[0002] With the further evolution of communication technologies, improving network energy efficiency has become a popular topic. Network devices (such as base stations) account for a relatively high proportion of network energy consumption. How to improve the energy efficiency of network devices has become an urgent problem to be solved. Summary of the Invention

[0003] One of the objectives of the embodiments of the present invention is to reduce the static energy consumption of network devices.

[0004] In a first aspect, the present invention provides a communication method, including: obtaining configuration information of a first wake-up signal in an anchor cell; sending the first wake-up signal, where the first wake-up signal indicates identification information of a first non-anchor cell or a first non-anchor cell group.

[0005] A terminal device obtains configuration information of a first wake-up signal in an anchor cell, sends first wake-up information based on the configuration information of the first wake-up signal, and indicates identification information of a first non-anchor cell or a first non-anchor cell group through the first wake-up signal. Thus, a network device can learn about the first non-anchor cell or the first non-anchor cell group indicated by the first terminal device. Furthermore, the network device can control the first non-anchor cell or the first non-anchor cell group, thereby reducing static energy consumption.

[0006] Optionally, the terminal device may further obtain system information of the first non-anchor cell or the first non-anchor cell group.

[0007] Optionally, the terminal device may obtain the system information of the first non-anchor cell or the first non-anchor cell group within a time window after sending the first wake-up signal.

[0008] That is to say, the terminal device may obtain the system information of the first non-anchor cell or the first non-anchor cell group within a time window after completing the sending of the first wake-up signal. Thus, the terminal device can avoid continuously listening to system information, thereby reducing power consumption.

[0009] Optionally, the terminal device may obtain the system information of the first non-anchor cell or the first non-anchor cell group sent by the anchor cell.

[0010] Optionally, the terminal device sends the first wake-up signal to the anchor cell. Thus, the anchor cell can determine the identification information of the first non-anchor cell or the first non-anchor cell group based on the first wake-up signal, and then send the system information of the first non-anchor cell or the first non-anchor cell group.

[0011] Optionally, the terminal device may also obtain indication information, which may be used to indicate that the system information is sent by the anchor cell.

[0012] Through the anchor cell, the system information of the first non-anchor cell or the first non-anchor cell group is sent. Thus, the first non-anchor cell or the first non-anchor cell group does not need to send the system information, so the signal transmission power consumption of the first non-anchor cell or the first non-anchor cell group can be saved, and further the static power consumption of the network device can be reduced.

[0013] Optionally, the terminal device may also obtain the system information sent by the first non-anchor cell or the first non-anchor cell group.

[0014] The terminal device may trigger the first non-anchor cell or the first non-anchor cell group to send the system information through the first wake-up signal of the anchor cell.

[0015] Optionally, the terminal device may send the first wake-up signal to the anchor cell, or send the first wake-up signal to the first non-anchor cell or the first non-anchor cell group.

[0016] Optionally, the terminal device may also obtain indication information, which is used to indicate that the system information is sent by the first non-anchor cell or the first non-anchor cell group.

[0017] Optionally, the first wake-up signal includes a first sequence, and the first sequence is associated with the identification information of the first non-anchor cell or the first non-anchor cell group; or, the first wake-up signal includes a sequence information code point, and the sequence information code point is associated with the identification information of the first non-anchor cell or the first non-anchor cell group; or, the time-frequency resource of the preamble of the random access channel associated with the first wake-up signal corresponds to the identification information of the first non-anchor cell or the first non-anchor cell group.

[0018] The terminal device may indicate the identification information of the first non-anchor cell or the first non-anchor cell group through the first sequence in the first wake-up signal. Or, the terminal device may indicate the identification information of the first non-anchor cell or the first non-anchor cell group through the sequence information code point. Or, the terminal device may determine the identification information of the first non-anchor cell or the first non-anchor cell group through the time-frequency resource of the preamble of the random access channel associated with the first wake-up signal. Thus, specific implementation manners for determining the identification information of the first non-anchor cell or the first non-anchor cell group are given.

[0019] In a second aspect, the present invention further provides a communication method, including: sending configuration information of the first wake-up signal; obtaining the first wake-up signal, where the first wake-up signal indicates the identification information of the first non-anchor cell or the first non-anchor cell.

[0020] Optionally, the anchor cell may also send the system information of the first non-anchor cell or the first non-anchor cell group.

[0021] Optionally, the system information of the first non-anchor cell or the first non-anchor cell group is sent after a preset duration from obtaining the first wake-up signal.

[0022] In a third aspect, the present invention further provides a communication device, including: an obtaining unit, configured to obtain configuration information of a first wake-up signal in an anchor cell; a sending unit, configured to send the first wake-up signal, where the first wake-up signal indicates identification information of a first non-anchor cell or a first non-anchor cell group.

[0031] In a communication system, to ensure the user experience of terminal devices, the network device is in a working state or a semi-sleep state and cannot be completely turned off or enter a deep sleep mode.

[0032] The power consumption of the network device mainly includes static power consumption and dynamic power consumption. The static power consumption of the network device mainly includes static reception power consumption and static transmission power consumption. Among them, the static reception power consumption mainly includes the network device receiving Message 1 (Msg1) on the configured random access resources, and the static transmission power consumption mainly includes Synchronization Signal Block (SSB), sending paging messages, sending System Information Block (SIB), etc. The dynamic power consumption of the network device mainly refers to the power consumption when the network device performs services and data, which changes with the changes in services and data volume.

[0033] It can be seen that reducing the static power consumption of the network device has become an important and effective way to improve the energy efficiency of the network device.

[0034] In the fifth-generation mobile communication (5G) system, there are more available spectrum resources. When the network load is low, some carriers (such as 4 GHz, 6 GHz, 26 GHz, etc.) or cells can be turned off and turned on as needed, thereby reducing the power consumption of the network device.

[0035] In the prior art, the above-mentioned carriers or cells that can be turned off still need to send measurement reference signals to support the access and mobility requirements of terminal devices. In some scenarios, the carriers or cells that can be turned off can also be referred to as non-anchor carriers or non-anchor cells, or as the second type of carriers or the second type of cells, or as secondary carriers or secondary cells. Correspondingly, the carriers or cells that are not turned off can also be referred to as anchor carriers or anchor cells, or as the first type of carriers or the first type of cells, or as primary carriers or primary cells.

[0036] The anchor cell can provide a larger coverage area, while the non-anchor cell can provide a smaller coverage area. Usually, the non-anchor cell can be deployed within the coverage area of the anchor cell, can provide high-speed data transmission services for terminal devices, and can be controlled and turned on as needed.

[0037] Refer to Figure 1, a schematic diagram of an existing network structure is given. Figure 1 Among them, within the coverage area of the anchor cell, it may include non-anchor cell 1, non-anchor cell 2, and non-anchor cell 3. It can be understood that Figure 1 it is only an exemplary illustration of the relationship between the anchor cell and the non-anchor cells.

[0038] In the embodiment of the present invention, the terminal device obtains the configuration information of the first wake-up signal in the anchor cell, sends the first wake-up information based on the configuration information of the first wake-up signal, and indicates the identification information of the first non-anchor cell or the first non-anchor cell group through the first wake-up signal. Thus, the network device can learn the first non-anchor cell or the first non-anchor cell group indicated by the first terminal device. The network device can configure the anchor cell to send the system information of the first non-anchor cell or the first non-anchor cell group, thereby reducing the static power consumption of the non-anchor cell and further reducing the static power consumption of the network device.

[0039] To make the above objects, features, and beneficial effects of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0040] The terminal device described in the embodiments of the present application is a device with wireless communication capabilities, and can also be referred to as a terminal, mobile station (MS), mobile terminal (MT), access terminal device, in-vehicle terminal device, industrial control terminal device, user equipment (UE), UE unit, UE station, mobile station, remote station, remote terminal device, mobile device, wireless communication device, UE agent, or UE device, etc. The UE can be fixed or mobile. It should be noted that the UE can support at least one wireless communication technology, such as LTE, NR, etc. Exemplarily, the UE can be a mobile phone, tablet (pad), desktop computer, laptop computer, all-in-one computer, in-vehicle terminal, virtual reality (VR) UE, augmented reality (AR) UE, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device, or other processing devices connected to a wireless modem, wearable device, UE in a future mobile communication network, or UE in a future evolved public land mobile network (PLMN), etc. In some embodiments of the present application, the UE can also be a device with transceiver capabilities, such as a chip system. Among them, the chip system can include a chip and can also include other discrete devices.

[0041] In the embodiments of the present application, a network device is a device that provides wireless communication functions for terminal devices, and can also be referred to as a radio access network (RAN) device, or an access network element, an access network device, etc. Among them, the network device can support at least one wireless communication technology, such as LTE, NR, etc. Exemplarily, the network device includes, but is not limited to: the next-generation base station (generation nodeB, gNB) in 5G, evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved node B, or home node B, HNB), baseband unit (BBU), transmitting and receiving point (TRP), transmitting point (TP), mobile switching center, etc. The network device can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in the cloud radio access network (CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a terminal device, a wearable device, and a network device in future mobile communications or a network device in a future evolved PLMN, etc. In some embodiments, the network device can also be a device with the function of providing wireless communication for terminal devices, such as a chip system. Exemplarily, the chip system can include a chip and can also include other discrete devices.

[0042] In some embodiments, the network device can also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks, etc.

[0043] Embodiments of the present invention provide a communication method, as follows Figure 2 , which will be described in detail through specific steps below.

[0044] In an embodiment of the present invention, the communication method provided in the following steps 201 to 202 may be executed by a chip with data processing capabilities (such as a baseband chip) in a terminal device, or by a chip module with data processing capabilities in the terminal device, or by the terminal device. In the following embodiments, the terminal device is taken as an example for illustration.

[0045] Step 201: Obtain the configuration information of the first wake-up signal in the anchor cell.

[0046] In a specific implementation, the terminal device may camp within the coverage area of the anchor cell. The coverage area of an anchor cell may include one or more non-anchor cells. For example Figure 1 As shown, there are 3 non-anchor cells within the coverage area of an anchor cell.

[0047] The terminal device may also camp in the non-anchor cell at the same time. Taking the example in Figure 1 the terminal device may also camp in non-anchor cell 1, and non-anchor cell 1 provides high-speed data services for the terminal device.

[0048] The anchor cell may send the configuration information of the first wake-up signal to the terminal device within its coverage area. The configuration information of the first wake-up signal may include the time-domain resources, frequency-domain resources, etc. corresponding to the first wake-up signal, as well as the identification information of all or part of the non-anchor cells in the anchor cell, and the identification information of all or part of the non-anchor cell groups in the anchor cell. A non-anchor cell group may include one or more non-anchor cells.

[0049] It can be understood that the specific content included in the configuration information of the first wake-up signal may refer to the description in the existing protocol.

[0050] The terminal device may obtain the configuration information of the first wake-up signal sent by the anchor cell, and determine some or all of the non-anchor cells or non-anchor cell groups within the coverage area of the anchor cell. The terminal device may determine the non-anchor cells or non-anchor cell groups that it may potentially access. In the following embodiments, for ease of description, the non-anchor cells that the terminal device may potentially access are simply referred to as the first non-anchor cells, and the non-anchor cell groups that the terminal device may access are simply referred to as the first non-anchor cell groups.

[0051] It can be seen that the first non-anchor cells or the first non-anchor cell groups can be determined based on the non-anchor cells or non-anchor cell groups indicated in the configuration information of the first wake-up signal.

[0052] For example, the anchor cell sends the configuration information of the first wake-up signal to the terminal device, and the configuration information of the first wake-up signal indicates that the non-anchor cells within the coverage area of the anchor cell include non-anchor cell 1 to non-anchor cell 3.

[0053] Step 202: Send a first wake-up signal, where the first wake-up signal indicates the identification information of a first non-anchor cell or a first non-anchor cell group.

[0054] In a specific implementation, when the terminal device determines that the trigger condition for sending the wake-up signal is met, it may send the first wake-up signal based on the configuration information of the first wake-up signal. Through the first wake-up signal, the identification information of the first non-anchor cell or the first non-anchor cell group that the terminal device may hand over to can be indicated. The trigger condition for sending the wake-up signal may be that the signal quality of the anchor cell is lower than a threshold and / or the signal quality of the non-anchor cell is higher than a threshold.

[0055] That is to say, when the terminal device detects that the signal quality of the anchor cell is lower than a threshold and / or the signal quality of a certain non-anchor cell is higher than a threshold, it can be determined that the trigger condition is met.

[0056] Specifically, the terminal device may send the first wake-up signal to the anchor cell. Alternatively, the terminal device may send the first wake-up signal to the first non-anchor cell or the first non-anchor cell group.

[0057] In an embodiment of the present invention, the anchor cell may send indication information to the terminal device to indicate whether the system information of the first non-anchor cell or the first non-anchor cell group is sent by the anchor cell or by the non-anchor cell through the indication information.

[0058] That is to say, in some embodiments, the system information of the first non-anchor cell or the first non-anchor cell group may be sent by the anchor cell. In other embodiments, the system information of the first non-anchor cell may be sent by the first non-anchor cell, and the system information of the first non-anchor cell group may be sent by the first non-anchor cell group.

[0059] In a specific implementation, the anchor cell may send indication information to the terminal device through a high-layer signaling. For example, the anchor cell may send indication information to the terminal device through a Radio Resource Control (RRC) message, a broadcast message, etc.

[0060] In an embodiment of the present invention, the indication information may be carried by the configuration information of the first wake-up signal. Thus, in the configuration information of the first wake-up signal, in addition to the time-domain resources, frequency-domain resources, identification information of all or part of the non-anchor cells in the anchor cell, identification information of all or part of the non-anchor cell groups in the anchor cell, etc. related to the first wake-up signal, the indication information may also be included.

[0061] Alternatively, the indication information and the configuration information of the first wake-up signal may also be different signaling. The network device may separately send the indication information and the configuration information of the first wake-up signal to the terminal device.

[0062] In a specific implementation, the terminal device may send a first wake-up signal to the anchor cell. Thus, the anchor cell may obtain the identification information of the first non-anchor cell or the first non-anchor cell group based on the first wake-up signal. After receiving the first wake-up signal, the anchor cell may send the system information of the first non-anchor cell or the first non-anchor cell group.

[0063] That is to say, in the embodiment of the present invention, the system information that was originally to be sent by the first non-anchor cell or the first non-anchor cell group is sent by the anchor cell.

[0064] It can be seen that the terminal device can inform the anchor cell of the identification information of the first non-anchor cell or the first non-anchor cell group through the first wake-up signal. The anchor cell sends the system information of the first non-anchor cell or the first non-anchor cell group to the terminal device, so that it is not necessary for the first non-anchor cell or the first non-anchor cell group to send the system information to the terminal device, thereby saving the signal transmission power consumption of the first non-anchor cell or the first non-anchor cell group.

[0065] In a specific implementation, the anchor cell may send the system information of the first non-anchor cell or the first non-anchor cell group within a time window after receiving the first wake-up signal. Correspondingly, the terminal device may receive the system information of the first non-anchor cell or the first non-anchor cell group within a time window after sending the first wake-up signal.

[0066] In some embodiments, the time domain position of the time window may be pre-configured, or configured and sent to the terminal device by the anchor cell. The time domain position of the time window may be determined by the time domain start position of the time window and the time length of the time window. Alternatively, the time domain position of the time window may be determined by the time domain end position of the time window and the time length of the time window.

[0067] In other embodiments, the time window may be implemented by means of a timer. By configuring the start time and the timing duration of the timer, the specific time domain position of the time window can be determined.

[0068] In a specific implementation, after receiving the first wake-up signal, the anchor cell may instruct the first non-anchor cell or the first non-anchor cell group to send system information. Alternatively, the terminal device may send a first wake-up signal to the first non-anchor cell, and after receiving the first wake-up signal, the first non-anchor cell sends the system information to the terminal device; the terminal device may send a first wake-up signal to the first non-anchor cell group, and after receiving the first wake-up signal, the first non-anchor cell group sends the system information to the terminal device.

[0069] In a specific implementation, the first non-anchor cell may send the system information of the first non-anchor cell within a time window after the terminal device sends the first wake-up signal. Correspondingly, the terminal device may receive the system information of the first non-anchor cell within a time window after sending the first wake-up signal.

[0070] Alternatively, the first non-anchor cell group may send the system information of the first non-anchor cell group within a time window after the terminal device sends the first wake-up signal. Correspondingly, the terminal device may receive the system information of the first non-anchor cell group within a time window after sending the first wake-up signal.

[0071] In a specific implementation, the time domain position of the above time window may be pre-configured, or configured and sent to the terminal device by the anchor cell. The time domain position of the time window may be determined by the time domain start position of the time window and the time length of the time window. Alternatively, the time domain position of the time window may be determined by the time domain end position of the time window and the time length of the time window.

[0072] In some other embodiments, the time window may be implemented by means of a timer. By configuring the start time of the timer and the timing duration, the specific time domain position of the time window can be determined.

[0073] It can be understood that the determination method of the time window may not be limited to the above examples.

[0074] In the embodiments of the present invention, the first wake-up signal may be a newly designed wake-up signal or may reuse the wake-up signal in the prior art.

[0075] In a specific implementation, the first wake-up signal may include a first sequence, and the length of the first sequence may be X bits. The specific value of X may be set according to the actual application scenario.

[0076] For example, if the number of non-anchor cells existing within the coverage area of the anchor cell is relatively large, the value of X may be relatively large; if the number of non-anchor cells existing within the coverage area of the anchor cell is relatively small, the value of X may be relatively small.

[0077] It can be understood that the value of X may also be pre-configured or system-predefined and may have nothing to do with the number of non-anchor cells in the anchor cell.

[0078] The network device may pre-configure the mapping relationship between the first sequence and the identification information of the first non-anchor cell or the first non-anchor cell group, and the network device may also pre-send the mapping relationship to the terminal device. After the terminal device determines the first non-anchor cell or the first non-anchor cell group, it may determine the value of the first sequence in the first wake-up signal, and then generate the corresponding first wake-up signal.

[0079] For example, the network device pre-configures the length X of the first sequence to be 3. The following mapping relationship is pre-configured: when the value of the first sequence is 001, the identification information of the non-anchor cell is 1; when the value of the first sequence is 010, the identification information of the non-anchor cell is 2; when the value of the first sequence is 011, the identification information of the non-anchor cell is 3. If the terminal device determines that the first non-anchor cell is non-anchor cell 1, then in the generated first wake-up signal, the value of the first sequence is 001.

[0080] In a specific implementation, the first wake-up signal may include sequence information code points, and the sequence information code points may be associated with the identification information of the first non-anchor cell or the first non-anchor cell group. The relationship between the above sequence information code points and the identification information of the first non-anchor cell or the first non-anchor cell group may be known to both the network device and the terminal device.

[0081] Specifically, the relationship between the above sequence information code points and the identification information of the first non-anchor cell or the first non-anchor cell group may be configured by the network device and sent to the terminal device.

[0082] In some embodiments, when the identification information of the non-anchor cell or the non-anchor cell group is less than a certain sequence information code point, it may be determined that the sequence information code point is invalid; other sequence information code points less than the identification information of the non-anchor cell or the non-anchor cell group correspond to the identification information of different non-anchor cells or non-anchor cell groups.

[0083] For example, the sequence information code points include 00, 01, 10, 11, and the number of non-anchor cells is 3. Then the sequence information code point 11 is invalid, 00 corresponds to non-anchor cell 1, 01 corresponds to non-anchor cell 2, and 10 corresponds to non-anchor cell 3. If the terminal device determines that the first non-anchor cell is non-anchor cell 2, then in the first wake-up information, the sequence information code point 01 is carried.

[0084] When the identification information of the non-anchor cell or the non-anchor cell group is greater than the sequence information code point, then at least some sequence information code points may repeatedly correspond to the identification information of different non-anchor cells or non-anchor cell groups.

[0085] For example, the sequence information code points include 00, 01, 10, 11, and the number of non-anchor cells is 8. Then 00 corresponds to non-anchor cell 1 and non-anchor cell 5, 01 corresponds to non-anchor cell 2 and non-anchor cell 6, 10 corresponds to non-anchor cell 3 and non-anchor cell 7, and 11 corresponds to non-anchor cell 4 and non-anchor cell 8. If the terminal device determines that the first non-anchor cell is non-anchor cell 4, then in the first wake-up information, the sequence information code point 11 is carried.

[0086] In a specific implementation, the identification information of the first non-anchor cell or the first non-anchor cell group may also be determined by the time-frequency resources of the preamble of the random access channel associated with the first wake-up signal. Alternatively, the identification information of different first non-anchor cells or first non-anchor cell groups may also be corresponding to different preamble indexes.

[0087] It can be understood that there may also be other implementation manners that can implement determining the identification information of the first non-anchor cell or the first non-anchor cell group through the first wake-up signal, which are not listed one by one here.

[0088] Referring to Figure 3 , another communication method in the embodiments of the present invention is given.
