Description

Communication method and device, terminal equipment and network equipment

This invention claims priority from the prior application No. 2024104042986 filed on April 3, 2024, entitled “Communication Method and Apparatus, Terminal Equipment and Network Equipment”. The contents of the aforementioned prior application are incorporated herein by reference.

Technical Field

The present application relates to the field of communication technology, and in particular to a communication method and apparatus, terminal equipment, and network equipment.

Background Art

In order to reduce the power consumption of terminal devices, a low-power wake-up signal (LP-WUS) has been introduced. The terminal device may include a main radio (MR) and a low-power wake-up signal receiver (LP-WUS receiver). The MR of the terminal device is used for normal data communication, and the low-power wake-up signal receiver is used to receive low-power wake-up signals. When the terminal device has no business or data scheduling, the MR of the terminal device can enter a sleep state and no longer perform physical downlink control channel (PDCCH) monitoring. When business arrives or data is scheduled on the terminal device, the network can use LP-WUS to wake up the MR of the terminal device to perform PDCCH monitoring. In the radio resource control (RRC) connection state, how the low-power wake-up signal instructs the terminal device to perform PDCCH monitoring is a problem that needs to be solved.

Then, the first low-power wake-up signal is used to indicate to the terminal device whether to monitor the PDCCH on each of the N service cells of the M service cells, so that the terminal device monitors the PDCCH on each of the N service cells according to the instruction of the network device, and avoids the terminal device from performing unnecessary PDCCH monitoring as much as possible, thereby helping to save power consumption of the terminal device.

【Access network equipment】

Access network equipment is referred to as a radio access network (RAN). The RAN, comprised of multiple 5G-RAN nodes, implements wireless physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management. The 5G-RAN connects to the UPF via the user plane interface (N3) for data transmission between terminal devices. The 5G-RAN establishes a control plane signaling connection with the mobility management function (AMF) via the control plane interface (N2) to implement functions such as radio access bearer control. RAN can be any device with wireless transceiver functions, including but not limited to 5G node base (gNB), evolutionary node base (eNB), wireless access point (WiFi AP), world interoperability for microwave access base station (WiMAX BS), transmission receiving point (TRP), wireless relay node, wireless backhaul node, master node (MN) in dual-connection architecture, secondary node or secondary node (SN) in dual-connection architecture, etc.

In addition, the access network device may refer to a device used to communicate with a terminal device.

In 5G NR, the functions of access network equipment are divided into two parts, known as the centralized unit (CU)-distributed unit (DU) separation. From a protocol stack perspective, the CU includes the radio resource control (RRC) layer and packet data convergence protocol (PDCP) layer of the LTE base station, while the DU includes the radio link control (RLC) layer, media access control (MAC) layer, and physical (PHY) layer of the LTE base station. In a typical 5G base station deployment, the CU and DU can be physically connected via optical fiber, and logically there is a specially defined F1 interface for communication between the CU and DU. From a functional perspective, the CU is primarily responsible for radio resource control and configuration, cross-cell mobility management, and bearer management. The DU is primarily responsible for scheduling, physical signal generation, and transmission.

Optionally, the access network device can be a macro base station, a micro base station, a pico base station, a small station, a relay station, a balloon station, etc.

Core network equipment

Core network equipment may include network elements that provide various functions. "Network element" may also be referred to as an entity, device, apparatus, or module, without specific limitation. Furthermore, for ease of understanding and explanation, the term "network element" is omitted in some descriptions. For example, a network exposure function (NEF) network element is referred to as NEF. In this case, "NEF" should be understood as either a NEF network element or a NEF entity. The following descriptions of identical or similar situations are omitted.

For example, core network equipment may include a mobility management entity (MME), a broadcast multicast service center (BMSC), etc., or may include corresponding functional entities in the 5G system, such as the core network control plane (CP) or user plane (UP) network functions, etc. The core network control plane can also be understood as the control plane function (CPF) entity of the core network.

The following describes the various network elements included in the core network equipment.

The session management function (SMF) is responsible for the control plane functions of terminal device session management, including the selection and control of user plane function (UPF), Internet protocol (IP) address allocation, session QoS management, policy and charging control (PCC) policy, etc.

The user plane function (UPF) can serve as the anchor point for the protocol data unit (PDU) session connection. It is responsible for data packet filtering, data transmission/forwarding, rate control, generation of billing information, etc. for terminal devices, and provides connection with the data network (DN).

The policy control function (PCF) can provide configuration policy information for terminal devices and provide policy information for network control plane elements (such as SMF) to manage and control terminal devices; it can also generate terminal device access policies and QoS flow control policies.

The AF can interact with network elements in the core network to provide some services. For example, the AF interacts with the PCF to control service policies, interacts with the NEF to obtain some network capability information or provide some application information to the network, and provides some data network access point information to the PCF to generate routing information for corresponding data services.

NEF can be responsible for providing some network-related status information to application services.

The Authentication Server Function (AUSF) can implement 3GPP and non-3GPP access authentication.

Unified Data Management (UDM), unified data management functions, 3GPP AKA authentication, user identification, access authorization, registration, mobility, subscription, SMS management, etc.

The network slice selection function (NSSF) can determine the network slice instance that the terminal device is allowed to access based on the slice selection auxiliary information, contract information, etc. of the terminal device.

The network repository function (NRF) can be a new function that provides registration and discovery capabilities, enabling network functions (NFs) to discover each other and communicate through API interfaces.

Unified data management (UDM) can be responsible for the management of user identification, contract data, authentication data, user service network element registration management, etc.

The unified data repository (UDR) can be used by UDM to store subscription data or read subscription data and by PCF to store policy data or read policy data.

The network data analytics function (NWDAF) can provide network analysis services based on the request data of network services.

The network slice specific authentication and authorization function (NSSAAF) can be used to provide authentication and authorization for a specific network slice.

It should be noted that terminal devices are wirelessly connected to access network devices, and access network devices are wirelessly or wiredly connected to core network devices. Access network devices and core network devices can be independent and distinct physical devices, or they can integrate the functions of core network devices and the logical functions of access network devices into the same physical device, or they can integrate some core network device functions and some access network device functions into a single physical device.

For example, Figure 2 is a schematic diagram of the architecture of another communication system according to an embodiment of the present application. The naming of each network element included in Figure 2 is only a name, and the name does not limit the function of the network element itself. In 5G networks and other future networks, the above-mentioned network elements may also have other names, and this is not specifically limited. For example, in a 6G network, some or all of the above-mentioned network elements may use the terminology used in 5G, or may have other names, etc., which are uniformly explained here and will not be repeated below.

In addition, the network elements in Figure 2 do not necessarily need to exist simultaneously, and the required network elements can be determined based on demand. The connection relationship between the network elements in Figure 2 is not unique and can be adjusted based on demand. It is understood that the above-mentioned network elements or functions can be network components in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform).

Of course, FIG2 is merely an example of a network architecture of a communication system and does not constitute a limitation on the network architecture of the communication system in the embodiment of the present application.

The communication system has been described above. The low-power wake-up signal mechanism of this embodiment will be specifically described below.

In order to reduce the power consumption of terminal devices, low-power wake-up signals are currently introduced. When the terminal device has data scheduling or service arrival, the MR of the terminal device can enter a sleep state to achieve the goal of energy saving. While the MR of the terminal device is in the sleep state, the low-power wake-up signal receiver of the terminal device can receive the low-power wake-up signal sent by the network device. From the perspective of the network device side, when the terminal device has data scheduling or service arrival, the network device can wake up the MR of the terminal device through a low-power wake-up signal to perform PDCCH monitoring. From the perspective of the terminal device side, while the MR of the terminal device is in the sleep state, the low-power wake-up signal receiver of the terminal device determines whether to perform PDCCH monitoring by receiving the low-power wake-up signal sent by the network device. Among them, the sleep state includes a deep sleep state, a light sleep state, and a micro-sleep state.

The MR can have a complete RF and baseband processing architecture and can be viewed as a module/circuit for transmitting and receiving signals/channels other than the LPWUS. Of course, the MR can also be referred to as a main transceiver, an overall transceiver, or a regular transceiver, without specific limitation.

After the terminal device turns on MR, the terminal device may need to monitor PDCCH, etc., which will generate certain power consumption. For example, the power consumption includes the power consumption of the terminal device switching from sleep state to wake-up state and the power consumption of the terminal device monitoring PDCCH.

Terminal devices in the RRC connected state can use the connected-discontinuous reception (C-DRX) mechanism to monitor the PDCCH to reduce power consumption.

In addition, this embodiment considers the scenario of carrier aggregation (CA). Carrier aggregation is a technology that aggregates multiple carriers (also known as component carriers (CC)) to support a larger transmission bandwidth. For terminal devices in the RRC connected state, the multiple serving cells in the carrier aggregation are composed of primary cells (PCells) and secondary cells (SCells).

In carrier aggregation scenarios, a terminal device in the RRC connected state can configure multiple carriers for data transmission, with each carrier corresponding to a serving cell. Generally, a terminal device in the RRC connected state may need to monitor the PDCCH on each of the multiple serving cells in the carrier aggregation, which results in higher power consumption of the terminal device, especially when the number of serving cells in the carrier aggregation is large.

Based on this, this embodiment considers using a low-power wake-up signal to indicate to the terminal device whether to monitor or not monitor the PDCCH on all or some of the serving cells of the carrier aggregation. In this way, the terminal device can use the low-power wake-up signal to monitor the PDCCH on the serving cells of the carrier aggregation according to the instruction of the network device, thereby avoiding unnecessary monitoring of the PDCCH by the terminal device as much as possible, thereby saving power consumption of the terminal device.

The following embodiment is specifically described using the example of the number of serving cells of carrier aggregation being M, and the value of M being a positive integer. As shown in FIG3 , FIG3 is a flow chart of a communication method according to an embodiment of the present application, which specifically includes the following steps:

S310. The network device sends first information, where the first information is used to configure a low-power wake-up signal resource.

Correspondingly, the terminal device receives the first information.

S320. The network device sends a first low-power wake-up signal on the low-power wake-up signal resource configured by the first information, where the first low-power wake-up signal is used to instruct the terminal device to monitor or not monitor the PDCCH on each of the N serving cells.

Correspondingly, the terminal device receives the first low-power wake-up signal on the low-power wake-up signal resource configured by the first information.

Among them, the N service cells are N service cells among the M service cells of carrier aggregation, the value of N is a positive integer, and the value of M is not less than the value of N.

For example, taking the value of M as 3 as an example, if the value of N is 1, the first low-power wake-up signal is used to instruct the terminal device to monitor or not monitor PDCCH on one of the three service cells in the carrier aggregation; if the value of N is 2, the first low-power wake-up signal is used to instruct the terminal device to monitor or not monitor PDCCH on two of the three service cells in the carrier aggregation; if the value of N is 3, the first low-power wake-up signal is used to instruct the terminal device to monitor or not monitor PDCCH on the three service cells in the carrier aggregation.

It can be seen that for a terminal device in an RRC connected state, when the terminal device configures carrier aggregation and the number of carrier aggregated service cells is M, this embodiment implements the network configuration of low-power wake-up signal resources through the first information, so as to transmit the first low-power wake-up signal through the low-power wake-up signal resources. Then, the first low-power wake-up signal is used to indicate to the terminal device whether to monitor the PDCCH on each of the N service cells of the M service cells, so that the terminal device monitors the PDCCH on each of the N service cells according to the instruction of the network device, thereby avoiding the terminal device from executing unnecessary operations as much as possible, thereby helping to save power consumption of the terminal device.

In some possible examples, the first information can be carried by system information (such as system information block 1 (SIB1) or other SIBs, etc.), RRC signaling, MAC signaling or downlink control information (DCI), etc.

The following embodiment specifically describes the low-power wake-up signal resource configured by the first information.

This embodiment considers that the low-power wake-up signal resource configured by the first information can be associated with M serving cells. In other words, each of the M serving cells is associated with a low-power wake-up signal resource, and different serving cells can be associated with the same or different low-power wake-up signal resources. In addition, the low-power wake-up signal resource configured by the first information may not be associated with M serving cells.

The following describes in detail how the low-power wake-up signal resources configured by the first information are associated with M serving cells.

Since each of the M service cells is associated with a low-power wake-up signal resource, when the network device sends a low-power wake-up signal on a certain low-power wake-up signal resource, the low-power wake-up signal can be used to instruct the terminal device to monitor or not monitor the PDCCH on the service cell associated with the low-power wake-up signal resource.

For example, taking the value of M as 3, the three service cells of the carrier aggregation are service cell 1, service cell 2 and service cell 3, and the low-power wake-up signal resources configured by the first information include low-power wake-up signal resource 1, low-power wake-up signal resource 2 and low-power wake-up signal resource 3.

If the network device configures serving cell 1 to be associated with low-power wake-up signal resource 1, and serving cell 2 and serving cell 3 to be associated with low-power wake-up signal resource 2, then when the network device sends low-power wake-up signal 1 on low-power wake-up signal resource 1, low-power wake-up signal 1 is used to instruct the terminal device to monitor or not monitor the PDCCH on serving cell 1; at this time, if low-power wake-up signal 1 is the first low-power wake-up signal, then serving cell 1 is the N serving cells. When the network device sends low-power wake-up signal 2 on low-power wake-up signal resource 2, low-power wake-up signal 2 is used to instruct the terminal device to monitor or not monitor the PDCCH on serving cell 2 and serving cell 3; at this time, if low-power wake-up signal 2 is the first low-power wake-up signal, then serving cell 2 and serving cell 3 are the N serving cells.

If the network device configures service cell 1 to be associated with low-power wake-up signal resource 1, service cell 2 to be associated with low-power wake-up signal resource 2, and service cell 3 to be associated with low-power wake-up signal resource 3, then when the network device sends low-power wake-up signal 1 on low-power wake-up signal resource 1, low-power wake-up signal 1 is used to instruct the terminal device to monitor or not monitor PDCCH on service cell 1; when the network device sends low-power wake-up signal 2 on low-power wake-up signal resource 2, low-power wake-up signal 2 is used to instruct the terminal device to monitor or not monitor PDCCH on service cell 2; when the network device sends low-power wake-up signal 3 on low-power wake-up signal resource 3, low-power wake-up signal 3 is used to instruct the terminal device to monitor or not monitor PDCCH on service cell 3.

Based on this, in the above Figure 3, it is assumed that the low-power wake-up signal resource associated with N service cells in the low-power wake-up signal resource configured by the first information is the "first low-power wake-up signal resource". In this way, the network device in the above S320 sends the first low-power wake-up signal on the low-power wake-up signal resource configured by the first information, including: the network device sends the first low-power wake-up signal on the first low-power wake-up signal resource.

Correspondingly, the terminal device receives the first low-power wake-up signal on the first low-power wake-up signal resource.

It can be seen that if each of the M service cells is associated with a low-power wake-up signal resource, when the network device wants to indicate to the terminal device whether to monitor the PDCCH on N service cells, the network device needs to send a first low-power wake-up signal on the low-power wake-up signal resources associated with the N service cells (i.e., the first low-power wake-up signal resource) so as to indicate to the terminal device whether to monitor the PDCCH on the N service cells through the first low-power wake-up signal.

In "Solution 1", how to associate the low-power wake-up signal resources configured by the first information with M serving cells is described in detail from "Method 1" and "Method 2" respectively.

Method 1

In "Method 1," the first information includes at least one set of low-power wake-up signal resource configuration parameters. That is, the network device configures at least one set of low-power wake-up signal resource configuration parameters and the serving cell associated with each set of the at least one set of low-power wake-up signal resource configuration parameters for the terminal device.

Each set of low-power wake-up signal resource configuration parameters is associated with one or more serving cells among the M serving cells, and each set of low-power wake-up signal resource configuration parameters is used to configure low-power wake-up signal resources for the associated serving cell.

For example, taking the value of M as 3 and the network device configured with two sets of low-power wake-up signal resource configuration parameters as an example, the three serving cells of carrier aggregation are serving cell 1, serving cell 2, and serving cell 3. If the network device configures the first set of low-power wake-up signal resource configuration parameters to be associated with serving cell 1, and the first set of low-power wake-up signal resource configuration parameters is used to configure low-power wake-up signal resource 1, then serving cell 1 is associated with low-power wake-up signal resource 1; if the network device configures the second set of low-power wake-up signal resource configuration parameters to be associated with serving cell 2 and serving cell 3, and the second set of low-power wake-up signal resource configuration parameters is used to configure low-power wake-up signal resource 2, then serving cell 2 and serving cell 3 are associated with low-power wake-up signal resource 2.

Based on this, in the above Figure 3, the first low-power wake-up signal resource configuration parameter is used to configure the first low-power wake-up signal resource, and the first low-power wake-up signal resource configuration parameter is a set of low-power wake-up signal resource configuration parameters associated with N service cells in the at least one set of low-power wake-up signal resource configuration parameters.

In some possible examples, each set of low-power wake-up signal resource configuration parameters is used to configure at least one of the following: the time domain resource location of the low-power wake-up signal, the frequency domain resource location of the low-power wake-up signal, the carrier where the low-power wake-up signal resource is located, or the narrowband where the low-power wake-up signal resource is located.

In this way, this embodiment can configure the low-power wake-up signal resources according to each set of low-power wake-up signal resource configuration parameters.

It should be noted that the low-power wake-up signal time domain resource location may refer to the location of the time domain resource used to carry the low-power wake-up signal, or the location of the low-power wake-up signal time domain resource. For example, the system frame, time slot or symbol where the time domain resource used to carry the low-power wake-up signal is located. In addition, the low-power wake-up signal time domain resource may include a low-power wake-up signal occasion or a low-power wake-up signal time domain monitoring occasion.

The low-power wake-up signal frequency domain resource location may refer to the location of the frequency domain resource used to carry the low-power wake-up signal, or the location of the frequency domain resource of the low-power wake-up signal. For example, the resource block (RB), resource element (RE), or subcarrier where the frequency domain resource used to carry the low-power wake-up signal is located.

The carrier where the low-power wake-up signal resource is located may refer to the carrier where the resource for transmitting the low-power wake-up signal is located. The narrowband where the low-power wake-up signal resource is located may refer to the carrier where the resource for transmitting the low-power wake-up signal is located.

In some possible examples, each set of low-power wake-up signal resource configuration parameters is used to configure periodic or aperiodic low-power wake-up signal time-domain monitoring opportunities. The periods of the low-power wake-up signal time-domain monitoring opportunities configured by different sets of low-power wake-up signal resource configuration parameters may be the same or different.

For example, take the value of M as 3, the network device is configured with two sets of low-power wake-up signal resource configuration parameters, and each set of low-power wake-up signal resource configuration parameters is used to configure the periodic low-power wake-up signal time domain monitoring opportunity, as shown in Figure 4. In Figure 4, the three serving cells of carrier aggregation are serving cell 1, serving cell 2, and serving cell 3. Among them, the first set of low-power wake-up signal resource configuration parameters is used to configure the periodic low-power wake-up signal time domain monitoring opportunity, and the first set of low-power wake-up signal resource configuration parameters is associated with serving cell 1; the second low-power wake-up signal resource configuration parameters is used to configure the periodic low-power wake-up signal time domain monitoring opportunity, and the second set of low-power wake-up signal resource configuration parameters is associated with serving cell 2 and serving cell 3.

Method 2

In "Method 2," the first information includes a set of low-power wake-up signal resource configuration parameters, and the set of low-power wake-up signal resource configuration parameters is used to configure multiple low-power wake-up signal time-domain monitoring opportunities. In other words, the network device configures a set of low-power wake-up signal resource configuration parameters for the terminal device, and uses the set of low-power wake-up signal resource configuration parameters to configure multiple low-power wake-up signal time-domain monitoring opportunities for the terminal device.

Each of the multiple low-power wake-up signal time domain monitoring opportunities is associated with one or more serving cells among the M serving cells.

For example, taking the value of M as 3 and the network device configured with a set of low-power wake-up signal resource configuration parameters as an example, the three serving cells of carrier aggregation are serving cell 1, serving cell 2, and serving cell 3. The low-power wake-up signal time domain monitoring opportunities configured by the set of low-power wake-up signal resource configuration parameters are low-power wake-up signal time domain monitoring opportunity 1, low-power wake-up signal time domain monitoring opportunity 2, and low-power wake-up signal time domain monitoring opportunity 3. Among them, low-power wake-up signal time domain monitoring opportunity 1 is associated with serving cell 1, low-power wake-up signal time domain monitoring opportunity 2 is associated with serving cell 2, and low-power wake-up signal time domain monitoring opportunity 3 is associated with serving cell 3.

Based on this, in FIG3 above, one of the multiple low-power wake-up signal time domain monitoring opportunities is a first low-power wake-up signal resource, and the one low-power wake-up signal time domain monitoring opportunity is associated with N serving cells.

In some possible examples, the network device can explicitly configure the terminal device through system information (such as SIB1 or other SIBs, etc.), RRC signaling, MAC signaling or DCI, etc. to associate each of the multiple low-power wake-up signal time domain monitoring occasions with one or more service cells among the M service cells.

In some possible examples, each low-power wake-up signal time domain monitoring opportunity in the multiple low-power wake-up signal time domain monitoring opportunities may correspond to a unique opportunity number, and each service cell in the M service cells may correspond to a unique cell number. Since the network device or the terminal device can know the opportunity number corresponding to each low-power wake-up signal time domain monitoring opportunity in the multiple low-power wake-up signal time domain monitoring opportunities and the cell number corresponding to each service cell in the M service cells, the network device or the terminal device can determine the service cell associated with the low-power wake-up signal time domain monitoring opportunity based on the opportunity number and the cell number, thereby implicitly configuring each low-power wake-up signal time domain monitoring opportunity in the multiple low-power wake-up signal time domain monitoring opportunities to be associated with one of the M service cells.

For example, the opportunity number m corresponding to the low-power wake-up signal time-domain monitoring opportunity and the cell number n corresponding to the serving cell associated with the low-power wake-up signal time-domain monitoring opportunity satisfy the following formula: m mod n = 0. It should be noted that since both the opportunity number m and the cell number n are unique, according to the above formula, each low-power wake-up signal time-domain monitoring opportunity can only be associated with one serving cell.

Based on this, in Figure 3 above, the timing number i corresponding to the first low-power wake-up signal time-domain monitoring timing satisfies the following formula: i mod j = 0, where j represents the cell number corresponding to the serving cell among the N serving cells. Thus, the network device or terminal device can determine, based on the above formula, that the first low-power wake-up signal time-domain monitoring timing is associated with N serving cells, where N is 1.

In some possible examples, the set of low-power wake-up signal resource configuration parameters is used to configure at least one of the following: the time domain positions of the multiple low-power wake-up signal time domain monitoring opportunities, the frequency domain positions of the multiple low-power wake-up signal time domain monitoring opportunities, the carriers where the multiple low-power wake-up signal time domain monitoring opportunities are located, and the narrowband where the multiple low-power wake-up signal time domain monitoring opportunities are located.

In this way, this embodiment can configure the multiple low-power wake-up signal time-domain monitoring opportunities according to the set of low-power wake-up signal resource configuration parameters.

In some possible examples, the multiple low-power wake-up signal time-domain monitoring opportunities may be periodic or non-periodic low-power wake-up signal time-domain monitoring opportunities.

For example, take the value of M as 3, the network device configures a set of low-power wake-up signal resource configuration parameters, and the set of low-power wake-up signal resource configuration parameters is used to configure the periodic low-power wake-up signal time domain monitoring opportunity, as shown in Figure 5. In Figure 5, the three serving cells of the carrier aggregation are serving cell 1, serving cell 2, and serving cell 3. Then, the network device explicitly configures the low-power wake-up signal time domain monitoring opportunity associated with serving cell 1, serving cell 2, and serving cell 3 through signaling.

For another example, take the value of M as 2, the network device configures a set of low-power wake-up signal resource configuration parameters, and the set of low-power wake-up signal resource configuration parameters is used to configure periodic low-power wake-up signal time-domain monitoring opportunities, as shown in Figure 6. In Figure 6, the two serving cells of the carrier aggregation are serving cell 1 and serving cell 2, and the cell numbers are 1 and 2 respectively. The low-power wake-up signal time-domain monitoring opportunities configured by the set of low-power wake-up signal resource configuration parameters correspond to the opportunity numbers 1, 2, 3, 4, 5, 6, etc. Then, the network device or terminal device can determine the low-power wake-up signal time-domain monitoring opportunities associated with each of the two serving cells according to the formula m mod n = 0.

The following is an example of how to implement the first low-power wake-up signal indicating whether to monitor or not monitor the PDCCH on N serving cells.

In some possible examples, the first low-power wake-up signal includes one bit, which is used to instruct the terminal device to monitor or not monitor the PDCCH on each of the N serving cells. If the value of the one bit is 0, it indicates that the terminal device does not monitor the PDCCH on each of the N serving cells; if the value of the one bit is 1, it indicates that the terminal device monitors the PDCCH on each of the N serving cells. Alternatively, if the value of the one bit is 0, it indicates that the terminal device monitors the PDCCH on each of the N serving cells; if the value of the one bit is 0, it indicates that the terminal device does not monitor the PDCCH on each of the N serving cells.

In this way, the low-power wake-up signal of this embodiment only needs to set one bit value to indicate whether to monitor or not monitor the PDCCH on the serving cell associated with the low-power wake-up signal, which can save the bit overhead of the low-power wake-up signal.

In some possible examples, the first low-power wake-up signal includes N bits; the N bits correspond one-to-one to N service cells, and each of the N bits is used to indicate whether the terminal device monitors or does not monitor the PDCCH on the service cell corresponding to each bit.

For example, taking the value of N as 3, the three service cells of the carrier aggregation are service cell 1, service cell 2, and service cell 3, and the first low-power wake-up signal contains 3 bits, which correspond one-to-one to the three service cells. Among them, the first bit corresponds to service cell 1, the second bit corresponds to service cell 2, and the third bit corresponds to service cell 3. If the first bit is 0, it indicates that the terminal device does not monitor PDCCH on service cell 1; if the first bit is 1, it indicates that the terminal device monitors PDCCH on service cell 1. Alternatively, if the first bit is 0, it indicates that the terminal device monitors PDCCH on service cell 1; if the first bit is 1, it indicates that the terminal device does not monitor PDCCH on service cell 1. For the second and third bits, the same logic can be understood and will not be repeated.

In some possible examples, the first low-power wake-up signal includes X bits, where X is a positive integer. Each of the X bits is associated with one or more service cells among the N service cells, and each bit is used to indicate whether the terminal device monitors or does not monitor the PDCCH on the service cell associated with each bit. If each bit is a first preset value, each bit is used to indicate that the terminal device monitors the PDCCH on the service cell associated with each bit; if each bit is a second preset value, each bit is used to indicate that the terminal device does not monitor the PDCCH on the service cell associated with each bit.

For example, taking the value of N as 4 and the value of X as 2, the N service cells are service cell 1, service cell 2, service cell 3, and service cell 4. Among them, the first bit of the X bits is associated with service cell 1 and service cell 2, and the second bit is associated with service cell 3 and service cell 4. If the first bit is 0, it indicates that the terminal device does not monitor the PDCCH in service cell 1 and service cell 2; if the first bit is 1, it indicates that the terminal device monitors the PDCCH in service cell 1 and service cell 2. Alternatively, if the first bit is 0, it indicates that the terminal device monitors the PDCCH in service cell 1 and service cell 2; if the first bit is 1, it indicates that the terminal device does not monitor the PDCCH in service cell 1 and service cell 2. For the second bit, the same logic applies and will not be repeated.

For another example, taking the value of N as 4 and the value of X as 3, the N service cells are service cell 1, service cell 2, service cell 3, and service cell 4. Among them, the first bit of the X bits is associated with service cell 1, the second bit is associated with service cell 2 and service cell 3, and the third bit is associated with service cell 4. If the first bit is 0, it indicates that the terminal device does not monitor the PDCCH on service cell 1; if the first bit is 1, it indicates that the terminal device monitors the PDCCH on service cell 1. Alternatively, if the first bit is 0, it indicates that the terminal device monitors the PDCCH on service cell 1; if the first bit is 1, it indicates that the terminal device does not monitor the PDCCH on service cell 1. For the second bit, the same logic applies and will not be repeated.

It should be noted that how to determine which serving cell or cells among the N serving cells each bit in the X bits is associated with, this embodiment may adopt the following method:

One is that the network device explicitly configures one or more serving cells associated with each bit in the X bits in the N serving cells to the terminal device through system information (such as SIB1 or other SIBs), RRC signaling, MAC signaling or DCI signaling.

For example, taking the example of the signaling carrying the first configuration information for network explicit configuration, based on Figure 3, after S320, the network device sends the first configuration information, which is used to configure one or more serving cells associated with each of the X bits in the N serving cells. Correspondingly, the terminal device receives the first configuration information. It can be seen that the network explicitly configures the one or more serving cells associated with each of the X bits through the first configuration information.

One is that the network device explicitly configures the bit associated with each of the N serving cells in the X bits to the terminal device through system information (such as SIB1 or other SIBs), RRC signaling, MAC signaling or DCI signaling.

For example, taking the example of explicit configuration performed by the signaling carrying the second configuration information, based on Figure 3, after S320, the network device sends the second configuration information, which is used to configure the bits associated with each of the N serving cells in the X bits. Correspondingly, the terminal device receives the second configuration information. It can be seen that the network explicitly configures the bits associated with each of the N serving cells in the X bits through the second configuration information.

In some possible examples, the first low-power wake-up signal includes Y bits, where the value of Y is a positive integer; each of the Y bits is associated with K service cells out of N service cells, where the value of K is a positive integer and the value of N is not less than the value of K, and each bit is used to instruct the terminal device to monitor or not monitor the PDCCH on the K service cells associated with each bit. If each bit is a first preset value, then each bit is used to instruct the terminal device to monitor the PDCCH on the K service cells; if each bit is a second preset value, then each bit is used to instruct the terminal device not to monitor the PDCCH on the K service cells.

For example, taking the value of N as 4, the value of Y as 2, and the value of K as 2, the N service cells are service cell 1, service cell 2, service cell 3, and service cell 4. Among them, the first bit of the Y bits is associated with service cell 1 and service cell 2, and the second bit is associated with service cell 3 and service cell 4. If the first bit is 0, it indicates that the terminal device does not monitor the PDCCH in service cell 1 and service cell 2; if the first bit is 1, it indicates that the terminal device monitors the PDCCH in service cell 1 and service cell 2. Alternatively, if the first bit is 0, it indicates that the terminal device monitors the PDCCH in service cell 1 and service cell 2; if the first bit is 1, it indicates that the terminal device does not monitor the PDCCH in service cell 1 and service cell 2. For the second bit, the same logic applies and will not be repeated.

It should be noted that how to determine whether each bit in the Y bits is associated with the K serving cells can be determined in the following manner in this embodiment:

One option is that this embodiment may specify that the value of K is determined by the values of N and Y. Thus, when a network device or terminal device learns the values of N and Y, it can determine the value of K based on the values of N and Y, thereby implicitly configuring the value of K. Furthermore, in some possible examples, the values of K, N, and Y satisfy the following formula: N/Y=K, i.e., the value of K is the value of N divided by the value of Y.

For example, if the value of N is 4 and the value of Y is 2, the four serving cells are serving cell 1, serving cell 2, serving cell 3, and serving cell 4, and the first low-power wake-up signal includes 2 bits. Among them, the first bit of the two bits is associated with serving cell 1 and serving cell 2, and the second bit is associated with serving cell 3 and serving cell 4.

One is that the network device explicitly configures the Y serving cells associated with each bit of the Y bits to the terminal device through system information (such as SIB1 or other SIBs), RRC signaling, MAC signaling or DCI signaling.

For example, taking the example of network explicit configuration carried by the signaling as an example, based on Figure 3, after S320, the network device sends the third configuration information, which is used to configure the K serving cells associated with each of the Y bits. Correspondingly, the terminal device receives the third configuration information. It can be seen that the network explicitly configures the Y serving cells associated with each of the Y bits through the third configuration information.

One is that the network device explicitly configures the bit associated with each of the K serving cells in the Y bits to the terminal device through system information (such as SIB1 or other SIBs), RRC signaling, MAC signaling or DCI signaling.

For example, taking the example of explicit configuration carried out by the signaling with the fourth configuration information, based on Figure 3, after S320, the network device sends the fourth configuration information, which is used to configure the bits associated with each of the K serving cells in the Y bits. Correspondingly, the terminal device receives the fourth configuration information. It can be seen that the network explicitly configures the bits associated with each of the K serving cells in the Y bits through the fourth configuration information.

The above mainly introduces the solution of the embodiment of the present application from the perspective of the method side. The following is an example of the functional unit of a communication device of this embodiment. It can be understood that in order to implement the above functions, the terminal device includes a hardware structure and/or software module corresponding to the execution of each function. It should be easy for those skilled in the art to realize that, in combination with the units and algorithm steps of each example described in the embodiment disclosed in this document, this embodiment can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this embodiment.

The embodiments of the present application can divide the terminal device into functional units according to the above method examples. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of a software program module. It should be noted that the division of units in the embodiments of the present application is schematic and is only a logical functional division. In actual implementation, other division methods can be used.

In the case of using integrated units, FIG7 is a block diagram of functional units of a communication device according to an embodiment of the present application, wherein the communication device 700 includes a receiving unit 701 .

Optionally, the receiving unit 701 may be a module unit for receiving and processing signals, information, etc., and there is no specific limitation on this.

Optionally, the communication device 700 may further include a sending unit, wherein the sending unit may be a module unit for sending and processing signals, information, etc., and is not specifically limited thereto.

Optionally, the communication device 700 may further include a storage unit for storing computer program codes or instructions executed by the communication device 700. The storage unit may be a memory.

Optionally, the communication device 700 may be a chip or a chip module.

Optionally, the receiving unit 701 may be integrated into a communication unit, wherein the communication unit may be a communication interface, a transceiver, a transceiver circuit, etc.

Optionally, the receiving unit 701 may be integrated into the processing unit.

It should be noted that the processing unit may be a processor or a controller, for example, a baseband processor, a baseband chip, a central processing unit (CPU), a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof. It may implement or execute the various exemplary logic blocks, modules, and circuits described in conjunction with the disclosure of this embodiment. The processing unit may also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of a DSP and a microprocessor, and the like.

In specific implementation, the receiving unit 701 is used to execute any step in the above method embodiment, and when executing an action such as sending, it can selectively call other units to complete the corresponding operation.

A receiving unit 701 is configured to receive first information, where the first information is used to configure a low-power wake-up signal resource;

The receiving unit 701 is also used to receive a first low-power wake-up signal on the low-power wake-up signal resource configured by the first information. The first low-power wake-up signal is used to instruct the terminal device to monitor or not monitor the PDCCH on N service cells among the M service cells of the carrier aggregation.
