FUNDAMENTALS
[002] [002] The present invention generally relates to wireless communication and, more specifically, radio resource management (RRM) settings for user equipment (UEs) with activation signal receivers (WUS).
[003] [003] Wireless communications systems are widely implemented to provide various types of communication content, such as voice, video, packet data, messages, broadcast and so on. These systems may be able to support communication with multiple users by sharing the available system resources (eg, time, frequency and power). Examples of such multiple access systems include fourth generation (4G) systems such as Long Term Evolution Systems (LTE) or LTE-Advanced systems (LTE-A), and fifth generation (5G) systems that can be referred to as new radio systems (NR). These systems can employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or transformed discrete Fourier-scattering-OFDM (DFT-S-OFDM). A wireless multiple access communications system can include a number of base stations or network access nodes, each simultaneously supporting communication to multiple communication devices, which may otherwise be known as UES.
[004] [004] In a wireless communications system, a base station can signal to a UE that data and / or system information is available when sending alert messages during alert occasions (POs). A UE can monitor an alert occasion, for example, in a particular sub-frame, to receive an alert message and determine what alert information and / or system information is available to the UE. In some cases, the base station and the UE may use an energy-saving signal, such as Um WUS, to idle alert. For example, the UE may wake up from an inactive state after receiving the WUS and monitor transmissions on the downlink (such as an alert message) from the base station. However, network errors or interference within the system can lead to the receipt of lost WUS by the UE, which can result in the failed detection of alert messages that indicate important changes to system information, thus impairing the UE's Performance. SUMMARY
[005] [005] The techniques described refer to improved methods, systems, devices or devices that support a configuration of a radio resource management (RRM) for user equipment (UEs) with activation signal receivers (WUS). In some cases, a base station may signal a change in system information to an UE through an alert or alert message. The alert message can lead to an indication of a change in system information and also indicate that the alert information is available for one or more UEs associated with the base station. A UE can periodically monitor alert messages transmitted from the base station during alert occasions (POs). A PO can be a transmission time interval (TTI) (such as a subframe), where a downlink channel, such as a physical downlink control channel (PDCCH) or shared physical downlink channel (PDSCH), door to door alert message. In addition, a base station can use a WUS during the alert idle to indicate whether the UE should decode a particular downstream channel. In some cases, the UE may refract from monitoring POs until a WUS has been detected before a PO. Although the use of WUS can serve to optimize energy consumption in the UE, in some cases, the UE can lose the WUS and therefore also lose a subsequent alert message that includes important information regarding changes to the system information.
[006] [006] Consequently, a base station can set up an emergency mode for the UE to detect WUSs to avoid missed detection of alert messages. For example, a network can configure a UE to monitor POs regardless of the absence of a WUS to ensure that notifications regarding changes to system information are not lost. Such techniques can be referred to as WUS alert monitor frequency (or WUS alert monitoring frequency) and can allow the UE to monitor alert information according to a frequency configured by the network. For example, the base station or network can configure the UE to monitor alert information according to a periodicity related to PO periodicity, WUS periodicity, RRM measurement periodicity, or a modification period related to the modification of system information .

[0031] [0031] In a wireless communication system, a base station can signal that alert and / or system information is available on a channel for one or more user equipment (UEs). For example, the base station can send alerts or alert messages to a UE indicating that the information is available to the UE. In some cases, alert messages can lead to an indication of a change in system information (for example, a modification of a system information block (SIB)). In some instances, alert messages can be sent during alert occasions (POs) on a downlink control channel. The downlink control channel can be a physical downlink control channel (PDCCH) or a narrow band (NB) -PDCCH channel. POs can be periodic intervals configured for alert messages to allow UEs to enter a discontinuous receive or discontinuous receive (DRX) state between POs, and this process can be referred to as an alert inactive. In some examples, alert information can be sent over a shared physical downlink channel (PDSCH), which can be sent during the same transmission time interval (TTI) (for example, subframe) as the PDCCH or during a TTI different.
[0032] [0032] A base station can use a physical signal (for example, an activation signal (WUS)) to indicate that a UE should decode a subsequent physical downlink channel (for example, PDCCH or PDSCH) in the alert idle . WUS can also serve to optimize energy consumption in the UE. In some cases, the base station may introduce a periodic sync signal (SS) (for example, A primary SS (PSS), a secondary SS (SSS) and the like) in combination with the WUS to ensure sufficient synchronization performance . In other cases, the base station may refract transmission of the periodic SS With WUS or in a Discontinuous transmission mode (DTX).
[0033] [0033] In some cases, the network may change one or more information fields relevant to the system information. In addition, the network may transmit an alert message indicating that the system information has been modified. For example, the network can update an information field or element within the alert message pertaining to a change in the system information. Upon receiving an alert message that indicates a change in system information, the UE may attempt to monitor additional details regarding the change in system information. A UE capable of, and configured to detect, a WUS, can detect the WUS based on a WUS periodicity configured by higher layers.
[0034] [0034] In some cases, however, if the UE is configured to use the WUS for energy saving, the UE cannot read a downlink channel (for example, PDCCH / PDSCH) if a WUS is not detected. In some circumstances, the UE may lose a WUS, even if a WUS was transmitted for an alert message. For example, a large maximum loss of coupling (MCL) due to the size of a coverage area, frequency shift, time deviation, or intercellular interference with a neighboring base station can lead to a lost WUS. Additionally or alternatively, network errors, such as the repositioning of the base station, can lead to a change in the WUS configuration. For example, a base station may restart in a safe mode due to an electrical problem, causing a loss in WUS operation. If an UE is unable to detect the WUS correctly, the UE may miss important changes to the system information in alert information, causing consideration of the performance of the UE.
[0035] [0035] As described here, to alleviate the degradation of network performance and / or UE experienced with lost changes in system information, the network can configure a UE to monitor alert information periodically, even when a configured WUS is not detected . For example, the network can configure the UE with an alert monitoring periodicity to enable or trigger a UE to monitor the alert information. The configuration can be flagged explicitly (for example, through a SIB, a Radio Resource Control (RRC) setting, a higher layer parameter, or the like), implicitly flagged, or it can be determined based on pre-set parameters -configured. The configuration used to monitor the alert message can be referred to as a WUS alert monitor frequency, and can allow the UE to periodically monitor alert information according to a cycle configured by the network. For example, the base station or network can configure the UE to monitor alert information according to a cycle related to PO periodicity, WUS periodicity, radio resource measurement (RRM) periodicity, or modification period related to modification of system information.
[0036] [0036] aspects of the disclosure are initially described in the context of a wireless communications system. Aspects of the present invention are then described with reference to the timing diagrams. Aspects of the invention are further illustrated and described with reference to device diagrams, system diagrams and flow charts referring to an emergency mode for activation signal receivers.
[0037] [0037] Figure 1 illustrates an example of a wireless communication system 100 in accordance with various aspects of the present invention. The wireless communications system 100 includes base stations 105, UEs 115 and a central network 130. In some instances, the wireless communications system 100 may be a Long Term Evolution Network (LTE), an LTE-Advanced Network (LTE-A), or a New Radio (NR) network. In some cases, the wireless communications system 100 can support “improved broadband communications, ultra-reliable communications (for example, mission critical), low latency communications, or communications with low cost and low complexity devices.
[0038] [0038] Base stations 105 can communicate wirelessly with UEs 115 through one or more base station antennas. The base stations 105 described herein may include or may be referred to by those skilled in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an eNode B ( eNB), a next generation Node B or giga-nodeB (any of which may be referred to as gNB), a Domestic B node, a domestic eNodeB, or some other suitable terminology. Wireless communication system 100 can include base stations 105 of different types (for example, multiple or small cell base stations). The UEs 115 described here may be able to communicate with various types of base stations 105 and network equipment including macro eNBs, small cell eNBs, 9NBs, relay base stations, and the like.
[0039] [0039] Each base station 105 can be associated with a specific geographical coverage area 110 in which communications with multiple UEs 115 are supported. Each base station 105 can provide communication coverage for a respective geographic coverage area 110 through communication links 125, and communication links 125 between a base station 105 and a UE 115 can use one or more carriers. The communication links 125 shown on the wireless communication system 100 may include uplink transmissions from a UE 115 to a base station 105, or downlink transmissions, from a base station 105 to a UE 115. Transmissions from downlink can also be called direct link transmissions while uplink transmissions can also be called reverse link transmissions.
[0040] [0040] Geographic coverage area 110 for a base station 105 can be divided into sectors that make up only part of geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for a macro cell, a small cell, a hot spot, or other types of cells, or various combinations thereof. In some examples, a base station 105 can be mobile and therefore provide communication coverage for a mobile geographic coverage area
[0041] [0041] The term "cell" refers to a logical communication entity used to communicate with a base station 105 (for example, over a carrier), and can be associated with an identifier to distinguish neighboring cells (for example, a physical cell identifier (PCID), a virtual cell identifier (VCID) operating through the same carrier or a different carrier. In some instances, a vehicle can support multiple cells, and different cells can be configured according to different types of protocols (for example, machine-type communication (MTC), Narrow-of-Things (CABEL) Internet, enhanced mobile broadband (eMBB), or others) that can provide access to different types of devices. In some cases, the term "cell" may refer to a part of a geographic coverage area 110 (for example, a sector) through which the logical entity operates.
[0042] [0042] UEs 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. An UE 115 can also be referred to as a mobile device, a wireless device,
[0043] [0043] Some UEs 115, such as MTC or IoT devices, can be low-cost or low-complexity devices, and can provide automated communication between machines (for example, through machine-to-machine (M2M) communication) . M2M or MTC communication can refer to data communication technologies that allow devices to communicate with one another or a 105 base station without human intervention. In some examples, M2M or MTC communication may include communications from devices that integrate sensors or meters to measure or capture information and relay information to a central server or application program that can make use of the information or present information to humans interacting with the program or application. Some UEs 115 can be designed to collect information or allow automated machine behavior. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, health monitoring, lifetime monitoring, monitoring of meteorological and geological events, fleet management and tracking, remote security sensing , physical access control, and transaction-based commercial loading.
[0044] [0044] Some UEs 115 can be configured to employ modes of operation that reduce energy consumption, such as semi-duplex communications (for example, a mode that supports one-way communication through transmission or receiving, but not transmission and receiving simultaneously). In some instances, semi-duplex communications can be performed at a reduced peak rate. Other energy conservation techniques for UEs 115 include entering an energy-saving "deep sleep" mode when not engaging in active communications, or operating over a limited bandwidth (for example, according to communications narrowband). In some cases, UEs 115 can be designed to support critical functions (for example, mission critical functions), and a wireless communications system 100 can be configured to provide ultra-reliable communications for these functions.
[0045] [0045] In some cases, a UE 115 may also be able to communicate directly with other UEs 115 (for example, using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more of a group of UEs 115 using D2D communications may be within the geographical coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographical coverage area 110 of a base station 105, or they may otherwise be unable to receive transmissions from a base station 105. In some cases, groups of UEs 115 communicating via D2D communications may use a one to many (1: M) system in which each UE 115 transmits to each Other UE 115 in the group. In some cases, a base station 105 makes it easy to program resources for D2D communications. In other cases, D2D communications are carried out between UEs 115 without the involvement of a base station 105
[0046] [0046] The base stations 105 can communicate with the central network 130 and with each other. For example, base stations 105 can interface with central network 130 through backhaul links 132 (for example, through an SI or other interface). Base stations 105 can communicate with each other via backhaul links 134 (for example, via an X2 or other interface) either directly (for example, directly between base stations 105) or indirectly (for example, through core network 130).
[0047] [0047] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC), which can include at least one mobility management entity (MME), at least one service port (S-GW), and at least one Data port package (PDN) (P-GW). The MME can manage the non-access layer (for example, control plan functions) such as mobility, authentication and carrier management for UEs 115 served by base stations 105 associated with EPC. User IP packets can be transferred via s-GW, which can be connected to P-GW. P-GW can provide allocation of IP addresses as well as other functions. The P-GW can be connected to the IP services of network operators. Operator IP services may include Internet access, Intranet (s), An IP Multimedia Subsystem (IMS), or a Switched Packet (PS) streaming service.
[0048] [0048] At least some of the network devices, such as a base station 105, may include subcomponents such as an access network entity, which can be an example of an access node controller (ANC). Each access network entity can communicate with UEs 115 through several other access network transmission entities, which can be referred to as a radio head, an intelligent radio head, or a transmit / receive point ( TRP). In some configurations, various functions of each access network entity or base station 105 can be distributed across multiple network devices (for example, radio heads and access network controllers) or consolidated into a single network device ( for example, a base station 105).
[0049] [0049] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The 300 MHz to 3 GHz region is generally known as the ultra-high frequency (UHF) region or decibel band, as wavelengths range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features. However, waves can penetrate the structures sufficiently for a macro cell to provide service to UEsS 115 located indoors. The transmission of UHF waves can be associated with smaller antennas and shorter bands (for example, less than 100 km) compared to transmission using the lower frequencies and longer waves of the high frequency (HF) or very frequency spectrum (VHF) of the spectrum below 300 MHz.
[0050] [0050] The wireless communication system 100 can also operate in a high frequency region (SHF) using frequency bands from 3 GHz to 30 GHz, also known as the centimeter band. The SHF region includes bands such as 5 GHz industrial, scientific and medical (ISM) bands, which can be used in a timely manner by devices that can tolerate interference from other users.
[0051] [0051] The wireless communications system 100 can also operate in an extremely high frequency (EHF) region of the spectrum (for example, from 30 GHz to 300 GHz), also known as the millimeter band. In some examples, wireless communication system 100 can support millimeter wave (mmW) communications between UEs 115 and base stations 105 and the EHF antennas of the respective devices can be even smaller and more closely spaced than UHF antennas. . In some cases, this can facilitate the use of antenna sets within an UE 115. However, the spread of EHF Transmissions can be subjected to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The techniques described here can be employed through transmissions that use one or more regions of different frequency, and the designated use of bands across these frequency regions may differ by country or body of regulation.
[0052] [0052] In some cases, the wireless communication system 100 may use licensed and unlicensed radio frequency spectrum bands. For example, wireless communications system 100 may employ License Assisted Access (LAA), LTE-unlicensed radio access Technology (LTE-U), or R Technology in an unlicensed band such as the ISM band of 5 GHz. When operating in unlicensed radio frequency spectrum bands, wireless devices such as base stations 105 and UEs 115 may employ listening before speaking (LBT) procedures to ensure that a frequency channel is clear before transmit data. In some cases, operations on unlicensed bands may be based on a CA configuration in conjunction with CCs that operate on a licensed band (for example, LAA). Operations on the unlicensed spectrum may include downlink transmissions, upper link transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum can be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of both.
[0053] [0053] In some examples, the base station 105 or UE 115 can be equipped with multiple antennas, which can be used to employ techniques such as diversity of transmission, diversity of reception, communications of multiple inputs and multiple outputs (MIMO), or beam formation.
[0054] [0054] Beam formation, which can also be referred to as spatial filtering, directional transmission, or directional receiving, is a signal processing technique that can be used on a transmitting device or a receiving device (for example, a base 105 or UE 115) to form or direct a beam of antennas (for example, a transmit beam or receive beam) along a space path between the transmitting device and the receiving device. Beam formation can be achieved by combining the signals communicated through antenna elements of a set of antennas, so that signals that propagate in particular orientations with respect to a set of antennas experience constructive interference, while others experience destructive interference . The adjustment of the signals communicated through the antenna elements can include a transmitting device or a receiving device that applies certain amplitude and phase deviations to signals conducted through each of the antenna elements associated with the device. The settings associated with each of the antenna elements can be defined by a beamform weighting set associated with a particular orientation (for example, with respect to the set of antennas of the transmitting or receiving device, or with respect to some other guidance).
[0055] [0055] In one example, a base station 105 can use multiple antennas or antenna arrays to conduct beamform operations for directional communications with a UE 115. For example, some signals (for example, synchronization signals, reference, beam selection signals, or other control signals can be transmitted by a base station 105 multiple times in different directions, which can include a signal that is transmitted according to different sets of beamforming weights associated with different transmission directions.
[0056] [0056] A receiving device (for example, a UE 115, which can be an example of a mmW receiving device) can attempt multiple receiving beams when receiving various signals from base station 105, such as synchronization signals, reference signals , beam selection signals, or other control signals. For example, a receiving device may attempt multiple receiving directions by receiving through different antenna arrays, by processing signals received according to different antenna subarrays, receiving according to different receiving beamform weighting sets applied to signals received on a plurality of antenna elements of an antenna array, or by processing received signals according to different sets of receiving beamforming weights applied to signals received on a plurality of antenna elements of a set of antennas , any of which may be referred to as "hearing" according to different receiving beams or receiving directions. In some examples, a receiving device may use a single receiving beam to receive along a single beam direction (for example, when receiving a data signal). The single receiving beam can be aligned in a given beam direction based at least in part on hearing according to different receiving beam directions (for example, a beam direction determined to have a higher signal strength, higher signal-to-noise ratio, or otherwise acceptable signal quality based on at least partly in hearing according to multiple beam directions).
[0057] [0057] In some cases, the antennas of a base station 105 or UE 115 may be located within one or more sets of antennas, which can support MIMO operations, or transmit or receive beam formation. For example, one or more base station antennas or antenna arrays can be colocalized in an antenna array, such as an antenna tower. In some cases, antennas or antenna sets associated with a base station 105 may be located in several geographic locations. The base station 105 can have a set of antennas with multiple rows and columns of antenna ports that the base station 105 can use to support the formation of communications beam with a UE 115. Likewise, a UE 115 can have one or more sets of antennas that can support various MIMO or beamforming operations.
[0058] [0058] In some cases, wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. At the user level, communications on the carrier or packet Data Convergence Protocol (PDCP) layer can be IP based. A Radio Link Control (RLC) layer can, in some cases, perform segmentation and reassembly of packets to communicate through logical channels. A Medium Access Control (MAC) layer can perform priority handling and multiplexing of logical channels in transport channels. The MAC layer can also use hybrid automatic retry request (HARQ) to provide retransmission at the MAC layer to improve binding efficiency. In the control plane, the Radio Resource control protocol (RRC) layer can provide for establishing, configuring and maintaining an RRC connection between an UE 115 and a base station 105 or core network 130 supporting radio bearers for user plan data. In the physical layer (PHY), transport channels can be mapped to physical channels.
[0059] [0059] In some cases, UEs 115 and base stations 105 can support data retransmissions to increase the likelihood that data will be received successfully. HARQ feedback is a technique to increase the likelihood that data will be received correctly over a communication link 125. HARQ may include a combination of error detection (for example, using a cyclic redundancy check (CRC), early correction errors (FEC) and retransmission (for example, automatic retry request (ARQ)). HARQ can improve transmission capacity at the MAC layer in poor radio conditions (for example, signal to noise conditions). In some cases , a wireless device can support HARQ feedback from the same partition, where the device can provide HARQ feedback on a specific partition for data received on a previous symbol on the partition. In other cases, the device can provide HARQ feedback on a subsequent partition, or according to some other time interval.
[0060] [0060] Time intervals in LTE or NR can be expressed in multiples of a basic time unit, which can, for example, refer to a sampling period of Ts = 1 / 30,720,000 seconds. The time intervals of a communications resource can be organized according to radio frames, each having a duration of 10 milliseconds (ms), where the frame period can be expressed as Tf = 307,200 Ts. Radio frames can be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame can include 10 subframes numbered 0 to 9, and each subframe can have a duration of 1 ms. a subframe can be further divided into 2 partitions each having a duration of 0.5 ms, and each partition can contain 6 or 7 periods of modulation symbols (for example, depending on the length of the cyclic prefix prepended to each symbol period). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe may be the smallest programming unit of the wireless communications system 100, and may be referred to as a transmission time interval (TTI). In other cases, the smallest programming unit of the wireless communications system 100 may be shorter than a subframe or may be dynamically selected (for example, in bursts of Shortened TTIs (sTTIS) or in selected component carriers using sTTIs).
[0061] [0061] In some wireless communication systems, a partition can be further divided into multiple mini-partitions containing one or more symbols. In some cases, a mini-partition or mini-partition symbol may be the smallest programming unit. Each symbol can vary in duration depending on the sub-carrier spacing or operating frequency band, for example. In addition, some wireless communications systems may implement partition aggregation in which multiple partitions or mini-partitions are aggregated and used for communication between an UE 115 and a base station 105.
[0062] [0062] The term "bearer" refers to a set of radio frequency spectrum resources having a physical layer structure defined to support communications over a communication link 125. For example, a bearer of a communication link 125 may include a portion of a radio frequency spectrum band that is operated according to physical layer channels for a given radio access technology. Each physical layer channel can carry user data, control information, or other signaling. A carrier can be associated with a predefined frequency channel (for example, an e-UTRA absolute radio frequency channel number (EARFCN)), and can be positioned according to a channel scan for discovery by the UEs
[0063] [0063] The organizational structure of carriers may be different for different radio access technologies (for example, LTE, LTE-A, NR, etc.). For example, communications about a vehicle can be organized according to TTIS or slots, each of which can include user data as well as control or signaling information to support the decoding of user data. A carrier can also include dedicated pickup signaling (for example, synchronization signals or system information, etc.) and control signaling that coordinates the operation for the carrier. In some examples (for example, in a carrier aggregation configuration), a carrier may also have capture signaling or control signaling that coordinates operations for other carriers.
[0064] [0064] the physical channels can be multiplexed in a vehicle according to various techniques. A physical control channel and a physical data channel can be multiplexed on a downlink carrier, for example, using time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or TDM techniques -FDM hybrids. In some examples, control information transmitted on a physical control channel can be distributed between different control regions in a cascading manner (for example, between a common control region or common search space and one or more control regions specific EU or EU specific search spaces).
[0065] [0065] A carrier can be associated with a particular bandwidth of the radio frequency spectrum, and in some instances the carrier bandwidth can be referred to as a "system bandwidth" of the carrier or wireless communications system 100. For example, carrier bandwidth can be one of several predetermined bandwidths for carriers of a specific radio access technology (for example, 1,4, 3, 5, 10, 15, 20, 40 or 80 MHz). In some instances, each served UE 115 may be configured to operate over parts or all of the carrier's bandwidth. In other examples, some UEs 115 can be configured for operation using a type of narrowband protocol that is associated with a predefined portion or range (for example, set of subcarriers or RBs) within a carrier (for example, split "on bandwidth "of a type of narrowband protocol).
[0066] [0066] In a system employing MCM techniques, a feature element can include a symbol period (for example, a modulation symbol duration) and a subcarrier, where the symbol period and the sub-carrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (for example, the order of the modulation scheme). Thus, the more resource elements that an UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for the UE 115. In MIMO Systems, a wireless communications resource can refer to a combination of a radio frequency spectrum resource, a time resource and a space resource (for example, space layers), and the use of multiple space layers can further increase the data rate for communications with a UE
[0067] [0067] Wireless communications system devices 100 (e.g., base stations 105 or UEs 115) may have a hardware configuration that supports communications over a specific carrier bandwidth, or may be configurable to support communications over of one of a set of carrier bandwidths. In some examples, wireless communications system 100 may include base stations 105 and / or UEs that can support simultaneous communications through carriers associated with more than a different carrier bandwidth.
[0068] [0068] The wireless communication system 100 can support communication with a UE 115 in multiple cells or carriers, a feature that can be referred to as a carrier aggregation (CA) or multi-carrier operation. A UE 115 can be configured with multiple downlink CCs and one or more uplink CCs according to a carrier aggregation configuration. Carrier aggregation can be used with both FDD and TDD component carriers.
[0069] [0069] In some cases, the wireless communications system 100 may use enhanced component carriers (eCCs). An ecc can be characterized by one or more features including wider frequency or carrier channel bandwidth, shorter symbol duration, shorter TTI duration, or modified control channel configuration. In some cases, an eCC can be associated with a carrier aggregation configuration or a dual connectivity configuration (for example, when multiple service cells have a sub-optimal or not ideal backhaul link. An eCC can also be configured for use in unlicensed spectrum or shared spectrum (for example, where more than one operator is allowed to use the spectrum.) An eCC characterized by broad carrier bandwidth can include one or more segments that can be used by UEs 115 that are not capable of monitoring the entire carrier bandwidth or are otherwise configured to use limited carrier bandwidth (for example, to conserve energy).
[0070] [0070] In some cases, an eCC may use a different symbol duration than other CCs, which may include the use of a reduced symbol duration compared to symbol durations of the other CCs. A shorter symbol life can be associated with greater spacing between adjacent subcarriers. A device, such as an UE 115 or base station 105, using eCCs, can transmit broadband signals (for example, according to channel, bandwidth or carrier frequency bandwidths of 20, 40, 60, 80 MHz, etc. .) in reduced symbol durations (for example, 16.67 microseconds). An eCC TTI can include one or multiple symbol periods. In some cases, the duration of the TTI (that is, the number of symbol periods in a TTI) can be variable.
[0071] [0071] Wireless communications systems, such as the R system, can use any combination of licensed, shared and unlicensed spectrum bands, among others. The flexibility of eCC symbol duration and sub-carrier spacing can allow the use of eCC across multiple spectra. In some instances, the shared NR spectrum can increase spectrum utilization and spectral efficiency, specifically through vertical (eg, through frequency) and horizontal (eg, over time) resource sharing.
[0072] [0072] In some cases, an UE 115 can monitor a communication link 125 continuously for an indication that the UE 115 can receive data. In other cases (for example, to conserve energy and extend battery life) an UE 115 can be configured with a batch receiving cycle (DRX). A DRX cycle can include a "duration" when the UE 115 can monitor control information (for example, in PDCCH) and a "DRX period" when the UE 115 can energize radio components. In some cases, an UE 115 can be configured with a short DRX cycle and a long DRX cycle. In some cases, an UE 115 may introduce a long DRX cycle if it is inactive for one or more short DRX cycles. The transition between the short DRX cycle, the long DRX cycle and continuous reception can be controlled by an internal timer or by exchanging messages from a base station
[0073] [0073] In wireless communication system 100, a base station 105 can signal a change in system information to a UE 115 via an alert or alert message. The alert message can lead to an indication of the change in system information and can also indicate that the alert information is available for one or more UEs 115 associated with base station 105. A UE 115 can periodically monitor alert messages transmitted to from the base station during POs. A PO can be a TTI where a downlink channel such as A PDCCH or PDSCH addresses the alert message. A base station 105 in the wireless communication system 100 can use a WUS during the alert idle to indicate whether the UE 115 needs to decode a specific physical downlink channel to determine if there is a change in the system information. In some cases, the UE 115 may refract from monitoring POs until a WUS has been detected before a PO. To ensure that notifications regarding changes to system information are not lost (for example, if a transmitted WUS is not received), the network can configure a UE 115 to monitor POs regardless of the absence of a WUS. A non-WUS alert monitor periodicity can be configured and can allow the UE 115 to periodically monitor alert information according to a cycle configured by the network. For example, base station 105 or network can configure UE 115 to monitor alert information according to a cycle related to PO periodicity, WUS periodicity, RRM measurement periodicity, or a modification period related to information modification of system.
[0074] [0074] Figure 2 illustrates an example of a wireless communication system 200 that supports an RRM configuration for UEs with WUS receivers in accordance with various aspects of the present invention. In some examples, the wireless communications system 200 may implement aspects of the wireless communications system
[0075] [0075] In wireless communication system 200, base station 105-a can send alerts or alert messages 205 to one or more UEs 115, including UE l15-a, to indicate what information (such as data in the downlink) or other information) are available for one or more of the UEs 115. In some cases, alert messages 205 may also carry an indication of a change in system information (for example, in a SIB). Alert messages 205 can be sent using POs from a downlink control channel, where the downlink control channel can be a PDCCH or a B-PDCCH. POs can be periodic intervals configured for alert messages 205 to allow UE 115-a to enter a waiting state or DRX between POs, and this process can be referred to as alert inactive. In some examples, alert information can be sent in A PDSCH, which can be sent during the same TTI as a PDCCH or during a different TTI than PDCCH.
[0076] [0076] In some cases, the base station 105- a may use a physical power saving signal (for example, WUS 210) to indicate whether the UE 115-a should decode a subsequent physical downlink channel (for example, PDCCH or PDSCH) on idle alert. In some cases, the WUS 210 can serve to optimize energy consumption in the UE 115-a, for example, where the UE 115-a can rely on receiving WUS 210 before waking from a sleep state. In some cases, the base station 105-a may introduce periodic synchronization signals (for example, PSS or SSS) in combination with WUS 210 (and / or with
[0077] [0077] In some cases, the network or base station 105-a can change one or more fields of information belonging to a SIB. In such cases, base station 105-a may proceed to transmit the Modified SIB, as well as another SIB (for example, SIBl) with an updated field (for example, systemInfoValueTag). In addition, base station 105-a can transmit alert message 205 with an indication that the system information has been modified. For example, base station 105-a can update an information field or element within alert message 205 pertaining to a change in system information (for example, systemInfoModification). In some cases, the field can comprise a Boolean value and can, for example, be set to "true" (for example, using Boolean logic With a bit value of "* 1 ').
[0078] [0078] When receiving the alert message 205 that indicates a change in system information (for example, systemInfoModification = true), UE 115-a may attempt to monitor SIBl for additional details relevant to the change in system information. For example, the systemInfoValueTag value tag transmitted within SIBl may change during a period of modification, and may provide an indication of the change in system information. In some cases, the modification period can be specified in another block of system information (for example,
[0079] [0079] In some cases, UE 115-a may be able to and configured to detect WUS 210, and can thus detect WUS 210 based on a WUS Periodicity configured by higher layers. Thus, if the UE 115-a is configured to detect WUS 210 for energy savings, UE l115-a may not read a channel on the downlink, such as O PDCCH or PDSCH, if WUS 210 is not detected. In some circumstances, however, UE 115-a may lose WUS 210 even if WUS 210 were transmitted to alert message 205. For example, a Large MMCL due to a relatively large footprint, frequency deviation, time drift, or intercellular interference with a neighboring base station 105 (not shown) or other device can lead to a lost WUS 210. In some cases, network errors or a repositioning at base station 105-a (for example, due to a power failure) may lead to a change in the WUS configuration. For example, base station 105-a may restart in safe mode due to an electrical problem, causing a loss in WUS operation. As a result, if the UE 115-a is unable to detect the WUS 210 correctly, the UE 115-a may miss important changes in the system information carried “by the alert information within the 205 alert message, which can affect the performance of the EU 115-a.
[0080] [0080] To alleviate the impact of the network and / or the UE due to lost changes in the system information, the base station 105-a can configure the UE 115-a to monitor the alert information periodically. That is, even when the WUS 210 is lost by (for example, not received) The UE 115-a, the UE 115-a can monitor the alert information sent from the base station 105-a, for example, the base 105-a can configure UE 115-a with a "WUS-free alert monitoring periodicity" to enable or trigger UE 115-a to monitor alert information outside the receipt of WUSs. In some cases, the configuration can be signaled explicitly (for example, via SIB, RRC or via an upper layer parameter). For example, the alert time window (PTW) and DRX parameters can be negotiated through Non-Access layer (NAS) signaling messages, and the alert monitoring periodicity setting can be indicated via such NAS Signaling. . In other cases, the base station 105-a can use a predefined parameter to configure the UE l15-a with the alert monitoring periodicity without WUS. For example, base station 105-a can establish a maximum time interval during which UE l15-a can skip WUS 210 monitoring at least once. The hop monitoring WUS 210 can correspond to the monitoring of alert information in the absence of WUS 210. In some cases, the configuration can be signaled implicitly, for example, declaring a relationship between the 'alert monitoring periodicity without WUS " and another parameter, such as a DRX cycle.
[0081] [0081] As described here, these techniques may allow an emergency mode for UE l115-a when configured to operate using WUSs 210 to periodically monitor alert message 205. In such cases, the periodicity by which UE l115-a awakens to alert message 205 can be dynamically configured, allowing different levels of protection against WUS 210 lost / failed reception. For example, base station 105-a can configure alert monitoring frequency based on channel conditions or interference experienced within a cell. Consequently, the “alert monitoring periodicity can be configured for UE l115-a to wake up more or less based at least in part on the dynamic configuration of the alert monitoring periodicity.
[0082] [0082] In some examples, the use of emergency mode can allow efficient communications when the UE 11115-a is mobile. For example, UE 115-a may be traveling between different cells. The respective cells can each support the use of WUSs, and the UE 115-a may have information associated with WUSs Used by a neighboring cell (for example, a cell that previously served the UE 115-a before the UE l115- a moved to a cell provided by base station 105-a). When moving to the cell provided by base station 105-a, UE 115-a may not immediately have information (for example, a configuration) associated with a WUS 210 transmitted by base station 105-a As such, use emergency mode, where UE 115-a can activate to obtain alert information from base station 105-a without receiving WUS 210 (for example, based on an alert monitoring periodicity), can allow Let UE 115-a obtain alert information (and system information indicated by alert messages) from base station 105-a. The UE 115-a can thus skip the detection of WUS 210 and can detect alert messages directly, where the use of such techniques can be based on the UE 115-a moving between cells.
[0083] [0083] Figure 3 illustrates an example of a timing diagram 300 in a system that supports an RRM configuration for UEs with WUS receivers in accordance with various aspects of the present invention. In some examples, timing diagram 300 can implement aspects of wireless communication system 100 and / or 200.0 Timing diagram 300 shows an example of how a UE 115 can use an activation periodicity to alert inactive while employing a periodicity alert monitoring system without WUS.
[0084] [0084] Timing diagram 300 can illustrate a representation of what occurs in the PHY layer for a UE 115 configured with a WUS alert monitoring periodicity over a network. In a first scheme of developing an alert monitoring without WUS, the network can configure a UE 115 to periodically detect (for example, each X POs or X DRXs) a downlink channel (for example, PDCCH or PDSCH) comprising information from alert 320, where each DRX Cycle can Include a PO. As illustrated in timing diagram 300, WUS occasions 303 can represent occasions during which a base station 105 can transmit a WUS, which can be detected by UE 115. Additionally, the time period between POs can be represented by the periodicity of PO 305, and the alert monitoring periodicity 310 denotes the alert monitoring periodicity without WUS having a * DRX periodicity. In the example illustrated in timing diagram 300, X = 4. However, X can be any integer, where X 2 1.
[0085] [0085] In some cases, a WUS 315 (for example, WUS 315-a) can inform the UE 115 to monitor a PO in a DRX cycle. For example, if X = 1, a UE 115 can return to a mode and assume that no WUS 315 is enabled. In such cases, the UE 115 can monitor for a downlink channel (PDCCH / PDSCH) at each PO. In other cases, if X> 1 (for example, X = 8, X = 16, etc.), the frequency of alert monitoring without WUS can be set to "X * DRX" In such cases, the UE 115 can monitor a downlink channel for alert information 320 for each X DRXs or X POs, regardless of the presence or detection of WUS 315. In some cases, as illustrated in timing diagram 300, a UE 115 configured with the DRX frequency may lose the WUS 325. The UE 115, however, can still proceed to detect the alert information 320-a due to being configured with the 310 monitoring alert periodicity. That is, regardless of the lost WUS 325, the UE 115 can proceed to activation from a waiting state to receive alert information 320-a.
[0086] [0086] Figure 4 illustrates an example of a timing diagram 400 in a system that supports an RRM configuration for UEs with WUS receivers According to various aspects of the present invention. In some examples, timing diagram 400 can implement aspects of the wireless communication system 100 and / or 200.0 Timing diagram 400 shows an example of how an idle wake-up cycle can operate while employing a monitoring periodicity alert without WUS. Timing diagram 400 can illustrate a representation of what occurs in the PHY layer for a UE 115 configured with WUS-free alert monitoring periodicity over the network. In the example illustrated by timing diagram 400, a network can configure a UE 115 to detect a downlink channel for alerting information on every Y WUS occasions, where Y 2 1. Unlike the example described with reference to Figure 3, the granularity The detection of alert information in this example can be based on WUS, not PO.
[0087] [0087] In some cases, the WUS 403 occasions may represent occasions during which a base station 105 can transmit a WUS 415, which can be detected by the UE 115. However, as illustrated in timing diagram 400, a WUS 415 ( for example, at the time WUS 403-a) can inform the UE 115 to monitor a PO or multiple POs within a PTW in an extended DRX cycle (eDRX) (for example, there may be a WUS 415 every Y POs, where Y 2 1). The WUS 405 periodicity can be equal to * PO (or * DRX) periodicity. In some cases, if Y = 1, the UE 115 can return to a particular mode and assume that no WUS 415 is enabled. In such cases, the UE 115 can monitor alert information 420 at one or more POs within a PTW in the eDRX cycle. As illustrated, the time period when WUSs 415 can be transmitted can be represented by the WUS 405 periodicity, and the “alert monitoring 410 periodicity can represent an alert monitoring periodicity without WUS, which can have an alert monitoring periodicity 410 equal to the WUS 405 periodicity. That is, in the cases where Y> 1 (for example, Y = 4.8, l16, etc.), the alert monitoring periodicity without WUS can be adjusted to the WUS 405 periodicity. The UE 115 can monitor the downlink channel (s) for alert information 420 independently of Detecting a WUS 415 to reduce the likelihood of missed changes to system information or other information that may affect the communications efficiency of the UE 115. For example, as shown in timing diagram 400, a UE 115 configured with an alert monitoring periodicity 410, the UE 115 may still detect alert information 420-a due to being configured. figured with the frequency of Alert Monitoring without WUS.
[0088] [0088] Figure 5 illustrates an example of a timing diagram 500 in a system that supports an RRM configuration for UEs with WUS receivers According to various aspects of the present invention. In some examples, timing diagram 500 may implement aspects of the wireless communication system 100 and / or 200.
[0089] [0089] In a third WUS alert monitoring development scheme, a network can configure a UE 115 to detect downlink channels for alerting each M RRM measurement periods, where M 2 1. For example, in some cases, an RRM measurement can include the measurement of an RSRP, an RSRQ, confirming a service cell or connection cell, etc. In some examples, measurements may indicate a mobility condition of the UE 115 (for example, a low mobility UE 115). (As illustrated in timing diagram 500, WUS 503 occasions can represent occasions when a base station 105 can transmit a WUS 515, which can be detected by a UE 115. In some cases, the UE 115 may not perform Measurements RRM in each DRX cycle, enabling power savings in the UE 115.
[0090] [0090] In addition, RRM measurements can be performed according to the RRM 505 measurement frequency Configured by the network. That is, the network can determine whether an UE 115 can use an RRM 505 measurement periodicity that has a certain duration, and for example, the network can configure the RRM 505 measurement periodicity based on the RRM Measurements performed by an UE 115. For example, previous RRM measurements performed by the UE 115 (For example, for a server cell) may vary within a predetermined limit, and a base station 105 may indicate a longer RRM measurement periodicity 505 configured for the UE 115 (For example, based on variation). In some cases, RRM measurements may be based on synchronization signals (for example, PSS, SSS, Resync SS for eMTC, narrowband PSS (NPSS) or narrowband SsSSs (NSSS) for NB-IoT), Reference (for example, cell-specific reference signal (CRS), narrow-band reference signal (RS) For NB-IOoT), or a combination thereof.
[0091] [0091] In some cases, if M = 1, the UE 115 can monitor a notification pertaining to a change in the system information indicated by the alert at least once for each RRM measurement period. In other cases, if M> 1 (for example, M = 4,8,16, etc.), an alert monitoring periodicity without WUS can be adjusted to the RRM 505 measurement periodicity, as shown by the monitoring periodicity alert 510. Thus, the UE 115 can monitor alert information 520 every M RRM measurement periods, regardless of whether a WUS is detected or not. For example, as shown in the timing diagram 500, an UE 115 configured with an alert monitoring periodicity 510 equivalent to the measurement periodicity 505 M * RRM can lose the WUS 525. However, the UE 115 can still proceed to detect the alert 520-a due to being configured with a non-WUS Alert Monitoring periodicity.
[0092] [0092] In some cases, a UE 115 may include different receivers (for example, receiver chains, antennas, antenna arrays, etc.) for the detection of a WUS and the performance of RRM measurements. For example, the UE 115 can use a first receiver to monitor the alert and make RRM measurements, while the UE 115 can use a second receiver (for example, having a lower power than the first receiver) to detect a WUS. Thus, when the UE 115 switches on the first receiver to perform RRM measurements, the UE 115 can detect the alert while the receiver is still on. Such techniques can also serve to optimize energy consumption in the UE 115, where the UE 115 can refract from waking up on additional occasions, and can instead detect warning information while performing RRM measurements.
[0093] [0093] In some cases, the UE 115 can perform RRM measurements before each WUS moment. In such cases, RRM measurements can be modified or relaxed to further optimize energy consumption in the UE 115. For example, to perform RRM measurements before receiving a WUS, the UE 115 can synchronize (for example, using a received WUS ) or wake up the Receiver associated with RRM measurements (for example, the first receiver) in addition to monitoring the WUS. In some cases, the UE 115 may limit the performance of RRM measurements to use its receiving resources efficiently. For example, the UE 115 can perform RRM measurements once every P DRX Cycles, where P can be an integer greater than l. In such cases, RRM measurements can be performed less frequently (for example, compared to performing RRM measurements during each DRX cycle), thus allowing the UE 115 to remain in an energy saving mode for a longer period of time. long. Additionally or alternatively, when RRM measurements have a relaxed frequency (for example, using Less Frequent RRM measurement occasions), a UE 115 can use the WUS received during an RRM Measurement period to synchronize with a 105 base station. In such cases, the WUS can be configured for each DRX cycle, but the UE 115 can only wake up all P DRX cycles, when the WUS can be detected.
[0094] [0094] In some cases, the UE 115 can perform RRM measurements once every R = X POs = X WUS Occasions, where each PO can be configured with a WUS. In some other cases, the UE 115 can perform RRM measurements once every R = Y WUS occasions, if POs are configured with more than one WUS, for example, in eDRX, as described in the development schemes above. In some cases, if there is a WUS detected within the R WUS Occasions, the UE 115 can perform RRM Measurements and monitor the alert after the detection of a WUS. In other examples, if no WUS is detected at the time of R WUS, the UE 115 can perform RRM measurements at the time of Room Temperature.
[0095] [0095] Figure 6 illustrates an example of a timing diagram 600 in a system that supports an RRM configuration for UEs with WUS receivers According to various aspects of the present invention. In some examples, timing diagram 600 may implement aspects of wireless communication system 100 and / or 2002. Timing diagram 600 may illustrate the modification periods employed in some wireless communication systems, which are used to notify a EU 115 of a change in system information.
[0096] [0096] In some cases, the change in system information may occur during specific radio frames, and the same system information may be transmitted within a period of modification. As shown in timing diagram 600, different shading patterns indicate different system information. In addition, the 605-a modification period (for example, a broadcasting control channel (BCCH) modification period) denotes the change notification time period (or modification period (n)), while the modification period 605-b (for example, another modification period of
[0097] [0097] In a fourth scheme of development of alert monitoring periodicity without WUS, the network can configure a UE 115 to monitor a notification pertaining to changes in the system information in alert and / or SIB 1 (or MIB) every N Modification periods, where N 2 1. For example, similar to the deployment schemes described above, if N = 1, the UE 115 can monitor a notification related to the change of system information in an alert message, SIB 1 or MIB, or a combination thereof, during each 605 modification period. Information pertaining to the 605 modification period may be received at another SIB, such as SIB2. In some other cases, if N> l, the alert monitoring periodicity without WUS can be established in the modification period N * 605-b, as illustrated by the alert monitoring periodicity 610. Thus, the UE 115 can monitor the alert a Every N Modification periods 605. Additionally, N can be different based on the type of radio technology employed in the UE 115 (for example, eMTC, NB-IoT, etc.).
[0098] [0098] In some cases, the UE 115 can decide autonomously when one or more RRM measurements are made Within the occasions of R WUS, as described with reference to figure 5 in an alternative scheme for conducting RRM measurements in conjunction with the detection From WUS, the UE 115 can perform RRM measurements when configured by the base station or base to read downlink channels such as PDCCH or PDSCH Bearing alert information, regardless of the presence or detection of WUS (that is, according to the periodicity alert monitor configured 610 without WUS). For example, if the 610 alert monitor periodicity can be configured as N * modification period, the UE 115 can perform RRM measurements as well as cell confirmation (that is, for the server cell or the encamped cell) when there is a potential change in system information, regardless of the detection of a WUS.
[0099] [0099] Figure 7 illustrates an example of a process flow 700 that supports an RRM configuration for UEs with WUS receivers According to various aspects of the present invention. In some examples, process flow 700 can implement aspects of the wireless communication system 100 and / or 200. In addition, process flow 700 can be implemented by an UE 115-b and a base station 105-b, which can be examples of an UE 115 and a base station 105 as described with reference to Figures 1 and 2. In some examples, the process illustrated by process flow 700 can be implemented in a wireless R system, and can support the use of an alert monitoring periodicity for the efficient detection of alert messages by a UE 115.
[00100] [00100] At 705, base station 105-b can determine an alert monitoring frequency (for example, "alert monitoring frequency without WUS") to configure UE 115-b to monitor an alert message. In some wireless communication systems, WUSs can be implemented as energy saving signals, enabling an UE to remain in idle mode until a PO alert message indicates a change in system information, or alert information for the HUH. In 710, base station 105-b can thus determine a WUS periodicity for a plurality of WUSs, where the WUS periodicity can be less than or equal to the alert monitoring periodicity.
[00101] [00101] In 715, the base station 105-b can transmit, and the UE 115-b can receive, an alert monitoring periodicity setting. In some instances, the alert monitoring configuration can optionally indicate a relationship between the alert monitoring frequency determined in 705, and the WUS frequency determined in 710. In some cases, the base station 105-b can transmit, within the configuration, an indication that the alert monitoring periodicity comprises one or more POs, or an indication that the alert monitoring periodicity comprises one or more WUS occasions, or an indication that the alert monitoring periodicity comprises one or more more RRM measurement periods, or a combination of them. In some cases, the configuration may also provide an indication that the alert monitoring periodicity comprises one or more BCCH modification periods. The configuration can be transmitted via a system information message, an RRC message, or a NAS message.
[00102] [00102] In 720, UE 115-b can determine the frequency of alert monitoring, for example, based on the received configuration. For example, UE 115-b may determine that the alert monitoring periodicity includes one or more POs based on the configuration (for example, the alert monitoring periodicity is the DRX periodicity, as described above with reference to Figure 3) , where A WUS periodicity can also correspond to one or more POs. In such cases, the configuration can cover both DRX (where there is only one PO) and eDRX (where there are one or more POs determined by PTW). For example, UE 115-b may determine that the alert monitoring periodicity includes one or more WUS occasions based on the configuration, where the WUS periodicity corresponds to a PTW periodicity that includes one or more POs (for example, the monitoring periodicity alert is the periodicity X * WUS, as described above with reference to Figure 4).
[00103] [00103] In some examples, UE 115-b may determine that the alert monitoring periodicity comprises one or more RRM measurement periods based on the configuration (for example, the alert monitoring periodicity is the RRM measurement periodicity, as described above with reference to figure 5). Additionally or alternatively, UE 115-b may determine that the alert monitoring periodicity comprises one or more BCCH modification periods based on the configuration (for example, as described with reference to Figure 6).
[00104] [00104] In 725, UE 115-b can proceed to carry out discontinuous monitoring for a plurality of WUSs based on the WUS periodicity, and monitor alert messages during an alert monitoring period according to the periodicity monitoring alert, or the WUS periodicity, or a Received WUS based on the WUS periodicity, or a combination thereof. For example, UE 115-b can monitor the alert message according to the PO periodicity and the received WUS. In other cases, the UE 115-b can monitor the alert message according to the PTW frequency and the received WUS. Additionally or alternatively, the UE 115-b can monitor the alert message according to one or more POs and the WUS received. In some cases, the UE 115-b can monitor the alert message according to an RRM measurement periodicity, or it can monitor, according to a BCCH modification period, for the alert message, or a SIB, or a MIB, or a combination thereof.
