Description

A communication method and related equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 6, 2024, with application number 202410171529.3 and invention name “A communication method and related equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method and related equipment. Background Art

[0003] Wireless communication can be the transmission of information between two or more communication nodes without using conductors or cables, or over the air. For example, communication nodes include network devices and terminal devices. Generally, terminal devices can access network devices and receive scheduling and instruction information from them to achieve wireless communication.

[0004] Currently, in the discontinuous reception (DRX) mechanism, terminals need to monitor the Physical Downlink Control Channel (PDCCH), which means the main receiver needs to be turned on. If a low-power receiver can be introduced to receive a low-power wake-up signal, it can replace PDCCH monitoring when there is no business, which can further save power consumption. Currently, there is a discussion direction: the terminal can be configured with WUS in the connected state, but the WUS monitoring timing is unrelated to any medium access control (MAC) process. It only wakes up the terminal's main receiver. After waking up, it runs the MAC protocol completely according to existing technologies, including DRX, DCP, etc.

[0005] However, in the above solution, if the terminal turns off the main receiver, it needs to keep the auxiliary receiver turned on to receive WUS, resulting in high energy consumption of the terminal. Summary of the Invention

[0006] An embodiment of the present application provides a communication method and related equipment. By sending first configuration information, the network device can enable the terminal device to periodically use the first receiver to receive WUS according to the WUS period indicated by the first configuration information, thereby reducing the energy consumption problem caused by keeping the first receiver open to receive WUS.

[0007] In a first aspect, the present application provides a communication method, which is executed by a network device, or the method is executed by some components in the network device (such as a processor, a chip or a chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the network device functions. In the first aspect and its possible implementation, the method is described as being executed by a network device. In this method, the network device determines first configuration information, and the first configuration information is used to indicate the wake-up signal WUS period of the terminal device.

[0008] Based on the above solution, the network device can send the first configuration information to enable the terminal device to periodically use the first receiver to receive WUS according to the WUS period indicated by the first configuration information, thereby reducing the energy consumption problem caused by keeping the first receiver open to receive WUS.

[0011] Optionally, in a possible implementation manner of the first aspect, the above-mentioned cell paging cycle is an integer multiple of the WUS cycle, or the WUS cycle is an integer multiple of the cell paging cycle.

[0012] In this possible implementation, by setting the WUS period to an integer multiple of the cell paging period, the cell paging monitoring can be overlapped with a certain WUS monitoring in time, thereby reducing the activation of an extra second receiver.

[0013] Optionally, in a possible implementation manner of the first aspect, the first configuration information is further used to instruct the terminal device to use a smaller cycle between the WUS cycle and the cell paging cycle to receive the WUS.

[0014] In this possible implementation, the smaller of the WUS period and the cell paging period is used to receive the WUS, thereby ensuring that the WUS will not be missed.

[0016] Based on the above solution, the terminal device can specify the WUS period through the first configuration information, so that the first receiver can be used periodically to receive the WUS, thereby reducing the energy consumption problem caused by always opening the first receiver to receive the WUS.

[0017] Optionally, in a possible implementation of the second aspect, the above steps also include: receiving second configuration information, the second configuration information is used to indicate the cell paging cycle of the terminal device, the cell paging cycle is used for the terminal device to periodically use the second receiver to receive paging; receiving paging based on the cell paging cycle; receiving WUS based on the WUS cycle, including: receiving WUS based on the WUS cycle and the cell paging cycle.

[0018] In this possible implementation, the network device and the terminal device periodically send and receive paging messages in an agreed manner, thereby reducing the power consumption of the terminal device receiving paging messages (or monitoring power consumption) while meeting the downlink delay.

[0019] Optionally, in a possible implementation of the second aspect, the above-mentioned first configuration information is also used to instruct the terminal device to use the smaller period between the WUS cycle and the cell paging cycle to receive WUS; receiving WUS based on the WUS cycle and the cell paging cycle includes: using the smaller period between the WUS cycle and the cell paging cycle to receive WUS.

[0052] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0053] First, some of the terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0054] 1. Radio resource control (RRC) status

[0055] In 4G and 5G cellular communication systems, the network provides services to terminals in cells. After selecting a cell, a terminal device resides in that cell, ready to initiate uplink services and receive downlink services at any time. From the perspective of the radio access network, a terminal device in a cell has three different RRC states: RRC connected (RRC_Connected), RRC idle (RRC_IDLE), and RRC inactive (RRC_INACTIVE).

[0056] RRC connected state: The terminal device has established an RRC connection with the network, enabling data transmission. The RRC connected state can also be referred to as the connected state. In this document, "connected state" and "RRC connected state" are the same concept and can be referred to interchangeably.

[0057] For example, the terminal device responds to network paging or actively initiates random access, establishes an RRC connection with the network device, and transmits services. For the network device and the core network device, the terminal device is visible.

[0058] RRC Idle State: The terminal device has not established an RRC connection with the network, and the network equipment has not stored the context of the terminal device. If the terminal device needs to enter the RRC Connected State from the RRC Idle State, it needs to initiate the RRC connection establishment process. The RRC Idle State can also be simply referred to as the Idle State. In this article, "Idle State" and "RRC Idle State" are the same concept and can be referred to interchangeably.

[0059] For example, a terminal device resides in a cell and has no ongoing services. It is invisible to network devices and core network devices. The terminal device monitors system broadcasts and paging.

[0060] System broadcast: Ensures that the latest system information is saved at all times to monitor paging (triggering cell access for uplink services) and initiate random access (active access to the network for uplink services) as needed.

[0061] Paging: includes network downlink service triggering, system message changes, multicast service start indication, etc.

[0062] RRC inactive state: The terminal device has previously entered the RRC connected state, and then the base station released the RRC connection, but the base station saved the context of the terminal device. If the terminal device needs to enter the RRC connected state again from the RRC inactive state, it is necessary to initiate an RRC recovery process (or called an RRC connection recovery process). Compared with the RRC establishment process, the RRC recovery process has a shorter delay and lower signaling overhead. However, the base station needs to save the context of the terminal device, which will occupy the storage overhead of the base station. The RRC inactive state can also be referred to as the inactive state. In this article, "deactivated state", "deactivated state", "inactive state", "RRC inactive state" and "RRC deactivated state" are the same concept, and these names can be interchanged.

[0063] For example, if a terminal device is stationed in a cell with no ongoing services, the network device typically configures the terminal device to enter the connected state when releasing the connected state. This state is invisible to the network device, but the core network device still considers the terminal device to be in the connected state. The terminal device behaves similarly to the idle state, primarily listening for paging and system messages. The main difference is that paging is primarily Radio Access Network (RAN) paging sent by the network device.

[0064] 2. Discontinuous Reception (DRX)

[0065] 5G New Radio (NR) technology uses the DRX mechanism from Long Term Evolution (LTE), which was introduced primarily to save power. The DRX cycle consists of an "On Duration" portion and an "Opportunity for DRX" portion. During the "On Duration" period, the terminal monitors and receives the PDCCH. During the "Opportunity for DRX" period, the terminal may not monitor or receive the PDCCH to reduce power consumption. Monitoring and receiving the PDCCH refers to monitoring and receiving the DCI carried on the PDCCH.

[0066] 3. Paging

[0067] Paging is a process in which a network-side device periodically sends paging messages to terminals in an idle or inactive state to wake up the terminals in the idle or inactive state and return them to a connected state. In one possible design, the process includes: a network-side device (such as an access network device) can calculate the paging occasion (PO) corresponding to the terminal. The PO appears periodically, and the period in which the terminal's own PO appears is called a paging cycle. When the network-side device needs to page the terminal, a physical downlink control channel (PDCCH) carrying paging downlink control information (DCI) is sent to the terminal on the terminal's PO. The paging DCI can be used to indicate whether the paging DCI schedules a physical downlink shared channel (PDSCH) carrying a paging message.

[0068] 4. Configuration and pre-configuration

[0069] In this application, configuration and pre-configuration are used simultaneously. Configuration refers to the network device / server sending some parameter configuration information or parameter values ​​to the terminal through messages or signaling, so that the terminal can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration and can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, parameter information or parameter values ​​used by the base station / network device or terminal device as specified in the standard protocol, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0070] Furthermore, these values ​​and parameters can be changed or updated.

[0071] 5. In this application, "used for indication" can include direct indication and indirect indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0072] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, it can be implemented by direct indication, such as by indicating the information to be indicated itself or the index of the information to be indicated. It can also be implemented by indirectly indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated in the protocol), thereby reducing the indication overhead to a certain extent.

[0073] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of RRC signaling, medium access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes MAC CE; physical layer signaling, for example, includes downlink control information (DCI).

[0074] 6. In the embodiments of this application, "sending" and "receiving" refer to the direction of signal transmission. In this application, when entity A sends information to entity B, A may send it directly to B or indirectly to B through another entity. Similarly, when entity B receives information from entity A, entity B may directly receive the information sent by entity A or indirectly receive the information sent by entity A through another entity. Entities A and B herein may be RAN nodes or terminals, or modules within a RAN node or terminal. The sending and receiving of information may be information exchange between a RAN node and a terminal, for example, between a base station and a terminal; between two RAN nodes, for example, between a CU and a DU; or between different modules within a device, for example, between a terminal chip and other modules in the terminal, or between a base station chip and other modules within the base station. "Sending" may also be understood as the "output" of a chip interface, for example, the output from a baseband chip to a radio frequency chip, and "receiving" may also be understood as the "input" of a chip interface.

[0075] In addition, receiving a signal can also be called monitoring a signal.

[0076] 7. The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. Also, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects.

[0077] Currently, in the DRX mechanism, terminals need to monitor PDCCH, which means that the main receiver needs to be turned on. If a low-power receiver can be introduced to receive a low-power wake-up signal, it can replace PDCCH monitoring when there is no business, which can further save power consumption. There is currently a discussion direction: the terminal can be configured with WUS in the connected state, but the WUS monitoring timing has nothing to do with any MAC process. It only wakes up the terminal's main receiver. After waking up, it runs the MAC protocol completely according to existing technology, including DRX, DCP, etc. However, in the above solution, if the terminal turns off the main receiver, the auxiliary receiver needs to be turned on all the time to receive WUS, resulting in higher energy consumption of the terminal.

[0078] In order to solve the above technical problems, an embodiment of the present application provides a communication method and related equipment. By sending a first configuration information, the network device can enable the terminal device to periodically use the first receiver to receive WUS through the WUS period indicated by the first configuration information, thereby reducing the energy consumption problem caused by keeping the first receiver open to receive WUS.

[0079] Please refer to Figure 1A, which is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in Figure 1A, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The RAN 100 includes at least one RAN node (such as 110a and 110b in Figure 1A, collectively referred to as 110), and may also include at least one terminal (such as 120a-120j in Figure 1A, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1A). The terminal 120 is connected to the RAN node 110 via a wireless connection, and the RAN node 110 is connected to the core network 200 via a wireless or wired connection. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or they can be the same physical device that integrates the logical functions of the core network equipment and the logical functions of the RAN node. Terminals and RAN nodes may be connected to each other via wired or wireless means.

[0080] The RAN 100 may be an Evolved Universal Terrestrial Radio Access (E-UTRA) system, a NR system, or a future radio access system defined in 3GPP. The RAN 100 may also include two or more of the aforementioned different radio access systems. The RAN 100 may also be an open RAN (O-RAN).

[0081] A RAN node, also known as a radio access network device, RAN entity, or access node, is used to help terminals access a communication system wirelessly. In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, or a base station in a future mobile communication system. A RAN node can be a macro base station (such as 110a in Figure 1A), a micro base station, or an indoor station (such as 110b in Figure 1A), or a relay node or a donor node.

[0082] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing portions of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, as well as the service data adaptation protocol (SDAP) functions. The DU implements the base station's radio link control layer and medium access control (MAC) layer functions, as well as some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant 3GPP technical specifications. The RU can be used to implement the transmission and reception of radio frequency signals. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment, such as a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0083] In different systems, RAN nodes may have different names. For example, in an O-RAN system, the CU may be called an open CU (O-CU), the DU may be called an open DU (O-DU), and the RU may be called an open RU (O-RU). The RAN nodes in the embodiments of the present application may be implemented by software modules, hardware modules, or a combination of software modules and hardware modules. For example, the RAN node may be a server loaded with the corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form used by the RAN node.

[0084] In addition, a RAN node can also be referred to as a network device. A network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices may include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, etc. In systems using different radio access technologies, the names of network devices may be different, such as eNB or eNodeB (evolutionary NodeB) in Long Term Evolution (LTE). A network device may also be a wireless controller in a cloud radio access network (CRAN) scenario. A network device may also be a base station device in a future 5G network or a network device in a future evolved PLMN network. A network device may also be a wearable device or an in-vehicle device. A network device may also be a transmission and reception point (TRP). In addition, in a network structure, a network device may include a centralized unit (CU) node, a distributed unit (DU) node, or a RAN device including a CU node and a DU node. For ease of description, the following description uses a base station as an example of a RAN node.

[0085] A terminal is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.

[0086] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0087] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1A can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1A can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1A can be referred to as communication devices with terminal functionality.

[0088] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0089] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.

[0090] It can be understood that the RAN 100 described above includes at least one RAN node (such as 110 a and 110 b in FIG. 1A , collectively referred to as 110 ), and may also include at least one terminal (such as 120 a - 120 j in FIG. 1A , collectively referred to as 120 ).

[0091] In one possible implementation, the communication system shown in FIG1A may also be as shown in FIG1B , that is, including a RAN node 110 and multiple terminals (such as 120A and 120B in FIG1B ). In this case, a single RAN node can transmit data or control signaling to a single terminal or multiple terminals.

[0092] In another possible implementation, the communication system shown in FIG1A may also be shown in FIG1C , that is, include multiple RAN nodes (such as 110A, 110B, and 110C in FIG1C ) 110 and a terminal 120. In this case, multiple RAN nodes may also simultaneously transmit data or control signaling for a single terminal.

[0093] Please refer to Figure 2, which is a flow chart of a communication method provided in an embodiment of the present application. The method may include steps 201 to 204. Steps 201 to 204 can be performed by a communication device (network device and / or terminal device), or can be performed by some components in the communication device (such as a processor, chip or chip system, etc.), or can be implemented by a logic module or software that can realize all or part of the functions of the communication device. The following description is taken as an example of execution by a network device and a terminal device. The processing performed by a single execution subject in steps 201 to 204 can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, in the case where the communication device is a network device, the processing performed by the communication device can be divided into executions by at least one of the CU, DU and RU. Steps 201 to 204 are described in detail below.

[0094] Step 201: The network device determines first configuration information.

[0095] The network device determines first configuration information, where the first configuration information is used to indicate a WUS period of the terminal device, where the WUS period is used for the terminal device to periodically use the first receiver to receive WUS, and where the WUS is used to indicate whether to enable the second receiver to receive paging.

[0096] The terminal device in this application includes a first receiver and a second receiver, and the operating power of the first receiver is less than the operating power of the second receiver. The first receiver can also be called an auxiliary link receiver or a low power receiver (LR), and the second receiver can also be called a main link receiver (MR) or a high power receiver.

[0097] The above WUS period can also be understood as configuring a period for the LR to monitor the WUS, so as to reduce the power consumption caused by the LR always monitoring the WUS.

[0098] Since the existing paging cell cycle is mainly used for terminal devices in idle state, the latency usually does not meet the requirements of terminal devices in connected state. To this end, this application provides a new connected state WUS cycle to meet the LR monitoring rule. The WUS cycle can be a new monitoring cycle or another paging cycle independent of the existing paging cell cycle.

[0099] Step 202: The network device sends first configuration information to the terminal device.

[0100] After determining the first configuration information, the network device sends the first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information sent by the network device.

[0101] Step 201 and step 202 can also be understood as a process in which the network device configures a WUS period for the terminal device.

[0102] Step 203: The network device sends the second configuration information to the terminal device. This step is optional.

[0103] Optionally, the network device sends second configuration information to the terminal device. Correspondingly, the terminal device receives the second configuration information sent by the network device. The second configuration information is used to indicate a cell paging cycle for the terminal device, and the cell paging cycle is used for the terminal device to periodically use the second receiver to receive paging.

[0104] Correspondingly, the network device may also send paging to the terminal device based on the cell paging cycle.

[0105] Furthermore, the cell paging cycle is N times the WUS cycle, or the WUS cycle is N times the cell paging cycle, where N is an integer greater than or equal to 2. By setting the WUS cycle to an integer multiple of the cell paging cycle, the cell paging monitoring can be overlapped with a WUS monitoring in time, thereby reducing the need to activate an additional MR.

[0106] Exemplarily, FIG3 shows an example in which the cell paging cycle is twice the WUS cycle (ie, N=2).

[0107] Step 204: The network device and the terminal device transmit WUS based on the WUS period.

[0108] After the network device sends the first configuration information to the terminal device, the network device and the terminal device transmit WUS based on the WUS period. This can also be understood as the network device and the terminal device transmitting WUS based on the first configuration information.

[0109] Specifically, the network device sends the WUS based on the WUS period. Correspondingly, the terminal device receives the WUS based on the WUS period. That is, the terminal device receives the WUS according to the regularity of the WUS period.

[0110] Optionally, the first configuration information or the second configuration information is further used to instruct the terminal device to use the smaller cycle between the WUS cycle and the cell paging cycle to receive the WUS. Of course, the terminal device can also be instructed by additional information to use the smaller cycle between the WUS cycle and the cell paging cycle to receive the WUS. In this case, the network device and the terminal device transmit the WUS based on the WUS cycle and the cell paging cycle, or the network device and the terminal device transmit the WUS based on the WUS cycle, the cell paging cycle and the additional information. By using a smaller cycle to transmit the WUS, it can be ensured that the WUS or paging will not be missed.

[0111] In an embodiment of the present application, on the one hand, by sending the first configuration information, the network device can enable the terminal device to periodically use the first receiver to receive the WUS through the WUS period indicated by the first configuration information, thereby reducing the energy consumption problem caused by always turning on the first receiver to receive the WUS. On the other hand, by setting the WUS period to an integer multiple of the cell paging period, the cell paging monitoring can be overlapped in time with a certain WUS monitoring, thereby reducing the need to turn on an additional MR. On the other hand, using the smaller period between the WUS period and the cell paging period to receive the WUS can ensure that the WUS or paging will not be missed.
