Patent Description:
Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (for example, bandwidth or transmit power).

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments (UEs) to communicate on a municipal, national, regional, and even global level. New Radio (NR), which may also be referred to as <NUM>, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM or SC-FDMA (for example, also known as discrete Fourier transform spread OFDM.

(DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. Preferably, these improvements are applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

In some networks, a base station may transmit one or more reference signals to a UE for beam failure detection. The UE may attempt to detect and measure the reference signals. Based at least in part on the UE failing to detect a threshold quantity of the reference signals or measurements of a threshold quantity of the reference signals satisfying a measurement threshold, the UE may determine that beam failure has occurred. <CIT> describes a user terminal and a method of wireless communication. <CIT> describes a user terminal and a method of wireless communication. <CIT> describes a user terminal and a method of wireless communication.

Aspects generally include a method, apparatus, system, computer program product, non-transitory computer-readable medium, user equipment, base station, wireless communication device, or processing system as substantially described with reference to and as illustrated by the drawings and specification.

The foregoing has outlined rather broadly the features and technical advantages of examples in accordance with the disclosure in order that the detailed description that follows may be better understood. Such equivalent constructions are part of the invention, provided that they do not depart from the scope of the appended claims.

It is to be noted, however, that the appended drawings illustrate only some typical aspects of this disclosure and are therefore not to be considered limiting of its scope, for the description may admit to other equally effective aspects.

This disclosure may, however, be embodied in many different forms within the scope of the appended claims and are not to be construed as limited to any specific structure or function described in the following. Based on the teachings herein one skilled in the art may appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure that falls within the scope of the appended claims. For example, an apparatus may be implemented or a method may be practiced using any quantity of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality, provided that it falls within the scope of the claims. Any aspect of the disclosure disclosed herein may be embodied within the scope of a claim.

These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination of hardware and software.

Various aspects relate generally to a UE transmitting, and a base station receiving, an indication of a quantity of reference signals that the UE supports for beam failure detection (for example, secondary cell beam failure detection) of a wireless connection. Some aspects more specifically relate to the UE transmitting an indication of a quantity of reference signals, across all component carriers (for example, of the wireless connections), that the UE supports for beam failure detection. In some aspects, the UE may transmit an indication of a quantity of reference signals supported across all component carriers per frequency range (for example, frequency range <NUM> (FR1) or frequency range <NUM> (FR2), among other examples) or an indication of a quantity of reference signals supported across all component carriers (for example, a total number of component carriers supported in all frequency ranges). In some aspects, the component carriers may include a special cell (SPCell) and one or more secondary cells (SCells). In some aspects, a numerology or a subcarrier spacing (SCS) of a slot, sub-slot, or other time domain resource during which the UE supports the quantity of reference signals may be associated with a numerology or an SCS of a downlink bandwidth part of a component carrier of the wireless connection. For example, the numerology may be a smallest numerology of all component carriers of the wireless connection or the SCS may be a largest subcarrier spacing of all component carriers of the wireless connection. In some aspects, a numerology or an SCS of a slot, sub-slot, or other time domain resource during which the UE supports the quantity of reference signals may be associated with a reference numerology or SCS (for example, a configured numerology or SCS).

A base station may determine a quantity of reference signals to transmit to the UE based at least in part on the indication. The UE may receive, and the base station may transmit, one or more reference signals in a slot of the one or more slots based at least in part on transmitting the indication of the quantity of reference signals. The UE may transmit an indication of beam failure detection (for example, an indication of beam failure or an indication of no beam failure) based at least in part on measurements of the one or more reference signals. Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, the described techniques can be used by a base station to configure a quantity of reference signals used to perform beam failure detection, with the quantity based at least in part on a number of reference signals supported by the UE. In this way, the base station may conserve power, computing, communication, or network resources that may otherwise have been consumed by transmitting a quantity of reference signals for beam failure detection that is greater than the quantity of reference signals supported by the UE. Additionally or alternatively, the base station may transmit an increased quantity of reference signals, based at least in part on the UE supporting the increased quantity of reference signals, which may reduce a latency in detecting beam failure of the secondary cells. In this way, the base station may conserve power, computing, communication, or network resources that may otherwise have been consumed by attempting to communicate after an undetected beam failure.

<FIG> is a diagram illustrating an example of a wireless network in accordance with the present disclosure. The wireless network may be or may include elements of a <NUM> (NR) network or an LTE network, among other examples. The wireless network may include one or more base stations <NUM> (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a <NUM> node B (NB), an access point, or a transmit receive point (TRP), among other examples. In 3GPP, the term "cell" can refer to a coverage area of a BS or a BS subsystem serving this coverage area, depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs having association with the femto cell (for example, UEs in a closed subscriber group (CSG)). A BS may support one or multiple (for example, three) cells.

The wireless network may be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, or relay BSs. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network. For example, macro BSs may have a high transmit power level (for example, <NUM> to <NUM> watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (for example, <NUM> to <NUM> watts). A network controller <NUM> may couple to the set of BSs 102a, 102b, 110a and 110b, and may provide coordination and control for these BSs. The BSs may also communicate with one another, for example, directly or indirectly via a wireless or wireline backhaul.

In some aspects, a cell may not be stationary, rather, the geographic area of the cell may move in accordance with the location of a mobile BS. In some aspects, the BSs may be interconnected to one another or to one or more other BSs or network nodes (not shown) in the wireless network through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

The wireless network may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (for example, a BS or a UE) and send a transmission of the data to a downstream station (for example, a UE or a BS). A relay BS may also be referred to as a relay station, a relay base station, or a relay, among other examples.

UEs <NUM> (for example, 120a, 120b, 120c) may be dispersed throughout the wireless network, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, or a station, among other examples. A UE may be a cellular phone (for example, a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (for example, smart ring, smart bracelet)), an entertainment device (for example, a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless medium.

MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors or location tags, among other examples, that may communicate with a base station, another device (for example, remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (for example, a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of-Things (IoT) devices, or may be implemented as NB-IoT (narrowband internet of things) devices. UE <NUM> may be included inside a housing that houses components of UE <NUM>, such as processor components or memory components, among other examples.

In general, any quantity of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular radio access technology (RAT) and may operate on one or more frequencies or frequency channels. A frequency may also be referred to as a carrier among other examples.

In some aspects, two or more UEs <NUM> (for example, shown as UE 120a and UE 120e) may communicate directly with one another using one or more sidelink channels (for example, without using a base station <NUM> as an intermediary). For example, the UEs <NUM> may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (for example, which may include a vehicle-to-vehicle (V2V) protocol or a vehicle-to-infrastructure (V2I) protocol), a mesh network, or a combination thereof. In such examples, the UE <NUM> may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by the base station <NUM>.

Devices of the wireless network may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, or channels. For example, devices of the wireless network may communicate using an operating band having a first frequency range (FR1), which may span from <NUM> to <NUM>. As another example, devices of the wireless network may communicate using an operating band having a second frequency range (FR2), which may span from <NUM> to <NUM>. Thus, unless specifically stated otherwise, it should be understood that the term "sub-<NUM>" may broadly represent frequencies less than <NUM>, frequencies within FR1, mid-band frequencies (for example, greater than <NUM>), or a combination thereof. Similarly, unless specifically stated otherwise, it should be understood that the term "millimeter wave" may broadly represent frequencies within the EHF band, frequencies within FR2, mid-band frequencies (for example, less than <NUM>), or a combination thereof. The frequencies included in FR1 and FR2 may be modified, and techniques described herein are applicable to those modified frequency ranges.

Transmit processor <NUM> may also process system information (for example, for semi-static resource partitioning information (SRPI) among other examples) and control information (for example, CQI requests, grants, or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor <NUM> may also generate reference symbols for reference signals and synchronization signals. A transmit (TX) multiple-input multiple-output (MIMO) processor <NUM> may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each MOD <NUM> may process a respective output symbol stream (for example, for OFDM among other examples) to obtain an output sample stream. Each MOD <NUM> may further process (for example, convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from MODs 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

At UE <NUM>, antennas 252a through 252r may receive the downlink signals from base station <NUM> or other base stations and may provide received signals to R demodulators (DEMODs) 254a through 254r, respectively. Each DEMOD <NUM> may condition (for example, filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each DEMOD <NUM> may further process the input samples (for example, for OFDM) to obtain received symbols. A MIMO detector <NUM> may obtain received symbols from all R DEMODs 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor <NUM> may process (for example, decode) the detected symbols, provide decoded data for UE <NUM> to a data sink <NUM>, and provide decoded control information and system information to a controller/processor <NUM>. The term "controller/processor" may refer to one or more controllers, one or more processors, or a combination of one or more controllers and one or more processors. A channel processor may determine one or more of a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, or a channel quality indicator (CQI) parameter, among other examples.

Antennas (such as antennas 234a through 234t or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, or antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include one or more antenna elements. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include a set of coplanar antenna elements or a set of non-coplanar antenna elements. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include antenna elements within a single housing or antenna elements within multiple housings. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include one or more antenna elements coupled to one or more transmission or reception components, such as one or more components of <FIG>.

On the uplink, at UE <NUM>, a transmit processor <NUM> may receive and process data from a data source <NUM> as well as control information (for example, for reports including RSRP, RSSI, RSRQ, or CQI) from controller/processor <NUM>. The symbols from transmit processor <NUM> may be precoded by a TX MIMO processor <NUM> if applicable, further processed by MODs 254a through 254r (for example, for discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) or orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM)), and transmitted to base station <NUM>. In some aspects, a modulator and a demodulator (for example, MOD/DEMOD <NUM>) of the UE <NUM> may be included in a modem of the UE <NUM>. The transceiver may include any combination of antenna(s) <NUM>, modulators <NUM>, demodulators <NUM>, MIMO detector <NUM>, receive processor <NUM>, transmit processor <NUM>, or TX MIMO processor <NUM>. The transceiver may be used by a processor (for example, controller/processor <NUM>) and memory <NUM> to perform aspects of any of the methods described herein.

At base station <NUM>, the uplink signals from UE <NUM> and other UEs may be received by antennas <NUM>, processed by DEMODs <NUM>, detected by a MIMO detector <NUM> if applicable, and further processed by a receive processor <NUM> to obtain decoded data and control information sent by UE <NUM>. Base station <NUM> may include a scheduler <NUM> to schedule UEs <NUM> for downlink and uplink communications. In some aspects, a modulator and a demodulator (for example, MOD/DEMOD <NUM>) of the base station <NUM> may be included in a modem of the base station <NUM>. The transceiver may include any combination of antenna(s) <NUM>, modulators <NUM>, demodulators <NUM>, MIMO detector <NUM>, receive processor <NUM>, transmit processor <NUM>, or TX MIMO processor <NUM>. The transceiver may be used by a processor (for example, controller/processor <NUM>) and memory <NUM> to perform aspects of any of the methods described herein.

Controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, or any other component(s) of <FIG> may perform one or more techniques associated with indicating user equipment capability for beam failure detection, as described in more detail elsewhere herein. For example, controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, or any other component(s) of <FIG> may perform or direct operations of, for example, process <NUM> of <FIG>, process <NUM> of <FIG>, or other processes as described herein. Memories <NUM> and <NUM> may store data and program codes for base station <NUM> and UE <NUM>, respectively. In some aspects, memory <NUM> or memory <NUM> may include a non-transitory computer-readable medium storing one or more instructions (for example, code or program code) for wireless communication. For example, the one or more instructions, when executed (for example, directly, or after compiling, converting, or interpreting) by one or more processors of the base station <NUM> or the UE <NUM>, may cause the one or more processors, the UE <NUM>, or the base station <NUM> to perform or direct operations of, for example, process <NUM> of <FIG>, process <NUM> of <FIG>, or other processes as described herein.

In some aspects, the base station includes means for receiving an indication of a quantity of reference signals that a UE supports for beam failure detection of a wireless connection; transmitting one or more reference signals in a slot of the one or more slots based at least in part on transmitting the indication of the quantity of reference signals; and/or receiving an indication of beam failure detection of the wireless connection based at least in part on measurements of the transmitted one or more reference signals.

In some aspects, the base station includes means for determining a quantity of reference signals to transmit to the UE for beam failure detection of the wireless connection based at least in part on the indication.

In some networks, a base station may transmit one or more reference signals to a UE for beam failure detection. The UE may attempt to detect and measure the reference signals. Based at least in part on the UE failing to detect a threshold quantity of the reference signals or measurements of a threshold quantity of the reference signals satisfying a measurement threshold, the UE may determine that beam failure has occurred. However, the base station may unnecessarily consume power, computing, communication, or network resources based at least in part on transmitting a quantity of reference signals for beam failure detection that is greater than a quantity of reference signals supported by the UE. Additionally or alternatively, the base station may consume power, computing, communication, or network resources by attempting to communicate after an undetected beam failure based at least in part on transmitting fewer reference signals for beam failure detection than the quantity of reference signals supported by the UE.

In some aspects described herein, a UE may transmit an indication of a quantity of reference signals that the UE supports, for receiving during a slot, for beam failure detection of a wireless connection. The UE may communicate via the wireless connection based at least in part on the indication. For example, the UE may receive a quantity of reference signals (for example, in a slot), for beam failure detection, with the quantity of received reference signals being less than or equal to the indicated quantity of reference signals that the UE supports for beam failure detection. The UE may use the quantity of reference signals for beam failure detection and/or may transmit an indication of beam failure detection for the secondary cells. In this way, the base station may conserve power, computing, communication, or network resources that may otherwise have been consumed by transmitting a quantity of reference signals for beam failure detection that is greater than the quantity of reference signals supported by the UE. Additionally or alternatively, the base station may transmit an increased quantity of reference signals, based at least in part on the UE supporting the increased quantity of reference signals, which may reduce a latency in detecting beam failure of the secondary cells. In this way, the base station may conserve power, computing, communication, or network resources that may otherwise have been consumed by attempting to communicate after an undetected beam failure.

<FIG> is a diagram illustrating an example <NUM> of indicating user equipment capability for beam failure detection, in accordance with the present disclosure. As shown in <FIG>, a UE (for example, UE <NUM>) may communicate with a base station (for example, base station <NUM>). In some aspects, the UE and the base station may be part of a first wireless network (for example, wireless network <NUM>). In some aspects, the UE and the base station may communicate via one or more of a primary cell group or a secondary cell group. The secondary cell group may include a special cell (SPCell) or one or more secondary cells (SCells).

In a first operation <NUM>, the UE may receive configuration information (for example, from a base station) or determine the configuration information based at least in part on a communication standard. In some aspects, the UE may receive the configuration information via one or more of a system information block, radio resource control (RRC) signaling, medium access control control elements (MAC CEs), or a sidelink communication, among other examples. In some aspects, the configuration information may include an indication of one or more configuration parameters (for example, already known to the UE) for selection by the UE, or explicit configuration information for the UE to use to configure the UE, among other examples.

In some aspects, the configuration information may indicate that the UE is to determine a quantity of reference signals that the UE supports for beam failure detection. In some aspects, the configuration information may indicate how the UE is to determine the quantity of reference signals that the UE supports for beam failure detection. In some aspects, the configuration information may indicate that the UE is to transmit an indication of the quantity of reference signals that the UE supports for beam failure detection. In some aspects, the configuration information may indicate how the UE is to transmit the indication of the quantity of reference signals that the UE supports for beam failure detection.

In a second operation <NUM>, the UE may be configured based at least in part on the configuration information. In some aspects, the UE may be configured to perform one or more operations described herein.

In a third operation <NUM>, the UE may determine the quantity of reference signals that the UE supports for beam failure detection (for example, secondary cell beam failure detection). In some aspects, the quantity based at least in part on a configuration of the UE (for example, a power state of the UE), components of the UE (for example, a quantity of baseband components, a quantity of antenna groups, or computing components, among other examples), or an operation mode of the UE (for example, a dual connectivity mode). In some aspects, the configuration of the UE may be based at least in part on the configuration information received, for example, from the base station.

In some aspects, the quantity of reference signals that the UE supports for beam failure detection may include a maximum quantity of reference signals that the UE supports for beam failure detection of the wireless connection. In some aspects, the quantity of reference signals that the UE supports for beam failure detection may include a selected quantity, that is less than or equal to the maximum quantity, of reference signals that the UE supports for beam failure detection.

In some aspects, the quantity of reference signals that the UE supports for beam failure detection may include a quantity of reference signals that the UE supports for beam failure detection on a first set of component carriers of a first frequency range or a quantity of reference signals that that the UE supports for beam failure detection on a second set of component carriers of a second frequency range (for example, separate quantities per frequency range (maxNumberResWithinSlotAcrossCC-OneFR-r16)). The first set of component carriers of the first frequency range may include a special cell and one or more secondary cells of the first frequency range. The second set of component carriers of the second frequency range may include a special cell and one or more secondary cells of the second frequency range.

In some aspects, the quantity of reference signals that the UE supports for beam failure detection may include a quantity of reference signals that the UE supports for beam failure detection on a set of component carriers of multiple frequency ranges (maxTotalResourcesForAcrossFreqRanges-r16). For example, the quantity of reference signals that the UE supports for beam failure detection may include a total quantity of reference signals that the UE supports for the first frequency range and the second frequency range (for example, a combined quantity for two or more frequency ranges). The set of component carriers of the multiple frequency ranges may include one or more special cells (for example, a special cell per frequency range) and one or more secondary cells of the multiple frequency ranges.

In some aspects, the quantity of reference signals that the UE supports for beam failure detection may include a quantity of reference signals that the UE supports for beam failure detection during a slot, a sub-slot, a set of slots, or another time-domain resource. A numerology of the time domain resource (for example, a slot) for measuring the reference signals may be based at least in part on a particular numerology of a particular bandwidth part of component carriers over which the UE supports the quantity of reference signals. In some aspects, the particular bandwidth part may be a bandwidth part having a smallest numerology among bandwidth parts of the component carriers over which the UE supports the quantity of reference signals. In some aspects, a numerology of a time domain resource for measuring the reference signals may be based at least in part on a configured numerology (for example, specified in configuration information or a communication standard, among other examples). In some aspects, a subcarrier spacing of a time domain resource for measuring the reference signals is based at least in part on a particular subcarrier spacing of a particular bandwidth part of component carriers over which the UE supports the quantity of reference signals. In some aspects, the particular bandwidth part may be a bandwidth part having a largest subcarrier spacing among bandwidth parts of the component carriers over which the UE supports the quantity of reference signals. In some aspects, a subcarrier spacing of a time domain resource for measuring the reference signals is based at least in part on a configured subcarrier spacing (for example, specified in configuration information or a communication standard, among other examples).

In a fourth operation <NUM>, the UE may transmit, and the base station may receive, an indication of the quantity of reference signals that the UE supports for beam failure detection (for example, maxTotalResourcesForAcrossFreqRanges-r16 or maxNumberResWithinSlotAcrossCC-OneFR-r16). In some aspects, the indication may indicate a quantity of resources associated with the reference signals that the UE supports for beam failure detection (for example, to measure for beam failure detection). For example, the quantity of resources may be a quantity of resources across all component carriers in a single frequency range, or in all frequency ranges, among other examples. In some aspects, the indication may indicate a quantity of reference signals the UE supports for beam failure detection (for example, to measure) within a slot (for example, across all component carriers in a frequency range) (for example, maxNumberResWithinSlotAcrossCC-AcrossFR-r16). In some aspects, the UE may transmit the indication via a control message. For example, the UE may transmit the indication via a physical uplink control channel communication. In some aspects, the UE may communicate with the base station (for example, via an associated wireless connection) based at least in part on the indication of the quantity of reference signals that the UE supports for beam failure detection. For example, the UE may receive one or more reference signals for beam failure detection from the base station or may transmit an indication of beam failure detection.

In a fifth operation <NUM>, the base station may determine a quantity of reference signals to transmit to the UE for beam failure detection. In some aspects, the quantity may be based in part on the indication of the quantity of reference signals that the UE supports for beam failure detection. For example, the quantity of reference signals to transmit to the UE may be a same quantity as, or a quantity that is less than, the quantity of reference signals that the UE supports for beam failure detection. In some aspects, the base station may determine to transmit a quantity that is less than the quantity of reference signals that the UE supports for beam failure detection based at least in part on cell traffic or a likelihood of beam failure detection (for example, based at least in part on channel condition metrics, RSRP parameters, RSSI parameters, RSRQ parameters, or CQI parameters, among other examples).

In a sixth operation <NUM>, the UE may receive, and the base station may transmit, the quantity of reference signals to the UE for beam failure detection (for example, within a slot). In some aspects, the reference signals may include synchronization signal physical broadcast channel blocks or channel state information reference signals (CSI-RSs). In some aspects, the CSI-RSs may include one or more non-zero-power (NZP) CSI-RSs, one or more aperiodic CSI-RSs, one or more periodic CSI-RSs, or one or more semi-persistent CSI-RSs. Receiving the quantity of reference signals may include measuring the quantity of reference signals, attempting to measure the quantity of reference signals, and/or generating a report of measurements of the quantity of reference signals.

In a seventh operation <NUM>, the UE may perform beam failure detection. In some aspects, the UE may attempt to detect and measure the quantity of reference signals (for example, using the secondary cells). The UE may determine whether secondary beam failure has occurred for a secondary cell based at least in part on the UE failing to detect a threshold quantity of the reference signals or measurements of a threshold quantity of the reference signals satisfying a measurement threshold.

In an eighth operation <NUM>, the UE may transmit an indication of beam failure detection. For example, the UE may transmit the indication of beam failure detection via a secondary cell, a special cell, or a primary cell. In some aspects, the UE may transmit the indication of beam failure detection via a control message. In some aspects, the indication of beam failure detection may include an indication (for example, an explicit indication) of beam failure for the secondary cell. In some aspects, the indication of beam failure detection may include an indication (for example, an implicit indication or an explicit indication) of no beam failure for the secondary cell.

Based at least in part on the UE receiving a quantity of reference signals, for beam failure detection, with the quantity of received reference signals being less than or equal to the indicated quantity of reference signals that the UE supports for beam failure detection, the base station may conserve power, computing, communication, or network resources that may otherwise have been consumed by transmitting a quantity of reference signals for beam failure detection that is greater than the quantity of reference signals supported by the UE. Additionally or alternatively, the base station may transmit an increased quantity of reference signals, based at least in part on the UE supporting the increased quantity of reference signals, which may reduce a latency in detecting beam failure of the secondary cells. In this way, the base station may conserve power, computing, communication, or network resources that may otherwise have been consumed by attempting to communicate after an undetected beam failure.
