Description

Technical Field

[0001] This application belongs to the field of communication technology technology, specifically relating to a data processing method, apparatus, communication equipment, system, and storage medium. Background Technology

[0002] In multipath scenarios, multiple terminals can collaborate to transmit data. For example, terminal 1 can directly upload data packets a and b to the network-side device, and terminal 2 can upload data packets c and d of terminal 1 to the network-side device.

[0003] However, if the delay of data packet b exceeds a certain time threshold, at least one subsequent data packet (e.g., data packet c) will time out even if it is successfully transmitted. But according to the above method, since terminal 2 will still upload data packets c and d to the network device when the delay of data packet b exceeds the certain time threshold, terminal 2 will perform unnecessary data transmission, thus wasting transmission resources.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.

[0033] The data processing method, apparatus, communication device, system, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0034] Relay technology in wireless communication systems involves adding one or more relay nodes between the base station and the terminal. These relay nodes are responsible for forwarding the wireless signal one or more times, meaning the wireless signal must travel through multiple hops to reach the terminal. Taking two-hop relay as an example, a base station-terminal link in a wireless communication system can be split into two links: base station-relay station and relay station-terminal. This allows a low-quality link to be replaced with two high-quality links, resulting in higher link capacity and better coverage. Relay technology can not only extend the coverage area of ​​a cell and fill coverage blind spots, but also improve cell capacity through spatial resource reuse. For indoor coverage, relay technology can also overcome penetration loss and improve indoor coverage quality.

[0035] In LTE, the currently supported relay is UE-to-Network relay, where one end of the relay connects to the UE and the other end connects to the network. The UE connected to the relay is the remote UE. NR will also investigate how to support the UE-to-NetworkRelay mechanism so that, in situations with poor signal coverage, remote UEs can transmit data to the network via a relay UE. The relay UE and the network are connected via an air interface (Uu interface), and the relay UE and the remote UE are connected via an SL interface (e.g., PC5 interface). Generally, the relay UE is open and can serve any remote UE.

[0036] In the SL Relay scenario, a Radio Resource Control (RRC) connection can be established through the following steps.

[0037] Step 1. The Remote UE and Relay UE perform the discovery process and establish a PC5 RRC connection.

[0038] Step 2. The Remote UE sends an RRC Setup Request message to the base station, and the base station replies to the Remote UE with an RRC Setup message. Specifically, these two messages can be relayed from the Relay UE to the base station or the Remote UE.

[0039] Step 3. Establish a dedicated signaling radio bearer 1 (SRB1) between the base station and the Remote UE. The Remote UE SRB1 dedicated bearer consists of two radio link control (RLC) channels: PC5 (between the Remote UE and the Relay UE) and Uu (between the Relay UE and the base station). These two RLC channels are used for the Remote UE to send / receive SRB1 type RRC messages with the base station.

[0040] Step 4. The Remote UE sends an RRC setup complete (RRCSetupComplete) message to the base station. Specifically, this message can be relayed to the base station by the Relay UE.

[0041] Step 5. Activate security between the remote UE and the base station; wherein the security activation messages and procedures reuse existing mechanisms.

[0042] Step 6. Establish a dedicated SRB2 / Data Radio Bearer (DRB) bearer between the base station and the Remote UE. The Remote UE SRB2 / DRB dedicated bearer consists of two RLC channels, PC5 and Uu. These two RLC channels are used for the Remote UE to send / receive SRB2 type RRC / Network Attached Server (NAS) messages and uplink / downlink service data with the base station. Specifically, this can be achieved by reusing the existing RRC reconfiguration mechanism.

[0043] Currently, relay technology can be applied to multiple UEs cooperating in data transmission in multipath scenarios. Multipath refers to a UE simultaneously establishing both indirect and direct paths. An indirect path is a radio link where the UE establishes an RRC connection with the base station through the Uu air interface of the Relay UE (or secondary UE) and the Relay UE (or secondary UE). A direct path is a radio link where the UE establishes an RRC connection with the base station through its own Uu air interface.

[0044] The following section, with reference to the accompanying diagram, provides a detailed explanation of the method for two UEs to collaboratively transmit data in a multipath scenario.

[0045] For example, such as Figure 2As shown in (a), assuming that data packets 1 to 5 are the data packets that UE1 needs to upload to the NR node (NR Node B, gNB), then UE1 can upload data packets 1 and 2 to the gNB through the Uu interface, and can transmit data packets 3, 4, and 5 to UE2 through the PC5 interface, and UE2 can cooperate in uploading data packets 3, 4, and 5 to the gNB; Figure 2 As shown in (b), assuming that data packets 1 to 5 are the data packets that UE3 needs to upload to the gNB, then UE3 can transmit data packets 1 and 2 to UE1 through the PC5 interface, and transmit data packets 3, 4, and 5 to UE2. UE1 and UE2 can then collaborate to upload data packets 1 to 5 to the gNB. In this way, two UEs can collaborate to transmit data in a multipath scenario.

[0046] For the SL relay architecture, the two UEs are connected via the PC5 interface, such as Figure 3 As shown, multipathing in the SL relay architecture refers to the Remote UE establishing both indirect and direct paths simultaneously; however, in non-SL relay architectures, the two UEs are not connected via the PC5 interface, as... Figure 4 As shown, assuming the interface between the primary UE (i.e., the primary UE) and the secondary UE is an ideal inter-UE connection, then multiple paths mean that the primary UE establishes both an indirect path and a direct path.

[0047] However, for services with high latency requirements (such as playing real-time comments), if the latency of a data packet exceeds a certain time threshold T, then even if the second data packet is successfully transmitted, its timeout will also occur. In this case, the network can instruct the UE to discard the second data packet. In the aforementioned multipath scenario, if UE1 and UE2 cooperate in transmitting data, if UE2 continues to transmit data when the data packet in UE1's path times out, it will result in a waste of transmission resources.

[0048] To address the aforementioned issues, in the data processing method provided in this application embodiment, during the process of UE1 and UE2 collaboratively acquiring first data, if a first condition is met, UE1 can instruct UE2 and / or gNB to discard data packets transmitted after the timed-out acquired data packets. This eliminates the need for UE2 and / or gNB to perform unnecessary data transmission, thus saving transmission resources when multiple UEs are collaboratively transmitting data.

[0049] This application provides a data processing method. Figure 5 A flowchart illustrating the data processing method provided in an embodiment of this application is shown. Figure 5 As shown, the data processing method provided in this application embodiment may include the following step 501.

[0050] Step 501: During the process of the first terminal cooperating with at least one second terminal to obtain the first data, if the first condition is met, the first terminal instructs the first device to discard the first data packet in the first data.

[0051] In this embodiment of the application, the first device includes at least one of the following: at least one second terminal, or a network-side device.

[0052] In this embodiment of the application, the first condition includes: obtaining the second data packet after the timer corresponding to the second data packet in the first data expires.

[0053] In this embodiment of the application, the first data packet is the data packet transmitted after the second data packet.

[0054] Optionally, in this embodiment of the application, the second data packet can be at least one data packet transmitted after the first data packet and adjacent to the first data packet.

[0055] For example, suppose the first data includes data packet 1, data packet 2, data packet 3 and data packet 4, and the transmission order of the data packets in the first data is data packet 1 to data packet 4. If the first data packet is data packet 1, then the second data packet can be data packet 2, or it can be data packet 2 and data packet 3, etc.

[0056] Optionally, in this embodiment of the application, the number of the above-mentioned at least one data packet can be determined according to the service corresponding to the first data.

[0057] Optionally, in this embodiment of the application, the first data may be the data that the network-side device needs to transmit to the first terminal.

[0058] Optionally, in this embodiment of the application, the first terminal and the at least one second terminal can obtain at least a portion of the data in the first data through their respective Uu interfaces, and the at least one second terminal can transmit the obtained data to the first terminal, so that the first terminal can obtain the first data through cooperation between the first terminal and the at least one second terminal.

[0059] Optionally, in this embodiment of the application, the first device includes at least one second terminal: at least one of the above-mentioned at least one second terminal that cooperates with the first terminal to obtain the first data.

[0060] It is understood that when the first terminal obtains the first data from the network-side device in cooperation with at least one of the second terminals, if the first condition is met, the first terminal may instruct at least one of the second terminals and / or the network-side device to discard the first data packet, thereby causing the at least one second terminal and / or the network-side device to stop transmitting the first data packet.

[0061] Optionally, in this embodiment of the application, the timer corresponding to the second data packet can be a timer maintained by the first terminal, or a timer configured by the network-side device.

[0062] Optionally, in the embodiments of this application, each data packet may correspond to a timer, or each group of data packets (i.e., at least two consecutive data packets) may correspond to a timer; and each pair of timers may be the same or different.

[0063] Optionally, in this embodiment of the application, the timer corresponding to the second data packet is started by the first terminal when it obtains the third data packet in the first data.

[0064] The third data packet is a data packet that is transmitted before the second data packet and is adjacent to the second data packet.

[0065] Optionally, the timer corresponding to the second data packet being started by the first terminal when it receives the third data packet in the first data can be understood as: the timer corresponding to the second data packet being started when the first terminal successfully receives the third data packet.

[0066] Optionally, in embodiments of this application, the third data packet may include one or multiple consecutive data packets.

[0067] Optionally, in this embodiment of the application, if the second data packet is acquired within the timer corresponding to the second data packet, the first terminal may stop the timer and start the timer corresponding to the next transmitted data packet, or start the timer corresponding to the next group of transmitted data packets; if the second data packet is acquired after the timer corresponding to the second data packet has expired, the first terminal may instruct the first device to discard the first data packet.

[0068] In this embodiment of the application, since the timer corresponding to the second data packet is started by the first terminal when the third data packet is acquired, the timer corresponding to the second data packet can be started when the acquisition of the second data packet begins, so as to accurately monitor whether the acquisition of the second data packet has timed out.

[0069] In the data processing method provided in this application embodiment, since the first terminal, in the process of cooperating with at least one second terminal to obtain the first data, can instruct at least one second terminal and / or network-side device to discard the data packets transmitted after the data packets obtained after the timeout are met when the first condition is met, the at least one second terminal and / or network-side device can avoid unnecessary data transmission, thereby saving transmission resources when multiple terminals cooperate to transmit data.

[0070] Optionally, in the embodiments of this application, before step 501 above, the data processing method provided in the embodiments of this application may further include step 502 below.

[0071] Step 502: The first terminal receives configuration information from the network-side device.

[0072] In this embodiment of the application, the above configuration information is used for the first terminal to cooperate with at least one second terminal to transmit data.

[0073] Optionally, in this embodiment of the application, if the at least one second terminal is in a connected state, the at least one second terminal also receives the configuration information from the network-side device, so that the first terminal and the at least one second terminal can cooperate to transmit data through the configuration information.

[0074] Optionally, in this embodiment of the application, if the at least one second terminal is in a disconnected state, the at least one second terminal can first enter the connection through paging by the network-side device, and then receive the configuration information from the network-side device.

[0075] In this embodiment, since the first terminal can receive configuration information from the network-side device, the first terminal can cooperate with at least one second terminal to transmit data through the configuration information, thereby ensuring that the first terminal and the at least one second terminal can synchronously cooperate to transmit data.

[0076] Optionally, in this embodiment of the application, the above configuration information may include at least one of the following:

[0077] (1) Wireless bearer configuration of the link between the first terminal and each second terminal;

[0078] (2) Wireless bearer configuration of the Uu DRB of the first terminal;

[0079] (3) Radio bearer configuration of at least one second terminal's Uu DRB;

[0080] (4) Configuration of two paths associated with the Packet Data Convergence Protocol (PDCP) (e.g., More Than Two RLC-DRB configuration of two paths);

[0081] (5) Quality of Service (QoS) flow information;

[0082] (6) Information indicating that the first terminal is activated to transmit data on both paths;

[0083] (7) Information indicating that at least one second terminal is activated to transmit data on both paths.

[0084] In this embodiment of the application, since the above configuration information may include at least one of (1) to (7) above, the flexibility of configuring the first terminal to cooperate with at least one second terminal to transmit data can be improved.

[0085] Alternatively, the two paths mentioned above can be understood as: two RLC paths or two RLC entities.

[0086] Optionally, in this embodiment of the application, before step 502 above, the data processing method provided in this embodiment of the application may further include step 503 below.

[0087] Step 503: If the second condition is met, the first terminal sends a request message to the network-side device.

[0088] In this embodiment of the application, the above-mentioned request information is used to request cooperation with the above-mentioned at least one second terminal to transmit data.

[0089] Optionally, in this embodiment, the request information can be used to request the network-side device to configure the first terminal to cooperate with at least one second terminal in transmitting data for a QoS flow and / or a DRB.

[0090] In this embodiment of the application, the second condition includes at least one of the following:

[0091] The reference signal receiving power (RSRP) of the first terminal Uu is less than or equal to the first RSRP threshold;

[0092] The RSRP of the link between the first terminal and at least one of the second terminals is greater than or equal to the second RSRP threshold.

[0093] Optionally, in this embodiment of the application, the first RSRP threshold and the second RSRP threshold can be configured, predefined, or agreed upon by the protocol.

[0094] It is understandable that when the RSRP of the first terminal's Uu is less than or equal to the first RSRP threshold, the efficiency of the first terminal's Uu in transmitting data is poor; when the RSRP of the link between the first terminal and at least one of the above-mentioned second terminals (e.g., PC5) is greater than or equal to the second RSRP threshold, the efficiency of the link between the first terminal and the at least one second terminal in transmitting data is good.

[0095] In this embodiment of the application, since the first terminal can send a request message to the network-side device to request cooperation with at least one second terminal to transmit data when the second condition is met, the efficiency of the first terminal in obtaining data can be improved.

[0096] Optionally, in this embodiment of the application, the above-mentioned request information may include at least one of the following:

[0097] (1.1) Identification information of at least one second terminal;

[0098] (1.2) The first terminal requires the service QoS flow information to be transmitted through at least one of the above-mentioned second terminals;

[0099] (1.3) The first terminal requires the service DRB information to be transmitted through at least one of the above-mentioned second terminals.

[0100] In this embodiment of the application, since the above request information may include at least one of (1.1) to (1.3) above, the flexibility of requesting the network-side device to configure the first terminal to cooperate with at least one second terminal to transmit data for a QoS flow and / or a DRB can be improved.

[0101] Optionally, in the embodiments of this application, step 503 above can be specifically implemented by step 503a below.

[0102] Step 503a: The first terminal sends a request message to the network-side device through the Uu of the first terminal or the Uu of a second terminal.

[0103] In this embodiment of the application, since the first terminal can send request information to the network-side device through the Uu of the first terminal or the Uu of a second terminal, the flexibility of sending request information to the network-side device can be improved.

[0104] It is understood that when the second condition is met, the first terminal can first send the above request information to the network-side device through the Uu of the first terminal or the Uu of a second terminal, in order to request the network-side device to configure the first terminal and at least one second terminal to cooperate in transmitting data for a QoS flow and / or a DRB; then, after receiving the request information, the network-side device can send configuration information to configure the first terminal and the at least one second terminal to cooperate in transmitting data; thus, the first terminal and the at least one second terminal can receive the configuration information and cooperate in transmitting data through the configuration of the configuration information.

[0105] This application provides a data processing method. Figure 6 A flowchart illustrating the data processing method provided in an embodiment of this application is shown. Figure 6 As shown, the data processing method provided in this application embodiment may include the following step 601.

[0106] Step 601: During the process of the network-side device obtaining the second data through the cooperation of the first terminal and at least one second terminal, if the third condition is met, the network-side device instructs the second device to discard the fourth data packet in the second data.

[0107] In this embodiment of the application, the second device includes at least one of the following: a first terminal, and at least one second terminal.

[0108] In this embodiment of the application, the third condition includes any one of the following:

[0109] (A) The fifth data packet is obtained after the timer corresponding to the fifth data packet in the second data expires;

[0110] (B) The fifth data packet and the fourth data packet in the second data are data packets obtained by different terminals at the same time, and the network side device did not obtain the fourth data packet.

[0111] In this embodiment of the application, in (A) above, the timer corresponding to the fifth data packet is configured by the network-side device according to the first information, which includes at least one of the following: an uplink grant (UL grant) granted by the network-side device to the first terminal or at least one of the second terminals; a synchronization time maintained by the network-side device and the terminal; and the predetermined timestamp can be a timestamp maintained by the network-side device.

[0112] Optionally, in this embodiment of the application, if the third condition includes (A) above, the second data can be the data that the first terminal needs to transmit to the network-side device; the fourth data packet is the data packet transmitted after the fifth data packet.

[0113] Optionally, in this embodiment of the application, the timer corresponding to the fifth data packet is started by the network-side device when it obtains the sixth data packet in the second data.

[0114] The sixth data packet is a data packet that is transmitted before the fifth data packet and is adjacent to the fifth data packet.

[0115] In this embodiment, since the timer corresponding to the fifth data packet is started by the network-side device when the sixth data packet is acquired, the timer corresponding to the fifth data packet can be started when the acquisition of the fifth data packet begins, thereby accurately monitoring whether the acquisition of the fifth data packet has timed out.

[0116] Optionally, in the embodiments of this application, in (B) above, the fifth data packet and the fourth data packet can be data packets from different data sources.

[0117] For example, taking the third condition including (B) above as an example, assuming that the network-side device obtains the second data through cooperation between UE1 (i.e., the first terminal) and UE2 (i.e., at least one second terminal), if the time when UE1 obtains data packet a (i.e., the fifth data packet) is the same as the time when UE2 obtains data packet b (i.e., the fourth data packet), and the network-side device obtains data packet a but not data packet b, then the network-side device can instruct UE2 (i.e., the second device) to discard data packet b. This can save transmission resources for UE2. Optionally, in this embodiment, if the network-side device does not obtain the fifth data packet, at least one second terminal can discard the fourth data packet according to the instruction of the first terminal.

[0118] It is understood that if the first terminal fails to transmit the fifth data packet correctly, the first terminal may instruct at least one second terminal that the fifth data packet has failed to be transmitted correctly, and the at least one second terminal may discard the fourth data packet upon receiving the instruction.

[0119] In this embodiment of the application, since at least one second terminal can discard the fourth data packet according to the instruction of the first terminal when the network-side device does not obtain the fifth data packet, the first terminal can instruct at least one second terminal to discard the corresponding data packet according to its own data transmission situation without going through the network-side device, thereby reducing the power consumption of each device and saving the transmission resources of the at least one second terminal.

[0120] For other descriptions in the embodiments of this application, please refer to the relevant descriptions in the above terminal-side embodiments. To avoid repetition, they will not be repeated here.

[0121] In the data processing method provided in this application embodiment, since the network-side device can instruct the first terminal and / or at least one second terminal to discard data packets transmitted after the timeout data packets are discarded when a third condition is met during the process of obtaining second data through cooperation between the first terminal and at least one second terminal, the first terminal and / or the at least one second terminal can avoid unnecessary data transmission, thereby saving transmission resources when multiple terminals cooperate to transmit data.

[0122] Optionally, in this application embodiment, the third condition includes the above (A). Therefore, before step 601 above, the data processing method provided in this application embodiment may also include the following step 602.

[0123] Step 602: The network-side device receives the request information sent by the first terminal.

[0124] In this embodiment of the application, the above-mentioned request information is used to request cooperation with the above-mentioned at least one second terminal to transmit data.

[0125] Optionally, in this embodiment of the application, the above-mentioned request information can be used to request the network-side device to configure the first terminal to cooperate with the above-mentioned at least one second terminal to transmit data for a QoS flow and / or a DRB.

[0126] In this embodiment of the application, since the network-side device can receive a request message sent by the first terminal for requesting to cooperate with at least one second terminal to transmit data, the network-side device can be informed of the cooperation transmission request between the first terminal and the at least one second terminal, thereby improving the accuracy of the network-side device configuration.

[0127] Optionally, in this embodiment of the application, after step 602 above, the data processing method provided in this embodiment of the application may further include step 603 below.

[0128] Step 603: The network-side device sends configuration information to the first terminal and at least one second terminal.

[0129] In this embodiment of the application, the above configuration information includes at least one of the following:

[0130] (1) Wireless bearer configuration of the link between the first terminal and each second terminal;

[0131] (2) Wireless bearer configuration of the Uu DRB of the first terminal;

[0132] (3) Radio bearer configuration of at least one second terminal's Uu DRB;

[0133] (4) Configuration of the two paths associated with PDCP;

[0134] (5) QoS flow information;

[0135] (6) Information indicating that the first terminal is activated to transmit data on both paths;

[0136] (7) Information indicating that at least one second terminal is activated to transmit data on both paths.

[0137] Optionally, in this embodiment of the application, after the network-side device configures the first terminal to cooperate with the at least one second terminal to transmit data, the first terminal can exchange the association relationship of data packets with the at least one second terminal (for example, the first terminal transmits data packets 1, 2 and 3, and the first terminal transmits data packets 3, 4 and 5 through a second terminal).

[0138] In this embodiment of the application, since the network-side device can send configuration information to the first terminal and at least one second terminal, and the configuration information may include at least one of (1) to (7) above, the flexibility of the network-side device in configuring the first terminal and the at least one second terminal to cooperate in transmitting data can be improved.

[0139] Optionally, in this application embodiment, the third condition includes the above (B). Therefore, before step 601 above, the data processing method provided in this application embodiment may further include the following step 604.

[0140] Step 604: The network-side device determines the data packets acquired at the same time based on the first configuration of the first terminal and at least one second terminal.

[0141] In this embodiment of the application, the network-side device, the first terminal, and the at least one second terminal use the same timetable. For example, the network-side device synchronizes its timetable with the first terminal and the at least one second terminal.

[0142] In this embodiment of the application, the first configuration includes at least one of the following:

[0143] (a) Configure data collection at the same time;

[0144] (b) Configure data to be reported at the same time;

[0145] (c) Configure the cycle for repeated data collection and reporting;

[0146] (d) Configure the pairing relationship between the data acquisition time and the Logical Channel Identity (LCH ID);

[0147] (e) When configuring data collection, attach the time of data collection to each data packet group.

[0148] Optionally, in this embodiment of the application, if the first configuration includes (b) above, the network-side device can determine the data packets acquired at the same time based on the time when the first terminal and the at least one second terminal report data.

[0149] For example, taking the first configuration including (d) above as an example, if data packet 1 transmitted by UE1 (i.e., the first terminal) and data packet 2 transmitted by UE2 (i.e., at least one second terminal) are both transmitted using LCH 3, then the network-side device can determine that data packet 1 and data packet 2 are data packets acquired at the same time. Furthermore, the network-side device can also determine data packets acquired at the same time based on the pairing relationship between the periodic data collection time and LCH ID of the configuration of the first terminal and at least one second terminal (e.g., data collected every 10 minutes is transmitted using LCH 3).

[0150] For example, taking the first configuration including (e) above as an example, if UE1 (i.e., the first terminal) collects data packet 1 at 11:20 and UE2 (i.e., at least one second terminal) collects data packet 2 at 11:20, then the network-side device can determine that data packet 1 and data packet 2 are data packets acquired at the same time.

[0151] In this embodiment of the application, since the network-side device can determine the data packets acquired at the same time based on the different first configurations of the first terminal and at least one second terminal, the flexibility of the network-side device in determining the data packets acquired at the same time can be improved.

[0152] For other descriptions in the embodiments of this application, please refer to the relevant descriptions in the above terminal-side embodiments. To avoid repetition, they will not be repeated here.
