[0149] In today's Internet of Things networks, traditional Internet of Things devices are usually powered by traditional batteries with limited lifetime, which negatively impacts user experience. In some extreme environmental conditions, it can be very challenging to maintain the operation of the Internet of Things network and replace the battery. In this regard, battery-free Internet of Things communication has been proposed, which will improve network performance and sustainability and expand application scenarios. In addition, by removing traditional batteries, device size and cost can be significantly reduced, providing a foundation for a variety of new applications.
[0150] In the 5G era, various LPWA (Low Power Wide Area) technologies such as MTC (Machine Type Communication), NB-IoT (Narrow Band Internet of Things), RedCap (Reduced Capability), etc. have been developed to meet the growing needs of vertical industries. These LPWA technologies enable low cost, low power consumption and large-scale connectivity, meeting the requirements of many applications.
[0151] However, there are still many use cases and applications that cannot be addressed in the following situations. First, devices powered by traditional batteries are not suitable, for example, in extreme environmental conditions (e.g. high pressure, extremely high / low temperature, humid environment). Second, maintenance-free devices are required (e.g. without replacing the traditional batteries of the device). Finally, ultra-low complexity, very small device size / form factor (e.g. thickness of mm), longer life cycle, etc. are required.
[0152] Environmentally powered Internet of Things is a promising technology that can meet the above unmet needs. Environmentally powered Internet of Things devices are Internet of Things devices powered by energy harvesting, with no battery or limited energy storage capacity (e.g. using capacitors), providing energy by harvesting radio waves, light, motion, heat or any other suitable power source.
[0153] The energy obtained from the environment can drive the data transmission and wireless communication of the perception node. The transmit and receive power consumption of the current mainstream low-power Internet of Things communication chips (such as BLE, LoRa, NB-IoT) is in the tens of milliwatts or even hundreds of milliwatts, while the energy harvested from the environment is only in the order of microwatts, which cannot drive these types of nodes to work. Therefore, a new wireless communication technology is needed to reduce the communication energy consumption to tens of microwatts or even below ten microwatts. The current mainstream way is to use backscatter communication technology. Backscatter communication is one of the key technologies for building a green and energy-efficient, low-cost, and flexible future Internet of Things, and is an important means to realize "Internet of Everything".
[0154] Backscatter communication is a modulation and transmission technology designed based on the principle of radio frequency signal backscatter, with extremely low power consumption. Backscatter communication was first proposed by Stockman. When radio frequency signals reach the surface of an object, part of them will be reflected. The sending node adjusts the match between the receiving antenna and the impedance according to the information to be sent, enhances the reflection of the incident radio frequency signal, and modulates the sensing data obtained by itself to the reflected signal to complete the transmission of data. This process is similar to a mirror. Compared with other communication technologies, backscatter communication does not require complex radio frequency structures, reduces the use of power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters and other devices, and does not require complex baseband processing. Therefore, the terminal design can be simplified, and the cost of the terminal node can be greatly reduced.
[0155] Backscatter communication has been widely used in RIFD (radio frequency identification) systems, forming many commercial cases. As shown in FIG. 1b, the working principle is that the receiver (generally an RFID reader) sends a radio frequency excitation signal to activate a passive node (generally an RFID electronic tag), and the electronic tag modulates its own information to the radio frequency signal using backscatter communication. The reader receives the reflected signal of the passive electronic tag and demodulates it to achieve information transmission.
[0156] Currently, the FRID technology also has many shortcomings, such as small coverage distance (wireless signals in the communication process will experience double path fading, so the path loss is large and the effective communication distance is short), single channel transmission, the need for strict alignment of the tag, no power control, etc. There is a lot of room for improvement in the communication of RFID technology. It needs to be integrated with the communication system described in FIG. 1a to improve the wireless communication performance of RFID technology in the passive Internet of Things.
[0157] The tag under the passive radio frequency identification technology can also be called passive Internet of Things (Ambient IoT), that is, a passive Internet of Things device. This new type of Internet of Things device has the characteristics of low memory, low processing power, low power, small data transmission, and mass deployment. The environmental Internet of Things device can be maintenance-free and has a long service life (for example, more than 10 years).
[0158] This new type of Internet of Things device needs to collect radio waves transmitted by network nodes to obtain energy to drive itself to work. Therefore, before obtaining energy, the Internet of Things device is usually in an "off" state, that is, a state of being offline. Therefore, the communication system needs to support a data communication mode with shorter transmission time, lower memory consumption, and more convenient terminal management to complete the data communication process as soon as possible.
[0159] The present application is based on the backscatter technology to realize the wireless communication design of the communication based on the environmental energy device.
[0160] The existing network architecture includes the following:
[0161] Topology 1: Direct DL and UL data reception and transmission between Ambient IoT and base station, see FIG. 1c for details.
[0162] Topology 2: Indirect DL and UL data reception and transmission between Ambient IoT and base station, with intermediate nodes forwarding, see FIG. 1d for details.
[0163] In some embodiments, the intermediate node can be a node that provides data forwarding function, or the intermediate node can be a node that assists other devices or nodes in data transmission or reception. For example, at least one of a relay, an Integrated Access and Backhaul (IAB) node, a User Equipment (UE), a repeater, but not limited thereto.
[0164] Topology 3: Direct DL or UL data reception or transmission between Ambient IoT and base station, with assistance nodes on UL or DL, see FIG. 1e for details. The assistance nodes are responsible for receiving or transmitting UL or receiving DL data. For example, at least one of a relay, an IAB, a UE, a repeater, but not limited thereto.
[0165] Topology 4: Direct DL and UL data reception and transmission between Ambient IoT and UE, where the UE is responsible for collecting data and forwarding the collected data to the network side, see FIG. 1f for details.
[0166] It should be noted that the above example of accessing network equipment as base station is only an exemplary access mode, and does not constitute a limitation on the access mode of Ambient IOT device.
[0167] Ambient IoT Device (A-IoT device) can be divided into three types, see FIG. 1g for details, wherein,
[0168] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission.
[0169] Device B: With energy storage, no independent signal generation, i.e. backscatter transmission. The use of stored energy can include amplification of reflected signals.
[0170] Device C: With energy storage, with independent signal generation, i.e. active RF components for transmission.
[0171] To support data transmission of A-IoT devices, one device in the network can support one or more functions:
[0172] 1. Energy Source (ES) function, only for Device Type B and Type C.
[0173] 2. Downlink Transmission (DT) function, sending indication information to A-IoT devices, thereby triggering uplink transmission of A-IoT devices.
[0174] 3. Continuous Wave (CW) function, only for Device A and B. A-IoT devices implement uplink transmission by backscattering CW. CW is actually also an ES, and A-IoT devices can receive CW and store energy.
[0175] 4. Uplink Reception (UR) function, receiving uplink information backscattered by A-IoT devices, or receiving uplink information actively transmitted by A-IoT devices.
[0176] In some embodiments, the device performing the above ES, DT, CW or UR functions can be a UE, a repeater, a relay or a base station, etc.
[0177] In some embodiments, one device can only support one of the above functions; or one device can also support multiple of the above functions at the same time; or one device can also support all of the above functions at the same time.
[0178] In an RFID (Radio Frequency Identification) communication system, from the perspective of usage functions, commands can be divided into three categories: tag Select, Inventory and Access. Among them, Inventory commands include: Query, QueryAdjust, QueryRep, ACK, NAK.
[0179] In some embodiments, one Tag enters Arbitrate state after receiving Query command, which can be regarded as the "Holding state" of the Tag. The value of the corresponding Counter is set according to the Q value in the command, and the value is decreased by 1 each time a Query Reply (QueryRep) command is received. When the value is 0, the Tag will turn to Reply state and backscatter RN16 (16 bits random number). If a confirmation (ACK) message is further received, it is confirmed that the Tag access is successful; otherwise, if an invalid (Invalid) ACK (e.g. NAK) message or an ACK message with an error RN16 is received, or until T2(max) no corresponding command is received, the Tag returns to the waiting state. Wherein, T2(max) is the maximum waiting time of a Tag device, if no feedback from the corresponding reader is received within this time, the Tag returns to the waiting state.
[0180] Specifically,
[0181] 1. After receiving a valid Query command sent by the reader, each Tag selected according to the set standard generates a random number (similar to rolling a die), and each Tag with a random number of zero will generate a response (returning a temporary password RN16, i.e. a 16-bit random number (RN)), and turn to the Reply state; Tags meeting other conditions will change some attributes and flags, thereby exiting the above-mentioned Tag group, which is conducive to reducing repeated identification.
[0182] 2. After receiving a valid QueryAdjust command, each Tag in the Tag group generates a new random number (similar to re-rolling a die), and the others are the same as Query.
[0183] 3. After receiving a valid QueryRep command, only the original random number of each Tag in the Tag group is decreased by 1, and the others are the same as Query.
[0184] 4. Only the single Tag can receive a valid confirmation ACK command (using the above-mentioned RN16, or Handle, i.e. a 16-bit random number temporarily representing the identity of the Tag (this is a security mechanism)), and after receiving it, the Electronic Product Code (EPC) is returned to the reader.
[0185] 5. After receiving a valid NAK command, except for the Ready and Killed states, the other states remain unchanged.
[0186] The existing flowchart of communication between the tag and the reader / writer can be seen in FIG. 1h.
[0187] The network architecture of the embodiments of the present disclosure is topology 2: communication between the A-IoT device (or Tag) and the UE, the UE as an intermediate node, sends data to the network side.
[0188] For the above topology 2, in the current RFID method, when the UE as an intermediate node needs to communicate with the A-IoT device, as shown in FIG. 1i, IoT UL response can occur without any restrictions, at least the following problems exist:
[0189] 1. Since the UE is in an idle state, the UE will miss the IoT UL.
[0190] 2. If the UE needs to listen to the A-IoT device during the DRX off period, this will significantly increase the power consumption of the UE.
[0191] The network architecture of the embodiments of the present disclosure is topology 2, as shown in FIG. 1j, the uplink (Uu DL) and downlink (Uu UL) of the Uu link between the intermediate node and the network side adopt FDD mode, and the forward link (IoT forward Link, IoT FL) and backward link (IoT backforward link, IoT BL) of the A-IoT link between the intermediate node and the A-IoT device adopt TDD mode. The A-IoT link and the Uu link use the same carrier or frequency band.
[0192] In some embodiments, during the DRX on period, the UE can trigger the IoT command transmission in the Uu UL carrier. There is no any impact on the Uu DL operation (such as paging) because the UE can handle DL and UL simultaneously in the case of FDD spectrum.
[0193] In the case that the UE is in the RRC idle state, the A-IoT device will trigger the communication between it and the UE within the DRX duration, which will cause higher power consumption problem.
[0194] In order to overcome the above problems, the following methods can be used:
[0195] 1. Consider the Uu DL operation first and abandon the IoT UL operation (traditional);
[0196] 2. If the UE has free RF chains, the IoT UL operation can be offloaded to other carriers;
[0197] 3. Make the IoT UL operation share the same occasion with the Uu DL operation - this can be achieved by extending the total delay of paging or RRM measurement, or extending the paging interruption duration.
[0198] In some embodiments, the UE can simultaneously transmit IoT DL and receive Uu paging within DRX. Due to FDD, the interference of Uu DL to IoT DL can be negligible.
[0199] The following describes various embodiments of the communication method proposed by the present disclosure in detail based on the wireless communication system described above.

[0381] In some embodiments, improvements can be made based on existing related solutions, for example: in TS 38.133, the following embodiments of improved solutions are proposed.
[0382] Embodiment 1
[0383] 4.2.2.2 Measurement and evaluation of the serving cell
[0384] The UE shall measure the SS-RSRP and SS-RSRQ levels of the serving cell and evaluate the cell selection criterion S defined for the serving cell at least once every M1*N1 DRX cycles.
[0385] Cell selection criterion S: If SMTC period (TSMTC) > 20 ms and DRX cycle ≤ 0.64 seconds, then M1 = 2, otherwise M1 = 1.
[0386] The UE filters the SS-RSRP and SS-RSRQ measurements of the serving cell using at least 2 measurement values. In the set of measurement values used for filtering, the interval of at least two measurement values is at least DRX cycle / 2.
[0387] For a UE not configured with highSpeedMeasFlagFR2-r17, Nserv is specified in Table 4.2.2.2-1. For an FR2 power class 6 UE configured with highSpeedMeasFlagFR2-r17, Nserv is specified in Table 4.2.2.2-2.
[0388] If the UE is not configured with an eDRX_IDLE cycle and the UE has evaluated that the serving cell does not fulfil the cell selection criterion S according to Table 4.2.2.2-1 or Table 4.2.2.2-4 for Nserv consecutive DRX cycles, the UE shall initiate measurements of all neighbour cells indicated by the serving cell regardless of the measurement rules currently limiting the UE's measurement activity.
[0389] If the UE is configured with an enhanced non-active state extended discontinuous reception, eDRX_IDLE, cycle and the UE has evaluated the serving cell not to fulfil the cell selection criteria S for eDRX cycle ≤ 10.24 s, consecutive eDRX cycles according to Table 4.2.2.2-2 and Table 4.2.2.2-3 in Nserv, the UE shall initiate measurements of all neighbour cells indicated by the serving cell regardless of the measurement rules currently limiting the UE's measurement activity.
[0390] If the UE is configured with an eDRX_IDLE cycle and the UE has evaluated the serving cell not to fulfil the cell selection criteria S for eDRX cycle > 10.24 s, consecutive DRX cycles within a single PTW, i.e. according to Table 4.2.2.2-2 and Table 4.2.2.2-3 in Nserv, the UE shall initiate measurements of all neighbour cells indicated by the serving cell regardless of the measurement rules currently limiting the UE's measurement activity.
[0391] For UEs configured with an eDRX_IDLE cycle, Nserv is specified in Table 4.2.2.2-2 for FR1 and in Table 4.2.2.2-3 for FR2.
[0392] If the UE in RRC_IDLE does not find any new suitable cell based on search and measurements using intra-frequency, inter-frequency and inter-RAT information indicated in system information during time T, the UE shall initiate the cell selection procedure for the selected PLMN (Public Land Mobile Network, PLMN) as defined in TS 38.304 [1], where:
[0393] T = 10 s if the UE is not configured with an eDRX_IDLE cycle, or,
[0394] T = MAX(10 s, one eDRX_IDLE cycle) if the UE is configured with an eDRX_IDLE cycle in FR1, or,
[0395] T = MAX(10 s, N1 * eDRX_IDLE cycle) if the UE is configured to have an eDRX_IDLE cycle less than 20.48 s in FR2,
[0396] T = MAX(10 s, one eDRX_IDLE cycle) if the UE is configured with an eDRX_IDLE cycle not less than 20.48 s in FR2
[0397] Table 4.2.2.2-1: Nserv
[0398] It should be understood that in this embodiment, the parameter Sf can correspond to the first spreading factor above.
[0399] Embodiment 2
[0400] 4.2.2.6 Maximum interruption for paging reception
[0401] The UE shall perform cell reselection with minimum interruption while monitoring the downlink channel for paging reception. In addition, when the UE is configured with eDRX_IDLE period, the UE shall not miss any paging in the PTW if the paging is transmitted at least 2 DRX cycles before the end of the PTW.
[0402] At intra- and inter-frequency cell reselection, the UE shall monitor the downlink of the serving cell for paging reception until the UE is able to start monitoring the downlink channel of the target intra- and inter-frequency cell for paging reception. The interruption time shall not exceed T SI-NR + 2 * Ttarget cell_SMTC_period ms. Where Ttarget cell_SMTC_period is the period of SMTC occasions configured for the target NR cell. If the target cell is in the optional physical cell identity (PCI) list of smtc2 LP, the SMTC period follows smtc2 LP; otherwise, the SMTC period follows SMTC. Where T SI-NR is the time required to receive all relevant system information data from the system information block and RRC delay for an NR cell. Ttarget cell_SMTC_period is the SMTC period of the target cell.
[0403] One goal of network communication is to reduce power consumption. For example, in a radio resource control (RRC) connected mode, network configuration for a user equipment (UE) can use two types of synchronization signal block (SSB) based measurement timing configuration (SMTC) (i.e., smtc1 and smtc2) to configure the UE to perform measurements of network cells in different ways. smtc1 can be a legacy configuration configured to enable the UE to perform cell detection and measurements on a particular frequency layer. The network can use smtc2 in the RRC connected mode to speed up measurements, thereby reducing measurement time and power consumption.
[0404] While smtc2 is used to improve power consumption of a UE in RRC connected mode compared to the legacy smtc1, there is currently no mechanism to use the new smtc to improve power consumption in idle and inactive modes. Embodiments described herein use smtc2 in idle and inactive modes. The described embodiments provide methods to incorporate smtc2 to determine the measurement delay or measurement period in idle and inactive modes. Smtc2 can be used to relax the measurement delay, or in other words, increase the amount of time between when a UE should perform a cell measurement and evaluation. As the measurement period is extended, the UE consumes less power. In addition, the relaxed measurement delay can reduce network power consumption as the reduced measurements from the UE means the network can not transmit measurement signals as frequently.
[0405] For both types of SMTC, embodiments herein describe when a UE should use smtc1 (legacy configuration) and when a UE should use smtc2 (new power saving configuration) to determine the measurement delay or measurement period in idle and inactive modes. More specifically, in some embodiments, smtc2 is smtc2-long period (LP), and embodiments describe UE behavior in idle and inactive modes to accommodate smtc2-lp for measurements.
[0406] In inter-RAT cell reselection, the UE shall listen to the downlink of the serving cell for paging reception until the UE is able to start listening to the downlink channel for paging reception of the target inter-RAT cell. For NR to E-UTRAN cell reselection, the interruption time shall not exceed T SI-EUTRA +T iot-共享 + 55 ms. Where T SI-EUTRA is the time required to receive all relevant system information data from system information blocks and RRC delay for E-UTRAN cell.
[0407] It should be appreciated that in this embodiment, the parameter T iot-共享 may correspond to the second extension factor in the above, or to the extended time Text in FIG. 5.
[0408] In some other embodiments, the UE can include the configuration information of DRX in the sent command (e.g., Qurry) to start the A-IoT device, so that the A-IoT device can determine the timing of performing the IoT UL operation.
[0409] To minimize the impact of the conflict between IoT UL and Uu DL paging / RRM, the following methods can be considered:
[0410] In some embodiments, the IoT UL operation timing overlaps with the PO as much as possible.
[0411] Optionally, the IoT UL operation period is the paging DRX cycle / N, or the paging DRX cycle * M, where N and M are network configured integers. This scheme can allow the UE to sleep more to gain more UE power saving gain.
[0412] In some embodiments, if the UE cannot perform PO monitoring and IoT UL operation at the same time, the UE will perform the IoT UL operation first, and then perform the PO monitoring.
[0413] If the LP-WUS / PEI indicates that there is no paging in this PO, the UE will perform the IoT UL operation; otherwise, if time permits, the UE will first perform the PO monitoring, and then perform the IoT UL operation.
[0414] It should be noted that in the above embodiments, the Uu UE in the RRC idle state or inactive mode acts as an intermediate node in topology 2, that is, the first node in the above.
[0415] In some embodiments, the UE will initiate communication between the UE and the AIoT device.
[0416] In some embodiments, the UE in the idle state receives DL paging and other measurements in the Uu DL carrier, and transmits A-IoT DL commands in the Uu UL carrier. Optionally, these carriers can be different.
[0417] In some embodiments, the AIoT UL response to Uu needs to occur within the DRX duration of the UE (which can be understood as the active period of the DRX cycle in the above).
[0418] In some embodiments, it is allowed to interrupt the UE's paging and / or RRM measurements during the same DRX duration.
[0419] The embodiments of the present disclosure also propose an apparatus for implementing any of the above methods, for example, an apparatus comprising units or modules for implementing the steps performed by the terminal in any of the above methods. For another example, another apparatus is proposed, comprising units or modules for implementing the steps performed by the network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.
