[0004] introduction

[0005] The following generally involves wireless communication, especially management-side link communication.

[0006] 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 with multiple communication devices, which may also be referred to as User Equipment (UE).

[0107] In some scenarios, a base station can communicate with a remote UE (e.g., a device outside the base station's coverage area or in a lower coverage area of ​​the base station) on a communication link comprising multiple links. For example, this communication link may include a sidelink between the remote UE and a relay UE (e.g., a device providing coverage to the remote UE within the base station's coverage area), and a relay link (e.g., a direct link) between the relay UE and the base station. In the uplink, the remote UE may transmit information (e.g., one or more data or control messages) to the relay UE on the sidelink, and the relay UE may relay or forward (e.g., transmit, retransmit) this information to the base station on the relay link. In the downlink, the base station may transmit information to the relay UE on the relay link, and the relay UE may relay or forward (e.g., transmit, retransmit) this information to the remote UE on the sidelink. The relay UE may also transmit its own information (e.g., one or more data or control messages originating from the relay UE) to the base station via the relay link (e.g., a direct link).

[0108] Some uplink transmissions originating from a remote UE, a relay UE, or both to a base station may be subject to one or more constraints. For example, when a remote UE or a relay UE receives uplink permission to allocate resources for uplink transmission (e.g., when a relay UE forwards or relays information from a remote UE), the remote UE or relay UE, or both, may use one or more constraints to determine how to multiplex information from different LCHs (e.g., communication channels associated with different types of information). Information associated with different LCHs may be assigned different scheduling priorities (e.g., priority of transmission to the base station), for example, such that information from a higher-priority LCH may be scheduled for transmission before information from other LCHs (e.g., relatively lower-priority LCHs). For example, a higher-priority LCH may be associated with higher-priority or lower-latency communications, or with communications from a relay UE, while a lower-priority LCH may be associated with lower-priority or higher-latency communications, or with communications from a remote UE.

[0109] In some examples of LCH limiting, the network may limit the LCH without using one or more uplink grants that have a duration longer than the threshold number of symbols or that have resources located on carriers in which the symbols are greater than the threshold width. In some examples, the limiting imposed on the LCH may be represented or referred to as LCP limiting. As described herein, LCP may refer to Logical Channel Priority or Logical Channel Priority Ordering. Methods or limiting configurations for configuring LCP limiting for communication links (e.g., sidelinks between remote UEs and relay UEs, and relay links between relay UEs and base stations) can support reduced communication latency and increased reliability.

[0110] After a communication link is established between a remote UE, a relay UE, and a base station, or as part of such a link, the base station may configure one or more LCP restrictions for that communication link. For example, the base station may configure LCP restrictions to distinguish information originating from the remote UE from information originating from the relay UE, restrict the remote UE to one or more communication resources (e.g., time and frequency resources), or restrict the link type (e.g., the type of channel or communication associated with the link) or TBS that can be used for the LCH at the remote UE or relay UE. The base station may determine the identity of the remote UE and may configure one or more LCP restrictions, for example, based on the identity of the remote UE. The base station may additionally or alternatively configure one or more LCP restrictions based on LCP restrictions already configured at one or both of the remote UE and the relay UE (e.g., nominal or initial LCP restrictions configured by the network).

[0111] A base station may (e.g., on a trunk link) transmit an indication of one or more LCP restrictions to a trunk UE, and a trunk UE may (e.g., on a sidelink link) transmit (e.g., forward or relay) an indication of the one or more LCP restrictions to a remote UE. The base station, remote UE, and trunk UE may communicate with each other on communication links (e.g., sidelink links and trunk links) based on the one or more LCP restrictions. For example, communication originating from a trunk UE may be given a priority over communication originating from a remote UE based on LCP restrictions, or may be associated with a priority offset. Similarly, communication from a remote UE or a trunk UE may be associated with one or more communication resources, one or more communication links, or one or more TBSs based on LCP restrictions.

[0112] The aspects of this disclosure are initially described in the context of wireless communication systems. These aspects are further illustrated and described by reference to LCP constraint configurations, process flows, apparatus diagrams, system diagrams, and flowcharts relating to the configuration of sidelink scheduling requests.

[0113] Figure 1 Examples of a channel-limited wireless communication system 100 supporting communication via a relay sidelink, according to one or more 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.

[0114] 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.

[0115] 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 1The 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.

[0116] 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. UE 115 may communicate with the core network 130 via communication link 155.

[0117] 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, access point, 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.

[0118] 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.

[0119] 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 station 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown in the image.

[0120] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. 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 may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0121] 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.

[0122] The time interval of base station 105 or UE 115 can be expressed as a multiple 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 f This 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).

[0123] 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.

[0124] 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)).

[0125] 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 hybrid TDM-FDM techniques. 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 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 particular UE 115.

[0126] 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)).

[0127] 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.

[0128] 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.

[0129] In some examples, UE 115 may also be able to communicate directly with other UE 115 on device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). In some cases, communication link 135 may be referred to as a sidelink communication link and may be used for sidelink communication between the various UEs 115. In some cases, the sidelink communication link as described herein may additionally or alternatively represent an example of relay link 165, wherein relay link 165 may be used to relay information (e.g., data, control information) from a first UE 115 to a second UE 115. In some cases, relay link may additionally or alternatively be an example of communication link 135.

[0130] One or more UEs 115 using D2D or sidelink communication may be within the geographic coverage area 110 of base station 105. Other UEs 115 in this 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 UEs 115 communicating via D2D or 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 facilitates the scheduling of resources for D2D or sidelink communication. In other cases, D2D or sidelink communication is performed between the UEs 115 without involving base station 105.

[0131] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may use vehicle-to-network (V2N) communication via one or more network nodes (e.g., base station 105) to communicate with roadside infrastructure (such as roadside units), or with the network, or with both. In some cases, V2V communication may be implemented using a PC5 interface.

[0132] 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 can be connected to network operator IP service 150. Carrier IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0133] 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).

[0134] Wireless communication system 100 can operate using one or more frequency bands in the range of, for example, 300 MHz to 300 GHz. A 300 MHz to 3 GHz band may be referred to as a UHF band or decimeter band because the wavelengths range from about 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 high frequency (HF) or very high frequency (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).

[0135] The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is generally (interchangeably) referred to as the “sub-6GHz band” in various documents and articles. Similar naming issues sometimes arise with FR2; although different from the Very High Frequency (EHF) band (30GHz–300GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is generally (interchangeably) referred to as the “millimeter wave” band in various documents and articles.

[0136] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands of these IF bands as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 into the IF band. Additionally, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating frequency bands have been designated as the frequency range designations FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0137] In light of the foregoing, unless otherwise stated, it should be understood that, as used herein, the term "sub-6GHz" and the like can broadly refer to frequencies less than 6GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise stated, it should be understood that, as used herein, the term "millimeter wave" and the like can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a or FR4-1 and / or FR5, or within the EHF band.

[0138] 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.

[0139] Base station 105 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 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 coexist 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 may have an antenna array with several rows and columns of antenna ports that base station 105 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.

[0140] Base station 105 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 may transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports 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.

[0141] 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, 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).

[0142] 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 can perform packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer can perform priority handling and multiplexing 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.

[0143] UE 115 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 correct data reception 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 device may support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in previous symbols within that time slot. In other cases, the device may provide HARQ feedback in subsequent time slots or according to some other time interval.

[0144] In some wireless communication systems, base station 105 can communicate with remote UE 115 over an indirect communication link. For example, remote UE 115 and base station 105 can communicate via a sidelink between remote UE 115 and relay UE 115, and a relay link (e.g., a direct link) between relay UE 115 and base station 105. In the uplink, remote UE 115 can transmit information (e.g., one or more messages) to relay UE 115 on the sidelink, and relay UE 115 can relay or forward (e.g., transmit) that information to base station 105 on the relay link. In the downlink, base station 105 can transmit information to relay UE 115 on the relay link, and relay UE 115 can relay or forward (e.g., transmit) that information to remote UE 115 on the sidelink.

[0145] In some scenarios, relay UE 115 may support similar communication links with multiple remote UEs 115 for communication with base station 105. The communication link between remote UE 115, relay UE 115, and base station may represent Layer 2 relay (e.g., UE-to-network relay). Remote UE 115 may discover relay UEs before establishing a communication link, for example, using a discovery procedure based on one or more relay service codes, which may be configured by the network or provided to remote UE 115 by a policy control function (PCF) during registration with base station 105 (e.g., when establishing a Uu link). Remote UE 115 may discover relay UE 115 by monitoring one or more corresponding relay service codes. During link establishment, relay UE 115 may establish a dedicated protocol data unit (PDU) session associated with one or more relay service codes.

[0146] In some scenarios, the network can maintain aggregation protocols on the communication links between base station 105, relay UE 115, and remote UE 115, and can restrict the aggregation protocols between relay UE 115 and remote UE 115. Network access layer and non-access layer connections can also be maintained on the communication links. In one scenario, the radio access network (RAN) can use network RRC signaling to control sidelinks (e.g., PC5 interfaces).

[0147] Some uplink transmissions from remote UE 115, relay UE 115, or both to base station 105 may be subject to one or more restrictions. Methods or restriction configurations for configuring LCP restrictions on communication links, including sidelinks between remote UE 115 and relay UE 115, and relay links between relay UE 115 and base station 105, can support reduced communication latency and increased reliability. Base station 105 may configure one or more LCP restrictions accordingly for the communication link. For example, base station 105 may configure LCP restrictions to differentiate information originating from remote UE 115 and relay UE 115, restrict remote UE 115 to one or more resources, or restrict the link type or TBS that can be used on the LCH at remote UE 115 or relay UE 115. Base station 105 may determine the identity of remote UE 115 (e.g., as part of establishing a communication link) and may configure one or more LCP restrictions based on the identity of remote UE 115. Base station 105 may further configure one or more LCP limits based on LCP limits configured at one or both of the remote UE 115 and the relay UE 115 (e.g., nominal or initial LCP limits configured by the network).

[0148] Base station 105 may (e.g., on a trunk link) transmit an indication of one or more LCP restrictions to trunk UE 115, and trunk UE 115 may (e.g., on a side link) transmit (e.g., forward or relay) an indication of the one or more LCP restrictions to remote UE 115. Base station 105, remote UE 115, and trunk UE 115 may communicate with each other on communication links (e.g., side links and trunk links) based on the one or more LCP restrictions. For example, communication originating from trunk UE 115 may take a priority over communication originating from remote UE 115 based on LCP restrictions, or may be associated with a priority offset. Similarly, communication from remote UE 115 or trunk UE 115 may be associated with one or more resources, one or more communication links, or one or more TBSs based on LCP restrictions.

[0149] One or more of the operations performed by base station 105 may be performed by base station communication manager 102, which may be as described in reference Figures 9 to 12 Examples of the described communication managers 915, 1015, 1105, or 1210. In some cases, the transceiver can perform receive or transmit operations, and the scheduler can determine one or more LCP limits.

[0150] One or more of the operations performed by the remote UE 115 or the relay UE 115 may be performed by the UE communication manager 101, which may be as described in reference to Figures 5 to 8 Examples of the described communication managers 515, 615, 705, or 810. In some cases, the transceiver can perform receive or transmit operations, and the processor can identify one or more aspects of the LCP limit configuration and configure one or more communications according to that LCP limit configuration.

[0151] Figure 2 Examples of a wireless communication system 200 supporting channel-limited communication via a relay sidelink, according to one or more aspects of this disclosure, are described. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a base station 105-a, a UE 115-b, and a UE 115-a, which may be as described in reference... Figure 1 Examples of base station 105 and UE 115 described herein. Base station 105-a may communicate with UE 115-b on a direct communication link and may communicate with UE 115-a on an indirect communication link, wherein UE 115-a may represent a remote UE 115 and UE 115-b may represent a relay UE 115.

[0152] For example, UE 115-a and base station 105-a can communicate via a sidelink between UE 115-b and UE 115-a, and a relay link (e.g., a direct link or a Uu link) between UE 115-b and base station 105-a. In the uplink, UE 115-a can transmit information (e.g., one or more messages) to UE 115-b on the sidelink, and UE 115-b can relay or forward that information to base station 105-a on the relay link. In the downlink, base station 105-a can transmit information to UE 115-b on the relay link, and UE 115-b can relay or forward that information to UE 115-a on the sidelink.

[0153] In some scenarios, UE 115-a may be located outside the coverage area of ​​base station 105-a and may communicate with base station 105-a via a communication link with UE 115-b (e.g., an indirect communication link). In other scenarios, UE 115-a may be located within the coverage area of ​​base station 105-a and may establish a direct communication link with base station 105-a (e.g., a Uu link) (e.g., as a supplement to the indirect communication link). In such scenarios, UE 115-a may communicate with base station 105-a via a communication link with UE 115-b, via a direct communication link, or both. UE 115-a may use two links to increase communication throughput and robustness. For example, smaller uplink control information (UCI) packets may be transmitted directly to base station 105-a on the direct link, but larger UCI packets may be transmitted via UE 115-b (e.g., where the link via UE 115-b has higher throughput).

[0154] For uplink transmissions from UE 115-a to base station 105-a over an indirect communication link, base station 105-a may dynamically schedule uplink resources on the sidelink link between UE 115-b and UE 115-a. It may pre-configure one or more uplink grants or resources for the sidelink link, or it may omit scheduling or configuring any uplink resources (e.g., UE 115-b and UE 115-a may schedule uplink resources for the sidelink link). Uplink transmissions on the relay link between UE 115-b and base station 105-a may include a shared MAC instance between UE 115-b and any remote UE 115 (e.g., including UE 115-a) communicating with base station 105-a via UE 115-b, or may include separate MAC instances for different remote UE 115s (e.g., one MAC instance may be configured for UE 115-a).

[0155] Remote UEs 115 communicating with base station 105-a via UE 115-b (e.g., including UE 115-a) can be organized into one or more UE 115 groups or sets of UE 115s. In the first example, remote UEs 115 communicating with base station 105-a via UE 115-b can be organized into multiple groups, and UE 115-b can be included in one or more of these groups. UEs 115 within each group can share a common MAC instance and RLC procedure (e.g., their RLC PDUs can be multiplexed in the same MAC PDU). Communication traffic for UEs 115 in different groups can be restricted without mixing (e.g., without multiplexing) and can be scheduled separately. In some cases, all UEs 115 (e.g., including UE 115-a and UE 115-b) may be included in a single group, and in other cases, UE 115-b itself may be included in a group, while all remote UEs 115 (e.g., including UE 115-a) may be included in another group. In the second example, the remote UEs 115 communicating with base station 105-a via UE 115-b may be organized into groups of one UE 115 per group. UE 115-b may also be included in one of these groups (e.g., it may be included in its own group).

[0156] Data for uplink transmission can reach the buffer of UE 115-a, which can trigger a buffer status report (BSR) if the buffer is empty when the data arrives or if the data has a higher priority than other data on other logical channels. In cases where uplink transmission on a relay or sidelink is dynamically scheduled by base station 105-a, the BSR may represent or include a request to base station 105-a for sidelink or other resources used for data transmission. If sidelink resources are available for transmitting the BSR, or if sidelink resources (e.g., Physical Sidelink Control Channel (PSCCH) resources) are pre-configured for the BSR, UE 115-a may transmit the BSR to UE 115-b on at least a portion of the available sidelink resources. UE 115-b may forward or relay the BSR to base station 105-a, and base station 105-a may configure or grant uplink resources (e.g., resources on sidelinks and / or relay links) for data transmission based on the received BSR. In some cases, the method for transmitting a BSR from UE 115-b to base station 105-a may be based on the method for transmitting a BSR from UE 115-a to base station 105-a.

[0157] Some uplink transmissions (e.g., BSR, uplink data, control information) from UE 115-a, UE 115-b, and both to base station 105-a may be subject to one or more restrictions. For example, UE 115-a or 115-b may use one or more restrictions to determine how to multiplex information from different LCHs when either UE 115 receives uplink permission (e.g., when UE 115-b forwards or relays information from UE 115-a). Information from different LCHs may be assigned different scheduling priorities, for example, so that data from a higher-priority LCH may be scheduled for transmission before messages from other LCHs. In some examples of LCH restrictions, the network may restrict the LCH from using one or more uplink permissions that may be associated with one or more attributes. For example, an LCH associated with URLLC communication may be restricted from using uplink permissions with a duration longer than a threshold number of symbols or resources located on a carrier with a parameter design greater than a threshold width. In some examples, restrictions imposed on the LCH may be represented or referred to as LCP restrictions.

[0158] If LCP restrictions are not available or assigned for transmissions on communication links including remote UE 115 (e.g., UE 115-a) and relay UE 115 (e.g., UE 115-b), uplink transmissions from UE 115-a, UE 115-b, or both may be delayed or have a lower Quality of Service (QoS). Therefore, methods or restriction configurations for communication on such links (such as sidelinks between UE 115-b and UE 115-a, and relay links between UE 115-b and base station 105-a) can support reduced communication latency and increased QoS.

[0159] This disclosure provides methods and restriction configurations for communication on a communication link including a remote UE 115, a relay UE 115, and a base station 105 (e.g., UE 115-a, UE 115-b, and base station 105-a, respectively). After a communication link is established between UE 115-a, UE 115-b, and base station 105-a, or as part of such a link, base station 105-a may configure one or more LCP restrictions for that communication link. For example, base station 105-a may configure LCP restrictions to differentiate information originating from UE 115-a and UE 115-b, limit UE 115-a (e.g., or a group of remote UE 115s including UE 115-a) to one or more resources, or restrict the link type or TBS that can be used on the LCH at UE 115-a or UE 115-b.

[0160] Base station 105-a can determine the identity of UE 115-a (e.g., as part of establishing a communication link) and can configure one or more LCP restrictions based on the identity of UE 115-a. In some cases, base station 105-a can determine the identity of UE 115-b (e.g., as part of establishing a communication link) and can configure one or more LCP restrictions based on the identity of UE 115-b. For example, UE 115-a may transmit an indication of the ID associated with UE 115-a to UE 115-b in uplink message 205-a (e.g., when establishing a communication link). UE 115-b may transmit the ID of UE 115-a and / or the ID associated with UE 115-b to base station 105-a in uplink message 205-b.

[0161] In some cases, base station 105-a may further configure one or more LCP limits based on LCP limits configured at one or both of UE 115-a and UE 115-b (e.g., nominal or initial LCP limits configured by the network). For example, UE 115-a may transmit an indication of one or more LCP limits associated with UE 115-a to UE 115-b in uplink message 205-a. UE 115-b may transmit the LCP limits of UE 115-a and / or one or more LCP limits associated with UE 115-b to base station 105-a in uplink message 205-b.

[0162] In some scenarios (e.g., when all remote UEs 115 and UE 115-b can share the same group), base station 105-a can configure LCP restrictions to give information from UE 115-b a scheduling priority that takes precedence over information from UE 115-a (e.g., and over information from other remote UEs 115). For example, the LCH of UE 115-b and the LCH of UE 115-a can have the same nominal priority value (e.g., configured by the network), and base station 105-a can schedule UE 115-b first based on LCP restrictions (e.g., the higher priority associated with UE 115-b). In some scenarios, base station 105-a can configure offset priority values ​​for information originating from UE 115-b such that the priority value of such information is equal to the original (e.g., nominal) priority value configured by the network plus the offset priority value.

[0163] In the first example, UE 115-b can be configured with a nominal priority value '1', UE 115-a can be configured with a nominal priority value '2', and the LCP limit can indicate an offset priority value '2'. Thus, the priority value of information originating from UE 115-b can represent the nominal priority value plus an offset, or that is, the value '3'. In this example, information from UE 115-b can have a higher priority value than information from UE 115-a, and base station 105-a can schedule UE 115-b first based on the LCP limit (e.g., offset) and the nominal priority value. In the second example, UE 115-b can be configured with a nominal priority value '1', UE 115-a can be configured with a nominal priority value '2', and the LCP limit can indicate an offset priority value '1'. Thus, the priority value of information originating from UE 115-b can represent the nominal priority value plus an offset, or that is, the value '2'. In this example, information from UE 115-b may have the same priority value as information from UE 115-a, and base station 105-a may share scheduling resources equally between the LCHs of UE 115-b and UE 115-a based on LCP limits (e.g., offset) and nominal priority values.

[0164] LCP restrictions can additionally or alternatively limit communication to or from UE 115-a (e.g., or a group of remote UE 115s including UE 115-a) to a subset of carriers on the system bandwidth or resources associated with dynamic grants. For example, UE 115-a (e.g., or a group of remote UE 115s) can be prohibited from using configured grants (e.g., type 1 granted grants) to avoid increased resource contention. In some cases, UE 115-a may be located within the coverage area of ​​base station 105-a and may establish a direct link with base station 105-a. In such cases, LCP restrictions can configure the association or restriction between the LCH and different link types (e.g., sidelink or direct link types), or can configure the TBS range for different link types and associated LCHs. Such restrictions are further referenced herein. Figure 3 To describe.

[0165] Base station 105-a may (e.g., on a relay link) transmit an indication 210-a of one or more LCP restrictions to UE 115-b, and UE 115-b may (e.g., on a side link) transmit (e.g., forward or relay) an indication 210-b of one or more LCP restrictions to UE 115-a. Base station 105-a, UE 115-a, and UE 115-b may communicate with each other on communication links (e.g., side links and relay links) based on the one or more LCP restrictions. For example, as described herein, communication originating from UE 115-b may be given a priority over communication originating from UE 115-a based on LCP restrictions or may be associated with a priority offset. Similarly, communication from UE 115-a may be associated with one or more resources, one or more communication links, or one or more TBSs based on LCP restrictions.

[0166] In one or more aspects, the described techniques can support improvements in wireless communication. For example, one or more LCP limits (e.g., LCP limits associated with the communication link) of UE 115-a and UE 115-b can support reduced communication latency and increased reliability.

[0167] Figure 3 Examples of LCP restriction configuration 300 supporting channel restriction for communication via a relay sidelink, according to one or more aspects of this disclosure, are described. In some examples, LCP restriction configuration 300 may be implemented by or by aspects of wireless communication system 100 or 200. For example, base station 105 may be configured with LCP restriction configuration 300 for communicating with remote UE 115 via a first communication link 310, the first communication link including a relay UE 115 for relaying communications to and from remote UE 115. Base station 105 may transmit an indication of LCP restriction configuration to relay UE 115, and relay UE 115 may forward or transmit the indication to remote UE 115, as referred to Figure 2 As described herein, base station 105 and UE 115 may be referenced herein. Figure 1 and 2 Examples of base station 105 and UE 115 described.

[0168] For reference Figure 2As described, in some scenarios, base station 105 and remote UE 115 may communicate on a second direct communication link 310 between remote UE 115 and base station 105 (e.g., if remote UE 115 is located within the coverage area of ​​base station 105). Base station 105 may configure LCP restrictions for remote UE 115 (e.g., LCP restriction configuration 300) such that the LCP restriction may specify the association between the remote UE 115's LCH 305 and one or more communication links 310 and / or may specify a TBS threshold 315 or 320 on the communication link 310. It will be understood that although LCP restrictions are described with respect to remote UE 115, such LCP restrictions may also be configured for or applied to relay UE 115.

[0169] In one example, base station 105 may configure LCP restrictions for a remote UE 115 for use with the first LCH 305-a, the second LCH 305-b, and so on up to the nth LCH 305-c. Base station 105 may associate each LCH 305 with one or more communication links 310. For example, base station 105 may specify whether uplink permission to a direct communication link 310 (e.g., a second communication link 310) is available for each LCH 305. For example, an LCH 305 used by an eMBB application may be associated with higher throughput, and base station 105 may restrict such LCH 305 from using the direct communication link 310. Additionally or alternatively, LCH 305s with lower latency constraints may be restricted from using the first communication link (e.g., included at the relay UE 115). In one example, base station 105 may specify that direct communication link 310 may be used on LCH 305-a and 305-c and / or may restrict the direct communication link from being used on LCH 305-b. In this example, base station 105 may further specify that the first communication link 310 (e.g., a relay link) may be used on LCH 305-a and 305-b and / or may restrict the first communication link from being used on LCH 305-c.

[0170] Base station 105 may further associate each LCH 305 with one or more TBS thresholds 315 or 320 for each supported communication link 310. In one example, TBS threshold 315 may be associated with a first communication link 310, while TBS threshold 320 may be associated with a second communication link 310 (e.g., a direct communication link 310). In some cases, TBS thresholds 315 or 320 may include the range of TBS that a remote UE 115 can support on the respective communication link 310. For example, base station 105 may configure a threshold TBS (e.g., minimum TBS) for LCH 305 supporting the first communication link 310. For example, this configuration may avoid wasting resources on high-throughput applications (e.g., eMBB). Base station 105 may additionally or alternatively configure a threshold TBS (e.g., maximum TBS) for LCH 305 supporting the second direct communication link 310. For example, this configuration can support high reliability and low latency applications (e.g., URLLC) because a smaller TBS can be associated with a lower number of retransmissions.

[0171] In one example, base station 105 may specify a first TBS threshold 315-a for communication link 310-a on LCH 305-a and a first TBS threshold 320-a for communication link 310-b on LCH 305-a. The first TBS threshold 315-a may include a minimum TBS, while the first TBS threshold 320-a may include a maximum TBS. Base station 105 may further specify a second TBS threshold 315-b for communication link 310-c on LCH 305-b and a second TBS threshold 320-b for communication link 310-d on LCH 305-c. The second TBS threshold 315-a may include a minimum TBS, while the second TBS threshold 320-a may include a maximum TBS. In some cases, the first TBS threshold 315-a and the second TBS threshold 315-b may be different, or in some cases, the TBS threshold 315 may be the same. Similarly, the first TBS threshold 320-a and the second TBS threshold 320-b can be different or the same.

[0172] Base station 105 may (e.g., on a trunk link) transmit an indication of LCP restriction configuration 300 to trunk UE 115, and trunk UE 115 may (e.g., on a side link) transmit (e.g., forward or relay) an indication of LCP restriction configuration 300 to remote UE 115. Base station 105, remote UE 115, and trunk UE 115 may communicate with each other on communication links (e.g., side links and trunk links) based on LCP restriction configuration 300. For example, communication associated with different LCH 305 of remote UE 115 (e.g., directed to base station 105 and / or trunk UE 115) may be associated with one or more communication links 310 or one or more TBSs based on LCP restriction configuration 300.

[0173] Figure 4 Examples of a process flow 400 supporting channel limiting for communication via a relay sidelink, according to one or more aspects of this disclosure, are described. In some examples, process flow 400 may be implemented by or by aspects of wireless communication systems 100 or 200. In some cases, process flow 400 may be implemented by or by aspects of LCP limiting configuration 300. The process flow may be implemented by base station 105-b, UE 115-c, and UE 115-d, wherein UE 115-c may represent a remote UE 115 and UE 115-d may represent a relay UE 115. Base station 105-b, UE 115-c, and UE 115-d may represent, as referred to herein, a remote UE 115. Figure 1-3 Examples of base station 105 and UE 115 described herein. Base station 105-b may communicate with UE 115-c via a communication link including (e.g., for relaying communications to or from UE 115-c) UE 115-d.

[0174] In the following description of process flow 400, operations between UE 115-c, UE 115-d and base station 105-b may be transmitted in a different order than shown, or operations performed by UE 115-c, UE 115-d and base station 105-b may be performed in a different order or at different times. Some operations may also be excluded from process flow 400, or other operations may be added to process flow 400. Although UE 115-c, UE 115-d and base station 105-b are shown performing operations of process flow 400, some aspects of some operations may also be performed by one or more other wireless devices. For example, UE 115-c and UE 115-d may each represent a corresponding example of a wireless communication device, which may or may not be UE 115.

[0175] At 405, base station 105-b, UE 115-c, and UE 115-d can establish a communication link, which may include a sidelink between UE 115-c and UE 115-d and a relay link between UE 115-d and base station 105-b. In some cases, when establishing a communication link, UE 115-d may transmit the ID of UE 115-c (e.g., received from UE 115-c) and / or the ID of UE 115-d to base station 105-b.

[0176] In 410-a, in some cases, UE 115-c may transmit an indication to UE 115-d in an uplink message regarding one or more LCP restrictions (e.g., initial LCP restrictions) configured by the network and associated with UE 115-c. In 410-b, in some cases, UE 115-d may, for example, transmit the LCP restrictions of UE 115-c and / or one or more LCP restrictions (e.g., initial LCP restrictions) configured by the network and associated with UE 115-d to base station 105-b in an uplink message.

[0177] At 415, base station 105-b can determine the identity of UE 115-c (e.g., based on establishing a communication link) and can determine one or more LCP restrictions corresponding to the communication link based on the identity of UE 115-c. Base station 105-b can also determine one or more LCP restrictions based on LCP restrictions configured by the network for UE 115-c and UE 115-d. For example, as referenced herein... Figure 2 and 3 As described, base station 105-b may be configured with one or more LCP restrictions to differentiate information originating from UE 115-c and UE 115-d, restrict UE 115-c (e.g., or a group of remote UE 115s including UE 115-c) to one or more resources, or restrict the link type or TBS that can be used on the LCH at UE 115-c or UE 115-d.

[0178] In 420-a, base station 105-b may transmit an indication of the restriction on one or more LCPs to UE 115-d over the relay link. In some cases, the indication may include, as referenced... Figure 3 The described LCP restriction configuration includes one or more aspects.

[0179] In 420-b, UE 115-d may transmit an indication of the one or more LCP restrictions to UE 115-c on the sidelink. In some cases, this indication may include, as referenced... Figure 3 The described LCP restriction configuration includes one or more aspects.

[0180] In 425, base station 105-b, UE 115-c, and UE 115-d can communicate with each other on communication links (e.g., sidelinks and trunk links) based on one or more LCP restrictions. For example, as described herein, communication originating from UE 115-d can be given a priority over communication originating from UE 115-c based on one or more LCP restrictions, or can be associated with a priority offset. Similarly, communication from UE 115-c or UE 115-d can be associated with one or more resources, one or more communication links, or one or more TBSs based on LCP restrictions.

[0181] In some scenarios, UE 115-c may trigger a BSR for transmitting data to base station 105-b on the communication link. For example, UE 115-c may identify or receive data in its buffer and may trigger a BSR based on the identified data (e.g., based on whether the identified data is new data or based on the priority of the identified data).

[0182] Figure 5 A block diagram 500 of an apparatus 505 supporting channel-limited communication via a relay sidelink, according to one or more aspects of this disclosure, is shown.

Each of these components may be in communication with each other (e.g., via one or more buses).

[0183] Receiver 510 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to channel restrictions for communication via relay sidelinks). The information can be transmitted to other components of device 505. Receiver 510 can be a reference... Figure 8 Examples of various aspects of the transceiver 820 described. The receiver 510 may utilize a single antenna or an array of antennas.

[0184] The communication manager 515 can receive, on a relay communication link between the first device and the base station, an indication of one or more LCP restrictions corresponding to the relay communication link and a sidelink communication link between the first device and the second device, the one or more LCP restrictions being based on the identity of the second device. The communication manager 515 can transmit the indication of the one or more LCP restrictions on the sidelink communication link; and conduct communication on the sidelink communication link and the relay communication link based on the one or more LCP restrictions.

[0185] Additionally or alternatively, the communication manager 515 may receive indications of one or more LCP restrictions corresponding to the sidelink communication link between the second device and the first device, and the relay communication link between the first device and the base station, the one or more LCP restrictions being based on the identity of the second device. The communication manager 515 may communicate on the sidelink communication link based on the one or more LCP restrictions. The communication manager 515 may be an example of various aspects of the communication manager 810 described herein.

[0186] The communication manager 515 may be an example of a means for performing various aspects of management sidelink communication as described herein. The communication manager 515 or its sub-components may be implemented in hardware (e.g., in a communication management circuitry system). This circuitry system may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein.

[0187] In another implementation, the communication manager 515 or its subcomponents may be implemented in processor-executable code (e.g., as communication management software or firmware) or any combination thereof. If implemented in processor-executable code, the functionality of the communication manager 515 or its subcomponents may be executed by a general-purpose processor, DSP, ASIC, FPGA, or other programmable logic device.

[0188] In some examples, the communication manager 515 may be configured to use or otherwise cooperate with the receiver 510, the transmitter 520, or both to perform various operations (e.g., receiving, transmitting, communicating).

[0189] The communication manager 515 or its subcomponents may be physically located at various locations, including being distributed such that portions of the functionality are implemented by one or more physical components at different physical locations. In some examples, according to various aspects of this disclosure, the communication manager 515 or its subcomponents may be separate and distinct components.

For example, transmitter 520 may be a reference... Figure 8Examples of various aspects of the transceiver 820 described. The transmitter 520 may utilize a single antenna or an array of antennas.

[0191] In one or more aspects, the described techniques performed by the communication manager 515 as described herein can support improvements in communication via relay-side links. For example, the communication manager 515 can reduce communication latency and latency and increase available power at the radio device (e.g., UE 115) by supporting LCP limits imposed on the communication link between the remote UE, relay UE, and base station. Compared to other systems and techniques (e.g., other systems and techniques that do not support LCP limit configuration for the communication link between the remote UE, relay UE, and base station), LCP limits can reduce overhead resource usage or power consumption at the device (or any combination thereof). Accordingly, the communication manager 515 can save power and increase battery life at the radio device (e.g., UE 115) by strategically reducing the amount of signaling or processing performed by the radio device (e.g., UE 115) when communicating on the communication link between the remote UE, relay UE, and base station.

[0193] Receiver 610 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to channel restrictions for communication via relay sidelinks). The information can be transmitted to other components of device 605. Receiver 610 can be a reference... Figure 8 Examples of various aspects of the transceiver 820 described.

[0198] The processor of the wireless device (e.g., controls receiver 610, transmitter 645, or as per reference) Figure 8 The described transceiver 820 can reduce communication latency and latency and increase available power. Compared with other systems and technologies (e.g., other systems and technologies that do not support LCP-limited configuration for communication links between remote UEs, relay UEs, and base stations), the reduced latency can reduce energy consumption (e.g., via implementation reference). Figure 7 (The system components described herein). Furthermore, the processor of UE 115 may identify one or more aspects of the LCP restriction configuration to perform the techniques described herein. The processor of the radio device may use the LCP restriction configuration to perform one or more actions that result in lower latency and power consumption, as well as power savings and increased battery life at the radio device (e.g., by communicating according to one or more link-specific LCP restrictions on the communication link between the remote UE, the relay UE, and the base station), and other improvements.

[0408] While aspects of LTE, LTE-A, LTE-A Pro, or NR systems may be described for illustrative purposes, and the terms LTE, LTE-A, LTE-A Pro, or NR may be used in most of the description, the techniques described herein can also be applied to networks other than LTE, LTE-A, LTE-A Pro, or NR networks. For example, the described techniques can be applied to a variety of other wireless communication systems, such as Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and other systems and radio technologies not explicitly mentioned herein.

[0409] The information and signals described herein can be represented using any of a wide variety of different techniques and methods. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referred to throughout this description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or light particles, or any combination thereof.

[0410] The various illustrative boxes and components described herein can be implemented or executed using a general-purpose processor, DSP, ASIC, CPU, FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. The general-purpose processor may be a microprocessor, but in alternatives, the processor may be any processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors cooperating with a DSP core, or any other such configuration).

[0411] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions can be stored or transmitted as one or more instructions or code on a computer-readable medium. Other examples and implementations fall within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwired, or any combination thereof. Features implementing the functions can also be physically located in various locations, including being distributed such that different parts of the function are implemented at different physical locations.

[0412] Computer-readable media includes both non-transient computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transient storage media can be any available medium accessible to a general-purpose or special-purpose computer. 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.

[0413] 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".

[0414] 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.

[0415] This document, illustrated with reference to the accompanying drawings, describes exemplary configurations but does not represent all examples that can 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.

[0416] 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.
