Field of the Disclosure

[0003] The following relates to wireless communications, and more particularly, to techniques for connecting user equipment (UE) to multiple base stations through a wireless repeater. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and so on. These systems may be capable of supporting communication with multiple users by sharing available system resources, such as time, frequency, and power. Examples of such multi-access systems include fourth generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems may employ various techniques, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multi-access communication system may include several base stations or network access nodes, each of which simultaneously supports communication of multiple communication devices, which may also be referred to as UEs.

[0005] Some wireless communication systems may support the use of wireless repeaters. For example, a wireless repeater may be located between a UE and a base station and may relay and extend the communication between the base station and the UE. In some cases, the wireless repeater may be close to multiple base stations. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for connecting user equipment (UE) to multiple base stations via a wireless repeater. The described techniques provide for transmitting control information from multiple base stations to the wireless repeater so that the wireless repeater can communicate with the UEs associated with each base station. As an example, the wireless repeater can be in communication with two or more base stations that are connected to respective sets of UEs. In some cases, the wireless repeater can identify a first base station among the two or more base stations as the primary base station, and the wireless repeater can monitor control information from the primary base station. The primary base station can transmit control information to the wireless repeater, where the control information can include control information (e.g., beam information, communication direction, etc.) from a second base station that can be used by the wireless repeater to communicate with one or more UEs connected to the second base station. Here, the primary base station can receive an indication of the control information from the second base station (e.g., via a backhaul link), and the primary base station can transmit the control information to the wireless repeater on behalf of the second base station. As a result, the repeater can receive control information from the first base station, the second base station, or both by monitoring transmissions from the primary base station.

[0007] Additionally or alternatively, the wireless repeater can use a configuration for monitoring control information from the two or more base stations. For example, the wireless repeater can be configured with a mode for monitoring control signaling from a first base station and a second base station. The mode can include periodic time intervals during which the wireless repeater monitors control information from the respective base stations (e.g., a first time interval for control signaling from the first base station and a second time interval for control signaling from the second base station). In this way, the wireless repeater can monitor control information from multiple base stations, and the wireless repeater can communicate with the UEs connected to each base station based on the control information received during these time intervals.

[0055] In a wireless communication system, a base station may communicate with a user equipment (UE) over a wireless link. For example, the base station and the UE may operate in a millimeter wave (mmW) frequency range (e.g., 28 gigahertz (GHz), 40 GHz, 60 GHz, etc.). Wireless communication at these frequencies may be associated with increased signal attenuation (e.g., path loss), which may be affected by various factors such as temperature, air pressure, diffraction, being blocked by physical objects, etc. As a result, signal processing techniques such as beamforming may be used to coherently combine energy and overcome path loss at these frequencies. However, transmission of a signal (such as a beamformed signal) between the base station and the UE may be impossible or may be interfered with due to physical obstacles or radio frequency (RF) interferers. In these cases, a relay device (e.g., a wireless repeater, an mmW repeater, etc.) may be used to extend, repeat, and / or relay transmissions from the base station to the UE (and vice versa), thereby enabling efficient communication in the presence of RF interferers.

[0056] In some examples, the wireless repeater may be controlled by a base station, which indicates to the repeater how to communicate with one or more UEs and the base station. The base station may provide control signaling that indicates, for example, a certain beam (e.g., a directional beam or a symbol period associated with a beam) that the repeater may use to communicate with the base station and the UEs, a communication direction for transmission (e.g., uplink, downlink), or other types of information.

[0057] In some systems, a wireless repeater may be close to multiple base stations, with each base station connected to a corresponding set including one or more UEs. In such a scenario, each UE may communicate with a base station via the repeater. For example, a first UE may be connected to a first base station, and the transmission between the first UE and the first base station may be conveyed via the wireless repeater. Similarly, a second UE may communicate with a second base station in the same manner. However, communicating control information associated with the functionality of the repeater may introduce complexity to the system. For example, the repeater may not be able to receive control information from different base stations (e.g., in different directions) simultaneously due to the directionality of the beams used for transmitting and receiving control signaling. Similarly, the repeater may not be able to prioritize the communications of different devices without coordination and control information from these base stations. Thus, providing control information to a repeater in communication with multiple devices may be complex.

[0058] The techniques described for transmitting control signaling from multiple base stations to a wireless repeater can enable efficient control of the repeater to communicate with UEs connected to different base stations. For example, two or more base stations may coordinate control signaling for the wireless repeater, where one base station may act as a master base station that conveys control information to the repeater on behalf of these two base stations. More specifically, a first base station (e.g., the master base station) may receive information for controlling the wireless repeater from a second base station, and the first base station may signal the repeater with this information associated with the second base station. Here, these base stations may coordinate and configure control information on the backhaul link. Additionally, the repeater may identify the first base station as the master base station, and the repeater may monitor control information from the master base station. Thus, the wireless repeater can avoid monitoring control information from base stations not identified as the master base station, thereby limiting the operations performed by the wireless repeater to receive control information from different base stations (e.g., forming receive beams in multiple different directions and at different times).

[0059] In another example, each base station may transmit control information to the repeater individually, where the configured and coordinated transmission times may be used by these base stations to transmit control information according to a control signaling pattern. In such a scenario, the repeater may be configured with time intervals (e.g., periodic time intervals) that direct the repeater to receive control signaling from each base station during the corresponding time intervals, where the signaling may be differentiated for each base station based on an identifier. In one example, the time periods for receiving control signaling may be time-division multiplexed, where a first base station may transmit control information during a first time period and a second base station may transmit control information during a different second time period, and so on. As a result, the wireless repeater may be controlled by multiple different base stations to ensure communication between each base station and its corresponding UE. Additionally, the control command pattern may enable the wireless repeater to efficiently form receive beams in the corresponding directions for each time period (and each base station).

[0060] Aspects of the present disclosure are initially described in the context of a wireless communication system. Further examples are then described with reference to a process flow that illustrates the efficient conveyance of control information from multiple base stations to a wireless repeater. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flowcharts related to techniques for connecting a UE to multiple base stations via a wireless repeater.

[0061] Figure 1 An example of a wireless communication system 100 that supports techniques for connecting a wireless repeater to multiple base stations in accordance with various aspects of the present disclosure is illustrated. The wireless communication system 100 may include base stations 105, UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some scenarios, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0062] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be different forms of devices or devices with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110, and the UEs 115 and the base stations 105 may establish communication links 125 over the coverage area 110. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 support signal communication according to one or more radio access technologies.

[0063] Each UE 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UE 115 may be different forms of devices or devices with different capabilities. In Figure 1 some example UEs 115 are illustrated. The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as Figure 1 shown.

[0064] Each base station 105 may communicate with the core network 130 or with each other or both. For example, the base station 105 may interface with the core network 130 via a backhaul link 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both directly and indirectly, on the backhaul link 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul link 120 may be or include one or more wireless links. In some examples, the base station 105 may communicate wirelessly with one or more wireless repeaters 150 (e.g., relay devices, repeaters, or other similar terms), and the one or more wireless repeaters 150 may support retransmission, amplification, frequency conversion, etc. of signaling to one or more other devices, such as UEs 115. Similarly, the wireless repeater 150 may be used to retransmit signaling from the UE 115 to the base station 105.

[0065] One or more of the base stations 105 described herein may include or may be referred to by those of ordinary skill in the art as base transceiver stations, radio base stations, access points, radio transceivers, B nodes, evolved B nodes (eNBs), next-generation B nodes, or gigabit B nodes (any of which may be referred to as gNBs), home B nodes, home evolved B nodes, or other suitable terms.

[0066] The UE 115 may include or may be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where "device" may also be referred to as a unit, station, terminal, or client, etc. The UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, meters, etc.

[0067] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc., as Figure 1 shown.

[0068] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 over one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion (e.g., bandwidth part (BWP)) of a radio frequency spectrum band that operates according to the physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communicating with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0069] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling for coordinating the operation of other carriers. A carrier may be associated with a frequency channel (e.g., evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be positioned according to a channel raster for discovery by the UE 115. A carrier may operate in a stand-alone mode in which initial acquisition and connection may be performed by the UE 115 via the carrier, or a carrier may operate in a non-stand-alone mode in which the connection is anchored using a different carrier (e.g., different carriers of the same or different radio access technologies).

[0070] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink communication and uplink communication (e.g., in TDD mode).

[0071] A carrier may be associated with a certain bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of several predetermined bandwidths of the carrier of a radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., the base station 105, the UE 115, or both) may have a hardware configuration that supports communication on the carrier bandwidth, or may be configurable to support communication on one of the carrier bandwidths in a carrier bandwidth set. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0072] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include one symbol period (e.g., the duration of one modulated symbol) and one subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate of the UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can further increase the data rate or data integrity of communication with the UE 115.

[0073] One or more parameter sets may be supported for the carrier, where the parameter set may include subcarrier spacing (Δf) and cyclic prefix. The carrier may be divided into BWPs with the same or different parameter sets. In some examples, the UE 115 may be configured with multiple BWPs. In some cases, a single BWP for the carrier is active at a given time, and the communication for the UE 115 may be restricted to the active BWP.

[0074] The time intervals of the base station 105 or the UE 115 may be expressed as multiples of a basic time unit, which may refer to a sampling period T s = 1 / (Δf max ·N f ) seconds, where Δf max may represent the maximum supported subcarrier spacing, and N fmay represent the maximum supported discrete Fourier transform (DFT) size. A time interval of communication resources may be organized according to radio frames each having a specific duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0075] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some cases, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a plurality of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a plurality of symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-slots each containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0076] A subframe, time slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some cases, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0077] Physical channels can be multiplexed on a carrier according to various techniques. The physical control channel and the physical data channel can be multiplexed on a downlink carrier using, for example, time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for the physical control channel can be defined by the number of symbol periods and can extend across the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) can be configured for UE 115. For example, UE 115 can monitor or search for a control region for control information according to one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the encoded information for a control information format with a given payload size. The search space set can include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set configured to send control information to a specific UE 115.

[0078] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or various combinations thereof). The term "cell" can refer to a logical communication entity for communicating with a base station 105 (e.g., on a carrier) and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or others) for distinguishing adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion of the geographic coverage area 110 (e.g., a sector) on which the logical communication entity operates. The scope of such cells can vary from a smaller area (e.g., a structure, a subset of a structure) to a larger area depending on various factors (such as the capabilities of the base station 105). For example, a cell can be or include a building, a subset of a building, an external space between or overlapping with the geographic coverage area 110, and so on.

[0079] Macro cells cover a relatively large geographical area (e.g., with a radius of several kilometers) and may allow unconstrained access for UEs 115 having a service subscription with the network provider that supports the macro cell. Small cells may be associated with lower power base stations 105 (compared to macro cells), and small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as the macro cell. Small cells may provide unconstrained access to UEs 115 having a service subscription with the network provider, or may provide constrained access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office, etc.). Base station 105 may support one or more cells and may also support communication on one or more cells using one or more component carriers.

[0080] In some examples, a carrier may support multiple cells and may be configured with different cells according to different protocol types that may provide access for different types of devices (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB), or others).

[0081] In some examples, base station 105 may be mobile and thus provide communication coverage for a mobile geographical coverage area 110. In some examples, different geographical coverage areas 110 associated with different technologies may overlap, and different geographical coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographical coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network where different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographical coverage areas 110.

[0082] Wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, base stations 105 may have different frame timings, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operation.

[0083] A wireless device attempting to access a wireless network (such as UE 115, wireless repeater 150, or similar wireless devices) can perform an initial cell search by detecting the primary synchronization signal (PSS) from the base station 105. The PSS can achieve synchronization of slot timing and can indicate a physical layer identity value. The wireless device can then receive the secondary synchronization signal (SSS). The SSS can achieve radio frame synchronization and can provide a cell identity value, which can be combined with the physical layer identity value to identify the cell. The SSS can also achieve detection of the duplex mode and the cyclic prefix length. In some cases, the base station 105 can use multiple beams to transmit synchronization signals (e.g., PSS, SSS, etc.) in a beam sweeping manner through the cell coverage area. In some cases, the PSS, SSS, or broadcast information (e.g., physical broadcast channel (PBCH)) can be transmitted within different synchronization signal blocks (SSBs) on corresponding directional beams, and one or more SSBs can be included in a synchronization signal burst.

[0084] Some UEs 115 (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices integrated with sensors or meters to measure or capture information and relay such information to a central server or application, which utilizes the information or presents the information to a person interacting with the application. Some UEs 115 can be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wilderness survival monitoring, weather and geographical event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging. In some cases, the wireless repeater 150 can be an MTC or IoT device that is controlled by the base station 105 or UE 115 via a low-band or NB-IoT connection and relays the received signals based on the control information provided by the low-band or NB-IoT connection without demodulating or decoding such signals.

[0085] Some UEs 115 may be configured to operate in power-saving operation modes, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for the UE 115 include entering a power-saving deep sleep mode when not participating in active communication, or operating on a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of the carrier, or outside the carrier.

[0086] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. The UE 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication or group communication and may be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0087] In some cases, the UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or may not be able to receive transmissions from the base station 105 for other reasons. In some cases, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system where each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between the UEs 115 without involving the base station 105.

[0088] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some cases, vehicles in a V2X system can communicate with roadside infrastructure (such as roadside units), or with the network, or with both, using vehicle-to-network (V2N) communication via one or more network nodes (e.g., base station 105).

[0089] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and the EPC or 5GC can include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)), and at least one user plane entity that routes or interconnects packets to an external network (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions, such as the mobility, authentication, and bearer management of a UE 115 served by a base station 105 associated with the core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can be connected to a network operator IP service 155. The operator IP service 155 can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0090] Some network devices (such as base station 105) can include subcomponents, such as an access network entity 140, which can be an example of an access node controller (ANC). Each access network entity 140 can communicate with each UE 115 through several other access network transmission entities 145, which can be referred to as radio heads, intelligent radio heads, or transmit / receive points (TRPs). Each access network transmission entity 145 can include one or more antenna panels. In some examples, the various functions of each access network entity 140 or base station 105 can be distributed across various network devices (e.g., radio heads and ANCs) or combined into a single network device (e.g., base station 105).

[0091] The wireless communication system 100 may operate using one or more frequency bands, for example, in the range from 300 megahertz (MHz) to 300 gigahertz (GHz). The range from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) band or the decimeter band because the wavelengths are in the range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can sufficiently penetrate various structures for macro cells to provide service to UEs 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions can be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers).

[0092] The wireless communication system 100 may also operate in the super-high frequency (SHF) band in the range from 3 GHz to 30 GHz (also referred to as the centimeter band) or in the extremely high frequency (EHF) band in the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be smaller and more closely spaced than UHF antennas. In some cases, this may facilitate the use of antenna arrays within the devices. However, the propagation of EHF transmissions may experience even greater atmospheric attenuation and shorter ranges than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency bands, and the use of frequency bands designated across these frequency bands may vary by country or regulatory body.

[0093] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency bands. For example, the wireless communication system 100 may employ licensed-assisted access (LAA), Long Term Evolution-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency band, devices such as the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some cases, operation in the unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with a component carrier operating in a licensed band. Operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, device-to-device (D2D) transmissions, etc.

[0094] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some cases, the antennas or antenna arrays associated with base station 105 may be located at different geographical locations. Base station 105 may have an antenna array that has several rows and columns of antenna ports for beamforming that base station 105 can use to support communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0095] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0096] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., base station 105 or UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via the antenna elements of an antenna array such that some signals propagating in some orientations relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals communicated via the antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each antenna element may be defined by a set of beamforming weights associated with an orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0097] Base station 105 or UE 115 may use beam sweeping techniques as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by base station 105 multiple times in different directions. For example, base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by the transmitting device (such as base station 105) or the receiving device (such as UE 115)) to identify the beam direction used by base station 105 for subsequent transmissions or receptions.

[0098] Some signals (such as data signals associated with a receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device (such as UE 115)). In some examples, the beam direction associated with a transmission in a single beam direction may be determined based on signals transmitted in different beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality to base station 105.

[0099] In some cases, transmissions performed by a device (e.g., by base station 105 or UE 115) may use multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate the combined beam for transmission (e.g., from base station 105 to UE 105). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals that may be precoded or unencoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 may provide feedback for beam selection, and the feedback may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., polyhedral type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying the beam direction used by UE 115 for subsequent transmissions or receptions) or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

[0100] A receiving device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, the receiving device may attempt multiple receive directions by: receiving via different antenna sub-arrays, processing received signals according to different antenna sub-arrays, receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receive configurations or receive directions. In some examples, the receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0101] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly for communication over logical channels. The media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection supporting a radio bearer for user plane data between the UE 115 and the base station 105 or the core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0102] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve the throughput of the MAC layer in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some cases, a device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a particular slot for data received in a previous symbol in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0103] Wireless communication system 100 may include one or more wireless repeaters 150 (e.g., wireless repeater 150). Wireless repeater 150 may include functionality for relaying, extending, or redirecting wireless signals transmitted within the wireless communication system. In some cases, wireless repeater 150 may be used in a line-of-sight (LOS) or non-line-of-sight (NLOS) scenario. In an LOS scenario, a directed (e.g., beamformed) transmission (such as an mmW transmission) may be limited by path loss through the air. In an NLOS scenario (such as in an urban area or indoors), an mmW transmission may be limited by signal blockage or physical objects that interfere with the signal. In either scenario, wireless repeater 150 may be used to receive a signal from base station 105 and transmit the signal to UE 115, or to receive a signal from UE 115 and transmit the signal to base station 105. Wireless repeater 150 may use beamforming, filtering, gain control, and phase correction techniques to improve signal quality and avoid RF interference to the transmitted signal. Wireless repeater 150 may apply a phase rotation adjustment to the signal to correct for phase rotation errors caused by the frequency transformation of wireless repeater 150.

[0104] The wireless communication system 100 may support the transmission of control information from multiple base stations 105 to the wireless repeater 150, which may enable the wireless repeater 150 to communicate with the UEs 115 associated with each base station 105. As an example, the wireless repeater 150 may be in communication with two or more base stations 105 that are connected to a corresponding set of UEs 115 (e.g., receiving SSBs from the two or more base stations 105). In some cases, the wireless repeater 150 may identify a first base station 105 among the two or more base stations 105 as the primary base station 105, and the wireless repeater 150 may monitor control information from the primary base station 105 (e.g., while suppressing the monitoring of transmissions and control signaling from other base stations 105). The primary base station 105 may transmit control information to the wireless repeater 150, where the control information may include control information from a second base station 105 (e.g., mmW beam information, communication direction (i.e., uplink or downlink) information, etc.), and the control information may be used by the wireless repeater 150 to communicate with one or more UEs 115 connected to the second base station 105. In some examples, the primary base station 105 may receive an indication of the control information from the second base station 105 via a backhaul link, and the primary base station 105 may transmit the control information to the wireless repeater 150 on behalf of the second base station 105 and based on the received indication. In such cases, the base stations 105 may communicate with each other efficiently to coordinate control signaling to the wireless repeater 150. As a result, the wireless repeater 150 may receive control information from the first base station 105, the second base station 105, or both by monitoring transmissions from the primary base station 105.

[0105] In other examples, the wireless repeater 150 may use a configuration for monitoring control information from each of the two or more base stations 105. For example, the wireless repeater 150 may be configured with a mode for monitoring control signaling from the first base station 105 and the second base station 105. The mode may include periodic time intervals during which the wireless repeater 150 monitors control information from the respective base stations 105 (e.g., a first time interval for control signaling from the first base station 105 and a second time interval for control signaling from the second base station 105). As a result, the wireless repeater 150 may monitor control information from multiple base stations 105 and may communicate with the UEs 115 connected to each base station 105 based on the control information received during these time intervals.

[0106] Figure 2An example of a wireless communication system 200 that supports techniques for connecting a UE to multiple base stations via a wireless repeater in accordance with various aspects of the present disclosure is described. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. As shown, the wireless communication system 200 includes base stations 205-a, 205-b, UEs 215-a, and 215-b, which may be examples of the corresponding devices described with reference to Figure 1 The wireless communication system 200 also includes a wireless repeater 250, which may be used to relay transmissions between other devices within the wireless communication system 200.

[0107] In the wireless communication system 200, the base station 205-a may be connected to the wireless repeater 250. For example, the base station 205-a may send a transmission (e.g., an SSB, data, control information) to the wireless repeater 250 via a directional beam over a communication link 220-a. In some examples, the SSB may be transmitted in a corresponding symbol period, and each symbol period and SSB may correspond to a different beam direction. The wireless repeater may also be connected to the base station 205-b, where the base station 205-b may send a transmission to the wireless repeater 250 over the communication link 220-b. In some examples, the base station 205-a may communicate with the base station 205-b via a backhaul link 225.

[0108] Each base station 205 may be connected to one or more UEs 215 via the wireless repeater 250. For example, the UE 215-a may be connected to the base station 205-a or the base station 205-b, where the connection to one or both of these base stations 205 may be provided via the wireless repeater 250. Similarly, the UE 215-a may be connected to the base station 205-a or the base station 205-b or both via the wireless repeater 250. Alternatively, a corresponding set of UEs 215 may be connected to different base stations 205 via the wireless repeater 250. As an example, the UE 215-a may be from a set of one or more UEs 215 that are connected to the base station 205-a, while the UE 215-b may be from a set of one or more UEs 215 that are connected to the base station 205-b via the wireless repeater 250. Additionally, the UE 215-b may not be connected to the base station 205-a (which may be based on mobility prediction or other factors). As an example, the UE 215-b may have an additional link to the base station 205-b and may not be able to connect to the base station 205-a.

[0109] The wireless repeater 250 can amplify and forward transmissions it receives in the wireless communication system 200 (e.g., from base station 205-a, base station 205-b, UE 215-a, or UE 215-b). For example, the wireless repeater 250 can forward transmissions from base station 205-a to one or more UEs 215 connected to base station 205-a via communication link 220 and communication link 230, or vice versa. As described herein, each communication link 220 and each communication link 230 can be an example of beamformed communication between the wireless repeater 250 and the base station 205 or between the wireless repeater 250 and the UE 215, respectively.

[0110] In some examples, base station 205-a or base station 205-b can control the wireless repeater 250 using control information transmitted via a control interface (e.g., an in-band or out-of-band control interface). Here, the in-band control interface can include control information signaled within a portion of a broadband (e.g., wide signal bandwidth) transmission, which can include a BWP of the broadband bandwidth. In some cases, the broadband bandwidth can be the same bandwidth as that used by the wireless repeater 250 to communicate with base station 205-a (e.g., for receiving an SSB). The out-of-band control interface can refer to control signaling transmitted in a bandwidth or RF band different from the bandwidth or RF band used for transmitting / receiving an SSB, where the control signaling can be sent to the wireless repeater 250 separately from other transmissions. In some cases, the control information can be transmitted via a physical downlink control channel (PDCCH).

[0111] The control information received by the wireless repeater 250 can be related to beam selection and also provide instructions for transmission in the uplink or downlink (e.g., with UE 215 or with base station 205). For example, the control information can include power control, timing control, power saving, or beam weights, and the control information can indicate whether the wireless repeater communicates in the uplink by forwarding transmissions from UE 215 to base station 205 or in the downlink by forwarding transmissions from base station 205 to UE 215. The wireless repeater 250 can accordingly use the control information received via the control interface to set the beam direction for communicating with base station 205 and one or more UEs 215 connected to that base station 205.

[0112] In some cases, the wireless repeater 250 may not be able to receive control information from multiple base stations 205 simultaneously. However, as described herein, techniques can be implemented to enable multiple base stations 205 to provide control information to the wireless repeater 250 to enable communication between UEs 215 and base stations 205 in the wireless communication system 200.

[0113] In a first example, the wireless repeater 250 may view the base station 205-a as the primary base station 205 and may monitor the control interface from the base station 205-a based on identifying the base station 205-a as the primary base station 205. Additionally, the wireless repeater 250 may not monitor the control information from other base stations 205 (e.g., base station 205-b). In such a case, the base station 205-a may assign the downlink and uplink communication directions or beams that enable the wireless repeater 250 to forward the communication between the UE 215-a or UE 215-b and the respective base station 205 to which each UE 215 is connected. In other words, the base station 205-a may provide control information to the wireless repeater 250 on behalf of one or more other base stations 205 (e.g., including the base station 205-b).

[0114] The base station 205-a may receive an indication of the control information to be signaled to the wireless repeater 250 from other base stations 205. For example, the base station 205-a and the base station 205-b may be coupled via the backhaul link 225 and may coordinate signaling the control information to the wireless repeater 250 over the backhaul link 225. This coordination may include the base station 205-b providing an indication of the control information and scheduling information for communicating with one or more UEs 215 via the wireless repeater 250. The base station 205-a may receive this indication, and the base station 205-b may transmit the control information to the wireless repeater 250 via the control interface. As a result, the control information transmitted from the base station 205-a to the wireless repeater 250 may include the control information associated with the base station 205-b. This control information may enable the base station 205-b to control the wireless repeater 250 such that the base station 205-b may communicate with one or more UEs 215 (e.g., via the wireless repeater 250). In some examples, the control information transmitted by the base station 205-a may also include the information used by the base station 205-a to communicate with one or more UEs 215.

[0115] In a second example, the wireless repeater 250 may monitor the control interface (e.g., in-band PDCCH) for control information transmitted from multiple base stations 205, including the base station 205-a and the base station 205-b. In such a case, the base station 205-a and the base station 205-b may each transmit control information to the wireless repeater 250 according to a control signaling pattern. The control signaling pattern may indicate the resources used by each base station 205 on which the control information may be transmitted to the wireless repeater 250.

[0116] The control information transmitted by each base station 205 can be sent within the same BWP of the control interface. Thus, the wireless repeater 250 can monitor the same BWP for control information transmitted by base stations 205-a and 205-b. In some examples, the identifiers (IDs) of base stations 205-a and 205-b (such as physical (PHY) layer IDs (e.g., radio network temporary identifiers (RNTIs))) can be different, where the ID can enable the wireless repeater 250 to distinguish between the control information transmitted by each base station 205. The control signaling mode can enable the wireless repeater 250 to identify when (and on which resources) to monitor the control information sent from different base stations 205.

[0117] In some examples, the control signaling mode can be configured to coordinate the signaling of the control information sent by each base station 205. As an example, the wireless repeater 250 can receive control information from base stations 205-a and 205-b in a TDM manner. For example, base station 205-a can transmit control information during a first time period (e.g., time slot, symbol period, etc.), and base station 205-b can transmit control information during a different second time period (e.g., another time slot, another symbol period, etc.). The TDM mode (e.g., the time period for control signaling) can be configured between base stations 205-a and 205-b (e.g., via the backhaul link 225 or via other signaling). In other cases, the control signaling mode can be predefined. In some examples, base stations 205-a and 105-b can have an aperiodic resource configuration during which the wireless repeater 250 can monitor the control information from base station 205. In such cases, the wireless repeater 250 can, for example, monitor the control information from base station 205-a during even time slots (e.g., according to the time slot index) and monitor the control information from base station 205-b during odd time slots. It should be noted that other resource configurations and modes for receiving control signaling not explicitly described herein are also possible.

[0118] Figure 3 An example of process flow 300 in a system supporting techniques for connecting a UE to multiple base stations via a wireless repeater in accordance with various aspects of the present disclosure is illustrated. In some examples, process flow 300 can implement aspects of wireless communication system 100 or wireless communication system 200. For example, process flow 300 can include base stations 305-a, 305-b, UE 315, and wireless repeater 350, which can be examples of the corresponding devices described with reference to Figure 1 and Figure 2 The following alternative examples can be implemented, where some processes are performed in a different order than described or not at all. In some implementations, the processes can include additional features not mentioned below, or further processes can be added.

[0119] At 320, the wireless repeater 350 may identify base stations 305-a and 305-b. For example, the wireless repeater 350 may receive SSBs from base stations 305-a and 305-b, or be in communication with base stations 305-a and 305-b. At 325, base station 305-a may optionally receive from base station 305-b an indication of control information for the wireless repeater 350 to communicate with UE 315 (or other UEs connected to base station 305-b). This indication of the control information may be received on the backhaul link between base stations 305-a and 305-b. The control information may include an indication of the directional beam for the wireless repeater 350 to communicate with UE 315 or other UEs, and may further indicate whether these communications are for uplink transmission or for downlink transmission.

[0120] In some examples, at 330, base station 305-a may optionally determine a control signaling mode based on identifying that base station 305-b is connected to UE 315 via the wireless repeater 350. In some examples, the control signaling mode may include different time periods in which base stations 305-b and 305-a may be used to convey control information to the wireless repeater 350.

[0121] Based on the control signaling mode determined at 330, both base stations 305-a and 305-b may convey control information to the wireless repeater 350. For example, at 340, base station 305-a may convey control information for the wireless repeater 350 to communicate with UE 315, where the control information may be conveyed according to the determined control signaling mode. Similarly, base station 305-a may convey control information to the wireless repeater 350 according to the control signaling mode, and this control information may be used to enable communication between base station 305-a and the UE.

[0122] Additionally or alternatively, at 340, base station 350-a may convey control information to the wireless repeater 350 (e.g., acting as the primary base station 305). In such cases, the wireless repeater 350 may accordingly monitor the control information from base station 305-a but not the control information from base station 305-b. The control information conveyed by base station 305-a at 340 and received by the wireless repeater 350 may include control information associated with base station 305-b, as indicated at 325.

[0123] At 345, control information received at the wireless repeater 350 may enable the base station 305-b to communicate with the UE 315 via the wireless repeater 350. In such a case, the wireless repeater 350 may receive control information from multiple base stations 305 - either via the primary base station 305 (e.g., base station 305-a) or via the control signaling mode used by base station 305-a and base station 305-b for transmitting control information - and the wireless repeater 350 may communicate with one or more UEs 315 connected to the respective base stations 305.

[0124] Figure 4 FIG. 400 is a block diagram showing an apparatus 405 that supports techniques for connecting a UE to multiple base stations via a wireless repeater, in accordance with various aspects of the present disclosure. The apparatus 405 may be an example of aspects of a wireless repeater (such as the wireless repeater 150 as Figure 1 shown herein). The apparatus 405 may include a receiver 410, a wireless repeater communication manager 415, and a transmitter 420. The apparatus 405 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0125] The receiver 410 may receive information, such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to techniques for connecting a UE to multiple base stations via a wireless repeater, etc.). The information may be passed to other components of the apparatus 405. The receiver 410 may be an example of aspects of the transceiver 720 described with reference to Figure 7 FIG. The receiver 410 may utilize a single antenna or an antenna array.

[0126] The wireless repeater communication manager 415 may: identify a first base station and a second base station; communicate with one or more UEs based on control information; and receive control information from the first base station for communicating with one or more UEs connected to the second base station via the wireless repeater. The wireless repeater communication manager 415 may also: identify a first base station and a second base station; receive first control information from the first base station for communicating with a first group of one or more UEs connected to the first base station via the wireless repeater; and receive second control information from the second base station for communicating with a second group of one or more UEs connected to the second base station via the wireless repeater, where the first control information and the second control information are received according to a control signaling mode. The wireless repeater communication manager 415 may be an example of aspects of the wireless repeater communication manager 710 described herein.

[0127] The wireless repeater communication manager 415 or its sub-components may be implemented in hardware, code executed by a processor (e.g., software or firmware), or any combination thereof. If implemented in code executed by a processor, the functionality of the wireless repeater communication manager 415 or its sub-components may be performed by a general-purpose processor, a DSP, an application specific integrated circuit (ASIC), an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described in this disclosure.

[0128] The wireless repeater communication manager 415 or its sub-components may be physically located in various positions (including being distributed) such that portions of the functionality are implemented by one or more physical components at different physical locations. In some examples, in accordance with various aspects of the present disclosure, the wireless repeater communication manager 415 or its sub-components may be separate and distinct components. In some examples, in accordance with various aspects of the present disclosure, the wireless repeater communication manager 415 or its sub-components may be combined with one or more other hardware components (including but not limited to input / output (I / O) components, transceivers, network servers, another computing device, one or more other components described in this disclosure, or any combination thereof).

[0129] Actions performed by the wireless repeater communication manager 415 as described herein may be implemented to achieve one or more potential advantages. For example, the wireless repeater communication manager 415 may efficiently receive control information from multiple base stations and may thus communicate with multiple UEs connected to each base station based on the received control information. This implementation may enable the wireless repeater to provide enhanced coverage to one or more UEs in a wireless system. In some instances, the wireless repeater communication manager 415 may receive control information from a master base station, where the control information includes instructions from multiple base stations for forwarding signaling to / from respective UEs. This implementation may advantageously reduce complexity at the wireless repeater by configuring beam patterns that enable the wireless repeater to efficiently detect signaling transmitted at the physical layer by a single base station and also to process control information from multiple base stations. Additionally or alternatively, the wireless repeater may be configured to detect signaling from different base stations (and in different directions) via coordinated and controlled beam patterns. By enabling the wireless repeater to use the described techniques to connect UEs to their respective base stations, the communication quality and reliability of each of the UEs communicating with different base stations via the wireless repeater may be increased.

[0130] The transmitter 420 may transmit signals generated by other components of the device 405. In some examples, the transmitter 420 may be co-located with the receiver 410 in a transceiver component. For example, the transmitter 420 may be as referred to Figure 7Examples of aspects of the transceiver 720 described. The transmitter 420 may utilize a single antenna or an antenna array.

[0131] Figure 5 FIG. 500 is a block diagram illustrating an apparatus 505 that supports techniques for connecting a UE to multiple base stations via a wireless repeater, in accordance with various aspects of the present disclosure. The apparatus 505 may be an example of aspects of the apparatus 405 or a wireless repeater as described herein. The apparatus 505 may include a receiver 510, a wireless repeater communication manager 515, and a transmitter 530. The apparatus 505 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0132] The receiver 510 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to techniques for connecting a UE to multiple base stations via a wireless repeater, etc.). The information may be passed to other components of the apparatus 505. The receiver 510 may be an example of aspects of the transceiver 720 described with reference to Figure 7 Examples of aspects of the transceiver 720 described. The receiver 510 may utilize a single antenna or an antenna array.

[0133] The wireless repeater communication manager 515 may be an example of aspects of the wireless repeater communication manager 415 as described herein. The wireless repeater communication manager 515 may include a link manager 520 and a wireless repeater control manager 525. The wireless repeater communication manager 515 may be an example of aspects of the wireless repeater communication manager 710 described herein.

[0134] The link manager 520 may identify a first base station and a second base station and communicate with one or more UEs based on the control information. The wireless repeater control manager 525 may receive control information from the first base station for communicating with one or more UEs connected to the second base station via the wireless repeater. The link manager 520 may identify the first base station and the second base station.

[0135] The wireless repeater control manager 525 may: receive first control information from the first base station for communicating with a first group of one or more UEs connected to the first base station via the wireless repeater; and receive second control information from the second base station for communicating with a second group of one or more UEs connected to the second base station via the wireless repeater, the first control information and the second control information being received according to a control signaling mode.

[0136] The transmitter 530 may transmit signals generated by other components of the apparatus 505. In some examples, the transmitter 530 may be co-located with the receiver 510 in a transceiver component. For example, the transmitter 530 may be described with reference toFigure 7 Examples of aspects of the transceiver 720 described. The transmitter 530 may utilize a single antenna or an antenna array.

[0137] Based on at least one beam pattern configured to connect a UE to one or more base stations via a wireless repeater, a processor of the wireless repeater (e.g., which controls the receiver 510, the transmitter 530, or the transceiver 720 as described with reference to Figure 7 can efficiently determine where and when control information from these base stations is expected. Additionally, the processor of the wireless repeater can configure the beam pattern for receiving instructions from one or more base stations accordingly and further enable the transmission of information on behalf of a corresponding set of UEs. The processor of the wireless repeater can activate one or more processing units to monitor signaling, configure beam patterns (e.g., for receiving beams, transmitting beams), identify control information within the received signaling, or similar mechanisms within the wireless repeater. Thus, when control signaling (e.g., control information within the PDCCH) from another wireless device is received at the wireless repeater, the processor can be ready to respond more efficiently by reducing the ramp-up of processing power.

[0138] Figure 6 FIG. 600 is a block diagram illustrating a wireless repeater communication manager 605 that supports techniques for connecting a UE to multiple base stations via a wireless repeater in accordance with various aspects of the present disclosure. The wireless repeater communication manager 605 may be an example of aspects of the wireless repeater communication manager 415, the wireless repeater communication manager 515, or the wireless repeater communication manager 710 described herein. The wireless repeater communication manager 605 may include a link manager 610, a wireless repeater control manager 615, a primary base station identifier 620, and a monitoring manager 625. Each of these components may communicate directly or indirectly with each other (e.g., via one or more buses).

[0139] The link manager 610 may identify a first base station and a second base station. In some examples, the link manager 610 may communicate with one or more UEs based on control information. In some examples, the link manager 610 may identify a first base station and a second base station. In some examples, the link manager 610 may receive a first set of synchronization signal blocks from the first base station and a second set of synchronization signal blocks from the second base station.

[0140] In some examples, the link manager 610 may identify a first base station based on a first set of synchronization signal blocks. In some examples, the link manager 610 may identify a second base station based on a second set of synchronization signal blocks. In some cases, the first base station is associated with a first identifier that is different from a second identifier associated with the second base station. In some cases, the first identifier includes a first radio network temporary identifier, and the second identifier includes a second radio network temporary identifier.

[0141] The wireless repeater control manager 615 may receive control information from the first base station for communicating with one or more UEs connected to the second base station via the wireless repeater. In some examples, the wireless repeater control manager 615 may receive first control information from the first base station for communicating with a first set of one or more UEs connected to the first base station via the wireless repeater. In some examples, the wireless repeater control manager 615 may receive second control information from the second base station for communicating with a second set of one or more UEs connected to the second base station via the wireless repeater, and the first control information and the second control information are received according to a control signaling mode.

[0142] In some examples, the wireless repeater control manager 615 may receive control information in a portion of the bandwidth used for receiving one or more synchronization signal blocks from the first base station. In some examples, the wireless repeater control manager 615 may receive control information in a first bandwidth that is different from a second bandwidth used for receiving one or more synchronization signal blocks from the first base station. In some examples, the first control information is received in a first portion of the bandwidth used for receiving one or more synchronization signal blocks from the first base station.

[0143] In some examples, receiving the second control information includes receiving the second control information in a second portion of the bandwidth used for receiving one or more synchronization signal blocks from the second base station. In some cases, the control information includes an indication of at least one directional beam, a transmission direction, or any combination thereof for communicating with one or more UEs. In some cases, the control information is received on a physical downlink control channel. In some cases, the first portion and the second portion include the same bandwidth portion.

[0144] The primary base station identifier 620 may determine that the first base station is the primary base station controlling the wireless repeater. The monitoring manager 625 may monitor control information from the first base station based on the determination, wherein the control information is received from the first base station based on the monitoring. In some examples, the monitoring manager 625 may suppress monitoring of other control information from the second base station based on the determination.

[0145] In some examples, the monitoring manager 625 may monitor a first time period for receiving first control information from a first base station and a second time period for receiving second control information from a second base station based on a control signaling mode, where the first control information and the second control information are received based on the monitoring. In some cases, the first time period and the second time period do not overlap.

[0146] Figure 7 FIG. shows a system 700 including a device 705 that supports techniques for connecting a UE to multiple base stations via a wireless repeater, in accordance with various aspects of the present disclosure. The device 705 may be an example of or include components of the device 405, the device 505, or a wireless repeater as described herein.

These components may be in electronic communication via one or more buses (e.g., bus 745).

[0147] The wireless repeater communication manager 710 may: identify a first base station and a second base station; communicate with one or more UEs based on control information; and receive control information from the first base station for communicating with one or more UEs connected to the second base station via the wireless repeater. The wireless repeater communication manager 710 may also: identify a first base station and a second base station; receive first control information from the first base station for communicating with a first group of one or more UEs connected to the first base station via the wireless repeater; and receive second control information from the second base station for communicating with a second group of one or more UEs connected to the second base station via the wireless repeater, where the first control information and the second control information are received according to a control signaling mode.

[0148] The I / O controller 715 may manage the input and output signals of the device 705. The I / O controller 715 may also manage peripheral devices not integrated into the device 705. In some cases, the I / O controller 715 may represent a physical connection or port to an external peripheral device. In some cases, the I / O controller 715 may utilize an operating system, such as or another known operating system. In other cases, the I / O controller 715 may represent or interact with a modem, a keyboard, a mouse, a touch screen, or similar device. In some cases, the I / O controller 715 may be implemented as part of a processor. In some cases, a user may interact with the device 705 via the I / O controller 715 or via hardware components controlled by the I / O controller 715.

[0149] The transceiver 720 can perform two-way communication via one or more antennas, wired or wireless links, as described herein. For example, the transceiver 720 can represent a wireless transceiver and can perform two-way communication with another wireless transceiver. The transceiver 720 can also include a modem to modulate packets and provide the modulated packets to the antenna for transmission, and to demodulate packets received from the antenna. In some cases, the wireless device can include a single antenna 725. However, in some cases, the device can have more than one antenna 725, which can be capable of concurrently transmitting or receiving multiple wireless transmissions.

[0150] The memory 730 can include random access memory (RAM) and read-only memory (ROM). The memory 730 can store computer-readable, computer-executable code 735 that includes instructions that, when executed, cause the processor to perform the various functions described herein. In some cases, the memory 730 can particularly contain a basic input / output system (BIOS), which can control basic hardware or software operations, such as interactions with peripheral components or devices.

[0151] The processor 740 can include intelligent hardware devices (e.g., general-purpose processors, digital signal processors (DSPs), CPUs, microcontrollers, ASICs, field programmable gate arrays (FPGAs), programmable logic devices, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some cases, the processor 740 can be configured to operate a memory array using a memory controller. In other cases, the memory controller can be integrated into the processor 740. The processor 740 can be configured to execute computer-readable instructions stored in a memory (e.g., memory 730) to cause the device 705 to perform various functions (e.g., functions or tasks supporting techniques for connecting a UE to multiple base stations via a wireless repeater).

[0152] The code 735 can include instructions for implementing aspects of the present disclosure, including instructions for supporting wireless communication. The code 735 can be stored in a non-transitory computer-readable medium, such as system memory or other types of memory. In some cases, the code 735 may not be directly executable by the processor 740, but can cause a computer (e.g., when compiled and executed) to perform the functions described herein.
