[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 882,959, filed on August 5, 2019, entitled “TECHNIQUES FOR IN-BAND REPEATER CONTROL,” and U.S. Non-Provisional Patent Application No. 16 / 947,472, filed on August 3, 2020, entitled “TECHNIQUES FOR IN-BAND REPEATER CONTROL,” which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communications and techniques for in-band repeater control. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include several base stations (BS) that may support communications for several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at municipal, national, regional, and even global levels. NR (also known as 5G) is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR aims to support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to better integrate with other open standards, as well as support beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, further improvements are needed in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

[0007] In some aspects, a wireless communication method includes receiving an indication of a repeater configuration of a repeater in a bandwidth part (BWP) of a control interface carrying the repeater; and communicating with at least one of a base station (BS) or a user equipment (UE) based at least in part on the repeater configuration.

[0008] In some aspects, a repeater for wireless communication includes a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors are configured to receive an indication of a repeater configuration of the repeater in a BWP carrying a control interface of the repeater; and communicate with at least one of a BS or a UE based at least in part on the repeater configuration.

[0009] In some aspects, a non-transitory computer-readable medium stores one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a relay, cause the one or more processors to receive an indication of a relay configuration of the relay in a BWP carrying a control interface of the relay; and communicate with at least one of a BS or a UE based at least in part on the relay configuration.

[0010] In some aspects, an apparatus for wireless communication includes means for receiving an indication of a relay configuration of the apparatus in a BWP carrying a control interface of the apparatus; and means for communicating with at least one of a BS or a UE based at least in part on the relay configuration.

[0011] Aspects generally include methods, apparatuses, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication devices, and processing systems as generally described herein with reference to and as illustrated in the drawings and description.

[0023] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms, and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0024] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0025] Figure 11 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0026] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0027] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks using any appropriate transmission network, etc.).

[0028] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay station 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0029] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0030] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. These BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0031] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle-mounted component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0032] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may, for example, provide connectivity to a network (e.g., a wide area network, such as the Internet or a cellular network) or to a network via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as user premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, etc.

[0033] Typically, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0034] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0035] In some aspects, the repeater 140 may receive a radio frequency (RF) analog signal (e.g., an analog millimeter wave signal) from the base station 110, may amplify the RF analog signal, and may send the amplified RF signal to one or more UEs 120 (e.g., shown as UE 120f). In some aspects, the repeater 140 may be an analog millimeter wave (mmW) repeater, sometimes also referred to as a layer 1 mmW repeater. Additionally or alternatively, the repeater 140 may be a wireless transmit receive point (TRP) acting as a distributed unit (e.g., of a 5G access node), which wirelessly communicates with the base station 110 acting as a central unit or access node controller (e.g., of a 5G access node). The repeater 140 may receive, amplify, and transmit RF analog signals without performing analog-to-digital conversion of the RF analog signal and / or without performing any digital signal processing on the RF analog signal. In this way, latency may be reduced and the cost of producing the repeater 140 may be reduced. Other details about the repeater 140 are provided elsewhere herein.

[0036] As mentioned above, Figure 1 This is provided as an example only. Other examples may differ from the combination of Figure 1 The content described.

[0037] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, where the UE may be Figure 1 Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0038] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the (multiple) MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from the modulators 232a to 232t may be transmitted to the UE 120, the relay 140, etc., respectively, via the T antennas 234a to 234t. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0039] At the UE 120, antennas 252a to 252r may receive downlink signals from base stations 110, repeaters 140, and / or other wireless communication devices, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0040] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110 and / or the relay 140. At the base station 110, uplink signals from the UE 120, the relay 140, and / or other wireless communication devices may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0041] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of may perform or direct e.g. Figure 7 10 and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120, the one or more instructions may perform or direct, for example, Figure 7 The operations of process 700 and / or other processes described herein. The scheduler 246 can schedule UEs to transmit data on the downlink and / or uplink.

[0042] In some aspects, UE 120 may include components for sending uplink communications to BS 110 via relay 140, components for receiving downlink communications from BS 110 via relay 140, etc. In some aspects, such modules may include components in conjunction with Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0043] In some aspects, base station 110 may include means for configuring one or more relay configurations of relay 140, means for sending an indication of the one or more relay configurations to relay 140 in a bandwidth part (BWP) of a control interface carrying relay 140, means for sending downlink communications to UE 120 via relay 140, means for receiving one or more uplink communications from UE 120 via relay 140, etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of the base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0044] As mentioned above, Figure 2 This is provided as an example only. Other examples may differ from the combination of Figure 2The content described.

[0045] Figure 3 is a diagram illustrating an example of a repeater 300 according to various aspects of the present disclosure. In some aspects, the repeater 300 may correspond to Figure 1 In some aspects, the repeater 300 can be a millimeter wave repeater that communicates via millimeter wave transmissions (eg, as opposed to sub-6 GHz transmissions).

[0046] like Figure 3 As shown, the repeater 300 may include one or more antenna arrays (or antennas, antenna panels, etc.) 310-1 to 310-N (N>1), a gain component 320, a controller 330, a communication component 340, and a multiplexer (MUX) 350a and / or a demultiplexer (DEMUX) 350b (collectively referred to as MUX / DEMUX 350).

[0047] The antenna array 310 may include multiple antenna elements that can be configured for beamforming. For example, the antenna array 310 may be referred to as a phased array because the phase values ​​and / or phase offsets of the antenna elements may be configured to form beams, wherein different phase values ​​and / or phase offsets are used for different beams (e.g., in different directions). In some aspects, the antenna array 310 may be a fixed receive (Rx) antenna array that can only receive communications without sending communications. In some aspects, the antenna array 310 may be a fixed transmit (Tx) antenna array that can only send communications without receiving communications. In some aspects, the antenna array 310 may be configured to act as an Rx antenna array or a Tx antenna array (e.g., via a Tx / Rx switch, MUX / DEMUX, etc.). The antenna array 310 may communicate using millimeter waves and / or other types of RF analog signals.

[0048] The gain component 320 includes one or more components that can amplify the input signal and output the amplified signal. For example, the gain component 320 may include a power amplifier, a variable gain component, etc. In some aspects, the gain component 320 may have a variable gain control. The gain component 320 may be connected to an Rx antenna array (e.g., a first antenna array 310-1) and a Tx antenna array (e.g., a second antenna array 310-2) so that the RF analog signal received via the Rx antenna array can be amplified by the gain component 320 and output to the Tx antenna array for transmission. In some aspects, the amplification level of the gain component 320 may be controlled by a controller 330.

[0049] The controller 330 includes one or more components capable of controlling one or more other components of the repeater 300. For example, the controller 330 may include a controller, a microcontroller, a processor, etc. In some aspects, the controller 330 may control the gain component 320 by controlling the level of amplification or gain applied to the input signal by the gain component 320. Additionally or alternatively, the controller 330 may control the antenna array 310 by controlling the beamforming configuration of the antenna array 310 (e.g., one or more phase values ​​of the antenna array 310, one or more phase offsets of the antenna array 310, one or more power parameters of the antenna array 310, one or more beamforming parameters of the antenna array 310, Tx beamforming configuration, Rx beamforming configuration, etc.), by controlling whether the antenna array 310 acts as an Rx antenna array or a Tx antenna array (e.g., by configuring the interaction and / or connection between the antenna array 310 and the MUX / DEMUX 350), etc. Additionally or alternatively, controller 330 may power on or off one or more components of relay 300 (eg, when BS 110 does not need to use the relay to serve UE 120). In some aspects, controller 330 may control the timing of one or more of the above configurations.

[0050] Additionally or alternatively, the controller 330 can control the position of a switch 380 included in the repeater 300 to cause an oscillator 360 included in the repeater 300 to be connected to one or more antennas 310 associated with transmitting RF analog signals (e.g., via another gain component 370 included in the repeater 300). In some aspects, the controller 330 can control the gain component 370 by controlling the level of amplification or gain applied by the gain component 370 to the signal provided by the oscillator 360.

[0051] The communication component 340 may include a component capable of wirelessly communicating with the BS 110 via a control interface. In some aspects, the communication component 340 may communicate with the BS 110 using one or more in-band radio frequencies (e.g., radio frequencies included within the operating frequency bandwidth of the antenna arrays 310-1 to 310-N). In this case, the BS 110 may configure a BWP (e.g., an in-band BWP) within the operating frequency bandwidth of the antenna arrays 310-1 to 310-N such that the BWP carries a control interface associated with the repeater 300. In some aspects, the antenna array 310 may be used to wirelessly forward (e.g., transmit and / or receive) RF analog signals between the repeater 300 and the BS 110, between the repeater 300 and one or more UEs 120, etc., and the communication component 340 may be used to transmit control information between the repeater 300 and the BS 110.

[0052] In some aspects, communication component 340 may include one or more components for digital signal processing (e.g., a digital signal processor, a baseband processor, a digital-to-analog converter (DAC), an analog-to-digital converter (ADC), etc.) In this manner, communication component 340 may demodulate, decode, and / or perform other types of processing on control information received from BS 110.

[0053] The MUX / DEMUX 350 may be used to multiplex and / or demultiplex communications received from and / or transmitted to the antenna array 310. For example, the MUX / DEMUX 350 may be used to switch the Rx antenna array to the Tx antenna array.

[0054] The oscillator 360 can be used to generate an RF analog signal for the repeater 300 to send via the antenna array 310. The gain component 370 includes one or more components that can amplify the input signal and output the amplified signal (e.g., the amplified RF analog signal). For example, the gain component 370 may include a power amplifier, a variable gain component, etc. In some aspects, the gain component 370 may have a variable gain control. The gain component 370 may be connected to the oscillator 360 and the Tx antenna array (e.g., the antenna array 310) so that the RF analog signal provided by the oscillator 360 can be amplified by the gain component 370 and output to the Tx antenna array for transmission. In some aspects, the amplification level of the gain component 370 can be controlled by the controller 330.

[0055] The switch 380 includes one or more components that enable the repeater 300 to operate to relay a signal received via an Rx antenna array (e.g., the antenna array 310) or to transmit an RF analog signal generated by the repeater 300 (e.g., an RF analog signal generated by the oscillator 360 and amplified by the gain component 370). In some aspects, the position of the switch 380 may be controlled by the controller 330.

[0056] In some aspects, one or more antenna arrays 310, gain components 320, controllers 330, communication components 340, MUX / DEMUX 350, oscillators 360, gain components 370, switches 380, etc. may perform one or more techniques associated with in-band configuration of a repeater, as described in greater detail elsewhere herein. For example, one or more components of repeater 300 may perform or direct, for example, Figure 7 Operations of process 700 and / or other processes as described herein.

[0057] In some aspects, the relay 300 may include means for receiving an indication of a relay configuration of the relay in a BWP carrying a control interface of the relay, means for communicating with at least one of a BS or a UE based at least in part on the relay configuration, etc. In some aspects, such means may include in conjunction with Figure 3 One or more components of repeater 300 are depicted, such as antenna array 310 , gain component 320 , controller 330 , communication component 340 , MUX / DEMUX 350 , oscillator 360 , gain component 370 , and / or switch 380 .

[0058] As mentioned above, Figure 3 This is provided as an example only. Other examples may differ from the combination of Figure 3 For example, the repeater 300 may include Figure 3 Additional components, fewer components, different components, or differently arranged components than those shown. Figure 3 Two or more of the components shown in may be implemented in a single component, or Figure 3 A single component shown in can be implemented as multiple components. Additionally or alternatively, one set of components (eg, one or more components) of repeater 300 can perform one or more functions described as being performed by another set of components of repeater 300.

[0059] Figure 4 is a diagram illustrating an example 400 of a wireless access network in accordance with various aspects of the present disclosure.

[0060] As shown by reference numeral 405, a traditional (e.g., 3G, 4G, LTE, etc.) wireless access network may include multiple BSs 410 (e.g., access nodes (ANs)), wherein each BS 410 communicates with a core network via a wired backhaul link 415 (e.g., a fiber optic connection). BS 410 may communicate with UE 420 via an access link 425, which may be a wireless link. In some aspects, Figure 4 The BS 410 shown may correspond to Figure 1 BS 110 is shown. Similarly, Figure 4 The UE 420 shown may correspond to Figure 1 UE 120 is shown.

[0061] As shown in the reference numeral 430, the wireless access network may include a wireless backhaul network, sometimes referred to as an integrated access and backhaul (IAB) network. In an IAB network, at least one BS is an anchor BS 435, which communicates with the core network via, for example, a wired backhaul link 440 connected by an optical fiber. The anchor BS 435 may also be referred to as an IAB donor (or IAB-donor). The IAB network may include one or more non-anchor BSs 445, sometimes referred to as relay BSs or IAB nodes (or IAB-nodes). The non-anchor BS 445 may communicate directly with the anchor BS 435 via one or more backhaul links 450 or communicate indirectly (e.g., via one or more other non-anchor BSs 445) with the anchor BS 435 to form a backhaul path to the core network for carrying backhaul traffic. The backhaul link 450 may be a wireless link. The anchor BS 435 and / or the non-anchor BS 445 may communicate with one or more UEs 455 via an access link 460, which may be a wireless link for carrying access traffic. Figure 4 The anchor BS 435 and / or non-anchor BS 445 shown may correspond to Figure 1 BS 110 is shown. Similarly, Figure 4 The UE 455 shown may correspond to Figure 1 UE 120 is shown.

[0062] As indicated by reference numeral 465, in some aspects, a wireless access network including an IAB network may utilize millimeter wave technology and / or directional communication (e.g., beamforming, precoding, etc.) for communication between BSs and / or UEs (e.g., between two BSs, between two UEs, and / or between a BS and a UE). For example, a wireless backhaul link 470 between BSs may use millimeter waves to carry information and / or may use beamforming, precoding, etc. to point to a target BS. Similarly, a wireless access link 475 between a UE and a BS may use millimeter waves and / or may point to a target wireless node (e.g., a UE and / or a BS). In this way, inter-link interference may be reduced.

[0063] In some aspects, the IAB network may support a multi-hop network and / or a multi-hop wireless backhaul. Additionally or alternatively, each node of the IAB network may use the same radio access technology (e.g., 5G / NR). Additionally or alternatively, the nodes of the IAB network may share resources for access links and backhaul links, such as time resources, frequency resources, space resources, etc. In addition, various architectures of IAB nodes and / or IAB donors may be supported. In some aspects, the IAB donor may include a central unit (CU) that configures an IAB node that accesses a core network via the IAB donor, and the IAB donor may include a distributed unit (DU) that schedules a child node of the IAB donor and communicates with the child node of the IAB donor. The IAB node may include a mobile terminal (MT), which is scheduled by the DU of the parent node and communicates with the DU of the parent node, and may include a DU that schedules and communicates with the child node of the IAB donor. The DU of the node may perform the functions described herein in conjunction with the BS 110 of the node, and the MT of the node may perform the functions described herein in conjunction with the UE 120 of the node.

[0064] In some aspects, the propagation distance in an IAB network or another type of wireless communication network can be improved by using a repeater 140. For example, the repeater 140 can forward signals between a UE and a BS, an IAB donor, or an IAB node. As another example, the repeater 140 can forward signals between IAB donors, between an IAB donor and an IAB node, and so on. In some aspects, a "backhaul link" can refer to a link between a BS and a repeater 140, and an "access link" can refer to a link between a repeater 140 and a UE.

[0065] As mentioned above, Figure 4 This is provided as an example only. Other examples may differ from the combination of Figure 4 The content described.

[0066] Figure 5A-Figure 5C is a diagram illustrating an example 500 of communications using a repeater in accordance with aspects of the present disclosure.

[0067] Because millimeter wave communications have a higher frequency and shorter wavelength than other types of radio waves used for communication (e.g., communications below 6 GHz), millimeter wave communications can have a shorter propagation distance and can be more easily blocked by obstacles than other types of radio waves. For example, wireless communications using radio waves below 6 GHz can penetrate the walls of a building or structure to provide coverage of an area on the side of the wall opposite to the BS 110 that communicates using radio waves below 6 GHz. However, millimeter waves may not be able to penetrate the same wall (e.g., depending on the thickness of the wall, the material that makes up the wall, etc.). Some techniques and devices described herein use a repeater 140 to increase the coverage area of ​​a BS 110 (e.g., a BS 110 that communicates using millimeter wave communications and / or other types of communications) to extend coverage to a UE 120, etc., in the absence of a line of sight to the BS 110 (e.g., due to an obstacle).

[0068] For example, Figure 5A As shown in the example of , the obstacle between the UE and the BS blocks the link between the BS and the UE or otherwise reduces the quality of the link between the BS and the UE. However, there are no obstacles or fewer obstacles between the relay and the UE, and as a result, the communication between the relay and the UE will have a higher quality than the communication directly between the BS and the UE.

[0069] like Figure 5A As further shown in , the repeater can perform directional communication by using beamforming to communicate with the BS via a first beam pair (e.g., a backhaul beam pair on a backhaul link) and communicate with the UE via a second beam pair (e.g., an access beam pair on an access link). A "beam pair" may refer to a transmit (Tx) beam used by a first device for transmission and a receive (Rx) beam used by a second device for receiving information sent by the first device via the Tx beam.

[0070] like Figure 5B As shown, the repeater can relay or forward downlink communications by sending an RF analog signal received from the BS via the Rx beam of the first beam pair to the UE using the Tx beam of the second beam pair. In some aspects, the combination of the Rx beam of the first beam pair and the Tx beam of the second beam pair can be referred to as a downlink path.

[0071] As used herein, relaying or forwarding a received RF analog signal may refer to sending the received RF analog signal (e.g., after amplifying the received RF analog signal) without decoding the received RF analog signal and / or without modifying the information carried in the received RF analog signal. Alternatively, relaying or forwarding a received RF analog signal may refer to sending the received RF analog signal after decoding the received signal and / or modifying the information carried in the received RF analog signal. In some aspects, a received RF analog signal may be relayed or forwarded using different time resources, different frequency resources, and / or different spatial resources (e.g., different beams) than the time resources, frequency resources, and / or spatial resources used to receive the RF analog signal to send the RF analog signal.

[0072] like Figure 5C As shown, the repeater can relay or forward uplink communication by sending the RF analog signal received from the UE via the Rx beam of the second beam pair to the BS using the Rx beam of the first beam pair. In some aspects, the combination of the Tx beam of the first beam pair and the Rx beam of the second beam pair can be referred to as an uplink path.

[0073] As mentioned above, providing Figure 5A-Figure 5C As an example. Other examples can be related to Figure 5A-Figure 5C Different than described.

[0074] As described above, a repeater (e.g., repeater 140, repeater 300, etc.) is capable of receiving and relaying or forwarding RF analog signals from a BS (e.g., BS 110) and a UE (e.g., UE 120). However, in order to reduce the cost and complexity of the repeater and / or to reduce the cost and complexity of deploying the repeater in a wireless network, the repeater may not be equipped and / or configured with hardware and / or software that would otherwise permit the repeater to track, monitor, and / or otherwise manage access links and corresponding beam pairs associated with the UE with which the repeater communicates. As a result, the repeater may generally be unable to determine which beams to use to communicate with the UE, may be unable to determine when the repeater is activated for forwarding communications between the BS and the UE, may be unable to determine when the repeater can operate in an idle mode or a low power mode (e.g., by powering off certain components and / or interfaces of the repeater), etc. This may result in reduced operating efficiency of the repeater. For example, the relay may consume processing, memory, and / or power resources when the relay should be in an idle mode or a low power mode, the relay may operate using a suboptimal beam to communicate with a BS and / or UE, etc.

[0075] Some aspects described herein provide techniques and devices associated with in-band repeater control. In some aspects, based at least in part on the fact that a repeater (e.g., repeater 140, repeater 300, etc.) can communicate with a BS and / or UE by relaying or forwarding RF analog signals between the BS and the UE, the BS can configure the repeater configuration. The BS can send an indication of the repeater configuration to the repeater via in-band control signaling. For example, the BS can send an indication of the repeater configuration on a control interface associated with the repeater, and the control interface can be carried in a BWP included in the operating frequency bandwidth of the repeater.

[0076] The BWP includes a set of continuous physical resource blocks of an operating frequency bandwidth, which is active and used by the repeater to forward communications between other wireless communication devices (e.g., UE, BS, etc.). The control interface can be a communication interface between the UE and the BS, which is configured to carry control signaling and / or control communications between the UE and the BS. The control interface is included in at least a portion of the set of continuous physical resource blocks of the BWP. Therefore, the indication of the repeater configuration is an in-band repeater configuration, wherein the indication of the repeater configuration is sent within the BWP (e.g., within the control interface). In this way, the indication of the repeater configuration can be sent to the repeater without the repeater being activated and using additional frequency resources outside the BWP, which reduces the memory resources, processing resource consumption, power consumption, and / or radio resource consumption of the repeater.

[0077] In addition, sending the repeater configuration to the repeater over the control interface in the BWP enables the BS to configure the repeater for efficient operation while allowing less complex repeaters to be deployed in the wireless network. For example, the BS can use the repeater configuration to indicate to the repeater one or more durations during which the repeater can communicate with the BS and / or UE, can indicate whether the repeater is operating in an idle mode or a low power mode (e.g., by powering on or off specific components of the repeater), can indicate whether the repeater is to activate an uplink path and / or a downlink path between the BS and the UE, can indicate one or more beamforming parameters, and / or other parameters. In this way, the repeater is enabled to receive in-band communications from the BS and is enabled to operate according to the parameters optimally selected for the repeater in the repeater configuration.

[0078] Figure 6A-6E is a diagram illustrating an example 600 of in-band repeater control according to various aspects of the present disclosure. Figure 6A-6EAs shown in , example 600 may include communications between a BS (e.g., BS 110), a UE (e.g., UE 120), and a relay (e.g., relay 140, relay 300, etc.). In some aspects, the BS, UE, and relay may be included in a wireless network (e.g., wireless network 100). In some aspects, the BS and / or UE may use the above combination Figure 2 Describes one or more components to perform the combined Figure 6A-6E In some aspects, the repeater may use the above combined Figure 3 Describes one or more components to perform the combined Figure 6A-6E One or more techniques described.

[0079] like Fig. 6A As shown in FIG. 1 and by reference numeral 602, to configure a repeater for communication with a BS and / or a UE, the BS may generate one or more repeater configurations and may send indications of the one or more repeater configurations to the repeater. In some aspects, the BS may send the indication of the repeater configuration via a control interface associated with the repeater and the repeater may receive the indication of the repeater configuration via a control interface associated with the repeater. In addition, the BS may send the indication of the repeater configuration in an in-band BWP carrying the control interface. In other words, the BWP may be included within the operating frequency bandwidth of the repeater (e.g., the frequency bandwidth used by the repeater to relay or forward RF analog signals between the BS and the UE).

[0080] The BWP includes a set of continuous physical resource blocks of an operating frequency bandwidth, which is active and used by the repeater to forward communications between other wireless communication devices (e.g., UE, BS, etc.). The control interface can be a communication interface between the UE and the BS, which is configured to carry control signaling and / or control communications between the UE and the BS. The control interface is included in at least a portion of the set of continuous physical resource blocks of the BWP. Therefore, the indication of the repeater configuration is an in-band repeater configuration, wherein the indication of the repeater configuration is sent within the BWP (e.g., within the control interface). In this way, the indication of the repeater configuration can be sent to the repeater without activating and using additional frequency resources outside the BWP.

[0081] In some aspects, a BS may direct the indication of one or more relay configurations to a relay (e.g., as opposed to communications directed to a UE) by sending an indication of the one or more relay configurations to the relay based at least in part on an identifier associated with the relay. For example, the BS may scramble a signaling communication carrying the indication of the one or more relay configurations based at least in part on a radio network temporary identifier (RNTI) associated with the relay, where the RNTI may be different from an RNTI or another identifier associated with the UE. In this case, the relay may receive the indication of the one or more relay configurations in the signaling communication and may descramble the signaling communication based at least in part on the RNTI associated with the relay.

[0082] In some aspects, the BS may specify (e.g., in a signaling communication identifying one or more relay configurations, in another signaling communication, etc.) that the relay is to provide an acknowledgment (ACK) or negative acknowledgment (NACK) feedback for a signaling communication identifying one or more relay configurations. For example, the BS may specify that the relay provides an ACK or a NACK. In this case, if the relay successfully receives and decodes the signaling communication, the relay may send an ACK to the BS, and if the relay cannot decode the signaling communication, the relay may send a NACK. As another example, the BS may specify that the relay will provide only ACK feedback. In this case, if the relay successfully receives and decodes the signaling communication, the relay may send an ACK to the BS, and if the relay cannot decode the signaling communication, no feedback is provided to the BS. As another example, the BS may specify that the relay will provide only NACK feedback. In this case, if the relay cannot decode the signaling communication, the relay may send a NACK to the BS, and if the relay successfully receives and decodes the signaling communication, no feedback is provided to the BS.

[0083] In some aspects, the BS may configure the repeater configuration to identify one or more durations during which the repeater can communicate with the BS and / or UE based at least in part on one or more configuration parameters identified in the repeater configuration. In some aspects, the BS may configure multiple candidate repeater configurations. Each candidate repeater configuration may include a combination of a duration and a configuration parameter. In this case, each candidate configuration may be a row or column indexed in a table, an electronic database, an electronic file, a specification, and / or another data structure. This allows the BS to send a signaling communication to the repeater that indexes into multiple candidate repeater configurations to identify the repeater configuration (e.g., by identifying a row index or column index associated with the repeater configuration).

[0084] The duration may include one or more symbols, one or more time slots, one or more subframes, one or more radio frames, and / or other time domain units. In some aspects, in a repeater configuration, the duration may be indicated by an explicit indication of a start time of the duration and / or an end time of the duration (e.g., by a symbol number, a time slot number, a frame number, etc.). In some aspects, in a repeater configuration, the duration may be indicated by a start time and a timing offset relative to the start time (e.g., the number of symbols, time slots, and / or other time domain units relative to the start time), and the timing offset may implicitly indicate an end time.

[0085] In some aspects, the start time of the duration may be explicitly indicated in the repeater configuration. For example, the repeater configuration may specify a symbol number, a time slot number, a frame number, and / or a similar number at which the duration will begin. In some aspects, the start time of the duration may be implicitly indicated in the repeater configuration. For example, the repeater configuration may specify a timing offset (e.g., the number of symbols, time slots, and / or other time domain units) relative to the time at which a signaling communication identifying the repeater configuration is sent by the BS or received by the repeater. In this case, the timing offset (and thus the start time) may be based at least in part on the capabilities associated with the repeater. For example, the repeater may send an indication of a capability parameter associated with the repeater's ability to receive and process the repeater configuration to the BS. In this way, when configuring a duration for a repeater for a repeater, the BS may take into account the hardware and / or software capabilities of the repeater.

[0086] In some aspects, the configuration parameters included in the repeater configuration may include various operating mode parameters, communication path parameters, beamforming parameters, measurement parameters, reference signal parameters, and / or other types of configuration parameters. In some aspects, the repeater configuration may include one or more of the configuration parameters described herein and / or other configuration parameters.

[0087] In some aspects, the repeater configuration may indicate that the repeater will be powered on (e.g., the repeater will power on one or more components of the repeater, such as one or more antenna arrays 310, gain components 320, controller 330, communication components 340, MUX / DEMUX 350, oscillator 360, gain components 370, switch 380, etc.) and will operate in an active mode for a duration indicated in the repeater configuration. In some aspects, the repeater configuration may indicate that the repeater will power off one or more components of the repeater (e.g., one or more antenna arrays 310, gain components 320, controller 330, communication components 340, MUX / DEMUX 350, oscillator 360, gain components 370, switch 380, etc.) such that the repeater operates in an idle, deactivated, or low power mode for a duration indicated in the repeater configuration.

[0088] In some aspects, the repeater configuration may indicate that the repeater is to activate an uplink path between the BS and the UE during a duration indicated in the repeater configuration and / or is to activate a downlink path between the BS and the UE during the duration. In this case, the repeater may activate an Rx beam of a first beam pair associated with the BS and a Tx beam of a second beam pair associated with the UE to activate the downlink path, and / or may activate a Tx beam of a first beam pair associated with the BS and an Rx beam of a second beam pair associated with the UE to activate the uplink path.

[0089] In some aspects, the repeater configuration may indicate a gain parameter that the repeater is to use to relay or retransmit the RF analog signal during the duration indicated in the repeater configuration. In this case, a controller of the repeater (e.g., controller 330) may control a gain component (e.g., gain component 320, gain component 370, etc.) by controlling the level of amplification or gain applied by the gain component to the input signal when generating an output signal based at least in part on the gain parameter.

[0090] In some aspects, the repeater configuration may indicate one or more beamforming configurations, such as a transmit beamforming configuration and / or a receive beamforming configuration, that the repeater will use during the duration indicated in the repeater configuration. The transmit beamforming configuration may identify a codebook-based codeword index of a Tx beam associated with the BS and / or a Tx beam associated with the UE, one or more beamforming weights (e.g., phase shift coefficients, amplitude coefficients, etc.) to be applied to the Tx beam associated with the BS and / or the Tx beam associated with the UE, adjustments to one or more beamforming weights of the Tx beam associated with the BS and / or the Tx beam associated with the UE (e.g., adjustments to the phase shift and / or amplitude of the Tx beam associated with the BS and / or the Tx beam associated with the UE), and / or other beamforming parameters.

[0091] Similarly, the receive beamforming configuration may identify a codebook-based codeword index for an Rx beam associated with the BS and / or an Rx beam associated with the UE, one or more beamforming weights (e.g., phase shift coefficients, amplitude coefficients, etc.) to be applied to the Rx beam associated with the BS and / or the Rx beam associated with the UE, adjustments to one or more beamforming weights of the Rx beam associated with the BS and / or the Rx beam associated with the UE (e.g., adjustments to the phase shift and / or amplitude of the Rx beam associated with the BS and / or the Rx beam associated with the UE), and / or other beamforming parameters.

[0092] In some aspects, the relay configuration may indicate that the relay is to perform one or more measurements during a duration indicated in the relay configuration, and may indicate that the relay is to report the measurements to the BS during the duration and / or to store the measurements and report the measurements at another time. The one or more measurements may include one or more RSRP measurements, one or more RSSI measurements, one or more RSRQ measurements, one or more CQI measurements, etc. The relay configuration may indicate that the relay is to perform one or more measurements on one or more uplink communications received from the UE during the duration and / or on one or more downlink communications received from the BS during the duration.

[0093] In some aspects, the relay configuration may indicate that the relay will send one or more reference signals to the BS and / or UE during a duration indicated in the relay configuration. The one or more reference signals may include a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a sounding reference signal (SRS), and / or other types of reference signals.

[0094] like Figure 6B As shown, and by reference numeral 604, the relay may communicate with the BS and / or the UE based at least in part on one or more relay configurations received from the BS. In some aspects, the relay may communicate with the BS and / or the UE based at least in part on one or more configuration parameters indicated in the one or more relay configurations during one or more time durations indicated in the one or more relay configurations.

[0095] For example, a repeater may power on one or more components associated with the repeater and / or power off one or more components associated with the repeater for a duration indicated in the repeater configuration based at least in part on an indication in the repeater configuration to power on one or more components and / or power off one or more components.

[0096] As another example, if the repeater configuration indicates that the repeater activates an uplink path between the BS and the UE and / or a downlink path between the BS and the UE during the duration indicated by the repeater configuration, the repeater configuration may activate one or more Tx beams and / or Rx beams to activate the uplink path and / or the downlink path. In some aspects, the repeater may communicate with the BS and / or the UE via the uplink path by receiving an RF analog signal carrying uplink communications from the UE on the Rx beam and relaying or forwarding the RF analog signal to the BS on the Tx beam. In some aspects, the repeater may communicate with the BS and / or the UE on the downlink path by receiving an RF analog signal carrying downlink communications from the BS on the Rx beam and relaying or forwarding the RF analog signal to the UE on the Tx beam.

[0097] As another example, if the repeater configuration includes a receive beamforming configuration, the repeater may configure one or more Rx beams based at least in part on one or more configuration parameters identified in the receive beamforming configuration, and receive one or more communications (e.g., uplink communications and / or downlink communications) via the configured one or more Rx beams. As another example, if the repeater configuration includes a transmit beamforming configuration, the repeater may configure one or more Tx beams based at least in part on one or more configuration parameters identified in the transmit beamforming configuration, and receive one or more communications (e.g., uplink communications and / or downlink communications) via the configured one or more Tx beams.

[0098] As another example, if the relay configuration indicates that the relay will perform one or more measurements during a duration indicated in the relay configuration, the relay may perform one or more measurements for one or more uplink communications received from the UE and / or one or more downlink communications received from the BS during the duration. As another example, if the relay configuration indicates that the relay will send one or more reference signals during a duration indicated in the relay configuration, the relay may send one or more reference signals to the BS and / or UE during the duration.

[0099] As another example, if the repeater configuration indicates a gain parameter to be used during a duration indicated in the repeater configuration, the repeater may relay or forward uplink communications during the duration based at least in part on the gain parameter by amplifying received RF analog signals carrying uplink communications, and / or may relay or forward downlink communications during the duration based at least in part on the gain parameter by amplifying received RF analog signals carrying downlink communications.

[0100] Figure 6C-Figure 6E Various exemplary repeater configurations are illustrated. In some aspects, the exemplary repeater configurations may be implemented as a single repeater configuration, may be combined into a single repeater configuration, may be used to configure a repeater having a combination of multiple repeater configurations, etc. In addition, other repeater configurations may be configured and / or combined for use with a repeater. Figure 6C As shown, in some aspects, the exemplary relay configuration may include a relay configuration that the BS sends to the relay in a downlink control information (DCI) communication. In some aspects, the exemplary relay configuration may indicate that the relay will communicate with the BS and / or UE via an uplink path and / or a downlink path using one or more Tx and / or Rx beams.

[0101] like Figure 6CAs further shown in FIG. 1 , in some aspects, a DCI communication carrying a relay configuration may be sent by a BS or received by a relay at time T0. In some aspects, the exemplary relay configuration may indicate a start time (T-Start) of a duration for which the relay will communicate with the BS and / or UE based at least in part on one or more configuration parameters indicated in the relay configuration. For example, the exemplary relay configuration may indicate a start time (T-Start) of a duration for which the relay will communicate with the BS and / or UE by specifying a timing offset (T-Start) relative to T0. SΔ ) to explicitly specify T-Start or implicitly specify T-Start. In addition, the exemplary repeater configuration indicates the end time of the duration (T-End). For example, the exemplary repeater configuration can specify a timing offset (T-End) relative to T-Start. EΔ ) to specify T-End explicitly or implicitly.

[0102] like Fig.6D As shown, in some aspects, the exemplary repeater configuration may include multiple repeater configurations that the BS sends to the repeater in the DCI communication. In some aspects, each of the multiple exemplary repeater configurations may indicate that the repeater will use one or more Tx and / or Rx beams to communicate with the BS and / or UE via an uplink path and / or a downlink path. For example, the exemplary downlink repeater configuration may indicate that the repeater will use an Rx beam configured to communicate with the BS and a Tx beam configured to communicate with the UE to perform downlink communications with the BS and the UE via a downlink path. As another example, the exemplary uplink repeater configuration may indicate that the repeater will use a Tx beam configured to communicate with the BS and an Rx beam configured to communicate with the UE to perform uplink communications with the BS and the UE via an uplink path.

[0103] like Fig.6D As further shown in , in some aspects, a DCI communication carrying multiple exemplary repeater configurations may be sent by a BS or received by a repeater at time T0. The exemplary downlink repeater configuration may indicate a start time (T1-Start) of a first duration for which the repeater will communicate with the BS and / or UE based at least in part on one or more configuration parameters indicated in the exemplary downlink repeater configuration. For example, the exemplary downlink repeater configuration may explicitly specify T1-Start or implicitly specify T1-Start by specifying a timing offset relative to T0. In addition, the exemplary downlink repeater configuration may indicate an end time (T1-End) of the first duration. For example, the exemplary downlink repeater configuration may explicitly specify T1-End or implicitly specify T1-End by specifying a timing offset relative to T1-Start.

[0104] The exemplary uplink repeater configuration may indicate a start time (T2-Start) of a second duration during which the repeater will communicate with the BS and / or UE based at least in part on one or more configuration parameters indicated in the exemplary uplink repeater configuration.
