AI Technical Summary
Existing communication networks face challenges in managing Ambient IoT (AIoT) transmissions due to high interference and complexity, particularly in scheduling methods that either require full network control with increased overhead or lack coordination leading to collisions.
Implementing a semi-autonomous method where devices receive information about transmission and reception windows from a network device, allowing AIoT activities to be controlled within these windows, reducing interference and maintaining network control over resource allocation.
This approach reduces interference and collision issues while allowing efficient activation and deactivation of AIoT devices, balancing network control with device autonomy.

Furthermore, the communications between a terminal device and a network device of a cellular network may be performed according to any suitable communication protocols, including, but not limited to, the fourth generation (4G) , 4.5G, the future fifth generation (5G) communication protocols, and / or any other protocols either currently known or to be developed in the future.

Given the rapid development in communications, there will of course also be future type communication technologies and systems with which the present disclosure may be embodied. It should not be seen as limiting the scope of the present disclosure to only the aforementioned system.
[0043] As used herein, the term “network device” refers to any device in a cellular network via which a terminal device accesses a data network and receives services exposed by other network devices of the cellular network. In some examples, a network device may comprise or implement a network function of a 5th generation communication system (5GS) (e.g., a core network) of a cellular network. In some examples, the network devices may be located at the RAN of the 5GS. The network device may be part of a satellite, a base station (BS) or an access point (AP) , for example, a node B (NodeB or NB) , an evolved NodeB (eNodeB or eNB) , a NR NB (also referred to as a gNB) , a Remote Radio Unit (RRU) , a radio header (RH) , a remote radio head (RRH) , a relay, a low power node such as a femto, a pico node, and so forth, depending on the applied terminology and technology. A gNB may include a centralized unit CU and one or more distributed DUs. Femto and Pico nodes are small base stations with a small coverage area.
[0044] The term “terminal device” refers to a device of a communication system of a cellular network, such as a 5th generation communication system (5GS) that may be capable of wireless (e.g., radio) communication with a NR-RAN of the 5GS) . By way of example rather than limitation, a terminal device may also be referred to as a wireless communication device, user equipment (UE) , a Subscriber Station (SS) , a Portable Subscriber Station, a Mobile Station (MS) , or an Access Terminal (AT) . Examples of a terminal device include, but not limited to, a mobile phone, a cellular phone, a smart phone, voice over IP (VoIP) phones, wireless local loop phones, a tablet, a wearable terminal device, a personal digital assistant (PDA) , portable computers, desktop computer, image capture terminal devices such as digital cameras, gaming terminal devices, music storage and playback appliances, vehicle-mounted wireless terminal devices, wireless endpoints, mobile stations, laptop-embedded equipment (LEE) , laptop-mounted equipment (LME) , USB dongles, smart devices, wireless customer-premises equipment (CPE) , an Internet of Things (IoT) device, a watch or other wearable, a head-mounted display (HMD) , a vehicle, a drone, a medical device and applications (for example, remote surgery) , an industrial device and applications (for example, a robot and / or other wireless devices operating in an industrial and / or an automated processing chain contexts) , a consumer electronics device, a device operating on commercial and / or industrial wireless networks, and the like. In the following description, the terms “terminal device” , “communication device” , “terminal” , “user equipment” and “UE” may be used interchangeably.
[0045] There are in general two typical scheduling methods for wireless system for Ambient (AIoT) transmissions. The first method is schedule based option. In this option, gNB has full control of the AIoT system related activities, including e.g., when the intermediate node activates the AIoT device; when the AIoT device performances the transmission; when the intermediate node receives the transmission from AIoT device.
[0046] As every transmission can be coordinated by the gNB, the main advantage for this option is less collision probability. However, it also introduces additional complexity and overhead. For example, before each AIoT transmission, the intermediate node may need to request radio resource from gNB. Then, the gNB needs to send scheduling information to activator, reader and potential AIoT device. Such additional signaling will not only reduce the spectrum efficiency but also the increase the complexity of A-IoT device.
[0047] The second method is autonomous based option. In this option, intermediate node (e.g.., activator) itself makes decision of when to perform transmission. Since the transmit power of AIoT communication is relative low, the autonomous manner may bring the benefit of frequency reuse. However, without the coordination from gNB, the AIoT signalings may create interference to normal communication and other AIoT communications. In addition, as gNB does not know when the intermediate node will activate AIoT device, the BS may schedule transmission to / from the intermediate node, which may confuse its behavior. So, such mis-alignment (between Uu and AIoT transmissions) will cause interference / collision issue. Based on above analysis of problems in both scheduling options, it may be good to implement a hybrid method.
[0048] In view of the above, example embodiments of the present disclosure provide a solution for transmission and receiving windows for device. In the example embodiments of the present disclosure, a first device may receive, from a third device, first information associated with a transmission window for the first device. The first device may perform, based on the first information, a first signal transmission to a fourth device. In this way, a semi-autonomous manner for support AIoT transmissions within cellular network is implemented. Support of the efficient activation or deactivation of Ambient IoT device may be under a proper control of the network. More specifically, AIoT activities are restricted within a window, which is controlled by the gNB. Then, the gNB can schedule Uu communication channels or signalings outside the window to insure low interference. If the gNB has higher priority data to be transmitted, it may also schedule the data within the window. With the priority indication, the intermediate knows how to react the collision issue. Therefore, gNB has relatively a loose control for AIoT activities, while it may control the resources and interference levels.
[0049] FIG. 1 illustrates an example of a network environment 100 in which example embodiments of the present disclosure can be implemented. The environment 100a may be a part of a communication network and comprise a plurality of devices, such as a first device 110, a second device 120, a third device 130 and a fourth device 140. As an example, the first device 110 may be implemented as an activator associated with an Internet of things (IoT) device, a UE device, or an Access Terminal device etc. The second device 120 may be implemented as a reader associated with an Internet of things (IoT) device, a UE device, or an Access Terminal device etc. The third device 130 may be implemented as a network device or a base station (BS) , etc. The fourth device 140 may be implemented as a IoT device or an ambient IoT device, etc. The first device 110, the second device and / or the fourth device 140 may transmit various data to the third device 130 via network environment 100.
[0050] To transmit data and / or control information, the first device 110, the second device and / or the fourth device 140 may perform communications with the third device 130. A link from the first device 110, the second device and / or the fourth device 140 to the third device 130 is referred to as an uplink (UL) , while a link from the third device 130 to the first device 110, the second device and / or the fourth device 140 is referred to as a downlink (DL) .
[0051] The fourth device 140 may be an AIoT device, for example, a tag. The tag may be reflective, i.e., the tag may be able to receive signals from, for example, the first device 110, and reflect signals to, for example, the second device 120. The fourth device 140 may collect data and transmit the data via reflection signals to the second device 120. The first device 110 may be an activator, which, for example, sends activation signals to the fourth device 140 to activate the fourth device 140. For example, the activation signals may be or may comprise signals to facilitate an AIoT device synchronization, and / or to help to identify transmission target (transmission recipient) or transmission purpose, and / or to deliver message / data to an AIoT device, and / to indicate when the transmission starts and when it ends. The second device 120 may be a reader, which, for example, receives data (for example, via reflection signals) from the fourth device 140, and, in some circumstances, forwards the data to the third device 130. The third device 130 may be a network device, for example, a base station. It is noted that, in the context of this disclosure, the first device 110, the second device 120, the third device 130 and the fourth device 140 may be differentiated with each other by functions they implement, while in physical form the first device 110 and the second device 120 may be implemented in a same device.
[0052] Although the first device 110, the second device, the third device 130 and the fourth device 140 are described in the communication environment 100 of FIG. 1, embodiments of the present disclosure may equally apply to any other suitable communication devices in communication with one another.

In addition, it should be appreciated that there may be various wireless as well as wireline communications (if needed) among all of the communication devices.
[0054] FIG. 2 illustrates a flowchart of method according to some embodiments of the present disclosure. For the purpose of discussion, the method 200 will be described with reference to FIG. 1. It would be appreciated that although the process flow 200 has been described referring to FIG. 1, this process flow 200 may be likewise applied to other similar communication scenarios.
[0055] In the process flow 200, the third device 130 may determine (205) determine a transmission window for a first device 110 and / or a reception window for a second device 120.

[0080] FIG. 3 illustrates a detailed example of interactions 300 between devices in accordance with some example embodiments of the present disclosure. It is noted that FIG. 3 can be deemed as a further example of the process flow 200. For example, the activator 310 may be example devices of the first device 110, the reader 320 may be the example devices of the second device 120, and the gNB 330 may be the example devices of the third device 130. It is to be understood that these devices are described only for the purpose of illustration without suggesting any limitation as to the scope of the disclosure. This process will be described in detail as follows.
[0081] Specifically, at 302, a core network 340 may indicate AIoT traffic characteristic to the gNB 330. The traffic characteristic may include periodicity of the traffic, duration of the traffic, amount of traffic in each occasion.
[0082] The activator 310 and / or the reader 320 may indicate an assistance information to the gNB. In some embodiments, the assistance information may indicate the availability or unavailability of the intermediate node (such as, the activator 310 and / or the reader 320) in time as well as the maximum duration that the intermediate node may dedicate for transmission or reception AIoT related activities. The assistance information may be transmitted by a RRC signaling. For example, the gNB 330 may request the assistance information by transmitting a RRC signaling to the activator 310 and / or the reader 320.
[0083] At 306, the gNB 330 may determine a transmission window for AIoT activator 310 and / or a receiving window for AIoT reader 320 based on AIoT traffic characteristic or collected information received from core network functions application, or intermediate nodes.
[0084] At 308, the gNB 330 may indicate the determined transmission window indication and / or a first priority indication to the activator 310. For example, in some embodiments, the determined transmission window indication may indicate that AIoT activator 310 may be only allowed to perform activation signal transmission within the configured transmission window. The determined transmission window indication and / or priority indication may be also transmitted via a RRC signalling.
[0085] If configured, the AIoT activator 310 may be allowed to not perform a transmission of other UL signals or channels, as the timing between the activator 310 and the AIoT device could be different than the timing between the activator 310 and the gNB 330. In some embodiments, the determined transmission window indication may indicate that the transmission window may be outside the measurement gap, or the transmission window may be outside the UE DRX on-duration.
[0086] In some embodiments, the AIoT activator 310 may prioritize the AIoT activation signal transmission over other signals or channels based on the priority indication. In some embodiments, if the first priority indication is not configured, the AIoT activator 310 may treat the AIoT activation signal as the highest priority compared with other channels or signals. Alternatively, or additionally, the AIoT activator 310 may treat the AIoT activation signal as the lowest priority compared with other channels or signals.
[0087] The priority may be different depending on the purpose of activation. For example, if the A-IoT device is supposed to perform a transmission by backscattering a specific RS so that the reader 320 may perform a measurement, transmission of the activation signal could be deprioritized. However, if the A-IoT device is supposed to perform a transmission by backscattering a specific data / channel, activation signal may have a high priority.
[0088] In some embodiments, the priority may be dependent on states of signals. For example, AIoT activation signal (or AIoT transmissions) may have higher priority than other signals / channels, or the AIoT activation signal (or AIoT transmissions) may have lower priority than other signals / channels.
[0089] In some embodiments, the priority may be dependent on Uu signals and channels. For example, AIoT activation signal (or AIoT transmissions) may have lower priority than critical Uu signals / channels (such as, Synchronization Signal Block (SSB) , system information, control information) , but has higher priority than less-critical Uu signals / channels (such as, Physical Downlink Shared Channel (PDSCH) , Physical Uplink Shared Channel (PUSCH) , etc. ) .
[0090] In some embodiments, the priority may be dependent on content of AIOT transmissions or similar priority rule for AIOT device transmissions. For example, AIOT activation signal for critical message (or other critical AIOT transmissions) may have higher priority than Uu signals and channels. The AIOT activation signal for non-critical message (or other non-critical AIOT transmissions) may lower priority than Uu signals and channels. In some embodiments, the priority may be dependent on any of factors listed above.
[0091] At 312, the activator 310 may determine the occasions to transmit activation signalling based on indicated transmission window and / or priority indication. For example, when transmission of activator signalling is collided with other signalling or channels, the activator 310 may determine detailed behaviour (which signalling to transmit or receive) at least based on the indicated priority indication.
[0092] At 314, the gNB 330 may indicate the determined reception window indication and / or a second priority indication to AIoT reader 320. For example, in some embodiments, the determined reception window indication may indicate that the AIoT reader 320 may be only allowed to receive transmissions from AIoT devices within the configured receiving window. In some embodiments, the determined reception window indication may indicate that the reception window may be outside the measurement gap, or the reception window may be outside the UE DRX on-duration.
[0093] In some embodiments, the AIoT reader 320 may prioritize the reception of AIoT transmissions over other signals or channels based on the priority indication. In some embodiments, if the second priority indication is not configured, the AIoT reader 320 may treat the AIoT transmissions as the highest priority compared with other channels or signals. Alternatively, or additionally, the AIoT reader 320 may treat the AIoT transmissions as the lowest priority compared with other channels or signals.
[0094] At 316, the AIoT reader 320 may determine the occasions to receive AIoT device data transmissions based on indicated receiving window and / or priority indication. For example, when receiving of AIoT device data transmission is collided with other signaling / channels, the reader 320 may determine detailed behavior (which signaling to transmit or receive) at least based on the indicated priority indication.
[0095] In some further embodiments, on top of the transmission window for AIoT activator 310 and / or a reception window for AIoT reader 320, the gNB 330 may indicate the activator 310 to perform a sensing and compare a level of the signal strength (e.g., Received Signal Strength Indication (RSSI) or Reference Signal Received Power (RSRP) ) to a provided threshold. If the sensing result is less than the threshold, the activator is allowed to activate the AIoT device. The sensing criterion may be configured for a specific BWP or resource blocks (RBs) . The A-IoT device may not be able to hear the activation signal if there are interference signals above a certain level.
[0096] In some embodiments, the transmission window and the reception window may be a time domain window in unit of e.g., absolute time unit (e.g., ms) , or system time unit (e.g., symbols / slots) . In some embodiments, the transmission window and the reception window may be a frequency domain window.
