Abstract
Description
Technical Field
[0001] The present application relates to the field of communications, and in particular to a communication method and related equipment. Background Art
[0002] Wireless communication can be a transmission communication between two or more communication nodes that is not transmitted through conductors or cables or is transmitted through air interfaces. For example, the communication nodes include network devices and terminal devices. Generally, the terminal device can access the network device and receive scheduling and instruction information from the network device to achieve wireless communication.
[0003] Among them, one technical feature of base station energy saving is cell discontinuous transmission (DTX) / discontinuous reception (DRX). The basic idea is that the base station only sends and receives certain signals within a periodic time window, that is, it does not receive or send these signals outside the above time window. One technical feature of terminal energy saving is the reception mechanism based on the wake-up signal (Wake-Up Signal, WUS). The basic idea is that the terminal periodically detects the wake-up signal. Once the wake-up signal triggers the terminal to start receiving, the terminal will receive certain signals within the next period of time corresponding to the wake-up signal, otherwise the terminal will not receive these signals.
[0004] At present, in the DRX mechanism, once the terminal starts monitoring PDCCH periodically, it must monitor for at least the onduration length. However, there may be a situation where the terminal has no service scheduling in the current DRX cycle, and the onduration monitoring is wasted. For this reason, before the onduration of each DRX cycle, a downlink control information with cyclic redundancy check scrambled by PS-radio network tempory identity (DCP) scrambled by powersaving radio network tempory identity (PS-RNTI) is introduced.
[0005] However, how to combine WUS with DCP is a technical problem that needs to be solved urgently. Summary of the invention
[0006] The embodiment of the present application provides a communication method, in which a network device indicates to a terminal device through first configuration information whether to use WUS to receive DCP, that is, whether to use WUS to wake up the monitoring of DCP. Thus, WUS and DCP can be compatible, and the power consumption of the terminal device can be reduced by using WUS to wake up DCP.
[0007] In a first aspect, the present application provides a communication method, which is performed by a network device, or the method is performed 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 performed by a network device. In the method, the network device determines first configuration information, and the first configuration information is used to indicate whether to use a wake-up signal WUS to receive an encrypted downlink control information DCP with a cyclic redundancy check; the network device sends the first configuration information; the network device sends the DCP based on the first configuration information.
[0008] Based on the above solution, the network device can configure the first configuration information for the terminal device, so that the terminal device can clearly know whether to receive WUS first and then receive DCP according to WUS, or directly receive DCP without receiving WUS. That is, the terminal device can clearly know the association between WUS and DCP according to the first configuration information, which can not only make WUS and DCP compatible to reduce the power consumption of the terminal device, but also reduce the false alarms of functions of other terminal devices.
[0009] Optionally, in a possible implementation of the first aspect, when the first configuration information is used to indicate the use of WUS to receive DCP, the first configuration information is specifically used to indicate the association relationship between the functions of WUS and DCP, and the functions include at least one of the following: a wake-up indication, a secondary cell sleep indication; the wake-up indication is used to indicate whether the terminal device wakes up in the next discontinuous reception DRX cycle, and the secondary cell sleep indication is used to indicate whether to activate the secondary cell.
[0010] In this possible implementation, the first configuration information is specifically used to indicate the association between WUS and specific functions of DCP, so that the terminal device can clearly know which function or functions of DCP are associated with WUS, thereby reducing false alarms of terminal devices that are not configured with corresponding DCP functions.
[0011] Optionally, in a possible implementation manner of the first aspect, the above steps also include: sending second configuration information, where the second configuration information is used to instruct the terminal device to enable at least one of the following functions: a wake-up indication and a secondary cell sleep indication.
[0012] In this possible implementation, the DCP function can be configured for the terminal device through the second configuration information. For example, different DCP functions can be configured for multiple terminal devices. This can not only improve the flexibility of scheduling each terminal device, but also reduce false alarms of terminal devices that are not configured with the DCP function in combination with the first configuration information.
[0013] Optionally, in a possible implementation manner of the first aspect, the above steps further include: sending WUS when the first configuration information indicates to use WUS to receive DCP.
[0014] In this possible implementation, when the first configuration information indicates the use of WUS to receive DCP, the terminal device is triggered to receive DCP by sending WUS, thereby effectively combining WUS and DCP to reduce the energy consumption of the terminal device.
[0015] The second aspect of the present application provides a communication method, which is executed by a terminal device, or the method is executed by some components in the terminal 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 terminal device functions. In the second aspect and its possible implementation, the method is described as being executed by a terminal device. In the method, the terminal device receives first configuration information, and the first configuration information is used to indicate whether to use a wake-up signal WUS to receive an encrypted downlink control information DCP with a cyclic redundancy check; the terminal device receives the DCP based on the first configuration information.
[0016] Based on the above solution, the terminal device can specify through the first configuration information whether to receive WUS first and then receive DCP according to WUS; or directly receive DCP without receiving WUS. That is, the terminal device can specify the association between WUS and DCP according to the first configuration information, which can not only make WUS and DCP compatible to reduce the power consumption of the terminal device, but also reduce the false alarms of functions of other terminal devices.
[0017] Optionally, in a possible implementation of the second aspect, when the first configuration information is used to indicate the use of WUS to receive DCP, the first configuration information is specifically used to indicate the association relationship between the functions of WUS and DCP, and the functions include at least one of the following: a wake-up indication, a secondary cell sleep indication; the wake-up indication is used to indicate whether the terminal device wakes up in the next discontinuous reception DRX cycle, and the secondary cell sleep indication is used to indicate whether to activate the secondary cell.
[0018] In this possible implementation, the first configuration information is specifically used to indicate the association between WUS and specific functions of DCP, so that the terminal device can clearly know which function or functions of DCP are associated with WUS, thereby reducing false alarms of terminal devices that are not configured with corresponding DCP functions.
[0019] Optionally, in a possible implementation manner of the second aspect, the above steps also include: receiving WUS when the first configuration information indicates to use WUS to receive DCP; receiving DCP based on the first configuration information includes: receiving DCP based on WUS.
[0020] In this possible implementation, when the first configuration information indicates to use WUS to receive DCP, WUS is received and DCP is received according to WUS, thereby effectively combining WUS and DCP to reduce energy consumption of the terminal device.
[0021] Optionally, in a possible implementation of the second aspect, the above steps also include: obtaining second configuration information of the DCP, the second configuration information is used to instruct the terminal device to turn on at least one of the following functions: wake-up indication, secondary cell sleep indication; receiving the DCP based on the first configuration information, including: receiving the DCP based on the first configuration information and the second configuration information.
[0022] In this possible implementation, the second configuration information can enable the terminal device to clearly know which DCP function or functions it is configured with, and then determine how to receive DCP in combination with the association between the WUS and the DCP function indicated by the first configuration information. This can not only reduce the energy consumption of the terminal device, but also reduce false alarms of terminal devices that are not configured with the DCP function.
[0023] Optionally, in a possible implementation of the second aspect, the above-mentioned step: receiving DCP based on the first configuration information and the second configuration information includes: receiving DCP based on WUS when the first configuration information is specifically used to indicate that WUS is associated with the wake-up indication, and the second configuration information is used to instruct the terminal device to turn on the wake-up indication.
[0024] In this possible implementation, when the first configuration information indicates that WUS is associated with the wake-up indication and the terminal device is configured with this function, the terminal device receives DCP based on WUS, which can not only effectively combine WUS and DCP, but also reduce the energy consumption of the terminal device.
[0025] Optionally, in a possible implementation of the second aspect, the above-mentioned step: receiving DCP based on the first configuration information and the second configuration information includes: receiving DCP based on WUS when the first configuration information is specifically used to indicate that WUS is associated with the secondary cell sleep indication, and the second configuration information is used to instruct the terminal device to turn on the secondary cell sleep indication.
[0026] In this possible implementation, when the first configuration information indicates that WUS is associated with the secondary cell sleep indication, and the terminal device is configured with this function, the terminal device receives DCP based on WUS, which can not only effectively combine WUS and DCP, but also reduce the energy consumption of the terminal device.
[0027] Optionally, in a possible implementation of the second aspect, the above-mentioned step: receiving DCP based on the first configuration information and the second configuration information includes: receiving DCP when the first configuration information is specifically used to indicate that the WUS is associated with the secondary cell sleep indication, and the second configuration information does not indicate that the terminal device turns on the secondary cell sleep indication.
[0028] In this possible implementation, when the first configuration information indicates that WUS is associated with the secondary cell sleep indication, but the terminal device is not configured with this function, the terminal device may not receive DCP through WUS, but may directly receive DCP, thereby improving the efficiency of receiving DCP.
[0029] Optionally, in a possible implementation of the second aspect, the above-mentioned step: receiving DCP based on the first configuration information and the second configuration information includes: receiving DCP when the first configuration information is specifically used to indicate that WUS is associated with the wake-up indication, and the second configuration information does not indicate that the terminal device turns on the wake-up indication.
[0030] In this possible implementation, when the first configuration information indicates that WUS is associated with the wake-up indication, but the terminal device is not configured with this function, the terminal device may not receive DCP through WUS, but may directly receive DCP, thereby improving the efficiency of receiving DCP.

[0063] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0064] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
[0065] 1. Radio resource control (RRC) status
[0066] In 4G and 5G cellular communication systems, the network provides services to terminals in cells. After the terminal device selects a cell, it stays in the cell and can initiate uplink services at any time and is ready to receive downlink services from the network at any time. From the perspective of the wireless access network, the terminal device has three different RRC states in a cell: RRC connected state (RRC_Connected), RRC idle state (RRC_IDLE), and RRC inactive state (RRC_INACTIVE).
[0067] RRC connection state: The terminal device has established an RRC connection with the network and can transmit data. The RRC connection state can also be referred to as the connection state. In this article, "connection state" and "RRC connection state" are the same concept and the two names can be interchanged.
[0068] 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.
[0069] RRC idle state: The terminal device has not established an RRC connection with the network, and the network device 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 referred to as the idle state. In this article, "idle state" and "RRC idle state" are the same concept and the two names can be interchanged.
[0070] For example, when a terminal device resides in a cell and has no ongoing services, the terminal device is invisible to network devices and core network devices. The terminal device monitors system broadcasts and paging.
[0071] System broadcast: ensure that the latest system information is always saved in order to monitor paging (triggering cell access for uplink services) and initiate random access (active access to the network for uplink services) as needed at any time
[0072] Paging: includes network downlink service triggering, or system message changes, multicast service start indication, etc.
[0073] 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 the RRC recovery process (or called the RRC connection recovery process). Compared with the RRC establishment process, the RRC recovery process has a shorter delay and less 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.
[0074] For example, when a terminal device resides in a cell and has no ongoing services, the network device usually configures the terminal device to enter the connected state when releasing the connected state. This is invisible to the network device, and the core network device still considers the terminal device to be in the connected state. The behavior of the terminal device is similar to that in the idle state, mainly monitoring paging and system messages. The main difference is that the paging is mainly the Radio Access Network (RAN) paging sent by the network device.
[0075] 2. Discontinuous Reception (DRX)
[0076] The 5G new radio (NR) technology uses the DRX mechanism in the long term evolution (LTE) technology. The DRX mechanism is mainly introduced to save power consumption. Among them, the DRX cycle includes the "On Duration" part and the "DRX opportunity (Opportunity for DRX)" part. During the "On Duration" time, the terminal monitors and receives the PDCCH. During the "Opportunity for DRX" time, the terminal may not monitor or receive the PDCCH to reduce power consumption. Among them, monitoring and receiving the PDCCH can be understood as monitoring and receiving the DCI carried on the PDCCH.
[0077] 3. DCP
[0078] In the DRX mechanism, once the terminal starts monitoring the PDCCH periodically, it must monitor for at least the onduration length. However, there may be a situation where the terminal has no service scheduling in the current DRX cycle, and the onduration monitoring is wasted. For this reason, before the onduration of each DRX cycle, a downlink control information with cyclic redundancy check scrambled by PS-radio network temporary identity (DCP) scrambled by power saving radio network temporary identity (PS-RNTI) is introduced. The signal form of DCP can be DCI. The time domain position of DCP can be: an offset position before the "On Duration" time of the DRX cycle.
[0079] In addition, DCP has two functions, one is wake-up indication, which is used to indicate that the terminal does not need to wake up in the next DRX cycle, and the other is SCell dormancy indication, which is used to indicate whether to activate the SCell.
[0080] Wake-up indication is information in DCIFormat 2_6. '0' in this bit is used to indicate that the terminal does not need to wake up in the next DRX cycle, and '1' is used to indicate that the terminal needs to wake up in the next DRX cycle;
[0081] SCell dormancy indication, i.e. secondary cell dormancy indication, has a length of 0 to 5 bits. In general, even if there is no data transmitted on the SCell (secondary cell), the terminal still needs to monitor the PDCCH in these activated SCells, so 3GPP Release 15 introduced the SCell activation / deactivation mechanism. Activate the SCell when there is data, and deactivate the SCell when there is no data. However, this will introduce a large delay, so in order to reduce the delay, 3GPP Release 16 introduced SCell dormancy, which is achieved by switching between dormant part of the bandwidth (band width part, BWP) (dormant BWP) and activated BWP (non-dormant BWP).
[0082] 4. Wake-up signal
[0083] In 5G technology, terminals need to further save power consumption. For the current DRX mechanism, the terminal needs to monitor and receive PDCCH during the DRX activation time. However, in many cases, the UE cannot actually monitor the PDCCH used to schedule the UE during the DRX activation time, so the UE just wastes the power consumption of monitoring PDCCH. Therefore, it is proposed to introduce an indication signal (PDCCH-WUS), or a wake-up signal, which can indicate whether the UE needs to wake up or sleep during the subsequent DRX activation time based on the current DRX mechanism.
[0084] 5. Configuration and pre-configuration
[0085] In this application, configuration and pre-configuration are used at the same time. 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, or parameter information or parameter values used by the base station / network device or terminal device specified by 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.
[0086] Furthermore, these values and parameters can be changed or updated.
[0087] 6. In this application, "used for indication" may include being used for direct indication and being used for 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.
[0088] 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, specified by the protocol), thereby reducing the indication overhead to a certain extent.
[0089] 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 can be configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can include, for example, but not limited to, 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).
[0090] 7. "Send" and "receive" in the embodiments of the present application indicate the direction of signal transmission. In the present application, entity A sends information to entity B, which may be A directly sending to B, or A indirectly sending to B through other entities. Similarly, entity B receives information from entity A, which may be entity B directly receiving information sent by entity A, or entity B indirectly receiving information sent by entity A through other entities. Entities A and B here may be RAN nodes or terminals, or modules inside RAN nodes or terminals. The sending and receiving of information may be information interaction between a RAN node and a terminal, for example, information interaction between a base station and a terminal; the sending and receiving of information may also be information interaction between two RAN nodes, for example, information interaction between a CU and a DU; the sending and receiving of information may also be information interaction between different modules inside a device, for example, information interaction between a terminal chip and other modules of the terminal, or information interaction between a base station chip and other modules in the base station. "Send" may also be understood as the "output" of a chip interface, for example, the output of a baseband chip to a radio frequency chip, and "receive" may also be understood as the "input" of a chip interface.
[0091] 8. 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 represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated with each other 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 items or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, 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.
[0092] From the above introduction, it can be seen that how to combine WUS and DCP is a technical problem that needs to be solved urgently.
[0093] In order to solve the above technical problems, the embodiment of the present application provides a communication method and related devices, wherein the network device indicates to the terminal device through the first configuration information whether to use WUS to receive DCP, that is, whether to use WUS to wake up the monitoring of DCP. Thus, the terminal device can clearly understand the association between WUS and DCP, which can reduce the power consumption of the terminal device.
[0094] Assume that WUS and DCP are used in conjunction, that is, WUS instructs the terminal whether to monitor DCP. However, DCP is shared by multiple terminal devices, and each terminal device supports different DCP functions, which leads to false alarm problems when WUS is combined with DCP. For example, terminal 1 is awakened because terminal 2 is awakened. For another example, terminal 1 does not support the Scell dormancy function at all, but is awakened because of related functions of other terminals. The false alarm in the first example is a common situation in various wake-up mechanisms and can only be solved by grouping. The false alarm situation in the second example is more special and more unfair to terminal 1. Wake up and Scell dormancy are two standard functions, and both the terminal and the network may only implement one of them.
[0095] In order to further solve the above-mentioned false alarm problem, the embodiment of the present application can also specifically indicate the association between WUS and DCP function through the first configuration information, so that the terminal device that supports a certain DCP function can clearly determine whether to trigger a certain DCP function according to WUS according to the first configuration information, so as to reduce false alarms of other terminal devices that do not support a certain DCP function, thereby improving the energy saving of the terminal device.
[0096] See also Figure 1A, is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. Figure 1A As shown, 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 Figure 1A 110a and 110b in the figure, collectively referred to as 110), and may also include at least one terminal (such as Figure 1A RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1A (not shown in the figure). The terminal 120 is connected to the RAN node 110 by wireless means, and the RAN node 110 is connected to the core network 200 by wireless or wired means. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be independent and different physical devices, or may be the same physical device that integrates the logical functions of the core network device and the logical functions of the RAN node. Terminals and terminals and RAN nodes and RAN nodes may be connected to each other by wired or wireless means.
[0097] RAN 100 may be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, or a future radio access system defined in 3GPP. RAN 100 may also include two or more of the above different radio access systems. RAN 100 may also be an open RAN (O-RAN).
[0098] RAN node, also known as radio access network equipment, RAN entity or access node, is used to help terminals access the communication system wirelessly. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in the fifth generation (5G) mobile communication system, a next generation NodeB in the sixth generation (6G) mobile communication system, or a base station in a future mobile communication system. RAN nodes can be macro base stations (such as Figure 1A 110a), or a micro base station or an indoor station (such as Figure 1A110b) in the figure, it can also be a relay node or a donor node.
[0099] In another application scenario, the cooperation of multiple RAN nodes can be used to help the terminal achieve wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU) or a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of 3GPP. RU can be used to implement the transceiver function of radio frequency signals. CU and DU can be two independent RAN nodes, or they can be integrated in the same RAN node, such as integrated in a baseband unit (BBU). RU can be included in a radio frequency device, 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.
[0100] In different systems, RAN nodes may have different names. For example, in an O-RAN system, CU may be called an open CU (open CU, O-CU), DU may be called an open DU (open DU, O-DU), and RU may be called an open RU (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 corresponding software modules. The embodiments of the present application do not limit the specific technology and specific device form adopted by the RAN node.
[0101] In addition, a RAN node may also be referred to as a network device, which is a device deployed in a wireless 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 wireless access technologies, the names of network devices may be different, such as eNB or eNodeB (evolutional NodeB) in Long Term Evolution (LTE). The network device may also be a wireless controller in a cloud radio access network (CRAN) scenario. The network device may also be a base station device in a future 5G network or a network device in a future evolved PLMN network. The network device may also be a wearable device or a vehicle-mounted device. The network device may also be a transmission and reception point (TRP). In addition, in a network structure, the 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, a base station is used as an example of a RAN node for description below.
[0102] A terminal is a device with wireless transceiver function, which can send signals to a base station or receive signals from a base station. A terminal can also be called a terminal device, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.
[0103] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.
[0104] The roles of the base station and the terminal can be relative, for example, Figure 1A The helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal 120j that accesses the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and terminals can be collectively referred to as communication devices. Figure 1A 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 1A 120a-120j in the figure can be called communication devices with terminal functions.
[0105] Base stations and terminals, base stations and base stations, and terminals and terminals can communicate through authorized spectrum, unauthorized spectrum, or both; they can communicate 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.
[0106] 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 including the base station function. The control subsystem including the base station function 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 a modem) in the terminal, or by a device including the terminal function.
[0107] It can be understood that the RAN 100 has been described above as including at least one RAN node (such as Figure 1A 110a and 110b in the figure, collectively referred to as 110), and may also include at least one terminal (such as Figure 1A 120a-120j in the figure are collectively referred to as 120).
[0108] In one possible implementation, Figure 1A The communication system shown can also be Figure 1B As shown, it includes a RAN node 110 and multiple terminals (such as Figure 1BIn this case, a single RAN node may transmit data or control signaling to a single terminal or multiple terminals.
[0109] In another possible implementation, Figure 1A The communication system shown can also be Figure 1C As shown, it includes multiple RAN nodes (such as Figure 1C 110A, 110B and 110C in FIG. 110 and a terminal 120. In this case, multiple RAN nodes may also transmit data or control signaling for a single terminal at the same time.
[0110] See also Figure 2 , 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 may be performed by a communication device (network device and / or terminal device), or may be performed by some components in the communication device (such as a processor, a chip or a chip system, etc.), or may be implemented by a logic module or software that can implement 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 may also be divided into executions by multiple execution subjects, and these execution subjects may 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 may be divided into executions by at least one of a CU, a DU and a RU. Steps 201 to 204 are described in detail below.
[0111] Step 201: The network device determines first configuration information.
[0112] The network device determines the first configuration information, and the first configuration information is used to indicate whether to use WUS to receive DCP. Or it can be understood that the first configuration information is used to indicate whether to use WUS to wake up DCP for monitoring. It can also be understood that the first configuration information is used to indicate the association between WUS and DCP. It can also be understood that the first configuration information is used to instruct the terminal device to determine the order of receiving WUS and receiving DCP. The terminal device uses WUS to receive DCP, which can be understood as the terminal device determines whether to monitor DCP based on the status indication of WUS. It can also be understood as whether to use WUS to turn on the second receiver with higher working power to monitor DCP.
[0113] The terminal device in the present application includes a first receiver and a second receiver, and the working power of the first receiver is less than the working power of the second receiver. The first receiver may also be referred to as an auxiliary link receiver or a low power receiver (LR), and the second receiver may also be referred to as a main link receiver (MR) or a high power receiver.
[0114] Exemplarily, the status of WUS can be indicated by one or more bits. For example, taking 1 bit as an example, when WUS is "1", it indicates that the terminal device needs to turn on MR monitoring DCP. When WUS is "0", it indicates that the terminal device does not need to turn on MR monitoring DCP. It can be understood that when WUS is "0", it can also indicate that the terminal device needs to turn on MR monitoring DCP. When WUS is "1", it indicates that the terminal device does not need to turn on MR monitoring DCP. The specifics are not limited here. For another example, taking 3 bits as an example, the first bit is used to indicate whether to wake up, the second bit is specifically used to indicate the relationship with a certain DCP function, and the third bit is used to indicate the relationship with another DCP function. When WUS is "110", it indicates that the terminal device needs to turn on the DCP of the MR monitoring wake-up indication function. When WUS is "101", it indicates that the terminal device needs to turn on the DCP of the MR monitoring secondary cell sleep indication function. When WUS is "111", it indicates that the terminal device needs to turn on the DCP of the MR monitoring wake-up indication function and the secondary cell sleep indication function. It is understandable that when WUS is "0", it means that the terminal device needs to turn on the MR monitoring DCP. When WUS is "1", it means that the terminal device does not need to turn on the MR monitoring DCP. When WUS is "001", it means that the terminal device needs to turn on the DCP of the MR monitoring wake-up indication function, and so on.
[0115] Optionally, when the first configuration information indicates the use of WUS to receive DCP, the first configuration information is specifically used to indicate the association between the functions of WUS and DCP. The functions of DCP can be explained in the aforementioned related terms, and the functions of DCP include at least one of the following: wake-up indication, secondary cell dormancy indication, etc. The wake-up indication is used to indicate that the terminal device does not need to be woken up in the next DRX cycle. The secondary cell dormancy indication is used to indicate whether to activate the secondary cell (SCell). This situation can also be understood as that the first configuration information indicates which function of the DCP requires the terminal device to monitor.
[0116] Step 202: The network device sends first configuration information to the terminal device.
[0117] 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.
[0118] In a possible implementation, the first configuration information indicates to use WUS to receive DCP, and the network device also sends WUS to the terminal device.
[0119] In another possible implementation, the first configuration information indicates not to use WUS to receive DCP, and the network device may not send WUS to the terminal device.
[0120] Step 203: The network device sends second configuration information to the terminal device. This step is optional.
[0121] Optionally, the network device determines the second configuration information and sends the 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 instruct the terminal device to enable at least one of the following functions: a wake-up indication and a secondary cell sleep indication.
[0122] This step 203 can also be understood as a process in which the network device configures the DCP function for the terminal device.
[0123] It should be noted that, if step 203 exists, step 203 may be before step 202, before step 201, or after step 202, and the specific arrangement is not limited here.
[0124] Step 204: The network device and the terminal device transmit the DCP based on the first configuration information.
[0125] After the network device sends the first configuration information to the terminal device, the network device and the terminal device may transmit the DCP based on the first configuration information. That is, the network device may send the DCP based on the first configuration information. The terminal device may receive the DCP based on the first configuration information.
[0126] In a possible implementation, the first configuration information indicates to use WUS to receive DCP, and the terminal device first receives the WUS sent by the network device, and then receives the DCP based on the WUS.
[0127] In another possible implementation, the first configuration information indicates not to use WUS to receive DCP, and the terminal device may not receive WUS but directly receive DCP.
[0128] It can be understood that if step 203 exists, then in this step, the terminal device receives the DCP based on the first configuration information, which specifically includes the terminal device receiving the DCP based on the first configuration information and the second configuration information.
[0129] Optionally, the terminal device decides whether to monitor the DCP according to its own functional configuration. For example, if the terminal device does not support or is not configured with the secondary cell sleep indication association related function, it will not monitor the DCP even if it receives the WUS. There are multiple situations in which the terminal device receives the DCP based on the first configuration information and the second configuration information, which are described below:
[0130] 1. When the first configuration information is specifically used to indicate that WUS is associated with the wake-up indication, and the second configuration information is used to indicate that the terminal device turns on the wake-up indication, the DCP is received based on WUS. Alternatively, it is understood that when the first configuration information indicates that WUS is associated with the wake-up indication, and the terminal device is configured with the wake-up indication function, the terminal device receives the DCP based on WUS.
[0131] 2. When the first configuration information is specifically used to indicate that the WUS is associated with the secondary cell sleep indication, and the second configuration information is used to instruct the terminal device to turn on the secondary cell sleep indication, the DCP is received based on the WUS. Alternatively, it is understood that when the first configuration information indicates that the WUS is associated with the secondary cell sleep indication, and the terminal device is configured with the secondary cell sleep indication function, the terminal device receives the DCP based on the WUS.
[0132] 3. When the first configuration information is specifically used to indicate that the WUS is associated with the secondary cell sleep indication, and the second configuration information does not indicate that the terminal device turns on the secondary cell sleep indication, the DCP is received. Alternatively, it can be understood that when the first configuration information indicates that the WUS is associated with the secondary cell sleep indication, but the terminal device is not configured with the secondary cell sleep indication function, the terminal device does not need to receive the WUS and directly receives the DCP.
[0133] 4. When the first configuration information is specifically used to indicate that WUS is associated with the wake-up indication, and the second configuration information does not indicate that the terminal device turns on the wake-up indication, receive DCP. Alternatively, it can be understood that when the first configuration information indicates that WUS is associated with the wake-up indication, but the terminal device is not configured with the wake-up indication function, the terminal device does not need to receive WUS and directly receives DCP.
[0134] It is understandable that the above-mentioned situations are just examples. In actual applications, there are other situations, which are not specifically limited here.
[0135] The communication method provided in the embodiment of the present application may include steps 201 to 204. Alternatively, the communication method may include steps 201, 202 and 204.
[0136] In an embodiment of the present application, on the one hand, the network device indicates to the terminal device through the first configuration information whether to use WUS to receive DCP, that is, whether to use WUS to wake up the monitoring of DCP. The terminal device can clarify whether to receive WUS first and then receive DCP according to WUS according to the first configuration information; or directly receive DCP without receiving WUS. The terminal device clarifies the association between WUS and DCP according to the first configuration information, and can be compatible with WUS and DCP to reduce the power consumption of the terminal device. On the other hand, the association relationship between the functions of WUS and DCP is indicated by the first configuration information, and the DCP function of the terminal device is configured by the second configuration information, so that the terminal device can clarify whether to receive WUS first and then determine whether to trigger the DCP function according to WUS according to the first configuration information and the second configuration information; or directly trigger the DCP function without receiving WUS. False alarms of terminal devices with other DCP functions can be reduced.
