AI Technical Summary
The lack of sequence or priority indication when measuring frequency bands by user equipment (UE) leads to the reporting of lower quality frequency bands, which affects network performance and throughput.
The UE prioritizes frequency bands based on parameters received from the base station and sends a measurement report after a time delay to ensure that the measurement thresholds of the network and the UE are met.
Through priority sorting and delayed transmission mechanisms, UEs can identify and report high-quality frequency bands, avoiding the addition of low-quality cells and improving network performance and throughput.

These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (e.g., Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems).

A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)).
[0005] The UE can measure frequency bands and send a measurement report of the frequency bands to the base station. However, the UE may not measure the frequency bands in any order, which may result in reports of lower quality frequency bands. Summary of the Invention

[0047] A User Equipment (UE) can operate in a wireless communication system and communicate with network devices such as base stations. A UE can measure multiple objects (such as different frequency bands) to determine factors such as channel quality for each band. For example, a UE can measure multiple different Absolute Radio Channel Numbers (ARFCNs). In some cases, the UE may receive an indication of the multiple objects (e.g., frequency bands) for the UE to measure. In some cases, this indication may not include an indication of the order in which the UE can measure the frequency bands. Without any indication of order or priority, the UE may measure each frequency band in the order in which they are received or in another order, without prioritizing the measurements of the frequency bands.
[0048] For example, in some systems (e.g., fourth-generation (4G) systems, such as Long Term Evolution (LTE) systems), the UE can configure the gaps for each measurement object in the same order as the network configures each measurement object (e.g., in the order in which the measurement object or frequency band is received). The UE can measure each frequency band based on the measurement gaps, and the UE can determine whether each measurement meets a threshold measurement level. If the measurement threshold is met, the UE can determine to send a measurement report to the network (e.g., a base station). The network can then identify the measured frequency band that meets the measurement threshold as a secondary cell group (SCG) on one of the cells for which the UE sent the measurement report. However, the network may add secondary cell groups to a cell based on the UE performing measurements in a random order. Therefore, the cell may not correspond to a high-quality or low-interference cell when compared to other frequency bands that have not yet been measured. For example, when other frequency bands can exceed the threshold by a large amount and therefore can correspond to a higher-quality cell, the UE may send a measurement report for a first frequency that meets the threshold. Furthermore, in some cases, the UE may not support gapless measurement, which could affect throughput and lead to performance degradation or increased latency.
[0049] Therefore, the UE can sort and prioritize a set of frequency bands indicated by the network based on a set of parameters. These parameters can be applied in ranking order, with parameters applied first, second, and so on, to sort and prioritize the frequency bands. Some examples of parameters may include one or more of the following: frequency range, presence of the frequency band in a database, duplex mode of the frequency band, trigger time to trigger (TTT) of the frequency band, bandwidth, or any combination of the above, to name just a few. These parameters can then be applied in ranking order. For example, the frequency range parameter can be applied first, followed by the presence of the frequency band in the database, then the duplex mode parameter, and so on. By applying the parameters in ranking order, the UE can generate a prioritized list of frequency bands. The UE can then open a set of measurement gaps for each frequency band based on the prioritized list (e.g., in descending order).
[0050] The UE can then perform measurements on the frequency bands based on the highest priority bands. The measurements can meet criteria set by the network. When a frequency band meets both network and UE criteria (e.g., UE thresholds), the UE can send a measurement report for that frequency band to the network. However, if the measurement is below a UE threshold (e.g., a threshold for Reference Signal Received Power (RSRP) in dBm or a threshold for Reference Signal Received Quality (RSRQ) in dB), the UE can delay sending the measurement report for a certain amount of time (e.g., a set number of milliseconds). Delaying the transmission of the measurement report to the network facilitates the measurement of other configured frequencies according to the ordered sequence. This allows the UE to consider other frequency band options before the frequency band measurement report is reported to the network.
[0051] Due to this latency, the scheduling for sending frequency band measurement reports may not be aligned with the scheduling for measuring frequency bands. However, this process allows the UE to identify frequency bands (e.g., corresponding to cells) that meet both network and UE thresholds. Once the UE identifies a cell that meets both thresholds, it can send a measurement report to the network, which includes an indication of the identified frequency band. Therefore, the UE can measure and report one or more frequency bands that have the least impact on throughput. In situations where the network can add cells as secondary cell groups (SCGs), prioritized frequency band measurements performed by the UE can prevent the network from adding SCGs to relatively weak cells.
[0052] First, aspects of this disclosure are described in the context of a wireless communication system. Then, aspects of this disclosure are described with respect to process flow. Further, aspects of this disclosure are illustrated by apparatus diagrams, system diagrams, and flowcharts relating to techniques for enhancing the handling of network measurements, and are described with reference to these diagrams.
[0053] Figure 1 Examples of wireless communication systems 100 supporting techniques for enhanced handling of network measurements according to various aspects of this disclosure are shown. Wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, wireless communication system 100 may be a Long Term Evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.
[0054] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal transmission according to one or more radio access technologies.
[0055] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein may be able to communicate with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown in the image.
[0056] Base station 105 can communicate with core network 130, communicate with each other, or perform both operations. For example, base station 105 can interface with core network 130 via one or more backhaul links 132 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) on backhaul link 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via core network 130), or perform both operations. In some examples, backhaul link 120 may be or include one or more radio links.
[0057] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or other suitable terms.
[0058] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, and other examples, which may be implemented in various articles such as electrical appliances, vehicles, meters, and other examples.
[0059] The UE 115 described in this document may be able to communicate with various types of devices, such as other UE 115s that can sometimes act as relays, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown in the image.
[0060] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.
[0061] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition or control signaling that coordinates operation against other carriers. The carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be positioned according to a channel grid for discovery by UE 115. The carrier may operate in standalone mode, where UE 115 may initiate acquisition and connection via the carrier, or the carrier may operate in non-standalone mode, where different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.
[0062] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).
[0063] A carrier can be associated with a bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of defined bandwidths for a carrier for a radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication over a carrier bandwidth, or can be configured to support communication over a single carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.
[0064] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Extended OFDM (DFT-S-OFDM). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.
[0065] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.
[0066] It can be expressed in a basic unit of time (which can be, for example, T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0067] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., this depends on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.
[0068] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).
[0069] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by multiple symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions against control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a particular UE 115.
[0070] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., on a carrier) to communicate with base station 105 and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of base station 105, the range of such cells can range from small areas (e.g., structures, subsets of structures) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, and other examples.
[0071] Macro cells can cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 115 with a service subscription to a network provider supporting macro cells. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a residence or office). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.
[0072] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).
[0073] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.
[0074] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.
[0075] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UE 115 devices can be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.
[0076] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception, rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communication, when operating on limited bandwidth (e.g., according to narrowband communication), or when a combination of these techniques is used. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs) within a carrier, within a carrier's guard band, or outside a carrier.
[0077] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.
[0078] In some examples, UE 115 may also be able to communicate directly with other UE 115s on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, groups of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.
[0079] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicle may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. The vehicle may signal information relating to traffic conditions, signal control, weather, safety, emergencies, or any other information relating to the V2X system. In some examples, a vehicle in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.
[0080] 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) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to IP service 150 for one or more network operators. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0081] Some network devices (such as base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).
[0082] Wireless communication system 100 can operate using one or more frequency bands (e.g., in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz can be referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficient to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Compared to the transmission of smaller frequencies and longer waves using the lower frequencies (HF) or very high frequencies (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).
[0083] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as the centimeter band) or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be smaller and more closely spaced compared to UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, EHF transmissions may suffer even greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary depending on the country or regulatory authority.
[0084] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), unlicensed radio frequency spectrum band (e.g., LTE unlicensed (LTE-U)) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.
[0085] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have antenna arrays with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Alternatively or additionally, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.
[0086] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).
[0087] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to the orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with an orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).
[0088] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as base station 105) or by a receiving device (such as UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.
[0089] Base station 105 may transmit signals (e.g., data signals associated with the receiving device) in a single beam direction (e.g., the direction associated with the receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or otherwise acceptable signal quality.
[0090] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate combined beams for (e.g., from base station 105 to UE 115) transmissions. UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to a configured number of beams spanning the system bandwidth or one or more subbands. Base station 105 can transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 can provide feedback on beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).
[0091] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions). In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).
[0092] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for transmission over logical channels. The Media Access Control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.
[0093] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception on communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.
[0094] UE 115 can measure a frequency set based on the priority of parameters received from the network via base station 105 or another network device. UE 115 can establish an RRC connection with base station 105. UE 115 can receive parameters associated with the frequency band set from base station 105, which indicate the priority of each frequency band in the frequency band set. UE 115 can then measure one or more frequencies of at least one frequency band in the frequency band set based on the priority. UE 115 can then send a measurement report to base station 105 after a time delay, the measurement report including the measurements of one or more frequency bands in the frequency band set.
[0095] Figure 2 Examples of wireless communication systems 200 supporting techniques for enhanced handling of network measurements according to various aspects of this disclosure are shown. In some examples, wireless communication system 200 may implement aspects of wireless communication system 100 (such as...) Figure 1(As shown in the diagram). For example, wireless communication system 200 may include base station 105 and UE 115, which may be referenced. Figure 1 Examples of corresponding devices are described. Wireless communication systems can illustrate examples of systems that support simultaneous transmission across multiple uplink channels on a resource set.
[0096] In some cases, UE 115 can establish an RRC connection with base station 105. Once the RRC connection is established, UE 115 can receive parameters 205 from base station 105 on downlink channel 215. Parameters 205 can be associated with a series of frequency bands, where these parameters indicate that UE 115 can use them to measure the priority of the associated frequency bands. For example, these parameters may include one or more of the following: frequency range (FR) of the frequency band, database presence, duplex mode, trigger time (TTT) or bandwidth, or any combination thereof. Parameters 205 can be applied to the series of frequency bands in a specific ranking order to prioritize the series of frequency bands. The ranking order to be applied for parameters 205 can also be indicated to UE 115 in signaling from base station 105, or UE 115 can determine the order.
[0097] For example, UE 115 can receive parameter 205 and determine that these parameters can be applied in a specific order. In some cases, this order can be frequency range, database presence, duplex mode, TTT configuration, and bandwidth configuration. Therefore, the frequency range parameter can be applied to the series of frequency bands first. For example, the frequency range corresponding to the first frequency range (e.g., FR2 NR) can take precedence over the frequency band corresponding to the second frequency range (e.g., FR1 LTE). In one example, the frequency range of the first frequency band can correspond to FR1, and the frequency range of the second frequency band can correspond to FR2. Parameter 205 can indicate that the frequency bands in the FR2 frequency range will be prioritized. Therefore, the second frequency band in FR2 can take precedence over the first frequency band. As a result, the series of frequency bands can be ordered such that the frequency bands in FR2 take precedence over the frequency bands in FR1.
[0098] Secondly, the database presence parameter can be applied to this series of frequency bands. Parameter 205 can indicate that frequency bands present in the database should be prioritized; therefore, frequency bands present in the database can take precedence over those not present in the database. As a result, the frequency bands can now be sorted in such a way that higher priority frequency bands are those present in the database and also in FR2.
[0099] Third, duplex mode parameters can be applied to this series of frequency bands. Parameter 205 can indicate that frequency bands in the Time Division Duplex (TDD) bands take precedence over Frequency Division Duplex (FDD) bands. Therefore, TDD bands can take precedence over FDD bands. As a result, the frequency bands can now be sorted in such a way that the higher-priority bands are those that exist in the database as TDD bands and correspond to FR2.
[0100] Fourth, the TTT parameter can be applied to this series of frequency bands. This can be done as follows: frequency bands with lower TTTs are prioritized over those with higher TTTs. Therefore, the frequency bands can be sorted in order from lowest to highest TTT. As a result, the frequency bands can now be sorted in such a way that the higher-priority bands have the lowest TTTs, are TDD bands, exist in the database, and are in FR2.
[0101] Fifth, bandwidth parameters can be applied to this series of frequency bands. This can be done as follows: frequency bands with higher bandwidth are prioritized over those with lower bandwidth. Therefore, the frequency bands can be sorted in order from highest to lowest bandwidth. As a result, the frequency bands can now be sorted in such a way that the higher-priority bands have the highest bandwidth, lowest TTT, are TDD bands, exist in the database, and are in FR2.
[0102] Once UE 115 has applied the parameters sequentially, the series of frequency bands can be sorted into a priority list. UE 115 can then open gaps for the frequency bands in descending order of priority. For example, UE 115 can open gaps for the frequency bands in the first list, since the first frequency band corresponds to the highest priority frequency band. UE 115 can then open gaps for the frequency bands in the second list, since it corresponds to the second highest priority frequency band. UE 115 can continue until it has opened gaps for the series of frequency bands in descending order. Once the gaps have been opened, UE 115 can measure the frequency bands in descending order of priority.
[0103] UE 115 can identify network measurement thresholds. These thresholds may include an RSRP threshold, an RSRQ threshold, or both, set by base station 105. UE 115 can measure each frequency band in priority order, and UE 115 can determine whether the band measurement meets a network measurement threshold (e.g., meets an RSRP network threshold, an RSRQ network threshold, or both). UE 115 can then determine whether the band measurement meets a UE threshold (e.g., a UE measurement threshold different from the network measurement threshold), which may correspond to a threshold in dBm for RSRP measurements or in dB for RSRQ measurements (e.g., relative to the network measurement threshold, as set by the UE, indicated by the base station, or both). When a band measurement meets both the network and UE thresholds, the UE can send a measurement report for that band to the network. However, when the frequency band measurement does not meet the UE threshold (e.g., even if the measurement meets the network measurement threshold), the UE 115 can delay sending the measurement report for a set amount of time. Therefore, based on the delay, the UE 115 can continue measuring other frequency bands before reporting the frequency band measurement report.
[0104] In some examples, the network RSRP threshold can be set to -90dBm, and the network RSRQ threshold can be set to -15dB. In some cases, the UE RSRP threshold can be set to -85dBm (e.g., 5dBm greater than the network RSRP threshold), and the UE RSRQ threshold can be set to -10dB (e.g., 5dB greater than the network RSRQ threshold). The UE can measure a frequency band and determine that the RSRP for that band is -87dBm and the RSRQ for that band is -12dB. Therefore, the UE can determine that the -87dBm RSRP measurement for this frequency band meets (e.g., above) the network RSRP threshold of -90dBm, the -12dB RSRQ measurement for this frequency band meets (e.g., above) the network RSRQ threshold of -15dB, but the -87dBm RSRP measurement for this frequency band does not meet (e.g., below) the UE RSRP threshold of -85dBm, and the -12dB RSRQ measurement for this frequency band meets (e.g., below) the UERSRQ threshold of -10dB. Therefore, the UE can delay sending the measurement report for a set amount of time, allowing the UE to perform additional frequency band measurements (e.g., based on priority). In some examples, UE 115 can sort and measure three different frequency bands sequentially or by priority. If UE 115 wants to avoid delaying the measurement report, UE 115 can send a measurement report for the first frequency band (e.g., corresponding to the highest priority) to base station 105 without delay (if the first frequency band meets the network threshold). In this scenario, base station 105 can select a cell based on the first frequency band. However, while the second and third frequency bands have lower priority compared to the first frequency band, they can correspond to measurements that satisfy both network and UE thresholds. By delaying the transmission of measurement reports for the frequency bands used for the first measurement, UE 115 can ensure that it can send measurement reports for the frequency bands corresponding to higher quality and lower interference to base station 105 first.
[0105] In another scenario, UE 115 can sort the set of frequency bands identified by UE 115 based on a set of parameters. UE 115 can send an indication of the sorted frequency bands to base station 105. This allows base station 105 to verify or modify the prioritized list based on other factors of UE 115. In some cases, base station 105 can modify the prioritized frequency band list based on load balancing at base station 105. Base station 105 can modify the prioritized list and then send an indication of the modified frequency band list (e.g., frequency band configuration) to UE 115. UE 115 can then use the prioritized list received and modified from base station 105 to determine the order of frequency band measurements.
[0106] Figure 3 An example of a process flow 300 supporting techniques for enhanced handling of network measurements according to various aspects of this disclosure is shown. Process flow 300 can implement a wireless communication system 100 (such as...). Figure 1 (as shown) and wireless communication system 200 (as shown) Figure 2 (As shown in the diagram). Process flow 300 includes UE 115 and base station 105, which can be as follows: Figure 1 and Figure 2 Examples of UE 115 and base station 105 described herein. UE 115 and base station 105 may communicate as part of a wireless communication system (such as wireless communication system 100 or wireless communication system 200).
[0107] At point 305, UE 115 and base station 105 can establish an RRC connection. The RRC connection can be an example of an RRC connection mode (e.g., RRC_Connected) for UE 115.
[0108] In some cases, UE 115 may send an indication to base station 105 of the priority of each frequency band in the frequency band set for measurement. In these cases, UE 115 may receive the configuration of the frequency band set based on this indication. The indication of priority may be based on the location of UE 115. For example, the indication of priority may include an indication of the frequency bands available to UE 115 at its location.
[0109] At 310, UE 115 can receive parameters associated with the frequency band set from base station 105. These parameters can indicate the priority of each frequency band in the frequency band set. UE 115 can sort each frequency band in the frequency band set based on these parameters. The priority can be determined by measuring each frequency band in the frequency band set in the order of frequency range, frequency band presence in the database, duplex configuration, TTT configuration, and system bandwidth configuration.
[0110] For example, UE 115 can first prioritize frequency bands based on frequency range. In this case, UE 115 can prioritize frequency bands corresponding to a first radio access technology (RAT) (e.g., NR, corresponding to FR2) over frequency bands corresponding to a second RAT (e.g., LTE, corresponding to FR1). Then, UE 115 can prioritize frequency bands based on their presence in a database, where UE 115 can prioritize frequency bands present in the database over those not present. Then, UE 115 can prioritize frequency bands based on duplex configuration. For example, UE 115 can prioritize frequency bands configured for TDD (e.g., NR TDD) over those configured for FDD (e.g., NR FDD). Then, UE 115 can prioritize frequency bands based on which frequency bands correspond to low TTT. Finally, UE 115 can prioritize frequency bands based on frequency bands corresponding to higher system bandwidth.
[0111] At 315, UE 115 can measure each frequency band in the frequency band set based on priority. Measurements may include RSRP measurements, RSRQ measurements, or both. UE 115 can perform measurements for each frequency band according to a priority order based on these parameters.
[0112] UE 115 can configure measurement gaps for each frequency band in the frequency band set based on priority. The first measurement gap can be associated with the first frequency band in the frequency band set.
[0113] At position 320, UE 115 can send a measurement report to base station 105, which includes measurements of one or more frequency bands in the set of frequency bands. UE 115 can send a measurement report for the first measurement based on the first measurement of the first frequency band satisfying a measurement threshold. The measurement threshold may include a network measurement threshold and a UE measurement threshold. For example, UE 115 can measure the first frequency band, and UE 115 can determine that the first frequency band satisfies the network measurement threshold. UE 115 can then determine whether the measurement of the first frequency band also satisfies the UE measurement threshold. Then, UE 115 can determine whether to send a measurement report based on the first frequency band measurement satisfying both measurement thresholds.
[0114] UE 115 can also send a measurement report after a time delay based on at least one measurement satisfying a network measurement threshold but failing to satisfy a UE measurement threshold. UE 115 can perform additional measurements on one or more frequency bands in the frequency band set based on the delay in sending the measurement report (according to a priority list). For example, UE 115 can measure a first frequency band in the frequency band set. The measured first frequency may satisfy the network threshold but may not satisfy the UE measurement threshold. In this case, UE 115 can delay the transmission of the measurement report. UE 115 can continue measuring other frequency bands in the frequency band set during the delay. Therefore, UE 115 may be able to identify frequency bands with higher quality (e.g., satisfying both the network measurement threshold and the UE measurement threshold) compared to the first frequency band, and UE 115 can send a report for the identified frequency band.
