[0003] The following discussion pertains to wireless communication, including access point-assisted sidelink communication.

[0004] background

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A 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 can employ various technologies, 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 Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication from multiple communication devices, which may also be referred to as User Equipment (UE).

[0006] The first UE can be configured to communicate with the second UE using sidelink communication. However, for some use cases, sidelink communication may be limited. Reducing the limitations of sidelink communication or improving opportunities for sidelink communication may be beneficial.

[0007] Overview

[0008] The described technology relates to improved methods, systems, devices, and apparatuses supporting access point-assisted sidelink communication. Generally, the described technology provides an access point (AP) capable of configuring power parameters for sidelink communication between user equipment (UEs), including sidelink communication for UEs operating in low-power indoor (LPI) mode. The power parameters can be configured based on the operation of each UE within the AP's service area. In some examples, a first UE and a second UE can operate within the service area of ​​a first AP. Additionally or alternatively, the second UE can operate within the service area of ​​a second AP, different from the first AP. In some examples, the first AP can transmit one or more signals (e.g., anchor signals, synchronization signal blocks (SSBs), reference signals, or other signals, or any combination thereof) to the first UE, and the first UE can determine the power parameters based on the received signals (e.g., reference signal received power (RSRP) based on the received signals). Additionally or alternatively, the first UE can be configured to transmit one or more reference signals (e.g., probe reference signals (SRS)) to the first AP, and the first AP can configure the power parameters based on the received reference signals. The first AP may indicate power parameters in the sidelink configuration transmitted to the first UE. The sidelink configuration may indicate limits (e.g., maximum values) on one or more power parameters (such as power spectral density (PSD), equivalent isotropic radiated power (EIRP), etc.) for sidelink communication. The first UE may communicate with the second UE on the sidelink channel according to the sidelink configuration, which can improve the efficiency and reliability of sidelink communication and obtain other benefits.

[0060] Detailed description

[0061] Some wireless communication systems may include one or more wireless devices supporting one or more Radio Access Technologies (RATs), including fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems), fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems), and Wi-Fi systems (e.g., Wireless Local Area Network (WLAN) systems). For example, a wireless communication system may include user equipment (UE), base stations (such as next-generation B nodes or gigabit B nodes (either of which may be referred to as gNB)), integrated access and backhaul (IAB) nodes, repeaters (e.g., smart repeaters, dumb repeaters, radio frequency (RF) repeaters, etc.), sidelink nodes, relay nodes, etc.

[0062] In some wireless communication systems, UEs can be configured to communicate with each other via sidelink communication. However, in some cases, if the power parameters of the sidelink communication (such as power spectral density (PSD), equivalent isotropic radiated power (EIRP), etc.) are unrestricted, transmissions on the sidelink channel may interfere with communication between the UE and the base station (which may be referred to as Uu communication). Therefore, sidelink communication can be restricted to one or more RF bands (e.g., a radio frequency band close to 6 GHz) to reduce interference. For example, in Low Power Indoor (LPI) mode, UEs can be allowed to participate in sidelink communication indoors to help ensure that the UE's transmit power is low enough to avoid causing interference. In some cases, there may be concerns about allowing sidelink communication in LPI mode. For example, sidelink communication could enable UEs to operate outside the service area of ​​an authorized access point (AP), such as through a "daisy chain" connected via a sidelink. These concerns can be addressed by ensuring that the UE communicates directly with the AP. Thus, it may be beneficial to enable the AP to assist in configuring sidelink communication between UEs.

[0063] According to the techniques described herein, an AP can configure power parameters for sidelink communication between UEs (including sidelink communication for UEs operating in LPI mode). The power parameters can be configured based on the operation of each UE within the AP's service area. In some examples, a first UE and a second UE can operate within the service area of ​​a first AP. Additionally or alternatively, a second UE can operate within the service area of ​​a second AP, different from the first AP. In some examples, the first AP can transmit one or more signals to the first UE (e.g., anchor signal, synchronization signal block (SSB), reference signal, or another signal, or any combination thereof), and the first UE can determine the power parameters based on the received signals (e.g., reference signal received power (RSRP) based on the received signals). Additionally or alternatively, the first UE can be configured to transmit one or more reference signals to the first AP (e.g., probe reference signal (SRS)), and the first AP can configure the power parameters based on the received reference signals.

[0064] The first AP may indicate power parameters in the sidelink configuration transmitted to the first UE. The sidelink configuration may indicate limits (e.g., maximum values) on one or more power parameters (such as PSD, EIRP, etc.) for sidelink communication. Additionally or alternatively, the first UE may determine the power parameters based on the location of each UE indoors. The first UE may receive location information indicating that each UE is indoors (e.g., ultra-wideband positioning information, configuration, settings, or other location information). In some examples, the first UE may receive location information from one or more sensors, one or more actuators, or other mechanisms, or any combination thereof (such as mechanisms associated with indoor factory automation). The first UE may communicate with the second UE on the sidelink channel based on the power parameters, which can improve the efficiency and reliability of sidelink communication and obtain other benefits.

[0065] The aspects of this disclosure are initially described in the context of wireless communication systems. These aspects are further explained and described by way of process flows, apparatus diagrams, system diagrams, and flowcharts relating to access point-assisted sidelink communication.

[0066] Figure 1Examples of a wireless communication system 100 supporting access point-assisted sidelink communication according to various aspects of this disclosure are described. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, 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.

[0067] Base station 105 can be distributed across a geographical area to form wireless communication system 100, and can be different types of devices or devices with different capabilities. Base station 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. Coverage area 110 can be an example of a geographical area over which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0068] Each UE 115 can be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. Each UE 115 can be a different type of device or a device with different capabilities. Figure 1 The document describes some example UE 115s. The UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment). Figure 1 As shown in the image.

[0069] Each base station 105 may communicate with the core network 130, or with each other, or both. For example, base station 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 may communicate with each other directly (e.g., directly between base stations 105), indirectly (e.g., via the core network 130), or directly and indirectly on backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.

[0070] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base transceiver station, radio base station, AP, radio transceiver, B-node, evolved B-node (eNB), next-generation B-node or gigabit B-node (any of which may be referred to as gNB), home B-node, home evolved B-node, or other suitable terms. Additionally, and in some cases, the wireless communication system 100 may include an AP 106 for local area network communication within the service area 112.

[0071] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0072] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, as well as base stations 105, APs 106, and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown in the image.

[0073] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. Additionally or alternatively, UE 115 and AP 106 can wirelessly communicate with each other over a local area network via one or more communication links 125. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the radio spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. 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 can be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0074] 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 extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate the UE 115 can achieve. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can further improve the data rate or data integrity of communication with the UE 115.

[0075] The time intervals of base station 105, AP 106, or UE 115 can be expressed as multiples of a basic time unit, such as the sampling period T. s =1 / (Δf) max ·N f ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, while N fThis can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0076] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into several 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 several symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple mini-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier interval or the operating frequency band.

[0077] A subframe, time slot, mini-slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0078] Physical channels can be multiplexed on a carrier using various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier, for example, using one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search control regions for control information based on 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. An aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set configured to send control information to a specific UE 115.

[0079] Each base station 105 may provide communication coverage via one or more cells (e.g., macrocells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., on a carrier) and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or others). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. The extent of such cells may vary from smaller areas (e.g., structures, subsets of structures) to larger areas depending on various factors (such as the capabilities of base station 105). For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, among other examples.

[0080] Macrocells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs 115 that have service subscriptions with a network provider supporting the macrocell. Small cells may be associated with a lower-power base station 105 (compared to macrocells) and may operate in the same or different (e.g., licensed or unlicensed) frequency bands as macrocells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a home or office). 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. Similarly, AP 106 may support communication over a local network within service area 112 (which may be or include buildings, subsets of buildings, or areas associated with factory automation, etc.).

[0081] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0082] In some examples, base station 105 may be mobile, and thus provide communication coverage to mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage to various geographic coverage areas 110.

[0083] Some UE 115 devices (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 base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to people interacting with the application. Some UE 115 devices may be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wilderness survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial toll collection.

[0084] Some UEs 115 can be configured to operate in reduced-power modes, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a subcarrier or resource block (RB) set) within the carrier, within the carrier's guard band, or outside the carrier.

[0085] Wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private or group communication and may be supported by one or more mission-critical services, such as Mission-Critical Talk-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 general business applications. The terms ultra-reliable, low latency, mission-critical, and ultra-reliable low latency are used interchangeably herein.

[0086] In some examples, UE 115 may also be able to communicate directly with other UE 115 on sidelink communication link 135 (e.g., using client-to-client, peer-to-peer (P2P), or device-to-device (D2D) protocols). One or more UE 115s utilizing sidelink communication may be within the geographic coverage area 110 of base station 105 or the service area 112 of AP 106. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or may be unable to receive transmissions from base station 105 for other reasons. In some examples, groups of UE 115s communicating via sidelink communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 or AP 106 facilitates the scheduling of resources for sidelink communication. In other cases, sidelink communication is performed between the individual UE 115s without involving base station 105 or AP 106.

[0087] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC). The EPC or 5GC may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may be connected to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0088] Some network devices (such as base station 105) may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0089] Wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. Generally, the 300 MHz to 3 GHz band is referred to as a UHF band or decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can penetrate various structures sufficiently for macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the lower HF or VHF portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0090] Wireless communication system 100 may utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio spectrum bands, devices (such as base station 105 and UE 115) may employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands may be based on carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in licensed frequency bands. Operation in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0091] Base station 105, AP 106, or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105, AP 106, 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 examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 or AP 106 may have an antenna array with several rows and columns of antenna ports that base station 105 or AP 106 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0092] Base station 105, AP 106, or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique is known as spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0093] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, AP 106, or UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array, such that some signals propagating relative to a particular orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element may be defined by a beamforming weight set associated with a particular orientation (e.g., the antenna array relative to the transmitting or receiving device, or relative to some other orientation).

[0094] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer performs packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer performs priority handling and multiplexes logical channels into transport channels. The MAC layer can also use error detection, error correction, or both to support MAC layer retransmissions to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or core network 130 that support user plane data radio bearers. At the physical layer, transport channels can be mapped to physical channels.

[0095] UE 115, AP 106, and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of 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 can improve MAC layer throughput in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the devices may support simultaneous time-slot HARQ feedback, where the devices can provide HARQ feedback in a specific time slot for data received in previous symbols within that time slot. In other cases, the devices may provide HARQ feedback in subsequent time slots or according to some other time interval.

[0096] According to the techniques described herein, AP 106 can configure power parameters for sidelink communication (including sidelink communication for UE 115 operating in LPI mode) between each UE 115 (e.g., via sidelink communication link 135). The power parameters can be configured based on the operation of each UE within the AP service area 112. In some examples, the first UE 115 and the second UE 115 can operate within the service area 112 of the first AP 106. Additionally or alternatively, the second UE 115 can operate within the service area 112 of a second AP 106 different from the first AP 106. In some examples, the first AP 106 can transmit one or more signals to the first UE 115, and the first UE 115 can determine the power parameters based on the received signals (e.g., based on the RSRP of the received signals). Additionally or alternatively, the first UE 115 can be configured to transmit one or more reference signals to the first AP 106, and the first AP 106 can configure the power parameters based on the received reference signals. The first AP 106 may indicate power parameters in the sidelink configuration transmitted to the first UE 115. The sidelink configuration may indicate limits (e.g., maximum values) on one or more power parameters (such as PSD, EIRP, etc.) for sidelink communication. Additionally or alternatively, the first UE 115 may determine the power parameters based on the fact that each UE 115 is located indoors. For example, the first UE 115 may receive location information indicating that each UE 115 is located indoors. The first UE 115 may communicate with the second UE 115 on the sidelink channel 135 according to the power parameters, which may improve the efficiency and reliability of sidelink communication and obtain other benefits.

[0097] Figure 2 Examples of a wireless communication system 200 supporting access point-assisted sidelink communication according to various aspects of this disclosure have been described. In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100. For example, the wireless communication system 200 may include an AP 206 and one or more UEs 215, which may be referenced... Figure 1 Examples of corresponding devices described. The wireless communication system 200 may include features for improved sidelink communication between UEs 215, as well as other benefits.

[0098] AP 206 can communicate with each UE 215 via channels 220 (each of which may be referred to as a Uu interface). For example, AP 206 can communicate with UE 215-a via channel 220-a and with UE 215-b via channel 220-b. In some examples, channel 220 may be located in a radio spectrum band, such as an unlicensed National Information Infrastructure (U-NII) radio spectrum band with a carrier frequency close to 6 GHz (e.g., U-NII-4 band, U-NII-5 band, U-NII-6 band, U-NII-7 band, U-NII-8 band, or another radio spectrum band). AP 206 can communicate with UE 215 via channel 220 according to a configured operating mode (which may also be referred to as an adjustment mode), such as standard power mode, LPI mode, very low power (VLP) mode, etc.

[0099] UE 215-a and UE 215-b can operate within the service area 210 of AP 206. UE 215 can be configured to communicate via sidelink channel 225 depending on the operating mode. The operating mode used for sidelink communication via sidelink channel 225 can be the same as the configured mode used for communication via channel 220, or a different operating mode. However, in some cases, if the power parameters (such as PSD, EIRP, etc.) of sidelink communication are unrestricted, transmissions on sidelink channel 225 may interfere with communication between AP 206 and UE 215 on channel 220. In some cases, there may also be concerns about allowing sidelink communication between UE 215 in LPI mode. For example, sidelink communication could enable UE 215 to operate outside the service area 210 of AP 206, such as through a "daisy chain" of sidelink connections. These concerns can be addressed by ensuring that UE 215 communicates directly with AP 206 (e.g., via channel 220). Therefore, it may be beneficial for AP 206 to assist in configuring sidelink communication between each UE 215.

[0100] According to the techniques described herein, AP 206 can configure power parameters for sidelink communication between each UE 215 on sidelink channel 225. The power parameters can be configured based on the operation of each UE 215 within the service area 210 of AP 206. In some examples, the power parameters can be configured based on the fact that channel 220-a, channel 220-b, and sidelink channel 225 are the same channel (which may be referred to as channel 0). In some examples, the power parameters can be configured based on a first operating mode for communication via channel 220, a second operating mode for sidelink communication via sidelink channel 225, or both.

[0101] In some examples, AP 206 may transmit one or more signals (e.g., anchor signal, SSB, reference signal, or another signal, or any combination thereof) to UE 215-a, and UE 215-a may determine power parameters based on the received signals (e.g., based on the RSRP of the received signals). Additionally or alternatively, UE 215-a may be configured to transmit one or more reference signals (e.g., SRS) to AP 206, and AP 206 may configure power parameters based on the received reference signals.

[0102] AP 206 may indicate power parameters in the sidelink configuration transmitted to UE 215-a. The sidelink configuration may indicate limits (e.g., maximum values) on one or more power parameters (such as PSD, EIRP, etc.) for sidelink communication. Additionally or alternatively, UE 215-a may determine the power parameters based on each UE 215 being located indoors. UE 215-a may receive location information indicating that each UE 215 is located indoors. In some examples, UE 215-a may receive location information from one or more facilities associated with indoor factory automation. UE 215-a may communicate with UE 215-b via sidelink channel 225 based on the power parameters, which may improve the efficiency and reliability of sidelink communication and provide other benefits.

[0103] Figure 3 Examples of a wireless communication system 300 supporting access point-assisted sidelink communication according to various aspects of this disclosure are described. In some examples, the wireless communication system 300 may implement various aspects of the wireless communication system 100. For example, the wireless communication system 300 may include one or more APs 306 and one or more UEs 315, which may be referenced... Figure 1 Examples of corresponding devices described. The wireless communication system 300 may include features for improved sidelink communication between UEs 315, as well as other benefits.

[0104] Each AP 306 can communicate with each UE 315 via a channel 320 (each of which may be referred to as a Uu interface). For example, AP 306-a can communicate with UE 315-a via channel 320-a, and AP 306-b can communicate with UE 315-b via channel 320-b. In some examples, channel 320 can be in a radio spectrum band, such as the U-NII radio spectrum band with a carrier frequency close to 6 GHz. Each AP 306 can communicate with UE 315 via channel 320 according to a corresponding configured operating mode (such as standard power mode, LPI mode, VLP mode, etc.). The first operating mode associated with AP 306-a and the second operating mode associated with AP 306-b can be the same operating mode or different operating modes.

[0105] UE 315-a and UE 315-b can each operate within the service area 310 of AP 306. For example... Figure 3 As explained, UE 315-a can operate within the service area 310-a of AP 306-a, and UE 315-b can operate within the service area 310-b of AP 306-b. UE 315 can be configured to communicate via sidelink channel 325 according to a third operating mode. The third operating mode for sidelink communication via sidelink channel 325 can be the same as or different from the first or second operating modes for communication via channel 320. However, in some cases, if the power parameters (such as PSD, EIRP, etc.) of sidelink communication are unrestricted, transmissions on sidelink channel 325 may interfere with communication between AP 306 and UE 315 on channel 320. In some cases, there may also be concerns about allowing sidelink communication between UE 315 in LPI mode. For example, sidelink communication could enable UE 315 to operate outside the service area 310 of AP 306, such as via a "daisy chain" of sidelink connections. These concerns can be addressed by ensuring that UE 315 communicates directly with AP 306 (e.g., via channel 320). Therefore, it may be beneficial for AP 306 to assist in configuring sidelink communication between each UE 315.

[0106] According to the techniques described herein, AP 306 can configure power parameters for sidelink communication between each UE 315 over sidelink channel 325. The power parameters can be configured based on the operation of each UE 315 within the service area 310 of AP 306. In some examples, the power parameters can be configured based on a first operating mode for communication via channel 320-a, a second operating mode for communication via channel 320-b, a third operating mode for sidelink communication via sidelink channel 325, or any combination thereof.

[0107] In some examples, power parameters can be configured based on channel 220-a, channel 220-b, sidelink channel 225, and one or more RF bands including channel 220-a, channel 220-b, and sidelink channel 225. In some examples, channel 320-a, channel 320-b, and sidelink channel 325 can be the same channel, which may be referred to as channel 0. In some examples, channel 320-a, channel 320-b, and sidelink channel 325 are different channels. For example, channel 320-a can be channel 0, channel 320-b can be channel 1, and sidelink channel 325 can be channel 2. In some examples, channel 320-a, channel 320-b, and sidelink channel 325 can be in the same RF band (e.g., the U-NII band). In some examples, channel 320-a, channel 320-b, and sidelink channel 325 can be in different RF bands.

[0108] In some examples, AP 306-a may transmit one or more signals (e.g., anchor signal, SSB, reference signal, or another signal, or any combination thereof) to UE 315-a, and UE 315-a may determine power parameters based on the received signals (e.g., based on the RSRP of the received signals). Additionally or alternatively, UE 315-b may determine power parameters based on signals received from AP 306-b. In some examples, UE 315-a may be configured to transmit one or more reference signals (e.g., SRS) to AP 306-a, and AP 306-a may configure power parameters based on the received reference signals. Additionally or alternatively, AP 306-b may configure power parameters based on reference signals received from UE 315-b.

[0109] AP 306-a may indicate power parameters in the sidelink configuration transmitted to UE 315-a. The sidelink configuration may indicate limits (e.g., maximum values) on one or more power parameters (such as PSD, EIRP, etc.) for sidelink communication. Alternatively, UE 315-a may determine the power parameters based on each UE 315 being located indoors. UE 315-a may receive location information indicating that each UE 315 is located indoors. In some examples, UE 315-a may receive location information from one or more facilities associated with indoor factory automation. Alternatively, UE 315-b may determine the power parameters based on the sidelink configuration from AP 306-b or based on each UE 315 being located indoors. UE 315-a may communicate with UE 315-b via sidelink channel 325 according to the power parameters, which may improve the efficiency and reliability of sidelink communication and obtain other benefits.

[0110] Figure 4Examples of a process flow 400 supporting access point-assisted sidelink communication according to various aspects of this disclosure are described. In some examples, process flow 400 may implement one or more aspects of wireless communication systems 100, 200, or 300. For example, process flow 400 may include example operations associated with an AP 406 and one or more UEs 415, which may be referenced... Figures 1 to 3 Examples of the corresponding devices described. In the following description of process flow 400, operations between AP 406 and UE 415 may be performed in a different order than the example order shown, or operations performed by AP 406 and UE 415 may be performed in a different order or at different times. Some operations may also be omitted from process flow 400, and others may be added to process flow 400. Operations performed by AP 406 and UE 415 may support improvements in sidelink communication and, in some examples, may promote improvements in communication efficiency and obtain other benefits.

[0111] At 420, AP 406 may exchange signaling with UE 415-a on a first channel in the first RF band. In some examples, this signaling may include AP 406 transmitting an anchor signal, SSB, reference signal, or another signal, or any combination thereof, to UE 415-a. Additionally or alternatively, this signaling may include UE 415-a transmitting one or more reference signals to AP 406. In some examples, AP 406 may exchange signaling with UE 415-a according to a configured operating mode (such as standard power mode, LPI mode, VLP mode, etc.). In some examples, the exchanged signaling may indicate that UE 415-a and UE 415-b are in communication with an access point (such as AP 406 or another access point (not shown)).

[0112] At 425, AP 406 can determine one or more power parameters for sidelink communication between UE 415-a and UE 415-b on a second channel in a second RF band. These power parameters may include PSD, EIRP, another power parameter, or any combination thereof. In some examples, AP 406 may determine the power parameters based on signaling exchanged with UE 415-a.

[0113] At 430, AP 406 may transmit sidelink configuration for sidelink communication to UE 415-a. In some examples, the sidelink configuration may indicate determined power parameters, operating mode for sidelink communication, a second channel, a second RF band, or any combination thereof. In some examples, the sidelink configuration may be based on the exchanged signaling.

[0114] In 435, UE 415-a can determine the power parameters used for sidelink communication between UE 415-a and UE 415-b. In some examples, UE 415-a can determine the power parameters based on received sidelink configuration, exchanged signaling, or both.

[0115] In some examples, at 440, UE 415-a can determine the operating mode for sidelink communication. The operating mode can be standard power mode, LPI mode, VLP mode, or another operating mode. In some examples, UE 415-a can determine the operating mode based on received sidelink configuration, exchanged signaling, or both.

[0116] At 445, UE 415-a can communicate with UE 415-b on a second channel in a second RF band, depending on the sidelink configuration. The first and second channels can be the same channel or different channels. The first and second RF bands can be the same RF band (e.g., the U-NII band) or different RF bands. The operations performed by AP 406 and UE 415 can improve the efficiency and reliability of sidelink communication and obtain other benefits.

[0117] Figure 5 Examples of a process flow 500 supporting access point-assisted sidelink communication according to various aspects of this disclosure are described. In some examples, process flow 500 may implement one or more aspects of wireless communication systems 100, 200, or 300. For example, process flow 500 may include example operations associated with one or more UEs 515, which may be referenced... Figures 1 to 3 Examples of the corresponding devices described. In the following description of process flow 500, operations between the UEs 515 may be performed in a different order than the example order shown, or operations performed by the UEs 515 may be performed in a different order or at different times. Some operations may also be omitted from process flow 500, and others may be added to process flow 500. Operations performed by UE 515 may support improvements in side-link communication, and in some examples, may facilitate improvements in communication efficiency and obtain other benefits.

[0118] At 520, UE 515-a can determine the location information of UE 515-a and UE 515-b. In some examples, UE 515-a can receive location information indicating that each UE 515 is located indoors (e.g., UWB positioning information, configuration, settings, or other location information). In some examples, UE 515-a can receive location information from one or more sensors, one or more actuators, or other mechanisms, or any combination thereof (such as mechanisms associated with indoor factory automation).

By way of example and not limitation, non-transient computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compact disc (CD) ROM or other optical disc storage, magnetic disk storage or other magnetic storage devices, or any other non-transient medium that can be used to carry or store desired program code in the form of instructions or data structures and is accessible to a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Similarly, any connection is also legitimately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then that coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable media. As used in this article, disk and disc include CDs, laser discs, optical discs, DVDs, floppy disks, and Blu-ray discs, where disks often magnetically reproduce data while discs optically reproduce data using lasers. Combinations of these media are also included within the scope of computer-readable media.

[0272] As used herein (including in the claims), the word "or" in an enumeration of items (e.g., an enumeration of items accompanied by phrases such as "at least one of" or "one or more of") indicates an inclusive enumeration, such that an enumeration of at least one of, for example, A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Similarly, as used herein, the phrase "based on" should not be interpreted as referring to a closed set of conditions. For example, an example step described as "based on condition A" may be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0273] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, components of the same type may be distinguished by a dash following the reference numeral and a second reference numeral used to differentiate between similar components. If only the first reference numeral is used in the description, the description may apply to any of the similar components having the same first reference numeral, regardless of the second reference numeral or other subsequent reference numerals.

[0274] The descriptions herein, illustrated with reference to the accompanying drawings, depict exemplary configurations and are not representative of all examples that may be implemented or fall within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration" and does not imply "superior" or "outperforming" other examples. This detailed description includes specific details to provide an understanding of the described techniques. However, these techniques may be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form to avoid obscuring the concepts of the described examples.

[0275] The description provided herein is intended to enable those skilled in the art to make or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the universal principles defined herein can be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
