Description

[Technical field]

[0001] Aspects of the present disclosure relate generally to wireless communications. [Background technology]

[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 react quickly to changing conditions (such as the UE's movement and rotation) through beam switching by rapidly pointing the antenna's directional beam toward other devices, such as the base station. Beam switching is used in both Connected Mode Discontinuous Reception (CDRX) and non-CDRX modes of LTE. However, the performance of beam switching is limited by the antenna's resolution in tracking the UE's direction, and in CDRX mode, the UE's modem may need to wake up frequently to accurately track the UE's direction and adjust the antenna gain to improve performance. Such an increase in the modem's wake-up frequency may increase the UE's power consumption. In non-CDRX mode, the UE modem samples the received signal at a faster rate to maintain performance at the expense of increased power consumption, but such increased signal sampling may not improve detection of the correct beam during beam switching that occurs during UE rotation or movement.

[0011] Aspects of the present disclosure are provided in the following description and associated drawings, directed to various examples provided for illustrative purposes. Alternative aspects may be devised without departing from the scope of the present disclosure. Additionally, well-known elements of the present disclosure will not be described in detail or will be omitted so as not to obscure the relevant details of the present disclosure.

[0012] The words "exemplary" and / or "example" are used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" and / or "example" should not necessarily be construed as preferred or advantageous over other aspects. Similarly, the term "aspects of the present disclosure" does not require that all aspects of the present disclosure include the described feature, advantage or mode of operation.

[0013] Those skilled in the art will appreciate that the information and signals described below may be represented using any of a variety of different technologies and techniques. 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 particles, optical fields or particles, or any combination thereof, depending in part on the particular application, in part on the desired design, in part on the corresponding technology, etc.

[0014] Further, many aspects are described in terms of a sequence of actions to be performed, for example, by elements of a computing device. It will be recognized that the various actions described herein may be performed by specific circuitry (e.g., an application specific integrated circuit (ASIC)), by program instructions being executed by one or more processors, or by a combination of both. Additionally, the sequences of actions described herein may be considered to be fully embodied in any form of non-transitory computer-readable storage medium storing a corresponding set of computer instructions that, when executed, will cause or instruct the associated processors of the device to perform the functionality described herein. Thus, various aspects of the present disclosure may be embodied in a number of different forms, all of which are contemplated to fall within the scope of the claimed subject matter. In addition, for each of the aspects described herein, the corresponding form of any such aspect may be described herein, for example, as "logic configured to" perform the described actions.

[0015] The terms "user equipment" (UE) and "base station" as used herein are not intended to be specific or otherwise limited to any particular radio access technology (RAT) unless otherwise stated. In general, a UE may be any wireless communication device (e.g., a mobile phone, a router, a tablet computer, a laptop computer, a consumer asset tracking device, a wearable (e.g., a smart watch, a smart glass, an augmented reality (AR) / virtual reality (VR) headset, etc.), a vehicle (e.g., an automobile, a motorcycle, a bicycle, etc.), an Internet of Things (IoT) device, etc.) used by a user to communicate over a wireless communication network. A UE may be mobile or may be stationary (e.g., at some times) and may communicate with a radio access network (RAN). The term "UE" as used herein may be referred to interchangeably as an "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. In general, a UE may communicate with a core network via the RAN, through which the UE may be connected to external networks, such as the Internet, and to other UEs. Of course, other mechanisms for connecting to the core network and / or the Internet are also possible for a UE, such as via a wired access network, a Wireless Local Area Network (WLAN) network (e.g., based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 specifications, etc.).

[0016] A base station may operate according to one of several RATs in communication with a UE depending on the network in which the UE is deployed, and may alternatively be referred to as an access point (AP), network node, Node B, evolved Node B (eNB), next generation eNB (ng-eNB), New Radio (NR) Node B (also referred to as gNB or gNode B), etc. A base station may be used primarily to support wireless access by UEs, including supporting data, voice, and / or signaling connections for supported UEs. In some systems, a base station may provide purely edge node signaling functionality, while in other systems, a base station may provide additional control and / or network management functionality. A communication link through which a UE may send signals to a base station is referred to as an uplink (UL) channel (e.g., a reverse traffic channel, a reverse control channel, an access channel, etc.). A communication link through which a base station may send signals to a UE is referred to as a downlink (DL) channel or a forward link channel (e.g., a paging channel, a control channel, a broadcast channel, a forward traffic channel, etc.). As used herein, the term Traffic Channel (TCH) can refer to either an uplink / reverse traffic channel or a downlink / forward traffic channel.

[0017] The term "base station" may refer to a single physical transmit reception point (TRP) or multiple physical TRPs that may or may not be collocated. For example, when the term "base station" refers to a single physical TRP, the physical TRP may be an antenna of the base station corresponding to a cell (or several cell sectors) of the base station. When the term "base station" refers to multiple physical TRPs that are collocated, the physical TRPs may be an array of antennas of the base station (e.g., as in a multiple-input multiple-output (MIMO) system or when the base station employs beamforming). When the term "base station" refers to multiple physical TRPs that are not collocated, the 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 distant base station connected to a serving base station). Alternatively, a non-collocated physical TRP may be a serving base station that receives measurement reports from the UE and neighboring base stations whose reference RF signals the UE is measuring. A TRP is a point from which a base station transmits and receives wireless signals, so as used herein, references to transmission from or reception at a base station should be understood as references to the particular TRP of the base station.

[0018] In some implementations that support positioning of UEs, a base station may not support wireless access by the UE (e.g., may not support data, voice, and / or signaling connections for the UE), but instead may transmit reference signals to the UE to be measured by the UE and / or may receive and measure signals transmitted by the UE. Such a base station may be referred to as a positioning beacon (e.g., when it transmits signals to the UE) and / or a location measurement unit (e.g., when it receives and measures signals from the UE).

[0019] An "RF signal" comprises electromagnetic waves of a given frequency that transport information through space between a transmitter and a receiver. As used herein, a transmitter may transmit a single "RF signal" or multiple "RF signals" to a receiver. However, a receiver may receive multiple "RF signals" corresponding to each transmitted RF signal due to the propagation characteristics of RF signals through a multipath channel. The same transmitted RF signal on different paths between a transmitter and a receiver may be referred to as a "multipath" RF signal.

[0020] 1 illustrates an exemplary wireless communication system 100. The wireless communication system 100 (sometimes referred to as 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 an aspect, the macrocell base stations may include eNBs and / or ng-eNBs, where the wireless communication system 100 corresponds to an LTE network, or gNBs, where the wireless communication system 100 corresponds to an NR network, or a combination of both, and the small cell base stations may include femtocells, picocells, microcells, etc.

[0021] The base stations 102 may collectively form a RAN and may interface with a core network 170 (e.g., Evolved Packet Core (EPC) or 5G Core (5GC)) through the backhaul links 122 and to one or more location servers 172 (which may be part of the core network 170 or may be external to the core network 170) through the core network 170. In addition to other functions, the base stations 102 may perform functions related to one or more of forwarding 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, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, RAN sharing, multimedia broadcast multicast services (MBMS), subscriber and equipment tracing, RAN information management (RIM), paging, positioning, and distribution of alert messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through EPC / 5GC) via backhaul links 134, which may be wired or wireless.

[0022] The base stations 102 may wirelessly communicate with the UEs 104. Each of the base stations 102 may provide communication coverage to a respective geographic coverage area 110. In an aspect, one or more cells may be supported by the base stations 102 in each geographic coverage area 110. A "cell" is a logical communication entity used for communication with the base stations (e.g., over some frequency resources, referred to as a carrier frequency, component carrier, carrier, band, etc.) and may be associated with an identifier (e.g., physical cell identifier (PCI), virtual cell identifier (VCI), cell global identifier (CGI)) to distinguish cells operating over the same or different carrier frequencies. In some cases, different cells may be configured according to different protocol types (e.g., machine type communication (MTC), narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB), or others) that may provide access to different types of UEs. Because a cell is supported by a particular base station, the term "cell" may refer to one or both of the logical communication entity and the base station that supports it, depending on the context. In some cases, the term "cell" may refer to the geographic coverage area (e.g., sector) of a base station, so long as the carrier frequency can be detected and used for communication within some portion of the geographic coverage area 110.

[0023] While the geographic coverage areas 110 of neighboring macrocell base stations 102 may overlap partially (e.g., in handover regions), some of the geographic coverage areas 110 may be significantly overlapped by larger geographic coverage areas 110. For example, a small cell (SC) base station 102' may have a geographic coverage area 110' that significantly overlaps with the geographic coverage area 110 of one or more macrocell base stations 102. A network that includes both small cell and macrocell base stations may be referred to as a heterogeneous network. A heterogeneous network may also include a Home eNB (HeNB) that may serve a restricted group called a closed subscriber group (CSG).

[0024] The communication link 120 between the base station 102 and the UE 104 may include an uplink (also referred to as a reverse link) transmission from the UE 104 to the base station 102, and / or a downlink (also referred to as a forward link) transmission from the base station 102 to the UE 104. The communication link 120 may use MIMO antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link 120 may be over one or more carrier frequencies. The allocation of carriers 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 wireless local area network (WLAN) access point (AP) 150 in communication with a WLAN station (STA) 152 via a communication link 154 in an unlicensed frequency spectrum (e.g., 5 GHz). When communicating in 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 if a channel is available.

[0026] The small cell base station 102' may operate in a licensed and / or unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell base station 102' may employ LTE or NR technology and may use the same 5 GHz unlicensed frequency spectrum used by the WLAN AP 150. A small cell base station 102' employing LTE / 5G in an unlicensed frequency spectrum may extend coverage to and / or increase capacity of an access network. NR in an unlicensed spectrum may be referred to as NR-U. LTE in an unlicensed spectrum may be referred to as LTE-U, licensed assisted access (LAA), or MulteFire.

[0027] The wireless communication system 100 may further include a mmW base station 180 in communication with the UE 182 and may operate in millimeter wave (mmW) and / or sub-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 and 10 millimeters. Radio waves in this band may be referred to as millimeter waves. Sub-mmW may extend down to frequencies of 3 GHz with wavelengths of 100 millimeters. The very high frequency (SHF) band extends between 3 GHz and 30 GHz, also referred to as centimeter waves. Communications using the mmW / sub-mmW radio frequency bands have high path losses and relatively short distances. The mmW base station 180 and the UE 182 may utilize beamforming (transmit and / or receive) over the mmW communication link 184 to compensate for the extremely high path losses and short distances. It will be appreciated that in alternative configurations, one or more base stations 102 may also transmit using mmW or sub-mmW and beamforming. Therefore, it should be appreciated that the above illustrations are merely illustrative and should not be construed as limiting the various aspects disclosed herein.

[0028] Transmit beamforming is a technique for focusing an RF signal in a particular 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., UE) is located (relative to the transmitting network node) and projects a stronger downlink RF signal in that particular direction, thereby resulting in a faster and more powerful RF signal (in terms of data rate) to the receiving device. To change the directionality of an RF signal when transmitting, the network node can control the phase and relative amplitude of the RF signal at 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 creates beams of RF waves that can be "steered" to points in different directions without actually moving the antennas. In particular, RF currents from the transmitters are fed to individual antennas with the proper phase relationship so that the waves from the separate antennas add together to increase radiation in the desired direction while suppressing and eliminating radiation in undesired directions.

[0029] A transmit beam may be quasi-co-located, meaning that the transmit beam appears to a receiver (e.g., a UE) to have the same parameters, regardless of whether the network node's own transmit antennas are physically co-located or not. In NR, there are four types of quasi-co-location (QCL) relationships. In particular, a QCL relationship of a given type means that some parameters for a target reference RF signal on a target beam can be derived from information about a source reference RF signal on a 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, average 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 average 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 spatial reception parameters of a target reference RF signal transmitted on the same channel.

[0030] In receive beamforming, a receiver uses receive beams to amplify RF signals detected on a given channel. For example, the receiver can increase the gain setting and / or adjust the phase setting of an array of antennas in a particular direction to amplify (e.g., increase the gain level of) RF signals received from that direction. Thus, when a receiver is said to beamform in some direction, it means that the beam gain in that direction is larger than the beam gains along other directions, or that the beam gain in that direction is the largest compared to the beam gains in that direction of all other receive beams available to the receiver. This results in a stronger received signal strength (e.g., Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference and Noise Ratio (SINR), etc.) of RF signals received from that direction.

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

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

[0033] In 5G, the frequency spectrum in which the wireless nodes (e.g., base station 102 / 180, UE 104 / 182) operate is divided into multiple frequency ranges, namely, FR1 (from 450 MHz to 6000 MHz), FR2 (from 24250 MHz to 52600 MHz), FR3 (above 52600 MHz), and FR4 (between FR1 and FR2). In a multi-carrier system such as 5G, one of the carrier frequencies is called the "primary carrier" or "anchor carrier" or "primary serving cell" or "PCell", and the remaining carrier frequencies are called the "secondary carrier" or "secondary serving cell" or "SCell". In carrier aggregation, the anchor carrier is the carrier operating on the primary frequency (e.g., FR1) utilized by the UE 104 / 182 and the cell, and the UE 104 / 182 either performs an initial radio resource control (RRC) connection establishment procedure or initiates an RRC connection re-establishment procedure. The primary carrier carries all common and UE-specific control channels and may be a carrier among 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 UE 104 and the anchor carrier and may be used to provide additional radio resources. In some cases, the secondary carrier may be a carrier among unlicensed frequencies. Since both the primary uplink carrier and the primary downlink carrier are usually UE-specific, the secondary carrier may only include necessary signaling information and signals, e.g., signaling information and signals that are UE-specific may not be present in the secondary carrier. This means that different UEs 104 / 182 in a cell may have different downlink primary carriers. The same is true for the uplink primary carrier. The network may change the primary carrier of any UE 104 / 182 at any time. This is done, for example, to balance the load on different carriers.Since a "serving cell" (whether a PCell or an SCell) corresponds to a carrier frequency / component carrier through which several base stations are communicating, terms such as "cell", "serving cell", "component carrier", "carrier frequency", etc. may be used interchangeably.

[0034] For example, still referring to FIG. 1, one of the frequencies utilized by the macrocell base station 102 may be an anchor carrier (i.e., a "PCell"), and the other frequencies utilized by the macrocell base station 102 and / or the mmW base station 180 may be secondary carriers ("SCells"). Simultaneous transmission and / or reception of multiple carriers allows the UE 104 / 182 to significantly increase its data transmission and / or reception rates. For example, two aggregated 20 MHz carriers in a multi-carrier system would theoretically lead to a two-fold increase in data rate (i.e., 40 MHz) compared to that achieved by a single 20 MHz carrier.

[0035] The wireless communications system 100 may further include a UE 164, which may communicate with the macrocell base station 102 via communications link 120 and / or with the mmW base station 180 via an mmW communications 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 of FIG. 1, one or more Earth-orbiting satellite positioning system (SPS) space vehicles (SVs) 112 (e.g., satellites) may be used as independent sources of location information for any of the illustrated UEs (shown in FIG. 1 as a single UE 104 for simplicity). The UE 104 may include one or more dedicated SPS receivers specifically designed to receive SPS signals 124 to derive geolocation information from the SVs 112. An SPS typically includes a system of transmitters (e.g., SVs 112) positioned to enable receivers (e.g., UEs 104) to determine their location on or above the Earth based at least in part on signals (e.g., SPS signals 124) received from the transmitters. Such transmitters typically transmit signals marked with a repeating pseudorandom noise (PN) code of a set number of chips. Although typically located within the SVs 112, transmitters may sometimes be located on ground-based control stations, base stations 102, and / or other UEs 104.

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

[0038] The wireless communication system 100 may further include one or more UEs, such as UE 190, that indirectly connect to one or more communication networks via one or more device-to-device (D2D) peer-to-peer (P2P) links (referred to as "sidelinks"). In the example of FIG. 1, the UE 190 has a D2D P2P link 192 with one of the UEs 104 connected to one of the base stations 102 (e.g., through which the UE 190 may indirectly obtain cellular connectivity), and a D2D P2P link 194 with a WLAN STA 152 connected to a WLAN AP 150 (through which the UE 190 may indirectly obtain WLAN-based Internet connectivity). In one example, the 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), Bluetooth®, etc.

[0039] Referring to FIG. 2, a simplified schematic diagram of an exemplary mobile device 200 having a processor 220, an antenna array 210, a transceiver 222, and a sensor system 230 for determining location and activity information of the mobile device 200 to manage the antenna beam of the mobile device 200 during CDRX and non-CDRX modes is shown. To improve the performance of the 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 a memory 240. It should be noted that the mobile device 200 may be similar to the UE 104, 190, or any other UE shown in FIG. 1, and may further comprise one or more components as known to those skilled in the art, but not shown in FIG. 2.

[0040] The mobile device 200 may be any suitable electronic device that is mobile. For example, the mobile device 200 may be a smartphone, a tablet, a laptop, a smart watch, a transportation tracking device, etc.

[0041] The antenna array 210 includes multiple antennas for transmit beamforming and receive beamforming as described above. The antenna array 210 is coupled to a 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 for communicating (e.g., means for transmitting, means for receiving, means for measuring, means for tuning, means for refraining from transmitting, etc.) over one or more wireless communication networks (not shown), such as a NR network, a LTE network, a GSM network, etc. 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), etc., over at least one designated RAT (e.g., NR, LTE, GSM, etc.) over a wireless communication medium of interest (e.g., some set 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 (e.g., means for transmitting, means for receiving, means for measuring, means for tuning, means for refraining from transmitting, etc.) with other network nodes, such as other UEs, access points, base stations, etc., via at least one designated RAT (e.g., WiFi, LTE-D, Bluetooth, etc.) over a wireless communication medium of interest.

[0042] Additionally, transceiver 222 may include a Satellite Positioning System (SPS) receiver. The SPS receivers may each be connected to one or more antennas in antenna array 210 and may provide a 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, Navigation Satellite System of India (NAVIC), Quasi-Zenith Satellite System (QZSS), etc. The SPS receivers may comprise any suitable hardware and / or software for receiving and processing SPS signals.

[0043] The transceiver circuitry in the transceiver 222, including at least one transmitter and at least one receiver, may in some implementations comprise an integrated device (e.g., embodied as transmitter and receiver circuits in a single communications device), in some implementations comprise separate transmitter devices and separate receiver devices, or in other implementations may be embodied in other ways. In one aspect, the transmitter may include or be coupled to multiple antennas, such as the antenna array 210, that allows each device to perform transmit "beamforming," as described herein. Similarly, the receiver may include or be coupled to multiple antennas, such as the antenna array 210, that allows each device to perform receive beamforming, as described herein. In one aspect, the transmitters and receivers may share multiple identical antennas (e.g., the antenna array 210), such that each device can only receive or transmit at a given time, but not both at the same time.

[0044] As shown in FIG. 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 an aspect, the processor 220 may perform antenna beam management every 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 FIG. 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 movement detection sensor. Each of the sensors in the sensor system 230 detects and measures its respective environment and transmits the measurements as data to the processor 220. In an aspect, the processor 220 may control the operation of the sensor system 230.

[0045] In one aspect, the processor 220 may control the sensors in the sensor system 230 and may receive data from the gyroscope 232, the accelerometer 234, the magnetometer 236, and the pedometer 238. The gyroscope 232, the accelerometer 234, the magnetometer 236, and the 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, the accelerometer 234, the magnetometer 236, and the pedometer 238 when to send their respective data and thus control the timing at which data is received from the gyroscope 232, the accelerometer 234, the magnetometer 236, and the pedometer 238.

[0046] The processor 220 may use data received from the sensors (i.e., the gyroscope 232, the accelerometer 234, the magnetometer 236, and the pedometer 238) to determine location information of the mobile device 200, including at least one of an orientation, a translation, or a movement of the mobile device 200. The location information may include the angle and movement of the mobile device 200 in multiple axes, as processed by the processor 220 based on the data detected by the sensors. Moreover, the processor 220 may combine the output from the sensors to determine activity information of the mobile device 200. The activity information may include activities engaged in by a user of the mobile device 200 while in possession of the mobile device 200. For example, if a 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 a 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 aspect, the processor 220 may determine the activity information based on data received from the sensor system 230 during a period of time.

[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 position information and activity information of the mobile device 200. Such algorithms may be stored in the memory 240 and processed by the processor 220. For example, the processor 220 may use a combination of data from sensors to calculate the position of the mobile device 200 in a 2D coordinate system and / or a 3D coordinate system. The processor 220 may use the AR algorithm to determine activity information of the mobile device 200, such as walking, biking, running, riding in a vehicle, or sitting.

[0048] In one aspect, when the mobile device 200 is operating under the CDRX mode, the processor 220 may synchronize the sensor system 230 with the CDRX mode period so that the processor 220 may accurately determine the location information and activity information of the mobile device 200 at the beginning and end of each CDRX mode period. Thus, under the 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 the sensors in the sensor system 230 and processing the collected data as described below.

[0049] A timing diagram illustrating synchronization during CDRX mode is shown in FIG. 5. At time T=0 in FIG. 5, a CDRX cycle period begins and the mobile device 200 wakes up from sleep (i.e., a low power state). At T=0, the sensors in the sensor system 230 may transmit data detected by the sensors (i.e., the gyroscope 232, the accelerometer 234, the magnetometer 236, and the pedometer 238) to the processor 220. Essentially, the processor 220 may synchronize the sensor system 230, which should transmit the data detected by the sensors, with the CDRX cycle period. FIG. 5 illustrates the timing of the synchronization of the sensor system 230 with the CDRX cycle period by using a downward arrow labeled "synchronization." The processor 220 may then process the data and perform antenna beam management based on the data. Thus, when the mobile device 200 wakes up again at T=1, a new CDRX cycle period begins at T=1, so the sensor system 230 transmits new data detected by the sensors at T=1 to the processor 220. The processor 220 may then process the 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 aspect, under CDRX mode, the wake-up period for antenna beam management is aligned 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 of 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 of 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 the 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 the sensors to predict or estimate the location information of the mobile device 200, such as the direction and movement of the mobile device 200 in the future. For example, by using data collected from the sensors in the sensor system 230 at T=0, the processor 220 may predict or estimate the location information of the mobile device 200 at time T=1. In other words, the processor 220 estimates the direction, movement, or location of the mobile device 200 in the future based on the current data collected from the sensors in the sensor system 230. In an aspect, the prediction or estimation may be performed for the next CDRX cycle period. The processor 220 may predict forward by using various prediction filters that are selected based on the user activity as determined by the AR algorithm or the data from the pedometer 238.

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

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

[0054] predicted angle = predicted forward angle of the mobile device 200 in the next CDRX cycle period,

[0055] α = constant based on input from pedometer 238;

[0056] current angle = current angle of the mobile device 200,

[0057] currentGyro = current gyroscope 232 reading,

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

[0059] The above "predicted angle" equation may be used as part of the gyroscope rotation vector prediction in predicting the orientation of the mobile device 200. The above equation is only an example equation, and the processor 220 may use many other equations and algorithms to predict the position information of the mobile device 200 forward. In one aspect, the processor 220 may utilize a neural network, such as a deep learning neural network, to predict the position information of the mobile device 200 forward. In one aspect, at the beginning of the next CDRX cycle period, the processor 220 may perform antenna beam management using the forward prediction or forward estimation of the position information (i.e., orientation, movement, and / or position) of the mobile device 200 such that the mobile device 200 is ready to receive communication from a base station when the mobile device 200 wakes up from sleep in the next CDRX period.

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

[0061] In one aspect, when the mobile device 200 is operating under a 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 the non-CDRX mode, the processor 220 may flexibly change the wake-up period for antenna beam management based on the location information and activity information of the mobile device 200.

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

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

[0064] In one aspect, even when the mobile device 200 operates under the CDRX mode, the processor 220 may attempt to change the length of the CDRX cycle period based on the location information and activity information of the mobile device 200 by working with the base station serving the mobile device 200. In other words, the processor 220 may attempt to change Δt 520 shown in FIG. 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 5 ms and the user of the mobile device 200 is walking fast, the processor 220 may determine that a wake-up period of 3 ms for antenna beam management will be better to accommodate the mobile device 200 that is shifting or moving quickly. The processor 220 may communicate this information (i.e., a more suitable CDRX cycle period) to the base station so that the length of the period for the CDRX mode can be adjusted to suit the movement or activity of the mobile device 200. The base station may change the CDRX mode cycle period as recommended by the processor 220 .

[0065] In one aspect, several factors may affect the measurement accuracy of sensors in the sensor system 230 and may cause synchronization errors between the sensors 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 sensors. Such errors may be mitigated by using other input sources, such as a camera that may be included in the mobile device 200. For example, if a camera on the mobile device 200 detects a base station, the processor 220 may estimate a camera-based pose, which may provide supplemental input that may help align the sensor and align the synchronization between the sensor system 230 and the processor 220. Thus, the camera-based pose may mitigate the sensor errors.

[0066] In another example, when the mobile device 200 is located in an outdoor environment free of magnetic influences, the magnetometer 236 may provide relatively error-free readings, so the processor 220 may use the magnetometer 236 readings to reset any calculated rotation or orientation vectors to avoid error accumulation caused by gyroscopic effects.

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

[0068] The components of FIG. 2 may be implemented in a variety of ways. In some implementations, the components of FIG. 2 may be implemented in one or more circuits, such as, for example, one or more processors and / or one or more ASICs (which may include one or more processors), where each circuit may use and / or incorporate at least one memory component for storing information or executable code used by the circuit to provide its functionality. For example, some or all of the functionality represented by blocks 210-240 may be performed by the processor and memory components of mobile device 200 (e.g., by execution of appropriate code and / or by appropriate configuration of the processor components). However, as will be appreciated, such operations, acts, and / or functions may actually be performed by a particular component or combination of components of mobile device 200, such as antenna array 210, transceiver 222, processor 220, sensor system 230, and memory 240.

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

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

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

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

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

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

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

[0076] At block 335, the method adjusts the wake-up period of the mobile device based on the location information and activity information. The processor 220 may adjust the wake-up period of the mobile device 200 based on the location information and activity information of the mobile device 200. In a 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 a non-CDRX mode, the processor 220 may adjust and change the wake-up period independently without communicating with the base station.

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

[0078] In the above detailed description, it can be seen that various features are grouped together in the examples. This manner of disclosure should not be understood as an intention that the exemplary clauses have more features than are expressly stated in each clause. Rather, various aspects of the disclosure may include fewer than all features of each exemplary clause disclosed. Thus, the following clauses should be considered hereby as being incorporated into this description, and each clause may stand alone as a separate example. Although each dependent clause may refer to a specific combination with one of the other clauses in the clause, the aspects of that dependent clause are not limited to that specific combination. It will be appreciated that other exemplary clauses may also include combinations of the dependent clause aspects with the subject matter of any other dependent clause or independent clause, or any combination of features with other dependent clauses and independent clauses. Various aspects disclosed herein expressly include these combinations unless it is expressly expressed or can be easily inferred that a particular combination is not intended (e.g., contradictory aspects such as defining an element as both an insulator and a conductor). It is further contemplated that aspects of a clause may be included within any other independent clause, even if that clause is not directly dependent on an independent clause.

[0093] 4, another exemplary device 400 implemented as a wireless communication system is illustrated. The device 400 is similar in many exemplary aspects to the mobile device 200 and the UEs 104 and 190, and the illustration and description of the device 400 includes various additional exemplary components not shown that have a relationship to the mobile device 200 and the UEs 104 and 190 shown in FIGS. 1 and 2. As shown in FIG. 4, the device 400 includes a digital signal processor (DSP) 464, and a general-purpose processor illustrated as a processor 465. The functions and methods described above with respect to 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 to perform antenna beam management may be performed in the DSP 464 or the processor 465, or any combination of those processing elements. Thus, in some aspects, the processor 465 may be configured to perform the operations described with respect to the processor 220, although it will be understood that some of the operations related to managing antenna beams by determining mobile device location and activity information synchronized with wake-up periods of the mobile device may be performed in the DSP 464, and further, these operations may be implemented in any suitable combination of hardware and software. In some aspects, the processor 465 may be configured to perform antenna beam management in both CDRX and non-CDRX modes. Both the DSP 464 and the processor 465 may be coupled to the memory 460. The navigation engine 408 may be coupled to the DSP 464 and the processor 465 and used to provide location data to the DSP 464 and the processor 465. The sensors 402 may include sensors such as the gyroscope 232, the accelerometer 234, the magnetometer 236, and the pedometer 238, and may be coupled to the DSP 464 and the processor 465 and provide data to the DSP 464 and the processor 465.The display controller 426 may be coupled to the DSP 464, the processor 465, and the display 428. Other components such as a transceiver 440 (which may be part of a modem) and a receiver 441 are also shown. The transceiver 440 may be coupled to an antenna array 442, which may be configured to receive wireless signals from a calibrated terrestrial source, such as WWAN, CDMA, etc. 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 shown and may provide timing signals to the DSP 464 and the processor 465 to determine the time of day or other time-related data. In certain aspects, the DSP 464, the processor 465, the display controller 426, the memory 460, the navigation engine 408, the transceiver 440, the receiver 441, the sensor 402, and the system timer 404 are included in a system-in-package or system-on-chip device 422.

[0094] In certain aspects, the input device 430 and the power source 444 are coupled to the system-on-chip device 422. Moreover, in certain aspects, as shown in Figure 4, the display 428, the input device 430, the antenna array 442, the GNSS antenna 443, and the power source 444 are external to 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 source 444 may be coupled to a component of the system-on-chip device 422, such as an interface or a controller.

[0095] In one aspect, one or both of DSP 464 and processor 465, along with one or more of the remaining components shown in Figure 4, may include logic / means for determining location information and activity information of a mobile device synchronized with a wake-up period of the mobile device and adjusting a wake-up period based on the location information and activity information of the mobile device to perform antenna beam management, e.g., as described in blocks 305-340 of Figures 3A and 3B. For example, DSP 464, processor 220, and / or processor 465 may include logic / means for implementing functions related to synchronizing at least one sensor with a wake-up period of the mobile device, receiving data detected by the at least one sensor, determining location information based on the received data, determining activity information based on the received data, estimating a forward position of the mobile device based on the location information and activity information, and performing antenna beam management based on the location information, activity information, and forward position.
