[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 007,156, filed on April 8, 2020, entitled “QUALITY OF SERVICE OR PRIORITY CONFIGURATION FOR RELAY USER EQUIPMENT,” and U.S. Non-Provisional Patent Application No. 17 / 221,458, filed on April 2, 2021, entitled “QUALITY OF SERVICE OR PRIORITY CONFIGURATION FOR RELAY USER EQUIPMENT,” which are hereby expressly incorporated herein by reference.

[0003] Public domain

[0004] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for relaying quality of service (QoS) or priority configuration for a UE.

[0005] background

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless network may include several base stations (BSs) that can support communications for several user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, and an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receiving Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global level. NR (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR and other radio access technologies are still useful.

[0031] Detailed Description

[0032] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is independently implemented or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0033] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0034] It should be noted that while various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).

[0035] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, a B node, a gNB, a 5G B node (NB), an access point, a transmission reception point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0036] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0037] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0038] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.

[0039] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0040] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0042] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network) via, for example, a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0044] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0045] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) and / or may communicate using an operating band having a second frequency range (FR2), the first frequency range (FR1) may span 410 MHz to 7.125 GHz, and the second frequency range (FR2) may span 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz" and the like, if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave" and the like, if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0046] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described herein. Figure 1 Examples described.

[0047] Figure 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0048] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0049] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0050] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0051] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include coplanar sets of antenna elements and / or non-coplanar sets of antenna elements. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements coupled to one or more transmission and / or reception components (such as Figure 2 One or more antenna elements of one or more components).

[0052] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, where applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described with reference to Figure 3-8 described).

[0053] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as described with reference to Figure 3-8 described).

[0054] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the base station 110 may perform one or more techniques associated with quality of service (QoS) and / or priority configuration for relaying UEs, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 7 The process 700 Figure 8 800, and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include: a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example Figure 7 The process 700 Figure 8 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0055] In some aspects, UE 120 may include: means for receiving or determining configuration information for a side link between UE 120 and a remote UE, wherein the configuration information indicates one or more parameters associated with at least one of a priority level or a quality of service value associated with the side link; means for receiving or determining association information indicating that a logical channel on a radio access link is associated with a logical channel on the side link, wherein the association information is based at least in part on the one or more parameters for the side link; means for relaying traffic between the remote UE and the base station via the side link and the radio access link according to the association information; and so on. In some aspects, such means may include a method for combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0056] In some aspects, the base station 110 may include: means for transmitting radio access link information for a radio access link between the base station and a relay UE, wherein the radio access link information indicates one or more parameters for a logical channel on the radio access link, wherein the one or more parameters indicate at least one of a priority level associated with the radio access link or a quality of service value associated with the radio access link; means for communicating with a remote UE via the relay UE based at least in part on the radio access link information; means for transmitting configuration information for a side link between the remote UE and the relay UE, wherein the configuration information indicates one or more parameters for the side link, wherein the one or more parameters are associated with at least one of a priority level of the side link or a quality of service value associated with the side link; means for transmitting association information indicating that a logical channel on the radio access link is associated with a logical channel on the side link between the relay UE and the remote UE, wherein the association information is based at least in part on the one or more parameters for the logical channel on the radio access link; and so on. In some aspects, such means may include a combination of Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0057] although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functions described above with respect to these blocks may be implemented using a single hardware, software, or combined component or a combination of various components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0058] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described herein. Figure 2 Examples described.

[0059] In some frequency ranges, the radio access link between the UE and the base station may be impaired or blocked on a short time scale (such as a sub-second or millisecond time scale). One method of mitigating such impairment and / or blocking uses a relay UE. For example, a relay UE may provide a relay service between a remote UE and a base station. In some aspects, the remote UE may maintain a connection with the relay UE via a side link between the remote UE and the relay UE, and may maintain a connection with the base station via a radio access link between the remote UE and the base station. Thus, the resilience of the communication link between the remote UE and the network is improved, because communications that would travel via a blocked radio access link can instead be routed via a connection with the relay UE.

[0060] In some cases, a logical channel between a UE and a base station may be associated with one or more parameters, such as a quality of service (QoS) value, a priority level, etc. A logical channel (sometimes abbreviated as LCH) is a channel that carries information between the layers of a wireless communication device. For example, the medium access control (MAC) layer of a UE may use a logical channel to provide services to the radio link control (RLC) layer of the UE. A logical channel may be defined by the type of information carried by the logical channel. Typically, logical channels are distinguished into control channels (for transmitting control and configuration information) and traffic channels (for user data).

[0061] Traffic associated with the logical channel may need to satisfy constraints imposed by the one or more parameters, such as reliability, latency, throughput, and the like. However, if such traffic is communicated via a relay UE (e.g., from a base station to a relay UE via a radio access link, and then from the relay UE to a remote UE via a side link), the side link may not be configured to handle the constraints imposed by these parameters. For example, the side link may not be configured with a logical channel that satisfies the parameters, or a logical channel associated with the side link may have different parameters than a logical channel associated with the uplink. This may result in violation of QoS or priority requirements, reduced throughput, and reduced reliability and / or increased latency.

[0062] The techniques and apparatus described herein provide for the configuration of mappings between logical channels on a radio access link and logical channels on a side link. For example, the mapping may provide for logical channels associated with compatible parameters (e.g., QoS values, priority levels, etc.) to be mapped to each other between the side link and the radio access link so that the requirements associated with these parameters are met for relay traffic. This mapping may be configured by a base station (in the case where the base station configures the radio access link and the side link) and / or a relay UE (in the case where the relay UE configures the side link). In this way, consistency with QoS and / or priority requirements of network traffic is improved, thereby enabling the use of relay UEs in conjunction with such network traffic. As a result, network coverage is improved and the performance of remote UEs is improved, particularly in higher frequency ranges that may be subject to frequent interruptions of the radio access link.

[0063] Figure 3 is a diagram illustrating an example 300 of a sidelink communication configuration for a remote UE and a relay UE according to the present disclosure. Figure 3 The present invention includes a BS 110, a remote UE 120, and a relay UE 120. The remote UE 120 may have a radio access link 310 with the BS 110. For example, the radio access link 310 may be a Uu link, etc. As further shown, the remote UE 120 may have a side link 320 with the relay UE 120. For example, the side link may be a ProSe (PC5) link, a Bluetooth link, a WiFi link, or another form of wireless link. As further shown, the relay UE 120 may have a radio access link 330 with the BS 110. For example, the radio access link 330 may be a Uu link, etc. A dual connectivity configuration (i.e., a configuration with a radio access link 310 and a side link 320) may provide increased robustness and reliability for communications between the remote UE 120 and the BS 110, because such communications may be provided via the radio access link 310 and / or the radio access link 330 (via the side link 320). This may also provide faster link selection and / or aggregation because control information may be provided by the BS 110 to the remote UE 120. For example, the BS 110 may schedule the radio access link 310 and the side link 320 (e.g., one at a time or simultaneously). In some aspects, the relay UE 120 and / or the remote UE 120 may be associated with two or more protocol stacks (partial or full), such as in conjunction with Figure 4 Techniques and apparatus described herein provide mapping of logical channels on the side link 320 to logical channels on the radio access link 330 such that QoS values, priority levels, etc. are maintained on the side link 320 and the radio access link 330.

[0064] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described herein. Figure 3 Examples described.

[0065] Figure 4 is a diagram illustrating an example 400 of a protocol stack architecture for a relay UE according to the present disclosure. The protocol stack architecture is illustrated for a remote UE 120, a relay UE 120, and a BS 110. A radio access link 310 (illustrated, for example, as a Uu interface) is illustrated by a dotted line between the protocol stack of the remote UE 120 and the protocol stack of the BS 110. A side link 320 (illustrated, for example, as a PC5 interface) is illustrated by a dotted line between the side link protocol stack of the remote UE 120 and the side link protocol stack of the relay UE 120. A radio access link 330 (illustrated, for example, as a Uu interface) is illustrated by a dotted line between the NR protocol stack of the relay UE 120 and the NR protocol stack of the BS 110. Compared to layer 3 relaying performed in the radio resource control layer, Figure 4 The protocol stack architecture shown in can be used for layer 2 relaying, where traffic is relayed in the physical layer or the media access control layer. Layer 2 relaying can provide reduced latency and improved throughput relative to higher layer relaying (such as layer 3 relaying).

[0066] As shown, the remote UE 120 and the BS 110 may be associated with corresponding non-access stratum (NAS) entities, NR radio resource control (RRC) entities, and NR packet data convergence protocol (PDCP) entities. These entities may communicate with each other via one or both of the radio access link 310 or the relay UE 120 (i.e., via the radio access link 330 and the side link 320). When communication occurs via the radio access link 310, the remote UE 120 may use NR-RLC, medium access control (MAC), and physical (PHY) entities to communicate with the corresponding NR-RLC, NR-MAC, and NR-PHY entities of the BS 110.

[0067] When communication occurs via the relay UE 120, the remote UE 120 and the relay UE 120 may communicate via the side link 320. For example, the remote UE 120 and the relay UE 120 may be associated with respective adaptation entities 410 and 420. The adaptation entities 410 and 420 may handle processing and preparation of data for transmission via the side link 320 and the radio access link 330. For example, the adaptation entities 410 / 420 may handle relaying between the side link 320 and the radio access link 330, such as based at least in part on a mapping between a logical channel on the side link 320 and a logical channel on the radio access link 330 determined using the techniques described herein. In addition, the remote UE 120 and the relay UE 120 may maintain respective side link stacks 430 and 440. Thus, the remote UE 120 and the relay UE 120 may be referred to as maintaining multiple protocol stacks concurrently or simultaneously, including a radio access (e.g., NR) protocol stack and a side link (e.g., PC5) protocol stack.

[0068] In some aspects, the BS 110 may configure the sidelink 320. In some aspects, the relay UE 120 (e.g., the sidelink protocol stack 440 of the relay UE 120) may configure the sidelink 320. The techniques and apparatus described herein provide for mapping of logical channels on the radio access link 330 to logical channels on the sidelink 320 (according to QoS or priority parameters of those logical channels), regardless of whether the BS 110 or the relay UE 120 configures the sidelink 320.

[0069] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.

[0070] Figure 5 1 is a diagram illustrating an example 500 of configuring a mapping between a logical channel on a side link and a logical channel on a radio access link according to the present disclosure. In example 500, a relay UE 120 configures a side link (e.g., Figure 3 and 4 Thus, the relay UE 120 determines a mapping of a logical channel on the side link to a logical channel on a radio access link (eg, radio access link 330) between the relay UE 120 and the BS 110.

[0071] As indicated by reference numeral 510, BS 110 may provide radio access link information to relay UE 120. The radio access link information may identify one or more parameters for a radio access link between relay UE 120 and BS 110. For example, the radio access link information may identify one or more logical channels of the radio access link, and may identify one or more parameters (e.g., QoS value, priority level, traffic type, QoS flow identifier) ​​for the one or more logical channels. In some aspects, BS 110 may provide the radio access link information as part of a configuration of the radio access link, as part of a configuration of a layer 2 relay service at relay UE 120, and so on. In some aspects, BS 110 may provide the information to an NR protocol stack of relay UE 120.

[0072] In some aspects, the radio access link information may identify a mapping rule. The mapping rule may indicate parameters (e.g., QoS values, priority levels, etc.) for the logical channels of the radio access link and one or more rules for mapping these logical channels to corresponding logical channels on the side link. For example, the mapping rule may indicate a mapping between parameters for logical channels on the radio access link and parameters for logical channels on the side link. For example, the mapping rule may indicate that the parameters will be equal on the side link and the radio access link. As another example, the mapping rule may indicate that the parameters on the side link will be equal to or more stringent than the parameters on the radio access link. In some aspects, the relay UE 120 may perform the operations described herein without receiving the radio access link information from the BS 110. In some aspects, the mapping rule may be universal, such as specified in a wireless communication standard. In some aspects, the mapping rule may be configured. For example, a mapping rule may be configured for a logical channel pair (e.g., a pairing of a side link logical channel and a radio access link logical channel).

[0073] In some aspects, BS 110 may configure the mapping rules. In some aspects, BS 110 may update the mapping rules via dynamic signaling (such as L1 / L2 signaling). For example, BS 110 may configure multiple mapping rules and may use MAC signaling, downlink control information (DCI), etc. to indicate the selected mapping rule.

[0074] As indicated by reference numeral 520, the relay UE 120 may configure a side link between the relay UE 120 and the remote UE 120. For example, the relay UE 120 may establish a connection with the remote UE 120, may configure one or more logical channels on the connection, etc. In some aspects, a side link protocol stack (e.g., a PC5 protocol stack, etc.) of the relay UE 120 may configure the side link.

[0075] In some aspects, the relay UE 120 may configure the side link based at least in part on the radio access link information. For example, the relay UE 120 may configure one or more logical channels (e.g., the priority level of the side link logical channel may be at least as high as the priority level of the radio access link logical channel, or the QoS value of the side link logical channel may be at least as high as the QoS value of the radio access link logical channel) according to the above-mentioned mapping rules. In this case, the NR protocol stack of the relay UE 120 may communicate the radio access link information to the side link protocol stack of the relay UE 120, and the side link protocol stack of the relay UE 120 may configure the side link based at least in part on the radio access link information. As a result, the NR RRC entity and the side link RRC entity of the relay UE 120 may coordinate their logical channel configurations. For example, the side link RRC entity may apply the logical channel configuration on the side link based at least in part on information related to the corresponding logical channel configuration on the radio access link received from the NR RRC entity and based at least in part on the above-mentioned mapping rules.

[0076] As indicated by reference numeral 530, the relay UE 120 may determine association information. The association information may identify an association of one or more logical channels on a radio access link with one or more logical channels on a side link. For example, the association information may indicate that a radio access link logical channel is associated with (e.g., mapped to) a side link logical channel, which means that the traffic associated with the radio access link logical channel is transmitted (e.g., relayed) via the side link on the side link logical channel, and the traffic associated with the side link logical channel is transmitted (e.g., relayed) via the radio access link on the radio access link logical channel. In some aspects, the association information may be defined as a table (e.g., a mapping table) or some other form of correspondence between the radio access link logical channel and the side link logical channel. In some aspects, the association information may be configured for the relay UE 120, as described elsewhere herein. For example, the association information may be configured via RRC, such as a portion of the radio access link information, a side link configuration, and the like.

[0077] In some aspects, the relay UE 120 may determine the association information based at least in part on one or more of the radio access link information and the configuration of the side link. For example, the relay UE 120 may map the logical channels to each other based at least in part on the parameters associated with the logical channels. More specifically, the relay UE 120 may map the radio access link logical channel with a given QoS value or a given priority level to a side link logical channel with an appropriate QoS value or an appropriate priority level (e.g., an equivalent QoS value and / or priority level, a more stringent QoS value and / or priority level, etc.). Thus, the relay UE 120 may configure the corresponding logical channels of the Uu link and the side link to match or have a corresponding relationship in terms of priority and QoS attributes.

[0078] In some aspects, the association information may indicate one or more one-to-one mappings. The one-to-one mapping is between a radio access link logical channel and a side link logical channel. The one-to-one mapping may simplify the relay operation. For example, the adaptation layer of the relay UE 120 may be able to perform relaying for the one-to-one mapping without an explicit header identifying the target UE (i.e., the remote UE 120). In this case, the adaptation layer may perform relaying based at least in part on the logical channel identifier of the remote UE (which may be a unique logical channel identifier).

[0079] As indicated by reference numeral 540, the relay UE 120 (e.g., the sidelink RRC entity of the relay UE 120) may provide a sidelink configuration to the remote UE 120. The sidelink configuration may configure the remote UE 120 for relay communication with the relay UE 120 and the BS 110. For example, the sidelink configuration may identify the configuration and corresponding parameters of the sidelink logical channel. In some aspects, the sidelink configuration information may include at least a portion of the association information or may be determined based at least in part on the association information. In some aspects, the provision of the sidelink configuration shown by reference numeral 540 may be considered as part of the configuration of the sidelink shown by reference numeral 530. In some aspects, the determination of the association information shown by reference numeral 530 may be considered as part of the configuration of the sidelink described by reference numeral 520.

[0080] As indicated by reference numeral 550, the remote UE 120 and the BS 110 may communicate via a side link and a radio access link (e.g., via the relay UE 120). For example, the remote UE 120 may communicate with the relay UE 120 via the side link according to the side link configuration, and the relay UE 120 may relay such communication to the BS 110 via the radio access link according to the association information. As another example, the BS 110 may transmit the communication to the relay UE 120 on the radio access link logical channel. The relay UE 120 may receive the communication on the radio access link logical channel and identify the corresponding side link logical channel for the communication based at least in part on the configuration information or the association information indicated by reference numeral 540. Thus, the relay UE 120 may configure the side link between the relay UE 120 and the remote UE 120, and may map the logical channels on the radio access link to the logical channels on the side link so that the QoS value and / or priority level of the radio access link is met on the side link.

[0081] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described herein. Figure 5 Examples described.

[0082] Figure 6 600 is a diagram illustrating another example of configuration of mapping between logical channels on a side link and logical channels on a radio access link according to the present disclosure. In example 600, a BS 110 configures a radio access link between the BS 110 and a relay UE 120 and a side link between the relay UE 120 and a remote UE 120.

[0083] As indicated by reference numeral 610, BS 110 may provide radio access link information to relay UE 120. In some aspects, BS 110 may provide the information as part of setting up or configuring a radio access link between BS 110 and relay UE 120. For example, the radio access link information may include RRC information related to establishing or configuring a radio access link. In some aspects, the radio access link information may include information about Figure 5 At least a portion of the radio access link information described.

[0084] As indicated by reference numeral 620, BS 110 may configure a side link between remote UE 120 and relay UE 120. For example, BS 110 may configure the side link based at least in part on one or more parameters associated with the radio access link (e.g., one or more QoS values, one or more priority levels, etc.). In some aspects, BS 110 may configure one or more logical channels on the side link based at least in part on one or more logical channels on the radio access link. For example, BS 110 may configure one or more logical channels on the side link using parameters that match or exceed the parameters of one or more logical channels on the radio access link (e.g., QoS values, priority levels, etc.). In some aspects, BS 110 may configure one or more logical channels on the side link based at least in part on a mapping rule (e.g., a mapping rule described above in conjunction with the QoS value). Figure 5 Thus, BS 110 configures a set of logical channels on the side link that can meet the QoS requirements and priority requirements of the radio access link.

[0085] In some aspects, as mentioned above, BS 110 may instruct a sidelink RRC entity (e.g., a PC5-RRC entity of a remote UE 120 or a relay UE 120) how to configure a sidelink logical channel (such as via RRC signaling, etc.). For example, BS 110 may provide a configuration of a sidelink logical channel. Additionally or alternatively, BS 110 may configure the sidelink RRC entity with multiple configurations of the sidelink logical channel, and the sidelink RRC entity may select one of the multiple configurations of the sidelink logical channel, which increases the flexibility of the configuration of the sidelink logical channel.

[0086] In some aspects, BS 110 and UE 120 (such as remote UE 120 or relay UE 120) may negotiate parameters for the sidelink logical channel. For example, UE 120 may transmit information indicating requested parameters or supported parameters to BS 110. BS 110 may configure the sidelink logical channel according to the parameters or may provide a response indicating different parameters. In this case, in some aspects, BS 110 may update the configuration of the sidelink logical channel based at least in part on the results of the negotiation.

[0087] In some aspects, BS 110 may configure multiple parameter sets (i.e., QoS values, priority levels, etc.) and may select between the multiple parameter sets. For example, BS 110 may transmit information indicating the selected parameter set via MAC signaling, DCI, etc. (e.g., L1 / L2 signaling). In some aspects, BS 110 may select between the multiple parameter sets based at least in part on conditions such as link delays, error rates, mobility states, etc. experienced by remote UE 120 or relay UE 120.

[0088] As indicated by reference numeral 630, BS 110 may determine association information for relay UE 120. The association information may indicate an association (e.g., mapping) between one or more logical channels on the radio access link and one or more logical channels on the sidelink. For example, the association information may map the radio access link logical channel to the sidelink logical channel based at least in part on the radio access link logical channel and the sidelink logical channel being associated with one or more identical parameter values, or based at least in part on the radio access link logical channel and the sidelink logical channel being associated with parameter values ​​that satisfy a mapping rule. The mapping rule may be combined with Figure 5 Give a description.

[0089] As indicated by reference numeral 640, BS 110 may provide configuration information to relay UE 120 (e.g., using RRC signaling, etc.). The configuration information may indicate configuration and / or associated information of the sidelink. As further shown, in some aspects, relay UE 120 may provide configuration information (e.g., at least a portion of the configuration information) to relay UE 120. For example, relay UE 120 may relay the configuration information without modifying the configuration information. As another example, relay UE 120 may generate configuration information for remote UE 120 based at least in part on the configuration information received from BS 110. In some aspects, BS 110 may directly (e.g., via Figure 3 The radio access link 310 shown in FIG. 1 provides configuration information (eg, at least a portion of the configuration information) to the UE 120.

[0090] As indicated by reference numeral 650, the BS 110 and the remote UE 120 may communicate via the relay UE 120 (e.g., using a side link and a radio access link) according to the associated information. For example, the BS 110 may transmit a communication to the relay UE 120 on a radio access link logical channel. The relay UE 120 may receive the communication on the radio access link logical channel and identify a corresponding side link logical channel for the communication based at least in part on the configuration information or the associated information indicated by reference numeral 640. As another example, the remote UE 120 may communicate with the relay UE 120 via the side link according to the side link configuration, and the relay UE 120 may relay such communication to the BS 110 via the radio access link according to the associated information. Thus, the BS 110 may configure the side link between the relay UE 120 and the remote UE 120, and may map the logical channels on the radio access link to the logical channels on the side link so that the QoS value and / or priority level of the radio access link is met on the side link.

[0091] As indicated above, Figure 6are provided as examples. Other examples may differ from those described herein. Figure 6 Examples described.

[0092] Figure 7 700 is a diagram illustrating an example process 700 performed, for example, by a UE according to the present disclosure. The example process 700 is a diagram in which a relay UE (e.g., Figure 3-6 An example of a UE 120, a relay UE 120, etc.) performing operations associated with QoS or priority configuration for a relay UE.

[0093] like Figure 7 As shown in , in some aspects, process 700 may include: receiving or determining configuration information for a side link between a relay UE and a remote UE, wherein the configuration information indicates one or more parameters associated with at least one of a priority level or a quality of service value associated with the side link (box 710). For example, a relay UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receiving processor 258, controller / processor 280, etc.) may receive configuration information for a side link between a relay UE and a remote UE, as described above. As another example, a relay UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receiving processor 258, controller / processor 280, etc.) may determine configuration information for a side link between a relay UE and a remote UE, as described above. In some aspects, the configuration information indicates one or more parameters associated with at least one of a priority level or a quality of service value associated with the side link.

[0094] like Figure 7 As further shown in , in some aspects, process 700 may include: receiving or determining association information indicating that a logical channel on the radio access link is associated with a logical channel on the side link, wherein the association information is based at least in part on the one or more parameters for the side link (block 720). For example, a relay UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive or determine association information indicating that a logical channel on the radio access link is associated with a logical channel on the side link, as described above. As another example, a relay UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may determine association information indicating that a logical channel on the radio access link is associated with a logical channel on the side link, as described above.
