Description
RESOURCE ALLOCATION FOR AIOT DEVICETECHNICAL FIELD
[0001] The present disclosure relates to wireless communications, and more specifically to devices and methods for supporting resource allocation for an ambient internet of things (ambient-IoT or AIoT) device.BACKGROUND
[0002] A wireless communications system may include one or multiple network communication devices, such as base stations, which may be otherwise known as an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. Each network communication devices, such as a base station may support wireless communications for one or multiple user communication devices, which may be otherwise known as UE, or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) . Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G) ) .
[0003] In recent years, internet of things (IoT) has attracted much attention in the wireless communication world. More “things” are expected to be interconnected for improving productivity efficiency and increasing comforts of life. Further reduction of size, complexity, and power consumption of IoT devices can enable the deployment of tens or even hundreds of billion IoT devices for various applications and provide added value across the entire value chain. Considering the limited size and complexity required by practical applications for AIoT devices, the output power of energy harvester is typically from 1μW to a few hundreds of μW. Existing cellular devices may not work well with energy harvesting due to their peak power consumption of higher than 10mW.
[0004] Through Release 18 and Release 19, a set of study items (SIs) and work items (WIs) were completed across work groups (WGs) of the third generation partnership project (3GPP) , leading to the specification of Device 1 (having ~1 μW power consumption, and with device-to-reader (D2R) transmission by backscattering) for use in Deployment Scenario 1 with Topology 1, i.e., by direct connection between a base station reader and the AIoT device. The traffic types supported are device originated by device terminated trigger (DO-DTT) and device terminated (DT) , with a focus on supporting use cases for indoor inventory and indoor command applications.
[0005] To support the more use cases spanning indoor and outdoor applications, for example, sensor, positioning applications, Release 20 AIoT aims to work on objectives for active devices and outdoor scenario. One of objective is to support the necessary support for one or more active devices, including all traffic types DO-DTT, DT, device-originated autonomously (DO-A) , taking the Release 19 specification as the starting point.
[0006] From one perspective, at least the following aspect of the air interface for DO-DTT and DT traffic types is not sufficient for the DO-A traffic type: for DO-DTT and DT traffic types, one or more D2R resources for D2R transmission are indicated in a reader-to-device (R2D) transmission, but this is not applicable at least for the first D2R transmission for DO-A traffic.
[0007] From another perspective, the DO-A traffic type / use case cannot be supported with the current design in the study item. It is assessed that at least the AIoT paging is an aspect / part of the current design which is not sufficient for the DO-A use case.
[0008] Thus, there is a need to solve the issue related to resource configuration for device with DO-A data in AIoT system.SUMMARY

[0071] As described above, there is a need to solve the issue related to resource configuration for device with DO-A data in AIoT system.
[0072] In view of the above, the present disclosure provides a solution that supports resource allocation for an AIoT device. In this solution, a first device receives a first R2D message comprising first resource configuration information from a second device. The first resource configuration information comprises at least one resource dedicated for at least one device to perform at least one DO-A data transmission. The at least one device comprises the first device.

This solution enables allocation of dedicated resources per device for the DO-A data transmission in an AIoT system.
[0073] Aspects of the present disclosure are described in the context of a wireless communications system.
[0074] Fig. 1 illustrates an example of a wireless communications system 100 that supports resource allocation for an AIoT device in accordance with aspects of the present disclosure. The wireless communications system 100 may include one at least one of network entities 102 (also referred to as network equipment (NE) ) , one or more terminal devices or UEs 104, a core network (CN) 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including institute of electrical and electronics engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0075] The network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station (BS) , a network element, a radio access network (RAN) node, a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface. The network entities 102 may be collectively referred to as network entities 102 or individually referred to as a network entity 102. Hereinafter, some implementations of the present disclosure will be described by taking a base station as an example of the network entity 102. Thus, the network entity 102 may be used interchangeably with the base station 102.
[0076] A network entity 102 may provide a geographic coverage area 112 for which the network entity 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc. ) for one or more UEs 104 within the geographic coverage area 112. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas 112 may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0077] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an internet-of-things (IoT) device, an internet-of-everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.
[0078] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in Fig. 1. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in Fig. 1. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.
[0079] A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0080] A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .
[0081] In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, such as an integrated access backhaul (IAB) network, an open radio access network (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN intelligent controller (RIC) (e.g., a near-real time RIC (Near-RT RIC) , a non-real time RIC (Non-RT RIC) ) , a service management and orchestration (SMO) system, or any combination thereof.
[0082] An RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0083] Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., a layer 3 (L3) , a layer 2 (L2) ) functionality and signaling (e.g., radio resource control (RRC) , service data adaption protocol (SDAP) , packet data convergence protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a layer 1 (L1) (e.g., physical (PHY) layer) or an L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU.
[0084] Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .
[0085] A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-c, F1-u) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.
[0086] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a packet data network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0087] The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .
[0088] In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0089] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0090] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0091] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0092] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0093] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.
[0094] Fig. 2 illustrates another example of a wireless communications system 200 that supports resource allocation for an AIoT device in accordance with aspects of the present disclosure. As shown in Fig. 2, the wireless communications system 200 may comprise a first device 210, a second device 220 and a third device 230 in the core network 106.
[0095] In some implementations, the first device 210 may be implemented as an AIoT device. For example, the first device 210 may be implemented as a tag. In such implementations, the second device 220 may be implemented as a reader for the AIoT device.
[0096] In some implementations, the second device 220 may be implemented as the base station 102 in Fig. 1. In such implementations, the first device 210 may directly and bidirectionally communicate with the second device 220. The communication between the second device 220 and the first device 210 may comprise at least one of the following: Ambient IoT data or Ambient IoT signalling.
[0097] Alternatively, in some implementations, the second device 220 may be implemented as an intermediate node between the first device 210 and the base station 102. In such implementations, the first device 210 may communicate bidirectionally with the second device 220. In such implementations, the second device 220 may be referred to as an intermediate node. For example, the intermediate node may be a relay, IAB node, the UE 104 in Fig. 1, or repeater which is capable of AIoT. The intermediate node transfers AIoT data and / or signalling between the first device 210 and the base station 102.
[0098] In some implementations, the third device 230 may be an entity in the core network 106 which communicates with at least one of the first device 210 and the second device 220. The third device 230 may be a network function (NF) in the core network 106. For example, the third device 230 may be implemented as an AIoT function (AIoTF) or an access and mobility management function (AMF) of a 5GC.
[0099] It is to be understood that the numbers of devices shown in Fig. 2 are only for the purpose of illustration. The wireless communications system 200 may include any suitable number of devices.
[0100] Fig. 3 illustrates a signaling diagram illustrating an example process 300 that supports resource allocation for an AIoT device in accordance with aspects of the present disclosure. The process 300 may involve the first device 210, the second device 220 and the third device 230 in Fig. 2. For the purpose of discussion, the process 300 will be described with reference to Fig. 2.
[0101] As shown in Fig. 3, the third device 230 transmits 310 CN assistance information to the second device 220.
[0102] In some implementations, the CN assistance information may comprise information related to at least one ID of the at least one device with at least one DO-A traffic. The at least one device may comprise the first device 210.
[0103] In some implementations, the information related to the at least one ID of the at least one device may comprise at least one permanent device ID or paging ID of the at least one device.
[0104] Alternatively, in some implementations, the information related to the at least one ID of the at least one device may comprise at least one partial ID of the at least one device. Each of the at least one partial ID is a truncated unique part from a respective one of the at least one permanent device ID based on a predetermined algorithm.
[0105] Alternatively, in some implementations, the information related to the at least one ID of the at least one device may comprise at least one temporary ID of the at least one device. The at least one temporary ID is allocated during a registration procedure of the at least one device.
[0106] Alternatively, in some implementations, the information related to the at least one ID of the at least one device may comprise a range of IDs comprising the at least one ID of the at least one device. For example, the range of IDs may be 0001-0008.
[0107] Alternatively, in some implementations, the information related to the at least one ID of the at least one device may comprise an ID of a group comprising the at least one device. Each of the at least one device may be allocated a dedicated group ID during the device registration procedure.
[0108] Alternatively or additionally, in some implementations, the CN assistance information may comprise a first number of the at least one device with the at least one DO-A traffic.
[0109] In some implementations, the first number of the at least one device with the at least one DO-A traffic may be the total number of the at least one device with multiple DO-A traffics.
[0110] Alternatively, in some implementations, the first number of the at least one device with the at least one DO-A traffic may be the total number of the at least one device with one DO-A traffic.
[0111] Alternatively, in some implementations, the first number of the at least one device with the at least one DO-A traffic may be the total number of the at least one device within an active device group with the at least one DO-A traffic.
[0112] Alternatively, in some implementations, the CN assistance information may comprise the numbers of the at least one device with each of the multiple DO-A traffics. For example, the CN assistance information may comprise the first number of at least one device with a first DO-A traffic, a second number of at least one device with a second DO-A traffic and so on.
[0113] Alternatively or additionally, in some implementations, the CN assistance information may comprise information related to the at least one DO-A traffic.
[0114] In some implementations, the information related to the at least one DO-A traffic may comprise at least one of the following: · a service ID associated with each of the at least one DO-A traffic, · a service type associated with each of the at least one DO-A traffic, · a pattern of each of the at least one DO-A traffic, · expected arriving time of the at least one DO-A traffic, or · a service priority associated with each of the at least one DO-A traffic.
[0115] In some implementations, the service type associated with each of the at least one DO-A traffic may comprise one of the following: sensing service, positioning service, or emergency service.
[0116] In some implementations, the pattern of each of the at least one DO-A traffic may comprise one of the following: periodic and one-shot.
[0117] In some implementations, the information related to the at least one DO-A traffic may be different for different devices. In such implementations, the information related to the at least one DO-A traffic may be associated with a respective one of the devices. For example, the information related to the at least one DO-A traffic may comprise first information related to a first DO-A traffic associated with an AIoT device #1 and second information related to a second DO-A traffic associated with an AIoT device #2.
[0118] Alternatively or additionally, in some implementations, the CN assistance information may comprise a first size of DO-A data for one of the at least one DO-A traffic.
[0119] Alternatively or additionally, in some implementations, the CN assistance information may comprise a second size of DO-A data for one or more DO-A traffics from each of the at least one device.
[0120] Alternatively or additionally, in some implementations, the CN assistance information may comprise a third size of DO-A data for each of the at least one DO-A traffic from each of the at least one device.
[0121] With continued reference to Fig. 3, the second device 220 transmits 320, based on the CN assistance information, a first R2D message to the at least one device. The at least one device may comprise the first device 210.
[0122] The first R2D message comprises first resource configuration information. The first resource configuration information may comprise at least one resource dedicated for the at least one device to perform at least one DO-A data transmission. Hereinafter, the at least one resource dedicated for the at least one device is also referred to as at least one dedicated resource for brevity.
[0123] In some implementations, the first resource configuration information may comprise the information related to the at least one device and information related to at least one dedicated resource.
[0124] In some implementations, the information related to the at least one device may comprise one of the following: · at least one permanent device ID or paging ID of the at least one device; · at least one partial ID of the at least one device, wherein each of the at least one partial ID is a truncated unique part from a respective one of the at least one permanent device ID based on a predetermined algorithm; · at least one temporary ID of the at least one device, wherein the at least one temporary ID is allocated during a registration procedure of the at least one device; · a range of IDs comprising the at least one ID of the at least one device; or · an ID of a group comprising the at least one device.
[0125] Some implementations of the information related to the at least one device have been described with respect to the action 310. Details of these implementations are omitted for brevity.
[0126] In some implementations, the information related to the at least one dedicated resource may comprise information related to at least one time / frequency resource.
[0127] In some implementations, the information related to the at least one dedicated resource may further comprise at least one ID of the at least one resource.
[0128] In some implementations, the at least one resource is configured with a fixed or default size.
[0129] In some implementations, the first resource configuration information may indicate association between the at least one dedicated resource and the information related to the at least one device.
[0130] In some implementations, if the information related to the at least one device comprises at least one permanent device ID or paging ID of the at least one device, the second device 220 allocates at least one dedicated resource for each permanent device ID or paging ID. Thus, the first resource configuration information may indicate association between the at least one dedicated resource and each permanent device ID or paging ID.
[0131] Alternatively, in some implementations, if the information related to the at least one device comprises at least one partial ID of the at least one device, the second device 220 allocates at least one dedicated resource for each partial ID. Thus, the first resource configuration information may indicate association between the at least one dedicated resource and each partial ID.
[0132] Alternatively, in some implementations, if the information related to the at least one device comprises at least one temporary ID of the at least one device, the second device 220 allocates at least one dedicated resource for each temporary ID. Thus, the first resource configuration information may indicate association between the at least one dedicated resource and each temporary ID.
[0133] Alternatively, in some implementations, if the information related to the at least one device comprises a range of IDs comprising the at least one ID of the at least one device, the second device 220 allocates a group or set of resources for the at least one device, the at least one ID of which is in the range of IDs. Thus, the first resource configuration information may indicate association between the resources in the group of resources and IDs in the range of IDs.
[0134] For example, the range of IDs may be 0001-0008 and the group of resources may comprise eighth resource blocks. The eighth resource blocks may comprise resource blocks #1, #2, …, #8. Table 1 shows an example of the association between the resources in the group of resources and IDs in the range of IDs. Table 1
[0135] In the example of Table 1, the first resource configuration information may indicate that the resource block #1 is allocated to a device #0001, the resource block #2 is allocated to a device #0002, …, the resource block #8 is allocated to a device #0008.
[0136] Alternatively, in some implementations, the association between the resources in the group of resources and IDs in the range of IDs may be predefined. In such implementations, the first resource configuration information may indicate that the association between the resources in the group of resources and the range of IDs as shown in Table 2. Table 2
[0137] Alternatively, in some implementations, if the information related to the at least one device comprises an ID of a group comprising the at least one device, the second device 220 allocates a group or set of resources for the at least one device in the group. Thus, the first resource configuration information may indicate association between the resources in the group of resources and an ID of the group.
[0138] Returning to Fig. 3, upon receiving the first R2D message, the first device 210 performs a first DO-A data transmission on a first resource dedicated for the first device 210 among the at least one resource. Hereinafter, the first resource dedicated for the first device 210 is also referred to as a first dedicated resource for brevity.
[0139] In some implementations, the first R2D message may be an R2D message newly defined for Release 20 AIoT devices and the first R2D message cannot be decoded by legacy Release 19 AIoT devices. In some implementations, a new message type is introduced for the first R2D message.
[0140] Alternatively, the first R2D message may be a legacy R2D message defined in Release 19, e.g., paging message and so on, which can be decoded by both Release 19 AIoT devices and Release 20 AIoT devices.
[0141] In some implementations, the first device 210 may perform 340 the first DO-A data transmission to the second device 220, and the second device 220 may forward 350 the first DO-A data transmission to the third device 230.
[0142] In some implementations, the first device 210 may monitor and receive the first R2D message comprising the first resource configuration information. For example, the first device 210 may monitor and receive the first R2D message when the first device 210 is powered on. Then, the first device 210 may decode the first resource configuration information and determine whether the information related to the at least one device (such as ID of the at least one device) is mapped to itself. If the information related to the at least one device (such as ID of the at least one device) is mapped to itself, the first device 210 uses the associated time / frequency resource to perform DO-A data transmission. If the information related to the at least one device (such as ID of the at least one device) is not mapped to itself, the first device 210 ignores or discards the received R2D message.
[0143] In some implementations, if the first device 210 receives the first R2D message successfully, the first device 210 may transmit 330 a positive acknowledge (ACK) to the second device 220. The resource for ACK transmission is reserved / indicated by the second device 220 in the first R2D message. The resource for ACK transmission is associated with the first resource configuration information.
[0144] In some implementations, if the first device 210 may fail to receive the first R2D message due to e.g. power-off or in sleep state. In this case, the first device 210 can only rely on retransmission of the first resource configuration information from the second device 220, or left to implementation of the CN 106 to acquire the resource configuration for DO-A data transmission when it changes into power-on state.
[0145] In some implementations, to ensure the first resource configuration information can be received by the at least one device as much as possible, the second device 220 may transmit, to one or more of the at least one device, a second R2D message comprising at least part of the first resource configuration information.
[0146] In some implementations, based on implementation of the second device 220, the second device 220 may transmit, to one or more of the at least one device, the second R2D message comprising at least part of the first resource configuration information.
[0147] In some implementations, based on implementation of the CN 106, the second device 220 may transmit, to one or more of the at least one device, the second R2D message comprising at least part of the first resource configuration information. For example, the third device 230 in the CN 106 may indicate the second device 220 to transmit the second R2D message if expected DO-A data is not received by the third device 230.
[0148] In some implementations, the second device 220 may transmit the second R2D message by performing blind retransmission of the first R2D message with a configured / specified interval.
[0149] In some implementations, based on feedback from the at least one device, the second device 220 may transmit, to one or more of the at least one device, the second R2D message comprising at least part of the first resource configuration information.
[0150] In some implementations, the first device 210 may transmit ACK to the second device 220 if the first R2D message is received successfully.
[0151] Then, the second device 220 may perform retransmission of the first R2D message when the second device 220 does not receive the ACK from other device than the first device 210 on the allocated resource within a timer, or until the next R2D message (such as the second R2D message) is triggered from the second device 220, or when the second device 220 does not receive D2R transmission from other device on the allocated resource targeted for the other device.
[0152] In such implementations, the second device 220 may only retransmit part of the first resource configuration information associated with only for part of the at least one device which failed to receive the first resource configuration information, or just perform repetition of the first R2D message including the first resource configuration information.
[0153] In such implementations, if the second device 220 performs repetition of the first R2D message including the first resource configuration information and the first device 210 received the first R2D message successfully, the first device 210 will skip or ignore the repetition of the first R2D message by checking whether the included time / frequency resource targeted to itself is the same or not.
[0154] In some implementations, to guarantee the resource efficiency, the first resource dedicated for the first device 210 (i.e., the first dedicated resource) can be released from both the first device 210 and the second device 220 when at least one condition is satisfied.
[0155] In some implementations, each of the at least one dedicated resource is configured with a valid timer or a valid duration. For example, the first dedicated resource is configured with a first valid timer. When the first device 210 receives the first dedicated resource with a first valid timer, the first device 210 starts the first valid timer. When the second device 220 transmits the first dedicated resource with the first valid timer, the second device 220 starts the first valid timer. If the first valid timer expires, both the first device 210 and the second device 220 may release the first dedicated resource.
[0156] In some implementations, the first device 210 may transmit, to the second device 220, a first indication indicating the second device 220 to release the first dedicated resource. For example, if the first device 210 has completed the first DO-A data transmission, the first device 210 may transmit the first indication to the second device 220. The second device 220 may release the first dedicated resource based on the first indication. More specifically, the first indication may comprise 1 bit to indicate the second device to release the first dedicated resource or further comprise the indication to indicate the second device to release part of first dedicated resource. When the first device 210 transmits the first indication, the first device 210 may release the first dedicated resource or part of first dedicated resource; After the second device 220 received the first indication from the first device 210, the second device 220 may release the first dedicated resource or part of dedicated resource.
[0157] For example, if the first dedicated resource is periodic, both the first device 210 and the second device 220 may release the resource for several cycles due to short unavailability of the first device 210 or DO-A data.
[0158] In some implementations, when there is not available DOA data, all DOA data has been transmitted over, or the first device 210 does not have energy in a short future, the first device 210 may transmit the first indication to the second device 220. The second device 220 may release the first dedicated resource based on the first indication.
[0159] In some implementations, the first device 210 may transmit, to the second device 220, a second indication indicating an end of the first DO-A data transmission (for each resource if it is configured periodically) . Specifically, for the first dedicated resource which is configured periodically, the second indication may indicate an end of the first DO-A data transmission for the resource of each configured cycle.
[0160] In some implementations, when the first device 210 transmits the second indication, the first device 210 may release the first dedicated resource. After the second device 220 received the second indication from the first device 210, the second device 220 may release the first dedicated resource based on the second indication.
[0161] In some implementations, after DO-A traffic is ended, the first device 210 may transmit the second indication and wait for confirmation from the second device 220. After the second device 220 received the second indication from the first device 210, the second device 220 may release the first dedicated resource directly and then indicate ACK to the first device 210. When the first device 210 receives ACK, the first device 210 may release the first dedicated resource.
[0162] In some implementations, if the first dedicated resource is not enough for the first device 210 to perform the first DO-A data transmission, the first device 210 may transmit, to the second device 220, a third indication indicating more resources need to be allocated.
[0163] In some implementations, the third indication may be one-bit to indicate to the second device 220 more resource needs to be allocated, or further indicate a data size for the first DO-A data transmission or a traffic pattern for the first DO-A data transmission for more accurate resource configuration.

The at least one D2R resource is used for the at least one device to transmit DO-A assistance information to the second device 220 to request the at least one resource dedicated for the at least one device for DO-A data transmission.
[0168] In some implementations, the second device 220 may transmit the second resource configuration information via an R2D message newly defined for Release 20 AIoT devices which cannot be decoded by legacy Release 19 AIoT devices. Alternatively, the second device 220 may transmit the second resource configuration information via a legacy R2D message defined in Release 19, e.g., paging message and so on, which can be decoded by both Release 19 AIoT devices and Release 20 AIoT devices.
[0169] In some implementations, if the newly defined R2D message is used, a new message type is introduced for the R2D message.

[0174] Alternatively, in some implementations, the at least one resource used for transmission of the DO-A assistance information is pre-configured by an R2D message, the second device 220 provides the pre-configuration based on the CN assistance information or based on implementation.
[0175] In such implementations, the first device 210 may monitor the R2D message comprising the pre-configuration as long as it is powered on.
[0176] In such implementations, the first device 210 may transmit the first DO-Aassistance information if there is an available D2R resource for transmission and if there is incoming DO-A data or the DO-A data is available.
[0177] Alternatively, in some implementations, the second device 220 may transmit, based on the CN assistance information, at least one dedicated / pre-configured resource for each device with at least one DO-A traffic or with one of the at least one DO-A traffic to transmit the DO-A assistance information.
[0178] In such implementations, the second device 220 may include a resource for each device with DO-A traffic used to indicate the DO-A assistance information. For example, one-bit can be allocated for each device.
[0179] In some implementations, if there is incoming DO-A data or the DO-A data is available at the first device 210, the first device 210 may use the pre-configured one-bit to transmit the first DO-A assistance information to the second device 220.
[0180] In such implementations, the second device 220 can identify the first device 210 based on the resource used for transmitting the DO-A assistance information, and then allocate the first dedicated resource for the first device 210 for further DO-A data transmission.
[0181] Alternatively, in some implementations, the second device 220 may enable any available D2R resource can be used for the transmission of the DO-A assistance information.
[0182] In such implementations, the first device 210 may monitor any R2D message which includes available resource for D2R transmission, and use the available resource to transmit the first DO-A assistance information if there is incoming DO-A data or the DO-A data is available.
[0183] With continued reference to Fig. 4, the first device 210 transmit 430, on a second D2R resource, the first DO-A assistance information to request the first dedicated resource.
[0184] In some implementations, the first device 210 may transmit the first DO-A assistance information if there is incoming DO-A data or the DO-A data is available.
[0185] Alternatively, in some implementations, the first device 210 may transmit the first DO-A assistance information if there is trigger from the second device 220.

[0188] In some implementations, the ID of the first device 210 may comprise one of the following: · a permanent device ID of the first device 210; · a partial ID of the first device 210, wherein the partial ID is a truncated unique part from the permanent device ID based on a predetermined algorithm; · a random ID generated by the first device 210; or · an access stratum (AS) ID of the first device 210.
[0189] Alternatively or additionally, in some implementations, the first DO-A assistance information may comprise a fourth indication that DO-A data is available. For example, the first DO-A assistance information may comprise 1-bit indicating DO-A data is available.

[0195] In some implementations, the pattern of the DO-A traffic may be periodic, or one-shot.
[0196] Upon receiving the DO-A assistance information, the second device 220 transmits 440, based on the DO-A assistance information, the first R2D message to the at least one device. The at least one device may comprise the first device 210.
[0197] The first R2D message comprises the first resource configuration information. The first resource configuration information may comprise at least one resource dedicated for the at least one device (i.e., at least one dedicated resource) to perform at least one DO-A data transmission.

[0201] In some implementations, the information related to the at least one dedicated resource may further comprise at least one ID of the at least one resource.
[0202] In some implementations, the at least one resource is configured with a fixed or default size.
[0203] In some implementations, the at least one resource is configured with a valid timer or a valid duration. The valid duration may be the number of resource (s) in time domain. When the first device 210 receives the first dedicated resource with a first valid timer, the first device 210 starts the first valid timer. When the second device 220 transmits the first dedicated resource with the first valid timer, the second device 220 starts the first valid timer. If the first valid timer expires, both the first device 210 and the second device 220 may release the first dedicated resource.
[0204] In some implementations, the first resource configuration information may indicate association between the at least one dedicated resource and the information related to the at least one device.
[0205] In some implementations, if the information related to the at least one device comprises at least one permanent device ID or paging ID of the at least one device, the second device 220 allocates at least one dedicated resource for each permanent device ID or paging ID. Thus, the first resource configuration information may indicate association between the at least one dedicated resource and each permanent device ID or paging ID.
[0206] Alternatively, in some implementations, if the information related to the at least one device comprises at least one partial ID of the at least one device, the second device 220 allocates at least one dedicated resource for each partial ID.

[0207] Alternatively, in some implementations, if the information related to the at least one device comprises at least one AS ID of the at least one device, the second device 220 allocates at least one dedicated resource for each AS ID. Thus, the first resource configuration information may indicate association between the at least one dedicated resource and each AS ID.
[0208] In some implementations, each device may generate a random ID when the device transmits the DO-A assistance information, and the DO-A assistance information comprises the random ID. For example, the first device 210 may generate a random ID when the first device 210 transmits the first DO-A assistance information, and the first DO-A assistance information comprises the random ID of the first device 210.
[0209] The second device 220 receives the first DO-A assistance information with the random ID and confirms the random ID when providing the first dedicated resource targeted to the first device 210. Then, the random ID is confirmed as the AS ID of the first device 210, and is used to identify the data transmission between the first device 210 and the second device 220.
[0210] Alternatively, in some implementations, the AS ID is assigned by the second device 220 during the AIoT device registration procedure in the case of the second device 220 is involved in the procedure. Then, the AS ID is aligned between the first device 210 and the second device 220 during the registration procedure. The first device 210 includes the AS ID of the first device 210 in the first DO-A assistance information, and the second device 220 allocates the first dedicated resource to the first device 210 by using the AS ID.
[0211] Alternatively, in some implementations, the AS ID may also be assigned during the inventory or command procedure.
