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] With the continuous development of the information age and the popularization and application of network communications, green communications has become a hot topic. Green communications aims to reduce the power consumption of communication systems, reduce the generation of electronic waste, and improve the effective use of resources. Among them, how to reduce the power consumption of communication equipment has attracted widespread attention.

[0003] In the related communication method, the network device in the multicast / broadcast service scenario sends the same data to multiple terminal devices at the same time. The network device always opens the downlink to send data, which continuously consumes power and leads to high power consumption. Summary of the invention

[0004] The present application provides a communication method and related equipment, in which a network device configures a cell discontinuous mechanism for a broadcast service and / or a multicast service, and sends a first message or a second message indicating the configuration to a terminal device in a non-connected state, so that the terminal device is configured synchronously. For the network device, the cell discontinuous mechanism means that when transmitting data related to a broadcast service and / or a multicast service with a terminal device in a non-connected state, it does not need to be transmitted continuously, but is transmitted within a specific time period according to the definition of the cell discontinuous mechanism, thereby saving power consumption of the network device.

[0005] In a first aspect, the present application provides a communication method, which is applied to a network device, including:

[0006] The first information or the second information is sent to a terminal device in a non-connected state, and the non-connected state includes a deactivated state and an idle state. The terminal device in the deactivated state has not established a connection with the base station, and a connection is established between the base station and the core network for the terminal device. No connection is established between the terminal device in the idle state and the base station, and between the base station and the core network for the terminal device. Among them, the first information indicates that the network device configures the first cell (cell) discontinuous transmission mechanism (DTX) and / or the first cell discontinuous reception (DRX) mechanism of the multicast service. Multicast service is a point-to-multipoint communication service. In the multicast service scenario, the network device sends the same data to multiple terminal devices. The cell discontinuous mechanism of the multicast service includes the first cell discontinuous transmission mechanism and the first cell discontinuous reception mechanism. The first cell discontinuous transmission mechanism defines the activation period and the inactivation period of the network device in sending data. When in the activation period of data sending, the network device sends multicast service data. When in the inactivation period of data sending, the network device does not send multicast service data. The first cell discontinuous reception mechanism defines the activation period and inactivation period of the network device in receiving data. When in the activation period of data reception, the network device receives feedback information for the multicast service; when in the inactivation period of data reception, the network device does not receive feedback information for the multicast service. The second information indicates that the network device configures the second cell discontinuous transmission mechanism and / or the second cell discontinuous reception mechanism for the broadcast service. The broadcast service is a point-to-all-point communication service. In the broadcast service scenario, the network device sends the same data to all terminal devices connected to it. The cell discontinuous mechanism of the broadcast service includes the second cell discontinuous transmission mechanism and the second cell discontinuous reception mechanism, which are similar to the cell discontinuous mechanism of the multicast service mentioned above and will not be repeated here. The difference is that in the broadcast service scenario, the network device and the terminal device transmit data related to the broadcast service.

[0007] Based on the above description, it can be known that the present application has the following beneficial effects: the network device sends a cell discontinuous sending mechanism and / or cell discontinuous receiving mechanism of a multicast service and / or a broadcast service configured by the network device to a terminal device in a non-connected state, thereby realizing that in a multicast service and / or a broadcast service scenario, the network device and the terminal device in a connected state transmit data of related services based on the cell discontinuous mechanism. In other words, for the network device, configuring the cell discontinuous mechanism means that when the network device transmits related data to the terminal device in a non-connected state, it does not need to transmit continuously, but transmits within a specific time period according to the definition of the cell discontinuous mechanism, thereby saving power consumption of the network device.

[0008] In some optional implementations of the first aspect, when the first information indicates that the network device configures the first cell discontinuous transmission mechanism, the first multicast service data is sent to the terminal device within a first activation period defined by the first cell discontinuous transmission mechanism. That is, the moment when the network device sends the first multicast service data to the terminal device is included in the first activation period defined by the first cell discontinuous transmission mechanism.

[0009] In the present application, the network device does not continuously send the first multicast service data to the terminal device, but sends the first multicast service data to the terminal device during the first activation period defined by the discontinuous transmission mechanism of the first cell. In other words, for the network device, during the transmission phase of the relevant data of the multicast service, the network device transmits the data to the terminal device discontinuously, and the network device does not need to be in the data transmission state all the time, thereby reducing the power consumption of the network device.

[0010] In some optional implementations of the first aspect, when the second information indicates that the network device configures the second cell discontinuous transmission mechanism, the first broadcast service data is sent to the terminal device within a third activation period defined by the second cell discontinuous transmission mechanism. That is, the moment when the network device sends the first multicast service data to the terminal device is included in the first activation period defined by the second cell discontinuous transmission mechanism.

[0011] In the present application, the network device does not continuously send the first broadcast service data to the terminal device, but sends the first multicast service data to the terminal device during the third activation period defined by the second cell discontinuous transmission mechanism. That is to say, for the network device, during the transmission phase of the multicast service related data, the network device sends the data to the terminal device discontinuously, and the network device does not need to be in the data transmission state all the time, thereby reducing the power consumption of the network device.

[0012] In some optional implementations of the first aspect, the non-connected state includes an idle state. For a terminal device in an idle state, the network device may configure a cell discontinuous reception mechanism. In the case where the first information indicates that the network device configures a first cell discontinuous reception mechanism, first feedback information for the first multicast service data from the terminal device is received within a third activation period defined by the first cell discontinuous reception mechanism. That is, the moment when the terminal device sends the first feedback information to the network device is included in the third activation period defined by the first cell discontinuous reception.

[0013] In the present application, the network device does not continuously receive feedback information for the first multicast service data from the terminal device, but receives the feedback information sent by the terminal device during the third activation period defined by the discontinuous reception mechanism of the first cell. In other words, for the network device, during the reception phase of the relevant data of the multicast service, the network device receives the data discontinuously, and does not need to be in a data receiving state or prepare for data reception (such as turning on the relevant modules for data reception, etc.) at all times, which further reduces the power consumption of the network device.

[0014] In some optional implementations of the first aspect, the non-connected state includes an idle state. When the second information indicates that the network device configures the second cell discontinuous reception mechanism, the second feedback information for the first broadcast service data is received from the terminal device within a fourth activation period defined by the second cell discontinuous reception mechanism. That is, the moment when the terminal device sends the second feedback information to the network device is included in the fourth activation period defined by the second cell discontinuous reception.

[0015] In the present application, the network device does not continuously receive the second feedback information from the terminal device, but receives the second feedback information sent by the terminal device during the fourth activation period defined by the discontinuous reception mechanism of the second cell. In other words, for the network device, during the reception phase of the relevant data of the broadcast service, the network device receives the data discontinuously, and does not need to be in the data reception state or prepare for data reception (such as turning on the relevant modules for data reception, etc.) at all times, which further reduces the power consumption of the network device.

[0016] In a second aspect, the present application provides a communication method, which is applied to a terminal device in a non-connected state, including:

[0017] Receive the first information or the second information from the network device, the first information indicates that the network device configures the first cell discontinuous transmission mechanism and / or the first cell discontinuous reception mechanism of the multicast service, and the second information indicates that the network device configures the second cell discontinuous transmission mechanism and / or the second cell discontinuous reception mechanism of the broadcast service. The cell discontinuous mechanism of the multicast service includes the first cell discontinuous transmission mechanism and the first cell discontinuous reception mechanism. The first cell discontinuous transmission mechanism defines the activation period and the inactivation period of the network device in terms of sending data. When in the activation period of data sending, the network device sends the relevant data of the multicast service. When in the inactivation period of data sending, the network device does not send the relevant data of the multicast service. The first cell discontinuous reception mechanism defines the activation period and the inactivation period of the network device in terms of receiving data. When in the activation period of data receiving, the network device receives the relevant data of the multicast service; when in the inactivation period of data receiving, the network device does not receive the relevant data of the multicast service. For the terminal device, the data from the network device is received during the activation period of data sending; and the data is sent to the network device during the activation period of data receiving. Similarly, the second information indicates that the network device configures the second cell discontinuous transmission mechanism and / or the second cell discontinuous reception mechanism of the broadcast service. The cell discontinuous mechanism of the broadcast service includes the second cell discontinuous transmission mechanism and the second cell discontinuous reception mechanism, which are similar to the cell discontinuous mechanism of the multicast service mentioned above and will not be repeated here. The difference is that in the broadcast service scenario, the network device and the terminal device transmit the relevant data of the broadcast service.

[0018] Based on the above description, it can be known that the present application has the following beneficial effects: a terminal device in a non-connected state receives the first information or the second information from a network device, and the first information instructs the network device to configure the non-continuous cell mechanism of the multicast service, so that in a multicast service scenario, when the network device and the terminal device in a non-connected state transmit the relevant data of the multicast service, it is not necessary to continuously transmit, but according to the definition of the non-continuous cell mechanism of the multicast service, it is transmitted within a specific time period, thereby saving the power consumption of the network device. The second information instructs the network device to configure the non-continuous cell mechanism of the broadcast service, so that in a broadcast service scenario, when the network device and the terminal device in a non-connected state transmit the relevant data of the broadcast service, it is not necessary to continuously transmit, but according to the definition of the non-continuous cell mechanism of the broadcast service, it is transmitted within a specific time period, thereby saving the power consumption of the network device.

[0019] In some optional implementations of the second aspect, when the first information indicates that the network device configures the first cell discontinuous transmission mechanism, the first multicast service data from the network device is received during the first activation period defined by the first cell discontinuous transmission mechanism. That is, the moment when the network device sends the first multicast service data to the terminal device, or the moment when the terminal device receives the first multicast service data, is included in the first activation period defined by the first cell discontinuous transmission mechanism.

[0020] In the present application, the network device does not continuously send the first multicast service data to the terminal device, and accordingly, the terminal device does not continuously receive the first multicast service data, so that the receiving mechanism of the terminal device matches the sending mechanism of the network device. Then for the terminal device, the first multicast service data is received only during the first activation period defined by the first cell discontinuous transmission mechanism, which can also reduce the power consumption of the terminal device.

[0021] In some optional implementations of the second aspect, when the second information indicates that the network device configures the second cell discontinuous transmission mechanism, the first broadcast service data from the network device is received during the second activation period defined by the second cell discontinuous transmission mechanism. That is, the moment when the network device sends the first broadcast service data to the terminal device, or the moment when the terminal device receives the first broadcast service data, is included in the second activation period defined by the second cell discontinuous transmission mechanism.

[0022] In this application, the network device does not continuously send the first broadcast service data to the terminal device, and accordingly, the terminal device does not continuously receive the first broadcast service data, so that the receiving mechanism of the terminal device matches the sending mechanism of the network device. Then for the terminal device, the first broadcast service data is received only during the second activation period defined by the first cell discontinuous transmission mechanism, which can also reduce the power consumption of the terminal device.

[0023] In some optional implementations of the second aspect, when the first information indicates that the network device configures the first cell discontinuous reception mechanism, first feedback information for the first multicast service data is sent to the network device within a third activation period defined by the first cell discontinuous reception mechanism. That is, the moment when the terminal device sends the first feedback information to the network device is included in the third activation period defined by the first cell discontinuous reception mechanism.

[0024] In the present application, the network device does not continuously receive the first feedback information for the first multicast service data from the terminal device, and accordingly, the terminal device does not continuously send the first feedback information to the network device, so that the sending mechanism of the terminal device matches the receiving mechanism of the network device. Then for the terminal device, the first feedback information is sent only during the third activation period defined by the first cell discontinuous reception mechanism, which can also reduce the power consumption of the terminal device.

[0025] In some optional implementations of the second aspect, when the second information indicates that the network device configures the second cell discontinuous reception mechanism, the second feedback information for the first broadcast service data is sent to the network device within a fourth activation period defined by the second cell discontinuous reception mechanism. That is, the moment when the terminal device sends the second feedback information to the network device is included in the fourth activation period defined by the first cell discontinuous reception mechanism.

[0026] In the present application, the network device does not continuously receive the second feedback information from the terminal device, and accordingly, the terminal device does not continuously send the second feedback information to the network device, so that the sending mechanism of the terminal device matches the receiving mechanism of the network device. Then for the terminal device, the second feedback information is sent only during the fourth activation period defined by the second cell discontinuous reception mechanism, which can also reduce the power consumption of the terminal device.

[0027] In some optional implementations of the first aspect or the second aspect, the first information includes a first periodic mode of a first cell discontinuous transmission mechanism, and / or a third periodic mode of a first cell discontinuous reception mechanism. Alternatively, the first information includes a first index value, and the first index value is used to index a first connected cell discontinuous transmission mechanism that has been configured by the network device, and / or a configured first connected cell discontinuous reception mechanism.

[0028] In the present application, the first information can define the cell discontinuous mechanism separately, or reuse the cell discontinuous mechanism that has been configured by the network device based on the index value, which enriches the implementation method and application scenario of the technical solution of the present application and improves the flexibility of the technical solution of the present application. In the scheme where the first information is defined separately, the terminal device can directly obtain the cell discontinuous mechanism configured by the network device according to the first information, which is simple to operate. In the scheme where the first information includes the index value, the reuse of the configured cell discontinuous mechanism not only reduces the amount of data transmitted by the network device and the terminal device and saves bandwidth resources, but also improves the utilization rate of the configured cell discontinuous mechanism.

[0029] In some optional implementations of the first aspect or the second aspect, the second information includes a second periodic mode of the second cell discontinuous transmission mechanism, and / or a fourth periodic mode of the second cell discontinuous reception mechanism. Alternatively, the second information includes a second index value, and the second index value is used to index the second connected cell discontinuous transmission mechanism that the network device has configured, and / or the configured second connected cell discontinuous reception mechanism.

[0030] In the present application, the second information can define the cell discontinuous mechanism separately, or reuse the cell discontinuous mechanism that has been configured by the network device based on the index value, which enriches the implementation method and application scenario of the technical solution of the present application and improves the flexibility of the technical solution of the present application. In the scheme where the second information is defined separately, the terminal device can directly obtain the cell discontinuous mechanism configured by the network device according to the second information, which is simple to operate. In the scheme where the second information includes the index value, the reuse of the already configured cell discontinuous mechanism not only reduces the amount of data transmitted by the network device and the terminal device and saves bandwidth resources, but also improves the utilization rate of the already configured cell discontinuous mechanism.

[0031] In some optional implementations of the first aspect or the second aspect, the first information or the second information is included in a radio resource control (RRC) layer message, a medium access control (NAS) layer message, or a physical layer message.

[0032] In the present application, the first information can be carried in various types of messages, enriching the implementation method of the technical solution of the present application.

[0033] In some optional implementations of the first aspect or the second aspect, the first information is carried in a multicast broadcast control channel for a multicast service. The second information is carried in a multicast broadcast control channel (MBS control channel, MCCH) for a broadcast service.

[0034] In some optional implementations of the first aspect or the second aspect, the first information corresponds to one or more multicast services, and the second information corresponds to one or more broadcast services.

[0035] In the present application, each multicast / broadcast service can be configured separately, or multiple multicast / multi-broadcast services can share the same configuration, which enriches the implementation method of the technical solution of the present application. In addition, in the solution where multiple multicast / multi-broadcast services share the same configuration, the network device can synchronize the cell discontinuous mechanism configurations of multiple multicast services / broadcast services by sending a first message / second message to the terminal device, thereby reducing the amount of data transmission between the network device and the terminal device and saving network resources.

[0036] In a third aspect, an embodiment of the present application provides a network device, including:

[0037] A transceiver unit is used to send first information or second information to a terminal device in a non-connected state, the first information instructs the network device to configure a first cell discontinuous sending mechanism and / or a first cell discontinuous receiving mechanism for a multicast service, and the second information instructs the network device to configure a second cell discontinuous sending mechanism and / or a second cell discontinuous receiving mechanism for a broadcast service.

[0039] In some optional implementations of the third aspect, the transceiver unit is further used to send the first broadcast service data to the terminal device within the second activation period defined by the second cell discontinuous transmission mechanism when the second information indicates that the network device configures the second cell discontinuous transmission mechanism.

[0063] Embodiments of the present application provide a communication method and related devices for reducing the power consumption of network devices.

[0064] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0065] First, the proper nouns and related concepts that may be involved in the embodiments of the present application are explained.

[0066] 1. Multicast.

[0067] Multicast is a point-to-multipoint communication method, which means that a multicast source (one or more hosts) sends the same data to multiple hosts at the same time. The basic concept of multicast is "group". The multiple hosts mentioned above can be understood as a multicast group. A multicast group is a group of receivers that expect to receive a specific data stream. Each node in the multicast group can be called a multicast group member. It should be noted that a multicast group has no physical or geographical boundaries, and the hosts in the group can be located anywhere on the Internet or a private network.

[0068] 2. Broadcast.

[0069] In the broadcast transmission mechanism, all network hosts are allowed to use the same communication channel. In broadcast mode, one host transmits data packets to all other hosts. This method is called "all-to-all". Unlike multicast transmission, in multicast mode, there is no need for group management.

[0070] 3. Non-connected terminal.

[0071] A non-connected terminal refers to a terminal device that is in an inactive or idle state. When a terminal device is in an inactive state, there is no connection between the terminal device and the base station, but a communication connection is established between the base station and the core network for the terminal device. When data needs to be sent to the terminal device, the base station will send a paging message, and the terminal device will establish a connection with the base station after receiving it, and the inactive state will be converted to the connected state. Among them, the inactive state can also be called the deactivated state.

[0072] When the terminal device is in the idle state, no communication connection is established between the terminal device and the base station, and between the base station and the core network for the terminal device. When there is data to be sent to the terminal device, or the terminal device needs to send data, the terminal device can be converted from the idle state to the connected state.

[0073] See below. Figure 1 , Figure 1 This is a schematic diagram of the system architecture provided in the embodiment of the present application. It can be understood that: Figure 1 Shown is one possible, non-limiting system schematic.

[0074] like Figure 1 As shown, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes a RAN node 110, a terminal device 121, a terminal device 122 and a terminal device 123.

[0075] Exemplarily, the terminal device 121 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the core network logical function and the radio access network logical function, which is not specifically limited here.

[0076] RAN 100 may be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or a future-oriented evolution system (such as a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0077] The RAN node 110, also known as a network device, sometimes also referred to as an access network device, a RAN entity or an access node, etc., is a part of a communication system and is used to help terminals achieve wireless access.

[0078] In some possible implementations, the RAN node 110 may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The RAN node 110 may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a wireless controller in a CRAN scenario. It should be noted that the RAN node 110 in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node 110, which is not specifically limited here.

[0079] The terminal device 121 may also be referred to as a terminal, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal in the embodiments of the present application 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, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, 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, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal. For example, Figure 1 Three different types of terminal devices are shown, namely terminal device 121, terminal device 122 and terminal device 123. In addition, all or part of the functions of the terminal device in the present application can also be implemented by software functions running on hardware, and the terminal device in the present application can also be a logical node, logical module or software that can implement all or part of the functions of the terminal device, which is not limited here.

[0080] It should be noted that Figure 1 This is just an example of a communication system. In actual applications, the RAN 100 may also include a greater number of RAN nodes and a greater or lesser number of terminal devices. The types of the multiple RAN nodes may be the same, partially the same, or completely different, and are not specifically limited here. The RAN 100 may also include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1 ).

[0081] In the present application, "sending information to... (such as a terminal device)" can be understood as the destination of the information being the terminal device. It can include sending information to the terminal device directly or indirectly. "Receiving information from... (such as a terminal device)" can be understood as the source of the information being the terminal device, which can include receiving information from the terminal device directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly and will not be repeated here.

A network device sends first information or second information to a terminal device in a non-connected state, wherein the first information instructs the network device to configure a cell discontinuous mechanism for a multicast service, and the second information instructs the network device to configure a cell discontinuous mechanism for a broadcast service.

[0084] It should be noted that the communication method provided in the embodiment of the present application is applied to a terminal device in a non-connected state, and the non-connected terminal has been described above and will not be repeated here. The terminal devices mentioned below all refer to terminal devices in a connected state.

[0085] The cell discontinuous mechanism of the multicast service indicated by the first information includes a first cell discontinuous transmission mechanism and / or a first cell discontinuous reception mechanism. The cell discontinuous mechanism of the broadcast service indicated by the second information includes a second cell discontinuous transmission mechanism and / or a second cell discontinuous reception mechanism.

[0086] Combine the following Figure 3 , which explains the cell discontinuity mechanism. Figure 3 , Figure 3 A schematic diagram of a cell discontinuity mechanism provided in an embodiment of the present application.

[0087] exist Figure 3 In the illustrated embodiment, two cell non-continuous cycles are shown, T2 represents one of the cycles, and the cycle includes two intervals: T1 and the interval outside T1. T1 represents the activation period, and the part outside T1 represents the inactivation period. The activation period is also called the on duration time. When in the activation period, the network device and the terminal device perform data transmission.

[0088] In the embodiment of the present application, the first cell discontinuous transmission mechanism defines the activation period and the inactivation period for the network device to send data to the terminal device in the multicast service scenario. The network device sends multicast service data to the terminal device only when it is in the activation period of data transmission. That is to say, the terminal device receives multicast service data from the network device during this period. The first cell discontinuous reception mechanism defines the activation period and the inactivation period for the network device to receive data from the terminal device in the multicast service scenario. The network device receives feedback information for the multicast service from the terminal device only when it is in the activation period of data reception. That is to say, the terminal device sends feedback information for the multicast service to the network device during this period.

[0089] Similarly, the second cell discontinuous transmission mechanism defines the activation period and inactivation period for the network device to send data to the terminal device in the broadcast service scenario. The network device sends broadcast service data to the terminal device only when it is in the activation period of data transmission. That is to say, the terminal device receives broadcast service data from the network device during this period. The first cell discontinuous reception mechanism defines the activation period and inactivation period for the network device to receive data from the terminal device in the broadcast service scenario. The network device receives feedback information for the broadcast service from the terminal device only when it is in the activation period of data reception. That is to say, the terminal device sends feedback information for the broadcast service to the network device during this period.

[0090] In the embodiment of the present application, the first information and the second information may include various contents. The following takes the first information as an example to illustrate possible situations:

[0091] In some optional implementations, the first information may define a cell discontinuous mechanism separately. Specifically, the first information includes a first periodic mode of a cell discontinuous transmission mechanism, and / or a third periodic mode of a cell discontinuous reception mechanism. In the case where the first information defines a cell discontinuous mechanism separately, the terminal device performs corresponding configuration according to the first information to ensure transmission of multicast service data with the network device based on the definition of the first information.

[0092] The periodic mode may also be referred to as a periodic pattern, which includes parameters for defining a cell discontinuous mechanism, such as a period, an offset, an activation period duration, a non-activation period duration, and the like.

[0093] For example, assuming that the first cycle mode includes a cycle of 150ms, an offset of 5ms, and an activation period of 80ms, it means that the cell discontinuous transmission mechanism starts from the 5th ms, and a cycle length defined by the mechanism is 150ms. In a cycle, the first 80ms is the activation period, and the last 70ms is the inactive period.

[0094] In some optional implementations, the first information includes a first index value, and the first index value is used to index the connected cell discontinuous transmission mechanism that the network device has configured, and / or the connected cell discontinuous reception mechanism that has been configured. In this case, the terminal device transmits multicast service data with the network device according to the connected cell discontinuous transmission mechanism that the network device corresponding to the first index value has configured, and / or the connected cell discontinuous reception mechanism that has been configured.

[0095] Exemplarily, it is assumed that before the network device sends the first information to the terminal device, it has configured two sets of connection state cell discontinuity mechanisms, and the corresponding identification numbers are cell DTX-1 and cell DRX-2. And these two sets of connection state cell discontinuity mechanisms have been synchronized between the terminal device and the network device, that is, the network device has informed the terminal device of these two sets of connection state cell discontinuity mechanisms, and when the network device and the terminal device perform data transmission of related services, they are based on the definition of these two sets of connection state cell discontinuity mechanisms.

[0096] In this example, it is assumed that the first information sent by the network device to the terminal device includes the identification number cell DRX-2, that is, the first index value is cell DRX-2. This means that when the network device transmits data of a multicast service with the terminal device, it is based on the connected cell discontinuous reception mechanism corresponding to cell DRX-2.

[0097] It should be noted that since inactive terminals have no feedback mechanism in multicast / broadcast service scenarios, it is not necessary to configure the cell discontinuous reception mechanism for inactive terminal devices. In other words, the network device configures the cell discontinuous reception mechanism for multicast / broadcast services only when the terminal device is in an idle state.

[0098] Exemplarily, it is assumed that before the network device sends the first information to the terminal device, two sets of cell discontinuous transmission mechanisms are synchronized between the terminal device and the network device, and the identification numbers are cell DTX-1 and cell DRX-1 respectively. If the index value carried in the first information sent by the network device to the terminal device is cell DTX-2, the terminal device has not received the relevant information of the cell discontinuous transmission mechanism corresponding to cell DTX-2 before. The terminal device sends a request to the network device, and the request carries the index value cell DTX-2 to obtain the relevant information of the cell discontinuous transmission mechanism corresponding to the index value. In other words, the network device responds to the request and sends the relevant information of the cell discontinuous transmission mechanism corresponding to cell DTX-2 to the terminal device to achieve synchronization of the cell discontinuous transmission mechanism between the terminal device and the network device. Afterwards, when the network device and the terminal device perform data transmission of multicast services, they are based on the connected cell discontinuous transmission mechanism corresponding to cell DTX-2.

[0099] It should be noted that the aforementioned identification number is only a possible example. In actual applications, other identification numbers may be used as index values ​​as long as they can uniquely identify a cell discontinuous mechanism. No specific limitation is made here.

[0100] It is understandable that the second information is similar to the first information and also has multiple possibilities. Optionally, the second information includes a second periodic mode of the second cell discontinuous transmission mechanism, and / or a fourth periodic mode of the second cell discontinuous reception mechanism; or. Optionally, the second information includes a second index value, and the second index value is used to index the second connected cell discontinuous transmission mechanism that the network device has configured, and / or the second connected cell discontinuous reception mechanism that has been configured.

[0101] The specific content of the second information is similar to that of the first information, and can be found in the previous text, so it will not be repeated here.

[0102] It should be noted that the first information and the second information sent by the network device to the terminal device can indicate the configuration of the network device in the same manner, for example, both adopt a method of separately defining a cell discontinuous mechanism, that is, both the first information and the second information include the periodic pattern of the corresponding cell discontinuous mechanism, or both include an index value for indexing the already configured connected cell discontinuous mechanism. In addition, the first information and the second information can also be in different manners, for example, the first information includes a first periodic pattern, and the second information includes a second index value.

[0103] In the present application, the first information and the second information can both define the cell discontinuous mechanism separately, or reuse the cell discontinuous mechanism that has been configured by the network device based on the index value, which enriches the implementation method and application scenario of the technical solution of the present application and improves the flexibility of the technical solution of the present application. In the scheme where the first information is defined separately, the terminal device can directly obtain the cell discontinuous mechanism configured by the network device according to the first information, which is simple to operate. In the scheme where the first information includes the index value, the reuse of the configured cell discontinuous mechanism not only reduces the amount of data transmitted by the network device and the terminal device and saves bandwidth resources, but also improves the utilization rate of the configured cell discontinuous mechanism.

[0104] In some optional implementations, there are multiple possibilities for the message carrying the first information and / or the second information, which may be a radio resource control layer message, a medium access control layer message, or a physical layer message.

[0105] In the present application, the first information can be carried in various types of messages, enriching the implementation method of the technical solution of the present application.

[0106] In some optional implementations, the first information is carried in a multicast broadcast control channel for a multicast service, and the second information is carried in a multicast broadcast control channel for a broadcast service.

[0107] In some optional implementations, the first information corresponds to one or more multicast services.

[0108] Exemplarily, the first information corresponds to a multicast service, which means that each first information is associated with a group identifier, which is used to indicate a terminal device that performs the multicast service with the network device. The group identifier can be a group common radio network temporary identity (G-RNTI) or a temporary mobile group identifier (TMGI).

[0109] Exemplarily, the first information corresponds to multiple multicast services, which means that each first information is associated with multiple group identifiers. The multiple multicast services mentioned here may also be all multicast services.

[0110] Similarly, the second information corresponds to one or more broadcast services. The second information corresponds to one broadcast service, which means that each broadcast service corresponds to a service identifier, and the service identifiers of different broadcast services are different. The second information corresponds to multiple broadcast services, that is, multiple broadcast services correspond to the same service identifier. Optionally, the multiple broadcast services can be all broadcast services of the network device.

[0111] Based on the above description, it can be known that the present application has the following beneficial effects: the network device sends a cell discontinuous sending mechanism and / or cell discontinuous receiving mechanism of a multicast service and / or a broadcast service configured by the network device to a terminal device in a non-connected state, thereby realizing that in a multicast service and / or a broadcast service scenario, the network device and the terminal device in a connected state transmit data of related services based on the cell discontinuous mechanism. In other words, for the network device, configuring the cell discontinuous mechanism means that when the network device transmits related data to the terminal device in a non-connected state, it does not need to transmit continuously, but transmits within a specific time period according to the definition of the cell discontinuous mechanism, thereby saving power consumption of the network device.

[0112] After the network device sends the first information to the terminal device, the network device and the terminal device transmit the multicast service data based on the first information. Specifically, the following possible implementation methods are included:

[0113] In some optional implementations, the network device and the terminal device execute step 202. When the first information indicates that the network device configures a first cell discontinuous transmission mechanism for a multicast service, the network device sends first multicast service data to the terminal device within a first activation period defined by the first cell discontinuous transmission mechanism.

[0114] It should be noted that "the network device sends the first multicast service data to the terminal device during the first activation period defined by the discontinuous transmission mechanism of the first cell" does not mean that the network device sends the first multicast service data to the terminal device in each first activator. Rather, it means that for the network device, the time of sending the first multicast service data to the terminal device is included in the first activation period defined by the discontinuous transmission mechanism of the first cell. For the terminal device, the time of receiving the first multicast service data from the network device is included in the first activation period defined by the discontinuous transmission mechanism of the first cell.

[0115] In other words, when the first information instructs the network device to configure the first cell discontinuous sending mechanism of the multicast service, the network device will send the first multicast service data to the terminal device and the terminal device will expect to receive the first multicast service data only during the first activation period defined by the first cell discontinuous sending mechanism.

[0116] In the present application, the network device does not continuously send the first multicast service data to the terminal device, but sends the first multicast service data to the terminal device during the first activation period defined by the discontinuous transmission mechanism of the first cell. In other words, for the network device, during the transmission phase of the relevant data of the multicast service, the network device sends data to the terminal device discontinuously, and the network device does not need to be in the data transmission state all the time, thereby reducing the power consumption of the network device. Correspondingly, the terminal device does not continuously receive the first multicast service data, so that the receiving mechanism of the terminal device matches the sending mechanism of the network device. Then for the terminal device, receiving the first multicast service data during the first activation period defined by the discontinuous transmission mechanism of the first cell can also reduce the power consumption of the terminal device.

[0117] In some optional implementations, the network device and the terminal device perform step 203. When the first information indicates that the network device configures a first cell discontinuous reception mechanism for a multicast service, within a third activation period defined by the first cell discontinuous reception mechanism, the terminal device sends first feedback information for the first multicast service data to the network device.

[0118] It should be noted that "the terminal device sends the first feedback information for the first multicast service data to the network device during the third activation period defined by the discontinuous reception mechanism of the first cell" does not mean that the terminal device sends the first feedback information for the first multicast service data to the network device during each third activation period. Rather, it means that, for the network device, the time when the network device receives the first feedback information from the terminal device is included in the third activation period defined by the discontinuous reception mechanism of the first cell. For the terminal device, the time when the terminal device sends the first feedback information to the network device is included in the third activation period defined by the discontinuous reception mechanism of the first cell.

[0119] In other words, when the first information instructs the network device to configure the first cell discontinuous reception mechanism of the multicast service, the terminal device sends the first feedback information to the terminal device and the network device expects to receive the first feedback information only within the third activation period defined by the first cell discontinuous reception mechanism.

[0120] The first feedback information is used to indicate that the terminal device successfully receives the first multicast service data, or that the terminal device does not receive the first multicast service data, or that the first multicast service data received by the terminal device is incorrect, etc. The fact that the terminal device does not receive the first multicast service data means that part or all of the data packets included in the first multicast service data are not received by the terminal device.

[0121] In the present application, the network device does not continuously receive the first feedback information for the first multicast service data from the terminal device, but receives the first feedback information sent by the terminal device during the third activation period defined by the discontinuous reception mechanism of the first cell. That is to say, for the network device, during the reception phase of the relevant data of the multicast service, the network device receives the data discontinuously, and does not need to be in a data receiving state or prepare for data reception (such as turning on the relevant modules for data reception, etc.) at all times, which further reduces the power consumption of the network device. Accordingly, the terminal device does not continuously send the first feedback information to the network device, so that the sending mechanism of the terminal device matches the receiving mechanism of the network device. Then for the terminal device, sending the first feedback information during the third activation period defined by the discontinuous reception mechanism of the first cell can also reduce the power consumption of the terminal device.

[0122] In some optional implementations, the first information may also instruct the network device to configure a first cell discontinuous transmission mechanism and a first cell discontinuous reception mechanism for a multicast service. The periods corresponding to the first cell discontinuous transmission mechanism and the first cell discontinuous reception mechanism may be the same or different, which is not specifically limited here. The corresponding periods are different, including different period durations, the same period duration but different activation period durations, partial overlap of periods, etc., which are not specifically limited here. For the specific implementation method, please refer to the above description of step 202 and step 203, which will not be repeated here.

[0123] Exemplarily, assuming that the period of the first cell discontinuous transmission mechanism is the same as the period of the first cell discontinuous reception mechanism, then, during the activation period defined by the period, the network device can send the first multicast service data to the terminal device, and the terminal device can send the first feedback information for the first multicast service data to the network device.

[0124] In some optional implementations, the network device and the terminal device execute step 204. When the second information indicates that the network device configures a second cell discontinuous transmission mechanism for a broadcast service, the network device sends the first broadcast service data to the terminal device during a second activation period defined by the second cell discontinuous transmission mechanism.

[0125] It should be noted that "the network device sends the first broadcast service data to the terminal device during the second activation period defined by the discontinuous transmission mechanism of the second cell" does not mean that the network device must transmit the first broadcast service data to the terminal device during each second activation. Rather, it means that for the network device, the time for sending the first broadcast service data to the terminal device is included in the second activation period defined by the discontinuous transmission mechanism of the second cell. For the terminal device, the time for receiving the first broadcast service data from the network device is included in the second activation period defined by the discontinuous transmission mechanism of the second cell.

[0126] In other words, when the second information instructs the network device to configure the second cell discontinuous transmission mechanism of the broadcast service, the network device will send the first broadcast service data to the terminal device and the terminal device will expect to receive the first broadcast service data only during the second activation period defined by the second cell discontinuous transmission mechanism.

[0127] In the present application, the network device does not continuously send the first broadcast service data to the terminal device, but sends the first multicast service data to the terminal device during the third activation period defined by the second cell discontinuous transmission mechanism. That is to say, for the network device, during the transmission phase of the multicast service related data, the network device sends the data to the terminal device discontinuously, and the network device does not need to be in the data transmission state all the time, thereby reducing the power consumption of the network device.

[0128] Accordingly, the terminal device does not continuously receive the first broadcast service data, so that the receiving mechanism of the terminal device matches the sending mechanism of the network device. Then for the terminal device, the first broadcast service data is received only during the second activation period defined by the discontinuous sending mechanism of the first cell, which can also reduce the power consumption of the terminal device.

[0129] In some optional embodiments, the network device and the terminal device execute step 205. When the second information indicates that the network device configures a second cell discontinuous reception mechanism for a broadcast service, within a fourth activation period defined by the second cell discontinuous reception mechanism, the terminal device sends second feedback information for the first broadcast service data to the network device.

[0130] It should be noted that "the terminal device sends the second feedback information for the first broadcast service data to the network device during the fourth activation period defined by the second cell discontinuous reception mechanism" does not mean that the terminal device sends the second feedback information to the network device during each fourth activation period. Rather, it means that, for the network device, the time of receiving the second feedback information from the terminal device is included in the fourth activation period defined by the second cell discontinuous reception mechanism. For the terminal device, the time of sending the second feedback information to the network device is included in the fourth activation period defined by the second cell discontinuous reception mechanism.

[0131] In other words, when the second information instructs the network device to configure the second cell discontinuous reception mechanism of the broadcast service, the terminal device sends the second broadcast service data to the terminal device and the network device expects to receive the second broadcast service data only during the fourth activation period defined by the second cell discontinuous reception mechanism.

[0132] The second feedback information is used to indicate that the terminal device successfully receives the first broadcast service data, or that the terminal device does not receive the first broadcast service data, or that the first broadcast service data received by the terminal device is incorrect, etc. The fact that the terminal device does not receive the first broadcast service data means that part or all of the data packets included in the first broadcast service data are not received by the terminal device.

[0133] In the present application, the network device does not continuously receive the second feedback information from the terminal device, but receives the second feedback information sent by the terminal device during the fourth activation period defined by the discontinuous reception mechanism of the second cell. In other words, for the network device, during the reception phase of the relevant data of the broadcast service, the network device receives the information discontinuously, and does not need to be in a data receiving state or prepare for data reception (such as turning on the relevant modules for data reception, etc.) at all times, which further reduces the power consumption of the network device. Accordingly, the terminal device does not continuously send the second feedback information to the network device, so that the sending mechanism of the terminal device matches the receiving mechanism of the network device. Then for the terminal device, sending the second feedback information during the fourth activation period defined by the discontinuous reception mechanism of the second cell can also reduce the power consumption of the terminal device.

[0134] It should be noted that the terminal device in the inactive state has no feedback mechanism. In this scenario, the network device does not need to configure the cell discontinuous reception mechanism. That is, the non-connected state terminal used in step 203 and step 205 does not include the terminal in the inactive state, but the terminal in the idle state.

[0135] In some optional implementations, the second information may also instruct the network device to configure a second cell discontinuous transmission mechanism and a second cell discontinuous reception mechanism for the broadcast service. The periods corresponding to the second cell discontinuous transmission mechanism and the second cell discontinuous reception mechanism may be the same or different, which is not specifically limited here. The corresponding periods are different, including different period durations, the same period duration but different activation period durations, partial overlap of periods, etc., which are not specifically limited here. For the specific implementation method, please refer to the above description of step 204 and step 205, which will not be repeated here.

[0136] In some optional implementations, the period corresponding to the cell discontinuous mechanism of the multicast service configured by the network device may be the same as or different from the period corresponding to the cell discontinuous mechanism of the broadcast service, which is not specifically limited here. Among them, the corresponding periods are different, including different period durations, the same period duration but different activation period durations, partial overlap of periods, etc., which are not specifically limited here. In other words, the period corresponding to a certain cell discontinuous mechanism may be used by a single service or shared by multiple services, which is not specifically limited here.

[0137] Furthermore, different cell discontinuous mechanisms correspond to the same period, which means that different types of data can be transmitted between the network device and the terminal device in the same time period. In other words, different cell discontinuous mechanisms can share the same period. For example, it is assumed that the first cell discontinuous transmission mechanism of the multicast service has the same period as the second cell discontinuous transmission mechanism of the broadcast service, that is, the first activation period and the second activation period mentioned above actually use one activation period. Then during the activation period, the network device can send at least one of the first multicast service data or the first broadcast service data to the terminal device. In this example, the broadcast service and the multicast service share the same period.

[0138] In some optional implementations, the network device also indicates whether the configuration of the network device has changed through the downlink control information of the MCCH. Specifically, in the DCI of the MCCH for multicast services and / or broadcast services, 1 bit is included to indicate whether the configuration of the cell discontinuous mechanism indicated by the MCCH has changed. The network device sends the DCI to the terminal device, and the terminal device determines whether the configuration of the cell discontinuous mechanism of the network device has changed by reading the information of this 1 bit. In the case of a change, the terminal device further reads other information in the MCCH and synchronizes the change based on the other information to ensure that the terminal device matches the network device.

[0139] Among them, the configuration change of the cell discontinuous mechanism of the network device includes various possible situations, such as: the network device adds a new cell discontinuous mechanism (for example, configures a cell discontinuous mechanism for a new multicast service), deletes a cell discontinuous mechanism (for example, deletes the cell discontinuous mechanism of a multicast service that has been transmitted), or updates the configured cell discontinuous mechanism (for example, modifying the discontinuous period, modifying the activation period, etc.), which is not limited here.

[0140] In the present application, the DCI of the MCCH indicates whether the configuration of the cell discontinuous mechanism indicated by the MCCH has changed, which can avoid the terminal device from updating the relevant configuration unnecessarily and save the power consumption of the terminal device.

[0141] Next, the related equipment provided in the embodiments of the present application is described.

[0142] See also Figure 4 , Figure 4 This is a schematic diagram of the structure of a communication device provided in an embodiment of the present application. Figure 4 As shown, the communication device 400 includes a transceiver unit 401. Optionally, in the embodiment of the present application, the communication device 400 can be used as a network device to implement the following operations:

[0143] In some optional embodiments, the transceiver unit 401 is used to send first information or second information to a terminal device in a non-connected state, the first information instructs the network device to configure a first cell discontinuous sending mechanism and / or a first cell discontinuous receiving mechanism for a multicast service, and the second information instructs the network device to configure a second cell discontinuous sending mechanism and / or a second cell discontinuous receiving mechanism for a broadcast service.
