain along other directions, or that the beam gain in that direction is the maximum compared to the beam gain of all other receive beams available to the receiver in that direction. This results in a stronger received signal intensity (e.g., reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference + noise ratio (SINR), etc.) of the RF signal received from that direction.

[0031] Received beams can have spatial relationships. Spatial relationships mean that parameters for a transmit beam for a second reference signal can be derived from information about the received beam for a first reference signal. For example, a UE may use a specific receive beam to receive one or more reference downlink reference signals from a base station (e.g., positioning reference signal (PRS), tracking reference signal (TRS), phase tracking reference signal (PTRS), cell-specific reference signal (CRS), channel status information reference signal (CSI-RS), primary synchronization signal (PSS), secondary synchronization signal (SSS), synchronization signal block (SSB), etc.). The UE can then form a transmit beam to send one or more uplink reference signals (e.g., uplink positioning reference signal (UL-PRS), sounding reference signal (SRS), demodulation reference signal (DMRS), PTRS, etc.) to its base station, based on the parameters of the received beam.

[0032] It should be noted that a “downlink” beam can be either a transmit beam or a receive beam, depending on the entity forming it. For example, if a base station forms a downlink beam to transmit a reference signal to a UE, the downlink beam is a transmit beam. However, if a UE forms a downlink beam, the downlink beam is a receive beam to receive a downlink reference signal. Similarly, an “uplink” beam can be either a transmit beam or a receive beam, depending on the entity forming it. For example, if a base station forms an uplink beam, the uplink beam is an uplink receive beam, and if a UE forms an uplink beam, the uplink beam is an uplink transmit beam.

[0033] In 5G, the frequency spectrum in which wireless nodes (e.g., base stations 102 / 180, UE104 / 182) operate is divided into multiple frequency ranges: FR1 (450MHz to 6000MHz), FR2 (24250MHz to 52600MHz), FR3 (above 52600MHz), and FR4 (between FR1 and FR2). In multi-carrier systems such as 5G, one of the carrier frequencies is called the "primary carrier" or "anchor carrier" or "primary serving cell" or "PCell," while the remaining carrier frequencies are called "secondary carriers" or "secondary serving cells" or "SCell." In carrier aggregation, the anchor carrier is the carrier operating on the primary frequency (e.g., FR1) used by UE104 / 182 and the cell, and UE104 / 182 either performs the initial radio resource control (RRC) connection establishment procedure or initiates the RRC connection re-establishment procedure. The primary carrier carries all common control channels and UE-specific control channels and may be a carrier on licensed frequencies (although this is not always the case). The secondary carrier is a carrier operating on a second frequency (e.g., FR2) that may be configured once an RRC connection is established between the UE104 and the anchor carrier and may be used to provide additional radio resources. In some cases, the secondary carrier may be a carrier on unlicensed frequencies. Since both the primary uplink and primary downlink carriers are typically UE-specific, the secondary carrier may only contain the necessary signaling information and signals; for example, UE-specific signaling information and signals do not need to be present in the secondary carrier. This means that different UE104 / 182s in a cell may have different downlink primary carriers. The same applies to uplink primary carriers. The network can change the primary carrier of any UE104 / 182 at any time. This is done, for example, to balance the load on different carriers.Since a "serving cell" (whether PCell or SCell) corresponds to the carrier frequency / component carrier through which several base stations are communicating, terms such as "cell," "serving cell," "component carrier," and "carrier frequency" can be used interchangeably.

[0034] For example, still referring to Figure 1, one of the frequencies used by the macrocell base station 102 may be the anchor carrier (i.e., "PCell"), and the other frequencies used by the macrocell base station 102 and / or the mmW base station 180 may be the secondary carriers ("SCell"). Simultaneous transmission and / or reception of multiple carriers allows UE 104 / 182 to significantly increase its data transmission rate and / or data reception rate. For example, aggregated two 20MHz carriers in a multicarrier system would theoretically result in a doubling of the data rate (i.e., 40MHz) compared to what would be achieved with a single 20MHz carrier.

[0035] The wireless communication system 100 may further include a UE 164 capable of communicating with a macrocell base station 102 via a communication link 120 and / or with an mmW base station 180 via an mmW communication link 184. For example, the macrocell base station 102 may support a PCell and one or more SCells for the UE 164, and the mmW base station 180 may support one or more SCells for the UE 164.

[0036] In the example in Figure 1, one or more Earth-orbiting satellite positioning system (SPS) space vehicles (SV) 112 (e.g., satellites) may be used as an independent source of location information for any of the illustrated UEs (shown in Figure 1 as a single UE 104 for simplicity). UE 104 may include one or more dedicated SPS receivers specifically designed to receive SPS signals 124 for deriving geolocation information from SV 112. SPS typically includes a system of transmitters (e.g., SV 112) arranged to enable receivers (e.g., UE 104) to determine their locations on or above Earth, at least in part, based on signals (e.g., SPS signals 124) received from the transmitters. Such transmitters typically transmit signals marked with a set number of repeating pseudo-random noise (PN) codes. While usually located within SV 112, transmitters may sometimes be located on ground-based control stations, base stations 102, and / or other UE 104.

[0037] The use of the SPS signal 124 may be associated with use involving one or more global and / or regional navigation satellite systems, or may be otherwise enabled for such use, and may be augmented by various satellite-based augmentation systems (SBAS). For example, an SBAS may include augmentation systems that provide integrity information, differential corrections, etc., such as the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS), the Multifunction Satellite Augmentation System (MSAS), the Global Positioning System (GPS)-assisted Geoaugmented Navigation, or the GPS and Geoaugmented Navigation System (GAGAN). Thus, the SPS used herein may include any combination of one or more global and / or regional navigation satellite systems and / or augmentation systems, and the SPS signal 124 may include the SPS, SPS-like signals, and / or other signals associated with one or more such SPS.

[0038] The wireless communication system 100 may further include one or more UEs, such as UE190, that indirectly connect to one or more communication networks via one or more D2D peer-to-peer (P2P) links (referred to as “sidelinks”). In the example in Figure 1, UE190 has a D2D P2P link 192 with one of the UEs 104 connected to one of the base stations 102 (through which UE190 may indirectly obtain cellular connectivity, for example), and a D2D P2P link 194 with a WLAN STA 152 connected to a WLAN AP 150 (through which UE190 may indirectly obtain WLAN-based internet connectivity). In one example, D2D P2P links 192 and 194 may be supported using any well-known D2D RAT, such as LTE Direct (LTE-D), WiFi Direct (WiFi-D), or Bluetooth®.

[0039] Referring to Figure 2, a simplified schematic diagram of an exemplary mobile device 200 is shown, which has a processor 220, an antenna array 210, a transceiver 222, and a sensor system 230 for determining the location and activity information of the mobile device 200 in order to manage the antenna beam of the mobile device 200 between CDRX mode and non-CDRX mode. To improve the performance of antenna beam management, the wake-up period of the mobile device 200 may be adjusted based on the location and activity information. The mobile device 200 further comprises memory 240. Note that the mobile device 200 may be similar to UE 104, 190, or any other UE shown in Figure 1, and may further comprise one or more components that are known to those skilled in the art but are not shown in Figure 2.

[0040] The mobile device 200 may be any suitable mobile electronic device. For example, the mobile device 200 may be a smartphone, tablet, laptop, smartwatch, or shipping tracking device.

[0041] The antenna array 210 includes multiple antennas for transmit beamforming and receive beamforming as described above. The antenna array 210 is coupled to the transceiver 222. The processor 220 may control the antenna array 210 and the transceiver 222. The transceiver 222 may include a wireless wide area network (WWAN) transceiver that provides means (e.g., means for transmitting, means for receiving, means for measuring, means for tuning, means for refraining from transmitting, etc.) for communicating over one or more wireless communication networks (not shown), such as an NR network, an LTE network, or a GSM network. The WWAN transceiver may be connected to one or more antennas in the antenna array 210 to communicate with other network nodes such as other UEs, access points, base stations (e.g., eNBs, gNBs) over at least one designated RAT (e.g., NR, LTE, GSM, etc.) over a target wireless communication medium (e.g., several sets of time / frequency resources in a particular frequency spectrum). The transceiver 220 may further include a wireless local area network (WLAN) transceiver. The WLAN transceiver may be connected to one or more antennas in the antenna array 210 and may provide means for communicating with other network nodes such as other UEs, access points, and base stations via at least one designated RAT (e.g., WiFi, LTE-D, Bluetooth®, etc.) on the target wireless communication medium (e.g., means for transmitting, means for receiving, means for measuring, means for tuning, means for refraining from transmitting, etc.).

[0042] In addition, the transceiver 222 may include a satellite positioning system (SPS) receiver. Each SPS receiver may be connected to one or more antennas in the antenna array 210 and may provide means for receiving and / or measuring SPS signals, such as Global Positioning System (GPS) signals, Global Navigation Satellite System (GLONASS) signals, Galileo signals, Beidou signals, Indian Regional Navigation Satellite System (NAVIC), and Quasi-Zenith Satellite System (QZSS). The SPS receiver may have any suitable hardware and / or software for receiving and processing SPS signals.

[0043] The transceiver circuit configuration in the transceiver 222, which includes at least one transmitter and at least one receiver, may in some implementations comprise an integrated device (e.g., embodied as the transmitter and receiver circuits of a single communication device), in some implementations comprise separate transmitter and receiver devices, or in other implementations may be embodied in other ways. In one embodiment, the transmitter may include or be coupled to a plurality of antennas, such as an antenna array 210, which enables each device to perform transmit "beamforming" as described herein. Similarly, the receiver may include or be coupled to a plurality of antennas, such as an antenna array 210, which enables each device to perform receive beamforming as described herein. In one embodiment, the transmitter and receiver may share a plurality of the same antennas (e.g., an antenna array 210), such that each device can either receive or transmit only at a given time, and not both at the same time.

[0044] As shown in Figure 2, the processor 220 is coupled to the transceiver 222. The processor 220 may control the transceiver 222 and the antenna array 210 to perform antenna beam management. In one embodiment, the processor 220 may perform antenna beam management for each wake-up period of the mobile device 200. For example, if the processor 220 performs antenna beam management every 10 ms, the wake-up period for the mobile device 200 is 10 ms. The processor 220 is also coupled to the memory 240 and the sensor system 230, as shown in Figure 2. The sensor system 230 includes sensors such as a gyroscope 232, an accelerometer 234, a magnetometer 236, a pedometer 238, and any other type of motion detection sensor. Each of the sensors in the sensor system 230 detects and measures its respective environment and transmits the measured values ​​as data to the processor 220. In one embodiment, the processor 220 may control the operation of the sensor system 230.

[0045] In one embodiment, the processor 220 may control the sensors in the sensor system 230 and receive data from a gyroscope 232, an accelerometer 234, a magnetometer 236, and a pedometer 238. The gyroscope 232, accelerometer 234, magnetometer 236, and pedometer 238 may provide their respective data to the processor 220 as instructed by the processor 220. In other words, the processor 220 may instruct the gyroscope 232, accelerometer 234, magnetometer 236, and pedometer 238 when to send their respective data, and thus control the timing of data reception from the gyroscope 232, accelerometer 234, magnetometer 236, and pedometer 238.

[0046] The processor 220 may use data received from sensors (i.e., gyroscope 232, accelerometer 234, magnetometer 236, and pedometer 238) to determine the location information of the mobile device 200, including at least one of the orientation, translation, or motion of the mobile device 200. The location information may include the angles and translation of the mobile device 200 in multiple axes, which are processed by the processor 220 based on the data detected by the sensors. In addition, the processor 220 may combine the outputs from the sensors to determine the activity information of the mobile device 200. The activity information may include activities that the user of the mobile device 200 engaged in while possessing the mobile device 200. For example, if the user of the mobile device 200 is walking with the mobile device 200, the activity information determined by the processor 220 may include "walking". If the user of the mobile device 200 is running with the mobile device 200, the activity information determined by the processor 220 may include "running". In one embodiment, the processor 220 may determine activity information based on data received from the sensor system 230 during a certain time period.

[0047] The processor 220 may use algorithms such as a rotation vector algorithm, a game rotation vector algorithm, or an activity recognition (AR) algorithm to determine the location and activity information of the mobile device 200. Such algorithms may be stored in memory 240 and processed by the processor 220. For example, the processor 220 may use a combination of data from sensors to calculate the location of the mobile device 200 in a 2D coordinate system and / or a 3D coordinate system. The processor 220 may use an AR algorithm to determine the activity information of the mobile device 200, such as walking, cycling, running, riding in a vehicle, or sitting.

[0048] In one embodiment, when the mobile device 200 is operating under CDRX mode, the processor 220 may synchronize the sensor system 230 with the CDRX mode period so that the processor 220 can accurately determine the location and activity information of the mobile device 200 at the beginning and end of each CDRX mode period. Therefore, under CDRX mode, the processor 220 may align the wake-up period for antenna beam management with the CDRX mode cycle period. In other words, at the beginning of every CDRX mode cycle period, the processor 220 may perform antenna beam management by collecting data from sensors in the sensor system 230 and processing the collected data as described below.

[0049] Figure 5 shows a timing diagram illustrating synchronization during CDRX mode. At time T=0 in Figure 5, the CDRX cycle period begins, and the mobile device 200 wakes up from sleep (i.e., low-power state). At T=0, the sensors in the sensor system 230 (i.e., the gyroscope 232, accelerometer 234, magnetometer 236, and pedometer 238) may send data detected by the sensors to the processor 220. Essentially, the processor 220 may synchronize the sensor system 230, which should send the data detected by the sensors, with the CDRX cycle period. Figure 5 shows the timing of the synchronization of the sensor system 230 with the CDRX cycle period by using a downward arrow labeled "Synchronize". The processor 220 may then process the data and perform antenna beam management based on the data. Therefore, when the mobile device 200 wakes up again at T=1, a new CDRX cycle period begins at T=1, and the sensor system 230 sends new data detected by the sensors at T=1 to the processor 220. Next, the processor 220 may process new data and perform antenna beam management based on the new data. As shown in Figure 5, this occurs at T=2, T=3, etc. In one embodiment, under CDRX mode, the wake-up period for antenna beam management coincides with the CDRX mode cycle period.

[0050] After receiving data from the sensor, but before the start of the next CDRX cycle period, the processor 220 may use the data received from the sensor to determine and generate location and activity information for the mobile device 200. The processor 220 may use various algorithms as described above (such as a rotation vector algorithm or an AR algorithm) to generate location and activity information for the mobile device 200. The processor 220 may then use the location and activity information to perform antenna beam management, such as transmit beamforming and receive beamforming, using the antennas in the antenna array 210. For example, the processor 220 may use rotation vectors generated from the data detected by the sensor to perform transmit beamforming and receive beamforming using the antennas in the antenna array 210.

[0051] In addition, the processor 220 may use data from sensors to predict or estimate the location of the mobile device 200, such as its orientation and movement in the future. For example, by using data collected from sensors in the sensor system 230 at time T=0, the processor 220 may predict or estimate the location of the mobile device 200 at time T=1. In other words, the processor 220 estimates the orientation, movement, or location of the mobile device 200 in the future based on current data collected from sensors in the sensor system 230. In one embodiment, the prediction or estimation may be made for the next CDRX cycle period. The processor 220 may make predictions by using various predictive filters selected based on user activity, such as determined by an AR algorithm or data from the pedometer 238.

[0052] For example, if the processor 220 determines, by using an AR algorithm or a pedometer 238, that the user of the mobile device 200 is walking while staring at the phone, the processor 220 may predict the angle of the mobile device 200 in the next CDRX cycle period by using a linear predictor such as the following:

[0053] Predicted angle = α * current angle + (1 - α) * currentGyro * Δt, where,

[0054] Predicted angle = Forward predicted angle of mobile device 200 during the next CDRX cycle period.

[0055] α = a constant based on input from 238 pedometers.

[0056] Current angle = Current angle of mobile device 200,

[0057] currentGyro = Current gyroscope 232 reading,

[0058] Δt = change in time. For example, in CDRX mode, this could be one CDRX cycle period.

[0059] The above “predicted angle” formula may be used as part of gyroscope rotation vector prediction when predicting the orientation of the mobile device 200. The above formula is merely illustrative, and the processor 220 may use many other formulas and algorithms to forward predict the location of the mobile device 200. In one embodiment, the processor 220 may utilize a neural network, such as a deep learning neural network, to forward predict the location of the mobile device 200. In one embodiment, at the start of the next CDRX cycle period, the processor 220 may perform antenna beam management using forward prediction or forward estimation of the location of the mobile device 200 (i.e., orientation, motion, and / or position) so that when the mobile device 200 wakes up from sleep in the next CDRX period, the mobile device 200 is ready to receive communications from the base station.

[0060] However, if the forward prediction or estimation exceeds a certain threshold, the processor 220 may perform asynchronous collection of data from the sensors in the sensor system 230. As shown in Figure 5, at time 510 between T=2 and T=3, the forward prediction or estimation of the location information of the mobile device 200 determined at time T=2 exceeds a certain threshold, so the processor 220 may collect data detected by the sensors in the sensor system 230, even though the time at 510 does not coincide with the beginning of the CDRX cycle period. For example, such an event may occur when the user of the mobile device 200 picks it up to use it from a stationary position, such as on a desk. When the mobile device 200 moves rapidly, the forward prediction of the location information may exceed a certain threshold. When such an event occurs, the processor 220 may need to quickly perform antenna beam management before the next CDRX cycle period. Therefore, the processor 220 may perform asynchronous antenna beam management when the forward prediction or estimation exceeds a certain threshold. In other words, in one embodiment, the processor 220 may perform asynchronous antenna beam management when forward prediction or estimation exceeds a certain threshold by first performing asynchronous collection of data from sensors in the sensor system 230 and then using the asynchronously collected data to perform antenna beam management.

[0061] In one embodiment, when the mobile device 200 is operating under non-CDRX mode, the processor 220 may use a wake-up period for antenna management that does not coincide with any CDRX mode cycle period. Under non-CDRX mode, the processor 220 may flexibly change the wake-up period for antenna beam management based on the location and activity information of the mobile device 200.

[0062] For example, if the processor 220 determines that the user of mobile device 200 is walking slowly with the mobile device 200, the processor 220 may need to perform antenna beam management every 5ms (i.e., the wake-up period is 5ms), but if the mobile device 200 is stationary on a desk, the processor 220 may need to perform antenna beam management every 10ms (i.e., the wake-up period is longer at 10ms because the mobile device 200 is stationary). If the user of mobile device 200 is walking at a fast pace, the processor 220 may need to perform antenna beam management every 2ms, because the mobile device 200 is moving at a faster speed and therefore its orientation may change at a faster speed. Thus, when the mobile device 200 is operating under non-CDRX mode, the processor 220 may vary the wake-up period for antenna beam management based on location and activity information, such as the orientation, movement, position, and / or activity of the mobile device 200 as determined by the processor 220. As described above, the processor 220 may determine the location and activity information of the mobile device 200 based on data detected by sensors in the sensor system 230 for each wake-up period. Basically, even under non-CDRX mode, the processor 220 may follow the procedure outlined above for CDRX mode, but under non-CDRX mode, the processor 220 may flexibly change the wake-up period for antenna beam management based on the location and activity information of the mobile device 200.

[0063] In one embodiment, the processor 220 may record wake-up periods for various location and activity information of the mobile device 200 in memory 240 in a table or codebook format. The processor 220 may refer to such table or codebook in the future to help determine new wake-up periods.

[0064] In one embodiment, even when the mobile device 200 is operating under CDRX mode, the processor 220 may, in conjunction with the base station servicing the mobile device 200, attempt to change the length of the CDRX cycle period based on the location and activity information of the mobile device 200. In other words, the processor 220 may attempt to change Δt520 as shown in Figure 5. If the processor 220 determines that the current CDRX cycle period is too long or too short to accommodate the activity of the mobile device 200, the processor 220 may communicate this information to the base station to adjust the CDRX cycle period. For example, if the current CDRX cycle period is 5ms and the user of the mobile device 200 is walking quickly, the processor 220 may determine that a 3ms wake-up period for antenna beam management would be better to accommodate the rapidly shifting or moving mobile device 200. The processor 220 may communicate this information (i.e., a more appropriate CDRX cycle period) to the base station so that the length of the period for CDRX mode can be adjusted to suit the movement or activity of the mobile device 200. The base station may modify the CDRX mode cycle duration as recommended by processor 220.

[0065] In one embodiment, several factors may affect the measurement accuracy of the sensor in the sensor system 230 and may cause synchronization errors between the sensor and the processor 220. Factors such as sensor bias, sensor sensitivity, antenna mismatch, and system-level synchronization errors may cause errors in the measurement accuracy of the sensor. Such errors may be mitigated by using other input sources, such as a camera, which may be included in the mobile device 200. For example, if the camera on the mobile device 200 detects a base station, the processor 220 may estimate a camera-based pose, which may provide a supplementary input that can help adjust the sensor and synchronize the sensor system 230 and the processor 220. Thus, a camera-based pose may mitigate sensor errors.

[0066] In another example, when the mobile device 200 is located in an outdoor environment free from magnetic influences, the magnetometer 236 may provide a relatively error-free reading, and therefore the processor 220 may use the magnetometer 236 reading to reset any calculated rotation or direction vector in order to avoid error accumulation caused by the gyroscopic effect.

[0067] In one embodiment, errors caused by sensor drift in the sensor system 230 can be reduced by calculating relative pose estimates (i.e., a combination of directional and translation estimates) measured by the sensor after every update to the processor 220, in order to avoid long-term error accumulation. The processor 220 may utilize these relative pose estimates to assist in antenna beam management.

[0068] The components in Figure 2 may be implemented in various ways. In some implementations, the components in Figure 2 may be implemented by one or more circuits, such as one or more processors and / or one or more ASICs (which may include one or more processors). Here, each circuit may use and / or incorporate at least one memory component for storing information or executable code used by the circuit to provide this functionality. For example, some or all of the functionality represented by blocks 210-240 may be performed by the processor and memory components of the mobile device 200 (for example, by the execution of appropriate code and / or by appropriate configuration of processor components). However, as should be understood, such actions, behaviors, and / or functions may actually be performed by specific components or combinations of components of the mobile device 200, such as the antenna array 210, transceiver 222, processor 220, sensor system 230, and memory 240.

[0069] It will be understood that embodiments include various methods for performing the processes, functions, and / or algorithms disclosed herein. For example, Figures 3A and 3B show a method 300 for determining the location and activity information of a mobile device, synchronized with the wake-up period of the mobile device, and adjusting the wake-up period based on the location and activity information of the mobile device, in order to perform antenna beam management. The method may be performed by a device such as a mobile device 200, a processor 220, UE 104, 190, or other UEs shown in Figure 1. In one configuration, the method 300 described in Figure 3 may be performed by a mobile device 400, which is described below with reference to Figure 4.

[0070] In block 305, the method synchronizes the sensor with the wake-up period of the mobile device. The processor 220 may synchronize the sensor in the sensor system 230 with the wake-up period of the mobile device 200. In CDRX mode, the processor 220 may synchronize the sensor with the CDRX mode cycle period.

[0071] In block 310, the method receives data detected and measured by the sensors. The processor 220 may receive data detected and measured by the sensors in the sensor system 230 synchronously with the wake-up period.

[0072] In block 315, the method determines the location information of the mobile device based on data detected by the sensors. The processor 220 may determine the location information of the mobile device 200, including orientation, translation, and motion, based on data received from the sensors in the sensor system 230.

[0073] In block 320, the method determines activity information of the mobile device based on data detected by sensors. The processor 220 may determine activity information of the mobile device 200 based on data detected by sensors in the sensor system 230. Activity information may include activities that the user of the mobile device 200 engaged in while possessing the mobile device 200. For example, the processor 220 may determine whether the user was walking, running, or stationary while using or possessing the mobile device 200.

[0074] In block 325, the method estimates the forward position, i.e., the future position, of the mobile device based on location information. The processor 220 may estimate the forward position of the mobile device 200 based on location information. In CDRX mode, the processor 220 may estimate or predict the forward position of the mobile device 200 during the next CDRX mode cycle period.

[0075] In block 330, the method performs antenna beam management based on location information, activity information, and estimated forward position. The processor 220 may perform antenna beam management based on location information, activity information, and estimated forward position of the mobile device 200. The processor 220 may perform antenna beam management, such as transmit beamforming and receive beamforming, using the antennas in the antenna array 210.

[0076] In block 335, the method adjusts the wake-up period of the mobile device based on location and activity information. The processor 220 may adjust the wake-up period of the mobile device 200 based on the location and activity information of the mobile device 200. In CDRX mode, the processor 220 may communicate possible new wake-up periods to the base station so that the base station can change the length of the CDRX mode cycle period. In non-CDRX mode, the processor 220 may adjust and change the wake-up period independently without communicating with the base station.

[0077] In block 340, the method records the adjusted wake-up period and corresponding location and activity information in the mobile device's memory. The processor 220 may record the adjusted wake-up period and corresponding location and activity information in the mobile device 200's memory 240 for future reference. The recorded wake-up period and corresponding location and activity information may be recorded in a table format or a codebook format.

[0093] Referring next to Figure 4, another exemplary device 400 implemented as a wireless communication system is illustrated. Device 400 is similar in many exemplary embodiments to the mobile device 200 and UEs 104 and 190, and the illustration and description of device 400 include various additional exemplary components, not shown, that have relationships with the mobile device 200 and UEs 104 and 190 shown in Figures 1 and 2. As shown in Figure 4, device 400 includes a digital signal processor (DSP) 464 and a general-purpose processor illustrated as processor 465. The functions and methods described above relating to determining the location and activity information of the mobile device, synchronized with the wake-up period of the mobile device, and adjusting the wake-up period based on the location and activity information of the mobile device, in order to perform antenna beam management, may be performed in the DSP 464 or processor 465 or any combination of their processing elements. Therefore, in some embodiments, the processor 465 may be configured to perform the operations described with respect to the processor 220, but it will be understood that some of the operations relating to managing the antenna beam by determining the location and activity information of the mobile device, synchronized with the wake-up period of the mobile device, may be performed in the DSP 464, and furthermore, these operations may be implemented in any preferred combination of hardware and software. In some embodiments, the processor 465 may be configured to perform antenna beam management in both CDRX mode and non-CDRX mode. Both the DSP 464 and the processor 465 may be coupled to the memory 460. The navigation engine 408 can be coupled to the DSP 464 and the processor 465, and can be used to provide location data to the DSP 464 and the processor 465. The sensors 402 may include sensors such as a gyroscope 232, an accelerometer 234, a magnetometer 236, and a pedometer 238, and can be coupled to the DSP 464 and the processor 465, and can provide data to the DSP 464 and the processor 465.The display controller 426 may be coupled to the DSP 464, processor 465, and display 428. Other components such as a transceiver 440 and a receiver 441 (which may be part of a modem) are also illustrated. The transceiver 440 may be coupled to an antenna array 442, which may be configured to receive wireless signals from a calibrated ground source, such as a WWAN or CDMA. The receiver 441 may be coupled to a satellite or GNSS antenna 443, which may be configured to receive wireless signals from a satellite or GNSS signals. A system timer 404 is also illustrated and may provide timing signals to the DSP 464 and processor 465 to determine time or other time-related data. In certain embodiments, the DSP 464, processor 465, display controller 426, memory 460, navigation engine 408, transceiver 440, receiver 441, sensor 402, and system timer 404 are contained within a system-in-package or system-on-chip device 422.

[0094] In certain embodiments, the input device 430 and the power supply 444 are coupled to the system-on-chip device 422. Furthermore, in certain embodiments, as shown in Figure 4, the display 428, the input device 430, the antenna array 442, the GNSS antenna 443, and the power supply 444 are located outside the system-on-chip device 422. However, each of the display 428, the input device 430, the antenna array 442, the GNSS antenna 443, and the power supply 444 may be coupled to components of the system-on-chip device 422, such as interfaces or controllers.

[0095] In one embodiment, one or both of the DSP464 and processor465, together with one or more of the remaining components shown in Figure 4, may include logic / means for determining mobile device location and activity information synchronized with the mobile device's wake-up period, and adjusting the wake-up period based on the mobile device's location and activity information, in order to perform antenna beam management, as described, for example, in blocks 305-340 of Figures 3A and 3B. For example, the DSP464, processor220, and / or processor465 may include logic / means for performing functions relating to synchronizing at least one sensor with the mobile device's wake-up period, receiving data detected by at least one sensor, determining location information based on the received data, determining activity information based on the received data, estimating the mobile device's forward position based on the location and activity information, and performing antenna beam management based on the location, activity information, and forward position.

[0096] Figure 4 shows a wireless communication device, a DSP 464, a processor 465, and memory 460, but note that these may also be integrated into a device selected from a group consisting of a set-top box, a music player, a video player, an entertainment unit, a navigation device, a communication device, a personal digital assistant (PDA), a fixed-location data unit, or a computer. Furthermore, such a device may also be integrated on a semiconductor die.

[0097] Therefore, it will be understood from the above that at least one embodiment includes a mobile device having memory and a processor configured to synchronize at least one sensor with the wake-up period of the mobile device, receive data detected by the at least one sensor, determine location information based on the received data, determine activity information based on the received data, estimate the forward position of the mobile device based on the location information and activity information, and perform antenna beam management of the mobile device based on the location information, activity information and forward position.

[0098] The various embodiments disclosed advantageously enable a mobile device to determine its location and activity information, synchronized with the mobile device's wake-up period, in order to perform antenna beam management, and to adjust the wake-up period based on the mobile device's location and activity information.

For example, data, instructions, commands, information, signals, bits, symbols, and chips, which may be referenced throughout the above description, can be represented by voltage, electric current, electromagnetic waves, magnetic fields or magnetic particles, light fields or optical particles, or any combination thereof.

[0100] Furthermore, those skilled in the art will understand that various exemplary logic blocks, modules, circuits, and algorithmic steps described in relation to the embodiments disclosed herein can be implemented as electronic hardware, computer software, or a combination of both. To clearly demonstrate this hardware and software compatibility, various exemplary components, blocks, modules, circuits, and steps are described above in general terms with respect to their functionality. Whether such functionality is implemented as hardware or as software depends on the specific application and the design constraints imposed on the overall system.
