Description

Monitoring timing indication method, monitoring method, communication nodes and storage media Technical Field

[0001] This application relates to the field of wireless communication technology, such as a method for indicating the timing of listening, a listening method, a communication node, and a storage medium. Background Technology

[0002] Discontinuous Reception (DRX) in wireless communication allows User Equipment (UE) to periodically enter a sleep state, thereby saving UE power consumption. The basic mechanism of DRX is that the base station provides DRX configuration to the UE in connected mode. In the DRX configuration, each DRX cycle consists of an on period and an off period. During the on period, the UE wakes up and listens to the Physical Downlink Control Channel (PDCCH). During the off period, the UE determines whether to continue listening to the PDCCH based on other timers (e.g., the DRX-Inactivity Timer), thereby reducing UE power consumption.

[0003] According to the DRX mechanism, even without data authorization, the UE needs to wake up during the start period of each DRX cycle, resulting in unnecessary power waste. In some scenarios, the base station can send a wake-up signal to notify the UE whether to wake up in the next DRX cycle, which can avoid the power waste caused by the UE waking up when there is no data authorization to some extent.

[0004] However, whether the UE wakes up according to the DRX configuration period or according to the wake-up signal, the UE must wake up at the beginning of the DRX period, and the wake-up time must last for at least the entire on period. But in reality, there may be no data authorization during some periods of the DRX period. Therefore, how to further reduce power waste and achieve more efficient terminal energy saving is an urgent problem to be solved. Summary of the Invention

[0030] The present application will now be described in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0031] With the development of wireless communication technology and the increasing demand for communication from users, in order to meet the communication requirements of low latency, high reliability and high speed, the evolution and enhancement of fifth generation mobile communication technology (5G) (5G-Advanced, 5G-A) and sixth generation mobile communication technology (6G) have become the trend of future network development and implementation.

[0032] The Industrial Internet of Things (IIoT) can effectively connect an increasing number of factory devices and sensors in various industrial settings, transmitting video, images, sensor messages, and control commands according to different industrial scenarios and operational requirements, thereby promoting the digitalization, automation, and intelligentization of industries. However, for the "last hop" of IIoT—field-level device communication—a high-performance, high-reliability short-range wireless communication technology is still needed as an extension of cellular mobile networks to communicate in conjunction with them, meeting the needs of factory production networks and accelerating the development of the Industrial Internet.

[0033] In short-range wireless communication technologies in industrial scenarios, base stations or head nodes can provide user equipment (UE) with functions such as resource configuration, resource scheduling, and access management. Figure 1 shows a schematic diagram of a network topology in an industrial scenario. As shown in Figure 1, the communication network includes not only links from the base station to the UE, but also direct links from UE to UE, also known as side links (SL). When there is a service transmission requirement between user equipment (UE), the service data between UEs does not pass through the network side, that is, it does not go through the cellular link between the UE and the base station for forwarding, but is directly transmitted from the data source UE to the target UE through the SL. In industrial scenarios, under the coverage of the base station, there are both directly connected UEs and some remote UEs, which are directly connected to the head node. The small network formed by the remote UEs (or member UEs) and the head node can be called a micronet. In the micronet, only the head node needs to be connected to the base station, and the member UEs only need to establish a connection with the head node to realize communication between UEs or between a UE and the base station. This technology can alleviate the burden on cellular networks, reduce battery power consumption of user devices, effectively meet the requirements of high data rate services and proximity services, and also support direct communication between UEs in scenarios without network coverage. It can also meet the low latency and high reliability communication requirements of industrial networks. Similarly, in short-range wireless communication technologies for industrial scenarios, research is needed on terminal energy-saving technologies to reduce terminal power consumption, extend terminal battery life, and improve the sustainable usability of terminals.

[0034] In this embodiment, the first communication node mainly refers to the transmitter of the control channel, and can be one of the following: a base station, a head node, or a UE. The head node is a node with resource management functions, can have the functions of a UE, can establish a connection with the base station, and can manage and control its subordinate UEs. For example, the head node can be a relay node, an access point (AP), or a UE-type node. The second communication node is the receiver of the control channel, and can be either a head node or a UE.

[0035] In one example, the first communication node is a base station, and the second communication node is a terminal. In another example, the first communication node is a head node, and the second communication node is a terminal. In yet another example, both the first and second communication nodes are terminals. In still another example, the first communication node is a base station, and the second communication node is a head node.

[0036] Figure 2 is a flowchart of a monitoring timing indication method according to an embodiment. This method can be applied to a first communication node, which can be a transmitter of a control channel or a transmitter of monitoring timing indication information. As shown in Figure 2, the method provided in this embodiment includes steps 110 and 120.

[0037] In step 110, a listening timing indication information is sent, which indicates at least one listening opportunity for the control channel within at least one discontinuous reception DRX period.

[0038] In step 120, a control channel is transmitted during the at least one listening opportunity.

[0039] In this embodiment, the first communication node can send a listening timing indication message to the second communication node to indicate the listening timing within at least one discontinuous DRX reception period. For example, it can indicate the listening timing within the current DRX period (of which the listening timing indication message is transmitted) and / or the listening timing within the next DRX period. The listening timing can be used to indicate when the second communication node is woken up, or it can be used to indicate when the second communication node listens to the control channel. During other periods outside the listening timing, the second communication node can be in a dormant state or not listen to the control channel. Whether the second communication node is dormant during other periods outside the listening timing depends on whether the other periods outside the listening timing are in an active period (e.g., Active Time). If the other periods outside the listening timing are not in an active period, the second communication node can be dormant; otherwise, the second communication node cannot be dormant.

[0040] The DRX activation period depends on the status of DRX configuration-related timers (e.g., DRX persistence timer, inactivity timer, discontinuous receive retransmission timer, random access contention resolution timer, 2-step random access response window, etc.), the listening timing within the DRX cycle, and whether the second communication node is in a waiting-for-scheduling-authorization state. For example, the activation period can be determined as follows: the activation period (e.g., Active Time) includes the following times: the listening timing when the DRX persistence timer is running, or when the inactivity timer is running, or when the discontinuous receive retransmission timer is running, or when the random access contention resolution timer is running, or when the 2-step random access response window is running, or when the second communication node has sent a scheduling request and is in a waiting state, or when the second communication node waits for scheduling of a new control channel after successfully receiving a random access response. Typically, the second communication node listens to the control channel during the activation period, and can hibernate outside of the activation period.

[0041] As an example, the first communication node can instruct the second communication node to wake up and listen to the control channel during the data-granted period of the DRX cycle by listening to timing indication information, while remaining in a dormant state during the data-granted period of the DRX cycle.

[0042] As an example, the listening timing can occur anywhere within the DRX period, either during an open or closed period. For instance, the listening timing occurs during an open period within the DRX period, meaning the duration of the listening timing is shorter than the duration of the open period. For instance, the listening timing can also span both open and closed periods within the DRX period, meaning the duration of the listening timing is shorter than the DRX period itself. The starting position of the listening timing can be the beginning of the DRX period, the beginning of an open period, or any other point in time within the DRX period; the ending position of the listening timing can be the end of the DRX period, the end of an open period, or any other point in time within the DRX period.

[0043] By sending listening timing indication information, the indication and configuration of listening timing become more flexible. For DRX cycles that require monitoring the control channel, the second communication node does not need to wake up at the beginning of the DRX cycle, and the wake-up time does not necessarily have to last for the entire on-time period. Instead, it can be flexibly indicated and adjusted according to actual needs. Based on this, the second communication node can be avoided from being woken up at unnecessary times, avoiding unnecessary listening, thereby reducing power waste and achieving more efficient terminal energy saving.

[0044] In one embodiment, the at least one DRX cycle includes at least one of the following:

[0049] The current DRX cycle refers to the DRX cycle in which the monitoring timing indication information is transmitted. The next DRX cycle refers to the first DRX cycle after the current DRX cycle, that is, the DRX cycle following the current DRX cycle.

[0076] If the monitoring timing indicated by the monitoring timing indication information exceeds the range of the DRX cycle (or the opening period of the DRX cycle), the monitoring timing exceeding the DRX cycle (or the opening period of the DRX cycle) shall be applied from the beginning position of the DRX cycle (or the opening period of the DRX cycle).

[0077] In one embodiment, the monitoring timing indication information is transmitted using a specific control information format; the method further includes:

[0078] The following information is indicated by higher-level signaling for the specific control channel format: a temporary radio network identifier, a search space set, a payload size, a listening timing indication information position within the payload of the specific control channel format, and the time for the second communication node to listen to the listening timing indication information according to the search space set.

[0079] In one embodiment, the monitoring timing indication information applies to at least one bandwidth part (BWP); the indication method of the BWP includes at least one of the following:

[0097] Figure 3 is a flowchart of a monitoring method provided in one embodiment. This method can be applied to a second communication node, which can be a receiver of a control channel or a receiver of monitoring timing indication information. As shown in Figure 3, the method provided in this embodiment includes steps 210 and 220.

[0098] In step 210, a listening timing indication information is detected, which indicates at least one listening timing for the control channel within at least one DRX period.

[0099] In step 220, the control channel is monitored according to the monitoring timing indication information.

[0100] In this embodiment, the second communication node can wake up and listen to the control channel during a listening opportunity within at least one DRX cycle, based on the listening opportunity indication information. Outside of these listening opportunities, the second communication node can be in a dormant state or not listen to the control channel. Whether the second communication node is dormant outside of these listening opportunities depends on whether these other times are within an active period (e.g., Active Time). If these other times are not within an active period, the second communication node can be dormant; otherwise, it cannot. The method for determining the active period is the same as in the previous embodiment and will not be repeated here.

[0101] Based on this, the second communication node can listen to the control channel at appropriate times, making the listening more flexible and avoiding unnecessary wake-up of the second communication node at unnecessary times, thus reducing power waste and achieving more efficient terminal energy saving.

[0102] In one embodiment, the method further includes:

[0103] The receiving listening timing indication information includes at least one of the following: start effective time and effective duration.

[0104] In one embodiment, monitoring the control channel according to the monitoring timing indication information includes:

[0105] For a single DRX cycle, with the DRX persistence timer enabled, the control channel is monitored during the monitoring period within the DRX cycle.

[0106] In one embodiment, monitoring the control channel according to the monitoring timing indication information includes:

[0107] For a single DRX cycle, when the DRX persistence timer is off, the control channel is not monitored during the DRX cycle's on period or during the DRX cycle's monitoring time; that is, when the DRX persistence timer is off, the control channel does not need to be monitored during the DRX cycle.

[0108] In one embodiment, monitoring the control channel according to the monitoring timing indication information includes:

[0109] For a single DRX cycle, the control channel is monitored during the DRX activation period. The method for determining the activation period is the same as in the foregoing embodiments and will not be repeated here.

[0110] In one embodiment, monitoring the control channel according to the monitoring timing indication information includes:

[0111] For a single DRX cycle, the control channel is monitored for the entire on period of the DRX cycle if the DRX persistence timer is on and at least one of the following conditions is met:

[0112] No listening timing indication information was detected;

[0113] No notification information regarding the timing of the eavesdropping was requested.

[0114] The resources for the control channel used to transmit monitoring timing indication information were not configured.

[0115] There is no indication of when to detect listening time.

[0116] In one embodiment, monitoring the control channel according to the monitoring timing indication information includes:

[0117] For a single DRX cycle, the control channel is not monitored during the DRX cycle if the DRX persistence timer is enabled and at least one of the following conditions is met:

[0119] There is no indication of when to detect listening time.

[0120] In one embodiment, the method further includes:

[0121] Receive listening timing timer configuration information.

[0122] In one embodiment, monitoring the control channel according to the monitoring timing indication information includes:

[0123] The control channel is monitored based on the on / off state of the monitoring timing timer and the DRX persistence timer;

[0124] The monitoring of the control channel based on the on / off state of the monitoring timing timer and the DRX persistence timer includes at least one of the following: for a single DRX cycle,

[0125] During the listening timing timer, when the DRX duration timer is on, the control channel is listened to during the listening timing of the DRX cycle; when the DRX duration timer is off, the control channel is not listened to during the on period of the DRX cycle or during the listening timing of the DRX cycle.

[0126] Outside of the listening timing timer, the listening timing indicated by the listening timing indication information is invalid; that is, the second communication node can ignore the listening timing and fall back to the DRX mechanism. For example, after falling back to the DRX mechanism, the method for determining the activation period in related technologies can be adopted. Unlike before the fallback, the listening timing indicated by the listening timing indication information is not considered when determining the activation period after falling back to the DRX mechanism. For example, the method for determining the activation period after falling back to the DRX mechanism is as follows: the activation period (e.g., Active Time) includes the following times: the DRX continuous timer is running, or the inactive timer is running, or the discontinuous receive retransmission timer is running, or the random access contention resolution timer is running, or the 2-step random access response window is running, or the second communication node has sent a scheduling request and is in a waiting state, or the time during which the second communication node waits to schedule a newly transmitted control channel after successfully receiving a random access response. The second communication node listens to the control channel during the activation period; outside the activation period, the second communication node can hibernate.

[0127] In one embodiment, the method further includes:

[0128] Within the listening timing timer, the listening timing indication information indicates a valid listening timing; for example, the second communication node can use a combination of listening timing and DRX mechanisms to determine the timing for listening to the control channel. "Within the listening timing timer" can also be understood as the listening timing timer being in operation.

[0129] Outside of the listening timing timer, the listening timing indication information is invalid. For example, the second communication node can ignore the listening timing and fall back to the DRX mechanism. "Outside of the listening timing timer" can also be understood as the listening timing timer not running.

[0130] In one embodiment, the method further includes: enabling or restarting the listening timing timer under at least one of the following conditions:

[0131] Upon receiving the monitoring timing indication information, the monitoring timing timer is started or restarted after a first time interval.

[0132] The listening timing timer is periodically activated;

[0133] The listening timing timer is activated after a second time interval following the expiration of the listening timing timer.

[0134] The following examples illustrate the monitoring timing indication method of this application.

[0135] In one embodiment, the listening timing indication information can be used to indicate the listening timing of the control channel during the open period of the next DRX cycle.

[0136] In this embodiment, the first communication node sends a listening opportunity indication message, which indicates one or more listening opportunities for the control channel during the start period of the next DRX cycle. The first communication node transmits the control channel during one or more listening opportunities. The second communication node receives the listening opportunity indication message and listens for the control channel according to one or more listening opportunities indicated by the message. Each listening opportunity can be a continuous resource in the time domain. For example, each listening opportunity is N consecutive time units. For example, the time unit can be a continuous symbol, a time slot, or a millisecond, etc.

[0137] As an example, during the open period of a DRX cycle, the listening opportunity indication information indicates one or more listening opportunities for the control channel. The number of listening opportunities within a DRX cycle is pre-configured, predefined, or configured via higher-layer signaling.

[0138] In this example, the first communication node sends a listening opportunity indication message to the second communication node. The listening opportunity indication message indicates one or more listening opportunities for the control channel during the on-duration period of the next DRX cycle.

[0139] Figure 4 is a schematic diagram illustrating an embodiment of a listening opportunity during the on-duration period of the next DRX cycle. As shown in Figure 4, the listening opportunity indication information indicates one listening opportunity for the control channel within the on-duration time of a DRX cycle. It is understood that for a DRX cycle, the listening opportunity indication information may also indicate multiple listening opportunities. The number of listening opportunities within a DRX cycle can be pre-configured or predefined, or configured by the first communication node to the second communication node via higher-layer signaling.

[0140] As an example, during the open period of a DRX cycle, the listening opportunity indication information indicates one or more listening opportunities for the control channel, and the number of listening opportunities within a DRX cycle is dynamically indicated.

[0141] In this example, the first communication node sends a listening timing indication message to the second communication node. The listening timing indication message indicates one or more listening opportunities for the control channel during the On Duration time of the next DRX cycle.

[0142] Figure 5 is a schematic diagram illustrating an embodiment of indicating listening opportunities within different DRX cycles. As shown in Figure 5, for the first DRX cycle, the listening opportunity indication information indicates two listening opportunities, and for the second DRX cycle, the listening opportunity indication information indicates one listening opportunity. The number of listening opportunities within a DRX cycle can be dynamically indicated by the first communication node to the second communication node.

[0143] For example, the number of listening opportunities can be explicitly or implicitly indicated by the listening opportunity indication information. For instance, the number of listening opportunities can be explicitly indicated by the listening opportunity indication information, or the listening opportunity can be indicated by the listening opportunity indication information through a bitmap. For example, a time-domain resource with a continuous indication of 1 corresponds to one listening opportunity (i.e., implicit indication). The number of listening opportunities can also be indicated jointly by higher-layer signaling and listening opportunity indication information. For example, the first communication node indicates a list of listening opportunity numbers to the second communication node through higher-layer signaling, where each listening opportunity number in the list has an index, and the listening opportunity indication information indicates the index of the listening opportunity number.

[0144] In one embodiment, the listening timing indication information is used to indicate the listening timing of the control channel during the open period of one or more DRX cycles starting from the next DRX cycle.

[0145] In this embodiment, the first communication node sends a listening timing indication message, wherein the listening timing indication message indicates one or more listening timings of the control channel during the open period of each of one or more DRX cycles starting from the next DRX cycle. The first communication node sends the control channel during one or more listening timings of the control channel. The second communication node receives the listening timing indication message and listens to the control channel according to one or more listening timings indicated by the listening timing indication message.

[0146] Optionally, the first communication node configures or indicates at least one of the following for the second communication node: the start time and duration of the listening timing indication information. For example, configuring or indicating the start time and duration of the listening timing indication information; or, for example, pre-configuring or pre-defining one of the start time and duration of the listening timing indication information, and configuring or indicating the other of the start time and duration of the listening timing indication information; for example, the start time is predefined as the next DRX cycle, and the duration is configured or indicated as P DRX cycles.

[0147] Optionally, at least one of the start time and duration of the listening timing indication information can also be determined through pre-configuration or pre-definition.

[0148] Optionally, the listening timing indication information indicates the listening timings within a DRX cycle. The indicated listening timings apply to one or more DRX cycles starting from the next DRX cycle; that is, different DRX cycles can use the same listening timing pattern, meaning that within different DRX cycles, the listening timings have the same start position and duration relative to the DRX cycle. Alternatively, the listening timing indication information can indicate listening timings separately for each of one or more DRX cycles starting from the next DRX cycle. That is, different DRX cycles can use separate listening timing patterns, meaning that within different DRX cycles, the listening timings can have different start positions and durations relative to the DRX cycle. For example, the listening timing indication information includes the number of DRX cycles and the listening timings corresponding to each DRX cycle. The number of listening timings within each DRX cycle can be the same or different.

[0149] Each listening opportunity can be a continuous resource in the time domain.

[0150] As an example, during the activation period of one or more DRX cycles, for each DRX cycle, the listening timing indication information indicates one or more listening opportunities for the control channel. The number of listening opportunities within a DRX cycle can be pre-configured, predefined, or configured through higher-layer signaling.

[0151] In this example, the first communication node sends a listening timing indication message to the second communication node. The listening timing indication message indicates one or more listening opportunities for the control channel during the On Duration time of each DRX cycle, starting from the next DRX cycle.

[0152] Figure 6 is a schematic diagram illustrating an embodiment of indicating listening opportunities within multiple DRX cycles. As shown in Figure 6, for one DRX cycle, the listening opportunity indication information indicates one listening opportunity. Similarly, for one DRX cycle, the listening opportunity indication information can also indicate multiple listening opportunities. The number of listening opportunities within one DRX cycle is pre-configured or predefined, or configured by the first communication node to the second communication node via higher-layer signaling.

[0153] In one example, the listening timing indication information indicates the listening timing within a DRX cycle. The indicated listening timing applies to one or more DRX cycles starting from the next DRX cycle. That is, different DRX cycles use the same listening timing pattern, meaning that within different DRX cycles, the listening timing has the same start position and duration relative to the DRX cycle. For example, at least one of the start effective time and effective duration of the listening timing indication information is configured or indicated to the second communication node by the first communication node, or the start effective time and effective duration of the listening timing indication information are pre-configured or predefined.

[0154] In another example, the listening timing indication information indicates the listening timing for each of one or more DRX cycles starting from the next DRX cycle. For example, the listening timing indication information includes the number of DRX cycles and the listening timing corresponding to each DRX cycle. The number of listening timings within each DRX cycle can be the same or different.

[0155] As an example, during the activation period of one or more DRX cycles, for each DRX cycle, the listening opportunity indication information indicates one or more listening opportunities for the control channel, and the number of listening opportunities within a DRX cycle is dynamically indicated.

[0156] In this example, the first communication node sends a listening timing indication message to the second communication node. The listening timing indication message indicates one or more listening opportunities for the control channel during the On Duration time of each DRX cycle, starting from the next DRX cycle.

[0157] Figure 7 is a schematic diagram illustrating an embodiment that indicates listening opportunities within multiple DRX cycles. As shown in Figure 7, the first listening opportunity indication information indicates two listening opportunities per DRX cycle, and the second listening opportunity indication information indicates one listening opportunity per DRX cycle. The number of listening opportunities within one DRX cycle is dynamically indicated by the first communication node to the second communication node. Exemplarily, the number of listening opportunities can be explicitly or implicitly indicated by the listening opportunity indication information, or jointly indicated by higher-layer signaling and the listening opportunity indication information.

[0158] In one example, the listening timing indication information indicates the listening timing within a DRX cycle, and the indicated listening timing applies to one or more DRX cycles starting from the next DRX cycle. That is, different DRX cycles use the same listening timing pattern. For example, at least one of the start effective time and effective duration of the listening timing indication information is configured or indicated to the second communication node by the first communication node, or the start effective time and effective duration of the listening timing indication information are pre-configured or predefined.

[0159] In another example, the listening timing indication information indicates the listening timing for each of one or more DRX cycles starting from the next DRX cycle. For example, the listening timing indication information indicates the number of DRX cycles and the listening timing corresponding to each DRX cycle. The number of listening timings within each DRX cycle can be the same or different.

[0160] In one embodiment, the listening timing indication information is used to indicate the listening timing of the control channel during the current DRX cycle's open period.

[0161] In this embodiment, the first communication node sends a listening timing indication message, wherein the listening timing indication message indicates one or more listening timings of the control channel during the current DRX cycle's open period. The first communication node sends the control channel during one or more listening timings of the control channel. The second communication node receives the listening timing indication message and listens to the control channel according to one or more listening timings indicated by the listening timing indication message.

[0162] The current DRX period refers to the DRX period in which the listening opportunity indication information was detected; that is, the current DRX period refers to the DRX period in which the listening opportunity indication information was transmitted. Each listening opportunity is a continuous resource in the time domain.

[0163] Optionally, the listening timing indication information is sent some time after the start of the DRX cycle.

[0164] As an example, during the open period of a DRX cycle, the listening opportunity indication information indicates one or more listening opportunities for the control channel. The number of listening opportunities within a DRX cycle is pre-configured, predefined, or configured via higher-layer signaling.

[0165] In this example, the first communication node sends a listening opportunity indication message to the second communication node. The listening opportunity indication message indicates one or more listening opportunities of the control channel within the On Duration time (i.e., the open period) of the current DRX cycle.

[0166] Figure 8 is a schematic diagram illustrating an indication of a listening opportunity within the on-duration period of a current DRX cycle, according to an embodiment. As shown in Figure 8, the listening opportunity indication information indicates a listening opportunity of the control channel within the on-duration time of its DRX cycle. Similarly, for a DRX cycle, the listening opportunity indication information can also indicate multiple listening opportunities. The number of listening opportunities within a DRX cycle is pre-configured, predefined, or configured by the first communication node to the second communication node via higher-layer signaling.

[0167] As an example, during the open period of a DRX cycle, the listening opportunity indication information indicates one or more listening opportunities for the control channel, and the number of listening opportunities within a DRX cycle is dynamically indicated.

[0168] In this example, the first communication node sends a listening opportunity indication message to the second communication node. The listening opportunity indication message indicates one or more listening opportunities of the control channel within the On Duration time (i.e., the open period) of the current DRX cycle.

[0169] Figure 9 is a schematic diagram illustrating another method for indicating listening opportunities during the activation period in different DRX cycles, according to one embodiment. As shown in Figure 9, for the first DRX cycle, the listening opportunity indication information indicates two listening opportunities, and for the second DRX cycle, the listening opportunity indication information indicates one listening opportunity. The number of listening opportunities within a DRX cycle is dynamically indicated by the first communication node to the second communication node. Exemplarily, the number of listening opportunities can be indicated by the listening opportunity indication information, such as an explicit indication or an implicit indication, or the number of listening opportunities can be jointly indicated by higher-layer signaling and the listening opportunity indication information.

[0170] In one embodiment, the listening timing indication information is used to indicate the listening timing of the control channel during the open period of one or more DRX cycles starting from the current DRX cycle.

[0171] In this embodiment, the first communication node sends a listening timing indication message, wherein the listening timing indication message indicates one or more listening timings of the control channel during the open period of each of one or more DRX cycles starting from the current DRX cycle. The first communication node sends the control channel during one or more listening timings of the control channel. The second communication node receives the listening timing indication message and listens to the control channel according to one or more listening timings indicated by the listening timing indication message.

[0172] Optionally, the first communication node configures or instructs the second communication node to at least one of the following: the start time and duration of the listening timing indication information.

[0173] Optionally, at least one of the start time and duration of the listening timing indication information can also be determined through pre-configuration or pre-definition.

[0174] For example, the start time and duration of the listening timing indication information can be configured or indicated; for example, one of the start time and duration of the listening timing indication information can be pre-configured or pre-defined, and the other of the start time and duration of the listening timing indication information can be configured or indicated; for example, the start time can be pre-defined as the current DRX cycle, and the duration of the indication can be configured or indicated as P DRX cycles.

[0175] Optionally, the listening timing indication information indicates the listening timings within a DRX cycle. The indicated listening timings apply to one or more DRX cycles starting from the current DRX cycle; that is, different DRX cycles use the same listening timing pattern, meaning that within different DRX cycles, the listening timings have the same start position and duration relative to the DRX cycle. Alternatively, the listening timing indication information indicates a listening timing for each of one or more DRX cycles starting from the current DRX cycle. For example, the listening timing indication information includes the number of DRX cycles and the listening timings corresponding to each DRX cycle. The number of listening timings within each DRX cycle can be the same or different.

[0176] The current DRX cycle can refer to the DRX cycle in which the listening timing indication information is detected.

[0177] Each listening opportunity is a contiguous resource in the time domain.

[0178] As an example, during the activation period of one or more DRX cycles, for each DRX cycle, the listening timing indication information indicates one or more listening opportunities for the control channel. The number of listening opportunities within a DRX cycle is pre-configured, predefined, or configured through higher-layer signaling.

[0179] In this example, the first communication node sends a listening timing indication message to the second communication node. The listening timing indication message indicates one or more listening opportunities for the control channel during the On Duration time of each DRX cycle in one or more DRX cycles starting from the current DRX cycle.

[0180] Figure 10 is a schematic diagram illustrating another embodiment that indicates listening opportunities within multiple DRX cycles. As shown in Figure 10, for one DRX cycle, the listening opportunity indication information indicates one listening opportunity. Similarly, for one DRX cycle, the listening opportunity indication information can also indicate multiple listening opportunities. The number of listening opportunities within one DRX cycle is pre-configured, predefined, or configured by the first communication node to the second communication node via higher-layer signaling.

[0181] In one instance, the listen timing indication information indicates the listen timing within a DRX cycle. The indicated listen timing applies to one or more DRX cycles starting from the current DRX cycle, meaning that the same listen timing pattern is used within the On Duration time of different DRX cycles.

[0182] In another example, the listening timing indication information indicates the listening timing for each of one or more DRX cycles starting from the current DRX cycle. For example, the listening timing indication information includes the number of DRX cycles and the listening timing corresponding to each DRX cycle. The number of listening timings within each DRX cycle can be the same or different.

[0183] As an example, during the activation period of one or more DRX cycles, for each DRX cycle, the listening opportunity indication information indicates one or more listening opportunities for the control channel, and the number of listening opportunities within a DRX cycle is dynamically indicated.

[0184] In this example, the first communication node sends a listening timing indication message to the second communication node. The listening timing indication message indicates one or more listening opportunities for the control channel during the On Duration time of each DRX cycle, starting from the current DRX cycle.

[0185] Figure 11 is a schematic diagram illustrating another embodiment of indicating listening opportunities within multiple DRX cycles. As shown in Figure 11, the first listening opportunity indication information indicates two listening opportunities per DRX cycle, and the second listening opportunity indication information indicates one listening opportunity per DRX cycle. The number of listening opportunities within one DRX cycle is dynamically indicated by the first communication node to the second communication node. Exemplarily, the number of listening opportunities can be indicated by the listening opportunity indication information, for example, explicitly indicated or implicitly indicated, or jointly indicated by higher-layer signaling and the listening opportunity indication information.

[0186] In one example, the listener timing indication information indicates the listener timing within a DRX cycle. The indicated listener timing applies to one or more DRX cycles starting from the current DRX cycle. That is, the same listener timing pattern is used within the On Duration time of different DRX cycles.

[0187] In another example, the listening timing indication information indicates the listening timing for each of one or more DRX cycles starting from the current DRX cycle. For example, the listening timing indication information indicates the number of DRX cycles and the listening timing corresponding to each DRX cycle. The number of listening timings within each DRX cycle can be the same or different.

[0188] In one embodiment, the monitoring timing indication information is used to indicate the monitoring timing of the control channel within the DRX cycle. In this embodiment, the monitoring timing of the control channel can be located within the on and off periods of the DRX cycle.

[0189] In this embodiment, the first communication node sends a listening timing indication message, which indicates one or more listening timings for the control channel within one or more DRX cycles. The first communication node transmits the control channel within one or more listening timings. The second communication node receives the listening timing indication message and listens to the control channel according to one or more listening timings indicated by the listening timing indication message.

[0190] Each listening opportunity can be a contiguous resource in the time domain. For example, each listening opportunity consists of N consecutive time units. These time units can be consecutive symbols, time slots, or milliseconds. The current DRX period refers to the DRX period in which the listening opportunity indication information was detected; that is, the current DRX period refers to the DRX period in which the listening opportunity indication information was transmitted.

[0191] One or more DRX cycles include one of the following: the next DRX cycle, one or more DRX cycles starting from the next DRX cycle, the current DRX cycle, and one or more DRX cycles starting from the current DRX cycle.

[0192] Optionally, the first communication node configures or instructs the second communication node to at least one of the following: the start time and duration of the listening timing indication information.

[0193] Optionally, at least one of the start time and duration of the listening timing indication information can also be determined through pre-configuration or pre-definition.

[0194] For example, the start time and duration of the listening timing indication information can be configured or indicated; for example, one of the start time and duration of the listening timing indication information can be pre-configured or pre-defined, and the other of the start time and duration of the listening timing indication information can be configured or indicated; for example, the start time can be pre-defined as the next DRX cycle, and the duration of the indication can be configured or indicated as P DRX cycles.

[0195] Optionally, the listening timing indication information indicates the listening timings within a DRX cycle, and the indicated listening timings apply to one or more DRX cycles starting from the next DRX cycle. That is, different DRX cycles use the same listening timing pattern (i.e., within different DRX cycles, the listening timings have the same start position and duration relative to the DRX cycle); or, the listening timing indication information indicates a separate listening timing for each of the one or more DRX cycles starting from the next DRX cycle. For example, the listening timing indication information includes the number of DRX cycles and the listening timings corresponding to each DRX cycle. The number of listening timings within each DRX cycle can be the same or different.

[0196] Optionally, for a DRX cycle, if the DRX persistence timer is running at the start of the first listening time of the DRX cycle, then the DRX persistence timer is restarted.

[0197] Optionally, for each listening opportunity within a DRX cycle, if the DRX persistence timer is running at the start of the listening opportunity, the DRX persistence timer is restarted.

[0198] In one embodiment, the timing indication information for listening is designed.

[0199] As an example, the listening timing indication information indicates the listening timing in at least one of the following ways:

[0200] Method 1: The monitoring timing indication information is indicated using a bitmap. A DRX period or its start time segment contains M time units, each time unit corresponding to a bit in the bitmap. The value of the bit indicates the monitoring timing. For example, if the start time segment of a DRX period contains M time slots, the bitmap has M bits, where each bit corresponds to one time slot. Slots with a bit value of 1 are included in the monitoring timing. One or more consecutive time slots with a bit value of 1 constitute a monitoring timing. As another example, if the start time segment of a DRX period contains M time units, such as each time unit being 1 / 32 milliseconds, the bit length L of the bitmap can be greater than or equal to M. For instance, the bit length of the bitmap could be the maximum number of time units L in the DRX period. The M least significant bits (or M most significant bits) of the L bits in the bitmap are used to indicate the monitoring timing of that DRX period.

[0201] Method 2: The listening timing indication information indicates one or more listening timings. For each listening timing, the listening timing indication information indicates the start position and duration of the listening timing.

[0202] Method 3: The listening timing indication information indicates one or more listening timings. For each listening timing, the listening timing indication information indicates the start position of the listening timing. The duration of each listening timing is pre-configured, predefined, or configured via higher-layer signaling. For example, the first communication node configures a duration for the second communication node via higher-layer signaling, and this duration applies to all listening timings in all DRX cycles; or for a DRX cycle, the first communication node configures one or more durations for the second communication node via higher-layer signaling, with each duration corresponding to one listening timing; or the first communication node configures one or more durations for the second communication node via higher-layer signaling, and the listening timing indication information indicates a duration that applies to all listening timings in all DRX cycles.

[0203] Method 4: The listening timing indication information indicates one or more listening timings. For each listening timing, the listening timing indication information indicates the start and end positions of the listening timing (i.e., the start position and the end position).

[0204] Method 5: The listening timing indication information indicates one or more listening timings. For listening timings other than the last listening time, the listening timing indication information indicates the start and end positions of the listening timing (e.g., start position and duration, or start position and end position). For the last listening timing, the listening timing indication information indicates the start position of the listening timing. The end position of the listening timing is pre-configured or predefined as the end position of the start period of the DRX cycle, or the duration or end position of the listening timing is pre-configured by the first communication node for the second communication node. When the listening timing indication information indicates a single listening timing, that listening timing can also be considered the last listening timing.

[0205] Method 6: The first communication node configures a list of listening timing patterns for the second communication node via higher-layer signaling. Each listening timing pattern represents a listening timing configuration. Each listening timing pattern in the list has an index, and the listening timing indication information indicates the index of the listening timing pattern.

[0206] Optionally, for a DRX cycle, either method 2 or method 3 above satisfies at least one of the following:

[0207] The listening timing indication information should include the listening timing within the DRX cycle or the DRX cycle's on period.

[0208] If the listening timing indicated by the listening timing information exceeds the range of the DRX cycle or the opening period of the DRX cycle, then only the listening timing included within the DRX cycle or the opening period of the DRX cycle is valid, as shown in Figure 12.

[0209] If the listening timing indicated by the listening timing indication information exceeds the range of the DRX cycle or the opening period of the DRX cycle, the excess part continues to be mapped from the beginning of the DRX cycle, as shown in Figure 13.

[0210] As an example, the listening timing indication information is transmitted via the control channel using a specific control information format. For instance, the listening timing indication information may be contained in a different control information format than the wake-up signal, or it may be contained in the same control information format as the wake-up signal. To enable the second communication node to detect the specific control channel format, the first communication node provides the second communication node with at least one of the following information related to the specific control channel format via higher-layer signaling: Radio Network Temporary Identity (RNTI), search space set, payload size, the position of the listening timing indication information within the payload of the specific control channel format, and the time the second communication node listens for the listening timing indication information according to the search space set.

[0211] In one instance, the second communication node can be a specific UE or a group of UEs.

[0212] In one instance, the listening timing indication information indicates that the listening timing applies (or can be applied to) one or more bandwidth parts (BWPs). Optionally, the first communication node configures the BWP to which the listening timing indicated by the listening timing indication information applies for the second communication node via higher-layer signaling, or the first communication node provides the BWP to which the listening timing indicated by the listening timing indication information applies in the listening timing indication information, or the listening timing indicated by the listening timing indication information applies to the BWP for transmitting the listening timing indication information.

[0213] In one example, the listening timing indication information is a listening timing indication sequence. The first communication node configures the resource location for the second communication node to send the listening timing indication sequence via higher-layer signaling. For a DRX cycle, if the second communication node detects the listening timing indication sequence, it listens to the control channel according to the listening timing indication sequence. The listening timing indication sequence indicates whether to listen to the control channel during the opening period of the current DRX cycle or the next DRX cycle. For example, the second communication node listens to the control channel according to the listening timing indication sequence and DRX configuration parameters. For instance, the listening timing indication sequence is sent on the first K symbols of the DRX cycle (K is an integer greater than or equal to 1). If the second communication node detects the listening timing indication sequence within a DRX cycle, it listens to the control channel during the opening period of that DRX cycle; otherwise, it does not listen to the control channel during the opening period of that DRX cycle, unless the second communication node is waiting for scheduling authorization, an inactive timer is running, a discontinuous receive retransmission timer is running, a random access contention resolution timer is running, or a two-step random access response window is running.

[0214] As an example, the listening behavior of the second communication node includes at least one of the following:

[0215] One monitoring behavior is that, for a DRX cycle, if the second communication node starts the DRX continuous timer and detects the monitoring timing indication information, then the second communication node monitors the control channel at the monitoring timing of the DRX cycle. For example, based on the DRX configuration (or based on the DRX configuration and wake-up signal indication), the second communication node starts the DRX continuous timer in a DRX cycle, and the second communication node receives the monitoring timing indication information sent by the first communication node, indicating that it monitors the control information in the last two time slots during the opening period of the DRX cycle. Then the second communication node only monitors the control channel in the last two time slots during the opening period of the DRX cycle.

[0216] One type of listening behavior is that, for a DRX cycle, if the second communication node does not start the DRX continuous timer, then the second communication node does not listen to the control channel during the listening time of the DRX cycle. For example, if the wake-up signal indicates that the DRX cycle is not woken up (i.e., the DRX continuous timer is not started for the DRX cycle), then the second communication node does not listen to the control channel during the DRX cycle, regardless of whether the second communication node receives the listening time indication information.

[0217] One monitoring behavior is that, for a DRX cycle, if the second communication node has started a DRX persistence timer and at least one of the following conditions is met:

[0218] 1) The second communication node did not detect the eavesdropping timing indication information (e.g., the control channel did not detect the eavesdropping timing indication information);

[0219] 2) The second communication node was not required to detect the eavesdropping timing indication information (e.g., the first communication node did not require the second communication node to detect the control channel for the eavesdropping timing indication information, or resources were not configured for the second communication node to transmit the control channel for the eavesdropping timing indication information).

[0220] 3) If the second communication node does not detect the timing indication information (e.g., does not detect the timing of transmitting the control channel), then the second communication node will listen to the control channel throughout the entire open period of the DRX cycle.

[0221] One monitoring behavior is that, for a DRX cycle, if the second communication node has started a DRX persistence timer and at least one of the following conditions is met:

[0222] 1) The second communication node did not detect the eavesdropping timing indication information (e.g., the control channel did not detect the eavesdropping timing indication information);

[0223] 2) If the second communication node does not detect the timing of the listening timing indication information (for example, if it does not detect the timing of the control channel transmitting the listening timing indication information), then the second communication node does not listen to the control channel during the DRX period.

[0224] As an example, a first communication node indicates to a second communication node the control resources to be monitored / not monitored during a listening period. The control resources to be monitored / not monitored include at least one of the following: a control resource set (CORESET), a search space to be monitored / not monitored, an aggregation level to be monitored / not monitored, and a control information format to be monitored / not monitored. For example, the first communication node indicates to the second communication node that the search space to be monitored during the listening period is s1, and the aggregation level is 1; then the second communication node monitors the control channels with aggregation level 1 in the search space s1 during the listening period. The first communication node can indicate the control resources to be monitored / not monitored during the listening period through higher-layer signaling; or it can jointly indicate the control resources to be monitored / not monitored during the listening period through higher-layer signaling and listening period indication information.

[0225] As an example, within the Monitor Occasion Timer (MO Timer), for a DRX cycle, the second communication node determines whether to monitor the control channel during the monitoring period of the DRX cycle based on whether the DRX persistence timer is enabled. For example, within the MO Timer, for a DRX cycle, if the second communication node enables the DRX persistence timer, then the second communication node monitors the control channel during the monitoring period of the DRX cycle; if the second communication node does not enable the DRX persistence timer, then the second communication node does not monitor the control channel during the DRX cycle. Outside the MO Timer, the second communication node determines whether to monitor the control channel during the DRX cycle based on whether the DRX persistence timer is enabled (i.e., the energy-saving mechanism of this application is not used outside the MO Timer). For example, for a DRX cycle, if the second communication node enables the DRX persistence timer, then the second communication node monitors the control channel during the DRX cycle's active period; if the second communication node does not enable the DRX persistence timer, then the second communication node does not monitor the control channel during the DRX cycle or during the DRX cycle's active period.

[0226] In the embodiments of this application, "whether the timer is on" and "whether the timer is running" are equivalent descriptions, "within the MO Timer" and "the MO Timer is running" are equivalent descriptions, and "outside the MO Timer" and "the MO Timer is not running" are equivalent descriptions. Equivalent descriptions can be substituted for each other.

[0227] In one instance, the MO Timer is determined by pre-configuration or pre-definition, or configured or indicated to the second communication node by the first communication node.

[0228] In one instance, the MO Timer is enabled in at least one of the following ways:

[0229] After receiving the listening timing indication information, the second communication node starts or restarts the listening timing timer after a first time interval (Toffset1);

[0230] The second communication node periodically turns on the MO Timer;

[0231] The listening timing timer restarts after a second time interval (Toffset2) following its expiration.

[0232] Specifically, Toffset1 is determined through pre-configuration or pre-definition, or configured or indicated to the second communication node by the first communication node; Toffset2 is determined through pre-configuration or pre-definition, or configured or indicated to the second communication node by the first communication node; the MO Timer period and the offset time of the MO Timer start time relative to the start position of the MO Timer period are determined through pre-configuration or pre-definition, or configured or indicated to the second communication node by the first communication node. The length of the MO Timer is a multiple of the DRX period, or an arbitrary duration.

[0233] In one embodiment, the first communication node may also send an instruction to the second communication node to cancel the listening opportunity. The instruction to cancel the listening opportunity is used to cancel one or more listening opportunities within one or more DRX cycles.

[0234] This application also provides a monitoring timing indication device. Figure 14 is a schematic diagram of a monitoring timing indication device according to an embodiment. As shown in Figure 14, the monitoring timing indication device includes:

[0235] The first transmitting module 310 is configured to transmit listening timing indication information, which is used to indicate at least one listening timing for the control channel within at least one discontinuous reception DRX period.

[0236] The second transmitting module 320 is configured to transmit a control channel during the at least one listening opportunity.

[0237] The monitoring timing indication device in this embodiment makes the indication and configuration of monitoring timing more flexible by sending monitoring timing indication information. For DRX cycles that require monitoring the control channel, the second communication node does not need to wake up at the beginning of the DRX cycle, and the wake-up time does not necessarily have to last for the entire on-time period. Instead, it can be flexibly indicated and adjusted according to actual needs. Based on this, the second communication node can be avoided from being woken up at unnecessary times, avoiding unnecessary monitoring, thereby reducing power waste and achieving more efficient terminal energy saving.

[0238] In one embodiment, the at least one DRX cycle includes at least one of the following:

[0239] Current DRX cycle;

[0240] At least one DRX cycle starting from the current DRX cycle;

[0241] The next DRX cycle after the current DRX cycle;

[0242] At least one DRX cycle starting from the next DRX cycle;

[0243] The current DRX cycle refers to the DRX cycle in which the monitoring timing indication information is transmitted. The next DRX cycle refers to the first DRX cycle after the current DRX cycle, that is, the DRX cycle following the current DRX cycle.

[0244] In one embodiment, for a single DRX cycle, the number of listening opportunities within the DRX cycle satisfies at least one of the following:

[0245] Pre-configured;
