[0001] The present application relates to the field of communication technology, and more specifically, to a wireless communication method and communication device. Background Art

[0002] In some scenarios, the first device can only perform a send or receive operation after collecting a certain amount of energy. Conversely, if the first device does not collect sufficient energy, the first device cannot perform a send or receive operation. However, the traditional downlink control information (DCI) transmission process does not take this scenario into account, which may reduce the possibility of the first device successfully receiving the DCI.

[0004] The present application provides a wireless communication method and a communication device. The following introduces various aspects involved in the present application.

[0005] In a first aspect, a wireless communication method is provided, including: a first device monitors downlink control information DCI based on multiple monitoring opportunities; wherein, a first duration corresponding to the multiple monitoring opportunities is associated with a second duration; and / or a first time interval between a transmission resource scheduled by the DCI and a transmission resource of the DCI is associated with a second duration; wherein, the second duration is associated with a time required for energy collection by the first device.

[0006] In a second aspect, a wireless communication method is provided, including: a second device sends downlink control information DCI to a first device based on multiple monitoring opportunities; wherein, a first duration corresponding to the multiple monitoring opportunities is associated with a second duration; and / or a first time interval between a transmission resource scheduled by the DCI and a transmission resource of the DCI is associated with a second duration; wherein, the second duration is associated with the time required for energy collection by the first device.

[0007] According to a third aspect, a communication device is provided, which is a first device and includes: a processing unit for monitoring downlink control information DCI based on multiple monitoring opportunities; wherein the first duration corresponding to the multiple monitoring opportunities is associated with the second duration; and / or the first time interval between the transmission resources scheduled by the DCI and the transmission resources of the DCI is associated with the second duration; wherein the second duration is associated with the time required for energy collection by the first device.

[0008] In a fourth aspect, a communication device is provided, which is a second device and includes: a sending unit for sending downlink control information DCI to a first device based on multiple monitoring opportunities; wherein the first duration corresponding to the multiple monitoring opportunities is associated with the second duration; and / or the first time interval between the transmission resources scheduled by the DCI and the transmission resources of the DCI is associated with the second duration; wherein the second duration is associated with the time required for the first device to collect energy.

[0009] In a fifth aspect, a communication device is provided, comprising a processor, a memory, and a communication interface, wherein the memory is used to store one or more computer programs, and the processor is used to call the computer program in the memory so that the communication device executes part or all of the steps in the methods of the above aspects.

[0010] In a sixth aspect, an embodiment of the present application provides a communication system, which includes the first device and / or the second device described above. In another possible design, the system may also include other devices that interact with the first device and / or the second device in the solution provided in the embodiment of the present application.

[0011] In the seventh aspect, an embodiment of the present application provides a computer-readable storage medium, which stores a computer program, and the computer program enables a communication device (for example, a first device and / or a second device) to perform some or all of the steps in the methods of the above aspects.

[0012] In an eighth aspect, embodiments of the present application provide a computer program product, wherein the computer program product includes a non-transitory computer-readable storage medium storing a computer program, wherein the computer program is operable to cause a communication device (e.g., a first device and / or a second device) to perform some or all of the steps of the methods described in each of the above aspects.

[0013] In a ninth aspect, an embodiment of the present application provides a chip comprising a memory and a processor, wherein the processor can call and run a computer program from the memory to implement some or all of the steps described in the methods of the above aspects.

[0014] In the embodiment of the present application, by associating the first duration with the second duration corresponding to multiple monitoring opportunities, the first device is facilitated to collect a certain amount of energy within the first duration, and utilize this energy to monitor DCI, thereby increasing the likelihood that the first device will successfully receive DCI. This avoids the situation in conventional solutions where the first device fails to receive DCI due to insufficient energy collection.

[0015] In addition, in some scenarios, since the first device needs to consume energy to monitor DCI, it is possible that when the first device is preparing to perform uplink transmission or downlink reception based on the transmission resources scheduled by DCI, its stored energy is insufficient to support uplink transmission or downlink reception. In this case, before performing uplink transmission or downlink reception, the first device needs to re-collect energy. Therefore, in an embodiment of the present application, setting a first time interval associated with the second duration helps the first device collect a certain amount of energy before performing uplink transmission or downlink reception in order to perform uplink transmission or downlink reception.

[0028] The technical solution in this application will be described below with reference to the accompanying drawings.

[0029] Ambient Internet of Things (A-IoT)

[0030] A-IoT communication utilizes energy harvesting and backscatter communication technologies. A-IoT devices are IoT devices that use various environmental energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy, to power themselves. These devices can have no energy storage capacity or very limited energy storage capacity (e.g., using capacitors with a capacity of tens of microfarads). Compared to traditional Internet of Things (IoT) devices, A-IoT devices offer numerous advantages, including the absence of conventional batteries, maintenance-free operation, compact size, reduced complexity, low cost, and a long lifespan.

[0031] In some scenarios, A-IoT devices can also be called zero-power devices.

[0032] The AIoT can include a network device 110 and an A-IoT device 120, as shown in Figure 1. The network device is used to send wireless power supply signals and downlink communication signals to the A-IoT device and to receive backscattered signals from the A-IoT device. A basic A-IoT device includes an energy harvesting module, a backscatter communication module, and a low-power computing module. Furthermore, the A-IoT device may also include a memory or sensor for storing basic information (such as item identification) or acquiring sensor data such as ambient temperature and humidity.

[0033] It should be noted that Figure 1 exemplarily shows a network device and an A-IoT device. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of A-IoT devices within its coverage area. This embodiment of the present application does not limit this.

[0034] In addition, in some implementations, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0035] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), cellular Internet of Things, etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, etc.

[0036] The A-IoT device in the embodiment of the present application can be used as a terminal device, which can also be called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal device, wireless communication device, user agent or user device. The terminal device in the embodiment of the present application can be a device that provides voice and / or data connectivity to the user, which can be used to connect people, objects and machines, such as household appliances, sensors, electronic tags, etc. with wireless connection functions. The terminal in the embodiment of the present application can be a wireless terminal in a smart home, a wireless terminal in an IWSN, a wireless terminal in smart logistics and smart warehousing, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, etc.

[0037] The network device in the embodiment of the present application may be a device for communicating with a terminal device. If the terminal is an electronic tag, the network device may be a reader / writer for reading and writing the electronic tag (for example, a reader / writer based on radio frequency identification (RFID) technology). The network device may also be an access network device or a wireless access network device, such as a base station. The network device in the embodiment of the present application may refer to a radio access network (RAN) node (or device) that connects the terminal device to a wireless network. A base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. A base station can also refer to a communication module, modem or chip used to be set in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form used by the network equipment.

[0038] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0039] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0040] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0041] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0042] In some implementations, the terminal 120 may include an energy collection module 121 and a backscatter communication module 122. The energy collection module 121 and the backscatter communication module 122 will be introduced below in conjunction with Figures 2 to 4. For the sake of brevity, they will not be repeated here. In some cases, the terminal 120 may also include a low-power computing module 123. The low-power computing module 123 is used to provide computing functions for the terminal, such as data processing. In other cases, the terminal 120 may also include a sensor 124 for collecting external information (for example, ambient temperature, ambient humidity, etc.). In other cases, the terminal 120 may also include a memory 125 for storing some information (for example, external information collected by the above-mentioned sensors, or such as item identification, etc.).

[0043] The energy harvesting module 121 is used to harvest energy. In some implementations, energy can be harvested via a wireless power supply signal transmitted by a network device. The wireless power supply signal can be a "radio frequency signal" transmitted by the network device. Therefore, the energy harvesting module is also referred to as a "radio frequency energy harvesting module."

[0044] FIG2 shows a possible structure of an energy collection module. As shown in FIG2 , the energy collection module 121 can collect the energy of the spatial electromagnetic waves of the radio frequency signal based on the principle of electromagnetic induction, and store the collected energy in the capacitor C, which is the charging process of the capacitor C. When the charging process of the capacitor C is completed, the capacitor C can start to discharge to provide energy for the terminal operation. For example, the discharge of the capacitor C can be used to drive the terminal to perform low-power demodulation of the data sent by the network device. For another example, the discharge of the capacitor C can be used to drive the terminal to modulate the data to be sent. For another example, the discharge of the capacitor C can be used to drive the sensor of the terminal to collect data. For another example, the discharge of the capacitor C can be used to drive the terminal to read the data in the memory 125, etc.

[0045] The backscatter communication module 122 is used for backscattering communication between the terminal and the network device. The principle of backscattering communication in an embodiment of the present application is described below in conjunction with FIG3 . Referring to FIG3 , the terminal 120 receives a wireless signal transmitted by the network device 110 and modulates the wireless signal to carry the information to be transmitted. Finally, the modulated signal is radiated from the antenna. This information transmission process is called backscattering communication. Backscattering communication and load modulation are closely related. Load modulation adjusts and controls the circuit parameters of the terminal's oscillating circuit according to the data stream's rhythm, causing parameters such as the terminal impedance to change accordingly, thereby completing the modulation process. Load modulation techniques mainly include resistive load modulation and capacitive load modulation. In resistive load modulation, a resistor is connected in parallel to the load, and the resistor is turned on or off based on the control of the binary data stream, as shown in FIG4 below. The switching of the resistor causes a change in the circuit voltage, thereby implementing amplitude-shift keying (ASK) modulation, which modulates and transmits the signal by adjusting the amplitude of the terminal's backscattered signal. Similarly, in capacitive load modulation, the resonant frequency of the circuit can be changed by switching the capacitor on and off, realizing frequency-shift keying (FSK) modulation, that is, signal modulation and transmission are achieved by adjusting the operating frequency of the terminal's backscattered signal.

[0046] In some implementations, the transmit (transmit, TX) path of the network device 110 may be further provided with other devices for processing the transmitted signal, such as an amplifier (AMP). The receive (receive, RX) path of the network device 110 may also be provided with other devices for processing the received signal, such as a low noise amplifier (LNA).

[0047] In other implementations, the terminal 120 may be provided with an energy collection unit for collecting energy from the wireless power supply signal sent by the network device. Of course, the terminal 120 may also be provided with a logic processing unit to perform corresponding calculation functions.

[0048] It should be noted that, whether it is the network device 110 or the terminal 120, Figure 3 only shows the connection structure of the signal processing circuit as an example. The processing circuit of the network device 110 and / or the terminal 120 may include other components, and the embodiments of the present application do not specifically limit this.

[0049] Typically, load modulation can be achieved through resistive load modulation and capacitive load modulation. Figure 4 shows a circuit diagram of a terminal based on resistive load modulation technology. It should be noted that the circuit shown in Figure 4 implements load modulation technology in a manner similar to existing circuits implementing load modulation technology. For the sake of brevity, the functions of resistors R2 and R3, capacitors C1 and C2, and inductors L1 and L2 shown in Figure 4 are not further described.

[0050] In resistive load modulation, a resistor R can be connected in parallel with the load. L The switch S can be controlled based on the binary data flow to realize the resistor R L In this way, the resistor R L The on-off of the switch will cause the circuit voltage to change, and the change of the circuit voltage can control the amplitude of the backscattered signal of the terminal, thereby realizing the modulation of the backscattered signal, that is, ASK modulation of the backscattered signal.

[0051] Similarly, in capacitive load modulation, the on-off switching of the capacitor can be controlled based on a binary data stream to change the circuit resonant frequency, thereby changing the operating frequency of the backscattered signal to achieve FSK modulation.

[0052] As mentioned above, terminals can use load modulation to modulate incoming signals (i.e., signals sent by network devices) to achieve backscatter communication. Therefore, terminals in backscatter communication generally have the following advantages.

[0053] Advantage 1: Since the terminal does not need to actively transmit signals, there is no need to construct a complex RF path. For example, components such as power amplifiers (PAs) and RF filters can be omitted in the RF path, reducing the cost and size of the terminal.

[0054] The second advantage is that since the terminal does not need to actively generate high-frequency signals, a high-frequency crystal oscillator is not required, thereby reducing the cost and size of the terminal.

[0055] Advantage three: Since the terminal can use backscatter technology to communicate with network equipment, the terminal consumes less energy during communication and does not even need to consume its own energy.

[0056] Classification of A-IoT devices

[0057] In some scenarios, A-IoT devices can be divided into three categories based on their energy sources and energy usage: passive A-IoT devices, semi-passive A-IoT devices, and active A-IoT devices.

[0058] 1. Passive A-IoT devices

[0059] Passive A-IoT devices generally do not require built-in batteries. When an A-IoT device is close to a network device, the A-IoT device is within the near field formed by the radiation of the network device's antenna. At this time, the antenna of the A-IoT device can generate an induced current through electromagnetic induction. The induced current can power the A-IoT device to achieve demodulation of the received signal and / or modulation and encoding of the transmitted signal. In some implementations, the above-mentioned passive A-IoT device can be an electronic tag, and accordingly, the network device can be a reader / writer of a (radio frequency identification, RFID) system, which is used to read the content in the electronic tag and / or to change the content in the electronic tag.

[0060] 2. Semi-passive A-IoT devices

[0061] Semi-passive A-IoT devices don't have conventional batteries themselves, but instead use an energy harvesting module 121 to harvest radio wave energy and store it in an energy storage unit (e.g., a capacitor). This energy storage unit then powers the A-IoT device to demodulate received signals and / or modulate and encode transmitted signals.

[0062] Active A-IoT devices

[0063] Active A-IoT devices can have built-in batteries. These batteries power the A-IoT device to demodulate received signals and / or modulate and encode transmitted signals. However, when the A-IoT device communicates using backscatter technology, it does not consume battery power. Therefore, for such A-IoT devices, "zero power consumption" is primarily achieved when the terminal uses backscatter technology for communication.

[0064] In some implementations, the active A-IoT device can be an electronic tag, and the network device can be an RFID reader. In this case, the internal battery can power the RFID chip in the A-IoT device, increasing the read / write distance between the RFID reader and the electronic tag. Furthermore, the internal battery can power the RFID chip in the A-IoT device, shortening the latency between the RFID reader and the electronic tag, thereby improving communication reliability.

[0065] For the passive and semi-passive A-IoT devices mentioned above, since they do not have built-in batteries, they need to harvest energy from the environment (power harvesting). On the one hand, the A-IoT device can only drive the circuit to receive or transmit data when the ambient energy it collects reaches a certain amount. Before the A-IoT device collects enough energy, it cannot receive or transmit data. On the other hand, when the A-IoT device receives or transmits data, it consumes stored energy. When the stored energy falls below a certain amount, the A-IoT device can no longer receive or transmit data. At this point, the A-IoT device needs to continue harvesting energy from the environment in order to continue receiving or transmitting data. As shown in Figure 5, the A-IoT device first harvests energy. At time t1, when the collected energy exceeds the energy threshold, the A-IoT device can receive or transmit data. Accordingly, when the A-IoT device performs data reception, it consumes energy, resulting in a decrease in the energy stored in the A-IoT device. If the stored energy is lower than the energy threshold, the A-IoT device cannot receive or send data and needs to continue energy collection. When the collected energy exceeds the energy threshold again (for example, at time t2), the A-IoT device can continue to send data.

[0066] In other scenarios, A-IoT devices can be divided into three categories based on transmitter type, including the following types: A-IoT devices based on backscattering, A-IoT devices based on active transmitters, and A-IoT devices with both backscattering and active transmitters.

[0067] 1) Backscatter-based A-IoT devices.

[0068] These A-IoT devices use the aforementioned backscattering method to transmit uplink data. These devices lack active transmitters, only backscattering transmitters. Therefore, when these devices transmit data, they require network equipment to provide a carrier, which they then use to perform backscattering to achieve data transmission.

[0069] 2) A-IoT devices based on active transmitters.

[0070] These A-IoT devices use active transmitters with active transmission capabilities for uplink data transmission. Therefore, when sending data, these A-IoT devices can use their own active transmitters to send data without the need for network equipment to provide a carrier. Examples of active transmitters suitable for A-IoT devices include ultra-low-power ASK and FSK transmitters. Based on current implementations, these transmitters can reduce overall power consumption to 400-600uW when transmitting a 100uW signal.

[0071] 3) A-IoT devices with both backscatter and active transmitters.

[0072] This type of terminal supports both backscatter and active transmitters. The terminal can determine which uplink signal transmission method to use: backscatter or active transmitter, based on various conditions (such as battery life and available ambient energy) or based on network device scheduling.

[0073] Low-power IoT based on cellular networks

[0074] The cellular Internet of Things (IoT) is booming. 3GPP has standardized IoT technologies such as narrowband IoT (NB-IoT), machine-type communication (MTC), and reduced capability (RedCap). However, there are still many scenarios where IoT communication needs cannot be met using existing technologies. These include harsh communication environments (high temperature, low temperature, high humidity, high voltage, high radiation, or high-speed movement), the need for extremely small terminal form factors, and extremely low costs.

[0075] Therefore, in order to cover these unmet IoT communication needs, cellular networks also need to develop ultra-low-cost, extremely small-size, battery-free / maintenance-free IoT, and environmental IoT can just meet this need.

[0076] Based on the discussion of A-IoT application scenarios in 3GPP system architecture (SA)1, A-IoT can be used in at least the following four scenarios:

[0077] Object recognition, such as logistics, production line product management, and supply chain management.

[0078] Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment.

[0079] Positioning, such as indoor positioning, intelligent object search, and production line item positioning.

[0080] Intelligent control, such as intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation and fertilization).

[0081] In a low-power IoT based on a cellular network, an A-IoT device can directly transmit and receive carriers, data, or signals from a base station, and send or backscatter data or channels to the base station, as shown in Figure 6 (represented as the first topology). Alternatively, communication between the A-IoT and the base station can be achieved through an intermediate node. In this case, the intermediate node sends a carrier, data, or signal to the A-IoT device, the A-IoT device sends or backscatters data or signals to the intermediate node, and the intermediate node sends the received data or signal to the base station, as shown in Figure 7 (represented as the second topology).

[0082] In the embodiments of the present application, the intermediate node is not limited. In some implementations, the intermediate node may be a terminal device. In other implementations, the intermediate node may be a network device. In other implementations, the intermediate node may be an integrated access and backhaul (IAB) node.

[0083] In some scenarios, the control information sent to A-IoT devices can be called DCI. In other scenarios, the above control information can also be called forward link control information (FCI) or access link downlink control information (access link control information). Of course, the control information can also be called A-IoT link control information (ACI). For ease of description, the following uses DCI as an example.

[0084] In an embodiment of the present application, the sending end of sending the above-mentioned control information is a network device or an intermediate node.

[0085] In some scenarios, the first device must collect a certain amount of energy before it can perform a transmission or reception operation. Conversely, if the first device does not collect sufficient energy, the first device cannot perform a transmission or reception operation. However, the traditional DCI transmission process does not take this scenario into account, which may reduce the possibility of the first device successfully receiving the DCI.

[0086] For example, in the Ambient IoT, the first device is the A-IoT device described above. Accordingly, the A-IoT device can only transmit or receive after collecting a certain amount of energy. Conversely, if the A-IoT device does not collect enough energy, it cannot transmit or receive. However, the traditional DCI transmission process does not consider this scenario, which may reduce the likelihood of the A-IoT device successfully receiving DCI.

[0087] Therefore, to address the above issues, an embodiment of the present application provides a wireless communication method that helps increase the possibility of a first device successfully receiving DCI. The wireless communication method of an embodiment of the present application is described below with reference to FIG8 . The method shown in FIG8 includes step S810 .

[0088] In step S810 , the second device sends DCI to the first device based on multiple monitoring occasions. Correspondingly, the first device monitors the DCI based on the multiple monitoring occasions.

[0089] In the embodiment of the present application, the above-mentioned multiple monitoring opportunities may be referred to as a group of monitoring opportunities or a monitoring opportunity group, or in other words, a group of monitoring opportunities or a monitoring opportunity group may include the above-mentioned multiple monitoring opportunities.

[0090] In an embodiment of the present application, the terminal device may be configured with multiple groups of monitoring opportunities or multiple monitoring opportunity groups.

[0091] In the embodiment of the present application, multiple monitoring opportunities refer to multiple DCI monitoring opportunities. Unless otherwise specified, the monitoring opportunities in the embodiment of the present application refer to DCI monitoring opportunities.

[0092] In some implementations, the DCI may be carried via a first channel, where the first channel may be, for example, a physical downlink control channel (PDCCH).

[0093] In some implementations, the first device may be the A-IoT device described above.

[0094] In some implementations, the second device may be the network device described above. For example, in the topology shown in FIG6 , the network device may send DCI directly to the A-IoT device. In other implementations, the second device may be the intermediate node described above. For example, in the topology shown in FIG7 , the network device may send DCI to the A-IoT device via the intermediate node. In other words, the DCI transmitted in step S810 may be determined based on the DCI sent by the network device to the intermediate node.

[0095] In the embodiments of the present application, the method for determining DCI is not limited. Assuming that the DCI sent by the intermediate node to the first device is called DCI#1, and the DCI sent by the network device to the intermediate node is called DCI#2, then DCI#1 can be the same as DCI#2, or the information in DCI#1 is determined based on the information in DCI#2, or DCI#1 is obtained by processing DCI#2, where the processing may include, for example, decapsulation, format conversion, etc.

[0096] The first and second devices of the embodiments of the present application are described above. The following describes multiple monitoring opportunities in the embodiments of the present application in conjunction with Example 1. In some scenarios, the aforementioned monitoring opportunities may also be referred to as "transmission opportunities" or DCI monitoring opportunities. In other scenarios, the first device monitoring DCI may be replaced by the first device detecting DCI; therefore, the monitoring opportunities may also be referred to as detection opportunities.

[0097] Example 1: Multiple Monitoring Opportunities

[0098] In some implementations, the first duration corresponding to multiple monitoring opportunities is associated with a second duration, wherein the second duration is associated with the time required for the first device to collect energy, or in other words, the second duration is determined based on the time required for the first device to collect energy.

[0099] In some implementations, the first duration can be understood as a time range that includes multiple monitoring opportunities. In some implementations, the first duration is determined based on the durations corresponding to multiple monitoring opportunities. For example, the start time of the first duration can be determined based on the start time of the earliest monitoring opportunity among multiple monitoring opportunities, wherein the start time of the first duration is the start time of the earliest monitoring opportunity among multiple monitoring opportunities (see Figure 10 below), or the start time of the first duration can be earlier than the start time of the earliest monitoring opportunity among multiple monitoring opportunities. For another example, the end time of the first duration can be determined based on the end time of the latest monitoring opportunity among multiple monitoring opportunities, wherein the end time of the first duration is the end time of the latest monitoring opportunity among multiple monitoring opportunities, or the end time of the first duration can be later than the end time of the latest monitoring opportunity among multiple monitoring opportunities (see Figure 10 below). Of course, in an embodiment of the present application, the end time of the first time period can also be determined based on the start time of the latest monitoring opportunity among multiple monitoring opportunities, wherein the end time of the first time period is the start time of the latest monitoring opportunity among multiple monitoring opportunities (see Figure 11 below), or the end time of the first time period can be later than the start time of the latest monitoring opportunity among multiple monitoring opportunities.

[0100] In some implementations, the association between the first duration and the second duration can be understood as the determination of the first duration based on the second duration. For example, the first duration can be equal to the second duration. For another example, the first duration can be a period of time greater than or equal to the second duration. For another example, the first duration can be a period of time greater than or equal to the second duration.

[0101] In the embodiment of the present application, by setting the first duration corresponding to multiple monitoring opportunities to be associated with the second duration (or, setting the first duration corresponding to multiple monitoring opportunities based on the second duration), it is helpful for the first device to collect a certain amount of energy within the first duration, so as to use this energy to monitor DCI, thereby increasing the possibility of the first device successfully receiving DCI. This avoids the situation in traditional solutions where the first device fails to receive DCI due to insufficient energy collection.

[0102] In some implementations, the time domain position of the first time length can be determined based on the first time domain position, wherein the first time domain position is associated with one or more of the following: the time domain position corresponding to a synchronization signal (SS); the time domain position of a channel carrying broadcast information; the time domain position of a channel carrying a master information block (MIB); and the time domain position of a channel carrying a system information block (SIB).

[0103] Taking the association of the first time domain position with the time domain position corresponding to the SS as an example, in some implementations, the first time domain position may be the starting position or the ending position of the time domain position corresponding to the SS. Of course, in the embodiment of the present application, the first time domain position may be determined by offsetting the starting position or the ending position of the time domain position corresponding to the SS by a time domain offset value, where the time domain offset value may be predefined, preconfigured, or configured by a network device.

[0104] In some implementations, the time domain location corresponding to the SS may include the time domain location of a transmission resource of the SS, or the time domain location of a monitoring opportunity for monitoring the SS.

[0105] Taking the association of the first time domain position with the time domain position of the channel carrying the broadcast information as an example, in some implementations, the first time domain position may be the starting position or the ending position of the time domain position of the channel carrying the broadcast information. Of course, in the embodiments of the present application, the first time domain position may be determined by offsetting the starting position or the ending position of the time domain position of the channel carrying the broadcast information by a time domain offset value, where the time domain offset value may be predefined, preconfigured, or configured by a network device.

[0106] Taking the association of the first time domain position with the time domain position of the channel carrying the MIB as an example, in some implementations, the first time domain position may be the starting position or the ending position of the time domain position of the channel carrying the MIB. Of course, in the embodiment of the present application, the first time domain position may be determined by offsetting the starting position or the ending position of the time domain position of the channel carrying the MIB by a time domain offset value, wherein the time domain offset value may be predefined, preconfigured, or configured by a network device.

[0107] Taking the association of the first time domain position with the time domain position of the channel carrying the SIB as an example, in some implementations, the first time domain position may be the starting position or the ending position of the time domain position of the channel carrying the SIB. Of course, in the embodiment of the present application, the first time domain position may be determined by offsetting the starting position or the ending position of the time domain position of the channel carrying the SIB as the initial position by a time domain offset value, wherein the time domain offset value may be predefined, preconfigured, or configured by a network device.

[0108] In the embodiment of the present application, there is no limitation on the manner in which the time domain position of the first duration is determined based on the first time domain position. For example, the time domain position of the first duration may be determined by taking the first time domain position as the initial position and offsetting the time domain offset value, wherein the time domain offset value may be predefined, preconfigured, or configured by a network device. In other words, the time domain position of the first duration may be separated from the first time domain position by a time interval (for example, the time interval T3 described below in conjunction with FIG. 11 ). In addition, the time domain position of the first duration may be, for example, the starting position or the ending position of the first duration.

[0109] In some scenarios, multiple monitoring opportunities corresponding to the first time length belong to the first group of monitoring opportunities among multiple groups of monitoring opportunities, wherein the time domain position of the first time length corresponding to the first group of monitoring opportunities is determined based on the first time domain position, or, in other words, only the time domain position of the first time length corresponding to the first group of monitoring opportunities among the multiple groups of monitoring opportunities is determined based on the first time domain position, wherein the first group of monitoring opportunities can be the group of monitoring opportunities with the earliest time domain position among the multiple groups of monitoring opportunities.

[0110] In an embodiment of the present application, there is no limitation on the method of determining the time domain position of the first time length corresponding to other groups of monitoring opportunities. In some implementations, the time domain position of the first time length corresponding to other groups of monitoring opportunities can be determined based on the time domain position of the first time length corresponding to the first group of monitoring opportunities. For example, when multiple groups of monitoring opportunities are periodic and the period value is P2, the time domain position of the first time length corresponding to other groups of monitoring opportunities can be determined based on the time domain position of the first time length corresponding to the first group of monitoring opportunities and P2. For another example, the time domain position of the first time length corresponding to other groups of monitoring opportunities can be determined based on the time domain position of the first time length corresponding to the first group of monitoring opportunities and time interval 1, wherein time interval 1 is the time interval between two adjacent groups of monitoring opportunities in multiple groups of monitoring opportunities. Among them, the time domain position of the first time length can be, for example, the starting position or the ending position of the first time length.

[0111] For example, if the first time domain position is the time domain starting position corresponding to the SS, and the transmission period of the SS is the same as the period of multiple groups of monitoring opportunities, then the first duration corresponding to each group of monitoring opportunities in the multiple groups of monitoring opportunities can be determined based on the time domain starting position of the SS. This will be described below in conjunction with Figure 11.

[0112] Of course, in the embodiment of the present application, the time domain position of the first duration corresponding to each of the other groups of monitoring opportunities in the multiple groups of monitoring opportunities can be determined based on the first time domain position. For example, the time domain position of the first duration corresponding to each group of monitoring opportunities can be determined based on the first time domain position and the corresponding time interval 2, where time interval 2 includes the time interval between the first time domain position and each of the other groups of monitoring opportunities.

[0113] The above introduces the first duration in the embodiment of the present application, and the following introduces the first time interval between the DCI-scheduled transmission resources and the DCI transmission resources in the embodiment of the present application.

[0114] In some implementations, a first time interval between a DCI-scheduled transmission resource and a DCI transmission resource is associated with a second duration.

[0115] In the embodiment of the present application, the implementation method of the first time interval is not limited. For example, the first time interval can be the time interval between the time domain starting position of the transmission resource scheduled by the DCI and the time domain starting position of the transmission resource of the DCI. This will be introduced below in conjunction with Figure 10. For another example, the first time interval can be the time domain ending position of the transmission resource scheduled by the DCI and the time domain starting position of the transmission resource of the DCI. For another example, the first time interval can be the time domain ending position of the transmission resource scheduled by the DCI and the time domain ending position of the transmission resource of the DCI. For another example, the first time interval can be the time domain starting position of the transmission resource scheduled by the DCI and the time domain starting position of the transmission resource of the DCI.

[0116] In some implementations, the first time interval is associated with the second duration, which can be understood as the first time interval being determined based on the second duration. For example, the first time interval can be equal to the second duration. For another example, the first time interval can be a period of time greater than or equal to the second duration. For another example, the first time interval can be a period of time greater than or equal to the second duration.

[0117] In some implementations, the transmission resources scheduled by the DCI may include transmission resource 1 for downlink transmission and / or transmission resource 2 for uplink transmission. Downlink transmission may include a network device sending data or information to a first device or an intermediate node, or an intermediate node sending data or information to the first device. Uplink transmission may include the first device sending data or information to a network device or an intermediate node.

[0118] In the embodiments of the present application, there is no limitation on the transmission resources. In some implementations, the transmission resources may include one or more of time domain resources, frequency domain resources, and code domain resources.

[0119] In some scenarios, since the first device consumes energy to monitor DCI, it is possible that when the first device is preparing to perform uplink transmission or downlink reception based on the transmission resources scheduled by the DCI, its stored energy is insufficient to support the uplink transmission or downlink reception. In this case, before performing the uplink transmission or downlink reception, the first device needs to re-collect energy. Therefore, in an embodiment of the present application, determining the first time interval based on the second duration helps the first device collect a certain amount of energy before performing the uplink transmission or downlink reception in order to perform the uplink transmission or downlink reception.

[0120] The second duration is introduced above when introducing the first time interval and the first duration. In the embodiment of the present application, the second duration is not specifically limited. In some implementations, the second duration is determined based on the maximum duration required for the first device to collect energy exceeding the energy threshold. For example, the second duration is greater than or equal to the maximum duration required for the first device to collect energy exceeding the energy threshold. For another example, the second duration is equal to the maximum duration required for the first device to collect energy exceeding the energy threshold. For another example, the second duration is greater than the maximum duration required for the first device to collect energy exceeding the energy threshold.

[0121] In the embodiments of the present application, the maximum duration is not limited. For example, the maximum duration may refer to the time from the moment when the first device has no stored energy (or the stored energy is 0) until the energy stored in the first device is equal to the energy threshold. For another example, the maximum duration may refer to the time from the moment when the first device has no stored energy until the energy stored in the first device is greater than or equal to the energy threshold. For another example, the maximum duration may refer to the time from the moment when the first device has no stored energy until the energy stored in the first device is greater than the energy threshold.

[0122] In the embodiments of the present application, there is no limitation on the method for determining the energy threshold. For example, the energy threshold may be determined based on a protocol definition, or based on network configuration information, or based on terminal capabilities.

[0123] In other implementations, the second duration is determined based on a minimum duration required for the first device to collect energy exceeding the energy threshold. In the embodiments of the present application, the minimum duration is not limited. For example, the minimum duration may refer to the duration from the moment when the first device has no stored energy (or the stored energy is 0) until the energy stored by the first device equals or exceeds the energy threshold.

[0124] In some other implementations, the second duration is associated with the capability of the first device, and the capability of the first device is associated with the time required for the first device to harvest energy.

[0125] In some implementations, the capability of the first device is used to indicate the duration required for the first device to collect energy, or in other words, the capability of the first device includes the duration required for the first device to collect energy. For example, the higher the capability of the first device, the shorter the duration required for the first device to collect energy. Conversely, the lower the capability of the first device, the longer the duration required for the first device to collect energy. For another example, two different capabilities can be pre-defined, each corresponding to a different duration for energy collection, wherein the duration for energy collection corresponding to the first type of capability is 1 millisecond, and the duration for energy collection corresponding to the second type of capability is 3 milliseconds.

[0126] In some implementations, the first device may indicate the capabilities of the first device to the second device so that the second device determines the second duration based on the capabilities of the first device.

[0127] In some scenarios, the capability of the first device may be referred to as a terminal capability (UE capability).

[0128] In some implementations, the DCI corresponding to multiple monitoring opportunities is used to schedule the same transmission resources, or in other words, the DCI transmitted in multiple monitoring opportunities instructs the first device to perform downlink reception or uplink transmission on the same transmission resources, which helps to increase the possibility of the first device successfully receiving the DCI. This will be described below in conjunction with Figure 9. Of course, in an embodiment of the present application, the DCI corresponding to multiple monitoring opportunities can be used to schedule different transmission resources, or in other words, the DCI transmitted in multiple monitoring opportunities instructs the first device to perform downlink reception or uplink transmission on different transmission resources.

[0129] In the embodiments of the present application, there is no limitation on the different multiple transmission resources. In some implementations, the relative time domain positions of the transmission resources scheduled by the DCI transmitted in multiple monitoring opportunities and the DCI transmission resources are the same, as will be described below in conjunction with FIG12. In other implementations, the relative time domain positions of the transmission resources scheduled by the DCI transmitted in multiple monitoring opportunities and the DCI transmission resources are different, as will be described below in conjunction with FIG13.

[0130] In some implementations, the multiple monitoring opportunities are periodically arranged in the time domain, or in other words, the multiple monitoring opportunities are periodic. This will be described below in conjunction with Figure 10. Of course, in the embodiment of the present application, the multiple monitoring opportunities may not be periodic.

[0131] In some implementations, multiple monitoring opportunities belong to one group of monitoring opportunities in multiple groups of monitoring opportunities, and the multiple groups of monitoring opportunities are periodically arranged in the time domain, or there is periodicity between the multiple groups of monitoring opportunities, or there is the same time interval between two adjacent groups of monitoring opportunities in the time domain in the multiple groups of monitoring opportunities, or there is the same time interval between two adjacent groups of monitoring opportunities in the time domain in the multiple groups of monitoring opportunities, or there is the same time interval between two adjacent groups of monitoring opportunities in the time domain in the multiple groups of monitoring opportunities, and so on. This will be described below in conjunction with FIG10. Of course, in the embodiments of the present application, there may not be periodicity between the multiple groups of monitoring opportunities.

[0132] For ease of understanding, the following describes multiple monitoring opportunities in the embodiments of the present application in conjunction with Figures 9 to 13. It should be understood that for ease of description, the time domain location corresponding to the SS is replaced with the "time domain location of the SS transmission resource" when introducing multiple monitoring opportunities.

[0133] As shown in Figure 9, it is assumed that the time domain includes monitoring opportunity group 1 and monitoring opportunity group 2. Each monitoring opportunity group includes multiple DCI monitoring opportunities, and monitoring opportunity group 1 and monitoring opportunity group 2 each include four DCI monitoring opportunities. Monitoring opportunity group 1 is associated with SS transmission resource 1, and the four DCI1s transmitted in monitoring opportunity group 1 are used to schedule transmission resource 1. Monitoring opportunity group 2 is associated with SS transmission resource 2, and the four DCI2s transmitted in monitoring opportunity group 2 are used to schedule transmission resource 2.

[0134] Accordingly, if the first device detects any DCI1 in the first group of monitoring opportunities (i.e., monitoring opportunity group 1), the first device can perform uplink transmission or downlink reception on transmission resource 1 based on the scheduling of DCI1. If the first device detects any DCI2 in the second group of monitoring opportunities (i.e., monitoring opportunity group 2), the first device can perform uplink transmission or downlink reception on transmission resource 2 based on the scheduling of DCI2.

[0135] As shown in Figure 10, it is assumed that the second time duration required for the first device to reach the energy threshold from no energy to the collected energy is T2, the first time domain position is the time domain position of the SS transmission resource, and the time domain starting position of monitoring opportunity group 1 is separated by a time interval of T3. The first time durations corresponding to monitoring opportunity group 1 and monitoring opportunity group 2 are both T1. Each monitoring opportunity group includes multiple DCI monitoring opportunities. Monitoring opportunity group 1 and monitoring opportunity group 2 each include 4 DCI monitoring opportunities. The period value (or time interval) between two adjacent monitoring opportunities in each monitoring opportunity group is P1. The four DCIs transmitted in monitoring opportunity group 1 are all used to schedule transmission resource 1, wherein the time interval between the time domain starting position of the last monitoring opportunity in monitoring opportunity group 1 and the time domain starting position of transmission resource 1 is time interval T4. The four DCIs transmitted in monitoring opportunity group 2 are all used to schedule transmission resource 2, wherein the time domain starting position of the last monitoring opportunity in monitoring opportunity group 2 and the time domain starting position of transmission resource 2 is time interval T4. In addition, there is a periodicity between the monitoring opportunity groups, and the period is P2, that is, the time interval between the monitoring opportunity group 1 and the monitoring opportunity group 2 is P2.

[0136] In some implementations, the first duration T1 is greater than or equal to (or greater than or equal to) the duration corresponding to (N-1)*P1, and the first duration T1 is greater than or equal to (or greater than or equal to) the second duration T2, so that the first device can collect sufficient energy for DCI monitoring within T1. The value of N is determined based on the number of monitoring opportunities included in a set of monitoring opportunities. For example, the value of N is equal to the number of monitoring opportunities included in a set of monitoring opportunities. P1 represents the time interval between two adjacent monitoring opportunities in a set of monitoring opportunities.

[0137] In some implementations, the time interval T4 is greater than or equal to (or greater than or equal to) the second duration T2, which helps the first device collect sufficient energy after monitoring the DCI and before performing uplink transmission (or downlink reception) based on the transmission resources scheduled by the DCI.

[0138] In some implementations, the starting position of the first duration T1 of monitoring opportunity group 1 can be determined based on the starting position of the SS transmission resource (as an example of the first time domain position) and time interval T3. Correspondingly, the starting position of the first duration T1 of monitoring opportunity group 2 can be determined based on period P2 and the time domain starting position of the first duration corresponding to monitoring opportunity group 1.

[0139] As shown in Figure 11, assume that the second duration required for the first device to reach the energy threshold from zero energy is T2, the SS period and the monitoring opportunity group period are both P2, and the time interval between the time domain position of the monitoring opportunity group and the corresponding SS transmission resource is T3. The first durations corresponding to monitoring opportunity groups 1-4 are all T1. Each monitoring opportunity group includes four DCI monitoring opportunities, and the period value (or time interval) between two adjacent DCI monitoring opportunities in each monitoring opportunity group is P1.

[0140] In some implementations, the first duration T1 is greater than or equal to (or greater than or equal to) the duration corresponding to (N-1)*P1, or the first duration T1 is equal to the duration corresponding to ((N-1)*P1+M). And the first duration T1 is greater than or equal to (or greater than or equal to) the second duration T2, so that the first device can collect sufficient energy for DCI monitoring within T1. Wherein, N is equal to the number of monitoring opportunities included in a set of monitoring opportunities, and M is determined based on the duration corresponding to one monitoring opportunity. For example, P1 takes a value of 28 time domain symbols, M takes a value of 2 time domain symbols, N=4, then T1=(4-1)*28+2=86 time domain symbols.

[0141] In some implementations, the first device may monitor DCI or SS (or DCI and SS) based on the harvested energy.

[0142] In some implementations, the starting position of the first duration T1 corresponding to each group of monitoring opportunities can be determined based on the time domain position of the corresponding SS transmission resource. Referring to Figure 11, the time interval between the time domain starting position of the first duration T1 of monitoring opportunity group 1 and the time domain starting position of the corresponding SS transmission resource (i.e., the first SS transmission resource) is T3. The time interval between the time domain starting position of the first duration T1 of monitoring opportunity group 2 and the time domain starting position of the corresponding SS transmission resource (i.e., the second SS transmission resource) is T3. The time interval between the time domain starting position of the first duration T1 of monitoring opportunity group 3 and the time domain starting position of the corresponding SS transmission resource (i.e., the third SS transmission resource) is T3. The time interval between the time domain starting position of the first duration T1 of monitoring opportunity group 4 and the time domain starting position of the corresponding SS transmission resource (i.e., the fourth SS transmission resource) is T3.

[0143] As shown in Figure 12 , monitoring opportunity group 1 is associated with SS transmission resource 1 and includes four DCI monitoring opportunities. The DCI transmitted in the four DCI monitoring opportunities is used to schedule transmission resources in transmission resource group 1. The DCI transmitted in each DCI monitoring opportunity schedules one transmission resource in transmission resource group 1, and the transmission resources in transmission resource group 1 are used for uplink transmission. Correspondingly, monitoring opportunity group 2 is associated with SS transmission resource 2 and includes four DCI monitoring opportunities. The DCI transmitted in the four DCI monitoring opportunities is used to schedule transmission resources in transmission resource group 2. The DCI transmitted in each DCI monitoring opportunity schedules one transmission resource in transmission resource group 2, and the transmission resources in transmission resource group 2 are used for downlink reception.

[0144] In some implementations, if the first device detects a DCI in monitoring opportunity group 1, it can determine the transmission resources in transmission resource group 1 scheduled by the DCI, and perform uplink transmission on the transmission resources in transmission resource group 1. If the first device detects a DCI in monitoring opportunity group 2, it can determine the transmission resources in transmission resource group 2 scheduled by the DCI, and perform downlink reception on the transmission resources in transmission resource group 2.

[0145] In some implementations, within a set of monitoring opportunities, the relative time-domain positions of the transmission resources scheduled by the DCI and the DCI transmission resources are the same. However, because the time-domain positions of the DCI transmission resources are different, the transmission resources scheduled by the DCIs within the set of monitoring opportunities are also different. For example, in FIG12 , the transmission resources in transmission resource group 1 correspond to different time-domain resources.

[0146] As shown in Figure 13 , monitoring opportunity group 1 is associated with SS transmission resource 1 and includes four DCI monitoring opportunities. The DCI transmitted in the four DCI monitoring opportunities is used to schedule transmission resources in transmission resource group 1. The DCI transmitted in each DCI monitoring opportunity schedules one transmission resource in transmission resource group 1, and the transmission resources in transmission resource group 1 are used for uplink transmission. Correspondingly, monitoring opportunity group 2 is associated with SS transmission resource 2 and includes four DCI monitoring opportunities. The DCI transmitted in the four DCI monitoring opportunities is used to schedule transmission resources in transmission resource group 2. The DCI transmitted in each DCI monitoring opportunity schedules one transmission resource in transmission resource group 2, and the transmission resources in transmission resource group 2 are used for downlink reception.

[0147] In some implementations, if the first device detects a DCI in monitoring opportunity group 1, it can determine the transmission resources in transmission resource group 1 scheduled by the DCI, and perform uplink transmission on the transmission resources in transmission resource group 1. If the first device detects a DCI in monitoring opportunity group 2, it can determine the transmission resources in transmission resource group 2 scheduled by the DCI, and perform downlink reception on the transmission resources in transmission resource group 2.

[0148] In some implementations, in a set of monitoring opportunities, the relative time domain positions between the transmission resources scheduled by the DCI and the transmission resources of the DCI are different.

[0149] The above description of multiple monitoring opportunities in the embodiment of the present application is combined with Example 1. The following description of the configuration method of the monitoring opportunities in the embodiment of the present application is combined with Example 2. It should be understood that the configuration method described in combination with Example 2 can be used to configure any of the monitoring opportunities described above. Of course, in the embodiment of the present application, the configuration method described in Example 2 and the monitoring opportunities described in Example 1 can be used independently of each other.

[0150] Example 2: Configuration of multiple monitoring opportunities

[0151] In some implementations, the method further includes: the second device sending first configuration information to the first device, where the first configuration information is used to configure multiple monitoring opportunities, or in other words, the first configuration information is used to configure a search space for the DCI.

[0152] Accordingly, in some implementations, the first device monitors DCI on multiple monitoring opportunities based on the first configuration information. In other words, the first device monitors DCI in the search space based on the first configuration information.

[0153] In some implementations, the first configuration information includes one or more of the following: information for indicating a first duration; information for indicating frequency domain resources corresponding to the DCI; information for indicating the DCI format; information for indicating the number of time domain units corresponding to the DCI; information for indicating first identification information corresponding to the first device; information for indicating the time domain positions of multiple monitoring opportunities; information for indicating the number of monitoring opportunities included in multiple monitoring opportunities; information for indicating the maximum number or minimum number of times the first device monitors the DCI in multiple monitoring opportunities; and information for indicating the time interval between two adjacent groups of monitoring opportunities in the time domain.

[0154] Taking the first configuration information as an example of information indicating the first duration, in some implementations, the first configuration information may include information indicating the first duration. For example, the first configuration information may carry one or more of the following information used to determine the first duration: the number of monitoring opportunities corresponding to the first duration, the time interval between two adjacent monitoring opportunities, and the number of time domain resources occupied by one monitoring opportunity.

[0155] Assuming that a set of monitoring opportunities includes N monitoring opportunities, and the time interval between two adjacent monitoring opportunities is P1 time domain units, the number of time domain units included in the first duration T1 can be determined by the formula T1 = (N-1) * P1, or by the formula T1 = N * P1. The time domain unit can be, for example, a subframe, a time slot, or a time domain symbol. A subframe corresponds to a duration of 1 millisecond.

[0156] Assuming that a group of monitoring opportunities includes N monitoring opportunities, one monitoring opportunity corresponds to M time domain symbols, and one time slot includes L time domain symbols, the number of time domain symbols contained in the first time length T1 can be determined by the formula T1 = (N-1)*P1*L, or can be determined by the formula T1 = (N-1)*P1*L+M.

[0157] Assuming that a group of monitoring opportunities includes N monitoring opportunities, one monitoring opportunity corresponds to M time domain symbols, and the time interval between two adjacent monitoring opportunities is P1 time domain symbols, then the number of time domain symbols contained in the first time length T1 can be determined by the formula T1 = (N-1)*P1, or can be determined by the formula T1 = (N-1)*P1+M.

[0158] Of course, in the embodiment of the present application, the first configuration information may directly indicate the first duration. For example, the first configuration information may carry the number of time domain units corresponding to the first duration, where the time domain unit may be, for example, a time domain symbol, a time slot, a subframe, etc. One subframe corresponds to a duration of 1 millisecond.

[0159] Taking the first configuration information as an example of indicating the frequency domain resources corresponding to the DCI, in some implementations, the first configuration information may carry index information of the physical resource block (PRB) corresponding to the transmission resource carrying the DCI. In other implementations, the first configuration information may carry channel index information corresponding to the transmission resource carrying the DCI.

[0160] For example, a DCI occupies K PRBs in the frequency domain. Accordingly, the first configuration information includes index information of the K PRBs, or the first configuration information includes index information corresponding to the first PRB among the K PRBs and the value of K to indicate the PRB corresponding to the DCI monitoring performed by the first device.

[0161] For another example, a DCI occupies a channel in the frequency domain, and a channel corresponds to a 180 kHz bandwidth. Accordingly, the first configuration information includes channel index information to indicate the channel corresponding to the DCI monitoring performed by the first device.

[0162] For example, the first configuration information may be used to indicate the DCI format. Accordingly, the DCI format information is the DCI format that the first device needs to monitor when performing DCI monitoring, or the first device may perform DCI monitoring based on the DCI format.

[0163] Taking the example of the first configuration information being used to indicate the number of time domain units corresponding to the DCI, or in other words, the first configuration information being used to indicate the number of time units corresponding to the DCI. Taking the time domain unit being a time slot as an example, the first configuration information can be used to indicate that the DCI corresponds to A time slots, where A is a positive integer greater than or equal to 1. Taking the time domain unit being a time domain symbol as an example, the first configuration information can be used to indicate that the DCI corresponds to B time domain symbols, where B is a positive integer greater than or equal to 1. For example, the value of B includes at least one of {14, 28, 42, 56, 70, 84, 140, 280}.

[0164] Taking the first configuration information used to indicate the first identification information corresponding to the first device as an example, in some implementations, the first device corresponding to the first identification information can monitor the DCI configured by the first configuration information, or in other words, the first identification information is used to indicate the first device that monitors the DCI.

[0165] In some implementations, the first identification information may be determined based on identification information of the first device, where the identification information is pre-configured in the first device, or the identification information is fixed in the first device when the first device leaves the factory, or the identification information is an inherent identification of the first device.

[0166] In some implementations, the first identification information corresponds to the identification information reported by the first device to the second device, or in other words, the first identification information is associated with the identification information reported by the first device to the second device, or in other words, the first identification information is determined based on the identification information reported by the first device to the second device.

[0167] For example, the second device is a network device, and the first device can send the second identification information to the network device. Accordingly, when configuring the first identification information associated with the DCI, the network device can determine the first identification information based on the second identification information.

[0168] In the embodiments of the present application, there is no limitation on the method for determining the first identification information. In some implementations, the first identification information may be the same as the second identification information. In other implementations, the first identification information corresponds to part of the bits of the second identification information. For example, the second identification information may correspond to 48 bits, and the first identification information may be the 16 low-order bits of the second identification information. For another example, the second identification information may correspond to 48 bits, and the first identification information may be the 24 low-order bits of the second identification information. For another example, the second identification information may correspond to 48 bits, and the first identification information may be the 32 low-order bits of the second identification information. For another example, the second identification information may correspond to 48 bits, and the first identification information may be the 16 high-order bits of the second identification information. For another example, the second identification information may correspond to 48 bits, and the first identification information may be the 24 high-order bits of the second identification information. For another example, the second identification information may correspond to 48 bits, and the first identification information may be the 32 high-order bits of the second identification information.

[0169] In some implementations, the first identification information includes common identification information, where the common identification information can be understood as common identification information of multiple first devices.

[0170] Taking the first configuration information used to indicate the time domain positions of multiple monitoring opportunities as an example, in some implementations, the information used to indicate the time domain positions of multiple monitoring opportunities includes one or more of the following: period information corresponding to multiple monitoring opportunities; time domain position information of the first monitoring opportunity among multiple monitoring opportunities; time interval information between multiple monitoring opportunities and the first time domain position; time interval information between two adjacent monitoring opportunities among multiple monitoring opportunities.

[0171] In some implementations, the period information corresponding to the multiple monitoring opportunities can be used to determine the time interval between two adjacent monitoring opportunities in the multiple monitoring opportunities. In the embodiments of the present application, the solution of determining the time domain positions of the multiple monitoring opportunities based on the periods corresponding to the multiple monitoring opportunities can be applicable to scenarios where the multiple monitoring opportunities have periodicity.

[0172] In some implementations, the time interval between two adjacent monitoring opportunities in the aforementioned multiple monitoring opportunities can be replaced by the time interval between two adjacent monitoring opportunities in the time domain in the multiple monitoring opportunities. In the embodiments of the present application, the solution of determining the time domain positions of multiple monitoring opportunities based on the time interval between two adjacent monitoring opportunities can be applicable to scenarios where the multiple monitoring opportunities have or have no periodicity.

[0173] In some implementations, the information used to indicate the time domain positions of multiple monitoring opportunities includes the time domain position information of the first monitoring opportunity among the multiple monitoring opportunities. It can be understood that the time domain positions of other monitoring opportunities among the multiple monitoring opportunities except the first monitoring opportunity can be determined based on the time domain position of the first monitoring opportunity.

[0174] The first monitoring opportunity mentioned above can be understood as the monitoring opportunity with the earliest time domain position among the multiple monitoring opportunities. Of course, in the embodiment of the present application, the time domain positions of the multiple monitoring opportunities can also be determined based on the monitoring opportunity with the latest time domain position among the multiple monitoring opportunities, or the time domain positions of the multiple monitoring opportunities can be determined based on a certain monitoring opportunity among the multiple monitoring opportunities.

[0175] In some implementations, the time intervals between the multiple monitoring opportunities and the first time domain position can be understood as time domain offsets of the time domain positions of the multiple monitoring opportunities relative to the first time domain position.

[0176] Take the example of the first configuration information being used to indicate the number of monitoring opportunities included in multiple monitoring opportunities, or in other words, the first configuration information is used to indicate the number of monitoring opportunities included in the first time length, or in other words, the first configuration information is used to indicate the number of monitoring opportunities included in a group of monitoring opportunities, or in other words, the first configuration information is used to indicate the number of multiple monitoring opportunities associated with the first time domain position.

[0177] In some scenarios, multiple monitoring opportunities may belong to one monitoring opportunity group. Accordingly, the number of monitoring opportunities in the multiple monitoring opportunities may be understood as the number of monitoring opportunities included in one monitoring opportunity group.

[0178] Taking the example of the first configuration information being used to indicate the maximum number of times the first device monitors DCI in multiple monitoring opportunities, in some implementations, the maximum number of times the first device monitors DCI in multiple monitoring opportunities may be an upper limit value, that is, the maximum number or upper limit value is used to indicate the upper limit of the number of times the first device monitors DCI based on multiple monitoring opportunities. Typically, the maximum number is less than or equal to (or less than or equal to) the total number of multiple monitoring opportunities. In other implementations, the first configuration information is used to indicate the minimum number of times the first device monitors DCI in multiple monitoring opportunities, and the minimum number of times the first device monitors DCI in multiple monitoring opportunities may be a lower limit value, that is, the minimum number or lower limit value is used to indicate the lower limit of the number of times the first device monitors DCI based on multiple monitoring opportunities.

[0179] It should be noted that the above-mentioned maximum number and minimum number can be understood as being used to limit the number of times the first device actually monitors DCI, wherein the maximum number or minimum number of times the first device monitors DCI may be different from the number of times the first device actually monitors DCI. In other words, the number of times the first device actually monitors DCI (or, the number of times the first device successfully monitors DCI) may be less than or equal to (or less than or equal to) the maximum number of times the first device monitors DCI; the number of times the first device actually monitors DCI (or, the number of times the first device successfully monitors DCI) may be less than or equal to (or less than or equal to) the minimum number of times the first device monitors DCI, or the number of times the first device actually monitors DCI (or, the number of times the first device successfully monitors DCI) may be greater than the minimum number of times the first device monitors DCI.

[0180] For example, the first configuration information is used to indicate the time interval between two adjacent groups of monitoring opportunities in the time domain, where the multiple monitoring opportunities belong to one of the two groups of monitoring opportunities. Alternatively, the first configuration information is used to indicate the time interval between the first durations corresponding to the two adjacent groups of monitoring opportunities.

[0181] The above describes the multiple monitoring opportunities in the embodiment of the present application in combination with Example 1, and describes the first configuration information in the embodiment of the present application in combination with Example 2. The following describes the way in which the first device monitors DCI in the embodiment of the present application in combination with Example 3. It should be noted that the scheme introduced in Example 3 can be combined with Example 1, that is, the multiple monitoring opportunities for DCI monitoring in Example 3 can be any of the multiple monitoring opportunities introduced in Example 1. The scheme introduced in Example 3 can be combined with Example 2, that is, the multiple monitoring opportunities for DCI monitoring in Example 3 can be configured based on the first configuration information introduced in Example 2. Of course, in the embodiment of the present application, Examples 1 to 3 can be embodiments used independently of each other.

[0182] Example 3: DCI Monitoring Method

[0183] The following describes the DCI monitoring method in the embodiment of the present application in combination with methods 1 to 3.

[0184] In approach 1, the first device stops monitoring after detecting DCI once in multiple monitoring opportunities. That is, the above method further includes: in response to detecting DCI in multiple monitoring opportunities, the first device stops monitoring DCI.

[0185] In an embodiment of the present application, when the first device is configured to perform DCI monitoring based on multiple monitoring opportunities, if one DCI is detected, the monitoring is stopped, which helps to reduce the energy consumed by the first device in performing DCI monitoring.

[0186] In some implementations, if the first device detects a DCI message during multiple monitoring opportunities, it stops DCI monitoring and performs uplink transmission (or downlink reception) based on the DCI scheduling. If, at the time of uplink transmission (or downlink reception), the energy of the first device is low and the uplink transmission (or downlink reception) cannot be completed, the network device can perform retransmission scheduling, which helps to improve the success rate of the first device's uplink transmission (or downlink reception).

[0187] In mode 2, the first device performs DCI monitoring based on the maximum number or the minimum number of times the first device detects DCI in multiple monitoring opportunities.

[0188] Taking the maximum number of times the first device monitors DCI in multiple monitoring opportunities as K as an example, in some implementations, the above method also includes: in response to monitoring DCI K times in multiple monitoring opportunities, the first device stops monitoring DCI, where K is a positive integer greater than or equal to 1.

[0189] Assuming that the maximum number of times the first device monitors DCI is K, the first device monitors DCI in multiple monitoring opportunities until it monitors DCI K times, and then stops monitoring DCI. The maximum number can be found in the relevant description of Example 2.

[0190] In some scenarios, the first device may not have detected DCI K times, and multiple monitoring opportunities have ended. In this case, the first device may also stop monitoring DCI. That is, the first device monitors DCI during multiple monitoring opportunities until it detects DCI K times or the multiple monitoring opportunities have ended, at which point it stops monitoring DCI. In other words, the maximum number of times the first device needs to detect DCI is K, and the number of times the first device actually detects DCI based on multiple monitoring opportunities is K1, where K1 ≤ K and K1 is a positive integer.

[0191] In some implementations, the first device may select a target DCI from the DCI monitored K1 times, and determine the transmission resources for uplink transmission (or downlink reception) based on the target DCI, wherein the manner in which the first device selects the target DCI is not limited. For example, the manner in which the first device selects the target DCI may be determined based on the implementation of the first device. For another example, the manner in which the first device selects the target DCI may be determined based on the energy of the first device corresponding to the transmission resource it schedules, that is, the first device may select the target DCI corresponding to the target transmission resource, wherein the energy of the target transmission resource corresponding to the first device is higher than the energy threshold. For another example, the manner in which the first device selects the target DCI may be randomly selected.

[0192] Taking the minimum number of times the first device monitors DCI in multiple monitoring opportunities as H as an example, in some implementations, the above method also includes: in response to monitoring DCI H times in multiple monitoring opportunities, the first device stops monitoring DCI, where H is a positive integer greater than or equal to 1.

[0193] Assuming that the minimum number of times the first device monitors DCI is H, the first device monitors DCI in multiple monitoring opportunities until H DCIs are monitored, and then stops monitoring DCI. The minimum number can be found in the relevant description of Example 2.

[0194] In some scenarios, the first device may not detect DCI H times, and multiple monitoring opportunities may have ended. In this case, the first device may also stop monitoring DCI. That is, the first device monitors DCI during multiple monitoring opportunities until it detects DCI H times or the multiple monitoring opportunities have ended, at which point it stops monitoring DCI. In other words, the minimum number of times the first device needs to detect DCI is H, and the number of times the first device actually detects DCI based on multiple monitoring opportunities is H1, where H1 ≤ H and H1 is a positive integer.

[0195] In some implementations, the first device may select a target DCI from the DCI monitored H1 times, and determine the transmission resources for uplink transmission (or downlink reception) based on the target DCI, wherein the manner in which the first device selects the target DCI is not limited. For example, the manner in which the first device selects the target DCI may be determined based on the implementation of the first device. For another example, the manner in which the first device selects the target DCI may be determined based on the energy of the first device corresponding to the transmission resource it schedules, that is, the first device may select the target DCI corresponding to the target transmission resource, wherein the energy of the target transmission resource corresponding to the first device is higher than the energy threshold. For another example, the manner in which the first device selects the target DCI may be randomly selected.

[0196] In mode 3, the DCI monitored in multiple monitoring opportunities is used to schedule multiple transmission resources for the first device. At this time, the first device can select a suitable transmission resource from the multiple transmission resources for uplink transmission or downlink reception.

[0197] That is, assuming that the DCI monitored by the multiple monitoring opportunities includes a first DCI and a second DCI, and the monitoring opportunity corresponding to the second DCI is later in the time domain than the monitoring opportunity corresponding to the first DCI, and the second DCI is used to schedule the first transmission resource, then if the first device detects the first DCI and the energy collected by the first device at the time corresponding to the first transmission resource is greater than the energy threshold, the first device performs uplink transmission or downlink reception on the first transmission resource.

[0198] In some implementations, the first DCI is used to schedule the second transmission resource, and the energy collected by the first device at a time corresponding to the second transmission resource is lower than an energy threshold.

[0199] In other words, the DCIs transmitted over multiple monitoring opportunities (including the above-mentioned first DCI and second DCI) can be associated with a group of transmission resources. When the first device detects one of the DCIs, it can determine the corresponding uplink transmission (or downlink reception) transmission resource in the group of transmission resources associated with the DCI. Assuming that the first device detects the first DCI, it can determine the second transmission resource scheduled by the first DCI. At this time, if the energy of the first device is lower than the energy threshold at the transmission moment corresponding to the second transmission resource, the first device cannot perform uplink transmission (or downlink reception). It is necessary to wait until the energy of the first device exceeds the energy threshold before uplink transmission (or downlink reception) can be performed, and the transmission resource corresponding to the energy of the first device exceeding the energy threshold is the first transmission resource scheduled by the second DCI. Since the DCIs transmitted over multiple monitoring opportunities are all transmission resources used to schedule the first device to perform uplink transmission (or downlink reception), the first device can perform uplink transmission (or downlink reception) based on the first transmission resource scheduled by the second DCI.

[0200] The following describes the DCI monitoring method described in Method 3 of the embodiment of the present application in conjunction with Figure 14. As shown in Figure 14, four monitoring opportunities are associated with one SS transmission resource, and the four monitoring opportunities include a monitoring opportunity for the first DCI and a monitoring opportunity for the second DCI, wherein the first DCI is used to schedule the second transmission resource, and the second DCI is used to schedule the first transmission resource.

[0201] If the first device detects the first DCI in the second monitoring opportunity and determines the second transmission resource based on the first DCI. The transmission moment of the second transmission resource corresponds to the energy of the first device being lower than the energy threshold, therefore, the first device cannot use the second transmission resource. However, the first transmission resource scheduled by the second DCI transmitted in the fourth monitoring opportunity corresponds to the energy of the first device being higher than the energy threshold, therefore, the first device can use the first transmission resource. That is to say, even if the first device does not detect the second DCI in the fourth monitoring opportunity (for example, because the energy of the first device is lower than the energy threshold), the first device can determine the first transmission resource, therefore, the first device can use the first transmission resource.
