Communication methods, communication devices, storage media and software products

[0001] This application claims priority to Chinese Patent Application No. 202411989777.5, filed on December 27, 2024, entitled "Communication Method, Communication Apparatus, Storage Medium and Program Product", and to Chinese Patent Application No. 202510424137.8, filed on April 4, 2025, both of which are incorporated herein by reference in their entirety. Technical Field

[0002] This application relates to the field of communications, and in particular to communication methods, communication devices, storage media, and program products. Background Technology

[0003] With the development of communication technology, people have increasingly higher requirements for power consumption and latency. In current mobile communication systems, terminals need to be periodically woken up once per discontinuous reception (DRX) cycle. When the terminal is in a woken-up state, but there is no signaling or data service transmission during the wake-up period, the terminal is in an invalid wake-up state, and the power consumption during this period accounts for the main proportion of the terminal's overall power consumption. If the terminal is only woken up when signaling or data services need to be transmitted, such as receiving paging messages, the terminal's power consumption can be significantly reduced. However, in some scenarios with high latency requirements, it is necessary to support low power consumption mechanisms while ensuring low latency.

[0004] In one known communication method, higher energy efficiency is achieved by triggering the main radio (MR) to wake up using a low-power wake-up signal. When the MR is on, it can be used for data transmission and reception; when it is off or in sleep mode, a separate receiver (e.g., a low-power wake-up receiver, LP-WUR) with ultra-low power consumption is used to receive the signal.

[0005] However, in the above communication method, the terminal sometimes misses the physical downlink control channel (PDCCH) activated by the low-power signal, resulting in information transmission delay; but sometimes it will continuously monitor (or detect) whether there is a PDCCH, resulting in high power consumption. Summary of the Invention

[0006] This application provides a communication method, communication device, storage medium, and program product that specifies when a terminal monitors the PDCCH, or when it does not monitor the PDCCH.

[0007] In a first aspect, a communication method is provided, which can be executed by a first communication device. For example, it can be executed by the entire first communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the first communication device, or by a logic module or software capable of implementing all or part of the functions of the first communication device. This application does not limit the scope of the method.

[0008] The first communication device may be a terminal, including but not limited to: mobile phone, tablet computer, computer with wireless transceiver function, virtual reality (VR), or augmented reality (AR), etc. This application does not limit the specific type of terminal.

[0009] For example, the method includes: determining time-domain resources for monitoring low-power signals; monitoring a PDCCH, the time-domain resources for monitoring the PDCCH being related to the time-domain resources for monitoring the low-power signals and a first condition, the first condition including periodic resources configured for the terminal.

[0010] Based on the above technical solution, when the terminal is configured with periodic resources, the location for monitoring the PDCCH or entering the low-power signal monitoring mode is determined by comprehensively considering the positional relationship between the time-domain resources for monitoring the PDCCH, the time-domain resources for monitoring low-power signals, and the configured periodic resources. Thus, the terminal can clearly determine the location for monitoring the PDCCH or entering the low-power signal monitoring mode. Furthermore, this solution can meet the needs of terminals with different energy-saving or latency requirements, which is beneficial for energy saving or ensuring service capacity.

[0011] In conjunction with the first aspect, in some possible implementations, the terminal is configured with periodic resources including one or more of the following: the terminal is activated with semi-persistent scheduling (SPS); or the terminal is activated with configured grant (CG); or the terminal is configured with CG.

[0012] SPS allows for semi-static configuration of radio resources, which are periodically allocated to a specific terminal.

[0013] By configuring periodic SPS or CG resources, the UE can use periodic resources to transmit downlink or uplink data, reducing the data transmission latency of the terminal. This application involves two types of CGs: one type of CG needs to be activated after being configured, and the other type of CG can be used as soon as it is configured.

[0014] In conjunction with the first aspect, in some possible implementations, the time-domain resources of the monitored PDCCH are related to the time-domain resources of the monitored low-power signal and the first condition, including: when the time-domain resources of the monitored low-power signal overlap with the period during which the terminal is in the wake-up process, the interval between the start position of the monitored PDCCH time-domain resources and the start position of the periodic resource is a first interval, and the monitored PDCCH time-domain resources are after the start position of the periodic resource; or, the interval between the start position of the monitored PDCCH time-domain resources and the end position of the monitored low-power signal time-domain resources is a second interval, and the monitored PDCCH time-domain resources are after the end position of the monitored low-power signal time-domain resources, and the terminal is at the start position of the monitored PDCCH time-domain resources. The terminal is in a first operating mode, which is a mode in which low-power signals are not monitored, wherein the first interval is greater than or equal to 0 and the second interval is greater than or equal to 0; or, in the case where the time-domain resources for monitoring low-power signals overlap with the periodic resources, the interval between the start position of the time-domain resources for monitoring PDCCH and the start position of the periodic resources is a third interval, and the time-domain resources for monitoring PDCCH are after the start position of the periodic resources; or, the interval between the start position of the time-domain resources for monitoring PDCCH and the end position of the time-domain resources for monitoring low-power signals is a fourth interval, and the time-domain resources for monitoring PDCCH are after the end position of the time-domain resources for monitoring low-power signals, wherein the third interval is greater than 0 and the fourth interval is greater than or equal to 0.

[0015] In this application, the first operating mode (i.e., the mode that does not monitor low-power signals) may include, but is not limited to, one or more of the following: a mode capable of PDCCH transmission; or a mode capable of physical downlink shared channel (PDSCH) transmission; or a mode capable of physical uplink control channel (PUCCH) transmission; or a mode capable of physical uplink shared channel (PUSCH) transmission; or a mode with MR enabled; or a mode with decoding capability; or a mode capable of transmitting preambles; or a mode capable of performing random access procedures; or a mode with demodulation capability.

[0016] In this application, the second operating mode (i.e., the mode for monitoring low-power signals) may include, but is not limited to, one or more of the following: a mode with the low-power (LP) interface enabled; or a mode with only envelope monitoring capability; or a mode with only correlation monitoring capability; or a mode with only sequence monitoring capability; or a mode with only correlation monitoring capability and envelope monitoring capability; or a mode with only the RF front-end enabled; or a mode with the baseband disabled; or a mode capable of receiving PDCCH, etc. The LR interface is implemented using a simple circuit or chip, resulting in low power consumption. The specific form of the LP interface is not limited in this application. For example, the LP interface can be implemented using a wake-up receiver (WUR), an LP-WUR, a low-power radio (LR), a wake-up module, or a wake-up circuit.

[0017] In this application, WUR can refer to a wake-up radio or a wake-up receiver. WUR in this application is interchangeable with LP-WUR, LR, wake-up module, or wake-up circuit.

[0018] In conjunction with the first aspect, in some possible implementations, when the first interval is equal to 0, the start position of the time-domain resource of the monitoring PDCCH is located at the start position of the periodic resource; or, when the first interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the periodic resource; or, when the second interval is equal to 0, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal; or, when the third interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the periodic resource; or, when the fourth interval is equal to 0, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal.

[0019] Secondly, a communication method is provided, which can be executed by a second communication device. For example, it can be executed by the second communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the second communication device, or by a logic module or software capable of implementing all or part of the functions of the second communication device. This application does not limit the scope of the method.

[0020] The second communication device may be, for example, a network device, which may include, but is not limited to, evolved node B (eNB) in a long term evolution (LTE) system, 5th generation (5G) mobile communication system / new radio (NR) protocol, and next generation node B (gNB) applied to future communication systems, satellites in non-terrestrial networks (NTN), or base stations in future mobile communication systems, etc. This application does not limit the specific type of network device.

[0021] For example, the method includes: determining time-domain resources for transmitting a low-power signal; transmitting a PDCCH, the time-domain resources for transmitting the PDCCH being related to the time-domain resources for transmitting the low-power signal and a first condition, the first condition including configuring periodic resources for the terminal.

[0022] Based on the above technical solution, when configuring periodic resources for the terminal, the location for transmitting the PDCCH is determined by comprehensively considering the positional relationship between the time-domain resources for monitoring the PDCCH, the time-domain resources for transmitting low-power signals, and the periodic resources configured for the terminal. Thus, network devices can clearly determine the location for transmitting the PDCCH, which is beneficial for energy saving.

[0023] In conjunction with the second aspect, in some possible implementations, configuring periodic resources for the terminal includes one or more of the following: activating the terminal's SPS; or activating the terminal's CG; or configuring the terminal's CG.

[0024] In conjunction with the second aspect, in some possible implementations, the time-domain resources for transmitting the PDCCH are related to the time-domain resources for transmitting the low-power signal and the first condition, including: when the time-domain resources for transmitting the low-power signal overlap with the period during which the terminal is in the wake-up process, the interval between the start position of the time-domain resources for transmitting the PDCCH and the start position of the periodic resource is a first interval, and the time-domain resources for transmitting the PDCCH are after the start position of the periodic resource; or, the interval between the start position of the time-domain resources for transmitting the PDCCH and the end position of the time-domain resources for transmitting the low-power signal is a second interval, and the time-domain resources for transmitting the PDCCH are after the end position of the time-domain resources for transmitting the low-power signal, and the terminal is at the start position of the time-domain resources for transmitting the PDCCH. The terminal is in a first working mode, which is a mode in which low-power signals are not monitored, wherein the first interval is greater than or equal to 0 and the second interval is greater than or equal to 0; or, in the case where the time domain resource for transmitting low-power signals overlaps with the periodic resource, the interval between the start position of the time domain resource for transmitting PDCCH and the start position of the periodic resource is a third interval, and the time domain resource for transmitting PDCCH is after the start position of the periodic resource; or, the interval between the start position of the time domain resource for transmitting PDCCH and the end position of the time domain resource for transmitting low-power signals is a fourth interval, and the time domain resource for transmitting PDCCH is after the end position of the time domain resource for transmitting low-power signals, wherein the third interval is greater than 0 and the fourth interval is greater than or equal to 0.

[0025] In conjunction with the second aspect, in some possible implementations, when the first interval is equal to 0, the start position of the time-domain resource for transmitting the PDCCH is located at the start position of the periodic resource; or, when the first interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the periodic resource; or, when the second interval is equal to 0, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the time-domain resource for transmitting the low-power signal; or, when the third interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the periodic resource; or, when the fourth interval is equal to 0, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the time-domain resource for transmitting the low-power signal.

[0026] Thirdly, a communication method is provided, which can be executed by a first communication device. For example, it can be executed by the first communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the first communication device, or by a logic module or software capable of implementing all or part of the functions of the first communication device. This application does not limit this.

[0027] The first communication device may be a terminal, such as including but not limited to: mobile phones, tablets, computers with wireless transceiver capabilities, VR, or AR, etc. This application does not limit the specific type of terminal.

[0028] For example, the method includes: determining time-domain resources for monitoring low-power signals; monitoring a PDCCH, wherein if the time-domain resources for monitoring low-power signals overlap with a period during which the terminal is in a wake-up process, the interval between the start position of the time-domain resources for monitoring the PDCCH and the end position of the time-domain resources for monitoring low-power signals is a fifth interval, the time-domain resources for monitoring the PDCCH are after the end position of the time-domain resources for monitoring low-power signals, and the terminal is in a first operating mode at the start position of the time-domain resources for monitoring the PDCCH, the first operating mode being a mode in which low-power signals are not monitored, wherein the fifth interval is greater than or equal to 0.

[0029] Based on the above technical solution, by clearly defining the monitoring location (or time domain resources) of the PDCCH under different conditions, the terminal can align the monitoring location (or time domain resources) of the PDCCH with the network equipment. This allows the terminal to clearly define the location for monitoring the PDCCH or the location for entering a low-power signal monitoring mode. Furthermore, it can meet the needs of terminals with different energy-saving or latency requirements, which is beneficial for terminal energy saving or ensuring service capacity.

[0030] In conjunction with the third aspect, in some possible implementations, when the fifth interval is equal to 0, the start position of the time-domain resource for monitoring the PDCCH is located at the end position of the time-domain resource for monitoring the low-power signal.

[0031] Combining the first and third aspects, in some possible implementations, the time-domain resources for monitoring low-power signals are continuous.

[0032] Combining the first and third aspects, in some possible implementations, the low-power signal transmitted in the time-domain resource for monitoring low-power signals is used to indicate whether there is a PDCCH transmission in the time-domain resource for monitoring PDCCH.

[0033] Fourthly, a communication method is provided, which can be executed by a second communication device. For example, it can be executed by the second communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the second communication device, or by a logic module or software capable of implementing all or part of the functions of the second communication device. This application does not limit the scope of the method.

[0034] The second communication device may be a network device, including but not limited to: eNB in ​​LTE system, 5G mobile communication system / NR protocol and gNB, satellite in NTN or base station in future mobile communication system, etc. This application does not limit the specific type of network device.

[0035] For example, the method includes: determining time-domain resources for transmitting low-power signals; transmitting a PDCCH, wherein, if the time-domain resources for transmitting low-power signals overlap with the time period during which the terminal is in a wake-up process, the interval between the start position and the end position of the time-domain resources for transmitting PDCCH is a fifth interval, the time-domain resources for transmitting PDCCH are after the end position of the time-domain resources for transmitting low-power signals, and the terminal is in a first operating mode at the start position of the time-domain resources for transmitting PDCCH, the first operating mode being a mode that does not monitor low-power signals, wherein the fifth interval is greater than or equal to 0.

[0036] Based on the above technical solution, by specifying the PDCCH transmission location (or time domain resource) under different circumstances, network devices can align the PDCCH transmission location (or time domain resource) with the terminal. Furthermore, network devices can transmit the PDCCH in advance, which helps reduce service transmission latency. Additionally, the ability to specify the PDCCH transmission location by the network device is beneficial for energy saving.

[0037] In conjunction with the fourth aspect, in some possible implementations, when the fifth interval is equal to 0, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the time-domain resource for transmitting the low-power signal.

[0038] Combining the second and fourth aspects, in some possible implementations, the time-domain resources for transmitting low-power signals are continuous.

[0039] In combination with the second and fourth aspects, in some possible implementations, the low-power signal transmitted in the time-domain resource where the low-power signal is transmitted is used to indicate whether there is a PDCCH transmission in the time-domain resource where the PDCCH is transmitted.

[0044] Based on the above technical solution, by comprehensively considering at least two of the following factors—time-domain resources for monitoring low-power signals, channel measurement results of the terminal, and indication information indicating entry into the second operating mode or entry into the second operating mode after the timer stops—the conditions for the terminal to enter the second operating mode are restricted. Thus, the terminal can clearly determine when to enter the second operating mode. Furthermore, it can also meet different energy-saving or latency requirements, which is beneficial for terminal energy saving or ensuring service capacity.

[0072] In conjunction with the eighth aspect, in some possible implementations, the method further includes sending the PDCCH at the second opportune moment.

[0073] It should be noted that the first to tenth intervals in this application may be indicated by the same instruction information, or by different instruction information, or may be pre-configured or pre-defined. This application does not impose any limitations on this.

[0074] Ninthly, a communication method is provided, which can be executed by a first communication device, for example, by the first communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the first communication device, or by a logic module or software capable of implementing all or part of the functions of the first communication device. This application does not limit the scope of the method.

[0075] The first communication device may be a terminal, such as including but not limited to: mobile phones, tablets, computers with wireless transceiver capabilities, VR, or AR, etc. This application does not limit the specific type of terminal.

[0076] For example, the method includes: receiving indication information from the network device, the indication information being used to indicate the M timings; and receiving a DCI at one or more of the M timings, the DCI being used to schedule PDSCH.

[0077] Based on the above technical solutions, by clearly defining the behavior of the terminal and limiting the signal reception latency, network capacity can be guaranteed. Furthermore, terminals with different energy-saving or latency requirements can be accommodated, which is beneficial for energy conservation or ensuring service capacity.

[0078] In a tenth aspect, a communication method is provided, which can be executed by a second communication device. For example, it can be executed by the second communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the second communication device, or by a logic module or software capable of implementing all or part of the functions of the second communication device. This application does not limit the scope of the method.

[0079] The second communication device may be a network device, including but not limited to: eNB in ​​LTE system, 5G mobile communication system / NR protocol and gNB, satellite in NTN or base station in future mobile communication system, etc. This application does not limit the specific type of network device.

[0080] For example, the method includes: determining M timings of a first terminal, the M timings belonging to M adjacent non-continuous reception periods, where M is an integer greater than or equal to 2; transmitting M DCIs at the M timings, the M DCIs being used to schedule M PDSCHs, the M PDSCHs transmitting the same information.

[0081] Based on the above technical solutions, by clearly defining the behavior of network devices and limiting the signal reception latency of terminals, network capacity can be guaranteed. Furthermore, it is possible to meet the different energy-saving or latency requirements of terminals, which is beneficial for energy conservation or ensuring service capacity.

[0082] In conjunction with the tenth aspect, in some possible implementations, the method further includes: sending indication information to the first terminal, the indication information being used to indicate the M timings.

[0083] In conjunction with aspects nine and ten, in some possible implementations, the DCI is scrambled with either the paging radio network temporary identifier (P-RNTI) or the cell radio network temporary identifier (C-RNTI).

[0084] Eleventhly, a communication method is provided, which can be executed by a first communication device. For example, it can be executed by the first communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the first communication device, or by a logic module or software capable of implementing all or part of the functions of the first communication device. This application does not limit this.

[0085] The first communication device may be a terminal, such as including but not limited to: mobile phones, tablets, computers with wireless transceiver capabilities, VR, or AR, etc. This application does not limit the specific type of terminal.

[0086] For example, the method includes: monitoring or receiving a first signal for determining to monitor a PDCCH; not monitoring or stopping receiving the first signal within a time range from a first time prior to the start time of a first resource to the start time of the first resource, the start time of the first resource being determined based on resource configuration information received from a network device; and / or, from the start time of the first resource, performing one or more of the following: not monitoring or not receiving the first signal; or monitoring or receiving the PDCCH; or monitoring or receiving a PDSCH; or receiving a reference signal; or sending a scheduling request; or sending a physical random access channel; or sending a reference signal; or sending a PUCCH; or sending a PUSCH.

[0087] Based on the above technical solution, when resource configuration information is obtained, the terminal can no longer receive the first signal, but instead use the resource transmission information determined by the resource configuration information to reduce the transmission delay of the information.

[0088] In conjunction with the eleventh aspect, in some possible implementations, the method further includes: monitoring or receiving the first signal starting from a second time after the start time of the first resource.

[0089] Based on the above technical solution, after the terminal has transmitted all the information, it can start monitoring or receiving the first signal, thereby achieving the effect of energy saving.

[0090] In conjunction with the eleventh aspect, in some possible implementations, the first time is determined based on first indication information received from the network device; or, the first time is predefined.

[0091] In conjunction with the eleventh aspect, in some possible implementations, the method further includes: sending second indication information for determining a third time, the third time being the first time supported by the terminal.

[0092] In conjunction with the eleventh aspect, in some possible implementations, the method further includes: sending third indication information for determining a fourth time, which is the first time desired by the terminal.

[0093] In a twelfth aspect, a communication method is provided, which can be executed by a second communication device. For example, it can be executed by the second communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the second communication device, or by a logic module or software capable of implementing all or part of the functions of the second communication device. This application does not limit the scope of the method.

[0094] The second communication device may be a network device, including but not limited to: eNB in ​​LTE system, 5G mobile communication system / NR protocol and gNB, satellite in NTN or base station in future mobile communication system, etc. This application does not limit the specific type of network device.

[0095] For example, the method includes: sending resource configuration information for determining the start time of a first resource.

[0096] Based on the above technical solution, when configuring resource configuration information to the terminal, the terminal no longer needs to receive the first signal, but can instead use the resource transmission information determined by the resource configuration information to reduce the transmission delay of the information.

[0097] In conjunction with the twelfth aspect, in some possible implementations, the method further includes: sending a first signal for triggering terminal monitoring of the PDCCH.

[0098] In conjunction with the twelfth aspect, in some possible implementations, the method further includes: not transmitting the first signal during the time period from a first time prior to the start time of the first resource to the start time of the first resource; and / or, from the start time of the first resource, performing one or more of the following: not transmitting the first signal; or transmitting the PDCCH; or transmitting the PDSCH; or transmitting a reference signal; or receiving a scheduling request; or receiving a physical random access channel; or receiving a reference signal; or receiving a PUCCH; or receiving a PUSCH.

[0099] In conjunction with the twelfth aspect, in some possible implementations, the method further includes: sending the first signal starting from a second time after the start time of the first resource.

[0100] In conjunction with the twelfth aspect, in some possible implementations, the method further includes: sending first indication information, which is used to indicate a first time.

[0101] In conjunction with the twelfth aspect, in some possible implementations, this first time is predefined.

[0102] In conjunction with the twelfth aspect, in some possible implementations, the method further includes: receiving second indication information for determining a third time, the third time being the first time supported by the terminal.

[0103] In conjunction with the twelfth aspect, in some possible implementations, the method further includes: sending third indication information for determining a fourth time, which is the first time desired by the terminal.

[0104] In conjunction with aspects eleven and twelfth, in some possible implementations, the resource configuration information includes one or more of the following: configuration information related to SPS; or configuration information related to CG; or other resource configuration information that periodically receives and / or periodically sends information.

[0105] Based on the above technical solutions, regardless of whether the network is configured with SPS, CG, or other periodic resources, as long as the terminal and network equipment have pre-aligned the resources used for information transmission, the terminal can use the method of the eleventh or twelfth aspect to reduce the information transmission latency.

[0106] In conjunction with aspects eleven and twelfth, in some possible implementations, the first resource includes one or more of the following: a resource configured with configuration information related to SPS; or a resource configured with configuration information related to CG; or a resource configured with configuration information for other resources that periodically receive and / or periodically send information.

[0107] In conjunction with aspects eleven and twelfth, in some possible implementations, the second time is determined by one or more of the following: the first resource, discontinuous reception (DRX)-hybrid automatic repeat request (HARQ)-round-trip time (RTT)-timer downlink (TimerDL), and DRX-retransmission-TimerDL.

[0108] In conjunction with aspects eleven and twelfth, in some possible implementations, the length of the fourth time is greater than or equal to the length of the third time.

[0109] Based on the above technical solution, if the fourth time is greater than or equal to the third time, the network device can refer to the fourth time reported by the terminal when configuring the first time. The terminal is more likely to stay in a sleep state for a long time and enter a deep sleep state, which helps the terminal save energy.

[0110] In conjunction with aspects eleven and twelfth, in some possible implementations, the modulation method of the first signal includes one or more of the following: on-off keying modulation, sequence modulation, phase modulation, Zadoff-Chu (ZC) sequence carrying, or frequency shift keying modulation.

[0111] Based on the above technical solution, the first signal uses a simpler modulation method, making terminal processing simpler and helping the terminal save energy.

[0112] In a thirteenth aspect, a communication method is provided, which can be executed by a first communication device. For example, it can be executed by the first communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the first communication device, or by a logic module or software capable of implementing all or part of the functions of the first communication device. This application does not limit the scope of the method.

[0113] The first communication device may be a terminal, such as including but not limited to: mobile phones, tablets, computers with wireless transceiver capabilities, VR, or AR, etc. This application does not limit the specific type of terminal.

[0114] For example, the method includes: when the terminal is enabled or activated to monitor or receive a first signal, and the terminal is configured with resource configuration information, determining a first resource based on the resource configuration information, the first signal being used to determine the monitoring of PDCCH; and performing one or more of the following on the first resource: not monitoring or receiving the PDCCH; or, not monitoring or receiving the PDSCH; or, not receiving a reference signal; or, not sending a scheduling request; or, not sending a physical random access channel; or, not sending a reference signal; or, not sending a PUCCH; or, not sending a PUSCH; or, monitoring or receiving the first signal.

[0115] Based on the above technical solution, when the terminal obtains the resource configuration information, it no longer needs to receive, monitor, or send the above signals or channels on the resources determined by the resource configuration information, which helps to reduce the terminal power consumption.

[0116] In a fourteenth aspect, a communication method is provided, which can be executed by a second communication device. For example, it can be executed by the second communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the second communication device, or by a logic module or software capable of implementing all or part of the functions of the second communication device. This application does not limit the scope of the method.

[0117] The second communication device may be a network device, including but not limited to: eNB in ​​LTE system, 5G mobile communication system / NR protocol and gNB, satellite in NTN or base station in future mobile communication system, etc. This application does not limit the specific type of network device.

[0118] For example, the method includes: enabling or activating monitoring or transmitting a first signal, the first signal being used to trigger a terminal to monitor a physical downlink control channel (PDCCH); transmitting resource configuration information, the resource configuration information being used to determine a first resource; and performing one or more of the following on the first resource: not transmitting the PDCCH; or, not transmitting a physical downlink shared channel (PDSCH); or, not transmitting a reference signal; or, not receiving a scheduling request; or, not receiving a physical random access channel; or, not receiving a reference signal; or, not receiving a physical uplink control channel (PUCCH); or, not receiving a physical uplink shared channel (PUSCH); or, transmitting the first signal.

[0119] Based on the above technical solution, the network device configures resource configuration information to the terminal. When the terminal obtains the resource configuration information, it no longer needs to receive, monitor or send the above signals or channels on the resources determined by the resource configuration information, which helps to reduce the power consumption of the terminal.

[0120] In conjunction with aspects thirteen and fourteen, in some possible implementations, the resource configuration information includes one or more of the following: configuration information related to SPS; or configuration information related to CG; or other resource configuration information that periodically receives and / or periodically sends information.

[0121] Based on the above technical solutions, regardless of whether the network is configured with SPS, CG, or other periodic resources, as long as the terminal and network equipment have pre-aligned the resources used for information transmission, the terminal can use the method of the thirteenth or fourteenth aspect to reduce the information transmission latency.

[0122] In conjunction with aspects thirteen and fourteen, in some possible implementations, the first resource includes one or more of the following: a resource configured with configuration information related to SPS; or a resource configured with configuration information related to CG; or a resource configured with configuration information for other periodically received and / or periodically transmitted information.

[0123] In conjunction with aspects thirteen and fourteen, in some possible implementations, the modulation method of the first signal includes one or more of the following: on-off keying modulation, sequence modulation, phase modulation, ZC sequence carrying, or frequency shift keying modulation.

[0124] Based on the above technical solution, the first signal uses a simpler modulation method, making terminal processing simpler and helping the terminal save energy.

[0125] In a fifteenth aspect, a communication method is provided, which can be executed by a first communication device, for example, by the first communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the first communication device, or by a logic module or software capable of implementing all or part of the functions of the first communication device. This application does not limit the scope of the method.

[0126] The first communication device may be a terminal, such as including but not limited to: mobile phones, tablets, computers with wireless transceiver capabilities, VR, or AR, etc. This application does not limit the specific type of terminal.

[0127] For example, the method includes: if the terminal is enabled or activated to monitor or receive a first signal, the terminal does not expect to be enabled or configured with resource configuration information; and / or, if the terminal is enabled or configured with resource configuration information, the terminal does not expect to be enabled or activated to monitor or receive the first signal.

[0128] Based on the above technical solutions, at any given time, the terminal can only enable or activate monitoring or receiving the first signal, or only be configured with resource configuration information. This avoids the mutual exclusion problem of two actions occurring simultaneously, reducing the complexity of network devices and terminals. Furthermore, by enabling or activating monitoring or receiving the first signal, the terminal does not expect to be configured with resource configuration information, allowing it to remain in the monitoring or receiving state for an extended period. Since the power consumption of monitoring or receiving the first signal is low, energy saving can be achieved. Conversely, by enabling or configuring resource configuration information, the terminal does not expect to be enabled or activated to monitor or receive the first signal, allowing it to transmit information within the resources specified by the configured resource configuration information, reducing information transmission latency.

[0129] In a sixteenth aspect, a communication method is provided, which can be executed by a second communication device. For example, it can be executed by the second communication device itself, or by a component (such as a processor, chip, chip system, etc.) configured in the second communication device, or by a logic module or software capable of implementing all or part of the functions of the second communication device. This application does not limit the scope of the method.

[0130] The second communication device may be a network device, including but not limited to: eNB in ​​LTE system, 5G mobile communication system / NR protocol and gNB, satellite in NTN or base station in future mobile communication system, etc. This application does not limit the specific type of network device.

[0131] For example, the method includes: disabling or configuring resource configuration information when enabling or activating monitoring or sending a first signal; and / or disabling or activating monitoring or sending the first signal when enabling or configuring resource configuration information.

[0132] Based on the above technical solutions, network devices can avoid the mutual exclusion problem of two actions occurring simultaneously by enabling or activating monitoring or sending the first signal, or configuring resource configuration information to the terminal, at any given time, thus reducing the complexity of network devices and terminals. Furthermore, by enabling or activating monitoring or sending the first signal without configuring resource configuration information to the terminal, the terminal can remain in the state of monitoring or receiving the first signal for an extended period. Since the power consumption of the terminal monitoring or receiving the first signal is low, energy saving can be achieved. Conversely, by enabling or configuring resource configuration information to the terminal without enabling or activating monitoring or sending the first signal, the terminal can transmit information within the resources specified by the configured resource configuration information, reducing information transmission latency.

[0133] In conjunction with aspects fifteen and sixteen, in some possible implementations, the resource configuration information includes one or more of the following: configuration information related to SPS; or configuration information related to CG; or other resource configuration information that periodically receives and / or periodically sends information.

[0134] Based on the above technical solutions, regardless of whether the network is configured with SPS, CG, or other periodic resources, as long as the terminal and network equipment have pre-aligned the resources used for information transmission, the terminal can use the method of aspect fifteen or sixteen to reduce the information transmission latency.

[0135] In conjunction with aspects fifteen and sixteen, in some possible implementations, the modulation method of the first signal includes one or more of the following: on-off keying modulation, sequence modulation, phase modulation, ZC sequence carrying, or frequency shift keying modulation.

[0136] Based on the above technical solution, the first signal uses a simpler modulation method, making terminal processing simpler and helping the terminal save energy.

[0179] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0180] To facilitate understanding of the method provided in this application, the following points will be explained first.

[0181] First, in this application, the term "system" can be used interchangeably with "network." This application will present various aspects, embodiments, or features in relation to a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that individual systems may include additional devices, components, modules, etc., and / or may not include all devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches are also possible.

[0182] Second, in this application, the words "exemplarily," "for example," etc., are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as an "example" in this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the word "example" is intended to present the concept in a concrete manner.

[0183] Third, in this application, "instruction" can include direct and indirect instructions, as well as explicit and implicit instructions. The information indicated by a certain piece of information is called the information to be instructed. In the specific implementation process, there are many ways to instruct the information to be instructed, such as, but not limited to, directly instructing the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly instruct the information to be instructed by instructing other information, where there is a relationship between the other information and the information to be instructed. It can also instruct only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. At the same time, common parts of various pieces of information can be identified and uniformly indicated to reduce the instruction overhead caused by individually indicating the same information.

[0184] Furthermore, the specific indication method can also be any existing indication method, such as, but not limited to, the above-mentioned indication methods and their various combinations. Specific details of various indication methods can be found in existing technologies, and will not be repeated here. As can be seen from the above, for example, when multiple pieces of information of the same type need to be indicated, the indication methods for different pieces of information may differ. In the specific implementation process, the required indication method can be selected according to specific needs. This application embodiment does not limit the selected indication method; therefore, the indication methods involved in this application embodiment should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated.

[0185] Fourth, in this application, "predefined" can be understood as standard-defined, which can be implemented by pre-saving corresponding codes, tables, or other means that can be used to indicate relevant information in the device (e.g., including terminal devices). This application does not limit the specific implementation method. "Saving" can refer to saving in one or more memories. One or more memories can be separate settings or integrated into the encoder or decoder, processor, or communication device. One or more memories can also be partially separate settings and partially integrated into the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this application does not limit this. "Configuration" refers to network device configuration, which can be changed through system information block (SIB) or radio resource control (RRC) signaling.

[0186] In addition, the term "predefined" in this application can be replaced with "definition", "predefined", "storage", "pre-storage", "pre-negotiation", "pre-firing", "curing", "pre-configuration" or "pre-configuration", etc.

[0187] Fifth, the “protocol” involved in the embodiments of this application may refer to standard protocols in the field of communication, such as LTE protocol, NR protocol and related protocols applied to future communication systems. The embodiments of this application do not limit this.

[0188] Sixth, in this application, descriptions such as "when," "in the circumstances," "if," and "if" all refer to the fact that the device (e.g., a network device or terminal) will take corresponding actions under certain objective circumstances. They are not time-limited, nor do they require the device (e.g., a network device or terminal) to perform a judgment action during implementation, nor do they imply any other limitations. Unless otherwise specified, "if" and "if" are interchangeable, as are "when" and "in the circumstances." "When" is interchangeable with "if" / "if."

[0189] Seventh, in this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can represent A or B. The "and / or" in the embodiments of this application is merely a description of the relationship between the related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone, where A and B can be singular or plural. Furthermore, in the description of the embodiments of this application, unless otherwise stated, "multiple" refers to two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0190] Eighth, in this application, communication between different devices can refer to direct communication between different devices (i.e., without the need for relaying or forwarding by other devices), or communication between different devices through other devices (i.e., requiring relaying or forwarding by other devices), or communication between a functional unit within a device and other devices through another functional unit. "Sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to a terminal" can be understood as the destination of the information being the terminal, which can include direct sending via the air interface, or indirect sending via the air interface by other units or modules. "Receiving configuration information from a network device" can be understood as the source of the configuration information being the network device, which can include direct reception from the network device via the air interface, or indirect reception from the network device via the air interface by other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0191] In other words, sending and receiving can occur between devices, such as between network devices and terminals; or they can occur within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0192] It is understandable that information may undergo necessary processing, such as encoding and modulation, before being sent from the source to the destination. Similarly, the destination, upon receiving information from the source, can also perform corresponding processing, such as decoding and demodulation, to interpret the valid information from the source. Similar expressions in this application can be understood in a similar way and will not be elaborated further.

[0193] Ninth, in this application, the number of nouns, unless otherwise specified, refers to "singular nouns or plural nouns," that is, "one or more." "At least one" means one or more, and "more than one" means two or more.

[0194] Tenth, the ordinal numbers such as "first" and "second" mentioned in this application are used to distinguish multiple objects, and are not used to limit the size, content, order, sequence, priority, or importance of multiple objects. For example, the first interval and the second interval refer to two different intervals, and do not indicate a difference in the priority or importance of these two conditions.

[0195] It should be noted that the first to tenth intervals in this application may be indicated by the same instruction information, or by different instruction information, or may be pre-configured or pre-defined. This application does not impose any limitations on this.

[0196] Eleventh, in the embodiments of this application, the solutions in each embodiment can be used in a reasonable combination, and the explanations or descriptions of various terms, similar operations, or steps appearing in the embodiments can be referenced or explained to each other in the embodiments, without limitation.

[0197] Twelfth, the technical solutions provided in this application can be applied to various communication systems, such as LTE communication systems, 5G mobile communication systems / NR communication systems, or future mobile communication systems, or other similar communication systems. Other similar communication systems may include wireless fidelity (Wi-Fi), vehicle-to-everything (V2X), and Internet of Things (IoT) systems, etc.

[0198] Thirteenth, in this application, monitoring may be replaced by detection.

[0199] The following will describe in detail the communication systems and scenarios to which the method provided in this application is applicable, with reference to the accompanying drawings.

[0200] Figure 1 is a schematic diagram of the architecture of a communication system applicable to the method provided in this application. Figure 1 shows a schematic diagram of a possible, non-limiting system architecture.

[0201] As shown in Figure 1, the communication system may include a wireless access network 100 and a core network 200. Optionally, the communication system may also include an Internet 300.

[0202] The wireless access network 100 may include at least one network device and at least one terminal. For example, the wireless access network 100 includes two network devices, 110a and 110b, and terminals 120a to 120j. The network architecture shown in Figure 1 is only illustrative; the number of terminals and / or network devices may be fewer or more. The communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application and does not constitute a limitation on the communication system to which the embodiments of this application are applicable. For example, the communication system may also include other devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1. As those skilled in the art will understand, with the evolution of network architecture, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems. When applying the technical solutions of the embodiments of this application to other communication systems, the devices, components, modules, etc. in the embodiments can be replaced with corresponding devices, components, modules in other communication systems without limitation.

[0203] In this embodiment, network equipment refers to (radio)access network ((R)AN) equipment / RAN node. In this embodiment, (R)AN and RAN are interchangeable. RAN can be a cellular system related to the 3rd generation partnership project (3GPP), such as a 5G / NR mobile communication system, or a future-oriented evolution system (such as the sixth generation (6G) mobile communication system). RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), a virtualized RAN (vRAN), NTN, etc. RAN can also be a communication system that integrates two or more of the above systems. RAN equipment can also be called a RAN node, RAN entity, or access node, etc.

[0204] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, or a base station in a future mobile communication system. A RAN node can also be a macro base station, a micro base station, an indoor station, a relay node, a donor / host node, or a radio controller. RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, a RAN node can be a roadside unit (RSU).

[0205] In another possible scenario, a RAN node can be a module or unit that performs some of the functions of a base station; or multiple RAN nodes can collaborate to assist terminal devices in achieving wireless access, with different RAN nodes performing some of the functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). The function of a CU can be implemented by a single entity or by different entities. For example, the function of a CU can be further divided, that is, the control plane and the user plane can be separated and implemented by different entities, namely the control plane CU entity (i.e., CU-control plane (CP) entity) and the user plane CU entity (i.e., CU-user plane (UP) entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the function of the RAN node. The CU and DU can be set up separately or included in the same network element, such as in the baseband unit (BBU). Any of the units among the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by software modules, hardware modules, or a combination of software modules and hardware modules.

[0206] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.

[0207] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU can be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (such as the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); the DU can be configured to implement the functions of the protocol layers below the PDCP layer (such as the Radio Link Control (RLC) layer, the Media Access Control (MAC) layer, and / or the Physical (PHY) layer). For specific descriptions of the above protocol layers, please refer to the relevant 3GPP technical specifications or the technical specifications of other applicable communication protocols.

[0208] The above division of the processing functions of CU and DU according to protocol layers is merely an example; other division methods are also possible, and this application does not limit this. For example, in one design, CU or DU can be further divided into processing functions with protocol layers. In one design, some functions of the RLC layer and the functions of the protocol layer above the RLC layer are located in the CU, while the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are located in the DU.

[0209] In another possible design, the DU and RU collaborate to implement the PHY layer functionality, or, more specifically, a portion of the PHY layer functionality of the DU can be moved to the RU. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways depending on the design. For example, the DU may be configured to implement baseband functions, and the RU may be configured to implement mid-RF functions. Alternatively, the DU may be configured to implement higher-level functions in the PHY layer, and the RU may be configured to implement lower-level functions in the PHY layer, or both lower-level and RF functions. Higher-level functions in the physical layer may include a portion of the physical layer's functionality closer to the MAC layer, and lower-level functions may include another portion of the physical layer's functionality closer to the mid-RF side. This application does not limit the specific functions of the DU and RU. The interface between the DU and RU can be called a fronthaul interface. In one design, the CU may not have a PDCP layer; for example, the CU may only include an RRC layer. The CU-CP may not have PDCP-C. The CU-UP may not have PDCP-U, or may not have a CU-UP. In one design, the DU may not have an RLC layer; for example, the DU may only have a MAC and a higher PHY layer.

[0210] When the RAN is O-RAN, it can also have artificial intelligence (AI) capabilities. For example, O-RAN includes an intelligent controller. The intelligent controller can be a non-real-time RAN intelligent controller (RIC / non-RT RIC / NRT RIC) or a near-real-time RAN intelligent controller (RIC / near-RT RIC / nRT RIC). A non-real-time RIC can be used to implement non-real-time intelligent management of RAN functions, enabling workflows including model training and model updates, and guiding applications / functions in the nRT RIC based on policies. A near-real-time RIC can be used to implement near-real-time intelligent management of the RAN. Through data collection and related operations on the E2 interface, near-real-time control and optimization of O-RAN modules and resources are achieved.

[0211] In this application embodiment, anything capable of data communication with a base station can be considered a terminal. A terminal is also called a terminal device, terminal apparatus, user equipment (UE), mobile station (MS), or mobile terminal (MT), etc. Terminals can be widely used in various scenarios. For example, a terminal can be: a mobile phone, computer, tablet computer, computer with wireless transceiver capabilities, mobile internet device (MID), wearable device, VR device, AR device, wireless terminal in industrial control, wireless terminal in autonomous driving, wireless terminal in remote surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, station (STA), robotic arm, camera, robot, vehicle, drone, helicopter, airplane, ship, or smart home devices (such as televisions, air conditioners, robot vacuums, speakers, set-top boxes), relay, customer premises equipment (CPE), etc.

[0212] Furthermore, in this embodiment, the terminal can also be a terminal device in an IoT system, such as a water meter or electricity meter. IoT is an important component of future information technology development. Its main technical characteristic is connecting objects to networks through communication technology, thereby realizing an intelligent network that enables human-machine interconnection and object-to-object interconnection.

[0213] When a terminal can be applied to V2X, it can also be called a V2X device, such as a smart car, digital car, unmanned car, driverless car, pilotless car, autonomous car, pure electric vehicle (EV), hybrid electric vehicle (HEV), range-extended electric vehicle (REEV), plug-in hybrid electric vehicle (PHEV), new energy vehicle, and roadside unit (RSU).

[0214] The various terminals described above, if located on a vehicle (e.g., placed / installed inside the vehicle), can all be considered vehicle-mounted terminals. A vehicle-mounted terminal can be built into a vehicle's onboard module, onboard unit, onboard component, onboard chip, or onboard unit as one or more components or units. The vehicle can implement the methods of this application through the built-in onboard module, onboard unit, onboard component, onboard chip, or onboard unit. The vehicle-mounted terminal device can be a complete vehicle device, onboard module, vehicle, onboard unit (OBU), roadside unit (RSU), vehicle infotainment system (or onboard transmitting unit) (telematics box, T-box), chip, or system-on-chip (SOC), etc. The aforementioned chip or SOC can be installed in the vehicle, OBU, RSU, or T-box.

[0215] Taking a base station as an example of a network device and a UE as an example of a terminal, the base station and UE can be fixed in location or mobile. The base station and UE can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed on aircraft, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of the base station and UE.

[0216] The roles of base station and UE can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. For UEs 120j that access the radio access network 100 through 120i, 120i is a base station; however, for base station 110a, 120i is a UE, meaning that 110a and 120i can communicate via a radio interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, both base station and UE can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with base station functions, and 120a-120j in Figure 1 can be called communication devices with UE functions.

[0217] Figure 2 is another schematic diagram of the communication system applicable to the method provided in this application. Figure 2 shows a schematic diagram of a possible, non-limiting system architecture. The communication system shown in Figure 2 can be viewed as a simplification of the communication system shown in Figure 1.

[0218] The communication system shown in Figure 2 can be a mobile communication system. Exemplarily, this mobile communication system may include a core network device 210, a radio access network device 220, and at least one terminal (e.g., terminal 230 and terminal 240 shown in Figure 2). The terminal can connect wirelessly to the radio access network device, and the radio access network device can connect wirelessly or via a wired connection to the core network device. The core network device and the radio access network device can be independent physical devices, or the functions of the core network device and the logical functions of the radio access network device can be integrated into the same physical device; alternatively, a single physical device can integrate some of the functions of the core network device and some of the functions of the radio access network device. The terminal can be fixed in location or mobile.

[0219] It is understood that Figure 2 is a schematic diagram of a communication system to which the method provided in this application is applicable. In actual application scenarios, the communication system may also include other network devices, such as wireless relay devices and / or wireless backhaul devices, which are not shown in Figure 2. It is also understood that the embodiments of this application do not limit the number of core network devices, wireless access network devices, and terminals included in the mobile communication system.

[0220] For detailed information about the terminal, please refer to the relevant description in Figure 1 above. For the sake of brevity, it will not be repeated here.

[0221] A wireless access network device is an access device that enables a terminal to access a mobile communication system wirelessly. Wireless access network devices can be base stations (NodeBs), eNodeBs, base stations in 5G mobile communication systems, base stations in future mobile communication systems, or access nodes in Wi-Fi systems, etc. The embodiments of this application do not limit the specific technology or device form used in the wireless access network device.

[0222] Wireless access network devices and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the wireless access network devices and terminals.

[0223] The embodiments of this application can be applied to downlink signal transmission, uplink signal transmission, and device-to-device (D2D) signal transmission. For downlink signal transmission, the transmitting device is a wireless access network device, and the corresponding receiving device can be a terminal. For uplink signal transmission, the transmitting device can be a terminal, and the corresponding receiving device is a wireless access network device. For D2D signal transmission, the transmitting device can be a terminal, and the corresponding receiving device can also be a terminal. The embodiments of this application do not limit the direction of signal transmission.

[0224] Communication between wireless access network devices and terminals, as well as between terminals, can be conducted using licensed spectrum, unlicensed spectrum, or a combination of both. Communication between wireless access network devices and terminals, as well as between terminals, can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or a combination of both. The embodiments of this application do not limit the spectrum resources used between wireless access network devices and terminal devices.

[0225] To facilitate understanding of the communication method provided in this application, the terminology used in this application will be explained in detail below.

[0226] 1. Time Unit: In this application, "time unit" can refer to any unit of time. A time unit can be a radio frame, subframe, slot, mini-slot, orthogonal frequency division multiplexing (OFDM) symbol, hour (h), minute (min), second (s), millisecond (ms), partial OFDM symbol, on-off keying (OOK) symbol, OOK time unit, or a fraction of a millisecond (e.g., 1 / 32ms) time unit. Alternatively, a time unit can be multiple radio frames, multiple subframes, multiple slots, multiple mini-slots, multiple OFDM symbols, several hours, several minutes, several seconds, several milliseconds (ms), multiple partial OFDM symbols, multiple OOK symbols, multiple OOK time units, or several fractions of a millisecond time unit. A radio frame can include multiple subframes, a subframe can include one or more slots, and a slot can include at least one OFDM symbol. Alternatively, a radio frame can include multiple slots, and a slot can include at least one OFDM symbol. For ease of distinction, in this embodiment, the time unit mapped by OOK modulation is called an OOK time unit, and an OFDM symbol may include one or more OOK time units. For ON mode, the OOK time unit is also called an OOK ON time unit. An OOK time unit can also be referred to as an OOK symbol.

[0227] 2. SSB: In 5G NR communication systems, SSB is a special signal block that contains key signals used for synchronization between network devices and terminals.

[0228] Figure 3 is a schematic diagram of the time-frequency structure of SSB.

[0229] As shown in Figure 3, the SSB can include three parts: the primary synchronization signal (PSS), the secondary synchronization signal (SSS), and the physical broadcast channel (PBCH). The PSS, SSS, and PBCH occupy 127 (obtained from 182-56+1), 127 (obtained from 182-56+1), and 576 (obtained from (239+1)+(47+1)+(239-192+1)+(239+1)) subcarriers, respectively. The main function of the PSS and SSS is to help the terminal maintain synchronization with the network equipment in time and frequency.

[0230] In actual communication, network devices can periodically send SSBs (Signal Subsequent Signals) to enable terminals to synchronize at any point in time. For terminals, they can receive SSBs at fixed, known transmission times according to their own needs to ensure synchronization performance with other signals / channels. Additionally, terminals can use SSB reception for measurement to obtain signal quality information.

[0231] 3. Wake-up Radio: Wake-up radio can be understood as a function that reduces the power consumption of the terminal. For the terminal, wake-up radio refers to the introduction of a low-power (LP) interface on the basis of traditional MR. This LP interface can be implemented through a simple circuit or chip with low power consumption. The specific form of the LP interface is not limited in the embodiments of this application. For example, the LP interface can be implemented through WUR, low-power wake-up receiver (LP-WUR), LR, wake-up module, or wake-up circuit. In this application, WUR can refer to wake-up radio or wake-up receiver. WUR in this document is interchangeable with LP-WUR, LR, wake-up module, or wake-up circuit.

[0232] The MR (Mobile Receiver) can be used for sending and / or receiving data / signaling. If there is no need for sending and / or receiving data / signaling, the MR can be turned off or put into a sleep state or sleep mode. The WUR (Wake-up Receiver) can be used to wake up the MR in a sleep state, for example, when there is a need for sending and / or receiving data / signaling, the WUR wakes up the MR. This design can reduce the power consumption of the terminal.

[0233] The signal received via WUR can be referred to as a low-power signal or LP-WUS, etc. When the terminal detects / receives a low-power signal or LP-WUS, it can wake up the MR in a sleep state. For ease of description, this application uses a low-power signal as an example.

[0234] Understandably, the introduction of LP-WUR is intended to achieve energy saving in the terminal. More specifically, after the introduction of LP-WUR, the terminal can keep LP-WUR active most of the time to complete necessary processes, while MR or currently known high-power receivers can remain in sleep mode most of the time, thereby achieving energy saving in the terminal. For example, the LP-WUR workflow can be shown in Figure 4.

[0235] Figure 4 is a schematic diagram of the LP-WUR workflow.

[0236] After the terminal is powered on, the LP-WUR can remain in a wake-up state (or, in other words, the LP-WUR can remain in an on state), while the MR can remain in a sleep state by default. When the MR needs to be woken up, the LP-WUR can wake it up; otherwise, the MR can remain in a sleep state.

[0237] By way of example and not limitation, LP-WUR can be used to receive low-power signals or low-power wake-up signals (LP-WUS). It is understood that in this application, low-power signals and LP-WUS can be used interchangeably. For ease of description, low-power signals will be used as examples in the following text.

[0238] When the terminal is in the radio resource control (RRC) idle / inactive state, low-power signals can be used to indicate whether there is a paging message.

[0239] For ease of description, the mode that does not monitor low-power signals is referred to as the first operating mode, and the mode that monitors low-power signals is referred to as the second operating mode.

[0240] In this application, the first operating mode (i.e., the mode that does not monitor low-power signals) may include, but is not limited to, one or more of the following: a mode capable of PDCCH transmission; or, a mode capable of PDSCH transmission; or, a mode capable of PUCCH transmission; or, a mode capable of PUSCH transmission; or, a mode with MR enabled; or, a mode with decoding capability; or, a mode capable of transmitting preambles; or, a mode capable of performing random access procedures; or, a mode with demodulation capability.

[0241] In this application, the second operating mode (i.e., the mode for monitoring low-power signals) may include, but is not limited to, one or more of the following: a mode with the LP interface enabled; or a mode with only envelope monitoring capability; or a mode with only correlation monitoring capability; or a mode with only sequence monitoring capability; or a mode with only correlation and envelope monitoring capabilities; or a mode with only the RF front-end enabled; or a mode with the baseband disabled; or a mode capable of receiving PDCCH, etc. The LR interface is implemented using a simple circuit or chip, resulting in low power consumption. The specific form of the LP interface is not limited in this application. For example, the LP interface can be implemented using a WUR, LP-WUR, LR, a wake-up module, or a wake-up circuit.

[0242] In this application, WUR can refer to a wake-up radio or a wake-up receiver. WUR in this application is interchangeable with LP-WUR, LR, wake-up module, or wake-up circuit.

[0243] As an example, and not a limitation, whether a terminal enters (or activates or enables) the second operating mode when it is in the RRC idle / inactive state may depend on channel quality. For example, the network device may configure a first channel measurement threshold for MR. If the channel measurement result of MR is greater than or equal to the first channel measurement threshold, the terminal may enter the second operating mode. As another example, the network device may configure a first channel measurement threshold for MR and a second channel measurement threshold for LP-WUR. If the channel measurement result of MR is greater than or equal to the first channel measurement threshold, and the channel measurement result of LP-WUR is greater than or equal to the second channel measurement threshold, the terminal may enter the second operating mode.

[0244] When the terminal is in RRC connected state, the low power signal can be used to indicate whether there is subsequent PDCCH transmission or data service transmission.

[0245] Figure 5 is a schematic diagram of the low-power signal activation of MR in the RRC connected state.

[0246] The terminal can monitor low-power signals at a location where low-power signals are monitored. Upon detecting a low-power signal, it activates (or wakes up or enables) the MR (Medium-Range Detection) function, enabling the MR to monitor the PDCCH (Programmable Channel Control). During the MR's monitoring of the PDCCH, the LP-WUR (Limited-Power Detection and Control) function does not monitor low-power signals. As shown in Figure 5, intervals 1, 2, and 3 can all be indicated by the same indication information, or they can be indicated by different indication information, or they can be pre-configured or pre-defined; this application does not impose any limitations on this.

[0247] When the terminal is in RRC connection mode, the conditions for the terminal to enter (or activate or enable) may include one or more of the following:

[0248] 1) Signaling indication. For example, layer 1 (L1) / layer 2 (L2) signaling indication can be used. During PDCCH monitoring, if the terminal receives an L1 / L2 signaling indication from the network device to stop monitoring the PDCCH, the terminal can enable (or activate or wake up) LP-WUR and enter the second working mode to monitor low-power signals on the time-frequency resources for monitoring low-power signals.

[0249] 2) Timer control. A timer can be set, during which the terminal can monitor the PDCCH. After the timer expires, it can stop monitoring the PDCCH and enable (or activate or wake up) the LP-WUR to enter the second working mode, where it monitors low-power signals on the time-frequency resources for monitoring low-power signals.

[0250] As an example and not a limitation, if there is uplink data to be transmitted when the terminal is in the second working mode, the terminal can deactivate / exit the second working mode, enter (or enable or activate) the first working mode, wake up (or enable) MR, and perform uplink or downlink data / information transmission, or perform PDCCH monitoring.

[0251] 4. Low-power signals: Low-power signals can be low-power PDCCH, low-power physical downlink shared channel (PDSCH), low-power physical uplink shared channel (PUSCH), low-power physical uplink control channel (PUCCH), low-power (LP) synchronization signal block (SSB) (LP-SS), low-power synchronization signal / physical broadcast channel block (SSB), low-power tracking reference signal (TRS), low-power channel status information reference signal (CSI-RS), low-power positioning signal, low-power sensing communication signal, low-power sounding reference signal (SRS), low-power random access channel (RACH), low-power preamble, low-power contention resolution message, low-power downlink control information (DCI), or low-power uplink control information (UCI), etc.

[0252] 5. Low-Power Synchronization Signal (LP-SS): Similar to SSB, LP-SS can be used for UE synchronization and measurement. LP-SS was introduced for Low-Power Wake-up Receiver (LP-WUR) (also known as Low-Power Receiver). Receiving SSB consumes a lot of power, so a low-complexity signal LP-SS was designed. LP-WUR can receive LP-SS for synchronization and measurement.

[0253] 6. SPS: Unlike dynamic scheduling, which allocates radio resources to a terminal once per transmission time interval (TTI), SPS allows for semi-static configuration of radio resources, periodically allocating these resources to a specific terminal. Because SPS features "allocate once, use many times," all periodically configured resources only need to be activated by sending a DCI once, eliminating the need to send a DCI to the terminal in every TTI, thus reducing the corresponding PDCCH overhead.

[0254] Specifically, for downlink, after receiving the SPS configuration information (SPS-config), the terminal cannot use it immediately; it must activate it using a PDCCH scrambled with configured scheduling (CS)-RNTI (CS-RNTI). Network devices can activate / deactivate the terminal's SPS using a CS-RNTI scrambled PDCCH. The terminal will only verify whether the received PDCCH is used for SPS activation or deactivation if the following conditions are met:

[0255] 1) The cyclic redundancy check (CRC) bits of PDCCH are scrambled using CS-RNTI;

[0256] 2) The New Data Indicator (NDI) field is set to 0. For DCI format 2 / 2A / 2B / 2C, the NDI field refers to the enabled transport block (TB).

[0257] If downlink SPS is configured and activated, the terminal will assume that downlink SPS resources have been allocated in a subframe (called an SPS subframe) that satisfies the following formula (at which point PDCCH is not required): (numberOfSlotsPerFrame × SFN + slot number in the frame) = [(numberOfSlotsPerFrame × SFNstart time + slotstart time) + N × periodicity × numberOfSlotsPerFrame / 10] modulo (1024 × numberOfSlotsPerFrame). Wherein, SFNstart time and Slotstart time are the system frame number (SFN) and slot number of the first Physical Downlink Shared Channel (PDSCH) transmission after the downlink SPS is activated by the PDCCH scrambled by CS-RNTI, respectively; N > 0 (initially 0, incremented by 1 every cycle).

[0258] Figure 6 is a schematic diagram of SPS resources.

[0259] As shown in Figure 6, SPS resources are periodic.

[0260] 7. CG: For uplink, semi-static scheduling resources can be called configuration scheduling (CG). Downlink can activate SPS through a DCI in a PDCCH, and similarly, uplink can activate CG through a DCI in a PDCCH (CG Type 2). Additionally, uplink CG can also take effect directly after configuration without activation (CG Type 1). That is, if network devices can configure the terminal to periodically send the radio resources used through higher-layer signaling, the terminal, upon receiving the configuration, can transmit data on the configured radio resources.

[0261] 8. Enabling: Enabling a mode or feature can be understood as giving network devices and / or terminal devices the ability to enter a certain mode or apply a certain feature. However, it does not mean that network devices and / or terminal devices will immediately enter a certain mode or apply a certain feature after enabling. In some scenarios, enabling can be understood as being configured.

[0262] 9. Disable: Disabling a mode or feature can be understood as the network device and / or terminal device no longer having the ability to enter a certain mode or apply a certain feature, or the network device and / or terminal device no longer entering a certain mode or applying a certain feature. In some scenarios, disabling can be understood as not being configured.

[0263] 10. Activation: Activation is premised on the fact that a certain mode or feature is already enabled. It is assumed to be activated by default, or further operations are required to enter a certain mode or apply a certain feature.

[0264] 11. Deactivation: Deactivating a mode or feature does not necessarily mean enabling that mode or disabling the ability to apply that feature. It simply means temporarily disabling that mode or feature. When certain conditions are met (signaling trigger, timer expiration trigger, or specific information transmission requirements), the terminal can reactivate that mode or feature.

[0265] 12. Configured: This indicates that the network has configured relevant configuration information through the indication information, and the terminal device has confirmed the relevant configuration information upon receiving the indication information. "Configured" can be understood as being enabled, activated, or tripped up.

[0266] 13. Not Configured: This indicates that the network has not configured the relevant configuration information in any way, and the terminal has not received any relevant configuration information. For the terminal, if it has not been configured, the terminal will not enable the configuration-related features, or the terminal will not enter the configuration-related mode, or the terminal will not have the ability to enter the configuration-related mode or apply the configuration-related features.

[0267] 14. The first signal can be understood as a low-power signal, a signal with a simple modulation method, or a signal with a simple encoding method.

[0268] 15. The encoding method of the first signal or low-power signal can be Manchester encoding or RM encoding, or the first signal or low-power signal needs to be rate matched.

[0269] 16. The modulation method of the first signal is one or more of the following: on-key modulation, sequence modulation, phase modulation, ZC sequence carrying, or frequency shift keying modulation.

[0270] It should be noted that the various embodiments shown below can be deployed individually or in combination.

[0271] With the development of communication technology, people have increasingly higher requirements for power consumption and latency. In current mobile communication systems, terminals need to be woken up periodically once per DRX cycle. When the terminal is in a wake-up state, but there is no signaling or data service transmission during the wake-up period, the terminal is in an invalid wake-up state, and the power consumption during this period accounts for the main proportion of the terminal's overall power consumption. If the terminal is only woken up when signaling or data services need to be transmitted, such as receiving paging messages, the terminal's power consumption can be significantly reduced. However, in some scenarios with high latency requirements, it is necessary to support low power consumption mechanisms while ensuring low latency.

[0272] In one known communication method, higher energy efficiency is achieved by triggering MR wake-up using a low-power wake-up signal. When MR is enabled, it can be used for data transmission and reception; when disabled or in sleep mode, a separate receiver (e.g., LP-WUR) with ultra-low power monitoring wake-up signal capability receives signals, resulting in extremely low power consumption.

[0273] However, in the above communication method, the terminal sometimes misses the PDCCH activated by the low power signal, resulting in information transmission delay; but sometimes it will continuously monitor whether there is a PDCCH, resulting in high power consumption, especially when the time domain resources for monitoring the low power signal overlap with the MR wake-up period (i.e. the period when the terminal is in the wake-up process) or the MR monitoring PDCCH period.

[0274] To address the aforementioned technical issues, firstly, by comprehensively considering the positional relationship between the time-domain resources for monitoring the PDCCH, the time-domain resources for monitoring low-power signals, and the configured periodic resources, the location for monitoring the PDCCH or entering the low-power signal monitoring mode can be determined. Thus, the terminal can clearly identify the location for monitoring the PDCCH or the location for entering the low-power signal monitoring mode.

[0275] The communication method provided in this application will now be described in detail with reference to the accompanying drawings.

[0276] Figure 7 is a schematic flowchart of a communication method 700 (which can be referred to as communication method one for ease of description) provided in an embodiment of this application. The steps of method 700 are described in detail below.

[0277] The method is described in method 700 using the interaction between the first communication device and the second communication device as an example, and should not be construed as limiting the scope of this application.

[0278] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or system-on-chip (SoC) chips or system-in-package (SIP) chips containing modem cores), chip systems, or processors, etc.), and this application does not limit it in this regard.

[0279] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0280] The following description uses the first communication device as the terminal and the second communication device as a network device as an example to illustrate the communication method 2100 provided in this application.

[0281] In step 710, the network device determines the time-domain resources for transmitting low-power signals.

[0282] Accordingly, in step 720, the terminal determines the time-domain resources for monitoring low-power signals.

[0283] It is understandable that network devices can determine the time-domain resources for transmitting low-power signals, and correspondingly, terminals can also determine the time-domain resources for monitoring low-power signals.

[0284] In one possible implementation, the time-frequency resources (or time location) for the network device to transmit low-power signals can be determined based on the time-frequency resources (or time location or opportunity) for transmitting paging messages (PO). Correspondingly, the time-frequency resources (or time location) for the terminal to monitor low-power signals can be determined based on the time-frequency resources (or time location or opportunity) for monitoring paging messages (PO). After detecting a low-power signal carrying terminal information on the time-frequency resources for monitoring low-power signals, the terminal can monitor the paging message at the corresponding PO.

[0285] Optionally, the PO can be used as a reference point, and the network device can configure the interval between the PO and the time-frequency resources for monitoring low-power signals.

[0286] The terminal can monitor one PO within each DRX cycle. A PO can be a set of monitoring occasions (MOs) for PDCCHs. As an example and not a limitation, the PO can be determined based on the following formulas 1 and 2:

[0287] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) (For ease of description, this formula is referred to as Formula 1 in this application), where PF_offset can represent the offset (amount) used to determine the paging frame (PF), and PF_offset can be configured by RRC signaling. PF can contain one or more POs or radio frames from the PO origin; T can represent the paging period (length); N can represent the number of PFs in a paging period T, and T can be configured by RRC signaling; UE_ID satisfies: UE_ID=5G-S-TMSI mod1024; SFN can represent the system frame number.

[0288] After determining the PF that needs to be sent during the paging cycle, the network device can also determine the identifier i_s of the PO that needs to be sent. Correspondingly, after determining the PF that needs to be monitored during the paging cycle, the terminal can also determine the identifier i_s of the PO that needs to be monitored.

[0289] As an example and not a limitation, the identifier i_s of a PO can satisfy the following formula: i_s = floor(UE_ID / N) mod Ns. For ease of description, this formula is referred to as Formula 2 in this application, where UE_ID satisfies: UE_ID = 5G-S-TMSI mod 1024; N can represent the number of PFs in a paging cycle T, and T can be configured by RRC signaling; Ns can represent the number of POs in a PF, and Ns can be configured by RRC signaling.

[0290] Optionally, the time-domain resources for transmitting the low-power signal are continuous. Accordingly, the time-domain resources for monitoring the low-power signal are continuous.

[0291] In one possible design, the time-domain resource for transmitting the low-power signal is a contiguous block of time-domain resources. Correspondingly, the time-domain resource for monitoring the low-power signal is also a contiguous block of time-domain resources.

[0292] In another possible design, the time-domain resources for transmitting low-power signals are composed of multiple overlapping time-domain resource blocks. Correspondingly, the time-domain resources for monitoring low-power signals are also composed of multiple overlapping time-domain resource blocks.

[0293] Optionally, the low-power signal transmitted in the time-domain resource transmitting the low-power signal is used to indicate whether there is PDCCH transmission in the time-domain resource transmitting the PDCCH. Correspondingly, the low-power signal transmitted in the time-domain resource monitoring the low-power signal is used to indicate whether there is PDCCH transmission in the time-domain resource monitoring the PDCCH.

[0294] As mentioned in the terminology section above, when the terminal is in RRC connected state, the low-power signal can be used to indicate whether there is subsequent PDCCH transmission or data service transmission. In this alternative mode, the low-power signal transmitted on the time-domain resource monitoring the low-power signal can be used to indicate whether there is PDCCH transmission on the time-domain resource monitoring the PDCCH.

[0295] It is understood that this application does not limit the execution order of steps 710 and 720. For example, step 710 may be executed before step 720, or step 710 may be executed after step 720, or steps 710 and 720 may be executed simultaneously. This application does not limit this in any way.

[0296] In step 730, the network device sends a PDCCH. The time-domain resources for sending the PDCCH are related to the time-domain resources for sending low-power signals and a first condition, which includes configuring periodic resources for the terminal.

[0297] Accordingly, in step 740, the terminal monitors the PDCCH. The time-domain resources for monitoring the PDCCH are related to the time-domain resources for monitoring low-power signals and a first condition, which includes the terminal being configured with periodic resources.

[0298] Once the identifier i_s of the PO is determined, each PO contains one or more MOs, and each MO corresponds to a different SSB index. After receiving SSBs from multiple beams, the terminal knows which SSB index has the best channel quality and can then monitor the PDCCH at the MO corresponding to that SSB index.

[0299] In one possible implementation, the network device configures periodic resources for the terminal by one or more of the following: activating the terminal's SPS; or activating the terminal's CG; or configuring the terminal's CG. Accordingly, the periodic resources configured for the terminal include one or more of the following: the terminal is activated by SPS; or the terminal is activated by CG; or the terminal is configured by CG.

[0300] In other words, in method 700, the terminal can be activated SPS, and / or the terminal can be activated CG, and / or the terminal can be configured CG.

[0301] For a detailed description of SPS and CG, please refer to the relevant explanations in the terminology section above. For the sake of brevity, they will not be repeated here.

[0302] In one possible implementation A, the time-domain resources for the network device to transmit the PDCCH are related to the time-domain resources for transmitting the low-power signal and a first condition, including: when the time-domain resources for transmitting the low-power signal overlap with the period during which the terminal is in the wake-up process, the interval between the start position of the time-domain resources for transmitting the PDCCH and the start position of the periodic resource is a first interval, and the time-domain resources for transmitting the PDCCH are after the start position of the periodic resource. Correspondingly, the time-domain resources for the terminal to monitor the PDCCH are related to the time-domain resources for monitoring the low-power signal and the first condition, including: when the time-domain resources for monitoring the low-power signal overlap with the period during which the terminal is in the wake-up process, the interval between the start position of the time-domain resources for monitoring the PDCCH and the start position of the periodic resource is a first interval, and the time-domain resources for monitoring the PDCCH are after the start position of the periodic resource. Wherein, the first interval is greater than or equal to 0.

[0303] Figure 8 is a schematic diagram showing the overlap between the time-domain resources for monitoring low-power signals and the time period when the terminal is in the wake-up process.

[0304] As shown in Figures 8a), b), and c), initially, the terminal's MR is in a sleep state. Subsequently, the terminal's MR accumulates enough sleep time to be woken up. During the process of the terminal's MR being woken up (i.e., the period during which the terminal is in the wake-up process), there are time-domain resources for monitoring low-power signals. In other words, the time-domain resources for monitoring low-power signals overlap with the period during which the terminal is in the wake-up process.

[0305] In Figures 8a) and 8b), what is the same is that the time-domain resources for monitoring low-power signals are completely in the process of the terminal's MR being woken up. What is different is that in Figure 8b), at the end of the time-domain resources for monitoring low-power signals, the terminal enters the first working mode.

[0306] In Figure 8c), the terminal has already entered the first working mode before the end of the time domain resource for monitoring low-power signals has been reached.

[0307] In the three cases shown in Figure 8, the interval between the start position of the time-domain resource of the monitored PDCCH and the start position of the periodic resource is the first interval. The time-domain resource of the monitored PDCCH is after the start position of the periodic resource, that is, the time-domain resource of the monitored PDCCH is later than the start position of the periodic resource.

[0308] It is understood that when the first interval is equal to 0, the starting position of the time-domain resource for transmitting the PDCCH is located at the starting position of the periodic resource. Accordingly, when the first interval is equal to 0, the starting position of the time-domain resource for monitoring the PDCCH is located at the starting position of the periodic resource.

[0309] Figure 9 is a schematic diagram of monitoring the time-domain resources of PDCCH.

[0310] For example, as shown in FIG9a), in the three cases shown in FIG8, and when the first interval is equal to 0, the starting position of the time-domain resource of the monitored PDCCH is located at the starting position of the periodic resource. That is, when the first interval is equal to 0, the interval between the starting position of the time-domain resource of the monitored PDCCH and the starting position of the periodic resource is the first interval, which can be replaced by: the starting position of the time-domain resource of the monitored PDCCH is located at the starting position of the periodic resource. That is, when the first interval is equal to 0, the starting position of the time-domain resource of the monitored PDCCH is the same as the starting position of the periodic resource.

[0311] It can also be understood that, when the first interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the periodic resource. Accordingly, when the first interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource for monitoring the PDCCH is located at the end position of the periodic resource.

[0312] For example, as shown in Figure 9b), in the three cases shown in Figure 8, and when the first interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the periodic resource. That is, when the first interval is equal to the length of the periodic resource within the first time range, the interval between the start position of the time-domain resource of the monitoring PDCCH and the start position of the periodic resource is the first interval, which can be replaced by: the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the periodic resource.

[0313] Understandably, if only one time-domain resource for monitoring low-power signals overlaps with the period during which the terminal is in the wake-up process, the interval between the start position of the time-domain resource for monitoring PDCCH and the start position of the first periodic resource after the end position of the time-domain resource for monitoring low-power signals is the first interval; if multiple time-domain resources for monitoring low-power signals overlap with the period during which the terminal is in the wake-up process, the interval between the start position of the time-domain resource for monitoring PDCCH and the start position of the first periodic resource after the end position of the last time-domain resource for monitoring low-power signals among the multiple time-domain resources for monitoring low-power signals is the first interval.

[0314] In one possible implementation B, the time-domain resources for the network device to transmit the PDCCH are related to the time-domain resources for transmitting the low-power signal and a first condition, including: when the time-domain resources for transmitting the low-power signal overlap with the time period during which the terminal is in the wake-up process, the interval between the start position and the end position of the time-domain resources for transmitting the PDCCH is a second interval, the time-domain resources for transmitting the PDCCH are after the end position of the time-domain resources for transmitting the low-power signal, and the terminal is in a first operating mode at the start position of the time-domain resources for transmitting the PDCCH. Accordingly, the time-domain resources for terminal monitoring of PDCCH are related to the time-domain resources for monitoring low-power signals and the first condition, including: when the time-domain resources for monitoring low-power signals overlap with the period when the terminal is in the wake-up process, the interval between the start position and the end position of the time-domain resources for monitoring PDCCH is a second interval; the time-domain resources for monitoring PDCCH are after the end position of the time-domain resources for monitoring low-power signals; and the terminal is in a first operating mode at the start position of the time-domain resources for monitoring PDCCH. The first operating mode is a mode in which low-power signals are not monitored, and the second interval is greater than or equal to 0.

[0315] As described above regarding Figure 8, in Figure 8b), the terminal enters the first operating mode at the end of the time-domain resource for monitoring the low-power signal; while in Figure 8c), the terminal enters the first operating mode before reaching the end of the time-domain resource for monitoring the low-power signal. Therefore, Figures 8b) and c) apply to method B. In other words, in the two cases shown in Figure 8b) and c), the interval between the start position of the time-domain resource for monitoring the PDCCH and the end position of the time-domain resource for monitoring the low-power signal is the second interval. The time-domain resource for monitoring the PDCCH is after the end position of the time-domain resource for monitoring the low-power signal, that is, the time-domain resource for monitoring the PDCCH is later than the end position of the time-domain resource for monitoring the low-power signal.

[0316] Figure 10 is another schematic diagram of monitoring the time-domain resources of PDCCH.

[0317] In Figure 10, a) in Figure 10 corresponds to b) in Figure 8, and b) in Figure 10 corresponds to c) in Figure 8.

[0318] It is understood that when the second interval is equal to 0, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the time-domain resource for transmitting the low-power signal. Correspondingly, when the second interval is equal to 0, the start position of the time-domain resource for monitoring the PDCCH is located at the end position of the time-domain resource for monitoring the low-power signal.

[0319] For example, as shown in a) or b) of FIG10, when the second interval is equal to 0, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal. That is, when the second interval is equal to 0, the interval between the start position of the time-domain resource of the monitoring PDCCH and the end position of the time-domain resource of the monitoring low-power signal is the second interval, which can be replaced by: the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal.

[0320] Optionally, in either method A or method B above, the terminal being in the wake-up process is the process by which the terminal is woken up to transmit information on the periodic resource. The terminal being in the wake-up process can also be understood as the terminal's MR being woken up, and the MR being woken up is for the purpose of transmitting data or signaling on the periodic resource.

[0321] In one possible implementation C, the time-domain resources for the network device to transmit the PDCCH are related to the time-domain resources for transmitting the low-power signal and a first condition, including: when the time-domain resources for transmitting the low-power signal overlap with the periodic resource, the interval between the start position of the time-domain resources for transmitting the PDCCH and the start position of the periodic resource is a third interval, and the time-domain resources for transmitting the PDCCH are after the start position of the periodic resource. Correspondingly, the time-domain resources for the terminal to monitor the PDCCH are related to the time-domain resources for monitoring the low-power signal and the first condition, including: when the time-domain resources and / or frequency-domain resources for monitoring the low-power signal overlap with the periodic resource, the interval between the start position of the time-domain resources for monitoring the PDCCH and the start position of the periodic resource is a third interval, and the time-domain resources for monitoring the PDCCH are after the start position of the periodic resource. Wherein, the third interval is greater than 0.

[0322] Figure 11 is a schematic diagram of the overlap between time-domain resources and periodic resources for monitoring low-power signals.

[0323] As shown in Figures 11a), b), and c), initially, the terminal's MR is in a sleep state. Subsequent terminals' MRs accumulate enough data to reach a sleep state and are then awakened. After the terminal's MR is awakened, it can transmit data or signaling on periodic resources. However, when periodic resources are enabled, the time-domain and / or frequency-domain resources for monitoring low-power signals may overlap with the periodic resources. As shown in Figure 11a), the monitoring of low-power signals is entirely within the periodic resources; as shown in Figures 11b) and c), the monitoring of low-power signals is not entirely within the periodic resources.

[0324] For example, in the three cases shown in Figure 11, the interval between the start position of the time-domain resource of the monitored PDCCH and the start position of the periodic resource is the third interval. The time-domain resource of the monitored PDCCH is after the start position of the periodic resource, that is, the time-domain resource of the monitored PDCCH is later than the start position of the periodic resource.

[0325] It is understood that when the third interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the periodic resource. Correspondingly, when the third interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource for monitoring the PDCCH is located at the end position of the periodic resource.

[0326] The first time frame can be understood as a periodic resource allocation cycle.

[0327] Figure 12 is another schematic diagram of monitoring the time-domain resources of PDCCH.

[0328] As shown in Figure 12, in the three cases shown in Figure 11, and when the third interval is equal to the length of the periodic resource within the first time range, the start position of the time-domain resource of the monitored PDCCH is located at the end position of the periodic resource. That is, when the third interval is equal to the length of the periodic resource within the first time range, the interval between the start position of the time-domain resource of the monitored PDCCH and the start position of the periodic resource is the third interval, which can be replaced by: the start position of the time-domain resource of the monitored PDCCH is located at the end position of the periodic resource.

[0329] In one possible implementation D, the time-domain resources for the network device to transmit the PDCCH are related to the time-domain resources for transmitting the low-power signal and a first condition, including: when the time-domain resources for transmitting the low-power signal overlap with the periodic resource, the interval between the start position and the end position of the time-domain resources for transmitting the PDCCH is a fourth interval, and the time-domain resources for transmitting the PDCCH are after the end position of the time-domain resources for transmitting the low-power signal. Correspondingly, the time-domain resources for the terminal to monitor the PDCCH are related to the time-domain resources for monitoring the low-power signal and the first condition, including: when the time-domain resources for monitoring the low-power signal overlap with the periodic resource, the interval between the start position and the end position of the time-domain resources for monitoring the PDCCH is a fourth interval, and the time-domain resources for monitoring the PDCCH are after the end position of the time-domain resources for monitoring the low-power signal. Wherein, the fourth interval is greater than or equal to 0.

[0330] For example, in the three cases shown in FIG11, the interval between the start position of the time domain resource of the monitoring PDCCH and the end position of the time domain resource of the monitoring low power signal is the fourth interval, and the time domain resource of the monitoring PDCCH is after the end position of the time domain resource of the monitoring low power signal, that is, the time domain resource of the monitoring PDCCH is later than the end position of the time domain resource of the monitoring low power signal.

[0331] It is understood that when the fourth interval is equal to 0, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the time-domain resource for transmitting the low-power signal. Accordingly, when the fourth interval is equal to 0, the start position of the time-domain resource for monitoring the PDCCH is located at the end position of the time-domain resource for monitoring the low-power signal.

[0332] Figure 13 is another schematic diagram of monitoring the time-domain resources of PDCCH.

[0333] In Figure 13, a) of Figure 13 corresponds to a) of Figure 11, b) of Figure 13 corresponds to b) of Figure 11, and c) of Figure 13 corresponds to c) of Figure 11.

[0334] For example, as shown in a), b), or c) of FIG13, when the fourth interval is equal to 0, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal. That is, when the fourth interval is equal to 0, the interval between the start position of the time-domain resource of the monitoring PDCCH and the end position of the time-domain resource of the monitoring low-power signal is the fourth interval, which can be replaced by: the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal.

[0335] Based on this method 700, for a terminal, when periodic resources are configured, by comprehensively considering the positional relationship between the time-domain resources for monitoring the PDCCH, the time-domain resources for monitoring low-power signals, and the configured periodic resources, the location for monitoring the PDCCH or entering the low-power signal monitoring mode can be determined. Thus, the terminal can clearly define the location for monitoring the PDCCH or entering the low-power signal monitoring mode. Furthermore, it can meet the needs of terminals with different energy-saving or latency requirements, which is beneficial for terminal energy saving or ensuring service capacity.

[0336] For network devices, when configuring periodic resources for terminals, the location for transmitting the PDCCH is determined by comprehensively considering the temporal relationship between the time-domain resources for monitoring the PDCCH, the time-domain resources for transmitting low-power signals, and the periodic resources configured for the terminals. This allows network devices to clearly define the location for transmitting the PDCCH, which is beneficial for energy saving.

[0337] Figure 14 is a schematic flowchart of a communication method 1400 (which can be referred to as communication method two for ease of description) provided in an embodiment of this application. The steps of method 1400 are described in detail below.

[0338] The method is described in method 1400 using the interaction between a first communication device and a second communication device as an example, and should not be construed as limiting the scope of this application.

[0339] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIPs containing modem cores), chip systems, or processors, etc.). This application does not limit the scope of the application.

[0340] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0341] The following description uses the first communication device as the terminal and the second communication device as a network device as an example to illustrate the communication method 2100 provided in this application.

[0342] In step 1410, the network device determines the time-domain resources for transmitting low-power signals.

[0343] Accordingly, in step 1420, the terminal determines the time-domain resources for monitoring low-power signals.

[0344] It is understandable that network devices can determine the time-domain resources for transmitting low-power signals, and correspondingly, terminals can also determine the time-domain resources for monitoring low-power signals.

[0345] For a detailed description of steps 1410 and 1420, please refer to the relevant descriptions of steps 710 and 720 above. For the sake of brevity, they will not be repeated here.

[0346] Optionally, the time-domain resources for transmitting the low-power signal are continuous. Accordingly, the time-domain resources for monitoring the low-power signal are continuous.

[0347] In one possible design, the time-domain resource for transmitting the low-power signal is a contiguous block of time-domain resources. Correspondingly, the time-domain resource for monitoring the low-power signal is also a contiguous block of time-domain resources.

[0348] In another possible design, the time-domain resources for transmitting low-power signals are composed of multiple overlapping time-domain resource blocks. Correspondingly, the time-domain resources for monitoring low-power signals are also composed of multiple overlapping time-domain resource blocks.

[0349] Optionally, the low-power signal transmitted in the time-domain resource transmitting the low-power signal is used to indicate whether there is PDCCH transmission in the time-domain resource transmitting the PDCCH. Correspondingly, the low-power signal transmitted in the time-domain resource monitoring the low-power signal is used to indicate whether there is PDCCH transmission in the time-domain resource monitoring the PDCCH.

[0350] As mentioned in the terminology section above, when the terminal is in RRC connected state, the low-power signal can be used to indicate whether there is subsequent PDCCH transmission or data service transmission. In this alternative mode, the low-power signal transmitted on the time-domain resource monitoring the low-power signal can be used to indicate whether there is PDCCH transmission on the time-domain resource monitoring the PDCCH.

[0351] It is understood that this application does not limit the execution order of steps 1410 and 1420. For example, step 1410 may be executed before step 1420, or step 1410 may be executed after step 1420, or steps 1410 and 1420 may be executed simultaneously. This application does not limit this in any way.

[0352] In step 1430, the network device sends a PDCCH. When the time domain resource for sending low-power signals overlaps with the time period when the terminal is in the wake-up process, the interval between the start position of the time domain resource for sending PDCCH and the end position of the time domain resource for sending low-power signals is the fifth interval. The time domain resource for sending PDCCH is after the end position of the time domain resource for sending low-power signals, and the terminal is in the first working mode at the start position of the time domain resource for sending PDCCH.

[0353] Accordingly, in step 1440, the terminal monitors the PDCCH. When the time domain resources for monitoring low-power signals overlap with the time period during which the terminal is in the wake-up process, the interval between the start position of the time domain resources for monitoring the PDCCH and the end position of the time domain resources for monitoring low-power signals is the fifth interval. The time domain resources for monitoring the PDCCH are after the end position of the time domain resources for monitoring low-power signals, and the terminal is in the first working mode at the start position of the time domain resources for monitoring the PDCCH.

[0354] The first operating mode is one that does not monitor low-power signals. The fifth interval is greater than or equal to 0.

[0355] As mentioned above, Figure 8 is a schematic diagram showing the overlap between the time-domain resources for monitoring low-power signals and the time period during which the terminal is in the wake-up process. For a detailed description of the overlap between the time-domain resources for monitoring low-power signals and the time period during which the terminal is in the wake-up process, please refer to the relevant description of Figure 8 above. For the sake of brevity, it will not be repeated here.

[0356] As described above regarding Figure 8, in Figure 8b), the terminal enters the first operating mode at the end of the time-domain resource for monitoring the low-power signal; while in Figure 8c), the terminal enters the first operating mode before reaching the end of the time-domain resource for monitoring the low-power signal. Therefore, Figures 8b) and c) apply to step 1420 of method 1400. In other words, in both cases shown in Figure 8b) and c), the interval between the start position of the time-domain resource for monitoring the PDCCH and the end position of the time-domain resource for monitoring the low-power signal is a fifth interval. The time-domain resource for monitoring the PDCCH is after the end position of the time-domain resource for monitoring the low-power signal, that is, the time-domain resource for monitoring the PDCCH is later than the end position of the time-domain resource for monitoring the low-power signal.

[0357] It is understood that when the fifth interval is equal to 0, the start position of the time-domain resource for transmitting the PDCCH is located at the end position of the time-domain resource for transmitting the low-power signal. Correspondingly, when the fifth interval is equal to 0, the start position of the time-domain resource for monitoring the PDCCH is located at the end position of the time-domain resource for monitoring the low-power signal.

[0358] For example, as shown in a) or b) of FIG10, when the fifth interval is equal to 0, the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal. That is, when the fifth interval is equal to 0, the interval between the start position of the time-domain resource of the monitoring PDCCH and the end position of the time-domain resource of the monitoring low-power signal is the fifth interval, which can be replaced by: the start position of the time-domain resource of the monitoring PDCCH is located at the end position of the time-domain resource of the monitoring low-power signal.

[0359] Optionally, the terminal being in the wake-up process is the process by which the terminal is woken up to transmit information on the periodic resource. The terminal being in the wake-up process can also be understood as the terminal's MR being woken up, and the terminal's MR being woken up is for the purpose of transmitting data or signaling on the periodic resource.

[0360] Based on this method 1400, for the terminal, by specifying the monitoring location (or time domain resource) of the PDCCH under different conditions, the terminal can align the monitoring location (or time domain resource) of the PDCCH with the network device. The terminal can then clearly specify the location for monitoring the PDCCH or the location for entering the low-power signal monitoring mode. In addition, it can also meet the different energy-saving or latency requirements of terminals, which is beneficial for terminal energy saving or ensuring service capacity.

[0361] For network devices, by specifying the PDCCH transmission location (or time domain resource) under different circumstances, the network device can align the PDCCH transmission location (or time domain resource) with the terminal. Furthermore, the network device can send the PDCCH in advance, which helps reduce service transmission latency. Additionally, the ability to specify the PDCCH transmission location is beneficial for network device energy saving.

[0362] To address the aforementioned technical issues, secondly, the timing of the terminal entering the second operating mode is determined by comprehensively considering at least two of the following: time-domain resources for monitoring low-power signals, channel measurement results of the terminal, and indication information indicating entry into the second operating mode or entry into the second operating mode after a timer stops. Thus, the terminal can clearly determine the time to enter the second operating mode.

[0363] Figure 15 is a schematic flowchart of a communication method 1500 (which can be referred to as communication method three for ease of description) provided in an embodiment of this application. The steps of method 1500 are described in detail below.

[0364] The method is described in method 1500 using the interaction between a first communication device and a second communication device as an example, and should not be construed as limiting the scope of this application.

[0365] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIPs containing modem cores), chip systems, or processors, etc.). This application does not limit the scope of the application.

[0366] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0367] The following description uses the first communication device as the terminal and the second communication device as a network device as an example to illustrate the communication method 2100 provided in this application.

[0368] In step 1510, the network device determines the time-domain resources for transmitting low-power signals.

[0369] Accordingly, in step 1420, the terminal determines the time-domain resources for monitoring low-power signals.

[0370] It is understandable that network devices can determine the time-domain resources for transmitting low-power signals, and correspondingly, terminals can also determine the time-domain resources for monitoring low-power signals.

[0371] For a detailed description of steps 1510 and 1520, please refer to the relevant descriptions of steps 710 and 720 above. For the sake of brevity, they will not be repeated here.

[0372] Optionally, the low-power signal transmitted in the time-domain resource transmitting the low-power signal is used to indicate whether there is PDCCH transmission in the time-domain resource transmitting the PDCCH. Correspondingly, the low-power signal transmitted in the time-domain resource monitoring the low-power signal is used to indicate whether there is PDCCH transmission at a first time.

[0373] As mentioned in the terminology section above, when the terminal is in RRC connected state, the low-power signal can be used to indicate whether there is subsequent PDCCH transmission or data service transmission. In this alternative approach, the low-power signal used for monitoring time-domain resource transmission of the low-power signal can be used to indicate whether there is PDCCH transmission at a first opportune moment.

[0374] In one possible implementation, the time-domain resources and / or frequency-domain resources for transmitting the low-power signal overlap with the time period during which the terminal is in a first operating mode, which is a mode in which low-power signals are not monitored. Correspondingly, the time-domain resources and / or frequency-domain resources for monitoring the low-power signal overlap with the time period during which the terminal is in the first operating mode, which is a mode in which low-power signals are not monitored.

[0375] In other words, the time-domain and / or frequency-domain resources for monitoring low-power signals overlap with the time periods when the terminal is not monitoring low-power signals.

[0376] As mentioned in the terminology section above, the first operating mode (i.e., the mode in which low-power signals are not monitored) may include, but is not limited to, one or more of the following: a mode for transmitting PDCCH; or, a mode for transmitting PDSCH; or, a mode for transmitting PUCCH; or, a mode for transmitting PUSCH; or, a mode in which MR is enabled.

[0377] In step 1530, the terminal and network device determine the moment when the terminal enters the second operating mode.

[0378] The second operating mode is a mode for monitoring low-power signals.

[0379] For network devices, the time at which a terminal enters the second operating mode is related to at least two of the following: the time-domain resources for transmitting low-power signals; or a second condition, the second condition including a channel measurement result of the terminal being greater than or equal to a threshold; or a third condition, the third condition including transmitting indication information for instructing the terminal to enter the second operating mode; or a first timer stopping, the length of the first timer being the duration for which the terminal monitors the physical downlink control channel (PDCCH).

[0380] Accordingly, for network devices, the time at which a terminal enters the second operating mode is related to at least two of the following: the time-domain resources for monitoring low-power signals; or, a second condition including the terminal's channel measurement result being greater than or equal to a threshold; or, a third condition including receiving indication information for instructing the terminal to enter the second operating mode; or, a first timer stopping, the length of which is the duration for which the terminal monitors the PDCCH.

[0381] Regarding the condition "the second condition includes the channel measurement result of the terminal being greater than or equal to the threshold", one example is when configuring one threshold, for example, the network device configures a first channel measurement threshold for MR, and the second condition includes the channel measurement result of MR being greater than or equal to the first channel measurement threshold; another example is when the network device configures a second channel measurement threshold for LP-WUR, and the second condition includes the channel measurement result of LP-WUR being greater than or equal to the second channel measurement threshold; yet another example is when configuring two thresholds, the network device configures a first channel measurement threshold for MR and a second channel measurement threshold for LP-WUR, and the second condition includes the channel measurement result of MR being greater than or equal to the first channel measurement threshold, and the channel measurement result of LP-WUR being greater than or equal to the second channel measurement threshold.

[0382] The phrase “the third condition includes receiving an indication message that instructs the terminal to enter the second operating mode” is, as an example and not a limitation, and the indication message may be indicated by L1 / L2 signaling.

[0383] The length of the first timer is the duration during which the terminal monitors the PDCCH. This can be understood as the terminal monitoring the PDCCH during the operation of the first timer.

[0384] In other words, the terminal can determine the moment to enter the second working mode based on at least two of the above-mentioned factors.

[0385] In one possible implementation, for the network device, when the condition is met after the start of the time-domain resource for transmitting the low-power signal and before the first timing: the interval between the time when the terminal enters the second operating mode and the end of the first timing is a sixth interval, and the time when the terminal enters the second operating mode is after the first timing, wherein the sixth interval is greater than or equal to 0; or, the interval between the time when the terminal enters the second operating mode and the time when the condition is met is a seventh interval, the time when the terminal enters the second operating mode is after the time when the condition is met, and the time when the terminal enters the second operating mode is earlier than the start of the first timing, wherein the seventh interval is greater than or equal to 0; wherein the time when the condition is met includes one or more of the following times: the time when the second condition is met, the time when the third condition is met, or the time when the first timer stops. Accordingly, for the terminal, if the time when the condition is met is after the start position of the time domain resource for monitoring low-power signals and before the first timing, the interval between the time of entering the second operating mode and the end position of the first timing is a sixth interval, and the time of entering the second operating mode is after the first timing, wherein the sixth interval is greater than or equal to 0; or, the interval between the time of entering the second operating mode and the time when the condition is met is a seventh interval, the time of entering the second operating mode is after the time when the condition is met, and the time of entering the second operating mode is earlier than the start position of the first timing, wherein the seventh interval is greater than or equal to 0; wherein the time when the condition is met includes one or more of the following times: the time when the second condition is met, the time when the third condition is met, or the time when the first timer stops.

[0386] Example 1: When the condition is met at one or more of the following: the time when the second condition is met, the time when the second condition is met, or the time when the first timer stops, the interval between the time when the second working mode is entered and the end position of the first timing is the sixth interval, and the time when the second working mode is entered is after the first timing.

[0387] Example 2: When the condition is met at any of the following times: the time when the second condition is met, the time when the second condition is met, or the time when the first timer stops, the interval between the time when the second working mode is entered and the time when this condition is met is the seventh interval, and the time when the second working mode is entered is after the time when this condition is met.

[0388] Example 3: When the time of satisfying the condition is multiple of the following: the time of satisfying the second condition, the time of satisfying the second condition, or the time when the first timer stops, the interval between the time of entering the second working mode and the last time of satisfying these multiple conditions is the seventh interval, and the time of entering the second working mode is after the last time of satisfying these multiple conditions.

[0389] Figure 16 is a schematic diagram of the moment when the second working mode is entered.

[0390] As shown in Figure 16a), the interval between the moment of entering the second operating mode and the end position of the first timing is the sixth interval, and the moment of entering the second operating mode is after the first timing. It can be understood that when the sixth interval is equal to 0, the moment of entering the second operating mode is located at the end position of the first timing. That is, when the sixth interval is equal to 0, the interval between the moment of entering the second operating mode and the end position of the first timing is the sixth interval, which can be replaced by: the moment of entering the second operating mode is located at the end position of the first timing.

[0391] As shown in Figure 16b), the interval between the moment of entering the second working mode and the moment the condition is met is the seventh interval, and the moment of entering the second working mode is after the moment the condition is met. It can be understood that when the seventh interval is equal to 0, the moment of entering the second working mode is located at the moment the condition is determined to be met. That is, when the seventh interval is equal to 0, the interval between the moment of entering the second working mode and the moment the condition is met is the seventh interval, which can be replaced by: the moment of entering the second working mode is located at the moment the condition is determined to be met. It can be understood that the moment the terminal determines the condition is met can be slightly later than the actual moment the condition is met. In other words, after knowing that the condition is met, the terminal can immediately enter the second working mode.

[0392] Optionally, the interval between the moment of entering the second working mode and the end position of the first timing is the sixth interval, and the condition for entering the second working mode after the first timing is that the latency requirement of the terminal is less than or equal to the first threshold.

[0393] In other words, provided that the latency of the terminal is less than the first threshold, the interval between the moment of entering the second working mode and the end position of the first timing is the sixth interval, and the moment of entering the second working mode is after the first timing.

[0394] The first threshold can be preset, and this application does not limit it.

[0395] Optionally, the interval between the moment of entering the second working mode and the moment of satisfying the condition is the seventh interval, the moment of entering the second working mode is after the moment of satisfying the condition, and the condition that the moment of entering the second working mode is earlier than the starting position of the first timing is that the energy-saving demand of the terminal is greater than or equal to the second threshold.

[0396] In other words, provided that the energy saving requirement of the terminal is greater than or equal to the second threshold, the interval between the time of entering the second working mode and the time of satisfying the condition is the seventh interval, the time of entering the second working mode is after the time of satisfying the condition, and the time of entering the second working mode is earlier than the starting position of the first timing.

[0397] Optionally, the energy-saving requirement of the terminal is related to its remaining battery power. For example, there is a corresponding relationship between the terminal's remaining battery power and its energy-saving requirement. As an example and not a limitation, the energy-saving requirement of the terminal is divided into levels from 1 to 10, where 1 represents the lowest energy-saving requirement and 10 represents the highest energy-saving requirement. For example, if the terminal's remaining battery power is less than or equal to 10%, the corresponding energy-saving requirement is 10; if the terminal's remaining battery power is greater than 40% and less than or equal to 50%, the corresponding energy-saving requirement is 5; and if the terminal's remaining battery power is greater than or equal to 90%, the corresponding energy-saving requirement is 1. This application does not limit this.

[0398] The second threshold can be preset, and this application does not limit it.

[0399] Optionally, if the energy-saving requirement of the terminal is greater than or equal to the second threshold, and the condition is met after the end of the time domain resource for monitoring low-power signals and before the first timing, the network device may not send PDCCH at the first timing; accordingly, the terminal may monitor low-power signals and / or PDCCH at the time domain resource for monitoring low-power signals in the next paging cycle of the paging cycle in which the first timing is located.

[0400] In one possible implementation, for the network device, if the condition is met before the start of the time-domain resource for transmitting low-power signals, the interval between the time when the terminal enters the second operating mode and the time when the condition is met is an eighth interval, and the time when the terminal enters the second operating mode is after the time when the condition is met, wherein the eighth interval is greater than or equal to 0; wherein the time when the condition is met is one or more of the following times: the time when the second condition is met, the time when the third condition is met, or the time when the first timer stops. Correspondingly, for the terminal, if the condition is met before the start of the time-domain resource for monitoring low-power signals, the interval between the time when the terminal enters the second operating mode and the time when the condition is met is an eighth interval, and the time when the terminal enters the second operating mode is after the time when the condition is met, wherein the eighth interval is greater than or equal to 0; wherein the time when the condition is met is one or more of the following times: the time when the second condition is met, the time when the third condition is met, or the time when the first timer stops.

[0401] Figure 17 is another schematic diagram of the moment when the second working mode is entered.

[0402] As shown in Figure 17, if the condition is met before the start of the time domain resource for monitoring low-power signals, the interval between the time of entering the second working mode and the time of meeting the condition is the eighth interval, and the time of entering the second working mode is after the time of meeting the condition.

[0403] It is understandable that, when the eighth interval is equal to 0, the moment of entering the second working mode is the moment when the condition is determined to be met. That is, when the eighth interval is equal to 0, the interval between the moment of entering the second working mode and the moment the condition is met is the eighth interval, which can be replaced by: the moment of entering the second working mode is the moment when the condition is determined to be met. It is understandable that the moment the terminal determines that the condition is met can be slightly later than the actual moment the condition is met. In other words, after knowing that the condition is met, the terminal can immediately enter the second working mode.

[0404] It is also understandable that, when the eighth interval is greater than 0, the moment of entering the second working mode can be before or after the time domain resource for monitoring the low-power signal.

[0405] It is understood that this application does not limit the order in which the network device and the terminal determine that the terminal has entered the second working mode. That is, in practical application scenarios, the network device can determine that the terminal has entered the second working mode before or after the terminal determines that the terminal has entered the second working mode, or the network device can determine that the terminal has entered the second working mode and the terminal can determine that the terminal has entered the second working mode simultaneously. This application does not impose any limitations on this.

[0406] In step 1540, the terminal enters the second working mode.

[0407] It is understandable that the terminal can enter the second working mode based on the time determined by the terminal, that is, the terminal can enter the second working mode at the determined time.

[0408] In one possible implementation, if the second condition is met, and if the second condition is met after the start of the time-domain resource for monitoring the low-power signal and before the first timing, the second condition is not used as a condition for determining whether to enter the second operating mode.

[0409] In another possible implementation, the time-domain resources for monitoring the low-power signal do not overlap with the time period in which the first timer operates.

[0410] In other words, network devices can be configured such that the time domain resources for monitoring low-power signals do not overlap with the time period during which the first timer runs (i.e., the time period for monitoring PDCCH).

[0411] Based on the aforementioned method 1500, for the terminal, by comprehensively considering at least two of the following factors—time-domain resources for monitoring low-power signals, channel measurement results of the terminal, and indication information indicating entry into the second operating mode or entry into the second operating mode after the timer stops—the conditions for the terminal to enter the second operating mode are restricted. Thus, the terminal can clearly determine the time to enter the second operating mode. Furthermore, this method can also meet different energy-saving or latency requirements for terminals, which is beneficial for energy saving or ensuring service capacity.

[0412] For network devices, the conditions for a terminal to enter the second working mode are limited by comprehensively considering at least two of the following factors: time domain resources for transmitting low-power signals, channel measurement results of the terminal, indication information instructing the terminal to enter the second working mode, or the terminal entering the second working mode after the timer stops. In this way, the network device can clearly determine what signal to send at what time, which is beneficial for energy saving of the network device and ensuring service capacity.

[0413] To address the aforementioned technical issues, a third approach involves determining the time to exit the second operating mode by comprehensively considering both the time-domain resources for monitoring low-power signals and the times when uplink information transmission occurs. This allows the terminal to clearly determine when to exit the second operating mode.

[0414] Figure 18 is a schematic flowchart of a communication method 1800 (which can be referred to as communication method four for ease of description) provided in an embodiment of this application. The steps of method 1800 are described in detail below.

[0415] The method is described in method 1800 using the interaction between a first communication device and a second communication device as an example, and should not be construed as limiting the scope of this application.

[0416] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIPs containing modem cores), chip systems, or processors, etc.). This application does not limit the scope of the application.

[0417] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0418] The following description uses the first communication device as the terminal and the second communication device as a network device as an example to illustrate the communication method 2100 provided in this application.

[0419] In step 1810, the network device determines the time-domain resources for transmitting low-power signals.

[0420] Accordingly, in step 1820, the terminal determines the time-domain resources for monitoring low-power signals.

[0421] It is understandable that network devices can determine the time-domain resources for transmitting low-power signals, and correspondingly, terminals can also determine the time-domain resources for monitoring low-power signals.

[0422] For a detailed description of steps 1810 and 1820, please refer to the relevant descriptions of steps 710 and 720 above. For the sake of brevity, they will not be repeated here.

[0423] In step 1830, the network device sends a low-power signal.

[0424] Accordingly, in step 1840, the terminal monitors the low-power signal.

[0425] Understandably, network devices can transmit low-power signals on the time-domain resources designated for transmitting low-power signals. Correspondingly, terminals can monitor low-power signals on the time-domain resources designated for monitoring low-power signals.

[0426] Optionally, for the network device, the low-power signal transmitted during the time-domain resource transmission of the low-power signal is used to indicate whether there is PDCCH transmission at a second time. Correspondingly, for the terminal, the low-power signal transmitted during the time-domain resource transmission of the low-power signal is used to indicate whether there is PDCCH transmission at a second time.

[0427] As mentioned in the terminology section above, when the terminal is in RRC connected state, the low-power signal can be used to indicate whether there is subsequent PDCCH transmission or data service transmission. In this alternative approach, the low-power signal used for monitoring time-domain resource transmission of the low-power signal can be used to indicate whether there is PDCCH transmission at a first opportune moment.

[0428] In step 1850, the network device and the terminal determine the moment when the terminal exits the second operating mode.

[0429] The second operating mode is a mode for monitoring low-power signals. The time when the second operating mode is exited depends on the time domain resources available for monitoring low-power signals and the time when uplink information is being transmitted.

[0430] In other words, the terminal can determine when to exit the second working mode based on the time domain resources of the low-power signal monitoring and the time when uplink information is transmitted.

[0431] In one possible implementation E, for the network device, the condition for the terminal to exit the second operating mode is related to the time domain resources for transmitting low-power signals and the time of uplink information transmission, including: if the time of uplink information transmission is before the time domain resources for transmitting low-power signals, the interval between the time of the terminal exiting the second operating mode and the time of uplink information transmission is a ninth interval; the time of the terminal exiting the second operating mode is after the time of uplink information transmission; and the time of the terminal exiting the second operating mode is earlier than the start position of the time domain resources for transmitting low-power signals. Correspondingly, for the terminal, the condition for exiting the second operating mode is related to the time domain resources for monitoring low-power signals and the time of uplink information transmission, including: if the time of uplink information transmission is before the time domain resources for monitoring low-power signals, the interval between the time of the terminal exiting the second operating mode and the time of uplink information transmission is a ninth interval; the time of the terminal exiting the second operating mode is after the time of uplink information transmission; and the time of the terminal exiting the second operating mode is earlier than the start position of the time domain resources for monitoring low-power signals. Among them, the ninth interval is greater than or equal to 0.

[0432] Figure 19 is a schematic diagram of the moment when exiting the second working mode.

[0433] As shown in Figure 19, when the time of uplink information transmission is before the time domain resource for monitoring low-power signals, the interval between the time of exiting the second working mode and the time of uplink information transmission is the ninth interval. The time of exiting the second working mode is after the time of uplink information transmission, and the time of exiting the second working mode is earlier than the start position of the time domain resource for monitoring low-power signals.

[0434] It is understandable that when the ninth interval is equal to 0, the time of exiting the second operating mode is the time when uplink information transmission is confirmed. That is, when the ninth interval is equal to 0, the interval between the time of exiting the second operating mode and the time when uplink information transmission occurs is the ninth interval, which can be replaced by: the time of exiting the second operating mode is the time when uplink information transmission is confirmed. It is understandable that the time when the terminal confirms uplink information transmission can be slightly later than the actual time of uplink information transmission. In other words, after knowing that uplink information transmission has occurred, the terminal can immediately exit the second operating mode.

[0435] In the above implementation method F, correspondingly for the network device, the network device may not send low-power signals on the time domain resources for monitoring low-power signals.

[0436] In other words, if there is uplink information transmission before the time domain resource for monitoring low-power signals, the network device may not send low-power signals on the time domain resource for monitoring low-power signals.

[0437] In one possible implementation F, for the network device, the condition for the terminal to exit the second operating mode is related to the time domain resources for transmitting low-power signals and the time of uplink information transmission, including: if the time of uplink information transmission is after the time domain resources for transmitting low-power signals and before the second timing, the interval between the time of the terminal exiting the second operating mode and the start position of the second timing is a tenth interval; the time of the terminal exiting the second operating mode is before the second timing; and the time of the terminal exiting the second operating mode is after the time domain resources for transmitting low-power signals. Correspondingly, for the terminal, the condition for exiting the second operating mode is related to the time domain resources for monitoring low-power signals and the time of uplink information transmission, including: if the time of uplink information transmission is after the time domain resources for monitoring low-power signals and before the second timing, the interval between the time of the terminal exiting the second operating mode and the start position of the second timing is a tenth interval; the time of the terminal exiting the second operating mode is before the second timing; and the time of the terminal exiting the second operating mode is after the time domain resources for monitoring low-power signals. Wherein, the tenth interval is greater than or equal to 0.

[0438] Figure 20 is another schematic diagram of the moment of exiting the second working mode.

[0439] As shown in Figure 20, when there is uplink information transmission after the time domain resources for monitoring low-power signals and before the second timing, the interval between the time of exiting the second working mode and the start position of the second timing is the tenth interval, the time of exiting the second working mode is before the second timing, and the time of exiting the second working mode is after the time domain resources for monitoring low-power signals.

[0440] It is understandable that when the tenth interval is equal to 0, the interval between the time of exiting the second working mode and the starting position of the second timing is the tenth interval, which can be replaced by: the time of exiting the second working mode is located at the starting position of the second timing.

[0441] It is also understandable that the terminal may determine that uplink information is being transmitted slightly later than the actual time of uplink information transmission. If this tenth interval is greater than 0, the terminal can immediately exit the second operating mode after knowing that uplink information is being transmitted.

[0442] Optionally, the method 1800 further includes: the network device sending the PDCCH at the second opportune moment. Accordingly, the terminal monitors the PDCCH at the second opportune moment.

[0443] In other words, the network device may send the PDCCH at this second opportune moment. Correspondingly, the terminal can monitor the PDCCH at this second opportune moment.

[0444] Based on the above method 1800, for the terminal, by comprehensively considering the time domain resources for monitoring low-power signals and the time when there is uplink information transmission, the conditions for the terminal to exit the second working mode are restricted, so that the terminal can clearly determine the time to exit the second working mode.

[0445] For network devices, by comprehensively considering the time domain resources for sending low-power signals and the time when uplink information is transmitted, the conditions for the terminal to exit the second working mode are limited. Thus, network devices can clearly determine what signals to send at what time, which is beneficial for energy saving of network devices and ensuring service capacity.

[0446] It is understood that method 1800 can be deployed or used in combination with one or more of the above-mentioned methods 700, 1400 or 1500.

[0447] To address the aforementioned technical issues, the fourth aspect involves clarifying the behavior of network devices and terminals. From the perspective of network devices, network capacity is guaranteed by limiting the signal reception latency of terminals.

[0448] Figure 21 is a schematic flowchart of a communication method 2100 (which can be referred to as communication method five for ease of description) provided in an embodiment of this application. The steps of method 2100 are described in detail below.

[0449] The method is described in method 2100 using the interaction between the first communication device and the second communication device as an example, and should not be construed as limiting the scope of this application.

[0450] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores), chip systems, or processors, etc.), and this application does not limit it in this regard.

[0451] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0452] The following description uses a first communication device as the first terminal and a second communication device as a network device as an example to illustrate the communication method 2100 provided in this application.

[0453] In step 2110, the network device determines M opportunities for the first terminal.

[0454] Here, the M timings belong to M adjacent non-continuous reception periods, where M is an integer greater than or equal to 2.

[0455] In other words, the network device can first determine M opportunities for the first terminal.

[0456] In step 2120, the network device sends indication information to the first terminal, the indication information being used to indicate the M timings. Accordingly, the first terminal receives the indication information from the network device.

[0457] For example, after determining M opportunities for the first terminal, the network device can send indication information to the first terminal to indicate the M opportunities. Accordingly, the first terminal receives the indication information from the network device.

[0458] In step 2130, the network device transmits M DCIs at the M time points. Correspondingly, the first terminal receives DCIs at one or more of the M time points.

[0459] The M DCIs are used to schedule M PDSCHs, and the information transmitted by the M PDSCHs is identical. In other words, each DCI is used to schedule one PDSCH.

[0460] It is understandable that although the network device can send M DCIs at the M times, the first terminal can receive DCIs at at least one of the M times.

[0461] Alternatively, the DCI may be P-RNTI scrambled, or the DCI may be C-RNTI scrambled.

[0462] Specifically, when the first terminal is in the RRC idle / inactive state, the DCI can be scrambled with P-RNTI; when the first terminal is in the RRC connected state, the DCI can be scrambled with C-RNTI.

[0463] It is understandable that scrambling can be interpreted as a functional limitation.

[0464] Based on the above method 2100, the behavior of network devices and terminals is clearly defined. By limiting the signal reception latency of terminals, network capacity can be guaranteed. In addition, terminals with different energy-saving or latency requirements can be accommodated, which is beneficial for terminal energy saving or ensuring service capacity.

[0465] In response to the aforementioned technical problems, the fifth aspect involves comprehensively considering the location relationship between the monitored or received first signal and the resource determined by the resource configuration information, to determine whether the terminal should continue monitoring or receiving the first signal, stop monitoring or receiving the first signal, or monitor other signals at the resource determined by the resource configuration information or for a period of time before the resource determined by the resource configuration information.

[0466] Figure 22 is a schematic flowchart of a communication method 2200 (which can be referred to as communication method six for ease of description) provided in an embodiment of this application. The steps of method 2200 are described in detail below.

[0467] The method is described in method 2200 using the interaction between the first communication device and the second communication device as an example, and should not be construed as limiting the scope of this application.

[0468] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIPs containing modem cores), chip systems, or processors, etc.). This application does not limit the scope of the application.

[0469] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0470] The following description uses the first communication device as the terminal and the second communication device as a network device as an example to illustrate the communication method 2200 provided in this application.

[0471] In step 2210, the terminal monitors or receives the first signal.

[0472] The first signal is used to determine the monitoring PDCCH.

[0473] In one possible implementation, the first signal is used to trigger the terminal to start monitoring the PDCCH after a period of time.

[0474] In other words, after receiving the first signal, the terminal can start monitoring the PDCCH some time after receiving the first signal.

[0475] In step 2220, the network device sends resource configuration information to the terminal. Accordingly, the terminal receives the resource configuration information from the network device.

[0476] The following explains the resource configuration information.

[0477] In one possible implementation, the resource configuration information includes one or more of the following: configuration information related to SPS; or configuration information related to CG; or other resource configuration information that is periodically received and / or periodically sent.

[0478] The configuration information for CG can include: configuration information for CG type 1 and configuration information for CG type 2.

[0479] In step 2230, the terminal performs the first target action.

[0480] The first target action includes: within the time range from a first time before the start time of the first resource to the start time of the first resource, not monitoring or stopping the reception of the first signal, and / or, from the start time of the first resource, performing one or more of the following: not monitoring or not receiving the first signal; or, monitoring or receiving the PDCCH; or, monitoring or receiving the PDSCH; or, receiving the reference signal; or, sending a scheduling request; or, sending a physical random access channel; or, sending a reference signal; or, sending the PUCCH; or, sending the PUSCH.

[0481] It is understood that when the terminal performs the first target action, the network device correspondingly performs a second target action, which includes: not sending the first signal within the time range from a first time before the start time of the first resource to the start time of the first resource; and / or, from the start time of the first resource, performing one or more of the following: not sending the first signal; or sending PDCCH; or sending PDSCH; or sending a reference signal; or receiving a scheduling request; or receiving a physical random access channel; or receiving a reference signal; or receiving PUCCH; or receiving PUSCH.

[0482] It is also understandable that the first target action performed by the terminal corresponds to the second target action performed by the network device. For example, if the terminal monitors or receives a PDCCH, the network device sends a PDCCH; if the terminal monitors or receives a PDSCH, the network device sends a PDSCH. For the sake of simplicity, examples will not be provided here.

[0483] In one possible implementation, the first time may be related to one or more of the following: the wake-up latency required for the terminal to wake from sleep, the synchronization time required for the terminal to meet synchronization performance requirements, or the processing time of the synchronization signal.

[0484] For example, after receiving the resource configuration information, the terminal can determine the start time of the first resource based on the resource configuration information. In other words, the resource configuration information is used to determine the start time of the first resource.

[0485] The following is an explanation of the first resource.

[0486] In one possible implementation, the first resource includes one or more of the following: resources configured with SPS-related configuration information; or resources configured with CG-related configuration information; or resources configured with other resource configuration information that periodically receives and / or periodically sends information.

[0487] The first resource determined by the resource allocation information includes time-domain resources and / or frequency-domain resources.

[0488] Figure 23 is a schematic diagram of the positional relationship between monitoring or receiving a first signal, a first time, and a first resource provided in an embodiment of this application.

[0489] As shown in Figure 23, the terminal monitors or receives the first signal for a period of time before time T1, and time T2, which is the first time after time T1, is the start time (or start time) of the first resource. The interval between T1 and T2 is the first time.

[0490] It is understandable that the first time before the start time of the first resource mentioned in step 2230 above, from the first time to the start time of the first resource, where the first time is a time period and the start time of the first resource is the end time of the first time, can be understood as the time range from the start time of the first time before the start time of the first resource to the start time of the first resource. The time range from the first time before the start time of the first resource to the start time of the first resource is also known as the first time.

[0491] For example, the first resource is a time-domain resource, and the terminal continuously monitors or receives PDCCH, or monitors or receives PDSCH, or receives reference signals, or sends scheduling requests, or sends physical random access channels, or sends reference signals, or sends PUCCH, or sends PUSCH within the first resource.

[0492] In one possible implementation, the method 2200 further includes: the terminal receiving the first signal starting from a second time from the starting position of the first resource.

[0493] For example, the terminal can begin monitoring or receiving the first signal after the first resource ends, that is, the length of the second time is the same as the length of the first resource.

[0494] Optionally, the second time may be determined by one or more of the following: the first resource, drx-HARQ-RTT-TimerDL, and drx-Retransmission-TimerDL.

[0495] The length of the second time is not limited and is only related to the first resource, drx-HARQ-RTT-TimerDL, drx-Retransmission-TimerDL, etc. For example, the second time may include the activation time of discontinuous DRX reception. For example, the second time may include the activation time that is not part of the DRX, but the time when the terminal is monitoring or receiving PDCCH; or, the second time may include the time when monitoring or receiving PDSCH; or, the second time may include the time when receiving reference signals; or, the second time may include the time when sending scheduling requests; or, the second time may include the time when sending physical random access channels; or, the second time may include the time when sending reference signals; or, the second time may include the time when sending PUCCH; or, the second time may include the time when sending PUSCH; or, the second time may include the time when the terminal's high-power receiver wake-up; or, the second time may include the time when the terminal operates at maximum module capacity.

[0496] In one possible implementation, the first time is determined based on first indication information received from the network device; or, the length of the first time is predefined.

[0497] Understandably, when the first time is determined based on the first indication information, the terminal can receive the first indication information from the network device to indicate the length of the first time. Accordingly, the network device can send the first indication information to the terminal.

[0498] In one possible implementation, the method 2200 further includes: the terminal sending second indication information to determine a third time, which is a first time supported by the terminal. Accordingly, the network device receives the second indication information.

[0499] As an example, the UE capability can be an example of the second indication information, that is, the terminal can send the UE capability to the network, which is used to indicate the length of a first time supported by the terminal. For example, the UE capability contains the length of the first time supported by the terminal.

[0500] In one possible implementation, the method 2200 further includes: the terminal sending third indication information for determining a fourth time, which is the first time desired by the terminal.

[0501] As an example, the UE assistance information can be an example of the third indication information, that is, the terminal can send UE assistance information to the network to indicate the length of the first time that the terminal expects the network device to configure. For example, the UE assistance information includes the length of the first time that the terminal expects the network device to configure.

[0502] Optionally, the length of the fourth time period is greater than or equal to the length of the third time period.

[0503] As an example and not a limitation, the length of the first time that the terminal expects the network device configuration contained in the UE auxiliary information is greater than or equal to the length of the first time that the terminal supports contained in the UE capabilities.

[0504] For example, the length of the first time that the terminal expects the network device configuration contained in the UE auxiliary information is 20ms, and the length of the first time that the terminal supports contained in the UE capabilities is 15ms.

[0505] For example, the UE capability includes a first time duration supported by the terminal of 15ms, and the network device configures the first time duration for the terminal to be 15ms. If the UE assistance information includes a first time duration that the terminal expects the network device to configure to be 20ms, the base network device can update the parameters; for example, the network device can update the first time duration to 20ms.

[0506] Optionally, the terminal can enter deep sleep before the first time.

[0507] Optionally, the modulation method of the first signal includes one or more of the following: on-off keying modulation, sequence modulation, phase modulation, ZC sequence carrying, or frequency shift keying modulation.

[0508] Based on the above method 2200, when resource configuration information is obtained, the terminal can no longer receive the first signal, but instead use the resource transmission information determined by the resource configuration information to reduce the transmission delay of the information.

[0509] In response to the aforementioned technical problems, the sixth aspect involves comprehensively considering the location relationship between the monitored or received first signal and the resource determined by the resource configuration information, to determine whether the terminal should continue monitoring or receiving the first signal, stop monitoring or receiving the first signal, or monitor other signals at the resource determined by the resource configuration information or for a period of time before the resource determined by the resource configuration information.

[0510] Figure 24 is a schematic flowchart of a communication method 2400 (which can be referred to as communication method seven for ease of description) provided in an embodiment of this application. The steps of method 2400 are described in detail below.

[0511] The method is described in method 2400 using the interaction between the first communication device and the second communication device as an example, and should not be construed as limiting this application in any way.

[0512] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIPs containing modem cores), chip systems, or processors, etc.). This application does not limit the scope of the application.

[0513] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0514] The following description uses the first communication device as the terminal and the second communication device as a network device as an example to illustrate the communication method 2200 provided in this application.

[0515] In step 2410, the network device enables or activates monitoring or transmitting the first signal. Correspondingly, the terminal is enabled or activated to monitor or receive the first signal.

[0516] The first signal is used to determine the monitoring PDCCH.

[0517] In one possible implementation, the first signal is used to trigger the terminal to start monitoring the PDCCH after a period of time.

[0518] In other words, after receiving the first signal, the terminal can start monitoring the PDCCH some time after receiving the first signal.

[0519] Optionally, the modulation method of the first signal includes one or more of the following: on-off keying modulation, sequence modulation, phase modulation, ZC sequence carrying, or frequency shift keying modulation.

[0520] For a detailed description of the first signal, please refer to the relevant description in Method 2200 above. For the sake of brevity, it will not be repeated here.

[0521] In step 2420, the network device sends resource configuration information to the terminal. Correspondingly, the terminal receives the resource configuration information from the network device.

[0522] It is understandable that network devices send resource configuration information to terminals, and terminals receive this resource configuration information from the network devices; that is, the terminal is configured with resource configuration information by the network devices.

[0523] In one possible implementation, the resource configuration information includes one or more of the following: configuration information related to SPS; or configuration information related to CG; or other resource configuration information that is periodically received and / or periodically sent.

[0524] For a detailed description of the resource configuration information, please refer to the relevant description in Method 2200 above. For the sake of brevity, it will not be repeated here.

[0525] In step 2430, the terminal determines the first resource based on the resource configuration information.

[0526] In one possible implementation, the first resource includes one or more of the following: resources configured with SPS-related configuration information; or resources configured with CG-related configuration information; or resources configured with other resource configuration information that periodically receives and / or periodically sends information.

[0527] For a detailed description of the first resource, please refer to the relevant description in Method 2200 above. For the sake of brevity, it will not be repeated here.

[0528] In step 2440, the terminal performs a first target action on the first resource. Correspondingly, the network device performs a second target action on the first resource.

[0529] For a detailed description of the first target action and the second target action, please refer to the relevant description in Method 2200 above. For the sake of brevity, it will not be repeated here.

[0530] In one possible implementation, when monitoring or receiving the first signal is enabled and the terminal is configured with resource configuration information, the terminal can ignore the original function or process of the first resource determined based on the resource configuration information, or the terminal can stop or suspend the relevant timer of the first resource determined based on the resource configuration information.

[0531] For example, within a first resource, the priority of monitoring or receiving a first signal can be higher than the priority of the first resource determined based on resource configuration information. The following are several examples of making the priority of monitoring or receiving a first signal higher than the priority of the first resource determined based on resource configuration information.

[0532] Example 1: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of monitoring or receiving the PDCCH.

[0533] Example 2: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of monitoring or receiving the PDSCH.

[0534] Example 3: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of receiving the reference signal.

[0535] Example 4: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of sending a scheduling request.

[0536] Example 5: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of transmitting the physical random access channel.

[0537] Example 6: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of transmitting the reference signal.

[0538] Example 7: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of sending the PUCCH.

[0539] Example 8: Within the first resource, the priority of monitoring or receiving the first signal is higher than the priority of sending PUSCH.

[0540] Based on the above method 2400, when the terminal obtains the resource configuration information, it no longer receives, monitors, or sends the above signals or channels on the resources determined based on the resource configuration information, thereby reducing the terminal's power consumption.

[0541] To address the aforementioned technical issues, in the seventh aspect, by enabling or activating only the monitoring or receiving of the first signal, or by configuring or activating only the resource configuration information, the problems caused by simultaneously activating both the monitoring or receiving of the first signal and the resource configuration information are avoided.

[0542] Figure 25 is a schematic flowchart of a communication method 2500 (which can be referred to as communication method eight for ease of description) provided in an embodiment of this application. The steps of method 2500 are described in detail below.

[0543] The method is described in method 2500 using the interaction between the first communication device and the second communication device as an example, and should not be construed as limiting the scope of this application.

[0544] The first communication device may be a terminal, a communication module in the terminal, or a component in the terminal responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIPs containing modem cores), chip systems, or processors, etc.). This application does not limit the scope of the application.

[0545] The second communication device can be a network device, a communication module in a network device, or a component in a network device responsible for communication functions (such as circuits, chips (such as modem chips, also known as baseband chips, or SoC chips or SIP chips containing modem cores, chip systems or processors, etc.), which are not limited in this application.

[0546] The communication method 2500 provided in this application will be described below using a first communication device as the terminal and a second communication device as a network device as an example. The communication method 2500 may include steps 2510 and / or 2520. The various steps in method 2500 will be described in detail below.

[0547] In step 2510, the network device enables or activates monitoring or sending the first signal, but disables or disables resource configuration information. Correspondingly, the terminal is enabled or activated to monitor or receive the first signal, but does not expect to be configured with resource configuration information.

[0548] The first signal is used to determine the monitoring PDCCH.

[0549] In one possible implementation, the first signal is used to trigger the terminal to start monitoring the PDCCH after a period of time.

[0550] In other words, after receiving the first signal, the terminal can start monitoring the PDCCH some time after receiving the first signal.

[0551] Optionally, the modulation method of the first signal includes one or more of the following: on-off keying modulation, sequence modulation, phase modulation, ZC sequence carrying, or frequency shift keying modulation.

[0552] For a detailed description of the first signal, please refer to the relevant description in Method 2200 above. For the sake of brevity, it will not be repeated here.

[0553] In one possible implementation, the resource configuration information includes one or more of the following: configuration information related to SPS; or configuration information related to CG; or other resource configuration information that is periodically received and / or periodically sent.

[0554] For a detailed description of the resource configuration information, please refer to the relevant description in Method 2200 above. For the sake of brevity, it will not be repeated here.

[0555] In step 2520, the network device enables or configures resource configuration information, and disables or disables the monitoring or transmission of the first signal. Accordingly, the terminal is enabled or configured with resource configuration information, and does not expect to be enabled or activated to monitor or receive the first signal.

[0556] It is understandable that, for a terminal, monitoring or receiving the first signal and resource configuration information will not be configured or enabled simultaneously. For example, only monitoring or receiving the first signal may be configured or enabled, without configuring resource configuration information. Alternatively, only resource configuration information may be configured, without configuring or enabling monitoring or receiving the first signal.

[0557] For example, network devices may only allow terminals to monitor or receive low-power wake-up signals, but the network may not enable or activate SPS or CG resources. In other words, the transmission of low-power wake-up signals and the configuration of SPS / CG resources may not take effect simultaneously or coexist.

[0558] Based on the above method 2500, at any given time, the terminal only enables or activates monitoring or receiving the first signal, or is only configured with resource configuration information, avoiding the mutual exclusion problem of two actions occurring simultaneously and reducing the complexity of the base station and the terminal. Furthermore, based on the above step 2510, the terminal can remain in the state of monitoring or receiving the first signal for an extended period. Since the power consumption of the terminal monitoring or receiving the first signal is low, energy saving can be achieved. Based on the above step 2520, the terminal can perform information transmission on resources determined by the configured resource configuration information, reducing information transmission latency.
