TECHNICAL FIELD

[0002] This disclosure relates generally to wireless communications and, more specifically, to barge-in multipoint connections for peripheral Bluetooth devices.

DESCRIPTION OF THE RELATED TECHNOLOGY

[0003] Wireless communication networks are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. Some wireless communication networks may be capable of supporting communication with multiple users by sharing the available system resources (such as time, frequency, or power). Further, a wireless communication network may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM), among other examples. Wireless communication devices may communicate in accordance with any one or more of such wireless communication technologies, and may include wireless stations (STAs), wireless access points (APs), user equipment (UEs), network entities, or other wireless nodes.

[0004] In some systems, devices supporting Bluetooth connections may support up to a threshold quantity of connections concurrently, for example, based on resource availability, scheduling conflicts, or both. Once a device establishes the threshold quantity of connections, the device may not support connecting to any additional devices. In some cases, the device disables discovery and connection features to avoid establishing any further Bluetooth connections. However, such devices not supporting discover}’ and connection for some time periods may reduce the reliability of Bluetooth communications and may negatively impact the latency associated with Bluetooth connectivity.

SUMMARY

[0005] The systems, methods, and devices of this disclosure each have several innovative aspects, no single one of which is solely responsible for the desirable attributes disclosed herein.

[0006] One innovative aspect of the subject matter described in this disclosure can be implemented in a first wireless communication device. The first wireless communication device may include a processing system that includes processor circuitry and memory circuitry that stores code. The processing system may be configured to cause the first wireless communication device to establish a set of multiple communication links with a set of multiple wireless communication devices, the set of multiple communication links including at least a first wireless communication link corresponding to an idle connection with a second wireless communication device, receive a frequency hopping sequence packet including an indication of a Bluetooth device address corresponding to a third wireless communication device, disconnect the first wireless communication link corresponding to the idle connection based on the Bluetooth device address and a quantity of the set of multiple communication links satisfying a threshold quantify of communication links for the first ireless communication device, and establish a second communication link with the third wireless communication device based on disconnecting the first wireless communication link.

DETAILED DESCRIPTION

[0018] The following description is directed to some particular examples for the purposes of describing innovative aspects of this disclosure. However, a person having ordinary skill in the art will readily recognize that the teachings herein can be applied in a multitude of different ways. Some or all of the described examples may be implemented in any device, system or network that is capable of transmitting and receiving radio frequency (RF) signals according to one or more of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards, the IEEE 802.15 standards, the Bluetooth® standards as defined by the Bluetooth Special Interest Group (SIG), or the Long Term Evolution (LTE), 3G, 4G, 5G (New Radio (NR)) or 6G standards promulgated by the 3rd Generation Partnership Project (3GPP), among others. The described examples can be implemented in any suitable device, component, system or network that is capable of transmitting and receiving RF signals according to one or more of the following technologies or techniques: code division multiple access (CDMA), time division multiple access (TDMA), orthogonal frequency division multiplexing (OFDM), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), single-carrier FDMA (SC-FDMA), spatial division multiple access (SDMA). rate-splitting multiple access (RSMA), multi-user shared access (MUSA), single-user (SU) multiple-input multiple-output (MIMO) and multi-user (MU)-MIMO (MU-MIMO). The described examples also can be implemented using other wireless communication protocols or RF signals suitable for use in one or more of a wireless personal area network (WPAN), a wireless local area network (WLAN), a wireless wide area network (WWAN), a wireless metropolitan area network (WMAN), a nonterrestrial network (NTN), or an internet of things (IOT) network.

[0019] Various aspects relate generally to a wireless communication device supporting barge-in multipoint connections. Some aspects more specifically relate to a Bluetooth peripheral device maintaining support for discovery’ and connection when operating with multiple established wireless communication links. In some examples, the peripheral device may establish multiple connections satisfying a threshold (such as a maximum) quantify of connections supported by the peripheral device. The peripheral device may enable a truncated mode for discovery based on the quantity of currently established connections satisfying the threshold quantify of connections at the peripheral device. While operating in the truncated mode for discovery, the peripheral device may receive a packet indicating a Bluetooth device address (BD ADDR) for a central device and may refrain from responding to or processing the packet. Instead, the peripheral device may determine whether to connect with the central device based on the BD ADDR. If the peripheral device determines to connect with the central device, the peripheral device may disconnect at least one current connection, such as an idle connection, to support establishing a new connection with the central device. In some implementations, the peripheral device may be an example of a Bluetooth basic rate (BR)/enhanced data rate (EDR) device, and the truncated mode may be an example of a truncated page scan mode. In some other implementations, the peripheral device may be an example of a Bluetooth low energy (LE) device, and the truncated mode may be an example of a truncated LE advertising mode. In some examples, the peripheral device may determine whether to connect with the central device based on checking a paired device list (PDL) of the peripheral device for the BD ADDR of the central device.

[0020] 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, by enabling a truncated mode for discovery, the described techniques can be used to allow a peripheral device with multiple established connections to remain discoverable and connectable, even if a quantity of the multiple established connections satisfies (for example, is equal to) the threshold quantity of connections supported by the peripheral device. Additionally, or alternatively, the peripheral device may refrain from occupying any extra memory resources for handling incoming connection requests while operating in the truncated mode (for example, the truncated page scan mode or the truncated advertising mode), improving a memory overhead at the peripheral device. In some implementations, by supporting a truncated page scan mode for BR/EDR devices and a truncated LE advertising mode for LE devices, the described techniques can support alignment between processes for BR/EDR and LE devices. For example, the truncated modes may support a unified way across BR/EDR and LE of indicating an incoming connection request to a host of the peripheral device without occupying resources of a controller of the peripheral device. This may additionally reduce a processing overhead associated with an application of the peripheral device (for example, as compared to handling an actual connection complete event). The techniques described herein may be transparent to the central devices connecting to the peripheral device. Additionally, or alternatively, by determining whether to connect to a central device while operating in the truncated mode for discovery, the peripheral device may support additional flexibility associated wi th maintaining established connections or switching to a different connection based on communication priorities or other rules. In some implementations, by maintaining support for discovery and connection, the peripheral device may improve Bluetooth reliability, connectivity, and latency.

[0021] Figure 1 shows a pictorial diagram of an example wireless communication network 100. According to some aspects, the wireless communication network 100 can be an example of a WLAN such as a Wi-Fi network. For example, the wireless communication network 100 can be a network implementing at least one of the IEEE 802. 11 family of wireless communication protocol standards (such as defined by the IEEE 802. 11-2020 specification or amendments thereof including, but not limited to, 802.11ay, 802.11ax, 802.11az, 802.11ba, 802.11bc, 802.11bd, 802.11be, 802.11bf, and 802. 1 Ibn). In some other examples, the wireless communication network 100 can be an example of a cellular radio access network (RAN), such as a 5G or 6G RAN that implements one or more cellular protocols such as those specified in one or more 3GPP standards. In some other examples, the wireless communication network 100 can include a WLAN that functions in an interoperable or converged manner with one or more cellular RANs to provide greater or enhanced network coverage to wireless communication devices within the wireless communication network 100 or to enable such devices to connect to a cellular network’s core, such as to access the network management capabilities and functionality' offered by the cellular network core. In some other examples, the wireless communication network 100 can include a WLAN that functions in an interoperable or converged manner with one or more personal area networks, such as a network implementing Bluetooth or other wireless technologies, to provide greater or enhanced network coverage or to provide or enable other capabilities, functionality, applications, or services.

[0022] The wireless communication network 100 may include numerous wireless communication devices including at least one wireless access point (AP) 102 and any number of wireless stations (STAs) 104. While only one AP 102 is shown in Figure 1, the wireless communication network 100 can include multiple APs 102. The AP 102 can be or represent various different types of network entities including, but not limited to, a home networking AP. an enterprise-level AP, a single-frequency AP, a dual-band simultaneous (DBS) AP. a tri-band simultaneous (TBS) AP, a standalone AP, a non- standalone AP, a software-enabled AP (soft AP), and a multi -link AP (also referred to as an AP multi-link device (MLD)), as well as cellular (such as 3GPP, 4G LTE, 5G or 6G) base stations or other cellular network nodes such as a Node B. an evolved Node B (eNB), a gNB, a transmission reception point (TRP) or another type of device or equipment included in a radio access network (RAN), including Open-RAN (O-RAN) network entities, such as a central unit (CU), a distributed unit (DU) or a radio unit (RU).

[0023] Each of the STAs 104 also may be referred to as a mobile station (MS), a mobile device, a mobile handset, a wireless handset, an access terminal (AT), a user equipment (UE), a subscriber station (SS), or a subscriber unit, among other examples. The STAs 104 may represent various devices such as mobile phones, other handheld or wearable communication devices, netbooks, notebook computers, tablet computers, laptops, Chromebooks. augmented reality (AR), virtual reality (VR), mixed reality (MR) or extended reality (XR) wireless headsets or other peripheral devices, wireless earbuds, other wearable devices, display devices (for example, TVs, computer monitors or video gaming consoles), video game controllers, navigation systems, music or other audio or stereo devices, remote control devices, printers, kitchen appliances (including smart refrigerators) or other household appliances, key fobs (for example, for passive keyless entry and start (PKES) systems), Internet of Things (loT) devices, and vehicles, among other examples.

[0024] A single AP 102 and an associated set of STAs 104 may be referred to as a basic service set (BSS), which is managed by the respective AP 102. Figure 1 additionally shows an example coverage area 108 of the AP 102, which may represent a basic service area (BSA) of the wireless communication network 100. The BSS may be identified by STAs 104 and other devices by a service set identifier (SSID), as well as a basic sendee set identifier (BSSID), which may be a medium access control (MAC) address of the AP 102. The AP 102 may periodically broadcast beacon frames (“beacons”) including the BSSID to enable any STAs 104 within wireless range of the AP 102 to “associate” or re-associate with the AP 102 to establish a respective communication link 106 (hereinafter also referred to as a “Wi-Fi link”), or to maintain a communication link 106, with the AP 102. For example, the beacons can include an identification or indication of a primary channel used by the respective AP 102 as well as a timing synchronization function (TSF) for establishing or maintaining timing synchronization with the AP 102. The AP 102 may provide access to external networks to various STAs 104 in the wireless communication network 100 via respective communication links 106.

[0025] To establish a communication link 106 with an AP 102, each of the STAs 104 is configured to perform passive or active scanning operations (“scans”) on frequency channels in one or more frequency bands (for example, the 2.4 GHz, 5 GHz, 6 GHz, 45 GHz, or 60 GHz bands). To perform passive scanning, a STA 104 listens for beacons, which are transmitted by respective APs 102 at periodic time intervals referred to as target beacon transmission times (TBTTs). To perform active scanning, a STA 104 generates and sequentially transmits probe requests on each channel to be scanned and listens for probe responses from APs 102. Each STA 104 may identify, determine, ascertain, or select an AP 102 with which to associate in accordance with the scanning information obtained through the passive or active scans, and to perform authentication and association operations to establish a communication link 106 with the selected AP 102. The selected AP 102 assigns an association identifier (AID) to the STA 104 at the culmination of the association operations, which the AP 102 uses to track the STA 104.

[0026] As a result of the increasing ubiquity of wireless networks, a STA 104 may have the opportunity to select one of many BSSs within range of the STA 104 or to select among multiple APs 102 that together form an extended sendee set (ESS) including multiple connected BSSs. For example, the wireless communication network 100 may be connected to a wired or wireless distribution system that may enable multiple APs 102 to be connected in such an ESS. As such, a STA 104 can be covered by more than one AP 102 and can associate with different APs 102 at different times for different transmissions. Additionally, after association with an AP 102, a STA 104 also may periodically scan its surroundings to find a more suitable AP 102 with which to associate. For example, a STA 104 that is moving relative to its associated AP 102 may perform a “roaming” scan to find another AP 102 having more desirable network characteristics such as a greater received signal strength indicator (RS SI) or a reduced traffic load.

[0027] In some examples, STAs 104 may form networks without APs 102 or other equipment other than the STAs 104 themselves. One example of such a network is an ad hoc network (or wireless ad hoc network). Ad hoc networks may alternatively be referred to as mesh networks or peer-to-peer (P2P) networks. In some examples, ad hoc networks may be implemented within a larger network such as the wireless communication network 100. In such examples, while the STAs 104 may be capable of communicating with each other through the AP 102 using communication links 106, STAs 104 also can communicate directly with each other via direct wireless communication links 110. Additionally, two STAs 104 may communicate via a direct wireless communication link 110 regardless of whether both STAs 104 are associated with and served by the same AP 102. In such an ad hoc system, one or more of the STAs 104 may assume the role filled by the AP 102 in a BSS. Such a STA 104 may be referred to as a group owner (GO) and may coordinate transmissions within the ad hoc network. Examples of direct wireless communication links 110 include Wi-Fi Direct connections, connections established by using a Wi-Fi Tunneled Direct Link Setup (TDLS) link, and other P2P group connections.

[0028] In some netw orks, the AP 102 or the STAs 104, or both, may support applications associated with high throughput or low-latency requirements, or may provide lossless audio to one or more other devices. For example, the AP 102 or the STAs 104 may support applications and use cases associated with ultra-low-latency (ULL), such as ULL gaming, or streaming lossless audio and video to one or more personal audio devices (such as peripheral devices) or AR/VR/MR/XR headset devices. In scenarios in which a user uses two or more peripheral devices, the AP 102 or the STAs 104 may support an extended personal audio network enabling communication with the two or more peripheral devices. Additionally, the AP 102 and STAs 104 may support additional ULL applications such as cloud-based applications (such as VR cloud gaming) that have ULL and high throughput requirements.

[0029] As indicated above, in some implementations, the AP 102 and the STAs 104 may function and communicate (via the respective communication links 106) according to one or more of the IEEE 802. 11 family of wireless communication protocol standards. These standards define the WLAN radio and baseband protocols for the physical (PHY) and MAC layers. The AP 102 and STAs 104 transmit and receive wireless communications (hereinafter also referred to as “Wi-Fi communications” or “wireless packets”) to and from one another in the form of PHY protocol data units (PPDUs).

[0030] Each PPDU is a composite structure that includes a PHY preamble and a payload that is in the form of a PHY service data unit (PSDU). The information provided in the preamble may be used by a receiving device to decode the subsequent data in the PSDU. In instances in which a PPDU is transmitted over a bonded or wideband channel, the preamble fields may be duplicated and transmitted in each of multiple component channels. The PHY preamble may include both a legacy portion (or “legacy preamble”) and a non-legacy portion (or “non-legacy preamble”). The legacy preamble may be used for packet detection, automatic gain control and channel estimation, among other uses. The legacy preamble also may generally be used to maintain compatibility' with legacy devices. The format of, coding of, and information provided in the non-legacy portion of the preamble is associated with the particular IEEE 802. 11 wireless communication protocol to be used to transmit the payload.

[0031] In some implementations, the wireless communication network 100 may support Bluetooth communications. For example, the STAs 104 may be examples of wireless communication devices supporting Bluetooth operations. The STAs 104 may be examples of central devices (such as source devices) or may be examples of peripheral devices (such as sink devices) implementing WLAN communications (such as Wi-Fi communications) or Bluetooth communications. For example, central devices may include cell phones, UEs, wireless STAs, mobile stations, personal digital assistant (PDAs), other handheld devices, netbooks, notebook computers, tablet computers, laptops, broadcaster audio devices, or some other suitable terminology. Peripheral devices may include Bluetooth-enabled devices capable of pairing with other Bluetooth- enabled devices (such as central devices) or otherwise receiving unicast or broadcast Bluetooth communication and may include wireless audio devices (such as headsets, earbuds, speakers, earpieces, or headphones), display devices (such as TVs, glasses, or computer monitors), microphones, meters, or valves.

[0032] Bluetooth communications may refer to a short-range communication protocol and may be used to connect and exchange information between central devices and peripheral devices (such as between mobile phones, computers, digital cameras, wireless headsets, speakers, keyboards, mice or other input peripherals, and similar devices). Bluetooth systems (such as aspects of wireless communication network 100) may be organized using a central-peripheral relationship employing a time-division duplex protocol having, for example, defined time slots of 625 microseconds, in which transmission alternates between the central device (such as a source device) and one or more peripheral devices (such as sink devices). As such, in some examples, a device may be referred to as either a central device or a peripheral device based on the Bluetooth role configuration of the device. That is, designation of a device as either a central device or a peripheral device may not necessarily indicate a distinction in device capability, but rather may refer to or indicate roles held by the device in the wireless communication network 100. Generally, a central device may refer to a wireless communication device capable of wirelessly exchanging data signals with another device (such as a peripheral device), and a peripheral device may refer to a device operating in a peripheral role, or to a short-range wireless communication device capable of exchanging data signals with the central device (for example, using Bluetooth communication protocols).

[0033] A Bluetooth-enabled device may be compatible with certain Bluetooth profiles to use desired services. A Bluetooth profile may refer to a specification regarding an aspect of Bluetooth-based wireless communications between devices. That is, a profile specification may refer to a set of instructions for using the Bluetooth protocol stack in a certain way, and may include information such as suggested user interface formats or particular options and parameters at each layer of the Bluetooth protocol stack. For example, a Bluetooth specification may include various profiles that define the behavior associated with each communication endpoint to implement a specific use case. Profiles may thus generally be defined according to a protocol stack that promotes and allows interoperability⁷ between endpoint devices from different manufacturers through enabling applications to discover and use services that other nearby Bluetooth-enabled devices may be offering. The Bluetooth specification defines device role pairs (such as roles for a central device and a peripheral device) that together form a single use case called a profile (such as for communications between the central device and the peripheral device). One example profile defined in the Bluetooth specification is the Handsfree Profile (HFP) for voice telephony, in which one device (such as a central device) implements an Audio Gateway (AG) role and the other device (such as a peripheral device) implements a Handsfree (HF) device role. Another example is the Advanced Audio Distribution Profile (A2DP) for high-quality audio streaming, in which one device (such as central device) implements an audio source device (SRC) role and another device (such as peripheral device) implements an audio sink device (SNK) role.

[0034] For a commercial Bluetooth-enabled device that implements one role in a profile to function properly, another device that implements the corresponding role may be present within the radio range of the first device. For example, in order for an HF device such as a Bluetooth headset to function according to the Handsfree Profile, a device implementing the AG role (such as a cell phone) may have to be present within radio range. Likewise, in order to stream high-quality' mono or stereo audio according to the A2DP, a device implementing the SNK role (such as Bluetooth headphones or Bluetooth speakers) may have to be within radio range of a device implementing the SRC role (such as a stereo music player).

[0035] The Bluetooth specification defines a layered data transport architecture and various protocols and procedures to handle data communicated between two devices that implement a particular profile use case. For example, various logical links are available to support different application data transport requirements, with each logical link associated with a logical transport having certain characteristics (such as flow control, acknowledgement mechanisms, repeat mechanisms, sequence numbering, or scheduling behavior. The Bluetooth protocol stack may be split in two parts: a controller stack including the timing critical radio interface, and a host stack handling high level data. The controller stack may be generally implemented in a low cost silicon device including one or more Bluetooth radios and one or more microprocessors. The controller stack may be responsible for setting up direct wireless communication links 110 such as asynchronous connection-less (ACL) links, (or ACL connections), synchronous connection orientated (SCO) links (or SCO connections), extended synchronous connection-oriented (eSCO) links (or eSCO connections), broadcast isochronous streams (BISs), connected isochronous streams (CISs), or other logical transport channel links.

[0036] In some examples, the controller stack may implement link management protocol (LMP) functions or low energy link layer (LELL) functions. The host stack may be generally implemented as part of an operating system, or as an installable package on top of an operating system. The host stack may be responsible for logical link control and adaptation protocol (L2CAP) functions, Bluetooth network encapsulation protocol (BNEP) functions, or service discovery protocol (SDP) functions. In some examples, the controller stack and the host stack may communicate via a host controller interface (HCI). In some other examples, (such as for integrated devices such as Bluetooth headsets), the host stack and controller stack may be run on the same microprocessor to reduce mass production costs. For such host-less systems, the HCI may be optional, and may be implemented as an internal software interface.

[0037] A direct wireless communication link 110 may be established between two Bluetooth-enabled devices (such as between a central device and a peripheral device) and may provide for communications or sendees (such as according to some Bluetooth profile). For example, a Bluetooth connection may be an eSCO connection for voice call (such as which may allow for retransmission) or an ACL connection for music streaming (such as A2DP), among other examples. For example, eSCO packets may be transmitted in predetermined time slots (such as 6 Bluetooth slots each for eSCO). The regular interval between the eSCO packets may be specified when the Bluetooth link is established. The eSCO packets to/from a specific peripheral device (such as a peripheral device) are acknowledged, and may be retransmitted if not acknowledged during a retransmission window. In addition, audio may be streamed between a central device and a peripheral device using an ACL connection (A2DP profile). In some examples, the ACL connection may occupy 1. 3, or 5 Bluetooth slots for data or voice. Other Bluetooth profiles supported by Bluetooth-enabled devices may include Bluetooth Low Energy (BLE) (such as providing considerably reduced power consumption and cost while maintaining a similar communication range) or human interface device profile (HID) (such as providing low latency links with low power requirements).

[0038] A device may, in some examples, be capable of both Bluetooth and WLAN communications. For example, WLAN and Bluetooth components may be co-located within a device, such that the device may be capable of communicating according to both Bluetooth and WLAN communication protocols, as each technology may offer different benefits or may improve user experience in different conditions. In some examples, Bluetooth and WLAN communications may share a same medium, such as the same unlicensed frequency medium. In such examples, a central device may support WLAN communications via an AP 102 (such as over communication links 106). The AP 102 and the associated central devices may represent a basic service set (BSS) or an extended service set (ESS). The various central devices in the network may be able to communicate with one another through the AP 102. In some examples, the AP 102 may be associated with a coverage area 108, which may represent a basic service area (BSA).

[0039] In some examples, content, media, or audio exchanged between a central device and a peripheral device may originate from a WLAN. For example, in some examples, a central device may receive audio from an AP 102 (such as via WLAN communications), and the central device may relay or pass the audio to the peripheral device (such as via Bluetooth communications). In some examples, certain types of Bluetooth communications (such as such as high quality or high definition (HD) Bluetooth) may require enhanced quality of service (QoS). In some examples, delaysensitive Bluetooth traffic may have higher priority than WLAN traffic.

[0040] The APs 102 and STAs 104 in the wireless communication netw ork 100 may transmit PPDUs over an unlicensed spectrum, such as the 2.4 GHz, 5 GHz, 6 GHz. 45 GHz. and 60 GHz bands. Some examples of the APs 102 and STAs 104 described herein also may communicate in other frequency bands that may support licensed or unlicensed communications. For example, the APs 102 or STAs 104, or both, also may be capable of communicating over licensed operating bands, where multiple operators may have respective licenses to operate in the same or overlapping frequency ranges. Such licensed operating bands may map to or be associated with frequency range designations of FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7. 125 GHz - 24.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). In some networks, Bluetooth communication may use the 2.4 GHz spectrum band, which may refer to a spectrum band of 2,400 MHz - 2,483.5 MHz.

[0041] Each of the frequency bands may include multiple sub-bands and frequency channels (also referred to as subchannels). The terms “channef’ and ‘‘subchannel” may be used interchangeably herein, as each may refer to a portion of frequency spectrum within a frequency band (for example, a 20 MHz, 40 MHz, 80 MHz, or 160 MHz portion of frequency spectrum) via which communication between two or more wireless communication devices can occur. For example, PPDUs may be transmitted over one or more of the 2.4 GHz, 5 GHz, or 6 GHz bands, each of which is divided into multiple channels (such as 1 MHz channels or 2 MHz channels for Bluetooth communication). An AP 102 may determine or select an operating or operational bandwidth for the ST As 104 and select a range of channels within a band to provide that operating bandwidth. In some aspects, Bluetooth communication may divide transmitted data into packets and may transmit each packet on one of 79 designated Bluetooth channels. Each channel may have a bandwidth of 1 MHz. A Bluetooth device may perform a quantity of hops per second, which may refer to how the Bluetooth device switches from transmitting via a first channel to transmitting via a second channel. In some aspects, a Bluetooth device may perform approximately 1.600 hops per second, with adaptive frequency-hopping (AFH) enabled. BLE may use 2 MHz spacing, which may accommodate 40 channels.

[0042] Some Bluetooth devices, which may be examples of STAs 104, may support multipoint connections. For example, a Bluetooth device may connect (for example, establish a wireless communication link, such as a direct wireless communication link 110) with multiple other Bluetooth devices (e.g., multiple other STAs 104) concurrently. In some implementations, a Bluetooth device, such as an earbud or another type of device, may operate as a peripheral device for multiple Bluetooth connections (for example, connecting to different central devices). The Bluetooth device may support up to a threshold quantity of Bluetooth connections concurrently. For example, each connection may use a set of resources (e.g., frequency resources, time resources) to support communications. To establish a connection, the Bluetooth device may allocate the set of resources for the connection. However, the Bluetooth device may fail to support additional connections beyond the threshold uantity of Bluetooth connections, for example, based on resource availability at the Bluetooth device, scheduling conflicts at the Bluetooth device, or both. For example, the frequency resources available to the Bluetooth device may not support allocating resources for an additional connection beyond the threshold quantity of Bluetooth connections (e.g., when accounting for bandwidth thresholds, bandwidth buffers, frequency hopping). Accordingly, if the Bluetooth device currently operates with the threshold quantity of connections, the Bluetooth device may fail to support connecting with an additional device.

[0043] However, the wireless communication network 100 may expect each Bluetooth device within the network to be discoverable and connectable. For example, maintaining the Bluetooth device as discoverable and connectable may improve the flexibility of the network, the reliability of Bluetooth communications, or both. To support the Bluetooth device remaining discoverable and connectable despite operating with the threshold quantity of connections, the Bluetooth device may enable a truncated mode for discovery. For example, a device operating according to Bluetooth basic rate (BR)/enhanced data rate (EDR) transport may support a truncated page scan mode, and a device operating according to Bluetooth low energy (LE) transport may support a truncated advertising mode. The truncated mode may allow the Bluetooth device to determine if another device (for example, another Bluetooth device operating as a central device) is requesting, or otherwise attempting, to connect to the Bluetooth device. The Bluetooth device may halt the discovery and connection process before connecting with the other device to avoid resource allocation and scheduling conflicts associated with adding a connection exceeding the threshold quantity of connections. Instead, the Bluetooth device may first disconnect one or more existing connections (for example, wireless communication links, such as direct wireless communication links 110) before adding the connection to the other device. Accordingly, the truncated mode may support Bluetooth devices that are currently operating with the threshold quantity of connections being discoverable and connectable without violating (for example, exceeding) the threshold quantity of connections.

[0044] Figure 2 shows an example of a signaling diagram that supports barge-in multipoint connections. For example, a wireless communications system 200 may support the signaling of the signaling diagram. The wireless communications system 200 may include a first wireless communication device 202-a, a second wireless communication device 202-b, a third wireless communication device 202-c, a fourth wireless communication device 202-d, and a fifth wireless communication device 202-e. Each of the wireless communication devices may support Bluetooth communications. In some examples, the wireless communication devices may be examples of STAs 104, as described herein with reference to Figure 1. The first wireless communication device 202-a may operate as a peripheral device for multiple wireless communication links (for example, connections). For example, the first wireless communication device 202-a may be an example of a BR/EDR Bluetooth device operating with multipoint connections or an LE Bluetooth device operating with multipoint connections. The first wireless communication device 202-a may enable a truncated mode for discovery to support “barge-in” multipoint connections. “Barge-in” multipoint connections may refer to a device discovering and connecting with the first wireless communication device 202-a despite the first wireless communication device 202-a already having multipoint connections (such as a threshold quantity of connections) with multiple other devices.

[0045] In some implementations, the first wireless communication device 202-a may be an example of an earbud operating as a primary earbud. For example, for Bluetooth audio communications with two earbuds implementing an advanced audio distribution profile (A2DP) mirroring topology, one earbud (the primary) may connect to a source device (for example, a phone, a laptop, or some other STA 104) to receive the audio data from the source device. The primary' earbud may decode the audio data, and the other earbud (the secondary) may connect to the primary earbud to mirror, or otherwise use, the audio data received and decoded at the primary earbud. The primary and secondary earbuds may transit audio signals based on the received and decoded audio data.

[0046] As an example network topology⁷, the first w ireless communication device 202-a (for example, the primary earbud) may connect to a second w ireless communication device 202-b (for example, a phone or other STA 104). a fourth wireless communication device 202-d (for example, another phone or other STA 104), and a fifth wireless communication device 202-e (for example, a secondary⁷ earbud). For example, the first wireless communication device 202-a may establish multiple wireless communication links, including a first wireless communication link 204-a with the second wireless communication device 202-b, a second wireless communication link 204-b with the fourth wireless communication device 202-d, and a third w ireless communication link 204-c with the fifth wireless communication device 202-e. The first wireless communication device 202-a may operate as a peripheral device to the second wireless communication device 202-b operating as a central device. However, the second wireless communication device 202-b may be currently non-streaming to the first wireless communication device 202-a, such that the first wireless communication link 204-a is currently idle. The first wireless communication device 202-a may also operate as a peripheral device to the fourth wireless communication device 202-d operating as a central device. However, the fourth wireless communication device 202-d may be currently streaming data (for example, audio data) to the first wireless communication device 202-a, such that the second wireless communication link 204-b is currently active or otherwise non-idle. In some examples, the first wireless communication device 202-a may additionally operate as a peripheral device to the fifth wireless communication device 202-e operating as a central device. For example, if the first wireless communication device 202-a and the fifth wireless communication device 202-e are examples of a pair of earbuds with a shared charging case, the first wireless communication device 202-a may be pulled out of the charging cast first and connect to one or more devices as a primary earbud. Subsequently, the fifth wireless communication device 202-e may be pulled out of the charging case and may connect to the primary earbud as a secondary earbud. In such an example, the secondary earbud may operate as a central device to the primary earbud (a peripheral device). In some implementations, the wireless communications system 200 may support role switching between earbuds to improve connectivity and audio quality. For example, the pair of earbuds may transparently switch which earbud operates as the primary' and which earbud operates as the secondary . The techniques described herein may apply to any Bluetooth devices operating as peripherals, including either earbud if role switching is supported. In some other implementations, the primary and secondary earbuds may refrain from performing role switching based on one or more A2DP parameters.

[0047] The first wireless communication device 202-a may support a threshold quantity' of communication links concurrently in a multipoint connection configuration. For example, based on scheduling availability, resource availability, periodic or nonperiodic clashes, or any combination thereof, the first wireless communication device 202-a may support up to a threshold quantity⁷ of communication links concurrently. In some examples, the threshold quantity of communication links may be an example of a threshold quantity of total communication links at the first wireless communication device 202-a, a threshold quantity of peripheral communication links at the first wireless communication device 202-a, a threshold quantity of communication links to source devices (for example, phones, laptops, or other source devices of data), a threshold quantity of connections, a threshold quantity of resources allocated for connections, or any combination of these or other thresholds associated with a quantity of communication links supported at the first wireless communication device 202-a. In some implementations, an LE Bluetooth device may support one or more LE Isochronous (ISO) channels, and the device may support a threshold quantity of connections including LE ISO links and standard LE links or may support a threshold quantity of standard LE connections. In some examples, different devices may support different threshold quantities of connections, for example, based on one or more parameters or capabilities of the devices.

[0048] For example, as illustrated, the first wireless communication device 202-a may establish three total connections, which may include two connections to source devices (such as the second wireless communication device 202-b and the fourth wireless communication device 202-d) and one connection to a secondary earbud (such as the wireless communication device 202-e). In some examples, the first wireless communication device 202-a may support a threshold quantity of 3 total connections. Additionally, or alternatively, the first wireless communication device 202-a may support a threshold quantity of 2 source connections (such as connections to phones or other source devices). The first wireless communication device 202-a may be operating with a quantity of connection satisfying (for example, equal to) the threshold quantity of connections for the first wireless communication device 202-a.

[0049] A third wireless communication device 202-c may perform a discovery procedure to discover and connect to an available Bluetooth device (such as the first wireless communication device 202-a). In some other systems, a Bluetooth device (for example, an application of the Bluetooth device) may disable discovery and connection techniques if the Bluetooth device is already operating with the threshold quantity of connections (for example, a maximum supported quantity of connections). For example, the Bluetooth device may disable page scans or advertising, such that the Bluetooth device is not discoverable by other devices. Accordingly, another device performing a discovery procedure may fail to discover the Bluetooth device, potentially impacting the latency and reliability of Bluetooth communications in such other systems.

[0050] In contrast, the wireless communications system 200 may support a truncated mode for discovery' at the first wireless communication device 202-a. such that the first wireless communication device 202-a may remain discoverable and connectable even if the first wireless communication device 202-a is currently operating with multiple communication links (for example, with the threshold quantity of communication links). The truncated mode may enable the first wireless communication device 202-a to perform page scans or advertising when the first wireless communication device 202-a does not support establishing an additional communication link (for example, a fourth peripheral connection with the third wireless communication device 202-c, which the first wireless communication device 202-a may not support due to scheduling availability, resource, such as bandwidth, availability, or both). The first wireless communication device 202-a may refrain from disabling page scans or advertising. The third wireless communication device 202-c may discover and connect with the first wireless communication device 202-a based on the truncated mode for discovery.

[0051] In some examples, the first wireless communication device 202-a may establish multiple communication links with multiple wireless communication devices. The first wireless communication device 202-a may enable the truncated mode for discovery' based on a quantity of the multiple communication links satisfying (for example, being equal to) the threshold quantity of communication links for the first wireless communication device 202-a. The multiple communication links may include at least a first wireless communication link 204-a corresponding to an idle connection with a second wireless communication device 202 -b. In some implementations, the second wireless communication link 204-b may be active, with the fourth wireless communication device 202-d currently streaming data to the first wireless communication device 202-a, and the second wireless communication device 202-b currently not streaming data to the first wireless communication device 202-a. In some other implementations, the second wireless communication link 204-b may also be idle (for example, the first wireless communication device 202-a may have one or more idle connections corresponding to the multiple communication links. [0052] The first wireless communication device 202-a may receive, from a third wireless communication device 202-c, a packet for discovery including an identifier of the third wireless communication device 202-c. For example, the packet may include a BD ADDR 210 corresponding to, or otherwise indicating, the third wireless communication device 202-c. The first wireless communication device 202-a may determine whether to disconnect one or more current wireless communication links and establish a wireless communication link with the third wireless communication device 202-c based on the BD_ADDR 210 of the third wireless communication device 202-c. In some examples, the first wireless communication device 202-a may determine whether to establish the wireless communication link with the third wireless communication device 202-c based on a priority level associated with the third wireless communication device 202-c, a priority level associated with communications at the third wireless communication device 202-c or at the first wireless communication device 202-a, whether a paired device list (PDL) at the first wireless communication device 202-a includes the BD_ADDR 210 of the third wireless communication device 202-c, or any combination of these or other rules or parameters for determining whether to disconnect a connection in order to connect with the third wireless communication device 202-c. In some examples, disconnecting a connection in order to connect with the third wireless communication device 202-c may be referred to as allowing the third wireless communication device 202-c to “barge-in” to the multipoint connection of the first wireless communication device 202-a.

[0053] If the first wireless communication device 202-a determines to connect with the third wireless communication device 202-c, the first wireless communication device 202-a may disconnect a wireless communication link corresponding to a currently idle connection. For example, the first wireless communication device 202-a may disconnect the first wireless communication link 204-a corresponding to the idle connection based on the BD ADDR 210 of the third wireless communication device 202-c and the quantity of the multiple communication links satisfying the threshold quantity of communication links for the first wireless communication device 202-a. In some examples, the first wireless communication device 202-a may disconnect multiple idle connections. Disconnecting at least one idle connection may reduce the quantity of current connections at the first wireless communication device 202-a below the threshold quantity of communication links, releasing enough resources to support allocated resources for an additional wireless communication link. The first wireless communication device 202-a may establish the additional wireless communication link with the third wireless communication device 202-c based on disconnecting the first wireless communication link 204-a.

[0054] In some implementations, the first wireless communication device 202-a may be an example of a BR/EDR Bluetooth device. The BR/EDR Bluetooth device may support discovery and connection using page scans. For example, the first wireless communication device 202-a may enable page scans in a special mode if the first wireless communication device 202-a has the threshold quantity of connections (for example, has two wireless links to a first phone and a second phone). The special mode may be referred to as “Truncated Page Scans” mode or some similar terminology⁷. The first wireless communication device 202-a may refrain from allocating resources of the Bluetooth baseband resources for truncated page scans.

[0055] In the “Truncated Page Scans” mode, the first wireless communication device 202-a may monitor for pages from other devices (for example, similar to a procedure for performing normal page scans). For example, the first wireless communication device 202-a operating as a peripheral device may periodically (or non- periodically) enter a page scan state and monitor for pages from a central device. The third wireless communication device 202-c may⁷ transmit a paging packet for the first wireless communication device 202-a. In some examples, the third wireless communication device 202-c and the first wireless communication device 202-a may exchange identity⁷ (ID) packets. The third wireless communication device 202-c maytransmit an FHS packet 206 to the first wireless communication device 202-a. The FHS packet 206 may include an indication of a BD ADDR 210 corresponding to the third wireless communication device 202-c. Instead of responding to the FHS packet 206 with another ID packet, the first wireless communication device 202-a may refrain from transmitting a response to the FHS packet 206. For example, the response to the FHS packet 206 may confirm connection to the third wireless communication device 202-c, allocate resources for the connection, or both. Refraining from responding to the FHS packet 206 may ensure the first wireless communication device 202-a satisfies (for example, does not exceed or otherwise violate) the threshold quantity of connections supported by the first wireless communication device 202-a. The third wireless communication device 202-c may monitor for, and fail to receive, the response to the FHS packet 206, resulting in a page response timeout (pagerespTO) at both the third wireless communication device 202-c and the first wireless communication device 202-a. The connection between the first wireless communication device 202-a and the third wireless communication device 202-c may fail based on the pagerespTO. In some examples, the first wireless communication device 202-a may continue performing page scans and the third wireless communication device 202-c may continue paging based on the pagerespTO.

[0056] The first wireless communication device 202-a receiving the FHS packet 206 indicating the BD_ADDR 210 of the third wireless communication device 202-c during the truncated page scanning procedure may determine whether to establish a connection with the third wireless communication device 202-c. For example, the first wireless communication device 202-a may check whether a PDL of the first wireless communication device 202-a includes the BD_ADDR 210 of the third wireless communication device 202-c. If the first wireless communication device 202-a determines to connect to the third wireless communication device 202-c, the first wireless communication device 202-a may determine to disconnect at least one current connection (for example, an idle connection). In some examples, a controller or host of the first wireless communication device 202-a may send a notification (for example, a vendor-specific event) to an application of the first wireless communication device 202-a with the BD_ADDR 210 of the third wireless communication device 202-c indicating a desire for a connection between the first wireless communication device 202-a and the third wireless communication device 202-c. Based on the notification (for example, the vendor-specific event), the application may perform a call to disconnect at least one existing connection (for example, an existing wireless communication link with a phone, such as the wireless communication link 204-a with the second wireless communication device 202-b). In some examples, the application may check the PDL to confirm that the third wireless communication device 202-c is included within the PDL. The application may perform a call to disconnect the wireless communication link 204-a corresponding to an idle connection with the second wireless communication device 202-b. [0057] Based on the first wireless communication device 202-a disconnecting the first wireless communication link 204-a, the first wireless communication device 202-a may disable the special mode (for example, the ‘‘Truncated Page Scans” mode). For example, the first wireless communication device 202-a may revert to, or otherwise reenable, a normal page scan mode based on the quantity of connections at the first wireless communication device 202-a not satisfying (such as being less than) the threshold quantity of connections supported by the first wireless communication device 202-a.

[0058] In the normal page scan mode, the first wireless communication device 202-a may receive a paging packet from the third wireless communication device 202-c and perform a full discovery and connection process. For example, the first wireless communication device 202-a and the third wireless communication device 202-c may exchange ID packets, and the third wireless communication device 202-c may transmit another FHS packet 206 to the first wireless communication device 202-a. Because the first wireless communication device 202-a is operating according to the normal page scan mode, the first wireless communication device 202-a may respond to the FHS packet 206 with an ID packet. Based on the response, the first wireless communication device 202-a may allocate resources for a connection and may establish the connection with the third wireless communication device 202-c. The new connection (for example, an additional wireless communication link) between the first wireless communication device 202-a and the third wireless communication device 202-c may be an idle connection or an active connection (such as a streaming connection), for example, based on whether the third wireless communication device 202-c streams data to the first wireless communication device 202-a.

[0059] In some other implementations, the first wireless communication device 202-a may be an example of an LE Bluetooth device. The LE Bluetooth device may support discovery and connection using advertising. For example, the first wireless communication device 202-a may enable connectable LE advertising in a special mode if the first wireless communication device 202-a has the threshold quantity of connections (for example, has two wireless links to a first phone and a second phone). The special mode may be referred to as “Truncated LE Advertising” mode or some similar terminology. The first wireless communication device 202-a may refrain from allocating resources (for example, Bluetooth baseband resources, LE resources) for truncated LE advertising.

[0060] In the “Truncated LE Advertising” mode, the first wireless communication device 202-a may transmit advertising indication (ADV_IND) packets (for example, similar to a procedure for performing normal LE advertising). For example, the first wireless communication device 202-a operating as a peripheral device may periodically (or non-periodically) transmit ADV_IND packets and monitor for connection request packets 208 in response. The third wireless communication device 202-c may receive an ADV_IND packet indicating the first wireless communication device 202-a as an advertiser (for example, advertising the first wireless communication device 202-a operating as a Bluetooth peripheral device), and the third wireless communication device 202-c may transmit a connection request packet 208 to trigger a connection to the first wireless communication device 202-a. The connection request packet 208 may include an indication of a BD ADDR 210 corresponding to the third wireless communication device 202-c. In some examples, the connection request packet 208 may be an example of a connection indicator (CONNECT_IND) packet. In some other examples, the connection request packet 208 may be an example of an auxiliary' connection request (AUX CONNECT REQ) packet. The first wireless communication device 202-a receiving the connection request packet 208 may identify the BD_ADDR 210 of the third wireless communication device 202-c, but may otherwise refrain from processing one or more portions of the connection request packet 208 to refrain from accepting or otherwise establishing a connection with the third wireless communication device 202-c. By refraining from establishing the connection, the first wireless communication device 202-a may refrain from exceeding, or otherwise violating, the threshold quantify of connections supported by the first wireless communication device 202-a. If the first wireless communication device 202-a receives a CONNECT_IND packet indicating one or more channels for the connection, the first wireless communication device 202-a may refrain from monitoring the indicated one or more channels for a POLL packet, a NULL packet, or a combination thereof from the third wireless communication device 202-c. If the first wireless communication device 202-a receives an AUX_CONNECT_REQ packet, the first wireless communication device 202-a may refrain from transmitting an auxiliary' connection response (AUX_CONNECT_RSP) packet in response. The first wireless communication device 202-a refraining from completing the connection process while operating in the “Truncated LE Advertising’" mode may cause a “connection failed to establish"’ event at the third wireless communication device 202-c. In some examples, the first wireless communication device 202-a may continue performing advertising and the third wireless communication device 202-c may continue monitoring for advertising and requesting connections based on failing to establish the connection.

[0061] The first wireless communication device 202-a receiving the connection request packet 208 indicating the BD ADDR 210 of the third wireless communication device 202-c during the truncated LE advertising procedure may determine whether to establish a connection with the third wireless communication device 202-c. For example, the first wireless communication device 202-a may check whether a PDL of the first wireless communication device 202-a includes the BD_ADDR 210 of the third wireless communication device 202-c. If the first wireless communication device 202-a determines to connect to the third wireless communication device 202-c, the first wireless communication device 202-a may determine to disconnect at least one current connection (for example, an idle connection). In some examples, a controller or host of the first wireless communication device 202-a may send a notification (for example, a vendor-specific event) to an application of the first wireless communication device 202-a with the BD_ADDR 210 of the third wireless communication device 202-c indicating a desire for a connection between the first wireless communication device 202-a and the third wireless communication device 202-c. Based on the notification (for example, the vendor-specific event), the application may perform a call to disconnect at least one existing connection (for example, an existing wireless communication link with a phone, such as the wireless communication link 204-a with the second wireless communication device 202-b). In some examples, the application may check the PDL to confirm that the third wireless communication device 202-c is included within the PDL. The application may perform a call to disconnect the wireless communication link 204-a corresponding to an idle connection with the second wireless communication device 202-b.

[0062] Based on the first wireless communication device 202-a disconnecting the first wireless communication link 204-a. the first wireless communication device 202-a may disable the special mode (for example, the “Truncated LE Advertising” mode). For example, the first wireless communication device 202-a may revert to, or otherwise re-enable, a normal LE advertising mode based on the quantity of connections at the first wireless communication device 202-a not satisfying (such as being less than) the threshold quantity of connections supported by the first wireless communication device 202-a.

[0063] In the normal LE advertising mode, the first wireless communication device 202-a may transmit an ADV_IND packet and perform a full discovery' and connection process with the third wireless communication device 202-c. For example, the first wireless communication device 202-a may transmit the ADV_IND packet. The third wireless communication device 202-c may receive the ADV_IND packet and transmit another connection request packet 208 to the first wireless communication device 202-a. Because the first wireless communication device 202-a is operating according to the normal LE advertising mode, the first wireless communication device 202-a may process the connection request packet 208. For example, if the connection request packet 208 is a CONNECT_IND, the first wireless communication device 202-a may switch to monitor the indicated connection channels for a POLL packet, a NULL packet, or a combination thereof from the third wireless communication device 202-c. If the connection request packet 208 is an AUX_CONNECT_REQ packet, the first wireless communication device 202-a may transmit an AUX_CONNECT_RSP packet in response. The first wireless communication device 202-a may allocate resources for a connection and may establish the connection (for example, an LE connection) with the third wireless communication device 202-c based on processing the connection request packet 208 and completing the discovery and connection process. The new' connection (for example, an additional w ireless communication link) between the first wireless communication device 202-a and the third w ireless communication device 202-c may be an idle connection or an active connection (such as a streaming connection), for example, based on whether the third wireless communication device 202-c streams data to the first wireless communication device 202-a.

[0064] Figures 3A, 3B, and 3C show example timelines of signaling in truncated modes that support barge-in multipoint connections. Figure 3A shows an example timeline of signaling for a central device 304-a communicating with a peripheral device 302-a operating according to a truncated page scan mode. The peripheral device 302-a may be an example of any Bluetooth-capable device, such as an earbud (for example, a primary earbud), a wireless communication device 202-a as described herein with reference to Figure 2, or a STA 104 as described herein with reference to Figure 1. The central device 304-a may be an example of any Bluetooth-capable device, such as a source device for audio data (for example, a phone or laptop), a wireless communication device 202-c as described herein with reference to Figure 2, or a STA 104 as described herein with reference to Figure 1. The peripheral device 302-a may enable and operate according to a truncated page scan mode based on the peripheral device 302-a currently operating with a quantity of connections satisfying a threshold quantity of connections for the peripheral device 302-a.

[0065] For example, the peripheral device 302-a may perform page scans and the central device 304-a may perform paging operations. The central device 304-a may transmit a first ID packet 306-a, and the peripheral device 302-a may receive the first ID packet 306-a and determine that a relatively nearby Bluetooth device is performing paging to discovery an available peripheral device. The peripheral device 302-a may transmit a second ID packet 306-b in response to the first ID packet 306-a to indicate that there is a nearby Bluetooth peripheral device. Accordingly, the peripheral device 302-a supports the central device 304-a discovering the peripheral device 302-a via the truncated page scans.

[0066] The central device 304-a may transmit an FHS packet 308 to the peripheral device 302-a to request a connection with the peripheral device 302-a. The FHS packet 308 may indicate one or more parameters associated with the requested connection, such as an FHS pattern, the BD ADDR of the central device 304-a, or some combination of these and other connection parameters. The central device 304-a may monitor for a third ID packet 306-c in response, where the third ID packet 306-c may confirm that the peripheral device 302-a will connect with the central device 304-a according to the connection parameters indicated by the FHS packet 308. However, based on operating in the truncated page scan mode, the peripheral device 302-a may refrain from transmitting the ID packet 306-c (for example, an ID packet in response to the FHS packet 308). The central device 304-a may monitor for the ID packet 306-c for a threshold time period corresponding to a pagerespTO. If the threshold time period expires without the central device 304-a receiving the ID packet 306-c, the central device 304-a may determine that the connection process timed out and may perform additional paging to discover and connect with another peripheral device (or with the peripheral device 302-a after the peripheral device 302-a disconnects at least one connection). The peripheral device 302-a may similarly determine a pagerespTO based on not responding to the FHS packet 308 (for example, not responding within a threshold time period corresponding to the pagerespTO) and may perform additional page scans. The peripheral device 302-a may additionally determine whether to disconnect a current connection to allow for connection with the central device 304-a based on the BD ADDR of the central device 304-a.

[0067] Figure 3B shows an example timeline of signaling for a central device 304-b communicating with a peripheral device 302-b operating according to a truncated advertising mode, for example, supporting legacy advertising operations. The peripheral device 302-b may be an example of any Bluetooth-capable device, such as an earbud (for example, a primary earbud), a wireless communication device 202-a as described herein with reference to Figure 2, or a STA 104 as described herein with reference to Figure 1. The central device 304-b may be an example of any Bluetooth- capable device, such as a source device for audio data (for example, a phone or laptop), a wireless communication device 202-c as described herein with reference to Figure 2, or a STA 104 as described herein with reference to Figure 1. The peripheral device 302-b may enable and operate according to a truncated advertising mode based on the peripheral device 302-b currently operating with a quantity of connections satisfying a threshold quantity of connections for the peripheral device 302-b.

[0068] For example, the peripheral device 302-b may perform advertising and the central device 304-b may trigger a connection to the advertiser. The peripheral device 302-b may transmit an ADV_IND packet 310-a to advertise that the peripheral device 302-b supports peripheral LE connections. The central device 304-b may receive the ADV_IND packet 310-a, determine the existence of a relatively nearby Bluetooth device advertising LE peripheral connections, and may determine to connect to the peripheral device 302-b. The central device 304-b may transmit a CONNECT_IND packet 312 indicating one or more connection parameters to the peripheral device 302-b. The central device 304-b may perform one or more connection events to attempt to connect with the peripheral device 302-b according to the one or more connection parameters. However, based on operating in the truncated advertising mode, the peripheral device 302-b may refrain from completing a connection event. For example, the central device 304-b may indicate, in the CONNECT_IND packet 312, a channel or other resources for the peripheral device 302-b to use for the connection. The central device 304-b may transmit a POLL packet, a NULL packet, or both via the channel or other resources to the peripheral device 302-b. However, the peripheral device 302-b may refrain from monitoring the channel or other resources for the POLL packet, the NULL packet, or both based on the enabled truncated advertising mode. Accordingly, the peripheral device 302-b may fail to complete the connection with the central device 304-b based on the peripheral device 302-b failing to receive the POLL/NULL transmission 314. In some examples, the central device 304-b may repeat the POLL/NULL transmission 314 a threshold quantity of times before determining that the connection failed. For example, the central device 304-b, the peripheral device 302-b, or both may determine that the connection failed to be established after six unsuccessful connection events (for example, six unsuccessful POLL/NULL transmissions 314).

[0069] If the connection fails to establish, the central device 304-b may perform additional monitoring for advertising to discover and connect with another peripheral device (or with the peripheral device 302-b after the peripheral device 302-b disconnects at least one connection). The peripheral device 302-b may similarly perform further advertising. The peripheral device 302-b may additionally determine whether to disconnect a current connection to allow for connection with the central device 304-b based on the BD_ADDR of the central device 304-b indicated by the CONNECT IND packet 312.

[0070] Figure 3C shows an example timeline of signaling for a central device 304-c communicating with a peripheral device 302-c operating according to a truncated advertising mode. The peripheral device 302-c may be an example of any Bluetooth- capable device, such as an earbud (for example, a primary earbud), a wireless communication device 202-a as described herein with reference to Figure 2, or a STA 104 as described herein with reference to Figure 1. The central device 304-c may be an example of any Bluetooth-capable device, such as a source device for audio data (for example, a phone or laptop), a wireless communication device 202-c as described herein with reference to Figure 2, or a STA 104 as described herein with reference to Figure 1 . The peripheral device 302-c may enable and operate according to a truncated advertising mode based on the peripheral device 302-c currently operating with a quantity of connections satisfying a threshold quantity of connections for the peripheral device 302-c.

[0071] For example, the peripheral device 302-c may perform advertising and the central device 304-c may trigger a connection to the advertiser. The peripheral device 302-c may transmit an ADV_IND packet 310-b to advertise that the peripheral device 302-c supports peripheral LE connections. The central device 304-c may receive the ADV_IND packet 310-b, determine the existence of a relatively nearby Bluetooth device advertising LE peripheral connections, and may determine to connect to the peripheral device 302-c. The central device 304-c may transmit an AUX_CONNECT_REQ packet 316 to the peripheral device 302-c indicating the BD ADDR of the central device 304-c and one or more connection parameters for the requested connection. The central device 304-c may monitor for an

AUX CONNECT RESP packet 318 in response to the AUX CONNECT REQ packet 316. However, based on operating in the truncated advertising mode, the peripheral device 302-c may refrain from transmitting the AUX_CONNECT_RESP packet 318. If the central device 304-c fails to receive the AUX_CONNECT_RESP packet 318, the central device 304-c, the peripheral device 302-c, or both may back-off from the connection procedure (for example, randomly, pseudo-randomly, or after a threshold time). The central device 304-c and the peripheral device 302-c may determine that the connection failed to establish.

[0072] If the connection fails to establish, the central device 304-c may perform additional monitoring for advertising to discover and connect with another peripheral device (or with the peripheral device 302-c after the peripheral device 302-c disconnects at least one connection). The peripheral device 302-c may similarly perform further advertising. The peripheral device 302-c may additionally determine whether to disconnect a current connection to allow for connection with the central device 304-c based on the BD ADDR of the central device 304-c indicated by the AUX CONNECT REQ packet 316 [0073] Figure 4 shows an example process flow 400 that supports barge-in multipoint connections. The process flow 400 includes operations associated with a truncated page scan mode.

[0074] Figure 5 shows an example process flow 500 that supports barge-in multipoint connections. The process flow 500 includes operations associated with a truncated advertising mode. The process flow 500 includes options for using a CONNECT_IND or an AUX_CONNECT_REQ as a connection request packet for the advertising procedure.

[0075] Figure 6 shows an example process flow 600 that supports barge-in multipoint connections. The process flow 600 may include multiple wireless communication devices capable of Bluetooth operations, such as a first wireless communication device 602-a, a second wireless communication device 602 -b, a third wireless communication device 602-c, and a fourth wireless communication device 602-d. The first wireless communication device 602-a may operate as a peripheral device supporting multipoint connections with multiple central devices. For example, the second wireless communication device 602 -b, the third wireless communication device 602-c, and the fourth wireless communication device 602-d may be examples of central devices. In some examples, the process flow 600 may be implemented by aspects of the wireless communication network 100 as descnbed herein with reference to Figure 1. For example, the wireless communication devices may be examples of STAs 104, wireless communication devices, or peripheral and central devices as described herein with reference to Figures 1-3C. In the following description of the process flow 600, the operations between the devices may be performed in different orders or at different times. Some operations may be left out of the process flow 600, or other operations may be added. Although the wireless communication devices are show n performing the operations of the process flow' 600, some aspects of some operations may be performed by one or more other devices. For example, any wireless device (such as a STA 104 or an AP 102) may use the techniques described herein to support barge-in multipoint connections.

[0076] At 604, the first wireless communication device 602-a may establish multiple wireless communication links with multiple wireless communication devices. For example, the first wireless communication device 602-a may establish a first wireless communication link (for example, a first connection) with the second wireless communication device 602-b. The first wireless communication device 602-a may establish an additional wireless communication link (for example, an additional connection) with the fourth wireless communication device 602-d. The established wireless communication links may satisfy a threshold quantity of wireless communication links. For example, the first wireless communication device 602-a may support up to the threshold quantify of wireless communication links (for example, a maximum quantify of connections), and the first wireless communication device 602-a may be currently operating with a quantify of connections equal to the threshold quantify of wireless communication links. The multiple wireless communication links may include at least a first wireless communication link corresponding to an idle (for example, non-streaming) connection with a device (for example, the second wireless communication device 602-b).

[0077] At 606. the first wireless communication device 602-a may enable a truncated mode (for example, a truncated page scan mode or a truncated advertising mode) based on the quantify of the multiple wireless communication links satisfying the threshold quantify of wireless communication links for the first wireless communication device 602-a.

[0078] In some implementations, at 608, the first wireless communication device 602-a may perform a truncated page scan. For example, the first wireless communication device 602-a may be an example of a BR/EDR Bluetooth device. The first wireless communication device 602-a may enable the truncated page scan mode at 606 and may perform the truncated page scan at 608. Performing the truncated page scan may involve the first wireless communication device 602-a receiving, at 610 and from a third wireless communication device 602-c, an FHS packet including an indication of a BD ADDR corresponding to the third wireless communication device 602-c.

[0079] In some other implementations, at 612, the first wireless communication device 602-a may perform truncated advertising. For example, the first wireless communication device 602-a may be an example of an LE Bluetooth device. The first wireless communication device 602-a may enable the truncated advertising mode at 606 and may perform the truncated advertising at 612. Performing the truncated advertising may involve the first wireless communication device 602-a receiving, from a third wireless communication device 602-c, a connection request packet including an indication of a BD ADDR corresponding to the third wireless communication device 602-c. In some examples, the connection request packet may be an example of a CONNECT_IND packet. For example, at 614, the first wireless communication device 602-a may receive the CONNECT_IND packet indicating the BD_ADDR for the third wireless communication device 602-c. In some other examples, the connection request packet may be an example of an AUX_CONNECT_REQ packet. For example, at 616, the first wireless communication device 602-a may receive the AUX CONNECT REQ packet indicating the BD ADDR for the third wireless communication device 602-c.

[0080] The first wireless communication device 602-a may refrain from completing the discovery' and connection procedure with the third wireless communication device 602-c. Instead, the first wireless communication device 602-a may determine whether to establish a connection with the third wireless communication device 602-c. In some examples, the first wireless communication device 602-a may determine that a PDL stored at the first wireless communication device 602-a includes the BD_ADDR corresponding to the third wireless communication device 602-c and may determine to establish the connection with the third wireless communication device 602-c based on the PDL including the BD ADDR.

[0081] If the first wireless communication device 602-a determines to establish a connection w ith the third wireless communication device 602-c, the first w ireless communication device 602-a may first disconnect at least one current w ireless communication link (for example, to avoid exceeding or otherwise violating the threshold quantity of w ireless communication links). At 618, the first wireless communication device 602-a may disconnect the first wireless communication link corresponding to the idle connection (for example, the link with the second w ireless communication device 602 -b) based on the BD ADDR and the quantity of the multiple w ireless communication links satisfying the threshold quantity of w ireless communication links for the first wireless communication device 602-a. At 620, the first w ireless communication device 602-a may disable the truncated mode (for example, the truncated page scan mode or the truncated advertising mode) based on disconnecting the first wireless communication link. [0082] In some implementations, at 622, the first wireless communication device 602-a may perform a normal page scanning process based on disabling the truncated page scan mode. In some other implementations, at 624, the first wireless communication device 602-a may perform a normal advertising process based on disabling the truncated advertising mode. The third wireless communication device 602-c may discover and connect to the first wireless communication device 602-a based on the normal page scanning process or the normal advertising process. For example, at 626, the first wireless communication device 602-a may establish a second wireless communication link with the third wireless communication device 602-c based on disconnecting the first wireless communication link.

In some implementations, one or more processors of the processing system include or implement one or more of the modems. The processing system may further include or be coupled with multiple radios (collectively “the radio”), multiple RF chains or multiple transceivers, each of which may in turn be coupled with one or more of multiple antennas. In some implementations, one or more processors of the processing system include or implement one or more of the radios, RF chains or transceivers.

In some examples, the wireless communication device 700 further includes a user interface (UI) (such as a touchscreen or keypad) and a display, which may be integrated with the UI to form a touchscreen display that is coupled with the processing system. In some examples, the wireless communication device 700 may further include one or more sensors such as, for example, one or more inertial sensors, accelerometers, temperature sensors, pressure sensors, or altitude sensors, that are coupled with the processing system.
