[0053] Turning to FIG. 1, this figure shows a block diagram of one possible and nonlimiting example in which the examples may be practiced. A user equipment (UE) 110, radio access network (RAN) node 170, and network element(s) 190 are illustrated. In the example of FIG. 1, the user equipment (UE) 110 is in wireless communication with a wireless network 100. A UE is a wireless device that can access the wireless network 100. The UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected through one or more buses 127. Each of the one or more transceivers 130 includes a receiver, Rx, 132 and a transmitter, Tx, 133. The one or more buses 127 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, fiber optics or other optical communication equipment, and the like. A “circuit” may include dedicated hardware or hardware in association with software executable thereon. The one or more transceivers 130 are connected to one or more antennas 128. The one or more memories 125 include computer program code 123. The UE 110 includes a module 140, comprising one of or both parts 140- 1 and/or 140-2, which may be implemented in a number of ways. The module 140 may be implemented in hardware as module 140-1, such as being implemented as part of the one or more processors 120. The module 140-1 may be implemented also as an integrated circuit or through other hardware such as a programmable gate array. In another example, the module 140 may be implemented as module 140-2, which is implemented as computer program code 123 and is executed by the one or more processors 120. For instance, the one or more memories 125 and the computer program code 123 may be configured to, with the one or more processors 120, cause the user equipment 110 to perform one or more of the operations as described herein. The UE 110 communicates with RAN node 170 via a wireless link 111.

[0054] The UE may also be able to communicate with other UE via link 145. For example, the UE may communicate with other UE via sidelink signaling, Bluetooth™ signaling, and/or direct signaling.

[0055] The RAN node 170 in this example is a base station that provides access by wireless devices such as the UE 110 to the wireless network 100. The RAN node 170 may be, for example, a base station for 5G, also called New Radio (NR). In 5G, the RAN node 170 may be a NG-RAN node, which is defined as either a gNB or a ng-eNB. A gNB is a node providing NR user plane and control plane protocol terminations towards the UE, and connected via the NG interface to a 5GC (such as, for example, the network element(s) 190). The ng-eNB is a node providing E-UTRA user plane and control plane protocol terminations towards the UE, and connected via the NG interface to the 5GC. The NG-RAN node may include multiple gNBs, which may also include a central unit (CU) (gNB-CU) 196 and distributed unit(s) (DUs) (gNB-DUs), of which DU 195 is shown. Note that the DU may include or be coupled to and control a radio unit (RU). The gNB-CU is a logical node hosting RRC, SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that controls the operation of one or more gNB-DUs. The gNB-CU terminates the Fl interface connected with the gNB-DU. The Fl interface is illustrated as reference 198, although reference 198 also illustrates a link between remote elements of the RAN node 170 and centralized elements of the RAN node 170, such as between the gNB-CU 196 and the gNB- DU 195. The gNB-DU is a logical node hosting RLC, MAC and PHY layers of the gNB or en-gNB, and its operation is partly controlled by gNB-CU. One gNB-CU supports one or multiple cells. One cell is supported by only one gNB-DU. The gNB-DU terminates the Fl interface 198 connected with the gNB-CU. Note that the DU 195 is considered to include the transceiver 160, e.g., as part of a RU, but some examples of this may have the transceiver 160 as part of a separate RU, e.g., under control of and connected to the DU 195. The RAN node 170 may also be an eNB (evolved NodeB) base station, for LTE (long term evolution), or any other suitable base station, access point, access node, or node. [0056] The RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N/W I/F(s)) 161, and one or more transceivers 160 interconnected through one or more buses 157. Each of the one or more transceivers 160 includes a receiver, Rx, 162 and a transmitter, Tx, 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. The CU 196 may include the processor(s) 152, memories 155, and network interfaces 161. Note that the DU 195 may also contain its own memory/memories and processor(s), and/or other hardware, but these are not shown.

[0057] The RAN node 170 includes a module 150, comprising one of or both parts 150- 1 and/or 150-2, which may be implemented in a number of ways. The module 150 may be implemented in hardware as module 150-1, such as being implemented as part of the one or more processors 152. The module 150-1 may be implemented also as an integrated circuit or through other hardware such as a programmable gate array. In another example, the module 150 may be implemented as module 150-2, which is implemented as computer program code 153 and is executed by the one or more processors 152. For instance, the one or more memories 155 and the computer program code 153 are configured to, with the one or more processors 152, cause the RAN node 170 to perform one or more of the operations as described herein. Note that the functionality of the module 150 may be distributed, such as being distributed between the DU 195 and the CU 196, or be implemented solely in the DU 195.

[0058] The one or more network interfaces 161 communicate over a network such as via the links 176 and 131. Two or more gNBs 170 may communicate using, e.g., link 176. The link 176 may be wired or wireless or both and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interface for other standards.

[0059] The one or more buses 157 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, fiber optics or other optical communication equipment, wireless channels, and the like. For example, the one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for LTE or a distributed unit (DU) 195 for gNB implementation for 5G, with the other elements of the RAN node 170 possibly being physically in a different location from the RRH/DU, and the one or more buses 157 could be implemented in part as, for example, fiber optic cable or other suitable network connection to connect the other elements (e.g., a central unit (CU), gNB-CU) of the RAN node 170 to the RRH/DU 195. Reference 198 also indicates those suitable network link(s).

[0060] It is noted that description herein indicates that “cells” perform functions, but it should be clear that equipment which forms the cell will perform the functions. The cell makes up part of a base station. That is, there can be multiple cells per base station. For example, there could be three cells for a single carrier frequency and associated bandwidth, each cell covering one-third of a 360 degree area so that the single base station’s coverage area covers an approximate oval or circle. Furthermore, each cell can correspond to a single carrier and a base station may use multiple carriers. So if there are three 120 degree cells per carrier and two carriers, then the base station has a total of 6 cells.

[0061] The wireless network 100 may include a network element or elements 190 that may include core network functionality, and which provides connectivity via a link or links 181 with a further network, such as a telephone network and/or a data communications network (e.g., the Internet). Such core network functionality for 5G may include access and mobility management function(s) (AMF(s)) and/or user plane functions (UPF(s)) and/or session management function(s) (SMF(s)). Such core network functionality for LTE may include MME (Mobility Management Entity)/SGW (Serving Gateway) functionality. These are merely illustrative functions that may be supported by the network element(s) 190, and note that both 5G and LTE functions might be supported. The RAN node 170 is coupled via a link 131 to a network element 190. The link 131 may be implemented as, e.g., an NG interface for 5G, or an SI interface for LTE, or other suitable interface for other standards. The network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N/W I/F(s)) 180, interconnected through one or more buses 185. The one or more memories 171 include computer program code 173. The one or more memories 171 and the computer program code 173 are configured to, with the one or more processors 175, cause the network element 190 to perform one or more operations.

[0062] The wireless network 100 may implement network virtualization, which is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, a virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is categorized as either external, combining many networks, or parts of networks, into a virtual unit, or internal, providing network-like functionality to software containers on a single system. For example, a network may be deployed in a tele cloud, with virtualized network functions (VNF) running on, for example, data center servers. For example, network core functions and/or radio access network(s) (e.g. CloudRAN, O-RAN, edge cloud) may be virtualized. Note that the virtualized entities that result from the network virtualization are still implemented, at some level, using hardware such as processors 152 or 175 and memories 155 and 171, and also such virtualized entities create technical effects.

[0063] It may also be noted that operations of example embodiments of the present disclosure may be carried out by a plurality of cooperating devices (e.g. cRAN).

[0064] The computer readable memories 125, 155, and 171 may be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory and removable memory. The computer readable memories 125, 155, and 171 may be means for performing storage functions. The processors 120, 152, and 175 may be of any type suitable to the local technical environment, and may include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs) and processors based on a multi-core processor architecture, as non-limiting examples. The processors 120, 152, and 175 may be means for performing functions, such as controlling the UE 110, RAN node 170, and other functions as described herein.

[0065] In general, the various example embodiments of the user equipment 110 can include, but are not limited to, cellular telephones such as smart phones, tablets, personal digital assistants (PDAs) having wireless communication capabilities, portable computers having wireless communication capabilities, image capture devices such as digital cameras having wireless communication capabilities, gaming devices having wireless communication capabilities, music storage and playback appliances having wireless communication capabilities, Internet appliances permitting wireless Internet access and browsing, tablets with wireless communication capabilities, as well as portable units or terminals that incorporate combinations of such functions. [0066] Having thus introduced one suitable but non-limiting technical context for the practice of the example embodiments of the present disclosure, example embodiments will now be described with greater specificity.

[0067] Features as described herein may generally relate to ambient Internet of Things (A-IoT) devices or user equipments. Ambient loT devices may be described as low power devices, low cost devices, and/or as devices with limited functionality/processing capability. The capabilities of an AIOT device may be reduced even compared to a reduced capability (RedCap) device. An AIOT UE may have reduced or no capability to generate a signal for transmission to another UE or to a network element.

[0068] In the present disclosure, an AIOT device may also be referred to as an A-IoT device, an AIOT UE, a tag, a UE, etc.

[0069] An example of an A-IoT device is a passive radio, which may harness energy from wireless signals sent on specific carriers and/or bandwidths and charge a simple circuitry that, once activated, may emit/reflect a signal, which may encode at least the ID of the passive radio. The typical system architecture around a passive radio consists of an activator, a passive radio, and a reader. The activator is a device that sends an activation signal targeted at waking up the passive radio. The passive radio harnesses energy over a range of frequencies and listens for activation signals. Once such a signal is detected, the passive radio emits/reflects a signal which is specific to that radio ID. The reader is a device that listens and detects the passive radio signals. The reader may or may not be collocated with the activator.

[0070] In the present disclosure, a reader may also be referred to as a reader UE, a reader device, a transmission and/or reception point (TRP), a base station, a gNB, etc.

[0071] Other examples of A-IoT devices include semi-passive devices and battery-less devices. For example, A-IoT device may include battery-less passive radio frequency identification (RFID) devices that are capable of performing backscattering transmission. Also it may include active RFID devices with a limited battery or energy harvesting functionality. The active RFID device may use its own battery to generate transmission signals. In addition, the active device may be able to monitor NR wake-up signals. In case it receives a specific wake-up signal, the active device may be activated to transmit required signals. [0072] It should be noted that backscatter communication, or reflection, is a signal transmission method for loT devices that are battery-less or energy-limited, where a received signal may be modified and/or reflected. When an A-IoT device backscatters a reference signal, it reflects or forwards the reference signal, with or without changes, using energy derived from (other) received signals. For example, the A-IoT device may modulate a radio ID, or other information, onto the received signal. This is in contrast to (direct) transmission of a reference signal, where the reference signal is transmitted using a battery or energy stored at the A-IoT device.

[0073] There are monostatic A-IoT devices and bistatic A-IoT devices. In the case of a bi-static A-IoT device, a transmitter sending a signal to the A-IoT device is different than a receiver receiving the signal. In the case of a monostatic A-IoT device, the transmitter and receiver of transmitting and receiving a A-IoT signal are the same.

[0075] It is noted that the session notes for 9.4. Study on solutions for Ambient loT in NR, Rl-2401767 also included the following:

“...9.4.2.4 Waveform characteristics of carrier-wave provided externally to the Ambient loT device

Case 2-2: CW is transmitted from inside the topology (i.e., intermediate UE), transmitted in UL spectrum

Case 2-3: CW is transmitted from outside the topology, transmitted in DL spectrum

Case 2-4: CW is transmitted from outside the topology, transmitted in UL spectrum. .

[0076] The following connectivity topologies for ambient loT networks and devices were defined for the purposes of the study. In all these topologies, the ambient loT device may be provided with a carrier wave (CW) from other node(s), either inside or outside the topology. The links in each topology may be bidirectional or unidirectional. Base station (BS), UE, assisting node, or intermediate node may be multiple BSs or UEs, respectively. The mixture of indoor and outdoor placement of such nodes may be regarded as a network implementation choice.

[0077] In topology 1, illustrated in FIG. 2, the ambient loT device directly and bidirectionally communicates with a base station. The communication between the base station (210) and the ambient loT device (220) includes ambient loT data and/or signaling. This topology includes the possibility that the BS transmitting to the Ambient loT device may be different from the BS receiving from the Ambient loT device.

[0078] In topology 2, illustrated in FIG. 3, the ambient loT device (330) communicates bidirectionally with an intermediate node (320) between the device (330) and the base station (310). In this topology, the intermediate node may be a relay, IAB node, UE, repeater, etc. which is capable of ambient loT operation. The intermediate node transfers the information between the BS and the ambient loT device.

[0079] Features described herein may generally relate to a carrier wave. A carrier wave is a wave used by the AIOT device to modulate and backscatter the AIOT reply. The CW signal may be a standalone signal. The CW signal may be different from the activation signal; alternatively, the activation signal may embed a CW. The CW signal has the main purpose of carrying the AIOT transmission for those AIOT devices which cannot actively and independently generate a signal of their own (e.g. device types 1 and 2a). In other words, the CW is being transformed (e.g. modulated) by the AIOT device to contain the AIOT payload (e.g. ID, data and other control information, etc.) and reflected (i.e., backscattered) either immediately or with a delay pre-configured by the activator via reader to device (R2D) signal configuration. The CW may be used by multiple AIOT devices.

[0080] The entity generating the CW should be as close as possible, or sufficiently close (e.g. within a minimum distance) to the AIOT device, and should transmit the CW at high enough power, on the correct carrier frequency and for a sufficiently long time, so that: the AIOT device can modulate all its payload onto said CW (i.e. CW is long enough for the payload to be completely provided); and the AIOT reply can be successfully decoded by a reader within the coverage area of said AIOT device.

[0081] The CW may precede the activation signal and/or may be emitted by the same entity as the activation signal. However, the CW node may typically be located closer to the tag/ AIOT device than the activator is.

[0082] The CW signal may be used by the tag to charge the AIOT device enough to be able to process the activation signal.

[0083] Since the proximity of the CW node is paramount to the success of the AIOT session, RAN 1 discussed introducing a separate entity for this sole purpose, where this entity may pe part of either topology 1 or 2, or may be outside the topology. Since the CW transmission can be potentially harmful to other ongoing transmissions - either AIoT or Uu traffic - it may be configured by the NW.

[0084] Examples of the CW node may include an activator, a UE, a base station, a gNB, part of an LMF, an intermediate node, a separate entity, a network node, a network element, a network function, etc. A CW node may also be referred to as a CW element, a CW radio, a CW function, etc. [0085] Example embodiments of the present disclosure may relate to selection of a length of the CW. A technical effect of example embodiments of the present disclosure may be to enable the AIOT device to modulate all its data payload using received CW.

[0086] In an example embodiment, the CW signal may be defined using a fixed duration and a variable repetition size B (e.g. number of repetitions). A single instance of the CW signal may have a predefined length, and this instance may be repeated in time up to B times. The repetition size B may be based on the outcome of a reading session (e.g. feedback from a reader), or based on feedback from a tag/AIOT device (or any NR entity) with respect to one or more AIOT devices, each of which may have a variable pay load to convey via one or more repetitions of CW. The repetition size B may be configured and/or adjusted by the NW.

[0087] In an example embodiment, the CW repetition size may be dynamically adapted. A technical effect of example embodiments of the present disclosure may be to ensure that one or more AIOT devices may successfully transmit all their payload information.

[0088] In an example embodiment, the adaptation of the repetition size B may be performed by the CW node during the time gaps between two CW transmissions.

[0089] In an example embodiment, the adaptation of the repetition size B may be performed by the CW node may be triggered by either: the NW, or the AIOT device itself. In an example embodiment, the NW may trigger repetition size adaptation based on feedback received from one or more readers, or potentially directly from an AIOT device, about the outcome of the most recent AIOT reading session. In an example embodiment, the AIOT device may trigger repetition size adaptation, when capability allows for it, via a set of binary flags, which may indicate the need for a subsequent CW transmission or the need for a certain number of subsequent CW transmissions.

[0090] The repetition size B may be considered a maximum number of CW repetitions that are allowed to be made by the CW node.

[0091] It may be assumed that the AIOT device sends a message bit vector u. The message may (optionally) be encoded and modulated, for example on-off keying (OOK) modulated into the symbol s = [s_p The symbol vector s is converted to analog domain to yield a signal s(t) = £fc₌₁ s_k c[> (t — kT_s), t = [0, T), where T is the symbol duration, T = KTs, Ts is the sampling time, and <|) is a shaping filter whose implementation depends on the AIOT device type. T may depend, for example, on a type of an AIOT device.

[0092] The signal s(t) needs to be carried by a CW, which is here, for simplicity, considered a single tone i.e., exp 2njf_ct , t = [0, T). The transmitted wave is then: y(t) = s(t) exp(27Tj f_ct) , t e [0, T)

[0093] Thus, the duration of the CW may be at least equal to T, for example to ensure all payload is transmitted. However, T is apriori unknown to the CW node. Furthermore, the CW node may need to serve multiple AIOT devices, each with a different duration T i.e., Tl,..., Tn. In addition, each AIOT device may have multiple symbols to send i.e.

Thus, selecting a duration for the CW is challenging. To cope with these challenges, the CW node may employ one of the following example embodiments.

[0094] In an example embodiment, the CW node may transmit a repetition of B CW signals, each repetition b = 1:B being of fixed duration T_avg, where T_avg is the average duration of the expected AIOT transmission. Referring now to FIG. 4, illustrated is an example of signaling according to an example embodiment of the present disclosure.

[0095] At 405, the NW may configure the CW signal. The CW signal may be, for example, a single tone or a multi tone signal. The configuration for the CW signal may include a duration T_avg, a repetition number B, and/or a time domain pattern.

[0096] T_avg may depend at least on the AIOT device type (e.g. type 1, 2a). Thus, three different values for T_avg may be standardized or predefined. In a configuration of CW generation and/or transmission, the duration of the CW may be a fixed value. Alternatively, the duration of the CW may be reconfigured by the NW.

[0097] In an example embodiment, the repetition size B may be fixed to a conservative value. A technical effect of using a conservative value may be to ensure that a payload of max Nbits can be transmitted. Nbits may be selected as IK, 2K bits, etc.

[0098] In an example embodiment, the repetition size B may be variable. For example, the repetition size B may be configured by the NW according to the number and/or type of AIOT devices to be served. The value B may be dynamically changed, for example when these repetitions are not consecutive in time (i.e. when there is a time gap between repetition b and b+1). In this case, during said time gap, the NW may increase or decrease the value of B depending on the outcome of the most recent AIOT reading session.

[0099] The time domain pattern may comprise consecutive repetition of the CW signal. Alternatively, the time domain pattern may comprise repeating transmission of the CW signal with a time offset T_gap. Alternatively, the time domain pattern may comprise consecutive repetition of the CW signal a certain number of times, followed by repeated transmission of the CW signal with a time offset T_gap between each following transmission. In the present disclosure, the term “timing pattern” may refer to a pattern of consecutive CW signal transmission without a time offset between transmissions, or a pattern of CW signal transmissions with time offsets that occur either periodically or between a certain number of CW signal transmission(s).

[00100] At 410, the CW node may perform consecutive repetitions of the CW signal, to the AIOT device, B times. At 415, the CW node may transmit, to the AIOT device, the CW signal a first time. At 420, the CW node may transmit, to the AIOT device, the CW signal a second time. At 425, the CW node may transmit, to the AIOT device, the CW signal a Bth time.

[00101] In an example embodiment, the CW signal generation (e.g. at 410) may be standardized in TS 38.211 as a reference signal transmission (in either UL or DL), and the configuration describing the signal generation (e.g. at 405) may be carried by a new RRC IE or MAC CE.

[00102] At 430, the CW node may perform consecutive repetitions of the CW signal according to the configuration of the CW signal. The CW transmission performed at 430 may be a continuation of the CW transmission at 410, or may be an alternative example of CW transmission in contrast to the CW transmission illustrated at 410. At 435, the CW node may transmit, to the AIOT device, the CW signal a first time. At 440, the CW node may insert a time gap T_gap, and may monitor or listen for a (potential) reconfiguration with respect to CW signal transmission.

[00103] In an example embodiment, the placement/insertion of the time gap T_gap may be variable. For example, the time domain pattern may indicate that the time gap is to be inserted at certain time intervals, or after a certain number of CW signal transmissions (e.g. after all B CW signals have been transmitted, after each CW signal transmission, after two consecutive CW signal transmissions, etc.). In the example of FIG. 4, the time gap is inserted after each CW signal following CW signal transmission at 435, but this example is not limiting.

[00104] At 445, the NW may determine to update B to B_new based, for example, on reader feedback or AIOT device feedback. At 450, the NW may transmit, to the CW node, a reconfiguration of B to B_new. The CW node may update or overwrite B to B_new, and proceed with transmitting CW to the AIOT device as long as fewer than B_new CW have been transmitted to the AIOT device.

[00105] Additionally, the NW may determine to update T_gap, and reconfigure the CW node with a new value for T_gap.

[00106] In the example of FIG. 4, the CW node may transmit, to the AIOT device, the CW signal a second time. At 460, the CW node may insert a time gap T_gap, and may monitor or listen for a (potential) reconfiguration with respect to CW signal transmission. After T_gap has elapsed, at 465 the CW node may transmit, to the AIOT device, additional CW. At 470, CW node may insert a time gap T_gap, and may monitor or listen for a (potential) reconfiguration with respect to CW signal transmission. At 475, the CW node may transmit, to the AIOT device, the B_new-th CW signal, and stop transmitting CW to the AIOT device.

[00107] In an example embodiment, the CW node may continue with a single counter for CW signal transmission/repetition. For example, if the CW node has been configured to transmit CW six times, and after transmitting CW three times B is reconfigured to have a value of five, the CW node may proceed to transmit CW two more times.

[00108] After the CW repetition has been configured (e.g. at 405) and the CW node executes the transmission (e.g. at 410), the reader may attempt to detect the AIOT device reply. In an example embodiment, the reader may count the number of CW repetitions B0<=B after which it has successfully decoded the reply, and may report B0 to the NW via a new RRC IE, for example in a physical uplink shared channel (PUSCH) pre-configured transmission, together with the reading outcome. Conversely, if the reader has failed to read the AIOT device, the reader may indicate failure. [00109] In an example embodiment, the NW may use the report to configure B_new as either BO, or, in case of failure, to increase the repetition size by a default Bdelta value: B_new = B + Bdelta.

[00110] Note that if the NW entity controlling the session is the LMF, then the reader report, containing B0, may be done/transmitted via a new IE in “LPP ProvideLocationlnformation”, while the LMF reconfiguration of B_new may be carried by a new IE in LPP AssistanceData.

[00111] In an example embodiment, the CW duration may be configured based on a request and/or feedback from the AIOT device itself, when said capability exists at the AIOT device side.

[00112] For example, in the control field of the physical device to reader channel (PDRCH) at transmission time N, the AIOT device may pre-request a CW duration/repetition for the transmission time N+L The request may be carried by a field in the control part of the PDRCH as a first (binary) variable, where a value of “1” may indicate that a subsequent CW signal is needed during N+l. Additionally or alternatively, the AIOT device may indicate that it has not yet finished transmitting its data payload. A value of “0” may indicate that no further CW signals need be transmitted. Optionally, a second variable may be included which may indicate the number of CW repetitions required to finalize the AIOT transmission. For example, the second variable may indicate how many more packets the AIOT device expects to send.

[00113] Since the PDRCH is received by the reader, the reader may forward the repetition request to the CW node, either directly or via the NW (e.g. serving gNB). The reader may act as a relay.

[00114] Referring now to FIG. 5, illustrated is an example of signaling to configure CW signal transmission according to an example embodiment of the present disclosure. At 510, the AIOT device may transmit, to the reader, PDRCH comprising control information for CW signal transmission. The control information may comprise a request with respect to CW repetition, for example a request to repeat CW signal transmission or a request to stop transmitting the CW signal or to not repeat transmission of the CW signal. The control information may further comprise a request that the CW signal transmission be repeated B times.

[00115] At 520, the reader may forward, or determine to send, to the CW node the request to continue CW signal repetition or stop the repetition. Additionally or alternatively, the reader may transmit, to the CW node, a requested number of repetitions B of the CW signal.

[00116] The reader may forward the request to the CW node either directly, for example if the CW node is the gNB, or indirectly, via the NW unit controlling the session (e.g. LMF). In the former case, the request may be sent via new RRC IE, while in the latter case, the request may be sent as either a new IE in an LPP Request Assistance Data when the reader is a UE, or as a new IE in NRPPa Request Assistance Data when the reader is a TRP. Alternatively, the information may be transmitted between the reader and the CW node via sidelink communication.

[00117] In an example embodiment, the AIOT device request to the reader may be contained in the data or control parts of the PDRCH channel, which is currently under standardization.

[00118] In an example embodiment, the CW node may operate according to a received (re)configuration for CW signal transmission. Referring now to FIG. 6, illustrated is an example of CW node behavior. While not illustrated in FIG. 6, the CW node may receive a configuration for CW signal generation and/or transmission, for example as described above with respect to FIG. 4. The CW node may receive the configuration from a relay, or directly from the network.

[00119] At 610, the CW node may transmit a repetition b of the CW. At 620, the CW node may switch to reception for a duration of T_gap, during which it may listen or monitor for a potential reconfiguration from the NW. At 630, if a reconfiguration message is received, the CW node may decode the message and retrieve the new value of B, called B_new. At 640, the CW node may then subsequently overwrite or update the value of B based on B_new and proceed, at 650, with transmission b+1, as long as b+1 < B_new, at 660. The CW node may then switch to reception for a duration of T_gap at 620. If b+1 > B_new, then at 670 the CW node may stop transmitting CW to the AIOT device. [00120] While not illustrated in FIG. 6, at 630 the reconfiguration message may further include a reconfiguration of T_gap, in response to which the CW node may change or update the time gaps used to monitor for further reconfiguration messages.

[00121] In an example embodiment, if B_new > B, and the NW element which produced the reconfiguration request is not the serving gNB, then the CW node may request for an additional transmission gap of (B_new-B)x T_avg from its own serving gNB, to finalize the CW repetitions. The transmission gap is used for transmission of the CW signal. Accordingly, the transmission gap may change with/according to the change in the repetition size B.

[00122] In an example embodiment, if B_new <B, and the NW element which produced the reconfiguration request is not the serving gNB, then the CW node may inform the serving gNB that the transmission gap may be shortened to B_new x T_avg.

[00123] While example embodiments of the present disclosure are described in the context of ambient IOT devices, this is not limiting; example embodiments of the present disclosure may also be applicable in the context of IOT devices, or devices for which capabilities are less limited than in the case of ambient IOT devices.
