Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method, device and system. Background Art

[0002] In order to improve the communication rate, the 3rd generation partnership project (3GPP) introduced a carrier aggregation (CA) technology, which aggregates multiple continuous or non-continuous component carriers (CC). Therefore, this technology improves the utilization of bandwidth, thereby achieving the purpose of improving the communication rate. The component carrier accessed by the user is the primary component carrier (PCC), and the cell where the PCC is located is the primary cell (PCell). The multiple carriers corresponding to the bandwidth used by CA, except for PCC, can be called secondary component carriers (SCC), and the cell where the SCC is located is the secondary cell (Scell). CA technology can utilize the resources and advantages of different carriers and different standards to improve the user's uplink and downlink peak rate experience.

[0003] In the scenario of using CA technology, the terminal device can use the secondary cell for data transmission only after the secondary cell is activated. Specifically, when the activation of the secondary cell is performed by the base station, the base station sends an activation signaling to the terminal device. If an ACK is received, the base station will perform a series of actions to activate the secondary cell. Section 5.9 of 3GPP technical standard (technical specification, TS) 38.321 stipulates that the terminal device can report the channel state information (CSI) report of the secondary cell within the specified time after receiving the activation signaling. The data transmission between the terminal device and the base station should be performed after the completion of reporting the channel state information report of the secondary cell, while TS38.213 section 4.3 stipulates that the execution time of reporting the channel state information report of the secondary cell should be later than time T. For example, the base station sends the activation signaling to the terminal device in time slot n, then the value of T is n+k. The specific setting of the k value can refer to the description in TS38.213 section 4.3. Therefore, the efficiency of data transmission in the scenario of CA technology is affected. Summary of the invention

Through this method, after receiving the affirmative response to the activation signaling, the base station actively detects whether the terminal device is ready for data transmission.

It is known to those of ordinary skill in the art that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0035] Figure 1 FIG. 1 is a schematic diagram showing a possible, non-limiting system. Figure 1 As shown, the communication system includes a radio access network (RAN) and a core network (CN). The RAN includes at least one RAN node and at least one user equipment. The RAN may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1The user equipment is connected to the RAN node in a wireless manner. The RAN node is connected to the core network in a wireless or wired manner. The core network device in the core network and the RAN node in the RAN can be different physical devices, or can be the same physical device that integrates the core network logical function and the radio access network logical function.

[0036] RAN may be a cellular system related to the third generation partnership project (3GPP), such as a 4G, 5G mobile communication system, or a future evolution system (such as a 6G mobile communication system). RAN may also be an open access network (open RAN, O-RAN or ORAN), a non-terrestrial network (NTN) system, or a wireless fidelity (WiFi) system. RAN100 may also be a communication system that integrates two or more of the above systems.

[0037] RAN nodes, sometimes also called access network equipment, RAN entities or access nodes, etc., constitute part of the communication system to help terminals achieve wireless access. Multiple RAN nodes in a communication system can be nodes of the same type or nodes of different types. RAN nodes and user equipment are sometimes referred to as communication devices.

[0038] In one possible scenario, the RAN node may be a base station, a satellite base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a 6th 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 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 cloud radio access network (CRAN) scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an onboard device. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU).

[0039] In another possible scenario, multiple RAN nodes collaborate to assist user equipment in achieving 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), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU) or an active antenna unit (AAU).

[0040] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0041] User equipment (UE) can also be called terminal, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, user device, target terminal. The terminal can be a passive IoT terminal or a tag. The terminal can be a passive device, which can be a passive tag. The passive tag can collect energy through backscattering technology to send and receive messages. Passive tags include but are not limited to radio frequency identification (RFID), Bluetooth, Zigbee and other non-powered terminal tags. The terminal can also be a semi-passive device or an active device. The active device may be a device with wireless transceiver function, such as a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a 5G mobile communication system or a terminal in a future evolution network, etc. Wearable devices can also be called wearable smart devices, which are a general term for wearable devices that use wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but also realize powerful functions through software support, data interaction, and cloud interaction.In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0042] The above-mentioned functional network element can be a network element in a hardware device, a software function running on dedicated hardware, or a virtualized function instantiated on a platform (e.g., a cloud platform). The above-mentioned functional network element can be divided into one or more services, and further, there may be services that exist independently of the network function. In this application, an instance of the above-mentioned functional network element, or an instance of a service included in the above-mentioned functional network element, or an instance of a service that exists independently of the network function can be referred to as a service instance. For ease of description, the RAN node in this application is described as a base station.

[0043] In order to improve the communication rate, the 3rd generation partnership project (3GPP) introduced a carrier aggregation (CA) technology, which aggregates multiple continuous or non-continuous component carriers (CC). Therefore, this technology improves the utilization of bandwidth, thereby achieving the purpose of improving the communication rate. The component carrier accessed by the user is the primary component carrier (PCC), and the cell where the PCC is located is the primary cell (PCell). The multiple carriers corresponding to the bandwidth used by CA, except for PCC, can be called secondary component carriers (SCC), and the cell where the SCC is located is the secondary cell (Scell). CA technology can utilize the resources and advantages of different carriers and different standards to improve the user's uplink and downlink peak rate experience.

[0044] In the scenario of using CA technology, the terminal device can use the secondary cell for data transmission (sending uplink data or receiving downlink data) only after the secondary cell is activated. Specifically, when the activation of the secondary cell is performed by the base station, the base station sends an activation signaling to the terminal device, for example, a medium access control-control element (MAC-CE). Subsequently, if the terminal device sends an acknowledgement (ACK) to the base station, the base station will perform a series of actions to activate the secondary cell. Section 5.9 of 3GPP technical standard (TS) 38.321 stipulates that the terminal device can send a channel sounding reference signal (SRS) on the secondary cell, report the channel state information (CSI) report of the secondary cell, and detect the physical downlink control channel (PDCCH) on the secondary cell within a specified time after receiving the activation signaling. Data transmission between the base station and the terminal device should be performed after the channel state information report of the secondary cell is reported. However, TS38.213 Section 4.3 stipulates that the execution time of reporting the channel state information report of the secondary cell should be later than time T. For example, the base station sends activation signaling to the terminal device in time slot n, then the value of T is n+k. The specific setting of the k value can refer to the description in TS38.213 Section 4.3, which will not be repeated here. However, the terminal device may have prepared data transmission before reporting the channel state information report of the secondary cell, thus affecting the efficiency of data transmission in the CA technology scenario.

[0045] Therefore, the present application introduces a communication method for solving the above problems.

[0046] Figure 2 A communication method provided by the present application. The method is described by taking the wireless access network as a base station and the user equipment as a terminal device as an example, wherein it can be understood that the primary cell and the secondary cell can be provided by the same base station or by different base stations, and the present application is not limited thereto.

[0047] Figure 3 The present application provides a flow chart of a communication method, which is described from the perspective of a base station. Figure 2 and Figure 3 , the method may include the following steps:

[0048] Step 201: The base station sends an activation signaling to the terminal device.

[0049] Correspondingly, the terminal device receives activation signaling from the base station.

[0050] The activation signaling is used to activate the secondary cell of the base station. For example, the activation signaling may be MAC-CE.

[0051] Step 202: The terminal device sends a first affirmative response to the base station.

[0052] Correspondingly, the base station receives a first positive response from the terminal device.

[0053] For example, when the terminal device correctly verifies the activation signaling, step 202 is executed. Wherein, correct verification can also be understood as successful verification, or understood as successful analysis, which is not limited in this application. Figure 3 A2 in the above embodiment, and then execute step 203.

[0054] The first positive response is a response to the activation signaling in step 201. For example, the first positive response includes a hybrid automatic repeat request-acknowledgment (HARQ-ACK).

[0055] It is understandable that before step 202 is executed, if the terminal device fails to verify the activation signaling, the terminal device sends a first negative acknowledgment (NACK) to the base station. Figure 3 A1 in. For example, the first negative acknowledgement is a hybrid automatic repeat request-negative acknowledgement (HARQ-NACK). Then, after receiving the first negative acknowledgement, the base station will execute step 201 again until step 202 is executed. The base station may execute step 201 immediately after receiving the first negative acknowledgement, or may wait for a period of time before executing step 201. The time for executing step 201 may be set according to actual product requirements, and this application does not limit it.

[0056] Step 203: The base station sends a detection data packet to the terminal device.

[0057] The detection data packet is used to detect whether the terminal device is ready for data transmission, that is, whether the terminal device is ready to receive downlink data or whether it is ready to send data (send uplink data). In the present application, data transmission may include transmission of data in at least one direction of uplink or downlink.

[0058] For example, the detection data packet can be a filling data packet or a control data packet, wherein the control data packet can also be called a control frame, and the filling data packet can also be called a water injection data packet or a padding data packet. In a specific implementation form, when the detection data packet is a data filling packet, the value of the logical channel identifier (logical channel ID, LCID) of the media access control header of the data filling packet is 63, or any one of the reserved values ​​35 to 46. It can be understood that in a specific implementation, a data filling packet whose LCID value is not equal to 63 can also be used as a detection data packet, depending on the specific implementation.

[0059] Step 204: The terminal device sends a second affirmative response to the base station.

[0060] The second positive response is a response to detecting the data packet in step 203 .

[0061] The second positive response may be the same as the first positive response or different from the first positive response. Here, the same means that the data structure or information content included in the second positive response is the same as that of the first positive response data packet. For example, the first positive response and the second positive response are both hybrid automatic repeat request confirmations. Different means that the data structure or information content included in the two are different. This application is not limited.

[0062] For example, when the terminal device is ready for data transmission, step 204 is executed. It can also be understood that the second positive response data packet is used to inform the base station that the terminal device is ready for data transmission, or that the terminal device can perform data transmission. Figure 3 B2 in the above, and then execute step 205.

[0063] Of course, the premise for executing this step is that the terminal device correctly parses the detection data packet in step 203. If the terminal device cannot correctly parse the detection data packet, the terminal device sends a second negative response to the base station.

[0064] Similarly, before step 204 is executed, if the terminal device is not ready for data transmission, the terminal device sends a second negative response to the base station, such as Figure 3 Then, after receiving the second negative response, the base station will execute step 203 again. The base station may execute step 203 immediately after receiving the second negative response, or may wait for a period of time before executing step 203, which is not limited in the present application.

[0065] Step 205: Data transmission.

[0066] The base station can initiate the transmission of data, that is, the base station sends data to the terminal device.

[0067] In addition, the terminal device can also initiate data uploading, that is, the terminal sends data to the base station.

[0068] In one possible situation, after the first time has passed, or immediately, step 206 is executed. The length of the first time is not limited.

[0069] A possible implementation method is to complete synchronization between the terminal device and the base station before executing step 203 or before executing step 205. For example, the synchronization is synchronization signal block (SSB) synchronization.

[0070] Step 206: The terminal device sends a channel state information report of the secondary cell to the base station.

[0071] For the provisions on the uplink transmission time of the channel state information report, please refer to the description in Section 4.3 of TS38.213 and Section 8.3.2 of TS38.133 in 3GPP, which will not be repeated here.

[0072] Subsequently, the uplink data transmission of the terminal device can continue, and the base station can send downlink data to the terminal device.

[0073] Through the above method, after receiving the positive response of the activation signaling, the base station actively detects whether the terminal device is ready for data transmission. If the terminal device is ready for data transmission, both parties can perform data transmission without waiting until the terminal device sends the channel state information report of the secondary cell to the base station before transmitting data, thereby advancing the data transmission time, saving the waiting time, improving data transmission efficiency, and reducing communication delay. This method also improves the flexibility of communication and can also improve the user experience.

[0074] It should be understood that the CA scenarios to which this embodiment is applicable may include but are not limited to multi-CC scenarios, such as 2CC, 3CC, 4CC, 5CC, etc., and may also be applicable to low-frequency CA, high-frequency CA, and high-low-frequency CA scenarios.
